Objective To explore the safety and efficacy of testosterone replacement therapy in patients with male late-onset hypogon-adism and Mild-to-moderate benige prostate hyperplasia. Methods Forty-three patients diagnosed as male late-onset hypogonadism and Mild-to-moderate benige prostate hyperplasia were selected,of which 28 patients were assigned to Eleven acid testosterone (40 mg each time, after a meal,2 times per day) ,other patients were in the control group. The patients were followed for 12 months and their data about digital rectal inspection,size of the prostate,IPSS score,maximum urinary flow rate ( Qmax) ,AMS clinical symptom score,serum testosterone level, serum PSA level,RBC hematocrit ( HCT) ,and other indicators were collected. Results Twelve months After testosterone replacement thera-py,both the prostate volume of treated and control groups were not significantly changed(P>0. 05). IPSS score and maximum urinary flow rate in treatment group were improved significantly(P<0. 05),but the control group showed no statistically significant changes(P>0. 05). Baseline AMS clinical symptom score and blood testosterone level were similar between treatment and control group (P >0. 05). Twelve months after treatment,the blood testosterone level of the treatment group reached the normal range,and the AMS clinical symptom scores de-creased significantly (P<0. 05). However,none indexes of control group significantly changed after the treatment (P>0. 05). Conclusion Testosterone replacement therapy in patients with male late-onset hypogonadism and the Mild-to-moderate benige prostate hyperplasia is safe and effective.

OBJECTIVETo survey the current situation of hypertension among "three minority ethnic groups" in Inner Mongolia Autonomous Region.

METHODSHypertension epidemiological survey among Three Minority Ethnic Groups and Han nationality aged ≥ 18 years was performed from June to December 2010.

RESULTSThe prevalence rate of hypertension among the surveyed population was 29. 4% (630/2 146) ( standardized prevalence was 34.6%). The prevalence rate of hypertension in male was 33. 8% (359/1 062) ( standardized prevalence was 39.9%), and the prevalence rate in female was 25.0% (271/1 084) (standardized prevalence was 26.6%) and the prevalence rate in male was higher than in female (P < 0.01).

BACKGROUND:There is a high morbidity after spinal cord injury, and the therapeutic strategy is limited to early surgical intervention, medication and post-treatment exercise that only can improve the motor function slightly. However, there is no effective cure method. OBJECTIVE:To study the effect of partition-type spinal cord catheter combined with bone marrow stromal stem cels on T8 spinal cord transection damage in rats. METHODS:Fifty rats were randomized into five groups (n=10 per group): group I, T8 spinal cord transection (5 mm) was made in rats with no treatment; group II, the partition-type tube was inserted into the injured site after modeling; group III, partition-type tube combined with bone marrow stromal stem cels was implanted into the injured site after modeling; group IV, partition-type tube combined with polyglycolic acid fibers was implanted into the injured site after modeling; group V, partition-type tube combined with bone marrow stromal stem cels and polyglycolic acid fibers was implanted into the injured site after modeling. RESULTS AND CONCLUSION:At 2 and 12 weeks postoperatively, Basso, Beattie and Bresnahan scores were significantly higher in the groups III and IV than the groups I, II, IV (P < 0.05). At 12 weeks postoperatively, the latency of motor evoked potential below the injury plane was significantly decreased in group V compared with groups I, II, III, IV (P < 0.05). Immunohistochemical results displayed that in the groups III and V, regenerated nerve fibers grew positively and arranged orderly among the tubes, and there was no obvious winding phenomenon. Under transmission electron microscopy, a certain number of myelinated nerve fibers were found as bridges among groups. These findings indicate that the partition-type chitosan tube combined with bone marrow stromal stem cels has a good connection with the injured spinal cord a good connection to restore part of electrophysiological properties, accelerate the axon regeneration, recover the motor function, thereby providing a new direction for the treatment of spinal cord injury.

Objective To study the pelvic fascia related to pelvic autonomic nerve and detect the anatomical localization of pelvic autonomic nerve by marker in adult male.Methods Twelve pelvises of adult male harvested from cadavers were studied by dissection.Results Hypogastric nerve was embedded in the posterior leaf of the visceral pelvic fascia.Pelvic plexus was situated between vesicohypogastric fascia and visceral fascia.Pelvic nerve branch of seminal vesicle and prostate was located at the anterolateral part of Denonvilliers fascia.Sacral promontory,ureter,junction of Denonvilliers fascia,visceral fascia and seminal vesicle could be regarded as anatomical markers for pelvic autonomic nerve.Conclusion The anatomical characteristics of pelvic autonomic nerve can be used for protecting and isolating pelvic autonomic nerve in total mesorectal excision of adult male.

Objective To explore the effects and molecular mechanisms of suberoylanilide hydroxamic acid (SAHA) on ovarian carcinoma. Methods (1)Two groups of ovarian carcinoma cell lines (SKOV3 and SKOV3/DDP, HO8910 and HO8910-PM) were exposed to SAHA (1, 3, 5 and 7μmol/L SAHA,group 1-group 4). CCK-8 method was employed to eval-uate the inhibitory effects of SAHA.(2)Ovarian cancer cell lines treated with SAHA (2 or 5μmol/L SAHA) were used as 1 and 2 groups. Flow cytometry was performed following staining with Annexin V-FITC and PI for cell cycle and apoptosis.(3) Reverse transcription polymerase chain reaction (RT-PCR) and Western blot assay were used to assess the mRNA and pro-tein expression levels of phenotypic correlation factor. Results (1)After 48 h of SAHA treatment,the OD value of SKOV3, SKOV3/DDP,and HO8910 showed a trend of gradually reduce (P<0.05).(2)The apoptotic rates were significantly higher in SAHA 1 and SAHA 2 groups than those of control group (P<0.05). Compared with control group, after 48 h of SAHA treat-ment,S phase and G2/M phase of SKOV3 and SKOV3/DDP cells increased;G0/G1 phase of HO8910 and HO8910-PM cells increased in SAHA 1 and 2 groups (P<0.05).(3)The expression levels of CyclinB1 and Cdc2 (p34) mRNA were significant-ly lower in SAHA 1 and 2 groups than those of control group,while the expression levels of Caspase-3,p21 and p53 mRNA expression were significantly higher in SAHA 1 and 2 groups than those of control group. Furthermore,the expression of Ac-Histone H3,Ac-Histone H4,p53 protein were markedly improved,and CyclinB1,Cdc2(p34) protein decreased in SAHA 1-4 groups. Conclusion SAHA may suppress cell growth, induce apoptosis and cause cycle arrest in ovarian carcinoma cells by promoting histone acetylation or modulating their phenotype-related proteins of Caspase-3, p53, CyclinB1 and Cdc2(p34).
