Objective To evaluate the long-term prognosis of patients with ST-segment elevation myocardial infarction(STEMI)treated with different reperfusion strategies in Chinese county-level hospitals Methods A total of 2,514 patients with STEMI from 32 hospitals participated in the China Acute Myocardial Infarction registry between January 2013 and September *** success of fibrinolysis was assessed according to indirect measures of vascular *** primary outcome was 2-year *** Reperfusion therapy was used in 1,080 patients(42.9%):fibrinolysis(n=664,61.5%)and primary percutaneous coronary intervention(PCI)(n=416,38.5%).The most common reason for missing reperfusion therapy was a prehospital delay>12 h(43%).Fibrinolysis[14.5%,hazard ratio(HR):0.59,95%confidence interval(CI)0.44–0.80]and primary PCI(6.8%,HR=0.32,95%CI:0.22–0.48)were associated with lower 2-year mortality than those with no reperfusion(28.5%).Among fibrinolysistreated patients,510(76.8%)achieved successful clinical reperfusion;only 17.0%of those with failed fibrinolysis underwent rescue *** was no difference in 2-year mortality between successful fibrinolysis and primary PCI(8.8%vs.6.8%,HR=1.53,95%CI:0.85–2.73).Failed fibrinolysis predicted a similar mortality(33.1%)to no reperfusion(33.1%vs.28.5%,HR=1.30,95%CI:0.93–1.81).Conclusion In Chinese county-level hospitals,only approximately 2/5 of patients with STEMI underwent reperfusion therapy,largely due to prehospital *** 30%of patients with failed fibrinolysis and no reperfusion therapy did not survive at 2 *** improvement initiatives are warranted,especially in public health education and fast referral for mechanical revascularization in cases of failed fibrinolysis.

Li-O_(2)batteries with high energy density hold significant promise as next-generation energy storage ***,Li-O_(2)batteries have poor cycling performance at high current densities and large capacities,primarily due to the high impedance caused by the instability of the lithium anode and the sluggish kinetics in the discharge products decomposition on the ***,we investigated a bifunctional nitrile additive(2-methoxy benzonitrile(2-MBN))with good chemical/electrochemical stability to improve the performances of Li-O_(2)*** 2-MBN could actively modify the anode by ensuring uniform Li+deposition and optimizing the composition of solid electrolyte interphase(SEI).Meanwhile,it could also facilitate the decomposition of discharge products by inducing the formation of sheet-like Li_(2)O_(2),significantly reducing the battery charge *** bifunctional effects of 2-MBN for the anode and cathode enable Li-O_(2)batteries to achieve a stable lifetime of 97 cycles at a current density of 600 mA·g^(−1)with a fixed capacity of 2000 mAh·g^(−1),much better than that of Li-O_(2)batteries without 2-MBN(28 cycles).The inclusion of 2-MBN provides an effective approach for attaining high-performance Li-O_(2)batteries.
