Objective To study the incidence of complications of visceral and vascular injury in laparoscopic surgery for gynecologic diseases,and to discuss the ways to decrease the incidence. Methods The data of 2684 patients who received laparoscopic surgery from Januray 2003 to December 2005 in the Department of Obstetrics and Gynecology were reviewed retrospectively.The incidence and treatment of complications of visceral and vascular injury were observed. Results The total incidence rate of complications was 2.53%(n=68),and that of the visceral and vascular injury was 0.37%(n=10).Four cases of injury were related with trocar punctures(injury of omental blood vessel,n=2;postperitoneal vessel,n=2),three took place during the operation (severe bleeding,n=1;bladder injury,n=2),and the other three were observed in the postoperative stage(ureter injury,n=2;intestinal fistula,n=1). Conclusion The complications in laparoscopic surgery for gynecologic diseases are increased with the extension and difficulty of operation,and are closely related with the experience of the surgeons.Proper candidates for the surgery and established operative technique are the key factors in decreasing the incidence.

Objective: To study the absorption and transportation of euphobiasteroid in Caco-2 cell monolayer model. Methods: Caco-2 cell monolayer model was used to study the process of bi-direction transport of euphobiasteroid, and the effects of time, drug concentration, and inhibitors on the process were investigated. The concentration of euphobiasteroid was detected by UPLC-MS/MS, and the apparent permeability coefficient (Papp) and apparent permeability (PDR) were calculated. Results: During the transport process of euphobiasteroid in Caco-2 cells, the Papp values of variety concentration were from 1 × 10-6 to 1 × 10-5. The cumulative transshipment volume was increased with time and concentration, which presented concentration-dependent manner. The PDR values of 10, 30, and 50 μmol/L euphobiasteroid were 1.35, 0.83, and 0.65, respectively. Verapamil hydrochloride could promote the transportation of euphobiasteroid from AP side to BL side. Conclusion: The absorption of euphobiasteroid in intestine is moderate and mainly through passive transport. There may be excretion mechanism of intestinal transport protein in the intestine absorption of euphobiasteroid.

Objective To study on the relationship between psychological harmony and mental health of health care providers. Methods Surveys on psychological harmony and mental health were conducted in 313 health care providers in Heibei Province by psychological harmony and SCL-90 questionnaire. Results The general psychological harmony,and mental health level of health care providers is lower than the national level; The psychological harmony and its dimensionality of health care providers is affected mainly by many factors such as emotional stability, the level of patients' cooperation, on-duty situation in holiday time, salary, the rate of solving difficult miscellaneous diseases, the number of medical tangle and paranoid symptoms.etc., among which solving difficult miscellaneous diseases effectively is the most important factor. Conclusion The general psychological harmony situation does not affect health care providers' mental health.

Objective To observe protective and repairing effect of Aorui Gel on esophageal mucosa injury in reflux esophagitis rats. Methods Rat models of reflux esophagitis were established by partial pylori ligation plus cardiomyotomy. Model control group,low-,middle-and high-dose Aorui Gel groups,positive control group,excipient control group and sham operation group were set up. Rats were treated with the corresponding drugs 7 days after operation. After treatment for 14 days,the rats'general state,and macroscopic features and pathological features of esophageal mucosa were compared. Results Macroscopic features and pathological features of esophageal mucosa in Aorui Gel groups differed from those in the model control group,inflammation of esophageal mucosa in Aorui Gel groups was alleviated,and pathological features were relieved and arrived to the normal state. Conclusion Aorui Gel can alleviate esophageal mucosa injury in reflux esophagitis rats,indicating that Aorui Gel has protective and repairing effect on esophageal mucosa injury.
