The invention is applied to the technical field of medical apparatus and instruments and discloses a vena cava filter. The vena cava filter can be temporarily or permanently placed in blood vessels for capturing thrombus and preventing pulmonary artery embolism. The vena cava filter comprises a blood vessel wall fixer for supporting in the blood vessels and a thrombus filter for capturing the thrombus; a fixing structure for positioning and fixing a supporting position of the blood vessel wall fixer is arranged on the blood vessel wall fixer; the thrombus filter is connected onto the blood vessel wall fixer; a releasing / recovering device for being connected with a control machine is arranged on the thrombus filter and / or the blood vessel wall fixer. The vena cava filter provided by the invention has the advantages of small contact area between the vena cava filter and blood vessel walls, convenience in operation, high capturing rate of the thrombus and long recovery time; the reliability and the safety of vena cava filter use are improved.

The invention discloses fritillaria superfine powder as well as a preparation method and application thereof. The preparation method comprises the following steps: step 1, selecting materials and cleaning; step 2, drying and sterilizing; step 3, grinding and pulping; step 4, pre-freezing slurry; step 5, freezing and drying; step 6, smashing for multiple times into the fritillaria superfine powder with a grain size of 0.5-2 [mu]m. The fritillaria superfine powder is prepared by the preparation method. The fritillaria superfine powder prepared by the preparation method is taken as an only active ingredient to be applied to the preparation of a drug for treating a pulmonary disease. The fritillaria superfine powder disclosed by the invention is used for treating pneumothorax, pulmonary bullous, emphysema, pulmonary shadow, lung cancer, pulmonary heart disease, respiratory failure, pulmonary embolism, pulmonary abscess, pneumonia, neonatal pneumonia, infantile pneumonia, trachitis, asthma, pulmonary tuberculosis, pneumoconiosis and / or interstitial lung disease and has the advantages that the treatment effect is obvious, the condition of a patient is stable, the life quality of the patient is improved, the weight of the patient is increased, the immune function of the patient is improved, and the medication is safe.

Disclosed are crystalline forms A, B and C of 1 ,2-Pyrrolidinedicarboxamide, N1 -(4- chlorophenyl)-N2-[2-fluoro-4-(2-oxo-1 (2H)-pyridinyl)phenye]-4-methoxy-, (2R,4R)- (9Cl). These crystalline forms a re characterized by their powder X-ray diffraction, solid-state NMR, as well as methods for the preparation and pharmaceutical compositions of the same which are useful for the treatment of acute, subacute, or chronic thrombotic disorders including treatment of venous thrombosis, arterial thrombosis, pulmonary embolism, myocardial infarction, cerebral infarction, restenosis, atherosclerosis, angina, primary and secondary deep vein thrombosis, thromboembolism associated with cardiovascular disease, including, but not limited to, acute coronary syndrome, atrial fibrillation, cardiac valve replacement and deep vein thrombosis. The crystalline forms of the present invention are also useful for the treatment of cancer, sepsis and diabetes.
