Abstract: ObjectiveTo study the relevant pathogenic factors, Thromboxane B₂ (TXB₂), oxidized low density lipoprotein (OxLDL), lipoprotein(a) (Lp(a)), and homocysteine (Hcy), in patients with cerebral infarction and the correlation among them. Methods205 patients and 40 health persons (the control) were measured with the plasma TXB₂, 6-keto-prostaglandin F_1α (PGF_1α) and TXB₂/6-keto-PGF_1α (T/6-K), OxLDL, Lp(a), Hcy within 24 h. Results and ConclusionThe levels of plasma TXB₂, T/6-K，OxLDL, Lp(a), and Hcy significantly increased compared with the controls (P<0.01). OxLDL was correlated with Lp(a); TXB₂ was correlated with T/6-K and Hcy; T/6-K was correlated with OxLDL, Lp（a）.

Key words: cerebral infarction, Thromboxane B₂ (TXB₂), oxidized low density lipoprotein (OxLDL), lipoprotein(a) (Lp(a)), homocysteine (Hcy), correlation
