宁夏回、汉族舌运动类型的遗传学研究

Genetic Study on Tongue's Movement Types of Hui and Han Nationalities In Ningxia

目的调查分析宁夏回、汉族舌运动类型的遗传学特征。方法采用随机整体抽样的方法对宁夏汉族(共808例,男412例,女396例)和回族(共492例,男312例,女180例)人群的舌运动类型(卷舌、翻舌、叠舌、三叶舌)进行问卷调查。结果卷舌、翻舌、叠舌、三叶舌出现率在汉族依次为74.75%3、5.27%2、6.11%、2.35%;回族依次为81.30%2、6.02%、28.25%4、.47%。回族在卷舌、叠舌、三叶舌出现率均高于汉族,翻舌出现率低于汉族;宁夏回、汉族之间卷舌、三叶舌及翻舌的出现率有统计学意义(P<0.05,P<0.01)。结论1.宁夏回、汉族舌运动类型在性别间没有统计学意义;2.卷舌、翻舌、叠舌、三叶舌4种舌运动类型有明显相关性。

Objective To investigate tongue＇s movement types between Hans and Huis in Ningxia and to analyze the features of them. Methods A randomized and stratified sampling study was conducted and 4 types of tongue＇ s movement （ rolling, twisting, folding and clover-leaf tongues ） were investigated among 808 Hans （412 male and 396 female） and 492 Huis （312 male and 180 female ） in Ningxia. Results Hans showed the rolling , twisting, folding and clover- leaf tongues with the frequencies of 74.75%, 35.27%, 26.11%, and 2.35% ; respectively. While Huis with the frequencies of 81.30%, 26.02%, 28.25% and 4.47%. Huis showed a higher frequencies on rolling, folding and clover - leaf tongues, but a lower twisting tongues than Hans. Hans had significant difference from Huis in the frequency of roiling, clover- leaf tongue and had important difference from Huis in the frequency of twisting. Conclusion There is no significant difference in tongue＇s movement types in sex between Han and Hui, but there are correlations in 4 types of tongue＇s movement.
