Factor Xa, with Factor Va as a cofactor, turns factor II (also called prothrombin) into factor IIa or thrombin.

活性因子Xa和作为辅因子的因子Va将因子II（血酶原）转变为因子IIa（血酶）。

Finally, an elevated or prolonged prothrombin time, which is the time it takes your blood to clot, is a typical lab finding in more severe cases.

最终，血酶原时间延长，即血固的时间，也是更严重自免肝病例的典型实验室指标。

There is also a prolonged prothrombin (or PT) time, as well as prolonged partial thromboplastin time (or PTT), both of which reflect having lower levels of circulating coagulation factors.

血酶原（PT）时间和部分血活酶（PTT）时间均会延长，两者都反映出血循环中低水平的血因子。

Diagnosis of hemophilia A and B usually starts with lab tests including a platelet count which is usually normal, a prothrombin (PT) time, and a partial thromboplastic (PTT) time.

血友病A和B的诊断通是进行实验检测，包括血小板计数（一般）、血酶原时间（PT），以及部分血活酶时间（PTT）。

Also, disseminated intravascular coagulation, or DIC, is also a possible complication, since the decidua basalis layer is also rich in thromboplastin, so an abruption causes the release of large quantities of thromboplastin which causes widespread clotting.

还有弥散性血管内血（DIC）也是并发症之一，由于基蜕膜层内富含促血酶原激酶，所以胎盘剥离导致促血酶原激酶大量释放，从而导致广泛的血。

Plasma is the liquid part of the blood and consists of water, dissolved proteins, sugar, salts, hormones, and other substances. The four major plasma proteins are albumin, globulin, fibrinogen, and prothrombin.

血浆是血的体部分，由水，溶解的蛋白质，糖，盐，激素和其他物质组成。四种主要的血浆蛋白是白蛋白，球蛋白，纤维蛋白原和血酶原。
