Compoud Qingqin Liquids can obviously decrease the concentration of urine protein, blood uric acid, serum creatinine, blood urea nitrogen, and kidney weight index (P<0.05) of rats with uric acid nephropathy. Renal tubular epithelial cells atrophy and renal interstitial fibrosis of high-dose group of Chinese medicine were not evident. Conclusion Compoud Qingqin Liquids can protect the rats renal function against uric acid renal injury.

Objective:To evaluate the effectiveness of strengthening management in the bronchial asthma control among community patients.Methods:One hundred and eighteen community patients with bronchial asthma were recruited from January 2017 to January 2018. The patients were divided into community strengthening management group ( n=60) and control group ( n=58), the annual times of acute attack, time to first exacerbation and annual medical expenses were compared between the two groups. The proportion of inhaled corticosteroid (ICS) administration was documented; the Asthma Control Test (ACT), the Mini Asthma Quality of Life Questionnaire (MiniAQLQ), Leicester Cough Questionnaire (LCQ), Fractional exhaled nitric oxide(FeNO) and pulmonary function were evaluated in two groups. Results:The management group had greater improvements in the proportion of ICS administration [45(75.0%) vs.36(62.1%), χ 2=4.143], ACT [(20.7±3.9) vs.(18.1±4.1), t=3.213], LCQ [(13.5±5.3) vs.(10.8±3.0), t=2.603], FeNO [(29.8±12.8) vs. (37.1±11.1), t=2.018] than the control group after six months of management (all P<0.05). There were significantly greater improvements in proportion of ICS treating [50(83.3%) vs. 34(58.6%), χ 2=5.748], ACT [(22.1±2.8) vs. (19.5±2.3), t=2.241], LCQ [(16.5±4.2) vs. (11.6±3.2),=5.603], miniAQLQ [(83.2±11.1) vs.(68.1±13.3), t=3.186] and FeNO [(28.2±13.1) vs.(38.1±16.3), t=2.176] in management group than those in control group after one year of management (all P<0.05); but no differences were seen in FEV 1%, FVC%, FEV 1/FVC (all P>0.05) between two groups. The LCQ score [(16.5±4.2) vs. (13.5±5.3), t=3.186] and the MiniAQLQ score [(83.2±11.1) vs. (69.1±14.3), t=5.603] of the management group were significantly improved after 1 year of management than those after 6 months. There was significant improvement in time to first exacerbation [182(92, 284) vs. 92(58, 176), Z=4.384] and the annual exacerbation was significantly reduced [0(0, 1) vs. 2(1, 3), Z=-3.187], annual medical costs of management group were significantly lower than those of control group [(10 523.0±550.5)Yuan vs. (15 787.1±1 421.2)Yuan, t=2.653]. Conclusion:The strengthening management can effectively improve the control rate of bronchial asthma, reduce acute exacerbation, improve clinical symptoms and improve the quality of life in community patients with bronchial asthma.

ObjectiveTo study the mechanism of Mahuang Xixin Fuzitang （MXFT） against migraine. MethodTraditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， SiwssTargetPrediction and other databases were used to screen the active components and action targets of MXFT as well as migraine-related targets. The potential protein-protein interaction （PPI） network diagram was plotted for the intersection targets of MXFT and migraine using STRING 11.5. Metascape was used for Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis of potential intersection targets. The component-target-pathway network of MXFT was constructed by Cytoscape 3.7.1 to screen core targets with high degree value. Finally， the binding strength between core target and its mapping components was verified by molecular docking， and the core targets with desirable docking results were verified by animal experiments in vivo. Forty eight SD rats were selected， and except the blank group， the other rats were subcutaneously injected with nitroglycerin to prepare the migraine rat model. The modeled rats were randomly divided into model group， positive drug group and MXFT high-， medium- and low-dose groups. The positive drug group was given zolmitriptan tablets， and the MXFT high-， medium- and low-dose groups were given high， medium and low doses of MXFT， respectively. The changes of behavior and pain threshold of rats in each group were observed every other day after modeling. The levels of calcitonin gene-related peptide （CGRP）， extracellular signal-regulated kinase 2 （ERK2） and c-fos proto-oncogene （FOS） protein in plasma were detected by enzyme-linked immunosorbent assay （ELISA）. Immunohistochemical technique and Western blot were employed to determine the levels of extracellular signal-regulated kinase 1/2 （ERK1/2， also known as MAPK1/3） and protein kinase B 1 （Akt1）， protein kinase C α （PRKCA） in trigeminal nerve of SD rats. ResultThe network pharmacology showed that the core targets of MXFT in the treatment of migraine were MAPK1， MAPK3， Akt1， PRKCA， etc.， mainly involving neuroactive ligand-receptor interaction signaling pathway， calcium signaling pathway， MAPK signaling pathway， etc. The molecular docking demonstrated that MAPK1， MAPK3， Akt1， PRKCA， PRKCB and PRKCG had good binding ability with their mapping components. The animal experiments indicated that compared with the conditions in the blank group， the number of head scratching in the model group was increased （P<0.01）， and the pain threshold was decreased （P<0.01）. Compared with the conditions in the model group， the number of head scratching in each administration group was reduced （P<0.01）， and the pain threshold was increased （P<0.01）. In addition， the levels of CGRP， ERK2 and FOS proteins in plasma， and Akt1， ERK1/2 and PRKCA proteins in trigeminal ganglion of the model group were higher than those of the blank group （P<0.05， P<0.01）. The levels of CGRP， ERK2 and FOS proteins in plasma and Akt1， ERK1/2 and PRKCA proteins in trigeminal ganglion of each administration group were lower than those of the model group （P<0.05， P<0.01）. ConclusionMXFT had multi-component， multi-target and multi-pathway characteristics in the treatment of migraine， and the mechanism might be related to inhibiting vasodilation， reducing the release of inflammatory factors and inhibiting neuronal hyperactivity.
