Objective The use of targeting therapy for the treatment of gastric glandular cancer has been a hot topic in recent years. This study aims to clarify that through what ways the histone deacetylase inhibitor MS-275 completes its selectively killing effect on gastric glandular cancer cell line SGC-7901. Methods SGC-7901 cells and GES-1 cells were respectively cultured for 24h, with(10-100) μmol/L concentrations of MS-275. (1) The survival rate of SGC-7901 cells, GES-1 cells and the normal cells were analyzed by WST-1; (2) The change of the mitochondrial membrane potential in SGC-7901 was estimated by flow cytometry;(3) The expression levels of p21, p27, p57, cyclinB1, cyclinD1 were determined by Western blot and PCR methods. Results (1) MS-275 could decrease the survival rate of SGC-7901 cells, the effect was significantly enhanced with the increasing of the concentration (P<0.05), but MS-275 showed no obvious effect on normal gastric mucosa epithelial cells GES-1; (2) MS-275 treatment could decreased the mitochondrial membrane potential of SGC-7901 cells (P<0.05); (3) MS-275 treatment could increase the relative contents of p21, p27, p57 genes and their protein and, at the same time, decrease the relative contents of CyclinB1 and CyclinD1 (P<0.05). Conclusion MS-275 treatment can selectively kill gastric glandular cancer cells SGC-7901 through several possible ways, such as inducing mitochondrial apoptosis and regulating the expression levels of cell cycle-related genes and proteins.

This paper systematically summarized the core problems in the field of medical and health services and did the root analysis.It is concluded that the current domestic and international related medical service modes deviated from the essence of health services and led to difficulties in the idea and method,bringing people to new problems and new crises.KY3H health care service model,set innovative ideas,innovative technical methods,innovative products,innovative processes,standards and standards into one,by providing a full range and the whole cycle of people-oriented,self-help,"diagnosis and treatment of security" integration of health careservice,improve people's health status,fundamentally change the traditional passive "seeking medical treatment" service mode,to active "seeking one's own" health service mode,so as to achieve "health status continues to rise,the medical costs continue to decline,"which is the social development aims.The paper systematically analyzes the idea,operational logic,goal,mode structure,characteristics of the model,and its significance to individuals,industries,society,countries and even the international community in order to make a positive contribution to the healthy development strategy in China and provide a Chinese case for global Health.

Vigorously development of the health service industry has received great attention,but the health service industry faces many difficulties.By analyzing the current predicament,this paper put forward the KY3H health care service model and systematically analyzed its six innovations:from "disease as the center" to "health as the center",from "homogenized group health service" to "Personalized and Humanized Health Service",from "Extensive Health Service"to "Precise Intervention of Individual Health Status",from "Single Health Service" to "Trinity Service of Health,Culture,Health Management and Health Insurance",from the "seeking medical" service model to "seeking one's own"service model,as well as from the "fixed (fixed-time,fixed-point,fixed-mode) service" to "anytime,anywhere full-time service".This model has achieved initial success in practice.It is an important way to solve the dilemma.
