0.05),the odds ratio(OR)being 0.873,[95% confidential interval(CI):0.428～1.782].(3)The relationship between ischemic stroke and the risk factors was illuminated by the Logistic Regression analysis.The results showed that there was no significant difference of the positive rate of IgA antibody between the case group and control group.Conclusion There may be not relationship between CP IgA antibody and ischemic stroke.There is no relationship between IgA CP antibody and the other risk factors of ischemic stroke.

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.

Objective To investigate the effects of improved end-to-end invagination pancreaticojejunostomy on the occurrence of pancreatic fistula after pancreaticoduodenectomy.Methods The clinical data of 396 patients who received pancreaticoduodenectomy at the Cancer Hospital of Shandong Province from January 2001 to January 2011 were retrospectively analyzed.All patients were divided into the improved group(235 patients)and traditional group(161 patients)according to different anastomotic methods.All the operations were done by the same surgical group,and the digestive tract was reconstructed by the Child method.Patients in the improved group received improved end-to-end invagination pancreaticojejunostomy,and patients in the traditional group received traditional end-to-end anastomosis.The volume of operative bleeding,operation time,incidence of pancreatic fistula and duration of hospital stay of the 2 groups were compared.All data were analyzed using the t test,chisquare test or Fisher exact probability.Results The operative blood loss,operation time and duration of hospital stay were(383 ±56)ml,(7.2 ± 1.0)hours,(21 ±3)days in the improved group,and(381 ±39)ml,(7.0 ± 0.5)hours,(22 ± 5)days in the traditional group,with no significant difference between the 2 groups(t =0.388,1.680,-1.835,P ＞ 0.05).No operative death was detected in the 2 groups,and the overall incidence of pancreatic fistula was 7.6％(30/396).The incidence of pancreatic fistula of the improved group was 0(0/235),which was significantly lower than 18.6％(30/161)of the traditional group(P ＜ 0.05).Patients complicated with pancreatic fistula in the traditional group were cured by drainage,somatostatin administration and parenteral nutrition.Conclusion Improved end-to-end invagination pancreaticojejunostomy can significantly reduce the incidence of pancreatic fistula after pancreaticoduodenectomy.

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 attaine a new mode of pathological data managed by computer. Methods:All pathological data were collected into the system of pathological data management. Results:It was helpful to phomote the work officiency and easy for pathological data check up. Conclusion:By using computer operation, we can update the document collection efficiently. It is helpful for data review, and research.

Purpose To investigate the expression of GATA3 in breast tumors and its clinical significance. Methods Immunohisto-chemistry EnVision method was used to detect the expression of GATA3 protein in 132 cases of breast malignant tumor tissue, 29 cases of breast benign tumor tissue, 35 cases of breast carcinoma adjacent tissue. Besides, the GATA3 expression level was compared with several clinicopathological parameters. Result (1) All the breast normal tissues expressed GATA3, while 77% of the breast cancer tissue were found to be GATA3 positive. (2) GATA3 did not expressed in diffuse large B cell lymphoma and spindle cell malignant tumor of breast. (3) In the triple negative breast cancer, the expression of GATA3 was lower than that of any other subtypes of breast carcinoma (χ2 =29. 354, P<0. 001). Conclusion The positive expression of GATA3 is correlated to classification and grade in breast tumor. Detection of the expression of this biological maker may provide a valuable marker for the differential diagnosis and prog-nostic of breast carcinoma.

Purpose To investigate the clinicopathologic features, diagnosis and differential diagnosis of ovarian juvenile granulosa cell tumor (JGCT).Methods The history records, pathologic features and immunophenotype of 8 cases of JGCT were retrospectively evaluated and their prognosis was achieved by follow-up.Results The age of patients ranged from 6～21 years old,with an average age of 15.1 years.The main clinical manifestations included an abdominal mass, ascites and isosexual pseudoprecocity. Cut surface of the tumor was typically solid with cysts formed. The histopathological changes displayed solid nests, diffuse sheet, multiple round or ovoid follicles in variable size.Macrofollicles could be seen in some cases.The follicular pattern consisted of small cystic cavities containing eosinophilic secretions. The tumor cells were round or polygonal, medium in size. The tumor cells had abundant pale or slightly eosinophilic cytoplasm, round nuclei with fine chromatin. Nuclear grooves were inconspicuous.Mitosis figures could be found. Immunohistochemical results showed that the tumor cells expressed inhibin-α,CD99,vimentin; while Melan-A,calretinin and S-100 were positive staining in part of the cases.CKpan,EMA,PLAP,Syn and CgA were negative in all the cases.Conclusions Ovarian juvenile granulosa cell tumor is a rather rare, low malignant tumor with good prognosis. Its diagnosis depends on the histologic and immunohistochemical findings and clinical features. Its differential diagnosis includes adult granulose cell tumor, hypercalcaemic type small cell carcinoma, carcinoid and dysgerminoma.
