[Effect of puerarin on PI3K/AKT pathway-mediated apoptosis of PASMCs].

To discuss the effect of puerarin (Pue) on the proliferation of hypoxia-induced pulmonary artery smooth muscle cells (PASMCs) and discuss whether the extracellular signal PI3K/AKT pathway was involved in the Pue-induced PASMC apoptosis. With the serum starvation group (SD group) as the control group, the MTT colorimetry method, Annexin V-FITC apoptosis detection kit and Western blot were used to detect Pue's effect on apoptosis of rat PASMCs. The protein immunoblot assay was used to detect whether PI3K/AKT pathway was involved in the inhibition of hypoxia-induced PASMC apoptosis process.

[Effect of puerarin on hypoxia induced proliferation of PASMCs by regulating reactive oxygen].

To discuss the effect of puerarin (Pue) on the proliferation of hypoxia-induced pulmonary artery smooth muscle cells (PASMCs) and discuss whether its mechanism is achieved by regulating reactive oxygen. PASMCs of primarily cultured rats (2-5 generations) were selected in the experiment. MTT, Western blot, FCM and DCFH-DA were used to observe Pue's effect the proliferation of PASMCs.

Correlations Among Serum Hepatitis B Surface Antigen and Hepatitis B e Antigen Titers and Viral Load in Chinese Patients with Chronic Hepatitis B.

Background: This study aimed to provide a detailed and comprehensive analysis of serum hepatitis B surface antigen (HBsAg), HBeAg, and serum hepatitis B virus (HBV) DNA in Chinese patients with chronic hepatitis B (CHB), predominantly genotypes B and C.

Methods: HBV serological markers, HBsAg titer, HBeAg titer, and HBV DNA were detected and genotyped in 129 Chinese patients with CHB.

Results: HBeAg-positive CHB patients were younger, had higher serum alanine aminotransferase, aspartate transaminase, and HBV DNA levels and were more likely to be infected with HBV genotype C.
