In order to assess the incidence or iron deficiency anemia and molybodosis among children of our district, hemoglobin and ZPP of 555 children aged from 6 to 7 were tested, and serum ferritin (SF) and Serum Pb of some of them were determined. The results show that the incidence of occult anemia (ID+IDE) is 44.1%, say 245 cases including 107 cases of iron deficiency anemia (IDA) is 19.3% (While molybdo-sis is 48.6%). It concluded there is a high incidence rate of iron deficiency and molybdosis(especially the latter) among school age children of our district. Precautions should be taken against the diseases.
A copper-mediated tandem addition/cyclization/carbon–carbon cleavage reaction for the convenient synthesis of 2-acyl trisubstituted furans has been developed.

Abstract Background There are few studies focused on the correlations between ambient air pollution and abdominal pain, especially in emergency departments in China. Method: Daily data (from January 1, 2016 to December 31, 2018), including air pollution concentration (SO 2 , NO 2 , PM 2.5 , PM 10 , CO, and O 3 ) and meteorological variables, for daily emergency room visits (ERVs) were collected in Wuhan, China. We conducted a time-series study to investigate the potential correlation between six ambient air pollutants and ERVs for abdominal pain and their effects, in different genders, ages and seasons. Results A total of 16,306 abdominal pain ERVs were identified during the study period. A 10-µg/m 3 increase in concentration of SO 2 , NO 2 , PM 2.5 , PM 10 , CO, and O 3 corresponded respectively to incremental increases in abdominal pain of 6.12% (95% confidence interval [CI]: -0.44-13.12), 1.65% (95%CI: -0.25-3.59), 1.12% (95%CI: -0.18-2.44), 0.38% (95%CI: -1.09-1.87), 9.87% (95%CI:3.14–17.05) and 1.11% (95%CI: 0.03–2.21). We observed significant correlations between CO and O 3 and daily abdominal pain ERVs increase, and positive but insignificant correlations between the other pollutants and ERVs. The effects were stronger mainly for females (especially SO 2 and O 3 ) and younger people (especially CO and O 3 ). The correlations of PM 2.5 and PM 10 were stronger in cool seasons, while the correlation of CO was stronger in warm seasons. Conclusion Our time-series study suggested that short-term exposure to air pollution (especially CO and O 3 ) was positively correlated with ERVs for abdominal pain in Wuhan, China, and that their effects varied by season, gender and age. These data can add evidence on how air pollutants affect the human body, and may prompt hospitals to take specific precautions on polluted days and maintain order in emergency departments made busier due to the pollution.
