In this study,two SNPs of chicken FASN gene were chosen to analyze genetic diversity and their associations with chicken growth and carcass traits by using a F_2 designed resource population.Results showed that:(1) In the PCR-RFLP site of HaeⅢ,allelic frequencies differed much among different chicken breeds,as B frequencies are the highest in Red Jungle Fowl(0.85),and the lowest in Taihe and Yugan Black(both 0.21).In the PCR-RFLP site of PstⅠ,A frequencies are the highest in Chongren Partridge(0.5),and the lowest in Naked Neck chicken(0.19),and the difference of gene frequencies was small among chicken breeds.

The lack of liver and kidney type PBMC in patients with alopecia areata Thl/Th2 type cytokine gene expression imbalance, presented to Th1-type cytokines and transcription factor T-bet gene over-expression of Th1-type response characteristics, may be involved in the pathogenesis of alopecia areata, alopecia areata may be insufficient evidence of liver and kidney-shaped one of the micro-nature.

肝肾不足型斑秃患者PBMC中Thl/Th2型细胞因子基因表达失衡，呈现以Th1型细胞因子和转录因子T-bet基因过度表达为特征的Th1型反应，可能参与了斑秃的发病机制，也可能是斑秃肝肾不足证型的微观本质之一。

Abstract〗 Objective To investigate the effect of gene gun transduction of Kras antisense gene on cell growth in human pancreatic carcinoma.

摘要〗 目的探讨基因枪转导Kras突变反义基因对胰腺癌细胞生长的影响。

Objective To discuss the relationship between Kras gene activation and MTS1/p16 gene mutation/deletion and the progression of endometrial carcinoma.

目的 探讨Kras激活与MTS1/p16基因突变/缺失在子宫内膜癌中的发生发展关系。

Gene gun transduction of Kras antisense gene into carcinoma cell can significantly inhibit cell growth of Kras mutant pancreatic carcinoma cell lines.

It means that decreased expression of Adipo R2, Krs, TNF-αmight be relateted to the action of lipid metabolism by EA treatment, and the down-regulation of Utr gene expression was might be involved in cell damage after simvastatin treatment. To confirm the effect of simvastatin on the changes of gene expression and the state of cell growth, C2C12 was treated in 0, 1, 3, 10, 30 and 100μmol/L of simvastatin.

在正常组、高脂组、辛伐他汀组、针治组、针预组、针非组6个组中，AdipoR2和Krs在针治组表达量最低，TNF-α在针非组中最低，Utr在他汀组中最低，与差异基因的筛选结果一致；同时也说明AdipoR2、Krs、TNF-α在针刺组中下调表达可能与其降脂作用有关；而Utr基因在他汀组中表达减少，可能与该药对肝细胞的损伤作用有关。
