ABSTRACT
Objective This article takes a cosmetics factory in Yichang City as an example, uses a variety of methodologies to explore methods of health impact assessment and provides methodological references for future health evaluation of related public policies. Methods By analyzing the environmental assessment report of the cosmetic renovation project, an indicator system was established and expert consultation meetings were conducted to score the impact of the corresponding indicators on health. The impact of the renovation project of the factory on the factory workers, surrounding residents and the sustainable development of the environment was analyzed by means of the Kaiser model with the risk matrix and the Borda value. Results The risk values of the five influencing factors of industrial wastewater, domestic wastewater, industrial waste gas, industrial waste and noise were 5.11%, 5.43%, 10.6%, 6.71% and 7.02% respectively. All the influencing factors were in the green zone of the risk matrix. The Borda values of the five influencing factors of industrial waste water, domestic waste water, industrial waste gas, industrial waste residue and noise were 4, 5, 10, 7 and 5 respectively. Conclusion The multiple methodologies adopted in the factory renovation project are feasible, and can provide new ideas for the health impact assessment of public policies in the future.
ABSTRACT
Objectives To investigate the risk factors of acute renal injury (acute kidney injury) in patients with acute left heart failure.Methods Clinical data of 188 patients with acute left heart failure who were admitted to our hospital were retrospectively analyzed.Logistic regression analysis was used to assess the risk factors for AKI.Results Among 188 patients with acute left heart failure,incidence of acute kidney injury was 33.51％.Univariate and Multivariable logistic regression analyses showed that the independent predictors of acute kidney injury were lower baseline eGFR (OR=4.294,P ＜ 0.001) and anemia (OR=3.573,P=0.006).Conclusions The incidence of acute left heart failure complicated with AKI was high.Basic state of renal function and anemia were the independent risk factors for AKI.
ABSTRACT
Objective To investigate the effects of erythropoietin (EPO) on complement 3a (C3a)-induced renal tubular epithelial to mesenchymal transition. Methods The HK-2 cells were divided into 6 groups namely control group,EPO group,TGF-β group,TGF-β+EPO group,C3a group and EPO+C3a group.The mRNA and protein expressions of α-SMA,E-cadherin and C3 were investigated by RT-PCR,Western blot and immunofluorescence respectively. Results Compared with control group and EPO group,the mRNA and protein expressions of α-SMA in HK-2 cells were up-regulated after the intervention of C3a or TGF-β (all P＜0.05).On the contrast,the mRNA and protein expressions of E-cadherin were down-regulated(P＜0.05),the mRNA and protein expressions of C3 were enhanced (all P＜0.05).However,all those above effects of C3a or TGF-β were inhibited after the intervention of EPO (all P＜0.05). Conclusion EPO is capable of suppressing the epithelial to mesenchymal transition induced by C3a.
