东北乡村经济振兴是东北乡村振兴的前提和基础。目前,东北乡村经济振兴取得了一定成果,新产业新业态不断涌现,农村农业生产智能化、数字化、科技化,农业供给侧结构性改革深化推进,但也存在着科技投入不足、民营经济动力不足、农村集体经济相对薄弱、高层次人才缺乏、三次产业融合不足、基础设施建设还需提高等问题。人才是推进东北乡村经济振兴的智力支撑,因此要针对东北乡村经济振兴的阻碍因素,优化人才配置,引育并举,不断丰富东北乡村经济振兴的“智库”。

中国骨伤 2024年第6期37卷 553-559页

作者：李军科马续彬李亮马晴王旭东邯郸市第一医院创伤骨科河北邯郸056000

目的:构建预测骨质疏松性椎体压缩性骨折(osteoporotic vertebral compression fractures,OVCFs)经皮椎体成形术(percutaneous vertebroplasty,PVP)后残余背痛(residual back pain,RBP)的列线图。方法:回顾性分析2020年1月至2022年12月245例接受PVP治疗的OVCFs患者的临床资料,男47例,女198例,年龄65~77(71.47±9.03)岁,根据是否发生RBP分为RBP组与无RBP组。收集患者的性别、年龄、合并症情况、骨折发生节段、身体质量指数(body mass index,BMI)、骨密度(bone mineral density,BMD)、视觉模拟评分(visual analogue scale,VAS)、Oswestry功能障碍指数(Oswestry disability index,ODI)等一般资料;以及术前与术后24 h的影像学参数,包括椎体前缘高度(anterior vertebral height,AVH)、椎体前缘高度比(anterior vertebral height ratio,AVHR)、Cobb角、椎体内真空裂(intravertebral vacuum cleft,IVC)、胸腰筋膜(thoracolumbar fascia,TLF)损伤、椎旁肌脂肪变性、骨水泥注射量、骨水泥渗漏、骨水泥弥散形态、椎体前缘高度恢复比(anterior vertebral height recovery ratio,AVHRR)、Cobb角变化等。对以上因素进行单因素分析,再采用多因素Logistic回归模筛选术后发生RBP的独立危险因素,并完成Nomogram模型的构建与验证,分别采用受试者工作特征(receiver operating characteristic,ROC)曲线和校准曲线进行模型的预测性能和准确性的判定,另采用Hosmer-Lemeshow(H-L)检验进行评估,计算ROC曲线下面积(area under curve,AUC),使用Harrell一致性指数(C指数)评价模型的预测效能,使用决策曲线分析(decision curve analysis,DCA)评价模型的临床实用性。结果:RBP组34例,无RBP组211例。两组性别、年龄、合并症、骨折节段、BMI、BMD、VAS及ODI、AVH、AVHR、Cobb角等比较,差异均无统计学意义(P>0.05)。单因素分析结果显示:RBP组6例出现IVC,无RBP组13例,RBP组IVC比例高于无RBP组(χ2=5.400,P=0.020);RBP组6例出现TLF损伤,无RBP组11例,RBP组TLF损伤比例高于无RBP组(χ2=7.011,P=0.008);RBP组椎旁肌脂肪变性3-4级为18例,无RBP组为41例,RBP组高于无RBP组(χ2=21.618,P2级(χ2=15.124,P2级以及骨水泥弥散形态为团块型为PVP术后发生RBP的独立危险因素,本研究所构建的PVP术后发生RBP的风险预测模型具有较好的预测性能和较好的临床实用性。
