Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a disorder that may lead to functional impairment, including gait abnormalities. Our aim was to analyze gait characteristics in patients with CIDP compared to healthy controls (HC). Moreover, we sought to determine changes of gait parameters after six-month follow-up period. Twenty-four patients with CIDP and 24 HCs performed basic walking task, dual-motor task, dual-mental task, and combined task using the same GAITRite system. Lower limb MRC-SS and lower limb INCAT disability score were assessed. Fourteen patients were retested after six months. Majority of gait parameters showed significant differences in all experimental conditions when compared between CIDP and HCs. The most consistent findings in CIDP were shorter stride length (SL), prolonged cycle time (CT) and double support time (DS), as well as increased variation of SL and of swing time (ST) (p < 0.05). During follow-up, INCAT improved in nine (64.3%) of 14 patients and MRC-SS improved in eight (57.1%) patients. Six-month changes of CT and its variation during combined task significantly differentiated patients with improved vs. non-improved INCAT (p < 0.05). In conclusion, patients with CIDP had slower gait with prolonged DS and with shorter SL compared to HCs. Increased variation of SL and of ST in CIDP may suggest a potential risk for instability and falls. Shorter CT duration and less CT variation during time correlated well with improvement in disability. 相似文献

Multiple sclerosis (MS) is a chronic inflammatory disease and the most common neurodegenerative status. MicroRNAs play an important role in macrophage response to inflammatory processes, and alterations in miRNA levels trigger the inactivation of specific T lymphocytes. As a result, these factors can lead to autoimmune diseases such as MS. Therefore, to determine the role of MicroRNA-146a and MicroRNA-155 in MS patients, their expression levels in serum of MS patients were compared with healthy controls.In this study, the expression levels of MicroRNA-146a and MicroRNA-155 in 30 serum samples of MS and healthy patients as a control group. MicroRNA extraction and cDNA synthesis was performed according manufacture protocols. The expression levels of MicroRNAs were evaluated by Real Time-PCR.MicroRNA-146a and MicroRNA-155 levels were increased in patients with MS compared to controls. The results demonstrated that EDSS score are increased with increasing level of MicroRNA-146a and MicroRNA-155. ROC curve analysis showed that the area under curve (AUC) was significant for MicroRNA-146a and MicroRNA-155.Increased expression levels of MicroRNA-146a and MicroRNA-155 may be associated with the pathogenesis of MS disease. If this study is conducted in a larger sample population and the above results can be used to identify patients or control patients who are under medical care. 相似文献

目的探讨血清趋化因子检测在肺癌早期诊断中的应用价值。方法采用回顾性总结研究方法,选择肺癌患者72例(肺癌组)、肺炎患者72例(肺炎组)与健康人72例(对照组),检测3组人群的白细胞计数,检测血清趋化因子MIP-3α、IL-8、Fractalkine水平,随访记录患者的预后,判断诊断价值。结果肺癌组与肺炎组的外周白细胞计数均显著低于对照组(P<0.05),但肺癌组与肺炎组对比差异无统计学意义(P>0.05)。肺癌组与肺炎组的血清MIP-3α、IL-8、Fractalkine水平都高于对照组(P<0.05),肺癌组高于肺炎组(P<0.05)。随访至2018年9月,肺癌组中患者死亡6例,存活66例,死亡率为8.3%。多因素logistic回归分析淋巴结转移、临床分期、组织学分化、MIP-3α、IL-8、Fractalkine为影响患者预后死亡的主要独立危险因素(P<0.05)。结论MIP-3α、IL-8、Fractalkine等趋化因子联合现有的肿瘤标志物,可用于诊断早期肺癌与预测预后。 相似文献

目的:探讨食管腺癌(esophageal adenocarcinoma,EAC)患者血清中脂联素与炎症细胞因子水平及肿瘤组织病理特点之间的相关性,分析脂联素是否通过调节食管组织炎症而参与抑制肿瘤的进展。方法:收集25例健康人、23例Barrett食管(Barrett's esophagus,BE)患者和18例EAC患者。登记临床病例资料;采集空腹静脉血,采用ELISA法检测血清中脂联素和TNF-α、IL-8、IL-6水平并分析其相关性;进行HE染色观察食管组织局部炎症情况。结果:健康对照组、BE组、EAC组三组间相比较发现,随着食管病变的加重,食管局部炎症细胞浸润越明显,同时检测到血清中TNF-α、IL-8、IL-6水平逐渐升高,相反血清脂联素水平逐渐降低;相关性分析结果显示血清炎症细胞因子水平与脂联素水平间存在着负相关关系。结论:EAC发病过程中,食管局部炎症反应逐渐加重,血清炎症细胞因子水平逐渐升高,而脂联素水平逐渐降低,两者之间存在着明显的负相关关系。由此可知,低脂联素血症可能与EAC发生和进展过程中持续存在的慢性炎症有关。 相似文献

BackgroundLong noncoding RNA urothelial cancer‐associated 1 (lnc‐UCA1) targets microRNA‐26a (miR‐26a) and microRNA‐195 (miR‐195) to participate in coronary heart disease (CHD) progression via regulation of vascular smooth muscle cell and microvascular endothelial cell viability and mobility. Therefore, this study set out to further explore the relationship between lnc‐UCA1 and miR‐26a and miR‐195, along with their roles in the management of patients with CHD.MethodsOne hundred and thirty‐six CHD patients and 70 age‐/gender‐matched controls were recruited in this case‐control study. Their peripheral blood mononuclear cell samples were collected for lnc‐UCA1, miR‐26a, and miR‐195 measurement. Furthermore, serum samples from CHD patients were obtained for inflammatory cytokines and cell adhesion molecules measurement. The Gensini score was used to evaluate the stenosis severity in CHD patients.ResultsLnc‐UCA1 expression tend to be increased, while miR‐26a and miR‐195 expressions were reduced in patients with CHD compared to that of controls (all p < 0.001). In CHD patients, lnc‐UCA1 was negatively correlated with miR‐26a (p < 0.001) and miR‐195 (p = 0.014). Besides, lnc‐UCA1 was positively correlated with Gensini score (p < 0.001), total cholesterol (p = 0.019), low‐density lipoprotein cholesterol (p = 0.002), and C‐reactive protein (p < 0.001), while miR‐26a (p < 0.001) and miR‐195 (p = 0.002) were negatively correlated with Gensini score. What''s more, lnc‐UCA1 was positively correlated with tumor necrosis factor (TNF)‐α (p = 0.004), interleukin (IL)‐1β (p = 0.041), vascular cell adhesion molecule‐1 (VCAM‐1) (p = 0.010), and intercellular adhesion molecule‐1 (ICAM‐1) (p < 0.001). While miR‐26a was negatively correlated with some of the individual inflammatory cytokines and cell adhesion molecules.ConclusionLnc‐UCA1, miR‐26a, and miR‐195 may serve as potential biomarkers for CHD management. 相似文献
