The pandemic of the coronavirus disease 2019(COVID-19) has become a global public health crisis. The symptoms of COVID-19 range from mild to severe, but the physiological changes associated with COVID-19 are barely understood. In this study, we performed targeted metabolomic and lipidomic analyses of plasma from a cohort of patients with COVID-19 who had experienced different symptoms. We found that metabolite and lipid alterations exhibit apparent correlation with the course of disease in these patients, indicating that the development of COVID-19 affected their whole-body metabolism. In particular, malic acid of the TCA cycle and carbamoyl phosphate of the urea cycle result in altered energy metabolism and hepatic dysfunction, respectively. It should be noted that carbamoyl phosphate is profoundly down-regulated in patients who died compared with patients with mild symptoms. And, more importantly, guanosine monophosphate(GMP), which is mediated not only by GMP synthase but also by CD39 and CD73, is significantly changed between healthy subjects and patients with COVID-19, as well as between the mild and fatal cases. In addition, dyslipidemia was observed in patients with ***, the disturbed metabolic patterns have been found to align with the progress and severity of COVID-19. This work provides valuable knowledge about plasma biomarkers associated with COVID-19 and potential therapeutic targets, as well as an important resource for further studies of the pathogenesis of COVID-19.

研究黄铜矿、黄铁矿、方铅矿等矿物在有/无捕收剂两种情况下的浮选行为,考察浮选与矿浆电位的关系。结果表明：当pH值分别小于4.0时,黄铜矿无捕收剂浮选的电位区间为0~0.9 V;当pH值为4.0或11.0时,矿浆电位大于0.85 V以后,黄铁矿的浮选回收率低于20%;当pH值为11.0时,黄铜矿无捕收剂浮选的矿浆电位区间为0.35~0.85 V。当pH值为10.0、丁黄药浓度为5×10-5 mol/L时,方铅矿浮选的矿浆电位为0.45~0.55 V,而黄铜矿在0.45~0.80 V的电位区间具有良好的浮选性能;对闪锌矿而言,当pH值为9.0时,矿浆电位在-0.40~0.80 V区间都不具有良好的可浮性。在浮选体系中,黄铜矿表面氧化会产生元素S0,当矿浆电位从-0.2V增大至0.6 V,黄铜矿表面氧化产生的元素S的数量逐渐增大,黄铜矿的无捕收剂浮选性能越来越好。从南京和青海2个铅锌矿山的应用情况来看,采用电位调控浮选技术可以大幅度缩短铅矿石的浮选时间,减少浮选机数量。例如在南京某铅锌矿,由于采用电位调控浮选技术,原来2个系列每天处理900 t矿石,现在采用一个系列即可处理。
