And it was divided into four groups at randomly (n=6),The vertical compression,bending and torsion intensity in without and with reduction of cortical fragment of plate fixated contra side, without and with reduction of cortical fragment of plate fixated sidewere measured.A11 results were analyzed with statistic method.2、animal experiment :The 12 adult goats were divided into two group at randomly,wedged cortical defect with 1 cm of long and conjugate diameter was created in the middle-part of the medial femur and plate was fixed in the defect side and as the experimental side,the other side was control.after operation 4、8、12 weeks,investigation of the fracture healing by means of gross observation,X-ray examination and histology in both sides.

测试各组的垂直压缩、三点弯曲及抗扭转的刚度。2、动物实验：12只健康成年山羊，雌雄不限，体重在20～25kg之间，在同一只羊双侧股骨中段内侧制造楔形骨皮质缺损，分实验组和对照组两组进行钢板内固定并植骨，于术后4、8、12周对实验组及对照组行X线正位片检查，观察骨折愈合过程中不同时间点的影像学特点。于4、8、12周各组处死4只动物行大体标本观察，并取缺损区骨组织行组织学检查。X线检查及组织学检查结果根据LaneX线评分标准及组织学评分标准进行评分。最后采用SPSS13.0进行统计学分析。

The inhibin a gene、 the bone morphogenetic protein 4 (BMP4) gene and the bone morphogenetic protein 7 (BMP7) gene were studied as candidate genes on the prolificacy of Small Tail Han sheep. Single nucleotide polymorphisms of 5 ' regulatory region、 exon 1 of INHA gene;exon 2、 exon 3 and exon 4 of BMP4 gene and exon 2、 exon 3 of BMP7 were detected in high fecundity breed and low fecundity breeds (Chinese Merino sheep, Corriedale sheep and South African Mutton Merino sheep) by PCR-SSCP. The results indicated that there was a mutation (316C→T) in 5' region of INHA gene in Small Tail Han sheep, Chinese Merino sheep and Corriedale sheep, the same mutation did not exist in South African Mutton Merino sheep.

采用PCR-SSCP技术检测抑制素α(inhibin α，INHA)基因5'调控区、外显子1，骨形态发生蛋白4(bone morphogenetic protein 4，BMP4)基因外显子2、外显子3和外显子4以及骨形态发生蛋白7(bone morphogenetic protein 7，BMP7)基因外显子2和外显子3在高繁殖力绵羊品种以及低繁殖力绵羊品种(中国美利奴绵羊、考力代绵羊、南非肉用美利奴绵羊)中的单核苷酸多态性，同时研究这三个基因对小尾寒羊高繁殖力的影响。

Results］ In the 80 cases of GCS score 8 to 12, 28 of them were in craniotomy group; 27 were in SBWP group and 25 were in SCAH group.

结果］GCS 8～12 分80例中：骨瓣组28 例，小骨窗组27 例，血肿碎吸组25 例。

The denaturation of the physical chemical and/or biological properties of collagen will lead to the risk of deformation and fracture in bone.
