Association between body-constitution type and vascular endothelial dysfunction: A cross-sectional study in an adult obese/ overweight population

Objective:To measure vascular endothelial function (VED) in obese/overweight people grouped according to the constitutional theory of traditional Chinese medicine (TCM).We wished to predict the risk of VED and cardiovascular diseases in obese/overweight populations.Methods:This was a cross-sectional study.Eighty-six obese/overweight volunteers from Beijing Chao-Yang Hospital were enrolled and divided into four groups based on body-constitution type:phlegm dampness (PD);phlegm dampness with blood stasis (PDBS);qi-deficiency (QD);balance (BA).Height,weight,waist circumference and hip circumference were measured,and percent body fat and reactive hyperemia index (RHI) calculated.Levels of vascular endothelial growth factor (VEGF),von Willebrand factor (vWF) and plasma endothelial-1 (ET-1) were detected by immunohistochemistry.Results:The RHI and vWF levels in the PDBS group were significantly lower than those in the BA group and QD group (P <.05),but there was no significant difference compared with the PD group (P >.05).These two indicators displayed no significant differences among BA,QD,and PD groups (P >.05).There was no significant difference among the four groups in level of ET-1 or VEGF (P >.05).Conclusion:Of the four indicators selected,the RHI and vWF displayed significant differences between the PDBS group and BA group,and between the PDBS group and QD group.Hence,in an obese/overweight population with different constitutional types,compared with BA and QD groups,a relatively higher risk of suffering from VED was detected in the PDBS group.Meanwhile,this study provides the experimental basis for confirming the feasibility of constitutional classification in obese/overweight population.

Necessity and Feasibility of Developing Low Carbon Agriculture in Xuzhou City

According to the characteristics of low carbon economy and low carbon agriculture at home and abroad,and combining with actual situations of agricultural development in Xuzhou City,the necessity of developing low carbon agriculture in Xuzhou City is analyzed by the perspectives of its agricultural production conditions,agricultural modernization,comprehensive competitive power,ecological civilization and low carbon economy. Simultaneously,the feasibility of developing low carbon agriculture in the city is discussed through low carbon technology,rural land management model,agricultural input channel,agriculture-related scientific research system,agricultural research transformation mechanism and rural personnel training program to provide some references for promoting the rapid and sound development of low carbon agriculture in Xuzhou City.

The Connotation Construction of Agriculture-related Majors in the Vocational Schools

Taking the case of vocational schools in Xuzhou City,we analyze the challenges and opportunities faced by the connotation construction of agriculture-related majors in vocational schools. And we discuss the focus of connotation construction of agriculture-related majors,by establishing one theme,building two aspects,deepening three reforms and highlighting four tasks,aiming to make the connotation construction of agriculture-related majors get somewhere,and provide strong support for agricultural science and technology innovation. Finally we put forth measures for the connotation construction of agriculture-related majors.
