右美托咪定联合综合体温保护对腔镜手术治疗老年恶性肿瘤患者苏醒期质量及免疫功能的影响

目的 探讨右美托咪定联合综合体温保护对腔镜手术治疗老年恶性肿瘤患者苏醒期质量及免疫功能的影响。方法 选择择期行腔镜手术治疗的老年恶性肿瘤患者90例，随机均分为3组：对照组（C组）、体温保护组（T组）和体温保护联合右美托咪定组（T-D组），每组30例。C组常规体温保护，T组和T-D组综合体温保护；T-D组麻醉诱导前10 min泵注右美托咪定0.5 μg/kg。记录3组患者麻醉诱导开始时（T₀）、手术开始30 min（T₁）、60 min（T₂）、90 min（T₃）、120 min（T₄）以及手术结束时（T₅）的鼻咽温度；于T₀、术后2 h（T₆）、24 h（T₇）和48 h（T₈）时抽取静脉血标本，测定T淋巴细胞亚群（CD3⁺、CD4⁺和CD8⁺）和自然杀伤细胞（NK cell）水平；记录患者术中麻醉药物用量及苏醒期质量指标。结果 与T₀比较，C组T₂～T₅时点鼻咽温度均明显降低（P < 0.05）；与C组比较，T组和T-D组T₂～T₅时点鼻咽温度明显升高（P < 0.05）。与T₀时点比较，C组、T组和T-D组T₆、T₇和T₈时点CD3⁺和NK cell活性均明显降低（P < 0.05）；C组在T₆、T₇和T₈时点，T组和T-D组在T₆和T₇时点，CD4⁺活性均明显降低（P < 0.05）。与C组比较，T组和T-D组T₆和T₇时点CD3⁺细胞活性均明显升高（P < 0.05）；T组在T₇时点，T-D组在T₆和T₇时点，CD4⁺细胞活性均明显升高（P < 0.05）；T组在T₇时点，T-D组在T₆、T₇和T₈时点，NK cell活性均明显升高（P < 0.05）。结论 采用体温保护措施联合右美托咪定能够维持老年恶性肿瘤患者的体温稳定，减少围手术期意外低体温（IPH）的发生，并有效提高患者苏醒期质量，减轻免疫抑制程度，加速患者早期恢复。     

脑出血围手术期护理安全中细节管理的重要性分析

目的分析脑出血围手术期护理安全中细节管理的重要性。方法将于2018年6-10月在该院接受治疗的60例脑出血围术期患者作为该研究的常规组。将于2018年11月-2019年3月在该院接受治疗的60例脑出血围术期患者作为该研究的细节组。该院于2018年11月开始实施细节管理,以加强保障脑出血围术期患者的安全。对比两组患者的护理满意度、手术失败率、死亡率、住院时间及日常生活能力。结果细节组护理满意度明显高于常规组(P<0.05)。常规组的手术失败率、死亡率为均高于细节组,差异无统计学意义(P>0.05);细节组的住院时间明显短于常规组(P<0.05),ADL评分明显大于常规组(P<0.05)。结论细节管理在脑出血围手术期护理安全中具有相当重要性,可提升护理满意度,加快恢复速度,提升恢复效果。     

Patient preferences and predicted relative uptake for targeted therapies in metastatic colorectal cancer: a discrete choice experiment

Abstract

Objective

Ras wild-type metastatic colorectal cancers (mCRC) may be treated with anti-vascular endothelial growth factor (VEGF) or anti-epidermal growth factor receptor (EGFR) agents. We aim to estimate patients’ preferences for mCRC treatment and relative importance of cost, efficacy improvement, avoidance of side effects and therapy convenience, and relative uptake between profiles that resemble Bevacizumab (anti-VEGF) and Cetuximab (anti-EGFR), two commonly prescribed mCRC targeted therapies.     

Safety profile of the adjuvanted recombinant zoster vaccine: Pooled analysis of two large randomised phase 3 trials

Background

The ZOE-50 (NCT01165177) and ZOE-70 (NCT01165229) phase 3 clinical trials showed that the adjuvanted recombinant zoster vaccine (RZV) was ≥90% efficacious in preventing herpes zoster in adults. Here we present a comprehensive overview of the safety data from these studies.

Dynamic Indicators That Impact the Outcomes of Thoracic Endovascular Aortic Repair in Complicated Type B Aortic Dissection

PurposeTo investigate dynamic variables obtained from retrospective computed tomography angiography for ability to predict thoracic endovascular aortic repair (TEVAR) outcomes in patients with complicated type B aortic dissection (cTBAD).Materials and MethodsSeventy-nine patients with cTBAD who received TEVAR from March 2009 to June 2018 were retrospectively enrolled. Relative true lumen area (r-TLA) was computed at the level of tracheal bifurcation every 5% of all R-R intervals. Parameters that reflect the state of intimal motion were evaluated, including difference between maximum and minimum r-TLA (D-TLA) and true lumen collapse. The endpoints comprised early (≤ 30 days) and late (> 30 days) outcomes after intervention.ResultsOverall early mortality rate was 13.9% (11/79), and early adverse events rate was 24.1% (19/79). Patients who received TEVAR within 2 days of symptom onset demonstrated the worst outcomes. A longer time of r-TLA < 25% in 1 cardiac cycle (P = .049) and larger D-TLA (P < .001) were correlated to an increased early death. In addition, D-TLA was an independent predictor of early mortality. Area under the curve of D-TLA was 0.849 (95% confidence interval 0.730–0.967) for predicting early mortality and 0.742 (95% CI 0.611–0.873) for predicting early adverse events. Survival and event-free survival rates during follow-up were decreased in the D-TLA > 21.5% group compared with the D-TLA ≤ 21.5% group (all P < .001).ConclusionsLarger D-TLA is correlated with worse postoperative outcomes and might be a crucial parameter for future risk stratification in patients with cTBAD.     

自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期慢性阻塞性肺疾病的临床分析

目的探讨自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期慢性阻塞性肺疾病(COPD)的临床疗效及其对患者炎性因子、免疫功能及肺功能的影响。 方法将2015年5月至2016年5月我院收治的86例老年缓解期COPD患者分为观察组与对照组。对照组给予马来酸茚达特罗治疗，观察组在对照组治疗基础上另给予自血穴位注射疗法。治疗12周后，评价2组临床疗效。治疗前及治疗12周后，分别检测2组患者肺功能指标(FEV₁、FVC与PEF)，炎性因子(IL-8、α1-AT、IL-6及TNF-α)，免疫功能指标(IgG、IgA、CD3^＋及CD4^＋)水平。治疗期间，对2组患者的不良反应进行密切观察。 结果治疗后二组患者各项检测指标均优于治疗前。治疗12周后，观察组总有效率为90.7%，明显高于对照组的72.1%(P<0.05)。治疗12周后，观察组FEV₁、FVC与PEF等肺功能指标，IgG、IgA、CD3^＋及CD4^＋等免疫功能指标水平均明显高于对照组(P<0.05)，而IL-8、α1-AT、IL-6及TNF-α含量分别为(23.23±3.87)ng/L、(3.43±0.41)g/L、(52.25±5.38)ng/L及(43.12±3.98)ng/L，改善程度均明显优于对照组(P<0.05)。治疗期间，2组患者均未出现严重不良反应。 结论自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期COPD疗效确切，可有效改善患者炎症水平，值得进行深入研究。     

白内障围手术期结膜囊菌群分布及药敏试验

目的 分析白内障围手术期结膜囊菌群的分布及药敏试验结果。方法 选取264例白内障患者,分别在患者入院后、手术消毒前、手术消毒后、手术结束后四个时间点取样,进行细菌培养及药敏试验,比较不同时期的细菌培养结果和药敏结果。结果 入院后结膜囊细菌培养阳性率明显高于手术消毒前、手术消毒后及手术结束后;入院后结膜囊细菌培养以表皮葡萄球菌为主;革兰氏阳性球菌对头孢西丁、加替沙星、左氧氟沙星等敏感性较高。结论 表皮葡萄球菌是结膜囊最常见的细菌,术前应常规应用抗生素点眼,聚维酮碘冲洗结膜囊等来预防术后感染性眼内炎。
