The management of laryngeal cancer and hypopharyngeal cancer has fundamentally changed over the recent years. The optimum treatment protocols should pay close attention to the survival rate and function preservation. The purpose of this article we aimed to define the prevalence of intervention of laryngeal cancer and hypopharyngeal cancer, such as open operation, CO2 laser and non-invasive treatments, and measures that may facilitate standardization of such practices.

Gastric cancer is the common malignant tumor of digestive tract,and liver metastasis in patients with advanced gastric carcinoma is the most common cause of death.The early diagnoisis of Liver metastasis of gastric cancer in patients with early diagnosis would help to improve the patient' s quality of life and prognosis.Briefly review the blood,imaging and pathological biopsy method in early diagnosis of liver metastasis of gastric cancer.However it is difficult for this.Researchers over the world should have more exchanges in order to develop guiding principles in the end.

Sudden infant death syndrome(SIDS) has become a highlighted topic in forensic medicine and pediatrics since it was firstly defined in 1969.As some great improvements were preceded in many aspects,people know more about its features,summarization,classification and related genes.There are many reports from developed areas such as North America,Europe,Australia,Japan etc.,but few from China.This review introduces SIDS's development history,new scientific findings and discusses the feasibility of further SIDS studies and the key points in forensic practice under the influence of San Diego definition of SIDS.

Acromegaly is mostly caused by a pituitary adenoma secreting growth hormone ( GH ) , which leads to a wide range of endocrine morbidities, with an insidious onset and slow progression.A long-term overproduction of GH results in elevated insulin-like growth factor-1 ( IGF-1 ) level, which in turn, would cause target organ damage and an increased risk for mortality and decreased quality of life.Herein, the literature regarding the progress of drug therapy for acromegaly in recent five years is reviewed.

Objective:To study the correlations between ethics morality, society, psychological cognition and health and disease. Methods:A total of 356 patients were selected to analyze the influence to health and disease from six perspectives that included family ethics, social morality, life style, interpersonal relationship, mental health, and personality traits. Result:Psychosomatic diseases were occurred in 126 cases, and 220 cases of neuro-sis diseases. The disease incidences in the subjects with high cognitive level were significantly lower than those with low cognitive level (P<0. 01). The cognitive levels of family ethics, social ethics, life style, interpersonal rela-tionship, and mental health were closely related to health and disease (P<0. 05). Conclusion:The cognitive lev-els of ethics morality, society, psychology were closely associated with disease. It should be vigorously advocated that the whole society follow the ethics morality standards, to prevent diseases.

OBJECTIVE: To discuss the biosafety and biocompatibility of biomaterials. METHODS: A computer-based online search of CNKI, CBM and VIP as well as manual search were performed to collect articles about random cell control experiments and animal experiments of biological material biocompatibility published between 1990 and 2008. A total of 28 Chinese literatures were collected, and 7 were included mainly involving the cytotoxicity test methods and blood compatibility of the experimental medium, experimental grouping, experimental materials, methods of observation, experimental results, and experimental conclusion. In addition, biocompatibility of the biological material was analyzed to summarize the biocompatibility of the biological safety. RESULTS: Based on experiments of biosafety and biocompatibility of biomaterials, the cytotoxicity test and blood compatibility of various biomaterials, such as collagen, chitosan, magnetic nanoparticle, metal vascular stent, sulphurated siliastic medical grade silicon rubber, polyurethane, ceramic coatings by micro-arc oxidation, are essential for the biological safety. The experimental results have shown that the biomaterials have good biocompatibility. CONCLUSION: A variety of biological materials present good biocompatibility, including collagen, chitosan, magnetic nanoparticle, metal vascular stent, sulphurated siliastic medical grade silicon rubber, polyurethane, ceramic coatings by micro-arc oxidation, based on the evaluation criteria.
