The invention relates to a method for preparing a medicament for treating leucopenia. The preparation method comprises the following steps of: taking medicinal materials in a ratio, adding 60 to 80 percent ethanol in an amount which is 6 to 10 times the weight of the medicinal materials, performing reflux extraction for 2 to 4 times and 1 to 3 hours every time, combining the ethanol extracts, and recovering the ethanol till the ethanol smell does not exist to obtain paste; decocting the medicinal residue for 2 to 4 hours and 1 to 3 hours every time by adding water in an amount which is 4 to 6 times the weight of the medicinal residue, combining the decoction, and concentrating; and combining the medicinal paste, concentrating the medicinal paste into thick paste under reduced pressure, adding available medicinal accessories into the thick paste, thus obtaining a clinical available preparation. The medicament has the effects of nourishing liver and kidney and tonifying qi and blood, and is clinically used for treating the leucopenia produced after malignant tumor radiotherapy and chemotherapy.

The invention relates to a glioblastoma multiforme targeting nano magnetic resonance contrast agent as well as preparation and application thereof. The magnetic resonance contrast agent consists of asmall molecule with a targeting combination function, a fluorescence indicator and a magnetic iron oxide nano carrier, wherein the small molecule with the targeting combination function is oligopeptide which has affinity with EGFRvIII which is highly expressed on the surface of a glioblastoma multiforme cell; the surface of the nano carrier is coated by the fluorescence indicator in a covalent linkage manner; the oligopeptide is connected with polyethylene glycol on surfaces of nanoparticles in the covalent linkage manner. The contrast agent can be administrated in an intravenous injection manner, the oligopeptide is combined with EGFRvIII which is highly expressed on the surface of a tumor cell, concentrated accumulation of the nano carrier at a tumor part is promoted, clinical treatmentprecision and security can be improved, and a noninvasive visible means are provided for treatment effect evaluation of tumor chemoradiotherapy and prognosis evaluation on patients.
