Objective To evaluate suprapubic transvesical prostatectomy without partition of the prostatic cavity. Methods From Nov.1999 to Mar.2000,20 cases of BPH were treated by suprapubic transvesical prostatectomy without partition of the prostatic cavity and the therapeutic result was evaluated. Results The blood loss has been less.The patients have been followed up for 1～5 months.Neither incontinence nor bladder outlet obstruction has been noted.IPSS decreased from 29.4?2.0 to 8.8?2.0,Qmax increased from 6.8?1.3 ml/s to 16.8?2.0 ml/s,AFR increased from 3.5?0.9 ml/s to 10.0? 2.0 ml/s and QOL decreased from 5.5?0.5 to 1.7?0.5.All these differences were statistically significant ( P

Objective To study the different biomechanics surgical effects of posterolateral fusion , the transverse fusion and the interbody fusion. Method Scan CT was followed with preprocess of images. The Mimics , HyperMesh and Geomagic Studio Reverse engineering softwares were used to establish the modles of lumbar fusion , then the finite element computation was conducted by using the Abaqus finite element software. Result The EF of each lumbar modle was established , the EF of the interbody fusionwas rised evidently. After the fusion , the stress of the adjacent lumbar were also rised, among them the stress of the upper adjacent segment in tnterbody fusion was the most in extension and rotation , with statistical significance ( P < 0 . 05 ) . In the antexion the stress of the transverse fusion was the most, and the new type of posterolateral fusion least, three of them all hadstatistical significance (P<0.05). In the lateral flexion, they had no statistical significance (P>0.05). About the under adjacent sengment, in the extension and antexion, the stress of the interbody fusion was the most, and the new type of posterolateral fusion was the least, the three of them all haved statistical significance (P<0.05, respectively). In the rotation and lateral flexion, with no statistical significance (P>0.05). Conclusion After the fusion, the EF of the lumbar and the stress of the lumbar disc are all established, the interbody fusion is most, while the others are lower.

OBJECTIVETo explore various factors affecting the clinical pregnancy outcomes of artificial insemination with donor sperm (AID).

METHODSWe retrospectively analyzed 15,744 cycles of AID in 6302 women and investigated the association of the clinical pregnancy outcomes of AID with the treatment protocols, the times of insemination per cycle, the age of the infertile women, the status of the oviduct, and the number of AID cycles.

RESULTSThe pregnancy rate of AID was higher in the chlomiphene-treated women than in those of the natural cycle group (P = 0.003) but showed no significant differences either between the chloramiphene and human menopause gonadotropin (HMG) or between the HMG and natural cycle groups (P > 0.05), and so was it in the women that had received AID twice per cycle before and after ovulation (26.3%) than in those that had undergone only once before (7.0%) or after ovulation (23.7%) (P < 0.05). However, the pregnancy rate was remarkably lower in the women aged 35-40 years (16.5%), especially in those over 40 years (1.2%), than in those under 35 years (26.0%) (P < 0.05). There was no significant difference in the success rate of AID between the women with oviductal adhesion and those without (27.4% vs. 28.1%, P > 0.05). The pregnancy rate of the first cycle of AID (27.6%) was markedly higher than those of the second (24.7%), third (23.9%), and fourth (23.1%) (P < 0.01), but with no significant differences among the latter three cycles (P > 0.05), while that of the fifth cycle (19.0%) was remarkably lower than those of the first four (P < 0.01).

CONCLUSIONThe age of the infertile women is an important factor affecting the success rate of AID. AID twice per cycle is better than once only. For those without oviductal factors, at least 4 cycles of AID are required before in vitro fertilization.

To describe a modified simple iris suture for pupillary dilation technique during vitrectomy in cases with a miotic pupil.Four translimbal incisions were created with a sharp straight blade at 1:30,10:30,4:30,and 7:30 o'clock,respectively.The straight needle of 10-0 polypropylene suture and a Sinskey IOL hook was used to displace the pupillary margin toward the limbus.In 3 cases,four sutures caused a 6-mm to 9-mm square-shaped pupil,and the pupil was allowed to return to a smaller size at the end of the operation.It is simple and may reduce postoperative complications.

This study aimed at exploring the application of microtox technology to the evaluation of comprehensive toxicity of Sheng Mai injections.Characteristic parameters of vibrio fischeri (CS234) were measured by methodology inspection under different conditions to optimize the reaction condition with reliable technology.It was the first experiment to accomplish the comprehensive toxicity of Sheng Mai injections from various manufacturers using vibrio fischeri under the target condition.It was found that parameters of the optimum condition contained 0.9 mL recovery liquid volume in each freeze-dried vial and 50 μ L bacteria suspension of each sample,being included in 2 mL solution in aggregate under 10 mins' detection time after adding bacteria suspension with the favorable pH value ranging from 5 to 10 and luminous intensity from 0.8 to 1.2 million within 10 mins.The relative standard deviation values of replication experiment and precision test were all below 15％.Under this optimum detection condition,it was found that the EC50 values were 22.10％,34.10％ and 46.04％,respectively,presenting significant statistical differences (P＜0.05).These results demonstrated that the growth of biological detection standards of Sheng Mai injection was highlighted a long way to go.Besides,the microtox-based fast test for the evaluation of the comprehensive toxicity of Sheng Mai injection showed a prospective application to controlling the quality of different products from manufacturers.

In this research,we chiefly explored a new fast test method--microtox technology to evaluate the comprehensive toxicity of Shen Mai injection.We investigated characteristic parameters of vibrio fischeri (CS234) under different conditions in the pursuit of the optimum test parameters of the reliable method;and then locked the best parameters for Shen Mai injection assay with the products from different manufacturers by microtox fast test.As a result,the optimum reaction condition included 0.9 mL recovery liquid in each freeze-dried vial and 50 μL bacteria suspension of each sample within 2 mL solution in aggregate with 10-mins detection after adding bacteria suspension which pH value ranging from 5 to 10 and luminous intensity from 0.8 to 1.2 million in 10 mins.The relative standard deviation values of replication experiment and precision test were all below 15％.Under this optimum detection condition,it was found that the EC50 values were 35.60％,92.34％ and 146.57％,differing among the samples from three representative drug manufacturers,respectively (P ＜ 0.01).In conclusion,the concentration-effect relationship of Shen Mai injection existed in the toxicity assessment of vibrio fischeri with various ECs0 values from the three manufacturers.These results suggested that biological detection standards of Shen Mai injection presented great growth potential.Microtox-based fast test in the evaluation of comprehensive toxicity of ShenMai injection showed favorable application prospects over controlling the quality of different sources of products.
