Vascular Cognitive Impairment with Kidney Yang Deficiency Syndrome and DNA Methylation Essence / 中国实验方剂学杂志

ObjectiveTo investigate the distribution of vascular cognitive impairment （VCI） with kidney Yang deficiency syndrome and explore the biological nature of VCI with kidney Yang deficiency syndrome from the perspective of DNA methylation under the combination of disease and syndrome， so as to provide an epigenetic target for traditional Chinese medicine （TCM） treatment of this disease with this syndrome in the future. MethodCommunity residents in Beijing were screened out for cognitive impairment from September 2020 to November 2022 through the scale， and VCI patients were analyzed for the syndrome. VCI patients with kidney Yang deficiency syndrome and healthy people were enrolled in this study. Peripheral venous blood was collected and subjected to genome-wide DNA methylation detection by Illumina Human Methylation 850K BeadChip. Then， differentially methylated genes （DMGs） were screened out for bioinformatics analysis. ResultA total of 1 902 people were investigated in this study， and 201 of them had VCI， accounting for 10.57%， including 72.14% with kidney Yang deficiency syndrome. The methylation results showed that compared with the normal group， the VCI group had 386 differential methylation sites， and 136 DMGs were annotated. The Kyoto Encyclopedia of Gene and Genomes（KEGG） signaling pathway enrichment analysis showed that the DMGs between the two groups were mainly involved in mammalian target of rapamycin（mTOR） signaling pathway， Estrogen signaling pathway， cyclic adenosine monophosphate（cAMP） signaling pathway， etc. Protein-protein interaction （PPI） analysis showed that DMGs， such as epidermal growth factor receptor（EGFR）， epidermal growth factor （EGF）， and signal transducer and activator of transcription 3（STAT3）， played important roles in the network. ConclusionKidney Yang deficiency is the main syndrome in VCI patients. DMGs including EGFR， EGF， and STAT3 and the related pathways such as mTOR signaling pathway， Estrogen signaling pathway， and cAMP signaling pathway may play a vital role in the occurrence and development of VCI with kidney Yang deficiency syndrome.

Clinical Study on Jiangzhi Decoction in Regulating Lipometabolic Disorder with Stagnation of Phlegm and Blood-stasis / 中药新药与临床药理

Objective To investigate the therapeutic effect of Jiangzhi Decoction(JD) for the treatment of disordered lipid metabolism.Methods With Zhibituo Capsule as the control capsule,a random,paralleled and positive controlled clinical trial was carried out.A total of 64 patients were equally randomized into the treatment group and control group,and the treatment lasted 4 weeks.Results After administration,the level of total cholesterol(TC),triglyceride(TG),and arteriosclerosis index(AI) were reduced,the high density lipoprotein cholesterol(HDL-C) level was increased,and the sum of the decrease of electrocardiogram(ECG) ST segment was markedly improved in the treatment group,the difference being significant compared with those before treatment.In the treatment group,oppressive pain in the chest and hypochondrium,dizziness,limb numbness,poor appetite and headache were much relieved,and the relief of oppressive pain in the chest and hypochondrium,dizziness,and poor appetite was obvious as compared with the control group.Conclusion JD has good curative effect on disordered lipid metabolism with stagnation of phlegm and blood-stasis,in particular on relieving the clinical symptoms.
