别让烦躁和焦虑坏了你的"胆"

胆囊炎与胆石症属于中医的"胆胀"范畴.病因分为内因(正气虚)外因(邪气实)两个方面,内因方面一是性格过度压抑或过度暴躁,再加上饮食偏嗜、多食油腻厚味及社会压力等外因的作用,就容易导致肝疏泄失常累及胆腑,外郁蕴热而成"胆胀".     

肝孤儿受体在糖、脂质代谢中的作用

肝孤儿受体(LXRs)是近年来发现的与糖、脂质代谢密切相关的靶基因。本文深入论述了LXRs在糖、脂质等能量代谢及炎症反应过程中所发挥的重要作用,为研制、开发治疗脂代谢异常、动脉粥样硬化症、心脑血管病、糖尿病等疾病提供了新的思路。     

补糖与运动能力

运动员体内肌糖原含量低于临界值（50mM/kg湿肌）或血糖浓度低于临界值3．3mM/L)易诱发过早疲劳，在进行长时间运动时常因糖原排空而引发运动强度显著降低或中止。因此，合理地摄食高糖饮食可增加肌糖原和肝糖原贮备量，可改善耐力，维持高水平的训练质量。摄食糖的数量、类型和摄取时间三者都是改善运动后恢复速率的营养策略的组成部分。     

肝癌微环境中肝星状细胞活化及Stefin B的表达

探讨肝癌微环境中肝星状细胞(hepatic stellate cell,HSC)的活化与Stefin B表达情况。采用不同浓度TGF-β_1(5、10和20 ng/m L)、不同浓度肝癌细胞条件培养液(25%、50%和75%)以及TGF-β_1与肝癌细胞条件培养液混合的方法分别处理HSC,免疫细胞化学染色法和Western blotting法检测α-SMA和Stefin B蛋白表达,CCK-8法检测细胞增殖。结果:TGF-β_1与肝癌细胞条件培养液分别单独作用或共同作用时,HSC的α-SMA表达均升高且细胞出现活化,细胞增殖能力均增强;Stefin B在TGF-β_1单独作用时表达下调,而在肝癌细胞条件培养液单独作用及TGF-β_1与肝癌细胞条件培养液共同作用时显著升高。结果表明:肝癌微环境能够促进HSC活化及Stefin B表达。     

谈田径运动员的赛前饮食

合理的赛前饮食应该：是1.赛前几天应以复杂糖类及蛋白质为主;2.赛前2.5～3小时吃中等数量的食物；3.比赛即将开始时不宜食用大量的简单淀粉、食糖及葡萄糖;4.在比赛中（较长时间的耐力项目）饮用稀释的葡萄糖溶液.     

Acute phase reaction and acute phase proteins

INTRODUCTION The first reaction of the body to immunological stress is the innate, non-specific response preceding specific immune reactions. The acute phase response (APR) is a prominent systemic reaction of the or- ganism to local or systemic disturbances in its ho- meostasis caused by infection, tissue injury, trauma or surgery, neoplastic growth or immunological disor- ders (Gordon and Koy, 1985; Gruys et al., 1999). At the site of invasion by a micro-organism and the place of tissu…     

肝豆状核变性中的神经系统变性与铜毒性的综述

Wilson病(Wilson's disease,WD)是广泛分布于人类各种族人群中以铜代谢障碍为特征的常染色体隐性遗传病且好发于青少年。WD是一种累及多系统、多器官的全身代谢性疾病,临床上引起神经系统变性可使整个神经系统受累,而以豆状核、视丘、尾核、脑岛和带状核受累较重,以豆状核内的壳核最为显著。本文就WD中神经系统变性的临床表现、WD与铜毒性关系、以及铜毒性与神经元凋亡实验研究的新进展作一综述。     

Investigation of a spherical-section ultrasound phased array for hepatic ablation

A 3D ultrasound thermal model with a 3D finite element representation for modeling the thermal diffusion effects for hepatic ablation induced by spherical-section ultrasound phased array was developed. The model was first validated against available published measured data in rat liver. Using the validated model,effects of blood perfusion and heating schemes on lesion formation were studied for both single focus and split-focus intensity patterns. It was shown that for single focus sonication pattern the short-duration(～2 s) and high-intensity(～1250 W/cm2) heating scheme can completely reduce the cooling effect of the blood perfusion. The lesion shape and size were significantly altered by perfusion for split-focus pattern even with a rapid heating scheme when the focus spacing was larger than 2.4 mm. Underdosed areas might be present between two foci. Prolonging ex-posure time or shortening focus spacing can reduce the cool region between two foci. In addition,the influences of thermal and acoustic parameters were also studied. When the therapy depth is short(<5 cm) ,the lesion size monotonically increases with increasing attenuation coefficient that ranges from 5.4 to 11 Np/(m?MHz) .
