1、·中文论著摘要·BMP-2在骨性下颌前突的下颌骨组织中的表达研究目的探讨BMP-2蛋白在骨性下颌前突中的下颌骨组织中的表达及临床意义。材料与方法选择35例骨性下颌前突畸形患者正颌手术切除的下颌骨组织以及19例下颌智齿拔除废弃的正常下颌骨组织。用BMP-2多克隆抗体进行SP法免疫组化染色,研究分析BMP一2蛋白在骨性下颌前突及正常下颌骨组织中的表达情况。免疫组化评价标准阳性标准:胞浆中可见棕黄色颗粒状染色。阴性标准:胞浆中无棕黄色颗粒状染色。A(按切片中显色细胞有无及显色深浅来评分),0分为无色,1分为浅黄色,29为棕黄色,3分为棕褐色。B(按切片中显色细胞的个数占切片中细
2、胞总和的百分比来评分),25%以下为1分,25%-75%为2分,75%以上为3分。每例总积分=A粕,按总积分高低分为:O分为阴性(一),1-4分为弱阳性(+),4-6分为阳中性(++),大于6分为强阳性(+++)。利用图像分析系统计数BMP一2染色的平均光密度值,以确定细胞中BMP一2的相对含量。采用SPSSl3.0统计软件包分析数据。下颌前突组和正常下颌骨组中BMP一2的相对含量比较,进行独立样本t检验及卡方检验。结果35例下颌前突的下颌骨组中有30例免疫组化呈阳性。BMP-2蛋白阳性细胞呈现胞浆染色,位于成骨细胞、成软骨细胞、软骨基质中且阳性信号表达较强(++一+++
3、),阳性率为85.7%;19例正常下颌骨组中1l例免疫组化阳性。BMP-2蛋白阳性细胞位于成骨细胞、成软骨细胞、未钙化的骨组织基质及周围的纤维组织,且大部分区域阳性信号表达较弱(+一++),阳性率为57.9%。经四格表卡方检验,两组间阳性率有显著差异,具有统计学意义(P4、;骨发育;骨性下颌前突;免疫组化2英文论著摘要AstudyonexpressionofBMP··2inthetissueofmandiblein'●■'●manOl19ularoroKnathlSmObjectiveToexploretheunusualfeatures,mandibleproteinofBMP一2proteinexpressioninanti-jawboneandclinicalsignificance.MethodsCompleteclinicaldataof35specimens,thecasesdiagnosedasskeletalclassⅢja5、wprotrusiondeformitymandibularbranchsagittalsplitmandibularosteotomysurgery.19casesofnormalmandibleforthenormalcontrolgroup,andcollectinformationsuchasage,gender,location.ByimmunohistochemicalSPmethodtoobservethetestingandthenormalorganizationofBMP·2proteinintheimmunohistochemicalstaining6、intensityanddistributionofcharacteristies.Immunohistochemicalevaluationcriteria:Browngranularstaininginthepositivestandard:thecytoplasmornucleus,orextracellularmatrix..Nobrowngranularstaininginthenegativecriteria:thecytoplasmornucleus,orextracellularmatrix.刀摇imageanalysissystemtocounteach7、groupofcellsofBMP-2EvaluationofdyeinggrayvaluetodeterminetherelativecontentofthecellsofBMP-2.UsingSPSSl3.0softwareforwindowsstatisticalpackagetoanalyzedata.MandibleintherelativecontentofBMP-2single-factoranalysisofvariance.ResultsBMP-2proteinbyimmunohistochemicalsta
