Objective: With umbilic blood from the mature newborns, to screen CpG-ODN, which can markly boost up the immunity response, from some designed CpG-ODNs; to compare the effect of CpG-ODN on the lymphopoiesis of umbilic blood from the premature, mature newborns and the peripheral blood from the adults; to observe the infulence of CpG-ODN on the immune function of the pregnant mices and their newborns, the immune-inhibited and aged mices.

目的：设计含非甲基化胞嘧啶和鸟嘌呤的寡聚脱氧核糖核苷酸，以期用足月新生儿脐血筛选出具有较强免疫增强作用的CpG-ODN；比较CpG-ODN对新生儿脐血和成人外周血单个核细胞的增殖效应；观察CpG-ODN对孕鼠及其新生鼠、免疫抑制鼠和老年鼠体液免疫功能的影响。

Objective To study the relationship between CTG repeat frenquency in MTPK gene and the change of ECG in patients with myotonic dystrophy.

目的 研究强直性肌营养不良症患者的肌强直蛋白激酶基因中胞嘧啶、胸腺嘧啶、鸟嘌呤CTG）三核苷酸重复次数与DM病人心电图改变的关系。

Objective: Design and synthesize the oligodeoxynucleotides containing unm- ethylated CpG dinucleotides to screen out the optimal CpG-ODN that could markedly enhance the immune function of cord blood mononuclear cells in health newborns. Moreover, observe the action of CpG-1826 (5'-TCCATGACGTTC CTGACGTT-3') as the immune adjuvant of the hepatitis B vaccine on the pregnant mice and their neonatal mice.

目的：设计并合成含非甲基化胞嘧啶和鸟嘌呤二核苷酸的寡聚脱氧核糖核苷酸，以期筛选出对新生儿脐血单个核细胞免疫刺激作用较强的CpG-ODN；观察不同剂量CPG-1826(5'-TCCATGACGTTCCTGACGTT-3')辅助乙肝疫苗免疫孕鼠及仔鼠的作用。

This kind of configuration suits the multi-nucleotide chain's purine pyrimidine alternate area. in 1989, the American scientists with scanning tunnel electron microscope law visual observation double helix DNA double helix DNA ︰ in 1952, Austrian lineage US biology chemist Zha Qiefu (E.chargaff,1905-) have determined in DNA 4 kind of basic group content, the discovery gland fat ling and thymine quantity are equal, the bird fat ling and cytosine quantity is equal.

这种构型适合多核苷酸链的嘌呤嘧啶交替区。1989年，美国科学家用扫描隧道电镜法直接观察到双螺旋DNA 双螺旋DNA︰1952年，奥地利裔美国生物化学家查伽夫（E.chargaff，1905—）测定了DNA中4种碱基的含量，发现其中腺膘呤与胸腺嘧啶的数量相等，鸟膘呤与胞嘧啶的数量相等。

Thus, nucleotides in DNA or RNA are typically called 'bases'; consequently they are commonly referred to simply by their purine or pyrimidine original base components adenine, cytosine, guanine, thymine.

因此，核苷酸的DNA或RNA通常是所谓的'基地'；因此，他们通常被称为只要他们嘌呤或嘧啶在原有的基础上组成部分腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
