Objective To analyze and compare the capacity and efficiency of county-level hospitals′medical service by using the diagnosis related groups ( DRGs ) method. Methods The homepage data of discharged inpatients from seven county-level hospitals in Wenzhou region in 2013 - 2015 period were analyzed, for measurement of the medical service capacity changes of such hospitals using the number of DRGs, total multiplicity of weight, and CMI value, and that of their medical service efficiency changes using expense consumption index and time consumption index. Results The study found in the seven hospitals 8. 49% increase of the total number of DRGs, 17. 34% increase of total multiplicity of weight, and 5. 06%increase of CMI value, with unchanged expense consumption index and 9. 82% decrease of the time consumption index. These facts evidenced enhancements of these hospitals in both service capacity and service efficiency in general. Conclusions DRGs as tools prove useful objectively and scientifically. Policies of Two emphases at primary ends and two enhancements have been implemented desirably.

β2 microglobulin (β2-MG) is a key component I molecule of the major histocompatibility complex class that assists in the cytotoxic T lymphocyte (CTL) immune response. Serum β2-MG content is dynamically correlated with many diseases. Most studies on β2-MG mainly focus on the pathogenesis of kidney disease, tumor and amyloid fibrils. In recent years, some studies have found that β2-MG is also involved in the adverse prognosis of cardiovascular system, cognitive impairment of aging and antibacterial effects. This paper summarized the domestic and foreign studies on β2-MG in recent years, and proposed the possible role of β2-MG in multi-system human body and its potential application prospect of drug molecular targeting.
