中草药改善糖尿病性勃起功能障碍?

糖尿病性勃起功能障碍(DIED)被认为是糖尿病(DM)的常见并发症之一。其发病机制可能与神经、血管、血管内皮、内分泌等因素有关。

糖尿病性勃起功能障碍(DIED)被认为是糖尿病(DM)的常见并发症之一。其发病机制可能与神经、血管、血管内皮、内分泌等因素有关。流行病学调查显示,在当今社会,男性DM患者勃起功能障碍(ED)的发生率已达到35%~90%,是非男性勃起功能障碍(ED)的1.9~4倍。由于DM本身引起的各种复杂的血管和神经病变,死亡比普通ED更难治疗。目前,血管内皮功能障碍和血小板活化异常已被证明是DIED的重要机制,上述机制被认为与中医所说的活血阻络相似。同时活血化瘀中药可在一定程度上改善高血糖时血管内皮功能。但活血化瘀中药对DIED血管内皮功能影响的研究较少。

蛋白激酶C (PKC)信号通路作为重要的细胞内信号转导通路,在细胞凋亡、神经兴奋性、细胞增殖分化、基因表达和细胞坏死等方面发挥着关键作用。活血通络七味汤的主要作用是活血通络、散瘀止风。这种治疗可以有效改善ED患者的症状,对DIED患者有很好的治疗效果。为进一步探讨活血通络七味汤治疗DIED的作用机制,设计了相关的动物实验。链脲佐菌素(STZ)诱导大鼠模型,阿扑吗啡(APO)筛选。活血通络七味汤对勃起状态、血管内皮损伤标志物、内皮细胞超微结构、甘油二酯蛋白及mRNA表达的影响 (DAG)、PKCβ、核转录因子(NF-κB)、细胞间黏附分子-1(ICAM-1) 观察 DIED 大鼠,探讨活血通络七味汤改善 DIED 的机制。

材料和方法:采用高效液相色谱-串联质谱法(HPLC-MS/MS)对活血通络七味汤的化学成分进行了鉴定。链脲佐菌素(STZ)诱导大鼠模型,阿扑吗啡(APO)筛选。通过酶联免疫吸附试验(ELISA)研究血清sE-选择素、赖氨酰氧化酶-1(LOX-1)、丙二醛(MDA)等血管内皮损伤标志物及氧化应激相关指标。通过电子显微镜和HE染色检查海绵体的内皮细胞和超微结构。Western blotting检测蛋白和mRNA的表达 (WB) 和实时定量聚合酶链反应 (RT-qPCR)。

研究结果显示,M组大鼠血清中sE-选择素、LOX-1、细胞间粘附分子-1(sICAM-1)、内皮微粒(EMPs)、P-选择素(CD62P)和MDA水平显着高于K组大鼠,而超氧化物歧化酶(SOD)水平显着下降。此外,PKC通路被激活,相关蛋白和mRNA的表达增加。活血通络七味汤和LY333531干预8周后L、D、G组血清sE-选择素、LOX-1、sICAM-1、EMPs、CD62P、MDA水平显着低于M组,SOD水平显着升高,蛋白激酶C(PKC)通路受到抑制改善大鼠的勃起功能。

基于 HPLC-MS/MS 的活血通络芪味汤正离子色谱分析:

 

综上所述,发现 DIED 的机制与血管内皮损伤和 PKCβ 信号通路激活引起的异常血小板激活有关。活血通络七味汤可抑制 DIED 大鼠 PKCβ 信号通路相关分子的蛋白和 mRNA 表达,促进血管内皮损伤,增强抗氧化能力,阻止血小板活化,从而改善 DIED 大鼠的勃起功能。
