项目摘要
We evaluated 42 patients with type B acute aortic dissection (AD), andserum TN-C levels significantly increased at 7 days and then gradually decreased to normal range at 28 days. Serum TN-C levels at 7 days correlated positively with peak C-reactive protein levels, FDP levels, D-dimer levels, and maximum aortic diameter at the dissection level on admission. Serum TN-C levels of 3 dead patients on admission were significantly higher than those of surviving patients. Serum TN-C levels were significantly elevated during acute stage and might be a novel biomarker to predict patient prognosis of type B acute AD.In mouse model, TN-C was highly expressed in the medial layer of the dissected aortic wall, andwas concordant with the area of the vascular smooth muscle cells (VSMCs) stained by α-SMA. In the TN-C reporter mouse knock-in with LacZ, the medial layer of the dissected aortic wall was stained by the β-gal, and furthermore αSMA-positive cells were also positive in β-gal. We found that the producing cells of TN-C were VSMCs in the dissected aortic wall.
我们评估了 42 名 B 型急性主动脉夹层 (AD) 患者,血清 TN-C 水平在第 7 天显着升高,然后在第 28 天逐渐下降至正常范围,第 7 天血清 TN-C 水平与峰值 C 反应呈正相关。 3例死亡患者入院时血清TN-C水平、FDP水平、D-二聚体水平和最大主动脉直径均显着高于存活患者。 TN-C水平在急性期显着升高,可能是预测B型急性AD患者预后的新生物标志物。在小鼠模型中,TN-C在解剖主动脉壁的内层高表达,并且与α-SMA 染色的血管平滑肌细胞 (VSMC) 区域 在用 LacZ 敲入的 TN-C 报告小鼠中,解剖的主动脉壁的内侧层被 α-SMA 染色。 β-gal,而且αSMA阳性细胞在β-gal中也呈阳性。我们发现,TN-C的产生细胞是解剖的主动脉壁中的VSMC。
