For simply research, HMM assume the time of continuous states staying obey geometry distributing.

为了研究方便，隐马尔科夫模型假设连续段长分布的时间是服从几何分布，但这与真实的分布规律并不相符。

Gene mutations were detected in 25 patients and a 18-year-old girl among 16 families. Trinucleotide repeats of CAG were 73～79. The fragments of abnormal alleles were 380～402bp, and all patients were heterozygous. The copy numbers of normal alleles were 18～40, fragments from 202～270bp. SCV reduction was much obvious compared to MCV, MCV and SCV in lower limb ?ere much more slow than that in upper's. BAEP, VEP were also delayed in latency. The anticipation in parental sex bias were much more obvioius than that in matental's. Cerebellar ataxia was most severe, the next were dysarthria and bulging eyes. Amytrophy was seen only in bed ridden patients. Cerebellar atrophy was more severe than brain stem, cord atrophy was n't observed in all MJD.

结果检出10个家系25例病人及1例症状前18岁女孩有MJD基因突变，CAG三核苷酸重复73～79次，异常等位基因片段长380～402bp，均为杂合子；正常人CAG三核苷酸重复18～40次，等位片段长200～270bp，电生理发现MJD的SCV减慢比MCV明显，而下肢的MCV、SCV又较上肢明显，BAEP、VEP均有不同程度的潜伏期延长或波的异常；MJD的父亲遗传早于母亲，进展也较块，临床以小脑性共济失调为突出症状，其次为构音障碍、突眼等，肌肉萎缩仅见于晚期病人；MRI示小脑萎缩较明显，脑干萎缩并不严重，未见明显的颈髓萎缩。

The result of sequence analysis indicated that the length of cDNA and DNA fragments of Lectin gene and the length of cDNA and DNA fragments of Pectate Lyase gene were 508 bp,575 bp,1,316 bp and 1,858 bp respectively.The DNA fragment of Lectin gene had a intron,whose length was 67 bp .The DNA fragment of Pectate Lyase gene had 3 introns,whose lengths were 90 bp,83 bp,and 370 bp respectively. All these four introns sequences followed the rule of GT-AG.

通过序列分析得知，香蕉凝集素基因cDNA片段长508 bp；香蕉凝集素基因DNA片段长575bp，有一个长为67bp的内含子；香蕉果胶裂解酶基因cDNA片段长1，316bp；香蕉果胶裂解酶基因DNA片段长1，858bp，有三个内含子区，分别长90 bp，83 bp和370bp；在总共的四个内含子序列中，分别都符合GT-AG规则。

Result: The length of intraorbital segment of anterior ethmoidal artery was 5.16±1.24 mm,and its diameter was 0.56±0.17 mm;the length of intraorbital segment of posterior ethmoidal artery was 9.08±2.29 mm,with diameter 0.37±0.14 mm.

结果：筛前动脉眶内段长(5.16±1.24)mm，管径为(0.56±0.17)mm；筛后动脉眶内段长(9.08±2.29)mm，管径为(0.37±0.14)mm。

The sequence of amino acid of clone CR271 was highly homologic (61% identify and 76% similarity) to blight resistance gene Xal of rice to Xanthomonas oryzae pv. Oryzae. All other fragments showed significantly amino acidhomology to the NBS-LRR type resistance gene that have been cloned. The length of JR2 and JR3 fragments were 1321bp and 896bp respectively, which did not showed significantly homology on the level of amino acid and nucleotide acid to the sequences that have been known.

其中CR271与水稻白叶枯病抗病基因Xa1(AB002266)氨基酸同源性有61％相同，76％相似，其它片段与已克隆的NBS-LRR类抗病基因同源片段都具有较高的同源性；所获得的右翼序列JR2DNA片段长为1321bp，JR3DNA片段长为896bp，此两片段在核苷酸水平及氨基酸水平上均未找到有显著同源的序列。

Second, residues in the reactive site of the inhibitor were replaced by the consensus substrate recognition sequence of furin, namely, Arg at P_1, Lys at P_2, Arg at P_4 and Arg at P_6. In addition, the P_7 residue Asp was substituted with Ala to avoid possible electrostatic interference with furin inhibition. Finally, the extra N and C terminal residues beyond the doubly conjugated disulfide loops were further truncated. However, all resultant synthetic peptides were found to be temporary inhibitors of furin and kexin during a prolonged incubation, with the scissile peptide bond between P1 and P'1 cleaved to different extents by the enzymes.

高活性、低分子量的furin酶抑制剂有可能发展成为新型的抗细菌内毒素和抗病毒感染的药物，我们以绿豆胰蛋白酶抑制剂Lys片段长链22肽为模板，设计了一系列能抑制furin和kexin活性的突变体，采用如下三种方法逐步优化：一、去除Lys片段长链三对二硫键中的一对，用Ser替换Cys，减少可能存在的二硫键错误配对；二、抑制剂的活性中心根据furin底物的专一性逐步改变，即P1、P2、P4和P6位分别变为Arg、Lys、Arg和Arg，同时为了避免P7 Asp和P6 Arg之间可能存在的相互作用，将P7位Asp替换为Ala；三、将两对二硫键形成的双环的外面5个氨基酸残基去除。
