A mean age was 11.3 months （range from 2d to 13 years old）. 31.87% of them presented symptoms in the infant period. Main symptoms were vomiting and upper abdomen pain. Midgut volvulus presented distention and tenderness. Intestinal gangrene presented haematemesis and melena.

诊断主要依据出生3～7天后量胆汁样呕吐，腹部立位平片及上消化道气钡造影、钡剂灌肠，B超、CT、MRI亦有意义。

The oxidase system includes both membrane-bound and soluble cytosolic proteins. The primary feature of this enzyme is stimulus-dependent activation and which mechanism is the phosphorylation and translocation of a complex of cytosolic factors to the membrane, where they associate with a flavocytochrome enzyme.The fully assembled complex functions as an electron transport system,moving electrons from cytosolic NADPH to molecular oxygen to form superoxide anion（O2-）, which, along with subsequent reactive products called respiratory burst,exerts microbicidal and cytotoxic activities.

此氧化酶体系包括膜结合的和可溶的胞浆蛋白，其主要特征为依赖刺激而活化，机制为复合体的胞浆因子磷酸化并转位至膜，在这里与细胞色素酶相关联，组装完全的复合体在功能上作为一个电子转运体系，从胞浆NADPH转移电子给分子氧形成超氧阴离子（O2-），伴随着接下来的活性物质产生，也叫呼吸爆发，发挥抗菌和抗细胞毒素的活性。

Results totally 287 strains were isolated from the 256 positive samples , and the gram-negative bacilli were 225(78.4%,), the gram-positive coccus were 41(14.3%), snd the monilia were 21(7.3%).the distributions of clinical bacteria were respiratory tract(63.4%),urinaryract(7.0%),secretion(includingwound .3%),blood(5.9%),stool(5.2%), pucture fluid(4.9%), and other sites(7.3%). of all isolating bacterium,from the first to the fifth were ps.aeruginosa(19.5%),k.pneumoniae(16.7%), e.coli(14.3%), a.baumannii(11.8%) and psemal (10.1%).resistant rates of methecillin-resistant s.aureus,methecillin-resistant coagulase-negative staphylococci and vancomycin-resistantwere 88.2%、70.0% and 11.1% respectively;the incidence of e.coli and k.penumoniae produce extended speutrum beta-lactamase were 68.6%和65.2%, 44.6% of ps.aeruginosa isolates were resistant to imipenem; the highest examining rate of 21 kinds of monilia was candida albicans (66.7％),resistant rate of candida albicans to fluconazole and amphotricin b was 51.3％ and 1.3%.

结果 在254份检出细菌阳性标本中共培养出287株细菌，其中革兰阴性杆菌225株（78.4％），革兰阳性球菌41株（14.3%），念珠菌21株（7.3%），检出菌来自呼吸道标本占63.4%，其他标本各占5%左右；细菌检出占构成比前三位的依次为铜绿假单胞菌19.5%、肺炎克雷伯菌16.7%、大肠埃希菌14.3%；耐甲氧西林金黄色葡萄球菌、耐甲氧西林凝固酶阴性葡萄球菌和耐万古霉素的肠球菌的发生率分别为88.2%、70.0%和11.1%；大肠埃希菌和肺炎克雷伯菌的超广谱β-内酰胺酶的检出率分别为68.6%和65.2%，铜绿假单胞菌对亚胺培南的耐药率为40.2%；白色念珠菌对氟康唑的耐药率为81.3％，对两性霉素的耐药率为3.2%。

Because this threshold is set from the four MSBs, the user can quickly adjust the system gain to avoid an overrange condition.

由于此阈值由四个最高有效位设置，因此用户可以迅速调整系统增益，以避免发生超量程情况。

For example, the fast detect feature allows fast overrange detection by outputting four bits of input level information with very short latency.

例如，快速检测特性可以通过输出四位输入电平信息实现快速检测超量程输入，并且延迟极短。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
