OBJECTIVE：To investigate the effects and mechanism of puerarin （Pue） on hypoxia-induced pyroptosis of pulmonary artery smooth muscle cells （PASMCs）. METHODS ：PASMCs of rats as research objects were randomly divided into normoxia group ，hypoxia group and hypoxia+Pue group （0.2 mmol/L）. Except for normoxia group ，other groups were cultured with 5％ CO2 and 3％ O2 at 37 ℃ for 24 hours to establish hypoxia model. Western blot assay was used to detect the expression of pyroptosis related proteins [NOD-like receptor protein- 3 （NLPR3），caspase-1，interleukin-1 β （IL-1 β），apoptosis-associated speck-like protein （ASC）]. Lactate dehydrogenase （LDH）release assay was used to detect the release of LDH in cells ；Hoechst 33342/PI double staining test was adopted to detect the proportion of pyroptosis positive cells. PASMCs was randomly divided into normoxia group+control plasmid group ，hypoxia+control plasmid group ，hypoxia+over-expression plasmid group and hypoxia+ over-expression plasmid+Pue group. Except for the normoxia+control plasmid group ，the other groups were established hypoxia model by the same method. After transfection of control plasmid or NLRP 3 over-expression plasmid ，Western blot ，LDH release test and Hoechst 33342/PI double staining test were used to investigate whether Pue could inhibit hypoxia-induced PASMCs pyroptosis by interfering with the activity of NLRP 3 inflammasomes. RESULTS ：Compared with normoxia group ，the expression of pyroptosis related proteins ，the release of LDH and the proportion of pyroptosis positive cells were increased significantly in hypoxia group （P＜0.05 or P＜0.01）. Pue had the effect of reversing the above indexes （P＜0.05 or P＜0.01）. When the NLRP 3 inflammasome was over-expressed ，the expression of pyroptosis related proteins ，the release of LDH and the proportion of Δ 基金项目：黑龙江省自然科学基金资助项目（No.ZD201416） pyroptosis positive cells were increased significantly （P＜0.05 ＊教授，博士生导师 ，博士。研究方向 ：心血管药理学 。电话： or P＜0.01）.

p38 mitogen-activated protein kinase (p38) is a member of MAP kinase family. Its widespectrum roles in the control of energy metabolism have been indicated in numerous studies. P3 8 participates in the energy metabolism in all major tissues/organs involved in the control of energy metabolism, including adipose tissue, skeletal muscles, islet cells, and liver. In white adipose tissue, p38 plays an important role in adipose differentiation and glucose uptake although it is still inconclusive whether this role of p38 is stimulatory or inhibitory. The stimulatory role of p38 in transcription of the uncoupling protein 1 ( UCP1 ) gene in brown adipose tissue is relatively clear. A fundamental role for p38 in the differentiation of skeletal muscles and mitochondrial biogenesis in skeletal muscles is rather definitive although the role of p3 8 in glucose uptake of skeletal muscles remains controversial. In islet cells, p38 appears to be involved in β-cell apoptosis. P38 has been indicated in the control of preproinsulin gene transcription, but remains controversial. However, it seems clear that p38 does not play a significant role in insulin secretion. In the liver, p38 plays a central role in hepatic glucose and lipid metabolism. Activation of p38 participates in the processes to increase blood glucose levels through reducing glycogen synthesis and increasing hepatic gluconeogenesis. P38 appears to prevent fat storage by inhibiting hepatic lipogenesis and promoting fatty acid oxidation in the liver. Additionally, p38 may play a critical role in cholesterol metabolism by regulating expression of the LDLR gene and bile metabolism. P38 does not only participate in various physiological and pathophysiological processes in cardiomyocytes, but also is heavily involved in the development of atherosclerotic lessions through its influences on monocytes/macrophages, vascular endothelial cells, and vascular smooth muscle cells.

We have developed an antibody-captured sandwich-type enzyme linked immunosorbant assay(ELISA) with monoclonal anti-IgA/a (human) and monoclonal anti-HBc, and determined immunogloblin A against hepatitis B core antigendgA anti-HBc) in sera of 179 cases of various types of HBV infection. IgAanti-HBc in the patients with acute hepatitis B (14 cases) and severe hepatitis (7 cases) was all positive, while in the patients with chronic active hepatitis, cirrhosis, chronic persistent hepatitis, and symptomatic carriers the positive rates were 94% (47/50 cases), 83.3% (10/12 cases), 56.5%(26/46 cases) and 4%(2/50 cases), respectively. Our observations suggested that IgA anti-HBc may reflect hepatic damage in the patients with HBV infection. Its detection may be valuable in the diagnosis and prognosis HBV infection. In addition, the activity of IgA anti-HBc in chronic hepatitis B is related to HBeAg.
