  • Publication number: 20250143785
    Abstract: A scalpel includes a blade and a handle, where the blade includes an outer blade, an inner blade, and a sheath. A distal end of the outer blade and a distal end of the inner blade are sequentially arranged from a distal end to a proximal end of the blade. The outer blade, the inner blade and the sheath are coaxial. The inner blade and the outer blade are configured to be capable of moving relatively in an axial direction or rotating relatively around a central axis. The inner blade includes an electrode. The electrode is connected to a radiofrequency generation apparatus. The electrode covers a cross-section of the distal end of the inner blade or covers a non-radial cross-sectional groove edge of an inner blade groove. The interior of the inner blade or an inner channel of the inner blade can be connected to a negative pressure apparatus.

  • Patent number: 12175669
    Abstract: The present disclosure provides a method and an apparatus for acquiring a contour line of a blood vessel according to a centerline of the blood vessel. The method comprises: extracting a centerline of a blood vessel according to a two-dimensional coronary artery angiogram image (S100); obtaining an image of a straightened blood vessel according to the centerline of the blood vessel (S200); setting a threshold Dthreshold for a diameter of the blood vessel on the image of the straightened blood vessel (S300); generating a preset contour line of the blood vessel on both sides of a centerline of the straightened blood vessel according to the Dthreshold (S400); making the preset contour line of the blood vessel step-by-step approach the centerline of the straightened blood vessel to acquire a contour line of the straightened blood vessel (S500); projecting the contour line of the straightened blood vessel back onto the image of the centerline of the blood vessel to obtain a contour line of the blood vessel (S600).

  • Publication number: 20230139025
    Abstract: An antioxidant for use in treatment for a radiation-induced bystander effect to a transplanted cell in a host is provided. The antioxidant is N-acetyl-L-cysteine, sulforaphane or resveratrol, or a combination thereof. The RIBE on transplanted human hematopoietic cells impaired the long-term hematopoietic reconstitution of human HSCs as well as the colony-forming ability of HPCs, and the RIBE-affected human hematopoietic cells showed enhanced DNA damage responses, cell cycle arrest and p53-dependent apoptosis, mainly due to oxidative stress. Taken together, these findings suggest that RIBE impairs human HSCs by oxidative DNA damage. The present disclosure provides definitive evidence for RIBE in transplanted human HSCs and further justifies the necessity for conducting clinical trials to assess the ability of multiple antioxidants to improve the efficacy of HSC transplantation for patients with hematological or non-hematological disorders.
