Elemene, derived from Curcuma wenyujin, one of the "8 famous genuine medicinal materials of Zhejiang province," exhibits remarkable antitumor activity. It has gained wide recognition in clinical practice for effectiveness on tumors. Dr. XIE tian introduced the innovative concept of "molecular compatibility theory" by combining Chinese medicine principles, specifically the "monarch, minister, assistant, and envoy" theory, with modern biomedical technology. This groundbreaking approach, along with a systematic analysis of Chinese medicine and modern biomedical knowledge, led to the development of elemene nanoliposome formulations. These novel formulations offer numerous advantages, including low toxicity, well-defined composition, synergistic effects on multiple targets, and excellent biocompatibility. Following the principles of the "molecular compatibility theory", further exploration of cancer treatment strategies and methods based on elemene was undertaken. This comprehensive review consolidates the current understanding of elemene's potential antitumor mechanisms, recent clinical investigations, advancements in drug delivery systems, and structural modifications. The ultimate goal of this review is to establish a solid theoretical foundation for researchers, empowering them to develop more effective antitumor drugs based on the principles of "molecular compatibility theory".

本文利用法国国家科研中心(CNRS)动力气象实验室(LMD)发展的可变网格的格点大气环流模式LMDZ4,对1998年东亚夏季降水进行了模拟,考查了变网格模式对东亚夏季降水的模拟性能.结果表明,模式在一定程度上能模拟出东亚夏季降水的极大值中心、夏季风雨带以及降水由东南向西北递减的空间分布特征.模式基本再现了1998年夏季两次雨带的进退特征,包括降水强度、雨带范围等,从而合理再现了1998年夏季江淮地区的"二度梅"现象.与观测相比,模拟的不足在于:在陡峭地形区附近存在虚假降水;江淮和华北地区以及四川盆地存在水汽输送的气旋式辐合偏差,同时高层环流辐散偏强,使得下层暖湿空气辐合上升、降水偏多;在东南地区存在反气旋式的水汽输送偏差,30°N以南地区降水偏少.对于1998年的"二度梅"现象,模拟偏差主要表现为长江中下游地区两次(特别是第二次)较强降水持续时间偏短,强降水范围偏小,而黄淮和华南地区却降水偏多.分析表明,模式对两次梅雨期降水的模拟偏差直接受环流形势模拟偏差的影响.LMDZ4区域模式版本的特点一是区域加密,二是加密区内预报场每10天向再分析资料恢复一次.敏感试验结果表明,LMDZ4加密区向强迫场的10天尺度恢复总体上有利于提高模式对华北降水的模拟能力,而对长江流域和华南降水的模拟具有不利影响.较之均匀网格模拟试验,加密试验由于在东亚的分辨率大大提高,对东亚夏季降水模拟效果更好.
