美国开放式保护主义及我国银行业安全的法律规制

美国银行业安全的法律规制经历了近百年的演进,形成了以紧跟金融创新发展步伐的渐进性,维护国家金融主权的保护性,寻求体制内各种法律制度互补的平衡性为特征的开放式保护主义法律规制体系.借鉴美国经验,我国在金融开放,实现金融现代化的进程中,也应以公益性、安全性、程序性等诉求为依据,以法律法规的定向约束为手段,以国家利益至上为宗旨,以对国外竞争者设置制度化的市场障碍和金融市场参与者稳健经营为目的,对我国银行业安全法律规制进行完善,以维护国家金融安全.

Role of 17-AAG in inducing apoptosis and cell cycle arrest of HCT-15 cells

AIM: To investigate the effects of 17-AAG on apoptosis and cell cycle of HCT-15 cells and to clarify the related mechanisms. METHODS: MTT method was employed to evaluate the inhibitory effects of 17-AAG with Aifferent time and different doses on the proliferation of HCT-15 cells. The cells were stained with Annexin V-FITC/propidiumiodide and measured by flow cytometry. The expression of STAT3, cyclin D1, Cyt C, caspase 9 and caspase 3 at mRNA and protein levels was determined by RT-PCR and Western blotting. RESULTS: Treatment with 17-AAG at concentration of 1.25~20 mg/L for 24 h and 48 h significantly inhibited the activity of HCT-15 cells at both time-and concentration-dependent manners. Treatment with 17-AAG at concentrations of 0.425, 0.85 and 1.7 mg/L for 48 h significantly induced apoptosis and cell cycle arrest of HCT-15 cells. The exposure of 17-AAG at concentrations of 0.425, 0.85 and 1.7 mg/L for 48 h to the HCT-15 cells significantly down-regulated the expression of STAT3 and cyclin D1 at mRNA and protein levels, but up-regulated Cyt C, caspase 9 and caspase 3 mRNA and protein in a concentration-dependent manner. CONCLUSION: 17-AAG inhibits the cell activity, induces apoptosis and G₁ arrest by down-regulating the expression of cyclin D1, and promoting the mitochondria apoptosis through STAT3 pathway.     

香石竹DcMAPK1和DcMAPK2的克隆及功能初#br# 步分析

 分离了香石竹（Dianthus caryophyllus）两个促分裂原活化蛋白质激酶（mitogen-ac-tivated protein kinase,MAPK）基因cDNA 全长,分别命名为DcMAPK1 和DcMAPK2,其中DcMAPK1 与拟南 芥AtMAPK6 高度同源。DcMAPK1 在香石竹花瓣衰老过程表达增加,乙烯处理显著促进其表达,瞬时抑 制DcMAPK1 后切花瓶插寿命显著延长。而DcMAPK2 在花瓣衰老过程中组成型表达,乙烯处理对其表达 无显著影响,瞬时抑制DcMAPK2 对切花瓶插寿命无显著影响。     

海南省西甜瓜细菌性果斑病的发生与防治

<正>近年来细菌性果斑病在海南西瓜、甜瓜生产上发生严重,其原因不仅与当地气候条件、栽培管理不当等有关,也与各地进行南繁的瓜类品种繁杂、种子消毒不彻底、病原远距离传播扩散有关。西瓜、甜瓜是海南省种植面积较为广泛、经济效益较高的农产品,2013年种植面积达1.97万hm2(29.55万亩)(农业部,2015)。细菌性果斑病是西瓜、甜瓜生产上的一种毁灭性病害,引起该病的病原菌为西瓜嗜酸菌(Acidovorax citrulli)(Schaad

Cx43 is involved in electrical remodeling of atrial myocytes through regulating L-type calcium current

AIM: To investigate whether the association of connexin 43(Cx43) and L-type calcium channel involved in the pathogenesis of atrial fibrillation (AF). METHODS: The biochemical assays and whole-cell patch-clamp technique were used to study the expression of Cx43 in human atrial tissue. The co-localization of Cx43 and L -type calcium channel, and the regulation of L-type calcium current in atrial myocytes were investigated. RESULTS: The expression of Cx43 at mRNA and protein levels was decreased in human atrial tissues of AF patients. In cultured atrium-derived myocytes (HL-1 cells), knockdown of Cx43 significantly inhibited the mRNA expression of L-type calcium channel α1c subunit, as well as L-type calcium current. Co-localization of Cx43 with L-type calcium channel α1c subunit in mouse atrial myocytes was observed. CONCLUSION: The decrease in Cx43 is involved in the pathogenesis of AF, probably through reducing the L-type calcium current in atrial myoctyes by co-localization with L-type calcium channel, thus representing the potential pathogenesis in atrial fibrillation.
