Construction and evaluation of liposomal drug delivery system for an ALK/HDACs dual-targeted inhibitor with sustained release and enhanced antitumor effect.

ALK/HDACs dual target inhibitor (PT-54) was a 2,4-pyrimidinediamine derivative synthesized based on the pharmacophore merged strategy that inhibits both anaplastic lymphoma kinase (ALK) and histone deacetylases (HDACs), which has demonstrated significant efficacy in treating multiple cancers. However, its poor solubility in water limited its clinical application. In this study, we prepared PT-54 liposomes (PT-54-LPs) by the membrane hydration method to overcome this defect.

The Effect of Coenzyme Q10 Supplementation on Bile Acid Metabolism: Insights from Network Pharmacology, Molecular Docking, and Experimental Validation.

Scope: Bile acids play a crucial role in lipid absorption and the regulation of lipid, glucose, and energy homeostasis. Coenzyme Q10 (CoQ10), a lipophilic antioxidant, has been recognized for its positive effects on obesity and related glycolipid metabolic disorders. However, the relationship between CoQ10 and bile acids has not yet been evaluated.

Construction and evaluation of a phospholipid-based phase transition in situ gel system for brexpiprazole.

The objective of this study was to develop phospholipid-based injectable phase transition in situ gels (PTIGs) for the sustained release of Brexpiprazole (Brex). Phospholipid (Lipoid S100, S100) and stearic acid (SA) were used as the gel matrix which was dissolved in biocompatible solvent medium-chain triglyceride (MCT), N-methyl pyrrolidone (NMP), and ethanol to obtain PTIGs solution. The Brex PTIG showed a solution condition of low viscosity in vitro and was gelatinized in situ in vivo after subcutaneous injection.

Preparation and characterization of a gemini surfactant-based biomimetic complex for gene delivery.

Gemini surfactants (GS) have been explored as non-viral gene delivery systems. Nevertheless, their cytotoxicity and the limitations in the in vivo studies have impeded their development. To attenuate toxicity and further explore their possibilities in gene delivery, a series of GS (18-7-18)-based gene delivery systems complexed with red blood cell membranes (RBCM) or/and DOPE-PEG (DP) were prepared and evaluated.

MiR-190b impedes pancreatic β cell proliferation and insulin secretion by targeting NKX6-1 and may associate to gestational diabetes mellitus.

Background: The dysfunction of pancreatic β cells is related to the occurrence of gestational diabetes mellitus (GDM). This study aimed to investigate the mechanism underlying the effects of miR-190b on pancreatic β cell proliferation and insulin secretion.

Methods: Quantitative real-time PCR was used to detect miR-190b expression in placenta tissues from GDM patients.

[Clinical study of Jiawei Bazhen decoction combined with oxytocin for cervical ripening of qi and blood deficiency type of pregnant women].

To study preliminarily the effect of Jiawei Bazhen decoction combined with oxytocin in promoting cervical ripening of full-term pregnancy women who were in the deficiency of qi and blood type through the syndrome differentiation of traditional Chinese medicine (TCM). 180 patients that met the inclusion criteria of the study were randomly divided into three groups: the control group(oxytocin group), the treatment group (Jiawei Bazhen decoction combined with oxytocin group), the blank control group (expected and observation group). Cervical maturity score (Bishop score), vaginal and cervical secretions fetal fibronectin (FFN), the result of induced labor, the result of mother and baby were observed in each group before and after treatment.

[Determination of germanium in aloe vera by spectrophotometric method].

Objective: To analyze the organic germanium in aloe vera from different localities.

Methods: The method was based on germanium forms a stable complex with phenylfluorone in the acidified solution and CTMAB as solubilization agent. The contents of the organic germanium in Aloe vera from different localities were determined by spectrophotometric methods.
