MATERNAL RNAs stored in eggs play an essential role during the initial stage of embryonic de-velopment in animals and they are degraded as the development proceeds. In some animals (e.g. fish and amphibian), zygotic genes begin to transcribe new mRNA only when the embryosdevelop to about midblastula stage. This degradation of maternal RNA and synthesis of

Zebrafish has become particularly attractive for understanding the development of vertebrate sensory organs and presents many advantages for studying hair cell differentiation and regeneration.A large number of genes implicated in otic development have been identified in this model using different approaches,some of which were associated with human diseases affecting hearing function(Blanco-Sanchez et al.,2017;Nicolson,2017).

BACKGROUND: liver revascularization is frequently required during the enlarged radical operation for hilar cholangio carcinoma involving the hepatic artery. Researchers have carried out a number of experiments applying partial porta vein arterialization (PVA) in clinical practice. In this study we aimed to establish a theoretical basis for clinical application o partial PVA and to investigate the effects of partial PVA on ra hilar bile duct and hepatic functions. METHODS: Thirty rats were randomly and equally assigned into 3 groups: control (group A), hepatic artery ligation+bile duct recanalization (group B), and partial PVA+bile duc recanalization (group C). Proliferation and apoptosis o rat hilar bile duct epithelial cells, arteriolar counts of the peribiliary plexus (PBP) of the bile duct wall, changes in serum biochemistry, and pathologic changes in the bile duc were assessed 1 month after operation. RESULTS: The proliferation of hilar bile duct epithelial cells in group B was greater than in groups A and C (Plial cells were detected in any of the groups. The PBP arteriolar counts of the hilar bile duc wall were similar in groups A and C (P>0.05), but the coun was lower in group B than in group A (Pline phosphatase and albumin were found in the 3 groups. The gamma-glutamyltransferase value was higher in group B than in groups A and C (Pshowed no significan abnormality. Chronic inflammatory changes in the hilar bile duct walls were observed only in group B. CONCLUSION: Partial PVA can restore the arterial blood supply of the hilar bile duct and significantly extenuate the injury to hilar bile duct epithelial cells resulting from hepatic artery ligation.

和谐消费环境是构建社会主义和谐社会的重要组成部分。和谐消费环境的实质就是,在消费领域,人与人、人与社会、人与自然之间能互惠互利、协调发展、和谐相处。现阶段和谐消费环境的建设要转变思路,除继续发挥国家正式制度的作用外,还要充分认识到非正式制度等社会资本的作用。因为社会资本是资源配置的第三种方式,它具有节约交易成本和促进信息流动等作用,有利于和谐消费环境的建设。

目的:了解阻塞性睡眠呼吸暂停低通气综合征与胰岛素抵抗之间的关系及经鼻持续气道正压通气对胰岛素抵抗的影响。资料来源:应用计算机检索Medline 2004-01/2006-12相关文章,检索词“obstructive sleep apnea-hypopnea syndrome,insulin resistance CPAP”,并限定文章语言种类为English。同时计算机检索万方数据库2000-01/2006-12期间的相关文章,限定文章语言种类为中文,检索词“阻塞性睡眠呼吸暂停低通气综合征,胰岛素抵抗,经鼻持续气道正压通气”。资料选择:对资料进行初审,选取有关阻塞性睡眠呼吸暂停低通气综合征和胰岛素抵抗的文献,纳入标准:①文献能证明二者之间的关系。②治疗组为阻塞性睡眠呼吸暂停低通气综合征组。③对照组为正常人。④经鼻持续气道正压通气治疗前后空腹胰岛素水平和胰岛素敏感指数的变化。资料提炼:共收集到35篇有关阻塞性睡眠呼吸暂停低通气综合征和胰岛素抵抗的文章,33篇符合纳入标准。排除的2篇试验中,皆因系重复的同一研究。资料综合:对剩余的33篇文献全文中的相关信息进行分类综合研究。治疗组空腹胰岛素较对照组高,胰岛素敏感指数降低,在治疗后空腹胰岛素水平降低,而胰岛素敏感指数提高。结论:阻塞性睡眠呼吸暂停低通气综合征与胰岛素抵抗之间有着显著的相关关系,经经鼻持续气道正压通气治疗可提高患者的胰岛素敏感性,改善患者的胰岛素抵抗现象。
