RESUMEN
Objective:To obtain the regulatory relationship between genes by screening the differentially expressed long non-coding ribonucleic acid(lncRNA), microRNA(miRNA) and messenger RNA(mRNA) in serum of patients with Yin and Yang syndromes of acute ischemic stroke, and to discuss the material basis and biological mechanism of formation of Yin and Yang syndromes of acute ischemic stroke from the transcriptome level. Method:The microarray chips were adopted to detect expression of lncRNA, mRNA and miRNA in serum of ischemic stroke patients with Yin and Yang syndromes and non-stroke subjects(10 cases each). Differential expression profiles related to Yin and Yang syndromes were selected by conjoint analysis. Further, the obtained differential genes were subjected to antisense lncRNA and mRNA co-expression analysis, gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG) functional pathway analysis, and the intergenic regulatory relationship was obtained to predict the target genes of lncRNA. Partial differential genes in 40 patients(10 with Yang syndrome and 30 with Yin syndrome) were verified by real-time fluorescence quantitative polymerase chain reaction(Real-time PCR). Result:The expression of 227 lncRNA, 54 mRNA and 4 miRNA were closely related to Yang syndrome, 394 lncRNA and 206 mRNA were closely related to Yin syndrome. Antisense lncRNA RP11-647P12.1 and RP11-677M14.2 may regulate the expression of neuron-derived neurotrophic factor(NDNF) and neurogranin(NRGN) by up-regulating the expression level in Yang syndrome. The differential expression of mRNA between Yin syndrome and Yang syndrome was mainly related to neurotransmitter receptor activity regulation, endocrine hormone regulation, inflammatory response, renin-angiotensin system and other pathways. Conclusion:There are differences in the expression profiles of lncRNA, miRNA and mRNA between Yin syndrome and Yang syndrome in acute ischemic stroke, which may be regulated by multiple pathways, such as blood pressure regulation, adrenergic receptor regulation, renin-angiotensin system and γ-aminobutyric acid(GABA). The transcriptome characteristics provide scientific basis for studying the biological basis of Yin syndrome and Yang syndrome in acute ischemic stroke.
RESUMEN
OBJECTIVE@#To identify the differentially expressed microRNAs (miRNAs) profiles of yang and yin syndromes in patients with acute ischemic stroke, and to provide the molecular basis of the classification of these two syndrome types in acute ischemic stroke patients.@*METHODS@#A microarray assay was performed to assess the expression pattern of miRNAs in the lymphocyte of acute ischemic stroke patients. Target genes for the deregulated miRNAs were predicated using the online bioinformatic algorithms and functional annotation via Kyoto encyclopedia of genes and genomes pathway analysis for miRNAs predicted targets was carried out. Based on the predicted target genes of differentially expressed miRNAs, the miRNA-gene-network and miRNA-pathway-network were constructed.@*RESULTS@#Yang score based on tongue texture, urine, dejecta, and appearance, etc. showed that clinical symptoms were distinct between yang and yin syndromes. There were significantly higher total leukocyte number and lower total protein level in patients with yang syndrome compared with those in patients with yin syndrome (P<0.05). Comprehensive miRNA analysis identified 36 unique down-regulated miRNAs in yang syndrome group, and 20 unique down-regulated and 2 unique up-regulated miRNAs in yin syndrome group. The key regulatory miRNAs, gene, and pathways in the yang syndrome were hsa-miR-93-5p and -320b, enabled homolog, the metabolic pathways and mitogen-activated protein kinase signaling pathways, respectively, while those in the yin syndrome were hsa-miR-424-5p and -106b-5p, CNOT4, hepatitis B and pathways in cancer, respectively.@*CONCLUSION@#These results offered insight into the molecular basis underlying the different pathogenesis of yang or yin syndrome, providing clues for the individualized therapeutic strategies of acute ischemic stroke.
RESUMEN
Objective To observe the therapeutic effect of DENG Tie-tao's Foot-bath Recipe (mainly composed of Radix Achyranthis Bidentatae,Rhizoma Chuanxiong,Spica Prunellae,Fructus Evodiae,Ramulus Uncariae Cum Uncis,etc.)for the treatment of essential hypertension with hyperactivity of liver Yang syndrome. Methods Eighty essential hypertension patients with hyperactivity of liver Yang syndrome were randomly divided into treatment group and control group,40 cases in each group. Both groups were given basic antihypertensive western medicine treatment, and additionally the treatment group was given external application of DENG Tie-Tao's Foot-bath Recipe and the control group was given foot-bath with warm water. Seven days constituted one treatment course. Before and after treatment , the scores of traditional Chinese medicine(TCM)symptoms and Athens Insomnia Scale were observed , blood pressure variability (BPV)was detected with ambulatory blood pressure monitoring instrument , and plasma norepinephrine(NE) and epinephrine(E) levels were examined by enzyme-linked immunosorbent assay (ELISA). Results (1)The total effective rate for improving TCM symptom scores of the treatment group was 87.5%, and that of the control group was 75.0% , the difference being significant (P < 0.05). (2)The total effective rate for lowering blood pressure of the treatment group was 85.0%, and that of the control group was 72.5% , the difference being significant (P < 0.05). (3)After treatment,scores of Athens Insomnia Scale in the two groups were obviously decreased(P<0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group (P <0.01). (4)After treatment,24h BPV,daytime BPV and night BPV in the two groups were decreased to certain degrees (P < 0.05 compared with those before treatment),and the decrease of 24h BPV and night BPV in the treatment group was superior to that in the control group(P<0.05).(5)After treatment,plasma NE and E levels in the two groups were decreased to certain degree (P < 0 . 05 compared with those before treatment), and the decrease in the treatment group was superior to that in the control group (P < 0.05). Conclusion DENG Tie-Tao's Foot-bath Recipe exerts synergistic action on lowering blood pressure steadily by relieving TCM symptoms, improving the quality of sleep, decreasing 24hBPV of essential hypertension with hyperactivity of liver yang syndrome. And the regulation of plasma NE and E levels may be one of its therapeutic mechanisms.
RESUMEN
“Three Yin and Three Yang” syndrome differentiation is a method and system generated from “Treatise on Febrile Diseases”. And it is a principle of syndrome differentiation and a criterion of treatment. Modern physicians give many descriptions on levels of “Three Yin and Three Yang” syndrome differentiation. There are a lot of different opinions on it, including “Yin and Yang”, ”three steps of Cluster analysis”, “one divided into two” combining with “one divided into three”, and “three steps of recognizing symptom, understanding disease and differentiating syndrome” theories. The author believes “Three Yin and Three Yang”syndrome differentiation consists of three levels:differentiating syndrome principle, differentiating syndrome category and differentiating syndrome type. Strengthening research on levels of syndrome differentiation helps to improve accuracy of syndrome differentiation, guide drug description and enhance clinical efficacy.
