Objectives: Genetic characteristics were investigated based on short tandem repeat (STR) data to assess the relationship between two Vietnamese Bouyei populations in Vietnam.
Methods: We collected hair and buccal swab samples from two separate Bouyei populations in the mountainous region of Northern Vietnam, which are the Bo Y in Ha Giang Province and the Tu Di in Lao Cai Province. The study included data of 23 autosomal and 27 Y-chromosome STRs loci of 96 unrelated participants from a total Vietnamese Bouyei population of under 3300 individuals.
Results: The results showed that these STR markers are valuable for differentiation of individuals and human genetic studies in Vietnamese Bouyei populations. Genetic analysis indicated that Tu Di and Bo Y people were from the same Bouyei population in China.
Conclusions: The results supported the official historical records of the region and the classification of the Vietnamese government. Furthermore, the genetic data provided in this study will be helpful in investigating the genetic genealogy evolution and settlement or migration patterns of the Bouyei populations in Vietnam.

In this research, a self-developed panel comprising 22 X chromosomal multi-InDels and one X-STR was used to explore the genetic polymorphisms and forensic characteristics of these loci in Guizhou Miao and Guizhou Bouyei populations. Besides, genetic affiliations among Guizhou Miao, Guizhou Bouyei and Guizhou Han populations were investigated using principal component analysis, STRUCTURE and machine learning methods. The findings indicated that these loci in the male and female samples had comprehensive discrimination powers greater than 0.

Article Synopsis
- China has significant ethnic diversity, making whole genome variation data essential for population genetics and precision medicine, yet research on ethnic minority genomes is limited.
- The Guizhou Multi-ethnic Genome Database (GMGD) provides whole genome sequencing data from 476 individuals across 11 ethnic minority groups in Guizhou Province, featuring over 16 million variants, including many novel ones not found in existing databases.
- GMGD allows researchers to explore genetic variations with tools for mutation searches and a genotype-imputation function, making it the largest and most diverse genome-wide database available for these ethnic groups, accessible online.

Pathogen‒host adaptative interactions and complex population demographical processes, including admixture, drift, and Darwen selection, have considerably shaped the Neolithic-to-Modern Western Eurasian population structure and genetic susceptibility to modern human diseases. However, the genetic footprints of evolutionary events in East Asia remain unknown due to the underrepresentation of genomic diversity and the design of large-scale population studies. We reported one aggregated database of genome-wide SNP variations from 796 Tai-Kadai (TK) genomes, including that of Bouyei first reported here, to explore the genetic history, population structure, and biological adaptative features of TK people from southern China and Southeast Asia.

Article Synopsis
- A study in Yunnan Province from 2013 to 2019 evaluated the rubella IgG antibody levels among rural women aged 20-49 participating in the National Free Preconception Health Examination Project, revealing a 24.36% negative rate for immunity.
- Only 2.64% of these women had received the rubella vaccine, and the negative rate was influenced by age and education level, being higher among ethnic minority women compared to Han women.
- The findings highlight a significant susceptibility to rubella among childbearing-age women in rural areas, indicating a need for increased vaccination efforts to minimize the risk of rubella infection during pregnancy.
