RESUMEN
Through field investigation, UPLC-MS/MS technology and MaxEnt model were performed to predict the suitable distribution area for red huajiao (Zanthoxylum bungeanum maxim.) in China from 2021 s to 2060 s, and evaluate the effects of climate factors on the quality of red huajiao. The results demonstrated that mean temperature of the coldest quarter and min temperature of the coldest month were the most important environmental variables influencing red huajiao distribution. Suitable habitats for red huajiao were located mainly in dry and hot valley zone in the Qinba Mountains and the semi-humid and semi-arid areas of the Loess Plateau. The amides contents were higher in high suitability areas, while it was decreased in medium and low suitability areas, and temperature, wind speed and precipitation played a key role in their accumulation. This investigation was of great significance for the planting area optimization, quality control, benefit improvement and industrial development of red huajiao.
RESUMEN
OBJECTIVE: To explore the effect of the tri-cuff vascular anastomosis for simplifying the surgical procedure and improving the success rate. METHOD: Sixty recipient Wistar rats were randomized into experimental group and the control group, the former was subjected to the tri-cuff vascular anastomosis for heterotopic small bowel transplantation while the latter had vascular anastomosis using classical methods. The effects of the two methods for anastomosis were compared. RESULTS: The tri-cuff vascular anastomosis was superior to the classical methods in view of the total operation time, arterial anastomosis time, and hot-ischemia time of the small bowel graft. CONCLUSION: Compared with the classical methods, the tri-cuff vascular anastomosis is safer and time-saving.
