RESUMEN
In the outbreak of COVID-19,triage procedures based on epidemiology were implemented in a local hospital in Changsha to control the transmission of SARS-CoV-2 and avoid healthcare-associated infection.This re-trospective study analyzed the data collected during the triage period and found that COVID-19 patients were en-riched 7 folds into the Section A designated for patients with obvious epidemiological history.On the other side,nearly triple amounts of visits were received at the Section B for patients without obvious epidemiological history.8 COVID-19 cases were spotted out of 247 suspected patients.More than 50％of the suspected patients were submi-tted to multiple rounds of nucleic acid analysis for SARS-CoV-2 infection.Of the 239 patients who were diagnosed as negative of the virus infection,188 were successfully revisited and none was reported as COVID-19 case.Of the 8 COVID-19 patients,3 were confirmed only after multiple rounds of nucleic acid analysis.Besides comorbidities,delayed sharing of epidemiological history added complexity to the diagnosis in practice.The triaging experience and strategy will be helpful for the control of infectious diseases in the future.
RESUMEN
Cardiac arrest seriously endangers patients' life, and has the characteristics of low success rate of resuscitation,high mortality rate, and poor neurological prognosis. At present, cardiopulmonary resuscitation education is mainly adopted to improve the success rate of rescue in our clinical practice, and some clinical practices and studies are also conducted to explore the prognostic factors of ROSC after cardiac arrest. In this paper, the factors of pre-arrest, peri-arrest and post-ROSC,which may be related to the prognosis of ROSC after cardiac arrest, were discussed.
RESUMEN
<p><b>OBJECTIVE</b>To study the association of ITGA9 gene rs189897 and rs2212020 polymorphisms and its haplotype with the occurrence of cerebral infarction (CI).</p><p><b>METHODS</b>In the venous blood samples from 250 patients with cerebral infarction and 250 control samples, the genotypes of rs189897 and rs2212020 of ITGA9 gene were identified by PCR-sequencing. SHEsis software was used to analyze the association between the results of genotyping and the occurrence of CI.</p><p><b>RESULTS</b>The cerebral infarction group and the control groups showed significant differences in the allele and genotype frequencies of rs189897 and rs2212020 (P<0.05). The A-C haplotype was the protective factor against CI, and the subjects with the haplotype had a lowered risk for CI than those without this haplotype (0.13:1).</p><p><b>CONCLUSION</b>rs189897 and rs2212020 in ITGA9 gene are closely related to CI, and its A-C haplotype is the protective factor against CI.</p>
