ObjectiveTo explore the effect of Tanreqing injection combined with Ceftazide on the clinical efficacy， lung function， and laboratory inflammatory index of patients suffering from phlegm heat obstructing lung syndrome in acute exacerbation of chronic obstructive pulmonary disease （AECOPD）. MethodFrom June 2021 to June 2023， 76 patients diagnosed with phlegm heat obstructing lung syndrome in AECOPD were enrolled in the respiratory and critical medical department of Jieshou Hospital of Traditional Chinese Medicine. They were randomly divided into a control group and an observation group with 38 cases each. The control group used Ceftazidime intravenous drip and other conventional oxygen inhalation and antispasmodic treatment measures of western medicine. The observation group received Tanreqing injection intravenous drip based on the treatment of the control group， with a course of 10 days. The changes of laboratory indicators such as hs-CRP， calcitonin （PCT）， and interleukin-6 （IL-6） before and after treatment were analyzed， and the improvement of forced expiratory volume in the first second （FEV1）， forced vital capacity （FVC）， one second rate （FEV1/FVC）， assessment and improvement of the British Medical Research Society’s dyspnea index （mMRC）， self-evaluation test of chronic obstructive pulmonary disease patients （CAT）， and traditional Chinese medicine syndrome score was compared. In addition， the total effective rate between the two groups after treatment was compared. ResultAfter treatment， the hs-CRP， PCT， IL-6， FEV1， FVC， FEV1/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation of both groups improved （P<0.01）. After treatment， compared with the control group， the observation group showed more significant improvements in hs-CRP， PCT， IL-6， FEV1， FVC， FEV1/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation， and the difference was statistically significant （P<0.05，P<0.01）. The total clinical effective rate of the control group was 86.84% （33/38）， while that of the observation group was 94.74% （36/38）. The therapeutic effect of the observation group was better than that of the control group （χ2=8.471， P<0.05）. ConclusionTanreqing injection combined with Ceftazidime has obvious efficacy in the treatment of phlegm heat obstructing lung syndrome in AECOPD， which is better than the treatment of Ceftazidime antibiotics alone. It can reduce the risk of acute exacerbation， alleviate clinical symptoms， and delay the decline of lung function.

Mechanism of Tanreqing Injection in treatment of acute lung injury based on network pharmacology and molecular docking / 中国中药杂志

This study aimed to explore the mechanism of Tanreqing Injection in the treatment of acute lung injury(ALI) based on network pharmacology and molecular docking. The active components and action targets of Tanreqing Injection were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), PubChem, and SwissTargetPrediction databases, as well as available literature reports. The ALI-related targets were obtained from the GeneCards database and then mapped with Tanreqing Injection targets. Following the construction of "drug-component-potential target" network with Cytoscape 3.6.1, the potential targets were input into STRING to yield the protein-protein interaction(PPI) network, which was plotted using Cytoscape 3.6.1. Then the screened key targets were subjected to gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG) enrichment analysis based on DAVID database. The top three key targets RAC-alpha serine/threonine-protein kinase(AKT1), albumin(ALB) and interleukin-6(IL6) were docked to the top three key compounds by PyMOL and AutoDock vina. A total of 58 active components of Tanreqing Injection, 597 corresponding targets and 503 common targets shared by Tanreqing Injection and ALI were fi-gured out, with the key targets AKT1, ALB and IL6 involved. GO and KEGG enrichment analysis yielded 1 445 biological processes and 148 signaling pathways, respectively. Molecular docking verified a good binding ability of the top three key targets to the top three key compounds. The analysis based on network pharmacology and molecular docking uncovered that Tanreqing Injection directly or indirectly regulated the pulmonary capillary endothelial cells and alveolar epithelial cells via anti-inflammation, thus alleviating ALI.

Primary exploration of key influential factors recognization method of Tanreqing injection / 中国中药杂志

To recognize the key influential factors during the liquid preparation process of Tanreqing injection, the near infrared(NIR) spectra of the raw materials and the operating parameters of 24 batches of physical manufacturing were recorded as independent variables, and the total soluble solids contents and the light inspection acceptance rate of the final products were collected as dependent variables. The calibration models were developed using the partial least-square regression (PLSR) method, and the correlation coefficients between the independent variables and the dependent variables were calculated. For the quantitative models, the correlation coefficients for the calibration and inner cross validation of total soluble solids contents and the light inspection acceptance rate reached 0.911 9, 0.724 2 and 0.873 8, 0.795 9, respectively. Using the correlation coefficients diagrams, several key influence factors were preliminarily determined, and the physical significance were analyzed combined with production experience. This work demonstrated that NIR spectroscopy with PLSR algorithm could be used for the key influential factors recognization during the liquid preparation process of Tanreqing injection and can be popularized to solve similar problems..
