CXCR4/CXCL12 expression in the salivary gland and its significance in primary Sj?gren's syndrome / 中华风湿病学杂志

Objective To investigate the expression of CXCR4 and CXCL12 in the labial gland of patients with primary Sj?gren's syndrome (pSS), and to explore their role in the pathogenesis of pSS. Methods The expression of CXCR4 and CXCL12 in labial gland tissues was detected by immunohistochemistry in 32 cases of newly diagnosed pSS and 30 cases of oral mucosa cysts or trauma patients. The expression level, intensity and location were analyzed and compared statistically. χ2 test and Spearman correlation analysis were used for statistical analysis. Results The positive rate of CXCR4 in the test group was 91%(n=29), which was significantly higher than that in the control group (33%, n=10, χ2=21.77, P=0.001). The positive rate of CXCL12 in the test group was 97%(n=31), which was significantly higher than that in the control group 40%(n=12), and the difference was statistically significant ( χ2=23.57, P=0.001). Conclusion CXCR4 and CXCL12 are highly expressed in labial gland of pSS patients, this suggests that they participate in the pathological process of pSS local inflammatory response and play an important role in pSS pathogenesis.

Effect of 99Tc-methylene Diphosphate Combined with Rehabilitation on Ankylosing Spondylitis / 中国康复理论与实践

@#ObjectiveTo observe the effect of 99Tc-methylene diphosphate (99Tc-MDP, Yunke) combined with rehabilitation on ankylosing spondylitis (AS).Methods118 AS patients were randomly divided into the treatment group (n=58) and control group (n=60). The treatment group was treated with meloxicam, sulfasalazine and vein injecting Yunke combined rehabilitation. The control group was treated only with meloxicam and sulfasalazine. The changes of both clinical and experimental indexes of two groups before and after treatment were analyzed.ResultsAfter two therapeutic courses, a much better result was obtained in the treatment group compared with the control group at the respects of releasing arthralgia, shortening morning stiffness, improving range of spinal motion, and decreasing the levels of ESR, CRP, PLT and IgM, ect (P<0.05～0.01) without obvious side effects.ConclusionThe effect of Yunke combined with rehabilitation on AS is evident.
