Several parameters of ultrasonic nebulization extraction including the sample particle size, solvent volume, extraction time and ultrasonic power were studied and selected. As a result, 2.4 g of sample with particle size of 80 mesh was extracted with 15 mL of n-hexane for 20 min at an ultrasonic power of 35 W. The volatile components were analyzed by gas chromatography-mass spectrometry （GC-MS） under the optimal conditions and 57 compounds were identified. The precision, repeatability and stability of the proposed method were also studied. Compared with ultrasonic-assisted extraction（UAE） and hydrodistillation（HD） extraction, the proposed method is more efficient, faster and easier to be operated at room temperature with smaller sample and energy consumption. It is suggested that the ultrasonic nebulization extraction can be used as a novel alternative method for the extraction of volatile components from traditional Chinese patent medicine.展开更多

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
