血清丙种球蛋白Fc段唾液酸化水平及其临床意义

目的 建立丙种球蛋白(IgG)Fc段唾液酸化水平的检测方法,并探讨血清IgG-Fc段唾液酸化在系统性红斑狼疮(SEE)尤其是神经精神狼疮(NPSLE)中的临床意义.方法 采用基于亲和素的夹心法酶联免疫吸附试验(ELISA)检测75例SLE患者(进一步分为NPSLE和非NPSLE 2个亚组),30例类风湿关节炎(RA)患者,32例幼年特发性关节炎(JIA)患者和41名健康对照者血清唾液酸化IgG,同时记录SLE患者临床资料,计算SLE疾病活动指数(SLEDAI),分析唾液酸化IgG的临床意义.结果 唾液酸化的IgG在RA组为(0.82±1.81)mg/mg/ml,JIA组为(0.69±1.30)mg/ml,健康对照组为(0.64±1.09)mg/ml,组间差异无统计学意义(P=0.82),SLE组为(0.12±0.17)mg/ml,唾液酸化水平明显降低(P<0.01),其中NPSLE组为(0.03±0.03)mg/ml,较其他组显著下降(P<0.01);健康对照组IgG唾液酸化的程度为(4.64±5.90)%,显著高于非NPSLE组的(1.88±2.16)%和NPSLE组的(0.29±0.47)%(P<0.01).唾液酸化的IgG占总IgG的百分数与SLEDAI负相关(r=-0.43,P<0.01).结论 SLE患者的IgG-Fc段唾液酸化水平较健康人群显著降低,且与狼疮活动度负相关,尤其在神经精神累及患者的IgG-Fc段唾液酸化水平下降尤为突出,提示唾液酸化的IgG有可能成为一种新的生物治疗手段.     

系统性红斑狼疮合并肠假性梗阻12例临床分析

目的 分析系统性红斑狼疮(SLE)合并肠假性梗阻病人的临床表现及实验室检查，提高对SLE合并肠梗阻的认识。方法对12例SLE合并肠梗阻的病人进行回顾性分析，收集整理其临床资料及有关实验室检查，分析其发病情况、临床累及脏器、实验室检查、病程、治疗及预后等特点。结果发病年龄2l～56岁，平均36岁，平均病程31个月。死亡5例。以肠梗阻为首发症状者2例。有肾脏累及者9例，血液系统累及者6例，中枢神经系统累及者2例，循环系统累及者8例。其他：胃肠出血4例，腹水4例。2例以肠梗阻为首发症状者入院前分别误诊为溃疡性结肠炎和肠炎。2例曾行剖腹探查并部分小肠切除术，病理报告均提示肠道血管炎。结论SLE合并肠梗阻患者病情较重，常伴有其他脏器累及，病死率较高。以肠梗阻为首发症状的SLE患者易被误诊。有肠梗阻症状并有其他脏器累及者应排除有无SLE可能。肠道血管炎是引起肠梗阻的主要原因。     

寡腺苷酸合成酶家族基因的定表达与系统性红斑狼疮的临床特征

目的探讨系统性红斑狼疮(SLE)患者外周血单个核细胞(PBMC)中寡腺苷酸合成酶(OAS)1、OAS2和OASLmRNA的实时定量表达水平与SLE疾病特异性和病情活动度的相关性。方法收集144例SLE患者、27例非SLE患者与59名正常对照人群的临床资料,取外周血抽取总RNA并反转录成cDNA,运用sybrgreendyeⅠ实时定量聚合酶链反应(PCR)法在ABIPRISM7900H基因测序仪上检测患者组和对照组的OAS1、OAS2的OASLmRNA表达水平的差异,并与病情活动度进行分组比较,分析其意义。结果①SLE患者的总体OAS1mRNA定量表达水平显著高于非SLE对照组和正常对照组,差异有非常显著性(P=0郾016,P=0郾000);OAS2mRNAP定量表达水平高于正常对照组(P=0郾015);而OASLmRNA定量表达水平与非SLE对照组和正常组之间差异无显著性(P=0郾698,P=0郾396)。②SLE活动组的OAS1和OASLmRNA定量表达水平均显著高于SLE非活动组,差异有非常显著性(P=0郾011,P=0郾001)。但SLE活动组的OAS2表达水平与SLE非活动组之间差异无显著性(P=0郾109)。③SLE患者组的OAS2和OASLmRNA定量表达水平与SLEDAI积分呈正相关性(P=0郾001,P=0郾006)。④SLE患者的肾、肺、脑、血液等器官的有无受累与OAS1、OAS2和OASLmRNA表达水平无相关性。⑤SLE患者组和正常对照组组内的OAS1、OAS2和OASL表达水平     

重症监护病房系统性红斑狼疮患者预后因素分析

Objective To analyze the outcomes and prognostic factors associated with the death of systemic lupus erythematosus (SLE) patients admitted to the intensive care unit (ICU). Methods During June 1996 to June 2007, all SLE patients admitted to the ICU were included. Patients were excluded if the diagnosis of SLE was established at or after ICU admission. A multivariate logistic regression model was applied using variables that were associated with death in the univariate analysis. Results A total of 101 patients meeting the criteria were included. The mortality rate was 48.6%. The most common causes of admission was lung disorder with acute respiratory distress syndrome (ARDS). Multivariate logistic regression analysis suggested that SLICC/ACR DI>7.7 (OR=6.87), APACHE Ⅲ≥21 (OR=29.8), lung disorders with ARDS (OR =55.81 ), septic shock (OR =32.22 ), intracranial haemorrhage (OR =57.35 ), hypocytopenia (OR = 5.89), mean equivalent prednisone dose>25 mg/d (OR=7.65) and prolonged tracheal intubation (OR=5.98) were signi-ficantly associated with death. Whereas sex, age, SLEDAI >27, gastrointestinal bleeding, the cumulative dosage of CTX higher than 1.0 g, pulse intravenous methylprednisolone therapy were not associated with death. Conclusion The mortality rate of critically ill SLE patients in ICU is very high. SLICC/ACR DI> 7.7, APACHE Ⅲ≥21, lung disorders with ARDS, septic shock, intracraniai haemorrhage, average prednisone equivalent dosage higher than 25mg/d and prolonged tracheal intubation (longer than 4 days) are negative prognostic factors in SLE patients admitted to the ICU.     

超声斑点追踪技术对系统性红斑狼疮患者局部心肌收缩功能的评价

目的 应用超声斑点追踪技术(STI)评价系统性红斑狼疮(SLE)患者局部心肌收缩功能.方法 ①SLE组36例,健康对照组24名,分别记录并存储每位被检者心尖位左心室3个长轴切面高帧频二维动态图像,应用自动功能成像软件(AFI)检测左心室壁18节段收缩期峰值应变(S),记录并比较各参数测值.②在对照组中随机取20名被检者,双盲条件下,由同一观察者不同时间及2名观察者分别测量每位被检查者心肌收缩期峰值应变值,2组问计量资料比较采用非配对t检验,并利用Pearson相关分析法分析其相关性.结果 对照组左心室各壁S值自基底段向心尖段逐渐增加,心尖段与基底段、中间段差异有统计学意义(P＜0.05),不同室壁对应节段间差异无统计学意义(P＞0.05);同一室壁各节段心肌收缩期峰值应变达峰时间基本一致.SLE组除前间隔和前壁外各室壁S值自基底段向心尖段逐渐增加[(-18.7+4.2)%,(-16.3±9.4)%,(-18.1±10.5)%与(-19.0±9.0)%,(-18.6±7.9)%,(-17.7±1.4)%],心尖段与基底段、中间段差异均无统计学意义(P＞0.05);SLE组各室壁各节段S值明显低于对照组,差异均有统计学意义(P＜0.05);SLE组同一室壁各节段心肌收缩期峰值应变达峰时间一致性差.同一观察者不同时间及2名观察者问对心肌收缩期峰值应变值的测量相关性良好(P＜0.01).结论 STI技术发现SLE患者与健康对照组差异有统计学意义,SLE患者心肌损害表现为左室局部心肌收缩期峰值应变减低.

Abstract：

Objective To assess the vaIue of speckle tracking imaging (STI) in quantifying the regional myocardial strain in systemic lupus erythematosus (SLE) group.Methods ① Sixty subjects were divided into SLE group and normal group.High frame rate two-dimensional images were recorded from the apical two-chamber view,long-axis view and four-chamber view of the left ventricle (LV).Peak systolic strain of each view of 18 segments were measured by automated functional imaging (AFI) software of 2-DSE.All parameters were compared between the two groups.② Twenty cases were randomly taken from the normal group.The same observer at different times and two observers measure the strain of left ventricular respectively.The results of the measurement between the two groups were compared with unpaired t test and its relevance was analyzed using Pearson's correlation analysis.ResultsLeft ventricular two-dimensional longitudinal strain gradually increased from the base to apex in the normal group.There were statistically differences between the apical segments and the basal,middle segments of every left ventricular wall (P＜0.05).The same wall segment time to peak myocardial systolic peak strain was consistent.Left ventricular two-dimensional longitudinal strain gradually increased from the base to apex in the SLE group,except for the anterio-septal and anterior wall [ (-18.7±4.2)％,(-16.3±9.4)％,(-18.1±10.5)％ vs (-19.0±9.0)％,(-18.6±7.9)％,(-17.7±1.4)％ ].There was no statistically significant difference between the apical segments and the basal,middle segments of every left ventricular wall(P＞0.05).All parameters of S were significantly higher in the normal group than those of the SLE group.The difference was statistically signoficant (P＜0.05).The time to peak systolic peak strain of every segments was not consistent.The results from the same observer at different times and peak systolic myocardial strain measurements by the two observers were correlated well(P＜0.01).Conclusion The myocardial function assessment by STI technology in the SLE patients is significantly different from that of the normal control:SLE patients with left ventricular myocardial damage can be manifested as reduced regional myocardial systolic peak strain.     

左旋门冬酰胺酶对急性淋巴细胞白血病患者凝血功能的影响

目的探讨左旋门冬酰胺酶对急性淋巴细胞白血病患者凝血功能的影响。方法回顾性分析2013年1月~2017年1月我院血液科收治的100例急性淋巴细胞白血病患者的一般资料。所有患者在化疗前均未接受过任何抗凝治疗。入院后所有患者均接受常规治疗,即使用长春新碱+柔红毒素+波尼松诱导治疗,治疗后予VDLP方案化疗。同时加用左旋门冬酰胺酶8000 U/m2,静脉注射,隔日注射1次。治疗3个月后对其临床疗效进行评价,并对治疗期间的不良反应进行观察,同时比较患者治疗前及治疗后第1天、第7天的凝血功能各项指标的变化情况。结果 100例患者中,完全缓解22例、部分缓解40例、病情稳定26例、病情进展12例,总有效率达62%(62/100)。100例患者治疗期间,10例发生过敏、白细胞计数下降9例、8例出现胃肠道反应包括恶心、呕吐。治疗后第1天,100例患者的PT、APTT、TT水平较治疗前比较显著升高,差异存在显著性(P0.05或P0.01)。但患者的FIB水平与治疗前比较显著降低,差异存在显著性(P0.05)。治疗后1周,所有患者的PT、APTT、TT水平较治疗前比较,未见明显差异(P0.05),而FIB水平虽然较治疗后第1天有所升高,但差异不显著,但与治疗前水平比较显著降低,差异存在显著性(P0.05)。结论左旋门冬酰胺酶治疗急性淋巴细胞白血病疗效确切,安全性好,但易产生凝血功能异常等不良反应,因此,应用左旋门冬酰胺酶临床治疗急性淋巴细胞白血病中应动态监测患者的的凝血功能,才能积极纠正凝血功能障碍,必要时应停药。     

综合性康复干预对非瓣膜性房颤患者抗凝治疗依从性及生活质量的影响

目的探讨综合性康复干预对非瓣膜性房颤(NVAF)患者抗凝治疗依从性及生活质量的影响。方法选取2015年1月～2017年1月期间就诊的NVAF患者共100例,随机分为观察组与对照组,两组患者均予以常规的药物治疗与健康指导,观察组患者在此治疗的基础上加用综合性康复干预,疗程6个月。观察两组患者抗凝治疗的依从性,并在干预前后检测两组的生活质量和疗效的差异。结果干预6个月后,两组患者治疗依从性Morisky评分均较干预前明显改善(P0.05或P0.01),且观察组改善幅度较对照组更显著(P0.05);干预6个月后,两组生活质量SF-36评分均较干预前显著上升(P0.05或P0.01),且观察组上升幅度较对照组更显著(P0.05)。结论综合性康复干预用于NVAF患者不仅能有效提高患者抗凝治疗的依从性,而且改善患者的生活质量。
