This invention proposes an intelligent segmentation method for reticular fiber stained pathological images and its application. Addressing the limitations of existing technologies in identifying reticular fiber structure disruptions to define tumor boundaries and artifacts caused by sliding windows, this invention employs adaptive sliding window segmentation and multi-stage pre-filtering to extract effective image blocks. The input is a dual-stream network, where structural and visual flows are fused through cross-attention based on tissue physical size mapping receptive fields to achieve collaborative verification of visual abnormalities and structural disruptions. Model training utilizes a dynamic boundary-aware loss term with physical scale constraints for joint optimization. Finally, a spatial weight fusion mechanism combined with a graph model incorporating physical priors eliminates breakage artifacts and smooths global boundaries. This invention is primarily used for high-fidelity lesion segmentation of pituitary neuroendocrine tumors.

The present invention belongs to the field of medicine and discloses the use of a CSF1R inhibitor in preparing a drug for treating or alleviating myelofibrosis. At the same time, the present invention also discloses a drug for treating or alleviating myelofibrosis. ‑ / ‑ miR‑146a ‑ / ‑ A del(5q) MDS mouse model constructed by DKO mice was established. Treatment with the CSF1R inhibitor PLX3397 demonstrated the following positive effects: PLX3397 alleviated anemia in DKO mice, significantly reduced the number of fibrocytes in their peripheral blood and spleen, and decreased reticular and collagen fiber deposition in the bone marrow, effectively improving myelofibrosis. Furthermore, PLX3397 reduced the clonogenic capacity of DKO mice in their peripheral blood and spleen and prolonged their survival. Flow cytometric analysis demonstrated that PLX3397 treatment increased the number of early erythroid progenitor cells and LSK cells in the bone marrow of DKO mice, partially ameliorating their hematopoietic defects. Overall, this study reveals the potential efficacy of PLX3397 in treating MDS mouse models and provides a new approach for the clinical treatment and alleviation of myelofibrosis caused by MDS.
