研究目的: |
脑血管疾病是全球范围内导致死亡的主要原因之一,而低密度脂蛋白(LDL-C)水平的升高是脑血管疾病的关键危险因素。传统的降脂药物在降低LDL-C方面取得了显著效果,但它们存在一定的副作用和禁忌症。因此,寻找一种安全、有效的替代疗法对于脑血管疾病的防治具有重要意义。抗性淀粉是一种益生元纤维,由结肠中的共生细菌代谢产生短链脂肪酸(SCFA),包括乙酸、丙酸和丁酸,有研究已证实益生元纤维和SCFAs可预防高血压的发展。HamdiaA等研究表明,随机分配到安慰剂组的参与者具有更高的基线高密度脂蛋白(HDL)胆固醇(P = 0.02)和低密度脂蛋白(LDL)胆固醇(P = 0.04)和甘油三酯(P = 0.03)。前期研究也表明,改性淀粉可以通过与肠道菌群相互作用,调节脂质代谢,从而降低血液中的LDL-C水平。本研究的目的是确定改性淀粉是可以通过调节肠道菌群和释放高水平SCFAs来降参与者的低密度脂蛋白水平。 |

Objectives of Study: |
Cerebrovascular diseases are one of the leading causes of death globally. Elevated levels of low - density lipoprotein cholesterol (LDL - C) are a key risk factor for cerebrovascular diseases. Traditional lipid - lowering drugs have achieved remarkable results in reducing LDL - C, but they have certain side effects and contraindications. Therefore, finding a safe and effective alternative therapy is of great significance for the prevention and treatment of cerebrovascular diseases. Resistant starch is a prebiotic fiber that is metabolized by symbiotic bacteria in the colon to produce short - chain fatty acids (SCFAs), including acetic acid, propionic acid, and butyric acid. Studies have confirmed that prebiotic fibers and SCFAs can prevent the development of hypertension. A study by Hamdia A et al. showed that participants in the placebo group had higher baseline high - density lipoprotein (HDL) cholesterol (P = 0.02), low - density lipoprotein (LDL) cholesterol (P = 0.04), and triglycerides (P = 0.03). Previous studies have also indicated that modified starch can interact with the gut microbiota to regulate lipid metabolism, thereby reducing LDL - C levels in the blood. The purpose of this study is to determine whether modified starch can reduce participants' LDL - C levels by regulating the gut microbiota and releasing high levels of SCFAs. |
