Methods： Search double-blind randomised clinical trials（RCT） about the use of TCM aerosol inhalation in patient with acute exacerbation of chronic bronchitis via database including Chinese biomedicine literature database, Wanfang Data, CNKI, Pubmed, EMBASE and CochraneLibrary from the beginning to October 2016. Quality evaluation, data extraction and data analysis of these RCT wascarried out with reference to the Cochrane systematic review. Results： 16 studies with 738 patients in TCM aerosolinhalation group and 675 in control group were included. The results of meta-analysis showed, （1） TCM aerosolinhalation group could improve the total cure rate. （2） TCM aerosol inhalation could increase the expression of IL-2while decrease the expression of IL-8 and MDA in sputum and blood. （3） TCM aerosol inhalation could improvethe symptoms of cough, cough with sputum, cough with dyspnea and lung wet rales. It also improve the symptomsof cough, expectorate and lung wet rales. （4） Shorten the time of cough and lung rale. （5） The adverse reactionswere light only with 1 occurrence of nausea and vomiting. Conclusions： The use of TCM aerosol inhalation in thetreatment of acute exacerbation of chronic bronchitis was effective. However, the inclusion researches quality werenot very high, which only provided limited evidence for clinical application. Higher-quality randomized controlledtrials were needed for further study.展开更多

This study was designed to observe the effects of early massive bronchoalveolar lavage fluid (BALF) on the healthy lungs in rats. Methods: Mongrel dogs were inflicted with severe smoke inhalation injury. The injured lungs were lavaged with large amount of normal saline in the first hour after injury and the BALF was collected. The BALF was injected into the healthy lungs of 30 rats (group C) in the dosage of 5 ml/kg. The functions and pathological changes of the lungs were observed 24 h after perfusion with the BALF. The data were compared with those of 23 rats (group B) whose lungs were perfused with the BALF collected from normal dogs and those of 21 rats (group A) whose lungs were perfused with normal saline. Results: The mortality rate 24 h after lung perfusion was higher in group C than in groups A and B. The survivors of group C exhibited fluctuation of respiratory rate (RR), remarkable decrease of PaO 2, significantly higher content of lung water, decrease of total static pulmonary compliance and pulmonary expansion index, and increasse of inflammatory cytokines in the tissues of lungs. Only slight mechanic obstructive effect on the airway was observed in rats of group A and B. The pathological changes of the lungs of the rats in group C were similar to those of the dogs with actual smoke inhalation injury. Conclusion: Our findings indicate that the BALF collected from dogs with acute severe smoke inhalation injury in the early stage after injury injured the normal lungs of rats with the bioactive substances in the BALF. These findings show us that it is a valuable therapeutic procedure to apply massive bronchoalveolar fluid lavage in the early stage after inhalation injury.展开更多

Methods Chronic bronchitis sequential rat model was established by passively inhaling smoke mixture. Experiments were performed in 30 young male Sprague-Dawley rats, which comprised 5 groups in random, i.e.,4 chronic bronchitis model groups and 1 control group. After stained with hematoxylin and eosin, the specimens were studied by semi-quantitative method to evaluate the morphologic changes in various stages. Meanwhile, the inflammatory cells of the BALF and the activity of myeloperoxidase (MPO) of lung tissue were analysed. Results During the process of the chronic bronchitis, the pathologic score was increasing as time went on, and the typical morphologic changes of chronic bronchitis emerged in the group 7 weeks. The total number of inflammatory cells in BALF was increasing as time went on, correlated with the pathologic scores (P <0.01). And the percentage of lymphocyte increased as well as positively correlated with pathologic scores (P < 0. 05) , whereas that of macrophage decreased and negatively correlated with pathologic scores (P <0. 05). The MPO lever of lung tissue was correlated with the pathologic scores (P < 0. 01). But the percentage of the neutrophil in the BALF was just in a high level during the first week, then it maintained relatively lower. Conclusion Smoke-induced chronic bronchitis is a slowly progressive inflammation process. The model we established is convenient and simple for the longitudinal study on the inflammatory process of chronic bronchitis and the therapy in the early stage. The semi-quantitative evaluation for the pathological change is with much more value. During the inflammatory sequential process of early stage of chronic bronchitis, the cellular characteristics are similar to that of the common chronic inflammation.展开更多
