Increased level of polymerase III transcribed Alu RNA in hepatocellular carcinoma tissue.

There have been extensive observations that RNA containing repetitive elements accumulates in transformed cells and tumor tissues. In the present study, we first obtained result consistent with previous observations by in situ hybridization. Then we used primer extension analysis to determine the level of polymerase III directed Alu RNA and found an increased expression of Alu RNA in hepatocellular carcinoma.

Set theory in diagnostic reasoning.

BACKGROUND: Regarding diagnostic reasoning, the currently taught Bayesian theory is a form of hypothetical-deduction reasoning. Using set theory, we offer syllogism reasoning instead of hypothetical-deductive reasoning and establish an online diagnostic expert system model based on this diagnostic methodology. METHODS: Concepts of set theory were employed to demonstrate diagnostic reasoning. ASP, Vbscript and Microsoft Access were used to establish the expert system and data of 50 cases from Shanghai pulmonary hospital were put into the program to test its efficiency. CONCLUSION: Diagnostic procedure is type of syllogism rather than hypothetical-deductive reasoning.
