Based on the announcement of the World Health Organization(WHO) in 2018, the Wuhan pneumonia caused by an unknown etiology should be recognized as the first Disease X. Later, the pathogen was identified to be a novel coronavirus denoted 2019-nCoV, which has 79.5% and 96% whole genome sequence identify to SARS-CoV and bat SARS-related coronavirus(SARSr-CoV-RaTG13), respectively, suggesting its potential bat origin. With high human-to-human transmission rate(R0), 2019-nCoV has quickly spread in China and other countries, resulting in 34,953 confirmed cases and 725 deaths as of 8 February 2020, thus calling for urgent development of therapeutics and prophylactics. Here we suggest renaming 2019-nCoV as "transmissible acute respiratory syndrome coronavirus(TARS-CoV)" and briefly review the advancement of research and development of neutralizing antibodies and vaccines targeting the receptor-binding domain(RBD) and viral fusion inhibitors targeting the heptad repeat 1(HR1) domain in spike protein of 2019-nCoV.

BACKGROUND Acid-base imbalance has been poorly described in patients with coronavirus disease 2019(COVID-19).Study by the quantitative acid-base approach may be able to account for minor changes in ion distribution that may have been over-looked using traditional acid-base analysis *** a cohort of critically ill COVID-19 patients,we looked for an association between metabolic acidosis surrogates and worse clinical outcomes,such as mortality,renal dialysis,and length of hospital *** To describe the acid-base disorders of critically ill COVID-19 patients using Stewart’s approach,associating its variables with poor *** This study pertained to a retrospective cohort comprised of adult patients who experienced an intensive care unit stay exceeding 4 days and who were diagnosed with severe acute respiratory syndrome coronavirus 2 infection through a positive polymerase chain reaction analysis of a nasal swab and typical pulmonary involvement observed in chest computed tomography *** and clinical data were obtained from electronic *** variables were compared using Fisher’s exact *** data were presented as median and interquartile *** Mann-Whitney U test was used for *** In total,211 patients were *** mortality rate was 13.7%.Overall,149 patients(70.6%)presented with alkalosis,28 patients(13.3%)had acidosis,and the remaining 34 patients(16.2%)had a normal arterial pondus *** those presenting with acidosis,most had a low apparent strong ion difference(SID)(20 patients,9.5%).Within the group with alkalosis,128 patients(61.0%)had respiratory *** non-survivors were older,had more comorbidities,and had higher Charlson’s and simplified acute physiology score *** did not find severe acid-base imbalance in this *** analyzed Stewart’s variables(effective SID,apparent SID,and strong ion gap and the effect of albumin,lactate,phosphorus,and chloride)were not d
