Objective: To assess the implementation and impact of programs carried out by the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases. Methods: Both sociological and epidemiological methods were used to collect qualitative and quantitative data in November and December, 2016 in order to conduct on process and outcome evaluation of the above mentioned objective. In the meantime, case study was also conducted. Results: All the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases were found well implemented across the country, with health education and health promotion, surveillance and safeguard measures in particular. A government-led and inter-sector coordination and communication mechanism had been well established, with more than 16 non-health departments actively involved. 28.7% of the residents living in the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases were aware of the key messages related to chronic diseases. Among the residents, 72.1% of them consumed vegetables and 53.6% consumed fruits daily, with another 86.9% walked at least 10 minutes per day. Over 70% of the patients with hypertension or diabetes reported that they were taken care of by the Community Health Centers, and above 50% of them were under standardized management. Residents, living in the National Demonstration Areas under higher ranking of implementation scores, were more likely to be aware of relevant knowledge on chronic disease control and prevention (OR=6.591, 95%CI: 5.188-8.373), salt reduction (OR=1.352, 95%CI: 1.151-1.589), oil reduction (OR=1.477, 95%CI: 1.249-1.746) and recommendation on physical activities (OR=1.975, 95%CI: 1.623- 2.403). Conclusion: The implementation of programs carried out by the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases had served a local platform for the control and prevention of non-communicable diseases, and thus become an important 'carrier' for chronic disease prevention and control programs in China.

Objective: To investigate the current status of prevalence, treatment, and management on hypertension among Chinese adults from the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases. Methods: We selected a total of 4 000 residents aged ≥18 years for this questionnaire-based survey by multi-stage clustering sampling in 10 National Demonstration Areas between November and December, 2016. Results: There were 3 891 effective questionnaires. The self-reported prevalence of hypertension among aged ≥35 years was 31.47% (1 011/3 213). For the past two weeks, the self-reported treatment of hypertension was 86.75%(877/1 011), with the rates of guidance as 56.87% (575/1 011) on physical activity, 40.95% (414/1 011) on diet, 38.33% (385/1 011) on weight management, and 22.75% (228/1 011) on smoking cessation. For the past 12 months, 74.68% (755/1 011) of the residents aged ≥35 years were under the proper management and 62.12% (628/1 011) of them were under the standardized management programs. The follow-up program lasted for 4 (P(25)-P(75): 4-12) times per year, with 15 (P(25)-P(75): 10-20) minutes per each visit. Hypertensive patients would mainly visit the outpatient clinics (53.51%), followed by home visits (22.91%) and telephone calls (13.64%). Rate of satisfaction on management services was 94.83% (716/755) from the hypertensive patients. Multivariate analysis showed that the rate of self-reported treatment (OR=1.986, 95%CI: 1.222-3.228) and self-reported standardized management (OR=2.204, 95%CI: 1.519-3.199) on hypertension were higher in the Demonstration Areas with higher implementation scores of self-reported non-communicable diseases management. Conclusions: Prevention and management on hypertension in the Demonstration Areas had met the requirement set for the Demonstration Areas during the "12th Five-Year Plan" . Projects on setting up the National Non-communicable Diseases Demonstration Areas had played an active role in promoting the standardized management program on hypertension.

OBJECTIVEFurther studies have been conducted to evaluate the roles of Ngn3 in adult islet maintenance and renewal.

METHODSIslets were isolated from 6 - 8 week old male C57BL/6 mice. After common bile duct cannulation, the pancreas was resected and digested in collagenase V (2.5 mg/ml). Islets were then handpicked and 10 - 12 islets were plated in 60 mm culture dish and cultivated with RPMI-1640, which contained 12.5 mmol/L HEPES, 5.2 mmol/L glucose and 2% fetal bovine serum (FBS). Islet cells were analyzed by immunocytochemistry methods for A6, insulin, glucagon, nestin, Ngn3 and 5-bromo-2'-deoxy-uridine (BrdU).

RESULTSThe results of these studies indicated that less than 15 percent of proliferated islet cells were Ngn3 expressing cells, in which about one third of the Ngn3 positive cells co-expressed A6. The existence of Ngn3 in cultured islet cells is consistent with the results from other's findings both in embryogenesis and adult islet studies. A significant finding of our study is that the existence of A6 and Ngn3 co-expressing cells in the cultured islet. A6 is a marker for identifying bile duct epithelial cell oriented hepatic progenitor cells. Islet-derived A6 cells are possibly born in the adult pancreatic duct and migrate into islets. A6 cells co-express Ngn3 when these cells commit to endocrine lineage within the islets. More interestingly, islet-derived A6 positive cells have the potential to transdifferentiate into hepatic cells.

CONCLUSIONThe presence of Ngn3(+) and A6(+) cells in the cultured islets suggests that the four established islet cell types arise from a common endocrine lineage residing within the adult islets. A6 and Ngn3 are useful markers for understanding intra-islet adult stem cell lineages in our future studies. This approach may allow for significant advances in understanding the IPC proliferation and differentiation, and open the possibility of using intra-islet adult stem cells for diabetes treatment.

Objective: To explore the relationship between male sexual function and daily exposure to bisphenol A (BPA) at a reproductive center in Taiyuan. Methods: Male patients who were seeking treatment of infertility due to problems caused by either of the spouse were selected from the Shanxi reproductive center between September 2014 and April 2015. Information on general characteristics, sexual function and fasting venous blood samples were collected. Total scores of sexual function were evaluated by Delphi expert scoring method. Levels of serum BPA were measured by high-performance liquid chromatography. Data was analyzed by Spearman rank correlation, rank sum test, multivariate logistic regression analysis and χ(2) trend test. Relationship between BPA and sexual function was presented as OR and corresponding 95%CI. Results: Among the 353 participants, 45.0% was defined as sexual dysfunction with low sexual desire (47.3%) as the major reason. BPA was detected in all the 353 patients, with a range of concentration as 0.38-21.93 ng/ml and an average as 5.79 ng/ml. Results from the Spearman rank correlation analysis revealed significant negative correlations between serum BPA and sexual function, sexual desire, erectile ability and ejaculation intensity, while serum BPA was positively correlated with premature ejaculation. According to the four percentile of BPA concentration (ng/ml), the subjects were divided into four groups. Compared with the low concentration group (0.38-3.79 ng/ml), the risk of sexual dysfunction significantly increased in the groups with higher BPA levels. Particularly, in the highest BPA group (8.68-21.93 ng/ml), more obvious effects were seen on sexual dysfunction (OR=1.55, 95%CI:1.00-3.23), reduced sexual desire (OR=4.75, 95%CI: 2.44-9.22), reduced erection ability (OR=2.40, 95%CI: 1.18-4.88), reduced ejaculation intensity (OR=2.53, 95%CI: 1.25-5.16) and premature ejaculation (OR=1.95, 95%CI: 1.02-3.72). Conclusion: Low sexual desire appeared as the main type of male sexual dysfunction, the exposure to higher levels of BPA in daily life might lead to male sexual dysfunction.

Objective: To understand the dynamic variation of BMI and influencing factors among HIV/AIDS patients receiving highly active anti-retroviral therapy (HAART) in Liuzhou, Guangxi Zhuang Autonomous Region (Guangxi). Methods: HIV/AIDS patients receiving HAART for the first time since 1 January 2013 were selected. Data on BMI was analyzed among patients receiving HAART at baseline,6 months and 12 months after treatment. By using the general linear model repeated measures of analysis of variance, BMI dynamic variations and influencing factors were described and analyzed. Results: The average BMI of 2 871 patients at baseline, 6th months and 12th months appeared as (20.65±3.32), (20.87±3.22) and (21.18±3.20), respectively, with differences all statistically significant (F=18.86, P<0.001). BMI were increasing over time with treatments (F=37.25, P<0.001). Main influencing factors were noticed as: age, sex, marital status, baseline data of CD(4)(+)T cells and the WHO classification on clinical stages. Conclusions: Higher proportion of BMI malnutrition counts was seen among patients before receiving HAART in Liuzhou. BMI of the patients that were on HAART seemed being influenced by many factors. It is necessary to select appropriate treatment protocols on different patients so as to improve the nutritional status of the patients.

Objective: To evaluate the association of educational level with anthropometric measurements at different adult stages and their long-term changes in adults who participated in the second re-survey of China Kadoorie Biobank (CKB). Methods: The present study excluded participants who were aged >65 years, with incomplete or extreme measurement values, or with major chronic diseases at baseline survey or re-survey. The weight at age 25 years was self-reported. Body height, body weight and waist circumference at baseline survey (2004-2008) and re-survey (2013-2014) were analyzed. Results: The present study included 3 427 men and 6 320 women. Both body weight and waist circumference (WC) increased with age. From age 25 years to baseline survey (mean age 45.2±6.5), the mean weight change per 5-year was (1.70±2.63) kg for men and (1.27±2.10) kg for women. From baseline survey to re-survey (53.2±6.5), the mean changes per 5-year for body weight were (1.12±2.61) kg for men and (0.90±2.54) kg for women; and that for WC was (3.20±3.79) cm for men and (3.83±3.85) cm for women. Among women, low educational level was consistently associated with higher body mass index (BMI) and WC at age 25 years, baseline survey and re-survey. Among men, low educational level was associated with higher BMI at age 25 years. At baseline survey and re-survey, the educational level in men was not statistically associated with BMI; but men who completed junior or senior high school showed slight higher WC and increase of WC from baseline survey to re-survey than other male participants. Conclusions: Body weight and WC increased with age for both men and women. The associations of educational level with BMI and WC were different between men and women.

Objective: To investigate the association between maternal body height and risk of preterm birth. Methods: A total of 11 311 pregnant women who gave birth of live singletons were recruited from the Healthy Baby Cohort Study in Hubei province, China from September 2012 to October 2014. Finally 11 070 pregnant women were selected as study subjects. Data were collected by using questionnaires, their prenatal care records and medical records. The women were divided into 4 groups according to the quartiles distribution (<158 cm, 158- cm, 160- cm, and >164 cm). Gestational age was estimated according to maternal last menstrual time. Preterm birth was defined as delivering a live singleton infant at 28-37 weeks' gestational age. Logistic regression was used to calculate the odds ratios (OR) and 95% confidence intervals (CI) for the association between body height and preterm birth. Results: Among the 11 070 pregnant women, the incidence of preterm birth was 5.9%. Logistic regression analysis indicated that women in group with body height <158 cm had 46% (OR=1.46, 95%CI: 1.16-1.83) higher risk of giving preterm birth than those in group with body height >164 cm after adjustment for potential confounders. Every 1- cm increase in body height was associated with 3% lower risk of preterm birth (OR=0.97, 95%CI: 0.95-0.99). Conclusion: Shorter body height was a risk factor for preterm birth. It is necessary to strengthen the monitoring in pregnant women with short body height to reduce the risk of preterm birth.

Objective: To investigate the risks of pre-pregnancy overweight, excessive gestational weight gain on macrosomia. Methods: We conducted one hospital-based cohort study, focusing on pregnant women from January 2015. All pregnant women attending to this hospital for maternal check-ups, were included in our cohort and followed to the time of delivery. Data related to general demographic characteristics, pregnancy and health status of those pregnant women, was collected and maternal pre-pregnant BMI and maternal weight gain were calculated. Logistic regression was used to explore the risk difference of pre-pregnancy BMI, excessive gestational weight gain on macrosomia. Results: The overall incidence of macrosomia in our cohort appeared as 6.6% (149/2 243). After adjusting the confounding factors including age and histories on pregnancy, pre-pregnancy overweight/obesity was associated with higher risks of macrosomia (OR=3.12, 95%CI: 1.35-7.22, P=0.008; OR=2.99, 95%CI: 1.17-7.63, P=0.022) when comparing to those with normal pre-pregnancy weight. Cesarean delivery and sex of the offspring were associated with higher risk of macrosomia, while excessive gestational weight gain showed no significant difference (OR=1.41, 95%CI: 0.96-2.09, P=0.084). Our data showed that Macrosomia was statistically associated with gestational weight gain (P=0.002). After controlling parameters as age, history of pregnancy and related complications of the pregnant women, results from the logistic regression showed that women with gestational inadequate weight gain having reduced risks to deliver macrosomia, when compared to those pregnant women with adequate weight gain (OR=0.52, 95%CI: 0.30-0.90, P=0.019). Conclusion: Pre-pregnancy overweight and obesity were on higher risks to macrosomia.

Objective: To investigate the influence of dietary cholesterol intake on gestational diabetes mellitus (GDM), at one year prior to and first and second trimesters of pregnancy. Methods: Between March 2012 and September 2016, the pregnant women from the First Affiliated Hospital of Shanxi Medical University were asked to fill in a set of questionnaires, by which information on general demographic characteristics, diagnosis of GDM and dietary cholesterol intake was collected. Unconditional logistic regression method was used to analyze the influence of dietary cholesterol intake on GDM, at one year prior to and first and second trimesters of pregnancy. The association on dietary cholesterol intake and GDM between age groups was also analyzed. Results: Data on 9 005 subjects, including 1 388 pregnant women with GDM, was collected. When the amount of cholesterol intake was stratified into quartile, results from the unconditional logistic regression showed that dietary cholesterol intake appeared ≥76.50 mg/d, both in the periods of one year prior to and the second trimester of pregnancy. This amount of dietary cholesterol intake would increase the risk of GDM (one year prior to pregnant: OR=1.230, 95%CI: 1.018-1.485; second trimester: OR=1.228, 95%CI:1.014- 1.486). Women who took ≥76.50 mg/d of daily cholesterol during the period of one year prior to, or 46.75-76.50 mg/d during the second trimester of pregnancy, the risks of GDM (OR=4.644, 95%CI: 1.106-19.499) would increase. Women with daily cholesterol intake over 76.50 mg/d during the period of one year prior to or at the second trimester of pregnancy, there appeared a risk on GDM (OR=1.217, 95%CI: 1.012-1.463). When maternal age was divided in two different subgroups and the cholesterol intake level was ≥76.50 mg/d both in the period of one year prior to pregnancy or at the second trimester, the risk of GDM appeared in the subgroup of<35 years old (OR=1.336, 95%CI:1.083-1.647; OR=1.341, 95%CI: 1.087-1.654). However, no significant association was found in the maternal age group of ≥35 years old. Conclusion: High level of dietary cholesterol intake would increase the risk of GDM, both in the period of one year prior to and at the second trimester of pregnancy.

The process of globalization increases the risk of global transmission of infectious diseases, resulting in pressure for country's prevention and control of imported infectious disease. Based on the risk assessment of disease importation and local transmission, a strategy that conducting importation prevention and routine prevention and control before the importation of disease and taking emergency control measures after the importation of disease was developed. In addition, it is important to take part in global infectious disease response action, aid the countries with outbreak or epidemic to actively decrease the risk of disease importation.
