The NLRP3 inflammasome (i.e., NLRP3, ASC, caspase-1) was not affected by individual stimulation using P. gingivalis-LPS or hypoxia. However, the combination of both hypoxia and P. gingivalis-LPS stimulation significantly enhanced inflammasome activation and promoted the expression of interleukin-1β, gasdermin D and HIF-1α at gene and protein levels; PI positive cells and the release of LDH were also elevated.

Hypoxia and P. gingivalis-LPS synergistically induced NLRP3 inflammasome activation in HGFs, and subsequently high levels of interleukin-1β and GSDMD-mediated pyroptosis can cause an HGF inflammatory response, which plays an important role in the pathogenesis of periodontitis.

Subcutaneous implants of heat-coagulated egg white (egg white implants, EWI) induce intense local eosinophilia and prime for hyperreactivity following airway ovalbumin challenge. The roles of allergen sensitization, surgical trauma-induced glucocorticoids, and the 5-lipoxygenase (5-LO) pathway were hitherto unexplored in this model, in which quantitative recovery and large-scale purification of the eosinophils from the inflammatory site for functional and immunopharmacological studies are difficult to achieve.

We overcame this limitation by shifting the implantation site to the peritoneal cavity (EWIp), thereby enabling quantitative leukocyte retrieval.

By day 7 post-surgery, eosinophil counts reached~30% of all leukocytes recovered. AZD9291 datasheet Eosinophilia was prevented by a) induction of allergen-specific oral tolerance to ovalbumin, the main allergen in egg white; b) inactivation of the 5-lipoxygenase pathway; c) blockade of endogenous glucocorticoid signaling by pretreatment with metirapone plus mifepristone bt source of pure, nontransgenic eosinophils for immunopharmacological studies.

The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are associated with the severity of Henoch-Schonlein purpura (HSP). Therefore, we conducted a meta-analysis to evaluate the clinical significance of NLR and PLR in HSP and its complications.

A comprehensive literature search was conducted by searching the PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang, VIP, and SinoMed databases from their inception to September 31, 2020. We used the standard mean difference (SMD) with a 95% confidence interval (CI) to estimate the pooled effect and used subgroup analysis to investigate heterogeneity.

A total of 1,691 HSP patients and 563 healthy controls (HCs) from 15 studies were included in the analysis. The NLR value was significantly higher in 431 HSP patients with gastrointestinal complications (HSP-GCs) than that in 833 HSP patients without GCs (SMD=1.09, 95% CI 0.62-1.57, P<0.001); in 83 HSP adult patients with renal involvement (HSP-RI) than that in 131 adult HSP patients without RI (SMD=0.33, 95% CI 0.05-0.60, P=0.021); and in 831 HSP patients than that in 563 HCs (SMD=0.70, 95% CI 0.51-0.89, P<0.001). The PLR was significantly higher in 417 HSP patients than that in 264 HCs (SMD=0.39, 95% CI 0.06-0.71, P = 0.02).

NLR could serve as a useful biomarker to predict GCs and RI in patients with HSP. However, further well-designed and large cohort studies are warranted to confirm these findings.

Negative life events have been reported as a risk factor for elderly self-harm. The aim of this study was to examine the relationship between negative life events and self-harm in a large sample of people aged 60 and older, and explore the role of some previously identified influential factors in this relationship.

Multi-stage stratified sampling method was used to select the elderly people over 60 years old in Shandong, China. Information were collected through face-to-face interviews. Univariate and multivariable logistic regression were used for initial analysis. Karlson-Holm-Breen (KHB) method was used for mediating effect analysis.

A total of 7070 participants were included in the study, 160 reported they had a history of self-harm (2.3%), 756 reported they had negative life event experience (10.7%). After model adjustment, the association between negative life events, loneliness, economic status and self-harm was still statistically significant. Mediation analysis showed that the association is explained by loneliness (proportion of mediation 48.86%), self-rated economic status (16.13%).

Negative life events, loneliness and economic status were associated with self-harm among the older adults. Loneliness and economic status may play an intermediary role in the relationship between negative life events and self-harm, especially loneliness. More psychological and social functions intervention strategies and prevention measures on the self-harm of the elderly should be provided for the elderly who have experienced negative life events.

The high cost of activators, and energy input, as well as the expense to separate the catalyst and transition metal reducing agent from the treated soil, were some disadvantages of using activated PMS. Based on the above rationales of problems related to the use of activated PMS, this study aimed to study the performance of using unactivated peroxymonosulfate for the advanced oxidation process to remediate soil contaminated by trichloroethylene (TCE), and to evaluate the synergistic effect on selected soil properties after treatment. The results showed that within 45 min, a single injection of 5 mM PMS at its initial pH value can degrade 86.90% of the total TCE in the soil. However, when PMS was continuously injected, the removal rate was increased to 95.25%. The direct reaction of TCE and PMS was the main cause of degradation.
