Exploration and Practice of Cultivation Pathway of Agricultural Professionals under the Background of Rural Revitalization

The comprehensive implementation of the rural revitalization strategy puts forward new requirements for agricultural professionals.In the context of rural revitalization,local vocational colleges should adjust their cultivation models for agricultural professionals in accordance with industrial development,and propose effective cultivation paths from four aspects:building a reasonable and scientific professional structure system,optimizing the construction of teaching staff,strengthening the construction of school-enterprise platforms,and consolidating the"three rural"sentiment,in order to better serve the local economy,strive to cultivate more rural revitalization talents for society,and ensure the maximum adaptation to the development requirements of China s new rural construction.

成人腭大孔解剖与腭穹隆形态相关性的CBCT影像研究

目的 研究成人腭大孔(greater palatine foramen,GPF)解剖位置及其与腭穹窿高低的相关性,为涉及上腭区域的临床操作提供理论依据。方法 从昆明医科大学附属口腔医院影像科收集2020年1~6月符合纳入标准的180名成人患者的CBCT图像,评估双侧360例腭大孔相对于上颌磨牙的位置以及距上颌腭中缝线和釉牙骨质界的距离,并分析不同腭穹窿高低与腭大孔分布的关联。结果 腭大孔在第2磨牙腭侧、第3磨牙近中腭侧、第3磨牙腭侧的分布率分别是21.39%、21.11%和57.50%。男性和女性腭大孔与腭中缝(midsagittal suture,MMS)的距离(GPF-MMS)分别为(16.31±1.18) mm和(15.82±1.32) mm,腭大孔至对应磨牙釉牙骨质界(enamelo-cemental junction,CEJ)的距离(GPF-M)为(17.11±2.50) mm和(15.79±2.57) mm,均显示男性大于女性(P <0.05)。GPF-MMS在高腭组中略低于低腭组(P <0.05);然而,GPF-M在高腭组中明显高于低腭组(P <0.05)。结论 成人腭大孔位置与其性别和腭穹隆高低有关。
