Objective To explore the role of Kupffer cell-expressed Fas ligand(FasL) on acute pancreatitis(AP),and the protective effect of gadolinium chloride(GdCl3),a Kupffer cell inhibitor,on liver injury during AP.Methods Fifty-four ICR mice were randomly assigned into three groups: healthy control group(n=6);AP group(four time points for observation,6 mice each);Gd+AP group(GdCl3 pretreatment group,four time points for observation,6 mice each).AP was induced in mice using cerulein.Liver parenchymal enzymes(AST,ALT and LDH) and amylase(AMY) were assayed using an automatic analyzer.Serum FasL was assayed with ELISA and FasL protein expression in liver was assayed by Western blotting.Results After induction of AP in mice,the serum levels of AST,ALT,LDH,AMY and liver FasL expression were significantly elevated.Serum FasL levels at 4,8,16 and 24h after AP induction were 505.94?36.21,496.60?33.65,476.64?22.66 and 450.75?38.21,respectively,which were significantly higher than those in healthy control group(83.60?7.75,P

Objective To investigate the effect of liver transplantation on hepatitis B associated diseases and the efficiency of prevention and treatment on the re-infection of hepatitis B.Methods The data of 17 patients undergoing liver transplantation were analyzed after treatment of lamivudine and hepatitis B immune globulin (HBIg). Results Of the 17 cases of hepatitis B pretransplantation, 2 cases were positive for HBsAg. Liver function was normal in all patients.Conclusions Liver transplantation is an effective therapy for hepatitis B. Lamivudine and HBIg could effectively prevent and treat the re-infection of hepatitis B after liver transplantation.

Objective To analyze the prevalence of nosocomial infections among inpatients and its influential factors.Methods The retrospective survey was performed by reviewing and analyzing the clinical data of 7788 inpatients in 2004 in Nankai Hospital of Tianjin.Results Totally 250 nosocomial infection cases were identified,which gave a prevalence of 3.21%.The all-year highest prevalence was found in September.Among all the departments,the highest rate,5.20%,occurred in Department of Gynecology.The inpatients aged more than 60-year-old showed higher prevalence than those under 60 years old.The main infection position was lower respiratory tract(41.60%).Concludes The prevalence of nosocomial infections of Nankai Hospital were within the acceptable standard range defined by Ministry of Health,China.Nevertheless,the prevalence would be reduced if measurements for surveillance and control could be properly applied.

Objective To study whether closed reduction and interlocking intramedullary nailing will worsen the injured radial nerve associated with the fracture of humeral shaft.Methods Of the 353 patients with fracture of humeral shaft who received operation from January 2002 to January 2005,63 ones were complicated with preoperative injury to their radial nerve.A retrospective analysis was done of their physical examination records, operative records,X-ray films and results of the treatment.Eleven cases were treated with closed reduction and interlocking intramedullary nailing,and 52 cases with open reduction and internal fixation of plates and screws fol- lowed by exploration to the radial nerve.Chisquare test of PEMS 3.1 system was adopted to analyze the clinical data. Results The radial nerve was embedded by the fracture ends in nine cases(17.3%)of the 52 cases,and con- tused in the other 43 ones.In the 63 cases,The injured nerves recovered spontaneously 2 to 12 weeks postoperatively except in twn cases.All the eases got bony union 3 to 4 months after operation.Closed reduction and interlocking intramedullary nailing has hardly more harmful effects on the injured radial nerve assoeiated with the fracture of humeral shaft than open reduction and internal fixation of plates and screws followed by neural exploration.Con- clusion Closed reduction and interlocking intramedullary nailing is fit for the freatment of fractures of humeral shaft with radial nerve injury.
