阴性的

In this study, radiolucent calculus accounted for 26.7%of cases, which was much higher than 10%reported in the literature.

阴性结石占本组病例的26.7%(45/168)，超过以往文献报告的10%。

Objective: To investigate the X-ray findings of radiolucent ureteral calculus on IVU, and to evaluate these findings for making diagnosis when coupled with CT.

目的： 通过51例KUB、IVU与CT平扫的对照研究，探讨IVU有关输尿管阴性结石X线表现与CT相结合对输尿管结石的诊断价值。

It may leave something recrudescence and metastasis of breast cancer if adopt correlative measure to depress blood lipids and BMI.

随访巩固期受体双阴性患者，发现血脂、BMI与乳腺癌预后存在相关，通过降低血脂及BMI的相关措施，有可能延缓乳腺癌的复发转移。

WhenPAI-1 level is lower than u-PA level,the tumor cannot protect itself againstthe excess proteolysis of u-PA.Furthermore,high PAI-1 may be associatedwith migration and reimplantation of cancer cells.This hypothesis is supportedby the following observation.

同时基于上述原因，u-PA和PAI-1高表达者，发生周围淋巴结转移的阳性率高于u-PA和PAI-1低表达者。u-PA、PAI-1阳性表达与肝门胆管癌的预后相关，u-PA及PAI-1呈阳性表达者，其生存期较阴性及弱阳性表达者明显减低。

Rickettsia rickettsii is an obligate intracellular gram-negative bacterium, the etiologic agent of Rocky Mountain spotted fever. Human beings are susceptible to the pathogen.

立氏立克次体是落基山斑点热(Roeky Mountain Spotted Fever，RMSF)的病原体，为专性细胞内寄生的小革兰氏阴性菌，人对其十分易感。

The assay is based on TaqMan 3-minor groove binder chemistry using the outer membrane protein B gene as the target. The assay amplified R. rickettsii but other members of the genus rickettsia did not produce positive reactions, nor did other members of the order rickettsiales or any non-rickettsial bacterium.

建立的定量标准曲线Ct值与模板拷贝数呈良好线性关系，最低检测浓度为5拷贝/μl，与普通PCR相比较，敏感性是普通PCR的100倍；用该方法检测其它相关立克次体和常见非立克次体病原菌，检出结果均为阴性。

Pelvic adhesion salpingitis and endometriosis were the major cause of female infertility.Conclusions:Laparoscopic technique can find out the reason of infertility more earlier and more directly and provide timely therapy.So it has excellent clinical effect.

应用腹腔镜技术能早期、直观、准确的明确不孕症输卵管及盆、腹腔病因并可同时予以针对性治疗，在直视下通液，动态观察输卵管通畅度和形态，大大降低了常规通液术的假阳性、假阴性率。

This study was to investigate the possibility of using troglitazone, one of TZD, as the sensitizer of epirubicin in the treatment of estrogen receptornegative breast cancer.

本研究探讨TZD类药物曲格列酮的使用与雌激素受体（estrogen receptor，ER）阴性乳腺癌细胞对表阿霉素化疗敏感性的关系。

All aforementioned cases entierely were proved pathological diagnosis using operation or lung centesis. Results: On the CT manifestation, lobulation sign and spiculation sign mostly appeared in the malignant nodules. The accurate rate of diagnosis was 75.6; sensitivity were 76.3%; specificity were 74.1%; positive predictive value were 86.5%; negative predictive value were 58.8%.

结果：86例SPN的Cr征象中，分叶征和棘突或毛刺征多出现于恶性结节，与病理和随访结果对比，螺旋CT薄层扫描并MPVR重建判断肺小结节良恶性的准确率、灵敏度、特异性、阳性预测值和阴性预测值分别为75.6%、76.3%、74.1%、86.5%、58.8%。

The possible inuence of mainly immunological risk factors early after transplantation leads to manifestation of CAN in a shorter period. 4. The study showed no impact of C4d expression on mean serum creatinine levels at the time of biopsy and during 1-year observation. More patients with peritubular C4d deposition lost their grafts during the study period. 5. Deficiency syndrome-type with CAN usually are spleen-kidney Qi deficiency and hepatic and renal Yin deficiency; Sthenia syndrome with CAN usually are syndrome of blood stasis and damp-heat syndrome

并且发生CAN时间早于阴性组；体液免疫因素在慢性移植物肾病早期可能是一个重要危险因素；4、两组的肌酐水平在穿刺时及穿刺后1、3、6、12月没有统计学意义，但C4d阳性组穿刺后1年内失功率高且预后差；5、慢性移植物肾病患者的中医证型特点是本虚标实；本虚主要是脾肾气虚、肝肾阴虚，标实主要是血瘀、湿热。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
