Objective To assess the clinical effect of Wuzi-Yanzong pill combined with compound Xuanju capsule for treatment of male infertility oligoasthenozoospermia. Methods 136 cases of infertility with less, weak spermatozoa patients who meet the inclusion criteria were divided into two groups using random number table, 68 cases in each group. The control group was treated with Wuzi-Yanzong Pills and Vitamin E orally, and the study group was treated with compound Xuanju capsules on the basis of the control group. Both groups were treated for 3 months. The changes of semen quality and male hormone were observed before and after treatment, and the clinical curative effect was evaluated. Results The total effective rate of the study group was 89.7% (61/68), the control group was 73.5% (50/68), there was significant difference between two groups (χ2=5.930, P=0.015). After treatment, in study group, the sperm of a grade and b grade were (68.5% ± 15.5 % vs. 52.5% ± 15.6 %, t=2.607), the sperm of a grade was (35.3% ± 15.3% vs. 26.5% ± 13.4%, t=2.688), sperm motility rate was (73.3% ± 22.5% vs. 56.8% ± 20.5%, t=2.780), sperm density was [(28.7 ± 15.5)×107/ml vs. (20.5 ± 13.2)×107/ml, t=2.612], and the sperm volume was (2.9 ± 1.7 ml vs. 2.2 ± 1.3 ml, t=2.667), higher than those of the control group (P<0.05 or P<0.01). The level of testosterone in study group (816.5 ± 135.6 ng/dl vs. 768.5 ± 118.5 ng/dl, t=2.728). Conclusions Wuzi-Yanzong pills combined with compound Xuanju capsule can effectively improve the quality of spermatozoa for patients with oligospermia, and improve the clinical efficacy.

BACKGROUND: Hypertension is associated with stroke-related mortality. However, the long-term association of blood pressure (BP) and the risk of stroke-related mortality and the influence path of BP on stroke-related death remain unknown. The current study aimed to estimate the long-term causal associations between BP and stroke-related mortality and the potential mediating and moderated mediating model of the associations. METHODS: This is a 45-year follow-up cohort study and a total of 1696 subjects were enrolled in 1976 and 1081 participants died by the latest follow-up in 2020. COX proportional hazard model was used to explore the associations of stroke-related death with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) categories and BP changes from 1976 to 1994. The mediating and moderated mediating effects were performed to detect the possible influencing path from BP to stroke-related deaths. E value was calculated in the sensitivity analysis. RESULTS: Among 1696 participants, the average age was 44.38 ± 6.10 years, and 1124 were men (66.3%). After a 45-year follow-up, a total of 201 (11.9%) stroke-related deaths occurred. After the adjustment, the COX proportional hazard model showed that among the participants with SBP ≥ 160 mmHg or DBP ≥ 100 mmHg in 1976, the risk of stroke-related death increased by 217.5% (hazard ratio [HR] = 3.175, 95% confidence interval [CI]: 2.297-4.388), and the adjusted HRs were higher in male participants. Among the participants with hypertension in 1976 and 1994, the risk of stroke-related death increased by 110.4% (HR = 2.104, 95% CI: 1.632-2.713), and the adjusted HRs of the BP changes were higher in male participants. Body mass index (BMI) significantly mediated the association of SBP and stroke-related deaths and this mediating effect was moderated by gender. CONCLUSIONS In a 45-year follow-up, high BP and persistent hypertension are associated with stroke-related death, and these associations were even more pronounced in male participants. The paths of association are mediated by BMI and moderated by gender.
