Outcome measures were the NLR and the scores from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30). The NLR and the EORTC QLQ-C30 were assessed at baseline and at the end of 6 weeks.RESULTS: Five participants dropped out, leaving afinal total of 65 participants who completed the trial. Groups A and B had a similar mean NLR at baseline. After the treatment course, the NLR in group A was significantly lower than that in group B(P <0.001). Compared with group B, the EORTC QLQ-C30 scores in group A were significantly greater in terms of global health status or quality of life(P < 0.001) and function(P < 0.05), and significantly lower in terms of symptoms(P < 0.05).CONCLUSION: The present study suggests that performing scar-producing moxibustion by heat-stimulating the acupoints Zusanli(ST 36) and Feishu(BL13) effectively decreases the NLR and improves the quality of life in patients with NSCLC.展开更多

Using micro-dialysis technology, preprocessed skin probes were implanted into the rats at Feishu(BL 13), Dazhui(GV 14), and a nonacupoint site. Asthma gel was then placed on the skin at Feishu(BL 13), Dazhui(GV14) acupoints, and the nonacupoint for all groups.Dialysate was collected every 30 min for 12 h. The normalized concentration of sinapine thiocyanate in the skin was determined by high-performance liquid chromatography.RESULTS: The rat in vivo transdermal experiment demonstrated that the quantity-time equation showed a good linear correlation with zero-order kinetics(r > 0.99). The transdermal behavior was in accordance with the first-order rate open model in which the transdermal penetration rates and the accumulative amounts of sinapine thiocyanate in the skin at the acupoint sites were greater than those through the skin of the nonacupoint site. The systemic maximum concentration and the area under the curve of sinapine thiocyanate in the acupoint groups were significantly greater than in the nonacupoint group. A lag time was observed in both acupoint groups, but not in the nonacupoint group.CONCLUSION: Stimulating the acupoints promotes the percutaneous absorption of sinapine thiocyanate and also controls its release, reducing concentration fluctuations in the blood.展开更多

Acupuncture can improve lung function in patients with COPD, but the underlying mechanisms are not well understood. Orexins （OXs）, which are found in peripheral plasma, are neuropeptides that regulate respiration and their levels are related to COPD. Therefore, we hypothesized that acupuncture might alter OXs, reduce lung inflammation and improve lung function in COPD. METHODS： COPD was induced in rats by exposure to cigarette smoke for 8 weeks and injecting with lipopolysaccharide twice. Electroacupuncture （EA） was performed at Feishu （BL13） and Zusanli （ST36） for 30 min/d for 2 weeks. Rat lung function and morphology were assessed after EA. The levels of tumor necrosis factor-α （TNF-a） and intedeukin-1β （IL-16） in bronchoalveolar lavage fluid （BALF） and orexin A and B levels in the lung tissue were detected by enzyme-linked immunosorbent assay. OX receptor mRNA levels and immunopositive cells were assessed with real-time polymerase chain reaction and immunohistochemical methods, respectively. The relationships among lung function, cell factors, and OX levels were analyzed by Pearson correlation analyses. RESULTS： Compared with the control group, lung function was significantly decreased in the rats with COPD （P〈0.05）. There were obvious increases in TNF-α and IL-1β levels in BALF （P〈0.05 and P〈0.01, respectively）, orexin A level in lung tissue （P〈0.01; but not orexin B） and mRNA expressions of OX 1 type receptor （OXR1） and OX 2 type receptor （OXR2） in lung tissue （P〈0.05 and P〈0.01, respectively）; the integrative optical densities （IODs） of both receptors were greater in the COPD group （P〈0.05）. For rats with COPD subjected to EA, lung function was improved （P〈0.05）. There were notable decreases in TNF-a and IL-1β levels （P〈0.05 and 〈0.01, respectively） in BALF. Orexin A, but not orexin B, levels in lung tissue also decreased （P〈0.01）, as did mRNA expression of OXlR and OX2R in lung tissue （P〈0.05 and P〈0.01, respectively）. Receptor IODs were also reduced after EA treatment （P〈0.05）. Furthermore, orexin A levels and ratio of forced expiratory volume in 0.3 s to forced vital capacity were strongly negatively correlated （P〈0.01）, and orexin A was positively correlated with TNF-α and IL-1β （P〈0.001 and P〈0.05, respectively）.CONCLUSION： EA at Zusanli and Feishu improved lung function of rats with COPD and had an anti-inflammatory effect, which may be related to down-regulation of OXA and its receptors.展开更多
