摘要
目的 评价苁蓉姜枣茶改善肾阳虚精血不足患者性功能与夜尿症状的临床疗效。方法 选取66例因肾阳虚精血不足导致男性性功能障碍的患者，随机分为对照组与干预组，每组33例。对照组采用五子衍宗丸治疗，干预组采用苁蓉姜枣茶治疗，疗程均为4周。通过比较治疗前后肾阳虚精血不足中医证候积分、临床总有效率及夜尿次数与体积等指标，评估两组的临床疗效。结果 治疗后，两组患者的肾阳虚精血不足中医证候总积分及各项症状评分均显著降低（P<0.05或P<0.01）。干预组的总有效率为90.9%，高于对照组的78.8%，但组间差异无统计学意义（P>0.05）。特别值得注意的是，干预组患者的夜间排尿次数和排尿体积均较治疗前显著下降（P<0.001）。结论 苁蓉姜枣茶能有效改善肾阳虚精血不足患者的性功能减退、腰膝酸软、畏寒肢冷及夜尿频多等一系列症状，尤其在减少夜尿次数和体积方面效果显著。

Abstract
Objective To evaluate the clinical efficacy of Congrong Jiang Zao Tea in improving sexual function and nocturia symptoms in patients with kidney yang deficiency and essence-blood insufficiency. Methods A total of 66 male patients with sexual dysfunction caused by kidney yang deficiency and essence-blood insufficiency were selected and randomly divided into a control group and an intervention group, with 33 cases in each group. The control group was treated with Wuzi Yanzong pills, while the intervention group was treated with Congrong Jiang Zao Tea. The course of treatment for both groups was 4 weeks. The clinical efficacy of the two groups was assessed by comparing the TCM syndrome scores for kidney yang deficiency and essence-blood insufficiency, the total clinical effective rate, and the number and volume of nocturia before and after treatment. Results After treatment, the total TCM syndrome scores and individual symptom scores for kidney yang deficiency and essence-blood insufficiency were significantly reduced in both groups (P<0.05 or P<0.01). The total effective rate was 90.9% in the intervention group, higher than the 78.8% in the control group, but the difference between the groups was not statistically significant (P>0.05). It is particularly noteworthy that the number of nocturnal voids and nocturnal urine volume in the intervention group were significantly decreased compared to those before treatment (P<0.001). Conclusion Congrong Jiang Zao Tea can effectively improve a series of symptoms in patients with kidney yang deficiency and essence-blood insufficiency, including sexual dysfunction, soreness and weakness of the waist and knees, aversion to cold, and cold limbs, and frequent nocturia. It is especially effective in reducing the number and volume of nocturia.
