RESUMO
The 14th Asia Pacific Burn Congress, the 18th Chinese Symposium on Burn Medicine, and the 2023 Huaxia Burn Forum was held successfully in Chongqing from September 13th to 16th, 2023. More than 1 000 participants from more than 10 countries and regions attended the congress, including over 100 overseas experts. The theme of the congress was homage, heritage, and innovation, and three-day academic exchange was held in the form of academician forum, keynote forum, and seven thematic sub-forums focused on the hot spots and difficulties in the fields of burns, trauma, wound repair, and related fields. The congress was compact, comprehensive, in-depth, and fruitful, with warm atmosphere at the meeting site.

Peanut is one of the most important oil crops worldwide. We used insertion-deletion (InDel) markers to assess the genetic diversity and population structure in cultivated peanut. Fifty-four accessions from North China were genotyped using 48 InDel markers. The markers amplified 61 polymorphic loci with 1 to 8 alleles and an average of 2.6 alleles per marker. The polymorphism information content values ranged from 0.0364 to 0.9030, with an average of 0.5038. Population structure and neighbor-joining (NJ) tree analyses suggested that all accessions could be divided into four clusters (A1-A4), using the NJ method. Likewise, four subpopulations (G1-G4) were identified using STRUCTURE analysis. A principal component analysis was also used and results concordant with the other analysis methods were found. A multi-linear stepwise regression analysis revealed that 13 InDel markers correlated with five measured agronomical traits. Our results will provide important information for future peanut molecular breeding and genetic research.

Type 1 diabetes mellitus (DM1), autoimmune thyroid disease (ATD) and autoimmune gastritis often occur together forming the so-called autoimmune polyendocrine syndrome (APS) type 3. Thyroid autoimmunity is evident in up to one third and gastric autoimmunity in up to a quarter of patients with DM1. Also relatives of DM1 patients, particularly mothers, have higher frequencies of these autoimmune conditions. Vice versa, gastric autoimmunity is present in one third of ATD patients and islet autoimmunity in one out ten. The BB-DP rat, the NOD mouse, the OS chicken and the neonatal thymectomy mouse model are animal models of APS type 3. In these models the autoimmune destruction of the various target tissues has been shown to be a multi-step process in which several genetic polymorphisms need to converge to induce both local anomalies in the target gland and anomalies in the immune system. With regard to environmental factors, excess iodine is well known to elicit/aggravate thyroid autoimmunity in these animal models. Screening DM1 patients and their relatives (particularly females) for thyroid autoimmunity is recommended. If positive, excess iodine should be avoided and thyroxin treatment considered. Whether autoimmune thyroiditis and autoimmune gastritis patients should be screened for islet Ab is not clarified.
