Methods The relevant literary works concerning the articular cartilage, subchondral bone, and crosstalk between them in OA and non-OA states by Wnt signaling pathway in vivo and vitro experimental studies and clinical researches in recent years ended up being evaluated, while the system had been examined and summarized. Results Wnt signaling can control the differentiation and function of chondrocytes and osteoblasts through the classic β-catenin-dependent or non-classical β-catenin-independent Wnt signaling pathway and its particular cross-linking with other signaling pathways, thereby impacting the cartilage and bone metabolic process. Moreover, Wnt signaling path can activate the downstream necessary protein mi-rna Wnt1-inducible-signaling path protein 1 to manage the progress of OA and it also may be set up space junctions between different cells in cartilage and subchondral bone to communicate particles directly to manage OA occurrence and development. Intra-articular injection of Wnt signaling inhibitor SM04690 can inhibit the development of OA, and overexpression of Wnt signaling path inhibitor Dickkopf in osteoblasts can antagonize the role of vascular endothelial growth element work with chondrocytes and inhibit the catabolism of their matrix. Conclusion The legislation of metabolic process and function of cartilage and subchondral bone and crosstalk between them is by interactions among Wnt signaling pathway and particles of other signaling. Consequently, it plays an vital part when you look at the event and growth of OA and is anticipated to become a fresh target of OA treatment through intervention and legislation of Wnt signaling pathway.Objective To summarize the development in treatment of unstable atlas break, the current problems, additionally the analysis direction. Practices associated literature at home and overseas had been reviewed. The security evaluation of atlas fracture and treatment methods were introduced, additionally the variety of surgical method and fixation devices in treatment of volatile atlas fracture were summarized and reviewed. Outcomes At present, atlas cracks are thought as unstable cracks except solitary anterior arch cracks with full transverse ligament or easy posterior arch fractures. The treatment of unstable atlas fracture is created from nonsurgical therapy and traditional fusion surgery to single-segment fixation. Nonsurgical treatment is less efficient, while conventional fusion surgery has a disadvantage of limited the motion associated with top cervical back. Single-segment fixation can not only restore and fix the fracture, but additionally preserve the upper cervical movement function. Single-segment fixation methods include posterior and transoral approaches, therefore the fixation tools are being continuously improved, mainly including screw-rod system, screw-plate system, and plate system. Conclusion For unstable atlas fracture, single-segment fixation is a perfect medical method, and it has more benefits when put next with nonsurgical therapy and traditional fusion surgery. Single-segment fixation via transoral approach is more direct for atlas anterior arch fracture reduction, but there is however a high threat of infection; and single-segment fixation via posterior strategy is less efficient when it comes to decrease in atlas anterior arch fracture. Therefore, an improved decrease method ought to be explored.Objective In summary the study development of killer turn in posterior cruciate ligament (PCL) reconstruction. Techniques The literature pertaining to the killer change in PCL repair in the last few years was looked and summarized. Results The present research has revealed that the killer turn is recognized as becoming more important reason for graft relaxation after PCL reconstruction. In center, this impact is reduced by changing the fixation mode of bone tunnel, switching the orientation of bone tunnel, squeezing screw fixation, maintaining the remnant, and grinding the bone at the exit of bone tunnel. But there is however nevertheless a lack of long-lasting followup. Summary you may still find lots of controversies on the enhanced strategies associated with killer turn. More in depth fundamental researches focusing on biomechanics to help explore the process of this reconstructed graft abrasion are required.Objective To investigate the consequence of micro RNA (miR)-335-5p managing bone morphogenetic protein 2 (BMP-2) on the osteogenic differentiation of real human bone tissue marrow mesenchymal stem cells (hBMSCs). Methods hBMSCs were cultured in vitro and randomly split into control team (group A), miR-335-5p imitates group (group B), miR-335-5p mimics negative control team (group C), miR-335-5p inhibitor group (group D), and miR-335-5p inhibitor negative control group (group E). After grouping therapy and induction of osteogenic differentiation, the osteogenic differentiation of cells in each team ended up being recognized by alkaline phosphatase (ALP) and alizarin red staining; the expressions of miR-335-5p and BMP-2, Runt-related transcription factor 2 (Runx2), osteopontin (OPN), and osteocalcin (OCN) mRNAs were detected by real time fluorescence quantitative PCR analysis; the expressions of Runx2, OPN, OCN, and BMP-2 proteins were recognized by west blot. Results compared to group A, the relative proportion of ALP positive cells together with relative content of mineralized nodules, the relative expressions of BMP-2, miR-335-5p, OPN, OCN, Runx2 mRNAs, the general expressions of Runx2, OPN, OCN, and BMP-2 proteins in group B had been somewhat increased ( P0.05). Conclusion miR-335-5p can up-regulate BMP-2 appearance and advertise osteogenic differentiation of hBMSCs.Objective To explore the effectiveness of liposuction strategy assisted superomedial pedicle with a vertical incision in decrease mammaplasty. Methods Between March 2014 and March 2019, 65 patients (127 edges) with breast hypertrophy had undergone breast reduction by using liposuction method assisted superomedial pedicle with a vertical cut.
