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.

Objective To investigate the effect of Clopidogrel on the plasma endothelin(ET)and calcitonin gene related peptide(CGRP)in patients with unstable angina pectoris(UAP).Methods Patients with UAP were divided into two groups,the regular treated group(n =50)was treated with Isoket and the Dansben group(n =50)was treated with combined Isoket and Clopidogrel.The plasma ET and CGRP were measured before and after treatment by radioimmunoreactive assay.Data were compared between the two groups and also compared with those measured in 20healthy subjects for control.Results ET level was significantly higher and CGRP level was lower in UAP patients than that in healthy subjects(P < 0.05).After Clopidogrel treatment,ET was significantly decreased(P < 0.01)and CGRP increased(P <0.05)in combined treatment group compared with patients received lsoket only.Conclusion Clopidogrel was an effective drug for UAP treatment,which could efficiently regulate the ET and CGRP metabolism.

Objective To establish the high performance liquid chromatography(HPLC) fingerprint of wuzi yanzong pills. Methods HPLC was performed on Agilent Extend C18 column (250 mmí4. 6 mm,5 μm) with a gradient elution system using acetonitrile:methanol (101)-0. 4% phosphoric acid as the mobile phase. The column temperature was set at 30 ℃ and the flow rate was 1. 0 mL·min-1 . The eluate was detected at the wavelength of 254 nm. Chromatographic peaks were identified by LC-MS method. Results Nine common peaks in wuzi yanzong pill samples were identified by comparing their LC-MS data with those of reference compounds and related reference reports. The HPLC fingerprint of wuzi yanzong pills was finally developed based on the analysis of sixteen batches of samples and their similarities were above 0. 93. Conclusion This method has high precision,stability and repeatability. This study could be used for overall quality assessment of wuzi yanzong pills.
