微创Chevron-Akin截骨术治疗轻中度拇外翻的早期疗效分析

目的:探讨微创Chevron-Akin(minimally invasive Chevron-Akin,MICA)截骨术治疗轻中度拇外翻的早期临床疗效。方法:自2019年6月至2021年4月,采用MICA截骨术治疗26例(29足)轻中度拇外翻患者,其中男1例,女25例;年龄19~78(38.3±19.5)岁。观察并比较手术前后拇外翻角(hallux valgus angle,HVA),第1、2跖骨间角(intermetatarsal angle,IMA),第1跖骨短缩。末次随访时采用美国骨科足踝外科协会(American Orthopedic Foot and Ankle Society,AOFAS)前足评分系统及视觉模拟评分(visual analogue scale,VAS)评价治疗效果,并记录相关并发症。结果:26例(29足)均获得随访,时间12~33(19.6±5.1)个月。HVA、IMA分别由术前的(32.3±6.6)°、(11.7±3.2)°矫正为术后的(13.0±5.3)°、(6.1±3.2)°,差异有统计学意义(P<0.01);第1跖骨短缩(2.7±1.1) mm。AOFAS评分由术前的(55.7±7.4)分提高到术后的(88.5±7.9)分(P<0.01),其中优15足,良11足,可3足。VAS由术前的(6.5±1.5)分改善为术后的(0.7±0.4)分(P<0.01)。结论:MICA截骨术创伤小,术后恢复快,并发症率低,并且能有效改善拇外翻畸形,是治疗轻中度拇外翻的安全可靠手术方法。     

我国三级医疗机构营养科专业人才队伍情况调查

目的调查分析我国三级医疗机构营养科专业人才队伍情况，提出针对性建议。方法从国家医疗质量管理与控制信息网选取1 283家三级医疗机构调研临床营养专业技术人员数据，应用频数、构成比等进行描述性统计分析。 结果三级医疗机构营养科专业技术人员数量不足且分布不均衡，高层次人才比例偏低。医床比1:556.91，技床比1:841.30，医技比1.51:1，护床比1:1 031.31，均未达到文件标准，营养科医师严重缺编。结论应加强营养科专业人员教育和高层次人才培养，建立规范化培养体系，明确营养科职称评定和岗位技能考核制度，不断扩增专业人才数量，提升临床营养诊疗能力。     

德尔菲法在中医临床证候应用中的系统评价＊

目的 系统评价德尔菲法在中医临床证候应用中的应用现状，为后续规范与完善证候研究方法提供参考。方法 计算机检索五大数据库关于中医临床证候研究中应用德尔菲法的研究，检索时限自建库至2021年6月1日，由两名研究人员独立进行文献筛选、质量评估和资料提取，对质量A级和B级的研究进行分析。结果 经过质量评价共纳入201篇文献，其中原始研究199篇，方法学研究9篇。研究方向包括候分布特点、证候诊断标准、单一证候研究、证候要素研究、证候变化规律等八类。192篇文献对德尔菲法具体实施进行报道。结论 中医临床证候研究中德尔菲法应用整体较为科学，但在证候研究细节实施尚有不足，有待形成符合中医证候特色的德尔菲法标准规范临床应用。     

经鼻高流量氧气湿化治疗老年慢性阻塞性肺疾病急性加重合并呼吸衰竭的可行性研究

ObjectiveTo investigate the feasibility of transnasal heated humidified high flow nasal cannula oxygen therapy (HFNC) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with respiratory failure in elderly patients. MethodsA total of 176 elderly patients with AECOPD complicated with respiratory failure who were hospitalized at Peking University Shougang Hospital from December 2016 to January 2022 were enrolled, including 82 patients in an HFNC group and 94 patients in an NPPV group. After treatment, pulse oxygen saturation (SPO₂), arterial partial pressure of carbon dioxide (PaCO₂), oxygenation index (OI), respiratory rate (RR), heart rate (HR), mean arterial pressure (MAP), comfort score, discharge rate, rate of endotracheal intubation, rate of transfer to intensive care unit (ICU), and mortality were compared between the two groups. The independent sample t-test was used for comparison between the two groups. Statistical data are expressed in percentage or number of cases and the χ² test was used for their comparisons. ResultsThe SPO₂ values at 30 min, 1 h, and 6 h were significantly higher in the HFNC group than in the NPPV group (t=-2.049,-2.618, and -3.314, P=0.043, 0.010, and 0.001, respectively). SPO₂ before discharge was significantly lower than that of the NPPV group (t=2.162, P=0.033), but OI at each time point and before discharge had no statistical significance (P＞0.05). MAP at 6 h was significantly higher in the HFNC group than in the NPPV group (t=-2.209, P=0.029), but within the normal range. HRs at 2 h and 3 h in the HFNC group were significantly higher than those of the NPPV group (t=-2.199 and -2.336, P=0.030 and 0.021, respectively). There were no significant differences in RR, HR, or MAP between the two groups at other time points and before discharge (P＞0.05). There was no significant difference in PaCO2 between the two groups (P＞0.05). Comfort score in the HFNC group was significantly higher than that of the NPPV group (t=-46.807, P＜0.001). There were no significant differences in discharge rate, ICU transfer rate, endotracheal intubation rate, and mortality between the two groups (P＞0.05). ConclusionHFNC is as effective as NPPV in treating elderly patients with AECOPD complicated with type Ⅰ or mild type Ⅱ respiratory failure, and HFNC is more comfortable than NPPV.
