This invention discloses a traditional Chinese medicine composition for improving diarrhea, belonging to the field of traditional Chinese medicine technology. Addressing the shortcomings of existing antidiarrheal techniques, which only treat the symptoms and not the root cause, have significant side effects, high recurrence rates, and easily cause damage to the intestinal microcirculation, this invention is based on the original microscopic pathogenesis of small intestinal microvascular spasm and ischemia, and abnormal intestinal fluid metabolism. It is prepared by combining peppermint, angelica dahurica, nutmeg, cinnamon, platycodon grandiflorus, and angelica sinensis. The synergistic effect of each herb can target and relax spasmodic small intestinal microvessels, restore normal intestinal blood perfusion, regulate intestinal peristalsis rhythm, bidirectionally regulate intestinal fluid secretion and reabsorption, and simultaneously block abnormal stress signals in the brain-gut axis, repairing intestinal microcirculatory damage. This invention has a scientifically formulated composition, mild medicinal properties, and no side effects. It addresses the root causes of various acute, chronic, and functional diarrheas caused by cold stimulation, emotional stress, and spleen deficiency with cold stagnation, exhibiting strong curative effect and an extremely low recurrence rate, possessing high clinical promotion and application value.

This invention relates to the field of interventional tumor therapy technology and discloses a real-time optimization method for interventional radiotherapy planning. The method includes: dimensionality reduction processing of preoperative three-dimensional angiography images to generate an initial three-dimensional spatial radiation dose distribution matrix; acquisition of in-situ physical and electrophysiological physical quantities corresponding to the injection phase, outputting multimodal synchronous temporal features; analysis of the multimodal synchronous temporal features based on feature decoupling and cross-tissue dielectric cross-validation logic to exclude vasospasm and arteriovenous shunt states, and calculation of dynamic flow resistance increments; reconstruction of blood flow distribution ratios based on dynamic flow resistance increments, accumulating to generate a real-time cumulative radiation dose distribution matrix; monitoring the real-time cumulative radiation dose distribution matrix and catheter reflux pressure gradient, sending a low-level command when a threshold is reached to stop the operation of the radiation-proof high-pressure injection pump. This invention solves the problem of deviation between actual radiation dose distribution and static plan, preventing excessive radiation in non-target areas and microsphere reflux.
