ABSTRACT
BACKGROUND/OBJECTIVES@#This study examined the relationship between famine exposure in early life and the risk of type 2 diabetes in adulthood during the 1959–1961 Chinese Famine. @*SUBJECTS/METHODS@#A total of 3,418 individuals aged 35–74 years free of diabetes from two studies in 2006 and 2009 were followed up prospectively in 2009 and 2012, respectively. Famine exposure was classified as unexposed (individuals born in 1962–1978), fetal exposed (individuals born in 1959–1961), child exposed (individuals born in 1949–1958), and adolescent/adult exposed (born in 1931–1948). A logistic regression model was used to assess the relationship between famine exposure and diabetes after adjustment for potential covariates. @*RESULTS@#During a three-year follow-up, the age-adjusted incidence rates of type 2 diabetes were 5.7%, 14.5%, 12.7%, and 17.8% in unexposed, fetal-exposed, child-exposed, and adolescent/adult-exposed groups, respectively (P < 0.01). Relative to the unexposed group, the relative risks (95% confidence interval) for diabetes were 2.15 (1.29–3.60), 1.53 (0.93– 2.51), and 1.65 (0.75–3.63) in the fetal-exposed, child-exposed, and adolescent/adult-exposed groups, after controlling for potential covariates. The interactions between famine exposure and obesity, education level, and family history of diabetes were not observed, except for the urbanization type. Individuals living in rural areas with fetal and childhood famine exposure were at a higher risk of type 2 diabetes, with relative risks of 8.79 (1.82–42.54) and 2.33 (1.17–4.65), respectively. @*CONCLUSIONS@#These findings indicate that famine exposure in early life is an independent predictor of type 2 diabetes, particularly in women. Early identification and intervention may help prevent diabetes in later life.
ABSTRACT
<p><b>OBJECTIVE</b>Since the incidence rates and risk factor for type 2 diabetes in Chinese populations had not been well known, the aim of this study was to evaluate the impact of weight change and other risk factors on incident type 2 diabetes in Qingdao, China.</p><p><b>METHODS</b>A prospective population-based cohort study was carried out, based on subjects aged 35-74 years who participated in the 'Qingdao Diabetes Survey' in 2006. Subjects were free of diabetes at baseline. A total of 1 294 subjects attended the follow up survey between 2009 and 2011. The diagnostic criteria for Diabetes was classified according to both the World Health Organization and the International Diabetes Federation 2006. A logistic regression was built using the backward stepwise selection to assess the effects of risk factors on the incident type 2 diabetes.</p><p><b>RESULTS</b>During a 4-year follow up period, 120 cases with incident type 2 diabetes were identified, with cumulative incidence of diabetes as 11.8% . Participants who developed type 2 diabetes were significantly older, having significantly higher age-adjusted BMI/waist circumference/systolic blood pressure and total cholesterol, than those subjects who remained non-diabetic both in urban and rural areas. Among individuals with no diabetes at the baseline, factors as age, living in the rural areas, baseline BMI and weight change had all independently contributed to the development of diabetes. The multivariate adjusted relative risks (95%CIs) related to the incidence of diabetes were 1.45 (1.13-1.87), 1.93 (1.12-3.34), 1.46 (1.05-2.03) and 1.49 (1.18-1.88), respectively, for a one standard deviation increase in continuous variables. Compared with the reference group of non-obese and with stable weight, factor as weight loss >5% and BMI <28 kg/m² were independently associated with a 67% (RR = 0.33, 95% CI: 0.11-0.97)reduction in the risk of type 2 diabetes, while BMI >28 kg/m² could increase the risk across the levels of weight change. Similar trends were observed in higher waist and weight gain at baseline.</p><p><b>CONCLUSION</b>This study confirmed the critical importance of obesity in the development of type 2 diabetes. Baseline BMI and weight gain appeared independent predictors on type 2 diabetes.</p>

Objective To review the experience in the management of gastric cancer with liver cirrhosis and portal hypertension.Method A retrospective analysis was made in 35 gastric cancer cases with liver cirrhosis and portal hypertension admitted into our hospital from January 2000 through June 2009.Result There were no intraoperative death in this group.Postoperative ascites occurred in 19 patients,anastomotic leakage in one case,anastomotic bleeding in 2 cases,wound bleeding in 2 cases,intraabdominal infection in 17 cases (of which combined fungal infection in 4 patients),incision infection in one patient and chylous leakage in one case.The morbidity rate was 71%.Four patients died during hospitalization including multiple organ dysfunction syndrome in 2 cases,with mortality rate of 11%. Conclusion In order to reduce the incidence of mortality and complications,we should complete preoperative evaluation,correct perioperative management,guide surgery with damage control concept,follow individualized principles and emphasize on preventive devascularization.
ABSTRACT
Objective To compare the demographic and anthropometric characteristics of IFH,IPH and CH in a Chinese newly diagnosed diabetes population and to evaluate the metabolic profiles of insulin secretion and insulin sensitivity associated with subcategories of newly diagnosed type 2 diabetes.Methods From Mar.2005 to June 2002,in Qingdao 335 patients with newly diagnosed diabetes were classified into three groups:IFH(n=67),IPH(n=92),and CH(n=176).Meanwhile,411(191males)subjects with age-sex matched were selected as control group. Homeostasis model assessment(HOMA-IR)and LIGUANGWEI index(IAI)were applied to assess the status of insulin resistance.Homeostasis model assessment(HOMA-B)and I_0/G_0 were applied to assess the basic function of islet B cell,and I_ 120 /G_ 120 was applied to assess the postload function of islet B cell. Results HOMA-IR increased and IAI decreased significantly in CH group than in IFH and IPH group(P
