目的 观察经鼻高流量氧疗治疗慢性阻塞性肺疾病急性加重期（AECOPD）伴Ⅱ型呼吸衰竭对患者肺功能、血气分析指标的影响。方法 收集2020年3月—2022年3月我院收治的AECOPD伴Ⅱ型呼吸衰竭患者92例,随机分为常规通气组（46例,无创正压通气）、经鼻氧疗组（46例,经鼻高流量氧疗）,测量记录治疗前及治疗后2组患者心率及呼吸频率、血气分析指标、肺功能指标,评估患者舒适度及呼吸困难情况,记录治疗期间并发症。结果 治疗后经鼻氧疗组心率、呼吸频率低于常规通气组（P<0.05）;治疗后经鼻氧疗组二氧化碳分压（PaCO₂）低于常规通气组,动脉血氧分压（PaO₂）高于常规通气组（P<0.05）;治疗后经鼻氧疗组第1秒用力呼出气容积（FEV₁）、用力呼气容积（FVC）高于常规通气组（P<0.05）;治疗后经鼻氧疗组Borg评分低于常规通气组,舒适率高于常规通气组（P<0.05）;经鼻氧疗组并发症发生率低于常规通气组（P<0.05）。结论 给予AECOPD伴Ⅱ型呼吸衰竭患者经鼻高流量氧疗可改善患者肺功能、血气分析指标,促进呼吸困难症状缓解,且可提高患者舒适度,降低并发症发生率。

Objective To observe the effect of nasal high-flow oxygen therapy on pulmonary function and blood gas analysis indexes in patients with acute exacerbation of chronic obstructive pulmonary disease（AECOPD）with type Ⅱ respiratory failure．Methods From March 2020 to March 2022,92 patients with AECOPD complicated with type Ⅱ respiratory failure who were treated in our hospital were enrolled and randomly divided into conventional ventilation group（46 cases,non-invasive positive pressure ventilation）and nasal oxygen therapy group（46 cases,nasal high-flow oxygen therapy）．The heart rate and respiratory rate,blood gas analysis indexes,pulmonary function indexes of the two groups of patients before and after treatment were measured and recorded,the comfort level and dyspnea situation of the patients were evaluated,and the complications during the treatment were recorded．Results After treatment,the heart rate and respiratory rate in the nasal oxygen therapy group were significantly lower than those in the conventional ventilation group（P<0.05）．The partial pressure of carbon dioxide（PaCO₂）in the nasal oxygen therapy group was significantly lower than that in the conventional ventilation group,partial pressure of oxygen（PaO₂）was significantly higher than the conventional ventilation group（P<0.05）．The nasal oxygen therapy group forced expiratory volume in one second,（FEV₁）,forced vital capacity（FVC）were significantly higher than the conventional ventilation group（P<0.05）．The Borg score of nasal oxygen therapy group was significantly lower than the conventional ventilation group,the comfort level was significantly higher than the conventional ventilation group（P<0.05）．The incidence of complications in the nasal oxygen therapy group was significantly lower than that in the conventional ventilation group（P<0.05）．Conclusions Nasal high-flow oxygen therapy for AECOPD patients with type Ⅱ respiratory failure can significantly improve the pulmonary function and blood gas analysis indicators,promote the relief of dyspnea symptoms,improve the comfort level of patients,and reduce the incidence of complications．

目的 分析25羟维生素D[25(OH)D]在新疆汉族及维吾尔族老年男性2型糖尿病(T2DM)合并骨质疏松(OP)患者中的水平及与骨密度(BMD)的相关性。方法 收集住院的汉族、维吾尔族老年男性T2DM患者281例,根据民族及骨密度值将其分为汉族非骨质疏松(NOP)组127人(A组)、汉族骨质疏松(OP)组21人(B组)、维族NOP组103人(C组)、维族OP组30人(D组),记录四组患者的25(OH)D水平并进行比较,分析25(OH)D与BMD的相关性。结果 同一民族中,B组的25(OH)D低于A组(P<0.05),D组的25(OH)D低于C组(P<0.05); T2DM合并OP患者中,D组的25(OH)D低于B组(P<0.05); 相关性分析显示,25(OH)D与BMD呈正相关。结论 维吾尔族老年男性T2DM合并OP患者较汉族患者的25(OH)D水平低,25(OH)D水平低的T2DM患者更易合并OP,25(OH)D检测有助于识别T2DM患者合并OP的风险。

Objective To analysis the level of 25 hydroxy vitamin D[25(OH)D] in Xinjiang Han and Uyghur elderly male patients with T2DM and osteoporosis, and the correlation between 25(OH)D levels and bone mineral density(BMD). Methods We collected 281 cases of T2DM patients from Hans and Uyghurs, divided them into four groups according to the nationality and BMD: Han non-osteoporosis(NOP) group including 127 cases(group A), Han osteoporosis(OP) group 21 cases(group B), Uyghur NOP group 103 cases(group C), Uyghur OP group 30 cases(group D). Recorded and compared their 25(OH)D levels, and analyzed the correlation between 25(OH)D levels and BMD. Results In the same nationality,the level of 25(OH)D in group B were lower than those in group A(P<0.05), and group D were lower than those in group C(P<0.05); In T2DM patients combined with OP, the levels of 25(OH)D in group D were lower than those in group B(P<0.05); Correlation analysis showed that 25(OH)D was positively correlated with BMD. Conclusion The level of 25(OH)D in elderly male patients with T2DM combined with osteoporosis, those of Uyghurs are lower than those of Hans. T2DM patients with lower 25(OH)D level are more likely to combine OP. The 25(OH)D level test may help to identify the risk of combining OP in T2DM patients.
