To investigate the role of autophagy in MnCl2-induced apoptosis in human bronchial epithelial 16HBE cells.Cell proliferation was measured by MTT assay. Mitochondrial membrane potential (MMP) and apoptosis were measured by flow cytometry. Autophagic vacuoles were detected by fluorescence microscopy. Cellular levels of apoptosis and autophagy-related proteins were measured by western blotting.16HBE cell proliferation was inhibited by MnCl2 in a dose- and time-dependent manner. MnCl2-induced 16HBE cell growth inhibition was related to MMP depolarization prior to the induction of apoptosis. Our data revealed that MnCl2-induced apoptosis in 16HBE cells was mediated by decreased expression of Bcl-2 and increased levels of cleaved caspase-3. It was observed that when we exposed 16HBE cells to MnCl2 in a dose-dependent manner, the formation of autophagic vacuoles and the levels of LC-3B-II were elevated. RNA interference of LC3B in these MnCl2-exposed cells demonstrated that MMP loss and apoptosis were enhanced. Additionally, the pan-caspase inhibitor Z-VAD-FMK increased the cellular levels of Bcl-2 and decreased apoptosis, but did not affect the cellular levels of LC3B in MnCl2-treated 16HBE cells.MnCl2 dose- and time-dependently inhibits 16HBE cell proliferation and induces MMP loss and apoptosis. Autophagy acts in a protective role against MnCl2-induced apoptosis in 16HBE cells.

OBJECTIVE Our objective was to determine the secular trend in prevalence of type 2 diabetes in Shanghai, China. RESEARCH DESIGN AND METHODS Two consecutive population-based surveys for type 2 diabetes were conducted in randomly selected adults aged 35–74 years in Shanghai in 2002–2003 (n = 12,329) and in 2009 (n = 7,423). Diagnosed type 2 diabetes was determined based on self-report, whereas those undiagnosed were identified by measured fasting and postload glucose according to 2009 American Diabetes Association criteria. RESULTS Age-standardized prevalence of diagnosed and undiagnosed type 2 diabetes increased from 5.1 and 4.6% in 2002–2003 to 7.4 and 5.2% in 2009. The prevalence of type 2 diabetes increased with age and was higher among men and in urban residents in both surveys (P < 0.001). Between the two surveys, the increase in the prevalence was more evident in the rural population (P < 0.001) and appeared more rapid in younger birth cohorts (P < 0.05). CONCLUSIONS Our results suggest that Shanghai has experienced an increasing burden of type 2 diabetes.

To study the associations of pedestrian injuries with age, income and educational level in Shanghai and to analyze the relative disease burden.Information on pedestrian-related cases and deaths were collected from 494 hospitals and mortality registry systems from 1992 to 2010, and a multistage cluster sampling survey conducted in 2006. Logistic regression model was used in the analyses.The age group of 5-9 had the highest mortality and morbidity among children. Mortality increased obviously among those aged 60 or above. Individuals with an educational level under the primary school and with the lower family average income were more likely to suffer pedestrian-related injuries. Multivariate Logistic analysis demonstrated that lower income and lower educational level increased the risk of pedestrian injuries with the odds ratio of 1.40 (95% CI: 1.15-1.71) and 1.70 (95% CI: 1.20-2-40), respectively. About 13.54% of the share of GDP for the healthcare, social security and welfare industries in Shanghai was occupied by the burden of pedestrian-related injuries in 2006.Pedestrian-related injury has inverse association with victims' income and educational level. Children of 5-9 years old and adults over 60 with lower educational level and lower monthly income are the target persons to be intervened.

To investigate the risk factors and behavior features related to chronic diseases among adults in Shanghai.A total of 15 516 subjects aged over 18 years old were selected from the investigation project on chronic diseases and relevant risk factors in Shanghai in 2010. Questionnaire were used to investigate the general information of the subjects, such as behavior features as smoking, drinking, diet, physical activity as well as the prevalence and control of chronic diseases as hypertension and diabetes. The physical examination included height, weight, waist circumference, blood pressure, blood glucose and blood lipids.Being preprocessed by complex weighting method, the data showed that the overweight rate of Shanghai adults aged above 18 was 32.4% (5288), separately 32.2% (2506) and 32.5% (2782) (χ(2) = 0.10, P = 0.844) in urban and rural areas; the obesity rate was 8.8% (1538), separately 8.7% (738) and 8.8% (800) (χ(2) = 0.06, P = 0.901) in urban and rural areas. The overweight rate was separately 36.0% (2888) in males and 28.6% (2400) in females (χ(2) = 96.61, P0.01); while the obesity rate was separately 8.7% (745) in males and 8.9% (793) in females (χ(2) = 0.06, P = 0.851). Abdominal obesity rate was 44.3% (7419), separately 47.8% (3892) in males and 40.6% (3527) in females (χ(2) = 81.23, P0.01), 46.5% (3703) in urban areas and 42.6% (3716) in rural areas (χ(2) = 24.37, P = 0.069). Current smoking rate was 25.0% (3813), separately 48.4% (3722) and 1.2% (91) in males and females (χ(2) = 4572.06, P0.01); 23.6% (1609) and 26.0% (2204) in urban and rural areas (χ(2) = 11.92, P = 0.018). The regular smoking rate was 22.1% (3402). The rate of having the habit of drinking at least once a month in males was 39.5% (3102), separately 35.1% (1262) and 42.7% (1840) in urban and rural areas (χ(2) = 45.98, P = 0.012). The rate of drinking almost every day was 16.3% (1380), and the percentage of excessive alcohol consumption was 28.9% (2483). The percentage in group of subjects aging between 45-59 years old was 38.5% (1191), which was higher than that in any other groups (22.8% (641) in group aging 18-44 years old and 22.9% (651) in group aging ≥ 60 years old) (χ(2) = 241.38, P0.01). The percentage of over-drinking in rural area was higher than that in urban area, which was 33.5% (1578) and 22.8% (905) respectively (χ(2) = 117.12, P0.01). The percentage of once over-drinking was 11.3% (903). It was higher in group aging between 45-49 years old (15.3% (461)) than in other groups (9.0% (222) in group aging 18-44 years old and 8.2% (220) in group aging ≥ 60 years old) (χ(2) = 78.21, P0.01). It was also higher in rural area (13.5% (605)) than in urban area (8.3% (298)) (χ(2) = 51.74, P0.01). There were 75.0% (11 993) of the Shanghai adults never took physical activity. And the most important problems in dietary habit were insufficient intake of dairy products (98.0%, 15 218), vegetables (53.0%, 7864) and fruits (84.6%, 13 372), excess consumption of sodium (52.0%, 8257) and oil (51.7%, 7884).The risk factors of chronic diseases were highly prevalent in Shanghai. The prevalence of risk factors as overweight or obesity, lack of physical activity, smoking, over-drinking and unhealthy dietary habits were higher among adults living in suburban areas than those living in urban areas; the prevalence was also higher among the young adults than that among the elderly people, higher among males than that among females.

To investigate whether cadmium-induced oxidative stress in the kidney is influenced by zinc and selenium.Five groups of rats were maintained: (A) Cd (CdCl2, 400 micrograms.kg-1.day-1 intraperitoneal injection); (B) Cd + Zn (ZnCl2, 20 mg.kg-1.day-1 hypodermic injection); (C) Cd + Se (Na2SeO3, 350 micrograms.kg-1.day-1 via a stomach tube); (D) Cd + Zn + Se; (E) treated with physiological saline as a sham-handled control. The rats were given treatment for a period of 4 weeks. The activities of superoxide dismutase (SOD), glutathione peroxidase (GH-Px), catalase (CAT), and the level of malondialdehyde (MDA) in the kidney tissue were measured to assess the oxidative stress. Urinary lactate dehydrogenase (LDH) activity was used as an indicator of tubular cell damage caused by lipid peroxidation.In group C and D, activities of SOD (110.5 +/- 5.2, 126.8 +/- 7.0; P0.05) and GSH-Px (85.7 +/- 4.9, 94.6 +/- 7.3; P0.05) were higher than those in group A (84.7 +/- 3.3; 56.9 +/- 3.8); and in group B, only the activity of GSH-Px (80.0 +/- 4.3, P0.01) increased in comparison with that in group A (56.9 +/- 3.8). Significant increase of MDA (P0.05) was seen in group B (31.1 +/- 4.7) and C (35.0 +/- 4.1) when compared with control values (17.2 +/- 1.8). No difference was found in the level of MDA between group D (18.9 +/- 2.6) and control. The activity of LDH in urine of control group (0.06 +/- 0.02) was lower than that of group A (0.46 +/- 0.19, P0.05), B (0.10 +/- 0.05, P0.05) and C (0.14 +/- 0.07, P0.05), and there was no significant change between control (0.06 +/- 0.02) and group D (0.08 +/- 0.02).Zinc or selenium could partially alleviate the oxidative stress induced by cadmium in kidney, but administration cadmium in combination with zinc and selenium efficiently protects kidney from cadmium-induced oxidative damage.

Background: To provide a comprehensive overview of temporal trends in cancer incidence during 1973-2010 in urban Shanghai.Methods: The estimated annual percent changes (EAPCs) for the whole period and for the time segments in age-standardized incidence rates (ASR) were evaluated with Joinpoint analysis. Age-period-cohort (APC) models were modeled to examine the effects of age, period and birth cohort on cancer incidence.Results: The overall ASR decreased slightly and significantly in males (EAPC of -0.41) but increased significantly in females (EAPC of 0.57) during 1973-2010 in urban Shanghai. The incidence trend was not linear and varied by time segments. During the most recent 10 years (2001-2010), the ASR in males decreased by 1.65% per year and stabilized in females. Incidence rates continued to decline during 1973-2010 for esophagus, stomach, and liver cancer in both sexes, as well as male lung cancer and cervix cancer. It should be noted that it was the first time to document a significant decline in lung cancer incidence among males during 1973-2010 with EAPC of -0.58%, and a notable upward for cervix cancer since 1996 with EAPC of 8.94%. Unfavorable trends in incidence were observed for the most common cancer sites in the 38 years period: colorectum, gallbladder & biliary tract, pancreas, kidney, bladder, brain & central nervous system (CNS), thyroid, non-Hodgkin's lymphoma (NHL), prostate, female breast, corpus uteri, and ovary. APC analysis showed age, period and birth cohort yielded different effects by cancer sites.Conclusions: The observed trends primarily reflect dramatic changes in socioeconomic development and lifestyles in urban Shanghai over the past four decades.

Transparent zinc oxide (ZnO) films were prepared on ZnWO4 crystal by sol-gel technique. Surface morphology of ZnO films were observed with optical mi croscope. The results of show that ZnO films are formed in three different stage s from nucleation on surface, grain growth to island formation. Because ZnO crys tal nucleus were grown under non_equilibrium condition, it is inevitable that de ndrite growth, fractal growth and spinodal decomposition phenomenon are involved in the growing process.

Abstract: Fe3O4 thin films have been grown on ITO glass substrates using an electrodeposition technique. The properties of the films can be tuned by changing the electric potential within −1.00V to −1.22V. Preferred crystalline orientation along 〈511〉 arises in the samples prepared with the potentials of −1.06V to −1.08V. An apparent decrease of the in-plane coercivity is found in these films with preferred orientation. A simple model considering the interplay of shape anisotropy and magnetocrystalline anisotropy, which leads to a weaker effective plane anisotropy in the oriented films, is given to explain the decrease of coercivity.
