ABSTRACT

OBJECTIVE To explore the hotspots of aging adaptation of drug package inserts, and to provide evidence for the development of aging adaptation of drug package inserts in China. METHODS The relevant English literature on drug package inserts for the elderly published from 2012 to 2022 was retrieved from Web of Science Core Collection; bibliometric analysis was performed by using VOSviewer and CiteSpace software, to explore research hotspots in this field, and summarize obstacles and solutions for the development of this field. RESULTS & CONCLUSIONS This study collected a total of 335 literature related to the aging adaption of drug package inserts, from 819 research institutions in 51 countries (regions), involving 2 174 authors. The research development of drug package insert adaptation for the elderly has slowed down in the past decade, and developed countries such as the United States and Japan dominate this field. Authors such as Wolf from Northwestern University in the United States, have the largest number of publications(12 literature). The research focuses in this field include the risk management of medication for the elderly, the updating of medication information for the elderly in drug package inserts, and the understanding and compliance of the elderly with drug package inserts and their influencing factors. The solutions to related obstacles in the development of aging adaption in drug package inserts include improving the visibility and readability of drug package inserts, filling in the information on elderly medication in drug package inserts, and so on. China can learn from the experiences and methods of other countries, conduct investigations into the influencing factors of elderly package inserts and pharmacokinetic studies based on the characteristics of the Chinese population, and improve the safety of medication for elderly patients in multiple dimensions.

ABSTRACT

OBJECTIVE@#To study the protective effect of forsythiaside B (FB) against cerebral oxidative stress injury induced by cerebral ischemia/reperfusion (I/R) in mice and explore the underlying mechanism.@*METHODS@#Ninety C57BL/6 mice were randomized into sham-operated group, middle cerebral artery occlusion (MCAO) model group, and low-, medium and highdose (10, 20, and 40 mg/kg, respectively) FB groups. The expression levels of MDA, ROS, PCO, 8-OHdG, SOD, GSTα4, CAT and GPx in the brain tissue of the mice were detected using commercial kits, and those of AMPK, P-AMPK, DAF-16, FOXO3 and P-FOXO3 were detected with Western blotting. Compound C (CC), an AMPK inhibitor, was used to verify the role of the AMPK pathway in mediating the therapeutic effect of FB. In another 36 C57BL/6 mice randomized into 4 sham-operated group, MCAO model group, FB (40 mg/kg) treatment group, FB+CC (10 mg/kg) treatment group, TTC staining was used to examine the volume of cerebral infarcts, and the levels of ROS and SOD in the brain were detected; the changes in the protein expressions of AMPK, P-AMPK, DAF-16, FOXO3 and P-FOXO3 in the brain tissue were detected using Western blotting.@*RESULTS@#In mice with cerebral IR injury, treatment with FB significantly reduced the levels of ROS, MDA, PCO and 8-OHdG, increased the activities of antioxidant enzymes SOD, GSTα4, CAT and GPx, and enhanced phosphorylation of AMPK and FOXO3 and DAF-16 protein expression in the brain tissue (P < 0.01). Compared with FB treatment alone, the combined treatment with FB and CC significantly reduced phosphorylation of AMPK and FOXO3, lowered expression of DAF-16 and SOD activity, and increased cerebral infarction volume and ROS level in the brain tissue of the mice (P < 0.01).@*CONCLUSION@#FB inhibits oxidative stress injury caused by cerebral I/R in mice possibly by enhancing AMPK phosphorylation, promoting the downstream DAF-16 protein expression and FOXO3 phosphorylation, increasing the expression of antioxidant enzymes, and reducing ROS level in the brain tissue.

ABSTRACT

Purpose@#Loss-of-function mutations in the adenomatous polyposis coli (APC) gene are common in metastatic colorectal cancer (mCRC). However, the characteristic of APC specific mutations in mCRC is poorly understood. Here, we explored the clinical and molecular characteristics of N-terminal and C-terminal side APC mutations in Chinese patients with mCRC. @*Materials and Methods@#Hybrid capture-based next-generation sequencing was performed on tumor tissues from 275 mCRC pati-ents to detect mutations in 639 tumor-associated genes. The prognostic value and gene-pathway difference between APC specific mutations in mCRC patients were analyzed. @*Results@#APC mutations were highly clustered, accounting for 73% of all mCRC patients, and most of them were truncating mutations. The tumor mutation burden of the N-terminal side APC mutations group (n=76) was significantly lower than that of the C-terminal side group (n=123) (p < 0.001), further confirmed by the public database. Survival analysis showed that mCRC patients with N-terminus side APC mutations had longer overall survival than C-terminus side. Tumor gene pathway analysis showed that gene mutations in the RTK/RAS, Wnt and transforming growth factor β signaling pathways of the C-terminal group were significantly higher than those of the N-terminal group (p < 0.05). Additionally, KRAS, AMER1, TGFBR2, and ARID1A driver mutations were more common in patients with C-terminal side APC mutations. @*Conclusion@#APC specific mutations have potential function as mCRC prognostic biomarkers. There are obvious differences in the gene mutation patterns between the C-terminus and N-terminus APC mutations group, which may have certain guiding significance for the subsequent precise treatment of mCRC.

ABSTRACT

Objective:To explore the efficacy of digital and 3D printing technologies on design of superficial iliac circumflex artery flap for coverage the donor site of anterolateral thigh flap(ALTF).Methods:Clinical data of 8 patients were studied retrospectively for treatment of soft tissue defects of hand in the Department of Hand Surgery, Wuxi NO.9 People's Hospital Affiliated to Soochow University, from April 2017 to October 2021. The patients were 6 males and 2 females, aged from 29 to 59 years(mean, 45.8 years). Cause of injury: 3 patients were crushed, 2 by hot pressing, and 3 by machine strangulation. Site of injury included: 5 cases were dorsal hand defects and 3 cases were palm defects. All the wounds were contaminated to varying degrees with soft tissue defects. The areas of soft tissue defect ranged from 11 cm×10 cm to 22 cm×14 cm. Four patients had combined injuries of open fracture of metacarpals and phalanges and 3 with tendon defects. All wounds were repaired by free ALTF transplantation. And the donor sites in the thigh were repaired by superficial iliac circumflex artery flaps. The secondary wounds caused by flap harvesting on abdominal wall were closed directly. The targeted perforator vessels were detected preoperatively by CTA combined with CDU. 3D printed models of the affected hand were obtained before operation for individualised repairs according to the shape and area of the wounds. After the operation, all patients entered scheduled follow-ups at the outpatient clinic and via internet by observing the flap shape and testing the recovery of sensory and movement of adjacent joint.Results:The shapes and sizes of the wounds and the flaps were found basically in accordance with those in the preoperative simulative designs. All flaps in 8 patients survived and the wounds healed completely. All patients entered follow-ups for 8 to 24(average, 17.5) months. The donor thighs presented good appearance and colour, pliability without bloating. The range of motion of the hips and knees was not affected. Only linear scars remained in the abdominal donor sites, with natural colour and appearance.Conclusion:Digital and 3D printing technologies in preoperative design of flaps can help to locate the perforator vessels intraoperatively and guide the individualised design of the flaps with improved operation efficiency and satisfactory appearance of the flaps.

ABSTRACT

By reviewing the relevant literature of ancient herbal works and modern codices, this paper sorted out the historical evolution and developmental venation of processing of Notoginseng Radix et Rhizoma. On this basis, the modern research of processed products of Notoginseng Radix et Rhizoma was used as the breakthrough point to analyze the literature in terms of processing technology, chemical composition changes and changes in pharmacological effects before and after processing. According to the research status of processing of Notoginseng Radix et Rhizoma, some existing problems were analyzed in this paper, such as not many ancient processing methods used in modern time, lack of standardized research on processing technology. And saponins, polysaccharides, amino acids, flavonoids and other chemical components in Notoginseng Radix et Rhizoma may change to different degrees before and after processing, which was the main reason for the difference of efficacy before and after processing. However, the current research on the pharmacological effects of Notoginseng Radix et Rhizoma mainly focuses on raw products, resulting in a lack of in-depth research on the transformation mechanism of Notoginseng Radix et Rhizoma in processing difference, and the scientific connotation of "Shengxiao Shubu" has not been clearly elaborated, which is not conducive to the standardized clinical use of drugs. Therefore, it is necessary to further analyze the material basis of Notoginseng Radix et Rhizoma and its processed products, and to explore the change rule of chemical components before and after processing and its correlation with pharmacodynamic activity, so as to clarify the processing mechanism for providing scientific basis for its standardized processing, quality control and clinical rational use.

ABSTRACT

Objective:To investigate the influencing factors of anastomotic leakage after laparoscopic intersphincter resection (ISR) for extremely low rectal cancer and construction of nomogram prediction model.Methods:The retrospective case-control study was conducted. The clinicopathological data of 812 patients who underwent laparoscopic ISR for extremely low rectal cancer in the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital) from February 2012 to February 2022 were collected. There were 459 males and 353 females, aged (51±11)years. Observation indicators: (1) surgical situations; (2) follow-up; (3) influencing factors of postoperative anastomotic leakage; (4) construction and evaluation of nomogram prediction model for postoperative anastomotic leakage. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. The COX proportional hazard model was used for univariate and multivariate analyses. The R software(3.5.1 version) was used to construct nomogram prediction model. The receiver operating characteristic (ROC) curve was drawn and the area under curve (AUC) was used to evaluate the efficacy of the nomogram prediction model. The Bootstrap method was used for internal verification and to calculate the average consistency index (C-index). Results:(1) Surgical situations. All 812 patients underwent laparoscopic ISR for extremely low rectal cancer, including 388 cases undergoing partial ISR, 218 cases undergoing subtotal ISR and 206 cases undergoing complete ISR. All 812 patients underwent ileal protective ostomy, and there were 306 cases with double anastomosis and 203 cases with left colic artery preserved, respectively. The operation time and volume of intraoperative blood loss of 812 patients was (179±33)minutes and (33±13)mL, respectively. (2) Follow-up. All 812 patients were followed up for (13.5±0.9)months. Of the 812 patients, there were 62 cases with postoperative anastomotic leakage and the healing time of these cases was (33±6)days. (3) Influencing factors of postoperative anastomotic leakage. Results of multivariate analysis showed that male, neoadjuvant chemoradiotherapy, failure of reser-ving left colic artery were independent risk factors of anastomotic leakage after laparoscopic ISR for extremely low rectal cancer ( hazard ratio=5.98, 4.00, 16.26, 95% confidence interval as 1.66-24.12, 1.30-12.42, 3.00-90.89, P<0.05). (4) Construction and evaluation of nomogram prediction model for postoperative anastomotic leakage. According to the results of multivariate analysis, male, neoadju-vant chemoradiotherapy and failure of reserving left colic artery were used to construct the nomogram prediction model for anastomotic leakage after laparoscopic ISR for extremely low rectal cancer, and the score of these indexes in the nomogram prediction model was 50, 49, 93, respectively. The total score of these index corresponded to the incidence rate of anastomotic leakage. Results of ROC curve showed that the AUC of nomogram prediction model of anastomotic leakage after laparoscopic ISR for extremely low rectal cancer was 0.87 (95% confidence interval as 0.80-0.93, P<0.05), with sensi-tivity and specificity 0.96 and 0.60, respectively. Results of internal verification showed that the C-index of nomogram prediction model was 0.87. Conclusion:Male, neoadjuvant chemoradiotherapy, failure of reserving left colic artery are independent risk factors of anastomotic leakage after laparo-scopic ISR for extremely low rectal cancer, and the nomogram prediction model based on these indexes can predict the incidence rate of postoperative anastomotic leakage.

ABSTRACT

Objective:To investigate the correlation between serum albumin and hypoalbuminemia (HA) and the outcome after endovascular mechanical thrombectomy (EMT) in patients with stroke caused by acute anterior circulation large vessel occlusion.Methods:Stroke patients caused by acute anterior circulation large vessel occlusion received EMT treatment at the Department of Emergency Stroke, the Affiliated Hospital of Jining Medical University from June 2020 to August 2022 were retrospectively included. The demographic information, baseline clinical data, endovascular treatment parameters, and clinical outcomes of the patients were collected. HA was defined as serum albumin <35 g/L within 24 h of admission, and poor outcome was defined as the modified Rankin Scale score >2 at 90 d after onset. Multivariate logistic regression analysis was used to identify the independent influencing factors for poor outcomes. Results:A total of 177 patients were included, with a median age of 66 years, and 126 (71.19%) were males. Thirty-nine patients (22.03%) had HA, and 119 (67.23%) had poor outcomes. The proportion of pulmonary infection in the HA group was significantly higher than that in the non-HA group ( P<0.05). Multivariate logistic regression analysis showed that lower serum albumin (odds ratio [ OR] 4.102, 95% confidence interval [ CI] 1.316-16.451; P=0.028), postprocedural neurological deterioration ( OR 6.326, 95% CI 1.263-48.318; P=0.042) and pulmonary infection ( OR 5.873, 95% CI 1.028-24.452; P=0.018) were significantly independently associated with the poor outcomes. Conclusions:The HA group has a higher incidence of postprocedural pulmonary infection. Lower serum albumin, postprocedural neurological deterioration and pulmonary infection are the independent risk factors for the poor outcomes in patients with anterior circulation ischemic stroke who had successful recanalization after EMT.

ABSTRACT

ObjectiveTo explore the amelioration of cognitive dysfunction in diabetes mellitus (DM) by Jianpi Qinghua prescription (JPQH) based on type 2 diabetes (T2DM) model rats. MethodFifty healthy male Wistar rats of SPF grade were randomly divided into control group (n=10) and experimental group (n=40). The rats in the control group were fed conventionally, while those in the experimental group were fed on a high-sugar, high-fat diet for six weeks and administered with streptozotocin (STZ) for the induction of the DM model. The model rats were randomly divided into model group, sitagliptin group (1.2 g·L-1), pioglitazone group (0.8 g·L-1), and JPQH group (1.3 g·mL-1), with 10 rats in each group. After six weeks of drug intervention, the changes in body weight, blood glucose, and other related indexes of each group were recorded. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the peripheral blood and brain. The Morris water maze test was used to evaluate the cognitive function in rats. Hematoxylin-eosin (HE) staining was used to observe the pathological morphology of the hippocampal CA region. The amyloid β-protein 40 (Aβ40) level was detected by immunohistochemistry. The protein expression of t-tau and p-tau in hippocampal neurons of rats was detected by Western blot. ResultCompared with blank group, the body weight of model group was significantly decreased (P<0.05), blood glucose level was significantly increased (P<0.01), inflammatory cytokines TNF-α and IL-1β were increased (P<0.05), learning and spatial ability were significantly decreased (P<0.01), the arrangement of hippocampal cells was loose and disordered, and the intercellular space was significantly increased. The number of cells decreased significantly, and the expression of Aβ40 increased significantly. and increased t-tau and p-tau protein content in the hippocampus (P<0.01). Compared with model group, the JPQH group showed reduced blood glucose (P<0.01), decreased TNF-α and IL-1β levels in the peripheral blood and cerebrospinal fluid (P<0.05), a downward trend of IL-6 without a statistical difference, improved learning and spatial memory ability (P<0.01), densely arranged cells in the hippocampal CA1 area, increased cell number, reduced Aβ40 expression, and decreased p-tau protein expression (P<0.05). ConclusionJPQH can prevent cognitive dysfunction in DM by reducing inflammatory factor levels, decreasing neurotoxicity caused by Aβ40 deposition, and inhibiting hyperphosphorylation of tau protein in DM rats.

ABSTRACT

OBJECTIVE To evaluat e the cost-effectiveness of Keluoxin capsule combi ned with chemical medicine in the treatment of diabetic kidney disease (DKD)from the perspective of the whole society. METHODS Six-state Markov model with 1 year cycle and 40 years time horizon was constructed by means of secondary literature review ,medical record analysis of sample hospital and clinical expert consultation. The cost-effectiveness of Keluoxin capsule combined with chemical medicine versus chemical medicine alone for DKD was evaluated by taking the quality-adjusted life year (QALY)as the output index ,setting the discount rate as 5%,and taking one time domestic gross domestic product (GDP)per capita in 2020 of China as the judgement threshold of incremental cost-effectiveness ratio (ICER). RESULTS Within 40 years,Keluoxin capsule combined with chemical medicine group spent 8 644.09 yuan per capita more than chemical medicine alone group ,and gained more 0.143 QALYs;ICER was 60 460.25 yuan/QALY,which was less than one times GDP per capita of China in 2020(72 447 yuan). The results of sensitivity analysis showed that the annual days of using Keluoxin capsule ,the health utility value of DKD at early stage had a great influence on the results of cost-effectiveness analysis. The results of probabilistic sensitivity analysis suggested that the basic analysis results of this study were robust. CONCLUSIONS At the current price level ,Keluoxin capsule combined with chemical medicine is more cost-effective to treat DKD than chemical medicine alone. The dosage of Keluoxin capsule and health utility value should be paid attention in specific decision- bjmu.edu.cn making scenarios.

ABSTRACT

OBJECTIVE@#To assess the efficacy and safety of mulberry twig alkaloids (Sangzhi alkaloids, SZ-A) for treatment of type 2 diabetes in a randomized, double-blind, placebo-controlled multicenter clinical trial.@*METHODS@#A total of 200 patients were randomized to receive SZ-A (n=100) or placebo (n=100) for 16 weeks. The data analysis system for electronic data capture clinical trial central randomization system was used for randomization and dispensing of drugs. The primary outcome was the change in glycosylated hemoglobin (HbA1c) level. The secondary outcome included the proportions of cases with HbA1c <7.0% and HbA1c <6.5%, fasting blood glucose (FBG), postprandial blood glucose (PBG), area under curve for the PBG (AUC0-2h), body weight, and body mass index (BMI). Adverse events (AEs), severe adverse events (SAEs), treatment-related adverse events (TAEs), gastrointestinal disorders (GDs), blood pressure, routine blood tests, and liver and kidney function were monitored.@*RESULTS@#Compared with baseline, the change of HbA1c at week 16 was -0.80% (95% CI: -0.98% to -0.62%) and -0.09% (95% CI: -0.27% to 0.09%) in SZ-A group and placebo group, respectively. The proportion of patients with HbA1c <7% and <6.5% was higher in the SZ-A group than in the placebo group (46.8% vs. 21.6% and 29.9% vs. 10.8%). The observed values and changes in FBG, 1 h-PBG, 2 h-PBG, and AUC0-2h differed significantly between groups (P<0.001), but differences were not significant in body weight and BMI (P>0.05). The incidence rates of AEs, TAEs, and GDs differed significantly between groups (P=0.010, P=0.005, and P=0.006, respectively), whereas the incidence rates of SAEs showed no significant differences between groups (P=1.000).@*CONCLUSION@#SZ-A are effective and safe for treatment of type 2 diabetes. The protocol was registered in http://www.chictr.org.cn/showproj.aspx?proj=60117 (ChiCTR2000038550).

ABSTRACT

Objective: To compare the effects of preoperative neoadjuvant chemotherapy and postoperative adjuvant chemotherapy on the long-term survival of patients with radical resection for esophageal squamous cell carcinoma. Methods: Totally 1 082 patients with stage T3-4aN0-3M0 thoracic esophageal squamous cell carcinoma were recruited in this study who underwent radical resection at Department of Thoracic Surgery, Fourth Hospital, Hebei Medical University from January 2005 to January 2015. There were 798 males and 284 females, with a median age of 61 years (range: 37 to 86 years). There were 138 patients undergoing preoperative neoadjuvant chemotherapy, 392 patients postoperative adjuvant chemotherapy, and 552 patients surgery alone. The neoadjuvant chemotherapy group was used as the benchmark group to match the propensity score with the adjuvant chemotherapy group and the surgery-only group respectively at a ratio of 1∶3. A total of 7 covariates including tumor location, number of positive lymph nodes, tumor invasion depth, tumor differentiation degree, surgical procedure, vascular tumor thrombus and nerve invasion were included, and the caliper value was taken as 0.1. After matching, a total of 699 patients were included for the analysis, including 128 patients in the neoadjuvant chemotherapy group, 267 patients in the adjuvant chemotherapy group, and 304 patients in the surgery alone group. The Kaplan-Meier method was used to generate the survival curves which was tested by the Log-rank method for survival analysis. Results: After matching analysis, the 5-year overall survival rate was 41.5% in the neoadjuvant chemotherapy group with a median overall survival time of 43 months (95%CI: 27 to 59 months), 57.6% in the adjuvant chemotherapy group with a median overall survival time unreached, and 24.9% in the surgery alone group with a median overall survival time of 28 months (95%CI: 25 to 31 months) (χ²=60.475, P<0.01). For overall survival after matching, the adjuvant chemotherapy group was better than the neoadjuvant chemotherapy group (χ²=11.384, P=0.001), the neoadjuvant chemotherapy group was better than the surgery alone group (χ²=8.654, P=0.003), and the adjuvant chemotherapy group was better than surgery alone group (χ²=60.234, P<0.01). Conclusion: Both preoperative neoadjuvant chemotherapy and postoperative adjuvant chemotherapy can improve the long-term survival of patients with locally advanced esophageal squamous cell carcinoma undergoing radical resection, and the improvement effect of postoperative adjuvant chemotherapy is more obvious.

ABSTRACT

Objective:To automatically synthesize Al 18F-1, 4, 7-triazacyclononane-1, 4, 7-triacetic acid (NOTA)-fibroblast activation protein inhibitor (FAPI)-04, perform PET/CT imaging in vivo, and evaluate its diagnostic efficacy on tumors. Methods:Al 18F-NOTA-FAPI-04 was produced in All-in-one automatic synthesis module and its quality control was conducted by high performance liquid chromatography (HPLC) equipped with a radioactive detector. Al 18F-NOTA-FAPI-04 PET/CT imaging was performed in normal BALB/c mice ( n=3) and 4T1 breast cancer models ( n=3) to determine its biodistribution. Then Al 18F-NOTA-FAPI-04 and 18F-FDG PET/CT imaging were performed in a hepatocellular carcinoma patient (male, 51 years old). Results:The synthesis time of Al 18F-NOTA-FAPI-04 was about 35 min, and the radiochemical yield was (25.2±1.9)% (attenuation correction, n=3). The product was colorless transparent solution with pH value of 7.0-7.5, and the specific activity was (46.11±3.07) GBq/μmol (attenuation correction, n=3). The radiochemical purity was above 99.0% and was still above 98.0% at room temperature after 6 h. PET/CT imaging in mice showed that physiological uptake of Al 18F-NOTA-FAPI-04 was mainly in biliary system and bladder, and Al 18F-NOTA-FAPI-04 highly concentrated in tumor xenografts. PET/CT imaging in the patient showed that Al 18F-NOTA-FAPI-04 obtained high tumor background ratio (TBR) values of 4.1, 8.9, 5.4, 4.8, 2.2 in parasternal lymph nodes, anterior diaphragmatic lymph nodes, hilar lymph nodes, pancreaticoduodenal ligament lymph nodes, abdominal aortic lymph nodes, respectively, while TBR values were 1.0, 2.8, 5.0, 2.1, 1.1 by 18F-FDG. Conclusions:Al 18F-NOTA-FAPI-04 can be synthesized with short time, high radiochemical yield and good stability using All-in-one module. Al 18F-NOTA-FAPI-04 PET/CT imaging has high contrast and excellent diagnostic efficacy on tumors.

ABSTRACT

Objective:To analyze the effect of transitional care model (TCM) mode combined with resistance breathing training on hypoxic reactivity of respiratory center in elderly obese obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods:Totally 78 patients with OSAHS who met the criteria were selected from the geriatric department of Nanjing Drum Tower Hospital from January 2018 to December 2020 and divided into observation group and control group by random digits table method, with 39 cases in each group; the control group was intervened by basic nursing combined with resistance breathing training mode, and the observation group was intervened by TCM mode on the basis of the control group. Before nursing and 1 month after discharge, Pittsburgh Sleep Quality Index (PSQI), Short-Form 36-item Health Survey (SF-36), Montreal Cognitive Assessment (MoCA) were used to evaluate the sleep quality, quality of life and cognitive function of the patients. Besides, FVC, FEV 1, FEV 1/FVC were also tested before nursing and 1 month after discharge. Results:One month after discharge, the daytime dysfunction, use of sleep drugs, habitual sleep efficiency, subjective sleep quality, sleep disorder, sleep latency, sleep duration and total score of PSQI in the observation group were significantly lower than those in the control group (the control group: 2.27 ± 0.34, 2.03 ± 0.31, 2.09 ± 0.23, 1.85 ± 0.28, 2.11 ± 0.28, 1.40 ± 0.24, 2.12 ± 0.41, 13.87 ± 0.56; the observation group: 1.63 ± 0.33, 1.22 ± 0.29, 1.63 ± 0.29, 1.12 ± 0.31, 1.35 ± 0.34, 1.09 ± 0.28, 1.74 ± 0.26, 9.78 ± 0.59) ( t values were 4.91-31.61, all P<0.01). One month after discharge, the scores of mental health, physical pain, physiological function, physiological function, emotional function, life vitality, social function and overall health of SF-36 in the observation group were significantly higher than those in the control group (the control group: 62.83 ± 6.31, 68.94 ± 5.91, 61.99 ± 5.98, 64.85 ± 6.13, 43.28 ± 5.74, 64.85 ± 6.12, 61.21 ± 5.74, 62.31 ± 6.85; the observation group: 69.81 ± 5.74, 76.12 ± 6.02, 70.84 ± 6.08, 71.74 ± 5.99, 50.93 ± 6.12, 70.52 ± 5.94, 69.89 ± 5.53, 68.41 ± 4.99)( t values were 4.18-7.77, all P<0.01). One month after discharge, the scores of visual space and executive function, attention, language, delayed recall, orientation, abstraction and total score of MoCA in the observation group were significantly higher than those in the control group (the control group: 4.48 ± 0.37, 5.23 ± 0.29, 2.43 ± 0.27, 3.37 ± 0.31, 5.01 ± 0.33, 5.27 ± 0.26, 25.79 ± 1.17; the observation group:4.95 ± 0.31, 5.68 ± 0.27, 2.67 ± 0.24, 3.98 ± 0.19, 5.47 ± 0.28, 5.64 ± 0.23, 28.39 ± 1.09)( t values were 4.17-10.51, all P<0.01). One month after discharge, the levels of FVC, FEV 1 and FEV 1/FVC in the observation group were significantly higher than those in the control group, the control group: (2.59 ± 0.18) L, (1.60 ± 0.14) L, (61.78 ± 4.01)%; the observation group: (2.89 ± 0.19) L, (1.99 ± 0.17) L, (68.86 ± 3.99)% ( t = 7.21, 11.14, 7.87, all P<0.05).

ABSTRACT

Objective:Based on the degradation of skeletal muscle protein MuRF mediated by pFoxO1 when insulin resistance occurs, this paper explores the content change of skeletal muscle protein and the effect of Jianpi Qinghua formula when insulin resistance occurs.Methods:C57 mice were fed with high-fat food and made as the model of obesity accompanied by insulin resistance. Then they were divided into model group, Jianpi Qinghua formula group and metformin group according to random number table method with 10 mice in each group. Jianpi Qinghua formula group was orally administered with water decoction 20.961 g/kg, and the metformin group was orally administered with metformin suspension 18.498 g/kg, once a day for 12 consecutive weeks. Intraperitoneal Glucose Tolerance Tests (IPGTT) was used after the model was established and intervened respectively. The relative protein content of pFoxO1, FoxO1, MuRF, MyoD and myosin were detected by Western blot method, and the localization of MyoD and myosin was detected by immuno-histochemistry.Results:Compared with the model group, the blood glucose of IPGTT at 0 min, 60 min and 120 min of both Jianpi Qinghua formula group and Metformin group decreased ( P<0.05). Compared with model group, the ratio of pFoxO1/FoxO1 protein expression level (0.27±0.07, 0.24±0.14 vs. 0.05±0.03) of both Jianpi Qinghua formula group and Metformin group increased ( P<0.05), and the relative expression of MuRF protein (1.22±0.42, 1.15±0.32 vs. 3.21±0.35) of both Jianpi Qinghua formula group and Metformin group decreased ( P<0.05). The relative protein expression of MyoD (1.42±0.45 vs. 0.40±0.11) and myosin (0.80±0.11 vs. 0.51±0.08) relative protein expression of Jianpi Qinghua formula group was significantly higher than that of model group ( P<0.05). Immunohistochemical staining showed that MyoD (5.06±1.72 vs.2.28±0.83) and myosin (60.28±7.47 vs. 39.77±3.34) of Jianpi Qinghua formula group significantly increased compared with model group ( P<0.05). Conclusion:Jianpi Qinghua formula could effectively increase the content of skeletal muscle protein, enhancing the phosphorylation of FoxO1 in skeletal muscle and the inhibition of MuRF degradation pathway.

ABSTRACT

Objective:To investigate the characteristics of complications after internal fixation with hallo nails for femoral neck fractures according to OTA/AO classification and analyze the reasons for differences in complications of different classifications based on the current theories and lever-fulcrum balance theory.Methods:A retrospective case series analysis was made on clinical data of 113 patients with femoral neck fractures treated in Peking University People's Hospital from January 2014 to June 2020. There were 49 males and 64 females, with the age of 21-89 years [61(52, 72)years]. According to OTA/AO classification, there were 5 patients with type B1.1 fractures, 18 with type B1.2, 16 with type B1.3, 44 with type B2.1, 5 with type B2.2, 12 with type B2.3 and 13 with type B3. All patients were treated by percutaneous internal fixation with hallo nails. Complications were recorded during follow-up including femoral head necrosis, nonunion, screw back-sliding and screw cut-out. Causes of internal fixation complications were analyzed based on the lever-fulcrum balance theory, taking the location of fulcrum, screw stress (F1), force arm of pressure (L1), resistance of screw (F2) and resistance side (L2) into consideration.Results:All patients were followed up for 1.1-77.5 months [8.2(3.6, 16.6)months]. In all, 24 patients had complications, including femoral head necrosis in 7 patients, nonunion in 3, screw back-sliding in 12 and screw cut-out in 2. The rate of femoral head necrosis of type B1, B2 and B3 was 15%(6/39), 2% (1/61) and 0%, respectively. The rate of femoral head necrosis of type B1 was higher than type B2 ( P<0.05). The nonunion rate was 3%(1/39) in type B1, 3%(2/61) in type B2, and 0% in type B3 ( P>0.05). The rate of screw back-sliding of type B1, B2 and B3 was 3%(1/39), 2%(1/61) and 0%, respectively. The rate of screw back-sliding of type B2.3 and B3 were higher than that of type B1 ( P<0.05). A trend toward a higher rate of screw back-sliding of type B2.3 and B3 was found when compared to type B2.1/2.2, but there was no significant difference ( P>0.05). Moreover, the rate of screw back-sliding showed no significant difference between type B2.3 and B3 ( P>0.05). The rate of screw cut-out was 3%(1/39) in type B1, 2%(1/61) in type B2, and 0% in type B3, which showed no significant difference between type B1 and B2 ( P>0.05). According to the lever-fulcrum balance theory, the extent of pathologic fulcrum of type B1, B2 and B3 gradually increased, resulting in increased L1 and decreased L2. The L1 of type B1, B2 and B3 was (2.2±0.5)cm, (2.8±0.4)cm and (4.7±0.5)cm, respectively ( P<0.01). The L2 of type B1, B2 and B3 was (5.1±0.5)cm, (4.7±0.5)cm, and (3.6±0.4)cm, respectively ( P<0.01). Therefore, the F1 of type B1, B2 and B3 increased progressively. Conclusions:After internal fixation, the rate of femoral head necrosis of type B1 is significantly higher than that of type B2, and the rate of screw back-sliding of type B1 is significantly lower than that of type B3. The lever-fulcrum balance theory can deepen our knowledge of reasons for complications after operation for femoral neck fractures.

ABSTRACT

Objective:To observe the clinical efficacy of Shenxie Zhitong capsule in the treatment of diabetic peripheral neuropathy(DPN) of stagnant blockade of collaterals, and evaluate its effectiveness and safety. Method:The 104 patients were randomly divided into the Shenxie Zhitong capsule treatment group (the treatment group, 53 patients) and the alpha lipoic acid group (control group, 51 patients), and two groups were compared by random and contrast test. The changes of the Toronto clinical scoring system (TCSS), utah early neuropathy scores (UENS), traditional Chinese medicine(TCM)syndrome scores, visual analysis scale (VAS), ankle brachial index (ABI), vibrating perception threshold (VPT) before and after treatment were compared between two groups, and the endpoint events, such as foot ulcers, percutaneous coronary intervention (PCI), death and composite endpoint events, related indicators of glucose and lipid metabolism and safety indicators were recorded among patients. Result:Compared with the data before treatment, the scores of TCSS, UENS, and TCM syndromes in two groups were significantly reduced (<italic>P</italic><0.01) after treatment, and VAS and glycosylated haemoglobin A1c (HbA1c) were significantly reduced (<italic>P</italic><0.05), during follow-up visit, the levels of right ABI,total cholesterol (TC), and low-density lipoprotein (LDL) in two groups were significantly reduced (<italic>P</italic><0.05), and high-density lipoprotein (HDL) level was significantly increased (<italic>P</italic><0.05). control group in control group, the 2-hour postprandial plasma glucose (2 h PG) and HbA1c levels were significantly increased (<italic>P</italic><0.05). Compared with control group, the VAS of the treatment group after treatment was significantly reduced (<italic>P</italic><0.05). After treatment and during follow-up visit, compared with control group, the 2 h PG levels of the right toe in the treatment group were significantly reduced (<italic>P</italic><0.05). There was no statistically significant difference in endpoint events and safety indicators between two groups, but the incidence trend of composite endpoint events in the treatment group was lower than that in control group. Conclusion:Shenxie Zhitong capsule has definite clinical curative effect in treating diabetic peripheral neuropathy, which is more safe and effective than alpha lipoic acid in improving pain symptoms.

ABSTRACT

Objective:To analyze the epidemiological characteristics of outbreak of infectious diseases reported in schools in Shanghai from 2014 to 2019, and to suggest related strategies for efficient response to public health emergencies. Methods:Descriptive epidemiology method was used to analyze the outbreak of infectious diseases reported in schools in Shanghai from 2014 to 2019. Results:A total of 82 infectious disease emergencies were reported in schools in Shanghai during 2014 and 2019, involving 1 760 disease cases and 2 deaths. The incidence peaks in each year were from March to June and from September to December. The events mainly occurred in kindergartens and primary schools, with 35 and 25 incidences respectively. The main types of events were hand-foot-and-mouth disease and chickenpox, accounting for 48.78% and 46.34% of public health emergencies of infectious diseases in school, respectively. The time it took to report the events was positively correlated to the duration and the scale of the events. The sooner the epidemic was reported, the shorter it lasted. Conclusion:The kindergartens and primary schools are the places with a high incidence of infectious diseases reported in schools. Measures such as regular surveillance, vaccination management, early reporting and effective handling should be executed at the early stage so as to prevent the spread of the epidemics.

ABSTRACT

A case of varicella pneumonia, hepatitis and pancreatitis after kidney transplantation was retrospectively analyzed. One week after kidney transplantation, the patient had a papule with pruritus, which was diagnosed as varicella by dermatologist as well as high-throughput sequencing. The patient was found to have pneumonia, hepatitis and pancreatitis. The individualized treatment regimen was used, including the dosage reduction of immunosuppressive agents, the blood drug concentration monitoring, antiviral therapy, anti-infection therapy, supportive treatment, and symptomatic alleviation for complications. The treatment was adjusted according to the indicators'variation. The timely review of the indicators and immunosuppressant blood concentration were performed to protect the transplanted kidney function, and the patient recovered in time. This rare case of postoperative complications of kidney transplantation were summarized and analyzed in order to accumulate clinical experience for the treatment of renal transplantation.
