EFNB2对膀胱癌细胞增殖、侵袭及迁移的影响及其机制

目的 研究EFNB2对膀胱癌细胞增殖、凋亡、侵袭和迁移等生物学功能的影响，探讨其作为免疫治疗的可能性。方法 以膀胱癌细胞系T24、5637、J82和UM-UC-3细胞为研究对象，选用人膀胱上皮永生化细胞系SV-HUC-1细胞作为阴性对照。通过慢病毒载体转染shRNA-EFNB2进行敲低实验，然后分别采用qRT-PCR和Western blot检测细胞中EFNB2的mRNA和蛋白表达水平；CCK8和克隆形成实验检测细胞增殖活力；流式细胞术检测细胞周期和细胞凋亡率；Transwell和细胞划痕实验检测细胞侵袭和迁移能力；Western blot检测Bcl2、Bax、Vimentin和E-cadherin的蛋白表达水平。结果 与人膀胱上皮永生化细胞系SV-HUC-1细胞相比，膀胱癌细胞系中EFNB2的表达水平显著增高,其中以T24细胞表达最高(P<0.01)。敲低T24细胞系EFNB2基因表达后，T24细胞增殖活力显著下降(P<0.05)；细胞周期虽然尚未有显著变化，但细胞凋亡率显著增高(P<0.05)，并且抗凋亡蛋白Bcl2表达显著下降（P<0.05）,促凋亡蛋白B...     

远程医疗机器人在心脏死亡器官捐献肝移植术后随访中的应用

目的探讨远程医疗机器人在心脏死亡器官捐献(DCD)肝移植受体术后随访中的应用效果。方法研究对象为西安交通大学第一附属医院2014年1月至2017年12月的100例DCD肝移植受体。根据随访方式不同,将受体分为研究组(50例,采用远程医疗机器人随访)和对照组(50例,采用传统电话随访)。分析并比较研究组和对照组DCD肝移植受体的术后3个月的依从性(服药依从性、自我监测、生活依从性和随访依从性)、随访时间以及随访满意度。结果研究组的服药依从性、自我监测、生活依从性、随访依从性及依从性总分的得分均明显高于对照组(均为P0.05)。研究组肝移植受体的每次随访时间为(9±4)min,明显短于对照组的(13±4)min(t=-4.452, P0.001)。研究组肝移植受体的术后随访满意度为(19.8±2.6)分,明显高于对照组的(16.2±3.1)分(t=6.234, P0.001)。结论远程医疗机器人在DCD肝移植受体术后随访中的应用效果较满意,值得临床推广,其有望成为DCD肝移植受体术后随访中不可缺少的一部分。

经鼻高流量氧气湿化治疗老年慢性阻塞性肺疾病急性加重合并呼吸衰竭的可行性研究

ObjectiveTo investigate the feasibility of transnasal heated humidified high flow nasal cannula oxygen therapy (HFNC) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with respiratory failure in elderly patients. MethodsA total of 176 elderly patients with AECOPD complicated with respiratory failure who were hospitalized at Peking University Shougang Hospital from December 2016 to January 2022 were enrolled, including 82 patients in an HFNC group and 94 patients in an NPPV group. After treatment, pulse oxygen saturation (SPO₂), arterial partial pressure of carbon dioxide (PaCO₂), oxygenation index (OI), respiratory rate (RR), heart rate (HR), mean arterial pressure (MAP), comfort score, discharge rate, rate of endotracheal intubation, rate of transfer to intensive care unit (ICU), and mortality were compared between the two groups. The independent sample t-test was used for comparison between the two groups. Statistical data are expressed in percentage or number of cases and the χ² test was used for their comparisons. ResultsThe SPO₂ values at 30 min, 1 h, and 6 h were significantly higher in the HFNC group than in the NPPV group (t=-2.049,-2.618, and -3.314, P=0.043, 0.010, and 0.001, respectively). SPO₂ before discharge was significantly lower than that of the NPPV group (t=2.162, P=0.033), but OI at each time point and before discharge had no statistical significance (P＞0.05). MAP at 6 h was significantly higher in the HFNC group than in the NPPV group (t=-2.209, P=0.029), but within the normal range. HRs at 2 h and 3 h in the HFNC group were significantly higher than those of the NPPV group (t=-2.199 and -2.336, P=0.030 and 0.021, respectively). There were no significant differences in RR, HR, or MAP between the two groups at other time points and before discharge (P＞0.05). There was no significant difference in PaCO2 between the two groups (P＞0.05). Comfort score in the HFNC group was significantly higher than that of the NPPV group (t=-46.807, P＜0.001). There were no significant differences in discharge rate, ICU transfer rate, endotracheal intubation rate, and mortality between the two groups (P＞0.05). ConclusionHFNC is as effective as NPPV in treating elderly patients with AECOPD complicated with type Ⅰ or mild type Ⅱ respiratory failure, and HFNC is more comfortable than NPPV.
