The results suggest the growing domestic and international market demands are main factors to the development of strategic emerging industries.R&D investment,technology innovation and new products output also play important roles in promoting the development of strategic emerging industries. The objective conclusions are obtained through theoretical and empirical analyses.展开更多
目的探讨极/超低出生体质量儿自发性肠穿孔(SIP)的临床特征、治疗及临床转归。方法选取2015年1月至2018年12月南方医科大学附属深圳妇幼保健院收治的胎龄<32周、出生体质量<1500 g SIP患儿(SIP组)30例,选取同期、同胎龄及同出生...目的探讨极/超低出生体质量儿自发性肠穿孔(SIP)的临床特征、治疗及临床转归。方法选取2015年1月至2018年12月南方医科大学附属深圳妇幼保健院收治的胎龄<32周、出生体质量<1500 g SIP患儿(SIP组)30例,选取同期、同胎龄及同出生体质量的无肠穿孔早产儿(对照组)66例。回顾性分析SIP组的临床资料,比较SIP组和对照组的基线资料和短期临床转归。结果纳入的早产儿共1270例,其中SIP组30例,胎龄22~31周的SIP总发病率为2.36%(30/1270),出生体质量400~1499 g的SIP总发病率为2.62%(30/1145),胎龄为22~25周、26~27周、28~31周的发病率分别占11.76%、2.02%和1.01%,出生体质量为400~749 g、750~999 g、1000~1499 g的发病率分别占12.96%、3.39%和1.00%。死亡率为30.00%。平均穿孔日龄为(5.90±1.97)d。SIP组静脉营养相关性胆汁淤积症(PNAC)发生率高于对照组(P<0.05)。保守治疗15例(50.0%),保守联合手术治疗3例(10.0%),手术治疗10例(33.33%)。出院时存活率分别为73.33%、100.00%、50.00%,总体存活率为63.33%。结论SIP常见于超低出生体质量儿。胎龄越小、出生体质量越低,其发病率越高,且穿孔日龄早,死亡率高。保守治疗可作为首选方案。展开更多
