ABSTRACT
OBJECTIVE@#To determine the normal range of the 33 elements (Li, Be, B, Mg, Al, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Zr, Mo, Ag, Cd, Sb, Cs, Ba Au, Hg, Tl, Pb, Th and U) in human whole blood of general population in Hunan province.@*METHODS@#Blood samples were analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) to determine the normal range. The influences of district, gender and age to the element content in blood samples were also observed.@*RESULTS@#The normal range of 33 elements in blood samples from general population in Hunan province were obtained. Gender was shown to statistically influence the concentrations of B, Mg, Ca, Ti, Mn, Fe, Co, Cu, Zn, As, Se, Rb, Sr, Ag, Cd, Cs, Hg and Pb (P < 0.05), while age was shown to influence the concentrations of Co, Ni, Cs and Hg in women (P < 0.05) as well as Cu, Se and Hg in men (P < 0.05).@*CONCLUSION@#Although there are variables in different districts, the normal ranges of trace element in blood of the four cities in Hunan province are established.

<p><b>OBJECTIVE</b>To investigate anemia status and correlation infection factors in rural regions of Hebei province and to find out evidence for preventing and controlling anemia.</p><p><b>METHODS</b>A random-sampling survey was conducted among 3367 houses in Hebei rural areas. The investigation involved economic levels, ages, education levels and occupations of 11,627 questionnaire. The hemoprotein and serum iron were measured. Unconditional logistic regression was performed.</p><p><b>RESULTS</b>The anemia prevalence rate was shown up to 8.4% in rural regions of Hebei province, and in men and women was 5.5% and 11.0%, respectively;mainly in infant (< 2 years old, 27.2%) child bearing age women, the anemia prevalence rate was 11.0%-16.0%. The analysis showed that the main risk factors of anemia were sex and serum iron.</p><p><b>CONCLUSION</b>The anemia prevalence is highest in infant and child bearing age women;supplying of iron should be an important measure for preventing and controlling anemia.</p>
