ABSTRACT
Objective To analyse the differential metabolites and related metabolic pathways in stable angina pectoris of coronary artery heart disease with spleen deficiency and phlegm turbidity syndrome by serum metabolomics.Methods This study observed 60 patients with stable angina pectoris of coronary artery heart disease with spleen deficiency and phlegm turbidity syndrome and 60 healthy volunteers in the same period.Liquid chromatography-mass spectrometry(LC-MS)was performed on the serum metabonomics.The differential metabolites were identified by multivariate statistical analysis of the original spectrogram and original data,and enrichment analysis of KEGG metabolic pathway was analyzed.Results A total of 60 patients in the group of stable angina pectoris of coronary artery heart disease with spleen deficiency and phlegm turbidity syndrome participated in the study,and a total of 60 healthy volunteers in the control group participated in the study.There was no statistical difference in general information and biochemical indicators between the two groups(P>0.05);Eighteen differential metabolites were found respectively,including phenylacetaldehyde,orthophosphate,guanosine,diethyl phosphate,2-dehydro-d-gluconate,guanine and 5-(2-hydroxyethyl)-4-methylthiazole down-regulated expression,taurocholate,2-propylglutaric acid,8-amino-7-oxononanoate,l-tyrosine,s-sulfo-l-cysteine,cyclohexanecarboxylic acid,porphobilinogen,(r)-acetoin,octanoylglucuronide,melatonin and solanine up-regulated expression,involving phenylalanine metabolism,thiamine metabolism,purine metabolism.Conclusion The differential metabolites reveal the metabolic essence of stable angina pectoris of coronary artery heart disease with spleen deficiency and phlegm turbidity syndrome from the micro level,and can provide clues for clinical early warning of patients with stable angina pectoris of coronary artery heart disease with spleen deficiency and phlegm turbidity syndromet.
ABSTRACT
Objective To explore the specific plasma exosomal protein expression in Coronary Heart Disease(CHD)with phlegm-turbidity syndrome(PTS),so as to provide biological reference for the diagnosis of CHD with PTS.Methods A total of 20 CHD patients with PTS and 20 healthy subjects at the same period were included.Plasma exosomes were extracted from all subjects using the qEV size exclusion method.First,10 CHD cases with PTS and 10 healthy subjects were randomly selected,and differentially expressed proteins between the two groups were screened using label free non-targeted protein quantification analysis.Then,MRM targeting protein labeling technique was applied to verify the differentially expressed proteins in the remaining subjects.Results Compared with healthy controls,214 differentially expressed plasma exosomal proteins(61 up-regulated and 153 down-regulated)were found in CHD patients with PTS,mainly related to cholesterol metabolism,complement and coagulation cascade,and immune effects.ANXA6,C4BPB,F8,CFB,APOE,C9,and CLU proteins were further validated by MRM targeting protein.Conclusion CHD patients with PTS had differences in plasma exosomal protein expression from healthy controls,and the differential proteins are mainly related to cholesterol metabolism,complement,and the coagulation cascade.
ABSTRACT
Objective To analyze the distribution of traditional Chinese medicine(TCM)syndromes in patients with acute pulmonary embolism(APE)and to summarize the medication rule,so as to supply evidence for the clinical diagnosis and treatment of APE. Methods A retrospective study was carried out in the APE inpatients admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine in recent 4 years. The general data, clinical manifestations at the attack of APE, TCM syndromes, treatment and prognosis of the included patients were input into the database for the analysis of TCM syndrome distribution and medication rule. Results A total of 139 cases of APE patients were included into the study. The main manifestations at admission were dominated by dyspnea and chest pain, pale or darkish red tongue, string pulse and deep pulse. TCM syndromes were divided into three types, phlegm turbidity syndrome, blood stasis syndrome and yang collapse syndrome. The blood stasis syndrome accounted for the largest proportion and then came the phlegm turbidity syndrome. In various age groups,the 3 syndrome types accounted the highest proportion in the age group of 51-70 years old, and accounted higher proportion in the age group over 71 years old. Blood stasis syndrome was frequently seen in the age group below 30 years old. Xuefu Zhuyu Decoction and Tao Hong Siwu Decoction were frequently used for the treatment of blood stasis syndrome, Gualou Xiebai Banxia Decoction and Wendan Decoction were often used for the phlegm turbidity syndrome, and Shenfu Injection was often used for yang collapse syndrome. Conclusion APE occurs in various clinical departments, and phlegm turbidity syndrome, blood stasis syndrome and yang collapse syndrome are the main syndrome patterns of APE. Blood stasis syndrome accounts the largest proportion in clinic. Therefore, Xuefu Zhuyu Decoction and Tao Hong Siwu Decoction, Gualou Xiebai Banxia Decoction and Wendan Decoction should be used as the indicated recipes for APE to activate blood and remove stasis, strengthen spleen and resolve phlegm.
ABSTRACT
This study was aimed to investigate potential biomarkers in different traditional Chinese medicine (TCM) syndromes of angina pectoris of coronary heart disease (CHD) by using metabolomic technology,and to explore the objective law of different TCM syndromes of CHD.Endogenous metabolites in serum and urine from the healthy group,and patients with DHD angina pectoris patients of the syndrome of Qi deficiency and blood stasis,as well as the syndrome of Qi deficiency,blood stasis and phlegm turbidity were detected by the liquid chromatography-mass spectrometry (LC-MS).Metabolic profiles were analyzed by the principal component analysis (PCA) and the orthogonal partial least squares discriminant analysis (OPLS-DA).The results showed that in PCA,the healthy group,Qi deficiency and blood stasis group,as well as the Qi deficiency,blood stasis and phlegm turbidity group can be obviously distinguished.Potential biomarkers in the Qi deficiency and blood stasis syndrome contained aspartyl methionine and cysteine sulfinic acid.Potential biomarkers in the Qi deficiency,blood stasis and phlegm turbidity syndrome contained hippuric acid,amino glucose,fructosamine and triglyceride.The objective performance of Qi deficiency syndrome was the absence of biotin,lysyl tyrosine,phosphatidylglycerol and glycocholic acid.It was concluded that through the new metabolomic technology,different endogenous metabolites in the syndrome of Qi deficiency and blood stasis,as well as the syndrome of Qi deficiency,blood stasis and phlegm turbidity of patients with DHD angina pectoris were detected.It provided ideas for the clinical practice of prevention,diagnosis and treatment of different TCM syndromes.
