Study on the mechanism of FBXW7 protects against insulin resistance via regulating FetuinA protein level [PDF]

open access: yes, 2016
目的:FBXW7属于SCF类泛素连接酶E3,可调控脂质代谢关键转录因子和胰岛功能相关蛋白的泛素化降解。FetuinA是一类参与机体糖脂代谢调控的重要肝脏因子,与胰岛素抵抗发生密切相关,但在肥胖状态下肝脏中蛋白水平异常升高机制不得而知。本研究拟探究FBXW7在肥胖状态下对FetuinA蛋白水平调节机制,有助于进一步完善肥胖致胰岛素抵抗机制。 方法:本课题结合高脂饮食诱导的HFD肥胖小鼠模型和正常饮食诱导的ob/ob小鼠肥胖模型,检测小鼠糖脂代谢相关指标,采用Real-timePCR和ELISA ...

Association of maternal body mass index with hemodynamic and vascular alterations at 35–37 weeks' gestation

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 3, Page 303-310, March 2025.
ABSTRACT Objective Globally, one in four pregnant women is classified as overweight or obese, based on their prepregnancy body mass index (BMI). Obese pregnant women are at increased risk of adverse pregnancy outcomes and long‐term cardiovascular disease that occurs earlier in life.

The AMP-mimetic AICAR prevents HFD-promoted hepatosteatosis and inhibits liver tumorigenesis [PDF]

open access: yes, 2015
肝细胞癌(Hepatocellularcarcinoma)是最常见的肝脏原位肿瘤。肝癌的 危险因素包括酒精性肝疾病、非酒精性肝炎、肝炎病毒感染等。这些因素都和肝 癌形成中炎症有重要关系。肥胖人群中,肝脏脂质积累造成的非酒精性脂肪肝炎, 肥胖已成为肝癌形成的潜在危险因素。流行病学研究表明,超重和肥胖增加了癌 症发生的风险。在升高体重指数超标的肝癌患者中,由于肝癌死亡的风险是正常 人的4.5倍。文献报道,肥胖通过增加白介素6和肿瘤坏死因子的表达促进肝脏 炎性过程 ...

Maternal prepregnancy weight as an independent risk factor for congenital heart defect: systematic review and meta‐analysis stratified by subtype and severity of defect

open access: yesUltrasound in Obstetrics &Gynecology, Volume 64, Issue 3, Page 294-307, September 2024.
ABSTRACT Objective To assess the association between increased maternal prepregnancy body mass index (BMI) and the risk of congenital heart defect (CHD) in offspring. Methods This systematic review and meta‐analysis searched PubMed/MEDLINE, Web of Science and Scopus from inception to 20 April 2023.

The relationship between the levels of white blood cell and lipopolysaccharide binding protein and intrahepatic triglyceride content , metabolic abnormalities in obese adults [PDF]

open access: yes, 2016
研究目的 非酒精性脂肪性肝病(NAFLD)常常伴随炎性因子的增多,且其发生发展与代谢综合征和胰岛素抵抗紧密相关。本研究针对中心性肥胖人群进行横断面数据分析,探讨白细胞(WBC)及脂多糖结合蛋白水平(LBP)与肝脏脂质含量(IHTC)及其相关代谢异常的关系。 研究方法 本研究纳入485名40-65岁中心性肥胖受试者,进行问卷调查包括病史、生活方式等;测定生化指标并进行胰岛功能评估;通过氢质子磁共振波谱(1H-MRS)技术定量分析肝内甘油三酯含量;进行内脏脂肪含量等测定 ...

The effect of PNPLA3 ploymorphism in the intervention of non-alcoholic fatty liver disease [PDF]

open access: yes, 2015
研究目的 运动是治疗非酒精性脂肪性肝疾病的一个重要方法,而脂肪滋养蛋白基因(PNPLA3)是非酒精性脂肪性肝疾病的一个重要的基因遗传因子。本研究的目的是为了探讨脂肪滋养蛋白基因的多态性表达是否影响到运动干预非酒精性脂肪性肝疾病的过程。 研究方法 本研究共招募40-65岁中心性肥胖受试者1059人,进行常规体检,并运用彩超检测脂肪肝。并随机抽取476名肥胖受试者进行1H-MRS对其肝内甘油三酯进行定量测定。在这476名肥胖受试者中,随机抽取220人分为三组,强化运动组(先进行6个月的强化运动期 ...

Relationship between abnormal symptoms of Prader-Willi syndrome model --Snord116 deletion mice and Ghrelin signaling pathway [PDF]

open access: yes, 2016
Prader–Willi综合症是以进食异常和血液Ghrelin异常升高为特征的遗传肥胖症。其病因是Snord116SnoRNA群的表达缺失。我们构建的Snord116del小鼠模型表现出贪食和血液Ghrelin升高等PWS症状。此次研究中,我们繁育野生型(WT)、Snord116del(SW)、Ghrl-/-(WG)、Ghsr-/-(WR)小鼠,并制备[Snord116del,Ghrl-/-](SG)和[Snord116del,Ghsr-/-](SR)双敲除小鼠,对其生长发育 ...

Effects of interword spacing on native English readers of Chinese as a second language [PDF]

open access: yes, 2016
Interword spacing facilitates English native readers but not native readers of Chinese, a writing system that does not mark word boundaries. L1-English readers of Chinese as a Second Language (CSL) could then be facilitated if spacing is added between ...

Total gastrectomy vs subtotal gastrectomy for the Control of blood pressure on spontaneously hypertensive rats and the exploration of underlying mechanism [PDF]

open access: yes, 2015
背景:我们的临床研究发现胃癌合并原发性高血压的病人,进行全胃切除术及胃大部切除术后,降压效果有显著差异。也有文章提出,胃减容手术能够有效改善肥胖患者的血压。因而我们推论,单纯胃切除术即可对血压产生影响。胃减容手术在肥胖个体上改善血压的效果被主要归因于体重的降低;而水钠代谢的紊乱被认为是原发性高血压的重要发病原因之一,胃转流手术对于水钠代谢的改善作用也已被人所验证。那么胃切除手术改善血压的原因可能也是由于这两者的作用。因此,本实验的研究目的在于对比单纯胃大部切除及单纯全胃切除术对原发性高血压大鼠体血压 ...
