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.

Objective　To conduct an epidemiological investigation and analysis on one imported cholera case in Shenzhen in 2024, providing a reference for cholera prevention and control. Methods　A cholera case and 86 close contacts in 2024 were investigated using methods of field epidemiological investigation. Real-time RT-PCR was employed for Vibrio cholerae nucleic acid detection and typing of collected specimens, followed by isolation culture, whole genome sequencing and analysis. Results　One severe cholera case was confirmed in an Indian businessman, who recovered and was discharged after rescue and rehabilitation. The pathogen was identified as the toxigenic strain of Vibrio cholerae O1 serotype Ogawa, and genetic evolution analysis showed that it had a very close genetic relationship with Vibrio cholerae isolated from multiple countries such as Bangladesh and Pakistan. Among the 86 close contacts under medical observation, no abnormalities were found. A total of 75 close contact specimens and 38 environment smear specimens from epidemic sites were collected, all testing negative. Conclusion　This is an imported cholera epidemic originating from India. The sensitivity of medical institutions to monitoring key infectious diseases such as cholera needs to be improved.

Objective: To investigate the value of the Chinese visceral adiposity index (CVAI) in predicting hypertension risk, so as to provide a tool for the early assessment of hypertension risk. Methods: Health examination individuals aged ≥18 years were selected from four medical institutes in Jinhua City, Zhejiang Province in 2022. Data on basic information, lifestyle, disease history, body mass index, waist circumference, blood pressure, and blood biochemical indicators were collected through questionnaire surveys and physical examinations. CVAI was calculated to assess levels of visceral fat accumulation, divided by quartiles into Q1, Q2, Q3, and Q4 groups. The relationship between CVAI and hypertension was analyzed using a multivariable logistic regression model, and their dose-response relationship was examined using a restricted cubic spline model. The value of CVAI in predicting hypertension risk was evaluated using receiver operating characteristic (ROC) curve. Results: A total of 23 791 individuals were enrolled, with a median age of 68.00 (interquartile range, 14.00) years. Among them, 10 178 (42.78%) were males and 13 613 (57.22%) were females. The median CVAI was 111.40 (interquartile range, 48.23). Hypertension was identified in 15 563 cases, with a prevalence of 65.42%. After adjusting for lifestyle, disease history, and blood biochemical indicators, the multivariable logistic regression analysis revealed that hypertension risk in the CVAI Q2, Q3, and Q4 groups were 2.012 (95%CI: 1.865-2.170), 3.059 (95%CI: 2.826-3.311), and 5.099 (95%CI: 4.672-5.565) times that of the Q1 group, respectively. The restricted cubic spline model revealed a non-linear relationship between CVAI and hypertension risk (Pnon linearity<0.05). Hypertension risk increased more rapidly when the CVAI was ≥81.03. The area under the ROC curve for CVAI in predicting hypertension risk was 0.691, with an optimal cutoff value of 106.01, which falls within the Q2 group. Conclusions There was a nonlinear dose-response relationship between CVAI and hypertension. CVAI can predict the risk of hypertension, and 106.01 can serve as an early warning threshold for risk screening.

Objective:To investigate the application value of a new clinical probation log designed based on the subjective-objective-assessment-plan (SOAP) structured medical record.Methods:Quantitative and qualitative studies were conducted among 97 students in the autumn semester to evaluate the effect of the new clinical probation log based on the SOAP structured medical record on their academic performance and clinical thinking. SPSS 26.0 was used to perform the t-test and ANOVA. Results:The students using the new version had a significantly better score (96.29±1.38) than those using the old version (93.53±1.60) ( P<0.001), while the multivariate analysis showed that the students who first used the old version and then switched to the new version had a significantly better improvement in the score compared with those who first used the new version and then switched to the old version ( P<0.001). The qualitative interview showed that it was necessary to use handwritten internship log, and compared with the old version, the new version could better promote the ordered clinical thinking of students. The teacher comments could give feedbacks, and all the students interviewed thought that the new version held promise for clinical application. Conclusions:The clinical probation log based on the SOAP structured medical record can help to improve the effectiveness of probation and cultivate clinical thinking ability, and thus it holds promise for application in clinical probation teaching.

Objective:To explore the pathogenesis of flunarizine-induced parkinsonism from gut-brain axis perspective.Methods:Thirty male C57BL/6 mice were randomly divided into control group and flunarizine group ( n=15). Mice in the control group were given 0.1 mL 50% polyethylene glycol 400+50% saline by gavage once/d for 2 weeks, while mice in the flunarizine group were given 6 mg/mL flunarizine+50% polyethylene glycol 400+50% saline by gavage at a daily dose of 30 mg/kg for 2 weeks. Body mass was recorded 1, 3, 5, 7, 10 and 14 d after drug administration, and motor function was assessed by rotarod test 14 d after drug administration; 16s RNA sequencing was performed in the feces to observe the intestinal flora; intestinal transit function was detected by Evans blue by gavage; and then, the mice were sacrificed and homogenate or frozen sections (brain and intestinal tissues) were prepared; dopamine-ergic neuron expression was detected by Western blotting; RT-qPCR was applied to detect the expressions of inflammatory factors in the substantia nigra, and immunofluorescent staining was used to detect the expressions of ZO-1 and Claudin-5 in the intestinal epithelial tissues. Results:Compared with the control group, the flunarizine group had lower body mass ratio 1, 3, 5, 7, 10 and 14 d after drug administration (ratio to body mass before drug administration). Compared with the control group, the flunarizine group had significantly shortened residence time in rod rotating and lower rotational speed when falling ( P<0.05). Compared with the control group, the flunarizine group had decreased tyrosine hydroxylase protein in the substantia nigra without significant difference ( P>0.05). Compared with the control group, the flunarizine group had significantly increased interleukin-6 and tumor necrosis factor-α in the substantia nigra (1.00±0.00 vs. 2.79±0.83; 1.00±0.00 vs. 3.39±1.37), significantly lower intestinal Evans blue propulsion rate (80.67%±4.51% vs. 50.67%±6.03%), and statistically decreased ZO-1 and Claudin-5 expressions in the colonic epithelial tissues (27.01±1.41 vs. 16.32±2.83; 37.00±2.80 vs. 24.52±2.12, P<0.05). Totally, 576 microorganisms were noted in both control group and flunarizine group, 744 in the control group alone, and 634 in the flunarizine group alone. The intestinal flora β diversity indices in the 2 groups were significantly different based on weighted Unifrac-principle coordinates analysis (PCoA, PCoA1: 39.88%; PCoA2: 30.69%). Compared with the control group, the microbial colony structure of mice in flunarizine group was dominated by phylum thick-walled bacteria and phylum warty microbacteria, and by families Muribaculaceae, Lachnospiraceae and Akkermansiaceae. Compared with the control group, the flunarizine group had significantly decreased relative abundance of Ackermannia spp. and Lactobacillus spp. in the intestinal flora ( P<0.05). Conclusion:Flunarizine may contribute to the pathogenesis of DIP by causing structural disturbances in the intestinal flora and inducing neuroinflammation based on the gut-brain axis.

Objective To analyze the risk factors of heart failure in patients with coronary heart disease(CHD),and to construct and verify a nomogram prediction model for the risk of heart failure in patients with CHD.Methods The clinical data of 453 patients with CHD who were hospitalized in the Second Affiliated Hospital of Shenyang Medical College from January to December 2022 were retrospectively analyzed,including 278 patients with CHD combined with heart failure and 175 patients without heart failure.The patients were divided into training group(318 cases)and validation group(135 cases)according to the ratio of 7:3.R software was applied to perform LASSO regression to screen the risk factors,and Logistic regression to establish a prediction model and construct a nomogram.The calibration curve and receiver operating characteristic(ROC)curve were used to evaluate the calibration and discrimination of the model.Results LASSO regression analysis ultimately screened five risk factors from 22 variables,and Logistic regression results showed that age,smoking,history of myocardial infarction,New York Heart Association(NYHA)cardiac function class Ⅳ,and left ventricular ejection fraction(LVEF)were all independent risk factors for heart failure in CHD patients(P＜0.05).The model formula was Z=-2.927+0.045 × age+0.886 × smoking+0.808 × history of myocardial infarction-2.829 × NYHA cardiac function class Ⅳ+0.037×LVFF.Internal validation of the model showed that area under the curve was 0.727(95％CI:0.588-0.752),the sensitivity was 40.4％,the specificity was 84.3％,and the Youden index was 0.247.According to the calibration curve,the predicted value of the calibration curve was highly consistent with the actual value,and the Brier score was 0.106.Conclusion The risk prediction model for heart failure in patients with CHD based on LASSO regression has good discrimination and prediction efficiency,which can be used as an evaluation tool for medical staff to predict the risk of patients.

A purified polysaccharide with a galactose backbone(SPR-1,Mw 3,622 Da)was isolated from processed Polygonati Rhizoma with black beans(PRWB)and characterized its chemical properties.The backbone of SPR-1 consisted of[(4)-β-D-Galp-(1]9→ 4,6)-β-D-Galp-(1 → 4)-α-D-GalpA-(1 → 4)-α-D-GalpA-(1 →4)-α-D-Glcp-(1 → 4,6)-α-D-Glcp-(1 → 4)-α/β-D-Glcp,with a branch chain of R1:β-D-Galp-(1 → 3)-β-D-Galp-(1 → connected to the →4,6)-β-D-Galp-(1 → via O-6,and a branch chain of R2:α-D-Glcp-(1 →6)-α-D-Glcp-(1 → connected to the →4,6)-α-D-Glcp-(1 → via O-6.Immunomodulatory assays showed that the SPR-1 significantly activated macrophages,and increased secretion of NO and cytokines(i.e.,IL-1β and TNF-α),as well as promoted the phagocytic activities of cells.Furthermore,isothermal titration calorimetry(ITC)analysis and molecular docking results indicated high-affinity binding between SPR-1 and MD2 with the equilibrium dissociation constant(KD)of 18.8 μM.It was suggested that SPR-1 activated the immune response through Toll-like receptor 4(TLR4)signaling and downstream responses.Our research demon-strated that the SPR-1 has a promising candidate from PRWB for the TLR4 agonist to induce immune response,and also provided an easily accessible way that can be used for PR deep processing.
