目的 探讨原发性干燥综合征周围神经病变的发生与干燥综合征A型/B型抗体（抗SSA/SSB抗体）的关系。 方法 纳入2009年1月－2011年12月期间门诊及住院收治的原发性干燥综合征患者88例。所有患者均接受神经系统检查，采用蛋白质印迹法检测抗SSA抗体和抗SSB抗体，利用全自动化学发光仪检测血清维生素B12水平。 结果 88例原发性干燥综合征患者中有27例（30.7%）存在周围神经病变。有或无周围神经病变的患者在年龄、性别、病程等一般情况方面无明显不同。有周围神经病变和无周围神经病变的原发性干燥综合征患者抗SSA抗体阳性率分别为70.4%（19/27）、70.5%（43/61），差异无统计学意义（χ2=0.000，P=0.991）；抗SSA/SSB抗体双阳性率分别为63.0%（17/27）、14.8%（9/61），差异有统计学意义（χ2=17.416，P=0.000）；血清维生素B12水平分别为（390 ± 55）、（410 ± 86）pg/dL，差异无统计学意义（t=0.908，P=0.370）。 结论 周围神经病变在原发性干燥综合征患者中较常见，且周围神经病变的发生多伴随血清抗SSA/SSB抗体阳性。
目的 观察白芍总苷治疗原发性干燥综合征的疗效及不良反应。 方法 收集2008年1月－2012年1月诊断的原发性干燥综合征患者48例，使其口服白芍总苷0.3～0.6 g，3次/d，疗程6个月，对比治疗前后患者的临床症状及唾液腺功能（唾液腺核素显像定量分析）改善情况、泪液分泌试验（Schirmer试验）、血沉、C反应蛋白、血清γ球蛋白（采用琼脂糖凝胶电泳法）的改善情况，并记录可能的不良反应。 结果 经过6个月的治疗，患者的临床症状、血沉、C反应蛋白、血清γ球蛋白等方面情况有所改善，差异有统计学意义（P＜0.05）。但唾液腺功能、Schirmer试验改善不明显，差异无统计学意义（P＞0.05）。 结论 白芍总苷在改善原发性干燥综合征临床症状及实验室指标疗效好，不良反应少，但在改善唾液腺功能及泪腺功能疗效欠佳。
ObjectiveTo analyze the correlation of thrombopoietin (TPO) and anti-TPO antibody with thrombocytopenia in patients with primary Sjögren syndrome (PSS). MethodsWe included in our study 40 PSS patients with thrombocytopenia (group A), 22 PSS patients who once had thrombocytopenia and returned to normal (group B), 40 PSS patients with normal platelet counts (group C) and 40 healthy controls (group D) between September 2013 and October 2014. Anti-TPO antibody was detected by indirect enzyme-linked immunosorbent assay (ELISA), and serum TPO levels were measured by ELISA. We analyzed the relationship between the assay results and the clinical manifestations and parameters. ResultsThe serum TPO levels in groups A, B, and C were (129.74±17.47) , (330.23±18.07) and (364.19±12.25) pg/mL, respectively, and they were significantly higher than that in group D [(54.04±10.71) pg/mL] (P ＜ 0.05) . The serum level of TPO was positively correlated with CRP and IgA (rs=0.224, P=0.039; rs=0.239, P=0.033) , and was negatively correlated with C4 level (rs=?0.220, P=0.041) , but it was not significantly correlated with platelet count, erythrocyte sedimentation rate, the level of antiphospholipid antibodies and the titer of antinuclear antibodies (P ＞ 0.05) . The positive rate of PSS patients was 20.59% (21/102) and the rate in groups A, B, and C was respectively 17.5% (7/40) , 22.72% (5/22) , and 22.5% (9/40) . There was no statistically significant difference between the positive and negative groups in various clinical indexes (P ＞ 0.05) . ConclusionAntiTPO antibody may not be the main mechanism of thrombocytopenia in PSS patients, and there is a certain correlation between TPO and inflammatory factors.
Objective To detect the expression levels of ERdj5 and XBP1 in the salivary glands of patients with primary Sjögren syndrome (pSS), and analyze the correlation of the expression levels of ERdj5 and XBP1 with salivary gland damage and oral symptoms to explore their significance in the pathogenesis of pSS. Methods A total of 60 pSS patients in the departments of rheumatology and immunology of Xi’an Honghui Hospital and Qinghai Provincial People’s Hospital between January 2020 and June 2021were randomly selected as the case group, and 20 healthy participants in Qinghai Provincial People’s Hospital in the same period were randomly selected as the control group. The mRNA and protein expression levels of ERdj5 and XBP1 in salivary gland tissues were detected by reverse transcription-polymerase chain reaction and Western blot, respectively, and their correlation with histopathology, salivary flow rate, dry mouth degree, and clinical test indicators were analyzed. Results The mRNA and protein expression levels of ERdj5 and XBP1 in the case group were higher than those in the control group (P<0.001). The ERdj5 mRNA expression was positively correlated with the XBP1 mRNA expression in the case group (rs=0.936, P<0.001). The expression levels of ERdj5 mRNA and XBP1 mRNA in the case group were positively correlated with the pathological grade of labial gland (rs=0.344, P<0.001; rs=0.401, P<0.001), dry mouth degree (rs=0.683, P<0.001; rs=0.730, P<0.001), anti-Ro/SSA antibody (rs=0.363, P<0.001; rs=0.350, P<0.001), anti-La/SSB antibody (rs=0.506, P<0.001; rs=0.471, P<0.001), and European League Against Rheumatism Sjogren’s Syndrome Disease Activity Index (rs=0.782, P<0.001; rs=0.865, P<0.001), and were negatively correlated with salivary flow rate (rs=–0.445, P<0.001; rs=–0.526, P<0.001). Conclusion The expression levels of ERdj5 and XBP1 in salivary glands are increased in pSS patients, and they are related to disease activity, anti-Ro/SSA and anti-La/SSB autoantibodies, damage degree of salivary gland and oral symptoms of patients.
