[Progress on the research of lactose intolerance].

Our group generalized the research development of lactose intolerance, both internationally and nationally. We systematically reviewed the pathogenesis, genetic polymorphisms of lactase deficiency, relevant progress of diagnostic methods and treatment. Through this systematic review, we undedrstood that there were insufficient research efforts made on understanding the epidemiological feature of lactose intolerance in this country. Relevant genetic mutations of people were also not clear, neither the development of simple and effective diagnosis method made. We should continue to extensively and deeply carry out the study regarding methods for early prevention and intervention on lactose intolerance.
