Objective To analyze the death rate and life loss of injuries in Jinshan District of Shanghai from 1990 to 2023, and to provide a scientific basis for the formulation of injury prevention and control measures. Methods Excel 2010 was used to establish a database for injury death reports in Jinshan District from 1990 to 2023, and the crude mortality rate, standardized mortality rate, age-specific mortality rate, potential years of life lost (PYLL), rate of potential years of life lost (PYLLR) and standardized rate of potential years of life lost (SPYLLR) were calculated. Results From 1990 to 2023, the crude mortality rate due to injuries in Jinshan District was 52.25/100 000, while the standardized mortality rate was 36.95/100 000. Based on the standardized mortality rate, the top four causes of injury-related deaths were traffic accidents, falls, drowning, and suicide. Traffic accidents ranked first as the leading cause of death for both males (19.30/100 000) and females (8.41/100 000). The top cause of death for the 0-14 years old group was drowning, the 15-64 years old group was traffic accidents, and the 65 years old and above was falls. Over the 34-year period, according to SPYLLR, the top four causes of death for both genders were consistently traffic accidents, drowning, suicide, and falls. Conclusion From 1990 to 2023, traffic accidents, falls, drowning, and suicide have been the primary causes of injury-related deaths in Jinshan District, Shanghai. It is essential to develop targeted prevention and control strategies based on the specific characteristics of these injury-related fatalities.

Objective To analyze the trend of death level and the probability of premature death caused by chronic obstructive pulmonary disease (COPD) in Jinshan District of Shanghai from 1980 to 2020, and to provide reference for the formulation of prevention and control measures of COPD. Methods The death cases of COPD in Jinshan District from 1980 to 2020 were collected through the death cause registration information system. The crude mortality, standardized mortality, age group mortality, early death probability and annual change percentage in different periods were calculated. Results From 1980 to 2020, the crude mortality of COPD in Jinshan District was 154.38/100 000, and the standardized mortality was 82.66/100,000. In the past 41 years, the standardized mortality of COPD showed a downward trend in males and females (APC=-1.79%, -2.52%, P<0.001). In the same period, the mortality of COPD in subjects aged 30-69 years old and subjects aged 70 years old and above also decreased (APC=-8.79%, -4.79%, P<0.001), and the probability of premature death caused by COPD showed a downward trend in males and females (APC=-9.61%, -10.71%, P<0.001). Conclusion The mortality rate and the probability of premature death of COPD in Jinshan District have decreased in the past 41 years. However, COPD is still one of the major chronic diseases that pose a serious threat to the health of residents in Jinshan District. Comprehensive prevention and treatment measures should be taken to reduce the mortality and the probability of premature death of COPD.

Objective:To determine the level of anti-measles antibody in healthy population aged 1-14 years old in Shanghai， and project the risk of measles incidence in adult population in the future， which may provide evidence for enhancing the measles immunization strategy. Methods:A cross-sectional study was conducted to collect the serum of healthy people aged 1-14 years old in an urban district hospital in Shanghai. Serum concentration of anti-measles IgG antibody was examined by enzyme-linked immunosorbent assay （ELISA） and dynamics of IgG antibody was compared. Results:The prevalence of anti-measles antibody in healthy people aged 1-14 years old was determined to be 95.29%， and the antibody protection rate was 61.86%. There was no significant difference in the distribution of antibody between men and women （P>0.05）. However， there was statistical difference in the distribution of antibody among different age groups （P<0.05）， in which the antibody showed a decreasing trend with age， especially after the age of 10 years. The lowest prevalence of anti-measles antibody and protection rate were observed in the population aged 13-14 years old， which were 87.41% and 22.96%， respectively. The GMT was 2.667 1 （equal to the concentration of anti-measles IgG antibody being 464.62 mIU/mL）. According to the fitting model Ŷ =3.217-0.04X（R²=0.943，P<0.05）， the antibody protection rate was projected to decrease to zero in the population aged 19-20 years old， whereas the anti-measles antibody was to zero in the population aged 29-30 years old . Conclusion:As there is almost no natural infection of measles，the anti-measles antibody after measles vaccine immunization showed a linearly decreasing trend with age after measles immunization．It is recommended that people aged 10-15 years should be administered intensive immunization for prevention of adults measles，which could be incorporated into current measles immunization strategies.
