Introduction Characterized as persistent and progressive pulmonary function declining,chronic obstructive pulmonary disease (COPD) can be accompanied by a systemic inflammatory response.A variety of psychiatric and somatic comorbidities can occur to the patients,such as depression,nutritional disorders,cardiovascular disease,and lung cancer.It is imposing great impacts on the quality of patients' life.In 2010 alone,the economic burden of COPD in the world was as high as 2.1 trillion dollars [1].The high prevalence,mortality,and morbidity have made this disease a major public health problem in socio-economic development with a rapidly aging population in China. 展开更多

China's pig industry has been well developed un-der the background of this era. However, the number of pig diseases increases due to the influence of many factors, and highly pathogenic porcine reproductive and respiratory syndrome(HP-PRRS) is one of the very common diseases, causing growing mortality rate of pigs. The disease increases the economic loss of pig industry to a large extent, and brings difficulties in prevention and control of pig diseases. The staff must analyze and sum-marize the basic characteristics of pig diseases, and combine some practical problems in prevention and control of pig disease to find effective mea-sures. The scope and scale of pig production in different parts of China have been continuously expanded under the background of further develop-ment of pig industry in the new era. But for pig production, pig disease has been a problem that delays its further development. Related personnel must analyze and summarize the status quo of HP-PRRS, to find effective prevention measures and strategy. 展开更多
