Geographical distribution rule of normal reference value of old female’s hemoglobin based on factor analysis / 吉林大学学报(医学版)

Objective To reveal the geographical distribution regularity of the normal reference value of old female’s hemoglobin in China,and provide scientific basis for making its unified standards.Methods The normal reference values of 15 690 examples of old female’s hematocrit by the method of hemoglobin cyanide(HiCN)and five geographical factors in 157 areas in China,its distribution regularity and the complex relationship characteristic between geography environment elements were analyzed with the methods of factor analysis,spatial analysis of GIS and correlation analysis.Results By the method of factor analysis,the five factors of geography environment were combined into two common factors F1and F2;the original data was replaced with its scores to infer the regression equation :y

Effects of Buguozhi Decoction on gene expression of ER-?,NR2B in hippocampus of vascular dementia model rats / 中华中医药杂志

Objective:To investigate the mechanism of Buguozhi Decoction in improving learning-memory of vascular dementia model rats.Methods:The rat models with VaD were established by bilateral occlusion of both common carotid arteries(2 一V0).The gene expressions of ER-?,NR2B were evaluated by RT-PCR and immunohistochemistry.Results:Buguozhi Decoction can significantly improve mRNA and protien pruducts of ER-?,NR2B gene in hippocampus of the vascular dementia model rats,compared with the model group(P
