Combined Therapies of Traditional Chinese Medicine Treat Low-prognosis Patients Undergoing IVF-ET Again / 中国实验方剂学杂志

ObjectiveTo objectively evaluate the clinical efficacy of multiple therapies of traditional Chinese medicine （TCM） in low-prognosis patients who received antagonist protocol for in vitro fertilization and embryo transfer （IVF-ET） again. MethodA total of 128 patients with kidney Yin deficiency， liver depression， and blood stasis who planned to receive antagonist protocol for IVF-ET in the West China Second Hospital of Sichuan University were enrolled and assigned into two groups by random number table method. The observation group （64 casces） was treated by oral administration of Chinese medicine decoction + enema of kidney-tonifying and blood-activating method + auricular point sticking + oral administration of dehydroepiandrosterone （DHEA）， while the control group （64 casces） was treated by only oral administration of DHEA. After treatment for three menstrual cycles， both groups received the antagonist protocol for IVF-ET. The TCM syndrome scores， basic sex hormone levels， antral follicle count （AFC）， the usage of gonadotropin （Gn）， endometrial receptivity indicators， embryo quality indicators， and pregnancy outcomes were compared between the two groups. ResultAfter treatment， the observation group showed decreased follicle-stimulating hormone （FSH）/luteinizing hormone （LH） ratio， lowered level of estradiol （E2）， increased AFC， decreased amount and days of Gn usage， improved endometrial receptivity indicators （endometrial thickness on trigger and ET days， proportion of endometrial type A in endometrial types and the level of E2 on trigger day） and embryo quality indicators （the rates of mature follicles， fertilization， normal fertilization， and premium embryos）， and decreased TCM syndrome scores （P<0.05， P<0.01）. Moreover， the observation group had lower FSH/LH ratio， E2 level， and amount of Gn usage， higher AFC， poorer endometrial receptivity and embryo quality indicators， and lower TCM syndrome scores than the control group after treatment （P<0.05， P<0.01）. In addition， except for 3 cases of natural pregnancy， the observation group outperformed the control group in terms of improving the clinical pregnancy rates during initiation cycle and transplantation cycle and clinical pregnancy rate and decreasing biochemical pregnancy rate and early abortion rate （P<0.05）. ConclusionCombined therapies of TCM can alleviate the clinical symptoms， reduce TCM syndrome scores， reduce the Gn usage amount， improve the number and quality of embryos and endometrial receptivity， and coordinate the synchronous development of endometrium and embryo. In this way， they can increase the clinical pregnancy rate and reduce biochemical pregnancy rate and early abortion rate in the low prognosis patients with kidney yin deficiency， liver depression， and blood stasis who are undergoing IVF-ET again.

Exploring Modern Mechanism of Treating Diabetic Retinopathy and Coronary Heart Disease from Perspective of Blood Stasis Under Viewpoint of Treating Different Diseases with the Same Method / 中国实验方剂学杂志

Diabetic retinopathy（DR） and coronary heart disease（CHD） are both major chronic vascular complications that seriously jeopardize the health of the population and often occur together in clinical practice， it is of great clinical value to actively explore the association between the two in the process of disease development and methods of prevention and treatment of modern medicine and traditional Chinese medicine（TCM）. According to TCM， the heart and eyes physiologically communicate with each other by taking Qi， blood and veins as bridges， blood stasis obstructing collaterals is the common TCM etiology of DR and CHD， whose mechanism involves inflammation， oxidative stress and endothelial dysfunction. Promoting blood circulation and removing blood stasis plays an important role in the same treatment for different diseases and prevention and treatment of comorbidities， possibly by inhibiting the expression of interleukin-1β（IL-1β）， endothelin-1（ET-1） and hypoxia inducible factor-1α/vascular endothelial growth factor（HIF-1α/VEGF）， regulating phosphatidylinositol 3-kinases/protein kinase B/mammalian target of rapamycin（PI3K/Akt/mTOR） pathway， initiating adenosine monophosphate（AMP）-activated protein kinase/silent information regulator 1（AMPK/SIRT1） and nuclear transcription factor erythroid 2-related factor 2/heme oxygenase-1（Nrf2/HO-1） signaling pathways， inhibiting Hippo/Yes-associated protein（Hippo/YAP） signaling pathway， inhibiting mitochondrial permeability transition pore and anti-platelet agglutination for treating DR and CHD， which provides a multi-component， multi-pathway and multi-target selection strategies and ideas for the prevention and treatment of DR and CHD by TCM from a biological perspective. Based on this， subsequent studies should focus on constructing clinically relevant comorbidity models， conducting multicenter prospective studies， and fully utilizing artificial intelligence technology to gain a deeper understanding of the relationship between the two diseases， so as to elucidate the mechanism of promoting blood circulation and removing blood stasis in preventing and treating panvascular diseases.

Exploring biological connotation of blood stasis syndrome of rheumatoid arthritis and establishment of improved animal models based on syndrome-symptom mapping / 药学学报

Blood stasis syndrome is one of the core clinical syndrome of rheumatoid arthritis (RA), but the biological connotation of this syndrome is not clear, and there is a lack of disease improved animal models that match the characteristics of this disease and syndrome. The aim of this study was to screen the candidate biomarker gene set of blood stasis syndrome of RA, reveal the biological connotation of this syndrome, and explore and evaluate the preparation method of the improved animal model based on the characteristics of "disease-syndrome-symptom". The study was approved by the ethics committee of Guang'anmen Hospital, Chinese Academy of Traditional Chinese Medicine (No. 2019-073-KY-01) and the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine (No. TYLL2021[K]018), and the study subjects gave their informed consent. Animal welfare and experimental procedures followed the regulations of the Experimental Animal Ethics Committee of the Chinese Academy of Traditional Chinese Medicine (No. IBTCMCACMS21-2207-01). The whole blood samples were collected clinically from RA patients with blood stasis syndrome (3 cases) or other syndromes (7 types, 3 cases/type), and healthy volunteers (4 cases), and then transcriptome sequencing, KEGG, gene set enrichment analysis (GSEA) and weighted correlation network analysis (WGCNA) analysis were performed. 126 pivotal genes were screened, and their functional annotation results were significantly enriched in "immune-inflammation" related pathways and lipid metabolism regulation (sphingolipids, ether lipid metabolism and steroid biosynthesis). Syndrome-symptom mapping of hub gene set to the TCM primary and secondary symptoms, Western phenotypic symptoms and pathological links showed that joint tingling, abnormal joint morphology, petechiae and abnormal blood circulation are representative of blood stasis syndrome of RA. The results of the improved animal model showed that the rats in the collagen-induced arthritis + adrenaline hydrochloride (CIA+Adr) 3 model group had increased blood rheology, coagulation, platelet function and endothelial function abnormalities compared with the CIA-alone model group, suggesting that the rats with blood stasis syndrome of RA may be in a state of "blood stasis". The results of the study can help to advance the objective study of the evidence of blood stasis syndrome in RA, and provide new ideas for the establishment of an animal model that reflects the clinical characteristics of the disease and syndrome.

ObjectiveTo observe the clinical effect of Yiqi Liangxue Shengji Formula （益气凉血生肌方， YLSF） on recurrence of angina pectoris and quality of life at eight weeks after perecutaneous coronary intervention （PCI）. MethodsEighty-two coronary artery disease （CAD） patients with qi deficiency and blood stasis and binding of stasis and heat syndrome who had underwent PCI were randomly divided into two groups with 41 patients each in the treatment group and the control group. Based on conventional western medicine after PCI， patients in the treatment group orally took YLSF granules while those in the control group were administered with placebo， one dose daily for 8 weeks. The recurrence rate of angina pectoris and readmission rate within eight weeks after PCI were recorded. Before and after treatment， total traditional Chinese medicine （TCM） syndrome score， Seattle Angina Questionnaire （SAQ） scores （physical limitation， angina stability， angina frequency， treatment satisfaction and disease perception）， and the SF-36 scores for quality of life （physical and mental health） were evaluated. The adverse reactions during medication in both groups were recorded. ResultsWithin eight weeks after PCI， the recurrence rate of angina pectoris in the treatment group （4/41， 9.76%） was significantly lower than that in the control group （11/41， 26.83%， P＜0.05）. The readmission rate in the treatment group was 2.44% （1/41）， while that in the control group was 12.20% （5/41）， with no significantly statistical difference （P＞0.05）. After treatment， total TCM syndrome score significantly decreased in both groups， while in terms of quality of life， the SAQ scores on domains of angina stability， angina frequency and disease perception as well as SF-36 total scores， physical health and mental health scores significantly increased （P＜0.05 or P＜0.01）. Compared between the two groups， total TCM syndrome score was significantly lower in the treatment group than the control group （P＜0.01）， while no significant differences were found in SAQ scores and SF-36 total， physical and mental health scores （P＞0.05）. No adverse reactions occurred in both groups during the treatment period. ConclusionYLSF can reduce the recurrence rate of angina pectoris within eight weeks after PCI for coronary artery disease， and can improve the TCM syndrome score， and have sound safety， with comparable effect to that of placebo in improving postoperative short-term quality of life.

Mechanisms of Yangxin Tongmai Formula for blood stasis syndrome in coronary heart disease rats based on untargeted plasma metabolomics and intestinal flora 16S rRNA sequencing / 数字中医药（英文）

@#【Objective】  To investigate the correlations between intestinal flora, plasma metabolites, and blood stasis syndrome in coronary heart disease (CHD), and the mechanisms of Yangxin Tongmai Formula (养心通脉方, YXTMF) for blood stasis syndrome in CHD rats. 【Methods】  A total of 18 specific pathogen free (SPF) male Sqrague-Dawley (SD) rats were used to establish CHD rat models with blood stasis syndrome, which were then randomized into model, YXTMF, and atorvastatin calcium (AVT) groups, with six rats in each group, and were intervened through gavage for two weeks. Subsequently, additional six rats that received normal diet were included as normal group. The pathological changes in the CHD rat models were identified by hematoxylin-eosin (HE) staining. The electrocardiogram, hemodynamics, and lipid profiles of the rats were detected as well. The untargeted plasma metabolomics of rats were analyzed by liquid chromotography-tandem mass spectrometry (LC-MS/MS), their ileal mucosal flora by 16S rRNA sequencing, and the correlation between the two results were also analyzed. 【Results】  The whole blood viscosity, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) of rats in the model group increased compared with those in the control group (P < 0.05). In the model group, the proliferation of endothelial cells in the coronary artery of rats was damaged, with quite a few vacuolated pathological changes observed. However, the endothelial lesions in the coronary artery of rats were alleviated in the intervention groups (YXTMF and AVT groups). With the use of  LC-MS/MS, a total of 33 potential endogenous metabolites were identified in plasma, among which 1-methylhistidine, N-acetylhistamine, progesterone, and deoxycorticosterone were expected to be the differential metabolites in CHD rats with blood stasis syndrome. The 16S rRNA sequencing results showed that improved diversity and abundance of intestinal flora were observed in the YXTMF group. The correlation analysis suggested that Hydrogenophaga, Limnohabitans, and Polaromonas, which were highly related to the formation of blood stasis syndrome in CHD patients, were positively correlated with plasma metabolites such as 5-hydroxyindole, N-acetylhistamine, and progesterone (P < 0.01), but were negatively correlated with plasma metabolites such as L-arginine, homoarginine, and Boc-beta-cyano-L-alanine (P < 0.01). After YXTMF intervention, Lactobacillus, Corynebacterium, and Candidatus Nitrososphaera were positively correlated with plasma metabolites such as Boc-β-cyano-L-alanine, stachydrine, and naringenin (P < 0.05), while negatively correlated with 5-hydroxyindole, N-acetylhistamine, and oleoylethanolamide (P < 0.05). 【Conclusion】  YXTMF could alleviate blood stasis syndrome in CHD rats through improving their plasma metabolisms achieved by regulating the intestinal flora.

The serum level of pepsinogen Ⅰ(PG Ⅰ), pepsinogen Ⅱ (PGⅡ) were detected by ELISA, and the PG Ⅰ/PG Ⅱ ratio was calculated. Gastroscopic biopsy was performed to observe the changes of intestinal metaplasia of gastric mucosa and glandular atrophy, and to evaluate the clinical efficacy.Results:The total responsive rate was 85.3% (29/34) in the study group and 58.8% (20/34) in the control group. There was significant difference between the two groups ( χ2=9.35, P=0.030). After treatment, the scores of stomachache, fullness of feeling in the observation group were significantly lower than those in the control group ( t=2.97, 3.80, P<0.05). After treatment, the level of serum PG Ⅰ[(76.21 ± 17.35) mg/L vs. (66.8 ± 18.77) mg/L, t=2.15] and PG Ⅰ/PG Ⅱ [(4.67 ± 0.99) vs. (3.90± 1.25), t=2.81] in the study group were significantly higher than those in the control group ( P<0.05), and PG Ⅱ [(16.36 ± 1.85) mg/L vs. (17.42 ± 2.05) mg/L, t=2.24] was significantly lower than that of the control group ( P<0.05). After treatment, intestinal metaplasia and glandular atrophy was significantly more improved or reversed than those in the control group ( χ2=20.67,9.33, P<0.05). Conclusion:The methods of activating blood and removing blood stasis, invigorating the spleen and soothing the liver can reverse the precancerous lesions of patients with gastric collateral stasis syndrome of chronic atrophic gastritis and have a good prognosis.

Objective:To observe the effects of TCM compounds for eliminating phlegm and removing blood stasis on the ultrastructure of atrial myocardium in atrial fibrillation (AF) rats; To explore its possible mechanism.Methods:Totally 60 male SD rats were divided into blank group (10 rats) and model group (50 rats) according to random number table method. The atrial fibrillation model was established by tail vein injection of ACh-CaCl 2 mixture for 7 consecutive days, and then the rats with successful modeling were divided into model group, verapamil group, TCM compounds high-, medium- and low-dosage groups according to random number table method, with 10 rats in each group. TCM compounds high-, medium- and low-dosage groups were given Chinese herbal decoction 41.25, 20.63, 10.31 g/(kg?d) by gavage, respectively, and the verapamil group was given verapamil solution 25 g/(kg?d). The blank group and the model group were given an equal volume of normal saline by gavage for consecutive 14 days. After 14 consecutive days, electrophysiological recorder was used to measure the duration of atrial fibrillation in each group of rats; the changes of ultrastructure of atrial myocytes in each group were observed under transmission electron microscope; serum ROS, SOD and GSH-Px levels of rats were detected by ELISA. Results:Compared with the model group, the duration of atrial fibrillation in TCM compounds high-, medium- and low-dosage groups and verapamil group decreased ( P<0.05); the ultrastructural damage of atrial myocytes was improved; the content of ROS [(139.20±3.34) ng/ml,(139.00±3.28) ng/ml, (139.25±3.82) ng/ml vs. (155.60±7.32) ng/ml] in TCM compounds high- and medium-dosage groups and verapamil group decreased; the contents of SOD [(2.41±0.26) ng/ml, (2.40±0.12) ng/ml, (2.37±0.06) ng/ml vs.(2.12±0.21) ng/ml] increased ( P<0.05); the content of GSH-Px [(3.61±0.06) ng/ml, (3.60±0.08) ng/ml, (3.47±0.15) ng/ml, (3.51±0.19) ng/ml vs.(3.27±0.12) ng/ml] in TCM compounds high-, medium- and low-dosage groups and verapamil group increased ( P<0.05). Conclusion:TCM compounds for eliminating phlegm and removing blood stasis can shorten the duration of atrial fibrillation in rats, reduce the damage of ultrastructure of atrial myocytes in AF rats, regulate the expressions of serum ROS, SOD and GSH-Px in AF rats, and inhibit oxidative stress, which may be one of its mechanisms of action in the treatment of atrial fibrillation.

Syndrome Distribution and Characteristics of Endometriosis in 1 895 Cases / 中国实验方剂学杂志

ObjectiveTo explore the distribution and characteristics of traditional Chinese medicine （TCM） syndromes in patients with endometriosis （EMS）. MethodA cross-sectional survey was conducted to analyze the characteristics of TCM syndromes in 1 895 cases of EMS in hospitals of 19 provinces， autonomous regions， and municipalities. ResultAmong the 1 895 patients， Qistagnation and blood stasis syndrome accounted for the highest proportion， followed by Qi deficiency and blood stasis syndrome， cold coagulation and blood stasis syndrome， and kidney deficiency and blood stasis syndrome. The distribution of TCM syndrome types of patients with EMS in different regions， different treatment stages， and different disease types and with different therapeutic goals was different， and the differences were statistically significant. However， under different conditions， the Qi stagnation and blood stasis syndrome accounted for the highest proportion. Under the stratification of different regions， the cold coagulation and blood stasis syndrome in north China was relatively high， the kidney deficiency and blood stasis syndrome in south China was relatively high， and the combined phlegm and stasis syndrome was relatively high in southwest China. Different diagnosis and treatment goals corresponded to different clinical syndromes. With pelvic pain as the main manifestation， the proportion of cold coagulation and blood stasis syndrome was higher. The proportion of kidney deficiency and blood stasis syndrome was higher in married patients with infertility. Patients with the main diagnosis and treatment goals of controlling mass and inhibiting recurrence had a higher proportion of Qi deficiency and blood stasis syndrome. In different treatment stages， the proportion of Qi deficiency and blood stasis syndrome in postoperative patients and those with recurrent EMS was higher. Among different disease types， the Qi deficiency and blood stasis syndrome accounted for a higher proportion in patients with ovarian endometriosis （OEM）. The cold coagulation and blood stasis syndrome accounted for a higher proportion in patients with deep invasive endometriosis （DIE）. The kidney deficiency and blood stasis syndrome accounted for a higher proportion in patients with peritoneal EMS. There were significant differences in age， body mass index （BMI）， and course of disease among patients with different syndromes. Patients with Qi deficiency and blood stasis syndrome was relatively older， and their course of the disease was relatively long. Patients with combined phlegm and stasis syndrome had relatively high BMI. There was no significant difference in CA125 and CA199 levels among all syndrome types. ConclusionThe distribution of TCM syndromes of EMS has a certain regularity， and there are differences in regional distribution， therapeutic goals， treatment stages， and disease types（P<0.05）. However， the Qi stagnation and blood stasis syndrome accounts for a large proportion under different conditions， suggesting that Qi stagnation is the key link of EMS. In the early stage， the team took relieving depression and activating blood as the primary treatment， and created Huoxue Xiaoyi prescription， which was the core prescription for the treatment of EMS with Qi stagnation and blood stasis syndrome， achieving good clinical effect. At the same time， it is emphasized that EMS treatment should be integrated into the concept of chronic disease management and combined with health management. Through psychological counseling， cognitive behavior intervention， popular science lectures， and other methods， it is advised to adjust the emotion of patients with EMS， thereby increasing the curative effect. This study is expected to provide references for the clinical treatment of EMS.

Observation of the therapeutic effect of Tongyuan needling combined with jingyu herb-separated moxibustion on recurrent implantation failure of kidney deficiency and blood stasis / 中国针灸

OBJECTIVES@#To observe the therapeutic effect of Tongyuan needling combined with jingyu herb-separated moxibustion on the patients with recurrent implantation failure (RIF) of kidney deficiency and blood stasis undergoing frozen embryo transfer of the conventional hormone replacement therapy cycle.@*METHODS@#Sixty RIF of kidney deficiency and blood stasis patients who planned for frozen embryo transfer were randomly divided into a combined treatment group (30 cases) and a western medication group (30 cases). In the western medication group, the conventional hormone replacement therapy was performed for endometrial preparation during transfer cycle. On the basis of treatment as the western medication group, in the combined treatment group, Tongyuan needling combined with jingyu herb-separated moxibustion was adopted. Regarding tongyuan needling, the acupoint prescription for Tongdu Tiaoshen (promoting the governor vessel and regulating the spirit, e.g. Dazhui [GV 14], Ganshu [BL 18], Shenshu [BL 23] and back-shu points) and that for Yinqi Guiguan (conducting qi back to the primary, e.g. Zhongwan [CV 12], Qihai [CV 6], Guanyuan [CV 4] and front-mu points) were selected. Acupuncture was delivered at these two prescriptions alternatively each time. After acupuncture, the herb-separated moxibustion (in which, the herbal powder was prepared with the modified Yangjing Zhongyu decoction for cultivating the kidney essence and promoting pregnancy) was operated at Shenque (CV 8). This combined therapy was delivered once every two days, 3 sessions a week till the day of embryo transfer. The pregnancy outcomes (positive rate of human chorionic gonadotropin [β-HCG] and clinical pregnancy rate) were compared between the two groups, as well as the TCM syndrome score, serum estradiol (E2) and progesterone (P) levels, endometrial thickness and type, endometrial blood flow index (pulsatility index [PI], resistance index [RI]) before and after treatment.@*RESULTS@#After treatment, the clinical pregnancy rate of the combined treatment group was 40.0% (12/30), higher than that of the western medication group (16.7%, 5/30, P<0.05); and the difference in the positive rate of β-HCG was not significant statistically between the two groups (P>0.05). After treatment, the serum levels of E2 and P were elevated (P<0.05), the endometrial thickness was thickened (P<0.05); the scores of TCM syndrome, and the levels of PI and RI were reduced (P<0.05) when compared with those before treatment in the two groups. The proportion of type A endometrium increased compared with that before treatment in the combined treatment group (P<0.05). Except the levels of E2 and P, the above indexes in the combined treatment group were superior to the western medication group (P<0.05).@*CONCLUSIONS@#On the basis of frozen embryo transfer of conventional hormone replacement cycle, the intervention of Tongyuan needling combined with jingyu herb-separated moxibustion can effectively relieve the clinical symptoms, increase the endometrial blood flow and its thickness, and improve the endometrial receptivity, thereby ameliorate pregnancy outcomes in RIF patients of kidney deficiency and blood stasis.

Moxibustion combined with western medication for rheumatoid arthritis with blood stasis obstruction and its effect on platelet activation / 中国针灸

OBJECTIVE@#To investigate the clinical efficacy and action mechanism of moxibustion combined with western medication for rheumatoid arthritis (RA) with blood stasis obstruction.@*METHODS@#Fifty-six patients of RA with blood stasis obstruction were randomly divided into an observation group and a control group, with 28 patients in each group. The patients in the control group were treated with oral administration of leflunomide tablets and celecoxib capsules, while the patients in the observation group were treated with moxibustion in addition to the treatment used in the control group. Moxibustion was performed at bilateral Zusanli (ST 36), Shenshu (BL 23), Xuehai (SP 10), and ashi points, once every other day, three times a week. The treatment duration for both groups was 12 weeks. The TCM syndrome score, disease activity score-28 (DAS-28), rheumatoid factor (RF), hypersensitive C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), hemorheological indexes (whole blood viscosity high shear, whole blood viscosity low shear, plasma viscosity), serum calcium ion (Ca2+) level, and platelet count (PLT) were observed before and after treatment, and the clinical efficacy was evaluated after treatment in the two groups.@*RESULTS@#Compared with those before treatment, the TCM syndrome scores, DAS-28 scores, RF, hs-CRP, ESR, whole blood viscosity high shear, whole blood viscosity low shear, plasma viscosity, and PLT were decreased after treatment in both groups (P<0.01), with the observation group showing lower values compared with those in the control group (P<0.05). Compared with those before treatment, the serum Ca2+ levels were increased after treatment in both groups (P<0.01), and the observation group showed a higher increase than that in the control group (P<0.05). The total effective rate was 85.7% (24/28) in the observation group, which was higher than 67.9% (19/28) in the control group (P<0.05).@*CONCLUSION@#Moxibustion combined with western medication could alleviate clinical symptoms in patients with RA of blood stasis obstruction, and its mechanism may be related to the inhibition of platelet activation.

Experimental and clinical research progress of traditional Chinese medicine promoting blood circulation and removing blood stasis in treatment of pulmonary hypertension / 中国药理学通报

Pulmonary hypertension(PH)is a type of progressive cardiovascular disease or clinical syndrome. Its pathological mechanism is complex. The existing clinical drugs cannot well inhibit the progression of the disease. Traditional Chinese Medicine(TCM)has unique advantages in the treatment of PH due to its synergistic effect of multiple components and multiple targets. Recent studies have found that the TCM of promoting blood circulation and removing blood stasis can play a significant role in the treatment of PH, such as dilating pulmonary blood vessels, improving endothelial function, and relieving right heart failure. This article briefly summarizes and discusses the therapeutic effect and mechanism of TCM that can promote blood circulation and remove blood stasis in treatment of PH.

Differential expression profiles analysis of DNA methylation between “disease” and “syndrome” in coronary heart disease-induced unstable angina patientswith Qi deficiency and blood stasis syndrome / 数字中医药（英文）

Objective@#To explore the differential expression profiles of DNA methylation sites/regions and potential molecular mechanisms in the peripheral blood of coronary heart disease (CHD)-induced unstable angina pectoris patients with or without Qi deficiency and blood stasis syndrome, and to provide scientific evidence for the conbination of disease and syndrome.@*Methods@#According to the pre-determined inclusion and exclusion criteria, the study subjects were enrolled and divided into two groups namely CHD-induced unstable angina group (G group) and healthy control group (J group) to conduct “disease” analysis, while G group was further divided into Qi deficiency and blood stasis syndrome group (case group) and non-Qi deficiency blood stasis syndrome group (control group) to perform “syndrome” analysis. The general data and clinical information of the study subjects were collected. The peripheral venous blood was extracted on an empty stomach, and the Illumina Infinium MethylationEPIC BeadChip (850K methylation chip) was used to detect the differential expressionprofiles of DNA methylation in each group, ChAMP software (V 2.14.0) was used for the differential methylation data analysis, with a threshold of the adjusted P value (adj.P.val) < 0.01. Gene Ontology (GO) and Kyoto Encyclopedia of Genomes (KEGG) were employed for the functional and pathway enrichment analyses of related mapped genes.@*Results@#A total of 263 differentially methylated CpG positions (DMPs) were screened out between G and J groups, including 191 hypermethylated positions such as cg05845204 and cg08906898, and 72 hypomethylated positions such as cg26919182 and cg13149459. These positions were mainly mapped to 148 genes encompassing RNA binding motif protein 39 (RBM39), acetyl-CoA acyltransferase 2 (ACAA2), protein phosphatase 1 regulatory subunit 12B (PPP1R12B), and the dual-specificity tyrosine phosphorylation-regulated kinase 2 (DYRK2). GO functional enrichment analysis revealed that the genes of the DMPs were primarily enriched in protein localization to chromosomes, regulation of cell morphogenesis, negative regulation of calcium-mediated signals, etc. KEGG pathway analysis suggested that the genes were mainly enriched in fatty acid metabolism and endocytosis pathways. In addition, a total of 23 differential methylation regions (DMRs) were identified, with overlapping genes such as transmembrane protein 232 (TMEM232), ribosomal protein large P1 (RPLP1), peroxisomal biogenesis factor 10 (PEX10), and forkhead box N3 (FOXN3) recognized. It was found that GO functions were mainly enriched in the negative regulation of Ras protein signal transduction, small GTPase-mediated signal transduction, negative regulation, etc. A total of 1 703 differential methylation sites were screened out between case and control groups, including 444 increased methylation positions such as cg05573767 and 1 259 decreased methylationpositions such as cg19938535, and cg03893872. These positions were mapped to 1 108 genes such as ribosomal protein S6 kinase A2 (RPS6KA2), leucine rich repeat containing 16A (LRRC16A), and hedgehog acyltransferase (HHAT). According to the GO functional enrichment analysis, the genes relating to the DMPs were mainly enriched in biological functions such as transmembrane receptor protein serine/threonine kinase signaling pathway and axonogenesis. The KEGG pathway enrichment analysis suggested the involvement of Rap1 signaling pathway, adenosine 5’-monophosphate-activated protein kinase (AMPK) signaling pathway, etc. A total of 21 DMRs were identified, including 22 overlapping genes such as mucin 4 (MUC4), three prime repair exonuclease 1 (TREX1), and LIM homeobox 6 (LHX6). GO analysis demonstrated that the genes primarily participated in molecular functions such as positive regulation of transmembrane transport, regulation of fatty acid metabolism, and copper ion binding.@*Conclusion@#This study reveals the methylation patterns of DMPs and DMRs in patients with Qi deficiency and blood stasis syndrome caused by CHD-induced unstable angina pectoris. Potential epigenetic regulation of fatty acid metabolism, Rap1 signaling, and other molecular functions are involved in the development of CHD between the "disease" and "syndrome".
