Objective:To analyze the epidemiological characteristics of the population receiving assisted reproductive technology (ART) therapy and the health status of their offspring in Shanghai from 2011 to 2020.Methods:Based on the birth cohort of the entire population in Shanghai, the proportion and trend changes of ART offspring in the birth cohort were analyzed. The characteristics of ART and naturally conceived populations, including household registration, education level, maternal age, and reproductive history, were examined. Additionally, the health status between ART offspring and naturally conceived offspring were compared.Results:From 2011 to 2020, a total of 70 729 ART offspring were born in Shanghai, accounting for 3.69% of the total births. In 2020, this proportion reached 7.79%. The ART conception rate for primiparous women was higher than that for multiparous women, with both showing upward trends and reaching 9.87% and 2.36%, respectively, in 2020. The ART conception rate was higher in women with higher education levels and local household registration than in those with lower education levels and non-local household registration. The incidence rates of preterm birth and low birth weight in ART singleton offspring were 7.76% and 4.82%, respectively, higher than the 4.69% and 2.87% in naturally conceived offspring, but no increasing trend was observed in naturally conceived offspring. Among twin and multiple newborns, the incidence rates of preterm birth and low birth weight were 56.98% and 46.82% for ART, lower than the 58.51% and 51.32% for natural conception.Conclusions:The difference in social and demographic characteristics was obvious in population receiving ART, suggesting that the differed demand of some people for ART therapy, and it is necessary to strengthen the construction of public health services and further expand the coverage and accessibility of ART services. With technological advancements, the rates of preterm birth and low birth weight remain relatively stable, and even decrease in twin and multiple newborns.

ObjectiveTo introduce the basic design, development plan and objectives of a population-based birth cohort in Shanghai, and further present the main data and baseline characteristics of enrolled participants in the cohort, and to provide key information for reproductive health-related studies. MethodsThe Shanghai population-based birth cohort initiated on January 1, 2005, included newborns born in Shanghai every year and their parents, and collected information on reproductive health, reproductive treatment, birth characteristics, growth and development status, as well as the incidence, treatment and death of diseases by employing data linkage technology and investigations. This formed a birth cohort spanning the entire life cycle. ResultsAs of October 2022, a total of 2 978 538 newborns and their parents were included in the cohort. Among them, 2 905 135 (97.54%) were naturally conceived (NC), and 73 403 (2.46%) were born through assisted reproductive technologies (ART). The average age of parents was (32.56±4.12) years old for females and (34.62±5.34) years old for males in the ART group, which was higher than (28.02±4.71) years and (30.07±5.54) years for parents in the NC group. Among parents, females and males aged 30 and above accounted for 77.12% and 85.08%, respectively, which were higher than that of parents (35.28% for females and 49.66% for males) in the NC group. Furthermore, the percentage of parents with a college degree or above in the ART group was 73.23% for females and 73.66% for males, which were higher than those in the NC group (49.98% and 50.91%, respectively). The multiple births rate in the ART group was 33.81%, which was higher than that in the NC group (1.88%). The incidence of premature birth and low birth weight in the ART group were 24.47% and 19.08%, respectively, which was higher than that in the NC group (5.47% and 3.73%). ConclusionThe comprehensive collection of reproductive health-related information in the birth cohort in Shanghai can provide essential resources to determine the influence of genetics, environment, reproductive treatment and other related factors on the health of offspring after birth.

Objective:To investigate health status and calculate health life expectancy (HE) of residents in Shanghai, analyze health related factors and provided foundation of health policy.Methods:A multi-stage stratified random sampling was used to obtain self-reported health survey in Shanghai. WHO questionnaire was used to evaluate the health quality of life which was designed for the world health survey, Sullivan's method was used to calculate HE.Results:The self-assessment disability measure for adults over 18 years old in Shanghai was 0.25, higher for women (0.28) than for men (0.23). LE was 65.76 years for adults over 18 years old, higher for women (68.22) than for men (63.39). HE for adults over 18 years old was 47.99 years old, higher for men (49.05) than women (47.14). HE's proportion in LE gradually decreases with age. It accounts for 72.97% in the 18 years old and 39.00% in the 85 years old.Conclusions:The health of adult male in Shanghai is higher than that of female, and the proportion of HE loss of elderly is higher than young people. It is necessary to focus on the aging problem and strengthen the long-term care and health support system for the elderly. Improve the prevention and control of major diseases such as chronic diseases,which affect the quality of life expectancy seriously. Promotes the health level and quality of life in Shanghai.

Objective:To analyze the difference of life expectancy and healthy life expectancy among Shanghai residents of different gender and age groups.Methods:Compare the trends of life expectancy among Shanghai and other longevity countries/regions. With the disability weights of GBD, Sullivan method was applied to calculate the healthy life expectancy in Shanghai and analyze the loss of healthy life years among the population of different age groups and genders.Results:In the past 40 years, life expectancy had increased by 10.86 years in Shanghai. In 2016, the life expectancy of Shanghai residents was 83.18 years old, and 80.83 years old for males and 85.61 years old for females. The healthy life expectancy of Shanghai residents was 69.46 years, and 68.68 years for males and 70.23 years old for females. The gap with life expectancy was 13.72 years old, 12.15 years old and 15.38 years old, respectively. They account for 16.49%, 15.02% and 17.97% of life expectancy, respectively. The healthy life expectancy of women in all age groups is higher than that of men with the average gap of 1.76 years. The difference between the two is as small as 1.36 years at 20-24 years old, and as large as 2.24 years at 70-74 years old. The loss rate of healthy life expectancy increases with age, with women higher than men before age 65 and vice versa after age 65 years old.Conclusions:The life expectancy in Shanghai has reached the world leading level, but the healthy life loss is still large. It is necessary to further improve the life quality with the reducing mortality rate, especially for women and men over 65 years old.

OBJECTIVE:
Few studies investigating associations between fine particulate air pollution and hemorrhagic stroke have considered subtypes. Additionally, less is known about the modification of such association by factors measured at the individual level. We aimed to investigate the risk of fatal intracerebral hemorrhage (ICH) incidence in case of PM (particles ≤ 2.5 μm in aerodynamic diameter) exposure.
METHODS:
Data on incidence of fatal ICH from 1 June 2012 to 31 May 2014 were extracted from the acute stroke mortality database in Shanghai Municipal Center for Disease Control and Prevention (SCDC). We used the time-stratified case-crossover approach to assess the association between daily concentrations of PM and fatal ICH incidence in Shanghai, China.
RESULTS:
A total of 5286 fatal ICH cases occurred during our study period. The averaged concentration of PM was 77.45 μg/m. The incidence of fatal ICH was significantly associated with PM concentration. Substantial differences were observed among subjects with diabetes compared with those without; following the increase of PM in lag2, the OR (95% CI) for subjects with diabetes was 1.26 (1.09-1.46) versus 1.05 (0.98-1.12) for those without. We did not find evidence of effect modification by hypertension and cigarette smoking.
CONCLUSIONS
Fatal ICH incidence was associated with PM exposure. Our results also suggested that diabetes may increase the risk for ICH incidence in relation to PM.

OBJECTIVETo investigate the expression of SOX2 in cervical intraepithelial neoplasia (CIN) and cervical cancer and explore its association with the clinical features.
METHODSSOX2 expressions were examined using immunohistochemical method in 10 normal cervical tissue specimens, 36 cervical intraepithelial neoplasia specimens (including 10 cases of grade I, 12 of grade II, and 14 grade III) and 40 cervical cancer specimens (including 21 cases of stage I and 19 of stage II). The correlation between the immunohistochemical results and the clinical features of the patients was analyzed.
RESULTSSOX2 expression was negative in normal cervical tissues, and was positive in 41.6% of CIN specimens (10.0% in CIN I, 41.7% in CIN II, and 64.3% in CIN III) in 82.5% of cervical cancer specimens (78.2% in stage I and 88.2% in stage II). The patients with cervical cancer had a significantly higher positivity rate of SOX2 than normal control group (P<0.05). The positivity rate of SOX2 increased with the evolution of cervical disease. SOX2 protein expression was significantly correlated with the histological grade and lymph node metastasis (P<0.05), but not with the age or clinical stage of the patients (P<0.05).
CONCLUSIONSOX2 expression may serve as a useful indicator for evaluating metastasis and malignancy of cervical cancer.
