Objective To explore the changes of colon motility of the rats in multiple organ dysfunction syndrome (MODS) induced bacterial peritonitis and the effects of IL-6, TNF-? and induce nitricoxide synthase (iNOS) on colon motility. Methods Wistar rats were divided into two groups, which were the control group and the MODS group. The number of stool, the amplitude changes of circular smooth muscle strip, the length of smooth muscle cell, and the changes of serum NO in two groups were observed. The expressions of IL-6, TNF-? and iNOS protein and IL-6 mRNA, TNF-? mRNA and iNOS mRNA in distal colon were investigated by using immunohistochemical methods and RT-PCR. Results The numbers of stool and the amplitude in the MODS group were lower than those of the control group (P

Based on collecting, arranging, analyzing the literature, the most widely used assessment tools in caring behavior, caring ability and nursing caring characters were introduced. The problems were found out from its application at home and abroad. The aim was to provide the reference that developing and revising the assessment tools of nurses′humanistic that fit for the Chinese local culture.

Objective To evaluate if continuous hemihepatic inflow occlusion(HH)during hepatectomy can be as safe and effective as intermittent total hepatic inflow occlusion(TH)in reducing blood loss during hepatectomy.Methods From November 2001 to March 2006.eighty patients undergoing liver resections were included in a prospective randomized study comparning the intra-and postoperative course underTH(n=40)or HH(n=40).TH was performed with periods of 20 minutes of occlusion and 5 minutes of releasing,while HH with continuous occlusion.The surface area of liver transection was measured and blood loss was calculated.The amount of blood loss,levels of alanine aminotransferuse (ALT)and aspartate aminotransferase(AST),and postoperative course were recorded. Results The total ischemic time of the HH groups was longer than in the TH group[(42±13)min,(31±13)min,P=0.37],and the operative time in the HH group was longer than in the TH group[(236 ±49)min,(204±38)min,P=0.02 ].No signincant difierenee was found between HH and TH group in blood loss during liver parenchyma transection[(500 ±269)ml,(416 ±235)ml,P=0.14]and in the changes of ALT and AST on the first postoperative day[ALT:(677±572)IU/L,(577 ±327)IU/L,P=0.12;AST:(591 ±468)IU/L,(512±301)IU/L,P=0.66].There were no difierences on postoperative morbidity between the two groups(22.5%versus 20.0%,P=0.35).Conclusion The technique of continuous hemihepatic inflow occlusion is as safe and effective as intermittent total hepatic inflow occlusion.

Objective To investigate the clinical effects of liver transplantation including living related liver transplantation for Caroli's disease (CD). Methods Seven consecutive patients with diffused type of Caroli's disease had undergone liver transplantation (LT) from September 1999 to February 2007 in our single center. The clinical characteristics and survival of these patients were retrospectively reviewed. Results All 7 patients were diagnosed as Caroli's disease with diffused type which manifested recurrent cholangitis in clinical symptoms. Among them, 4 were female and 3 male.The mean age was 16 years old (ranging from 10 to 31 years old). Six patients were subjected to conservative therapy and only one patient had previously undergone cholecystectomy and T tube drainage before transplantation. In types of surgery, 4 patients accepted split liver transplantation with right liver lobe, two got whole liver transplantation and only one underwent living related liver transplantation. In two patients venovenous bypass was done during the operation. The mean duration of surgery was 9. 1 h. Post-transplant complications included pulmonary infection (3 cases), acute rejection (2 cases), pleural effusion (2 cases) and biliary leakage in the split section of donor liver (1 case). One patient died within 19 days caused by acute renal failure and multiple organs dysfunction.The rest six patients are alive without any signs of recurrence of protopathy and the longest survival time is 7 years. Conclusion Liver transplantation is a valuable treatment to Caroli's disease with diffused type. Due to the organ shortage, living related liver transplantation may own identical effects on LT.

Objective To observe changes of hepatic hemodynamics and hepatic functional reserve after splenectomy and periesophagogastric devascularization. Methods From July 2006 to August 2007, thirty patients with portal hypertension caused by hepatitis B cirrhosis underwent splenectomy and periesophagogastric devascuiarization. The PVPG (portal venous pressure gradient) was measured by inductor continually during operation. The HAF (hepatic artery flow), PVF (portal venours flow) and hepatic arterial RI(resistant index) were measured with Doppler sonography. The EHBF(effective hepatic blood flow) and ICGR15 (indocyaninegreen retention rate at 15 minutes) were obtained respectively by indocyaninegreen clearance test before and after the operation. Results PVPG after laparotomy (19±4) mm Hg, ligating the splenic artery(14±4) mm Hg, splenectomy(14±3)mm Hg and periesophagogastric devascularization (12±4) mm Hg showed a tendency to decrease progressively. The PVF decreased [from (42±14) ml/s to (16±8) ml/s] and HAF increased in compensation after operation. The EHBF increased [from (0.48±0.10) L/min to (0.56±0.10) L/min], and the ICGR15 decreased (from 23%±8% to 18%±4%) postoperatively. Conclusion After splenectomy and periesophagogastric devascularization, the hepatic functional reserve improves at least in a short term notwithstanding the decrease of PVPG and PVF.

Objective To evaluate the suitability of reported standard liver volume formulae for Chinese adults based on the practice of 216 cases of living donor liver transplantation in our transplantation center. Methods The graft volume was preoperatively estimated in 179 adult-to-adult right liver living donors by two methods: first, the radiological right liver volume by computed tomography (CT) and second,calculated graft volume obtained by reported standard liver volume formula and the percentage of the right liver volume ( given by CT). Both results were compared to the actual graft volume measured during surgery.Results The mean percentage of right liver volume was 55.4% (SD 5.41%). The results of Urata、Heinemann、Vauthey、 Lee、 Yoshizumi formula were significantly larger than the actual right liver volume (P ＜0. 01 ). The result of Sheung-tat Fan was less than the actual right liver volume, there was statistical ESLV =334. 024 + 11. 508 × BW, is most suitable to estimate adult Chinese donor's right liver volume.

Objective To explore the indications for liver transplantation among patients with hepatolithiasis.Methods Data from 1 431 consecutive patients with hepatolithiasis who underwent surgical treatment from January 2000 to December 2006 were retrospectively collected for analysis.Surgical procedures included T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones,hepatectomy,cholangiojejunostomy,and liver transplantation.Results Nine hundred and sixty-one patients who had a stone located in the left or right intrahepatic duct underwent hepatectomy or T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones.The rate of residual stones was 7.5%(72/961).Four hundred and seventy patients who had a stone located in the bilateral intrahepatic ducts underwent surgical procedures other than liver transplantation;the rate of residual stones was 21.7%(102/470).Only 15 patients with hepatolithiasis underwent liver transplantation;they all survived.According to the degree of biliary cirrhosis,recipients were divided into 2 groups: a group with biliary decompensated cirrhosis(n=7),or group with biliary compensated cirrhosis or noncirrhosis group(n=8).There were significant differences in operative times,transfusion volumes and blood losses between 2 groups(P
