Evaluate the Effectiveness and Safety of Raman IVD Analyzer in the Molecular Diagnosis of Gliomas During Surgery

Inclusion Criteria:

* Patients who plan to undergo brain lesion tissue resection surgery or have preoperative clinical diagnosis of gliomas and plan to undergo biopsy;
* Patients with clinical diagnosis of initial solitary gliomas, or initial solitary intracranial masses or initial non occupying lesions that do not exclude gliomas (such as intracranial metastatic lesions, intracranial infectious lesions, intracranial demyelinating lesions, central nervous system lymphoma, etc.), who have not received radiotherapy or chemotherapy in the past based on their medical history;
* The patient or their guardian can understand the research purpose, demonstrate sufficient compliance with the trial protocol, consent for immunohistochemistry or genetic test, and sign an informed consent form;
* It is possible to obtain tissue samples with a length diameter greater than 0.2cm. Patients diagnosed with initial solitary glioma should take core or marginal tissue, while patients diagnosed with initial single intracranial mass or initial non mass lesions but maybe with gliomas should be taken core tissue.
