作者用高效液相层析（ＨＰＬＣ）法测定了汉、回、维吾尔（维）、哈萨克（哈）族新生儿胎儿血红蛋白（ＨｂＦ）中~Ｇγ／~Ａγ、~Ａγ~Ｉ／~Ａγ~Ｔ比值，共３７２例，其中汉族和回族各１０２例、维族９９例、哈族６９例。％~Ｇγ（~Ｇγ／~Ａγ）均值：汉、回、维、哈族分别为６６．８３％、６８．３３％、７０．４４％和６９．７０％。低~Ｇγ者（＜５０％）４例：其中回族３例、哈族１例。高~Ｇγ者（＞８０％）２５例：汉和哈族各５例、回族４例，维族１１例。发现~Ａγ~Ｔ杂合子９９例分别为：汉２１例、回２３例、维２６例、哈族２９例。４个民族各发现１例~Ａγ~Ｔ纯合子。％~Ａγ~Ｉ（~Ａγ~Ｉ／~Ａγ~Ｔ）均值：汉５６．８３％、回５５．５８％、维５０．９４％、哈５４．６８％。~Ａγ~Ｔ基因频率依次为０．１１３、０．１２３、０．１４１及０．２２５。两例比值异常者（１例维族高~Ｇγ８５．４２％、~Ａγ~Ｔ杂合体。１例回族低~Ｇγ４３．４％，~Ａγ~Ｉ纯合体）经γ基因图谱分析，确定高~Ｇγ值者γ珠蛋白基因型为－~Ｇγ－~（ＡＧ）γ－~Ａγ~Ｔ（~Ａγ~Ｉ）－／－~Ｇγ－~Ａγ~Ｉ，（~Ａγ~Ｔ）－；低~Ｇγ值者为－~（ＧＡ）γ~Ｉ－／－~Ｇγ－~Ａγ~Ｉ－。
The authors used high performance liquid chromatography (HPLC) method to determine the expression of ~ Gγ / ~ Aγ, ~ Aγ ~ I / ~ Aγ ~ T in fetal hemoglobin (HbF) of Han, Hui, Uygur and Kazak Ratio, a total of 372 cases, of which 102 cases of Han and Hui, Uygur 99 cases, 69 cases of Kazakh. The mean values of% ~ Gγ (~ Gγ / ~ Aγ) were 66.83%, 68.33%, 70.44% and 69.70% for Han, Hui, Wei and Ha nationality respectively. Low ~ Gγ (<50%) 4 cases: 3 cases of Hui, Kazak 1 case. High ~ Gγ (> 80%) 25 cases: 5 cases of Han and Ha nationality, 4 cases of Hui nationality, Uygur 11 cases. The results showed that there were 99 cases of ~ Aγ ~ T heterozygote in 21 cases, 23 cases in back, 26 cases in dimension and 29 cases in Kazakh. One patient in each of the four ethnic groups found ~ Aγ ~ T homozygotes. Mean values of% ~ Aγ ~ I (~ Aγ ~ I / ~ Aγ ~ T) were 56.83% in Han, 55.58% in Han, 50.94% in dimension and 54.68% in Ha. ~ Aγ ~ T gene frequency were 0.113,0.123,0.141 and 0.225. Two cases of abnormal ratio (1 Uighur ~ Gγ85.42%, ~ Aγ ~ T heterozygous, 1 Hui low ~ Gγ43.4%, ~ Aγ ~ I homozygous) The value of γ-globin genotype was - ~ Gγ- ~ (AG) γ- ~ Aγ ~ T (~ Aγ ~ I) - / - ~ Gγ- ~ Aγ ~ I, The value of - ~ (GA) γ ~ I - / - ~ Gγ- ~ Aγ ~ I-.
