Objective To study the value of the preoperative detrusor contractility to the outcome assessment of prostatectomy for benign prostatic hyperplasia (BPH).Methods A total of 109 patients with BPH were analyzed.Their ages ranged from 62 to 83 years with a mean of 71 years.All patients underwent urodynamic study to confirm a diagnosis of BOO preoperatively.Further more, their BOO was not caused by nervous, endocrine or other diseases.Pateints were divided into two groups based on maximum detrusor contractility.Group Ⅰ (n =61, BPH with maximum detrusor contractility ≥ 40 cm H2O, 1cm H2O =0.098 kPa) underwent TURP or open surgery, respectively.Group Ⅱ (n =48, BPH with maximum detrusor contractility ≤ 20 cm H2O ) underwent TURP and suprapubic punctural cystostomy simultaneously,the bladder fistula was kept open continuously for at least two weeks postoperatively.The difference in outcome between the two grous was assessed by using urodynamic parameters including maximum detrusor contractility, Qmax and residual urine at one and three months postoperatively respectively.Student's t-test was used to compare the result for normally distributed data and Wilcoxon's signed-ranks test for skewed data in this study.Results There was significant difference in preoperative maximum contractility, Qmax between group Ⅰand groupⅡ (78.4 ±37.0 cm H2O) vs (19.2 ±5.4 cm H2O)(P<0.01), (7.6±2.2 ml/s) vs (2.5 ± 1.1 ) ml/s (P < 0.05) respectively.Although there was significant difference at one month postoperatively in Qmax (17.4 ±2.9)ml/s vs (12.5 ±2.0)ml/s (P<0.05), no significant difference was found in Qmax between the two groups after three months ( 18.3 ±2.8 ml/s) vs ( 15.2 ± 1.8)ml/s (P > 0.05).Conclusions The Qmax may improve and the impaired detrusor recovered gradually after the BOO was removed.Performing an operation on patients with BOO accompanied with detrusor underactivity may be useful to recover detrusor contractility.

ObjectiveTo study the relationship between EphA2 and laryngeal carcinoma angionegesis.MethodsImmunohistochemical staining was used to determine the expression of EphA2 and CD34 in 20 normal squamous epithelium tissues and 50 laryngeal carcinoma.The relationship between EphA2 expression and Microvascular density was analyzed bg Spearman correlation and linear regression.ResultsThe MVD in laryngeal carcinoma (54.89 ± 13.67) was significantly higher than that in normal squamous epithelial tissues ( 17.15 ± 5.21 ) ; The EphA2 in laryngeal carcinoma(4.56 ± 1.38) was significantly higher than that in normal squamous epithelial tissues ( 2.49 ± 1.23 ) ( t =16.721,5.847,all P < 0.05 ).There was significant positive linear correlation between EphA2 and MVD in laryngeal squamous cell carcinoma(P < 0.01 ).ConclusionEphA2 may correlate with angionegesis in laryngeal squamous cell carcinoma.

Objective: To observe the preventive effect of taurine on alcoholic liver damage in rat.Methods: The model was induced by filling stomach with alcohol, and the treatment groups were given two different concentrations of taurine, and the control group was given 0.9%NS, then we measured the blood triglycerides (TG), and the pathological changes of liver quantitatively.Results: Two different le-vels of taurine can significantly decrease the level of TG and ameliorate the liver damage of rats (P0.05), and the 5% taurine group can also decrease the mean arterial pressure (P
