To the Editor： We thank Dr. wang, et al. for the comments in our article. With regard to the flint comment point, we agreed with them that Connack-Lehane grades 34 with Macintosh laryngoscope should be defined as difficult laryngoscopy. The definition of difficult airway in our paper should be difficult laryngoscopy, not difficult airway.

目的探讨术中正性暗示对腹腔镜手术患者术中应激反应及术后疼痛的影响。方法选取2022年12月至2023年12月手术室行腹腔镜手术患者136例,使用随机数字表法分为观察组与对照组,每组68例。对照组患者术中接受常规操作与护理,观察组患者术中接受常规操作及术中正性暗示护理。记录术中患者应激状态指标,并比较患者心理状态,术后疼痛评分以及术后并发症。结果观察组患者术中应激状态指标水平均低于对照组患者(P <0.05)。术后观察组患者阳性症状总分和广泛性症状总分高于对照组患者,阴性症状总分低于对照组患者(P <0.05)。治疗后,对照组中度及严重疼痛发生率更高,观察组无痛及轻微痛发生率更高(P <0.05)。对照组术后并发症发生低于对照组(P <0.05)。结论术中正性暗示能够有效改善患者的心理状态,减少负性情绪,且有助于减轻术后疼痛,以及降低术后并发症的发作风险。

目的探索华北地区成年人健康生活方式依从性、影响因素及其与心血管死亡和全因死亡的关系。方法选取2015—2021年心血管病高危人群早期筛查与综合干预项目中来自华北地区62个项目点,年龄35~75岁人群为研究对象。本研究调查不吸烟、不饮酒或适量饮酒、充足体力活动、健康饮食4种健康生活方式,通过被动随访获取研究对象的生存状态。采用多元logistic回归分析探索人群特征与健康生活方式的相关性,使用多元Cox比例风险回归模型分析健康生活方式与全因死亡和心血管死亡的相关性。结果228876名研究对象中,不吸烟178178人(77.85%)、不饮酒或适量饮酒211997人(92.63%)、有充足体力活动70391人(30.76%)、遵循健康饮食37780人(16.51%),只有10669人(4.66%)遵循上述4种健康生活方式。女性、老年人、非农民工作者、高收入或高学历人群、有心血管病病史的受试者更有可能坚持种类更多的健康生活方式(P<0.01)。在中位随访的3.55年中,经多变量调整发现,坚持不吸烟和充足体力活动的研究对象有更低的心血管死亡风险和全因死亡风险。随着健康生活方式数量的增加,心血管死亡风险和全因死亡风险呈下降趋势,与没有任何1种健康生活方式的居民相比,坚持4种健康生活方式的人群心血管死亡风险(HR=0.39,95%CI:0.22~0.69)和全因死亡风险(HR=0.59,95%CI:0.43~0.80)更低。结论华北地区健康生活方式依从性虽高于全国平均水平,但仍未达到理想状态,应基于影响因素和华北地区特点制定针对性的健康促进策略,以期改善华北地区人群健康状况,降低疾病负担。
