Cordance together with the pituitary staining intensity, testing was divided into four levels: i) No pituitary staining was unfavorable, 0 points; ii) weakly optimistic (+), 1 point; iii) moderately positive (++), two points; and iv) strongly optimistic (+++), three points. In accordance with the percentage of PP, testing was divided into 4 levels: i) Adverse: No pituitary staining, 0 points; ii) good: Pituitary ten , 1 point; iii) PP 11-50 , two points; iv) PP 51-80 , three points; and v) PP 80 , four points. The constructive rate of samples was calculated by the percentage of positive samples in the total number of samples. Ten randomly selected fields were viewed by high magnification, x400, calculated as a percentage of PP samples. Imply SD was the average value from the PP and its normal deviation was the expression intensity. Statistical analysis. SPSS 19.0 software (IBM SPSS, Armonk, NY, USA) was utilized for statistical evaluation, as well as the qualitative information had been analyzed and tested by analysis of variance (ANOVA) test, t-test and two test. The Fisher’s precise probability system was made use of for the 4 grid data of who didONCOLOGY LETTERS 14: 2165-2169,Table I.
