ABSTRACT
The efficacy on chronic obstructive pulmonary disease (COPD) at stable stage treated with different methods of acupuncture and moxibustion was evaluated using network Meta-analysis method. The articles of the randomized controlled trial (RCT) on stable COPD treated with acupuncture and moxibustion were searched electronically in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Web of Science and Cochrane library. The search was conducted from the inception of the databases to March 20th, 2022. Data analysis was performed using R4.1.1, Stata16.0 and RevMan5.3 softwares. A total of 48 RCTs were included, involving 15 kinds of acupuncture and moxibustion interventions and a sample size of 3 900 cases. The results of network Meta-analysis showed that: ① For the forced expiratory volume in one second predicted (FEV1%), both the governor vessel moxibustion combined with conventional treatment (G+C therapy) and the yang-supplementing moxibustion combined with conventional treatment (Y+C therapy) obtained the better effect than that of the conventional treatment (P<0.05), and the G+C therapy was more effective compared with the thread-embedding therapy combined with conventional treatment (E+C therapy) and warm needling (P<0.05). ② Concerning to COPD assessment test (CAT) score, the results indicated that the Y+C therapy, and the mild moxibustion combined with conventional treatment (M+C therapy) were more effective when compared with the conventional treatment (P<0.05), and the effect of the Y+C therapy was better than that of the E+C therapy (P<0.05). ③ Regarding six-minute walking distance (6MWD), the effect of acupuncture combined with conventional treatment (A+C therapy) was better than that of either the E+C therapy or the conventional treatment (P<0.05). The effect of the G+C therapy was optimal for improving FEV1%, the Y+C therapy obtained the best effect for improving CAT score, and A+C therapy was the most effective for improving 6MWD. Due to the limitation of the quality and quantity of included studies, this conclusion needs to be further verified through high-quality RCT.

OBJECTIVE@#To compare the clinical effect on chronic obstructive pulmonary disease (COPD) of lung deficiency at the stable stage treated with ginger-separated moxibustion and Chinese herbal medicine atomizaiton.@*METHODS@#A total of 90 patients with COPD of lung deficiency at the stable stage were randomized into an observation group (45 cases, 1 case dropped off) and a control group (45 cases, 2 cases dropped off). In the observation group, the ginger-separated moxibustion was applied to Dazhui (GV 14), Feishu (BL 13) and Gaohuangshu (BL 43), 2 moxa cones at each acupoint in each treatment. Additionally, the atomized inhalation with decoction and decoction was combined for 20 min, once every two days. The treatment for 10 times was taken as one course and 2 courses of treatment were required for 20 min. In the control group, ambroxol hydrochloride oral solution (10 mL) and compound methoxynamine capsules (2 capsules), were taken orally. Additionally, salbutamol aerosol was combined, 1 spray each time, three times a day, consecutively for 40 days. Before treatment and in 1-year followup after treatment, percentage of the forced expiratory volume in the first second predicated value (FEV1%) and its ratio to the forced vital capacity (FVC) (FEV1/FVC%) were determined in patients of the two groups. Before and after treatment, and in 3 months, 6 months and 1 year of followup after treatment, the score of COPD assessment test (CAT) and the score of traditional Chinese medicine (TCM) symptom were observed in the two groups separately. The clinical effect was assessed in 3-month followup after treatment and the frequency of the acute attack of COPD was followed up in 1 year after treatment in patients of the two groups.@*RESULTS@#In 1-year followup, FEV1% and FEV1/FVC% were increased in patients of the two groups (0.05). In 1-year followup, the acute recurrence rate of COPD was 20.5% (9/44) in the observation group, lower than 32.6% (14/43) in the control group (<0.05).@*CONCLUSION@#As compared with western medication, the combination of ginger-separated moxibustion and Chinese herbal medicine atomizaiton achieves the superior effects of improving the lung functions, reducing the clinical symptoms and decreasing the frequency of acute attack in patients with COPD of lung deficiency at the stable stage.
ABSTRACT
Objective: To investigate the effects of Wenshen-huatan method in patients with stable chronic obstructive pulmonary disease (COPD). Methods: Totally 146 patients with stable COPD admitted to the First Affiliated Hospital of Guangzhou Medical University from March 2016 to December 2017 were randomly divided into observation group and control group, with 73 in each group. The control group received routine treatment, while the observation group received Wenshen-huatan method based on the control group. The clinical efficacy and adverse reactions were compared between the two groups. Pulmonary function indexes, blood gas analysis indexes, modified medical British Research Council (mMRC) scores, 6-minute walking distance (6 WMD), serum nuclear factor-κB (NF-κB), soluble intercellular adhesion factor-1(sICAM-1), transforming growth factor-β1 (TGF-β1), and chemokine CC-motif ligand 18 (CCL-18) were measured before and after treatment. Results: The total effectiveness rate in the observation group was 93.15%, which was significantly higher than 79.45% in the control group (P<0.05). After treatment, the mMRC score and the TCM syndrome score were significantly lower in the observation group than those in the control group; the 6 MWD was significantly higher than that in the control group (P<0.05). The lung function index [forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1% pred, FEV1/FVC, peak expiratory flow rate (PEFR)], partial pressure of carbon dioxide (PaO2), and arterial oxygen pressure(SaO2) in the observation group were significantly higher than those in the control group; PaCO2 was significantly lower than the control group (P<0.05). The serum NF-κB, sICAM-1,TGF-β1, and CCL-18 in the two groups were significantly decreased, and the observation group had significantly lower levels than the control group (P<0.05). Conclusion: Wenshen-huatan method is effective for the treatment of stable COPD in that it can improve clinical symptoms, respiratory muscle fatigue and lung function, and can down-regulate the peripheral blood levels.
