Objective To investigate the clinical efficacy of dl-3n-butylphthalide and its effect on NT-proBNP levels and inflammatory cytokines of patients with acute cerebral infarction.Methods Total 118 patients with acute cerebral infarction in Hengshui Fifth People's Hospital were randomly divided into control group and observation group.Sixty patients in control group were treated with conventional medication,and 58 patients in observation group were treated with dl-3n-butylphthalide injection based on conventional medication.The NT-proBNP levels,score of neurological deficits (NIHSS),inflammatory cytokines including hypersensitive C-reactive protein (hs-CRP),interleukin-6 (IL-6),and tumor necrosis factor-cα (TNF-α) before and after 7 and 14 d of treatment,and adverse reaction were observed and analyzed.Results Before treatment,differences in the NT-proBNP levels,NIHSS score,hs-CRP,IL-6,and TNF-α between two groups were not obvious.After 7 and 14 d of treatment,NT-proBNP levels in observation group were significantly lower than those in control group (P ＜ 0.05).And after treatment for 14 d,NIHSS score in observation group were conspicuously lower than those in control group (P ＜ 0.05).Additionally,the levels of hs-CRP,IL-6,and TNF-α in observation group were markedly lower than those in control group (P ＜ 0.05).Conclusion D1-3n-butylphthalide injection has a good ability in inhibiting NT-proBNP levels and inflammatory cytokines,and improves the neurological function of patients with acute cerebral infarction.

OBJECTIVE: To compare the ELISA and Pharmica unicap reagents of Dermatophagoides pteronyssinus specific IgG4 in clinic. METHOD: The stability of ELISA reagent was studied first with parameters of intra and inter assay variations (%CV). Calibration curve of the two reagents was compared. Sixty-five serum samples before or after standardized specific immunotherapy were examined with the two methods, correlation coefficient was calculated. RESULT: The stability of ELISA reagent was good with low intra and inter assay variations (3.48% and 5.78%). Calibration curve of the two reagents was similar. The correlation coefficient was 0.93 between the two test methods. CONCLUSION The results of ELISA and Pharmica unicap reagents of Dermatophagoides pteronyssinus specific IgG4 were highly consistent. The ELISA reagents could be applied in clinic.
