WT1基因与急性髓系白血病的预后及主动特异性免疫治疗的研究进展

WT1基因位于人类染色体11p13，在80%的急性髓系白血病（acute myeloid leukemia，AML）患者中高表达，是AML预后不良的分子标志，可作为AML预后评估和微小残留病变（minimal residual disease，MRD）监测的有效指标。由于WT1在AML中均有异常高表达，故认为是一种AML抗原，可作为特异性免疫治疗的新靶点。一些小规模的临床试验证实以WT1为靶点的免疫治疗是有效的、安全的，这些免疫治疗可作为那些有高危复发风险及初始标准化疗失败的AML患者的辅助治疗。本文就近几年WT1与AML的预后及有关以WT1为靶点的主动特异性免疫治疗的研究进展予以综述。     

The prognostic role of tumour‐infiltrating lymphocytes in oral squamous cell carcinoma: A meta‐analysis

It has been suggested that tumour‐infiltrating lymphocytes (TILs) are associated with the progression of oral squamous cell carcinoma (OSCC). However, the prognostic value of TILs is inconclusive due to the heterogeneity of immune cells within the tumour microenvironment. In this meta‐analysis, we aimed to assess the prognostic value of TILs in OSCC. The PubMed, Cochrane, Embase, Scopus and Web of Science databases were searched up to April 20, 2019, and 33 studies were ultimately included in this meta‐analysis. Our pooled meta‐analysis showed that high infiltration of CD8⁺ TILs, CD45RO⁺ TILs and CD57⁺ TILs favoured better overall survival (OS). However, high infiltration of CD68⁺ macrophages and CD163⁺ macrophages was associated with poor prognosis in OSCC. These findings suggest that CD8⁺ TILs, CD45RO⁺ TILs, CD57⁺ TILs, CD68⁺ macrophages and CD163⁺ macrophages might serve as novel prognostic factors and therapeutic targets in OSCC.

Five Year Trends in the Utilization of Robotic Bariatric Surgery Procedures,United States 2015–2019

Purpose

Robotic approaches have been steadily replacing laparoscopic approaches in metabolic and bariatric surgeries (MBS); however, their superiority has not been rigorously evaluated. The main goal of the study was to evaluate the 5-year utilization trends of robotic MBS and to compare to laparoscopic outcomes.

Methods

Retrospective analysis of 2015–2019 MBSAQIP data. Kruskal-Wallis test/Wilcoxon and Fisher’s exact/chi-square were used to compare continuous and categorical variables, respectively. Generalized linear models were used to compare surgery outcomes.

Results

The use of robotic MBS increased from 6.2% in 2015 to 13.5% in 2019 (N= 775,258). Robotic MBS patients had significantly higher age, BMI, and likelihood of 12 diseases compared to laparoscopic patients. After adjustment, robotic MBS patients showed higher 30-day interventions and 30-day readmissions alongside longer surgery time (26–38 min).

Conclusion

Robotic MBS shows higher intervention and readmission even after controlling for cofounding variables.

目的对儿童血管迷走性晕厥(VVS)的传统诊断程序与新诊断程序进行卫生经济学评价。方法采用回顾分析方法,根据不同的诊断程序(即传统诊断程序和新诊断程序),将1995年1月至2005年5月北京大学第一医院儿科确诊的81例VVS患儿分为2组,分别计算其就诊费用、检查费用、住院日、确诊日等,运用经济学最小成本分析法进行评价。结果新诊断程序的平均就诊费用比传统诊断程序少耗费1668.80元;新诊断程序的平均就诊检查费用比传统诊断程序少耗费1413.30元。结论新诊断程序对确诊儿童血管迷走性晕厥具有良好的经济学效益,值得临床推广。     

血清S100ββ变化与老年患者腹部手术后认知功能障碍的关系

目的观察老年患者腹部手术后S100ββ蛋白的变化以及术后认知功能障碍(POCD)的发生情况,并探讨二者的关系。方法26例65岁以上的老年患者ASAⅡ~Ⅲ级,行腹部手术。监测术前、术毕、术后6、24、48、72h血清S100ββ的变化,并评定术前及术后1周内的认知功能。结果老年患者血清S100ββ蛋白在术毕最高(P<0·01),术后6h和24h逐渐下降,但术后48h再次上升(P<0·01),术后72h回复至术前水平。26例老年患者腹部手术后1周内有7例发生POCD。POCD组与非POCD组相比,术毕及术后6h血清S100ββ蛋白水平明显增高(P<0·05)。结论老年患者腹部手术后POCD的发生与血清S100ββ蛋白的变化有密切关系。血清S100ββ蛋白可作为评估老年患者术后发生POCD的重要指标。
