Effect of iron deficiency without anaemia on days alive and out of hospital in patients undergoing valvular heart surgery

Comprehensive evidence regarding the treatment of non-anaemic iron deficiency in patients undergoing valvular heart surgery is lacking. This study aimed to investigate the association between non-anaemic iron deficiency and postoperative outcomes in these patients. We retrospectively analysed 321 patients of which 180 (56%) had iron deficiency (defined as serum ferritin < 100 ng.ml^-1 or < 300 ng.ml^-1 with transferrin saturation < 20%). While the iron-deficient group had lower pre-operative haemoglobin levels than the non-iron deficient group (median (IQR [range]) 134 (127–141 [120–172]) g.l^-1, 143 (133–150 [120–179]) g.l^-1, p = 0.001), there was no between-group difference in allogeneic red blood cell transfusion. Median (IQR [range]) days alive and out of hospital at postoperative day 90 was 1 day shorter in the iron-deficient group (80 (77–82 [9–85]) days vs. 81 (79–83 [0–85]) days, p = 0.026). In multivariable analysis, only cardiopulmonary bypass duration (p = 0.032) and intra-operative allogeneic red blood cell transfusion (p = 0.011) were significantly associated with reduced days alive and out of hospital at postoperative day 90. Iron deficiency did not exert any adverse influence on secondary outcomes except length of hospital stay. Our findings indicate that non-anaemic iron deficiency alone is not associated with adverse effects in patients undergoing valvular heart surgery when it does not translate into an increased risk of allogeneic transfusion.     

放疗干预对宫颈癌荷瘤小鼠的抑瘤作用及对Th1/Th2免疫细胞比例的影响

目的探讨放疗干预对宫颈癌荷瘤小鼠的抑瘤作用及其对辅助性T细胞1(Th1)/Th2细胞比例的影响。方法建立宫颈癌荷瘤小鼠模型,随机分为荷瘤组和放疗组,每组各10只,另设对照组10只。放疗组进行放疗干预14天,荷瘤组和对照组不治疗。放疗后4、6、8、10、12、14天测量肿瘤体积;末次治疗后,ELISA法测定血清干扰素-γ(IFN-γ)、白介素-2(IL-2)、IL-4、IL-10含量;计算抑瘤率、胸腺指数和脾脏指数;HE染色观察肿瘤组织学变化;TUNEL染色观察肿瘤组织细胞凋亡情况;流式细胞术检测脾脏Th1/Th2细胞比例;RT-qPCR和Western blot检测脾脏T盒子转录因子(T-bet)、GATA结合蛋白3(GABA-3)mRNA和蛋白表达。结果与荷瘤组比较,放疗组小鼠4、6、8、10、12、14天肿瘤体积及瘤质量减小,血清IL-2、IFN-γ升高,IL-4、IL-10降低,胸腺指数、脾脏指数升高,Th1细胞比例、Th1/Th2增加,Th2细胞比例减少,T-bet mRNA和蛋白及T-bet/GATA-3表达升高,GATA-3 mRNA和蛋白表达降低(P<0.05)。HE染色显示,荷瘤组肿瘤细胞数量较多,核大深染,无明显坏死;放疗组肿瘤细胞数量减少,出现大量坏死组织。TUNEL染色显示,荷瘤组TUNEL阳性细胞较少,放疗组TUNEL阳性细胞明显增多。结论放疗对宫颈癌荷瘤小鼠具有明显抑瘤作用,可能是通过调节T-bet/GATA-3表达,促进Th1/Th2分化平衡,增强机体免疫功能发挥作用。

The Added Value of SARC-F to Prescreening Using FRAX for Hip Fracture Prevention in Older Community Adults

Objectives

To examine the potential added value of a simple 5-item questionnaire for sarcopenia screening (SARC-F) to the Fracture Risk Assessment Tool (FRAX) for hip fracture risk prediction, in order to identify at-risk older adults for screening with dual-energy x-ray absorptiometry (DXA).

多西他赛联合氟尿嘧啶、顺铂方案与多西他赛联合氟尿嘧啶、洛铂方案治疗胃癌的疗效比较

目的:比较多西他赛联合氟尿嘧啶、顺铂方案与多西他赛联合氟尿嘧啶、洛铂方案治疗晚期不可手术胃癌患者的疗效和不良反应。方法:回顾性分析2015年2月至2018年6月126例晚期不可手术的胃癌患者。洛铂组55例:多西他赛+氟尿嘧啶+洛铂，顺铂组71例:多西他赛+氟尿嘧啶+顺铂。洛铂组和顺铂组均21天为一个疗程，连续治疗四个疗程。结果:洛铂组患者客观有效率为50.91%，顺铂组为35.21%，差异无统计学意义（P＞0.05）。洛铂组患者疾病控制率达到83.64%，顺铂组为67.61%，差异有统计学意义（P＜0.05）。洛铂组患者在恶心、呕吐、白细胞减少和四肢麻木方面发生率明显低于顺铂组，差异有统计学意义（P＜0.05）。洛铂组患者血小板减少发生率高于顺铂组，差异有统计学意义（P＜0.05）。洛铂组患者严重不良反应的发生率为21.82%，顺铂组为39.44%，差异具有统计学意义（P＜0.05）。结论:将多西他赛联合氟尿嘧啶、顺铂方案中的顺铂以洛铂替代，取得了更好的疾病控制率，而患者的不良反应更轻，严重不良反应的发生率也更低，值得临床进一步研究。
