A comparative study of SPECT/CT fusion imaging and CT in infiltrated mandible by gingival carcinoma

Objective： The aim of the study was to evaluate the clinical value of ^99mTc-methylene diphosphonic acid （MDP） SPECT/CT fusion imaging and CT scanning in diagnosis of infiltrated mandible by gingival carcinoma. Methods： 18 cases of gingival carcinoma were processed infiltrated mandible by ^99mTc-MDP SPECT/CT fusion image and CT, and their scanning results compared with pathology findings. Results： Eleven of 13 cases with well-differentiated squamous cell carcinoma showed positive images, one of 11 cases was false positive images by pathology findings, and 10 cases were exhibited infiltrated mandibles; 5 cases with moderately differentiated and poorly differentiated squamous call carcinoma showed positive images, pathology showed carcinoma call had infiltrated cavum ossis of mandible. Five of 18 cases were positive images by CT. Conclusion： ^99mTc-MDP SPECT/CT fusion imaging is a useful method in diagnosis of infiltrated mandible by gingival carcinoma.

文化逆势情境下的中国企业跨文化整合模式研究

中国企业对发达国家企业的海外并购呈现出不同的特点,对文化整合产生了较大的影响。文章首先分析了以往跨文化整合研究中存在的问题,提出中国企业对发达国家企业的并购中表现出的文化逆势这一情境,以及该情境所带来的整合困境。面对这一困境,文章提出了前整合阶段的文化提升,并购后对民族文化的主动适应及对企业文化的渗透—融合这一整合模式,这对文化提升和渗透—融合以及普世商业伦理等方面都提供了明确的方向。
