HCIF/胶原复合物组织结构的显微观察

目的采用组织学方法,观察HCIF/胶原蛋白复合物的生物学特性。方法取HCIF、HCIF/胶原蛋白复合物及未经任何处理的牛骨（作对照）三个样品,行组织学切片,对其进行组织学观察和研究。结果HCIF试样与对照试样相比,镜下骨板、骨单位组织结构无明显改变,而骨基质伊红染色明显变浅;而HCIF/胶原蛋白复合物的骨基质伊红染色与对照试样相近。结论理化方法能破坏牛骨组织中的胶原基质,复合物能恢复牛骨组织中的胶原基质。     

PBL+LBL双轨教学法在机能实验学教学中应用的体会

在机能实验学教学中,尝试将传统医学实验教学方法与以问题为基础的新型教学法进行有机结合。实践证明两种方法的结合起到了取长补短的作用,不仅可以充分进行系统知识的传授,而且更有效地培养学生分析问题的能力、解决问题的能力和终生学习能力,进一步培养学生的团队合作精神。双轨教学法的应用明显提高机能实验学教学质量,得到了学生的好评和教师的认可。     

阴阳平衡与氧化还原调节＊

传统中医药与现代生命科学有着不同的理论基础，但两者对生命健康的认识存在许多相通之处。随着现代生命科学的不断发展，中医与现代生命科学的碰撞和对话已成为人们日益关注的焦点。人们在深入到细胞乃至分子层次认识各种生命现象的同时，在现代生命科学的带动下，对中医药的认识也得到不少新的启发。本文通过对中医阴阳平衡理论与细胞氧化还原平衡之间的相关性，探讨阴阳平衡理论的微观表现，以期为中医药现代化研究提供新的思路。

Intravenous leiomyomatosis: diagnosis and follow-up with multislice computed tomography

Intravenous leiomyomatosis is a rare disease, which appears histologically benign but is clinically aggressive. It is characterized by the intraluminal growth of leiomyomas in the intrauterine and systemic veins. Intravenous leiomyomatosis was reported to have originated in the uterus and extended into the right ventricle via the inferior vena cava (IVC). In these circumstances, it is fatal. Multislice compute tomography (MSCT) allows an early and accurate preoperative diagnosis, resulting in a higher rate of surgical resection and improved survival. The authors present 3 cases of intravenous leiomyomatosis with a history of uterine leiomyoma and hysterectomy. The lesions were found to have extended through the IVC into the right cardiac cavities and were confirmed to be intravenous leiomyomatosis by surgery.

Langerhans cell histiocytosis of bone in children: a clinicopathologic study of 108 cases

Background  

Langerhans cell histiocytosis (LCH) is a rare disease that is characterized by abnormal proliferation of pathological Langerhans cells (LCs). In this study, a total of 108 pediatric patients with LCH of bone were evaluated retrospectively for illustrating the clinicopathologic features of this disease, with a goal of improving the diagnosis, treatment, and prognosis.     

护士安全感对离职意愿的影响研

目的 探讨护士安全感与离职意愿之间的关系,为降低离职意愿、减少护士流失提供参考。方法 采用一般资料调查表、医务人员安全感量表、离职意愿量表对广东省29所医院的2 480名护士进行调查。结果 护士安全感总分为（79.62±19.60）分,离职意愿总分为（14.13±4.27）分,安全感与离职意愿呈负相关（P＜0.05）。分层回归分析结果显示,安全感可解释护士离职意愿14.7%的变异。结论 护士安全感水平越高,离职意愿越低,管理者可通过提升安全感降低护士离职意愿,维持护理队伍的稳定。     

Foreign body granuloma in the tongue differentiated from tongue cancer: A case report

BACKGROUNDEmbedded foreign bodies in the tongue are rarely seen in clinical settings. An untreated foreign body can cause a granuloma which often presents as an enlarged tongue mass. However, if foreign body ingestion status is unknown, physical examination and magnetic resonance imaging (MRI) tend to lead to suspicion of tongue cancer, especially in older patients. Thus, differential diagnosis of an enlarged tongue mass is important, especially because it is closely related to the choice of treatment method.CASE SUMMARYA 61-year-old woman was admitted to the hospital with pain and noticeable swelling in the tongue that had persisted for over 1 mo. She had no previous medical history. MRI revealed abnormal signal intensities that were indicative of a neoplasm. Thus, the oral surgeon and radiologist arrived at a primary diagnosis of tongue cancer. The patient visited the Ear Nose and Throat Department for further consultation and underwent an ultrasound examination of the tongue. The ultrasonography was consistent with a linear hyperechoic foreign body which was indicative of an embedded foreign body (bone) in the tongue, even though the patient denied any history of foreign body ingestion. Complete surgical enucleation of the lesion was conducted. The mass which included a fish bone was completely removed. The post-operative pathological examination confirmed that the mass was a granuloma containing collagen fibers, macrophages and chronic inflammatory cells. The patient recovered without complications over a 2 mo follow-up period.CONCLUSIONWe report a rare case of foreign body granuloma in the tongue that was primarily diagnosed as tongue cancer. The MRI and ultrasound examinations revealed a piece of bone in the left lateral aspect of the tongue. The granuloma, which contained a fish bone, was completely removed via surgery and confirmed via biopsy. Differential diagnosis of the enlarged tongue mass was critical to the selection of treatment method.
