[Analysis of Vegetation Change and Influencing Factors in Southwest Alpine Canyon Area].

The southwest alpine canyon area is a typical ecologically fragile area. Understanding the characteristics of vegetation change here and its influencing factors can provide a theoretical basis for formulating countermeasures for ecological environment construction in the southwest alpine canyon area and has practical significance for realizing the harmonious and unified development of the regional economy, environment, and ecology. Based on the data set of NDVI, socio-economic factors, and natural factors from 2000 to 2019, the spatial and temporal variation and stability characteristics of NDVI in the southwest alpine canyon area were analyzed by using the methods of unary linear regression, Hurst index, geographic detector model, and coefficient of variation, and the influencing factors of the spatial differentiation of NDVI were also discussed.

Development of pristane induced mice model for lupus with atherosclerosis and analysis of TLR expression.

Objectives: This study was designed to establish a murine model of lupus with atherosclerosis, and to investigate the expression of Toll-like receptors (TLRs) in the aorta and kidney.

Methods: The 9-week-old female ApoE-/- and C57BL/6 mice were randomly divided into a ApoE-/- pristane treated group (group A), ApoE-/- control group (group B), C57BL/6 pristane treated group (group C) and C57BL/6 control group (group D). Each mouse was given either a single intraperitoneal injection of 0.
