The invention relates to the technical field of craniocerebral injury biomechanical analysis, discloses a semi-automatic craniocerebral injury index CSDM extraction method, and aims to improve CSDM extraction efficiency, applicability and flexibility. The method comprises the following steps: a brain tissue area display state pre-selection step: importing a head model simulation result file into post-processing software, screening and retaining brain tissue entity unit components, hiding irrelevant components and recording parameters; a strain and volume frame-by-frame output step: compiling an automatic script based on a post-processing software secondary development function to realize frame-by-frame output of unit data; and an automatic operation step: automatically calculating the CSDM value of each frame based on the output file through a Matlab calculation program. According to the method, the problems that manual extraction is low in efficiency and prone to errors and a full-automatic method is poor in universality are solved through a manual preprocessing and automatic calculation fusion mode, and the method is suitable for various head models and supports craniocerebral injury mechanism research and clinical assistance.

A method for microwave-assisted extraction of blue indigo mud from Strobilanthes cusia belongs to the field of natural dye preparation. The method comprises the following steps: 1) mixing fresh Strobilanthes cusia leaves with water according to a specific solid-liquid ratio, and performing microwave-assisted treatment to make the indigo precursor quickly dissolve out; 2) after the extraction liquid is cooled by standing, an alkali agent is added for oxidation precipitation, and after solid-liquid separation and drying, the blue indigo mud with high indigo content is obtained. The indigo yield of the present application can reach 0.32%~0.42%, and the purity of indigo in the product is stable at more than 80%, and the highest can reach 87.49%. The method realizes efficient and rapid extraction of indigo from Strobilanthes cusia, significantly shortens the time of traditional indigo preparation process, and is simple, environment-friendly, stable in product quality, and suitable for industrial production.
