Several unusual manifestations such as white bile draining in common bile duct (14 cases) and casual massive bleeding (2 cases ) during and following hepatobiliary and pancreatic operations is reported. These manifestations were in fact signs of hepatic insufficiency. The manners of manifestations of hepatic insufficiency and their treatment are discussed, with a stress that liver-protective treatment and nutritional support are the fundamental modalities.
Objective To investigate the effects and mechanisms of bile on small intestine mucosal barrier.Methods Fifty Wistar rats were assinged into 3 groups randomly: obstructive jaundice (OJ) group （n=20）, biliary external drainage group （n=20） and control group （n=10）. Ten days after operation, the plasma endotoxin level was determinated, the terminal ileum mucosas was obtained to be morphologically measured by light microscope, and immunohistochemistry and Western blot were uesd to examine the expressions of tight junction proteins zona occludens-1 (ZO-1) and occludin in the mucosas. Results Atrophy significantly appeared in the distal ileum mucosas in OJ group. Compared with control group, the intestinal villus height, mucosa thickness and crypt depth in OJ group were obviously decreased 27.8%, 21.7%, and 25.4% (P=0.001, 0.001, 0.040). There were no differences between external drainage group and control group (P=0.050, 0.070, 0.080); While the values of external drainage group were significantly higher than those in OJ group (all P=0.001). The level of plasma endotoxin was up to (1.49±0.27) EU/ml in OJ group compared with control group 〔（0.27±0.09） EU/ml〕, P=0.001. In external drainage group, the value was （0.91±0.25） EU/ml, which was obviously higher than that in control group and lower than that in OJ group （all P=0.001）. Immunohistochemical study showed b positive expression of ZO-1 dropped from 7/10 in the control group to 6/20 in OJ group （P=0.040）, occludin expression was 8/10 in control group and 7/20 in OJ Group （P=0.020）; expressions of them in external drainage group 〔8/20 （P=0.100,0.210） and 9/20 （P=0.060, 0.200）〕 displayed no significant differences compared with the other twogroups. Quantitative testing of Western blot showed the expressions of ZO-1 and occludin in OJ group were significantly lower than those in control group (P=0.001, 0.010), the values in external drainage group were higher than those in OJ group （P=0.005, 0.014）. The expression of ZO-1 was lower in external drainage group than that in control group (P=0.001), and there was no significant difference of occludin between the two groups (P=0.062）. Conclusion Lack of intestinal bile will undermine the intestinal tight junction protein composition, and make intestinal mucosal barrier impaired. The intestinal barrier more severely injured when biliary tract obstructs because of multiple factors. Bile plays an important role in the maintenance of intestinal mucosal barrier.
To evaluate the effects of different pressure and duration of autologous bile perfusion into dog’s pancreatic duct on the severity of induced acute pancreatitis. Thirty mongrel dogs were divided into five groups, with each group consisting of six dogs. Histological changes of pancreas were observed. Results: Histological changes of pancreas were correlated with the pressure and duration of autologous bile perfusion into pancreatic duct. It was easier to produce acute hemorrhagic necrotizing pancreatitis in the groups with a higher pressure and a longer duration of perfusion than in the groups with a lower pressure and a shorter duration. The results indicated that there was a significant effect of higher pressure and longer duration bile perfusion into pancreatic duct on the severity of induced acute pancreatitis.
Objective To investigate the diagnosis and treatment of pulmonary arterial hypertension ( PAH) due to rare causes. Methods The clinical presentation, laboratory testing, diagnosis and treatment of 4 patients with PAH associated with rare causes in Beijing Anzhen Hospital from January 2001 to March 2008 were analysed retrospectively. Results Primary biliary cirrhosis, hyperthyroidism, antiphospholipid syndrome and pulmonary artery sarcoma may cause PAH, which were improved after corresponding diagnosis and management. Conclusion PAH can result from rare causes. The enhancement of its recognition will help earlier diagnosis and treatment and improve the prognosis.

Methods Serum from 10 patients with ICP (ICP group) and from the healthy placental tissue of 10 normal people (control group) were collected from March to July, 2005. Cell culture and radioimmunoassay methods were used to investigate the corticotropin-releasing hormone (CRH) levels in placental tissue. Results The level of CRH in human placental tissue treated with sera of ICP was lower than that in the control group. 24, 48, 72, and 96 hours after treated with the serum, the levels of CRH in the ICP group were (84.95±34.98), (74.57±29.93), (71.16±27.26), and (81.07±37.18) pg/mL, respetively;while in the control group were (103.74±30.85), (108.27±23.77), (109.20±23.81), and (118.15±26.84) pg/mL, respectively. There was significant difference in the levels of CRH between ICP group and control group 48 hours after the culture (Plt;0.05). Conclusion The serum from the patients with ICP may inhibit the excretion of CRH in the placental tissue.
【Abstract】ObjectiveTo explore risk factors of bile leakage after primary ductal closure following choledochotomy. MethodsA retrospective clinical analysis was made in 148 cases of Ttube drainage and 154 cases of primary common bile duct suture following choledochotomy admitted to our hospital from January 1999 to June 2003. Results Postoperative bile leakage was seen in 11 patients of the group with Ttube drainage and in 16 patients of the group with primary suture respectively, there was no significant difference(Pgt;0.05).In the group with primary common bile duct suture,the occurrence of bile leakage was relative with hyperglycemia(Plt;0.05)，hypoproteinemia (Plt;0.01)，bile duct repeated sutures(Plt;0.01)and positive bacterial culture in bile(Plt;0.05). Bile leakage was not relative with elder age (Pgt;0.05).Conclusion It is the key factors,including chosing appropriate patients, intraoperative special examination, careful manipulation and effective medical treatment that can reduce the morbidity of bile leakage.
ObjectiveTo observe the effects of oral Xiaoyan Lidan tablets(XYLDT) on the bile composition(total bile acids, cholesterol, phospholipids) in patients with intrahepatic duct stones after common bile duct exploration(CBDE) with T tube drainage, to explore its possible preventive effects on stone recurrence. MethodsForty consecutive patients with intrahepatic bile duct stones who underwent CBDE with T tube drainage were randomly divided into experi mental group and control group. XYLDT were administrated at day 4 after surgery in experimental group(n=20), while none of medication were given in control group(n=20). 2 mL of bile was collected through T tube in both groups at day 1, 2, 3, 7, 14, and 21 postoperatively. Total bile acids(TBA), cholesterol(CHO), and phospholipids(PLIP) in bile were measured, and TBA/CHO ratio and PLIP/CHO ratio were calculated respectively. The results were statistical analyzed. ResultsThe demographic data in both groups including age, gender, height, weight, preoperative concomitant diseases, operative time, postoperative complications, hospital stays, serum total bilirubin, direct bilirubin, alanine aminotransferase(ALT), aspartate aminotransferase(AST), and amylase were not significantly different(P > 0.05). The measurements of TBA, CHO, PLIP, and the ratio of TBA/CHO and PLIP/CHO in bile were not significant on day 1, 2, and 3 after surgery in both groups(P > 0.05). In experimental group, the TBA, CHO, and PLIP on day 7, 14, and 21 after surgery were significantly increased compared with the control group(P < 0.05). The ratio of TBA/CHO on day 7, 14, and 21 was 2.17±0.29, 2.29±0.44, and 2.59±0.58, the ratio of PLIP/CHO was 2.03±0.68, 2.84±0.64, and 2.86±0.77, respectively, which were also significantly increased compared with the control group(P < 0.05). ConclusionsOral XYLDT can increase the secretion of TBA, CHO, and PLIP, elevate the TBA/CHO and PLIP/CHO ratio, and change the bile composition which may increase the dissolution of cholesterol in the bile. Presumably, oral XYLDT may have preventive effects in the recurrence of intrahepatic bile duct stones.
Objective To study glutamine (GLN) and cholecystokinin (CCK) effects on prevention of cholestasis in total parenteral nutrition (TPN). Methods White rabbits were choosed as TPN models, which were divided into four groups, group 1, TPN only (n＝10); Group 2, TPN plus GLN administration (n＝10); Group 3, TPN plus CCK (n＝10); Group 4, TPN plus GLN and CCK administration. Bile components were assayed and the structural change in gallbladder and liver were observed under light and election microspes at the forth and eighth week. Results Increasing of bilirubin and cholesterol was observed in the 1st and 2nd groups at the forth week, but increasing in the 3rd group was observed at the eighth week. The 4th group was normal. Changes of gallbladder and liver structure in 1st and 3rd group occured at the forth week. Changes of 2nd group occured at the eighth week. No structural change was found in the 4th group. Conclusion The test prove that cholestasis would occure during TPN and become serious with time prolonging. Integrity and function of gallbladder-wall tissue cell could be defended and sustained by applying GLN, but there is no direct preventing action. There is apparent cholecy stokinetic and cholagogic fundations by applying CCK. But CCK would lose its function if gallbladderwall was damaged. The test prove that TPN+GLN+CCK is the best way to prevent cholestasis during TPN.
Objective To explore the effects of bile from anomalous parcreaticobiliary ductal union (APBDU) patients on the growth of hunan cells of bile ducts, and the relationship between APBDU with bile duct carcinoma. Methods Bile sample from APBDU patients and normal persons were used for cells of bile ducts. The proliferative effect of bile was measured by mathabenzthiazuron (MTT) assay; Cell cycle and apoptosis were analyzed by flow cytometry (FCM); Expression level of c-erbB-2 was detected by Western blot assay. Results Bile from APBDU patients significantly promoted the proliferation of human cells of bile ducts compared with normal bile （P＜0.05）. The effect was abolished by addition of COX-2 inhibitor or iNOS inhibitor. The percentage of S period cells in group pretreated with APBDU bile was significantly increased compared with pretreated with normal bile (P＜0.001). The expression level of c-erbB-2 was increased in cell pretreated with APBDU bile. Conclusion Bile from APBDU patients can promote the proliferation of normal cells of bile ducts and may have potential carcinogenesis.
