Combined therapy of Compound Xuanju Capsules and traditional Chinese medicinal formula for infertility in male smokers / 中华男科学杂志

<p><b>Objective</b>To investigate the clinical effects of the combined therapy of Compound Xuanju Capsules (CXJC) and traditional Chinese medicinal formula on infertility in male smokers.</p><p><b>METHODS</b>A total of 176 male infertility patients were divided into a smoking and a non-smoking group and the former further divided into mild, moderate and heavy smokers according to the daily consumption of cigarettes and the length of smoking history. The patients were treated with CXJC combined with traditional Chinese medicinal formula for 3 four-week courses and the therapeutic results were evaluated by comparing the indicators of the traditional Chinese medicine (TCM) syndrome, routine semen parameters, sperm morphology, and sperm DNA fragmentation index (DFI) among different groups before and after treatment.</p><p><b>RESULTS</b>The baseline TCM syndrome scores were remarkably higher in the heavy smokers than in the non-smoking group (P < 0.05) but showed no statistically significant differences between the mild and moderate smokers (P > 0.05). The baseline percentage of sperm head defects and DFI were also markedly higher in the heavy and moderate smokers than in the non-smoking group (P < 0.05). Compared with the baseline, significant improvement was achieved after treatment in the TCM syndrome, routine semen parameters, sperm morphology and sperm DFI, especially in the heavy smokers in the percentages of grade a+b sperm (［17.12 ± 2.54］ vs ［30.15 ± 3.10］%, P < 0.05), morphologically normal sperm (［15.54 ± 1.98］ vs ［26.82 ± 3.52］%, P < 0.05), and head-defective sperm (［27.02 ± 2.14］ vs ［22.07 ± 1.52］%, P < 0.05).</p><p><b>CONCLUSIONS</b>Sperm quality is significantly decreased while the risk of infertility remarkably increased in moderate and heavy smokers. The combined therapy of CXJC and traditional Chinese medicinal formula can effectively improve semen quality, sperm morphology and sperm DFI in male smokers with infertility, though more evidence is to be collected from further studies.</p>

Effect of modified cangfu daotan decoction in improving endometrial receptivity in infertility patients with polycystic ovarian syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effect and potential mechanism of Modified Cangfu Daotan Decoction (MCDD) on endometrial receptivity in infertility patients with polycystic ovarian syndrome (PCOS).</p><p><b>METHODS</b>Totally 298 women having normal ovulation who underwent artificial insemination were recruited as the control group, and they received no drug therapy. Another 355 infertility patients with PCOS who received ovarian stimulation therapy were recruited as the treatment group. Then they were further assigned to the treatment group I (195 cases) and the treatment group II (160 cases) according to random digit table. Patients in the treatment group I received clomiphene (CC) + human menopause gonadotropin (HMG) +human chorionic gonadotropin (HCG), while those in the treatment group II received CC + HMG + HCG and additionally took modified MCDD. The therapeutic course for all was three menstrual cycles. The pregnancy ratio, the endometrial thickness, and spiral artery pulsatility index (PI), resistance index (RI), and homeostasis model assessment-insulin resistance (HOMA-IR) were measured. Furthermore, the uncoupling protein 2 (UCP2) level was tested by Western blot.</p><p><b>RESULTS</b>Compared with the control group, the endometrial thickness decreased and PI and RI increased in the treatment group I (all P < 0.05). Compared with the treatment group I , the endometrial thickness increased and PI and RI decreased in the treatment group II (all P < 0.05). Compared with before treatment, HOMA-IR levels were significantly decreased in the treatment group II after treatment (P < 0.05). Compared with the control group before treatment, the HOMA-IR level increased in the treatment group I and the treatment group II before treatment (P < 0.05). Compared with the control group after treatment, the HOMA-IR level increased in the treatment group I (P < 0.05). But there was no statistical difference in the post-treatment HOMA-IR level between the control group and the treatment group II (P < 0.05). Compared with the control group, the post-treatment UCP2 level was increased in the treatment group II (P < 0.05). After one year follow-up, the pregnancy rate was 16.1% (48/298) in the control group, 23.1% (37/160) in the treatment group I, and 33.8% (66/195) in the treatment group II. Compared with the control group, the pregnancy rate was significantly increased in the treatment group II (P < 0.05).</p><p><b>CONCLUSION</b>MCDD was found to be capable of increasing the pregnancy rate of infertility patients with PCOS, which might be associated with improving endometrial blood flow and insulin resistance, increasing the UCP2 expression, and finally improving the endometrial receptivity.</p>

Extract from Morindae officinalis against oxidative injury of function to human sperm membrane / 中国中药杂志

<p><b>OBJECTIVE</b>To study the intervention of Morindae officinalis extract in human sperm membrane, and to study the treatment of male infertility and asthenoospermia by M. officinalis.</p><p><b>METHOD</b>To select sperm with normal physiological function using the Percoll gradient centrifugation for the normal sperm model. Then separating the sperm suspension into the normal, model, and control group (Vitamin C group), and the large, medium and small dose of M. officinalis. The ROS was made from hypoxanthine-xanzine xanzine (HX-XO), and ROS, different concentrations (0.125, 0.25, 0.5 mg x mL(-1) of the extract were hatched with sperm in the oxygen environment, the sperm membrane Lipid peroxide injury were analyzed, and the function of sperm membrane were analyzed by sperm Hypoosmoticswelling (HOS) and compared with the controlled group.</p><p><b>RESULT</b>In the same conditions, all the small, medium and large extracts of M. officinalis (0.125, 0.25, 0.5 g x mL(-1)) improved SOD vitality of sperm suspension, reduced the content of MDA, intervened in the injury of sperm membrane by ROS to some extent and protected some function of sperm membrane.
