Abstract
Diabetic foot ulcer (DFU) is a leading cause of high-level amputation in DM patients, with a low wound healing rate and a high incidence of infection. Vascular endothelial growth factor (VEGF) plays an important role in diabetes mellitus (DM) related complications. This study aims to explore the VEGF expression and its predictive value for prognosis in DFU, in order to provide basis for the prevention of DFU related adverse events. We analyzed 502 patients, with 328 in healing group and 174 in non-healing/recurrent group. The general clinical data and laboratory indicators of patients were compared through Spearman correlation analysis, ROC analysis and logistic regression analysis. Finally, the independent risk factors for adverse prognosis in DFU patients were confirmed. Spearman analysis reveals a positive correlation between the DFU healing rate and ABI, VEGF in wound tissue, and positive rate of VEGF expression, and a negative correlation with DM duration, FPG, HbA1c, TC, Scr, BUN, and serum VEGF. Further logistic regression analysis finds that the DM duration, FPG, HbA1c, ABI, serum VEGF, VEGF in wound tissue, and positive rate of VEGF expression are the independent risk factors for adverse prognosis in DFU (p < 0.05). DM duration, FPG, HbA1c, ABI, serum VEGF, VEGF in wound tissue, and positive rate of VEGF expression are the independent risk factors for prognosis in DFU patients. Patients with these risk factors should be screened in time, which is of great significance to prevent DFU related adverse events and improve outcomes.

Metabolic memory in diabetic foot syndrome (DFS): MICRO-RNAS, single nucleotide polymorphisms (SNPs) frequency and their relationship with indices of endothelial function and adipo-inflammatory dysfunction. Cardiovasc Diabetol 2023; 22:148. [PMID: 37365645 DOI: 10.1186/s12933-023-01880-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 06/06/2023] [Indexed: 06/28/2023] Open
Abstract
BACKGROUND Diabetic foot is a significant cause of morbidity in diabetic patients, with a rate that is approximately twice that of patients without foot ulcers. "Metabolic memory" represents the epigenetic changes induced by chronic hyperglycaemia, despite the correction of the glucose levels themselves. These epigenetic modifications appear to perpetuate the damage caused by persistently elevated glucose levels even in their absence, acting at various levels, mostly affecting the molecular processes of diabetic ulcer healing. METHODS The aim of our cross-sectional study was to analyse a cohort of patients with diabetes with and without lower limb ulcers. We examined the effects of epigenetic changes on miRNA 126, 305, and 217 expression and the frequency of the SNPs of genes encoding inflammatory molecules (e.g., IL-6 and TNF-alpha) and their correlations with serum levels of proangiogenic molecules (e.g., ENOS, VEGF and HIF-1alpha) and several adipokines as well as with endothelial dysfunction, assessed noninvasively by reactive hyperaemia peripheral artery tonometry. Between March 2021 and June 2022, 110 patients were enrolled into the study: 50 diabetic patients with diabetic foot injuries, 40 diabetic patients without ulcerative complications and 20 nondiabetic patients as the control group. RESULTS Diabetic subjects with lower limb ulcerative lesions exhibited higher levels of inflammatory cytokines, such as VEGF (191.40 ± 200 pg/mL vs. 98.27 ± 56.92 pg/mL vs. 71.01 ± 52.96 pg/mL; p = 0.22), HIF-1alpha (40.18 ± 10.80 ng/mL vs. 33.50 ± 6.16 ng/mL vs. 33.85 ± 6.84 ng/mL; p = 0.10), and Gremlin-1 (1.72 ± 0.512 ng/mL vs. 1.31 ± 0.21 ng/mL vs. 1.11 ± 0.19 ng/mL; p < 0.0005), than those without lower limb ulcers and healthy controls. Furthermore, we observed that miR-217-5p and miR-503-5p were 2.19-fold (p < 0.05) and 6.21-fold (p = 0.001) more highly expressed in diabetic foot patients than in healthy controls, respectively. Additionally, diabetic patients without lower limb ulcerative complications showed 2.41-fold (p = 0) and 2.24-fold (p = 0.029) higher expression of miR-217-5p and miR-503-5p, respectively, than healthy controls. Finally, diabetic patients with and without ulcerative complications of the lower limbs showed higher expression of the VEGFC2578A CC polymorphism (p = 0.001) and lower expression of the VEGFC2578A AC polymorphism (p < 0.005) than the healthy control population. We observed a significant increase in Gremlin-1 levels in patients with diabetic foot, suggesting that this inflammatory adipokine may serve as a predictive marker for the diagnosis of diabetic foot. CONCLUSIONS Our results highlighted that patients with diabetic foot showed predominant expression of the VEGF C2578A CC polymorphism and reduced expression of the AC allele. Additionally, we found an overexpression of miR-217-5p and miR-503-5p in diabetic patients with and without diabetic foot syndrome compared with healthy controls. These results align with those reported in the literature, in which the overexpression of miR-217-5p and miR-503-5p in the context of diabetic foot is reported. The identification of these epigenetic modifications could therefore be helpful in the early diagnosis of diabetic foot and the treatment of risk factors. However, further studies are necessary to confirm this hypothesis.

Abstract
Diabetes mellitus has become a global health problem, and the number of patients with diabetic foot ulcers (DFU) is rapidly increasing. Currently, DFU still poses great challenges to physicians, as the treatment is complex, with high risks of infection, recurrence, limb amputation, and even death. Therefore, a comprehensive understanding of DFU pathogenesis is of great importance. In this review, we summarized recent findings regarding the DFU development from the perspective of single-nucleotide variations (SNVs). Studies have shown that SNVs located in the genes encoding C-reactive protein, interleukin-6, tumor necrosis factor-alpha, stromal cell-derived factor-1, vascular endothelial growth factor, nuclear factor erythroid-2-related factor 2, sirtuin 1, intercellular adhesion molecule 1, monocyte chemoattractant protein-1, endothelial nitric oxide synthase, heat shock protein 70, hypoxia inducible factor 1 alpha, lysyl oxidase, intelectin 1, mitogen-activated protein kinase 14, toll-like receptors, osteoprotegerin, vitamin D receptor, and fibrinogen may be associated with the development of DFU. However, considering the limitations of the present investigations, future multi-center studies with larger sample sizes, as well as in-depth mechanistic research are warranted.

Molecular mechanism of Chuanxiong Rhizoma in treating coronary artery diseases. CHINESE HERBAL MEDICINES 2021; 13:396-402.

Abstract
Objective Most of the studies on the herb Chuanxiong Rhizoma (CR) have focused on the l-arginine-nitric oxide (NO) pathway, but the nitrate-nitrite-NO (NO3−–NO2−–NO) pathway was rarely investigated. Therefore, the aim of this study was to evaluate the effects and mechanisms of action of CR in coronary artery disease (CAD). Methods The NO3−, NO2− and NO levels were examined in the NO3−–NO2−–NO pathway. High-performance ion chromatography was used to quantify NO3− and NO2− levels. Then, NO was quantified using a multifunctional enzyme marker with a fluorescent probe. The tension of aortic rings was measured using a multi myograph system. Results High content of NO3− and low content of NO2− was found in CR, and which could potently convert NO3− to NO2− in the presence of endogenous reductase enzyme. Incubating human coronary artery endothelial cells (HCAECs) with CR-containing serum showed that CR significantly decreased the NO3− content and increased the levels of NO2− and NO in the cells under hypoxic conditions. In addition, CR significantly relaxed isolated aortic rings when the l-arginine –NO pathway was blocked. The optimal concentration of CR for relaxation was 200 mg/mL. Conclusion CR supplements large amounts of NO in cells and vessels to achieve relaxation via the NO3−–NO2−–NO pathway, thereby making up for the deficiency caused by the lack of NO after the l-arginine-NO pathway is suppressed. This study also supports the potential use of a traditional Chinese herb for future drug development.

Abstract
OBJECTIVE This study aims to explore the relation between endothelial nitric oxide synthase (eNOS) single-nucleotide polymorphisms (SNPs) and the risk of coronary heart disease (CHD). METHODS SNPstats (online software: http://bioinfo.iconcologia.net/SNPstats) was performed to test Hardy-Weinberg equilibrium in controls. Generalized multifactor dimensionality reduction (GMDR) was adopted to screen the preferable interaction between eNOS SNPs and smoking. RESULTS The frequency for the rs1799983-T allele was 31.1% in CHD patients, which was significantly higher than that of 19.8% in controls (P < 0.05). The frequency for the rs891512-A allele was 28.8% in cases, which was also significantly higher than that of 20.1% in controls (P < 0.05). Logistic regression analysis showed that both rs1799983-T and rs891512-A alleles were related with increased risk of CHD, and the odds ratios (ORs) [95% confidence interval (CI)] were 1.71 (1.31-2.15) and 1.57 (1.14-2.07), respectively. High-order interactions were investigated among SNPs and environmental factors using the GMDR method. The data showed that a two-locus model (rs1799983 × smoking) had a testing accuracy of 0.60 (P = 0.001). We found that current smokers with rs1799983-GT or TT within eNOS gene have the highest CHD risk, compared to never smokers with rs1799983-GG genotype, OR (95% CI) = 2.74 (1.78-3.85), after covariates adjustment for age, gender, BMI, and alcohol drinking. CONCLUSION The rs1799983-T and rs891512-A alleles and interaction between rs1799983 and smoking were all risk factors of CHD.

Abstract
BACKGROUND Diabetic foot (DF) is a dangerous complication of diabetes. The aim of the study was to synthesize all the published single nucleotide polymorphisms (SNPs) of DF to objectively evaluate the relationship of SNPs and DF risks. METHODS The HuGE database and CNKI were searched for eligible publications on genetic polymorphisms and the risk of DF systematically. The quality of literatures was evaluated by the Newcastle-Ottawa scale. Pooled odds ratios with a 95% confidence interval for SNPs were evaluated through 3 genetic models. RESULTS Citing 29 different polymorphisms from 24 articles and the study met our selection criteria. There were 24 polymorphisms summarized systematically, and 5 merged polymorphisms for a meta-analysis: 9 positively associated with DF: HIF-1α rs11549465, TNF-α rs1800629, TLR-9 rs5743836, FIB rs6056, HSP70-2437C/T, VDR rs2228570, LOX rs1800449, ITLN1 rs2274907, and OPG rs2073617, but OPG rs3134069 was not a risk factor in DF; 6 negatively associated with DF: VEGF rs833061 and rs2010963, MCP-1 rs1024611, SDF-1 rs1801157, SIRT1 rs12778366, and OPG rs2073617. In addition, 13 polymorphisms were not associated with DF: MMP-9 rs3918242, eNOS rs1799983, VEGF rs3025039, -7C/T, rs1570360, rs13207351, and rs699947, IL-6 rs1800795, HIF-1α rs11549467, TNF-α rs361525, TLR-2 rs3804100, SIRT1 rs3758391, and TIMP-1 rs2070584. CONCLUSIONS The study provided some evidence for SNPs to the development of diabetic foot. The meta-analysis showed that rs1024611 of MCP-1 may be regarded as a protective factor, especially in Asian populations. Other loci indicated inconsistent results.

Abstract
To investigate the relationship between diabetic foot complications (DFCs) and clinical characteristics, especially the number and types of first-degree family members with diabetes. A total of 8909 type 2 diabetes patients were enrolled. The clinical characteristics of these patients, including DFCs and family history of diabetes (FHD), were collected from medical records. Multiple regression was used to investigate the association between FHD and DFCs after adjusting for confounding factors. The patients with one and more than one first-degree family member with diabetes accounted for 18.7% and 12.8%, respectively. The proportions of the participants with a father with diabetes, a mother with diabetes, both parents with diabetes, siblings with diabetes, father and siblings with diabetes, mother and siblings with diabetes, and both parents and siblings with diabetes were 3.5%, 6.2%, 1.1%, 14.4%, 1.5%, 4%, and 0.7%, respectively. The multiple regression analysis showed that the number of family members with diabetes was positively associated with DFCs. However, among the different types of FHD, only the patients with a mother with diabetes showed a statistical association with DFCs. In addition to FHD, other factors, including gender, body mass index, platelet count, hemoglobin levels, albumin levels, high-density cholesterol levels, diabetic peripheral neuropathy, and the use of lipid-lowering agents, oral hypoglycemic agents, and insulin, were also associated with DFCs. DFCs were associated with different numbers of family members with diabetes and types of FHD. This association reveals the importance of genetic and environmental factors in DFCs and highlights the importance of adding FHD to public health strategies targeting detecting and preventing the disease.

Abstract
AIM/HYPOTHESIS Diabetes is a hyperglycaemic disease treated by a set of allopathic drugs and natural biomolecules along with many variety of stem cell. We aim to investigate the role of these drugs in targeting common protein molecule in diabetes and its associated disease. We also aim to investigate the organ degeneration mechanistic pathway in diabetes. METHOD We have generated diabetes using streptozotocin injection and treated them using bone marrow transplantation and curcumin administration. The organs were studied histopathologically and by immunofluorescence analysis while drugs were studied Pharmacogenomically. RESULT Mice injected with streptozotocin have higher glucose and lower insulin, islet number/diameter, bone marrow cell number compared to control and bone marrow transplanted and curcumin administered mice. Histopathology staining demonstrates damaged morphology of pancreas, kidney, brain and cardiac muscle. Further, upon comparison of all allopathic and ayurvedic drugs used for diabetes several protein targets have been identified by reverse pharmacophore analysis using PharmMapper. VEGF, CDK2, insulin receptor, HSp90, eNOS, Fructose1,6 bisphosphatase, neprilysin, AchE, MAPK are several common protein targets of anti-diabetic drugs. CONCLUSION This article demonstrates that VEGF and CDK2 are critical marker in organ damage in diabetes as well as organ regeneration.

Abstract
As a flavonoid, naringin (Nar) has been shown to have multiple pharmacological effects including lowering blood cholesterol, reducing thrombus formation and improving microcirculation. However, effects of Nar on function and autophagy of vascular endothelial cells under high glucose and high fat (HG/HF) stress are largely unclear. This study was designed to investigate such effects of Nar in human umbilical vein endothelial cells (HUVECs) and to determine whether such effects are related to autophagy. Our present results show that 86 μM of Nar inhibits the autophagy levels and protects the cells against the dysfunction induced by HG/HF stress. Moreover, Nar increases the phosphorylation levels of phosphatidylinositol-3-kinase (PI3K), protein kinase B (Akt) and mammalian rapamycin target protein (mTOR). However, pretreatment with rapamycin (RAPA, 5 μM, autophagy inducer), LY294002(10 μM, PI3K inhibitor) and Akt inhibitor Ⅳ (0.5 μM, Akt inhibitor) partially abrogates the protective effects of Nar, suggesting that the protective effects of Nar are achieved by activating the PI3K-Akt-mTOR pathway to inhibit autophagy. In conclusion, Nar improves the function of HUVECs under HG/HF stress through activating the PI3K-Akt-mTOR pathway to inhibit autophagy. The findings offer an insight into HG/HF stress-induced autophagy and indicate that Nar might have potential to prevent and treat the diabetic angiopathy.
