Results In normal tongue mucosa and LP,the positive staining of Notch1 was mainly distributed in stratum corneum, partially in stratum granulosum and stratum spinosum, but not in stratum basale, while the positive staining of EGFR was mainly distributed in stratum basale, rarely in stratum spinosum, but not in stratum granulosum and stratum corneum.

结果 在正常舌黏膜和LP中，Notch1阳性表达主要位于角化层，部分颗粒层和棘层细胞也有表达，基底层无表达；而EGFR阳性表达主要位于基底层，棘层少见表达，颗粒层和角化层无表达。

Methods: A 5ml bone marrow was extracted from the lilac of human volunteers. By Percoll fluid and density gradient centrifugation, the MSC was obtained; after the cells filled the bottom of vessel, subcultured them, when they subculture in third generation, redigested them, 500 R/min centrifugate, alter the completed medium to chemical definition medium, examined the form change and prolifration of cells by invert microscope, toluidine blue stain、immunocytochemical stain and RT-PCR to test the type Ⅱ collagen mRNA and proteoglycan.

Objective To observe the ultrastructure of supra interspinous ligament of ankylosing spondilitis,to evaluate the role of fibroblasts in ossification of ligament,and to discuss if disorderly arrangement of collagen and sedimentation of calcium granule in AS are induced by fibroblasts.

目的 观察强直性脊柱炎棘上棘间韧带的超微结构和探讨成纤维细胞在韧带骨化中的作用。找出AS韧带中胶原紊乱排列和钙颗粒沉积是否由成纤维细胞活动引起。

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

结果：CDK4、P16均表达于胆脂瘤上皮的棘细胞层、颗粒层和角质层，阳性率分别为68.6%、88.6%，高于对照组(前者P=0.011，后者P=0.02)。

However,the positively stained area extended to prickle cell layer in defected skin of verruca planae,verruca vulgaris and condylomata acuminita and the staining intensity was markedly stronger than that in normal skin.

TGK在正常人皮肤仅见颗粒层阳性，其它各层染色阴性；在扁平疣、寻常疣、尖锐湿疣和银屑病中，TGK染色从皮损颗粒层向棘细胞层扩散延伸，染色强度明显增强。
