Objective:To investigate the changing trend of mortality rate and death cause spectrum among household-registered residents aged 60 and above in Beijing from 2007 to 2020.Methods:The mortality data was collected from the Beijing Death Information Registration and Management System. We calculated the mortality rates and constituent ratios by gender, age groups, and death causes and estimated the changing trend of mortality rate and average annual percent change (AAPC) by Joinpoint 4.3.1.Results:The crude mortality rate decreased from 27.62‰ in 2007 to 23.55‰ in 2020 (AAPC=-1.18%, P<0.001), and the standard rate also decreased from 25.39‰ in 2007 to 19.85‰ in 2020 (AAPC=-1.68%, P<0.001) among registered residents aged 60 and above in Beijing. The top 5 causes of death were heart diseases, malignant tumors, cerebrovascular diseases, respiratory diseases, and endocrine and nutritional metabolic diseases, accounting for 87.1% of the total deaths. The mortality rates of heart diseases (AAPC=-1.08%, P=0.024), cerebrovascular diseases (AAPC=-3.79%, P<0.001), malignant tumors (AAPC=-0.31%, P=0.006) and respiratory diseases (AAPC=-5.56%, P=0.007) showed a decreasing trend. The rate of injury and poisoning showed an increasing trend (AAPC=1.54%, P=0.001), while no statistically significant change was found in endocrine and nutritional metabolic diseases mortality rates (AAPC=-1.46%, P=0.054). Conclusions:The mortality rate of registered residents aged 60 years and over in Beijing showed a downward trend from 2007 to 2020. Heart diseases, cerebrovascular diseases, malignant tumors, and respiratory diseases should be treated as the key diseases for prevention and control, and targeted measures should be taken to improve the health level of the elderly population.

Abstract Flood disasters are the common public health emergencies, mainly leading to environmental damage, water pollution, food pollution, vector breeding, infectious disease epidemic and other risk factors of sanitary and anti epidemic work. The guideline has been formulated with reference to the technical documents such as Guideline for Environmental Sanitation Disposal and Preventive Disinfection in Flooded Areas and Technical Proposal for Sanitary and Anti epidemic Measures after Flood Disasters, as well as the latest research progress at home and abroad. In order to guide the sanitary and anti epidemic measures in flooded areas, protect the health and safety of students and teachers and ensure the normal educational and teaching order, the guideline introduces the key measures that should be taken by schools, teachers and students in flood striken areas.

Objective:To understand the construction status of research wards in the first model research wards in Beijing, and provide reference for promoting their high-quality development.Methods:From July to September 2022, a questionnaire survey was conducted on the setting mode, facility deployment, operational efficiency, and implementation of supportive policies of the research wards among the first batch of model research wards in Beijing. Descriptive analysis was used to analyze the questionnaire data.Results:The 8 hospitals surveyed had all set up specialized research wards; 5 of them had shared research wards, including 4 general hospitals and 1 specialized hospital. The number of research ward beds in each hospital ranged from 31 to 120, with only 1 hospital having research ward beds accounting for 11.3% of the hospital′s beds, while the other 7 hospitals were less than 10.0%. Compared with 2020, the number of clinical research projects carried out in the research wards of 8 hospitals in 2021 have increased by a total of 403, while the ethical review time was less than or equal to 14 working days, 2.5 working days shorter than 2020; 4 hospitals could complete the experimental project approval within 60 working days and the first visit within 22 working days, while 5 hospitals could complete the research conclusion within 14 working days. There were 2 hospitals that link the performance evaluation of research wards with salary distribution, and 3 hospitals link it with professional title evaluation and employment.Conclusions:The model research wards in Beijing have adopted different setting modes for the construction of research wards, all operating well. It is recommended to further improve such areas as selecting a research ward setting mode to fit the needs of the hospital, optimizing and integrating the resource allocation of research wards, improving operational efficiency to increase market competitiveness, and effectively implementing supportive policies related to human resource management. These practices can better promote the high-quality construction of research wards and comprehensively enhance the supportive role of clinical research in pharmaceutical and healthcare collaborative innovation.

Objective:To understand and compare the differences between age, sex and liver diseases-related mortality risk in patients with hepatitis B virus-related liver cirrhosis.Methods:Based on the front-page inpatient medical record database and the death registration system of Beijing patients with hepatitis B-related liver cirrhosis from 2008 to 2015 were included. The survival information of all patients were traced up to the occurrence of liver disease-related mortality event or until December 31, 2019. Kaplan-Meier method was used to calculate the cumulative incidence of liver disease-related mortality in patients with liver cirrhosis. Cox regression model was used to analyze the effect of age-gender interaction on liver disease-related mortality risk.Results:A total of 16 738 patients with hepatitis B-related liver cirrhosis were included, of which 13 969 cases (83.46%) were in compensated stage and 2 769 cases (16.54%) were in decompensated stage. Liver cirrhosis complications mortality risk in patients with compensated stage cirrhosis at 3, 5, and 8 years were 10.84%, 12.70%, and 14.37%, respectively; while in decompensated stage patients, the mortality risk was 16.70%, 19.02%, and 20.73%, respectively. The 3, 5, and 8-year liver cancer mortality rates of patients with compensated stage liver cirrhosis were 5.24%, 7.49%, and 10.25%, respectively; while those with decompensated stage liver cancer mortality rates were 9.01%, 11.16%, and 13.50%, respectively. Liver disease-related mortality risk was increased with age in patients with liver cirrhosis. Liver cirrhosis complications mortality risk in female patients with liver cirrhosis at age < 60 years was lower than that of male patients. Liver cirrhosis complications mortality risk in male and female patients aged 60-69 years were similar. Liver cirrhosis complications mortality risk in female patients aged ≥70 years was higher than that of male patients. However, female patients had a lower risk of liver cancer mortality than male patients in utmost age groups.Conclusion:Age is positively correlated with liver diseases-related mortality risk in patients with hepatitis B-related liver cirrhosis. Female sex is a protective factor for liver cancer mortality in patients with liver cirrhosis, and the protective effect on liver cirrhosis complications mortality risk gradually disappears with age.

Objective: To evaluate comprehensive health status of 31 provinces in China and compare with other countries (regions). Methods: Social-demographic index, life expectancy and healthy life expectancy in 134 countries (regions) and 31 provinces in China were collected from the Global Burden of Disease Study 2015. K-means clustering method was used to classify comprehensive health status of various countries (regions) in the world. HemI 1.0.3 software was applied to draw distribution heat maps of social-demographic index, life expectancy and healthy life expectancy in different provinces of Mainland China. Discriminant analysis was used to evaluate comprehensive health status of different provinces in Mainland China. Results: Comprehensive health status of 134 countries (regions) was grouped into category 1-8 from good to poor, and Mainland China was in the category 4. The comprehensive health status of provinces in Mainland China is better in the east coast and poorer in the west inland, among which Shanghai and Beijing were grouped into the category 1, Zhejiang, Jiangsu, Guangdong and Tianjin into the category 2, Fujian, Liaoning and Shandong into the category 3, Yunnan, Guangxi, Xinjiang and Guizhou into the category 5, Qinghai and Tibet into the category 6, and the rest 16 provinces into the category 4. Conclusion Comprehensive health status of Mainland China ranked middle to upper level in the world, and health status disparities were observed among different provinces in Mainland China.

Objective To evaluate the efficacy and safety of Houpu Paiqi mixture in treatment of functional dyspepsia (FD)with abdominal distension symptom.Methods From July 2014 to June 2015 , in nine centers,a total of 162 FD patients with abdominal distension symptom and met Rome Ⅲpostprandial distress syndrome (PDS)diagnostic criteria were enrolled.All patients were randomly divided into trial group and control group,81 patients in either group.The patients of trial group and control group took Houpu Paiqi mixture or placebo,respectively,25 mL per time,twice daily,and both the courses of treatment were two weeks.Before and after the treatment,the improvement of main symptoms,total clinical efficacy rate and efficacy of traditional medicine between two groups were compared.Chi square test,Fisher exact probability method and Wilcoxon test were performed for statistical analysis.Results According to the results of per-protocol (PP)analysis,the total efficacy rate of trial group and control group was 69.4% (50/72)and 59.2% (42/71),respectively,and there was no statistically significant difference in total efficacy rate between the two groups (χ2 =1 .650,P =0.199 ). And there was no statistically significant difference in the improvement of PDS main symptoms(postprandial fullnessand early satiety)between the two groups (56.3% ±27.9% vs 54.4% ±32.1%,t =0.606,P =0.727 ).For those with baseline symptom score over 14,median early satiety score of trial group after the treatment was 0,which was lower than that of control group,and the difference was statistically significant (Z =-2.370,P =0.018).The total efficacy rate of traditional medicine of trial group was 80.8% (59/73 )and that of control group was 72.0% (54/75 ),and the difference was not statistically significant (χ2 = 0.676,P =0.411 ).Conclusion Houpu Paiqi mixture has certain efficacy in FD with abdominal distension,and could be used for the treatment of PDS-predominant FD.

Objective To understand the probability of premature mortality caused by non-communicable diseases (NCD) in Beijing from 2010 to 2015.Methods The data of deaths from Beijing vital registration system were used to analyze age-standardized NCD mortality rates,proportion of NCD deaths in age group ＜70 years and premature NCD mortality.Results NCD deaths accounted for 90％ of the total deaths in Beijing.Age-standardized NCD death rate decreased from 332.43/100 000 in 2010 to 280.02/100 000 in 2015.Meanwhile,the probability of deaths from four NCDs between in age group 30-70 years (premature NCD mortality) decreased from 12.81％ to 11.11％ in Beijing.The premature mortality of four NCDs in men was 14.63％,and compared with 2015 baseline,it would decrease by 16.4％ to reach 2025 goal (12.23％),and the probability of premature mortality four NCDs in women was 7.54％,and compared with 2015 baseline,it would decrease by 6.8％ to reach the 2025 goal (7.03％).People living in suburb areas had a higher probability of premature NCD mortality (13.67％) than those living in urban areas (9.72％) in Beijing in 2015.Conclusions The premature NCD mortality was much higher in men than in women in Beijing.More attention should be paid to the control of risk factors for NCD premature deaths,especially in men and in suburb residents,to reach the 25 × 25 goal.
