Objective To explore whether and how the medical students' performance in English and biochemistry studies on their exam scores in toxicology basics (in short:toxicology) with allEnglish questions.Methods The correlations between scores of toxicology exam with all-English questions and scores in college English test band 6 (CET6) and biochemistry test of 187 students in the eight-year medical program were analyzed.Results Score of toxicology exam was positively correlated with scores of CET6 and biochemistry tests to some degree ( the correlation coefficients were 0.359 and 0.413 respectively,P ＜ 0.01 ) ; the students who passed CET6 had higher score in toxicology exam than those who did not pass CET6 (P ＜ 0.01,by t-test).Conclusion Passing CET6 and having a good command of related subjects may be essential for adapting to all-English exam questions.

Emergency in public health is one major issue relating to the national economy and the people's livelihood.In dealing with the key technologies of detects,diagnosis,disinfection,prevention and control,it is wise to syncretize the correlated subjects in nucleus,chemistry and biology,improve the support condition of teaching,strengthen the reform of teaching contents,add some lessons of emergency treatment,make emergency equipments,and form the ability of rapid diagnosis on the spot and precise identifying in lab,for cultivating the students'capability of spot handling,organization and command,and furthermore exploring and practicing the training pattern of the public heath talent with high quality and emergency ability in our country.

This study aimed to establish human IFN-gamma (hIFN-gamma) in vitro release assay and to apply it in diagnosis of human tuberculosis. Human IFN-gamma gene was cloned and expressed in Escherichia coli. The recombinant hIFN-gamma was purified and used as immunogen to immunize mice and rabbits respectively. Monoclonal and polyclonal antibodies were respectively developed and a sandwich ELISA was established. The heparized whole blood from 111 active tuberculosis patients and 292 clinical healthy controls were collected. The blood was stimulated with tuberculosis specific fused antigen ESAT-6/CFP-10 and the plasma was collected for IFN-gamma detection. The sensitivity for tuberculosis diagnosis was 95.5%, whereas the positive detection rate for the healthy controls was 16.7%. There was a significant difference between the patients and healthy controls (P<0.01) indicating that this assay had a high sensitivity and specificity, and thus could be promising in tuberculosis diagnosis.
