Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

Abstract? AlM: To evaluate macular thickness and macular volume changes in people with diabetes mellitus but no significant decrease of visual acuity.?METHODS:A total of 87 eyes were collected in diabetic group. According to the international stage of diabetic retinopathy, these cases were divided into two subgroups:DR0 stage 54 eyes and DR1 stage 33 eyes. All the cases were received optical coherence tomography (OCT) scan in macular area;the scanning model is 512× 128; recording macular average thickness and macular volume, and compared with healthy subjects.? RESULTS: Macular average thickness and macular volume were higher in DR1 group than those in DR0 stage and control group, and differences were having statistical significance. But DR0 group and control group differences of the two indexes were not statistically significant.? CONCLUSlON: With the aggravation of diabetic retinopathy, the macular thickness tends to be thicken. Although without obvious visual loss, there have been slight morphological changes. Using OCT scan can find fundus changes earlier in patients with diabetes mellitus, and provide clinical basis for both early diagnosis and treatment.

The essential medium of B115 composed of 1% tryptone, 0.25% yeast extract and 0.5% sodium chloride was determined by using an orthogonal design. The orthogonal design was also employed in testing the optimum additions. It was composed of 0.1%(NH_(4))_(2)SO_(4),1.4%K_(2)HPO_(4), 0.6% KH_(2)PO_(4) and 0.1% (Na_(3)C_(6)H_(5)O_(7)). The yield of B115 cultured in optimum medium was compared with the one in essential medium. Statistic analysis showed that the growth of B115 was most significantly improved by adding K~(+)、NH~+_(4) and (Na_(3)C_(6)H_(5)O_(7)) to essential medium. The antibacterial effect of Bacillus subtilis strain B115 on pathogenic Aeromonas was studied. The results showed different antibacterial effects of B115 on different aeromonads. There were obvious antibacterial effects on BSK-10 and CL990920, while no effect on the growth of TL970424.

BACKGROUND: Good neurological outcome after cardiac arrest (CA) is hard to achieve for clinicians. Experimental and clinical evidence suggests that therapeutic mild hypothermia is beneficial. This study aimed to assess the effectiveness and safety of therapeutic mild hypothermia in patients successfully resuscitated from CA using a meta-analysis. METHODS: We searched the MEDLINE (1966 to April 2012), OVID (1980 to April 2012), EMBASE (1980 to April 2012), Chinese bio-medical literature & retrieval system (CBM) (1978 to April 2012), Chinese medical current contents (CMCC) (1995 to April 2012), and Chinese medical academic conference (CMAC) (1994 to April 2012). Studies were included if 1) the study design was a randomized controlled trial (RCT); 2) the study population included patients successfully resuscitated from CA, and received either standard post-resuscitation care with normothermia or mild hypothermia;3) the study provided data on good neurologic outcome and survival to hospital discharge. Relative risk (RR) and 95% confidence interval (CI) were used to pool the effect. RESULTS: The study included four RCTs with a total of 417 patients successfully resuscitated from CA. Compared to standard post-resuscitation care with normothermia, patients in the hypothermia group were more likely to have good neurologic outcome (RR=1.43, 95% CI 1.14–1.80, P=0.002) and were more likely to survive to hospital discharge (RR=1.32, 95% CI 1.08–1.63, P=0.008). There was no significant difference in adverse events between the normothermia and hypothermia groups (P>0.05), nor heterogeneity and publication bias. CONCLUSION: Therapeutic mild hypothermia improves neurologic outcome and survival in patients successfully resuscitated from CA.
