Objective:To investigate the quantitative expression of Melanoma-associated antigen MAGE-E1 mRNA in glioma, and explore its potential for immunotherapy in glioma.Methods:To establish a quantitative real-time polymerase chain reaction ( qRT-PCR) method to quantitatively determine MAGE-E1 mRNA in glioma.A total of 47 human glioma and 14 normal brain tissue specimens were analyzed.MAGE-E1 mRNA was normalized to HPRT1, a housekeeping gene.MAGE-E1/HPRT1 was used to evaluate the expression level of MAGE-E1 mRNA.Results:High-level expression of MAGE-E1 was observed in 7.1%of normal brain and 66.0%glioma tissues,which shown significant difference with P<0.05.There was irrelevant between the expression of MAGE-E1 mRNA and clinicopathogical parameters ,such as gender ,age,histological subtype and grade.Conclusion:With higher expression of MAGE-E1 in glioma tissues,it might be a potential target for immunotherapy of glioma.

AIM: To evaluate the effects of NS-398, a cyclooxygenase-2(COX-2) inhibitor, on the proliferation and apoptosis in HepG2 cells. METHODS: The effects of NS-398 on the proliferation of HepG2 cells was evaluated by MTT. DNA fragmentation gel analysis was used to analyze the apoptotic cells; DNA ploidy and apoptotic cell percentage were examined by flow cytometry. Furthermore, the expression of COX-2 and Bcl-2 mRNA was identified by competitive RT-PCR. RESULTS: NS-398 inhibited cell proliferation and induced apoptosis in HepG2 in a concentration-dependent manner. DNA ploidy analysis showed that S phase cells were significantly decreased with NS-398 concentration increasing. The quiescent G_0/G_1 phase was accumulated with decreasing of Bcl-2 mRNA. Whereas NS-398 had no effect on the expression of COX-2 mRNA, no correlations were found between COX-2 mRNA and the HepG2 cell proliferation and apoptosis induced by NS-398 (r=0.056 and r=0.119, respectively). CONCLUSION: NS-398 significantly inhibits the proliferation and induces apoptosis in HepG2. Mechanisms may be involved in accumulation of quiescent G_0/G_1 phase and decrease in Bcl-2 mRNA expression, but independent to COX-2 mRNA expression. [

OBJECTIVETo study clinical effects of a new internal fixation by using a cable through the bone and Kirschner with a hole in the tail, for the treatment of patellar fractures.

METHODSFrom May 2012 to July 2013, thirty-four patients with patellar fractures were treated with cable through the bone and Kirschner with a hole in the tail. All the patients had close fracture,including 12 transverse fractures and 22 comminuted fractures. There were 18 males and 16 females, ranging in age from 26 to 81 years old, with an average of (46.0 ± 3.0) years old. After open reduction, two appropriate length of Kirschner with a hole in the tail were driven into the patella as perpendicular to the fracture line or the major fragments as possible. A transverse bone tunnel was then drilled with a Kirschner at one side of the patella. Then the cable, which was successively pulled through the bone tunnel and the hole of Kirschner, was crossed in a figure-eight over the anterior of the patella, tightened and fixated by special instruments. The Kirschner was clipped off on the edge of the hole. If it was a comminuted fracture, another cable was used to fasten the patella with cerclage. Postoperative evaluation was based on Bostman.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 26 months, with a mean of (16.0 ± 2.0) months. Fractures healed in all the cases without such complications as infection, loosening of Kirschner and cable loop, and skin irritation. According to the Böstman score system, 33 cases got an excellent result, and 1 good.

CONCLUSIONThe cable through the bone and Kirschner with a hole in the tail is a simple, stable and effective method for the treatment of patellar fractures, especially the transverse fractures, with earlier knee exercise and fewer complications.

Background and purpose: Three-incision esophagectomy for patients with esophageal cancer has been increasingly used, but the incidence of either postoperative anastomotic leak or stricture is higher than that in intrathoracic gastroesophageal anastomosis. The purpose of this study was to investigate the clinical effects of the side-to-side stapled cervical gastroesophageal anastomosis in preventing anastomotic leak and stricture after three-incision esophagectomy. Methods: One hundred and twenty-seven patients undergoing three-incision esophagectomy for esophageal cancer with gastric replacement were reviewed. A side-to-side stapled cervical gastroesophageal anastomosis was performed in 71 cases and manually sewn anastomosis in 56 cases. The incidence of postoperative anastomotic leak and stricture was compared between these two groups and the results were statistically analyzed using SPSS11.0 soft.Results: Anastomotic leakage was noted in seven patients (9.9%) in the stapler group and fourteen patients (25.0%) in the manually sewn group (P=0.04). After the operation two patients (2.8%) in the stapler group and nine patients (16.1%) in the manually sewn group developed a benign esophageal stricture (P=0.02).The incidence of either postoperative anastomotic leak or stricture in cases of the stapler group was significantly lower than that in the manually sewn group (P<0.05). Conclusion: Construction of the cervical esophagogastric anastomosis with a side-to-side stapled technique provides a larger luminal diameter which significantly reduces the incidence of postoperative anastomotic strictures. The surgery also greatly reduces the incidence of anastomotic leaks and strictures, so it could be used as an alternative strategy for cervical esophagogastric anastomosis after esophagectomy for esophageal cancer

Objective To explore the reproducibility of normal hepatic MRS at 3.0T. Methods The hepatic proton MRS was performed with GE Signa Excite HD 3.0T system and eight-channel torso phased-array coils using PRESS sequence. Thirty-one healthy individuals were enrolled in this study. Liver spectra were collected with TR of 1500 ms, TE of 30 ms, ROI of 2 cm×2 cm×2 cm, NSA of 64 times. The outcomes were statistically analyzed with Wilcoxon signed ranks test and Spearman correlation test.Results There was no significant difference of signal to noise ratio (Z=-0.535,P=0.593), baseline stability (Z=-0.333, P=0.739), linewidth of automatic shimming (Z=-0.305, P=0.761), water suppression (Z=-1.232, P=0.218), height of lipid peak (Z=-0.558,P=0.557), area under the lipid peak (Z=-1.195,P=0.232), height of water peak (Z=-0.647,P=0.518) and area under the warter peak (Z=-0.118, P=0.906) between first examination and second examination. Correlation coefficient of the former and the later measurements of lipid area and water area were 0.784 (P<0.001) and 0.799 (P<0.001), respectively.Conclusion The reproducibility is good for in vivo liver proton MRS at 3.0T.
