Abstract: Embodiments of this application provide a method for detecting a connection to a headset port of an electronic device, an electronic device, and a readable storage medium. When a headset component is connected to the headset port of the electronic device, if it is detected that the electronic device does not have a function of performing conversion between digital audio and analog audio and that the headset component connected to the headset port of the electronic device is an analog component, it is determined that the headset port cannot support the connected headset component. In this way, an electronic device omitting a codec can determine that an analog headset cannot be used.

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.
