Objective To explore the mechanism of the protection of acidic fibroblast growth factor (aFGF) for hippocampal astrocytes from injury induced by gentamicin. Methods Hippocampal astrocytes were isolated from newborn (24 hours) Sprague-Dawley rats, puri-fied, and identified with glial fibrillary acidic protein (GFAP) immunofluorescence. The third generations were cultured for 3 days and divid-ed into 3 groups:control group was cultured routinely, injury group was cultured with 2.0 g/L gentamicin for 24 hours, and protection group was cultured with 4.25μg/L aFGF for 24 hours and then cultured with 2.0 g/L gentamicin for 24 hours. Western blotting was adopted to de-tect the expressions of P38, extracellular signal-regulated kinase (ERK)1/2 and c-Jun N-terminal kinase (JNK)1/2. Results Hippocampal as-trocytes were culturated successfully with the purity above 95%. The ERK1 increased in the injury group compared with the control group (P<0.05). Compared with the injury group, the p38 increased (P<0.05) and the ERK1 decreased (P<0.05) in the protection group. There was no significant difference among others (P>0.05). Conclusion The mitogen-activated protein kinase signal pathway, especially P38 and ERK1, may associate with the protection of aFGF for hippocampal astrocytes from injury induced by gentamicin.

Objective To explore the correlation between left ventricular hypertrophy (LVH) and dynamic parameters of blood pressure as well as blood pressure variation in patients with essential hypertension (EH). Methods From January to September, 2013, 581 patients with EH were divided into hypertrophy group (n=161) and non-hypertrophy group (n=420) according to the left ventricular mass index (LV-MI). The clinical data, biochemical indexes and dynamic parameters of blood pressure were compared, and the multiple factors regression was used to analyze the risk factors of LVH. Results The incidence of LVH was higher in women than in men (χ2=4.836, P=0.03), the level of blood uric acid was higher in the hypertrophy group than in the non-hypertrophy group (t=-11.540, P<0.001). The clinic systolic blood pressure was higher in the non-hypertrophy group (t=-3.805, P<0.001). There was significantly difference in 24-hour systolic blood pres-sure load, systolic blood pressure drops at night and average systolic blood pressure between two groups (t>2.770, P<0.05). Multi-factor Lo-gistic regression analysis showed that gender (OR=1.674, P=0.044) and 24-hour systolic blood pressure load (OR=1.021, P=0.003) associat-ed with LVH. Conclusion The occurrence of LVH in patients with EH was closely related to the 24-hour systolic blood pressure load, and was higher in women than in men.
