We reported two cases of pelvic retroperitoneal schwannomawe occurred in the young unmarried female successfully resected by laparoscopic surgery.One was a 16-year-old girl presented with secondary amenorrhea.Ultrasound and MRI found the existence of an ovarian cystic and solid mass,5.3 cm × 4.5 cm in size.Laparoscopic exploration found pelvic mass completely located in the left retroperitoneal obturator fossa and complicated with rudimentary horn of the uterus.The other was a 25-year-old female and asymptomatic.Ultrasound showed a mass in the right ovary.During operation a pelvic mass was discovered in the anterior of right sacral retroperitoneum,8 cm× 6 cm in size.Two cases of retroperitoneal lesions were preoperatively misdiagnosed as ovarian mass and had densely adhered to the surrounding tissues.Histopathologic examinations confirmed to be benign schwannoma and resected radically by laparoscopy without any complications.The operation time was 120 min and 166 min,respectively.The intraoperative bleeding was 150 ml and 600 ml,respectively.The S-100 protein on pathological immunohistochemistry showed strong positivity.We deem that laparoscopic resection is necessary for diagnosis and treatment of pelvic retroperitoneal schwannomawe,being safe and effective.Complete excision is benefical to prevent recurrence.

AIM:To discuss the application effect of adjustable sutures in glaucoma filtering operation after trabecular resection.
METHODS: Seventy-eight cases ( 101 eyes ) suffered from glaucoma were randomly divided into two groups, observation group and control group. Thirty-nine cases ( 51 eyes ) in the observation group underwent trabeculectomy with adjustable sutures, the control group (39 cases, 50 eyes) only adopted trabeculectomy.RESULTS: Compared Preoperative IOP in two groups, the difference was not statistically significant (P>0. 05). After 6mo, IOP were decreased compared with preoperative in two groups, and that in observation group was lower than control group, the difference was statistically significant ( P < 0. 05 ). Six months after operation, there were 1 eye with shallow anterior chamber Ⅰ and 2 eyes with non- functional bleb in observation group, and the complication rate was 5. 9%. While there were of 6 eyes with shallow anterior chamber, in which 4 eyes at gradeⅠ, each one at gradeII and Ⅲ. Non-functional blebs in 5 eyes and a scleral flap adhesion complications rate in the control group was 24. 0%, significantly higher than that in the observation group, the difference was statistically significant ( P<0.01).
CONCLUSION: The adjustable sutures combined with trabeculectomy for glaucoma can significantly reduce the postoperative complications. The curative effect is exact and clinically applicable.

BACKGROUND: Taohong Siwu Tang is made up of Taoren, Honghua,Danggui, Chishao and Chuangxiong. Paeoniflorin is one of the major effective components in Radix Paeoniae Rubra Extracts and Taohong Siwu Tang, and it can promote blood circulation and remove blood stasis and has the effect of anti-acute myocardial ischemia.OBJECTIVE: To compare the serum concentration of paeoniflorin in mice after intragastric administration (i.g.) of Radix Paeoniae Rubra extracts and Taohong Siwu Tang.DESIGE: Rndomized controlled observation.SETTING: Department of Pharmacy and Department of Basic Medicine,Hebei North University.MATERIALS: The trial was performed in the first laboratory of Department of Pharmacy, Hebei North University during February to June 2005.Eighty involved Kunming mice of either gender and of clean grade, with body mass of 18 to 22 g, were purchased from Experimental Animal Center, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences. Taoren, Honghua, Danggui, Chishao, Shengdi and Chuanxiong 6 Chinese herbs were all purchased from Zhangjiakou Institute of Traditional Chinese Medicine.METHODS: ①Blank serum was isolated from eight mice which were fasted for 12 hours. Control sample solution of paeoniflorin was added into blank serum. Acetonitrile was used to deposit protein, the solution was centrifugated and isolated ,and 20μL supernatant was taken to obtain regression equation. ② Seventy-two Kunming mice were randomized into Radix Paeoniae Rubra extracts group and Taohong Siwu Tang group, with 36 mice in each. After being fasted for 12 hours, the mice in each group were intragastric administration of Radix Paeoniae Rubra extracts and Taohong Siwu Tang, respectively and the concentration of paeoniflorin was 300 mg/kg.1 mL blood was taken respectively at 15, 30, 60, 90, 120 and 180 minutes after intragastric administration and prepared into serum sample (6 mice at each time point in each group). The time to peak and difference in peak concentration of serum paeoniflorin were compared between intragastric administration of Radix Paeoniae Rubra extracts and Taohong Siwu Tang.The concentration of paeoniflorin was measured with high-performance liquid chromatography (HPLC). Chromatographic condition: chromatographic column YWG-C18 (250×4.6 mm,10 μm). The mobile phase was methanolKH2PO4 (0.05 mol/L) (38∶62) at a flow rate of 1.0 mL/min. The detective wavelength was set at 230 nm. The column temperature was 25 ℃.MAIN OUTCOME MEASURES: Serum concentration of paeoniflorin after administration of Radix Paeoniae Rubra extracts and Taohong Siwu Tang in mice.RESULTS: Seventy-two mice were used for Radix Paeoniae Rubra extr acts and Taohong Siwu Tang tests, and all of them entered the stage of result analysis without deletion. ① Chromatographic isolation results: Paeoniflorin could be well isolated from other components. The linear range for detection of paeoniflorin was 5.40-646.0 μg/mL. The mean recovery rate was 93.6% and the limit of detection was determined as 1.08 mg/L. ②Comparison of concentration of serum paeoniflorin of mice between two groups: The concentration of serum paeoniflorin in the Radix Paeoniae Rubra extracts group and Taohong Siwu Tang group reached the peak at 30 and 60 minutes after intragastric administration, respectively. The peak concentration of paeoniflorin of Taohong Siwu Tang group was lower than that of Radix Paeoniae Rubraextracts group [(36.27±5.72) mg/L vs.(46.82±5.29) mg/L, P ＜ 0.01 )].CONCLUSION: The concentration of serum paeoniflorin is significantly decreased after intragastric administration. It was further confirmed the decreased concentration of the crude paeonifiorin in the mice sera might result from promotion of its metabolic conversion by other chemical components in the complex prescription. This result needs further investigation.
