ABSTRACT
The present study examined von Willebrand factor (vWF) levels and ADAMTS13 activity in pregnant and severe preeclamptic women in order to shed light on the prothrombotic state in severe preeclampsia. Thirty healthy women of childbearing age, 22 second trimester pregnant women, 30 third trimester pregnant women and 10 severe preeclamptic patients were recruited in this study. ADAMTS13 activity was determined by the FRETS-vWF73 assay and vWF antigen (vWF:Ag) levels by an enzyme-linked immunosorbent assay. The results showed that there were statistically significant differences in plasma vWF antigen levels between the severe preeclamptic and third trimester pregnant women, between third and second trimester pregnant women (P<0.05). The third trimester pregnant women had significantly lower plasma ADAMTS13 activity than second trimester pregnant women (P<0.05). Nevertheless, no significant differences in plasma ADAMTS13 activity were found between severe preeclamptic patients and the third trimester pregnant women (P>0.05). In conclusion, plasma ADAMTS13 activity is normal in severe preeclampsia despite the increased vWF:Ag levels. Prothrombotic state is involved in the pathogenesis of severe preeclampsia, as a result of endothelial injury.

ABSTRACT
Objective To explore clinical value of transvagiTIa ultrasound in diagnosis of cctopie oviductpregnancy.Methods EUB-2000 ultrasound diagnosis meter was used,the vagina probe head frequency is 5～10MHz,after the vagina to the womb,the double-side ovary,the double side oviduct and its periphery organizes to carry on omni-direetionally sweeps looks up.Results Transvagina ultrasound diagnosis ectopic pregnancy center oviduct pot abdomen pregnancy 158 cases,the oviduct canyon department 4 cases,between the oviduct the nature department pregnancy 2 cases,all pass through the cefioseope of our hospital.Coincidence rate was 100%.Conclusion Transvagina ultrasound diagnosis ectopie pregnancy is one of most accurate ultrasound diagnosis methods presendy,suggested various basic units hospital widely develops.
ABSTRACT
Objective To investigate effects and techniques of laparoscopic assisted transvaginal hysterectomy (LAVH). Methods Laparoscopic assisted transvaginal hysterectomy was carried out in 121 patients with hysteromyoma, cervical intraepithelial neoplasia grade Ⅲ, uterine adenomyoma, ovarian tumor, or atypical hyperplasia of endometrium, which were all indications for uterus resection. Results LAVH was performed successfully in 117 cases, whereas a conversion to open surgery was required in 4 cases because of serious adhesion, the success rate being 96 7% (117/121). The mean operating time was 95 min (range, 58~192 min). The mean amount of intraoperative blood loss was 120 ml (range, 100~250 ml). The postoperative hospital stay was 5~8 days. Conclusions LAVH was associated with mild trauma, slight intestinal disturbance, and quick recovery. Whether or not an operation is successful is related to the size, shape and mobility of the uterus, vaginal space, and operator’s skills and experience.
ABSTRACT
Objective To investigate the efficacy and safety of hysteroscopic treatment for submucous uterine myoma.Methods From January 2000 to December 2004,a total of 168 women with submucous leiomyoma of the uterus were treated by hysteroscopy in our hospital.According to the type of the myomas,electro-resection was performed in different ways.For the patients with massive hemorrhage or older than 45 years,the endometrium was resected during the operation.Results The operation was completed in all the cases within 5 to 65 minutes mean,(27.6?12.1)minutes].The mean blood loss was(40.1?10.2)ml(8-50 ml).After the surgery,2 patients developed uterine perforation,3 had hyponatremia,and 5 showed transient fever.Among the patients,160(95.2%)were satisfied with the outcomes of the surgery.Conclusions Transcervical electro-resection by hysteroscopy is a minimally invasive,safe,and effective method for submucous uterine myoma.Preoperative preparation,strict indication criteria,and intraoperative monitor are three key points to avoid operation-related complications.
