Objective: To investigate the effect of Kangquan Recipe (KQR) on apoptosis regulatory genes bax and bcl-2 mRNA in prostate of rats.
Methods: Benign prostatic hyperplasia model rat was established by injecting testosterone after castration. The model rats were killed and prostate glands were removed for examination after being treated with administration of KQR by gastrogavage for 30 days. The wet weight of prostate was measured and the mRNA expressions of bax and bcl-2 in rats' tissue of abdominal lobe of prostate were determined by RT-PCR.
Results: Compared with the model group, wet weight of prostate was lower significantly in the groups treated with different dosages of KQR (P < 0.05 or P < 0.01), and that in the high dose KQR treated group was similar to that in the normal group (P > 0.05). Compared with the model group, the expressions of bax mRNA and ratios of bax/bcl-2 were significantly higher and the expressions of bcl-2 mRNA significantly lower in the KQR treated groups (P < 0.01), and these indexes in the high dose KQR treated group were insignificantly different from those in the normal group (P > 0.05).
Conclusion: KQR shows an obvious treatment effect on rats with benign prostatic hyperplasia, the mechanism might be through effectively regulating the expressions of bax mRNA and bcl-2 mRNA in prostatic tissue to accelerate the cell apoptosis of prostate in obvious dose-effect manner.

The present study aimed to evaluate the impact of (NAC) on testicular hypoxia caused by varicocele, focusing specifically on the regulation of genes related to apoptosis and oxidative stress in the testes of mature Wistar rats. Thirty-two rats were divided into four groups: Control (Sham), hypoxia, testicular hypoxia treated with NAC (Hypoxia + NAC), and healthy animals treated with NAC. After the 8-week treatment period, testicular histopathology and the levels of oxidative stress markers-superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA)-in serum were examined.

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.

Cinnamaldehyde (CA), the primary bioactive compound in cinnamon ( Presl, Lauraceae, ), holds potential therapeutic benefits for Parkinson's disease (PD). To scrutinize the impact and mechanisms of CA on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD, male C57BL/6 mice were randomly allocated to CA (150, 300, and 600 mg/kg), model, Madopar, and control group ( = 12). The Open Field, Pole-jump, and Rotarod experiments assessed exercise capacity and anxiety levels.
