Ontology highlight
ABSTRACT: Psoriasis is chronic skin disease and an important health concern. Traditional Chinese Medicine (TCM) has shown great promise in the treatment of psoriasis. However, the correlation between TCM Syndromes and genomics of psoriasis has not been evaluated. Here, we analyzed gene expression profiling of monocytes from psoriasis vulgaris patients with different TCM syndrome types to reveal the molecular basis of different psoriasis syndromes. Of the 62 cases of psoriasis vulgaris recruited, 16, 23, and 23 cases were of blood-heat syndrome, blood stasis syndrome, and blood-dryness syndrome, respectively; 10 healthy controls were recruited as controls. Affymertix's Gene Chip ®clariom D gene chip was used to detect the gene expression profile of peripheral blood monocytes collected from recruited individuals. Compared with the healthy control group, 1570 genes were up-regulated and 977 genes were down-regulated in the psoriasis vulgaris patients group; 798 genes and 108 genes were up- and down-regulated in the blood-heat syndrome group respectively; 319 and 433 genes were up- and down-regulated in the blood-dryness syndrome group, respectively; and 502 and 179 genes were up-and down-regulated in the blood-stasis syndrome group. Our analyses indicated not only common differential genes and pathways between psoriasis syndrome groups and healthy controls, but also syndrome-specific genes and pathways. The results of this study link the three syndromes at the gene level and will be useful for clarifying the molecular basis of TCM syndromes of psoriasis.

Project description:Traditional Chinese medicine emphasizes treatment based on syndrome differentiation. This study aimed to clarify the characteristics of DNA methylation expression profiles in peripheral blood mononuclear cells in patients with psoriasis and analyze the differences in these profiles among different traditional Chinese medicine syndromes of psoriasis in order to provide a material basis for the diversity of these syndromes. Blood samples were collected from 32 participants, including 13 patients with psoriatic blood heat syndrome, 13 patients with psoriatic blood stasis syndrome, and 6 healthy controls. Peripheral blood mononuclear cells were extracted and subjected to DNA quality inspection. An Illumina Human Methylation 850k chip was used to sequence each group of samples. After screening out differentially methylated sites, the distribution of the corresponding differentially methylated genes on the chromatin was determined. According to gene annotation classification and CpG island annotation classification, the differentially methylated regions between sample groups were screened, and Gene Ontology and KEGG pathway analyses were used to perform functional analysis of differentially methylated genes. Finally, the differentially methylated genes closely correlating with psoriasis severity were screened using Spearman’s correlation analysis.

Project description:In traditional Chinese medicine (TCM), blood stasis syndrome (BSS) is mainly manifested by the increase of blood viscosity, platelet adhesion rate and aggregation, and the change of microcirculation, resulting in vascular endothelial injury. It is an important factor in the development of diabetes mellitus (DM). According to the differences in the internal and external environment of the individual disease, BSS were divided into qi-deficiency and blood stasis syndrome (QDBS), qi-stagnation and blood stasis syndrome (QSBS), cold-coagulation and blood stasis syndrome (CCBS), heat-accumulation and blood stasis syndrome (HABS). The aim of this study was to screen out the potential candidate mRNAs in DM patients with BSS by high-throughput sequencing (HTS) and bioinformatics analysis. CRL-1730 human umbilical vein endothelial cells (HUVECs) were incubated with 10% human serum to establish models of DM with BSS, DM without BSS (NBS) and normal control (NC). Total RNA of each sample was extracted and sequenced by the Hiseq2000 platform. Differentially expressed mRNAs (DE-mRNAs) were screened between samples. On the basis of mRNA expression profiles, four comparisons were made, including QDBS vs NBS and NC, QSBS vs NBS and NC, CCBS vs NBS and NC, HABS vs NBS and NC. Then, comparisons with P values <0.05 (Fisher's exact test), false discovery rates (FDR) <0.01 and |log2 ratios|≥1 were considered as DE-mRNAs in BSS. This study screened out the DE-mRNAs in DM patients with BSS by HTS and bioinformatics analysis.
Project description:Qi deficiency blood stasis (QDBS) and Yin deficiency blood stasis (YDBS) are the two major subtypes of which according to the traditional Chinese medicine. This study was conducted to distinguish these two syndromes at transcriptomics level and explore the underlying mechanisms.
Project description:Based on UPLC-Q-TOF-MS metabolomics technology, urine samples of 1072 subjects from 9 centers, including normal control, phlegm and blood stasis (PBS) syndrome and Qi and Yin deficiency (QYD) syndrome, and other syndromes of CHD, were conducted to find biomarkers. Among them, the discovery set (n = 125) and the test set (n = 337) were used to identify and validate biomarkers, and the validation set (n = 610) was used for the application and evaluation of the support vector machine (SVM) prediction model.

Project description:To explore the biological connotation of eight syndromes of Rheumatoid Arthritis (RA) from the syndrome-symptom association network, and the relationship between the clinical characteristics of various syndromes and their key network target genes and pathways, which may offer clinicians auxiliary tools for diagnosis and treatment of RA patients with various traditional Chinese medicine (TCM) syndromes and promoting the developments of TCM Syndrome Theory. We used microarrays to detail the biological connotation of five syndromes (D-H, N) of Rheumatoid Arthritis (RA) and identified distinct classes of up-regulated and down-regulated genes during this process.
Project description:Objective: This study aimed to identify the differentially expressed genes and related biological processes in dyslipidemia with the Phlegm-Dampness Retention (PDR) syndrome and the Spleen and Kidney Yang Deficiency (SKYD) syndrome using transcriptomic analysis. Methods: Ten ApoE knockout (ApoE-/-) mice were used for the establishment of dyslipidemic disease-syndrome models via multifactor-hybrid modeling, with 5 in the the PDR group and 5 in the SKYD group. Five C57BL/6J mice were employed as normal controls (NC) group, which is not included in the current records.. Test model quality. Aortic endothelial macrophages in mice were screened using flow cytometry. Transcriptomic analysis was performed for macrophages using RNA-Seq. Results: The quality assessment of the disease-syndrome model showed that TG, TC, and LDL-C levels significantly increased in the PDR and SKYD groups versus the NC group (P < 0.05). Combined with HE staining of aorta, the disease model was successfully established. The quality assessment of the syndrome models showed that mice in the PDR group presented with typical manifestations of the PDR syndrome, and mice in the SKYD group had the related manifestations of the SKYD syndrome, indicating that the syndrome models were successfully constructed. After comparing the differentially expressed gene (DEG) expressions in macrophages in dyslipidemia mice with different syndromes, 4142 genes were identified with statistical significance (P < 0.05). The Gene Ontology (GO) analysis for the DEGs showed that biological process of difference between PDR group and SKYD group include both adverse and protective processes were included. Conclusion: The DEGs between the PDR syndrome and the SKYD syndrome indicate different biological mechanisms between the onset of the two syndromes. They have distinctive biological processes, including adverse and protective processes, corresponding to the invasion of pathogenic factors into the body and the fight of healthy qi against pathogenic factors, respectively, in the TCM theory. Our results have demonstrated the biological evidence behind ‘treating the same disease with different treatments’ in TCM.
