BACKGROUND:Platelet-rich plasma (PRP) containing high levels of platelet-derived growth factor for knee osteoarthritis has achieved good clinical results;however, the effects of RPR on the repair of damaged articular cartilage are stil controversial.
OBJECTIVE:To study the effects of RPR on the repair of damaged articular cartilage in a rabbit model of knee osteoarthritis.
METHODS:The model of osteoarthritis in the rabbit right knee was established by Hulth’s method. Autologous PRP (0.5 mL) (PRP group), sodium hyaluronate (0.5 mL) (sodium hyaluronate group), and normal saline (model group) were injected into the right knee joint cavity, respectively. The morphology of articular surface and nitric oxide contents in knee joint fluid were observed and determined at 8 weeks after surgery.
RESULTS AND CONCLUSION:The morphology of articular cartilage in the PRP group was better than that in the other three groups. Mankin scores of articular cartilage and nitric oxide contents of knee joint fluid in the PRP group were significantly decreased compared with the model and sodium hyaluronate groups that in (P<0.05), while increased compared with the sham-operation group (P<0.05). Our results suggest that repair effects of PRP on the damaged articular cartilage are superior to sodium hyaluronate treatment.

The selection of the prosthetic material determine the success or failure of hip arthroplasty. Currently, the metals, ceramics, polymer composites and carbon materials are the main prosthetic materials of artificial hip joint. They have some progresses in biocompatibility, elastic modulus,mechanical properties, useful life, but they still can't reach the ideal standard of design. In this essay, we mainly review the characteristics and applications of the current artificial hip joint materials through its classification in order to provide a reference for choosing appropriate hip joint materials in clinic and increasing characteristic of materials. We consider the polymer composites has more advantages such as biocompatibility, mechanical properties, corrosion resistance and price, even if it has shortages in abrasion resistance. As the researches of polymer composites are main focus on abrasion resistance, articular surface and strength,and its performances are increased fast, it has a wide prospect in future.

Depression is a common emotional disorder that seriously affects people's life and health all over the world. The pathogenesis of depression is complex, and traditional Chinese medicine (TCM) for antidepressants has a good therapeutic effect because of its multi-component, multi-pathway, and multi-target action mode. At present, the anti-depressive mechanism of TCM has not been fully clarified, but it is clear that depression is closely related to metabolic health. Therefore, in order to further explore the anti-depressive mechanism of TCM, this paper proposes research strategies on the anti-depressive mechanism of TCM based on functional metabolomics from the perspective of metabolism, the potential biomarkers of depression are analyzed with the help of multi-omics combined analysis technology, and the functional molecules of TCM for antidepressant are studied. Molecular biology techniques are used to accurately capture the molecular interactions between biomarkers of depression and functional compounds, which identify effective drug targets and further elucidate the biochemical functions and related mechanisms involved in depression metabolic disorders. This paper systematically reviews the research strategies and applications of functional metabolomics in the anti-depressive mechanisms of TCM, expounds on the core value of functional metabolomics, and summarizes the current research status and hot issues of TCM for antidepressants in recent years, providing new methods and new ideas for the study of mechanisms of TCM with the help of functional metabolomics.

Objective To explore the relationship between tumor necrosis factor (TNF) gene polymorphisms in donors and recipients and the incidence and severity of acute graft-versus-host diseases (aGVHD) after unrelated allogeneic hematopoietic stem cell transplantation (alIo-HSCT). Methods Single nucleotide polymorphisms (SNPs) of TNFα-238 (G/A), TNFα-857 (C/T), TNFα-863 (C/A), TNFα-1031 (T/C), TNFβ + 252 (A/G) were analyzed by Multiplex SNaPshot analysis in 76 pairs of donors and recipients. Results Transplantation involving donors with TNFα-857 CC genotype resulted in a higher incidence of grade Ⅱ-Ⅳ aGVHD than donors with CT genotype (91.3% vs 8. 7% , P =0. 039). In the 23 patients with grade Ⅱ-Ⅳ aGVHD, no patients had TNFβ +252 AA genotype, 19 (82.6%) had GA genotype and 4 (17.4%) had GG genotype. There was a significant difference in the distribution pattern of the TNFβ +252 (AA, GA and GG) genotypes in these patients (P =0.03). There was no significant association of TNFα-238 (G/A), TNFα-863 (C/A) and TNFα-1031 (T/C) polymorphisms with the risk of aGVHD. Conclusion These results suggest donor TNFα-857 CC genotype is related to a higher incidence of grade Ⅱ -Ⅳ aGVHD, and patients with TNFβ +252 AA genotype have protection against the risk of grade Ⅱ -Ⅳ aGVHD.

In this paper, the new carbon nanotube modified glassy carbon electrode (F-CNTs/GCE) was prepared to establish a new method for studying the molecular interaction mechanism between baicalin metal complexes (BMC) and bovine serum album (BSA), and the principle of this method was discussed deeply. Under the physiological condition, the thermodynamics and kinetics properties of interaction between BMC and BSA were studied by cyclic voltammetry (CV) to inference their molecular effective mechanism. The results show that the presence of F-CNTs can accelerate the electron transfer, and better response signal was showed in the BMC/BMC-BSA system. The detection of interaction of BMC-BSA used new method show that BMC-BSA generates stable thermodynamically non-covalent compounds, and the obtained average binding sites of BMC-BSA were 1.7; the number of electron transfer in BMC/BMC-BSA reaction process was 2, and non electroactive supramolecular compounds of BMC-BSA were generated by this interacting reaction. The relevant research work provides a new way to study the molecular mechanism for the interaction of drugs with protein, and with a certain reference value for discussion on the non covalent interactions.
