The incidence rate of erectile dysfunction (ED) is reportedly as high as 30-90% after radical prostatectomy for prostate cancer, which seriously affects the patients' quality of life. Penile rehabilitation is defined as the use of any drug or device at or after radical prostatectomy to maximize erectile function recovery. A variety of treatment options are available for post-prostatectomy ED patients, including oral phosphodiesterase 5 inhibitors (PDE5I) , intracorporal injections, vacuum erection device, and penile prosthesis. This article presents an overview of the currently used methods for the drug treatment and penile rehabilitation of the ED patients after radical prostatectomy. It seems proper to recommend daily use of a vacuum erection device plus oral PDE5I in the early postoperative period. For those who fail to respond to this therapy, intraurethral alprostadil, intracorporal injections, or a penile prosthesis could be considered.

Objective To determine the characteristics and the best parameters of the retinal nerve fiber layer (RNFL) thickness measured by optical coherence tomography (OCT) in the early diagnosis of primary open angle glaucoma (POAG). Methods The thickness of RNFL was quantified by OCT (Carl Zeiss Meditec, Stratus OCT3000 version 3, RNFL3.4) in 71 POAGs(119 eyes) and 76 controls(148 eyes). Results The 9 OCT parameters with the largest AUCs and asymptatic significance less than 0.05 in ROC curve in the early diagnosis of primary open angle glaucoma (POAG) were thickness of 6, 7, 11 o’clock position, inferior, superior, average thickness, inferior maximum, superior average, inferior average. Conclusion In early stage of glaucoma, the thickness of RNFL measured by OCT provides a new index for the diagnosis of glaucoma. The best parameters seem to 6, 7, 11 o’clock position, inferior, superior, average thickess, inferior maximum, superior average, inferior average.

Objective To investigate the effect of surgical intervention combined with steroid therapy on infantile hepatitis(INS) with persistent jaundice.Methods Twenty-two patients (19 males,3 females,aged 2-6 months) with persistent jaundice(therapy group) were admitted into hospital in the period of Jan.2007-Dec.2008.The patients were performed with surgical intervention after they were confirmed with diagnosis as INS.Then,sodium chloride,gentamicin and Dexamethasone were used to irrigate the biliary tract during and after the operation for 14 days.Three days after operation,20 mg,15 mg,10 mg,5 mg of methylprednisolone were administered intravenously to the patients every 3 days,followed with 4 mg/(kg?d) prednisone by oral for 2-3 months.The 17 cases of INS with persistent jaundice were treated with medicine as control(control group).By following-up,the jaundice free and 2 years survival rate of 2 groups were compared by counting the cases of jaundice free and recording the survival time.Results Two cases of 22 patients performed with surgical intervention were diagnosed as biliary atresia and others were INS,90.0% patients were free of jaundice in surgical intervention combined with steroid therapy group,which was higher than that in control group(52.9%,P

Objective To discuss the quantitative diagnosis of stagnation of Qi and blood stasis syndrome in chronic prostatitis. To make diagnosis chart and ensure diagnosis threshold level which provide statistics evidence for syndrome differentiation of TCM. Methods By the statistical ways, 168 cases of chronic prostatitis belong to stagnation of Qi blood and stasis syndrome and 198 cases of non-stagnation of Qi and blood stasis syndrome were investigated. To make a diagnosis chart and ensure diagnosis threshold level by applying the method of the maximum likelihood discriminatory analysis. Results The quantitative diagnosis chart was made and diagnosis threshold level was 26. According to the retrospective and prospective test, its sensitivity, especially degree, coincidence rate, error rate and positive likelihood ratio were 94.64%, 88.89%, 91.53%, 8.47%, 8.52 and 94.28%, 90.32%, 92.42%, 7.58%, 9.74. Conclusion The indexes of the quantitative diagnosis have good objectivity. According to the retrospective and prospective test, the diagnosis chart was proved to be practical.

0.05). CONCLUSION The secar of oropharynx can be regarded as a predictive index for OSAHS severity and guideline for operation, but the change of secar after operation can not be used as a predicitive index for therapeutic effectiveness.

To explore a new way of constructing bioartificial renal tubule assist device (RAD) in vitro and its function of transporting sodium (Na(+)) and glucose and to evaluate the application of atomic force microscope in the RAD construction, rat renal tubular epithelial cell line NRK-52E was cultured in vitro, seeded onto the outer surfaces of hollow fibers in a bioreactor, and then cultured for two weeks to construct RAD. Bioreactor hollow fibers without NRK-52E cells were used as control. The morphologies of attached cells were observed with scanning electron microscope, and the junctions of cells and polysulfone membrane were observed with atomic force microscope. Transportation of Na(+) and glucose was measured. Oubaine and phlorizin were used to inhibit the transporting property. The results showed that NRK-52E cells and polysulfone membrane were closely linked, as observed under atomic force microscope. After exposure to oubaine and phlorizin, transporting rates of Na(+) and glucose were decreased significantly in the RAD group as compared with that in the control group (P<0.01). Furthermore, when the inhibitors were removed, transportation of Na(+) and glucose was restored. It is concluded that a new RAD was constructed successfully in vitro, and it is able to selectively transport Na(+) and glucose.

AIM: to assess the effectiveness of a combined procedure ( pars plana vitrectomy with temporary keratoprosthesis, vitreoretinal surgery, and penetrating keratoplasty). in the complicated cases and the risk factors for the surgical failure.METHODS: Restrospectively reviewed charts of patients who underwent penetrating keratoplasty in combination with vitreoretinal surgery between 1990 and 2005, with a follow-up of 3mo to 9a. Analysis was focused on ocular history, indications for surgery, visual acuity (VA), anatomic results, and complications.RESULTS: 18 eyes had light perception or VA of hand motions only. The best-corrected VA improved during the first 3mo, increased in 72.2% of all eyes, remained unchanged in 27.78%, and no decreased. In 3 of 18 eyes (16.67%), VA was better than finger counting and hand motions, and nine eyes(50%) showed useful vision (0.05) postoperatively. 10 eyes showed a clear corneal graft (55.56%). 2 eyes needs the second keratoplasty, Bullous corneal edema was evident in 3 eyes, band keratopathy was evident in a 3 eyes. 10 patients were observed for more than 2a;6 had a clear graft (60%). Two eyes (11.11%) had silicone oil-corneal endothelium contact and all of these grafts failed.CONCLUSION: Although the functional outcome of a combined procedure is limited by primary and secondary tissue destruction, preserving ambulatory vision is possible and thus improves the quality of life, at least in patients with single remaining eyes.

Objective To study the mechanism of mast cell increase in cellular leiomyoma of uterus.Methods Tissue sections from 30 cases of cellular leiomyoma of uterus,15 cases of leiomyosarcoma and 30 cases of ordinary leiomyoma were studied using immunohistochemical double labeling techniques.The expression of mast cell tryptase ahd Ki-67 as well as mast cell tryptase and chemotactic factors RANTES,Eotaxin,monocyte chemoattractant protein-1(MCP-1),transforming growth factor-? (TGF-?)were double immunostained.Results Ki-67 in mast cells was rarely expressed in each group. Expressions of regulate upon activation normal T cell expressed and secreted(RANTES),Eotaxin and TGF-? in cellular leiomyoma were 78%,89%,91%,respectively.They were all higher than those in ordinary leiomyoma and leiomyosarcoma(P

0.05). After dividing the patients into early-onset and late-onset subgroups, there were significant differences of DRD4 genotype and allele frequency between early-onset patients and controls (P0.05). Conclusion The results suggested that the polymorphism of DRD4 receptor gene may be associated with early-onset OCD. The 3/4 genetype may be the risk factor of early-onset OCD. Early-onset and late-onset OCD may have different etiology.
