1. LDL功能分析:LDL负责将胆固醇从肝脏运输到外周组织。当血液中LDL浓度过高时,多余的胆固醇会被氧化并渗入血管内皮,引发泡沫细胞形成和动脉粥样硬化斑块。2. HDL的逆向运输机制:HDL可将外周组织(包括血管壁)的多余胆固醇逆向转运回肝脏进行胆汁酸转化或直接排出,这种胆固醇清除功能具备心血管保护作用。3. 临床数据支持...
HDL 携带的胆固醇主要是使之回到肝脏中去,从而得以得到代谢并排除,最后可以达到一个减少胆固醇沉积的作用,提供动脉血管的HDL,血浆胆固醇量其实是减少的。 所以说低密度脂蛋白(LDL)中的胆固醇是“bad cholesterol” ,而高密度脂蛋白(HDL)中的胆固醇是“good cholesterol”。反馈...
LDL stands for low-density lipoprotein. This is the “bad” cholesterol protein that carries cholesterol to your artery walls. You want your LDL levels to be low. Just remember that the “L” stands for low. Generally speaking, the lower the better. You need some LDL cholesterol protein to...
The chart here displays 5 cholesterol readings: total cholesterol, LDL, HDL, triglycerides and also VLDL cholesterol. It also displays the healthy range, along with risk zones pertaining to each one. To sum up, the recommended measurements for the total cholesterol are below 200. As for triglyce...
Change in LDL cholesterol with dietary fat and cholesterol was unrelated to LDL particle size in either men or women. However, change in HDL cholesterol in men was strongly related to LDL particle type (r = -0.52, P = 0.001) and change in HDL2 cholesterol in women was related to LDL ...
2009年6大国际医学机构,包括国际糖尿病联合会和美国心脏协会等6个国际医疗机构在2009年联合发表了一份共识,[1] 把代谢症候群锁定在5项身体指标上:高血糖、高血压、高甘油三酯、低HDL和腹部肥胖(腰围),当5项…
TG 是这些脂蛋白存在的标志,然而降低 TG 的治疗不一定能给糖尿病患者带来心血管益处,这可能是由于 LDL-C 和载脂蛋白 B 水平的增加抵消了降低 TG 带来的益处。 因此,未来旨在降低 TG 的试验中应同时减少 RC、非 HDL-C 和载脂蛋白 B。...
HDL is usually requested with other tests, either with cholesterol or as part of a lipid profile, including LDL and triglycerides. The combination of total cholesterol and HDL is very useful for screening for the risk of heart disease.
The key difference between HDL and LDL cholesterol is that HDL cholesterol is good cholesterol since they carry LDL cholesterol back from arteries to the l
When that LDL leaves your liver, any cell that needs it can claim it. Your liver can produce about 1,000 mg of cholesterol a day, so this stuff is always present [source: Gordon]. To reclaim unused LDLs, your liver bundles cholesterol into HDLs, which pass through you...
