Objective To investigate the relationship of peroxisome proliferator activated receptor gamma ( PPAR?)C161T gene polymorphism with related diseases of metabolic syndrome. To disscuss the mechanism of the elderly diseases from gene level and the relation between the gene polymorphism and lipid metabolism. Methods Three hundred seventy one non-sibship subjects of Han nationality were investigated in this study, including 69 old healthy subjects, 302 elderly cases diagnosed as metabolic syndrome. PPAR? C161T gene polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphism, and radioimmunoassay was used to detect serum insulin. The insulin resistance was obtained from homeostasis model assessment (HOMA), and blood glucose, blood lipoprotein, height, weight and so on were tested. The frequencies of PPAR? C161T genotypes and the allele were compared with the clinical data. Results (1) In the groups of old normal health and metabolic syndrome, "T" allele frequency was 0.217,0.201, and "C" allele frequency was 0.783, 0.798 . There was no significant difference between the groups. (2)The triglyceride in CC genotypes of the metabolic syndrome was significantly higher than that in "T" allele carriers. Conclusions (1) The distributing trend of PPAR ? C161T gene polymorphism of the Han nationality in Wuhan in the elderly normal healthy group was in accord with that in the group of the elderly metabolic syndrome. (2) PPAR ? C161T substitution can influence metabolic syndrome, especially in liporprotain metabolism. "T" allele is associated with lower level of triglyceride.

The experience in diagnosis and treatment of bleeding complications in severe acute pancreatitis (SAP) by transcatheter arterial embolization was summarized. The clinical data of 19 SAP patients complicated with intra-abdominal bleeding in our hospital from Jan. 2000 to Jan. 2003 were analyzed retrospectively and the therapeutic outcome of TAE was evaluated statistically. The results showed that the short-term successful rate of hemostasis by TAE was 89.5% (17/19), the incidence of re-bleeding after TAE was 36.8% (7/19) and the successful rate of hemostatis by second TAE was 71.4% (5/7). It was concluded that the intra-abdominal bleeding in SAP was mainly caused by the rupture of erosive/infected pseudoaneurysm. Mostly, the broken vessels were splenic artery and gastroduodenal artery; In terms of emergence hemostatis, TAE is the most effective method. Surgical hemostasis is necessary if hemostasis by TAE is failed or re-bleeding occurs after TAE.

The proliferation and differentiation of pancreatic duct epithelial cells in remnant pancreas during regeneration after partial pancreatectomy in rats were studied, and the source of pancreatic stem cells was characterized. Partial (90 %) pancreatectomy was performed on 4- to 5-week-old Sprague-Dawley rats, and different duct epithelial cells and acinar cells were detected by immunohistrochemical stain method and scored using 5-bromo-2'-deoxyuridine (BrdU) labeling index (LI) at various time points after partial pancreatectomy. It was found that at 24 h after partial pancreatectomy proliferation started in the main, large and small duct cells, and persisted in small duct cells to day 5. There was significant difference between the experimental group and the control group (P<0.001). Acinar cells positive for BrdU were greatly increased and reached the peak LI on day 5. The destroyed lobular architecture almost totally recovered on day 7, and the newly islet cells appeared around the pancreatic ducts. These results suggest that regeneration after partial pancreatectomy is involved in proliferation and differentiation of pancreatic stem cells, and pancreatic stem cells may locate in the pancreatic ductules.
