ABSTRACT
Osteoarthritis(OA) is a common clinical disease. The incidence of OA increases significantly with age, and the quality of life of patients is seriously affected. In the pathogenesis of OA, cartilage degeneration is the main cause. There are many long non-coding RNA (lncRNA) specifically expressed in osteoarthritis, which is closely related to the occurrence and development of osteoarthritis. Based on the latest research from 2014 to 2019, this paper summarizes the differential expression of lncRNA in osteoarthritis, the mechanism of lncRNA regulating chondrocyte function, and the mechanism of lncRNA regulating cartilage matrix metabolism. The fact that the expression of lncRNA is altered at different stages of OA development indicates that lncRNA can be developed forlife. The biomarkers and therapeutic targets can provide reference for the prevention, treatment and research of osteoarthritis.

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 57.57 years old. The courses of disease ranged from 2 to 32 years with an average of 14 years. Among them, 9 feet were mild, 31 feet were moderate. Patients were combined with bunion, pain around the first metatarsal joint, and pain increased during weight-bearing walking before opertaion. AP and lateral X-rays on weight-bearing were performed, hallux valgus angle(HVA) and intermetatarsal angle(IMA) between the first and the second metatarsal were examined before and after operation. AOFAS score was applied to evaluate clinical effects.@*RESULTS@#All patients were followed up from 12 to 24 months with an average of 15.2 months.Fracture wounds were healed well without infection and metatarsal head necrosis occurred. Preoperative HVA (32.08±5.59)° and IMA (11.63±2.24)° decreased to (10.31±4.36)° and (5.02°±2.34)°after operation at 12 months, and had statistical difference before and after operation (<0.05). AOFAS score increased from 56.75±6.42 before operation to 88.80±3.99 after operation at 12 months(<0.05).@*CONCLUSIONS@#Distal Chevron osteotomy of the first metatarsal and soft-tissue release for the treatment of mild and moderate hallux valgus could obtain good effects and provide more options for hallux valgus treatment.
