Objective To investigate the effect of atorvastatin calcium on serum endothelin-1(ET-1), polyamine oxidase(PAO), heart-type fatty acid binding protein(H-FABP), vascular endothelial growth factor(VEGF), 100β, inflammatory cytokines and nerve function in patients with acute cerebral infarction.Methods According to the random number table, 113 patients were randomly divided into two groups (n=61) and control group (n=52).The control group received conventional treatment methods, and observation group received atorvastatin calcium on the basis of control group. The treatment course was two weeks.Serum ET-1, PAO, H-FABP, VEGF, S100β, inflammatory cytokines and NIHSS score were compared between two groups before treatment, 7d and 14d after treatment.Results The serum levels of ET-1, PAO, H-FABP after 7d, 14d treatment of observation group was significantly lower than that of control group, respectively (P<0.05).The VEGF level of observation group after 7 d, 14 d treatment of observation group was significantly higher than that of control group, respectively (P<0.05).The S100βlevel after 7 d, 14 d treatment of observation group was significantly lower than that of control group, respectively (P<0.05).The hs-CRP, IL-8, TNF-αlevels after 7 d, 14 d treatment of observation group was significantly lower than that of control group, respectively (P<0.05).NIHSS score after treatment of observation group was significantly lower than that of control group (P<0.05).Conclusion The atorvastatin calcium can improve neurological function in patients with brain injury through reducing serum ET-1, PAO, H-FABP and S100βlevels, promote angiogenesis through increasing VEGF expression, and alleviate inflammation and ischemia-reperfusion injury through reducing inflammatory cytokines, thereby promote neurological functional recovery.

Objective To observe changes of spatial learning-memory in rats with chronic hypoxic hypercapnia and the effect of gingkgo biloba extra. Methods After established the rat model of chronic hypoxic hypercapnia,seventy-two rats were randomly divided into four groups normal control (NC),hypoxic-hypercapnia 4-week (4HH),hypoxic-hy-percapnia 4-week+gingkgo biloba extra (EGb)high dose(100 mg/kg)group[4HH+EGb(H)] and hypoxic-hypercapnia 4-week+EGb low dose (50 mg/kg) group[4HH+EGb(L)]. Praxiology in rats was asessed by the Morris water maze and step down test. Results The spatial learning-memory in rats exposed to chronic hypoxic-hypercapnia 4-week(4HH group)were displayed significant impairment in their performance,the longer mean escape latencies and swim path dis tances,the more error times. 4HH+EGb(H) and 4HH+EGb(L)groups shortened the reaction time of leaning, pro longed the latent time of memory, reduced times of mistakes. Conclusions EGb can enhance the capacity of learning-memory in the rats exposed chronic hypoxic hypercapnia.
