【摘要】 目的 探讨慢性丙型肝炎患者干扰素治疗前后血清自身抗体的合并状况。 方法 回顾性分析2005年2月-2008年2月66例慢性丙型肝炎患者应用干扰素治疗前后的检测结果，观察治疗前后自身抗体合并状况及与干扰素疗效的关系。 结果 ①66例慢性丙型肝炎患者中39例自身抗体阳性，阳性率59.1%（39/66），主要为ANA；②自身抗体的产生与年龄相关，而与性别、HCVRNA定量无关；③自身抗体阳性组干扰素应答率66.7% （26/39）明显高于阴性组40.7%（11/27），二者比较差异有统计学意义；④干扰素治疗后，自身抗体阴性组自身抗体检出率为44.4%（12/27），但滴度均lt;1∶320；治疗前抗甲状腺球蛋白抗体阳性患者会出现较高的甲状腺功能异常率。 结论 慢性丙型肝炎合并血清自身抗体阳性的患者干扰素应答率高于阴性组，但应注意抗甲状腺球蛋白抗体，以预测不良反应。【Abstract】 Objective To explore the consolidation of serum autoantibodies in chronic hepatitis C patients treated with interferon. Methods The clinical data of 66 patients with chronic hepatitis C treated with interferon from February 2005 to February 2008 were retrospectively analyzed. The relationship between the consolidation of serum autoantibodies and the effect of interferon was observed. Results ①There were 39 patients with positive autoantibodies; the positive rate was 59.1% (39/66) and ANA was the main antibody. ②The appearance of autoantibodies correlated with the patients′ ages but not with the sexes and CVRNA quantification. ③The interferon response rate in autoantibodies positive group was 66.7% (26/39) which was much higher than that in the negative group; the difference between the two groups was significant. ④After the interferon treatment, the autoantibody detection rate in autoantibody negative group was 44.4%(12/27)and the titer was lower than 1:320; before the treatment, the anti-thyroglobulin antibody-positive patients had a higher rate of thyroid dysfunction. Conclusion The interferon response rate in chronic hepatitis C patients with positive serum autoantibodies is higher than that in the patients with negative serum autoantibodies. Anti-thyroglobulin antibodies should be noted to predict the adverse effects.
ObjectiveTo comprehensively analyze the relationship between microRNAs and intervertebral disc degeneration at home and abroad. MethodsThe literature about the relationship between microRNAs and intervertebral disc degeneration was reviewed and analyzed. ResultsMicroRNA can lead to intervertebral disc degeneration by regulating the gene expression, thus influencing the cell's apoptosis and proliferation, increasing of the production of inflammatory mediator and protease, which play important roles in intervertebral disc degeneration. ConclusionMicroRNA is a research focus in the field of intervertebral disc degeneration. Further research of the relationship between microRNAs and intervertebral disc degeneration will help to identify the pathogenesis of intervertebral disc degeneration and furnish the new ideal for the diagnosis and treatment of intervertebral disc degeneration.
ObjectiveTo evaluate the efficacy of video-assisted thoracoscopic sleeve lobectomy in the treatment of central non-small cell lung cancer.MethodsThe clinical data of 105 patients with central non-small cell lung cancer who underwent sleeve lobectomy surgery in the Second Hospital of Shanxi Medical University and Shanxi Cancer Hospital from December 2014 to December 2019 were retrospectively analyzed, including 83 males and 22 females, with an average age of 57.4 (32.6-77.8) years and weight of 62.5 (52.4-79.1) kg. Thirty-five patients received video-assisted thoracoscopic sleeve lobectomy (a group A), and 70 patients received traditional thoracotomy sleeve lobectomy (a group B). The operation time, intraoperative blood loss, number of lymph node dissection, postoperative complication rate, early postoperative mortality, total thoracic drainage volume at 24 hours, time of indwelling chest tube after operation, pain score at 24 hours after operation, postoperative hospital stay, postoperative short-term (1 month, 6 months and 1 year) quality of life score and postoperative 3-year survival rate of two groups were compared.ResultsThere was statistical difference in the operation time (228.1±24.7 min vs. 175.0±23.7 min, P=0.02), postoperative complication rate (28.6% vs. 34.3%, P=0.04), postoperative pain score at 24 h (3.6±3.5 points vs. 5.9±2.0 points, P=0.03) and postoperative indwelling chest tube time (5.0±2.9 d vs. 8.4±2.1 d, P=0.04) between the two groups. There was no statistical difference in the intraoperative blood loss (182.5±36.9 mL vs. 189.8±27.5 mL, P=0.34), number of lymph node dissections (11.1±2.6 vs. 12.3±1.9, P=0.49), early postoperative mortality (2.9% vs. 4.3%, P=0.31), total thoracic drainage volume at 24 h after surgery (346.8±91.1 mL vs. 329.8±101.4 mL, P=0.27), postoperative hospital stay (7.9±4.2 d vs. 8.5±3.4 d, P=0.39) and 3-year postoperative survival rate (68.6% vs. 72.9%, P=0.82) between the two groups.ConclusionVideo-assisted thoracoscopic sleeve lobectomy for the treatment of central non-small cell lung cancer is safe and feasible. Compared with traditional thoracotomy for sleeve lobectomy, fewer postoperative complications occur, body recovers faster and the quality of life is higher within the postoperative 6 months. Besides, the 3-year survival rate can achieve similar oncological prognosis results.
目的 研究低碘饮食对大鼠甲状腺功能的影响及c-Jun在肾组织中的表达差异，探讨c-Jun在低碘大鼠肾脏组织中表达的意义。 方法 给予Wistar大鼠低碘饲料，通过饮用不同碘浓度饮水分组,测定甲状腺功能。利用免疫组织化学方法分析肾脏组织中c-Jun的激活变化情况。 结果 重度低碘组与轻度低碘组、正常对照组比较三碘甲状腺原氨酸(TT3)、血清总甲状腺素(TT4)、游离三碘甲状腺原氨酸(FT3)、游离甲状腺素(FT4)均明显下降(Plt;0.05)。轻度低碘组与正常对照组相比，TT4、FT3明显下降(Plt;0.05)，TT3、FT4稍有降低(Pgt;0.05)。c-Jun在低碘大鼠肾组织中表达增强，与低碘程度有依赖关系，且在肾小球内的表达明显强于肾小管。 结论 低碘摄入可引起肾组织中c-Jun的过度表达，进而引起肾脏损伤。
