浅谈职业病危害因素苯的识别与化学品安全说明书的关系

新型冠状病毒肺炎（新冠肺炎）对人民的生命健康造成了巨大的威胁。在新冠肺炎疫情下，如何应对肝胆外科肝癌患者的门诊筛查、病房管理以及安全地实施肝癌手术，都是对肝胆外科医师提出的新挑战。我们认为，该病的临床处置应在筛查新冠肺炎的前提下，遵循正规操作流程，做好充分防护。对于需要急诊治疗但无法排除新冠肺炎的肝癌患者，须综合考虑患者的病情严重程度、手术方式及手术室条件，慎重制定个体化治疗方案。整个诊疗过程必须遵从既保证患者的安全及疗效，又要降低医护人员感染风险的原则。     

The effects of curcumin supplementation on body mass index,body weight,and waist circumference in patients with nonalcoholic fatty liver disease: A systematic review and dose–response meta‐analysis of randomized controlled trials

Nonalcoholic fatty liver disease (NAFLD) is a major cause of liver‐related morbidity; its prevalence is elevating due to the rising epidemic of obesity. Several clinical trials have examined the effects of curcumin supplementation on anthropometric variables in NAFLD patients with inconclusive results. This dose–response meta‐analysis aimed to evaluate the impact of curcumin supplementation on body mass index (BMI), body weight, and waist circumference (WC) in patients with NAFLD. A systematic review of the literature was conducted using PubMed/Medline, ISI Web of Science, Scopus, Cochrane Library, EMBASE, Google Scholar, Sid.ir, and Magiran.com to identify eligible studies up to March 2019. A meta‐analysis of eligible studies was performed using the random‐effects model to estimate the pooled effect size. Eight randomized controlled trials with 520 participants (curcumin group = 265 and placebo group = 255) were included. Supplementation dose and duration ranged from 70 to 3,000 mg/day and 8 to 12 weeks, respectively. Curcumin supplementation significantly reduced BMI (weighted mean difference [WMD] = ?0.34 kg/m², 95% CI [?0.64, ?0.04], p < .05) and WC (WMD = ?2.12 cm, 95% CI [?3.26, ?0.98], p < .001). However, no significant effects of curcumin supplementation on body weight were found. These results suggest that curcumin supplementation might have a positive effect on visceral fat and abdominal obesity that have been associated with NAFLD.     

TACE 术前天冬氨酸氨基转移酶与淋巴细胞比值对原发性肝癌并门脉癌栓患者预后预测的价值

目的 探讨肝动脉化疗栓塞（transcatheter arterial chemoembolization，TACE）术前天冬氨酸氨基转移酶与淋巴细胞比值（aspartate aminotransferase to lymphocyte ratio index，ALRI）在原发性肝癌并门脉癌栓（primary liver cancer-portal vein tumor thrombosis，PLC-PVTT）患者预后预测中的价值。方法 选取2013年11月21日至2018年8月22日于广西医科大学附属肿瘤医院接受TACE治疗的175例PLC-PVTT患者为研究对象。采用时间依赖性ROC曲线确定ALRI的最佳临界值。采用Cox 回归模型分析总生存期（overall survival，OS）的独立预测因素，Kaplan-Meier法计算生存率。结果 ROC曲线显示，ALRI的最佳临界值为49.37，对应曲线下面积为0.71。Kaplan-Meier分析显示，ALRI>49.37的患者OS较ALRI≤49.37的患者短（P=0.003）。Cox 回归分析结果显示，ALRI>49.37、行1次以上TACE治疗、Child-Pugh分级B级、凝血酶原时间≥13 s是患者TACE术后OS的独立危险因素（均P＜0.05）。结论 TACE术前ALRI>49.37是PLC-PVTT患者OS的独立危险因素。     

连续护理干预模式对脊柱骨折伴脊髓损伤患者术后康复效果的研究

目的研究分析连续护理干预模式对脊柱骨折伴脊髓损伤患者术后康复效果。方法本项研究回顾了2017年2月—2018年7月间在某院采取了脊柱骨折伴脊髓损伤治疗的52例患者整个治疗过程的资料,将所有的患者使用数字双盲法将其分为了对照组(n=26)和观察组(n=26)。对照组患者使用护理措施为常规护理措施,观察组使用的护理措施为连续护理干预模式,在患者治疗完成后对比两个不同组别患者在围手术期期间各类指标和出现并发症概率。结果对照组患者手术下床活动时间、住院时间、住院所需费用以及患者并发症发生率均显著高于观察组,组别间数据对比差异具有统计学意义(P<0.05)。结论医护人员在进行脊柱骨折伴脊髓损伤患者的护理工作当中,对其采取连续护理模式可以降低患者并发症发生率,缩短患者住院时间,对患者身体的恢复具有显著意义。

Características clínicas y pronóstico de la lesión medular traumática en pacientes mayores de 75 años

ObjectiveTo analyze the incidence and characteristics of traumatic spinal cord injury (SCI) in geriatric population of Galicia (Spain), hospital management and functional prognosis.MethodsComparative retrospective study. Patients admitted with acute traumatic SCI during the time period between January 2010 and December 2016 were included. Two groups established: The elderly over and under 75 years of age, with the latter acting as a control group.ResultsThree hundred seventy-nine patients were studied (27.2% ≥75 years). The main etiology in the >75 years group were falls: 80.6%. There were 65.7% who presented incomplete spinal cord injuries with mean motor index (MI) of 44.9/100. Upon discharge, 90.8% were dependent. Hospital mortality was 34.9%. Those >75 years suffered from more cervical injuries (74.8 vs. 51.2%; p<0.001), longer delay in diagnosis (31.1 vs. 9.2%; p<0.001) and higher hospital mortality (34.9 vs. 3.2%; p<0.001). Fewer surgical interventions were performed, with a longer delay. Percentages for admission into ICU, mechanical ventilation and performing a tracheostomy proved to be similar. There were no significant differences found in the evolution according to the ASIA scale or the MI.Conclusions1) The frequency of traumatic SCI in the elderly in Galicia is high; 2) Neurological evolution is similar to younger patients but the level of dependence is higher; 3) The level of care provided is similar in both groups, except for the surgical indication, and 4) Hospital mortality is high.
