目的探讨同侧腮腺内同时原发不同病理类型肿瘤的临床表现、组织病理学特点、诊断治疗及预后。方法报道1例同侧腮腺内腺淋巴瘤和基底细胞腺瘤同时发生的病例,并结合文献对腮腺多原发肿瘤的诊疗进行回顾分析。结果患者发现右腮腺区包块1个月,术前扪及右腮腺浅叶肿物,结合核磁共振检查诊断为右侧腮腺浅叶及深叶肿瘤。全麻下行右侧腮腺深叶及浅叶肿物和部分腺体切除术+面神经解剖术,术后病理报告右侧腮腺浅叶为腺淋巴瘤,深叶为基底细胞腺瘤伴囊变。手术效果良好,无并发症,术后随访1年未见复发。复习文献结果表明,腮腺多原发性肿瘤是指双侧或者单侧同时存在2种或以上的肿瘤。该疾病以手术治疗为主。结论同侧腮腺内同时原发不同病理类型的肿瘤病例罕见,需完善影像学检查防止漏诊,手术为首选治疗方案,良性肿瘤预后良好。

为了明确区域风险源的空间分布及生产安全事故的空间相关性,探索区域生产安全事故的时空演变规律。以四大经济区划分下我国国内(不含港澳台,下同)的31个省(自治区、直辖市)2005—2020年的面板数据作为研究样本,通过多种时空特征分析方法可视化展示我国国内生产安全事故的时空分布特征,并运用探索性空间数据分析(exploratory spatial data analysis,ESDA)方法分析其空间相关性演化过程。研究结果表明:生产安全状况的空间分布由“高-高”集聚转为“低-低”集聚为主,事故空间分布不平衡问题显著;目前事故空间集聚稳步提高,区域差异减小,对周边地区有正面空间溢出效应,东部沿海地区通过“涓滴效应”逐步改善了周边省份和地区的生产安全状况。研究结果可为具体调整各区域生产安全状况提供参考。
