Objective To evaluate the target killing effect and metastasis prevention effect of soluble Fas combined with PKC inhibitor on the growth of human colorectal carcinoma implant in nude mice. Methods Orthotopic implantation and metastasis model of human colorectal carcinoma was reproduced in nude mice. Tumor tissue of tumor cell line HR-8348 with positive expression of FasL was implanted to the colonic wall of nude mice. After one week of tumor growth, mice were randomly divided into four groups according to the different agents injected into the peritoneal cavity. Twelve mice were in each group. The mice in the combined treatment group (recombinant soluble Fas coupled with PKC inhibitor + 5-Fu) were injected intraperitoneally 100?l (3mg/ml) recombinant soluble Fas coupled with PKC inhibitor and 0.5 mg of 5-Fu. (On the day of 0, 4, 8, 12 and16). At the same time, a group of tumor bearing mice were given recombinant soluble Fas coupled with PKC inhibitor only, and another group with 5-Fu only, and in the control group only normal saline was given. One month after implantation, tumor weight, inhibition rate and the presence of metastasis were evaluated respectively after the mice were sacrificed. Results Compared with control group, the orthotopically implanted tumors were significantly reduced in weight in mice treated with 5-Fu, recombinant soluble Fas coupled with the PKC inhibitor, and combined treatment, with respective inhibited rates of 43.1%, 79.9%, and 86.3%. Liver metastasis was also inhibited with significant decrease in incidence in 5-Fu group, recombinant soluble Fas coupled with the PKC inhibitor, and combined group compared with that in control group (75.0% vs 36.4%, 16.7%, and 0%). The incidence of peritoneal metastasis was also decreased significantly in 5-Fu, recombinant soluble Fas coupled with PKC inhibitor, and combined treatment compared with that in control group (100% vs 45.5%, 16.7%, and 8.3%, P

Objective To detect serum protein spectrum in gastric cancer, screen the serum proteins related to gastric carcinoma and build auxiliary diagnosis model with SELDI-TOF-MS, Methods The serum proteomic fingerprints were detected by SELDI-TOF-MS and CM10 proteinchip. The sera came from 50 first visit gastric cancer patients who were diagnosed by pathological method and 16 healthy peo- ple. The data were analyzed by Biomarker Wizard Software and the proteomic fingerprint of gastric carcinoma model was developed by BPS (biomarker pattern software). Results Compared with the healthy people group, there were 34 significant different protein peaks in the gas- tric carcinoma group. And the diagnosis model composed with 6 proteins (M/Z values were 6016, 6744, 2822, 4474, 7892 and 3242) could classify the 2 groups correctly. In the test group, the sensitivity and specificity were 96% and 93.75% respectively, the accuracy was 95.45%. Conclusion SELDI-TOF-MS method show features such as microcontent, fast and high- resolution etc. It could be utilized to screen significant proteins and develop an auxiliary diagnosis model in gastric carcinoma, which may be used to diagnose this disease.

Purpose To detect the expression of NKX2. 2 protein in gastrointestinal, pancreatic and esophageal neuroendocrine tumors and the correlation between the expression of NKX2. 2 and the clinicopathologic parameters. Methods 41 cases of gastrointestinal, pancreatic and esophageal neuroendocrine tumors were collected. The expression of NKX2. 2, Syn and CgA in neuroendocrine tumor samples were checked by using immunohistochemical staining. Results The positive expression of NKX2. 2 protein was localized in the nucleus. NKX2. 2 protein showed positive staining in neuroendocrine tumors of the seven original sites. In the four cases of normal pancreatic islet cells also showed strongly diffuse positive nuclear staining. The positive rates of NKX2. 2, Syn and CgA protein in the small intestine, rectum, pancreatic neuroendocrine tumors were 100%, 100% and 46. 7%, respectively. The positive rates of NKX2. 2 in foregut, midgut and hindgut were 30% and 87% (χ2 = 11. 09, P=0. 001). Positive NKX2. 2 protein expression was not associated with gender, age group, grade, tumor size and lymph node metastasis. Conclusion NKX2. 2, as a new type of neuroendo-crine markers, is obviously superior to CgA in the diagnosis of neuroendocrine tumors in the small bowel, rectum and pancreas. NKX2. 2, Syn and CgA, a panel approach may be beneficial to enhance diagnostic accuracy of the neuroendocrine tumors.

Objective Primitive neuroectodermal tumor (PNET) is a rare malignant small round cell tumor .This paper aimed to study the clinical and pathological features of primary pulmonary primitive neuroectodermal tumor . Methods We collected 2 cases of primary pulmonary PNET to review the clinical and pathological features .Immunohistochemical staining was used to detect immune mark-ers, and fluorescence in situ hybridization (FISH) was applied to detect EWS translocation. Results 2 patients were aged 33 years and 17 years.Microscopically, the tumor cell was composed of single small round cells in diffusion or in distribution of sheets or beams , with scant cytoplasm , oval or spindle-shaped nucleus , high mitotic count .Irregular tumor necrosis scattered in the tumor along with visi-ble rosette structure.Immunohistochemical study showed that the tumor cells were positive for CD 99, FLI-1 and Syn, while CKpan, EMA, Desmin, CgA, TTF1, CD34 were negative.EWS/FLI1 translocations were detected positive in both the cases .2 patients died 7 months and 32 months after operation , respectively . Conclusion Primary pulmonary PNET is rare , so the selection of appropriate im-mune markers (CD99, FLI-1, Syn) and FISH for the detection of EWS translocation helps to improve the accuracy of diagnosis .

Objective To explore the morphological, immunohistochemical characters and prognosis in one case of patients with cutaneous anaplastic large cell lymphoma complicated with acute myeloid leukemia (C-ALCL-AML). Methods The histopathology, immunohistochemical markers and follow-up information of one case of ALCL-AML was analyzed and the correlated literature was reviewed. Results The patient, 69 year-old, female, was initially present with shin lesion on one finger and abnormal myelogram. The histopathology of shin lesion showed that tumor cells were composed of large cells with abundant cytoplasm,the nuclei were large and irregular, and were infiltrated by Neutrophil and eosinophil. The CD30,CD3 and CD43 of tumor cells were positive, but ALK negative by immunohistochemical method. The number of WBC in peripheral blood was 15.5×109/L and 51 archaeocytes were in every 100 karyotes. Bone marrow aspiration detection showed that bone marrow was hyperplasia and the ratio of myeloblast was 78 %. This patient was diagnosed as C-ALCL-AML, partly differentiation type(AML-M2a). Conclusion C-ALCL-AML is very rare. Its diagnosis is dependent on clinical data, histopathology and immunohistochemical markers. The first choice of treatment is chemotherapy, but its prognosis is poor.
