To further investigate the molecular genetic characteristics of enzomatic nasal tumor vi-rus of goats(ENTV-2)in Yunnan Province,this study measured and analyzed the entire genome of ENTV-2 in Yunnan Province.The results showed that the complete genome sequence of the EN-TV-2 YN2023 strain(GenBank accession number:PP682590.1)was successfully obtained.The YN2023 strain has a total length of 7 307 bp and a typical structure of 5'-M5-gag-pro-pol-env-M3-3'.Whole genome sequence homology analysis showed that the nucleotide homology between YN2023 strain and 41 reference strains ranges from 85.3％to 95.5％.The whole genome evolution-ary tree indicates that the YN2023 strain is closely related to the prevalent strains in China,with certain genetic diversity and geographical clustering.The analysis of the gag gene evolutionary tree shows that the gag gene cluster of YN2023 strain is on a branch of the ENTV-2 gag gene,and YN2023 is clustered on the same small branch as enENTV-FJ1 and GDQY2017 strains,with the closest genetic relationship.The env gene evolutionary tree shows that YN2023 is on the same branch as GDQY2017,GDZJ2022,ENTV-2CHN1-6,ENTV-FJ1,and ENTV-FJ3,and is also on the same branch as GDQY2017,indicating a close genetic relationship.Recombination analysis showed that the YN2023 strain underwent a potential recombination event between breakpoint positions 6378-7478 bp,with the Chinese Chongqing strain enENTV-CQ1(OR669623.1)as the primary parent and the Chinese Sichuan strain BH(MT254062.1)as the secondary parent.This study enriches the genomic information of the ENTV-2 strain in Yunnan Province and provides data sup-port for the genetic variation of ENTV-2 in Yunnan Province.

Objective:To explore the predictive value of Red Blood Cell Distribution Width (RDW) in predicting the prognosis of patients with Extracorporeal Membrane Oxygenation (ECMO).Methods:The clinical data of patients undergoing ECMO admitted to Intensive Care Unit of Sichuan Provincial People’s Hospital from January 2015 to January 2020 were retrospectively analyzed. Patients were divided into the survival group and death group according to the prognosis during ICU hospitalization. The patients' basic data , acute physiology and chronic health score system Ⅱ (APACHE Ⅱ), RDW and activated partial thromboplastin time (APTT) at 72 hours after treatment with ECMO were compared between the two groups. Univariate and Logistic regression multivariate analyses were used to analyze the prognostic factors of patients with ECMO, predictive models and death warning scores were established. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficacy of RDW and death warning scores for the prognosis of patients with ECMO.Results:A total of 71 patients with ECMO who met the inclusion criteria were included, including 38 patients in the death group and 33 patients in the survival group. The age, APACHE-Ⅱscore, 72 h RDW and 72 h APTT in the death group were higher than those in the survival group. Respectively, the hospitalization time of ICU in the death group was significantly lower than that in the survival group ( P< 0.05). Logistic regression analysis showed that APACHE-Ⅱscore ( OR=1.117, P=0.047)、72 h RDW( OR=1.102, P=0.029) and 72 h APTT ( OR=1.049, P=0.029) were independent risk factors for death in patients with ECMO. ROC curve analysis showed that the area under ROC curve (AUC) of the APACHE-Ⅱ, score 、72 h RDW and 72 h APTT were 0.691, 0.691 and 0.632( P<0.05), Respectively, the combined AUC was 0.764, the sensitivity was 0.526, and the specificity was 0.909. The death warning score of patients with ECMO was established according to the Predictive model , which is less than 2 points with low risk of death and more than 2 points with high risk of death. The area under the ROC curve of death warning score is 0.8, the sensitivity is 0.607 and the specificity is 0.923. Conclusions:The RDW at 72 hours after treatment with ECMO has a good value in predicting the prognosis of patients with ECMO. Besides, a greater predictive value for the prognosis of patients with ECMO by combining 72 hours RDW, 72 hours APTT with APACHE-Ⅱscore than that of any separate indicator.

Objective To study the clinical characteristics of the adult onset Still's disease(AODS),its concomitant symptoms,and misdiagnosis.Methods To analyze retrospectively 12 adults who were diagnosed bosh by clinical treatment and laboratory examination as AODS patients.Results 12 cases suffered from fever,9 cases from dermatitis and arthralgia,3 cases from muscle pains,3 cases from enlarged liver,4 cases from enlarged spleen,3 cases from enlarged liver and spleen,and 3 cases from abdomen pain.Conclusion AODS does not have special symptoms in its early stage.Its complexity often results in a missdiagnosis.
