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.

Objective To study the severity of systemic inflammatory response to type B epidemic encephalitis and blood tumor necrosis factor complicated with respiratory failure.Methods Fourteen children with type B epidemic encephalitis were divided into two groups;6 cases in group one with respiratory failure were given mechanical ventilation and the other 8 cases had normal respiration.Breat-hing pattern,respiratory rate,GCS scores,daily dosage of sedatives were observed before endotracheal intubation;while heart rate,temperature,WBC,CRP,TNF were measured.Results Patients in respiratory failure group were given a small dosage of Luminal;there was no significant difference in GCS between two groups treated with compound Wintermin.The heart rate,temperature,WBC,CRP,TNF levels in respiratory failure group were significantly higher than those in normal respiratory group.Conclusions The severity of systemic inflammatory response is more severe in epidemic type B encephalitis with respiratory failure than the controls.Significant increase in blood TNF may be an important factors to cause peripheral respiratory failure.

Objective To investigate the pathogenesis of age-related cortex and nuclear cataract.Methods The levels of transforming growth factor-?_2 (TGF-?_2)mRNA,proliferating cell nuclear antigen (PCNA),ratio of Bcl-2/Bax,fibronection (FN),vimentin and the density of lens epithelial cells (LECs) were measured and compared among age-related nuclear cataract,cortex cataract and normal LECs.Results The ratio of TGF-?_2 mRNA expression/?-actin expression,the levels of PCNA protein,Bax and Bcl-2 in age-related nuclear cataract(0.16?0.02,16.01,15.97, 16.97)and in cortex cataract (0.27?0.01,1.98,16.93,1.44) were significantly different from those in normal LECs(0.15+0.02,2.43,16.84,6.12),all P

OBJECTIVE: To study the efficacy of treatment with microsurgery in combination with local injection of type A botulinum toxin for vocal process granuloma. METHOD: 28 patients with vocal process granuloma received endotracheal intubation under general anesthesia. The lesion was removed with micro-scissor and CO2 laster under a self-retaining laryngoscope and microscope. The incision and mucous membrane surrounding the wound was closed with 8-0 absorbable suture. 4-point injection of botulinum toxin type A 8-15 u was then performed along the thyroarytenoid muscle and arytenoid muscle of the same side. Postoperative medication was administered based on disease causes. RESULT: All patients experienced vocal cord dyskinesia of the injected side 2-3 days after surgery. At 1 month after the surgery, wound healing was good in all the 28 patients, and the vocal cord movement was limited at the injected side. At 3 months, movement of the bilateral vocal cords was normal, and the vocal cord process mucosa was smooth. Patients were followed up for more than a year, and only one patient had recurrence in 2 months after surgery. The cure rate was 96. 4%. CONCLUSION Combination of laryngeal microsurgery and type A botulinum toxin local injection can shorten the treatment course of vocal process granuloma.

The fermentation of Bacillus cereus DLSL-2 was investigated through single-factor test. The optimized fermentation conditions are: temperature 30℃,initial pH 7.0,250 r/min. Uniform design was used in shaking flask to optimize the fermentation medium of bacillus cereus . The most suitable medium was identified as follows:4.88% defated soybean power ,1.45% maize starch, 0.106% K 2HPO 4, 1.78% yeasts extract, 5.6% inoculum. the optimized medium allowed the B.cereus biomass concentration to be increased from 3.2?109 cfu/mL to 7.1?109 cfu/mL.

A new flavonoid glycoside, (-)-2S-8-methyl-5,7,4'-trihydroxyflavanone-7-O-β-D-glucopyranoside (1), along with five known ones, quercetin-3-O-(2"-galloyl)-α-L-arabinoside (2), kaempferol-3-O-α-L-arabinoside (3), guaijaverin (4), trifolin (5) and hyperin (6), was isolated from the leaves of Eucalyptus robusta. Their structures with absolute configurations were elucidated by NMR, HR-ESI-MS, CD spectra data and physicochemical methods. In addition, 2-6 were isolated from E. robusta for the first time.

To investigate the role of ligustrazine on relaxation of the isolated rabbit corpus cavernosum tissue in vitro, the effects of ligustrazine on the corpus cavernosum were observed by using experimental method of smooth muscle strips. Concentration-responses to phenylephine (PE) and KCl were recorded. The results showed that ligustrazine concentration-dependently depressed the contraction response of smooth muscle strips induced by PE. The maximum percentage relaxation of cavernosal strips by ligustrazine was 74.1% +/- 6.2% (compared with control: 21.9% +/- 5.6%, P < 0.01). Ligustrazine concentration-dependently reduced the amplitude of the contraction induced by cumulative doses of PE or KCl, shifted the cumulative concentration response curves of PE and KCI to the right and depressed their maximal responses. It was concluded that ligustrazine could significantly relax the cavernosal muscle contraction induced by PE in vitro. The results suggested that ligustrazine inhibited calcium ion influx.
