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.

COPD患者联合使用支气管扩张药沙美特罗和噻托溴铵的疗效评估[英]／Baloira VA …//Arch Bronconeumol．

慢性阻塞性肺疾病（COPD）影响了9％的成人，预计到2020年将成为西方国家的第三大死亡原因。治疗的首要原则是缓解症状和减少加重人数。支气管扩张约噻托溴铵为一种长效抗胆碱能药物，最近已成为治疗COPD的一线药物。目前还没有联用两种长效支气管扩张药的研究，本试验旨在确定联用沙美特罗和噻托溴铵是否比单独应用能较好地改善COPD患者的肺功能。

Colles骨折是指桡骨下端2～3cm以内、骨折远端向背及桡侧移位的骨折.本院门诊于1994年1月至2005年4月共诊治Colles骨折240例,其中40例关节内骨折,经闭合复位后,关节面的移位仍大于2mm者,收住院手术治疗;门诊复位满意的200例患者中186例获得随访,总结如下.     

采用改良McBride与Greer手术治疗严重(足母)外翻

目的探讨采用改良McBride与Greer手术(第1跖骨截骨术)治疗严重足母外翻的临床效果。方法采用改良McBride与Greer手术治疗严重足母外翻19例(32足)。术后根据足母外翻矫正情况进行评价。结果随访19例,时间为1.5个月~6年,所有患者术后外形明显改善,复发1足。结论采用改良McBride与Greer手术治疗严重足母外翻是一种安全、有效的治疗方法。     

维生素D受体基因多态性与汉族人群慢性牙周炎易感性的关系

目的 探讨维生素D受体(VDR)基因多态性与汉族人群慢性牙周炎(CP)易感性的关系。方法 收集汉族轻、中、重度CP患者共166例及80名无牙周炎对照者的颊黏膜拭子，以Chelex-100法提取DNA，采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法测定VDR BsmI、VDR ApaI和VDR TaqI的基因型，分析组间基因型分布和等位基因频率的差异。结果 轻、中、重度CP患者中VDR ApaI等位基因A携带者明显多于对照组，重度CP与中度CP、重度CP与轻度CP患者间VDR ApaI基因型的分布差异均有统计学意义，中度CP与轻度CP患者间VDR ApaI基因型分布差异无统计学意义，而VDR BsmI、TaqI位点的基因型分布在患者组和对照组间差异无统计学意义。结论 VDR ApaI等位基因A可能与汉族人群CP的易感性有关。
