Objective To explore the quantitative evaluation of integrity risk prevention and control in public hospitals,provide reference for improving the quality and efficiency of integrity risk prevention and control.Methods Self-designed"Inspection Standards for Integrity Risk Prevention and Control of Power Matters in Public Hospitals"was used to score and rate the power matters provided by each functional department/clinical department of West China Hospital of Sichuan University from three aspects:the clarity of power operation process,the accuracy of finding integrity risk points,the effectiveness of prevention and control measures.Results A total of 236 power matters of the hospital were inspected for integrity risk prevention and control,and according to the inspection criteria,57 items were rated as first grade,103 items were rated as second grade,and 76 items were rated as third grade,accounting for 24.15％,43.64％and 32.20％,respectively.The score for the special work of integrity risk prevention and control was 5.82±1.92 points,of which the process dimension score was 2.11±0.75 points,the risk points dimension score was 1.89±0.92 points,the prevention and control dimension score is 1.89± 0.79 points,which reflects the problems of unclear workflow,inaccurate finding of individual risk points,and unspecified prevention and control measures in some units.Conclusion Hospitals should focus on the concreteness,accuracy,salience and quantification in the long-term construction of integrity risk prevention and control from the aspects of thought,behavior,effectiveness and evaluation.

Objective:To construct and validate a predictive model for the occurrence of malignant cerebral edema(MCE)in the elderly with acute large hemispheric infarction(LHI)of the anterior cerebral artery.Methods:Clinical, laboratory and imaging data of 301 elderly patients with acute LHI of the anterior cerebral artery admitted to the Department of Neurology of the Third Affiliated Hospital of Soochow University between January 2018 and April 2023 were retrospectively analyzed.Patients were divided into a modeling group(211 cases)and a validation group(90 cases)by the simple random sampling method with a ratio of 7∶3.According to the occurrence of MCE, univariate and multivariate Logistic regression analyses were performed with data from the modeling group to screen for independent predictors of the development of MCE.Nomograms were created and internally validated using R software.Additionally, external validation was performed with data from the validation group, and the performance of the model was assessed by receiver operating characteristic(ROC)curves, calibration plots, and clinical decision curve analysis(DCA), respectively.Results:The MCE incidence and baseline data between the modeling and validation groups were not statistically significantly different and were actually comparable.Multivariate Logistic analysis in the modeling group showed that a history of atrial fibrillation( OR=3.459, 95% CI: 1.202-9.955, P=0.021), Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score( OR=1.202, 95% CI: 1.052-1.373, P=0.007), National Institutes of Health Stroke Scale(NIHSS)score( OR=1.163, 95% CI: 1.039-1.3013, P=0.008), Alberta Stroke Program Early CT Score(ASPECTS)( OR=0.782, 95% CI: 0.639-0.958, P=0.018), and collateral score(CS)( OR=0.414, 95% CI: 0.221-0.777, P=0.006)were independent predictors of the occurrence of MCE in the elderly patients with LHI.Based on the nomogram model constructed using the independent predictors, the ROC value for the risk of developing MCE was 0.912(95% CI: 0.867-0.957)in the modeling group and 0.957(95% CI: 0.902-0.997)in the validation group.The predicted probabilities from the nomograms in the modeling and validation groups were close to the actual probabilities, indicating good calibration.The DCA curves in the validation group showed that the predictive model had good clinical utility. Conclusions:The nomogram model established in this study exhibits good discrimination and calibration for the prediction of MCE, and has some predictive value.

Objective: To explore the relationship between abuse experience with suicidal ideation and suicide attempts of junior middle school students, and to provide a reference for suicide prevention of junior middle school students. Methods: Cluster sampling method were used to selct 10 289 junior middle school students from 25 districts and counties of Chongqing were included in the analysis of this study from July to September in 2020. And Questionnaire on Abuse in Childhood and Mental Health Scale for Middle School Students were applied to collect the data about demographic information, suicide ideation and behavior. Results: The prevalence of suicidal ideation and suicide attempts among junior middle school students were 20.93% and 10.83%, respectively. Multivariate Logistic regression model found that after controlling for demographic variables and mental health, emotional abuse ( OR =2.07) and emotional neglect ( OR =2.03) showed higher correlations with suicidal ideation than the other three types of childhood abuse( OR physical neglect =1.19, OR physical abuse =1.60, OR sexual abuse =1.37, P <0.05); and sexual abuse ( OR =2.29) and physical neglect ( OR =1.87) showed higher associations with suicide attempt than the other three types of abuse( OR emotional abuse =1.63, OR emotional neglect =1.59, OR physical abuse =1.50, P <0.01). Conclusion All five types of child abuse were independent risk factors for suicidal ideation and suicide attempts, and emotional neglect and emotional abuse had a greater effect on suicidal ideation, sexual abuse and physical neglect had a greater effect on suicide attempts.

Objective: To investigate the relationship between the maximum thickness of carotid atherosclerotic plaque and the incidence of complications after carotid stenting in patients with severe carotid stenosis. Methods: The clinical data of 85 patients with severe carotid stenosis undergoing CAS were analyzed. The maximum thickness of carotid plaque was evaluated according to ultrasound imaging data.Patients were divided into two groups according to the optimal threshold value: 0.435 mm, which calculated in the ROC curve of plaque thickness. The incidence of complications within two years after CAS was analyzed. Results: 85 patients were followed up for 2 years: restenosis occurred in 12 cases, the incidence rate was 14.1%, which was significantly correlated with the maximum thickness of atherosclerotic plaque(P=0.002). Postoperative restenosis occurred in 2 cases (3.70%) in group A and 10 cases (32.26%) in group B(P<0.001); Three cases (9.68%) suffered from relapsing cerebral infarction in group B compared to none in group A(P=0.020). Conclusion With the carotid plaque growing thicker, the incidence of restenosis after CAS in patients with carotid stenosis increases. Especially in patients whose maximum plaque thickness is more than 0.435 mm, the incidence of restenosis postoperative increases remarkably.

Objective To understand the status of knowledge,attitude,and practice of schistosomiasis prevention and con-trol and infection status in Armed Police Forces stationed along the Yangtze River,so as to provide the reference for formulating the schistosomiasis prevention and control measures in Armed Police Forces. Methods A questionnaire survey was conducted in the Armed Police Forces along the Yangtze River in Jiangsu Province,and the investigation content included social demo-graphic data,schistosomiasis prevention knowledge,attitude and behavior. All the subjects were examined for Schistosoma ja-ponicum infection. Results Totally 376 soldiers were investigated in 2 sites. The total passing rate of schistosomiasis knowl-edge was 72.87%. The passing rate among different age groups had no significant difference( χ2 =0.26,P > 0.05). The passing rate of soldiers from endemic areas was significantly higher than that of the soldiers from non-endemic areas( χ2 =4.71,P <0.05). The passing rate of officers was significantly higher than that of the soldiers(χ2 = 4.21,P <0.05). The passing rate of sol-diers with the education levels of junior school,high school,college,undergraduate and above increased gradually,with a sig-nificant difference( χ2 =8.16,P < 0.05). The soldiers with positive attitude accounted for 93.88%. Among the water contact be-haviors,training accounted for 17.55% and participating in the task(such as flood fighting and water work)accounted for 86.44%. When launching,the rate of taking protective measures was 52.93%. The rate of taking protective measures in the knowledge passing group was much higher than that in the knowledge failed group( χ2 =10.55,P < 0.05). The stool was harm-lessly treated in the two camps. Among 376 soldiers,the positive rate of blood examinations was 0.53%,but the stool examina-tions were all negative. Conclusions The overall level of knowledge and correct behavior of schistosomiasis prevention in the Armed Police Forces along the Yangtze River still should be improved. The better health education and behavior intervention are crucial to schistosomiasis prevention in the army.

Objective To analyze the Oncomelania hupensis snail distribution and the changes of snail situation in Chang-zhou City from 2013 to 2016,so as to provide the evidence for formulating the schistosomiasis prevention and control interven-tions. Methods The data of snail monitoring in Changzhou City from 2013 to 2016 were collected and statistically analyzed. Re-sults The total area with snails was 40.17 hm2 and the newly discovered area was 30.63 hm2 in Changzhou City from 2013 to 2016. In the four years,3454 snails were dissected,and no schistosome infected snails were found. There were totally 51 spots with snails,and the areas with snails of different types of marshland,inland and mountain were 12.13(30.19％),25.54 hm2 (63.57％)and 2.51 hm2(6.24％),respectively. In the newly discovered snail environment,the areas of types of marshland and inland were 8.00 hm2(26.12％)and 22.63 hm2(73.88％),respectively. The main causes for snail existence were external input and adjacent diffusion. In the past four years,the total snail control area with molluscicides was 71.74 hm2,the consolidated snail control area with molluscicides was 155.15 hm2,and the total environmental modification areas in the current snail spots and historic snail spots were 15.90 hm2 and 11.30 hm2 respectively. Conclusion The diffusion of snails in inland rivers is the key of the newly discovered snail areas in Changzhou City in recent years,and the snail monitoring and control measures should be strengthened in the future.
