Network Meta-analysis of oral Chinese patent medicine in treatment of knee osteoarthritis / 中国中药杂志

To evaluate the efficacy and safety of Chinese patent medicine in the treatment of knee osteoarthritis(KOA) with network Meta-analysis, and provide evidence-based medicine evidences for clinical practice. PubMed, Cochrane Library, EMbase, CNKI, Wanfang, VIP and CBM were used to search for clinical randomized controlled trials(RCTs) on Chinese patent medicines for treatment of knee osteoarthritis, with a time limit from the establishment of each database to March 2020. The bias risk assessment tool recommended by Cochrane was used to evaluate the quality of the included RCTs. The network Meta-analysis was performed by Stata 14.0 software. A total of 5 788 patients in 58 RCTs were included, involving 9 kinds of Chinese patent medicines. The results of the network Meta-analysis indicated that in terms of total effective rate, the top three optimal medication regimens were Jinwu Gutong Capsules + Amino Acid Glucose(AAG), Xianling Gubao + AAG and Biqi Capsules; the top three interventions to reduce the VAS score were Panlongqi Tablets > Xianling Gubao + AAG > Xianling Gubao + non steroidal anti-inflammatory drugs(NSAIDs); the top three interventions to reduce the total score of WOMAC were Jintiange Capsules+NSAIDs> Jinwu Gutong Capsules + AAG > Biqi Capsules + NSAIDs; the top three medication schemes with better curative effect to reduce Lequesnse index were Xianling Gubao + NSAIDs > Biqi Capsules + NSAIDs > Jintiange Capsules + NSAIDs; the top three interventions to reduce TNF-α level Xianling Gubao + AAG > Jintiange Capsules > Jintiange Capsules + AAG=Jinwu Gutong Capsules + AAG. In terms of safety, the top five interventions with the least adverse reactions were Biqi Capsules > Jinwu Gutong Capsules > Biqi Capsules + NSAIDs > Xianling Gubao + NSAIDs > Jintiange Capsules. The combined application of Chinese patent medicine and NSADIs or AAG can improve the clinical treatment effect and reduce adverse reactions in KOA patients.

Management of bone defects in total knee arthroplasty / 中国组织工程研究

BACKGROUND: Bone defects are one of the most important challenges that surgeons have to manage in total knee arthroplasty. The reasonable treatment method can guarantee the effect of the repair operation. OBJECTIVE: To review the relevant literatures concerning bone defects treated by primary total knee arthroplasty and revision total knee arthroplasty, and to analyze the optimal managements for different types of bone defects. METHODS: Relevant literatures were identified in China National Knowledge Infrastructure, Wanfang data, Vip, PubMed, Medline, and Web of Science. The key words were "total knee arthroplasty, total knee replacement, revision total knee arthroplasty, bone loss, bone defect, bone deficiency, management". The included studies were analyzed and summarized. RESULTS AND CONCLUSION: (1) Sixty-two studies regarding total knee arthroplasty for bone defects were included, without recognized standards on the type of bone defects. AORI is the most widely used classification for bone defects. (2) Pre-operated detailed evaluation including laboratory and radiographic examination, and accurate diagnosis are the key to success. (3) Management of bone defect was similar in tibia and femur, but there is still no standard classification and management of patellar bone defect. (4) Using stem fixation whenever a femoral or tibial component is revised can improve clinical outcome. (5) Through detailed evaluation, accurate diagnose and appropriate classification of bone defect, selection, according to the characteristics of different strategies, the age of the patient and the needs of life, can get a good clinical result.
