Objective adiponectin Methods To investigate the effects of clenbuterol （CLB） on the expression of （ADP） in adipocytes. 3T3-L1 pre-adipocytes were induced into mature adipocytes, and then randomly divided into four groups based on doses of CLB： 0 12mol/L （group A, as the control）, 0.5 12mol/L （group B, low-dose group）, 5 μmol/L （group C, mid-dose group）, and 50 μmol/L （group D, high-dose group）, respectively. These four groups were cultured for both 12 h and 24 h. After CLB exposure, the effects of CLB on the expression of ADP in adipocytes were detected by qPCR and Western blotting analysis, and cell viability was quantified by the methyl thiazolyl tetrazolium assay. Results At 12 h, there was no difference in the expression of ADP between group A and group B or C （P〉0.05）. With the increase of CLB doses, the expression level of ADP in group D was lower than that in group A （P〈0.01）. After 24 h of incubation, compared with group A, there was a greater decrease in the expression of ADP in group B （P〈0.05）, and this suppression was more remarkable in group C or D （P〈O.O1）. At 12 h, viability of the cells in group B had no difference compared with group A （P〉 0.05）. A significant decrease of cell viability was counted in group C or D （P〈0.05）. At 24 h, with the increasing doses of CLB, viability of the cells showed more severe decrease in three experimental groups compared with the control （P〈0.01）. Conclusion After CLB exposure, the expression of ADP could be down-regulated and the decrease was more severe with the increasing doses of CLB.

Over the years,the high magnetic induction of industrial Mn-added electrical steel is assumed to be the enhancement of{100}texture derived from its austenite-ferrite phase transformation during hot rolling(phase transformation(PT)method).However,it is still undetermined without straightforward experimental *** reason for{100}texture improvement of Mn-added electrical steel is experimentally confirmed due to the recrystallization induced by the austenite-ferrite phase transformation during hot ***,a more promising methodology to further improve{100}texture and formability of hot-rolled electrical steel is promoted by the control of hot rolling deformation condition(shear deformation(SD)method).The results show that the nucleation mechanisms of{100}oriented recrystallized grains are different in the samples by SD and PT methods,which are in-depth shear deformation and austenite-ferrite phase transformation,*** this case,coarse{100}oriented recrystallized grains and low residual stress are obtained in the sample by SD method,which is responsible for its superior{100}texture and *** contrast,the sample by PT method forms fine recrystallized grains with random orientations and accumulates severe residual stress.

土壤微塑料(MPs,粒径小于5 mm)对农业环境和粮食安全生产的潜在威胁,已成为人们关注的热点问题之一,但关于我国农用土壤MPs污染特征及其影响因素的系统研究还很少.利用Meta分析方法,依据从2020~2023年的85篇文献中提取的6 694个样本土壤的MPs及其相关的环境因子(温度、降水量、土壤酸碱度、有机碳)和社会经济因子(常住人口、人均地区生产总值、人均工业生产总值、人均耕地面积)的数据,综合分析了我国6个行政区农用土壤的MPs污染特征及影响土壤MPs积累的关键因素.结果表明,土壤MPs有(半)透明、黑色、白色、黄色、蓝、绿和红等6种颜色;有碎片、纤维、薄膜、颗粒和泡沫等5种形状;粒径大小在0.01~5.0 mm之间;有聚乙烯(PE)、聚丙烯(PP)、聚苯乙烯(PS)、聚酯(PES)、聚对苯二甲酸乙二醇酯(PET)、聚氯乙烯(PVC)、人造丝(RY)、聚丙烯腈(PAN)和聚酰胺(PA)等9种类型.不同区域土壤MPs的丰度梯度为:中南地区>西北地区>西南地区>华东地区>华北地区>东北地区.(半)透明(27.6%)、碎片(32.2%)、粒径在0.01~0.5 mm(66.3%)和PE(37%)类型的MPs检出率最高.土壤微塑料特征是自然环境因子(温度、降水量、土壤酸碱度、有机碳)与社会因子(常住人口、人均地区生产总值、人均工业生产总值、人均耕地面积)共同作用的结果 .
