A high-performance SNP panel developed by machine-learning approaches for characterizing genetic differences of Southern and Northern Han Chinese, Korean, and Japanese individuals.

Population stratification analyses targeting genetically closely related East Asians have revealed that distinguishable differentiation exists between Han Chinese, Korean, and Japanese individuals, as well as between southern (S-) and northern (N-) Han Chinese. Previous studies offer a number of choices for ancestry informative single nucleotide polymorphisms (AISNPs) to discriminate East-Asian populations. In this study, we collected and examined the efficiency of 1185 AISNPs using frequency and genotype data from various publicly available databases.

[Traditional use of Paris polyphylla and its active components].

This paper reviewed the traditional use of Paris polyphylla and its active components, aiming to provide reference for the development and utilization of this plant. It was found that P. polyphylla has been used as a medicinal plant by eight ethnic minorities.

The Prevalence and Associated Factors of Periodontal Disease among 35 to 44-year-old Chinese Adults in the 4th National Oral Health Survey.

Objective: To assess the current periodontal status of 35 to 44-year-olds from the Chinese population and to analyse potential influence factors on periodontal disease.

Methods: The data of subjects were collected from both urban and rural areas of all 31 provinces, autonomous regions and municipalities of the mainland of China, as part of the 4th National Oral Health Survey. All subjects were aged 35 to 44 years old.

[The association between glucocorticoid receptor gene G1666T polymorphism and cerebral infarction in Chinese].

Objective: To ascertain whether the human glucocorticoid receptor (GR) gene polymorphism is associated with cerebral infarction (CI) and essential hypertension (EH) in Chinese.

Methods: This is a case-control study of Chinese DNA samples abstracted from 163 subjects. The samples were analysed by a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) to determine the intron 4 variant of human GR gene.
