Zhongguo shiyan zhenduanxue, 2018 食管炎是临床上最常见的食管疾病,一般是由食管黏膜受到刺激或者损伤,继而引发食管黏膜充血水肿所致。根据病因不同可以分为反流性食管炎、真菌性食管炎、病毒性食管炎、化脓性食管炎等,其中真菌性食管炎是特殊的食道炎症,主要由于霉菌侵入食管粘膜组织导致食管感染,属消化道念珠菌病之一。食管破裂是食管病变的严重并发症,病情严重者可能引起穿孔,继而导致纵膈感染,病情进展迅速,预后不良,甚至死亡[1]。食管炎并发食管破裂者极其罕见,我院收治1例食管炎并发食管破裂、感染性休克的患者,现报告如下。

Zhongguo shiyan zhenduanxue, 2011 目的提高对于原发性食管恶性黑色素瘤影像的认识。方法回顾性分析4例经手术病理证实的原发性食管恶性黑色素瘤患者的X线及CT影像资料,并复习相关国内外文献。结果 4例患者术前均行上部胃肠道口服钡餐造影及多层螺旋CT检查。肿瘤均为单发,2例肿瘤位于食管下段,2例位于食管中下段。病变均突向腔内,2例呈结节样,2例为不规则肿块。4例中1例螺旋CT证实有食管旁淋巴结增大。4例中1例术前考虑为原发性食管恶性黑色素瘤,3例考虑为食管癌。结论原发性食管恶性黑色素影像表现缺乏特异性,当食管中下段发现肿瘤且梗阻不明显时 ...

食管黏膜脱落细胞DNA倍体联合血清标志物检测在食管癌诊断中的价值
Zhongguo shiyan zhenduanxue, 2016 目的探讨血清肿瘤标志物神经元特异性烯醇化酶（NSE）、癌胚抗原（CEA）联合食管黏膜脱落细胞DNA倍体在食管癌诊断中的应用价值。方法选取我院收治的经胃镜诊断为食管病变患者128例,其中64为食管癌患者,64例为食管良性病变患者,使用罗氏电化学发光免疫系统检测其血清NSE、CEA水平,采用ICM检测DNA倍体水平,分析其特异性及敏感性。结果 64例食管癌患者中有45例DNA倍体为阳性,64例食管良性病变患者中,3例DNA倍体异常,食管癌组患者的NSE、CEA水平均明显高于良性病变组,组间比较有明显差异 ...

Psychometric framework for coexistence with large carnivores
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...
