Objective To evaluate the efficacy of point application combined with catgut implantation at acupoint for lung-distention. Methods A total of 122 patients with lung-distension were randomized into a treatment group (62 patients) and a control group (60 patients). The patients in the control group received conventional treatment, and those in the treatment group were additionally treated with point application combined with catgut implantation at acupoint on the basis of the control group for 4 weeks. At 6 months follow-up, pulmonary function including the forced expiratory volume in first second (FEV1) and the percentage of FEV1 to forced vital capacity (FEV1/FVC), the total effective rate and acute exacerbation rate were compared in both groups. Results The total effective rate in the treatment group was significantly higher than that in the control group (98.4%vs. 85.0%;χ2=5.592, P<0.05). There were no significant difference in the acute exacerbation rate between the treatment group and the control group (8.1%vs. 20.0%;χ2=3.358, P>0.05).The FEV1 (treatment group: 71.58% ± 2.23% vs. 59.98% ± 2.19%, t=29.223, P<0.01; control group: 66.99% ± 2.25% vs. 61.03% ± 2.50%, t=13.726, P<0.01) and the FEV1/FVC (treatment group:68.99%± 1.33%vs. 50.77%± 1.45%, t=72.914, P<0.01; control group: 62.67% ± 1.47% vs. 51.89% ± 1.88%, t=34.989, P<0.01) after the treatment were significantly increased compared with before the treatment in both groups and such improvement in the treatment group was greater in the treatment group than that in the control group (FEV1: t=13.726, P<0.01;FEV1/FVC:t=34.989, P<0.01). Conclusion Point application combined with catgut implantation at acupoint can improve lung function and clinical effects in patients with lung-distention.
