OBJECTIVE@#To explore clinical effect of the first metatarsophalangeal joint fusion combined with lateral toe rotation Weil osteotomy in treating hallux valgus with severe metatarsal adduction.@*METHODS@#From March 2017 to August 2021, 37 patients ( 69 feet ) with severe plantar adductor hallux valgus were treated with the first metatarsophalangeal joint fusion combined with rotational Weil osteotomy were retrospectively analyzed, including 8 males(11 feet) and 29 females (58 feet), aged from 67 to 83 years old with an average of (70.03±2.87) years old;3 cases on the left side, 2 cases on the right side and 32 cases on both sides. Visual analogue scale(VAS) was used to evaluate degree of pain relief before operation, 6 weeks after operation and at the final follow-up. American Orthopaedic Foot and Ankle Surgery (AOFAS) forefoot score was used to evaluate function of the affected foot before operation and final follow-up. Hallux valgus angle(HVA) and intermetatarsal angle(IMA) were measured before operation and at the final follow-up.@*RESULTS@#Thirty-seven patients(69 feet) were followed up from 12 to 48 months with an average of(22.8±0.6) months. Bone healing was achieved at the first metatarsophalangeal joint from 7 to 10 weeks with an average of (8.00±1.21) weeks after operation, without delay and nonunion. HVA was increased from (44.30±2.84)° before operation to (15.20±2.13) °at the final follow-up, and had statistical difference(t=65.781, P<0.05);while no difference in IMA before and after operation(P>0.05). VAS was decreased from (6.73±1.48) points to (2.78±0.71) points at 6 months after operation(t=3.279, P<0.05), and had difference compared with the latest follow-up(1.16±1.12)(t=4.859, P<0.05). AOFAS forefoot score increased from (52.14±5.78) preoperatively to (86.70±4.86) at the fonal follow-up, and 25 feet got excellent results, 40 feet good and 4 feet fair.@*CONCLUSION@#The first metatarsophalangeal joint fusion combined with lateral toe rotation Weil osteotomy in treating severe plantar adduction hallux valgus could significantly relieve pain and appearance of forefoot, stabilize the first sequence, and significantly improve walking function.

Effect of (, TLZT) gel preparation on p53 /miR-502-5p /NF-κBp65 in synovial tissue of knee osteoarthritis / 中国骨伤

OBJECTIVE@#To observe effects of (, TLZT) gel preparation on p53, miR-502-5p, NF-κBp65 in synovial tissue of knee osteoarthritis (KOA), and to explore mechanism of TLZT gel preparation in treating KOA.@*METHODS@#Thirthy-six Wistar rats aged 8 weeks and weighed 200 to 220 g (meaned 208 g) were randomly divided into normal group, model group and traditional Chinese medicine (TCM) group, 12 rats in each group. KOA model was established by modified Hulth method. After 4 weeks of modeling, TCM group treated with TLZT gel preparation for external use, 3 times daily for 2 weeks;normal group and model group were fed normally without intervention. After treatment, morphological changes of specimens in each group were observed, changes of miR-502-5p in synovial tissue were detected by qPCR, and contents of p53, NF-κBp65, IL-1β, TNF-α, MMP-13 in synovial tissue were detected by qPCR and Western Blot respectively.@*RESULTS@#(1)Morphological observation of specimens showed that the articular cartilage in model group was hyaline and uneven, the synovial membranes were hypertrophic and proliferative with a large number of inflammatory cells infiltrating, the joint fluid was thicker in texture;the articular cartilage in TCM group was more transparent and smooth, synovial hyperplasia was mild with a small amount of inflammatory cell infiltration, the texture of articular fluid was clear and sparse. (2) Compared with normal group, content of miR-502-5p of synovial tissue in model and TCM group were increased, mRNA and expression of p53 decreased, expression of NF-κBp65, IL-1β, TNF-α, MMP-13 increased. (3)Compared with model group, content of miR-502-5p in synovial tissue of TCM group decreased (<0.05), mRNA and protein expression of p53 increased (<0.05), mRNA and protein expression of NF-κBp65, IL-1β, TNF-α, MMP-13 decreased (<0.05).@*CONCLUSION@#Expression of p53, miR-502 -5p, NF -κBp65 in synovial tissue is closely related to synovial hyperplasia and inflammatory reaction, TLZT gel preparation may reduce proliferation and inflammatory reaction of KOA synovium by regulating the expression of p53, miR- 502-5p, NF-κBp65 in synovial tissues.

OBJECTIVE@#To investigate the clinical effect of Lapidus operation combined with bone setting manipulation of traditional Chinese medicine in treating hallux valgus in elderly patients.@*METHODS@#From March 2013 to October 2017, 53 elderly patients (87 feet) with hallux valgus were treated with Lapidus operation combined with bone-setting manipulation of traditional Chinese medicine, including 12 males (18 feet) and 41 females (69 feet), ranging in age from 65 to 92 years old, with an average of (76.3±4.8) years old. Visual analogue scale(VAS) was used to evaluate the degree of relief of foot pain before and 26 months after operation. American Orthopaedic Foot and Ankle Society(AOFAS) was used to evaluate the function of foot pain. The changes of hallux valgus angle(HVA angle), interphalangeal angle (IMA angle) and metatarsal wedge angle(MCA angle) were compared on X-ray films.@*RESULTS@#All the patients were followed up, and the duration ranged from 12 to 42 months, with an average of(26.0±2.7) months. In all patients, the first metatarsal joint reached bone fusion within 6 to 8 months, with an average of 4.7 months. The preoperative VAS score was 8.06±1.44, which was significantly different from 2.14±1.98 at 26 months(<0.05). The preoperative AOFAS score was 53.90±7.89, which was significantly different from 92.80±2.78 at 26 months(<0.05). The HVA, IMA and MCA were significantly improved from preoperative(38.60±2.72)°, (21.90±1.91)° and(20.90±2.20)° to the latest follow-up(17.80±1.94)°, (9.70±2.56)° and(11.70±0.48)°(<0.05). According AOFAS score, 74 feet got an excellent result, 11 good and 2 fair.@*CONCLUSIONS@#Lapidus operation combined with bone-setting manipulation of traditional Chinese medicine on the treatment of hallux valgus foot in elderly patients has satisfactory clinical effects, shortens the time of osteotomy and fixation, protects the soft tissue around the osteotomy end and promotes the bone fusion on the most satisfactory position.

Progress on establishment of animal model of osteoarthritis by intra-articular injection / 中国骨伤

Osteoarthritis (Osteoarthritis, OA) is a common clinical degenerative joint disease with increased incidence rate in recent years. Animal experiment is one of the important ways to explore pathogenesis and treatment of OA, while induced animal model is the most important part in animal experiment. Intra-articular injection of drugs is a classical method for establishing animal model of OA. Choose of animal should follows the principle of correlation, appropriateness and practicability, injections should perform in accordance with experimental purposes and subject, detections means and evaluation methods also should corresponding to experimental reality. The gold standard of OA animal model and intra-articular injections has not build, need further study.
