It has been a major topic for the reform on higher medical education and teaching to cultivate medical students' professional information literacy so asto make them equipped with the information competence required for disease control or medical research.In this thesis,the concept of professional information literacy for medical students was introduced,and by analyzing the relationship of information literacy education and medical education modes,countermeasures and methods of cultivating medical students' professional information literacy by combining the reform on medical education and teaching were put forward.

OBJECTIVE: To establish a simultaneously detecting method for 9 kinds of anion in workplace air by ion chromatography. METHODS: Nine kinds of anions in workplace air include fluoride ion,chloride ion,nitrite ion,bromide ion,nitrate ion,sulfate ion,phosphate ion,oxalate denominationbl and iodide ion were sampled with sodium carbonatesodium bicarbonate( concentration 3. 2,1. 1 mmol/L respectively),separated by the anion column,detected by the conductivity detector and quantified by external standard method. RESULTS: The linearity of the 9 anions in the corresponding mass concentration range was good( correlation coefficient > 0. 999). The detection limit was 0. 02-0. 18mg/L and the marking recovery was 96. 0%-100. 5%. The within-run relative standard deviation( RSD) was 0. 3%-2. 5%,and the between-run RSD was 0. 4%-3. 1%. All the sampling efficiencies were > 96. 8%,and the samples could be stored at room temperature for 5 days. CONCLUSION: The method has good accuracy,high sensitivity,with simple and rapid operation,and can simultaneously measure various anions in the air of workplace.

OBJECTIVE: To understand the exposure of occupational hazards, occupational and mental health status of high-speed railway locomotive drivers. METHODS: A total of 150 male high-speed railway locomotive drivers from Nanchang Railway administration were selected as experimental group, and 80 male ordinary train drivers were selected as control group by using a judgment sampling method. The occupational disease hazard testing and occupational health examinations were conducted in drivers of these two groups. The mental health status survey was conducted using the Symptom Checklist 90(SCL-90). RESULTS: The noise, power frequency electric field, formaldehyde, benzene, toluene, xylene and carbon dioxide in all the work place of these two groups were in line with the national occupational health standards. The exposure noise intensity of the experimental group was lower than that of the control group [(70.5±3.7) vs(77.4±4.1) dB(A), P<0.05]. The detection rates of hypertension and chronic gastritis were higher in the experimental group(18.7% vs 34.7%, 26.2% vs 42.0%, P<0.05). The detection rate of high frequency hearing loss decreased in the experimental group compared with the control group(22.5% vs 10.7%, P<0.05). The total score of SCL-90 in the experimental group was higher than that in the control group [(169.5±6.1) vs(148.0±6.0) score, P<0.01]. The positive rate of psychological symptoms was higher in the experimental group than that of the control group(41.3% vs 23.8%, P<0.01). CONCLUSION: The concentration/intensity of occupational disease hazards in the workplace of high-speed railway locomotives drivers is within normal limit. The occupational health status of high-speed railway locomotive drivers is generally good, but attention should be paid to their occupational mental health hazards.
