ConclusionThe expression of α-B crystallin in IDC is significantly higher than that in DCIS and is positively related to lymph node metastasis. There are also higher levels of expression in the HER2+ and the triple-negative groups. This suggests that α-B crystallin is involved in the process of progression and metastasis of breast cancer.

结论α-B crystallin在乳腺浸润性导管癌中的表达明显高于导管原位癌，与淋巴结转移呈正相关，且在生物学行为更为恶性的HER2+组和三阴性组具有更高的表达水平，提示α-B crystallin蛋白可能参与了乳腺癌的浸润与转移过程。

In addition, the human X-specific and Y-specific whole chromosome painting probes were hybridized onto metaphase spreads obtained from male of Elaphodus cephalophus.No signals were detected, which indicates the phylogenetic relationship between human and the tufted deer is not close.

分别用人X、Y染色体特异的整条染色体涂染探针，通过荧光原位杂交的方法，检测核型Ⅰ中是否存在与人X、Y染色体同源的片段，结果显示该毛冠鹿间期、中期细胞都呈阴性，提示可能毛冠鹿与人的亲缘关系较远。

In both HLA-B27 positive and negative groups, positive rate for HLA-B13/B40 was higher than that of HLA-B7/B40, implying that the heterozygotic frequency of B13 and B40 loci as well as the cross-reactivity of their antigens or both was higher.

无论在HLA-B27阳性还是阴性人群中，HLA-B13/B40的抗原阳性率远高于HLA-B7/B40的阳性率，说明B13和B40位点的杂合或交叉，远大于B7与B40之间的杂合或交叉。

It results from theformation of infusible salt or hydrates by the complexing reaction of metal ion andnegative ions in alkaline solution. The stability mechanism was discussed byemploying scanning electronic microscope and x ray photoelectronspectroscopy.

结果表明，在中性介质中，其稳定性较好，而在碱性介质中的稳定性较差，这是因为在碱性介质中金属离子与介质中的阴性离子络合形成难溶性的盐或氢氧化物，加速了GIC的分解所致。

"Carotid ultrasound appears to offer incremental value to EST in predicting presence or absence of ≥50% coronary diameter stenosis in symptomatic patients with equivocal/negative EST result," Kanwar and co-authors conclude.

Kanwar 和他的同事得出结论：在运动负荷试验结果阴性或可疑的有症状的病人中，颈动脉超声增加了运动负荷试验预测是否存在≥50%冠脉狭窄的价值。

The results were expressed in mean±1SD. Pearson X~2 test and One-way ANOVA test were used. The data analyzed using the SPSS (version 11.5). Results: The sensitivity, specificity, positive and negative value of US for the LPEH model on the children cadaver were 88%, 84%, 79%, 91%, respectively. With regard to the thickness of femora head cartilage, the thickness of the anterior layer or posterior layer, there were no significant differences among three groups. However, the anterior layer was thicker than the posterior layer in three groups. The fluid in hip joint was detected in all of 21 symptomatic hips, which was clear commonly (90%) in early procedure. The amount of fluid in anterior recess showed a positive correlation with age (p .05). No fluid was detected in the asymptomatic and normal hips (2mm). The mean maximum width of inferomedial recess was significantly larger than that of anterior recess (12.50±4.04mm vs.4.35±0.8mm, p 0.05) in the symptomatic hip joints. The echogenic entrapped labral plicaes were demonstrated in the inferomedial recess in all of 21 children with LPEH, whose length and width ranged from 5.3mm-25.0mm (mean,15.6±5.6mm) and from 4.0mm-17.0mm (mean,8.9±7.8mm).

结果1，尸体LPEH髋关节模型的超声诊断敏感性、特异性分别为88％、84％，阳性预测值、阴性预测值分别为79％、91％。2，21例患儿的LPEH患髋(21侧)、健髋(21侧)，以及21例正常儿童健髋(42侧)的超声检查显示：髋关节周围软组织及股骨头无形态结构差别；股骨头软骨厚度无统计学差异(3.5±0.5mm vs.3.6±0.4mm vs.3.6±0.5mm，p＞0.05)；关节囊前层及后层厚度无统计学差异(前层厚度2.79±0.74 mm vs.2.56±0.40mm vs.2.56±0.72mm；后层厚度2.70±0.82mm vs.2.48±0.54mm vs.2.44±0.58mm，p＞0.05)，但LPEH患髋关节囊前、后层均较后二组有增厚趋势。3，LPEH患髋均存在关节腔内积液，且早期较为清晰；积液以髋关节内下间隙明显，内下间隙较前间隙明显增宽(12.50±4.04mm vs.4.35±0.8mm，p＜0.05)，其内见嵌顿滑膜唇皱襞呈稍强回声的占位性团块，长约15.6±5.6mm，宽约8.9±7.8mm，90.5％(19／21)嵌顿皱襞内未见血流信号。4，所有LPEH患髋治疗后超声复诊均显示正常。

The central theme of this thesis is to investigate the expression of lymphocyte surface marker and concentration of serum cytokines in four groups of patients with sepsis : Group 1, patients with Gram positive bacterial infection; Group 2, patients with Gram negative bacterial infection; Group 3, patients with negative cultures but strong evidence of infection; Group 4, patients without clinical and microbiologic evidence of infection as control group.

本研究主要以临床诊断为主再配合血液培养将病人分为四组：第一组是有革兰氏阳性细菌感染的病人；第二组是有革兰氏阴性细菌感染的病人；第三组是没有培养出细菌的感染性病人；第四组是由临床诊断及微生物培养证实为正常对照组。利用单株抗体接上萤光物质再配合流式细胞分析仪来测定淋巴球上各种细胞膜表面分化抗原的变化及利用酵素免疫分析法来探讨血清各种细胞素之变化。

BFGF immunoreaction was detected at 3-weeks' embryonic neuroepithelium, and remained positive throughout various development a l stages examined, whereas NGF immunoreaction appeared after 4-weeks. The expres sion varied gradually with the development of embryos. There was no specific EGF immunoreaction in all tissues and stages examined. The occurrence and distribut ion of FGFR, NGFR and EGFR were similar, and their expression altered with the development.

结果显示bFGF和NGF的表达时序不同，b FGF阳性细胞出现较早，在所检测的各个发育阶段均呈阳性表达，而NGF出现较晚，随着胚龄增加，免疫阳性着色逐渐增强，bFGF分布较NGF广泛，而EGF在所检测的各个发育阶段均呈阴性。flg、TrkA、EGFR表达时序和分布相似，三者在所检测的各个发育阶段均呈阳性。
