Effect of Modified Wuzi Yanzong Pill () on Tip60-Mediated Apoptosis in Testis of Male Rats after Microwave Radiation / 中国结合医学杂志

OBJECTIVE@#To investigate the effect of a modified Wuzi Yanzong Pill (, WZYZP) on the male rats' testis after microwave radiation, as well as its potential mechanism.@*METHODS@#Forty-five male rats were randomly assigned to three groups: the control group, the radiation group, and the WZYZP group. The rats in the radiation group and WZYZP group were exposed to microwave radiation for 15 min once, while the rats in the control group were not exposed to any radiation. The rats in the WZYZP group were given a modified of WZYZP by gavage daily for 7 days. Apoptosis in the testis was evaluated using terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay. Histopathological alterations of the testis were observed by haematoxylin-eosin (HE) staining. Tat-interactive protein, 60kD (Tip60) and p53 expressions were determined by Western blotting.@*RESULTS@#The apoptosis index (AI) in the radiation group was higher than that of the WZYZP group and control group on day 1 (D1), day 7 (D7) day 14 (D14) after radiation (P<0.05). The seminiferous tubules were of normal morphology in the control group. In the radiation group, the partial seminiferous tubules were collapsed, basement membranes of the seminiferous epithelia became detached. WZYZP could restore the morphological changes. There was no expression of Tip60 among the three groups on D7 and D14. The expression of p53 was higher in the radiation group than in the control group (P<0.05). WZYZP could down-regulate the rising p53 induced by radiation on D7 and D14 (P<0.05).@*CONCLUSION@#A modified WZYZP may affect germ cells, and its protective effects may partly result from its ability to intervene in Tip60 mediated apoptosis.

Yijingfang for the treatment of asthenospermia: A randomized controlled clinical trial / 中华男科学杂志

Objective@#To investigate the clinical therapeutic effects of Yijingfang, a Chinese medicinal liquid, on asthenospermia.@*METHODS@#We randomly divided 450 asthenospermia patients into a treatment group (n = 300) and a control group (n = 150), the former treated with Yijingfang once half a dose, bid, and the latter with Wuziyanzong Pills (9 g, bid) + L-carnitine oral liquid (10 ml, bid), both for 3 months. Before and at 1, 2, and 3 months after medication, we compared the semen volume, sperm concentration, percentages of progressively motile sperm (PMS) and total motile sperm (TMS), and semen liquefaction time between the two groups of patients.@*RESULTS@#No statistically significant difference was observed in the semen parameters between the treatment and control groups before medication (P >0.05). In comparison with the baseline, the treatment group showed significant differences at 1, 2, and 3 months after medication in sperm concentration (［35.96 ± 8.50］ vs ［49.66 ± 10.91］, ［55.21 ± 11.46］, ［74.90 ± 13.07］ ×10⁶/ml, P 0.05) or semen liquefaction time (［32.31 ± 8.15］ vs ［31.68 ± 3.14］, ［30.38 ± 3.44］, and ［30.86 ± 2.42］ min, P >0.05); the control group exhibited similar results at the three time points in sperm concentration (［36.85 ± 6.88］ vs ［40.53 ± 8.32］, ［47.51 ± 12.73］, and ［56.14 ± 11.98］ ×10⁶/ml, P 0.05) or semen liquefaction time (［30.25 ± 5.20］ vs ［29.36±4.25］, ［28.21±3.26］, and ［28.33±3.59］ min, P >0.05). There were statistically significant differences between the treatment and control groups in the increase rates of sperm concentration and TMS after medication (P 0.05).@*CONCLUSIONS@#Yijingfang is an effective drug for the treatment of asthenospermia, which can regulate the spermatogenesis, increase the percentage of PMS, and improve the total sperm motility of the patients.

Triple acupuncture at the Qugu acupoint as an adjunctive therapy for type-Ⅲ chronic prostatitis: Analysis of short- and long-term clinical effects / 中华男科学杂志

Objective@#To investigate the short- and long-term effects of triple acupuncture at the Qugu acupoint as an adjunctive therapy on type-Ⅲ chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS).@*METHODS@#We equally randomized 90 CP/CPPS patients into a control and a treatment group, both treated with Levofloxacin Mesylate Tablets (0.5 g, tid) + Terazosin Hydrochloride Capsules (2 mg qd) for 4 weeks, while the latter group by triple acupuncture at the Qugu acupoint as an adjunctive therapy twice a week at the same time. Then, we followed up all the patients for 4 weeks, recorded the cases, time and rate of recurrence, obtained the scores in National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), quality of life (QoL) and Zung Depression Scale (ZDS), and compared them between the two groups of patients.@*RESULTS@#Compared with the controls, the patients of the treatment group showed significantly decreased NIH-CPSI scores in pain (8.6 ± 2.12 vs 6.2 ± 2.25, P <0.05), micturition (5.8 ± 1.22 vs 3.1 ± 1.10, P <0.05), and QoL (6.0 ± 1.33 vs 3.4 ± 1.71, P <0.05) and ZDS score as well (43.9 ± 4.53 vs 33.6 ± 3.20, P <0.01). The recurrence rate was markedly lower while the recurrence time remarkably longer in the treatment than in the control group (15.56 vs 35.56% and ［20.0 ± 2.72］ vs ［12.5 ± 3.47］ d, P <0.05).@*CONCLUSIONS@#As an adjunctive therapy, triple acupuncture at the Qugu acupoint can evidently ameliorate the clinical symptoms, enhance the curative effect of antibacterials, reduce the recurrence rate, and prolong the recurrence time in the treatment of CP/CPPS.

Yijingfang increases the expression of CatSper1 in mice / 中华男科学杂志

<p><b>OBJECTIVE</b>To observe the effects of Yijingfang on CatSper1 in the mouse model of cyclophosphamide-induced oligoasthenospermia.</p><p><b>METHODS</b>Forty Kunming male mice were randomly divided into a control group (CG), a model group (MG), a small-dose Yijingfang group (SG), and a large-dose Yijingfang group (LG). The mice of CG were intraperitoneally injected with normal saline at 60 mg/kg once a day, while those of MG, SG and LG with cyclophosphamide, all for 5 days. During the next 34 days, the mice of SG and LG received intragastric administration of Yijingfang once a day, the former at a dose 2 times and the latter 5 times that of human routine usage, those of MG given the same volume of normal saline, and CG normally fed. At 35 days, we measured the sperm count, percentages of grades a + b and a + b + c sperm, and the expression of CatSper1 in the epididymal sperm of the mice.</p><p><b>RESULTS</b>The sperm counts of CG, MG, SG and LG were (5.20 +/- 1.34), (1.73 +/- 0.03), (2.08 +/- 0.01) and (3.31 +/- 0.56) x 10(6)/ml, respectively, significantly lower in MG than in CG (P < 0.05), but higher in LG than in MG (P < 0.05). The grade a + b sperm constituted (14.49 +/- 0.30), (6.64 +/- 1.88), (11.99 +/- 1.01) and (19.40 +/- 3.13)% in CG, MG, SG and LG, respectively, remarkably lower in MG than in CG (P < 0.05) but higher in LG than in MG (P < 0.05); the grade a + b + c sperm accounted for (68.39 +/- 15.13), (39.96 +/- 4.89), (62.28 +/- 4.43) and (73.61 +/- 5.05)%, respectively, obviously lower in MG than in CG (P < 0.05) but higher in LG than in MG (P < 0.05); the CatSper1 expressions were 0.76 +/- 0.05, 0.73 +/- 0.03, 0.75 +/- 0.12 and 0.85 +/- 0.04, respectively, markedly higher in LG than in MG (P < 0.05).</p><p><b>CONCLUSION</b>Intraperitoneal injection of cyclophosphamide decreases the sperm count, percentages of grades a + b and a + b + c sperm, and the expression of CatSper1 in mice, while large-dose Yijingfang can increase the above parameters, and hence contributes to the treatment of oligoasthenospermia.</p>
