A new flavonoid 1 rhamnocitrin-3-O-（6＂-femloyl）-β-D-galactopyranoside-4＇-O-β-D- glucospyranoside called kansuensisoside A together with a known flavonoid 2 （rhamnocitrin- 3-O-β-D-galactopyranoside-4＇-O-β-D-glucospyranoside） were isolated from the extract of the whole plant of Oxytropis kansuensis Bunge. The structure of 1 was elucidated by spectroscopic methods including 2D-NMR techniques （COSY, HMQC, HMBC） and HR-ESIMS.

Fast radio bursts(FRBs) are highly dispersed millisecond-duration radio bursts,[1,2]of which the physical origin is still not fully understood. FRB 20201124A is one of the most actively repeating FRBs. In this paper, we present the collection of 1863 burst dynamic spectra of FRB 20201124A measured with the Five-hundred-meter Aperture Spherical radio Telescope(FAST). The current collection, taken from the observation during the FRB active phase from April to june 2021, is the largest burst sample detected for any FRB so far. The standard PSRFITs format is adopted, including dynamic spectra of the burst, and the time information of the dynamic spectra, in addition, mask files help readers to identify the pulse positions are also provided. The dataset is available in Science Data Bank, with the link https://***/10.57760/sciencedb.j00113.00076.

为科学指导新型冠状病毒肺炎(以下简称新冠肺炎,COVID-19)疫情期间集中隔离医学观察场所内感染防控工作,在早期有效识别感染者的同时,有效避免集中隔离医学观察场所内的交叉感染,中华预防医学会医院感染控制分会、中国医院协会医院感染管理专业委员会、中国感染控制杂志编辑部组织有关专家共同制定本共识。本共识适用于确诊病例、疑似病例、无症状感染者的密切接触者、密切接触者的密切接触者,以及入境人员或其他根据防控工作需要“应隔尽隔”人员开展集中隔离医学观察时所设置的集中隔离医学观察场所,指导其工作人员正确做好个人防护及防止感染传播工作,避免发生场所内感染及传播。本共识借鉴医疗机构内新型冠状病毒感染防控的基本原则、文件规范,结合集中隔离医学观察场所的特点与实际工作情况,对不同区域工作人员、工作环节开展新型冠状病毒传播的风险评估,并据此对集中隔离医学观察场所的感染防控组织架构、选址布局、人员防护、人员闭环管理、清洁消毒、环境核酸监测、人员健康监测、职业暴露处理及交叉感染判定原则等感控相关工作给予指导。
