METHODS: A total of 88 patients with acute exacerbation of chronic obstructive pulmonary disease admitted to the Department of Respiratory Medicine, Xuancheng People's Hospital of Anhui Province from December 2014 to December 2016 were randomly divided into the observation group and the control group, with 44 cases in each group. The control group was given routine clinical treatment, and the observation group was given Suhuang Zhike Capsule on the basis of the treatment method of the control group. After 7 days' treatment, the improvement of lung function indexes were observed and evaluated before and after treatment(forced expiratory volume in one second(FEV_1), forced expiratory volume occupancy in the 1^(st) second percentage of vital capacity(FEVl/FVC), peak expiatory flow(PEF)), blood gas analysis index(Arterial oxygen partial pressure(PaO_2) and arterial blood carbon dioxide partial pressure(PaCO_2), oxygenation index(OI)) and serum cytokine levels(procalcitonin(PCT) and C reactive protein(CRP). RESULTS: The total effective rate of the observation group was significantly higher than that of the control group(P < 0.05). The FEV_1, FEV_1/FVC and PEF in 2 groups were significantly increased after the treatment(P < 0.05), and the above lung function indexes in the observation group were significantly higher than the control group(P < 0.05). PaO_2 and OI were significantly increased after the treatment(P < 0.05), PaCO_2 was significantly decreased after the treatment(P < 0.05), and the improvement of above blood gas analysis indexes were significantly superior of the observation group than the control group(P < 0.05). The serum PCT and CRP levels in 2 groups were significantly decreased after the treatment(P < 0.05), and the improvement in the observation group were more significant than that in the control group(P < 0.05). CONCLUSION: Suhuang Zhike Capsule can inhibit serum inflammatory cytokine levels in patients with acute exacerbation of chronic obstructive pulmonary disease, improve blood gas analysis indicators, and improve lung functions.展开更多

In addition, the metabolic characteristics of LDH and ZKGC treatment were investigated with a liquid-chromatography with time-of-flight mass spectrometer (LC/Q-TOF-MS)-based metabolomics study. Nucleus pulpous tissues from rat models were collected and analyzed by metabolomics.[Results] By metabolism network analysis, lipid metabolism was up-regulated in LDH rat models and the treatment with ZKGC significantly reversed the abnormal up-regulated lipid metabolism. Meanwhile, the treatment of ZKGC also regulated the markers of neuron autophagy and inflammatory response in serum.[Conclusions] These results indicated that a complex mechanism, including abnormal lipid metabolism, associates with the progress of LDH, and multiple pathways might be involved in ZKGC s therapeutic effects on LDH.展开更多

The five analytes （liquiritin apioside, liquiritin, isoliquiritin apioside, liquirigenin and glycyrrhizic acid） were well separated with good linearity, precision, stability and repeatability. The recovery rates ranged from 95.69% to 100.80%. The content of the five compounds in 34 batches of commercial XEZKTJ products was determined using standardized GRR extract （SRE method） and individual chemical reference standards （CRS method）. Highly similar results were obtained from the two methods, demonstrating the feasibility of the proposed SRE method. Taken together, we proposed an efficient and low-cost way to perform multi-component quality control of XEZKTJ in this study.展开更多
