Objective: To investigate the personnel allocation, structure, and mobility situation of the disease prevention and control (CDC) institutions in Jinhua City, Zhejiang Province from 2018 to 2024, so as to provide insights into strengthening the construction of the talent team within CDC institutions. Methods: Basic information of the personnel in the CDC institutions, Jinhua City were collected through the Basic Information Subsystem of the China Disease Control and Prevention Information System. Composition of age, gender, educational background, major, professional title of the in-service and officially employed personnel, as well as the situation of personnel mobility were analyzed using descriptive methods. Results: A total of 10 CDCs were established in Jinhua City by the end of 2024, including 1 municipal CDC and 9 county (city, district) CDCs, with an approved staffing of 672 people and 621 in-service and officially employed staff. Compared with 2018, the approved number of staff positions in the CDC institutions of Jinhua City increased by 21.30% in 2024, and the number of in-service and officially employed staff members increased by 22.73%. From 2018 to 2024, the number of CDC staff per 10 000 permanent residents in the CDC institutions of Jinhua City, the municipal CDC, and the county (city, district) CDCs were 0.764 to 0.932, 0.142 to 0.173, and 0.623 to 0.759, respectively. From 2018 to 2024, the overall male-to-female ratio in both the municipal CDC and the county (city, district) CDCs decreased from 1.04∶1 and 0.84∶1 to 0.95∶1 and 0.75∶1, respectively. In the municipal CDC, the proportion of staff aged 25-<45 years old increased from 57.45% to 69.02%; the proportion of staff with a bachelor's degree or above increased from 79.79% to 93.81%; the proportion of staff majoring in public health increased from 37.23% to 49.56%; the proportions of staff with various professional titles were relatively stable; 51 staff members joined, all of whom had a bachelor's degree or above; 32 staff members left, among whom 24 retired and 6 were admitted to civil service positions or other units. In the county (city, district) CDCs, the proportion of staff aged 22-<35 years old increased from 30.59% to 37.40%; the proportion of staff with a bachelor's degree or above increased from 71.85% to 89.76%; the proportion of staff majoring in public health increased from 46.60% to 54.33%; the proportion of staff with a junior professional title or below increased from 34.47% to 43.50%; 198 staff members joined, and 194 of them had a bachelor's degree or above; 102 staff members left, among whom 67 retired and 28 were admitted to civil service positions or other units. Conclusions From 2018 to 2024, the number of in-service and officially employed staff in Jinhua CDC institutions increased the academic qualifications and professional composition continue to improve. There are still problems with the number of CDC staff per 10 000 permanent residents being lower than the standard for the personnel establishment in Zhejiang CDCs, a lack of high-level talents, and insufficient personnel stability.

Objectives:To explore the risk factors for death from ruptured acute aortic dissection during emergency treatment,construct and validate a risk prediction model for death from ruptured acute aortic dissection during emergency treatment. Methods:A total of 301 cases of acute aortic dissection patients who were admitted to Chinese Academy of Medical Sciences Fuwai Hospital from January 2018 to August 2021 were included in this study.Patients were divided into survival subgroup(n=239)and death subgroup(n=62)according to whether dissection rupture occurred in the acute stage of the disease.Univariate and multivariate analyses were performed.Logistic regression analysis was used to establish the risk prediction model.The Hosmer-Lemeshow test was conducted to assess the model's goodness of fit,and the receiver operating characteristic curve(ROC curve)was used to evaluate the model's predictive performance.A prospective validation was performed on 129 cases of acute aortic dissection patients admitted to our hospital's emergency department from September 2021 to September 2022. Results:Among the 301 cases of acute aortic dissection patients,there were 62 cases of rupture and death,with an incidence rate of 20.6%.The results of multivariate analysis showed that age(OR=1.066,95%CI:1.034-1.099),type A dissection(OR=0.045,95%CI:0.006-0.364),history of hypertension(OR=0.377,95%CI:0.167-0.850),and concomitant hypotension(OR=4.424,95%CI:1.467-13.340)were determinants of deaths.The model formula was Z=-5.624+0.064×age-0.976×history of hypertension(yes=1,no=0)-3.104×type(Type A=0,Type B=1)+1.487×concomitant hypotension(yes=1,no=0).The Hosmer-Lemeshow test result showed χ2=9.328,df=8,P=0.315,the area under the ROC curve was 0.874,sensitivity was 79.0%,specificity was 81.6%,and the maximum Youden index was 0.606.The model validation result showed that the area under the ROC curve was 0.722,sensitivity was 73.7%,specificity was 69.1%,and accuracy was 89.9%. Conclusions:Age,history of hypertension,dissection type,and combined hypotension are predictors of the risk prediction model for death from dissection rupture in patients with acute aortic dissection during emergency treatment.The model constructed in this study has good predictive performance,which can provide reference for medical staffto quickly identify high-risk patients for death from ruptured acute aortic dissection and timely predictive measures could be highlighted in indicated cases.

BACKGROUND:Mesenchymal stem cells are multipotent stromal cells isolated from bone marrow,fat,umbilical cord and other tissues.It can differentiate into different cell types and secrete a variety of proteins with therapeutic potential,which has a good application prospect in the repair of muscle tissue. OBJECTIVE:To review the research progress of mesenchymal stem cells in promoting muscle tissue repair and provide a theoretical basis for further clinical application. METHODS:Relevant articles published from inception to 2022 were retrieved from CNKI,VIP,WanFang,PubMed,Embase and Web of Science databases.The keywords were"mesenchymal stem cells,muscle tissue,muscle injury,muscle atrophy,exosomes,scaffolds"in Chinese and English.The literature about mesenchymal stem cell migration promoting muscle fiber proliferation and repair was screened.Finally,98 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)The related mechanisms of mesenchymal stem cell migration promoting muscle fiber proliferation and repair are complex,mostly by anti-inflammatory,inhibiting interstitial fibrosis,inhibiting the fat formation and other ways to promote muscle fiber proliferation and repair.(2)The related biological scaffolds and cell co-culture based on mesenchymal stem cells can significantly compensate for the low survival rate of mesenchymal stem cells after colonization.(3)At present,mesenchymal stem cell therapy still has apparent limitations.In the future,mesenchymal stem cells combined with other therapies should become the primary development trend.

The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.How-ever,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive rela-tionship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met's anti-proliferative effects were blocked by AMPK inhibitor or YAP1 over-expression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation.
