This invention discloses a methylation marker for the differential diagnosis of malignant and benign breast tumors. The invention provides the application of the methylated SH3PXD2B gene as a marker in product preparation; the product is used for at least one of the following purposes: (1) distinguishing between benign and malignant breast tumors; (2) distinguishing between benign breast tumors and different subtypes or stages of malignant breast tumors; (3) distinguishing between different subtypes or stages of malignant breast tumors. This invention has significant scientific and clinical application value for differentiating between benign and malignant breast tumors, different subtypes or stages of malignant breast tumors, and guiding the development of reasonable clinical treatment plans.

This utility model discloses a bipolar radiofrequency electrode for bone tumor surgery, which includes a cable assembly, a handle, a scalpel, and a scalpel head connected in sequence. The scalpel head includes a suction tube and an outer steel tube that is spaced and sleeved on the suction tube, with a water outlet channel formed between the suction tube and the outer steel tube. The scalpel head includes an insulating head fixed to the distal end of the outer steel tube. The insulating head is provided with a first strip electrode and a second strip electrode arranged side by side. The insulating head located at the first strip electrode and the second strip electrode has several suction holes, which are connected to the suction tube. Several water outlet holes connected to the water outlet channel are provided on both sides of the distal end of the outer steel tube. This solution uses radiofrequency electrodes to irrigate the incision after the resection of benign spinal tumors, which can accurately stop bleeding at soft tissue bleeding points, effectively reducing the amount of bleeding. Furthermore, by utilizing the circulating supply of physiological saline, the first strip electrode and the second strip electrode are effectively wrapped by physiological saline, thereby ensuring the plasma excitation efficiency.

The present invention relates anti-microbial antibody signatures related to lung tumors, including benign tumors and adenocarcinomas. Disclosed herein are antibody panels comprising antigens from bacteria and / or viruses for use in early and accurate diagnosis of lung cancer and for reducing false positive lung carcinoma diagnoses from CT screening.

Devices, systems and methods are provided to treat damaged, diseased, abnormal, obstructive, cancerous or undesired tissue (e.g. a tumor, a benign tumor, a malignant tumor, a cyst, or an area of diseased tissue, etc) by delivering specialized pulsed electric field (PEF) energy to target tissue areas. The energy is delivered in a manner so as to be non-thermal (i.e. below a threshold for causing thermal ablation). Consequently, when extracellular matrices present, the extracellular matrices are preserved, and the targeted tissue maintains its structural architecture including blood vessels and lymphatics. Thus, sensitive structures, such as biological lumens, blood vessels, nerves, etc, are preserved which are critical to maintaining the integrity and functionality of the tissue. The energy is delivered with the use of systems and devices advantageously designed for superior access to target tissue throughout the body, particularly in locations previously considered inaccessible to percutaneous approaches.
