Aiming at the conditions that heparin has severe bleeding side effects in clinical practice and clinical application thereof is restricted, the invention discloses a technique for producing ultra-low molecular heparin sodium (calcium). The technique comprises the following steps of: taking heparin sodium solution, adding sodium nitrite solution for cracking; adjusting the lysis buffer by using alkaline; absorbing impurities by using an anion-exchange column; washing for obtaining ultra-low molecular heparin calcium; carrying out filtration by using an ultrafiltration membrane and obtaining a precipitate by using alcohol; and after desalting, dehydration, re-precipitation, cooling and drying, obtaining a finished product of ultra-low molecular heparin calcium. The product has better and safer antithrombotic effect under low level of anticoagulation, and can be widely used for preventing and treating diseases such as deep vein thrombosis, pulmonary embolism, disseminated intravascular coagulation, and the like.

This invention relates to novel antibodies that bind with greater affinity to the factor VIIa/tissue factor (FVIIa/TF) complex than to tissue factor (TF) alone, do not compete for binding to TF with FVII and FX, an inhibit FX activation.

The antibodies can be used to treat a variety of thrombotic conditions including but not limited to deep vein thrombosis, disseminated intravascular coagulation, and acute coronary syndrome.

In one aspect, the invention provides methods of inhibiting the effects of MASP-2-dependent complement activation in a living subject. In one embodiment, the invention provides methods of treating a subject suffering from a complement mediated coagulation disorder, such as disseminated intravascular coagulation. The methods comprise the step of administering, to a subject in need thereof, an amount of a MASP-2 inhibitory agent effective to inhibit MASP-2-dependent complement activation. In some embodiments, the MASP-2 inhibitory agent inhibits cellular injury associated with MASP-2-mediated alternative complement pathway activation, while leaving the classical (C1q-dependent) pathway component of the immune system intact. In another aspect, the invention provides compositions for inhibiting the effects of lectin-dependent complement activation, comprising a therapeutically effective amount of a MASP-2 inhibitory agent and a pharmaceutically acceptable carrier.

A method is disclosed for predicting the presence of haemostatic dysfunction. At least one time-dependent measurement on an unknown sample is performed and a respective property of the sample is measured over time so as to derive a time-dependent measurement profile. One or more predictor variables, including initial slope, are defined which sufficiently define the data of the time-dependent measurement profile. A model is then derived that represents the relationship between the abnormality and the set of predictor variables. Subsequently, the model is utilized to predict haemostatic dysfunction, such as septicemia or disseminated intravascular coagulation (DIC).

The fusion protein binds at the site of injury and prevents the initiation of thrombosis. The fusion protein can be used to treat a variety of thrombotic conditions including but not limited to deep vein thrombosis, disseminated intravascular coagulation, and acute coronary syndrome.
