1 192例乳腺癌患者癌因性疲乏的调查及影响因素分析

目的了解乳腺癌患者癌因性疲乏（cancer-related fatigue， CRF）现状，并分析其影响因素。方法采用横断面调查方法，向乳腺癌患者发放调查问卷，按照IDC-10诊断标准判断是否存在CRF，根据Piper疲乏量表中文修订版（Revised Piper Fatigue Scale, RPFS）得分评价疲乏程度，调查乳腺癌患者CRF的发生情况，并分析其影响因素。结果1 192例患者完成了全部调查问卷，乳腺癌患者发生CRF为668例（占56.04%）；以轻、中度疲乏为主，分别占23.95%、55.24%，其中感觉维度得分最高。单因素分析结果显示，文化程度、乳腺癌病程、肿瘤分期、化疗周期、疼痛、上肢水肿、白细胞减少、恶心呕吐、贫血、潮热盗汗、失眠与乳腺癌患者CRF的发生有关（P＜0.05）；多因素Logistic回归分析显示，乳腺癌肿瘤分期、疼痛、白细胞减少、恶心呕吐、潮热盗汗、失眠是CRF发生的危险因素（P＜0.05），病程是其保护因素（P＜0.05）。CRF认知调查显示，乳腺癌患者对CRF认知度低，医护人员对其宣教度低。结论乳腺癌患者发生CRF较为普遍，以轻、中度疲乏为主；乳腺癌肿瘤分期、疼痛、白细胞减少、恶心呕吐、潮热盗汗、失眠是影响患者CRF的危险因素；乳腺癌患者对CRF认知度低。

Art therapy for anxiety,depression, and fatigue in females with breast cancer: A systematic review

This systematic review employed a meta-analysis to examine the effectiveness of art therapy for treating anxiety, depression, and fatigue in female patients with breast cancer, the most prevalent cancer and the most common cause of cancer-related mortality among women worldwide. The review included nine original studies and analyzed data from a total of 754 patients. Data extraction and quality assessment were conducted by two independent reviewers. In total, 1,466 articles were retrieved. We excluded studies in which the participant, interventions, and study design did not satisfy the inclusion criteria, leaving nine articles for analysis, The Cochrane risk of bias assessment tools were used for quality evaluation. The analysis revealed a significant difference in treatment outcomes between patients who received art therapy and those who did not (SMD?=?–0.48, 95%CI [–0.75, –0.21, p?=?0.0005]). The review provides initial evidence to suggest that art therapy benefits female breast cancer patients with respect to the treatment of anxiety, depression, and fatigue. However, additional and better-quality studies must be conducted, particularly with larger sample sizes, greater specificity of the design of trials and interventions, and a longer follow-up duration.     

散聚汤加味对宫颈癌术后放化疗患者的癌因性疲乏和免疫功能的改善研究

[目的]探讨散聚汤加味改善宫颈癌术后放化疗患者的癌因性疲乏和免疫功能的疗效。[方法]筛选在洛阳解放军534医院行宫颈癌手术后患者共82例作为研究对象,按随机数字表法随机分为对照组和观察组各41例。对照组给予同步放疗+TP化疗方案[紫杉醇(TAX)+顺铂(DDP)]。观察组在对照组基础上给予散聚汤加味治疗,每日1剂,每日2次,连续服用12周。比较两组患者癌因性疲乏评分、毒性反应、T淋巴细胞亚群水平以及血清免疫球蛋白(IgA、IgG、IgM)水平。[结果]治疗12周后,观察组患者的癌因性疲乏(情绪、感觉、行为、认知)评分显著低于对照组(P0.01);观察组患者的消化道反应、膀胱刺激发生率明显少于对照组(P0.05);治疗12周后,观察组患者CD3+、CD3+CD4+以及IgA、IgG、IgM水平显著高于对照组,CD3+CD8+明显低于对照组(P0.01)。[结论]散聚汤加味能改善宫颈癌术后放化疗患者的癌因性疲乏,增强免疫功能,且可降低毒副反应。     

Effect of Curvature Location on Fatigue Resistance of Five Nickel-titanium Files Determined at Body Temperature

IntroductionThe purpose of this study was to evaluate the effect of 5 different curvature locations on the fatigue resistance of thermomechanically treated nickel-titanium (NiTi) files and superelastic NiTi files at body temperature and to document the corresponding phase transformations.MethodsEndoSequence (ES; Brasseler USA, Savannah, GA), EndoSequence CM (ESCM, Brasseler USA), K3 (SybronEndo, Orange, CA), K3XF (SybronEndo), and Vortex Blue (VB; Dentsply Tulsa Dental Specialties, Tulsa, OK) NiTi files (size 25/.04) were subjected to fatigue tests inside customized artificial canals containing a curvature of 60° and a 3-mm radius. There were 5 different canals based on the location of initial curvature; these included groups in which the distance between the canal orifice and the location of the curvature (DOC) was 5, 6, 8, 10, and 11 mm. The model canal was immersed in water at 37°C ± 1°C. The number of cycles to failure (N_f) was recorded, and the fracture surface of the fragments was examined by scanning electron microscopy. Two unused files of each brand were examined by differential scanning calorimetry.ResultsThe N_f was highest in the 10-mm and 11-mm DOC groups and lowest with the 5-mm and 6-mm DOC groups (P < .05). ESCM files had the highest fatigue resistance followed by the VB, K3XF, K3, and ES files (P < .05). ESCM files had the highest N_f (P < .05), and ES and K3 files had the lowest N_f (P < .05) depending on the curvature location. Two endothermic peaks were observed on the heating curve of the heat-treated files (ESCM, K3XF, and VB).ConclusionsThe location of the canal curvature had a significant effect on the fatigue resistance of both heat-treated and superelastic NiTi files. The fatigue life of files in the coronal curve was quite short.
