非小细胞肺癌的EGFR表达与EGFR基因突变的比较

open access: yesZhongguo shiyan zhenduanxue, 2009
目的探讨非小细胞肺癌(NSCLC)表皮生长因子受体(EGFR)免疫组化表达与EGFR基因突变的关系及其临床意义。方法对130例手术切除的非小细胞肺癌组织应用免疫组化方法检测EGFR表达,同时应用基因测序方法检测EGFR基因突变,研究EGFR表达与EGFR基因突变的关系。结果130例NSCLC中有38例EGFR基因突变,突变率为29.2%。EGFR阳性率为67.7%。EGFR表达与基因突变无关(P>0.05),结论EGFR免疫组化表达与EGFR基因突变无关,不能作为筛选EGFR酪氨酸激酶抑制剂(TKI ...

The research of the detection of thalassaemia multiple mutations by next-generation sequencing technology [PDF]

open access: yes, 2015
地中海贫血又称珠蛋白生成障碍性贫血,早期的病例来自地中海地区,故称为地中海贫血,是世界范围内影响最大的单基因病之一,遵循孟德尔遗传定律。该病是由珠蛋白基因的缺失或点突变所致,根据其变异的肽链可分为α地贫和β地贫。由于其基因缺陷的复杂、多样,使缺乏的珠蛋白链类型、数量、临床症状变异较大。临床上对中、重度地中海贫血无行之有效的治疗方法,给社会、家庭、个人带来了沉重的经济及精神负担。故有效检出地中海贫血患者、进行婚前孕前指导、产前诊断、避免地中海贫血患儿的出生,有着极其重要的社会意义 ...

Promoting Conservation and Coexistence: The Case of Blackbucks (Antilope cervicapra L.) and the Bishnoi Community in Abohar, Punjab, India 促进保育与共存:以印度旁遮普邦阿博哈尔的黑羚 (Antilope cervicapra L.) 和比什诺伊社区为例

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 393-404, September 2025.
We studied the challenges in human‐wildlife coexistence in Abohar wildlife sanctuary and the surrounding landscape in Punjab, India. We found that the local people's unique intrinsic motivation for conservation and the traditional approaches to conservation are no longer sufficient.

Constructhion and Eukaryotic Expression of FBXW7α and Effects On Migrationof Cholangiocarcinoma Cell [PDF]

open access: yes, 2015
胆管癌是起源于胆管上皮的一种恶性肿瘤,近年来在全球的发病率逐年升 高,目前占据消化道肿瘤的3%,胆管癌患者5年生存率不足5%;并且这一状况 30年未曾改变。由于起病隐匿,发现比较困难,手术效果并不理想;为此我们 寄希望于采取新一代的基因诊断提高发现率;有人对人类多种肿瘤做了基因突变 测定,发现FBXW7在胆管癌中突变率较高。FBXW7有三种亚型,分别为FBXW7 α、FBXW7β和FBXW7γ;FBXW7α含有一个F-box基序,该基序直接与Skp 蛋白结合构成完整的SCF(Skp-cullin-F ...

Transformation of social‐ecological systems in the Songhua River Basin, Northeast China: Lessons for a more sustainable development

open access: yesPeople and Nature, Volume 7, Issue 7, Page 1749-1768, July 2025.
Abstract Social‐ecological systems (SES) are coupled systems formed by the intricate interactions between humans and nature. Our movement towards sustainable lifestyles requires a robust understanding of these interactions. Achieving a sustainable win‐win situation for both social and ecological systems, therefore, necessitates a sound scientific ...

The role of LRP1 in microglia and neuroinflammation [PDF]

open access: yes, 2016
神经炎症以中枢神经系统中小胶质细胞的激活、炎症因子以及趋化因子的大量表达为特征。小胶质细胞作为脑内最主要的免疫和吞噬细胞,在神经损伤以及包括阿尔兹海默症(Alzheimer’sdisease,AD)在内的神经退行性疾病中过度激活,同时起到神经保护或者毒性损伤功能。作为载脂蛋白E(apolipoproteinE,apoE)和β淀粉样蛋白(amyloid-β,Aβ)最主要的受体,低密度脂蛋白受体相关蛋白1(low-densitylipoproteinreceptor-relatedprotein1,LRP1)
