ABSTRACT

ObjectiveTo investigate the association between monocyte-to-high-density lipoprotein cholesterol ratio (MHR) and nonalcoholic fatty liver disease (NAFLD). MethodsA total of 208 patients who were admitted to Department of Gastroenterology, Zhongshan Hospital Affiliated to Dalian University, from January 2018 to October 2020 and were diagnosed with NAFLD by abdominal CT were enrolled as NAFLD group, and 210 healthy individuals were enrolled as control group. All subjects underwent routine blood test, biochemical examination, and abdominal CT examination, and serum MHR was calculated. In addition, according to abdominal CT findings, the patients with NAFLD were divided into mild NAFLD group with 148 patients and moderate-to-severe NAFLD group with 60 patients, and the variables such as white blood cell count (WBC) and MHR were compared between the three groups. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and a one-way analysis of variance was used for comparison between multiple groups; the Mann-Whitney U test was used for comparison of data with skewed distribution between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups. The fourfold table chi-square test was used for comparison of categorical data between two groups, and the R×C table chi-square test was used for comparison between three groups. A Spearman correlation analysis was used to investigate the correlation of MHR with metabolic markers and the severity of NAFLD. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of MHR in predicting NAFLD. ResultsCompared with the control group, the NAFLD group had significant increases in body weight (t=-10.573, P<0.001), body mass index (BMI) (t=-13.112, P<0.001), smoking history (Z=14.667, P<0.001), WBC (t=-7.359, P<0.001), monocytes (Z=-9.932, P<0001), low-density lipoprotein cholesterol (t=-3.394, P=0.001), triglyceride (TG) (Z=-11.737, P<0001), cholesterol (t=-2.985, P=0.003), fasting blood glucose (FBG) (Z=-7.827, P<0.001), alanine aminotransferase (ALT) (Z=-12.583, P<0.001), and aspartate aminotransferase (AST) (Z=-9.514, P<0.001) and a significant reduction in serum high-density lipoprotein cholesterol (HDL-C) (t=10.440, P<0.001); in addition, MHR level had gender differences, and male patients had a significantly higher level than female patients (P<0.001). Compared with the control group and the mild NAFLD group, the moderate-to-severe NAFLD group had a significant increase in serum MHR level (P<0.001). The correlation analysis showed that serum MHR level was negatively correlated with HDL-C (r=-0.565, P<0.001) and were positively correlated with smoking history, body weight, BMI, WBC, monocytes, TG, FBG, ALT, and AST (r=0.449, 0.482, 0.430, 0.478, 0.892, 0.333, 0.157, 0.386, and 0281, all P<0.01). At the same time, MHR level was positively correlated with the severity of NAFLD (r=0.629, P<0.001). The ROC curve showed that MHR had an area under the ROC curve of 0.846 (95% confidence interval: 0.810-0.882, P<0.001), with a sensitivity of 77.9% and a specificity of 74.3%. ConclusionSerum MHR level is associated with NAFLD and can be used as a predictive index for evaluating the progression of NAFLD.

ABSTRACT

Objective:To evaluate the safety and effectiveness of the accurate puncture during sacral neuromodulation (SNM) guided with 3D printing navigation template based on reconstruction techniques using fusing sacral CT and MRI images.Methods:Totally 42 patients operated with SNM were selected in Renji Hospital, School of Medicine, Shanghai Jiaotong University from July 2016 to August 2017. The patients were randomly divided into control group ( n=22) and experimental group ( n=20) using random number table. The conventional cross-positioning technique under X-ray was used for puncture during SNM in the control group. While in the experimental group, the sacral CT and MRI images were fused for reconstruction and design of the navigation template, printed by 3D technique for the puncture in SNM. The times of punctures, the average time for puncture operation, the time of intraoperative testing of the stimulator device, the minimum onset voltage of the stimulator, the X-ray radiation dose, postoperative curative effect (rate of secondary transformation) and the incidence rate of complications were compared between the two methods using independent-simple t test or χ 2 test. Results:Compared to control group, fewer times of punctures, shorter time needed for puncture operation, shorter time of intraoperative testing of the stimulator, smaller radiation dose and minimum effective voltage were found in the experimental group ( P<0.05). There were 15 and 16 patients who completed the secondary transformation in the control group and experimental group, and there was no significant difference between the two groups (χ2=0.757, P=0.384). There were 3 cases of complications in the control group, including 2 cases of infection and 1 case of bleeding, while no complications in the experimental group. Conclusions:CT and MRI images fusion reconstruction-guided 3D printing navigation template can help perform accurate and safe punctures in SNM. Compared to conventional puncture positioned under X-ray, it can effectively improve the puncture efficiency, and reduce the radiation dose in the operation.

ABSTRACT

Objective:To explore the factors related to functional recovery of the knee in patients with tibial plateau fracture complicated with intercondylar ridge fracture.Methods:Included in this retrospective study were 63 patients who had been treated at Emergency Center of Trauma, The Third Hospital of Hebei Medical University from January to June 2019 for tibial plateau fracture complicated with intercondylar ridge fracture. They were 43 males and 20 females, aged from 18 to 66 years (average, 43.9 years). According to our comprehensive classification of tibial plateau fractures, there were 27 simple ones (20 cases of type Ⅰ and 7 cases of type Ⅱ) and 36 complicated ones (16 cases of type Ⅲ, 17 cases of type Ⅳ, one of type Ⅴ and 2 cases of type Ⅵ). To screen out major influencing factors, a multiple linear regression model was used to analyze the 12 factors that might affect functional recovery of the knee by the Hospital for Special Surgery (HSS) scoring: age, gender, occupation, fracture type, way of medical payment, cause of injury, operation method, starting time for rehabilitation, postoperative brace installation, time from injury to operation, length of hospital stay, and presence or absence of a free intercondylar ridge fracture fragment.Results:The 63 patients were followed up for 6.0 to 7.1 months (average, 6.1 months). The HSS knee scores ranged from 45 to 100 points (average, 92.4 points). The HSS knee scores were significantly different between different fracture types ( P<0.05). The HSS scores were significantly higher for the patients without a free intercondylar ridge fracture fragment than for those with ( P<0.05). Multiple linear regression model analysis of the 5 variables with P<0.02 in the single factor analysis (age, fracture type, way of medical payment, hospital stay and presence or absence of a free intercondylar ridge fracture fragment) and HSS scores showed that only fracture type and presence or absence of a free intercondylar ridge fracture fragment had a significant impact on the knee function. Their regression equation was Y=125.591-7.790a-17.277b (Y indicates HSS score, a indicates fracture type and b indicates presence or absence of a free intercondylar ridge fracture fragment). Conclusions:The short-term prognosis for tibial plateau fractures of comprehensive types Ⅰ&Ⅱ (simple ones) may be better than that for tibial plateau fractures of comprehensive types Ⅲ, Ⅳ, Ⅴ&Ⅵ (complicated ones). For patients with a free intercondylar ridge fracture fragment on their lateral knee X-ray film, effective reduction and fixation is indicated but is not for those without.

ABSTRACT

Objective:To evaluate our self-designed easily-breaking compression bone bolt plus bone plate in the treatment of tibial plateau fracture.Methods:From July 2018 to December 2018, 12 patients with tibial plateau fracture were treated at Emergency Center of Trauma, The Third Hospital of Hebei Medical University using our self-designed easily-breaking compression bone bolt plus bone plate. They were 8 males and 4 females, aged from 20 to 65 years (average, 45.6 years), with 6 left sides and 6 right sides injured. According to Schatzker classification, there were one case of type I, 3 cases of type Ⅱ, 3 cases of type Ⅲ, 2 cases of type Ⅳ, one case of type Ⅴ and 2 cases of type Ⅵ. The width of tibial plateau was measured and compared before and after operation on X-ray films. Operation time, blood loss and fracture union time were recorded. Loss of reduction and postoperative complications were followed up. Knee function was evaluated at the final follow-up by Rasmussen scoring.Results:For this cohort, operation time averaged 54.6 min, blood loss 25 mL, and fracture union time 17.2 weeks. No nonunion or delayed union was observed. The postoperative width of tibial plateau was (78.9±7.2) mm, significantly narrower than the preoperative value [(87.4±6.1) mm] ( P < 0.05). No loss of reduction or surgical complications occurred postoperation. Deep venous thrombosis of the lower extremity developed in 2 patients but recovered after treatment. The Rasmussen scoring for knee joint function at the final follow-up yielded 9 excellent, 2 good and one poor. Conclusion:In treatment of tibial plateau fractures, our self-designed easily-breaking compression bone bolt plus bone plate can restore width of tibial plateau, compress fracture fragments tightly and allow for early exercise, leading to fine functional recovery of the knee joint.

ABSTRACT

Objective:To investigate the associations of articular depression depth (ADD) and tibial plateau widening (TPW) by pre-operative CT measurement with incidence of lateral meniscal tear in patients with Schatzker type Ⅱ tibial plateau fracture.Methods:Included in this retrospective study were 131 patients who had been admitted to Emergency Center of Trauma, The Third Hospital Affiliated to Hebei Medical University from January 2016 to January 2020 for Schatzker type Ⅱtibial plateau fractures. They were 88 males and 51 females, aged from 18 to 60 years (average, 41.5 years), with 74 right and 57 left sides injured. All patients were treated with closed reduction and internal fixation assisted by bidirectional traction. Arthroscopy was used to detect the status of lateral meniscus immediately after closed reduction and internal fixation of the fracture fragments. Furthermore, patients were divided into 2 groups according to the integrity of lateral meniscus: meniscal tear group ( n=70) and tear-free group ( n=61). The 2 groups were compared in terms of age, gender, body mass index(BMI), injury side, time interval from injury to surgery, TPW and ADD. The receiver operating curve (ROC) was drafted to calculate the cut-off values of TPW and ADD in complication of lateral meniscal tear in patients with Schatzker type Ⅱ tibial plateau fracture. Results:The overall incidence of lateral meniscal tear in this cohort was 53.4% (70/131). There was no statistically significant difference in terms of age, gender, injury side, BMI or time interval from injury to surgery between the 2 groups ( P>0.05); TPW and ADD were significantly higher in the meniscal tear group than in the tear-free group ( P<0.05). To predict lateral meniscal tear in patients with Schatzker type Ⅱtibial plateau fracture, the area under ROC was 0.656 (95% CI: 0.562 to 0.750, P=0.002) for TPW and 0.709 (95% CI: 0.619 to 0.800, P<0.001) for ADD, respectively; the cut-off values of TPW and ADD were 4.3 mm and 6.1 mm. Conclusion:TPW and ADD may be effective predictors for prediction of lateral meniscal tear in patients with Schatzker type Ⅱ tibial plateau fracture.

ABSTRACT

Objective:To investigate the protective effect of pine pollen on lipopolysaccharide (LPS)-induced learning and memory impairments in mice and the underlying mechanism.Methods:Sixty mice were randomly divided into four groups ( n = 15/group): normal control, model, low-dose pine pollen (500 mg/kg) and high-dose pine pollen (1 000 mg/kg). Mouse models of learning and memory impairment were established by lateral ventricle injection of LPS. The learning and memory abilities of mice were determined by the Morris water maze test. Superoxide dismutase (SOD) activity and glutathione (GSH) and malondialdehyde (MDA) levels in the hippocampus of mice were measured. Interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), dopamine (DA), and norepinephrine (NE) levels in the hippocampus were also determined. Results:The latency in the passive avoidance test in the model group was significantly shorter than that in the normal control group [(134.80 ± 33.89) s vs. (282.20 ± 17.43) s, t = 4.23, P < 0.01]. The number of errors in the model group was significantly higher than that in the normal control group [(4.00 ± 1.58) vs. (1.20 ± 1.30) times, t = 2.85, P < 0.01]. The latency in the passive avoidance test in the low-dose pine pollen (500 mg/kg) and high-dose pine pollen (1000 mg/kg) groups was significantly longer than that in the normal control group [(189.40 ± 27.21) s or (213.40 ± 21.26) s vs. (134.80 ± 33.89) s, t = 3.21, 4.38, all P < 0.05]. The number of errors in the low-dose pine pollen (500 mg/kg) and high-dose pine pollen (1 000 mg/kg) groups was significantly lower than that in the normal control group [(1.60 ± 1.44) times or (1.40 ± 1.44) times vs. (4.00 ± 1.58) times, t = 5.12, 6.42, both P < 0.05]. SOD activity and GSH, DA and NE levels in the hippocampus in the model group were significantly decreased compared with the normal control group [SOD: (7.59 ± 1.77) kU/g vs. (39.90 ± 6.37) kU/g; GSH: (3.49 ± 0.13) mmol/g vs. (6.37 ± 0.14) mmol/g; DA: (418.42 ± 2.57) ng/L vs. (586.37 ± 3.64) ng/L; NE: (187.20 ± 5.41) ng/L vs. (298.42 ± 2.32) ng/L, t = 3.67, 8.23, 2.23, 3.65, all P < 0.05]. MDA, IL-6 and TNF-α levels in the hippocampus in the normal control group were significantly higher than those in the model group [MDA: (8.79 ± 0.82) mmol/g vs. (2.62 ± 0.16) mmol/g, IL-6: (48.07 ± 5.56) ng/L vs. (18.76 ± 1.42) ng/L, TNF-α: (87.20 ± 4.31) ng/L vs. (22.42 ± 3.39) ng/L, t = 7.45, 2.67, 4.35, P < 0.05 or P < 0.01]. SOD activity, GSH, DA and NE levels in the hippocampus in the low-dose pine pollen (500 mg/kg) and high-dose pine pollen (1 000 mg/kg) groups were significantly higher than those in the model group [SOD: (18.80 ± 2.39) kU/g, (28.70 ± 2.36) kU/g vs. (7.59 ± 1.77) kU/g, GSH: (5.04 ± 0.36) mmol/g, (5.45 ± 0.17) mmol/g vs. (3.49 ± 0.13) mmol/g, DA: (488.37 ± 3.46) ng/L, (506.29 ± 5.72) ng/L vs. (418.42 ± 2.57) ng/L, NE: (225.65 ± 3.72) ng/L, (239.76 ± 5.58) ng/L vs. (187.20 ± 5.41) ng/L, t = 4.56 or 6.71, t = 4.65 or 5.32, t = 4.73 or 6.72, t = 3.84 or 5.63, P < 0.05 or P < 0.01]. MDA, IL-6 and TNF-α levels in the hippocampus in the low-dose pine pollen (500 mg/kg) and high-dose pine pollen (1 000 mg/kg) groups were significantly lower than those in the model group [MDA: (5.72 ± 0.47) mmol/g, (3.77 ± 0.23) mmol /g vs. (8.79 ± 0.82) mmol/g, IL-6: (28.42 ± 3.54) ng/L, (23.43 ± 5.62) ng/L vs. (48.07 ± 5.56) ng/L, TNF-α: (48.87 ± 4.82) ng/L, (39.65 ± 6.69) ng/L vs. (87.20 ± 4.31) ng/L, t = 6.31 or 7.28, t = 3.46 or 6.31, t = 4.28 or 3.57, P < 0.05 or P < 0.01]. Conclusion:Pine pollen can improve LPS-induced learning and memory impairments possibly through up-regulating the levels of monoamine neurotransmitters DA and NE and inhibiting the levels of oxidative stress and inflammatory reaction in the hippocampus of mice.

ABSTRACT

Objective:To make an empirical study on verifying whether the self-developed simple laparoscopic simulator can play a good role in the training of laparoscopic skills.Methods:Twenty-four Batch 2018 and Batch 2019 undergraduates of five-year clinical medicine of the Army Medical University were recruited in this study, and they were randomly divided into a research group and a control group for 4 weeks of simulation training, 3 times a week, 1 class hour each time. The training content was fundamental laparoscopic skills (FLSs). Before and after the training, the assessment was performed and the results and completion time were recorded. After the training, a satisfaction questionnaire was conducted among all trainees. SPSS 22.0 was used for data statistical analysis.Results:There was no statistical difference between the completion time and assessment results of the two groups before training ( P > 0.05). After four weeks of training, the completion time of the research group was shortened by 10.03% and the training performance increased by 35.17%; the completion time of the control group was shortened by 2.09%, and the training performance improved 12.34%. The comparison between groups found that the research group was superior than the control group, and the performance of the two groups were all improved after training. Most trainees recognized the simulator and were willing to promote it to other trainees according to the questionnaire feedback. Conclusion:The original laparoscopic simulator has a better training effect on simulation training than the traditional apprenticeship teaching has, which is of great significance for the promotion and optimization of laparoscopic skills teaching.

ABSTRACT

Objective:To better understand the clinical characteristics of children with pneumocystis pneumonia(PCP).Methods:Seven cases of non-human immunodeficiency virus infected children with PCP admitted to pediatric intensive care unit(PICU) at Xi′an Children′s Hospital from January 1, 2019 to December 31, 2019 were enrolled.Clinical findings, laboratory examination results, diagnosis, treatment, and outcome data were retrospectively reviewed.Results:There were seven children enrolled in this study including six boys and one girl.The average age was(6.09±3.80)years.Six patients received a long-term steroid or immunosuppressive therapy, and the average duration of medication was(80±30)days.One patient was eventually diagnosed with immunodeficiency disease despite no history of steroid and immunosuppressive therapy.Fever, cough and progressive dyspnea were the main manifestations.The pulmonary signs were not obvious, however, the chest radiographs showed serious ground glass changes.Laboratory examination showed that white blood cell counts were normal, lymphocyte counts were decreased to varying degrees, while C-reactive protein, calcitonin and lipopolysaccharide increased slightly or normal.Lactate dehydrogenase significantly increased and PaO 2/FiO 2 decreased, respectively.All children combined with different degrees of heart, liver and digestive tract damage.Pneumocystis jirovecii infection was diagnosed by metagenomics next-generation sequencing(mNGS), of which one case was detected by bronchoalveolar lavage fluid, and the remaining six cases were detected by peripheral blood.After entering PICU, mechanical ventilation, intravenous injection of human immunoglobulin, and continuous renal replacement therapy were performed.None of the children used TMP-SMZ for prophylaxis outside the hospital.Among them, one case was diagnosed with PCP before entering PICU and was given TMP-SMZ for 20 days, while the remaining six patients started to receive TMP-SMZ after entering PICU.Finally, one patient was cured, three died and another three cases died after giving up treatment.The average hospitalization days were(11.28±8.78)days, and the average hospitalization costs were (78, 000±24, 000) RMB. Conclusion:Children with non-human immunodeficiency virus infected PCP usually have underlying diseases or immunodeficiency diseases.Due to non-specific manifestations, rapid progression and high mortality, clinicians should pay more attention to it.It is necessary to dynamically observe the respiratory symptoms, perform mNGS as soon as possible, and give TMP-SMZ treatment in time.TMP-SMZ prophylaxis can be given to patients who are highly suspected of PCP but unable to perform pathogenic examinations.

ABSTRACT

Objective:To analyze the current status of frailty in elderly patients undergoing cardiac surgery, explore its risk factors, and establish a predictive model of frailty in order to provide targeted and predictive nursing programs.Methods:A total of 205 cardiac surgery patients admitted to the first affiliated hospital of Xinjiang Medical University from March 2015 to January 2019 were selected as the study subjects. Patients were divided into 2 groups according to whether they were frail: the frailty group ( n=78) and the control group ( n=127). Logistic regression was used to analyze the risk factors that affect the frailty of elderly patients undergoing cardiac surgery. The receiver operating characteristic curve (ROC) was used to evaluate the effectiveness of model X [consisting of body mass index (BMI), Mini-Mental State Examination (MMSE) score, number of diseased patients, and number of drugs] in diagnosing frailty in elderly patients undergoing cardiac surgery. Results:Of the 205 patients, 78 (38.05%) showed frailty. The proportion of high school education level and above, Tinetti Gaitassessment (TGA) score≥24 and MMSE score≥27 in the frailty group was lower than that in the control group, and the proportion of Geriatric Depression Scale-15 (GDS-15) score≥7, the number of diseases≥3 and the number of drugs≥5 in the frailty group was higher than that in the control group ( χ2 value was 9.254-26.061, P<0.05). Logistic regression analysis showed that BMI, MMSE score, number of diseased, and number of medications were independent risk factors for frailty in elderly patients undergoing cardiac surgery ( OR value was 0.032-5.275, P<0.05). The area under the ROC curve, sensitivity and specificity of frailty in elderly cardiac surgery patients assessed by model X were 0.913, 75.61% and 96.77%, respectively. Conclusion:The incidence of frailty is higher in elderly patients undergoing cardiac surgery. Model X can diagnose the frailty of elderly patients undergoing cardiac surgery and help clinical nurses to carry out targeted care.

ABSTRACT

OBJECTIVE@#To investigate the birth condition of preterm infants and the causes of preterm birth in Henan Province, China, and to provide a basis for the prevention and treatment of preterm birth.@*METHODS@#An epidemiological investigation was conducted for live-birth preterm infants who were born in 53 hospitals in 17 cities of Henan Province from January 1, 2019 to December 31, 2019 to investigate the incidence rate of preterm birth, the distribution of gestational age and birth weight, the use of antenatal glucocorticoids, and the causes of preterm birth.@*RESULTS@#The incidence rate of preterm birth was 5.84% (12 406/212 438) in the 53 hospitals. The proportions of preterm infants with gestational ages of < 28 weeks, 28 - < 32 weeks, 32 - < 34 weeks, and 34 - < 37 weeks were 1.58% (196/12 406), 11.46% (1 422/12 406), 15.18% (1 883/12 406), and 71.78% (8 905/12 406) respectively. The proportions of preterm infants with birth weights of < 1 000 g, 1 000- < 1 500 g, 1 500- < 2 500 g, 2 500- < 4 000 g, and ≥ 4 000 g were 1.95% (240/12 313), 8.54% (1 051/12 313), 49.53% (6 099/12 313), 39.59% (4 875/12 313), and 0.39% (48/12 313) respectively. The infants born by natural labor accounted for 28.76% (3 568/12 406), and those born by cesarean section accounted for 70.38% (8 731/12 406). The rate of use of antenatal glucocorticoids was 52.52% (6 293/11 983) for preterm infants and 68.69% (2 319/3 376) for the preterm infants with a gestational age of < 34 weeks. Iatrogenic preterm labor was the leading cause of preterm birth[40.06% (4 915/12 270)], followed by spontaneous preterm birth[30.16% (3 701/12 270)] and preterm birth due to premature rupture of membranes[29.78% (3 654/12 270)]. The top three causes of iatrogenic preterm birth were hypertensive disorders of pregnancy[47.12% (2 316/4 915)], fetal intrauterine distress[22.85% (1 123/4 915)], and placenta previa/placental abruption[18.07% (888/4 915)].@*CONCLUSIONS@#There is a relatively low incidence rate of preterm birth in Henan Province, and late preterm infants account for a relatively high proportion. Iatrogenic preterm birth is the main cause of preterm birth in Henan Province, and hypertensive disorders of pregnancy and fetal intrauterine distress are the main causes of iatrogenic preterm birth.

BACKGROUND@#Coronary atherosclerotic plaque could go through rapid progression and induce adverse cardiac events. This study aimed to evaluate the impacts of smoking status on clinical outcomes of coronary non-target lesions.@*METHODS@#Consecutive patients with coronary heart disease who underwent two serial coronary angiographies were included. All coronary non-target lesions were recorded at first coronary angiography and analyzed using quantitative coronary angiography at both procedures. Patients were grouped into non-smokers, quitters, and smokers according to their smoking status. Clinical outcomes including rapid lesion progression, lesion re-vascularization, and myocardial infarction were recorded at second coronary angiography. Multivariable Cox regression analysis was used to investigate the association between smoking status and clinical outcomes.@*RESULTS@#A total of 1255 patients and 1670 lesions were included. Smokers were younger and more likely to be male compared with non-smokers. Increase in percent diameter stenosis was significantly lower (2.7 [0.6, 7.1] % vs. 3.5 [0.9, 8.9]%) and 3.4 [1.1, 7.7]%, P = 0.020) in quitters than those in smokers and non-smokers. Quitters tended to have a decreased incidence of rapid lesions progression (15.8% [76/482] vs. 21.6% [74/342] and 20.6% [89/431], P = 0.062), lesion re-vascularization (13.1% [63/482] vs. 15.5% [53/432] and 15.5% [67/431], P = 0.448), lesion-related myocardial infarction (0.8% [4/482] vs. 2.6% [9/342] and 1.4% [6/431], P = 0.110) and all-cause myocardial infarction (1.9% [9/482] vs. 4.1% [14/342] and 2.3% [10/431], P = 0.128) compared with smokers and non-smokers. In multivariable analysis, smoking status was not an independent predictor for rapid lesion progression, lesion re-vascularization, and lesion-related myocardial infarction except that a higher risk of all-cause myocardial infarction was observed in smokers than non-smokers (hazards ratio: 3.00, 95% confidence interval: 1.04-8.62, P = 0.042).@*CONCLUSION@#Smoking cessation mitigates the increase in percent diameter stenosis of coronary non-target lesions, meanwhile, smokers are associated with increased risk for all-cause myocardial infarction compared with non-smokers.

ABSTRACT

OBJECTIVE@#To analyze the correlation of the minimal residual disease level with the prognosis of the AML patients with NPM1 gene mutation positive after chemotherapy.@*METHODS@#The clinical data of 112 newly diagnosed adult AML patients with positive NPM1 gene were collected and retrospectively analyzed. The correlation of the transcripts of NPM1 gene mutation with prognosis of patients was analyzed.@*RESULTS@#In 112 AML patients, the median transcript level of NPM1 gene mutation accounted for 83.68% (5.86%-486.57%), FLT3-ITD mutation positive was found in 44 cases (39.29%), chromosomal abnormalities in 22 cases (19.64%) and complete remission in 96 cases (85.71%). Multivariate logistic regression analysis showed that the initial induction therapy and white blood cell count closely related with complete remission (P<0.05). The median follow-up time was 22 (3-36) months, and the 3-year overall survival rate was 66.07% in 112 patients. Multivariate logistic regression analysis showed that both the high level of minimal residual disease at the initial complete remission and the high level of minimal residual disease after consolidation therapy were the independent risk factors for overall survival (P<0.05).@*CONCLUSION@#In newly diagnosed adult AML patients with NPM1 mutation positive, the early high level of minimal residual disease after chemotherapy closely relates with poor prognosis.

ABSTRACT

OBJECTIVE@#To investigate the inhibitory effect of adiponectin receptor agonist AdipoRon on proliferation of myeloma cell lines and its possible mechanism.@*METHODS@#The myeloma cell lines Sp2/0-Ag14 and MPC-11 were treated with different concentration of AdipoRon. The cell proliferation was detected by CCK-8. Western blot was used to determine the protein level of the signaling pathway. RT-PCR was used to quantify the mRNA copy number of adiponectin receptor AdipoR1 and AdipoR2 in the bone marrow cells from 21 patients with multiple myeloma (MM). Twenty-three normal bone marrow samples were served as control.@*RESULTS@#AdipoRon significantly inhibited the proliferation of MM cell lines Sp2/0-Ag14 and MPC-11 in a concentration-dependent and time-dependent manner. Western blot showed that AdipoRon induced an increase of the expression levels of apoptosis-related proteins cleaved caspase-3 and cleaved PARP. AdipoRon upregulated p-AMPK and its downstream p-ACC in MPC-11. In addition, AdipoRon upregulated LC3-II/LC3-I level and down-regulated the protein level of p62. The expression level of AdipoR1 in MM cells was significantly higher than that in normal controls, and the expression level of AdipoR2 in MM cells was significantly lower than that in normal controls.@*CONCLUSION@#Adiponectin receptors are expressed differentially between MM patients and normal subjects. AdipoRon, an adiponectin receptor agonist, can inhibit myeloma cell proliferation and induce apoptosis, and AMPK/autophagy pathway may be one of its mechanisms.

ABSTRACT

Objective@#To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) combined with donepezil on the cognition of persons with post-stroke cognitive impairment (PSCI) and their ability to perform activities of daily living (ADL).@*Methods@#A total of 106 PSCI patients were randomly divided into an observation group and a control group using a random number table. Those in the observation group received 10Hz rTMS (5 seconds on and 25 seconds off for 20 minutes daily) and donepezil daily, 5 days per week for 4 weeks, while those in the control group were provided with donepezil but only sham rTMS on the same schedule. Before and after 4 weeks of treatment, the Montreal cognitive assessment scale (MoCA), the Rivermead behavior memory test (RBMT) and the modified Barthel index (MBI) were used to evaluate the subjects′ cognitive functioning, memory capacity and ADL ability. The latency and amplitude of auditory event-related potential P300 were also assessed using a myoelectric evoked potential apparatus.@*Results@#After the treatment, improvement was observed in all the measurements of both groups. After the treatment, the average MoCA, RBMT and MBI scores, as well as the latency and amplitude of P300 in the observation group were all significantly better than among the control group.@*Conclusions@#rTMS can supplement donepezil′s ability to improve the cognition and ADL ability of persons with PSCI. Such therapy is worthy of clinical promotion and application.

ABSTRACT

Objectives@#To evaluate the distribution by age and sex of serum high-sensitivity C-reactive protein (hsCRP) in an urban Chinese population and to provide a profile prediction for the risk of bacterial infection, inflammatory diseases, or tissue damages in the body.@*Methods@#Serum hsCRP was determined using the Roche Tina-quant immuno-turbidimetric assay on a Hitachi 7600-010 automatic biochemical analyzer (Roche Diagnostics) in 1,572 males and 1,800 females, including 78 pregnant women, who were derived from the National Health and Nutrition Survey in 2010-2012.@*Results@#The average hsCRP concentration in urban China was 0.68 mg/L for males and 0.65 mg/L for females. Significant differences in hsCRP were found among different age groups ( < 0.05). Monitoring results showed no significant differences among the 6-11, 45-59, and ≥ 60-year-old groups in the comparison of hsCRP between males and females in large cities. However, hsCRP concentration was significantly higher in men aged 12-17 and 18-44 years than in women.@*Conclusion@#The distribution of the hsCRP status of residents in large cities in China was influenced by age and gender, and the hsCRP levels of both sexes increased gradually with age. In addition, hsCRP concentration was higher in healthy pregnant women than in non-pregnant women. Basing on our results, we recommend that this parameter be included in future national and international screening for early detection of various illnesses.

ABSTRACT

This article is based on basic data such as field surveys and literature surveys, contrasting and analyzing the distribution of Callicarpa nudiflora by different zoning methods, different data sources, and different spatial scales. The results showed that there were certain differences in the distribution results obtained by using different methods, such as qualitative description, similar ecological environment, and niche model, to divide the distribution of the C. nudiflora, but all of them could reflect the distribution of C. nudiflora to different degrees. Among them, the qualitative description division method has certain advantages in macro guidance in a large scale. The distribution range obtained by the ecological environment similar division method is wider than that obtained by applying the qualitative description method and the niche model method. The results of the zoning of the distribution of the C. nudiflora obtained from different data sources were different. The number and representativeness of the survey data have an impact on the zoning results. Through the analysis of the distribution of different spatial scales, the ecological factors and contribution rates that affect the distribution of C. nudiflora are different in China and in the world. The comprehensive multi-source data analysis showed that C. nudiflora mainly distributed in southern coastal provinces such as Hainan, Guangdong, Guangxi and Fujian in China, and also in Jiangxi, Guizhou, Yunnan, Sichuan, Chongqing, Hunan, Gansu, Taiwan and other provinces. Globally, C. nudiflora are suitable for distribution in Southeast Asia, such as China, Vietnam, Laos, Myanmar, India, etc. There are also potential distribution areas in the southern United States and Mexico.

ABSTRACT

In recent years, biosynthesis of triterpenoid saponins in medicinal plants has been widely studied because of their active ingredients with diverse pharmacological activities. Various oxidosqualene cyclases, cytochrome P450 monooxygenases, uridine diphosphate glucuronosyltransferases, and transcription factors related to triterpenoid saponins biosynthesis have been explored and identified. In the biosynthesis of triterpenoid saponins, the progress of gene mining by omics-based sequencing, gene screening, gene function verification, catalyzing mechanism of key enzymes and gene regulation are summarized and discussed. By the progress of the biosynthesis pathway of triterpenoid saponins, the large-scale production of some triterpenoid saponins and aglycones has been achieved through plant tissue culture, transgenic plants and engineered yeast cells. However, the complex biosynthetic pathway and structural diversity limit the biosynthesis of triterpenoid saponins in different system. Special focus can further be placed on the systematic botany information of medicinal plants obtained from omics large dataset, and triterpenoid saponins produced by synthetic biology strategies, gene mutations and gene editing technology.
