Objective To study the latest research progress of the formation mechanism of cholesterol stone disease and forming factors of cholesterol stone disease and to provide new theoretical level and develop a new development direction for guiding clinical application. Methods The related literatures at home and abroad were analyzed, compared and summarized, and the current relevant research dynamic of cholesterol stone disease was sketched. Results The formation of cholesterol gallstone is closely related to the abnormal levels of serum lipids metabolism, bacterial and viral infection, and the expression of genes related to cholesterol gallstone. Conclusions The formation of cholesterol calculus disease is a kind of interaction and intricate disease process involving of environmental factors, genetic factors, and biological factors. Although there has been a lot of blood lipid, protein correlation research with cholesterol stone, there are also many studies such as using gene transplantation and gene knockout, but gene technology of cholesterol stone disease diagnosis and treatment is expected to become the new hot research topic.
ObjectiveTo investigate the relationship between insulin-like growth factor binding protein (IGFBP) gene with pancreatic cancer. MethodsThe relevant literatures at home and abroad in recent years were reviewed. From the pancreatic cancer related genes, IGFBP related tumors and the correlation between IGFBP and pancreatic cancer research and other aspects of the previous research results were summaried. ResultsMost of the studies suggested that IGFBP could inhibit the function of tumor cells through the IGF dependent pathway, but the deletion or mutation of IGFBP gene and its regulation mechanism are still unclear. ConclusionIGFBP is closely related to the tumor, but its specific effects and mechanism of pancreatic cancer has not been settled. In order to affect the degree of cell differentiation, regulation of tumor growth and metastasis probability through the change of endogenous IGFBP gene level, the further studie is needed.
