BACKGROUND:The elastic modulus of the fiber post is close to that of the dentine, so they can form a homogeneous whole and share the masticatory force, which can ease the stress concentration of dentine and prevent from tooth fracture. OBJECTIVE:To observe clinical effects of anterior teeth with flared root canals restored by fiber posts using three application methods. METHODS:Anterior teeth with flared root canals from 48 patients were involved. They were divided into three groups, then restored with three post-core crowns respectively: a single fiber post, rehabilitation with composite resin, and fiber post combined with accessory post. Al patients were folowed up for 2 years to observe post and core loosening, fracture and root fracture. RESULTS AND CONCLUSION:The group of a single fiber post was failed in eight teeth including four cases of post and core loosening and four cases of post and core fracture, with a successful rate of 64%. The group of rehabilitation with composite resin was failed in three teeth including two cases of post and core loosening and one case of post and core fracture, with a successful rate of 90%. The group of fiber post combined with accessory post was failed in two teeth of post and core loosening, with a successful rate of 93%. The successful rate of the group of a single fiber post was lower than that of the groups of rehabilitation with composite resin and fiber post combined with accessory post (P < 0.05) . The difference between the groups of rehabilitation with composite resin and fiber post combined with accessory post was not statisticaly significant (P > 0.05). The clinical effects of rehabilitation with composite resin and fiber post combined with accessory post are better than that of a single fiber post. But the method of combination fiber post with accessory post is recommended because of easy operation.

Objective To evaluate the clinical effects of endovascular angioplasty and stenting for the treatment of TASC B,C arteriosclerotic occlusion(ASO) of lower extremity.Methods After the identification of the occlusion by angiography via femoral artery access by Seldinger method,the occluded arteries (mean length 7.5cm; range 1~20 cm) in 40 patients(47limbs) were treated by percutaneous transluminal angioplasty and stent placement. Results The primary recanalization was successful in 45 of 47 limbs. The technical successful rate was 96%. Thirty one self-expanding stents were deployed. PTA without stent placememt was performed in 16 limbs(of them,11 were blow knee).The ankle brachial pressure index (ABI) increased from (0.36?0.14) preoperatively to (0.82?0.15) on the 7th postoperative day. All patients were follow-uped for 1 to 48 months. Stents were occluded in 4 patients. Restenosis was observed in 1 limbs. All of the rest remained patent in the follow-up period.Conclusion Endovascular angioplasty and stenting can be an effective method for the treatment of long segmental (including below-knee) arteriosclerotic occlusion of lower extremities.

Objective To investigate the expression level of LMO1 in gastric cancer tissues and human gastric cancer cell lines,and explore the invasive and metastatic potential of LMO1 gene silencing by small interfering RNA on the human gastric cancer cell line MKN28.Methods Immunohistochemical technique was applied to detect the expression of LOM1 protein in gastric cancer tissues and tumor adjacent tissues of paraffin specimens in 30 cases.The expression levels of LMO1 in human gastric cancer cell lines AGS,BGC-823,SGC-7901,MKN28 and human gastric mucosal epithelial cells GES were detected by realtime-PCR and Western blot.Using LipofectamineTM 2000,LMO1 siRNA was transfected into MKN28 cellsin vitro (siRNA transfect group).Negative control was established.Real time-PCR and Western blot was used to examine the difference of LMO1 expression.Transwell assays were performed to identify the differences and changes of invasive and metastatic ability in gastric cancer cell line MKN28.Western blot was used to examine the expression levels of E-cadherin,MMP-9 and VEGF.Results Positive rate of LOM1 protein in gastric cancer tissues(77％)was higher than that in tumor adjacent tissues (17％) (x2 =21.70,P ＜ 0.01).Positive rate of Vavl protein was higher in lymphatic metastasis group than in non-lymphatic metastasis group(x2 =5.83,P =0.02).Compared with GES,the expression level of LMO1 increased significantly in gastric cancer cell lines,especially in MKN28 (P ＜ 0.01).The expression levels of LMO1 mRNA and protein in LMO1-siRNA transfected MKN28 cells were lower than the matched negative control cells (P ＜0.01).The invasive and metastatic potentials of LMO1-siRNA transfected MKN28 cellssignificantly decreased (t =-11.53,P ＜0.01;t =-10.68,P ＜0.01).The expression levels of E-cadherin were higher than the matched negative control cells;and MMP-9,VEGF protein in LMO1-siRNA transfected MKN28 cells were lower than the matched negative control cells (P ＜ 0.01).Conclusions LMO1 has higher expression level in gastric cancer tissues and some gastric cancer cell lines,and down-regulation of LMO1 can inhibit the invasion and metastasis ability of gastric cancer.
