Danggui Liuhuang Decoction ameliorates endothelial dysfunction by inhibiting the JAK2/STAT3 mediated inflammation.

Ethnopharmacological Relevance: Vascular endothelial dysfunction (VED) is recognized as a key triggering diabetic vascular complications. Danggui Liuhuang Decoction (DGLHD) has shown potential in mitigating these complications. However, the clinical efficacy of DGLHD in enhancing endothelial function, as well as the molecular mechanisms underlying its alleviation of Type 2 Diabetes-Related Vascular Endothelial Dysfunction (T2DM-VED), remains insufficiently understood.

Association of Monocyte-to-HDL Cholesterol Ratio with Endothelial Dysfunction in Patients with Type 2 Diabetes.

Aims: To explore the relationship between monocyte-to-HDL cholesterol ratio (MHR) and endothelial function in patients with type 2 diabetes (T2DM).

Methods: 243 patients diagnosed with T2DM were enrolled in this cross-sectional study. Patients were divided into two groups by flow-mediated dilation (FMD) quintile as nonendothelial dysfunction (FMD ≥ 6.

Reduced Branched-Chain Amino Acid Intake Improved High-Fat Diet-Induced Nonalcoholic Fatty Pancreas Disease in Mice.

Objective: To explore the effects of branched-chain amino acids (BCAAs) on nonalcoholic fatty pancreas disease (NAFPD) and its possible mechanism in high-fat diet (HFD) induced mice.

Materials And Methods: Pancreatic morphology and lipid infiltration was assessed by hematoxylin-eosin staining and immunohistochemistry, and lipid levels in the pancreas were determined using colorimetric enzymatic method. Relevant mechanism was investigated using western blotting and biochemical test.

Tyrosol attenuates lipopolysaccharide‑induced inflammation in HUVECs to promote vascular health against atherosclerosis challenge.

The role of vascular endothelial cells in acute and chronic vascular inflammatory response has long been recognized. Therefore, persistent vascular inflammation may lead to endothelial dysfunction, thus resulting in the release of pro-inflammatory cytokines and the expression of adhesion molecules, which in turn promote monocyte/macrophage adhesion. Inflammation serves a key role in the development of vascular diseases, such as atherosclerosis.

Astragalus polysaccharide ameliorates vascular endothelial dysfunction by stimulating macrophage M2 polarization via potentiating Nrf2/HO-1 signaling pathway.

Background: Oxidative stress and chronic non-infectious inflammation caused vascular endothelial dysfunction (VED) is a critical and initiating factor in Type 2 diabetes induced vascular complications, while macrophage polarization plays a regulatory role in VED. Astragalus polysaccharide (APS) has been widely used for treating diabetic vascular diseases, but its mechanisms of action have not been fully elucidated.

Purpose: This study aimed to investigate the modulatory effects of APS on macrophage polarization and to reveal the potential mechanisms of APS in LPS and HG stimulated macrophages and diabetic model rats.

Berberine inhibits gluconeogenesis in spontaneous diabetic rats by regulating the AKT/MAPK/NO/cGMP/PKG signaling pathway.

This work was aimed to investigate the action mechanism of berberine (BBR) on gluconeogenesis. The effects of BBR were examined in rat primary hepatocytes and confirmed in vivo in spontaneous diabetic rats. Protein levels were assessed by Western blot.

Relationship between the neutrophil to high-density lipoprotein cholesterol ratio and severity of coronary artery disease in patients with stable coronary artery disease.

Objective: To evaluate the link between the neutrophil to HDL-C ratio (NHR) and the degree of coronary stenosis in patients with stable coronary artery disease (CAD).

Materials And Methods: Totally 766 individuals who attended our clinic for coronary angiography between January 2019 and January 2021 were included in this study. The participants were divided into two groups, including the CAD group and control group.

Efficacy and Safety of Wuling Powder in the Treatment of Patients with Diabetic Nephropathy: A Systematic Review and Meta-Analysis.

Background: Wuling powder is a classical formula of traditional Chinese medicine (TCM), which is extensively applied to treat diabetic nephropathy (DN). However, there are no related reports on systematically evaluating the efficacy of Wuling powder in the treatment of DN. Targeted at this, this study was developed.

Resveratrol ameliorated endothelial injury of thoracic aorta in diabetic mice and Gly-LDL-induced HUVECs through inhibiting TLR4/HIF-1α.

To explore the effects of resveratrol on the levels of inflammatory cytokines and Toll-like receptor-4/ hypoxia-inducible transcription factors-1α (TLR4/HIF-1α) signalling pathway in diabetes mellitus. C57BL/6 mice received intraperitoneal injection of streptozocin for constructing diabetic mice models. Human umbilical vein endothelial cells (HUVECs) were treated with 50 µg/mL Gly-LDL for inducing injury models.

Resveratrol improves Gly-LDL-induced vascular endothelial cell apoptosis, inflammatory factor secretion and oxidative stress by regulating miR-142-3p and regulating SPRED2-mediated autophagy.

Background: Resveratrol improves cell apoptosis and tissue damage induced by high glucose, but the specific mechanism is unknown.

Methods: This is a basic research. We performed cell transfection, real-time fluorescence quantitative PCR (qPCR), flow cytometry, immunofluorescence, western blot, enzyme linked immunosorbent assay (ELISA) and cell viability assay to analyze cell viability, cell cycle, cellular oxidative stress, intracellular inflammatory factors and autophagy activities .

The Role of SGLT2 Inhibitor on the Treatment of Diabetic Retinopathy.

Diabetic retinopathy (DR) is one of the most serious complications of diabetic microangiopathy. DR has an early onset and is not easy to detect. When visual impairment occurs, the optimal period for therapy is often missed.

Glial cell line-derived neurotrophic factor (GDNF) mediates hepatic stellate cell activation via ALK5/Smad signalling.

Objective: Although glial cell line-derived neurotrophic factor (GDNF) is a member of the transforming growth factor-β superfamily, its function in liver fibrosis has rarely been studied. Here, we investigated the role of GDNF in hepatic stellate cell (HSC) activation and liver fibrosis in humans and mice.

Design: GDNF expression was examined in liver biopsies and sera from patients with liver fibrosis.

The role of central nervous system on hypoglycemia and the feasibility of the brain theory in traditional Chinese medicine on treatment of diabetes mellitus.

The central nervous system (CNS) plays a key regulatory role in glucose homeostasis. In particular, the brain is important in initiating and coordinating protective counterregulatory responses when blood glucose levels fall. This may due to the metabolic dependency of the CNS on glucose, and protection of food supply to the brain.
