Objective To evaluate the efficacy and safety of fluoroscopy guided frequency-doubled double-pulsed laser lithotripsy for removing difficult bile duct stones. Methods From March 2008 to December 2009, patients with difficult bile duct stones were divided into cholangioscopy guided group ( n = 21 )and fluoroscopy guided group ( n = 19) to receive corresponding treatments. The success rate of complete stone removal and the complication rate related to the procedure were compared between the two groups.Results There are no significant differences between 2 groups in regarding of either success rate of complete stone removal ( 19/21, 90. 5% in cholangioscopy guided group vs. 17/19, 89. 5% in fluoroscopy guided group, P >0. 05 ) or rate of procedure related complication (4/21, 19. 0% in cholangioscopy guided group vs. 3/19, 15. 8% in fluoroscopic guided group, P = 0. 559 ). Conclusion Frequency-doubled doublepulsed laser lithotripsy guided by cholangioscopy or fluoroscopy are both safe and effective.

Objectiye To evaluate the therapeutic efficacy and safety of (endoscopic sphincterotomy, EST) plus balloon dilation for difficult bile duct stones. Methods Patients with difficult common bile duct stones on endoscopic retrograde cholangiopancreatography (ERCP) from March 2008 to December 2009 were randomly divided into 2 groups to receive EST or EST plus balloon dilation ( EST + EPBD), respectively. The success rate of complete stone removal, number of endoscopic sessions, the rate of using mechanical lithotripsy and the complication rate related to the procedure were compared between the 2 groups. Results Compared with EST alone, EST plus balloon dilation resulted in similar outcomes in terms of overall successful stone removal rate (2/62 vs. 2/61 ) and early complication rate (4/62 vs. 6/61, P >0. 05). However,EST group needed more sessions ( EST 15/46 vs. EST + EPBD 5/57, P <0. 05) and use of mechanical lithotripsy to achieve complete removal of stones ( EST 12/61 vs. EST + EPBD 4/61, P <0. 05 ). Conclusion EST plus balloon dilation is as safe and effective as, but more convenient than EST, for endoscopic removal of common bile duct stones.

Objective To analyse the nutrients of Acaudina leucoprocta and explore its hypolipidemic effect. Method The nutrients constituents of Acaudina leucoprocta were analyzed by high-performance liquid chromatography,and was compared with Apstichopus japonicus. The hyperlipidemia model was estabolished by feeding SD male mice with high fat feed. The change of liver index and fat coefficient as well as the effects on serum lipid,antioxidant capacity of serum in rats were observed. Results The fat content of Acaudina leucoprocta was only 0.43%,significantly lower than that of Apstichopus japonicus. The content of amino acids in Acaudina leucoprocta was higher than that of Apstichopus japonicus. Acaudina leucoprocta would decrease the liver index,fat coefficient and TC,TG,LDL-C,LDL-C/HDL-C in serum significantly,and increase HDL-C and HDL-C/TC. MDA and NEFA contents were effectively reduced. GSH-Px activitives were enhanced. Conclusion Acaudina leucoprocta is very rich in protein,and low in fat content. It has hypolipidemic and antioxidative effects,and may reduce the oxidative damage caused by high fat diet. Acaudina leucoprocta may be used as a functional food.
