Objective:To observe the changes of serum adiponectin level in patients with non-alcoholic fatty liver disease (NAFLD),and to study the correlation between the serum level of adiponectin and NAFLD. Methods: A total of 110 patients with NAFLD who were hospitalized from Feb. 2006 to Mar. 2008 were included in this study. The patients were divided into non-alcoholic steatohepatitis (NASH) group (n=52,group 1) and simple fatty liver group (n=58,group 2). Fifty-four healthy volunteers were taken as normal control (group 3). The height,weight,and body mass index (BMI) were measured in all groups. The fasting blood samples were obtained to examine serum adiponectin,TC,TG,HDL-C and LDL-C. Stepwise regression method was used to analyze relationship between the serum level of adiponectin and NAFLD. Results: The serum adiponectin and HDL-C levels in group 1 and group 2 were significantly lower than those in group 3 (P

Objective:To detect precancerous lesions of gastric cancer and biopsy tissue vascular endothelial growth factor (VEGF)and mutant p53 gene(mtp53)expression,to explore the development of clinical significance of VEGF and mutant p53 gene in gastric cancer.Methods:19 cases by endoscopic biopsies of normal gastric tissues,22 cases of intestinal metaplasia,47 cases of gastro-intestinal mucosal dysplasia, 54 cases of gastric cancer samples by immunohistochemical staining to detect the expression levels of VEGF and mtp53′s.Results: The expression levels of VEGF, mtp53 in normal gastric mucosa, intestinal metaplasia, dysplasia, and gradually increased gastric cancer was the law.mtp53 of VEGF expression in gastric carcinoma and compared with normal gastric tissue,intestinal metaplasia was significantly higher(P<0.05),but with atypical hyperplasia was no significant difference(P>0.05). Conclusion: The abnormal expression of VEGF and mutant p53 may be related to the degree of deterioration of the stomach tissue lesions related.
