All cases were diagnosed as BH4 deficiency by analysis of urinary pterins profile, BH4 loading test, and determination of dihydropteridine reductase in RBC.

所有患者均经尿蝶呤谱分析、BH4口服负荷试验及红细胞二氢蝶呤还原酶测定，确诊为BH4缺乏症。

For example, in the separations of purines, pyrimidines and pterins to these compounds on MSP, hydrogen-bonding interaction played leading roles besides hydrophobic interaction.

例如，在厚朴酚键合硅胶固定相（MSP）中分离嘌呤、嘧啶及蝶呤时，除了疏水性作用外，氢键作用还发挥着重要作用。
