Objective To explore the correlations of expressions of gastric mucosa water channel aquaporin AQP3 and AQP4 and different gastritis types. Methods The gastric mucosa was mounted under gastroscope. The types of gastric mucosa pathology and activity were tested by the common pathohistology. The expressions of AQP3 and AQP4 were determined by immunohistology. Results The expressions of AQP3 and AQP4 of chronic superficial gastritis were significantly higher than those in the non-gastritis group and chronic atrophic gastritis group (P < 0.01), especially in the activity period of chronic superficial gastritis. The expressions of AQP3 and AQP4 of chronic atrophic gastritis group were reduced when compared to those in the non-gastritis group, in spite of no statistical differences between them. While compared to the non-gastritis group , the expression of AQP3 of chronic atrophic gastritis group during the active stage was remarkably decreased (P < 0.05). Conclusion The expressions of AQP3 and AQP4 of gastric mucosa in chronic gastritis in various pathological types are different. AQP3 and AQP4 may be the targeted point , which could be used for the differential diagnosis and treatment of chronic gastritis of different pathological types.

Objective To investigate the changes of serum angiopoietin-like protein 3 (Angptl3) and adiponectin levels in patients with metabolic syndrome (MS) in order to understand their association with the MS. Methods Serum Angptl3 and adiponectin levels were measured by sandwich ELISA in a group of 111 patients with MS and 152 normal controls. Results Serum adiponectin was lower in the MS patients than in the control subjects [4.22(1.01-23.29) μg/mL vs. 5.41(0.97-22.27) μg/mL, P<0.05]. With regard to serum Angptl3, there was no significant difference between the 2 groups(P>0.05). Serum adiponectin was correlated to Angptl3 and high density lipoprotein-cholesterol (HDL-C)(P<0.001) and negatively correlated to body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), triglyceride (TG), fasting plasma glucose (FBG), fasting insulin (FINS) and homeostatic model assessment method-insulin resistance (HOMA-IR) (P<0.001). Serum Angptl3 was positively correlated with adiponectin (P<0.001). Serum adiponectin was found to be independently positive determinant for Angptl3 concentrations (b′=0.256, P<0.001). Adiponectin was inversely correlated with TG and HOMA-IR (b′=-0.234, -0.145, P<0.001). Conclusion Adiponectin is decreased in MS patients and may be correlated to Angptl3.

Objective To determine the changes in the prevalence of type 2 diabetes mellitus and prediabetes in residents aged over 20 years in Shandong coastal areas during years 2004-2014. Methods A random stratified cluster sampling was conducted, and 3 944 inhabitants were investigated in Qingdao, Yantai, Weihai, and Rizhao regions. Results (1)The standardized rate of diabetes mellitus prevalence was 10.36% in 2014, increased by 2.38% as compared with 2004 and 0.85% as compared with 2009 (P<0.05). There were 341 newly diagnosed diabetes mellitus patients, accounting for 57.4% of the diabetes mellitus patients, increased by 6.09% as compared with 2004 and decreased by 4.11% as compared with 2009 (P<0.05). The standardized rate of prediabetes was 12.47% in 2014, increased by 2.63% as compared with 2004 and 0.61% as compared with 2009 (P<0.05). (2) The prevalence of diabetes mellitus and impaired glucose regulation in individuals aged under 50 years in 2014 was significantly higher than that in 2004, but lower than that in 2009 (P<0.05). (3) Compared with 2004 and 2009, the levels of diastolic blood pressure, total cholesterol, low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol in subjects with prediabetes and diabetes mellitus increased significantly in 2014 (all P<0.05). The levels of serum uric acid in subjects with prediabetes and diabetes mellitus decreased significantly in 2014 (P<0.05). (4) The logistic regression analysis showed that the age, body mass index, waist-hip ratio, triglyceride, LDL-C, systolic blood pressure, and diabetic family history were the risk factors for abnormal glucose regulation, while total cholesterol was the protective factor. Conclusions The prevalence of diabetes mellitus and prediabetes increased during 10 years (2004-2014), but the growth rate dropped precipitously during last five years as compared with the first five years. The age of diabetes mellitus onset is getting older in residents of Shandong coastal area, especially in females. Aging, overweight, hypertension, lipid disorders, and diabetic family history were the risk factors of diabetes mellitus.
