生姜有效部位对实验性高脂血症大鼠血管内皮的保护作用

目的:观察生姜有效部位(EPZ)对高脂血症大鼠血管内皮形态学改变及血清白细胞介素6(IL-6)、肿瘤坏死因子α(TNF-α)的影响,探讨其保护血管内皮的机制。方法:以高脂饲料喂养大鼠,造成高脂血症模型,同时每天灌服生姜有效部位(主要成分为姜辣素及挥发油)200 mg/kg、400 mg/kg、800 mg/kg,连续13 w。取血,放射免疫法测定血清中IL-6、TNF-α的水平。分离并剪取胸主动脉和腹主动脉观察其血管内皮形态的改变,并测定主动脉内膜中膜厚度(IMT)。结果:生姜有效部位能显著改善高脂血症造成的血管内皮损伤,降低IMT,但对血清中IL-6、TNF-α无显著影响。结论:生姜有效部位能保护血管内皮细胞,但未能明显影响血清炎症因子IL-6、TNF-α的水平。

Silencing of Nesprin‐2 inhibits the differentiation of myofibroblasts from fibroblasts induced by mechanical stretch

Mechanical force plays a pivotal role in the pathogenesis of hypertrophic scar (HTS). Dermal fibroblasts and myofibroblasts are the key cells involved in HTS. Myofibroblasts in HTS possess different biochemical and biophysical characteristics by which myofibroblasts are often distinguished from fibroblasts. The role of mechanotransducers outside the nucleus in the pathogenesis of HTS has been reported in many studies. However, the role of Nesprin‐2 in HTS is not clear. Hence, we aim to construct a cell model of HTS and explore the role of Nesprin‐2 in this process. Myofibroblasts and fibroblasts were isolated from HTS and healthy skin tissues of the same patient. Fibroblasts were exposed to cyclic stretch with 10% magnitude and a frequency of 0.1 Hz for 3 days, 5 days, and 7 days, respectively. After the cell model was confirmed, fibroblasts transfected with siRNA targeting human Nesprin‐2 were exposed to cyclic stretch. The mechanical behaviour and biochemical reaction of the dermal fibroblasts were analysed. The stretched fibroblasts at day 5 showed the same mechanotransductive and biochemical features as unstretched myofibroblasts. Mechanical strain could induce the myofibroblasts differentiation and a cell model of HTS was established successfully at day 5. The expressions of lamin A/C, alpha‐smooth muscle actin, transforming growth factor beta 1, and collagen type I in fibroblasts were reduced by the silencing of Nesprin‐2. Mechanical strain could induce the myofibroblasts differentiation and silencing of Nesprin‐2 could block the mechanical stimulation of terminal myofibroblasts differentiation. Nesprin‐2 might be a potential target to treat the HTS.     

腺苷酸活化蛋白激酶在牙周病发生发展中的研究进展

牙周病是以特殊致病菌和破坏性免疫反应相互作用导致的牙周支持组织病理性吸收为特征。腺苷酸活化蛋白激酶（AMPK）作为关键的能量调节因子,通过参与调节重要组织器官脂肪酸和葡萄糖的代谢,从而维持身体内环境的稳态,在代谢性疾病中已被广泛研究。AMPK也可以通过参与牙周骨代谢、免疫反应、基质金属蛋白酶的分泌以及细胞自噬的调节来调控牙周病的发生和发展,在牙周病发病机制中具有潜在作用,并为牙周病的治疗提供了新的治疗靶点。本文对AMPK及其在牙周病发病机制中的研究进展做一综述。
