Objective To investigate the relationship between Oxfordshire community stroke project(OCSP) classification and imaging classification in acute cerebral infarction. Methods Two hundred and thirty-six patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification,of all the 236 patients with acute cerebral infarction,28(11.9%) experienced total anterior circulation infarction(TACI),71(30.1%) partial anterior circulation infarction(PACI),94(39.8%) lacunar infarction(LACI),and 43(18.2%) posterior circulation infarction(POCI).The consistency was found in 171 cases(72.5%) between the OCSP classification and imaging classification,with the accuracy of 76%(25/33) for TACI,81%(34/42) for PACI,71%(81/114) for LACI and 66%(31/47) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy,and is well consisted with the imaging findings.

Objective To detect the expressions of PCNA, Cyclin D1 and P27, which were related to cell proliferation and cell cycle in gastric carcinoma and precancerous lesion of gastric mucosa. Methods Tissue microarray technique was applied to construct a tissue microarray containing gastric carcinoma, precancerous lesions and normal gastric mucosa. Diagnosis of the tissue in the microarray was pathologically confirmed. Immunohistochemical method was used to assess the expression of PCNA, Cyclin D1 and P27 in all the samples of tissue microarray. Results The expressions of PCNA and Cyclin D1 in gastric carcinoma, gastric hyperplasia, and intestinal metaplasia tissues were higher than that in normal gastric mucosa. The expressions of P27 in gastric hyperplasia, intestinal metaplasia and gastric carcinoma tissues were lower than that in normal gastric mucosa. Conclusion Gastric carcinoma, precancerous lesion and normal gastric mucosa tissues present different degrees of expression of PCNA, Cyclin D1 and P27, either with a increasing trend or a decreasing trend. These changes in expression are all closely related to gastric carcinogenesis.

Objective To review the clinical,histological and diagnostic aspects of 12 documented cases of nodular regenerative hyperplasia of the liver(NRHL),to make this condition be understood and dealt with better. Method Twelve NRHL cases were diagnosed based on liver biopsy from 300 portal hypertension patients who had been underwent splenectomy.Imaging studies were performed as part of the diagnostic evaluation.Clinical manifestation and biochemical tests were recorded at the time of diagnosis.Management and prognosis were also reviewed.Results Most patients were complicated with autoimmune disease,6 cases were diagnosed systemic lupus erythematosus and 1 was Crohn's disease and 1 suspected ulcerative colitis.Six cases were treated by prednisone and 3 cases by immunosuppressant.Eleven cases had suffered from portal hypertension.All cases had no history of viral hepatitis.Biochemical tests showed mild increase of liver enzyme and relative normal synthetic liver function.The histological finding was nodular in the hepatic parenehyma,with mild periportal fibrosis,intraportal lymphocytic infiltration,narrow and obstruction of branch of portal vein,and lack of hepatocyte necrosis.All cases were diagnosed liver cirrhosis and portal hypertension before operation.Management was directed to portal hypertension and varices bleeding with satisfactory results.Most of them keep a stable condition during the follow-up. Conclusion The NRHL was uncommon and its cause and pathogenesis was unclear,may be related with immune and hepatic blood circulation disorder.It should be considered in patients with unexplained portal hypertension and distinguished it from liver cirrhosis.Liver biopsy confirms the diagnosis.Management directed to portal hypertension may improve clinical condition.

The fused gene (PTH-HSA) of parathyroid hormone (PTH) gene and Human Serum Albumin(HSA) gene was amplified without linker by Overlapping PCR technology. The spliced gene was clone into Pichia pastoris secretory vector pPIC9K. With the help of promoter AOX1 and mat ? signal peptide, the PTH-HSA gene was designed to secretory expression.Linearized by restriction enzyme SalI, The recombinant plasmid pPIC9K/PTH-HSA was transformed into Pichia pastoris KM71 by electroporation. The recombinant strains which were identified by G418 and PCR analysis were induced by methanol to express protein PTH-HSA. The target protein was expressed in fermentation supernatant. Western blot analysis of the fusion protein showed that the expressed fusion protein PTH-HSA had the antigenicity of HSA.adenylate cyclase assay proved that the fused protein exhibited the bioactivity to stimulate cAMP synthesis The specific activity of broth was about 318IU/ml.
