ObjectiveTo compare the clinical effects of laparoscopically assisted vaginal hysterectomy (LAVH) and transabdominal hysterectomy (TAH).MethodsOne hundred and twenty-six cases operated with hysterectomy were classified into LAVH group and TAH group by random digits table with 63 cases each.The operation time,intraoperative bleeding amount,exhaust time,hospitalization time and postoperative complications were observed and compared.ResultsThe operation time,intraoperative bleeding amount,exhaust time and hospitalization time was ( 115.6 ± 13.8 ) min,(92.5 ± 11.3 ) ml,(21.8 ±4.8) d and (6.1 ± 1.7) d in LAVH group,( 82.5 ± 8.7) min,( 112.3 ± 17.8) ml,(28.9 ± 6.2) d and (9.6 ±2.2) d in TAH group,there were significant differences between two groups (P<0.05).The incidence of incision pain,delayed wound healing,vaginal stump infection,thrombophlebitis,and gastrointestinal disorders was 9.5%(6/63),0,1.6%(1/63),0 and 7.9%(5/63) in LAVH group,which was significantly lower than that in TAH group [52.4%(33/63),7.9%(5/63),11.1%(7/63),7.9%(5/63) and 22.2% ( 14/63 ) ] (P < 0.05).ConclusionCompared with TAH,LAVH can shorten exhaust time,hospitalization time,reduce intraoperative bleeding amount,decrease complication rate,which can be further applied in clinic.

ObjectiveTo discuss the clinical value of serum CA125 and endometrial antibody (EMAb) for the diagnosis of endometriosis.Methods216 patients were determined by the presences of CA125 and EMAb before operation.ResultsAll cases were diagnosed by pathology after operation. CA125 positive rate in the endometriosis group was 58.3% and that in the control group was 12.5%. The difference between two groups was significant (P<0.01).EMAb positive rate in the endometriosis group was 31.3% and that in the control group was 14.3%. The difference between two groups was also significant (P<0.01). When determining CA125 alone to diagnose endometriosis, the sensitivity rate was 58.3% and specificity rate was 87.5%. If determining EMAb alone to diagnose endometriosis, the sensitivity rate was 31.3% and specificity rate was 85.7%. When one of them was used as diagnostic criterion, the sensitivity and specificity were 64.6% and 73.2% respectively. If combining use of both CA125 and EMAb as diagnostic criterion, the sensitivity and specificity were 25.0% and 100% respectively.Conclusions The determination of serum CA125 or EMAb levels is helpful for the qualitative diagnosis of endometriosis, especially using them combined, the diagnostic accuracy may be enhanced.

Objective To investigate the short term effect of gastric bypass surgery for the treatment of nonobese type 2 diabetes mellitus and possible mechanisms. Methods The clinical data of 58 patients with nonobese type 2 diabetes mellitus who received gastric bypass surgery from March to August, 2009 were retrospectively analyzed. The levels of fasting plasms glucose (FPG), 2-hour postprandial plasma glucose (2h PG) and glycosylated hemoglobin (HbA1c) were dynamically monitored, and the insulin resistance index (HOMA-IR) and body mass index ( BMI) were calculated. All data were analyzed using variance of analysis and LSD test. Results Of the 58 patients, 48 (83% ) met the requirement of complete response criteria and stopped administration of hypoglycemic agents; 7( 12% ) had to use hypoglycemic agents, but the dose of the agents was lowered by 50% compared to that before surgery. The surgery was ineffective in 3 patients (5% ). The levels of FPG, 2h PG, HbAlc and HOMA-IR of the 58 patients showed a significant decreasing trend after surgery when compared to those before surgery (F = 67. 867, 50. 885, 78. 278, 572. 757, P <0.05), while there was no significant change of the BMI after surgery ( F = 3. 503, P > 0. 05 ). Conclusions Gastric bypass surgery has a good effect on nonobese patients with type 2 diabetes mellitus whose BMI was less than 25 kg/m2. The improvement of insulin resistance after the surgery might be the main reason.

Objective:To evaluate the dental biofilm penetration efficiency of a novel stabilized stannous-containing sodium fluoride dentifric(EXP) and its lipopolysaccharide (LPS) neutralization efficiency.Methods:A controlled,randomized,examiner-blind in situ clinical trial was conducted with the treatment of PBS(control),EXP and a marketed stannous-containing sodium fluoride dentifrice (MKD).Fluorescent dye,fluorescent probe and fluorescence colocalization were used for sample examination and analysis.Results:EXP offered better stannous penetration into the biofilm than MKD and PBS(P <0.05),as well as greater LPS neutralization efficiency(P <0.05).There was a 96.52% overlap of stannous ions and bounded LPS at the same sites treated by EXP.Conclusion:EXP is more effective than MKD in the delivery of stannous into the biofilm and in the neutralization of LPS.
