18F-FDG PET has more high sensitivity and specificity for diagnosis of malignant SPN and metastasis of lymphonodes,11C-choline PET can decrease the false positive rate of inflamed foci and is helpful to diagnosis of brain metastasis from the malignant SPN.
If the tu mor with an early UR more than1.735(2.856-1.121)and delayed UR>1.492(2.261-0.769)was pre sumed to be malig nancy,the percentage of sensitivities,specificities,and accuracies of 201 Tl scintigraphy in differentiating malignant lesions from benign lesions was95.35%,93.33%,and94.83%respectively.
Enhancement rate(E) reflected the blood kinetics of breast diseases. E 1min and E 3min were better than E 3min in differentiating benign and malignant breast diseases.
18F-fluorodeoxyglucose(18F-FDG) is the most widely used PET agent for imaging tumors. However,18F-FDG PET showed a relatively high false positive rate when it is used to differentia the malignant and benign lesions.
CT and X-ray were respectively 100% ,100% and 80. 0% in detecting metastatic tumors, 94. 4%, 92. 3% and 83. 3% in primary malignant bone tumors, 100% , 90. 9% and 60% in benign bone tumors, 100%, 100% and 83. 3% in tumorlike lesions,100% , 100% and 80.0% in inflammatory diseases.

The rank order for the spectrum of death causes of non-war wounds had changed significantly among troops at a certain area in China from 1950 to 1986. In 1980s, the chief death causes were malignant tumors,accidents and acute infectious diseases, respectively. When the rank order among the troops was compared with that among the citizens at the same area during this period, we have found that the former was similar to the latter for malignant tumors,but the former was higher for accidents and ac...
Two inhibitory substances were isolated from the calf spleens and the porcine blood, which were respectively designated to as Granulopoiesis Inhibitory Factor (GIF) and Plasma Nonspecific Immunosuppressive Protein (PNIP).The biological activity of GIF and PNIP was examined.GIF could remarkably inhibit GM-CFU of the BaBL/C mouse bone marrow cells but had no effect on the 3H-TdR incorporation into the mouse spleen cells and mouse lymphoma L5178Y cells.PNIP could significantly suppress the proliferation of the...
