　　I first express my sincere gratitude to Dr. Jason Payne-James， Dr. Steven Karch， Dr. Richard Jones and Dr. John Manlove for their outstanding contributions to this book， which reflect the accumulation of their wisdom and knowledge. This textbook has been well accepted by students for its thorough explanation of key principles of forensic medicine and forensic science with judiaal practice， as well as its clear visuallayout， which aids in the learning pro- cess. We appreciate an endowment from the People's Medical Publishing House， which is responsible for the reorganization of this textbook， and the under- standing and support of the CRC Press in publishing a rearranged version of this book in China.
　　This textbook includes the main disciplines of forensic science， such as forensic pathology and forensic toxicology. However， in China， forensic application also cover the forensic clinical medicine， forensic psychiatry， forensic biology and so on. Therefore， it is necessary to expand the scope of this textbook in order to meet the needs of China's current judicial practice. Meanwhile， the rapid development of forensic medicine calls for new textbooks to update knowledge of the field for international students and undergraduates in China. For these purposes， we reorganized Simpson's Forensic Medicine， 13th edition， according to the education protocolin China.
　　The contents of the new edition will be arranged in the following order： ethics， identification and assessment of the deaths， disability， diseases， injuries， sexual assault， child assault， mental state， alcohol consuming， poisoning， as well as DNA analysis in biological samples. It also focuses on historical background， the interpreting of scientific evidence for the investigation and trial of criminal cases， civil cases， medical malpractice， as well as those dealing with forensic saence and the law， which is expected to help solve medicine-related problems in forensic practice.
　　I would like to acknowledge all of my colleagues for their generous contributions of time and work.
　　Their endeavors and professionalism guarantee the success of the rearranged edition.
　　I antiapate that this rearranged version will help readers in China better understand the principles and application of forensic mediane.
