Research Progress Towards the Liquid Chip Technology in Detection of Animal Infectious Diseases

Liquid chip technology is a novel biomolecular detection technology which integrates laser technology,flow cytometry,digital signal processing and traditional chemical technology.It is widely used in various immunological analysis and nucleic acid detection.Single and mutiplex analysis are supported,with protein and nucleic acid targets detected in a variety of detection methods in high throughput manner.It has advantages of high throughput,easy operation,wide range of application,good repeatability,high specificity,less sample needed,high sensitivity and stablility,and low cost.Therefore,they are gradually replacing the traditional detection and quantitative pathogen methods,such as Real-time fluorescent quantitative nucleic acid amplification detection system (qPCR),enzyme-linked immunosorbent assay (ELISA) and other detection methods.Animal infectious diseases seriously endanger the development of the breeding industry,futhermore,some zoonoses such as highly pathogenic avian influenza also pose a serious threat to human health.An efficient and sensitive diagnostic system will help to screen a large number of samples during the outbreak of infectious diseases and prevent the spread of infection.The development of liquid chip technology provides a new platform for high-throughput detection and disease prevention.In this review,the principle and advantages of liquid chip technology are briefly described.The research progress of liquid chip technology in the detection of animal infectious diseases,including pigs diseases,poultry diseases,rabbit diseases,dog diseases,rodent diseases and other animal infectious diseases are summarized.We believe that in the future,this technology will become an important analytical and testing tool in clinical diagnosis,basic research,new drug development,judicial identification,food health supervision,biological weapons prevention and other fields.The development of this technology will greatly promote the research and development of life science.

路灯照射对大豆生长发育和产量的影响

通过对淮北五马路沿线夏大豆的田间调查分析表明：受路灯照射的影响，夏大豆株高增加，开花期、成熟期推迟，底荚部位上升，单株生产力下降。且距离越近，植株越高，开花、成熟越晚，底荚部位越高，单株生产力越低。
