ABSTRACT
A new minimally invasive gallbladder-preserving operation has emerged for the treatment of gallbladder stones,but fundamentally it is a replica of the previous gallbladder preservation method.The gallbladder aids in digestion but is not essential for life.Its function should not be exaggerated and should not instigate trivial reasons for its preservation.Most patients undergoing cholecystectomy maintain a good quality of life.The causes,mechanisms,and prevention of gallstone formation remains mysterious,so a high recurrence rate after gallbladder-preserving operation is difficult to avoid.A full cholecystectomy can avoid recurrence complications and the benefits outweigh the risks.A discussion of the benefits and complications must be initiated to evaluate both treatment modalities for gallstones.
ABSTRACT
OBJECTIVE:To study the protective action of tea phlyphenol(TP)on HepG2cells injury and the possible mechanism.METHODS:Different concentrations of TP were added into HepG2cell culture fluid,which was then added with H 2 O 2 and CCl 4 to form2kinds of injury models,cell survival rate was figured out by detecting the optical density value and changes of AST activities were monitored.RESULTS:As compared with model group,different concentrations of TP increa_ sed the survival rate of the injured HepG2cells,and reduced the activities of AST(P
