RESUMO
<p><b>Objective</b>To investigate the effects of Qiangjing Tablets (QJT) on sperm quality and the MAPK signaling pathway in the SD rat model of asthenospermia (AS).</p><p><b>METHODS</b>A total of 100 male SD rats were randomly divided into five groups of equal number, blank control, AS model control, high-dose QJT, medium-dose QJT, and low-dose QJT. All the rats were intragastrically administered ORN at 200 mg/kg/d for establishment of the AS model except those in the blank control group, which were given 1% CMC sodium solution at 1 ml/100 g by gavage. Meanwhile the animals of the high-, medium-, and low-dose QJT groups were gavaged with QJT at 6700, 3300 and 1700 mg/kg/d, respectively, qd 6 days a week for 20 days. Then the testis issue and the apoptosis of the testicular cells were observed under the electron microscope, the expression of vimentin in the testis was determined with the immunohistochemical SP method, that of ERK1/2 detected by Western blot, and the concentration of TGF-β1 in the semen measured by ELISA.</p><p><b>RESULTS</b>The AS model controls showed round nuclei of spermatocytes, homogeneously distributed chromatins, broken or lost mitochondria, and expanded rough endoplasmic reticulum in the testis tissue. In comparison, the rats of the high-, medium-, and low-dose QJT groups exhibited round nuclei of spermatocytes, homogeneously distributed chromatins, and well-structured mitochondria, rough endoplasmic reticulum and ribosome, which were all similar those of the blank controls. Compared with the blank controls, the AS model rats manifested significantly increased expressions of ERK1/2 (1.00 ± 0.00 vs 1.26 ± 0.10, P<0.01) and vimentin (0.16 ± 0.01 vs 0.17 ± 0.01, P<0.01) and apoptosis rate of cells in the testis tissue ([9.20 ± 3.07] vs [42.20 ± 9.17] %, P<0.01), but decreased level of TGF-β1 in the semen ([627.67 ± 26.07] vs [566.73 ± 68.44] ng/ml, P<0.05). In comparison with the model controls, the rats of the high- and medium- -dose QJT groups presented remarkably down-regulated expressions of ERK1/2 (1.26 ± 0.10 vs 1.14 ± 0.08, P<0.01; 1.26 ± 0.10 vs 1.18 ± 0.05, P<0.05) and vimentin (0.17 ± 0.01 vs 0.16 ± 0.01, P<0.01; 0.17 ± 0.01 vs 0.17 ± 0.09, P<0.05) and decreased rate of cell apoptosis ([42.20 ± 9.17] vs [21.60 ± 5.94] %, P<0.01; [42.20 ± 9.17] vs [33.95 ± 6.39] %, P<0.05). The concentration of TGF-β1 in the semen was markedly lower in the high-dose QJT than in the AS model control group ([621.78 ± 30.80] vs [566.73 ± 68.44] ng/ml, P < 0.05).</p><p><b>CONCLUSIONS</b>Qiangjing Tablets could improve semen quality in asthenospermia rats by acting against oxidative stress.</p>

<p><b>OBJECTIVE</b>To observe the effects of Qiangjing Tablets (QJT) on the semen quality and Fas/FasL signaling pathway in male SD rats with infertility.</p><p><b>METHODS</b>Models of infertility were made in 50 male SD rats by intragastric administration of Tripterygium (GTW) for 3 weeks, and another 20 rats were taken as blank controls. Then 40 successfully established rat models were randomly divided into four groups, model control, low-dose QJT, medium-dose QJT, and high-dose QJT, the latter three groups treated intragastrically with QJT at 58 mg, 105 mg, and 233 mg per kg of the body weight per day, respectively. After 4 weeks of medication, the rats were killed for examination of semen quality and determination of the expression of the apoptosis factor FasL in the testis tissue.</p><p><b>RESULTS</b>Compared with the blank controls, the model rats showed significant decreases in sperm concentration ([71.99 ± 9.72] vs [10.94 ± 3.58] x 10⁶/ml, P < 0.01), motility ([48.95 ± 4.10] vs [9.31 ± 5.79]%, P < 0.01), and viability ( [82.06 ± 6.16] vs [24.03 ± 6.93]%, P < 0.01). In comparison with the model controls, the rats in the QJT groups exhibited remarkably increased sperm concentration, motility, and viability, more significantly in the high-dose group ([59.66 ± 4.53] x 10⁶/ml, [35.45 ± 5.21] %, and [61.97 ± 9.75]%) and medium-dose group ([40.89 ± 4.90] x 10⁶/ml, [24.41 ± 4.79]%, and [60.06 ± 10.62]%) (P < 0.05 or P < 0.01). The expression of FasL was markedly reduced in the low-, medium-, and high-dose QJT groups (0.5215 ± 0.0189, 0.5371 ± 0.0364, and 0.4556 ± 0.0215) as compared with that of the model controls (0.5989 ± 0.0448 ) (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>By upregulating the Fas/FasL signaling pathway, Tripterygium glycosides may induce the apoptosis of spermatogenic cells and reduce sperm concentration, motility and viability, resulting in infertility. The Chinese medicine Qiangjing Tablets can improve the reproductive function of male rats by decreasing the expression of the apoptosis factor FasL in the testis.</p>

<p><b>OBJECTIVE</b>To assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.</p><p><b>METHODS</b>This was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.</p><p><b>RESULTS</b>After treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.</p><p><b>CONCLUSION</b>The combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.</p>

<p><b>OBJECTIVE</b>To evaluate the clinical effects of Yuleshu oral mixture combined with conventional therapy on chronic prostatitis.</p><p><b>METHODS</b>Eighty-eight patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) were equally randomized to a control and an experimental group to receive conventional therapy (oral antibiotics, alpha blockers, proprietary Chinese medicine for activating blood circulation and massage of the prostate) and conventional therapy combined with Yuleshu oral mixture respectively. Before and after treatment, the severity of symptoms and sexual function of the patients were evaluated using NIH-CPSI and IIEF-5, their anxiety, depression and other emotional problems assessed with Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Scale (HAMA), and the results subjected to statistical analysis.</p><p><b>RESULTS</b>Both the experimental and control groups showed significant improvement in prostatitis symptoms and sexual function after treatment as compared with the baseline (P < 0.01), even more significant in the former than in the latter group, especially in pain symptoms (7.89 +/- 2.82 vs 10.41 +/- 2.55, P < 0.01). Before and after treatment, the HAMA and HAMD score had no significant difference in the control, but there was significant difference in the experimental group. The experimental group exhibited remarkably higher scores after than before treatment on HAMA (24.30 +/- 5.07 vs 13.80 +/- 3.62, P < 0.01) and HAMD (23.81 +/- 5.01 vs 16.23 +/- 5.93, P < 0.01), but not the control group (P > 0.05).</p><p><b>CONCLUSION</b>Yuleshu oral mixture can effectively relieve anxiety, depression and other psychological problems in CP/CPPS patients, and improve their clinical symptoms as well. Therefore, it is an effective drug for chronic prostatitis.</p>

<p><b>OBJECTIVE</b>To investigate the correlation of International Prostate Symptom Score (IPSS) with the levels of interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in the prostate tissue and expressed prostatic secretion (EPS) in patients with benign prostatic hyperplasia (BPH) complicated by prostatitis.</p><p><b>METHODS</b>We divided 80 BPH patients to be treated by transurethral resection of the prostate (TURP) into a simple BPH group (n = 30) and a BPH with prostatitis group (n = 50) based on the pathologic features. We statistically analyzed IPSS and the levels of IL-8 and COX-2 in EPS before surgery and the IL-8 and COX-2 levels in the prostate tissue after surgery.</p><p><b>RESULTS</b>IPSS was positively correlated with the IL-8 and COX-2 levels in the prostate tissue and EPS of the BPH patients, moderately in the simple hyperplasia group (r > 0.5) and highly in the other (r > 0.8). The levels of IL-8 and COX-2 in the prostate tissue and EPS were significantly higher in the BPH with prostatitis group than in the simple BPH group (P < 0.05).</p><p><b>CONCLUSION</b>The levels of IL-8 and COX-2 in EPS indirectly reflect those in the prostate tissue. IPSS and the levels of IL-8 and COX-2 in EPS can help determine whether BPH is complicated by histological prostatic inflammation.</p>

<p><b>OBJECTIVE</b>To assess the association between leptin gene promoter methylation and serum leptin concentrations in patients with impaired glucose regulation (IGR) and type 2 diabetes mellitus (T2DM).</p><p><b>METHODS</b>Methylation status of leptin gene promoter was determined with methylation-specific polymerase chain reaction. Serum leptin concentrations were determined using enzyme-linked immunosorbent assay.</p><p><b>RESULTS</b>Among three groups of individuals with different levels of glucose, the methylation rates of leptin gene in IGR and T2DM groups were 43.6 % and 31.5 %, respectively, which were significantly lower than that of healthy subjects (59.2%; Chi-square=22.499 and 5.109, respectively, P<0.05). A lower methylation rate was also observed in T2DM group compared with IGR group (Chi-square=3.962, P<0.05). Leptin levels in both T2DM and IGR groups were elevated compared with normoglycemic subjects, but only T2DM group was significantly higher (q=6.81, P<0.01). Linear regression analysis indicated that serum leptin concentrations has increased along with declining of DNA methylation rate (r=-0.95, P<0.01).</p><p><b>CONCLUSION</b>Lower levels of leptin gene promoter DNA methylation and serum leptin concentrations are associated with the development of diabetes. Measurement of the methylation status of leptin gene promoter and expression can facilitate early intervention of the disease.</p>

<p><b>OBJECTIVE</b>To explore the clinical characteristics of benign prostatic hyperplasia (BPH) complicated by chronic prostatitis (CP).</p><p><b>METHODS</b>A total of 120 cases of BPH pathologically confirmed after transurethral resection of the prostate (TURP) were assigned to a BPH group (n=75) and a BPH + CP group (n=45) according to whether they were complicated by CP. The total prostatic volume (TPV) and PSA density (PSAD) were calculated and statistically analyzed based on the results of transrectal ultrasonography and f-PSA, t-PSA and f-PSA/t-PSA tests before surgery.</p><p><b>RESULTS</b>The BPH group showed a significantly upward tendency in f-PSA and t-PSA (P < 0.05) with the increase of age or prostate volume, but not significantly in PSAD and f-PSA/t-PSA (P > 0.05). In comparison, the BPH + CP group exhibited remarkable increases in f-PSA, t-PSA and PSAD (P < 0.05) but not in fPSA/t-PSA (P > 0.05). ROC curve analyses of various indexes showed the area under the curve to be 0.644, 0.628 and 0.624 for f-PSA, t-PSA and PSAD, respectively, all between 0.5 and 0.7.</p><p><b>CONCLUSION</b>BPH is frequently associated with CP. Clinically, high f-PSA, t-PSA and PSAD are important but not sure indicators of BPH complicated by CP.</p>
