Abstract
Interleukin-6 (IL6) is encoded by the IL6 gene in human and acts as pro-inflammatory cytokine and an anti-inflammatory cytokine. Recent studies established that IL6 substantially contribute in the diagnosed of systemic inflammation for the patients suffering from lung diseases such as chronic obstructive pulmonary disease (COPD). Thereof, this work aimed to investigate the protagonist of IL6 (-174 G/C) genotypes as an essential risk factor for COPD in north Indian population. In the study, a total of 200 clinically diagnosed patients with COPD were selected against 200 patients. Statistical analysis reveleaed that there was no significant association between the IL6 -174 G/C genetic polymorphism and the risk of COPD (P>0.05).

Abstract
Glaesserella parasuis(G. parasuis) causes porcine vascular inflammation and damage. Baicalin is reported to have antioxidant and anti-inflammatory functions. However, whether baicalin protects piglets againstG. parasuischallenge and the potential protective mechanism have not been investigated. Therefore, in this study, we comprehensively examined the protective efficacy of baicalin in piglets challenged withG. parasuisand the possible protective mechanism. Our results show that baicalin attenuated the release of the inflammation-related cytokines interleukin (IL) 1 beta, IL6, IL8, IL10, and tumour necrosis factor alpha (TNF-alpha) and reduced high mobility group box 1 (HMGB1) production and cell apoptosis in piglets infected withG. parasuis. Baicalin also inhibited the activation of the mitogen-activated protein kinase (MAPK) signalling pathway and protected piglets againstG. parasuischallenge. Taken together, our data suggest that baicalin could protect piglets fromG. parasuisby reducing HMGB1 release, attenuating cell apoptosis, and inhibiting MAPK signalling activation, thereby alleviating the inflammatory response induced by the bacteria. Our results suggest that baicalin has utility as a novel therapeutic drug to controlG. parasuisinfection.
