In order to elucidate the causal agent of collar rot and its taxonomic status, the causal fungus was isolated and identified through a series of tests about its pathogenicity, morphology, culture feature and biological characteristics. The results indicated that the fungus was Fusarium venfrico- sum. It could grow at temperatures ranging from 10 to 40 ℃, and the most suitable temperature was 30 ℃. Its mycelium growth was inhibited above 40 ℃ or below 10 ℃. The accumulated water in wet season was the main reason for this disease occurrence.展开更多
背景颈托常规用于保持术后颈部刚性固定和避免并发症。目前未见文献报道关于颈托的不同佩戴时长对颈椎单开门椎板成形术后临床疗效的影响。目的比较不同颈托佩戴时长(2周vs 3个月)对单开门椎板成形术后患者颈部不适、功能恢复和影像学...背景颈托常规用于保持术后颈部刚性固定和避免并发症。目前未见文献报道关于颈托的不同佩戴时长对颈椎单开门椎板成形术后临床疗效的影响。目的比较不同颈托佩戴时长(2周vs 3个月)对单开门椎板成形术后患者颈部不适、功能恢复和影像学结果的影响。方法回顾性分析首都医科大学附属北京世纪坛医院脊柱外科2017年1月—2018年12月接受颈椎单开门椎板成形术并持续佩戴颈托3个月的患者(长期组)和2019年1月—2020年12月接受同样手术并持续佩戴颈托2周的患者(短期组)术后1年内的视觉模拟量表(visual analog scale,VAS)评分、颈部残疾指数(neck disability index,NDI)、日本骨科协会(Japanese Orthopaedic Association,JOA)评分以及术后颈部活动度(range of room,ROM)和门轴愈合率等方面的差异。结果研究共纳入69例患者,长期组33例,其中男20例,女13例,平均年龄(52.10±10.15)岁;短期组36例,其中男24例,女12例,平均年龄(55.92±9.48)岁;两组性别及年龄差异无统计学意义(P>0.05)。短期组患者术后3周和3个月时的VAS(3周:2.92±2.01 vs 1.48±1.13,P=0.003;3个月:2.67±1.71 vs 1.69±1.30,P=0.027)和NDI(3周:35.82±15.81 vs 26.41±15.77,P=0.016;3个月:33.56±12.75 vs 24.92±15.19,P=0.013)评分较长期组差,术后3个月时的ROM较长期组有显著优势(23.03°±4.70°vs 30.78°±7.38°,P<0.001),其余各时间点两组VAS、NDI和ROM均无统计学差异。两组患者术后JOA评分和门轴愈合率在各随访时间点上均无统计学差异。结论缩短颈托佩戴时间没有明显劣势,短期与长期佩戴颈托的患者,术后1年的功能评分、门轴愈合率和颈部ROM等方面无统计学差异。因此建议外科医师可以在术后评估患者状况后缩短颈托佩戴时长。展开更多
