阴性

Among them, TLR2 and TLR4 recognize lipopolysaccharide and lipoproteins, respectively. TLR9, which is restricted to antigen presenting cells , is specific for unmethylated CpG oligodeoxynucleotides that are present in bacterial DNA.

其中TLR2和TLR4分别参与革兰氏阳性细菌肽聚糖和革兰氏阴性细菌脂多糖的识别，TLR9主要存在于抗原递呈细胞表面，特异识别存在于细菌基因组中的CpG motif。

Molecular analysis and disease-resistance test The regenerated kanamycin resistant plants were analyzed by PCR andPCR-Southern reaction with the untransformed plants as negative control, plasmidDNA as positive control.

转基因植株分子检测及抗病性鉴定以未转化植株为阴性对照，质粒DNA为阳性对照，nptⅡ基因和chit42基因的特异引物进行PCR和PCR-Southern检测。

Abstract］ Objective To diagnose negative ureterolith with 3D reconstruction of multi-slice helical CT.

目的 应用多层螺旋CT的三维重建诊断阴性输尿管结石。

Results 19 of 20 cases displayed negative ureterolith throuth miltis-lice helical CT with MIP and SSD of 3D.1 case was only uretero-narrow withoutstone.

结果 20例输尿管阴性结石患者CT扫描，并用最密度投影和表面遮盖法重建，19例满意显示输尿管结石，1例输尿管下端炎症狭窄，未显示结石。

The positive rate of escherichia coli was the highest followed by co-agulase negative staphylococci,klebsiella pneumoniae and blue verditer pseudomonas.

阳性率最高的是大肠埃希菌，其次是凝固酶阴性葡萄球菌、克雷伯菌、铜绿假单胞菌。

Concl us ion:The main factors that induce severe infection in bronchiectasis were the lowered immune function in the patients and the infection of Gram-negative bacteria,especially blue verditer pseudomonas.

结果：患者免疫功能低下和革兰氏阴性杆菌特别是铜绿假单孢杆菌感染是引起支扩感染加重住院的主要因素。

When a liver or kidney or both are found violative but the skeletal muscle is negative or non-violative, then only the organs shall be condemned.

当肝脏或肾脏或二者都不合格，但骨骼肌呈阴性或没有违规，那么应该只宣布器官不适于食用。

The prevalence of antibodies against HCV in hepatitis B surface antigen-negative patients is around 70-80%, and most of them are viremic.

C型肝炎病毒感染是本地慢性肝病的第二大原因，B肝表面抗原阴性的慢性肝炎息者中，70~80%为C肝抗体阳性，且多数体内存有病毒。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
