The result of uroscopy of the proband was strong positive. There was a novel deletion mutation of c.876-877 del TC in the coding region of exon 6 of IDS gene, which was a hemizygous mutation. However, the mutation of his mother and sister was a heterozygous mutation. Detection of the exon 6 of IDS gene showed that the mutation was not found among normal controls and other patients with MPS I, IV, and VI other than MPS II. Homology comparison of amino acid sequences from different species showed that the phenylalanine glutamine of the mutation site of c.876-877 del TC located in p.292-293 was highly conserved. The activity of IDS enzyme of the proband was only 2.3 nmol/4 h/mL, which was much lower than normal; but the activity of IDS enzyme of his father, mother and sister was 641.9 nmol/4 h/mL, 95.8 nmol/4h/mL and 103.2 nmol/4h/mL, respectively.

结果显示：先证者尿检呈强阳性；其IDS基因exon 6编码区内存在c.876-877 del TC新缺失突变，为半合子突变，而其母、其姐为杂合突变；正常对照和其他非II型MPS患者的IDS基因exon 6的检测结果均未发现该突变；不同物种氨基酸序列的同源性比对显示： c.876-877 del TC突变所在的位置即p.292-293的苯丙氨酸谷氨酰胺高度保守；酶活性测定的结果显示：先证者的IDS酶活性仅为2.3 nmol/4 h/mL，大大低于正常值，而其父的为641.9 nmol/4 h/mL，其母的血浆酶活性为95.8 nmol/ 4h/mL，其姐的为103.2 nmol/4 h/mL。

During the painful stimulus itself, there was increased activation in the right amygdala and decreased activation in the periaqueductal gray matter and rostral anterior cingulate and prefrontal cortices, areas responsible for cortical and subcortical pain modulation, in the depressed relative to nondepressed subjects.

在痛觉刺激本身时，右杏仁体的活性增加，而导水管周围灰质的活性是下降的，且喙侧前扣带回与额前皮质，负责皮质与亚皮质疼痛调控的区域，其活性相较于非忧郁受试者来说是下降的。

The soluble microbial products formation process by microorganisms from activated sludge of membrane bioreactor and biodegradation process by other microorganisms, pseudomonas putida, under oligotrophic environment were discussed, respectively.

以碳源作为限制营养，研究了贫营养条件下膜生物反应器中活性污泥微生物产出溶解性微生物产物和非来源微生物恶臭假单胞菌降解活性污泥SMP的过程。

The antitumor and antifungal activities of BFA on four human tumor cell lines and six phytopathogenic fungi were tested,and the minimum inhibitory concentrations on sensitive fungi were tested too.

进一步研究表明，BFA对人Burkitt's 淋巴瘤细胞株Raji、人肝癌细胞株HepG2和人非小细胞肺腺癌细胞株A549具有较强的抑制活性，对植物病原真菌黑曲霉和杨桃炭疽菌等具有抑菌活性。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。

Four goats (42.4±3.5 kg) surgically fitted with cannulas in common bile duct and abomasal were used in 4×4 Latin square design and randomly fed diets contained 20%, 30%, 40% or 50% of starch to determine the effects of rumen escape starch, by altering dietary starch concentration, onα-amylase secretion in goats. Increasing rumen escape starch results in a quadratic increase in pancreaticα-amylase secretion.
