[Efficacy on chronic obstructive pulmonary disease at stable stage treated with cutting method and western...

To compare the difference in clinical efficacy on chronic obstructive pulmonary disease (COPD) at stable stage in the patients among the combined therapy of cutting method and western medication (combined therapy), simple cutting method and simple western medication.

One hundred and twenty cases of COPD were randomized into three groups, 40 cases in each one. In the cutting method group, for excessive phlegm pattern/syndrome, Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1) and Yuji (LU 10) were selected as the main acupoints, and Lieque (LU 7) and Pianli (LI 6) were as the supplementary acupoints. For the pattern/syndrome of failure to consolidate kidney primary, Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4) and Yuji (LU 10) were selected as main acupoints, and Jueyinshu (BL 14) and Zusanli (ST 36) were as the supplementary acupoint. Three acupoints were selected alternatively in each treatment and the cutting method was applied once every 10 days. Three treatments made one session. Two sessions of treatment were required. In the western medication group, salbutamol sulfate aerosol, one press (200 μg/press) was used each night, as well as salmeterol xinafoate and fluticasone propionate powder for inhalation, one inhalation each night. The treatment of 1 month made one session. Two sessions were required. In the combined therapy group, the cutting method and western medication were applied in combination. The results of clinical symptom score, lung function test, arterial blood gas analysis, degree of inflation as well as clinical efficacy were observed before and after treatment in each group.

Except the degree of lung inflation, the clinical symptom score, indices of lung function test, partial pressure of arterial blood gas (PaO2) and partial pressure of carbon dioxide (PaCO2) were all obviously improved after treatment as compared with those before treatment in each group (all P<0.05). They were apparently improved after treatment in the combined therapy group and the cutting method group as compared with those in the western medication group (all P<0.05). The total effective rate was 77.5% (31/40) in the combined therapy group and was 75.0% (30/40) in the cutting method group, both better than 60.0% (24/40) in the western medication group (both P<0.05).

The simple cutting method based on syndrome differentiation and the combined therapy with western medication achieve the superior efficacy on COPD at stable stage as compared with the simple western medication. The effect mechanism is possibly related to the improvement of bronchial airway function through constant acupoint stimulation.
