METHODS:The gastric cancer cells MKN-45 were exposed to a CO2 and helium environment maintained at different pressures (0, 5, 10 and 15 mmHg). The cells were exposed to simulated pneumoperitoneum environment for 4 h, and pH of the culture media was measured after it was moved to normal conditions for 0, 2, 4, 6 and 8 h. Proliferation viability of MKN-45 was examined by 3-4,5Dimethylthiazol-2-yl,5-diphenyltetrazolium bromide or triazolyl blue (MTT) assay after it was moved to normal conditions. Apoptotic ratio was measured by Annexin V-FITC/PI double labelled staining. RESULTS:The pH of media was acid and recovered to normal after 4 h in the CO2 group while it was basic in the helium group. There was no difference between CO2 groups (under 10 mmHg ) and control group (P > 0.05) in the proliferative viability of the cells. The cultured cells exposed to 15 mmHg CO2 environment grew more slowly than control group from 4 to 7 d (P < 0.01 ) while there was no difference from 1 to 3 d (P > 0.05). The proliferative viability in helium group was not obviously different from the control group (P > 0.05). The apoptotic ratio of the cultured cells was markedly higher than that of the control group (P < 0.01) at 10 and 15 mmHg CO2 insufflation pressure. In helium group, the apoptotic ratio was not obviously different from the control group (P > 0.05). CONCLUSION:There is no obvious effect in the proliferation and apoptosis of MKN-45 cells under 10 mmHg CO2 insufflation pressure and helium in any pressure. Fifteen mmHg CO2 insufflation pressure can inhibit the proliferation of the cells and improve apoptosis.展开更多

METHODS: Formalin-fixed, paraffin-embedded tissues were cut into 5 urn thick sections and routinely stained with hematoxylin and eosin. Some slides were also stained with Alcian-PAS. Antibodies used were primary antibodies to pancytokeratin, cytokeratin 7, cytokeratin 20, epithelial membrane antigen, vimentin, smooth muscle actin and CD-117. RESULTS: We observed three patients who presented with multiple metastases from large cell bronchial carcinoma to small intestine. Two of them had abdominal symptoms (sudden onset of abdominal pain, constipation and vomiting) and in one case the tumor was incidentally found during autopsy. Microscopically, all tumors showed a same histological pattern and consisted almost exclusively of strands and sheets of poorly cohesive, polymorphic giant cells with scanty, delicate stromas. Few smaller polygonal anaplastic cells dispersed between polymorphic giant cells, were also observed. Immunohistochemistry showed positive staining of the tumor cells with cytokeratin and vimentin. Microscopically and immunohistochemically all metastases had a similar pattern to primary anaplastic carcinoma of the small intestine. CONCLUSION: In patients with small intestine tumors showing anaplastic features, especially with multiple tumors, metastases from large cell bronchial carcinoma should be first excluded, because it seems that they are more common than expected.展开更多

Arnong the 38. 12 had low-malignancy tracheal tumors, 11 had benign tracheal tumors, 14 had low malignancy bronchial tumors and 1 had a benign bronchial tumor. Fifteen operations were perforrned on 12 patients with low-malignancy tracheal tumors, including local resection of the tumor and tracheal wall in 4 and curettage of the tumor plus electrical cauterization in 10. Postoperative radiotherapy was used as an adjuvant treatment in 8 patients with adenocystic carcinoma. Eight patients have survived for more than 5 years and 3 patients have survived for longer than 10 years postoperatively. All 11 patients with benign tumors received curettage of the tumor and were followed up for an average of 6. 5 years. Among them, 9 are still alive. Of the 14 patients with low malignancy bronchial tumors, 5 underwent curettage of the tumor plus electrical cauterization through incision of the main bronchus or intermedial bronchus, and 7 underwent lobectomy or pneumonectomy. The authors conclude that the correct diagnosis rate can be increased by enhancing recognition of this disease and applying tracheal tomography and bronchoscopy.展开更多
