Objective To investigate the treatment options of acute biliary pancreatitis.Methods A retrospective review was performed in 134 consecutive patients who presented to a single tertiary care institution from 2000 to 2010 with acute biliary pancreatitis.Results Of the 134 patients,30 had a persistent (commonbile duct,CBD)stone.Following multivariate analysis,at admission CBD size on ultrasound,alkaline phosphatase(ALP),total bilirubin(TB),significantly correlated with persistent CBD stone.Receiver operator curve analysis and linear regression were applied to obtain optimal and equitable predictive values,and variables combined.Optimal values were.,CBD≥10 mm;AP≥150 U/L;and TB≥51.3μmol/L.Presence of three variables had an associated odds ratio(OR)of29.5(P<0.001)for presence of persistent CBD stone.Zero variables conferred asignificantly decreased probability of CBD stone,OR 0.07(P<0.001).Conclusions Presence of three variables significantly correlated with persistent CBD stone.Biliary evaluation by endoscopic retrograde cholangiopancreatography(ERCP)is suggested.In the absence of any positive predictive variables,cholecystectomy may be sufficient.Decisions regarding patients with one to two be made vailables should occur on a case-to-case basis.

Therapeutic efficacy of transcather arterial chemoembolization for hepatic carcinoma and its influence on hepatic function: a retrospective study of 92 patients / 国际外科学杂志

Objective To evaluate the therapeutic efficacy of transcather arterial chemoembolization for hepatic carcinoma and its influence on hepatic function. Methods Patients with HCC were divided into three groups according to repeated TACE times. The therapeutic efficacy was assessed with survival rate, car-cionma size and biologic response (AFP). Hepatic function was evaluated according to some hepatic param-eters(ALT,AST,ALB,DB,TB,PT). Results All three groups responses rates were 4.3%, 23.1% and 31.6% ;srespectively,liver function in group 1 and group 2 returned to its pretreatment level(P <0.05) ,but in group 3, liver function did not return to its pretreatment level associated with more repeated TACE times. The 1-,2-and 3-year survival rates of group 1 were 27.0%, 10.8%, 5.4% ; respectively, while those of group 2 were 57.1%, 33.3%, 19.0% ; respectively, which were not significantly different from those of Team 3 ,which was 62.5%, 37.5%, 18.8%, respectively. Conclusions (1) three to four repeated times TACE was an effective palliative treatment that prolongs survival of patients with HCC,while 1 to 2 re-peated times had a limited benefit; (2) Irreversible hepatic impairment induced by TAEC could affect its therapeutic efficacy.

Isolation and purification of pig islet cells / 国际外科学杂志

Objective To establish effective method for large-scale purification of islet cells from pig pan-cress. Methods Pig pancreas tissue was digested with collagenase P followed by purification in a HCA-Fi-coil dis continuous gradient using Cobe2991 cell separator. After isolation, the islet cell yield and purity were evaluated with light microscope with DTZ staining, and the islet function assessed by insulin release as-say in vitro. Results The number of the islets coll ected from each pancreas averaged (275 000±20 895)islet equivalents (IEQ) before purification, and (230 350±26 679) IEQ after the purification with discon-tinuous gradient centrifugation. From each gram of the pancreatic tissue, (2710±229) IEQ were obtained with an average purity of (50.2±1.95) %. The purified islets responded well to high-concentration (16.7 mmol/L) glucose stimulation with a 4. 74-fold increase of insulin secretion over the basal level (3.3 mmol/L, P <0.001). Conclusion The established method can be applicable for large-scale purifi-cation of fully functional islet cells from pig pancreas.

Development of islet transplantation / 国际外科学杂志

Clinical islet transplantation is currently being explored as a treatment for its superiorities of lesser in vasive,lower risk,avoiding or preventing chronic complications.Because of the difficulty in isolation,purification and transplantation,the yield of islet is lower than needed;shortage of donor,difficulty in obtaining adequate islet cells for sustaining B cell mass and function over time,and immune rejection reactions are the hurdels to widespread application of islet transplantation.
