背景情况:

皮质细胞衍生的细胞因子与具有鼻息肉的慢性鼻炎 (CRSwNPs) 有关.
短链脂肪酸 (SCFA),微生物代谢物,在炎症中起作用.

研究的目的:

为了研究SCFA在eosinophilic慢性鼻炎 (ECRS) 中的作用.

主要方法:

定量实时PCR分析了鼻息肉组织中的GPR41/FFAR3,GPR43/FFAR2,TSLP,IL-25和IL-33的基因表达.
正常的人类支气管上皮 (NHBE) 细胞被用具有或没有SCFA的多I:C刺激,以测量TSLP.
免疫组织化学评估了eosinophils和Eol-1细胞中的GPR41;评估了Eol-1细胞与酸的活力.

主要成果:

在ECRS鼻息肉 (NP) 中,GPR41和GPR43mRNA表达显着更高.
在ECRS-NP中,TSLP mRNA的表达率升高,与乙氨基酸细胞计数相关.
在NHBE细胞中,SCFA (酸,酸,黄油酸) 抑制了聚I:C诱导的TSLP;酸降低了Eol-1细胞存活率.

结论:

SCFA,特别是酸,可能为ECRS提供治疗策略.
酸通过抑制TSLP和异osinophils显示出潜在的潜力.

关键词:

这是一个ECRS系统.这是TSLP的TSLP.埃索诺菲尔细胞的存在短链脂肪酸是指短链脂肪酸.

Cystic Fibrosis: Management

Cystic Fibrosis: Management

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Acute Respiratory Failure-V

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...
