In the presence of antischistosomular serum(Ab), the adherence of macrophages(M?). eosinophils(Eos) and neutrophils(Neu) to and the killing effect on schistosomula of Schistosoma japonicum were studied with a mouse model. In vitro experiment showed that all the three kinds of effectcr cells could adhere to the surface of the schistosomula when opsonized with specific Ab resulting in the significant increase in the percentage of dead schistosomula. When SPA was added to the system, the percentage of schistosomula with adherent cells decreased markedly. It was revealed that the adherence of cells was at least partially through the binding of Fc fragment of IgG to Fc receptor on the cell surfaces. After having been incubated with Ab and/or cells for 18 h in vitro, the schistosomula were inoculated into the peritoneal cavity of mice. The adult recovery rate 6 weeks after inoculation in groups Eos+Ab and M? + Ab were significantly lower than that of the control group (P

Objective To investigate clinical features and management of complicated or rare vulvovaginal anomalies derived from urogenital sinus malformation.Methods Medical documents of 6 cases with vulvovaginal anomalies treated in Department of Obstetrics and Gynecology in Peking Union Medical College Hospital in the past 10 years were reviewed retrospectively.According to embryological and anatomical characteristics,the classification system were established.Results This kind of vulvovngihal anomalies was very rare and not enrolled into current diagnosis and treatment system. All patients had a common clinical features:menstruation bleeding and urine from the same outflow tract;and two orifices on perineum were found by bimannal examination,one orifice located under clitoris,the other orifice Was anus.No vagihal vestibule and vulvar were observed between those two orifices.According to clinical features,those 6 cases were divided into 3 types:type Ⅰ Was persistence of distant urogenital sinus with clinical manifestation of simple labial fusion;type Ⅱ was low communication between vagina and urogenital sinus (infrasphincterie),presenting with distal vaginai atresia and urethrovagihal fistula;type Ⅲ was high communication (suprasphincteric) with distal vagihal atresia and more proximal urethrovavihal fistula.Type Ⅲ was frequently associated with severe rectum and anus anomaly,and other malformation as well.All patients were treated by surgical correction.Basically.the principle of operation wag to reconstruct perineal appearance,release the obstruction,and rear the defect and ultimately recovering the normal function.The alternative surgical methods should be considered individually.Conclusions The vulvovnginal anomalies derived from urogenital sinus malformation were complicated clinically.To establish classification system will be benefit for clinicians to make diagnosis and choose appropriate treatment. The individualized surgery should be performed on those patients to restore the structure and function,in the mean time,the factors associated with esthetics.sex and psychics should be considered.

Objective To investigate the route of minimal invasive sling procedures and evaluate their safety. Methods Tension-free vaginal tape (TVT),TVT-obturator (TVT-O) and posterior intravaginal sling (P-IVS) procedure were performed on five fresh pelvis.4% formaldehyde was used to preserve the cadavers and colored latex was injected into the vessels.An anatomic study and measurements between the trocars and related vessels or organs were carried out.Results There was no complication during all injections.The distance between TVT trocar and pubic vessels,the bladder,external lilac vessels and obturator vessels were 0.6,0.6,4.2 and 4.3 cm,respectively.Out of control of TVT trocar,the axial rotation or lateral diversion of TVT handle could injure these structures.We found during TVT-O operation,the retropubic space was not violated.The right placement of introducer was very important. When the beginning point was too deep into the anterior vaginal wall,2.2 cm proximal to urethral meatus or on a horizontal plane with a 35° angle relative to the urethral sagittal plane,the introducer would enter the retropubic space or perforate the upper posterior zone of the obturator membrane,where the obturator vessels and nerves exit the obturator canal.Based on our study,the diversion of P-IVS trocar would damage the rectum,and the pudendal vessels and nerves were relatively safe.Conclusions The TVT trocar passes the retropubic space and may injure the important vessels or organs.The route of TVT-O inside-out operation is stable and the retropubic space is not violated.The blunt design in the P-IVS trocar tips is helpful to reduce injury.

The effects of various soluble extracts of Ascaris suum on human blood coagulation were studied. The extract of whole worm could prolong recalcification time (RT) and kaolin-activated, partial thromboplastin time (KPTT), but did not alter prothrombin time (PT), indicating that the intrinsic pathway of blood coagulation was inhibited by this extract, but the extrinsic pathway was not affected. Whole worm extract inhibited platelet aggregation induced by ADP, but did not influence the one induced by adrenaline. Neither whole worm extract nor body fluid caused fibrinolysis. In KPTT assays with three dif-ferent extracts, cuticle extract exhibited the strongest anticoagulant activity, while whole worm extract and body fluid much less so. These data suggested that anticoagulants of ascaris mainly exist in the cuticle,

Objective To reclassify the patients with former diagnosis of vulvar intraepithelial neoplasia (VIN)Ⅱ, VIN Ⅱ - Ⅲ, VIN Ⅲ, Bowen disease and Bowenoid papulosis according to the 2004 modified terminology of International Society for the Study of Vulvar Disease (ISSVD) and evaluate the effects of surgical treatment. Methods According to the 2004 modified terminology of ISSVD, a retrospective review of the histological slides of 19 cases, who diagnosed as VIN Ⅱ , VIN Ⅱ - Ⅲ, VIN Ⅲ,Bowen disease and Bowenoid papulosis treated in Peking Union Medical College Hospital from 1999 to 2006,were performed to reclassify by pathologist and the clinicopathologic data were also analyze& Results According to the 2004 modified terminology of ISSVD, all 19 cases were reclassified as usual type VIN and were belonged to the subtype of warty type except one, the only Bowen disease patient whose one of focuses belonged to the subtype of basaloid type and the other focus belonged to the subtype of warty type. The primary cure rate of extended local excision was 89% (17/19). There were two cases recurred during follow-up period, and were cured by second surgical treatment and the focuses of recurrence site were still diagnosed as warty type VIN. Conclusions The patients with former diagnosis of VIN Ⅱ , VIN Ⅱ-Ⅲ, VINⅢ, Bowen disease and Bowenoid papulosis are basically reclassified as usual type VIN (warty type) according to the 2004 modified terminology of ISSVD. The results showed that the diagnosis of VIN could be simplified by new terminology. The surgical excision is the good choice and combined cytologic and human papillomavims (HPV) test during follow up is also important for patients of VIN.

This study was to investigate the diagnosis value of simplified uredynsmic test in stress urinary incontinence. Fifty patients with stress test-confirmed urine incontinence underwent simplified urodynamic test before routine urodynamic test. Detrusor instability, max bladder volume, average flow rate, and residual urine of simple urodynamic test were compared. Simplified urodynamic test showed a sensitivity of 87%, specificity of 9/12, positive predictive value of 92%, and negative predictive value of 9/14. There was no significant difference in max bladder volume, average flow rate, and residual urine between the two tests. Simplified urodynamic test might be a reliable method for diagnosis of stress urinary incontinence, and could be used for detrnsor instability screening.

Objective To study the clinical presentation and pathological features of rare nonepithelial vulvar tumors. Methods The clinical data of 42 patients with nonepithelial vulvar tumors who were operated on during 1986 to 2007 in Peking Union Medical College Hospital were analyzed. Results The average age of 42 patients was 44. 1 years. There were 32 eases (76%) with a vulvar mass. Twenty one of these 42 patients (50%) complained of associated symptoms of itch and pain Surgical treatment was the chief treatment of nonepithelial vulvar tumors, which included local excision (40, 95%), simple vulvectomy ( 1,2% ) and radical vulveetomy ( 1,2% ). Among the pathological diagnoses after operation,the most common benign histological subtypes were hidradenoma and haemangioma, while the must common malignant histological subtypes were leiomyosarcoma and aggressive angiomyxoma. Conclusions Most of the nonepithelial vulvar tumors are mesenehymal tumors. The clinical presentation has no special characteristics. Diagnosis of nonepithelial vulvar tumors can be made based on histological inspection.Surgical treatment is the treatment of choice.
