Medical Genetics is a subject to study the medicine by using genetics knowledge. The subject studies the mechanism of genetic diseases, methods of inheritance, roles of developing that and provides the scientific evidence for controlling genetic diseases in the case of improving human genetic qualities.
During the medical education, Medical Genetics has a tight connection with basic subjects, including Medical Cell Biology, Biochemistry, Physiology, Immunology, Pathology, Embryology, Clinicol Medicine Pharmacy and Social Medicine.
This text book is a teaching material of medical teaching planning for foreign students in Chinese. Medical Universities and a references book for postgraduate students, and it is also provided for foreign students from relative majors and for clinic doctors in other mdical universities nationwide.
We will introduce the book from the following acpects:
This book includes 11chapters and 4 parts, The chapters includes introduction, Mendel’s law of inheritance, the bases of genetics, monogenic diseases, mitochondrial disorders, multifactorial inheritance, human chromosomes, chromosome disorders, biochemi genetics, diagnosis of genetic diseases, treatment of a genetic diseases; The A Parts are overall review of medical genetics, model test, standard answer and experimental guide of medical genetics.
i For studying well teaching material, each chapter of the book provides teaching purposes, teaching requirements and teaching contents for the students according to the syllabus of Medical Genetics of Xinjiang Medical University. Teaching requirements are divided into three levels they are mastery, familiarity and understanding. Teaching contents are coordinated with the teaching requirements.
ii At the end of each chapter, we offerd a summary for students to review of the chapter knowledge.
iii Each chapter also provided different forms of exercises, which include key terms, fill in the blank, true or false and MCQs The total sum of exerises are more than 500. Suggested answers are attached.
iv Overall review is provided at the end of 11 chapters.
v In order to let students understand the pattern of written exams of Medical Genetics in Xinjiang Medical University, one model test is given at the end of the book.
vi Experimental guides are also given, as well as experimental reports included in this part.
We hope that this text book will meet your needs for the basic of the Medical Genetics curriculum, and we welcome and appreciate your comments, which will help us refine the reprint for future students. thank you!
