11, 1.99, 4.06, and 8.78 μM, respectively. Their potential interactions were analyzed by molecular docking and molecular dynamics (MD), which suggested that amino acid residues Asp335 and Asn359, especially Gln384, played an important role in the inhibition of compounds 10 and 13 on sEH, and compounds 10 and 13 could be considered as the potential candidates for the development of sEH inhibitors.Oxidized low-density lipoprotein (ox-LDL) not only causes hyperlipidemia and contributes to atherosclerosis but also induces the endothelial dysfunction that leads to cardiovascular diseases. The nuclear factor-kappa B (NF-κB) pathway plays a key role in many chronic disorders and is a transcriptional factor in various inflammatory responses. The present study aimed to investigate the synergistic effects of pelargonic acid vanillylamide (PAVA) and rosuvastatin (RSV) on ox-LDL-induced inflammatory responses in human vascular endothelial cells (HUV-EC-C). HUV-EC-C were pretreated with PAVA or RSV and their combination for 2 h followed by ox-LDL for 24 h. The MTT assay was used to measure mitochondrial function. The DCFH-DA assay was used to evaluate oxidative phosphorylation, and western blotting was used to measured NF-κB/NLRP3 and related signaling pathways in HUV-EC-C. Ox-LDL induced lectin-type oxidized LDL receptor 1 (LOX-1) expression, NADPH oxidase 4 activation, and the overexpression of reactive oxygen species, which were inhibited by pretreatment with the combination of PAVA and RSV. Moreover, PAVA and RSV inhibited ox-LDL-induced NF-κBp65 activation. Ox-LDL induced NF-κB/NLRP3 pathway activation by inducing C-reactive protein expression, NLRP3 activation, caspase-1 activation, and IL-1β secretion, which were inhibited by pretreatment with the combination of PAVA and RSV. The combination of PAVA and RSV reduced ox-LDL-induced recruitment of monocytes to the site of inflammation, inhibited activation of the NLRP3 inflammasome, and ameliorated the impairment of cell-cell junctions through the NF-κB pathway. Our results suggest that the synergistic effects of PAVA and RSV provide a novel mechanism for the treatment of cardiovascular diseases.Verapamil is reported to prevent scar formation. However, whether verapamil is involved in the ureteral stricture scar and the underlying mechanism need further investigation. Fibroblasts were isolated from ureteral scar tissues. TGF-β1 stimulation was used to induce fibrosis of fibroblasts. Inhibition of CaMK II was achieved by shRNA transfection. CCK-8 was performed to evaluate cell viability. qRT-PCR was applied to determine the level of mRNA while western blotting was used to determine the level of proteins. Immunofluorescence was used to detect the level of vimentin, collagen I and collagen III. Primary fibroblasts was successfully isolated from ureteral scar tissues. TGF-β1 stimulation was capable to induce collagen production and fibrosis in primary fibroblasts while inhibition of CaMK II attenuate collagen production. Overexpression of wild type CaMK II lead to further increase of collagen production upon TGF-β1 stimulation while the mutated CaMK II did not exert this promotion. Treatment of verapamil inhibits TGF-β1 induced collagen production via inhibiting CaMK II. In present study, we revealed a vital role of Verapamil and CaMK II in the formation of ureteral scar. Verapamil inhibited TGF-β1 induced collagen fiber formation by regulating CaMK II. Our finding might provide new insight into mechanism of prevention and treatment of ureteral scar.Pyroptosis plays an important role in the pathogenesis of numerous infectious, autoimmune, and inflammatory diseases, which makes it a promising target for intervention. In this study, the effect of luteolin on pyroptosis and the underlying mechanism were investigated using the canonical NLRP3 inflammasome in THP-1 macrophages induced by LPS/ATP. The results showed that luteolin exhibited a potent preventive effect on THP-1 macrophage pyroptosis, as evidenced by the increase in cell viability and the decrease in LDH release. Moreover, luteolin was found to significantly reduce the expression of NLRP3, pro-CASP-1 and CASP-1, which are the key components of NLRP3 inflammasome, as well as the expression of N-GSDMD and IL-1β, and we proved that the inhibition of luteolin on NLRP3 inflammasome activation is ROS-dependent. Furthermore, it was demonstrated that luteolin promoted Nrf2 nuclear translocation, thereby increasing the expression of HO-1 that reduces ROS production, while the anti-pyroptotic effect of luteolin was reversed by a specific Nrf2 inhibitor. Additionally, luteolin inhibited NF-κB p65 phosphorylation and nuclear translocation. In summary, we conclude that luteolin prevents THP-1 macrophage pyroptosis by suppressing ROS production via Nrf2 activation as well as NF-κB inactivation. These results support luteolin as a potential bioactive chemical against pyroptosis-related inflammatory diseases.
The main objective of this study was to assess tolerance of botulinum toxin A injection into the salivary glands under local anesthesia in a pediatric population. Secondary endpoints comprised efficacy and side-effects.

A retrospective observational study included children treated between January 2013 and March 2020 for sialorrhea and/or pharyngeal salivary congestion. Children were identified from the botulinum toxin A injection database. The study included 162 injection sessions in 55 children. Injections were performed under local anesthesia with nitrous oxide, after clinical location of the site. Epidemiological and clinical data, injection tolerance on the FLACC scale, treatment response and complications were recorded.

For submandibular gland injections, pain was absent in 81 cases, mild in 64, moderate in 4 and intense in 1. Selleckchem Bismuth subnitrate In parotid gland injections, pain was absent in 45 cases, mild in 89, moderate in 17 and intense in 1. Injection tolerance was significantly poorer (P<0.005) in parotid than submandibular glands. Seventy-seven percent of the injections had a positive effect on sialorrhea. Fifteen patients presented transient adverse events mainly dysphagia and paradoxical increase in sialorrhea.

Salivary gland botulinum toxin A injections in under local anesthesia were well-tolerated, safe and effective for children with sialorrhea and/or pharyngeal salivary congestion.
