Objective To establish a method of quick three-dimensional (3D) reconstruction of pubic symphysis based on magnetic resonance imaging. Methods The pelvis images of adult male were generated on a 3.0 T scanner using a T1 Gradient Echo FLASH-3D (T1- FL3D) sequence and imported the images into medical image control system. Segmentation of binaryzation threshold was conducted and pelvic soft tissue image was extracted by regional growth, 3D structure model of pubic symphysis was obtained by Boolean operation. The 3D structure model of pubic symphysis was established by the noise reduction of reverse engineering software. And compared with the 3D reconstruction model pubic bone CT scan. Results The morphological characters of the MRI pubic symphysis 3D model, such as the ridges and furrows on the symphysial surface, lower extremity, dorsal margin (beveling), margin (beveling) and pubic tubercle, were highly consistent with the morphological characters of the 3D model established by CT scan. Conclusion MRI scan can be used to reconstruct the 3D structure of pubic symphysis quickly and effectively, and it can provide a safe radiation-free 3D visualization imaging technique for forensic age estimation for the living.

Ferroptosis is a unique iron-dependent cell death pattern,a novel death phenotype distinct from apoptosis,va-rious forms of necrosis,and autophagy.Numerous active ingredients extracted from traditional Chinese medicine have been found to exert anti-cancer effects by inducing ferroptosis in various cancers.An increasing number of studies have found that the regulation of ferroptosis can influence the sensitivity of tumor cells to drugs and even reverse drug resistance.When combined with chemo-therapy drugs such as cisplatin,5-FU and gemcitabine,some natural products enhance cancer cells'sensitivity to chemothera-peutic drugs by inducing ferroptosis.This paper mainly summarizes traditional Chinese medicine and its natural products that can exert anti-cancer effects by inducing ferroptosis,providing new insights for cancer treatment and drug resistance reversal.Addition-ally,it contributes to exploring the potential advantages of traditional Chinese medicine,thereby expanding its scope of applica-tion.
