Abstract: The present disclosure provides use of Clostridium ghonii combined with a tumor angiogenesis inhibitor in preparing a pharmaceutical product for treating a tumor. The present disclosure further provides a drug for treating a tumor, where the drug includes active ingredients of Clostridium ghonii and a tumor angiogenesis inhibitor.

Abstract: The present disclosure relates to use of a Clostridium ghonii spore combined with pembrolizumab in cancer treatment. It is found for the first time that the Clostridium ghonii spore combined with pembrolizumab can significantly improve a curative effect of colon cancer and reduce a dose of the pembrolizumab, and thus is efficient and low-toxic. Oncolysis by Clostridium ghonii can affect immunogenicity of a tumor microenvironment (TME) by various ways, converts an immunosuppressive state of the TME into an immune-activated state, adjusts the immunosuppressive TME, and breaks an immune tolerance. An optimal combination of the Clostridium ghonii spore and the pembrolizumab thoroughly removes about 20% of mouse tumor tissues. A benefit range of patients with tumors treated by a PD-1 antibody is expanded. The combination even has an obvious curative effect on patients failed the treatment by the PD-1 antibody.

Abstract: A super-flexible high thermal conductive graphene film and a preparation method thereof are provided. The graphene film is obtained from ultra large homogeneous graphene sheets through processes of solution film-forming, chemical reduction, high temperature reduction, high pressure suppression and so on. The graphene film has a density in a range of 1.93 to 2.11 g/cm3, is formed by overlapping planar oriented graphene sheets with an average size of more than 100 ?m with each other through ?-? conjugate action, and comprises 1 to 4 layers of graphene sheets which have few defects. The graphene film can be repeatedly bent for 1200 times or more, with elongation at break of 12-18%, electric conductivity of 8000-10600 S/cm, thermal conductivity of 1800-2600 W/mK, and can be used as a highly flexible thermal conductive device.
