Objective: To investigate the prevalence, awareness, treatment and control rates of diabetes among residents in Fangshan District, Bejing Municipality, so as to provide reference for strengthening the prevention and control of diabetes. Methods: The residents aged 18 to 79 years were selected in Fangshan District using multistage stratified cluster sampling method from March to June 2023. Demographic information, lifestyle, body mass index, fasting blood glucose, and blood lipid were collected through questionnaire surveys, physical examinations and laboratory tests. The prevalence, awareness, treatment and control rates of diabetes among residents were analyzed and their influencing factors were identified using a multivariable logistic regression model. Results: A total of 4 438 residents were enrolled, including 2 367 males (53.33%) and 2 071 females (46.67%), and had a mean age of (44.99±14.90) years. The prevalence, awareness, treatment and control rates of diabetes were 15.75%, 57.37%, 56.22% and 22.90%, respectively. Multivariable logistic regression analysis showed that age (aged 30 to 39 years, OR=1.624, 95%CI: 1.011-2.609; aged 40 to 49 years, OR=3.469, 95%CI: 2.163-5.561; aged 50 to 59 years, OR=4.202, 95%CI: 2.595-6.803; aged 60 to 69 years, OR=7.229, 95%CI: 4.406-11.862; aged 70 to 79 years, OR=7.929, 95%CI: 4.665-13.479), obesity (OR=1.368, 95%CI: 1.071-1.748), hypertension (OR=1.943, 95%CI: 1.601-2.359) and dyslipidemia (OR=2.754, 95%CI: 2.287-3.317) were the factors affecting the prevalence of diabetes. Sex (women, OR=1.529, 95%CI: 1.019-2.293), age (aged 40 to 49 years, OR=4.971, 95%CI: 1.681-14.698; aged 50 to 59 years, OR=6.070, 95%CI: 2.045-18.020; aged 60 to 69 years, OR=6.902, 95%CI: 2.287-20.832; aged 70 to 79 years, OR=6.954, 95%CI: 2.191-22.070) and hypertension (OR=1.906, 95%CI: 1.337-2.718) were the factors affecting the awareness of diabetes. Age (aged 40 to 49 years, OR=4.699, 95%CI: 1.594-13.855; aged 50 to 59 years, OR=5.990, 95%CI: 2.023-17.732; aged 60 to 69 years, OR=7.134, 95%CI: 2.370-21.470; aged 70 to 79 years, OR=6.639, 95%CI: 2.102-20.964) and hypertension (OR=1.857, 95%CI: 1.304-2.645) were the factors affecting the treatment of diabetes. Age (aged 40 to 49 years, OR=2.948, 95%CI: 1.349-6.438; aged 60 to 69 years, OR=2.344, 95%CI: 1.049-5.234) was the factor affecting the control of diabetes. Conclusions The prevalence rate of diabetes among residents in Fangshan District was high, and the improvements of awareness rate, treatment rate and control rate were not obvious. Health education and management of diabetes should be strengthened for elderly, hypertensive and dyslipidemic residents.

Objective To explore the strategies of using psychological crisis intervention in public emergencies.Methods In the early stage,psychological crisis intervention concepts and behavioral responses were formed through literature research and qualitative research methods.Use three rounds of Delphi for expert advice.Three indexes including positive coefficient,authority and coordination were used to test the reliability of expert consultation.Results Overall,it passed 239 out of 269 entries.The first round passed item 210,modified item 18,no consensus item 41;In the second round,8 new entries were added,and 22 entries were deleted through 24 entries.In the third round,there were 5 entries and 16 entries were deleted.The authority coefficient was 0.859,indicating that the experts were very familiar with the items.The coordination coefficient of three rounds of consultations were 0.464,0.696,and 0.407 (P＜0.001)respectively,showing that the coordination degree of experts was excellent,the credibility of feedback was high,and results were highly reliable.Conclusions The strategies of field psychological crisis intervention for public emergencies developed in this study received the consensus by domestic psychological crisis intervention experts,it is will provide a basis for systematic,comprehensive and effective guidance for this work.

Objective To study gross α and gross β radioactivity in environmental samples in Wuxi, China, and perfect the radioactivity data, and to discover possible radioactive contamination in time. Methods The BH1227 low-background α and β measuring instrument was used to determine gross α and gross β radioactivity in sedimentary dust, aerosol, drinking water, and food samples in Wuxi. Results Among environmental samples collected in Wuxi, 2014—2019, the mean gross α and gross β radioactivity levels were 0.01～5.98 Bq/kg and 9.47～547.86 Bq/kg in food samples, respectively, 1.2～22 mBq/L and 0.1～141 mBq/L in water samples, respectively, 39～44790 mBq/m³ and 743.1～101500 mBq/m³ in sedimentary dust samples, respectively, and 50～1125 μBq/m³ and 38～9510 μBq/m³ in aerosol samples, respectively. Conclusion We should strengthen radioactivity monitoring of environmental samples in Wuxi through increasing the scope and frequency of monitoring, to perfect baseline radioactivity data of Wuxi.

Background:Patients with primary biliary cholangitis(PBC)may develop gastroesophageal varices at an early stage.It is of great significance to prevent variceal bleeding for the long-term outcome of PBC.Aims:To assess the risk factors for clinically significant portal hypertension(CSPH)among PBC patients and develop a predictive model.Methods:The clinical data of PBC patients admitted from January 2018 to January 2022 in the Division of Gastroenterology and Hepatology,Renji Hospital,Shanghai Jiao Tong University School of Medicine were retrospectively collected and analyzed.Patients were divided into CSPH and non-CSPH groups according to the diagnostic criteria of CSPH.Multivariate Logistic regression and Lasso regression were used to identify the risk factors and construct CSPH predictive model which was presented as nomogram and internally validated.Results:Of the 458 subjects enrolled in this study,140 cases were in CSPH group while 318 cases in non-CSPH group.Multivariate analysis identified that male gender(OR=2.89),positive for anti-centromere antibody(ACA;OR=2.18)and anti-gp210 antibody(OR=1.75),high baseline total bilirubin(OR=1.01)and IgA(OR=1.27),and low baseline albumin(OR=0.91)and platelet count(OR=0.98)were independent risk factors for CSPH.These variables were selected to form the predictive model and nomogram ultimately.Favorable stability and predictive performance of the model were confirmed by ROC curve analysis(AUC=0.891)and bootstrap method(C-index=0.891).Conclusions:The predictive model constructed in this study has certain reference value for risk stratification of CSPH among PBC patients.Intensive follow-up is recommended for ACA-positive PBC patients in clinical practice for avoidance of gastroesophageal variceal bleeding.
