Abstract: A shell, a battery cell, a battery, and an electrical device are provided. The shell includes a circumferential wall and a groove group. The circumferential wall is configured for enclosing an electrode assembly. The groove group includes a plurality of first grooves disposed on the circumferential wall in a circumferential direction of the circumferential wall, and the circumferential wall is configured to crack along the first grooves when pressure or temperature inside the shell reaches a threshold to relieve the pressure inside the shell. The groove group further includes a plurality of second grooves disposed on the circumferential wall in the circumferential direction, the second grooves are alternated with the first grooves in the circumferential direction, and a residual thickness of the circumferential wall at the second groove is greater than that of the circumferential wall at the first groove.

Abstract: A battery module includes a plurality of battery cells and at least one heat exchange tube of an elongated shape. The plurality of battery cells are arranged proximate to each other. Each of the at least one heat exchange tube is located in a gap formed between adjacent ones of the plurality of battery cells.

Abstract: The present application relates to computer-based preoperative planning technology, and discloses a preoperative planning method for multimodal ablation treatment and apparatus thereof, which can automatically provide objective, scientific, and quantitative multimodal ablation planning information. In this method, acquiring parameters of an volume to be ablated; calculating property changes of the tissue caused by performing freezing on the volume according to the parameters of the volume to be ablated, and acquiring a first planning data required for the property changes of the tissue to satisfy a first predetermined condition; further calculating property changes of the tissue caused by performing heating on the volume to acquire a second planning data required for the property changes of the tissue to satisfy a second predetermined condition based on the properties satisfying the first predetermined condition; outputting the first planning data and the second planning data.

Abstract: An apparatus used for increasing the level of CD4+T cells in a mammal. The mammal has a cancerous tissue. The apparatus comprises a cold treatment unit and a heat treatment unit. The cold treatment unit is used for cooling the cancerous tissue. The heat treatment unit is used for heating the cancerous tissue. A method for increasing the level of CD4+ T cells in the body of a cancer patient, comprising steps for cold treatment of the cancerous tissue and for heat treatment of the cancerous tissue.

Abstract: Provided are a tumour immunogen, a preparation method therefore, and an application. After localised sequential cooling-heating treatment is performed on tumour tissue and/or cells, the tumour tissue and/or cells release a large amount of tumour immunogen heat shock protein 70. The obtained tumour immunogen can activate the body's tumour immune system, to convert immunosuppressive cells into mature dendritic cells, thereby increasing immunogen presentation, and activating tumour immunity.
