Kidney-Targeted Drug Delivery System Based on Metformin-Grafted Chitosan for Renal Fibrosis Therapy.

Our previous study demonstrated that metformin plays an anti-fibrotic role in addition to its hypoglycemic effect. Worryingly, it often requires more than 5 times the hypoglycemic dose to achieve a satisfactory anti-fibrotic effect, which greatly increases the risk of systemic acidosis caused by metformin overdose. Low-molecular-weight chitosan (LMWC) has natural kidney-targeting properties and good biocompatibility and degradability.

Uterine Ultrasound Doppler Hemodynamics of Magnesium Sulfate Combined with Labetalol in the Treatment of Pregnancy-Induced Hypertension Using Empirical Wavelet Transform Algorithm.

The aim of this study was to explore the hemodynamic changes of magnesium sulfate combined with labetalol in the treatment of pregnancy-induced hypertension (PIH) under Doppler uterine ultrasound based on the empirical wavelet transform (EWT) algorithm. 500 patients with PIH in the hospital were selected and randomly divided into the control group ( = 250) and the observation group ( = 250). The control group was treated with conventional magnesium sulfate; the observation group was given labetalol based on magnesium sulfate drip in the control group.

Metformin attenuates renal tubulointerstitial fibrosis via upgrading autophagy in the early stage of diabetic nephropathy.

This study aimed at comparing the effects of metformin on tubulointerstitial fibrosis (TIF) in different stages of diabetic nephropathy (DN) in vivo and evaluating the mechanism in high glucose (HG)-treated renal tubular epithelial cells (RTECs) in vitro. Sprague-Dawley (SD) rats were used to establish a model of DN, and the changes of biochemical indicators and body weight were measured. The degree of renal fibrosis was quantified using histological analysis, immunohistochemistry, and immunoblot.

In vivo synergistic antitumor effect and safety of siRNA and lonidamine dual-loaded hierarchical targeted nanoparticles.

Based on development of nano-delivery system, co-delivery of chemotherapeutic drug and small interfering RNA (siRNA) has exerted a promising advantage in cancer therapy. In this work, the superiority of synergistic therapy and safety of the hierarchical targeted co-delivery system loaded with siRNA and lonidamine (LND) were evaluated. The in vivo tumor accumulation ability and cancer growth inhibition effect of the polymer-blend nanocarriers were evaluated by a H22 subcutaneous sarcoma model.

2-Deoxyglucose Reverses the Promoting Effect of Insulin on Colorectal Cancer Cells In Vitro.

An increased risk of colorectal cancer is related to the development of metabolic syndromes including hyperglycemia, and hyperinsulinemia. The high circulatory levels of glucose and/or insulin or the application of exogenous insulin may promote carcinogenesis, cancer progression and metastasis, which can be attributed to the Warburg effect or aerobic glycolysis. We attempted to resolve these existing questions by applying the glucose analog 2-deoxyglucose (2DG).

Codelivery of Doxorubicin and shAkt1 by Poly(ethylenimine)-Glycyrrhetinic Acid Nanoparticles To Induce Autophagy-Mediated Liver Cancer Combination Therapy.

Combination therapy has been developed as a promising therapeutic approach for hepatocellular carcinoma therapy. Here we report a low toxicity and high performance nanoparticle system that was self-assembled from a poly(ethylenimine)-glycyrrhetinic acid (PEI-GA) amphiphilic copolymer as a versatile gene/drug dual delivery nanoplatform. PEI-GA was synthesized by chemical conjugation of hydrophobic GA moieties to the hydrophilic PEI backbone via an acylation reaction.

Biocompatible polymeric nanocomplexes as an intracellular stimuli-sensitive prodrug for type-2 diabetes combination therapy.

Combination therapy is usually considered as a promising strategy owing to its advantages such as reduced doses, minimized side effects and improved therapeutic efficiency in a variety of diseases including diabetes. Here we synthesized a new highly intracellular stimuli-sensitive chitosan-graft-metformin (CS-MET) prodrug by imine reaction between oxidative chitosan and metformin for type 2 diabetes (T2D) therapy. Hypothetically, CS-MET functions dually as an anti-diabetes prodrug as well as a gene delivery vector without superfluous materials.
