目的：本研究是为了探讨子午流注纳子法针刺治疗脾虚湿蕴型溃疡性结肠炎的临床疗效。方法：选取70例脾虚湿蕴型溃疡性结肠炎患者，随机分为试验组和对照组，每组各35例。试验组采用子午流注纳子法针刺联合温针灸治疗，对照组采用常规西药治疗。比较两组患者的临床疗效、症状积分、肠镜评分。结果：试验组总有效率为91.4%，显著高于对照组(P Objective: This study aimed to investigate the clinical efficacy of Midnight-Midday Ebb-Flow (Ziwu Liuzhu) Na Zi Method Acupuncture in treating ulcerative colitis (UC) with spleen deficiency and dampness retention pattern. Methods: Seventy patients with UC of spleen deficiency and dampness retention type were randomly divided into an experimental group (35 cases) and a control group (35 cases). The experimental group received Midnight-Midday Ebb-Flow Na Zi Method Acupuncture combined with warm needling therapy, while the control group received conventional western medication. Clinical efficacy, symptom scores, and colonoscopy scores were compared between the two groups. Results: The total effective rate in the experimental group was 91.4%, significantly higher than that in the control group (P < 0.05). After treatment, both groups showed reductions in symptom scores and colonoscopy scores compared to baseline (P < 0.05), with greater improvements observed in the experimental group (P < 0.05). Conclusion: Midnight-Midday Ebb-Flow Na Zi Method Acupuncture combined with warm needling demonstrated significant efficacy in treating UC with spleen deficiency and dampness retention pattern, effectively alleviating clinical symptoms and intestinal mucosal lesions with good safety, making it worthy of clinical promotion.
