To investigate the clinical efficacy of Shuganyiyang Capsule combined with conventional Western medicine (tamsulosin hydrochloride sustained release tablets + prostat tablets) for the treatment of type III prostatitis complicated by erectile dysfunction (ED).Eighty patients with type III prostatitis complicated by ED were equally randomized to an experimental and a control group, the former treated with Shuganyiyang Capsule combined with tamsulosin hydrochloride sustained release tablets and prostat tablets, while the latter with tamsulosin hydrochloride and prostat only, both for 8 weeks. Then the prostatitis symptoms, erectile function and psychological conditions of the patients were evaluated using NIH-CPSI, IIEF-5, and hospital anxiety and depression scale (HADA and HADD) respectively. The rates of recovery, excellence, effectiveness and ineffectiveness were calculated.The scores on NIH-CPSI, IIEF-5, HADA and HADD obtained at 4 and 8 weeks after treatment showed statistically significant differences between the two time points as well as from the baseline (P0.01). At 8 weeks, the scores on NIH-CPSI, IIEF-5, HADA and HADD were 6.83 +/- 4.96, 21.03 +/- 2.54, 6.05 +/- 1.62, and 5.35 +/- 3.30 in the experimental group, as compared with 7.55 +/- 4.89, 17.68 +/- 4.15, 6.88 +/- 2.45, and 7.85 +/- 3.77 in the control (P0.05). The rate of effectiveness was significantly higher in the experimental than in the control group (90% [36/40] vs 70% [28/40], P0.05).Shuganyiyang Capsule combined with conventional Western medicine, such as alpha blockers and galenica, produces definite effect on chronic prostatitis complicated by ED, improves the psychological conditions of the patient, and enhances the therapeutic efficiency of chronic prostatits.

To establish a Wistar rat model of chronic abacterial prostatitis (CAP) by injecting purified prostate protein and Freund's complete adjuvant, and to study the influence on the morphology and proinflammatory expression.Male rats were injected with the Pertussis-Diphteria-Tetanus vaccine into the abdominal cavity and purified prostate protein and Freund's complete adjuvant intradermally at 0 and 30 days. At 60 days, the rats were sacrificed, and then the prostate specimens were observed, under the light microscope and electron microscope, and the changes of proinflammatory expression was observed too, using PCR technique.The products of proinflammatory expression, such as eotaxin, iNOS and IL-4 increased markedly. The change of chronic inflammation was shown by light microscope and electron microscope.Chronic prostatitis is associated with autoimmunity.

To observe the morphological and molecular biological peculiarities of the experimental autoimmune prostatitis (EAP) rat model made by SC purified prostate protein twice with immune adjuvant.Male rats were intradermally immunized with a saline extract of male rat prostate glands (RPG) in Freund's complete adjuvant (FCA) and Pertussis-Diphtheria-Tetanus vaccine 0.5 ml i.p. at the 0 and 30th day, and the concentrations of the extract were respectively 5 mg/ml, 10 mg/ml and 15 mg/ml. At the 45th day, the rats were sacrificed and the morphological and molecular biological changes of the prostate specimens were observed to determine the effective concentration of RPG for a successful model.The expression of inflammation genes such as TNF-alpha, IL-1beta, IL-2 and iNOS obviously increased in the high-dosage model group; LM, EM and in situ hybridization revealed appearant chronic inflammation response, but this was not the case in the other two dosage groups.15 mg/ml RPG mixed with FCA (1:1) 1.0 ml SC with Pertussis-Diphtheria-Tetanus vaccine 0.5 ml i.p. was an effective dosage for the successful model in our experiment.

To investigate the effect of immunological orchitis on spermatic specific enzyme and fertility.Experimental allergic orchitis (EAO) model of guinea pigs was duplicated. The histological and morphological changes of spermatic acrosomal protease and hyaluronidase, lactate dehydrogenase, sperm in epididymis and testes were observed by means of enzyme kinetical spectrophotometry and gelatin fixation of substrate thin membrane.The activity of acrosomal protease, hyaluronidase and spermatic cytoplasmic lactic dehydrogenase in the epididymis acrosomal enzyme system became low, and so did the quality of sperm in epididymis. Remarkable morphological changes of spermatogenic cells developed in the convoluted seminiferous tubules.EAO remarkably affects the fertility of male guinea pigs. The orchis and epididymal sperms might be the sites of action.
