RESUMO
Osteoarthritis （OA） is a common chronic， highly prevalent， painful， and disabling degenerative joint disease. It has imposed a heavy burden on social healthcare and patients' psychology and economy due to its clinical symptoms such as impaired joint mobility and severe joint pain and the immature therapies. Studies have shown that OA is closely associated with articular cartilage dysfunction， synthesis and degradation disorders of chondrocyte extracellular matrix （ECM）， and joint inflammation. Moderate autophagy can restore the function of damaged chondrocytes， regulate chondrocyte apoptosis， and promote the synthesis and metabolism of ECM to alleviate the inflammation of joints and delay the onset and progression of OA. According to the clinical symptoms， OA can be classified into the category of impediment in traditional Chinese medicine. With the theories of holistic conception， treatment based on syndrome differentiation， and individualised diagnosis and treatment， traditional Chinese medicine has demonstrated definite effects in the treatment of OA in thousands of years of practice. Moreover， traditional Chinese medicine causes mild adverse reactions， and the patients have high tolerance and acceptance. This paper briefly explains the roles of autophagy and the related regulatory proteins， such as Unc-51-like autophagy-activated kinase 1 （ULK1）， Beclin-1， and microtubule-associated protein light chain 3 （LC3）， and details the latest research achievements in the prevention and control of OA by traditional Chinese medicines and its related markers via the regulation of autophagy， so as to provide a idea for the in-depth research in this field and the clinical application of traditional Chinese medicine in preventing and treating OA.
RESUMO
Objective To compare and evaluate the methods of building model of cervical spondylosis of vertebral artery type (CSA)rats by measuring the learning and memory ability,anxiety and depression,and degree of nervous tension of three kinds of CSA model rats.Methods We randomly divided 120 rats into mixed modeling group,bone graft compression modeling group,mechanical balance disorder modeling group,and blank control group with 30 rats in each.Morris water maze,elevated plus maze test and open field test were used to detect and compare the rats’abilities of learning and memory,anxiety and depression,and degree of nervous tension.We then evaluated the three CSA rat models.Results Compared with those in the blank group,the learning and memory abilities in the mixed modeling, bone graft compression and mechanical balance disorder modeling rats were significantly decreased,the anxiety and depression and degree of nervous tension were significantly increased (P<0.05).Compared with bone graft compression and mechanical balance disorder modeling groups,the mixed modeling group could restore the characteristics of CSA.Conclusion The three kinds of modeling methods can successfully reproduce the CSA animal model;the mixed modeling is superior and thus worthy of promotion.
RESUMO
Objective To observe the clinical effects of Huoxue Dingxuan Capsules on treatment of vertebral artery type of cervical spondylosis, and evaluate its efficacy and safety. Methods Totally 130 cases of vertebral artery type of cervical spondylosis were randomly assigned to treatment group and control group, and treated with Huoxue Dingxuan Capsules and Sibelium capsules respectively. Integration method was used to compare the differences of main symptoms and signs, the overall efficacy and safety were evaluated, and relapse after six months was followed up. Results Both groups had a significant effect on the improvement of signs and symptoms in vertebral artery type of cervical spondylosis, the total efficiency was 94.03%(63/67) in treatment group and 82.54% (52/63) in control group. The treatment group had a better effect on the overall efficacy and relieving symptoms and signs compared with the control group (P<0.01). The mean blood flow velocity had a significant change after treatment (P<0.05), and the treatment group was better than the control group (P<0.01). Within six months, the treatment group had 4 cases (6.34%) with mild recurrence of symptoms and signs, and the control group had 18 cases (34.61%), the difference between the two groups was statistically significant (P<0.05), and no severe recurrence was found. The two groups showed no side effects. Conclusion Huoxue Dingxuan Capsules is safe and effective for treating vertebral artery type of cervical spondylosis, and the long-term efficacy and subjects’ compliance are better than oral Sibelium capsules.
RESUMO
BACKGROUND:The V-ATPase a3 transport system plays a crucial role on bone resorption mechanism of the osteoclasts. OBJECTIVE:To observe the expression of V-ATPase a3 transport system in fracture repair and the effect of V-ATPase a3 transport system inhibitor on fracture healing. METHODS:We retrieved related literatures in the periodicals database with the key words, and screen them according to the inclusion criteria. The literatures were included in this study after the evaluation of quality. RESULTS AND CONCLUSION:V-ATPase a3 transport system widely exists in the cytoplasm membrane and organel e membrane of eukaryotic cells. V-ATPase a3 has two structural domains:V0 and V1. V0 structural domain is the proton transport channel, V1 structural domain is mainly the hydrolysis of ATP. V-ATPase a3 transport system focuses on the fril ed edge of osteoclasts, H+is transported to form a high concentration, dissolves inorganic minerals and provides the acidic environment for hydrolytic enzymes, thus being involved in bone resorption. So V-ATPase a3 transport system is selected as the research target in the fracture repair and reshape.
