Objective To investigate the expression of PTPN13 in human gastric cancer and gastric cancer SGC-7901celllineanditsassociationwithproliferationandinvasion.Methods 106casesgastriccancertissuesamples and matched normal peritumorial tissues were collected .SGC-7901 cells were cultured and divided into two groups including pcDNA3.1-PTPN13 transfection group and without transfection group .Immunohistochemical technique was used to detecte protein expression of PTPN 13.The association of PTPN13 expression with tumor location , tumor size , depth of invasion and tumor metastasis were analyzed .The survival rate of patients with different PT-PN13 expression was calculated by Kaplan-Meier curves.CCK-8 assay was used to estimate the proliferation chan-ges.Using Trans-well assay analyzed the invasion of SGC-7901 cells.Moreover, Western blot was performed to de-tect the markers of EMT including E-cadherin, Snail and MMP9.Results Immunohistochemistry showed the expression rate of PTPN13 in gastric cancer tissues was lower than normal tissue (31 %vs 83%, P<0.05).The expression of PTPN13 in patients was related to with different tumor size , depth of invasion and tumor metastasis (P<0.05).The 2-year survival rate of patients with negative PTPN13 expression were lower.Overexpression reduced both proliferation and invasion in SGC-7901 cells.Up-regulated PTPN13 may increase E-cadherin level but decreases the level of Snail and MMP9 .Conclusions PTPN13 plays a role in gastric cancer tissue and cells as a tumor suppressor.Lower PTPN13 may predict a poor prognosis.PTPN13 may be used as therapy target in gastric cancer.

Objective To assess the value of video-assisted thoracoscopic mini-invasive lobectomy in the treatment of pulmonary benign lesions or malignancies. Methods A retrospectively analysis on clinical data of 35 cases of video-assisted thoracoscopic mini-invasive lobectomy, which were performed from February 2002 to June 2006, was made. The pathological diagnosis included 31 cases of peripheral lung cancer (T_1N_0-1M_0), 3 cases of bronchiectasis, and 1 case of atelectasis combined with pulmonary abscess. The procedures included 30 cases of anatomical lobectomy and 5 cases of non-anatomical lobectomy. Results No conversion to open surgery was required. The operation time was 85~210 min (115?35 min) and the intraoperative blood loss was 150~450 ml (210?55 ml). Postoperatively, acute respiratory failure was encountered in 2 cases, and mechanical ventilation was given for 3 and 5 days, respectively. Acute myocardial infarction occurred in 1 case, which was cured by early-stage thrombolysis. No postoperative complications were seen in the remaining 32 cases. The closed chest drainage was maintained for 2~10 days (mean, 5.4 days). In 3 cases of pulmonary benign lesions, follow-up checkups for 41, 33, and 13 months, respectively, found no long-term complications. In 25 cases of lung cancer, follow-up observations were made for 3~53 months (mean, 15.2 months), including 3~12 month in 6 cases, 12~24 months in 9 cases, 24~36 months in 7 cases, and 36~53 months in 3 cases. There were 4 cases of death due to cancer recurrence or metastasis (16%), 2 cases of with-tumor survival (8%), and 19 cases of disease-free survival (76%), respectively. Conclusions Video-assisted thoracoscopic mini-invasive lobectomy is a feasible and safe procedure for peripheral lung cancer and benign lung diseases.
