ABSTRACT
Objective To observe the clinical effect of Jiawei Gegen Decoction on cervical spondylosis of sympathetic.Methods 54 patients with cervical spondylosis from June 2013 to June 2016 were divided into the control group and the study group by odd and even numbers,each 27 cases,the contrel group was treated with Flunarizine Hydrochloride, the study group was treated with Jiawei Gegen decoction,The treatment effect, symptom improvement and adverse reaction rate were evaluated between the two groups.Results Compared with the control group, the treatment effect of the patients in the study group and the improvement of symptoms after treatment were better than the control group,the incidence of adverse reactions was lower in the study group (P <0.05).Conclusion With Jiawei Gegen Decoction for the treatment of sympathetic cervical spondylosis patients, the treatment effect is prominent, at the same time, the symptoms of patients improved better, less adverse reactions, it is worthy of clinical trust.
ABSTRACT
BACKGROUND:So far, the pathogenesis of discogenic low back pain is poorly understood. A great diversity of therapeutic means is developed for discogenic low back pain, but the therapeutic outcomes are mixed. OBJECTIVE:To review the research progress in mechanisms and repair of intervertebral disc degeneration in recent years. METHODS: The first author retrieved the PubMed and CNKI databases for relevant articles published before November 2014 using the keywords of “disc degeneration factor, discogenic low back pain, disc degeneration therapy” in English and Chinese, respectively. Initialy, 78 relevant articles were retrieved, but only 30 articles were included in result analysis folowing elimination of duplicate studies. RESULTS AND CONCLUSION:The relatively respected factors for intervertebral disc degeneration include changes in morphology, inflammatory neurotransmitters and the extracelular matrix as wel as role of growth factors. The treatment for intervertebral disc degeneration stil focuses on the morphological restoration. Some surgical therapies, including percutaneous disc decompression, interbody fusion, artificial disc replacement, dynamic stabilization system, have the exact effects on the symptoms due to intervertebral disc degeneration.
ABSTRACT
This study aimed to review the improvement of artificial joint materials to search ideal materials for artificial joint. The developing process of metal artificial joint, high polymer artificial joint, ceramic-made artificial joint and compound material artificial joint was introduced and the material surface processing was explored. Selection of materials for artificial joint is determined by many factors. Each material has the specific benefits and drawbacks, so we can improve their performance by certain processing. Although there are many studies about materials for artificial joint, no ideal material is identified. To develop the materials for artificial joint with high mechanical strength, good biocompatibility, strong abradability and long-term service life is the focus in future bone tissue engineering.
