Objective To explore the feasibility of laparoscopic operations in the treatment of ovarian benign tumors. Methods A retrospective analysis of 150 cases of ovarian benign tumors treated by laparoscopic surgery (146 cases of oophorocystectomy and 4 cases of adnexectomy) from January 1997 to October 2003 was made. Results Surgery was completed successfully in all the 150 cases and no conversions to open surgery were required. Mild extraperitoneal emphysema was observed in 2 cases and no other complications occurred. The mean blood loss was 100 ml, the mean operation time was 80 min, and the mean length of hospitalization was 4 3 days. A total of 128 cases were followed up for a mean of 3 8 years. Recurrence was found in 4 cases in 38 cases of endometriosis cysts. Among 15 patients complicated with infertility, conception occurred in 6 patients after surgery, with a pregnancy rate of 40%. Conclusions Laparoscopic surgery is safe and effective for ovarian benign tumors provided patients are properly selected.

Objective To discuss the clinical characteristics and treatment of amenorrhea caused by Tripterygium Wilfordii polyglycoside (TWP).Methods The sexual hormone levels of 25 outpatients of The First Affliated Hospital Of Wenzhou Medical College who suffered from secondary amenorrhea after the use of TWP were examined before and after the hormone therapy.In addition,the clinical presentations were observed.Results (1)The E2 level went down lower than 73.2pmol/L while FSH went up higher than 40U/L in all the 25 patients.Among them,24 patients were confirmed of the diagnosis of premature ovarian failure.⑵HT is an effective way for 20 patients.The total efficiency of the therapy was 80%.⑶The E2 secreted by ovary was higher (63.19?10.81)pmol/l vs. (365.45?161.60) pmol/L and FSH(110.72?21.52)U/L vs. 11.46?17.70)U/Lsecreted by pituitary was lower after therapy than before.⑷After the second period of therapy, the clinical perimenopausal symptoms of all the patients were improved to different degrees.Conclusion TWP may result in the disorders of ovarian functions, but and HT in time may be an effective therapy.

Objective To detect steroidogenic acute regulatory protein (StAR) expression in apolipoprotein E-deficient mice at different ages and serum lipid levels. Methods Nighty-six C57BL/6J and apoE-/- mice were enrolled, which were divided into 16 groups with 6 mice per group according to age (1 day, 1, 3, 5 months), sex and genotype (C57BL/6J and apoE-/-). The serum lipid levels in C57BL/6J and apoE-/- mice were detected by commercial kits. StAR mRNA and protein expressions in liver were detected by Real-time PCR and Western blot respectively. Results ApoE-/- mice had higher LDL-cholesterol and lower HDL-cholesterol compared with C57BL/6J mice of the same age and sex. StAR mRNA and protein expressions were decreased following with aging in C57BL/6J mice. However, in apoE-/- mice with higher lipid levels, StAR mRNA and protein expressions were changed with the lipid levels other than ages. StAR mRNA and protein increased in the early stage, and then decreased with the increasement of lipids levels. Conclusions StAR could affect lipids levels and may be an effective regulator for atherosclerosis and other cardiovascular diseases.

To explore the protective effects of trimetazidine on vascular endothelial cells injury induced by hydrogen peroxide (H2O2) and its pharmacological mechanisms of anti-oxidation.Methods Human umbilical vein endothelial cells (HUVECs) were injured by H2O2.Next,the cells were treated with three different concentrations of trimetazidine (1 μmol/L,10 μmol/L,100μmol/L,respectively).The viability of cells was detected by methyl thiazoeyl tetrazolium (MTT) assay.In addition,malondialdehyde (MDA)contents,superoxide dismutase (SOD) and secretion of NO were measured.Results Trimetazidine could enhance the viability of the injured HUVECs induced by oxidation,decrease the level of MDA,enhance the SOD activity,and increase the secretion of nitrogen monoxide.These effects were in a certain dose-dependent manner and the difference was significant among the three concentrations (P<0.05).Conclusions Our results suggest that trimctazidine may protect lipid peroxidation and prevent oxidation-induced cellular dysfunction of HUVECs (J Geriatr Cardiol 2008;5:248-251)

To analyze and evaluate the knowledge of Chinese Guidelines of Diabetes Prevention and Treatment in Shanghai medical staff. 175 medical staff working in endocrinology or community health were enrolled and evaluated by a questionnaire of guidelines about the state of professional, training, and related knowledge. Only 16. 6% medical staffwere trained about the guidelines( 46. 67% from the general hospitals, 14. 75% from secod-level hospital and 7. 14% persons from the community hospitals, P<0. 01 ). The total correct answer rate of the guidelines was 37. 36%. The correct rate of community hospitals was lower than others( P<0. 05 ). The rate of doctors' was higher than nurses'( P<0. 05 ). There were difference between doctors and nurses with the key point of diabetes care knowledge in different level hospitals. The effective method of clinical training in diabetes care should be explored. We still have to work hard to promote the effect of diabetes control and prevention. Effective training about the guidelines should be enhanced. The cooperation between general hospitals and community health institutions in diabetes prevention and treatment should be enhanced.
