复星 (RES) 与基于证据的护理相结合,通过改善代谢健康和心脏功能,可以预防糖尿病心肌病 (DCM). 这种干预通过SIRT1/PPAR-α/PGC-1通路针对氧化应激和亡.
科学领域:
- 心脏病学 心脏病学
- 内分泌学 在内分泌学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 糖尿病心肌病 (DCM) 是2型糖尿病 (T2DM) 中的主要心血管并发症.
- 现有的DCM治疗方法存在局限性,需要新的治疗策略.
- 复星 (RES) 显示出潜在的心脏保护作用,但其与护理干预措施的结合需要进一步调查.
研究的目的:
- 调查复星 (RES) 结合基于证据的护理对T2DM的老年患者糖尿病心肌病 (DCM) 的保护作用.
- 用动物和细胞模型阐明 RES 改善 DCM 的潜在分子机制.
- 评估联合干预对临床指标和心脏功能的影响.
主要方法:
- 80名患有DCM的老年T2DM患者被随机分配到对照组 (安慰剂+护理) 或RES组 (RES800 mg/天+护理) 六个月.
- 使用T2DM大鼠模型来评估心肌保护,氧化应激,亡,自和纤维化.
- 使用高葡萄糖 (HG) 诱导的H9C2心肌细胞来探索涉及SIRT1/PPAR-α/PGC-1通路的细胞机制.
主要成果:
- RES组显示葡萄糖和脂质代谢改善,乳酸脱酶 (LDH) 活性降低,炎症标志物 (TNF-α,IL-6) 降低.

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
888
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Pathophysiology of Diabetes
3.1K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
