朗格汉斯细胞组织细胞增生症 (Langerhans cell histiocytosis,LCH) 是一种由骨髓细胞肿瘤性增殖引起的罕见疾病，多见于儿童。LCH临床表现多样，以骨骼受累最常见。该文报道了一例儿童颅眶沟通LCH，影像学检查结果提示患儿右侧眉弓处类圆形穿凿样骨质破坏，通过手术切除病灶，送组织病理学检查明确诊断，同时选择通过3D打印聚醚醚酮(polyetheretherketone,PEEK)材料修补颅眶缺损部位，PEEK材料匹配度高、安全性好，改善患儿预后，提升患儿生存质量。
Langerhans cell histiocyte (LCH) is a rare disease caused by the tumor-like proliferation of bone marrow cells, which is mostly seen in children. Its clinical manifestations can be diverse, in which the skeletal system is most involved. This paper reports a case of LCH in cranio-orbital communication of a child. The imaging results suggest that there is a round chisel damage at the patient’s right brow ridge. In terms of definitive diagnosis and treatment, this patient underwent surgical resection and histopathological examination. 3D-printed polyether-ether-ketone (PEEK) material was selected to repair the cranio-orbital defect. The material can achieve better biocompatibility, while 3D-printing technique allows higher matching degree, both help to improve the prognosis and quality of life of the patient.
干眼为最常见的眼表疾病之一，以泪膜稳态丢失及伴随眼部症状为特征。干眼的治疗以消除病因、缓解症状和保护视功能为目标，而其中的心理护理、眼睑物理治疗、健康宣教和院外管理尤为重要。优质的整体护理方案有助于干眼患者的治疗。本团队在参考干眼诊疗共识的基础上，结合自身护理经验，为干眼患者制定了个性化、涵盖全面的整体护理方案并运用。
Dry eye is one of the most common ocular surface diseases, characterized by a loss homeostasis of tear film,and accompanied by ocular symptoms. The treatment of dry eye aims to eliminate the cause of disease, relieve symptoms, and protect the visual function, among which psychological care, physical treatment of eyelid, health education and management outside the hospital are particularly important. High quality holistic nursing plan is helpful to the treatment of dry eye patients. Based on the consensus of the diagnosis and treatmen of dry eye,combined with our nursing experience, our team has developed and applied a personalized and comprehensive holistic nursing plan for dry eye patients.
干眼是以泪膜稳态丢失及伴随眼部不适症状为特征的最常见眼表疾病，泪膜不稳定、泪液高渗透性、眼表炎症及感觉神经异常为其主要病因。地夸磷索钠是一种P2Y2受体激动剂，能刺激黏蛋白及泪液分泌，其独特的作用机制为干眼的治疗开辟了新的方向，本文就地夸磷索钠近年的临床及基础研究进展作一综述。
Dry eye is one of the most common ocular surface diseases. It is characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and tear hyperosmolarity, ocular surface inflammation, and neurosensory abnormalities play major etiological roles. Diquafosol tetrasodium is a purinergic P2Y2 receptor agonist that promotes mucin and aqueous tear secretion. The unique pharmacological mechanism of diquafosol tetrasodium opens up a new direction for the medical therapies of dry eye. This article reviews the clinical therapeutic effect and research progress of diquafosol tetrasodium for the past few years.
