Feline calicivirus (FCV) is an important and highly prevalent pathogen of cats that causes feline respiratory disease. The reverse genetic systems for FCV have been established in national and international laboratories since 1995. This technique has been used widely in FCV basic research and good progress has consequently been made to determine the relationship between viral genome structures and the function of their proteins, the expression of foreign proteins, virus-host interactions, and viral pathogenic mechanisms. In this article,we review the state of progress with regards to the establishment and application of the FCV reverse genetic operating system,which will provide a useful reference tool for future related research.

Objective:
To examine the effects of obesity and central obesity on hypertension, so as to provide insights into the prevention and control measures of hypertension.
Methods:
From September to December 2018, residents at ages of 35 to 75 years were sampled using the multi-stage random sampling method in Baiyin District, Baiyin City, Gansu Province, and subjected to questionnaire surveys and physical examinations. The interaction between obesity/central obesity and hypertension was evaluated using logistic regression analysis. The synergy index ( SI ), relative excess risk due to interaction ( RERI ) and attributable proportion due to interaction ( AP ) were calculated using Excel compiled by Andersson et al.
Results:
A total of 6 246 questionnaires were allocated and 6 169 valid questionnaires were recovered, with an effective recovery rate of 98.77%. The respondents included 3 038 men ( 49.25% ) and 3 131 women (50.75%), with a mean age of ( 52.05±8.78 ) years. There were 832 respondents with obesity ( 13.49% ) and 2 278 with central obesity ( 36.93% ). The crude and standardized prevalence rates of hypertension were 35.89% and 33.05%, respectively. Multivariable logistic regression analysis showed that obesity ( OR=2.020, 95%CI: 1.705-2.393 ) and central obesity ( OR=1.622, 95%CI: 1.433-1.836 ) were statistically associated with hypertension. There was no multiplicative interaction between obesity or central obesity and hypertension ( OR=1.011, 95%CI: 0.655-1.560 ), and no additive interaction was detected between obesity or central obesityand hypertension ( SI=1.405, 95%CI: 0.815-2.424; RERI=0.658, 95%CI: -0.298 to 1.614; AP=0.201, 95%CI: -0.075 to 0.476 ).
Conclusions
Obesity and central obesity increase the risk of hypertension; however, no interaction is detected between obesity or central obesity and hypertension.

Vascular biomechanics mainly explores how vascular cells perceive mechanical stimuli,how mechanics affects the development of diseases,and the exploitation of various mathematical models to analyze the effects of mechanical factors on diseases.In recent years,researches in the field of vascular biomechanics are developing rapidly,and various research teams have analyzed the mechanical and biological processes of blood vessels from different directions,in order to gain a deeper understanding of the regulatory mechanisms of vascular biomechanical factors affecting the progression of various vascular diseases,and provide a theoretical basis based on the mechanobiology for the prevention and treatment of cardiovascular and cerebrovascular diseases.This article summarizes and discusses the recent research hotspots and emerging trends in the field of vascular mechanobiology based on domestic and foreign expert teams and combined with the work of this research team,thus providing a systematic framework for grasping hotspots and exploring new research directions in the field of vascular mechanobiology.
