Measurement of enzyme activity of insoluble substrates based on ordered porous layer interferometry and the application in evaluation of thrombolytic drugs.

The development of innovative methods for real-time surveillance of enzymatic activity determination processes is essential, particularly for insoluble substrate enzymatic assessments. In this work, a novel method for enzymatic activity determination was devised by assembling a 190 nm silica colloidal crystal (SCC) film onto a glass slide, coupled with Ordered Porous Layer Interferometry (OPLI) technology. By fixing the substrate of the enzyme on the surface of the silica sphere, a solid-liquid interface can be formed for monitoring enzymatic activity.

The Jiangtang Tongmai Prescription Inhibits Inflammation and Fibrosis of Lung Fibroblast Autophagy Induced by Hyperglycemia by Regulating CAV1 Expression.

Objective: The lung is one of the target organs of diabetes. This study aimed to probe the protective mechanism of Jiangtang Tongmai Prescription (JTTMP) against diabetic lung injury.

Methods: JTTMP-containing serum was collected, and a high glucose and high-fat diabetic cell model was established.

Liraglutide Accelerates Ischemia-Induced Angiogenesis in a Murine Diabetic Model.

Background Severe hindlimb ischemia is a chronic disease with poor prognosis that can lead to amputation or even death. This study aimed to assess the therapeutic effect of liraglutide on hind-limb ischemia in type 2 diabetic mice and to elucidate the underlying mechanism. Methods and Results Blood flow reperfusion and capillary densities after treatment with liraglutide or vehicle were evaluated in a mouse model of lower-limb ischemia in a normal background or a background of streptozotocin-induced diabetes.

Jiangtang Tongmai Prescription Reduced Diabetic Lung Injury Through SnoN and TGF-β1/Smads Signaling Pathway.

By establishing a rat diabetes model in rats with intervening treatment by Jiangtang Tongmai Prescription (JTTMP), this study explored the restorative pairing effect of JTTMP on diabetic lung injury. The model of type II diabetes model was used to establish the rat diabetes model, using a high-fat diet and streptozotocin (STZ) induction. Different doses of JTTMP and metformin were administered as a therapeutic to intervene, and blood was collected to assess the blood glucose level of each group of rats.

Transcriptome Analysis of Traditional Chinese Medicine 'Kechuanning Plaster' in the Treatment of Asthma.

Background: Asthma is a severe chronic inflammatory airway disease. Kechuanning plaster has excellent efficacy in the treatment of asthma.

Objective: The aim of this study was to analyze the molecular mechanisms of Kechuanning plaster in the treatment of asthma.

Secreted frizzled-related protein 5 promotes angiogenesis of human umbilical vein endothelial cells and alleviates myocardial injury in diabetic mice with myocardial infarction by inhibiting Wnt5a/JNK signaling.

The purpose of this study is to investigate whether secreted frizzled-related protein 5 (SFRP5) affects the proliferation, migration and angiogenesis of human umbilical vein endothelial cells (HUVECs) induced by high glucose (HG). HUVECs were treated with different concentrations of glucose. MTT, wound healing, angiogenesis, and ELISA assays were used to detect cell cytotoxicity, migration, tube formation, and VEGF165 and VEGF165b levels, respectively.
