The reliability and validity of the Chinese version of the 17-item Hamilton Depression Rating Scale (CHDS) was assessed. Interrater reliability was excellent, the item total-score correlations were good, and the internal reliability was satisfactory. The concurrent validity was tested by correlating the CHDS score with the Global Assessment Scale score; the(More)
The aquaporins (AQPs) are a family of homologous water channels expressed in many tissues. In this study, the expression and immunolocalization of different AQP subtypes in rat brains were investigated by RT-PCR, immunohistochemistry and immunofluorescence. The data showed that AQP1 was expressed in the subpial processes of astrocytes, choroid plexus and(More)
The results of retrospective-cohort radioepidemiological studies on workers of mines and plants governed by China National Nuclear Corporation was reported. The total number was 40,122 persons and 575,411 person-years. The accumulated personal dose in workers of reactor, nuclear fuel reprocessing plants and research units was 57 mSv on the average. For fuel(More)
Genetic analysis was conducted on the data of 3 populations with 1,686 litters including Erhualian pig, Large White and first cross. The results indicated that the heritability estimates for the total number of piglets born, the number of piglets born alive, the number of piglets at 20 d and at 45 d were 0.081, 0.156, 0.402 and 0.419, respectively. The(More)
Genetic analysis was conducted on the data of 3 populations with 1686 litters including Erhualian pigs, Large White and first cross. The phenotypic and genetic parameters among litter weight at birth (LW), average piglet weight at birth (APW), litter weight at 20 days (LW20), average piglet weight at 20 days (APW20), litter weight at 45 days (LW45), average(More)
A novel approach was established to predict toxicity of environmental pollutants by using green fluorescent protein (GFP) as bio-marker. In the approach, recombinant Escherichia coli was constructed to express GFP. The toxicity values (-lgEC (50)) of 14 halogenated phenols to recombinant E. coli with GFP gene were measured. And optimized calculation was(More)
