[PMID: 34863307 PMCID: PMC8643019 DOI: 10.1186/s13223-021-00620-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Accepted: 11/01/2021] [Indexed: 11/10/2022] Open
Abstract
Background This study was designed to investigate the mechanism and effects of miRNA-221-5p on the T-helper 17 (Th17)/T-regulatory (Treg) ratio in asthma. Methods BALB/c mice were intranasally challenged with 100 µg OVA on 14 and 21 day. Mice were rechallenged with 2.5% OVA-PBS on 22 and 28 day. Mice were sacrificed using on day 30 under 35 mg/kg pentobarbital sodium. PBMCs were induced vitro model of asthma using 500 ng of lipopolysaccharides (LPS) for 4 h. Results The expression of miRNA-221-5p was reduced in in vivo model, compared sham group. The vitro model of asthma treated with miRNA-221-5p mimic resulted in the reduction of IL-6, IL-17, IL-21 and IL-22 levels, and induction of IL-10, IL-35 and TGF-β levels. In addition, down-regulation of miRNA-221-5p induced the protein expression of suppressor of cytokine signaling 1 (SOCS1) and receptor-related orphan receptor-gamma-t (RORγt) and suppressed that of FOXP3 in in vitro model of asthma. Over-expression of miRNA-221-5p induced the protein expression of FOXP3, and suppressed that of SOCS1 and RORγt in in vitro model of asthma. The inhibition of SOCS1 or RORγt attenuated the effects of anti-miRNA-221-5p on Th17/Treg ratio in asthma. Conclusion miRNA-221-5p may play critical roles in driving the differentiation of Th17/Treg ratio via RORγt/Foxp3 by Targeting SOCS1, reduced the function of Th17 cells by directly inhibiting RORγt/SOCS1 and promoted the function of Treg cells via Foxp3/ SOCS1 in asthma.

Quercetin protects against inflammation, MMP‑2 activation and apoptosis induction in rat model of cardiopulmonary resuscitation through modulating Bmi‑1 expression. Mol Med Rep 2018; 18:610-616.

Abstract
With extensive pharmacological actions, quercetin has anti‑oxidant, free radical scavenging, anti‑tumor, anti‑inflammatory, anti‑bacterial and anti‑viral activity. Quercetin also reduces blood glucose and reduces high blood pressure, and has immunoregulation and cardiovascular protection functions. Additionally, it has been reported that it can reduce depression. The current study evaluated whether quercetin protects against inflammation, matrix metalloproteinase‑2 (MMP‑2) activation and apoptosis induction in a rat model of cardiopulmonary resuscitation (CPR), and whether Bmi‑1 expression was involved in the effects. In CPR model rats, treatment with quercetin significantly recovered left ventricular ejection fraction, left ventricular fractional shortening, ejection fraction (%), and left ventricle weight/body weight. Treatment with quercetin significantly inhibited ROS generation, inflammation and MMP‑2 protein expression in the rat model CPR. Finally, quercetin significantly suppressed caspase‑3 activity and activated Bmi‑1 protein expression in the rat model of CPR. The results demonstrated that quercetin protects against inflammation, MMP‑2 activation and apoptosis induction in a rat model of CPR, and that this may be mediated by modulating Bmi‑1 expression.

Abstract
In a course of development and preparation of landiolol (1a), a known ultra-short-acting β-blocker, process quality control by HPLC and LC-MS analysis consistently showed an impurity peak ranging from 0.05% to 0.15 % and exhibiting a molecular mass m/z 887. To identify the hitherto unknown impurity, we prepared one of the possible landiolol derivatives with the same molecular mass for proper spectral characterization (NMR and MS). Its equivalence with the unknown impurity was then confirmed by LC-MS analysis. Ultimately, using fragmentation patterns in LC-MS and selective two-dimensional NMR experiments, the structure of the impurity was assigned as [(4S)-2,2-dimethyl-1,3-dioxolan-4-yl]methyl 3-{4-[(2S)-2-hydroxy-3-(3-{4-[(2S)-2-hydroxy-3-[(2-{[(morpholin-4-yl)carbonyl]amino}ethyl)amino]propoxy]phenyl}-N-(2-{[(morpholin-4-yl)carbonyl]amino}ethyl)propanamido)propoxy]phenyl}propanoate (2). It was found that the impurity was present in two rotameric forms at room temperature. The synthesis and NMR characterization of (2) are discussed.

The role of catecholamines in the pathogenesis of neurogenic pulmonary edema associated with subarachnoid hemorrhage. Acta Neurochir (Wien) 2012; 154:2179-84; discussion 2184-5. [PMID: 23053288 DOI: 10.1007/s00701-012-1515-x] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2012] [Accepted: 09/25/2012] [Indexed: 10/27/2022]
Abstract
BACKGROUND Neurogenic pulmonary edema (NPE) occurs frequently after aneurysmal subarachnoid hemorrhage (SAH), and excessive release of catecholamines (epinephrine/norepinephrine) has been suggested as its principal cause. The objective of this retrospective study is to evaluate the relative contribution of each catecholamine in the pathogenesis of NPE associated with SAH. METHODS Records of 63 SAH patients (20 men/43 women) whose plasma catecholamine levels were measured within 48 h of SAH onset were reviewed, and the clinical characteristics and laboratory data of those who developed early-onset NPE were analyzed thoroughly. RESULTS Seven patients (11 %) were diagnosed with NPE on admission. Demographic comparison revealed that the NPE+ group sustained more severe SAH than the NPE- group. Cardiac dysfunction was also significantly more profound in the former, and the great majority of the NPE+ group sustained concomitant cardiac wall motion abnormality. There was no significant difference in the plasma epinephrine levels between NPE+ and NPE- group (324.6 ± 172.8 vs 163.1 ± 257.2 pg/ml, p = 0.11). By contrast, plasma norepinephrine levels were significantly higher in the NPE+ group (2977.6 ± 2034.5 vs 847.9 ± 535.6 pg/ml, p < 0.001). Multivariate regression analysis revealed that increased norepinephrine levels were associated with NPE (OR, 1.003; 95 % CI, 1.002-1.007). Plasma epinephrine and norepinephrine levels were positively correlated (R = 0.48, p < 0.001). According to receiver operating characteristic curve analysis, the threshold value for plasma norepinephrine predictive of NPE was 2,000 pg/ml, with an area under the curve value of 0.85. CONCLUSIONS Elevated plasma norepinephrine may have more active role in the pathogenesis of SAH-induced NPE compared with epinephrine, although both catecholamines may be involved via multiple signaling pathways.

Abstract
A method for the determination of landiolol, an ultra-short-acting β₁-adrenoreceptor antagonist, in human plasma has been developed and validated. With the addition of pyridostigmine bromide to stabilize landiolol in the blood/plasma samples, and bisoprolol as internal standard, plasma samples were subjected to liquid-liquid extraction with diethyl ether:dicholoromethane (60:40, v/v) prior to assay by liquid chromatography-tandem mass spectrometry. Separation was performed on a TC-C₁₈ column (150 mm × 4.6 mm, 5 μm) using a mobile phase of methanol:10 mM ammonium acetate containing 1% formic acid (65:35, v/v) in a run time of 3.5 min. Detection involved electrospray ionization in the positive ion mode followed by multiple reaction monitoring of the precursor-to-product ion transitions of landiolol at m/z 510.1→157.2 and bisoprolol at m/z 326.3→116.1. The method was linear over the concentration range 0.5-500 ng/ml with a lower limit of quantitation of 0.5 ng/ml. Intra- and inter-day precisions (as relative standard deviation, RSD) were <4.4% and <10.0%, respectively, with accuracy (as relative error, RE) <10.0%. The method was successfully applied to a clinical pharmacokinetic study involving a continuous infusion of landiolol hydrochloride to healthy Chinese volunteers.
