RESUMEN
BACKGROUND: Astragalus polysaccharide (APS) is a major bioactive component of the Chinese herb astragalus, with well-established protective effects on the kidney. However, the effect of APS on diabetic nephropathy (DN) is unclear. METHODS: Long non-coding RNA (lncRNA) expression profiles in kidney samples from control, db/db, and APS-treated db/db mice were evaluated using RNA high-throughput sequencing techniques. Additionally, rat renal tubular epithelial (NRK-52E) cells were cultured in high glucose (HG) media. We inhibited the expression of Gm41268 and prolactin receptor (PRLR) by transfecting NRK-52E cells with Gm41268-targeting antisense oligonucleotides and PRLR siRNA. RESULTS: We found that APS treatment reduced 24-h urinary protein levels and fasting blood glucose and improved glucose intolerance and pathological renal damage in db/db mice. Furthermore, APS treatment enhanced autophagy and alleviated fibrosis in the db/db mice. We identified a novel lncRNA, Gm41268, which was differentially expressed in the three groups, and the cis-regulatory target gene PRLR. APS treatment induced autophagy by reducing p62 and p-mammalian target of rapamycin (mTOR) protein levels and increasing the LC3 II/I ratio. Furthermore, APS alleviated fibrosis by downregulating fibronectin (FN), transforming growth factor-ß (TGF-ß), and collagen IV levels. In addition, APS reversed the HG-induced overexpression of Gm41268 and PRLR. Reduction of Gm41268 decreased PRLR expression, restored autophagy, and ameliorated renal fibrosis in vitro. Inhibition of PRLR could enhance the protective effect of APS. CONCLUSIONS: In summary, we demonstrated that the therapeutic effect of APS on DN is mediated via the Gm41268/PRLR pathway. This information contributes to the exploration of bioactive constituents in Chinese herbs as potential treatments for DN.

BACKGROUND Hypertension-related microRNA(miR)-1283 and its target gene, activating transcription factor-4 (ATF4), can regulate vascular endothelial dysfunction. This study aimed to explore whether miR-1283 prevents hypertension through targeting ATF4. MATERIAL AND METHODS Transcriptome sequencing was performed after overexpression or inhibition of miR-1283 in human amniotic epithelial cells (HAECs). After miR-1283 was overexpressed or inhibited in HAECs, ATF4+/- and wild-type mice were induced with a high-salt diet. We detected the expression of ATF4, C/EBP-homologous protein (CHOP), BH3-interacting domain death agonist (BID), Bcl-2, Bcl-2-like protein 11 (BIM), Bcl-2-like protein 1 (BCL-X), and caspase-3 by PCR and western blotting. We detected the changes of vasoactive substances including nitric oxide (NO), endothelin 1 (ET-1), endothelial protein C receptor (EPCR), thrombin (TM), and von Willebrand factor (vWF) by ELISA. RESULTS Compared with that of the miR-1283- inhibited group, NO was higher in the miR-1283 overexpression group, while the expression of ET-1, EPCR, TM, and vWF were lower. Similarly, compared with that of the miR-1283 inhibited group, the expression of ATF4, CHOP, BID, BIM, and caspase-3 in the miR-1283 overexpression group was downregulated, while the expression of BCL-2 and BCL-X was upregulated (P<0.05). In vivo experiments showed the lack of ATF4 gene could prevent hypertension in mice induced by high-salt diet and protect endothelial function. CONCLUSIONS The mechanism of regulating blood pressure and endothelial function of the miR-1283/ATF4 axis was related to inhibiting endoplasmic reticulum stress and cell apoptosis through the ATF4/CHOP signaling pathway. Therefore, the miR-1283/ATF4 axis may be a target for the prevention and treatment of hypertension.

BACKGROUND TaohongSiwu decoction (THSWT), a traditional herbal formula, has been used to treat cardiovascular and cerebrovascular diseases such as essential hypertension (EH) in China. However, the pharmacological mechanism is not clear. To investigate the mechanisms of THSWT in the treatment of EH, we performed compounds, targets prediction and network analysis using a network pharmacology method. MATERIAL AND METHODS We selected chemical constituents and targets of THSWT according to TCMSP and UniProtKB databases and collected therapeutic targets on EH from Online Mendelian Inheritance in Man (OMIM), Drugbank and DisGeNET databases. The protein-protein interaction (PPI) was analyzed by using String database. Then network was constructed by using Cytoscape_v3.7.1, and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment was performed by using Database for Annotation, Visualization and Integrated Discovery (DAVID) software. RESULTS The results of our network pharmacology research showed that the THSWT, composed of 6 Chinese herbs, contained 15 compounds, and 23 genes regulated the main signaling pathways related to EH. Moreover, the PPI network based on targets of THSWT on EH revealed the interaction relationship between targets. These core compounds were 6 of the 15 disease-related compounds in the network, kaempferol, quercetin, luteolin, Myricanone, beta-sitosterol, baicalein, and the core genes contained ADRB2, CALM1, HMOX1, JUN, PPARG, and VEGFA, which were regulated by more than 3 compounds and significantly associated with Calcium signaling pathway, cGMP-PKG signaling pathway, cAMP signaling pathway, PI3K-Akt signaling pathway, Rap1 signaling pathway, and Ras signaling pathway. CONCLUSIONS This network pharmacological study can reveal potential mechanisms of multi-target and multi-component THSWT in the treatment of EH, provide a scientific basis for studying the mechanism.

BACKGROUND: To evaluate the effectiveness and safety of HuoXueHuaYu (HXHY) therapy in treating nonalcoholic fatty liver disease (NAFLD) through a systematic review and meta-analysis. METHODS: We performed comprehensive searches on Embase, Pubmed, Cochrane Library, CNKI, VIP and Wanfang databases up to June 2017 for randomized controlled trials using HXHY in the treatment of NAFLD compared with conventional treatment. RESULTS: This meta-analysis included 13 studies involving 1429 patients which 775 patients belonged to HXHY group and 654 patients belonged to conventional treatment group. The results of meta-analysis showed that HXHY can significantly improve B ultrasonic level (OR = 2.33; 95% CI:1.60, 3.40; P < 0.00001) of NAFLD compared with conventional treatment. As to lipids, HXHY was tested to be better on reduction of total cholesterol (TC) (MD = -0.38, 95% CI: - 0.48, - 0.29; P < 0.00001) and triglyceride (TG) (MD = -0.31; 95% CI: - 0.37, - 0.24; P < 0.00001) than conventional treatment. HXHY also had a greater beneficial effect on liver function in reducing alanine transaminase (ALT) (MD = -1.69; 95% CI: - 2.24, - 1.14; P < 0.00001) and aspartate transaminase (AST) (MD = -22.53; 95% CI: - 33.16, - 11.90; P < 0.00001) compared with conventional treatment. HXHY can also significantly improve the effective rate (OR = 3.55; 95% CI:2.65, 4.76; P < 0.00001) compared with conventional treatment. No serious adverse reactions were reported. CONCLUSIONS: HXHY seems to be an effective and safe therapy for NAFLD. It is suggested that further study of HXHY in the treatment of NAFLD requires trials with rigorous design, multicenter, large-scale and high-quality worldwide.

BACKGROUND: Taohong Siwu Decoction (THSWD) is a classic prescription of traditional Chinese medicine. Recent research has shown that the practical components of THSWD have specific curative effects on various cardiovascular diseases, including hypertension, suggesting THSWD could effectively lower blood pressure (BP) with fewer side effects. However, little information is available regarding the effectiveness of THSWD combined with antihypertensive medicine on hypertension. OBJECTIVE: This meta-analysis aimed to study the efficacy and safety of THSWD in treating hypertension. METHODS: According to the search strategy, 8 databases were searched, including China Knowledge Network (CNKI), Wanfang Database, VIP Database, Pubmed, China Biomedical Literature Database (CBM), web of science, EMBASE and Cochrane Library, for the randomized controlled trial of THSWD on hypertension. 9 RCTs were included and 827 patients were involved. This meta-analysis used RevMan 5.4 to evaluate the articles. RESULTS: This review included 9 RCTs. All studies were THSWD with the antihypertensive drug compared with single antihypertensive western medicine. The total effective rate of THSWD combined with corresponding western medicine was significantly improved (Relative riskâ =â 1.26; 95% CI: 1.16-1.37, Pâ <â .00001), which could effectively reduce the systolic BP (MDâ =â -15.28 mm Hg; 95% CI: -20.17 to -10.40, Pâ <â .00001=, diastolic BP (MDâ =â -9.70 mm Hg; 95% CI: -12.66 to -6.73, Pâ <â .00001), Triglycerides (MDâ =â -1.48, 95%CI: -2.09 to -0.87, Pâ <â .00001), total cholesterol (MDâ =â -1.43, 95% CI: -1.63 to -1.24, Pâ <â .00001) and low density lipoprotein cholesterol (MDâ =â -0.93, 95% CI: -1.07 to -0.80, Pâ <â .00001). Compared with the single routine western medicine group, THSWD combined with the corresponding western medicine increased serum high-density lipoprotein (MDâ =â 0.41, 95% CI: 0.35 to 0.46, Pâ <â .00001). CONCLUSION: THSWD combined with antihypertensive drugs in treating hypertension was curative in lowering BP, improving blood lipid levels and reducing the incidence of adverse reactions compared to antihypertensive medications treatment. However, more high-quality studies are needed due to the biased results and the small number of studies for further verification of the effectiveness of THSWD, and providing a new treatment for clinical reference.

Objective: QiDan DiHuang decoction (QDD) has been proven to have good efficacy in decreasing albuminuria levels, improving renal function, and inhibiting renal fibrosis in diabetic nephropathy (DN). However, the potential mechanism remains unclear. The purpose of this study was to explore the underlying mechanism of QDD for treating DN in vitro and in vivo. Methods: Db/db mice were treated with QDD or saline intragastrically for 12 weeks. Non-diabetic db/m mice were used as controls. Rat renal tubular epithelial cells (NRK-52E) were cultured in high glucose conditions. ATF4 siRNA was transfected into NRK-52E cells. Different indicators were detected via UPLC, RT-PCR, western blotting, cell viability assays and apoptosis, transmission electron microscopy, histology, and immunofluorescence staining. Results: Db/db mice experienced severe kidney damage and fibrosis, increased levels of PERK, eIF2α, and ATF4, and suppression of renal autophagy compared with db/m mice. The results showed a significant improvement in glucose intolerance, blood urea nitrogen, urine albumin, serum creatinine, and renal fibrosis in db/db mice with QDD treatment. Meanwhile, the application of QDD resulted in the downregulation of PERK, eIF2α, and ATF4 and the upregulation of autophagy in diabetic kidneys. In vitro, the exposure of NRK-52E cells to high glucose resulted in downregulation of the ratio of LC3-II/LC3-I and upregulation of P62, a reduction in the number of autophagosomes and upregulation of fibronectin (FN), collagen IV and TGF-ß1 protein, which was reversed by QDD treatment through inhibiting ATF4 expression. Conclusions: Taken together, our results suggest that QDD effectively alleviates diabetic renal injuries and fibrosis by inhibiting the PERK-eIF2α-ATF4 pathway and promoting autophagy in diabetic nephropathy.
RESUMEN
Vitamin K2 (VK2), found to act to treat hypertension, has been widely used in the food and pharmaceutical industries nowadays. However, the potential targets and molecular mechanisms of VK2 for salt-sensitive hypertension have not been fully investigated. Therefore, the study aimed to investigate the potential molecular mechanisms of VK2 for salt-sensitive hypertension using network pharmacology and 16S rRNA sequencing strategy. The network pharmacology-based findings from KEGG enrichment analysis revealed that VK2-treated salt-sensitive hypertension was mechanically associated with the complement and coagulation cascades, calcium signaling pathway, renin-angiotensin system, etc. A total of 29 different bacteria in an animal experiment after VK2 supplementation were screened and functionally enriched using PICRUSt2. Additionally, 10 signaling pathways were identified in which the renin-angiotensin system was found to be the potential molecular mechanisms with the greatest change in multiple and statistical significance. Moreover, the results of the renin-angiotensin system-related protein expression exhibited VK2-inhibited renin-angiotensin system in salt-induced hypertensive mice, which significantly verified the previous biological and functional prediction analysis. Finally, spearman correlation analysis showed the different bacteria such as Dubosiella, Ileibacterium, etc., had a positive or negative correlation with renin-angiotensin system-related proteins in salt-induced mice. In conclusion, the potential molecular mechanisms of VK2 for salt-sensitive hypertension may be beneficially achieved by the specific inhibition of the renin-angiotensin system, contributing to the development for a new preventive strategy of salt-sensitive hypertension.
RESUMEN
AIM: Diabetic nephropathy (DN) is the dominant cause of end-stage renal disease which is characterized by extracellular matrix accumulation. The purpose of this study was to investigate the role of activating transcription factor 4 (ATF4) in regulating renal fibrosis and autophagy in DN. MAIN METHOD: Streptozotocin (STZ) was administered to heterozygous ATF4 knockout (KO) and wild-type (WT) mice via an intraperitoneal injection to induce DN. NRK-52E cells were cultured in high glucose to mimic diabetic pathological. qRT-PCR, western blot, immunofluorescence, histology and electron microscopic analysis were performed. The autophagy flux was observed by tandem mRFP-GFP-LC3 fluorescence microscopy. KEY FINDINGS: DN mice experienced severe renal injury and fibrosis and showed increased expression of ATF4 and inhibition of autophagy in kidney tissues. We found that STZ-induced ATF4 KO mice showed significant improvement in urinary albumin, serum creatinine and blood urea nitrogen and the pathological changes of renal tubulointerstitial fibrosis compared with STZ-induced WT mice. Furthermore, inhibition of ATF4 could restore autophagy in DN mice. Similar results were shown in vitro. Overexpression of ATF4 in NRK-52E cells cultured in high glucose condition suppressed autophagy and upregulated Collagen type 4 (Col-IV) expression, while inhibition of ATF4 could increase the number of the autophagosomes, improve autophagic flux and decrease Col-IV level. SIGNIFICANCE: Our study provided the evidence of a crucial role for ATF4 in inhibiting autophagy against diabetic kidney damage. Suppression of ATF4 may be an effective therapy in restraining renal tubulointerstitial fibrosis in DN.

Activating transcription factor 4 (ATF4), which regulates genes associated with endoplasmic reticulum stress, apoptosis, autophagy, the gut microbiome, and metabolism, has been implicated in many diseases. However, its mechanistic role in hypertension remains unclear. In the present study, we investigated its role in salt-sensitive hypertensive mice. Wild-type (WT) C57BL/6J mice were used to establish Atf4 knockout (KO) and overexpression mice using CRISPR-Cas9 and lentiviral overexpression vectors. Then, fecal microbiota transplantation (FMT) from Atf4 ± mice and vitamin K2 (VK2) supplementation were separately carried out in high-salt-diet (8% NaCl)-induced mice for 4 weeks. We found that Atf4 KO inhibited and Atf4 overexpression enhanced the increase in blood pressure and endothelial dysfunction induced by high salt intake in mice, while regulating the gut microbiota composition and VK2 expression. It was further verified that ATF4 is involved in the regulation of salt-sensitive hypertension and vascular endothelial function, which is achieved through association with gut microbiota and may be related to VK2 and different bacteria such as Dubosiella. In addition, we found that VK2 supplementation prevents the development of salt-sensitive hypertension and maintains vascular endothelial function; moreover, VK2 supplementation increases the abundance of intestinal Dubosiella and downregulates the relative expression of Atf4 in the thoracic aorta of mice. We conclude that ATF4 plays an important role in regulating gut microbiota and VK2 production, providing new insights into the association between ATF4 and development of salt-induced hypertension in mice, meanwhile contributing to the development for a new preventive strategy of hypertension.
RESUMEN
Resveratrol is one of the most well-known drugs used in the treatment of aging. However, the potential mechanisms of resveratrol on intestinal aging have not yet been fully investigated. Herein, we aimed to further explore the pharmacological mechanisms of resveratrol as a therapy for intestinal aging. We performed network construction and enrichment analysis via network pharmacology. Then a further animal experimental validation containing 20 female C57BL/6J (wild type, WT) and 16 female ATF4+/- (knock down, KD) naturally aging mice and oral supplementary resveratrol (44 mg/kg/day) for 30 days were conducted. The expression of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), linear alkylethoxylate (AE), and malondialdehyde (MDA) were measured by ELISA, the observation of pathological changes and apoptosis in intestinal tissue were performed by HE, PAS, and TUNEL staining, the ATF4/Chop/Bcl-2/Bax signaling pathway-related proteins and mRNAs expression were measured by western blotting and real-time PCR. The network pharmacology showed 132 targets of resveratrol on aging. The enrichment analysis showed resveratrol antiaging involved mainly included protein heterodimerization activity, apoptosis, etc. Then ATF4/Chop/Bcl-2/Bax signaling pathway in biological process of apoptosis was selected to verify the potential mechanisms. Animal studies showed resveratrol upregulated the relative expression of SOD, GSH-Px, CAT, AE, whereas it downregulated the relative expression of MDA in intestine compared with the control group. There was also higher relative expression of SOD, GSH-Px, CAT, AE, and lower relative expression of MDA in KD mice than that in WT mice. Moreover, there was higher relative expression of SOD, GSH-Px, CAT, AE, and lower relative expression of MDA in KD mice than that in WT mice after resveratrol treatment. Decreased ATF4, Chop, Bax but increased Bcl-2 proteins and mRNAs expression were determined after resveratrol treatment compared with the control group; lower ATF4, Chop, Bax but higher Bcl-2 proteins and mRNAs expression were found in KD mice than that in WT mice. Additionally, lower relative proteins and mRNAs expression of ATF4, Chop, Bax and higher relative expression of Bcl-2 in KD mice than that in WT mice after resveratrol treatment. These findings demonstrated that resveratrol substantially inhibited intestinal aging via downregulating ATF4/Chop/Bcl-2/Bax signaling pathway.
RESUMEN
OBJECTIVE: Gestational diabetes mellitus (GDM) is a pathological condition, affecting an increasing number of pregnant women worldwide. Safe and effective treatment for GDM is very important for the public health. In this study, we utilized a high-fat diet-induced GDM model to evaluate the effects of LBP on GDM and examined the changes of exosomal microRNA expression profiling to decipher the potential underlying mechanism of LBP. METHODS: Female C57BL/6J mice were fed a control diet, HFD, or 150 mg/kg LBP-supplemented HFD for 6 weeks before conception and throughout gestation. Oral glucose tolerance test and plasma lipid levels were determined, and liver histopathology was assessed. Sequencing was used to define the microRNA expression profiling of plasma exosomes in the three groups of mice, and protein expression levels of the candidate target genes were analyzed. RESULTS: LBP significantly relieved glucose intolerance, abnormal plasma lipid levels, and pathomorphological changes of liver histopathology in HFD-induced GDM mice. Moreover, we found that this effect of LBP was mediated by downregulation of the increase of 6 miRNAs (miR-93-3p, miR-188-5p, miR-466k, miR-1188-5p, miR-7001-3p, and miR-7115-5p) and reversing the increase of the protein expression of CPT1A, which is the target gene of miR-188-5p. CONCLUSIONS: Our findings provide novel insights into the biological activities of LBP in the treatment of GDM.
RESUMEN
OBJECTIVE: Naoxintong capsule (NXT) has been widely used to treat patients with cerebral infarction and carotid atherosclerosis. However, it is uncertain whether there is robust evidence on the effects of NXT for cerebral infarction and carotid atherosclerosis. A systematic review and meta-analysis of randomized trials were performed to assess the efficacy of NXT in the treatment of cerebral infarction and carotid atherosclerosis. METHODS: The Cochrane Library, EMBASE, the Medline database, the Wanfang database, the China National Knowledge Infrastructure, and the VIP database were searched up to January 2018 with no language restrictions. Study selection, data extraction, quality assessment, and data analyses were performed according to the Cochrane standards. RESULTS: Eleven studies (N=1141) in total satisfied the inclusion criteria for the meta-analysis. The results of meta-analysis showed that compared with the conventional therapy alone, NXT combined with conventional therapy could significantly improve national institutes of health stroke scale (NIHSS) score (MD= -3.92, 95%CI: -4.31~-3.52, P<0.00001), plaque area (MD= -0.16, 95%CI: -0.20~-0.13, P<0.00001), carotid intima-media thickness (IMT) (MD= -0.23, 95%CI: -0.26~-0.20, P<0.00001), total cholesterol (TC) (MD= -0.16, 95%CI: -0.79~-0.42, P<0.00001), triglyceride (TG) (MD= -0.69, 95%CI: -0.88~-0.51, P<0.00001), high-density lipoprotein cholesterol (HDL-C) (MD= 0.23, 95%CI: 0.15~0.31, P<0.00001), and low-density lipoprotein cholesterol (LDL-C) (MD= -0.42, 95%CI: -0.58~-0.25, P<0.00001). There were no reported adverse events in the studies. CONCLUSIONS: NXT is an effective and safe therapy option for patients with cerebral infarction and carotid atherosclerosis. However, due to the high clinical heterogeneity and small sample size of the included trials, further standardized preparation, large-scale and rigorously designed trials are needed.
RESUMEN
OBJECTIVES: To evaluate the efficacy and safety of Aidi injection (ADI) combined with transcatheter arterial chemoembolization (TACE) for primary hepatic carcinoma (PHCC). METHODS: We conducted a literature search in EMBASE, PubMed, CENTRAL, MEDLINE, CNKI, Wanfang, and VIP databases from the earliest possible year to April 2018. Randomized controlled trials (RCTs) involving ADI combined with TACE versus TACE alone for patients with PHCC were included. The Cochrane Risk of Bias tool was applied for quality assessment. RESULTS: 22 studies involving 1611 participants were included. The clinical response rate (RR = 1.28, 95% CI: 1.17-1.40; P < 0.00001), KPS score (RR = 1.78, 95% CI: 1.59-2.00; P < 0.00001), survival rate (RR = 1.27, 95% CI: 1.16-1.39; P < 0.00001), immune function (MD = 1.24, 95% CI: 0.98-1.51; P < 0.00001), and adverse effects (RR = 0.62, 95% CI: 0.57-0.68; P < 0.00001) of ADI plus TACE showed significant difference when compared with TACE alone. CONCLUSIONS: ADI combined with TACE in the treatment of PHCC improved the clinical response rate and safety compared to TACE alone. However, due to poor methodological quality of many of the included RCTs, more rigorously designed and large-scale RCTs are warranted to examine this beneficial effect in the future.
RESUMEN
BACKGROUND: Accumulating evidence suggests that early menarche is associated with adult obesity, which in turn may increase the risk of insulin resistance and hyperglycemia. However, the relation of menarcheal age with gestational diabetes mellitus (GDM) remains inconsistent across studies. The objective of this meta-analysis was to evaluate the association between age at menarche and GDM risk. MATERIALS AND METHODS: We searched Medline (PubMed), Embase, Web of Knowledge and the Cochrane library through the end of May 2017. We pooled summary relative risks (RR) with 95% confidence intervals (CIs). Stata 12.0 software was used to analyse the data. RESULTS: Five prospective studies were eligible for inclusion. The results of meta-analysis showed that women in the early menarcheal age group (at < 12 years of age) had a higher risk of GDM compared with those in the "not early" menarcheal age group (at ≥ 13 years of age) (pooled RR = 1.31, 95% CI: 1.05, 1.56) with moderate heterogeneity (I2 = 47.5%, P = 0.107). However, there was no obvious protection of late menarche (at ≥ 15 years of age) versus median menarche (at 13 years of age) (pooled RR = 1.12, 95% CI: 0.92, 1.32; I2 = 0%). CONCLUSIONS: The findings support an association between earlier age at menarche and increased risk of GDM. Age at menarche may help identify women with increased risk of developing GDM. However, considering the potential limitations in this study, further larger prospective studies are warranted to verify our findings.
RESUMEN
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). The aim of the present study was to screen out the potential candidate microRNAs (miRNAs) in DM patients with BSS by high-throughput sequencing (HTS) and bioinformatics analysis. 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 miRNAs (DE-miRNAs) were screened between samples and compared with known changes in mRNA abundance. Target genes of miRNAs were predicted by softwares. Gene Ontology (GO) and pathway enrichment analysis of the target genes were conducted. According to the significantly enriched GO annotations and pathways (P-value ≤ 0.001), we selected the key miRNAs of DM with BSS. It showed that the number of DE-miRNAs in BSS was 32 compared with non-blood stasis syndrome (NBS) and NC. The potential candidate miRNAs were chosen from GO annotations in which target genes were significantly enriched (-log10 (P-value) > 5), which included miR-140-5p, miR-210, miR-362-5p, miR-590-3p, and miR-671-3p. The present study screened out the potential candidate miRNAs in DM patients with BSS by HTS and bioinformatics analysis. The miRNAs will be helpful to provide valuable suggestions on clinical studies of DM with BSS at the gene level.
