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.
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 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.

ObjectiveTo explore the relationship between the levels of transferrin (TRF), prealbumin (PAB) and total bile acids (TBA) in serum and the loss of the hepatic reserve function in primary liver cancer (PHC) patients and the importance of the former factors for diagnosis of PHC. MethodsA total of 154 patients with PHC collected between March 2010 and February 2013 were included in our study. Based on the information of hepatic reserve function and the Child-Pugh classification standard, the patients were divided into Child-Pugh-A, B, and C groups with 67, 55 and 42 patients respectively. Another 58 healthy subjects were selected as the control group. Serum TRF, PAB and TBA levels were measured by automated chemiluminescence immunoassay, immune turbidimetric assay and enzymatic cycling respectively, and they were compared among the groups. ResultsTRF level of patients in the control group and Child-Pugh-A, B, and C groups was respectively (2.574±0.214), (1.618±0.135), (0.988±0.121), and (0.314±0.107) g/L, with significant differences among the groups (P<0.05). PAB level of patients in four groups was respectively (269.32±37.29), (165.22±21.01), (123.24±31.15), and (83.66±19.74) mg/L, with significant differences among the groups (P<0.05). TBA level in the above four groups was respectively (9.16±2.48), (65.13±4.25), (133.62±8.44), and (250.73±21.59) μmol/L, and there was also significant differences among the groups. A positive correlation between serum TRF and PAB was found (r=0.927, P<0.001), and negative correlations between serum TBA level and serum TRF and between TBA and PAB were found (r=-0.454, P<0.001; r=-0.432, P<0.001, respectively). ConclusionSerum TRF, PAB and TBA levels are closely related to the hepatic reserve function in PHC patients, and they can be used as an important indicator for PHC diagnosis.
To study of plasma lipoprotein cholesterol and effects of these changes on bile acids and cholesterol in bile during gallstone formation in rabbit model. This gallstone model was induced by high cholesterol diet (HCD). The rabbits were divided into five groups and there were ten animals in each group. The plasma highdensity lipoprotein cholesterol (HDL-C) and its subgroups (HDL2-C, HDL3-C), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), total cholesterol, triglyceride, phospholipid, bile acids and cholesterol of bile were investigated in different time. The results were as follow: ①As the time of feeding HCD passed by, the plasma total cholesterol, LDL-C and VLDL-C increased markedly (3-week group and 4-week group vs control group, Ｐ＜0.05). Though the plasma HDL-C and its subfractions HDL2-C and HDL3-C did not change significantly, the function of HDL in transporting plasma cholesterol decreased markedly (from 80.00% to merely 3.68%); ②Cholesterol in bile increased gradually and there were significant differences when 3-week group and 4-week group comparing with control group. The concentration of GDCA and GCA in bile changed slightly (Ｐ＞0.05). These results suggest that the changes of plasma lipoprotein cholesterol may affect the metabolism of cholesterol and bile acids and it may take an important role in the formation of gallstone.
The quantitative studies of secretory granules andand lysosomes in gallbladder epithelium and gallbladder bile glycoprotein were performed in 20 gallstone patients and 15 gallstone-free subjects. The results showed that the number, the volume density and the total secrectory granules were significantly increased in gallstone patients compared with gallstone-free controls. The gallstone patients had a markedly reduced number,volume destiny and total lysosome area compared with gallstone-free subjects. The glycoprotein concenrtation in gallblader bile was increased up to 21.04±4.92g/L in gallstone paients,as compare with 13.02±5.72g/L(Plt;0.05)in the stone-free controls. The qualitity of secretory granules and lysosomes was directly proprtational to that of bile glycproteins. Evidence and secrectory granules and lysosomes was directly proporional to taht of bile glycoproteins. Evidence and argument are presentded suggesting that gallblader epithelium secrectory granules affect the concentration of bile glycoprotein and lysosomemay be related to the intracellular degradation of secretory granules.
