ABSTRACT
Objectives To understand the vaccination situation of left-behind children in rural areas,provide the evidence for developing vaccination strategies for left-behind children.Methods The counties with population over 1,000,000 were selected from Anhui and Sichuan provinces respectively to conduct survery to the children who were born between the year 2003 and 2006,and had registration on vaccination book(card).Results The proportion of left-behind and outflow children are 17.94% and 6.05% respectively.The information about the children’s parents going out most came from village doctors. The proportion of the parents going out after children born was 51.60%,staying outside for more than 10 months was 78.50%. 67.97% pareets came back home during the spring festival,35.43% left-behind children went out with their parents.Conclusion Although the number of outflow children was smaller than the left-behind children,it was easy to develop immunization gap. It is the difficult part of management on EPI to migraut children. The information aboat the children’s parents going out mostly came from village doctors. It is impotant to mobilize the enthusiasm of doctors.It is especially essential that we should propagandize to the people with vaccination knowledge to the pareets came back home during spring festival.
ABSTRACT
Objective To observe the effect of Shengeyifei capsule on the inflammatory mediators in the airway and the pathology of the airway in the rat with chronic obstructive pulmonary diserse (COPD). Methods 60 SD rats were divided randomly into normal group, COPD model group, Jinshuibao control group and Shengeyifei groups. The COPD model was established by smoking and infusing lipopoly- saccharide (LPS). The level of interleukin-8 (IL-8) and tumor necrosis factor ? (TNF-?) in bronchoalveolar lavage fluid (BALF) were measured and the pathology of the airway and lung tissue was observed after treatment on the rats. Result The levels of IL-8 and TNF-? in Shengeyifei groups were lower than in COPD model group (P
ABSTRACT
The hair arsenic levels of nonoccupq-tional esposed nornal subjects,aged 20~55 years,were analysed by neutron activation analysis in Shaoguan.The median and geometric mean are 0.121?g/g and 0.118?g/ g respectively.These results are lower than many other reports in China.This paper proposes the 95% upper Limit value of hair arsenic level is 0.320?g/g.
ABSTRACT
Objective To evaluate the effect of mining waste water on drinking water quality and tumor mortality of villagers. Methods Analyse quality of drinking water sampled from well which only supply water to a family which the well belongs to and survey the death reasons of whole population in the polluted area and the control area. Results Mining waste water discharged by a mine contaminated the nearby river and impacted the drinking water quality of the nearby village also. Compared with the control, the concentration of lead, arsenic and mercury in drinking water of polluted area was much higher. The 5,year total mortality in polluted area and in the control was 3.09% and 1.55% respectively. Tumor mortality in polluted area was 50%, esophagus cancer mortality was 54.24%. Tumor mortality in the control area was 20% only and most tumors were liver cancer. Conclusion The adverse effect of mining waste water on drinking water quality and human health in polluted area has been seen.
