Objective To evaluate the role of laparoscopic exploration in patients with chronic abdominal pain. Methods Sixty patients with chronic abdominal pain were selected for laparoscopic evaluation. Results of 60 patients, 35 cases were operated on by laparoscopic appendectomy and lysis of adhesion,20 cases by lysis of ad- hesion simply, and 5 cases by simple irrigation of the pelvis. Forty five patients were followed up from 0.5 to 5 years, complete pain relief rate was 53 % (24/45), partial pain relief rate was 29% (13/45), the other 18% (8/45)got no im- provement of their addominal pain. Conclusions Laparoscopic diagnosis and treatment in patients with chronic ab- dominal pain have the following advantages: extensive exploration, multidisciplinary diagnosis and treatment in combi- nation, as well as accuracy and effectiveness.

By applying the methods of inter—element meter andmean line,decoction solution of 110 recipes were anal-ysed for the characteristics of distribution of inorganicelements.In those recipes containing more warm-heat drugs,the contents of most elements were higherthan the line of average value,while those with morecool—cold drugs,lower than the mean line,suggest-ing that the distribution value of inorganic elementsmay be a determining factor responsible for the cold-heat quality of a recipe.
