ABSTRACT

Objective:To explore the medication law and core TCM prescriptions of Jia Yuejin in the treatment of coronary heart disease (CHD) complicated with depressive disorder (DD) by analyzing target-based network and mining clinical data.Methods:The targets of CHD complicated with DD were obtained by GeneCards, OMIM, TTD and other databases, and then the protein-protein interaction network of the two disease targets was constructed and then screened out the core targets. The Metascape platform was used to perform GO and KEGG pathway enrichment analysis on the intersection targets respectively to analyze the mechanism of action of CHD complicated with DD. Then TCMSP was used to query the active components acting on the targets and the Chinese materia medica containing these active components, and the data were imported into Cytoscape 3.9.0 to construct the core target-active component-Chinese materia medica network for network topology analysis. The outpatient clinical data of Jia Yuejin from January 1, 2015 to January 1, 2021 were collected, and data mining was conducted by using the Ancient and Modern Medical Case Cloud Platform (V2.3.5) to obtain his commonly used prescriptions. The results were fitted with the core TCM prescriptions obtained by target network analysis, and the drugs in the core prescriptions were analyzed.Results:Totally 1 501 intersection targets were obtained by protein interaction network analysis of CHD complicated with DD, which could be divided into 4 core target clusters, including inflammation cause, subclass tumor cause, subclass lipid metabolism factor, and fibrosis factor; a total of 480 active components were obtained by TCMSP, which belonged to 181 types of Chinese materia medica, including 8 core components: quercetin, kaempferol, luteolin, carotene, beta-carotene, acacetin, formononetin and ellagic acid. GO enrichment analysis yielded 61 results, mainly including positive regulation of protein phosphorylation, signal receptor agonist activity, side of membrane , etc.; KEGG pathway enrichment analysis yielded a total of 20 results, mainly including cancer pathways, lipid and atherosclerosis, JAK-STAT signaling pathway, etc. Clinical data mining included 120 cases and 148 prescriptions, including 135 types of Chinese materia medica; the properties were mainly mild, warm, slightly cold and cold; the tastes were mainly sweet, bitter and light, and the medicine mainly belongs to the lung, spleen, liver, heart, stomach, kidney and other meridians; drug association analysis, cluster analysis and complex network analysis were used to synthesize common prescriptions. The core TCM prescriptions obtained from common prescription and target network analysis were fitted: Pinelliae Rhizoma, Glycyrrhizae Radixet Rhizoma, Bupleuri Radix, Cyperi Rhizoma, Salviea Miltiorrhizae Radix et Rhizoma, Corydalis Rhizoma, Codonopsis Radix, Astragali Radix, Acori Tatarinowii Rhizoma. Conclusion:The medication law of Jia Yuejin in the treatment of CHD complicated with DD is in accordance with core TCM prescriptions. This study can provide guidance for clinical treatment and further research of CHD complicated with DD.

ABSTRACT

Objective To investigate the drug resistance of 1 031 Mycobacterium tuberculosis to rifampicin and isoniazide in the Center Hospital of Changsha from January 1 ,2013 to September 30 ,2014 .Methods A total of 1 031 strains with positive culture result and identified as strains of Mycobacterium tuberculosis were used absolute concentration method to do the conventional drug susceptibility ,and detected rifampicin and isoniazide resistance gene including rpoB ,katG and inhA gene locus mutation by chip technology ,the results of two methods were compared using card square test statistics .Results By gene chip method ,the sensitive strain of rifampicin was 896 ,the drug-resistant strains was 135 ,the sensitive strains of isoniazide was 901 strains ,130 drug-resistant strains .Compared with the absolute concentration method ,resistance chip detection results were consistent with rifampicin resistant strains 1 011 strains(including 894 drug-resistant strains ,and 117 sensitive strains) ,the coincidence rate was 98 .00% ,consistent with isoniazideresistant strains 1 005 strains(including 890 drug-resistant strains ,115 sensitive strains) ,the coincidence rate was 97 .48% .The most common spot of rifampin resistance related mutations of rpoB gene was 531TCG to TTG ,accounted for 51 .11% ,followed by 526CAC→TAC ,accounted for 10 .37% ,11 strains with 526TCG to TTG ,accounted for 8 .15% .Isoniazid re-sistance was caused by mutations in katG315AGC→ACC resistant strains ,accounted for 83 .85% ,inhA-15C→T mutations accoun-ted for only 12 .30% .Conclusion The results of gene chip method is highly consistent with that of absolute concentration method , could be a fast and effective method for screening rifampicin and isoniazide ,the resistant gene of Mycobacterium tuberculosis to rif-ampicin and isoniazide almost mutate in rpoB531 ,526 and katG315 in Changsha .
