Theurinary IL-6 level positively correlated with density of glomerular matrix membrane, global sclerosis, fiber or fibrocellular crescents and interstitial fibrosis (p. 05). According to the degree of density of glomerular matrix membrane and interstitial fibrosis, urinary Col-IV level had better correlation than urinary TGF-betal and IL-6 levels.In IgAN, Col-IV showed increased expression in diseased renal tissue whereas the site of expression of TGF-betal was mainly localized within the cytoplasm of tubular epithelial cells. Interstial expressionwas also present but glomerular TGF-betal expression was found only in patients with heavy mesangial proliferation. There was a significant correlation between glomerular positivity for Col-IV and severity of histological damage. There was also a significant correlation between positivity for TGF-betal and Col-IV in the tubular epithelial and interstitial lesions. In contrast, there was no ralationship between glomerular positivity for TGF-betal and severity of histological damage.The urinary TGF-betal level paralleled tubular TGF-betal expression.

结果 ①IgAN患者尿TGF-β1、IL-6、Col-Ⅳ水平较健康人明显增高(P＜0.01)，该变化与血中的浓度无关(P＞0.05)；②尿TGF-β1水平与小管间质TGF-β1阳性表达呈正相关(P=0.000)，而与小球TGF-β1阳性表达无关(P＞0.05)，尿Col-Ⅳ水平与小球和小管间质Col-Ⅳ阳性表达均呈良好的相关性(P＜0.01)，还与小管间质TGF-β1阳性表达呈正相关(P＜0.05)：③小球Col-Ⅳ阳性表达与肾组织慢性病变密切相关(P＜0.05)，小管间质Col-Ⅳ和TGF-β1阳性表达均与肾小管间质病变呈良好的相关性(P＜0.01)，而小球TGF-β1阳性表达与肾组织损伤无关(P＞0.05)；④尿TGF-β1、Col-Ⅳ水平与肾小球基质基底膜面密度、小管间质病变呈正相关(P＜0.01)，与小球内细胞数呈负相关(P＜0.05)，该结果与其在组织中的表达一致；尿IL-6水平浙江大学硕士学位论文尿TGF一B一、IL一6和Col一IV在IgA肾病中的应用价值与基质基底膜面密度、球性硬化、纤维或细胞纤维新月体所占肾小球百分数及小管间质病变均有显著的相关性(F.05)；在轻度肾病理损伤时，尿'l'G卜pl、I卜6、Col一IV水平即升高，而尿Col一W在反映细胞外基质积聚和间质纤维化程度上比尿TGF一pl和IL一6有更好的相关性。

First described in 1955, nodular fasciitis, or pseudo sarcomatous fibromatosis, is a benign, self-limiting reactie process composed of proliferating fibroblasts in a myxoid stroma.

序论结节性筋膜炎，或称假肉瘤样纤维瘤病于1955年首次提出，是良性的自限性反应性病变，其粘液间质由增生的成纤维细胞组成。

Moreover, no significant changes in flagellar mobility, biofilm formation and production of extracellular cellulase and xylanase in vitro were observed in △rbfCxoo compared to PXO99A. Most importantly, the deletion mutation of rbfCxoo resulted in enhanced virulence and gene expression.

此外，△rbfCxoo鞭毛运动性、生物膜形成和胞外纤维素酶和木聚糖酶活性都无明显改变，但对水稻的致病性显著增强，毒性相关基因的表达也有所增加。

Non-occluding teeth with a hypofunctional periodontium have a lower rate of bone remodeling, and are more susceptible to the injury in periodontal tissues caused by orthodontic force than normally occluding teeth, such as hyalinization or undermining bone resorption, even dentin resorption.

正畸治疗中，无咬合接触的牙周膜废用性萎缩牙较正常咬合接触牙对矫治力反应差，骨改建率低，易发生玻璃样变和潜掘性骨吸收，延缓牙移动，因此对无咬合接触牙的临床治疗中应采用轻力。

试验结果表明：经过盐雾腐蚀的涂层表面的均匀性和完整性均被破坏，涂层表面产生了大量的腐蚀坑；高温循环氧化以后，表面形成的Al2 O3 氧化膜变得粗糙、破碎且不连续，而且氧化膜容易剥落，降低了涂层的高温抗氧化能力，缩短了涂层的使用寿命

Isolated rotatory dislocation is very rare in adults.11–13 Few cases of AARFs have been reported in adults, perhaps because the cause may often be a severe trauma associated with lethal injuries.3,4,12,14 –19 The mechanisms underlying persistent displacement in traumatic AARF include infolding of the synovial folds into the C1–C2 joints, muscle spasm, subsequent ligamentous contracture, articular cartilage damage, or facet fracture.1,11
