果蝇的enterocyte differentiation (polyploidization) depends on Notch

际科学界的难题,而这一基础科学问题也与人类、特别是中国人民的健康相关。
过去,世界和中国忽略了1980年代我国科学家在条件艰苦时代做出重要贡献,我们现在
应该赞广西肿瘤防治研究所的严瑞琪和苏建家等、北京第二传染病院的余昌晏等和中国
医学科学院的庞其方等建立乙肝动物模型;
现在,我国已经有条件和能力改革科学管理体制机制、提供适当环境,让一些科研机构
年富力强的科学家心无旁骛,如北京生命科学研究所的李文辉带领学生和同事发现乙肝
病毒受体;
将来,希望全国科研机构能推广适合各个学科和机构自身规律的体制机制改革,使大批
年轻人集中精力在专业上充分发挥作用,他们大有作为才能使中国的科学大有希望。
肝炎和肝炎病毒
肝炎在全世界有广泛的危害,中国人群肝炎患病率尤其高。多种病毒导致病毒性肝炎:
甲、乙、丙、丁、戊(A、B、C、D、E)等。
全球二十亿人曾感染乙型肝炎病毒(HBV),慢性乙肝感染超过3.5亿人。即使在乙肝疫

据大家的经验,这个效率大概是多少呢?(如果能讨论下特异性就更好了)
另外,liver大概有70%的细胞是hepatocytes,剩下的就是其他细胞了,transfection
是针对所有的细胞吗?有没有特异性的针对hepatocytes的。

患者44岁,男,6年前因为肝癌做了肝移植 (符合米兰标准),之后无灾无病好几年。

内发现一个肿瘤,内镜医生直觉是GIST。随后CT,但CT却没有异常。4月初第二次胃镜
,GIST依然还在,取样活检表明可能肝癌转移或者是非常罕见的HAC。第二次CT 报告大
小46x35mm,说比较第一次32mm变大了。可能第一次看片医生那天喝多了?肿瘤位置在

AFP好久没有查了,因为肝上的情况一直很好,肝移植前AFP 100多,移植后AFP一直小
于2。上一次至少是2,3年前。也是疏忽了。现在AFP 254. 显然胃上这个要么是转移,

容易。其他几种常温下是液体,但是大体上他们的密度和水的密度很相近,1ml近似1g
。这些脂肪酸都极易溶于乙醇。溶解Palmitic Acid需要略微加热(50C)。
The free fatty acids are toxic unless they are presented bound to purified,
fatty acid free, endotoxin-free serum albumin, which is used at a typical
concentration of 0.1–0.2%.
Take 31ul 1M palmitic acid, 2.8ul 1M Palmitoleic acid etc and bring the
final volume to 1000ul with 100% EtOH, you will get 0.1M FFA. Add 76ul of
the mixture to 1L culture medium and you w... 阅读全帖 |

入bias,而所谓的statistical significance有时候也不能说明问题。究竟有没有关联
HBV在其中又实际起了什么作用,很难说。
目前HBV在HCC中的作用都还停留在“假说”阶段,更别提什么pancreatic cancer了。
HBV的体外复制是严格肝细胞特异性的,而体外感染更是只能在primary hepatocytes上
实现(HepRG cell是一个例外),体内也未见有HBV感染pancreatic cell的报道。
假如HBV真的与pancreatic cancer相关的话,我个人倾向于认为,同样是基于某些间接
因素,编码产物直接作用于pancreatic cell,可能性很小

猜测这些不会是很好的target。PreS1 derived peptide作为entry inhibitor目前据说
效果已经非常好了,另有其他一些entry inhibitory peptide/molecule在pre-
clinical阶段的效果也不错,所以我估计眼下针对“疑似”receptor的rational
design不会有太大的吸引力。
chronic HBV治疗,要说最终解决还是得靠免疫学的方法,传统的NRTI也好,entry
inhibitor也罢,治标不治本,解决不了问题。强效Interferon以及前几天热炒的
Adoptive T cell therapy,我觉得应该是目前看来最有前景的方向吧,这玩意在国内
时市场太大了。
是了

p*****m 发帖数: 7030 | 50 我理解你的意思 不过国内靠大分子药我觉得还是不靠谱 太贵了 用起来又不方便 1亿携
带者呢。。。国内还是要靠疫苗外加小分子药物。而小分子药物最直接的就是block病毒
entry.
当然了,你可以说乙肝携带者其实大多数的肝细胞都已经被侵染了 阻止entry用处不大
。但是现在乙肝在肝细胞之间怎么transfer的似乎了解的不是很清楚,也许阻止entry会
有意想不到的效果?(比如说,virus transfer对维持病毒的存在是关键的)
