STEAP1 Inhibits Breast Cancer Metastasis and Is Associated With Epithelial–Mesenchymal Transition Procession

Purpose

Six-transmembrane epithelial antigen of prostate 1 (STEAP1) is a cell surface antigen overexpressed in multiple cancers and is associated with malignancy and disease prognosis. The aims of this study were to evaluate STEAP1 expression in breast cancer and to determine the mechanisms involved.

Ultrasound-Based Carotid Plaque Characteristics Help Predict New Cerebral Ischemic Lesions after Endarterectomy

The aim of this study was to identify the ultrasound-based carotid plaque characteristics associated with new cerebral ischemic lesions after carotid endarterectomy (CEA). Between January 2013 and December 2018, carotid duplex ultrasound was performed in 1061 patients who underwent CEA. Brain magnetic resonance diffusion-weighted imaging (DWI) was performed pre-operatively and within 30 d after CEA. New cerebral ischemic lesions on DWI were observed in 169 patients. The cutoff value gray-scale median (GSM) used to distinguish DWI-positive from DWI-negative patients was 30.5, with an area under the receiver operating characteristic curve of 0.837. A larger proportion of multiple DWI lesions were observed in the GSM ≤30.5 group (59.5% vs. 41.5%, p = 0.030). Univariate and multivariate analyses identified GSM ≤30.5, ulcerated carotid plaques and pre-operative ischemic symptoms as predictors of post-operative cerebral DWI lesions. Our results indicate that ultrasound-based carotid plaque characteristics help predict new cerebral ischemic lesions after CEA.     

针刺配合康复训练治疗脑卒中上肢功能障碍的队列研究

目的:探讨针刺配合康复训练对脑卒中上肢功能障碍患者神经功能特异性烯醇化酶(NSE)、硫化氢(H_2S)、神经营养因子(NGF)与脑血管动力学的影响。方法:选取2016年5月至2017年10月空军军医大学唐都医院收治的脑卒中上肢功能障碍患者198例进行回顾性分析。将患者分为针刺配合康复训练治疗观察组100例,单纯依靠康复训练治疗对照组98例。比较与分析2组治疗前后的NSE、H_2S、NGF与脑血管动力学等。结果:观察组治疗后NSE(12. 36±6. 35)μg/L,H_2S(52. 19±3. 77)μmol/L,NGF(152. 94±32. 67) pg/m L。对照组治疗后NSE (16. 28±7. 45)μg/L,H_2S (36. 67±6. 95)μmol/L,NGF(129. 81±33. 02) pg/m L。观察组治疗后颈动脉血流速度平均值(V_(mean))(26. 45±3. 79) cm/s,血流量(Q_(mean))(18. 52±3. 32) cm~3/s,外周阻力(RV)(82. 37±22. 39) k Pa·s/m,舒张压与临界压差值(DP)(0. 45±0. 08) k Pa. s/m,动态阻力(DR)(32. 36±10. 08) k Pa。对照组治疗后V_(mean)(19. 86±3. 73) cm/s,Q_(mean)(14. 79±2. 72) cm3/s,RV(95. 31±30. 45)k Pa·s/m,DP(0. 63±0. 14) k Pa·s/m,DR(42. 37±9. 67) k Pa。观察组治疗前FMA评分为(38. 41±7. 52)分,治疗后FMA评分为(54. 61±5. 34)分,改善值(16. 22±6. 46)分。MBI指数治疗前为(36. 75±6. 87),治疗后为(60. 33±12. 73),改善值为(23. 58±9. 34)。观察组中医证候积分治疗前(16. 52±0. 68)和治疗后(4. 60±0. 22)。对照组中医证候积分治疗前(16. 95±0. 83)分和治疗后(8. 72±0. 27)分。结论:针刺配合康复训练能够有效的帮助脑卒中上肢功能障碍患者的恢复神经功能,加速脑血管血流速度,减少压强阻力,从而达到治疗患者上肢及手功能,恢复日常生活活动能力的效果。     

伊贝母异甾体生物碱通过Wnt/β-catenin信号通路调节哮喘大鼠气道炎症和气道重塑机制的研究

目的 探讨伊贝母异甾体生物碱对哮喘大鼠气道炎症、气道重塑及Wnt/β-catenin信号通路的影响。方法 本研究采用吸入卵清蛋白（OVA）致敏和激发的方法建立大鼠哮喘模型，连续给予药物7天；抽取支气管肺泡灌洗液（BALF）进行白细胞分类计数，酶联免疫吸附法（ELISA）检测BALF中白介素4（IL-4）、白介素5（IL-5）和白介素13（IL-13）的水平；取肺组织进行苏木精-伊红（HE）染色，观察药物对哮喘大鼠气道重塑的影响；采用Western blot技术考察异甾体生物碱对Wnt/β-catenin信号通路上Wnt5a、Wnt7b和β-catenin蛋白的调节作用。结果 与模型组比较，异甾体生物碱组大鼠肺泡间质炎性细胞浸润和支气管管腔狭窄均显著改善，支气管壁厚度和平滑肌厚度均明显降低；Western blot结果显示异甾体生物碱对于哮喘大鼠Wnt/β-catenin通路上的Wnt5a、Wnt7b和β-catenin蛋白表达均有显著的调节作用。结论 异甾体生物碱对于哮喘相关的病理变化-炎症和气道重塑均有一定的治疗作用，且该治疗作用与Wnt/β-catenin信号通路有关。
