Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.
流纹质岩石总体具富碱、富硅、富铝,贫钙、贫镁特征,其Rb、Th等元素的含量较高,而Ba、Sr、Ti、P等元素含量则明显偏低,并具显著的铕负异常(εEu=0.16'0.44),岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。

A set of spectific primers was syn thesized according to HBV DNA sequence of Chinese strain, the whole X region was amplified by PCR method from the serum of 9 patients with chronic HBV infection , and then the PCR products were subcloned into pGEM Teasy vectors. Clones were randomly selected to be sequenced. Comparison of the cloned sequence was made to find the difference. After being compared, each sequence of selected clones is o f difference. The point mutation scattered through X region. Deletion mutations were detected in 19 clones of 37(51.4%), which caused different carboxyl endings of X protein. There is a hot region (after 123 aa code) where deletion mutation frequently happens.
以中国株HBV基因序列为依据,设计特异性多聚酶链反应引物,自9例慢性HBV感染患者血清中扩增HBV X基因,克隆入pGEM Teasy质粒,随机挑选克隆进行D NA测序以确定病毒的变异程度。37例测序结果提示来源于不同患者HBV X基因序列高度保守,但每个序列均不一致。X区除了存在广泛的碱基点替换突变外,序列的缺失突变占测序克隆总数的51.4%(19/37);氨基酸缺失及移框突变多发生于123位氨基酸残基之后,可导致X蛋白多种羧基端形式。
