Objective To evaluate the predictive value for serum albumin-globulin ratio （A/G） for the risk of Kawasaki disease （KD） in febrile children. Methods In this single-center retrospective cohort study， the big-data platform of a certain third-tier A-level hospital was employed. Clinical and laboratory data of 432 febrile children aged 0-16 were collected. The children were divided into 4 groups based on the quartiles and median of their serum A/G ratios. The correlation between the A/G and the risk of KD was analyzed. Results The total incidence rate of KD in 432 children with fever was 14.4% （62/432）.A significant negative correlation was observed between the A/G and the risk of KD. For each increase of 0.1 in the A/G， the risk of KD was decreased by 18% （OR=0.82， 95% CI 0.76-0.88， P < 0.001）. Subgroup analysis showed a consistent negative correlation between the A/G and KD risk across different ages， genders， and biochemical markers. Conclusions A/G may be a useful biomarker for assessing the risk of KD in febrile children. As the A/G increases， the risk of KD is gradually decreased. This finding has potential clinical application value for early diagnosis and risk assessment of KD.

African swine fever virus (ASFV) infection leads to a mortality rate of up to 100%, causing devastating disasters to the pig industry. Understanding the ASFV infection and replication is therefore of great importance. ASFV has more than 150 open reading frames, among which the inner coat protein p17 encoded by the D117L gene is involved in the formation of the icosahedral structure of the virus. However, little is known about the mechanism how p17 regulates host cell function. In this study, the potential host proteins interacting with ASFV p17 were screened by immunoprecipitation technique combined with protein profiling analysis. The interactions of p17 with mitochondrial membrane protein TOMM70 and heat shock protein HSPA8 were confirmed by co-immunoprecipitation technique and laser confocal experiments. This study provides important information for further exploring the function of p17 during ASFV infection.
