Meta-analysis of the association of IL1-RN variable number of tandem repeats polymorphism with osteoarthritis risk.

Objective: The aim of this meta-analysis was to clarify the role of Interleukin-1 receptor antagonist gene (IL1-RN) Variable Number of Tandem Repeats (VNTR) polymorphism on the risk of OA by means of meta-analysis.

Methods: Eligible articles were retrieved from PubMed, Web of science and Google scholar with a total of 1187 OA cases and 2659 controls. The strength of the association between the IL1-RN VNTR polymorphism and the risk of OA was assessed by odds ratios (ORs) with the corresponding 95% confidence interval (CI) for each study.

[Distal Chevron osteotomy of the first metatarsal and soft-tissue release for hallux valgus].

Objective: To explore distal Chevron osteotomy of the first metatarsal and soft-tissue release for the treatment of mild and moderate hallux valgus.

Methods: From June 2015 to June 2017, 32 patients(40 feet) with mild and moderate hallux valgus were treated with distal Chevron osteotomy with soft tissue release. including 3 males(3 feet) and 29 females (37 feet), aged from 22 to 80 years old with an average of 57.

Effects of MMP-1 1G/2G polymorphism on osteoarthritis: A meta-analysis study.

Objective: The aim of this meta-analysis was to clarify the role of Matrix metalloproteinase 1 (MMP-1) -1607 1G/2G (rs1799750) polymorphism on the osteoarthritis (OA) risk.

Methods: Articles were selected by retrieving the Web of Science, Embase and Pubmed. The strength of the association between -1607 1G/2G polymorphism and OA risk was assessed by odds ratios (ORs) with the corresponding 95% confidence interval (CI) for each study.

NLRP1 and NLRP3 inflammasomes mediate LPS/ATP‑induced pyroptosis in knee osteoarthritis.

Pyroptosis is triggered by inflammasomes after its activation by various inflammatory stimulations, including lipopolysaccharide (LPS) and improper pH. This may result in programmed death of the affected cell. It is well known that NLRP1 and NLRP3 inflammasomes mediate the production of various cytokines in inflammatory disorders; however, it is still unknown whether NLRP1 and NLRP3 inflammasomes can influence the LPS‑induced pyroptosis in the progression of knee osteoarthritis (KOA).
