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 invention relates to the use of a pharmaceutical medication comprising an aromatase inhibitor, preferably a steroidal aromatase inactivator and an antioxidant as effective ingredients for the treatment of sex hormone-dependent diseases. Furthermore, the invention relates to a composition comprising an aromatase inhibitor / —inactivator and α-lipoic acid and / or extract of green tea containing polyphenols. The combination of an aromatase inhibitor and—inactivator and α-lipoic acid and / or extract of green tea containing polyphenols is particularly suitable for the treatment of sex hormone-dependent diseases as well as for the treatment of benign tumors such as e.g. lipomatoses as occurring in Madelung's disease.

Metal proteins on the surfaces of the pathogenic microorganisms have high-density zinc ions, and the zinc ions are beneficial for the pathogenic microorganisms to be attached to metal ions on the metal proteins on the surfaces of host cells (similar to that the zinc ions are found in a battery and form a zinc-other metal electrode pair with other metal ions). The pathogenic microorganisms and fragments thereof release zinc-rich products into the host body, and the zinc-rich products rapidly enable chelating agents (mainly derivatives of polyamine / aminopolycarboxylic acid) with the property of binding zinc ions to be completely bound with the zinc ions, so that the active chelating agents are consumed. When the active chelating agent is used up, the zinc-rich product is combined with the host metal protein to cause most symptoms, then a new active chelating agent is generated in the host, the zinc-rich product is separated from the host metal protein, and most symptoms are eliminated. The medicament according to the invention comprises a chelating agent (polyamine / aminopolycarboxylic acid derivative) with strong zinc ion binding properties, having the following effects:-rapid alleviation of the majority of symptoms; -attenuating the microorganism and making it out of its ability to bind to the host cell; -enhancing the immune system of the host; -clearance of zinc-rich products accumulated in host metalloproteins, eliminating the majority of symptoms; -a post-disease syndrome; -and the like. The medicine provided by the invention contains a high-activity chelating agent and a medicament (in a treated tissue) capable of generating a strong physical effect, is used for treating diseased tissues (such as bacterial infection tissues / necrotic tissues / fungal infection tissues / benign tumors / cancerous tumors), and has a remarkable curative effect.

The invention provides a culture medium and a culture method of normal oral fibroblasts. The culture medium comprises a DMEM (Dulbecco's Modified Eagle Medium) and the following components based on the volume of the DMEM: 10v% of Australian fetal calf serum, 2.5 ng / ml of bFGF (Basic Fibroblast Growth Factor), 1v% of a penicillin-streptomycin solution, 2.0 ug / ml of hydrocortisone and 0.05 ug / ml of FGF10 (Fibroblast Growth Factor 10). The invention solves the problems of high NF culture difficulty, easy pollution, low survival rate, incapability of permanent passage and the like, provides a basis for further exploring a mechanism for activating the NF into CAFs, is beneficial to finding and finding new therapeutic targets, and provides a new clinical diagnosis and treatment idea for treating and preventing the deterioration of the salivary gland benign tumor.

The invention relates to the technical field of image recognition, and discloses a breast ultrasonic tumor recognition method fusing channel attention and dynamic channel routing, which comprises the following steps: acquiring a breast ultrasonic image, and carrying out preprocessing and data enhancement; constructing a deep convolutional neural network containing a ResNet101 backbone network, an SE channel attention unit and a dynamic feature reconstruction module; taking Focal Loss with category weight as a loss function, and combining with an SAM optimizer to train the network; according to the method, an SE channel attention unit is embedded, a dynamic feature reconstruction module is connected, and an SAM optimizer is cooperatively used, so that the model can model channel importance and global space context dependence at the same time, and the classification probability of a benign tumor, a malignant tumor or a normal tissue is output. And a flat minimum value is found on a complex loss curved surface, so that accurate and robust recognition of tumors in low-quality and small-sample breast ultrasound images is realized, and the classification accuracy and generalization ability are effectively improved.

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.
