Objective To evaluate the clinical effect of laparoscopic common bile duct exploration combined with endobiliary drainage in the treatment of acute biliary pancreatitis.Methods A retrospective analysis was performed on the clinical data of 90 patients with acute biliary pancreatitis admitted to our hospital from January 2012 to May 2014.Among them,42 patients received laparoscopic common bile duct ex-ploration combined with endobiliary drainage (laparoscopic group),and 48 patients underwent endoscopic retrograde cholangiopancreatogra-phy (ERCP)combined with endoscopic sphincterotomy (ERCP group).The operation situation,changes in white blood cell (WBC) count,total bilirubin (TBil),alanine aminotransferase (ALT),and C -reactive protein (CRP)after operation,and follow -up results were analyzed.Comparison of continuous data between the two groups was made by t test,while comparison of categorical data was made by chi -square test.Results There were no significant differences in operation time,intraoperative blood loss,hospitalization expenses,and the incidence of complications between the two groups (all P >0.05).On the 1st,3rd,and 7th days after operation,the two groups had re-duced WBC count and serum levels of TBil,ALT,and CRP,but the reduction was significant only on the 3rd and 7th days in both groups (all P 0.05).In the 6 -month follow -up,the incidence of regurgitation cholangitis in the ERCP group was 6.25% (3 /48),but no complications were found in the laparoscopic group (χ2 =2.716,P =0.099).Conclusion Laparoscopic common bile duct exploration combined with endobiliary drainage is safe and feasible for acute biliary pancreatitis,and it can retain the function of the Oddi′s sphincter.

<p><b>OBJECTIVE</b>To reveal the effects of UV-B radiation on the growth of medical plant Mentha piperita, simulate an enhanced UV-B radiation and evaluate intensity of radiation on the photosynthesis of M. piperita.</p><p><b>METHOD</b>Three different levels of UV-B radiation were set in the experiment which included: natural light control (0 W x m(-2)), light UV-B radiation stress (0.15 W x m(-2)) and heavy UV-B radiation stress (0.35 W x m(-2)). The chloroplast ultrastructure, photosynthesis indexes and chlorophyll fluorescence parameters of the M. piperita were observed under the three treatments.</p><p><b>RESULT</b>Although the chloroplast ultrastructure was destroyed to some degree under the light UV-B radiation stress, F(v)/(F)m, F(v)/F(o), qP, phiPS II and ETR could resume to the comparative level of natural light control. At the same time, qN increased firstly and decreased thereafter. But under the high strength UV-B radiation stress, the photosynthetic structures were badly destroyed, which could not recover through protecting mechanism by itself.</p><p><b>CONCLUSION</b>It was showed that M. piperita was able to protect photosynthetic structures by increasing respiration and dissipation when photosynthetic capacity reduced under light UV-B radiation stress. It is demonstrated that M. piperita has high adaptation to light UV-B radiation stress, which is kind of promising medical plant for area with higher UV-B radiation.</p>
