Due to the intrinsic advantages of nontoxicity, low-cost, and abundant resource of metallic zinc, aqueous zinc-ion batteries (ZIBs) have attracted universal interest [1,2]. Tremendous cathode materials have been exploited in aqueous ZIBs, such as manganese-based materials [3-11], Co-based materials [12,13] and vanadium-based materials [14-21].

Objective This study aimed to determine the association of hyperlipidemia with clinical endpoints among hospitalized patients with COVID-19,especially those with pre-existing cardiovascular diseases(CVDs)and diabetes.Methods This multicenter retrospective cohort study included all patients who were hospitalized due to COVID-19 from 21 hospitals in Hubei province,China between December 31,2019 and April 21,2020.Patients who were aged<18 or≥85 years old,in pregnancy,with acute lethal organ injury(e.g.,acute myocardial infarction,severe acute pancreatitis,acute stroke),hypothyroidism,malignant diseases,severe malnutrition,and those with normal lipid profile under lipid-lowering medicines(e.g,statin,niacin,fenofibrate,gemfibrozil,and ezetimibe)were excluded.Propensity score matching(PSM)analysis at 1:1 ratio was performed to minimize baseline differences between patient groups of hyperlipidemia and non-hyperlipidemia.PSM analyses with the same strategies were further conducted for the parameters of hyperlipidemia in patients with increased triglyceride(TG),increased low・density lipoprotein cholesterol(LDL-C),and decreased high-density lipoprotein cholesterol(HDL-C).Mixed-effect Cox model analysis was performed to investigate the associations of the 28-days all-cause deaths of COVID-19 patients with hyperlipidemia and the abnormalities of lipid parameters.The results were verified in male,female patients,and in patients with pre-existing CVDs and type 2 diabetes.Results Of 1094S inpatients confirmed as COVID-19,there were 9822 inpatients included in the study,comprising 3513(35.8%)cases without hyperlipidemia and 6309(64.2%)cases with hyperlipidemia.Based on a mixed-effect Cox model after PSM at 1:1 ratio,hyperlipidemia was not associated with increased or decreased 28-day all-cause death[adjusted hazard ratio(HR),1.17(95%C/,0.95-1.44),P二0.151].Wb found that the parameters of hyperlipidemia were not associated with the risk of 28-day all-cause mortality[adjusted HR,1.23(95%CI,0.98-1.55),P=0.075 in TG increase group;0.

滇东南富宁地区地处扬子陆块西南缘,区内分布有多个以“半瓦型”辉绿岩为容矿岩石的卡林型金矿床(点),即金矿体产于不同规模辉绿岩体的内接触带,以及岩体内部的同生张性裂隙中。通过对新鲜辉绿岩(成矿前)的主量、微量及稀土元素特征进行研究,发现其属于亚碱性玄武岩系列,具有板内玄武岩的地球化学特征;对其构造环境进行判别并结合区域构造演化特征,表明辉绿岩为印支期碰撞造山运动后基性岩浆沿区域断裂上升侵入的产物。在野外调查的基础上,与前人对含矿辉绿岩地球化学特征的研究进行对比分析,结合辉绿岩的成岩时代、以辉绿岩为容矿岩石的金矿床成矿时代,综合分析认为:辉绿岩浆为此类金矿床的形成提供了部分成矿物质,为成矿流体提供了热源,同时活化、萃取地层中的金元素,从而在有利的构造部位富集成矿。
