Abstract:
Objective To investigate the relationship of hypoxia inducible factor-1 α(HIF-1α),tumor necrosis factor-α (TNF-α),hepatocyte growth factor (HGF) and cerebral infarction.Method Two hundred and twelve cases with acute cerebral infarction in the Fourth People's Hospital of Langfang from Jun.to Dec.2013 were divided into progressive cerebral infarction(PCI) group(n =105) and the stability of cerebral infarction (SCI) group (n =107).Meanwhile 100 healthy people were served as control group.Enzyme-linked immunosorbent assay(ELISA) was applied to detect the levels of HIF-1 α,TNF-α and HGF.The PCI group were divided into small groups according to nerve function or infarction lesion size,and the levels of HIF-1 α,TNF-α and HGF of each group.Result The levels of HIF-1 α,TNF-α,HGF in PCI group were (2.3 ± 1.3) ng/L,(4.0 ± 0.5) mg/L and (1.4 ± 0.3) μg/L,significantly higher than those in SCI group ((1.1 ± 0.5) ng/L,(3.1 ±1.3) mg/L and (0.7 ±0.4) μg/L;F=5.42) and control group((0.5 ±0.1) ng/L,(1.8 ±0.4) mg/L and (0.4 ±0.1) μg/L;F =3.14).Meanwhile,the levels of HIF-1 α,TNF-α,HGF in SCI group was significantly higher than that of the control group (F =1.32,P ＜ 0.05).The levels of HIF-1α,TNF-α,HGF in mild PCI group were significantly lower than those in moderate group and severe group,and those in moderate group was lower than those in severe group (F =0.93,4.32,2.31 ; P ＜ 0.01).The levels of HIF-1 α,TNF-α,HGF in small infarction group were (0.6 ± 0.4) ng/L,(2.7 ± 0.4) mg/L,(0.7 ± 0.4) μg/L,significantly lower than those in infarction group ((1.1 ± 0.5) ng/L,(4.4 ± 0.5) mg/L,(1.1 ± 0.2) μg/L; F =4.71,P＜0.05) and large infarction group((1.4 ± 0.6) ng/L,(4.8 ± 0.6) mg/L,(1.9 ± 0.5) μg/L; F =2.09,P＜0.05).The levels of HIF-1α,TNF-α,HGF in focal infarction group was significantly lower than that in large infarction group and the difference is statistically significant(F =2.45,P ＜0.05).Conclusion HIF-1 α,TNF-α and HGF serum levels in progressive cerebral infarction are significantly increased,which is related to the function defect and size of infarction.
