呼气峰流速(peak expiratory flow, PEF)是指用力呼气的最高流量,能够反应气道的通畅性,是通气功能的常用检查之一,广泛应用于哮喘病人的自我监测。PEF与 FEV1有很好的相关性,尽管PEF的重复性低于FEV1,但PEF较FEV1更易获得。 经过广泛阅读既有研究文献,并进行初步预实验筛选后,本研究选取呼气峰流速作为实验对象,观察其...
Peak Expiratory Flow MMEF: Maximal Mid-Expiratory Flow HDL-C: High-density lipoprotein cholesterol LDL-C: Low-density lipoprotein cholesterol TG: Triglycerides WBCs: White blood cells PLTs: Platelets HGB: Hemoglobin GLU: Blood glucose Cr: Serum creatinine Alb: Serum albumin ALT: ...
This threshold was selected to account for when the extraction software may have missed a peak, thus resulting in one replicate having low to no signal and therefore causing a larger CV across replicates. The data was then filtered for compounds that were found in at least 80 percent of ...
The peak of the enrichment score indicates the strength of gene set enrichment. An enrichment score > 0 indicates upregulation of related gene expressions, while an enrichment score < 0 suggests downregulation of related gene expressions Full size image CS and BMSCs alter the tsRNA ...
- Breath actuated, portable & dose counter- Requires good peak inspiratory flow (min 30 L/min; optimal > 60) Soft Mist Inhaler - press, mist & breathe- mist makes coordination easier, portable, dose counter- Requires actuation/inhalation coordination (easier than MDI), assembly required...
However, in a study of adults and adolescents with asthma, BFC pMDI and BFC Turbuhaler significantly (P , 0.001 for both) improved AM peak expi- ratory flow (PEF; the primary efficacy variable) compared with budesonide pMDI.34 In a 52-week long-term safety study of patients with ...

Tidal volume (VT), peak expiratory flow (PEF), and expiratory flow at 50% tidal volume (EF50) continuously decreased from week 1 to week 16 in the model group, while significantly increased after ECC-BYF administration (Fig. 1b to d). Given forced expiratory volume in 0.3 s/ forced...
