The study show the predominating emm sequence type of GAS in some regions of China is emm1, emm18, emm12, emm69 and emm110, this result provides an useful guideline to develop the M-type specific vaccine for RF in a specific area of endemicity. 我国部分地区A群链球菌emm基因分型主导型为emm1、18、12、6 9、110等菌型。
In areas with high HBV endemicity, perinatal transmission is the main route of transmission, whereas in areas with low HBV endemicity, sexual contact amongst high-risk adults is the predominant route. 在HBV的高毒力区内，围产期是最主要的感染途径，而在低HBV毒力的地区，高危人群之间的性是传染的主要传播途径。
As a part of the folk song's language, the extra words have strengthened the popularity and endemicity of the lyric language, and have enhanced the expression of the music language. 摘要衬词作为民歌语言的一部分，加强了歌词语言的民间性、地方性，增强了音乐语言的表现性。
