Objective To study occupational hazards effects of electric welding,and evaluate protective measurements for different occupational hazards. Methods During 2008,occupational health services for 11 factories with shield carbon-dioxide arc welding work were provided,including surveillance of the work environment and surveillance of workers’health. Surveys of workers’health through various types of health examinations were carried out. Four hundred and thirty-three welding workers of 11 factories were included. Results The concentrations of 17 welding fume samples and 6 manganese dioxide samples were over the released limits of national standard,the maximum was 5.5,1.6 times of the limit respectively. The exceeding standard rate. of welding fume had positive correlation with the density of welding equipment(r= 0.72,P=0.01) and negative correlation with the ventilation area(r =-0.63,P =0.04) .The examination results showed that nobody suffered occupational diseases or occupational contraindications. Conclusion For the environmental risk factors existed in the electric welding operation site,more attention should be paid to the potentially occupational adverse effects of electric welding.

Objectives To investigate the dynamic change of galectin-1 in myocardium of mice with viral myocarditis (VMC). Methods A total of 58 male BALB/c mice were selected and randomly divided into CVB3 group (n=50) and control group (n=8). Mice in CVB3 group were infected with 0.10 ml 10-5/L CVB3 through intraperitoneal inoculation, and 8 mice were killed on day 7, 10, 14 and 28 respectively after inoculation. Mice in control group inoculated with 0.10 ml eagle reagent was killed on day 28. The myocardial pathological changes were observed using light microscope. In addition, expressions of serum galectin-1 were detected by ELISA and expressions of myocardial galectin-1 were detected by real-time quantitative-polymerase chain reaction (RQ-PCR).

A simple preparative strategy was proposed for the preparation of water-soluble, bright blue-emitting carbon nanoparticles ( CNPs ) at different temperatures by hydrothermal treatment using bean curd residue as carbon source for the first time. When the temperature reaches 240 ℃, quantum yield ( QY) can be up to 15. 24%. Most importantly, such fluorescent CNPs can be served as an effective sensing platform for label-free sensitive and selective detection of Fe3+ions with a detection of limit as low as 50 nmol/L, which is nearly 2 orders of magnitude lower than the maximum level of Fe3+ions in the drinking water permitted by the European Community. These outstanding properties give promising potential for reliable detection of Fe3+ in intracellular fluid and water samples, even bioimaging and optical imaging without being hazard in the future.

The rennin angiotensin system has been recognized for many years as a key regulator in systemic blood pressure and the metabolism of water and salt. Angiotensin converting enzyme 2(ACE2) is the first human homolog of angiotensin converting enzyme which efficiently hydrolyze the angiotensin Ⅱ to vasodilator angiotensin 1-7.ACE2 is now implicated in cardiovascular,renal, lung disease and serves as a receptor for Severe Acute Respiratory Syndrome coronavirus.
