RÉSUMÉ
ObjectiveTo explore the effect of Qinggan Zishen prescription on metabolic disorders in obesity-related hypertension （OBH） patients and analyze the potential pharmacological mechanism based on network pharmacology. MethodA total of 85 eligible OBH patients who were treated in the outpatient or wards of Jiangsu Province Hospital of Chinese medicine from September 2018 to January 2020 were selected and randomized into the observation group （45 cases） and control group （40 cases）. All patients were treated with western medicine during a four-week introduction period， and then the observation group was treated with Qinggan Zishen prescription on the basis of western medicine. The study lasted 6 months， and indicators， such as triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， glycosylated hemoglobin （HbA1c）， fasting blood glucose （FBG）， fasting insulin （FINS）， waist circumference （W）， hip circumference （H） were detected and homeostasis model assessment of insulin resistance （HOMA-IR），body mass index （BMI）， waist-hip ratio （WHR） were calculated before and after intervention. At the same time， the regulation network of the Qinggan Zishen prescription was visualized and the protein-protein interaction （PPI） network was constructed. The core targets of the network were obtained for Gene Ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis. ResultAfter intervention for 6 months， the levels of W， H， WHR， FINS， and HOMA-IR in the observation group were reduced as compared with those in the control group （P<0.05， P<0.01）. According to network pharmacology， the main components of Qinggan Zishen prescription in treating OBH were luteolin， quercetin， and berberine and the key targets were amyloid precursor protein （APP）， vascular endothelial growth factor A （VEGFA）， and estrogen receptor 1 （ESR1）. Moreover， the key biological pathway was advanced glycation end product （AGE）/advanced glycation end product receptor （RAGE） signaling pathway. ConclusionQinggan Zishen prescription can improve the metabolic disorder of OBH patients through multiple components， multiple targets， and multiple pathways， which provides new mindset for follow-up studies.
