Objective: To investigate the effect of tetrandrine (Tet) on the expression of bax, bcl-2, and transforming growth factor-β2 (TGF-β2) mRNA in cultured human fibroblasts of Tenon's capsules (TCFS) and explore its possible mechanism.
Methods: The third passage of TCFS cultured in vitro were exposed to 1×10(-5) mol/L Tet for 24 h, and real-time fluorescence quantitative PCR was used to detect the changes in the expressions of bax, bcl-2, and TGF-β2 mRNA.
Results: The expression level of bax mRNA was obviously higher, while bcl-2 and TGF-β2 mRNA levels were significantly lower in Tet-treated TCFS than those in the control cells (P<0.05).
Conclusion: Tet can inhibit the proliferation of TCFS possibly by reducing the expressions of bcl-2 and TGF-β2 mRNA, enhancing the expression of bax mRNA and inducing cell apoptosis, suggesting its potential in preventing fibrous scar formation after glaucoma filtration surgery.

Nephrotoxicity remains a significant concern associated with tyrosine kinase inhibitors, such as dasatinib (DASA). Previous studies have shown that DASA can induce renal tubular cell death, contributing to its nephrotoxic effects. In contrast, naringenin (NGN) is known for its antioxidant and anti-inflammatory properties.

Objective: To investigate the effects of Curcumol on the malignant biological characteristics of acute myeloid leukemia (AML) cells and its molecular mechanism, and to provide theoretical and experimental evidence for the anti-leukemia treatment of traditional Chinese medicine.
Methods: After the AML cell lines HL-60 and KG-1 cells were treated different concentrations of with Curcumol. The proliferation activity of cells was detected by CCK-8 method, and the expression changes of apoptotic proteins and PI3K/AKT signaling pathway proteins were detected by Western blot.

Background: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are significant burdens on global health. Remimazolam (REM), a novel sedative, has shown potential in its anti-inflammatory effects. However, a lack of evidence currently hinders our ability to determine if REM can improve ALI/ARDS.
