Here we present a case of 21 year-old male who suffered from recurrent swelling in left side of mandible which had received surgery for ossifying fibroma in another hospital when he was 19 years old. Obvious facial asymmetry was noted but no sensory dysfunctions were detected. The lesion showed well-demarcated, multilocular radiolucency but radiopacity centrally. We applied segmental resection via extra-oral approach and reconstructed with anterior iliac crest bone graft. After removal of MMF in six week, the wound healed well and joint function was good without malocclusion. After follow-up of one year, no recurrences were noted.

What was observed under a light microscope included: tumor cells were mulberry and micropapillary shaped or it was of glandule tubular arrangement; there was obvious interspace between cancer nest and neighboring areas; micropapillary was empty of fiber blood vessel axes; immunohistochemical staining showed ema positive location was both at outward surface of glandule duct and at micropapillary like cancer nest.

Results CsA clearly decreased creatinine clearance and increased urinary excretion of N-acetyl-β-D-glucosaminidase in rats as compared with those in the vehicle group. Morphologic changes consisted of vacuolization of tubular cell, expansion of the interstitium and interstitial fibrosis, hyalinization of afferent arterioles. Severity of the injury was related to the dosage of CsA. Striped interstitial fibrosis and arteriolopathy were more severe in the rats treated with CsA and low-salt diet than with CsA and normal diet.

结果 用CsA的大鼠出现尿量增多、内生肌酐清除率下降、尿N-乙酰-β-D-氨基葡萄糖苷酶排泄增多等；病理上表现为不同程度的细胞浊肿、空泡变性及灶性分布的间质纤维化和小动脉病变，随CsA剂量的增加，病变呈加重趋势；结合低钠饮食，CsA慢性肾毒性病变明显加重。

The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.

After the cell growth curves was recorded, RPE cells of the 3-5th passages were utilized. 2、Three different siRNA (siRNAl,siRNA2,siRNA3) targeting against human cx43 gene and one negative control siRNA were designed and transfected into cultured human RPE cells via liposome reagent. The most effective siRNA can be determined by semi-quantitative reverse transcription PCRRT-PCR. 3、To the most effective siRNA, after transfected into human RPEs with different concentration, the cellular proliferate activities were messured by MTT colorimetry ; the percentages of RPE in different cell circle phase was assayed by FCM; the changes of phenotypical properities were observed with SCM; the protein expression of cx43 was studied through immunocytochemistry stain and Weston blot; the communication intercellular was calculated with FRAP; and the ability of recovery was assessed by using an in vitro wound healing model.4、The total proteins of siRNA1 and RPE were seperated by two-dimensional gel electrophoresis and visualized by silver staining. Proteins with significant expression alterations were selected and their peptide mass fingerprints (PMFs were obtained by matrix-assisted laser desorption/ionization time of flying mass spectrometry (MALDI-TOF-MS).The PMFs were used to search NCBInr database by Auto MS-Fit software.
