American Cancer Society nutrition and physical activity guideline for cancer survivors

The overall 5-year relative survival rate for all cancers combined is now 68%, and there are over 16.9 million survivors in the United States. Evidence from laboratory and observational studies suggests that factors such as diet, physical activity, and obesity may affect risk for recurrence and overall survival after a cancer diagnosis. The purpose of this American Cancer Society guideline is to provide evidence-based, cancer-specific recommendations for anthropometric parameters, physical activity, diet, and alcohol intake for reducing recurrence and cancer-specific and overall mortality. The audiences for this guideline are health care providers caring for cancer survivors as well as cancer survivors and their families. The guideline is intended to serve as a resource for informing American Cancer Society programs, health policy, and the media. Sources of evidence that form the basis of this guideline are systematic literature reviews, meta-analyses, pooled analyses of cohort studies, and large randomized clinical trials published since 2012. Recommendations for nutrition and physical activity during cancer treatment, informed by current practice, large cancer care organizations, and reviews of other expert bodies, are also presented. To provide additional context for the guidelines, the authors also include information on the relationship between health-related behaviors and comorbidities, long-term sequelae and patient-reported outcomes, and health disparities, with attention to enabling survivors' ability to adhere to recommendations. Approaches to meet survivors' needs are addressed as well as clinical care coordination and resources for nutrition and physical activity counseling after a cancer diagnosis.

迭代重建技术对双低剂量肺动脉CT血管造影图像质量分析

目的分析迭代重建技术对双低剂量肺动脉CT血管造影(CTA)检查图像质量的影响。 方法选取2018年2月至2021年2月我院行肺动脉CTA检查73例，随机分为对照组35例，观察组38例。对照组采用常规剂量滤波反投影重建，观察组采用双低剂量iDose⁴迭代重建技术。比较两组图像参数[背景噪声值(BN)、肺动脉CT值平均值(SI_vessel)、信噪声比(SNR)、对比噪声比(CNR)]、辐射剂量[容积CT剂量指数(CTDI_vol)、剂量长度指数(DLP)、有效吸收剂量(ED)]及图像质量，并分析典型病例的影像学表现。 结果观察组BN、SI_vessel、SNR、CNR参数高于对照组(P<0.05)；观察组CTDI_vol、DLP、ED辐射剂量低于对照组(P<0.05)；观察组图像质量优良率94.74%高于对照组77.14%(P<0.05)。 结论迭代重建技术应用于双低剂量肺动脉CTA检查中能降低辐射剂量，提高信噪比，改善图像质量。     

10例Alagille综合征患儿行肝移植的围手术期护理

总结10例Alagille综合征患儿行肝移植术的围手术期护理经验。护理要点包括：多器官功能评估，做好术前护理；早期营养评估，启动个体化营养干预；精准容量管理，保证脏器最佳灌注；采取多形式隔离措施，加强感染预防与控制；实施预见性心理护理，缓解患儿不良情绪；采用多模式随访管理，提供延续护理服务。经过精心的治疗护理，10例患儿均康复出院，随访2个月至1年，恢复良好。     

滋肾育胎丸加减方预防ACA阳性者不良妊娠结局的效果及机制研究＊

目的 探讨滋肾育胎丸加减方预防抗磷脂抗体（ACA）阳性者不良妊娠结局的效果及机制研究。方法 选取2016年2月至2019年2月我院收治的89例ACA阳性，先兆性流产或有习惯性流产（RSA）史患者，将采用西医治疗的40例作为对照组，将采用西医联合滋肾育胎丸加减方治疗的49例作为观察组，比较两组中医证候疗效、中医证候积分、ACA-IgA、ACA-IgM、ACA-IgG、凝血指标［血小板聚集功能（PAF）、活化蛋白C（PC）、抗凝血酶（AT）、纤溶酶原激活抑制物-1（PAI-1）］、Th1/Th2细胞因子［干扰素γ（IFN-γ）、白介素-2（IL-2）、白介素-4（IL-4）、白介素-10（IL-10）］、妊娠结局、安全性。结果 治疗2周后检测ACA，观察组2例未降低，对照组11例未降低，观察组未降低患者占比低于对照组（P<0.05）；观察组总有效率100.00%高于对照组85.00%（P<0.05）；观察组治疗4周、7周后中医证候积分低于对照组（P<0.05）；观察组治疗4周、7周后ACA-IgA、ACA-IgM、ACA-IgG低于对照组（P<0.05）；观察组治疗4周、7周后PAF、PAI-1低于对照组，PC、AT高于对照组（P<0.05）；观察组治疗4周、7周后IFN-γ、IL-2低于对照组，IL-4、IL-10高于对照组（P<0.05）；观察组活产率95.92%高于对照组80.00%（P<0.05）；组间不良反应总发生率比较，差异无统计学意义（P>0.05）。结论 动态监测ACA对滋肾育胎丸加减方精准应用具有指导意义，指导滋肾育胎丸加减方通过调理脏腑、气血、经络功能，改善先兆性流产或有RSA史患者临床症状及凝血因子指标，降低ACA水平，并可改善患者免疫耐受功能，提高胎儿活产率，且安全性高。
