目的寻找一种简单、准确的方法建立动脉的不同剪切力动物模型,为研究剪切力在心血管系统中的作用及机制奠定基础。方法 30只SD大鼠随机分为3组,即颈总动脉结扎组、股动静脉吻合组和髂总动脉结扎组,每组又分为手术组和假手术组(对照组),利用多普勒超声仪检测手术前后动脉血流,估算血流剪切力的变化。利用免疫荧光组织化学法检测不同剪切力下血管内皮e NOS的表达情况。结果颈总动脉结扎法大鼠死亡率高;股动静脉吻合法手术耗时长,且因动脉太小不易测得股动脉血流;单侧髂总动脉结扎手术可以使双侧髂总动脉分别形成不同血流剪切力。单侧髂总动脉结扎术后,结扎侧髂总动脉内皮e NOS免疫反应性减弱,而结扎对侧e NOS免疫反应性增强。结论单侧髂总动脉结扎手术简单易操作,髂总动脉血流速度通过多普勒超声仪可获得,是制作不同剪切力动物模型的最佳方法。

portion of alpine meadows has been and will continue to be cultivated due to the concurrent increasing demands for animal-and crop-oriented foods and global ***, it remains unclear how these long-term changes in land use will affect nitric oxide(NO) emission. At a field site with a calcareous soil on the Qinghai-Tibetan Plateau,the authors measured the year-round NO fluxes and related variables in a typically wintergrazed natural alpine meadow(NAM) and its adjacent forage oat field(FOF). The results showed that long-term plow tillage, fertilization and growing forage oats significantly yielded ca. 2.7 times more(p < 0.01) NO emissions from the FOF than the NAM(conservatively 208 vs. 56 g N/(ha·year) on average). The spring freeze–thaw period and non-growing season accounted for 17%-35% of the annual emissions, respectively. The Q10 of surface soil temperature(Ts) was 8.9 in the NAM(vs. 3.8 in the FOF), indicating increases of 24%–93% in NO emissions per 1–3 °C increase. However, the warming-induced increases could be smaller than those due to land use change and management practices. The Tsand concentrations of ammonium, nitrate and water-extractable organic carbon jointly explained 69% of the variance in daily NO fluxes from both fields during the annual period(p < 0.001). This result indicates that temporally and/or spatially distributed NO fluxes from landscapes with calcareous soils across native alpine meadows and/or fields cultivated with forage oats can be predicted by simultaneous observations of these four soil variables.
