特发性肺纤维化患者慢性肺部感染的发生特点及病原学研究

目的 探讨特发性肺纤维化（IPF）患者慢性肺部感染（CPI）的发生特点及病原学特征。方法 选择我院收治的195例IPF患者为研究对象，将患者分为四组，A组：IPF诊断时CPI阴性且随访期间未出现CPI;B组：IPF诊断为CPI阴性，但在随访期间出现CPI;C组：IPF诊断为CPI阳性，但在随访期间未出现另一种CPI;D组：IPF诊断为CPI阳性，并在随访期间出现另一种CPI。记录患者基线资料及生存状态。结果 在IPF诊断时，31例患者出现CPI（C+D组）,在164例诊断IPF时没有CPI的患者（A+B组）中，28例患者（B组）在平均6.1年（0.01～15.00年）的随访期内出现了CPI。在这28例B组患者中，25例（89.29%）只有1种病原体，3例（10.71%）有2种病原体，2例患者发生了二次感染。检出结核分枝杆菌14例（45.16%）,禽类分支杆菌复合体10例（32.26%）,曲霉属真菌5例（16.13%）,诺卡氏菌属1例（3.23%）,禽类分支杆菌复合体及曲霉属真菌混合感染1例（3.23%）。多变量COX分析发现，BMI<21 kg/m2、PaO2<70 mmHg、KL-6≥2000 U/ml是影响患者CPI发生的独立性危险因素。Log-rank检验显示，有CPI发展组和无CPI发展组患者的生存率差异无统计学意义（P=0.416）。结论 结核分枝杆菌、非结核分枝杆菌、曲霉菌和诺卡氏菌是CPI患者的最常见病原菌。在IPF随访过程中，尤其是BMI<21 kg/m2、PaO2<70 mmHg、KL-6≥2000 U/ml的患者，临床医生应注意CPI的变化情况。     

Magnetic resonance elastography with guided pressure waves

Magnetic resonance elastography aims to non-invasively and remotely characterize the mechanical properties of living tissues. To quantitatively and regionally map the shear viscoelastic moduli in vivo, the technique must achieve proper mechanical excitation throughout the targeted tissues. Although it is straightforward, ante manibus, in close organs such as the liver or the breast, which practitioners clinically palpate already, it is somewhat fortunately highly challenging to trick the natural protective barriers of remote organs such as the brain. So far, mechanical waves have been induced in the latter by shaking the surrounding cranial bones. Here, the skull was circumvented by guiding pressure waves inside the subject's buccal cavity so mechanical waves could propagate from within through the brainstem up to the brain. Repeatable, reproducible and robust displacement fields were recorded in phantoms and in vivo by magnetic resonance elastography with guided pressure waves such that quantitative mechanical outcomes were extracted in the human brain.

三联预康复策略在肝癌腹腔镜肝切除术中的应用价值

目的:探讨三联预康复策略在肝癌腹腔镜肝切除术中的应用价值。方法:选取2015年1月至2018年1月四川大学华西医院胆道外科收治的120例行腹腔镜肝切除术的肝癌患者，按随机数字表法分为观察组及对照组各60例。观察组在门诊收治当日开始三联预康复策略干预，干预时间约2～4周；对照组予以常规肝癌腹腔镜肝切除术术前准备。于干预前、术前1天及术后4周分别记录六分钟步行距离(6MWT)、医院焦虑抑郁量表(HADS)评分、健康调查简表(SF-36)评分及检测血清白蛋白(ALB)、前白蛋白(PA)、转铁蛋白(TRF)水平。结果:术前1天，观察组6MWT、血清ALB、PA、TRF水平高于干预前(P＜0.05)；对照组6MWT、血清ALB、PA、TRF水平与干预前差异无统计学意义(P＞0.05)；术后4周，观察组6MWT、血清ALB、PA、TRF水平与干预前差异无统计学意义(P＞0.05)；对照组6MWT、血清ALB、PA、TRF水平低于干预前(P＜0.05)；术前1天、术后4周观察组HADS评分低于干预前，SF-36评分高于干预前(P＜0.05)；对照组HADS、SF-36评分与干预前差异无统计学意义(P＞0.05)；术前1天、术后4周，观察组6MWT、SF-36评分、血清ALB、PA、TRF水平高于对照组，HADS评分低于对照组(P＜0.05)。结论:三联预康复策略应用于肝癌腹腔镜肝切除术可明显改善患者围术期活动能力、心理状态及营养状况，加速患者术后恢复。
