Objective To observe the behavior of Schwann cell migration and wrapping up of fibres during co-culture of Schwann cells with steroframe of PLA and PLGA fibres. Methods Schwann cells were mixed into 30% ECM gel and co-cultured with PLA non-spinning fibre steroframes and seeded on one ends of PLGA fibres which were treated with collagen,polylysine or ECM. The attachment,growth and migration of Schwann cells were observed under phase contrast microscope and laser scan confocus microscope. Results (1)When Schwann cells were co-cultured with PLA steroframes,most of the Schwann cells kept in the fibre holes and attached on PLA fibres to form B?ngner band likd structures. (2)When co-cultured with PLGA fibers,Schwann cells could attach and migrate on PLGA fibres and the number of Schwann cells were obviously increased when PLGA fibres were treated by ECM. Conclusions (1)ECM gel colud promote Schwann cells attachment,growth and migration on PLA steroframes and PLGA fibers. (2)ECM gel is a good integrating substance for constructing tissue engineering bioartificial nerve.

Objective To evaluate the efficacy and safety of combined intrapleural therapy with bevacizumab and cisplatin in controlling malignant pleural effusion(MPE)caused by non?small cell lung cancer(NSCLC). Methods A total of 63 NSCLC study subjects with MPE were randomly assigned to one of two groups(A and B). Group A(bevacizumab,n=32)received intrapleural bevacizumab(5 mg/kg)with cisplatin(40 mg/m2) therapy once a week for a total of three cycles. Group B(cisplatin,n=31)received intrapleural cisplatin therapy alone with the same dose and cycle. Pleural fluid was collected from both groups prior to and after treatment. The levels of VEGF in the pleural fluid were determined by ELISA. The cura?tive effect and adverse reaction were observed and follow?up was conducted. Results In 63 evaluable study subjects,the curative efficacy in the be?vacizumab group was significantly higher than that found in the cisplatin group(84.3%vs 61.3%,respectively,P<0.05). But the overall survival (OS)of the two groups showed no statistically significant difference(13.0 months vs 12.0 months,P>0.05). After treatment,The VEGF levels in the MPE were significantly decreased in both groups. In the bevacizumab group,the levels of VEGF in the pleural fluid were significantly lower com?pared to those of the cisplatin group after treatment,showing greater efficacy(P<0.05). The VEGF levels of the two groups whose treatment was in?valid had no statistically significant difference(P=0.079). There was no significant difference in gradeⅢ/Ⅳadverse events between the two groups. All procedures were well tolerated by the patients. Conclusion Combined intrapleural therapy with bevacizumab and cisplatin was effective and safe in managing NSCLC?mediated MPE. The patients showed high tolerance to the therapy. For prediction of local treatment efficacy of bevaci?zumab using the VEGF expression levels in MPE,further research was needed.

Objective To investigate the aberrant methylation and expression of growth arrest and DNA-damage-in-ducible 45 gamma (GADD45G) gene in gastric cardia adenocarcinoma (GCA). Methods Bisulfite conversion-methylation specific polymerase chain reaction method (BS-MSP) and immunohistochemistry method were used respectively to detect the methylation status and protein expression of GADD45G in 138 GCA tumor tissues and corresponding normal tissues. Re-sults The methylation status of GADD45G distal promoter (region 1) was not detected in GCA tumor tissues and corre-sponding normal tissues. For GADD45G region 2 and region 3, the BS-MSP results of region 3 were identical to that of re-gion 2. The methylation frequency of proximal promoter and exon 1 in GADD45G island 2 (region 2 and region 3) in GCA tu-mor tissues (49.3%, 68/138) was significantly increased compared to that in corresponding normal tissues (0, P<0.01). The methylation status of this two sites in tumor tissues was associated with TNM stage of tumors (P<0.05). The protein expres-sion of GADD45G in tumor tissues was significantly decreased than that in corresponding normal tissues (P < 0.05),and threre was a significant negative correlation with methylation status of GADD45G proximal promoter and exon 1 (rs=-0.398). Conclusion The decreased expression of GADD45G by hypermethylation of proximal promoter exon 1 of the gene may play an important role in gastric cardia adenocarcinoma.

Background and purpose:RASSF10 acts as a kind of tumor suppressor in various tumor tissues, but researches in cardiac adenocarcinoma has not been reported. This study aimed to detect the methylation status and expression ofRas-association domain family 10 (RASSF10) in gastric cardia adenocarcinoma (GCA), and explore its role in occurrence and development of GCA.Methods:Methylation speciifc polymerase chain reaction (MSP), reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry method were respectively used to detect methylation status, mRNA expression and protein expression ofRASSF10 in 81 GCA tissues and corresponding normal tissues.Results:The promoter methylation frequency ofRASSF10 in GCA tissues (64.20%, 52/81) was signiifcantly higher than that in corresponding normal tissues (20.99%, 17/81,P<0.05), and was closely correlated with TNM stages, differential degree and lymph node metastasis (P<0.05). RASSF10 mRNA expression in GCA tissues (0.57±0.05) was significantly lower than that in corresponding normal tissues (0.78±0.02,P<0.05), and was closely correlated with TNM stages and lymph node metastasis (P<0.05). Protein expression of RASSF10 in GCA tissues (31.10%, 26/81) was signiifcantly lower than that in corresponding normal tissues (71.60%, 58/81,P<0.05), and was closely correlated with TNM stages, differential degree and lymph node metastasis (P<0.05). The promoter methylation frequency ofRASSF10 in GCA tissues was inversely related to its protein expression.Conclusion:Inactivation of RASSF10 caused by aberrantmethylation in the promoter region may be closely correlated with the GCA tumorgenesis.

BACKGROUND:In recent years, the researchers have studied the adjacent segment degeneration after cervical fusion. Several studies concerned the adjacent segment degeneration after anterior cervical corpectomy and fusion.
OBJECTIVE:To evaluate the correlative factors of adjacent segment degeneration after anterior cervical corpectomy and fusion.
METHODS:122 patients were included in the study from 126 patients who underwent anterior cervical corpectomy and fusion that operated by the same treatment team and involved a single vertebral body and the two plates between February 2009 and February 2012. The final fol ow-up period was 3 years. According to the degeneration progress of adjacent segment degeneration, these patients were divided into non-progression group and progression group. The gender, age, preoperative adjacent segment degeneration, cervical range of motion, upper and lower vertebral range of motion, surgical segment, titanium mesh subsidence, plate-to-disc distance, and cervical curvature index were compared between two groups. Logistic regression analysis was applied to analyze the correlative factors of adjacent segment degeneration.
RESULTS AND CONCLUSION:(1) There were significant differences in preoperative adjacent segment degeneration, postoperative cervical range of motion, postoperative upper and lower vertebral range of motion, and postoperative cervical curvature index (P<0.05), which were included in logistic regression analysis. (2) Logistic regression analysis regression model:adjacent segment degeneration=0.317× postoperative cervical range of motion+3.374×preoperative adjacent segment degeneration+1.862 × postoperative lower vertebral range of motion-0.795×postoperative cervical curvature index-16.481. Logistic regression analysis demonstrated that preoperative range of motion, postoperative cervical range of motion, postoperative lower vertebral range of motion and postoperative cervical curvature index were correlative factors of range of motion after adjacent segment degeneration (P<0.05). (3) These results indicated that preoperative adjacent segment degeneration, postoperative cervical range of motion, postoperative lower vertebral range of motion and postoperative cervical curvature index were correlative factors of adjacent segment degeneration. We should actively carry out effective measures to prevent the progress of the adjacent segment degeneration before, during and after anterior cervical corpectomy and fusion.
