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 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 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 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.

OJECTIVETo observe the effect of tianma gouteng decoction (TGD) on the endothelial function and the renal protein expression of spontaneously hypertensive rats, and to analyze its possible mechanism.

METHODSTotally 18 6-week-old SHR were randomly divided into 3 groups according to randomized block design, the SHR control group, the TGD group, and the captopril group, 6 in each group. Meanwhile, Wistar Kyoto (WKY) rats of the same age were recruited as a WKY control group. Rats in the TGD group were administered with TGD at the daily dose of 10. 260 g/kg. Rats in the captopril group were administered with captopril at the daily dose of 3. 375 g/kg. 2 mL/100 g distilled water was administered to rats in the SHR control group and the WKY control group. All medication was performed by gastrogavage once per day till rats were 24 weeks old. Changes of blood pressure were measured once per two weeks. The relaxation of the thoracic aorta and the superior mesenteric artery was determined by vascular ring in vitro to reflect the endothelial function. The total renal protein was separated by two-dimensional electrophoresis (2-DE). The significantly deviated protein was verified by Western blot.

RESULTS(1) Compared with the SHR control group, blood pressure was significantly lowered in rats (10 - 24 weeks old) of the captopril group (P <0.01, P <0.05). The hypotensive effect of TGD was obvious at the beginning of hypertension (10 -12 weeks) (P <0. 01). But along with the progression of hypertension, its hypotensive effect was not obvious (P>0. 05). (2) Compared with the SHR control group, the relaxation of the superior mesenteric artery was obviously improved in the TGD group (P <0. 05); the relaxation of the thoracic aorta and the superior mesenteric artery was obviously superior in the WKY control group (P <0. 01, P <0. 05). But there was no statistical difference in each relaxation index between the captopril group and the SHR control group (P >0. 05).(3) RESULTS: of 2-DE found 16 significantly differential renal protein, mainly involved nitric oxide (NO) system, oxidative stress, and cytoskeleton-related proteins. Results of Western blot showed that TGD could significantly improve expressions of Cu-Zn superoxide dismutase (SOD), N(G, N(G)-dimethylarginine dimethylaminohydrolase 2 (DDAH2), and pterin-4-alpha-carbinolamine dehydratase 1 (PCBD1) (P <0. 05).

CONCLUSIONGTD could protect the endothelial function of the superior mesenteric artery in SHR, and its intervention mechanism of hypertension induced early renal injury might be relevant to regulating the NO system and antioxidative stress.

Objective To investigate rite effects of loag-term exposure to low-level sevoflurane on reproductive function in mice.Method F0ny male ICR mice,aged 60 d,weighlag 20-25 g,were randomly divided into 4 groups(n=10 each):control group received no sevoflunme(C);group S1-3 were exposed to 0.003%.0.01% and 0.03% sevoflurane 2 h per day for 5 consecutive days per week for 8 weeks respectively. The mice were then sacrificed at the end of the 8 weeks.The testes and epididymis were emoved and sampled for determination of the activities of total lactic dehydregenase(LDH)and lactic dehydrogenase-X(LDH-X),and the motility rate,amount,and aberration rate of sperm.Testicular uhrastructure were observed by transmission electron microscopy.Results The sperm motifity nne were significantly lower.the sperm aberration rate higher and the activity of LDH-X lower in group S3 than in group C(P<0.05),but there was no significant difference in the above parametem between group SI and group S2(P>0.05).The pathology changed of testes occurred only in group S3 among the 3 groups.Conclusion Long-term exposure to 0.03% sevoflurane can result in the abnormality of the reproductive function in male mice but exposure to≤0.01%sevoflurane dose not.
