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.

A moderately halophilic bacterium strain DF-B6 capable of degrading Tween 20 was isolated from solar saltern brine by plate method.Based on the phenotype,physiological and biochemical character-istics,and the phylogenetic analysis of 16S rDNA sequence,strain DF-B6 was identified as Idiomarina.The substrate specificity test showed that the lipolytic enzyme from strain DF-B6 was an esterase,and not a li-pase.The maximum esterase activity was observed in 8% NaCl concentration at 50?C,pH 8.0.The effect of various divalent cations was studied on the activity of esterase from Idiomarina sp.DF-B6 at the concentra-tion of 10 mmol/L,Mg2+,Ca2+ and Mn2+enhanced the esterase activity,while Zn2+,Fe3+ and Cu2+ inhibited its activity.

Background and purpose: Alveolar soft part sarcoma (ASPS) is a rare malignant neoplasm characterized by slow growth and indolent behavior, and most of the patients had metastases in diagnoses. This study was to define clinical features and assess prognostic factors of ASTS. Methods: Between January 2003 and December 2008, there were 15 patients with ASTS who received treatment and were followed up in the Department of Orthopedic Ontology of Peking University People's Hospital. We retrospectively analyzed the clinical factors of the disease related to prognosis: gender, age, tumor size, primary tumor site, metastatic sites, local recurrence, the roles of postoperative radiotherapy and postoperative chemotherapy. Resnlts: At a follow-up from 7 to 76 months, only 2 patients had local recurrences after excision, but there was a high incidence of pulmonary metastases. Only 6 patients achieved disease free survival, 5 patients died of metastases or other complications. The five-year overall survival rates was 41.7%, and the median survival time was 42.0 months. Univariate analysis and Cox regression analysis revealed that tumor size, tumor primary site and metastases at diagnoses were prognostic factors, but not gender and age, Conclusion: Alveolar soft part sarcoma is a high grade malignant soft tissue neoplasm with frequent metastases to lung, bone or brain. Tumor size, primary tumor site and metastases at diagnoses are some of the prognostic factors. Chemotherapy or radiotherapy after surgery have no benefit to the survival in our analysis. Further prospective studies are needed to clarify the best strategy for the treatment of ASPS.

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.

Objective To investigate technique,effect,complications of limb salvage surgery for malignant tumors of the proximal tibia involving the fibula.Methods Between November 1998 and February 2010,32 patients with malignant tumors of the proximal tibia involving the fibula underwent limb salvage surgery in our institute.There were 21 males and 11 females,aged from 10 to 66 years (average,23.4years).There were 23 cases of osteosarcoma,5 cases of chondrosarcoma,1 case of malignant giant cell tumor,and 3 cases of soft tissue sarcoma.All patients received en bloc resection of tumor including proximal tibia and fibula.During operations,ligation of anterior tibial vessels was performed in 14 patients,anastomosis of posterior tibial vessels in 1 patient,both ligation of anterior tibial vessels and anastomosis or replacement of posterior tibial vessels in 5 patients.The common peroneal nerve was resected in 4 patients,and the deep peroneal nerve was resected in 5 patients.The reconstruction methods included prosthetic replacement in 24 patients,replacement with inactivated autograft-prosthesis composite in 5 patients,and replacement with inactivated autograft in 3 patients.The caput mediale musculi gastrocnemii flap was transferred to reconstruct soft tissue defect in 14 patients,while caput laterale musculi gastrocnemii flap was transferred in 1patient.Results All patients were followed up for 11 to 159 months (average,39.4 months).Local recurrence occurred in 6 patients (18.8％).The overall 5-year survival rate was 51.2％.Fourteen patients died of tumor metastasis,2 survived with tumor,and 16 patients survived without tumor.Variant complications occurred in 15 patients (46.9％).The complications included ischemia of the lower leg in 4 patients,peroneal nerve palsy in 12 patients (permanent palsy in 9 patients and temporary palsy in 3 patients),wound healing problem in 4 patients,deep infection in 1 patient,and periprosthetic fracture in 1 patient.The mean MSTS 93 score was 21.6 points (72％).Conculusion The indications of limb salvage surgery for malignant tumors of the proximal tibia involving the fibula should be restricted.Although complications are encountered frequently,most patients have acceptable postoperative function.
