System review of the Chinese medicine bushenhuoxue for treating benign prostatic hyperplasia / 中华男科学杂志

<p><b>OBJECTIVE</b>To make a system review of the effects of Bushenhuoxue (kidney-tonifying and blood-activating prescription), a category of compound Chinese medicines, on benign prostatic hyperplasia (BPH) and its side effects.</p><p><b>METHODS</b>All the research articles about Chinese medicines treating BPH from January 1978 to February 2003 were retrieved using the methods of international evidence-based medicine (EBM), and their qualities were evaluated based on JADAD standard and concealment of research allocation. Then the included articles went through META-analysis with Revman 4.2 software.</p><p><b>RESULTS</b>The efficacy of Bushenhuoxue on BPH was better than Qianliekang but not statistically different from finasteride. The combined use of Bushenhuoxue with surgery had no statistical difference from mere surgical treatment. Four articles reported the side effects of this compound Chinese medicine including upset and pain in the abdomen, nausea, diarrhea and dryness of the nose.</p><p><b>CONCLUSION</b>Massive, multi-center and randomized controlled clinical trials should be conducted to find out more effective methods for treating BPH with Chinese medicines based on the improvement of measurable symptom evaluation method and for evaluating their side effects.</p>

Experimental and clinical research on the effect of keyouling on condyloma acuminatum and adjustment of cellular immunity function / 中华男科学杂志

<p><b>OBJECTIVE</b>To discuss the mechanism of the traditional Chinese medicine Keyouling oral liquid in the treatment of condyloma acuminatum(CA) and the adjustment of cellular immunity function.</p><p><b>METHODS</b>The IL-18 and TNF-alpha levels of peripheral serum and wart tissue of patterned rats and CA patients exposed to Keyouling were determined by means of double-antibody sandwich ELISA, and the NK cellular activity of the spleen of the patterned rats and that of the peripheral blood of the CA patients exposed to Keyouling were determined by means of 3H-TdR isotype release.</p><p><b>RESULTS</b>The IL-18 and TNF-alpha levels, the NK cellular activity of the high-dosage group showed significant difference from those of the pattern group and low-dosage group in animal experiment(P < 0.05); the IL-18 and TNF-alpha levels of peripheral serum and wart tissues, and the NK cellular activity of the peripheral blood of the treatment group showed significant difference from those of the control group after treatment(P < 0.01, P < 0.05).</p><p><b>CONCLUSIONS</b>Keyouling oral liquid has significant positive adjusting effect, which can markedly ameliorate the cellular immunadeficiency of the patterned animals and reinforce the cellular immunocompetence of CA patients.</p>

Experimental research of PDE5 activity in corpora cavernosa of ganyu qizhi rat model / 中华男科学杂志

<p><b>OBJECTIVES</b>To study the PDE5 activity in corpora cavernosa of the Ganyu Qizhi model penis and the effect of the Chinese herbal medicine Shugan Liqi Huoxue (SLH) ointment on it.</p><p><b>METHODS</b>Non-injury stress stimulus method similar to human spirit stress was used to extablish the Ganyu Qizhi animal(rat) model, and the PDE5 activity in corpora cavernosa of the rat penis was measured by the method of immunohistochemistry and computer image analysis.</p><p><b>RESULTS</b>The PDE5 activity in corpora cavernosa of the high-dosage SLH group was significantly different from that of the model group (P < 0.01).</p><p><b>CONCLUSION</b>Ganyu Qizhi may increase the PDE5 activity in corpora cavernosa of the penis while SLH can reduce such activity.</p>

Effects of ZJG on the quality of sperm in male rat epididymis / 中华男科学杂志

<p><b>OBJECTIVE</b>To observe the effects of Chinese herbal composition Zengjing Granule (ZJG) on the quality of sperm in the epididymis of infertile rats, and to study its therapeutic mechanisms of improving sperm quality.</p><p><b>METHODS</b>A total of 40 GTW infertile rats were divided into 4 groups of 10 rats each, including an infertility group[GTW 2 mg/(ml.100 g)], a high-dosage group[ZJG 0.67 g/(ml.100 g) + GTW 2 mg/(ml.100 g)], a medium-dosage group[ZJG 0.33 g/(ml.100 g) + GTW 2 mg/(ml.100 g)], a low-dosage group[ZJG 0.17 g/(ml.100 g) + GTW 2 mg/(ml.100 g)], and a normal control group(1% CMC). This study consisted of a 3-week modeling period and a 3-week ZJG period. The changes of sperm quality, the thickness of the epididymal gland canal wall and sexual organ coefficient were detected after 3-week ZJG period.</p><p><b>RESULTS</b>Of the 3 ZJG groups, the sperm density was (59.6 +/- 3.72), (63.3 +/- 5.70) and (69.7 +/- 6.91) x 10(6)/ml, the sperm motility rates were (65.4 +/- 6.33)%, (69.3 +/- 10.96)% and (72.6 +/- 9.61)%, the sperm deformity rates were (52.3 +/- 7.47)%, (46.2 +/- 7.73)% and (33.2 +/- 7.97)% respectively. The ZJG groups showed significant difference from the infertility group (P < 0.05), whose sperm density, motility and deformity were (13.1 +/- 6.81) x 10(6)/ml, (7.6 +/- 5.87)%, and (77.2 +/- 8.75)% respectively. But there was no significant difference between ZJG groups and the normal control group (P > 0.05), whose sperm density, motility and deformity were (75.6 +/- 10.82) x 10(6)/ml, (83.00 +/- 8.02)%, and (8.80 +/- 3.49)% respectively. The thickness of the epididymal gland canal wall was (37.07 +/- 3.38), (37.16 +/- 6.69) and (43.42 +/- 10.23) nm in the three ZJG groups respectively, different from the infertility group[(28.65 +/- 6.96) nm] (P < 0.05) significantly, but not from the normal control group [(45.79 +/- 11.13) nm] (P > 0.05). The ZJG groups showed an increase in the organ coefficient of the epididymal gland canal wall. And these was obvious statistical difference compared with the infertility group (P < 0.05), but no statistical significance compared with the normal control group (P > 0.05).</p><p><b>CONCLUSIONS</b>ZJG can obviously improve the sperm quality of infertile rats. Its therapeutic mechanisms can be summed up as follows: restoring the thickness of epididymal gland wall, increasing the organ coefficient of testes and epididymis, and hence improving the spermatozoa maturing function of epididymis of infertile rats.</p>

Laboratory research of the influence of keyouling on the proliferation of human prepuce epidermis cells and condyloma acuminatum cells / 中华男科学杂志

<p><b>OBJECTIVE</b>To discuss the mechanism of the Chinese medicine Keyouling in the treatment of condyloma axuminatum (CA).</p><p><b>METHODS</b>Human prepuce epidermis cells and CA cells were primarily cultured and subcultured. We determined the proliferation of human prepuce epidermis cells and CA cells, and observed the influence of Keyouling with different concentrations on the proliferation of human prepuce epidermis cells and CA cells by means of MTT colourimetry assay.</p><p><b>RESULTS</b>The absorbance was directly proportional to the numbers of human prepuce epidermis cells (r = 0.9850, P < 0.001) and CA cells (r = 0.9892, P < 0.001). Keyouling had no effect on proliferation of the human prepuce epidermis cells, but it had significant inhibition on CA cells. The concentrations of Keyouling bore negative correlation with the proliferation percentage of CA cells(r = -0.4124, P < 0.01).</p><p><b>CONCLUSION</b>Keyouling can significantly restrain the growth and proliferation of CA cells but has no damaging effect on normal organic cuticle cells. It is suggested that Keyouling might have anti-HPV effect.</p>
