Increased glutamate in type 2 diabetes in the Korean population is associated with increased plasminogen levels. [PDF]

open access: yesJ Diabetes, 2023
Highlights Increased glutamate is associated with the development of diabetes. Glutamate increases plasminogen (PLG) levels through glutamate metabotropic receptor 5 activation with various insulin resistance‐related stresses. Glutamate inhibits the conversion of PLG to plasmin by increasing plasminogen activator inhibitor‐1.

长春地区血浆凝血酶激活纤溶抑制物参考区间的建立

open access: yesZhongguo shiyan zhenduanxue, 2022
<正>凝血酶激活纤溶抑制物(TAFI)是一种由肝脏合成的,具有羧肽酶活性的单链糖蛋白,分子量60kD,于1989年被Hendrik等发现及报道[1]。TAFI以酶原的形式存在于血浆中,可被凝血酶、纤溶酶、凝血酶-血栓调节蛋白等物质激活,激活的TAFI具有内在的不稳定性。1995年Bajzar等人发现TAFI可使凝血块的纤溶时间延长,

肝移植围术期纤溶酶活性及α2-抗纤溶酶活性变化

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2006
【目的】观察肝移植围术期纤溶酶活性及α2-抗纤溶酶活性的变化。【方法】19例患者分为重型肝炎组(H组,8例)与肝肿瘤组(N组,11例),接受原位肝移植术,均未采用体外静脉-静脉转流。两组患者分别于术前(T0)、手术1h(T1)、无肝10min(T2)、新肝5min(T3)、关腹前30min(T4),5个时间点,抽取动脉血测定纤溶酶活性及α2-抗纤溶酶活性,并记录各时段促凝抗纤溶药物的用量。【结果】两组患者纤溶酶活性在T2、T3和T4与T0比较明显增强(P〈0.05);α2-抗纤溶酶活性在T1 ...
