Objective:To develop a Wnt-dependent ?-catenin-mediated functional assay system.Methods:To construct a vector,pCMV-bcGFP,which can express the ?-catenin and green fluorescent protein(GFP) fusion protein;transfect HEK293 with the vector,select the cells with G418 and LiCl and establish the stable cell line,293-bc-GFP by cloning.Results:293-bc-GFP stable cell line was developed;the background expression of ?-catenin-GFP fusion protein was detectable at a very low level in the cell line under fluorescent microscope and via Western blotting analysis;however,the fusion protein was showed to significantly increase in the presence of Wnt1 and lithium.Conclusion:Our results showed that the system is regulated by ?-catenin in a Wnt-responsive fasion.Thus,it can be used as a functional reporter to identify potential upstream factors during tumorigenesis,as well as to screen for the potential anti-cancer agents that specifically inhibit ?-catenin signaling in human tumors.

OBJECTIVE: To evaluate characteristics and security of artificial synthetic material for repairing incisional hernia of abdominal wall. METHODS: Articles about randomized controlled studies which were focus on repairing incisional hernia of abdominal wall were collected from CNKI from 2001 to 2009 with the retrieval words of "repairing materials for hernia,polypropylene patch, and incisional hernia ofabdominal wall". And then, those articles were summed up and analyzed. RESULTS: Among 24 tests, a total of 1 393 patients who had incisional hernia of abdominal wall, abdominal-wall defect, andinguinal hernia were included in the final analysis. Polypropylene patch and polytetrafluoroethylene patch could reconstruct integrity of abdominal wall during repairing large and huge incisional hernia, characterizing by less trauma, simple operation, rapid recovery, and low relapse rate. However, import patches were expensive. Home-made dacron materials for repairing hernia has been compared with import polypropylene patch, and the results indicated that dacron materials had light foreign body sensation and good complaisance after implantation; additionally, there was no significant difference in security and adverse reaction between dacron materials and import patches. CONCLUSION: Artificial synthetic materials characterize by great biocompatibility, strong anti-tensile strength, excellent tolerance to inflexion, optional cutting, beneficial for abdominal-wall defect at differential sizes, no comfortlessness, rapid recovery, low relapse rate, and less complication. Thus, artificial synthetic materials are extensive prospect.

BACKGROUND:Internal fixation is the main treatment of humeral shaft fractures, especial y for cases accompanied several injuries. According to the fracture reduction method and fixation methods, the commonly used repair methods include intramedul ary nail and minimal y invasive plate. How to choose a safe and effective method of internal fixation is a hot issue in the repair of humeral shaft fractures. OBJECTIVE:To explore the clinical effect of different fixations of intramedul ary nail and plate in the treatment of adult humeral shaft fracture. METHODS:A total of 252 patients with humeral shaft fracture recruited from Heze Municipal Hospital from May 2010 to May 2013 were randomly divided into two groups, with 126 cases in each group. Patients in the two groups were treated with intramedul ary nail fixation and plate fixation, respectively. The average operation time, intraoperative blood loss, hospital stays, and healing time of fracture in the two groups were recorded. Al patients were fol owed up for 1 year postoperatively, the incidence of radial nerve injury, infection and non-union was compared. The recovery of shoulder joint and elbow joint of patients was assessed with Neer method and Mayo method, respectively. RESULTS AND CONCLUSION:After treatment, the rate of primary success of internal fixation showed no significant differences between the two groups (χ2=0.399 7, P>0.05). The average operation time, intraoperative blood loss, the healing time of fracture and hospital stays in the intramedul ary nail group were significantly shorter than that in the plate group B, the difference of the results were extremely significant in two groups (t=15.442 5, 21.713 4, 8.217 6, 1.214 8, P<0.01). After 1-year fol ow-up, the incidence of radial nerve injury showed extremely significant differences between the two groups (χ2=8.262 3, P<0.01);the incidence of nonunion in the intramedul ary nail group was significantly lower than that in the plate group, with extremely significant differences (χ2=3.947 2, P<0.05). The overal incidence of complications in intramedul ary nail group was significantly lower than that in the plate group, with extremely significant difference (χ2=11.977 9, P<0.01). Besides, the Neer scores of shoulder joint and the Mayo scores of elbow joint between the two groups had no statistical y significant difference (χ2=0.235 4, 0.273 0, P>0.05). Both intramedul ary nail and plate fixations show good clinical effect in treatment of adult humeral shaft fracture, and each technique has their advantages and disadvantages, we should choose the proper technique according to the patient’s condition.
