The Guangdong-Hong Kong-Macao Greater Bay Area is witnessing a surge in economic development,showcasing robust resilience in the co-agglomeration of producer services and manufacturing industries,along with the increasingly evident impact generated by such co-agglomeration.Based on the panel data collected from ten cities in the Guangdong-Hong Kong-Macao Greater Bay Area(excluding Zhaoqing)spanning from 2010 to 2020,we examined the formation mechanism for industrial co-agglomeration in the area from three dimensions:industrial correlation,spatial correlation,and policy guidance.Our analysis was based on a vertical correlation model and was validated using the seemingly unrelated regressions(SUR)method.The findings are as follows:(a)There currently exists no spatial correlation between the producer services and manufacturing sectors in the area,and the correlation between the two remains limited to the former providing specialized services to the latter.(b)Policy guidance has a positive impact on the location selection of industries within the area.By implementing a comprehensive range of favorable policies,local governments can provide effective and scientifically guided recommendations regarding the location of producer services and manufacturing sectors.Therefore,it is crucial to foster the collaboration between producer services and manufacturing sectors and further enhance the co-agglomeration between the two sectors.In addition,the government authorities should also strive to enhance its economic governance capacity,thereby facilitating the formation of such co-agglomeration. 展开更多

目的:探讨右美托咪定复合胸椎旁神经阻滞(TPVB)对老年患者胸腔镜肺叶切除术后认知功能障碍的影响。方法:选取2021年6月-2022年1月在漳州市医院行胸腔镜肺叶切除术老年患者100例,随机分为对照组(n=50)和观察组(n=50);麻醉诱导前,两组均... 目的:探讨右美托咪定复合胸椎旁神经阻滞(TPVB)对老年患者胸腔镜肺叶切除术后认知功能障碍的影响。方法:选取2021年6月-2022年1月在漳州市医院行胸腔镜肺叶切除术老年患者100例,随机分为对照组(n=50)和观察组(n=50);麻醉诱导前,两组均于超声引导下行TPVB,对照组注入0.375%罗哌卡因20 ml,观察组注入0.375%罗哌卡因20 ml+右美托咪定0.8 μg/kg;两组均采取相同的麻醉诱导和麻醉维持方案,术后均予以自控静脉镇痛。记录两组镇痛药物使用情况;于术前1 d及术后1、3、7 d评估两组简易智力状态量表(MMSE)评分,并统计术后7 d内两组术后认知功能障碍(POCD)发生情况;于术前1 d及术后1 d行血清神经元特异性烯醇化酶(NSE)、S100β蛋白水平的测定。结果:观察组丙泊酚、舒芬太尼及瑞芬太尼的消耗量均少于对照组,术后补救镇痛率低于对照组,差异均有统计学意义(P<0.05)。术后1、3 d,观察组MMSE评分显著高于对照组(P<0.05);术后7 d内观察组POCD发生率为6.00%,显著低于对照组的22.00%(P<0.05)。术后1 d,两组S100β蛋白和NSE水平均升高(P<0.05),但观察组S100β蛋白和NSE水平低于对照组(P<0.05)。结论:右美托咪定复合胸椎旁神经阻滞TPVB可改善老年患者胸腔镜肺叶切除术后认知功能,减少POCD发生。 展开更多
