闭合复位治疗婴幼儿发育性髋脱位的疗效观察

Objectives To retrospectively review the results of closed reduction for developmental dysplasia of the hip (DDH), and analyze the causative for the dissatisfactory results of radiolagieal. Methods From 1997 to 2005 the results of closed reduction for DDH in 60 children (77 hips) over 4.5 years period were retrospectively reviewed. Radiological final results of the patients were evaluated with Severin classification. The causative factors made from medical records and radiographs were used to make statistical analysis. Results Seventy-three percent of the patients (56/77) had satisfactory results according to Severin classification. Twenty-one hips classed as SeverinⅢ-Ⅴ. Seventeen of the 21 hips had a reconstructive procedure. Avaseular necrosis was observed in 29 hips (38%). The most important parameters affecting the result were age at reduction (P ＜ 0. 05) and avascular necrosis (P ＜ 0.05).Conclusions In order to achieve better clinical and radioiogical results, the infants suffering from the DDH should be treated in the early stage. The postoperative avascular necrosis usually leads to poor prohnosis.

Flow-induced Expression and Phosphorylation of VASPin Endothelial Cells

1 Introduction It is well known that mechanical forces have important influence on endothelial cells, in particular, on cytoskeleton reorganization. VASP (vasodilator stimulated phosphoprotein) is a 46 KD actin associated protein. It is a member of Ena/VASP protein family and composed of EVH1, proline-rich and EVH2 domains. It is considered as an important component of the sub-cellular regions where remodelling of the actin cytoskeleton takes place, such as the front of spreading lamell…     

人大肠癌中基质金属蛋白酶-7 mRNA的表达

目的:探讨基质金属蛋白酶-7(matrix metalloproteinase 7,MMP-7)与大肠癌浸润和转移的关系.方法:用逆转录聚合酶链式反应(RT-PCR)检测大肠癌和正常黏膜、炎性息肉、腺瘤及淋巴结中MMP-7 mRNA的表达.结果:97.4%(37/38)的大肠癌和1例肝转移中MMP-7 mRNA表达阳性,而相应正常黏膜几乎不表达;大肠癌中MMP-7 mRNA的表达水平随Dukes分期的进展而逐渐升高(P＜0.01),A期(0.28±0.08),B期(0.54±0.17),C期(0.55±0.09),D期(0.73±0.06).5例腺瘤MMP-7均为阳性,但表达水平低于癌组织(P＜0.01);3例炎性息肉均未见MMP-7表达.传统组织学检查有癌转移的13个淋巴结MMP-7表达均为阳性;组织学检查未见转移的12个淋巴结MMP-7表达6个阴性、6个阳性,再次行组织学检查于6个MMP-7阳性者中发现3个有微转移.结论:MMP-7的高表达可能在大肠癌的浸润和转移过程中具有重要作用;用RT-PCR方法检测淋巴结中MMP-7mRNA的表达是诊断大肠癌淋巴结微转移的敏感方法.     

Chronic neuroprotective effects of low concentration lithium on SH-SY5Y cells:possible involvement of stress proteins and gene expression

To investigate the molecular mechanism underlying the neuroprotective effect of lithium on cells, in this study, we exposed SH-SY5Y cells to 0.5 mmol/L lithium carbonate(Li2CO2) for 25–50 weeks and then detected the expression levels of some neurobiology related genes and post-translational modifications of stress proteins in SH-SY5Y cells. cDNA arrays showed that pyruvate kinase 2(PKM2) and calmodulin 3(CaM 3) expression levels were significantly down-regulated, phosphatase protein PP2A expression was lightly down-regulated, and casein kinase II(CK2), threonine/tyrosine phosphatase 7(PYST2), and dopamine beta-hydroxylase(DBH) expression levels were significantly up-regulated. Besides, western blot analysis of stress proteins(HSP27, HSP70, GRP78 and GRP94) showed an over-expression of two proteins: a 105 kDa protein which is a hyper-phosphorylated isoform of GRP94, and a 108 kDa protein which is a phosphorylated tetramer of HSP27. These results suggest that the neuroprotective effects of lithium are likely related to gene expressions and post-translational modifications of proteins cited above.
