To solve this problem, a scheme based on double layer Ether CAT and optical fiber interlock net was proposed. The system is mainly composed of double layer Ether CAT, optical fiber interlock net, ground monitoring station, underground control stations and integrated protection devices with Ether CAT communication interface and interlock interface. Double layer Ether CAT and optical fiber interlock net cooperate with each other, when one is interrupted, the other net carl realize selectivity of short circuit protection independently, Results of test show that the system can achieve selectivity of short circuit protection reliably, determine the fault location quickly, shorten troubleshooting time and improve safety and reliability of the power network in coal mines.展开更多

Methods:A total of 98 cases of patients with newly diagnosed T2DM complicated by obesity in this hospital between March 2016 and February 2017 were randomly divided into the control group (n=49) and the exenatide group (n=49). Control group received oral hypoglycemic drugs combined with insulin therapy, and exenatide group received exenatide combined with oral hypoglycemic drug therapy. The differences in BMI levels, blood glucose levels and inflammatory factor contents were compared between the two groups of patients before and after treatment. Results: Before treatment, there was no statistically significant difference in BMI levels, blood glucose index levels in peripheral blood and inflammatory factor contents in serum between the two groups. After 3 months of treatment, the BMI level in exenatide group was lower than that in control group;blood glucose indexes FBG and 2h BG levels in peripheral blood of exenatide group were lower than those of control group;inflammatory factors IL-6, VCAM-1, MCP-1 and TNF-α contents in serum of exenatide group were lower than those of control group. Conclusions: Exenatide combined with oral hypoglycemic drug therapy can more effectively reduce the body weight, optimize the blood glucose level and relieve the systemic micro-inflammatory state in patients with newly diagnosed T2DM combined with obesity.展开更多
