ABSTRACT
ObjectiveTo explore the medication characteristics and clinical efficacy of the Tenghuang Jiangu tablets in the treatment of knee osteoarthritis （KOA） in the remission stage in the real world，providing references for rational clinical use of this prescription. MethodBased on the "registration system of KOA treated with Tenghuang Jiangu tablets"，2 439 KOA cases in the remission stage were analyzed by SPSS 25.0，IBM SPSS Modeler18.0，and Apriori algorithm. To be specific，the age，body mass index （BMI），and course of treatment were described in the form of x̄±s. The information on gender，K-L grade，daily dose，and frequency of drug use was described by frequency analysis. The number of cases，course of treatment，daily dose，and drug use frequency of the single-use group and the combined-use group were described by frequency analysis，and the combination of drugs was described by frequency analysis and Apriori algorithm. Mann-Whitney U test was employed to compare the scores of Visual Analogue Scale （VAS），Western Ontario and McMaster Universities Osteoarthritis Index （WOMAC），pain，stiffness，and joint function between the single-use group and the combined-use group. ResultThe results of clinical treatment showed that 2 439 patients with KOA in the remission stage were treated with Tenghuang Jiangu tablets，with 1 432 （58.71%） in the single-use group and 1 007 （41.29%） in the combined-use group. The average daily dose of Tenghuang Jiangu tablets was （3.90±1.44） g，and the majority of the patients were at grade Ⅱ （54.47%）. The daily average daily dose of Tenghuang Jiangu tablets in the single-use group was （3.64±1.35） g，which was lower than that in the combined-use group ［（4.26±1.48） g，P<0.05］. In the combined use，the top three western medicines were glucosamine （270 times，14.68%），sodium hyaluronate （126 times，6.85%），and imrecoxib （116 times，6.31%），and the top three Chinese medicines were Huoxuezhitong capsules/tablets/ointments （31 times，1.69%），Biqi capsules （25 times，1.36%），and Maizhiling （23 times，1.25%）. As for the overall clinical efficacy，the VAS score was （5.13±0.93） score before treatment and （2.22±1.18） score after treatment （P<0.05），with an overall average decrease of （2.91±1.14） score， and the average decrease in the single-use group was （2.76±1.43） score， which was lower than that in the combined-use group ［（3.12±1.36） score，（P<0.01）］. The WOMAC score was （31.05±11.84） score before treatment and （13.55±9.91） score after treatment （P<0.05）. The overall average decrease was （17.50±11.79） score， and the average decrease in the single-use group and combined-use group was （16.39±11.14） score and （19.08±12.50） score，respectively （P<0.01）. The patients with KOA>grade Ⅱ accounted for 91.34%（1 308/1 432） and 93.55%（942/1 007） in the single-use group and combined-use group，respectively （χ2=80.026，P<0.05）. A total of 43.37%（621/1 432） of the patients in the single-use group had other complications，lower than that in the combined-use group ［54.92%（553/1 432），（χ2=20.087，P<0.01）］. ConclusionMore than half of the patients with KOA in the remission stage are treated with Tenghuang Jiangu tablets alone，and the combination therapy is mainly applied in patients with severe conditions or other complications. In relieving knee joint pain and improving joint stiffness and joint function，both the Tenghuang Jiangu tablets alone and the combination therapy are effective.
ABSTRACT
OBJECTIVE@#To compare and analyze the effect of unplanned versus planned admission to the intensive care unit (ICU) on the prognosis of high-risk patients after surgery, so as to provide a clinical evidence for clinical medical staff to evaluate whether the postoperative patients should be transferred to ICU or not after surgery.@*METHODS@#The clinical data of patients who were transferred to ICU after surgery admitted to the Affiliated Hospital of Guizhou Medical University from January to December in 2021 were retrospectively analyzed, including gender, age, body mass index, past history (whether combined with hypertension, diabetes, pulmonary disease, cardiac disease, renal failure, liver failure, hematologic disorders, tumor, etc.), acute physiology and chronic health evaluation II (APACHE II), elective surgery, pre-operative hospital consultation, length of surgery, worst value of laboratory parameters within 24 hours of ICU admission, need for invasive mechanical ventilation (IMV), duration of IMV, length of ICU stay, total length of hospital stay, ICU mortality, in-hospital mortality, and survival status at 30th day postoperative. The unplanned patients were further divided into the immediate transfer group and delayed transfer group according to the timing of their ICU entrance after surgery, and the prognosis was compared between the two groups. Cox regression analysis was used to find the independent risk factors of 30-day mortality in patients transferred to ICU after surgery.@*RESULTS@#Finally, 377 patients were included in the post-operative admission to the ICU, including 232 in the planned transfer group and 145 in the unplanned transfer group (42 immediate transfers and 103 delayed transfers). Compared to the planned transfer group, patients in the unplanned transfer group had higher peripheral blood white blood cell count (WBC) at the time of transfer to the ICU [×109/L: 10.86 (7.09, 16.68) vs. 10.11 (6.56, 13.27)], longer total length of hospital stay [days: 23.00 (14.00, 34.00) vs. 19.00 (12.00, 29.00)], and 30-day post-operative mortality was higher [29.66% (43/145) vs. 17.24% (40/232)], but haemoglobin (Hb), arterial partial pressure of carbon dioxide (PaCO2), oxygenation index (PaO2/FiO2), and IMV requirement rate were lower [Hb (g/L): 95.00 (78.00, 113.50) vs. 98.00 (85.00, 123.00), PaCO2 (mmHg, 1 mmHg ≈ 0.133 kPa): 36.00 (29.00, 41.50) vs. 39.00 (33.00, 43.00), PaO2/FiO2 (mmHg): 197.00 (137.50, 283.50) vs. 238.00 (178.00, 350.25), IMV requirement rate: 82.76% (120/145) vs. 93.97% (218/232)], all differences were statistically significant (all P < 0.05). Kaplan-Meier survival curve showed that the 30-day cumulative survival rate after surgery was significantly lower in the unplanned transfer group than in the planned transfer group (Log-Rank test: χ2 = 7.659, P = 0.006). Univariate Cox regression analysis showed that unplanned transfer, APACHE II score, whether deeded IMV at transfer, total length of hospital stay, WBC, blood K+, and blood lactic acid (Lac) were associated with 30-day mortality after operation (all P < 0.05). Multifactorial Cox analysis showed that unplanned transfer [hazard ratio (HR) = 2.45, 95% confidence interval (95%CI) was 1.54-3.89, P < 0.001], APACHE II score (HR = 1.03, 95%CI was 1.00-1.07, P = 0.031), the total length of hospital stay (HR = 0.86, 95%CI was 0.83-0.89, P < 0.001), the need for IMV on admission (HR = 4.31, 95%CI was 1.27-14.63, P = 0.019), highest Lac value within 24 hours of transfer to the ICU (HR = 1.17, 95%CI was 1.10-1.24, P < 0.001), and tumor history (HR = 3.12, 95%CI was 1.36-7.13, P = 0.007) were independent risk factors for patient death at 30 days post-operative, and the risk of death was 2.45 times higher in patients unplanned transferred than in those planned transferred. Subgroup analysis showed that patients in the delayed transfer group had significantly longer IMV times than those in the immediate transfer group [hours: 43.00 (11.00, 121.00) vs. 17.50 (2.75, 73.00), P < 0.05].@*CONCLUSIONS@#The 30-day mortality, WBC and total length of hospital stay were higher in patients who were transferred to ICU after surgery, and PaO2/FiO2 was lower. Unplanned transfer, oncology history, use of IMV, APACHE II score, total length of hospital stay, and Lac were independent risk factors for patient death at 30 days postoperatively, and patients with delayed transfer to ICU had longer IMV time.

ObjectiveTo investigate the clinical efficacy of Tenghuang Jiangu tablets （THJGT） combined with oral non-steroidal anti-inflammatory drugs （NSAIDs） in the treatment of osteoarthritis of the knee and its applicable stage based on real-world data， and provide a basis for the rational clinical use of THJGT. MethodA total of 218 cases treated with THJGT combined with oral NSAIDs included in the "THJGT for knee osteoarthritis case registry" from September 2019 to January 2021 were selected as the observation group， and 126 cases treated with oral NSAIDs alone as the control group （CG）. The data of gender， age， body mass index， Kellgren-Lawrence grading scale （K-L scale） score， visual analogue score （VAS score）， Western Ontario and McMaster Universities Osteoarthritis Index （WOMAC） score， swelling grade， joint fear of cold score， back pain and weakness score， and occurrence of adverse events/reactions of the patients in both groups were used for the evaluation of efficacy with full analysis set. The propensity score matching method was used to exclude the influence of confounding factors between groups， and the sub-data sets were established， with which the repeated measures analysis of variance （ANOVA） was carried out to evaluate the efficacy. Visit points were at registration， 4 weeks and 8 weeks after registration. The data were statistically analyzed in Excel 2019 and SPSS 23.0. ResultThe proportion of females in the observation group was 66.06% （144/218）， which was higher than that （58.73%， 74/126） in the control group （χ2=1.846）. The average age in the observation group was （61.12±7.01） years， which was higher than that ［（59.38±5.99） years］ in the control group （W=19 918.50， P<0.05）. The remission rate in the observation group was 98.17% （214/218）. In the observation group， the proportions of the patients at K-L grades Ⅱ and Ⅲ were 64.22% （144/218） and 25.23% （55/218）， respectively. The effect analysis of the whole data set for enrollment and treatment for 8 weeks showed that the VAS score of the experimental group decreased by （3.27±1.24） points on average， which was better than that of the control group [（2.75±1.20）， W=34 179.00， P<0.05]. The average WOMAC score decreased （23.43±11.46） points， which was better than that of the control group [（16.71±8.86）， W=32 387.00， P<0.05]. The average swelling grade decreased （0.63±0.64）， which was better than the control group [（0.33±0.59）， W=33 847.50， P<0.05]. The average score of joint chills decreased （1.90±1.84）， points， which was better than that of control group [（1.40±1.28）， W=35 165.00， P<0.05]. The average lumbar acid fatigue score decreased by （2.02±1.64） points, which was better than that of the control group [（1.10±1.28）， W=32 986.50， P<0.05]. Efficacy analysis of subdata sets for enrollment， 4 weeks of medication and 8 weeks of medication showed that VAS scores of both groups showed a downward trend after treatment， and the improvement of experimental group was more significant than that of control group at 4 weeks， with statistical significance （P<0.05）. After treatment， the total WOMAC score of both groups showed a downward trend， and the improvement of experimental groups was more significant at 4 weeks and 8 weeks （P<0.05）. After treatment， swelling， cold fear grade and lumbar acid fatigue score of both groups showed a decreasing trend,， and the improvement of experimental group was more significant at 8 weeks （P<0.05）. The therapeutic effect analysis of patients in the attack stage and remission stage of the experimental group showed that the total WOMAC score of the two groups showed a downward trend after treatment， and the trend was basically the same， and there was no statistical difference between the two groups at enrollment， 4 weeks after treatment， and 8 weeks after treatment （t=1.675， t=2.068， t=2.364）. The total WOMAC score of the patients in remission stage in the experimental group with K-L grading between grade 0 and grade Ⅲ had statistical significance at 4 weeks after treatment compared with the time of entry （P<0.05， P<0.01）. Group of adverse event rate was 4.13% （9/218）， lower than the control group 10.32% （13/126） （χ2= 5.109， P<0.05）. ConclusionThe population receiving THJGT combined with oral NSAIDs is mostly female， old， in remission， and with K-L grades Ⅱ and Ⅲ. THJGT can enhance the anti-inflammatory and analgesic effects of oral NSAIDs and keep the drug effect in improving joint function and alleviating fear of cold， swelling， and back pain and weakness. The drug combination can be applied to patients in both attack and remission， and the clinical application should take patient's disease stage and degree of osteoarthritis into account. Furthermore， the combination has the potential to reduce the incidence of adverse events caused by NSAIDs.
ABSTRACT
ObjectiveTo explore the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis based on real-world data and provide a basis for clinical medication. MethodFrom May 2020 to December 2021， the data of a total of 1 002 patients with knee osteoarthritis who did not undergo knee joint replacement surgery was collected through the registration method. 952 patients were ultimately included， including 133 cases orally taking Osteoking combined with non-steroidal anti-inflammatory drugs as the observation group and 73 cases orally taking non-steroidal anti-inflammatory drugs alone as the control group. Statistical analysis was conducted on the baseline data， VAS scores， WOMAC scores， and other items. The visit point is the 4th and 8th weeks after registration. In order to further elucidate the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis， the effective components of Osteoking and the relevant gene sets of non-steroidal anti-inflammatory drugs and knee osteoarthritis were obtained through network pharmacology methods and retrieval in bone injury cross database， TCMSP， and other databases. Venn analysis was performed on the relevant gene sets， and a PPI network diagram was constructed. Then key core targets were screened out， and enrichment GO and KEGG enrichment analyses were conducted. ResultThe VAS score of the observation group decreases by an average of （-2.79±1.206） scores in the 4th week， which is better than the control group ［（-2.73±1.575） scores， P<0.05］. The VAS score of the observation group decreases by an average of （-3.97±1.308） scores in the 8th week， which is better than the control group ［（-3.89±1.822） scores， P<0.05］. The total WOMAC score of the observation group decreases by an average of （-52.07±21.677） scores points in the 8th week， which is significantly better than the control group ［（-46.75±25.368） scores， P<0.05］. The observation group has an average decrease of （-10.99±4.229） scores in WOMAC （pain） score in the 8th week， which is better than the control group ［（-10.03±5.535） scores， P<0.05］. The observation group has an average decrease of （-1.49±2.901） in WOMAC （stiffness） score in the 4th week， which is better than the control group ［（-0.92±1.998） scores， P<0.05］， and the observation group has an average decrease of （-1.90±3.200） scores in WOMAC （stiffness） score in the 8th week， which is better than the control group ［（-1.26±2.230） scores， P<0.05］. The observation group shows an average decrease of （-39.17±16.562） scores in WOMAC （joint function） score in the 8th week， which is significantly better than the control group ［（-35.47±20.098） scores， P<0.05］. According to network pharmacology analysis， the core network target of Osteoking in treating knee osteoarthritis is manifested as regulating signal pathways such as signal transduction transcription activator 3（STAT3）， vascular endothelial growth factor A（VEGFA）， tumor necrosis factor （TNF） to regulate cell signaling， angiogenesis， chondrocyte proliferation and migration， and inflammatory cells， thereby inhibiting inflammatory reactions， reducing damage， and delaying the development of the disease. ConclusionAfter a 4-week and 8-week course of treatment for knee osteoarthritis with Osteoking combined with non-steroidal anti-inflammatory drugs， there is a significant therapeutic effect on relieving pain and joint stiffness and improving joint function. In network pharmacology， Osteoking is involved in regulating inflammatory factors， metabolic response-related biological processes， the proliferation and apoptosis of chondrocytes， etc. in the treatment of knee osteoarthritis， resulting in anti-inflammatory and analgesic effects and improving joint mobility and joint stiffness. Therefore， it is worthy of clinical promotion and application.
ABSTRACT
ObjectiveTo investigate the improvement of the efficacy of Osteoking in patients with knee osteoarthritis in the onset and remission stage and to systematically explore its potential intervention mechanism， so as to provide a certain reference for improving the clinical application value of Osteoking and guiding its clinical rational drug use. MethodThrough the real-world study of the treatment of knee osteoarthritis with Osteoking， the data was obtained and entered into the "Osteoking for the treatment of knee osteoarthritis case registration system"， and 105 patients with episodic and remission knee osteoarthritis from the outpatient or inpatient orthopedic department of 20 medical institutions， including the Third Affiliated Hospital of Beijing University of Chinese Medicine， Peking Union Medical College Hospital， Wangjing Hospital of the Chinese Academy of Chinese Medical Sciences and Hunan Aerospace Hospital， from May 1， 2020 to December 31， 2021， were selected in the system. It included 60 patients treated with Osteoking and joint injection， and 45 patients treated with joint injection alone. The WOMAC osteoarthritis index score， visual analogue （VAS） pain score， individual types of pain symptoms （cold pain， hot pain， tingling， dull pain， soreness） and other TCM symptoms were observed and compared between the two groups， and statistically analyzed. In order to further elucidate the potential molecular mechanism of Osteoking combined with joint injection in the treatment of knee osteoarthritis in the treatment of onset and remission， this study used the "Bone Injury Cross Database （http：//bone-xtrans.com/database，BX-Data）" to collect the gene set of knee osteoarthritis disease， the traditional Chinese medicinal materials， chemical composition， material base， candidate target， candidate target， sodium hyaluronate candidate target data for screening， and constructed an interaction network of "disease target". ResultsAmong the 105 patients with knee osteoarthritis enrolled， 15.24% （16/105） were in the episodic period， 84.76% （89/105） were in remission， and there were no convalescent patients. There were 72 cases （68.57%） in women， 33 cases （31.43%） more than men， 60 cases in the observation group and 45 cases in the control group in 105 patients. There were 20 patients with a VAS score of 5 and 19 patients with a score of 6 in the observation group， accounting for 65.00% of the observation group. The comparative results of VAS scores between groups before and after treatment showed that the scores of the two groups were （4.42±1.01） scores， （5.00±1.02） scores.4 weeks after treatment， and （3.12±1.04） scores and （3.56±1.08） scores，8 weeks after treatment， respectively， which were lower than those before treatment （6.23±1.28） scores，（ 6.02±1.22） scores （P<0.05）， and the comparative results of the pain properties of the two groups showed that the improvement rates before and after thermal pain and tingling in the observation group were 3.3%（2/60） and 16.7%（10/60）， respectively. The control group was 2.2% （1/45）and 15.6%（7/45）［（χ2=4.034、13.583，P<0.05）］， respectively， and the improvement rate of cold pain and soreness in the observation group was 5.0%（3/60） and 3.3%（2/60）， which was higher than that of the control group . The results of comparing the WOMAC scores before and after treatment of the two groups showed that the difference between the stiffness score before and after treatment in the observation group was （1.68±1.42） scores， the difference between the score before and after treatment in the control group was （1.20±1.60） scores （P<0.05）， and the pain score before and after treatment was （3.43±2.88） scores， the difference before and after daily activity score was （12.37±10.21） scores， and the total score before and after treatment was （17.48±12.76） scores， which were also higher than those in the control group （2.82±3.29）， （10.80±9.63），（14.82±12.62） scores. The results of comparing the improvement of other symptoms before and after treatment showed that the improvement rate of less sleep and more dreams in the observation group was 28.3%（17/60）， which was significantly higher than that of the control group of 2.2%（1/45）（χ2=5.914，P<0.05）， and the improvement rates of the five symptoms of thirst and drinking， irritability， dry mouth and pharynx， dull complexion and hand， foot and mouth fever in the observation group were 3.3%（2/60）， 10.0%（6/60）， 8.3%（5/60）， 10.0%（6/60） and 5.0%（3/60）， respectively， which were higher than those in the control group -2.2%（1/45）， 2.2%（1/45）， 2.2%（1/45）， 4.5%（2/45）， -6.7%（3/45）. Through network analysis， it was found that the enrichment pathway of Henggu bone wound healing agent mainly acted on the three mechanisms of bone improvement， energy metabolism and anti-inflammatory and analgesic， and the sodium hyaluronate enrichment pathway mainly acted on the anti-inflammatory and analgesic mechanism. ConclusionThe efficacy of Osteoking combined with intra-articular injection of sodium hyaluronate in the treatment of patients with knee osteoarthritis in attack and remission is better than that of sodium hyaluronate alone， especially in anti-inflammatory and analgesic， and the two drugs have synergistic effect. Osteoking may play its role in relieving the symptoms of joint stiffness， tingling， heat pain， and less sleep and more dreams by improving bone quality and regulating the body's energy metabolism pathways， which is worthy of clinical promotion.
ABSTRACT
Objective:To analyze the factors influencing pulmonary infections in elderly neurocritical patients in the intensive care unit (ICU) and to explore the predictive value of risk factors for pulmonary infections.Methods:The clinical data of 713 elderly neurocritical patients [age ≥ 65 years, Glasgow coma score (GCS) ≤ 12 points] admitted to the department of critical care medicine of the Affiliated Hospital of Guizhou Medical University from 1 January 2016 to 31 December 2019 were retrospectively analyzed. According to whether or not they had HAP, the elderly neurocritical patients were divided into hospital-acquired pneumonia (HAP) group and non-HAP group. The differences in baseline data, medication and treatment, and outcome indicators between the two groups were compared. Logistic regression analysis was used to analyze the factors influencing the occurrence of pulmonary infection.The receiver operator characteristic curve (ROC curve) was plotted for risk factors and a predictive model was constructed to evaluate the predictive value for pulmonary infection.Results:A total of 341 patients were enrolled in the analysis, including 164 non-HAP patients and 177 HAP patients. The incidence of HAP was 51.91%. According to univariate analysis, compared with the non-HAP group, mechanical ventilation time, the length of ICU stay and total hospitalization in the HAP group were significantly longer [mechanical ventilation time (hours): 171.00 (95.00, 273.00) vs. 60.17 (24.50, 120.75), the length of ICU stay (hours): 263.50 (160.00, 409.00) vs. 114.00 (77.05, 187.50), total hospitalization (days): 29.00 (13.50, 39.50) vs. 27.00 (11.00, 29.50), all P < 0.01], the proportion of open airway, diabetes, proton pump inhibitor (PPI), sedative, blood transfusion, glucocorticoids, and GCS ≤ 8 points were significantly increased than those in HAP group [open airway: 95.5% vs. 71.3%, diabetes: 42.9% vs. 21.3%, PPI: 76.3% vs. 63.4%, sedative: 93.8% vs. 78.7%, blood transfusion: 57.1% vs. 29.9%, glucocorticoids: 19.2% vs. 4.3%, GCS ≤ 8 points: 83.6% vs. 57.9%, all P < 0.05], prealbumin (PA) and lymphocyte count (LYM) decreased significantly [PA (g/L): 125.28±47.46 vs. 158.57±54.12, LYM (×10 9/L): 0.79 (0.52, 1.23) vs. 1.05 (0.66, 1.57), both P < 0.01]. Logistic regression analysis showed that open airway, diabetes, blood transfusion, glucocorticoids and GCS ≤ 8 points were independent risk factors for pulmonary infection in elderly neurocritical patients [open airway: odds ratio ( OR) = 6.522, 95% confidence interval (95% CI) was 2.369-17.961; diabetes: OR = 3.917, 95% CI was 2.099-7.309; blood transfusion: OR = 2.730, 95% CI was 1.526-4.883; glucocorticoids: OR = 6.609, 95% CI was 2.273-19.215; GCS ≤ 8 points: OR = 4.191, 95% CI was 2.198-7.991, all P < 0.01], and LYM, PA were the protective factors for pulmonary infection in elderly neurocritical patients (LYM: OR = 0.508, 95% CI was 0.345-0.748; PA: OR = 0.988, 95% CI was 0.982-0.994, both P < 0.01). ROC curve analysis showed that the area under the ROC curve (AUC) for predicting HAP using the above risk factors was 0.812 (95% CI was 0.767-0.857, P < 0.001), with a sensitivity of 72.3% and a specificity of 78.7%. Conclusions:Open airway, diabetes, glucocorticoids, blood transfusion, GCS ≤ 8 points are independent risk factors for pulmonary infection in elderly neurocritical patients. The prediction model constructed by the above mentioned risk factors has certain predictive value for the occurrence of pulmonary infection in elderly neurocritical patients.
ABSTRACT
Objective:To investigate the effects of educational level on smoking cessation in patients with moderate to severe tobacco dependence, explore effective individualized smoking cessation methods, and increase smoking cessation rate.Methods:A total of 480 patients with moderate to severe tobacco dependence who were willing to quit smoking and received treatment in the Department of Respiratory and Critical Care Medicine, Shengli Oilfield Central Hospital from January to December 2020 were included in this study. They were divided into four groups ( n = 120/group) according to their educational level: group A (elementary school and below), group B (junior high school and senior high school), group C (technical secondary school or college), and group D (university and above). All patients were randomly assigned to undergo "5A" intervention alone or "5A" intervention combined with varenicline intervention (combined intervention). Patients' awareness of the health risks of tobacco smoking was compared among the four groups. The smoking cessation rate measured at different time points was compared between different intervention strategies. Results:The scores of health risk of tobacco smoking in groups D, C, B, and A were (806.5 ± 35.7) points, (710.8 ± 26.2) points, (643.6 ± 43.4) points, and (512.4 ± 30.1) points, respectively. Patients with high education levels had high awareness of the health risk of tobacco smoking ( F = 1 543.26, P < 0.001). At 1, 3, and 6 months, the smoking cessation rate of combined intervention was higher than that of "5A" intervention alone in each group (group A: χ2 = 3.85, 4.23, 4.10, group B: χ2 = 4.30, 4.09, 4.60, group C: χ2 = 6.81, 4.30, 4.03, group D: χ2 = 6.71, 6.51, 4.73, all P < 0.05). The smoking cessation rate after 6 months of "5A" intervention alone or combined intervention in group D was 60.0% and 78.3% respectively, which were significantly higher than 41.7% and 60.0% in group C, 23.3% and 41.7% in group B, and 20.0% and 36.7% in group A ( χ2 = 26.59, 26.12, both P < 0.001). At different time points, the smoking cessation rates of the "5A" intervention alone in group D were significantly higher than those of combined intervention in groups A and B ( χ2 = 9.25, 25.04, 7.29, all P < 0.05). Conclusion:Awareness of the health risks of tobacco smoking is related to a patient's educational level, and affects smoking cessation. Individualized smoking cessation interventions based on a patient's educational level can increase the rate of smoking cessation.
ABSTRACT
Objective:To analyze the risk factors of prolonged mechanical ventilation (PMV) in patients with sepsis complicated by abdominal surgery, and to evaluate the predictive value of risk factors for PMV.Methods:A retrospective case-control study was conducted. The clinical data of patients with postoperative abdominal sepsis complicated with invasive mechanical ventilation who were admitted to the intensive care unit (ICU) of the Affiliated Hospital of Guizhou Medical University from January 1, 2018 to December 31, 2020 were collected. The patients were divided into PMV group (duration of mechanical ventilation longer than 48 hours) and non-PMV group (duration of mechanical ventilation shorter than 48 hours) according to the duration of mechanical ventilation in ICU. The patient's gender, age, body mass index (BMI), underlying diseases, mean arterial pressure (MAP), complete blood count, blood biochemistry, arterial blood gas, cardiac function indicators, procalcitonin (PCT) at admission to the ICU, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) and the sequential organ failure assessment (SOFA) scores in the first 24 hours of admission to the ICU, and other clinical information were recorded. Univariate and multivariate Logistic regression models were used to analyze the risk factors for PMV. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of related indicators for PMV.Results:A total of 195 patients with sepsis after abdominal surgery who received invasive mechanical ventilation were enrolled, including 127 males (65.1%) and 68 females (34.9%), with the median age of 65 (21, 93) years old. There were 91 patients (46.7%) in the non-PMV group and 104 patients (53.3%) in the PMV group. Univariate analysis showed that the APACHEⅡ score, SOFA score, cardiac troponin T (cTnT), N-terminal pro-B type natriuretic peptide (NT-proBNP) in the PMV group were significantly higher than those in the non-PMV group. Oxygenation index (PaO 2/FiO 2), total protein (TP) and prealbumin (PA) in the PMV group were all lower than those in the non-PMV group when admitted to ICU. In the PMV group, serum creatinine (SCr), blood urea nitrogen (BUN), cystatin C (Cys C) were significantly increased, prothrombin time (PT) was significantly prolonged, the proportion of patients with septic shock and hypertension were significantly increased as compared with those in the non-PMV group. Multivariate analysis showed that low PaO 2/FiO 2 at ICU admission [odds ratio ( OR) = 0.995, 95% confidence interval (95% CI) was 0.992-0.999, P = 0.010], high ln PCT ( OR = 1.301, 95% CI was 1.088-1.555, P = 0.004), high ln cTnT ( OR = 1.562, 95% CI was 1.079-2.261, P = 0.018) and septic shock ( OR = 4.967, 95% CI was 2.461-10.026, P = 0.000) were the independent risk factors for PMV in patients with sepsis after abdominal surgery. ROC curve analysis showed that the PaO 2/FiO 2, ln cTnT, ln PCT and septic shock had certain predictive value for PMV, the area under the ROC curve (AUC) of the four variables were 0.607, 0.638, 0.690 and 0.711, the sensitivity was 50.0%, 62.5%, 86.5% and 74.0%, and the specificity was 71.4%, 62.6%, 48.3% and 68.1%, respectively. The AUC for the joint prediction of the four variables was 0.803, with a sensitivity of 76.0% and a specificity of 78.0%. It suggested that the multivariate joint prediction of PMV was more accurate. Conclusions:Decreased PaO 2/FiO 2, increased PCT, increased cTnT and the occurrence of septic shock are independent risk factors for PMV in patients with sepsis complicated by abdominal surgery. The combination of above four indices was more accurate than one single variable in predicting PMV and had higher diagnostic value.
ABSTRACT
Objective:To investigate the risk factors that were associated with the death of elderly patients who were admitted to the intensive care unit (ICU) after elective abdominal surgery, and to find reliable and sensitive predictive indicators for early interventions and reducing the mortality.Methods:A retrospective case-control study was conducted. The clinical data of elderly (age≥65 years old) patients after elective abdominal surgery admitted to the ICU of the Affiliated Hospital of Guizhou Medical University from January 1st 2016 to December 31st 2020 were collected, including the patient's gender, age, body mass index (BMI), medical history, American Society of Anesthesiologists (ASA) grades, surgical classification, intraoperative blood loss, duration of operation, interval time between end of operation and admission to the ICU, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score and the worst laboratory examination results within 24 hours of ICU admission, the first blood gas analysis in ICU, the duration of invasive mechanical ventilation, and the length of ICU stay. Postoperative abdominal infection was evaluated by the pathogenic culture of peritoneal drainage fluid and clinical symptoms and signs. The patients were divided into death group and survival group based on clinical outcomes, and clinical data were compared between the two groups. Binary multivariate Logistic regression analysis was used to screen the risk factors of death, and the receiver operator characteristic curve (ROC curve) was plotted to analyze the predictive values of these risk factors.Results:A total of 226 elderly patients with elective abdominal surgery were admitted to the ICU of our hospital during the past 5 years, of whom, two patients who did not undergo laboratory examinations within 24 hours of admission to the ICU were excluded. Finally, 224 patients met the criteria, with 158 survivors and 66 deaths. Univariate analysis showed that: compared with survival group, APACHEⅡscore, blood lactate acid (Lac) and the proportion of postoperative abdominal infection were higher in death group [APACHEⅡ score: 27.5 (25.0, 31.3) vs. 23.0 (18.0, 27.0), Lac (mmol/L): 2.9 (1.8, 6.6) vs. 1.8 (1.1, 2.8), the proportion of postoperative abdominal infection: 65.2% (43/66) vs. 35.4% (56/158), all P < 0.01], prothrombin time (PT), activated partial thromboplastin time (APTT) and interval time between end of surgery and admission to ICU were longer [PT (s): 17.20 (14.50, 18.63) vs. 14.65 (13.90, 16.23), APTT (s): 45.15 (38.68, 55.15) vs. 39.45 (36.40, 45.70), interval time between end of surgery and admission to ICU (hours): 39.2 (0.7, 128.9) vs. 0.7 (0.3, 2.0), all P <0.01], postoperative hemoglobin (Hb), platelet count (PLT), prealbumin (PA), mean arterial pressure (MAP) and oxygenation index (PaO 2/FiO 2) were lower in death group [Hb (g/L): 95.79±23.64 vs. 105.58±19.82, PLT (×10 9/L): 138.5 (101.0, 177.5) vs. 160.5 (118.5, 232.3), PA (g/L): 80.88±43.63 vs. 116.54±50.80, MAP (mmHg, 1 mmHg = 0.133 kPa): 76.8±19.1 vs. 91.6±19.8, PaO 2/FiO 2 (mmHg): 180.0 (123.5, 242.5) vs. 223.5 (174.8, 310.0), all P < 0.05]. Binary multivariate Logistic regression analysis showed that APACHEⅡscore [odds ratio ( OR) = 1.187, 95% confidence interval (95% CI) =1.008-1.294, P < 0.001], interval time between end of operation and admission to ICU ( OR = 1.005, 95% CI = 1.001-1.009, P = 0.016) and postoperative abdominal infection ( OR = 2.630, 95% CI = 1.148-6.024, P = 0.022) were independent risk factors for prognosis in these patients. MAP ( OR = 0.978, 95% CI = 0.957-0.999, P = 0.041) and PaO 2/FiO 2 ( OR = 0.994, 95% CI = 0.990-0.998, P = 0.003) were protective factors for the patients' prognosis. Lac, Hb, PLT, PA, PT and APTT had no predictive value for the prognosis of elderly patients admitted to ICU after elective abdominal surgery [ OR value and 95% CI were 1.075 (0.945-1.223), 1.011 (0.99-1.032), 1.000 (0.995-1.005), 0.998 (0.989-1.007), 1.051 (0.927-1.192) and 1.003 (0.991-1.016), respectively, all P > 0.05. ROC curve analysis showed that APACHEⅡscore, interval time between end of operation and admission to the ICU and the postoperative abdominal infection had certain predictive values for the prognosis of elderly patients, the area under ROC curve (AUC) were 0.755, 0.732 and 0.649 respectively, all P < 0.001; When the cut-off of APACHEⅡscore and interval time between end of operation and admission to the ICU were 24.5 scores and 2.15 hours, the sensitivity were 78.8% and 66.7%, respectively, and the specificity were 62.0% and 76.6%, respectively. The combined predictive value of the three variables was the highest, which AUC was 0.846, the joint prediction probability was 0.27, the sensitivity was 83.3%, and the specificity was 75.3%. Conclusion:APACHEⅡscore, interval time between end of surgery and admission to ICU, and postoperative abdominal infection may be independent risk factors for the death of elderly patients who were admitted to the ICU after elective abdominal surgery, there would be far greater predictive values when the three variables were combined.
ABSTRACT
Objective:To explore the efficacy and safety of low- and medium-dose of glucocorticoids in adult patients with acute respiratory distress syndrome (ARDS) through Meta-analysis and trials sequential analysis (TSA).Methods:Databases associated with adult ARDS treatment with low- and medium-dose glucocorticoids both in English and in Chinese were searched from PubMed, Medline, China Biology Medicine (CBM), Cochrane Library, CNKI, Wanfang Data and VIP, of which the search duration was from the establishment of the database to December 2020. Low-dose glucocorticoids were defined as methylprednisolone ≤ 1 mg·kg -1·d -1, and medium dose glucocorticoids were defined as methylprednisolone ≤ 2 mg·kg -1·d -1. According to the Cochrane Collaboration bias risk assessment tool, the quality of the included literature was evaluated, and the data were extracted. Meta-analysis and TSA were used to evaluate the effects of low- and medium-dose glucocorticoids on the hospital mortality, intensive care unit (ICU) mortality, and mechanical ventilation free time in ICU for 28 days, PaO 2/FiO 2, and the occurrence of nosocomial infections and hyperglycemia. Results:A total of 996 patients in 7 literatures were finally included, including 515 patients in the low- and medium-dose glucocorticoid group (hormone group) and 481 patients in the conventional treatment group (control group). The research quality of 7 literatures was relatively high. The results of Meta-analysis and TSA showed that, compared with the control group, the hospital mortality in the hormone group was significantly decreased [relative risk ( RR) = 0.77, 95% confidence interval (95% CI) was 0.66-0.89, P = 0.000 6], and mechanical ventilation free time in ICU for 28 days was significantly prolonged [standardized mean difference ( SMD) = 0.50, 95% CI was 0.36-0.65, P < 0.000 1]. Although Meta-analysis showed that the ICU mortality of the hormone group was significantly lower than that of the control group ( RR = 0.61, 95% CI was 0.38-0.99, P = 0.04), the TSA results showed that the cumulative Z value crossed the traditional threshold, but did not cross the TSA cut-off value, and the sample size did not reach required information size (RIS, n = 3 252), needed more research to confirm. Although Meta-analysis showed that PaO 2/FiO 2 in the hormone group was significantly higher than that in the control group ( SMD = 0.78, 95% CI was 0.13-1.43, P = 0.02), TSA showed that the cumulative Z value did not pass the traditional and TSA cut-off values. More research was needed for verification. Meta-analysis also showed that there was no significant difference in the incidence of new infection ( RR = 0.93, 95% CI was 0.74-1.17, P = 0.54) and the incidence of hyperglycemia ( RR = 1.11, 95% CI was 1.00-1.23, P = 0.05) between the hormone group and the control group. Conclusion:low- and medium-dose of glucocorticoids therapy can reduce the hospital mortality of adult ARDS patients and shorten the mechanical ventilation duration in ICU for 28 days, and low- and medium-dose of glucocorticoids therapy does not increase the risk of infection and hyperglycemia.
ABSTRACT
Objective:To investigate the effect of NEMO binding domain peptide (NBDP) on lung inflammation and apoptosis in mice with acute respiratory distress syndrome (ARDS) and its mechanism.Methods:Thirty-six male BALB/c mice were divided into normal saline (NS) control group, ARDS model group, NBDP negative control group and 6, 12 and 18 μg NBDP pretreatment group by random number table method, with 6 mice in each group. ARDS mouse model was reproduced by aerosol inhalation lipopolysaccharide (LPS) 50 μL. An equivalent among of NS was inhaled in NS control group. The mice in NBDP negative control group were inhaled the materials similar to the non-functional NBDP 30 minutes before the aerosol inhalation LPS; 6, 12 and 18 μg of NBDP 50 μL were respectively inhaled in NBDP pretreatment groups. After inhalation of LPS for 6 hours, mice were sacrificed to get lung tissue and observe the degree of pathological injury and edema. Western blotting was used to detect the phosphorylation of nuclear factor-κB (NF-κB) pathway related proteins [NF-κB inhibitor (IκB) kinaseα/β(IKKα/β), IκBα and NF-κB p65; p-IKKα/β, p-IκBα, p-p65] and the expression of caspase-3 in lung tissue. The bronchoalveolar lavage fluid (BALF) was collected and the levels of inflammatory markers such as myeloperoxidase (MPO), interleukins (IL-1β, IL-8), and tumor necrosis factor-α (TNF-α) were detected by enzyme linked immunosorbent assay (ELISA).Results:ARDS model group had severe edema and hemorrhage, alveolar structure destruction, pulmonary hemorrhage and hyaline membrane formation etc. under light microscope, consistent with the pathological characteristics of ARDS lung tissue, suggesting that the ARDS model was successfully reproduced. ELISA showed that MPO, IL-1β, IL-8 and TNF-α levels of BALF in ARDS model group were obviously higher than those in NS control group. There were no significant differences in the above inflammatory indicators between NBDP negative control group and ARDS model group. The levels of MPO, IL-1β, IL-8 and TNF-α in NBDP pretreatment groups were significantly lower than those in ARDS model group in a dose-dependent manner, especially in 18 μg NBDP, the differences were statistically significant as compared with ARDS model group [MPO (ng/L): 393.32±19.35 vs. 985.87±101.50, IL-1β (ng/L): 43.05±5.11 vs. 97.68±10.88, IL-8 (ng/L): 84.64±2.32 vs. 204.00±17.37, TNF-α (ng/L): 229.13±17.03 vs. 546.73±62.72, all P < 0.05]. Western blotting showed that p-IKKα/β, p-IκBα, p-p65 and caspase-3 protein expressions in ARDS model group were significantly higher than those in NS control group. There was no significant difference in above NF-κB pathway and apoptosis-related protein expression between the NBDP negative control group and ARDS model group. The p-IKKα/β, p-IκBα, p-p65 and caspase-3 protein expression in NBDP pretreatment groups were significantly lower than those in ARDS model group in a dose-dependent manner, especially in 18 μg NBDP, the differences were statistically significant as compared with ARDS model group [p-IKKα/β protein (p-IKKα/β/β-actin): 0.15±0.02 vs. 0.42±0.04, p-IκBα protein (p-IκBα/β-actin): 0.10±0.01 vs. 0.93±0.30, p-p65 protein (p-p65/β-actin): 0.22±0.05 vs. 1.37±0.21, all P < 0.05]. Conclusion:NBDP can inhibit inflammatory response and apoptosis in ARDS lung tissue in a dose-dependent manner, and its mechanism is associated with interference NF-κB signaling pathway transduction.
ABSTRACT
Objective:To determine the effect of andrographolide (AD) on the expression of procoagulant and fibrinolytic inhibitory factors in rat type Ⅱ alveolar epithelial cells (AECⅡ) stimulated by lipopolysaccharide (LPS).Methods:The AECⅡ cells RLE-6TN in the logarithmic growth phase were divided into 5 groups: the normal control (NC) group, the LPS group, and the 6.25, 12.5, and 25 mg/L AD groups (AD 6.25 group, AD 12.5 group, AD 25 group). The NC group was cultured with RPMI 1640 conventional medium. In the LPS group, 5 mg/L LPS was added to the RPMI 1640 conventional medium for stimulation. Cells in the AD groups were treated with 6.25, 12.5, and 25 mg/L AD in advance for 1 hour and then given LPS to stimulate the culture. The cells and cell culture supernatant were collected 24 hours after LPS stimulation. The protein and mRNA expressions of tissue factor (TF), tissue factor pathway inhibitor (TFPI), and plasminogen activator inhibition-1 (PAI-1) in cells were detected by Western blotting and real-time fluorescent quantitative polymerase chain reaction (RT-qPCR). The levels of procollagen Ⅲ peptide (PⅢP), thrombin-antithrombin complex (TAT), antithrombin Ⅲ (AT-Ⅲ) and activated protein C (APC) in the cell supernatant were detected by enzyme linked immunosorbent assay (ELISA).Results:Compared with the NC group, the protein and mRNA expressions of TF and PAI-1 in the LPS group were significantly increased, and the protein and mRNA expressions of TFPI were significantly reduced. At the same time, the levels of PⅢP and TAT in the cell supernatant were significantly increased, the levels of AT-Ⅲ, APC were significantly reduced. Compared with the LPS group, the protein and mRNA expressions of TF and PAI-1 in AD 6.25 group, AD 12.5 group, AD 25 group were significantly reduced [TF/GAPDH: 0.86±0.08, 0.45±0.04, 0.44±0.04 vs. 1.32±0.10, TF mRNA (2 -ΔΔCt): 2.59±0.25, 2.27±0.05, 1.95±0.04 vs. 4.60±0.26, PAI-1/GAPDH: 2.11±0.07, 1.45±0.04, 0.86±0.09 vs. 2.56±0.09, PAI-1 mRNA (2 -ΔΔCt): 3.50±0.22, 2.23±0.29, 1.84±0.09 vs. 6.60±0.27, all P < 0.05], while the protein and mRNA expressions of TFPI were significantly increased [TFPI/GAPDH: 0.78±0.05, 0.81±0.03, 0.84±0.07 vs. 0.36±0.02, TFPI mRNA (2 -ΔΔCt): 0.46±0.09, 0.69±0.07, 0.91±0.08 vs. 0.44±0.06, all P < 0.05]. Also the levels of PⅢP and TAT in the cell supernatant were significantly reduced, and the levels of AT-Ⅲ and APC were significantly increased [PⅢP (μg/L): 13.59±0.23, 12.66±0.23, 10.59±0.30 vs. 15.82±0.29, TAT (ng/L): 211.57±6.41, 205.69±4.04, 200.56±9.85 vs. 288.67±9.84, AT-Ⅲ (μg/L): 102.95±3.86, 123.92±2.63, 128.67±1.67 vs. 92.93±3.36, APC (μg/L): 1 188.95±14.99, 1 366.12±39.93, 1 451.15±29.69 vs. 1 145.55±21.07, all P < 0.05]. With the increase of the dose of AD, the above-mentioned promotion and inhibition effects became more obvious. In the AD 25 group, TF, PAI-1 protein and mRNA expressions decreased, TFPI mRNA expression increased, PⅢP level in the supernatant decreased and AT-Ⅲ, APC levels increased compared with AD 6.25 group, the difference was statistically significant, and the decrease of PAI-1 protein expression and PⅢP level in the supernatant were also statistically significant compared with AD 12.5 group. Conclusions:Andrographolide in the dose range of 6.25-25 mg/L can dose-dependently inhibit the expression and secretion of procoagulant and fibrinolytic inhibitor-related factors in AECⅡ cells RLE-6TN stimulated by LPS, and promote the secretion of anticoagulant factors. 25 mg/L has the most obvious effect.
ABSTRACT
Objective:To observe the effects of berberine on procoagulant and fibrinolytic inhibitory factors produced by rat type Ⅱ alveolar epithelial cell (AECⅡ) induced by lipopolysaccharide (LPS).Methods:AECⅡ cells (RLE-6TN cells) were cultured in vitro, and the cells in logarithmic growth phase were collected. The cytotoxicity text of berberine was detected by cell counting kit-8 (CCK-8) to determine the drug concentration range according to inhibition concentration of half cells (IC 50). The RLE-6TN cells were divided into five groups, the cells in blank control group were cultured in DMEM; the cells in LPS group were stimulated with 5 mg/L LPS; and the cells in berberine pretreatment groups were pretreated with 20, 50 and 80 μmol/L berberine for 1 hour, and then were co-cultured with 5 mg/L LPS. The cells were collected after LPS induced for 24 hours. The protein and mRNA expression levels of tissue factor (TF), tissue factor pathway inhibitor (TFPI) and plasminogen activator inhibitor-1 (PAI-1) in the cells were detected by Western blotting and real-time fluorescence quantification reverse transcription-polymerase chain reaction (RT-qPCR). The levels of activated protein C (APC), precollagen Ⅲ peptide (PⅢP), thrombin-antithrombin complex (TAT) and antithrombin Ⅲ (ATⅢ) in the cell supernatant were measured by enzyme linked immunosorbent assay (ELISA). Results:According to the inhibition rate curve, the IC 50 of berberine on RLE-6TN cells was 81.16 μmol/L. Therefore, 20, 50 and 80 μmol/L were selected as the intervention concentration of berberine. Compared with the blank control group, the expression and secretion of procoagulant and fibrinolytic inhibitory factors were abnormal in RLE-6TN cells after LPS induced for 24 hours. The protein and mRNA expression levels of TF and PAI-1 in the LPS group were significantly increased, but the protein and mRNA expression levels of TFPI were significantly decreased. Meanwhile, the levels of APC and ATⅢ in the cell supernatant were significantly decreased, while the levels of PⅢP and TAT were significantly increased. After pretreatment with berberine, the abnormal expression and secretion of procoagulant and fibrinolytic inhibitory factors induced by LPS were corrected in a dose-dependent manner, especially in 80 μmol/L. Compared with the LPS group, the protein and mRNA expression levels of TF and PAI-1 in the berberine 80 μmol/L group were significantly decreased [TF protein (TF/GAPDH): 0.45±0.02 vs. 0.55±0.03, TF mRNA (2 -ΔΔCt): 0.39±0.08 vs. 1.48±0.11, PAI-1 protein (PAI-1/GAPDH): 0.37±0.02 vs. 0.64±0.04, PAI-1 mRNA (2 -ΔΔCt): 1.14±0.29 vs. 4.18±0.44, all P < 0.01] and those of TFPI were significantly increased [TFPI protein (TFPI/GAPDH): 0.53±0.02 vs. 0.45±0.02, TFPI mRNA (2 -ΔΔCt): 0.94±0.08 vs. 0.40±0.05, both P < 0.01]. Meanwhile, the levels of APC and ATⅢ in the cell supernatant were significantly increased [APC (μg/L): 1 358.5±26.0 vs. 994.2±23.1, ATⅢ (μg/L): 118.0±7.4 vs. 84.4±2.7, both P < 0.01], while those of PⅢP and TAT were significantly decreased [PⅢP (μg/L): 11.2±0.4 vs. 18.6±0.9, TAT (ng/L): 222.1±2.8 vs. 287.6±7.0, both P < 0.01]. Conclusions:Berberine could inhibit the LPS-induced expressions of procoagulant and fibrinolytic inhibitory factors in rat AECⅡ cells and promote the expressions of anticoagulant factors in a dose-dependent manner. Berberine may be a new therapeutic target for alveolar hypercoagulability and fibrinolysis inhibition in acute respiratory distress syndrome (ARDS).
ABSTRACT
Objective:To explore the effect of small dose of low molecular weight heparin on the prognosis of elderly patients with severe pneumonia using systematic evaluation method.Methods:Databases including Wanfang data, VIP, CNKI, SinoMed, PubMed, Embase and Cochrane Library were searched for randomized controlled trial (RCT) studies about the comparison of conventional therapy and low molecular weight heparin on prognosis of elderly patients with severe pneumonia from the time of database establishment to August 2019. The patients in conventional treatment group were treated by improving ventilation, anti-infection, eliminating phlegm, relieving asthma and maintaining homeostasis while those in low molecular weight heparin group were subcutaneously injected with low molecular weight heparin of 4 000 U, once a day for 7 days. The patients' main outcomes included the oxygenation index (PaO 2/FiO 2) after 7 days of treatment, duration of mechanical ventilation, mortality in hospital, and secondary outcomes included acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and coagulation function after 7 days of treatment, the length of intensive care unit (ICU) stay, and incidence of bleeding. Data extraction and quality evaluation were conducted. The Meta-analysis of included studies that met the quality standards was performed using RevMan 5.3 software. Funnel diagram analysis was used to analyze the parameters with no less than 10 studies enrolled. Results:A total of 14 RCT studies were enrolled involving 1 173 elderly patients with severe pneumonia, among whom 590 received low molecular weight heparin while the other 583 received conventional therapy. All the included studies were well designed and of high quality. The results of Meta-analysis showed that compared with conventional therapy, small dose of low molecular weight heparin significantly elevated PaO 2/FiO 2 after 7 days of treatment [mean difference ( MD) = 19.25, 95% confidence interval (95% CI) was 16.88 to 21.61, P < 0.000 01], shortened the duration of mechanical ventilation ( MD = -48.88, 95% CI was -67.42 to -30.33, P < 0.000 01), and decreased mortality in hospital [odds ratio ( OR) = 0.40, 95% CI was 0.22 to 0.73, P = 0.003] and APACHEⅡ score after 7 days of treatment ( MD = -3.38, 95% CI was -3.94 to -2.83, P < 0.000 01), and shortened the length of ICU stay ( MD = -4.51, 95% CI was -5.75 to -3.27, P < 0.000 01). There was no significant difference in the changes of coagulation parameters after 7 days of treatment or the incidence of bleeding between low molecular weight heparin group and conventional therapy group [7-day thrombin time (TT): MD = 0.57, 95% CI was -0.15 to 1.28, P = 0.12; 7-day prothrombin time (PT): MD = 0.32, 95% CI was -0.35 to 0.98, P = 0.35; 7-day fibrinogen (FIB): MD = -0.17, 95% CI was -0.45 to 0.10, P = 0.22; incidence of bleeding: OR = 0.86, 95% CI was 0.36 to 2.07, P = 0.74]. The funnel diagram showed that there was publication bias of included 10 studies about APACHEⅡ score after 7 days of treatment. Conclusion:Small dose of low molecular weight heparin can improve the prognosis of elderly patients with severe pneumonia and it has no obvious side-effect on coagulation function.

ABSTRACT
Objective To investigate the mechanism and clinical characteristics of rapid spontaneous resolution of acute subdural hematoma in children. Methods The clinical data of 9 children with rapid spontaneous resolution of acute subdural hematoma were retrospective analyzed. Results Subdural hematoma of three cases were completely dissolved within 8 h, while those of the other 6 cases were significantly reduced which were completely dissolved in 48-72 h. Conclusions Rapid spontaneous resolution of acute subdural hematoma in children is rare in clinical practice. The redistribution and dilution of hematoma and the anatomical characteristics of the children patient determine the possibility of hematoma dissipation. The conservative treatment can get a good prognosis.
ABSTRACT
OBJECTIVE:To provide reference for investigating the nutrition situation of the inpatients in departments of spinal surgery and minimally invasive spinal surgery and promoting the clinical rational use of nutritional support drugs. METHODS:Des-ignated continuous sampling was used to select the inpatients that fit the conditions in the departments of spinal surgery and mini-mally invasive spinal surgery in our hospital from Jan. to Dec. 2013,and the nutritional risk screening 2002 was used to investigate the patients’nutritional risk at admission and upon discharge,the nutritional support during hospitalization were recorded. RE-SULTS:In the 432 enrolled patients,the overall incidence of nutritional risk was 11.57% at admission,12.40% in spinal surgery and 10.44% in minimally invasive spinal surgery;and the overall incidence of nutritional risk was 19.44% upon discharge, 23.60% in spinal surgery,with statistical significance when compared with admission(P0.05). The nutritional support rate of 50 pa-tients with nutritional risk at admission was 88.00%,14.14% of 382 non-risk patients still received a redundant nutritional support. The 44 patients with nutritional risk who received nutritional support had the average calories intake of(9.84±8.10)kJ/(kg·d),in-cluding 10.16% lipids and 9.55% protein;all patients who received nutritional support found no patients with enteral nutrition sup-port. CONCLUSIONS:Inpatients in departments of spinal surgery and minimally invasive spinal surgery suffer a lower incidence of nutritional risk at admission,and a higher incidence of nutritional risk in the former one upon discharge. While some patients who received nutritional support show no indication,and administrations of nutritional support are still debatable,the use of drug is irrational.
ABSTRACT
BACKGROUND:The immature disc nucleus pulposus is composed of notochordal cels, but there is no notochordal cel in the mature human intervertebral disc, in which the notochordal cels are replaced by chondrocyte-like cels. It is very important to comprehend the disappearance of the notochordal cels; however, it is stil unknown at present. OBJECTIVE: To elaborate the feasibility of notochordal cels to maintain the proliferation and phenotype of chondrocyte-like cels and to induce the cartilage-like differentiation of bone marrow mesenchymal stem cels. METHODS: The first author used the computer to retrieve PubMed and Wanfang databases using the key words of “notochord cels; nucleus pulposus cels; identify” in English and Chinese, respectively. Totaly 9 896 relevant articles published from January 1999 to August 2015 were retrieved. Repetitive studies were excluded, and finaly 36 articles were in accordance with the inclusion criteria. RESULTS AND CONCLUSION:Now, the main functions of notochordal cels are to promote synthesis of extracelular matrix in the nucleus pulposus, induce directional differentiation of mesenchymal cels into nucleus pulposus cels or act as “seed cels” to form the nucleus pulposus cels. The presence and disappearance of notochordal cels is related to intervertebral disc degeneration. Cel apoptosis is involved in static compressionviadeath receptor signals, and then leads to intervertebral disc degeneration. fas ligand can mediate the reduction of notochordal cels, and hypoxia-inducible factor can induce spinal cord injury thereby triggering cel death and complete disappearance of nucleus pulposus. The measurement and verification of immune makers of notochordal cels, CK-8, CK-18 and galectin-3, can benefit to the identification and isolation of notochordal cels, and thereby help the studies on cel growth and differentiation, function and its mechanism of apoptosis.
ABSTRACT
Objective:To explore the effects of eight-week group positive psychotherapy intervention on de-pression associated self-efficacy and subjective well-being in female nursing students.Methods:Totally 74 female nursing students with mild to moderate depression [the score of Beck Depression Inventory (BDI-Ⅱ)was 14 to 28]were selected from three nursing colleges of Changsha.They were randomly divided into two groups,40 in the control group and 34 in the intervention group.Samples in the intervention group were given the eight-week group positive psychotherapy,while the control group was given nothing (the control group could receive the intervention when the intervention was proved to be effective or the control group needed treatments).The General Self-efficacy Scale(GSES)and Index of Well-being(IWB)were used to get the outcome of female nursing students'self-effica-cy,subjective well-being at baseline,the time after the intervention,3 month follow-up,6 month follow-up.Results:The interactive effect between group and time of self-efficacy,subjective well-being were statistically significant (Ps0.05).At the end of the intervention,3 month follow-up and 6 month follow-up,the GSES score and IWB score in the intervention group were higher than those in the control group (Ps <0.05).Conclusion:Eight-week group positive psychotherapy could improve self-efficacy and subjective well-being of female nursing students who have mild to moderate depressive symptom.This intervention also has a long-term effect.
