Mean time of EA was (48.6±32.8)ms before onset of the surface QRS. The length of conduction pathway was (2.6±0.9)cm. The ablation catheter mapping showed perfect match in at least 11 of 12 leads at the EX (≥11/12), but not at the EA (≤10/12) with pace mapping during sinus rhythm. Purkinje potentials were mapped at EA and CP in all cases, but only one case at EX, and diastolic potentials were mapped at EA in 2 cases during ILVT. All cases were successfully ablated by area ablation at EA or/and line ablation at CP during sinus rhythm. None suffered a recurrence during (12±6) months follow-up.

In this paper, we studied M. meretrix ferritin, cathepsin B and caspase genes, which are involved in clam larval shell formation, nutrition, metabolism and apoptosis, respectively. We have cloned the three genes, investigated the temporal and spatial expression profile both at gene and protein level in trochophore (L1), D-veliger (L2), pediveliger (L3) and postlarvae (L4). The potential roles of these proteins were analyzed with specific inhibitors during larval development. Firstly, embryos were found developed into trochophore-like larvae with no shell if cultured at gastrula stage in artificial seawater without iron. Shell-like structures were formed only in the presence of iron. The larvae which had been transferred at L1 stage into ASW developed normal shell. This indicated that iron and iron associated protein are important for larval shell formation. The EST sequence which is homologous with ferritin, which is a principal iron metabolic protein, was selected from the M. meretrix cDNA library. The full-length of ferritin subunit cDNA was cloned by RACE. The results of real-time PCR revealed that the MmeFer mRNA expression changed before and after the larval shell formation.
本论文以文蛤幼虫为研究对象,分别对文蛤幼虫发育过程中贝壳形成相关的铁蛋白、营养及变态相关的组织蛋白酶B及变态过程中细胞凋亡相关的caspase三个基因进行了克隆,分析了基因及编码蛋白在担轮幼虫期(L1)、D形幼虫期(L2)、壳顶幼虫期(L3)和稚贝期(L4)的时空表达特征,解析了其可能的功能,并研究了相应酶类的特异性抑制剂作用对幼虫发育过程的影响,进行了目标蛋白的功能验证,详述如下:研究结果显示,在文蛤胚胎发育到原肠胚时放入不含铁离子的人工海水中培养,发育成无壳的畸形,随着人工海水中铁离子添加浓度的升高,幼虫长出壳状组织接近正常状态;而发育到L1期幼虫放入不含铁离子的人工海水中培养却可以发育出正常的壳,推测铁和铁代谢相关蛋白在幼虫贝壳初始形成有重要的作用。

Results We obtained a lysogenic bacteriophage MZTP01with clear plaque and 1 mm diameter. Fragment D with 2362bp (Genebank No. AY639599) was obtained after the phage DNA hydrolyzed by HindⅢ/EcoRⅠ. Among fragment D, the pep gene with molecular weight of 47 kDa and length of 1101bp was cloned and expressed. Recombinant M15 (pQE30pep) was built and overexpressed in Escherichia coli with a 47kDa clear band. At the same place a clear band was observed by Western blot. Judging from the time course expression, we could conclude that PEP protein produced at 1 hour after induction and then increased gradually. PEP protein was mainly in the form of inclusion body in the recombinant and slowed the growth speed of host. Homologous comparison of PEP protein from phage MZTP01 with other PEPs from BLAST were that phage MZTP01 PEP protein had 100% homologe with that of Escherichia coli K12, and most of others took the similarity in the range between 37%~84%.
