Objective: To investigate the prevalence and associated factors of chronic kidney diseases (CKD) in adult residents living in a community of Songjiang district, Shanghai. Methods: A total of 9 257 residents aged 20-75 years old in Xinqiao township of Songjiang district were selected by random cluster sampling. All the participants were interviewed to complete a set of personal questionnaire and undergo physical examinations. Urine and blood tests including markers of kidney damage and related associated factors with CKD, were carried out. Results: Eligible data from 8 207 subjects were enrolled in the study. After adjustment for age and gender, the prevalence of CKD was 8.4% (95%CI: 7.8%-9.0%), with majority of the patients (76.5%) appeared in the early stage (Ⅰ and Ⅱ) of the disease. The prevalence of CKD increased with age and higher prevalence was seen in females than in males (P<0.001). Results from logistic regression analysis showed that factors as: being elderly or female, having hypertension, hyperuricemia, and hyperlipidemia were all independently associated with CKD. Conclusions: The prevalence of CKD appeared relatively high in adult residents of Xinqiao township, Songjiang district where CKD had become a public health problem. Factors as: being female or elderly, hypertension, hyperuricemia, and hyperlipidemia were found to be associated with CKD. Our findings suggested that early prevention and control on CKD to reduce the incidence of end-stage renal diseases and related complications had called for more urgent attention.

Objective: To understand the epidemiological characteristics of one large HIV molecular transmission cluster in Jiaxing city, Zhejiang province, 2017 in order to select those people under high-risk and providing basis for programs on prevention. Methods: During 2017, newly diagnosed HIV/AIDS cases in this city were recruited. Plasma samples were collected from subjects, followed by RNA extraction, RT-PCR and nest-PCR for pol gene amplification, before being sequenced and aligned. Mega 6.0 software was used to construct phylogenetic tree, and Cytoscape 3.6.0 software was used to identify HIV molecular transmission clusters. Cases within the large transmission clusters were investigated, using a field-epidemiology-questionnaire. Data related to socio-demographics and previous sexual behaviors were collected and EpiData 3.0 and SPSS 20.0 software were used. Results: In the large transmission cluster with subtype identified as CRF07_BC, in Jiaxing, 2017, 26 cases of the total 30 cases were investigated. A total of 80.8% (21/26) could be identified as newly infected within the last two years and 30.8%(8/26) could be identified as newly infected within the last one year, including 22 cases infected locally. Among several infected cases who were at age 45 years or older, they admitted that they had experienced unprotected sexual contacts in local city for long time and having had more than 10 disclosed sexual contacts within the last two years at the local venues. Conclusions: This molecular cluster had been formed and scaled up quickly in recent two years, it has played an important role in promoting and scaling up the HIV transmission. Three cases identificed as high risk played an importantrde role in scaling up this cluster.

Objective: To evaluate the effect of health literacy and exercise-focused interventions on glycemic control in patients with type 2 diabetes (T2DM) in China. Methods: In this cluster randomized controlled trial, a total of 799 T2DM patients with most recent hemoglobin A1c (HbA1c) ≥ 7.5% (or fasting plasma glucose level ≥10 mmol/L) were recruited from 8 communities in Minhang and Changning districts of Shanghai, and randomized into a health literacy intervention group, an exercise intervention group, a comprehensive intervention group and a control group. After baseline survey and examination, a one-year intervention and 3 times (at 3(rd), 6(th), and 12(th) month) follow-up surveys were conducted. Results: The follow-up rates for all the subjects were 99.4%, 98.4% and 95.2%, respectively, at 3(rd), 6(th) and 12(th) month. Patients in intervention groups were more likely to achieve a goal HbA1c level (HbA1c <7.0%) than those in control group, with the highest glycemic control rate (25.3%) observed in comprehensive intervention group at 3(rd) month and then in exercise intervention group (25.3% and 34.6%) respectively, at 6(th) month and 12(th) month. The average levels of HbA1c in three intervention groups were lower at each follow-up time point than those at baseline survey. However, the decreases in HbA1c were obvious only at 6(th) month (P<0.001), with ls-mean (95%CI) of -0.48% (-0.71%, -0.25%), -0.33% (-0.55%, -0.11%) and -0.70% (-0.92%, -0.48%), respectively, in comprehensive, health literacy and exercise intervention groups, but it increased slightly by 0.03% (-0.19%, 0.25%) in control group. Compared with control group, the interventions were significantly associated with the decrease of HbA1c level, with the most improvement observed in comprehensive group (β=-0.47, 95% CI: -0.73, -0.20) at 3(rd) month, and in exercise intervention group at 6(th) month (β=-0.73, 95%CI: -0.98, -0.47) and at 12(th) month (β=-0.75, 95%CI: -1.05, -0.45) of follow-up. Stratified analyses showed that patients with lower health literacy level could benefit from any intervention, while those with higher numeracy skill benefited more from exercise intervention. Conclusion: Both health literacy and exercise-focused interventions may decrease HbA1c level in patients with T2DM, which would be helpful in reducing the risks of complications and deaths in diabetes patients.

Objective: To understand the seasonal distribution of patient hospitalization due to asthma exacerbation in 7 geographic areas in China. Methods: This was a retrospective study which involved patients hospitalized for asthma exacerbation in 29 hospitals throughout 7 geographic areas in the mainland of China (northeast, north, central, east, south, northwest and southwest). The numbers of asthmatic patients and total inpatients of the respiratory department of each hospital were recorded. The monthly ratio of asthmatic patients to the total inpatients in every area was calculated and compared. Results: During the study period, 6 480 patients were admitted for asthma exacerbation, accounting for 3.14% of all the 206 135 patients admitted to the respiratory departments in the 29 hospitals. The ratio of asthmatic patients to total inpatients in the northeast area (5.61%) was highest, and the ratio in east area was lowest (1.97%). Statistical analysis showed that the difference among different areas was significant (P<0.000 1). In most areas, both the number and proportion of hospitalized asthmatic patients peaked in spring (February-April) and autumn (September-October). In the northeast area, east area and south area, the peaks in spring were more obvious, while in the north area and southwest area, the peaks in autumn were more obvious. In the northwest area the peaks occurred in winter (December-January) and summer (June-August), respectively. The differences in hospitalization due to asthma among different months were significant in the northeast, north, and southwest areas (P<0.005). Conclusion: The number of patients hospitalized for asthma exacerbation fluctuated with season in different areas in China. In most areas, more asthmatic patients were admitted to hospitals in spring and autumn.
