Relationship between Vitamin and Fetal Development [PDF]

open access: yes, 2017
胎儿在母体宫内发育经过受精卵、胚胎、胎儿三个阶段,任何影响母胎健康的病因都影响宫内受精卵、胚胎和胎儿的发育,严重者甚至导致胚胎停育、胎死宫内。缺乏维生素容易诱发人体各种疾病,孕期母体维生素的需要量增加,如果孕期母体维生素摄入不足、补充不够、未得到及时增加或增加过量,都会影响胎儿器官的正常发育,导致胎儿发育不良。有些严重的胎儿畸形是致死性的,因此孕期要注意筛查及时处理。孕期加强母胎保健,重视优生优育,改善孕妇和儿童营养状况,合理调配膳食,适当补充维生素,了解各种维生素的功效和胎儿发育的相关性 ...

High effective detection and discoveries of novel truncations of midkine in tumors [PDF]

open access: yes, 2006
Midkine是一种肝素结合性生长因子,属于Midkine家族。Midkine家族由2个因子组成,即中肾因子(midkine,MK)和多效营养因子(pleiotrophin,PTN)。MK在胚胎期广泛表达,在成年组织中的表达则仅限于肾脏和小肠上皮。近年的研究发现MK在恶性肿瘤组织中有异常的高表达,这种现象没有组织特异性,这与P53突变体非常相似。MK有多种生物学功能,在胚胎期它能促进正常细胞的生长和分化,尤其可促进神经细胞的发育,在成年期有激发某些细胞分化的激素样作用,维持肾脏的正常功能 ...

糖尿病与胰腺癌关系的研究进展

open access: yesZhongguo shiyan zhenduanxue, 2016
胰腺癌(cancer of the pancreas)是一种常见的诊断与治疗都很困难的消化道恶性肿瘤,近年来发病率呈明显上升的趋势。因其发展较快、恶性程度高,所以发现时多为晚期,同时也是预后最差的恶性肿瘤之一。临床资料分析表明,胰腺癌的发生与多种因素相关,如长期的吸烟、饮用咖啡及肥胖等。近年来,随着对胰腺癌病因和发病机制研究的不断深入,胰腺癌与糖尿病的关系越来越受到关注,但关于两者相关性尚无明确结论[1 ...

Macrophage Proliferation Machinery Drives Immunosuppression and PDAC Progression (巨噬细胞增值机制抑制肿瘤免疫促进胰腺癌发展) [PDF]

open access: yes, 2022
Tumor-associated macrophages (TAMs) are abundant in near all solid tumors and are involved in many aspects of cancer progression. The presence of TAMs is negative prognostic indicator in several cancer types including pancreatic cancer.
