Background and aims:Although some studies have identified a possible link between the De Ritis ratio and the mortality of patients with COVID-19),the predictive value and the optimal cut-value remain *** study aimed to explore the correlation between the De Ritis ratio and mortality in hospitalized ***:The data for this cohort study came from a retrospective cohort study that was carried out in a medical system in New York *** primary outcome was the in-hospital mortality of included *** researchers ran multivariate Cox regression analyses,curve fitting,and subgroup analysis to support our *** survival in different De Ritis ratio groups was plotted as Kaplan-Meier survival ***:The study enrolled 4371 participants with COVID-19 from March 1,2020 to April 16,*** overall mortality was 24.8%(1082/4371).The curve fitting analyses indicated that the De Ritis ratio has a positive linear connection with mortality in patients with *** adjusting for all covariates,participants with a De Ritis ratio≥2 exhibited 1.29 times the risk of in-hospital mortality compared with those with a De Ritis ratio<1(hazard ratio 1.29,95%confidence interval 1.02-1.62,p=0.031).The p for trend was<0.05 for all *** in the group with a De Ritis ratio≥2 experienced the shortest survival time in the Kaplan-Meier survival ***:A higher baseline De Ritis ratio is correlated with a corresponding higher mortality among hospitalized people with COVID-19.

直流断路器是轨道交通直流牵引供电系统的关键设备。目前直流牵引供电系统中以空气式直流断路器为主,其关断过程存在金属触头以及灭弧栅片烧蚀,开断速度慢的问题。针对以上问题,提出一种非对称桥式混合式直流断路器,具有关断速度快、双向开断、经济性好的特点。首先分析了该拓扑的工作原理,然后分析了断路器关键部件的参数对分断过程的影响,基于该技术路线研制了直流断路器低压物理样机及动态模拟试验平台,开展了断路器分断试验,结果表明非对称桥式直流断路器能够在3 m s内实现系统故障电流的快速关断,并且在经济性、紧凑性、重合闸等方面具有优势。

作者： Zhai Gaixia Wang Zhenhua He Gang Liu guilin yang Li Hohhot Branch of Chinese Academy of Agricultural Mechanization Sciences Hohhot 010020 China

Based on the mechanical and physical properties study of forage grass seeds, multi-line with one-device type metering device was designed. It was composed of adjustable screw, stirrer, metering device housing and central metering sheave and so on. The sowing rate can be set by turning the screw to change the working length of the central metering sheave relative to the metering device housing. The stirrer inside of the sheave housing is used to prevent seeds overhead. And metering of different sizes of seed is adjusted by changing the position of internal components of the slot wheel mechanism. Innovative design on the structure of the central metering sheave was finished. According to the structure parameters and physical characteristic parameters, different seed sowing rate of per hectares was calculated. And then the working length scale of the central metering groove wheel was made. And there is a one-to-one correspondence between scale values and sowing quantity per hectare of different kinds of seed.

[Objectives]To establish a UPLC-UV method for the determination of polydatin in the serum of Wistar rats.[Methods]Acquity UPLC BEH shield RP18 column(1.7μm,2.1 mm×100 mm,Waters Corporation,USA)was used as the analytical column,acetonitrile-water(55∶45)was used as the mobile phase,the flow rate was 0.5 mL/min,and the column temperature was 30℃and the detection wavelength was 306 nm.[Results]The linear range of the established serum sample analysis method was 1.0-20.0μg/mL,and the correlation coefficient was r=0.9994;the intraday and interday RSD of Wistar rat serum was less than 3.0%,and the accuracy was higher than 90%.[Conclusions]This method is sensitive,accurate,and *** is suitable for monitoring the concentration of polydatin in serum after intragastric administration,and can also be used for pharmacokinetics and bioavailability studies.
