Many epidemiological studies focus on health research in areas with high concentration of PM2.5. To fill the gap, our study investigated acute effects low PM2.5 level (annual average below 35 μg m-³) asthma admissions Xiamen, China. Using a time-stratified case-crossover design, we examined association between and from January 2019 to November 2021. The results showed positive correlation cumulative incidence asthma, lag 0-7 days. Each 10 m-3 increased was associated 0.49% increase incidence. Stratified analysis revealed significant children aged 0-4 years (OR = 2.029, 95% CI 1.359-3.031) elderly population over 75 1.399, 1.092-1.793). Distributed models demonstrated hysteresis effect, lagged observed (lag0-5) (lag3-lag5). multi-pollutant model, considering NO2 O3, consistent results. These findings highlight age-specific susceptibility exposure its impact admissions, even at lower levels pollution. Further is needed inform environmental protection policies public interventions low-pollution environments.

Transient receptor potential vanilloid 1 (TRPV1) is a transmembrane and non-selective cation channel protein, which can be activated by various physical chemical stimuli. Recent studies have shown the strong pathogenetic associations of TRPV1 with neurodegenerative diseases (NDs), in particular Alzheimer’s disease (AD), Parkinson’s (PD) multiple sclerosis (MS) via regulating neuroinflammation. Therapeutic effects agonists antagonists on treatment AD PD animal models also are emerging. We here summarize current understanding TRPV1’s its as therapeutic means diseases, highlight future strategies using natural agonists. Developing new targets applying products becoming promising direction chronic disorders, especially diseases.

The prevalence rate of allergic rhinitis (AR) is high worldwide. inhalation allergens induces AR, which an immunoglobulin E-mediated and type 2 inflammation-driven disease. Recently, the role neuroimmune communication in AR pathogenesis has piqued interest scientific community. Various neuropeptides, such as substance P (SP), vasoactive intestinal peptide (VIP), calcitonin gene-related (CGRP), nerve growth factor (NGF), neuromedin U (NMU), released via “axon reflexes” or “central sensitization” exert regulatory effects on immune cells to elicit “neurogenic inflammation,” contributes nasal hyperresponsiveness (NHR) AR. Additionally, neuropeptides can be produced cells. frequent colocalization neuronal at certain anatomical regions promotes establishment cell units, nerve-mast cells, nerve-type innate lymphoid (ILC2s), nerve-eosinophils nerve-basophils units. Receptors expressed both neurons, TRPV1, TRPA1, Mas-related G protein-coupled receptor X2 (MRGPRX2) mediate pathogenesis. This review focused elucidating mechanisms underlying

The COVID-19 pandemic has raised concern regarding respiratory system diseases and oral inhalation stands out as an attractive non-invasive route of administration for pulmonary such chronic bronchitis, cystic fibrosis, community-acquired pneumonia. In this context, we encapsulated azithromycin in polycaprolactone nanoparticles functionalized with phospholipids rich dipalmitoylphosphatidylcholine further produced a fine powder formulation by spray drying monohydrated lactose. Nanoparticles obtained the emulsion/solvent diffusion-evaporation technique exhibited mean hydrodynamic diameter around 195–228 nm narrow monomodal size distribution (PdI < 0.2). Nanoparticle dispersions were spray-dried at different inlet temperatures, atomizing air-flow, aspirator air flow, feed rate, using lactose aid, resulting maximal process yield 63% encapsulation efficiency 83%. Excipients dry formulations characterized terms morphology, chemical structure, thermal analyses particle SEM, FTIR, DSC/TGA laser light diffraction. results indicated spherical particles 90% 4.06 µm or below, adequate delivery. Aerosolization performance NGI confirmed good aerodynamic properties. Microbiological assays showed that preserves AZM antimicrobial effect against Staphylococcus aureus Streptococcus pneumoniae strains, halos above 18 mm. addition, no formulation-related cytotoxicity was observed human cell lines BEAS-2B (lung epithelial), HUVEC (endothelial) HFF1 (fibroblasts). Overall, approach described here allows production AZM-PCL incorporated into inhalable microparticles, enabling more efficient therapy lung infections.

Acupuncture has achieved good results in the treatment of cough, asthma, chronic obstructive pulmonary disease (COPD) and other lung diseases, but mechanism associated with acupuncture cough induced by surgery is unknown. We investigated whether therapy could improve symptoms after through cyclic-AMp dependent protein kinase A (PKA)/cyclic-AMp C (PKC) regulation transient receptor potential vanilloid-1 (TRPV1) signaling pathway.The guinea pigs were divided into 5 groups: Sham operation Group (Sham), Model (Model), Electroacupuncture + (EA M), H89 (H89 M) Go6983 (Go6983 M). The effect was determined measuring (number coughs/cough incubation period) as outcome criterion. levels inflammatory cytokines bronchoalveolar lavage fluid (BALF) blood enzyme-linked immunosorbent assays (ELISA).

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory worsening airflow limitation. OBJECTIVE: To explore function rehabilitation, life quality and prognosis in patients with severe COPD. METHODS: Between February 2018 August 2021, 150 COPD cured our hospital were arbitrarily assigned into the control group (n= 75) study 75). The received routine treatment research multidisciplinary diagnosis treatment. body mass index, obstruction, dyspnea exercise (BODE), function, number of acute attacks, 6-minute walking distance (6MWD), Borg score compared. RESULTS: There was no remarkable difference BODE before (P> 0.05). During 2- 6-month following treatment, lower (P< In group, FEV1 percentage predicted value, forced expiratory volume one second (PPO-FEV1) second/forced vital capacity (FEV1/FVC) first higher there fewer attacks After 6MWD scores at 6-months after differences 0.05), however, symptom score, activity influence total CONCLUSION: application model can promote rehabilitation COPD, improve their prognosis, slow down development enhance quality.
