Methods: 66 cases of acute lumbar vertebral articular dyskinesia were randomly divided into acupuncture plus manual reposition group (treatment group, n=33) and routine manual reposition group (control group, n=33). Yaotong point was punctured, when, the patient was asked to move his or her waist simultaneously. Results: After one session of treatment, of the two 33 cases in treatment and control groups, 28 (84.85%) and 20 (60.61%) were cured, 4 (12.12%) and 9 (27.27%) were improved, and 1 (3.03%) and 4 (12.12%) failed in the treatment. The therapeutic effect of treatment group was significantly superior to that of control group (P<0.05). Conclusion: Acupuncture combined with manual reposition is apparently superior to simple routine manual reposition in relieving acute lumbar vertebral articular dyskinesia.展开更多

Here, this impact is evaluated in TMJ articular disc and articular cartilage using an in vivo model of unilateral occlusal plane impact and by analysis of serial tissue sections stained with Hematoxylin-Eosin (H-E) or with Masson trichrome technique. Thus, six groups of 5 Wistar rats (200 - 250 g) are subjected to biomechanical dental stimulation by placing unilateral resin occlusal interference, or unilateral tooth wear made by upper left molars artificial mechanical devastation (1 control and 2 experimental groups for each treatment). Each treatment is evaluated two times at 1 and 15 days post-treatment. By H-E staining, control groups show chondrocytes arrangement as several cord cell groups in comparison with the experimental groups, which show an arrangement in one cord cell along of articular disc. However, this yields no significant difference (p < 0.05) in cell number between control and experimental groups. In contrast, in articular cartilage chondrocytes are random distributed along the superficial zone in control groups, while in experimental groups cell-free regions are observed in superficial zone. An image Blue hue analysis for trichrome stain is performed to quantify collagen;this shows a significant collagen decrease (p < 0.05) in almost all experimental groups compared with the controls. A degenerative process biomechanically induced by unilateral occlusal plane modification, causes cell and tissue changes on the TMJ structures that remain the degenerative changes observed in early osteoarthritis.展开更多
