Shuanglongjiegu pill promoted bone marrow mesenchymal stem cell osteogenic differentiation by regulating the miR-217/RUNX2 axis to activate Wnt/β-catenin pathway.

This study aimed to investigate the effects of Shuanglongjiegu pill (SLJGP) on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and explore its mechanism based on miR-217/RUNX2 axis. Results found that drug-containing serum of SLJGP promoted BMSCs viability with a dose-dependent effect. Under osteogenic differentiation conditions, SLJGP promoted the expression of ALP, OPN, BMP2, RUNX2, and the osteogenic differentiation ability of BMSCs.

Scutellarin regulates osteoarthritis by inhibiting the PI3K/AKT/mTOR signaling pathway.

Osteoarthritis (OA) is a highly prevalent disease worldwide that causes disability and diminishes the quality of life of affected individuals. The disease is characterized by cartilage destruction, increased inflammatory responses and cholesterol metabolic disorder. Scutellarin is the major active ingredient extracted from , and it has been demonstrated to possess various pharmacological functions in the treatment of the disease.

[Effect of Baihu Guizhi decoction on characteristic methylation genes expression of pyretic arthralgia rat model].

To investigate the characteristic methylation genes of pyretic arthralgia model in hot and dampness environment and the regulation effect of Baihu Guizhi decoction on this characteristic methylation genes. Plantar injection of CFA was used in hot and dampness environment to induce the pyretic arthralgia rat models. From 15th day after modeling, Baihu Guizhi decoction was given for 30 days.

[Effect of Tongluo Xingnao effervescent tablets on learning and memory dysfunction in rats with chronic cerebral ischemia].

Objective: To study the effect of Tongluo Xingnao effervescent tablets on learning and memory capacity and expression of Na(+)-K(+)-ATPase in hippocampus of rats with chronic cerebral ischemia-induced learning and memory dysfunction model.

Method: The 2-VO method was used to establish sd rat model learning and memory dysfunction induced by chronic cerebral ischemia. The 50 rats in the successfully established model were randomly divided into the model control group, the Dihydroergotoxine Mesylate tablets group (0.

[Fluorescence studies of Eu ions adsorption on pseudo-boehmite colloidal particle surface].

Stable pseudo-boehmite sol was obtained by adding HNO3 as peptizing agent and adjusting pH to be 2.0. TEM result shows that the AlOOH colloidal particle size is about 60 nm.
