OBJECTIVETo explore the clinical effects of Compound Xuanju Capsule (CXC) combined with sildenafil on erectile dysfunction (ED) that progressively fails to respond to sildenafil.

METHODSTotally, 36 ED patients who progressively failed to respond to sildenafil were randomly divided into a trial and a control group of equal number, the former treated with oral CXC at 3 g tid plus sildenafil at 50 mg an hour before sexual activity, while the latter with sildenafil alone at 100 mg an hour before sexual activity. After 2 months of treatment, we compared the patients' scores on IIEF-5 and their partners' scores on Treatment Satisfaction Scale (TSS) between the two groups.

RESULTSThe total rate of erectile function improvement was 94.44% in the trial and 88.89% in the control group (P > 0.05). The IIEF-5 score was 20.888 9 +/- 3.833 1 in the former and 18. 777 8 +/- 4.008 2 in the latter after treatment, significantly higher than 13. 166 7 +/- 3.601 5 and 13. 055 6 +/- 2.775 4 before treatment (P < 0.05). The post-treatment IIEF-5 scores of the patients and the TSS scores of their partners were markedly higher in the trial than in the control group (P < 0.05).

CONCLUSIONCompound Xuanju Capsule combined with sildenafil is effective for erectile dysfunction that progressively fails to respond to sildenafil.

OBJECTIVETo investigate the hemostatic effect of spleen-invigorating, qi-replenishing and blood-containing formula on simvastatin-induced zebrafish hemorrhage model, and to compare with the effect of clearing heat and cooling blood formula.

METHODSZebrafishes from breed A B line were treated with 0.5 µmol/L simvastatin for 24 hours to establish zebrafishes hemorrhage model. Under strict blinded experimental conditions, the above mentioned zebrafishes were then treated with experimental drug of different concentrations at the maximum non-lethal dose. The intervention effect of spleen-invigorating, qi-replenishing and blood-containing formula was comprehensively assessed by examining the main observational parameters, such as bleeding reduction rate and hemostasis rate while referring to additional parameters, such as blood flow, improvement rate of blood flow, velocity of movement, improvement rate of motion, which are characteristics of spleen qi deficiency.

RESULTSWhen the hemostatic effect of experimental drug B1 at the concentrations of 500 and 1 000 µg/ml, zebrafish bleeding rates were 30% and 15%, the hemostatic rate was 60% and 80%, respectively; when the experimental drug B2 at concentration of 500 and 1 000 µg/ml, Zebrafish bleeding rates were 45% and 40%, the hemostatic rate was 40% and 47%, respectively, showing that experimental drug B1 was superior to B2 in terms of decreasing bleeding rate and improving hemostatic effect in zebrafish. In the equal concentration, the experimental drug B1 was superior to B2 in terms of increasing and improving the blood flow of hemorrhagic zebrafish. Promotion and improvement of motion: in equal concentration, experimental drug B1 was superior to B2 in terms of promoting the motion velocity and increasing the improving rate of motion in zebrafish.

CONCLUSIONThe spleen-invigorating, qi-replenishing and blood-containing formula displays a good hemostatic effect on simvastatin-induced hemorrhage of zebrafish. It also boosts the blood flow and motion velocity in hemorrhagic zebrafish, therefore, providing an experimental basis for the treatment of syndrome of spleen failing to control blood by spleen-invigorating, qi-replenishing and blood-containing formula.

Objective: To explore the feasibility and effectiveness of "one-puncture one-needle" transrectal ultrasound (TRUS)-guided prostate biopsy in the prevention of postoperative infections. METHODS: We retrospectively analyzed the clinical data about "one-puncture one-needle" (the observation group) and "one-person one-needle" (the control group) TRUS-guided prostate biopsy performed in the Second People's Hospital of Guangdong Province from January 2005 to December 2015, and compared the incidence rates of puncture-related infection between the two strategies. By "one-puncture one-needle", one needle was used for one biopsy puncture, while by "one-person one-needle", one needle was used for all biopsy punctures in one patient and the needle was sterilized with iodophor after each puncture. RESULTS: Totally, 120 patients received 6+1-core or 12+1-core "one-person one-needle" and 466 underwent 12+1-core "one-puncture one-needle" TRUS-guided prostate biopsy. There were no statistically significant differences between the two groups of patients in age, the prostate volume, the serum PSA level, or the detection rate of prostate cancer (P >0.05). Compared with the control group, the observation group showed remarkably lower incidence rates of puncture-related urinary tract infection (7.5% vs 0.9%, P <0.05), fever (5.0% vs 1.1%, P <0.05), bacteriuria (2.5% vs 0.2%, P <0.05), and total infections (16.7% vs 2.6%, P<0.05) postoperatively. Two cases of bacteremia or sepsis were found in each of the groups, with no significant difference between the two. CONCLUSIONS "One-puncture one-needle" TRUS-guided prostate biopsy can effectively prevent puncture-related infections.

ObjectiveTo explore the effect of Modified Dahuang Zhechong Granule (MDZG) on the development and maturation of epididymal sperm in experimental varicocele (VC) rats.

METHODSSixty SD male rats were randomly divided into six groups of equal number, sham operation, VC model, Aescuven forte, and low-, medium- and high-dose MDZG. The model of left VC was made by the Turner method in all the rats except those of the sham operation group, followed by treatment with 0.9% normal saline for the animals in the sham operation and VC model groups, Aescuven forte tablets at 54 mg per kg of the body weight for those in the Aescuven forte group, and MDZG at 0.6, 1.2 and 2.4 g/ml for those in the low-, medium- and high-dose MDZG groups, all administered intragastrically qd for 8 successive weeks. Then, all the rats were sacrificed and their left epididymides harvested for examination of the quality of the epididymal sperm and the local microscopic and ultrastructural changes of the epididymal tissue.

RESULTSThe VC model rats showed significant apoptosis of the epididymal sperm cells, interstitial edema, microvascular dilatation, degeneration and degeneration of the epithelial cells, degeneration of some principal cells and basal cell vacuoles, and immature spermatids in the lumen. Sperm motility was significantly increased in the Aescuven forte and low-, medium- and high-dose MDZG groups as compared with the VC models (P <0.01). Both sperm concentration and motility were markedly higher in the high-dose MDZG than in the Aescuven forte group (P <0.05). Remarkable apoptosis of epididymal sperm cells was observed in the microenvironment of sperm development in the VC models, which exhibited no statistically significant difference from that in the rats of the medium- and high-dose MDZG groups.

CONCLUSIONSExperimental varicocele induced local apoptosis of epididymal sperm cells, interstitial edema and microvascular dilatation in the rat epididymis, while Modified Dahuang Zhechong Granule could improve the stability of epididymal sperm maturation and contribute to their development.
