Changes of Expression in GDNF and GDNFR-?1 of Long-term Denervation of Posterior Cricoarytenoid Muscles / 听力学及言语疾病杂志

Objective To investigate the changes of the expression of GDNF and GDNFR?1 of long-term denervation of posterior cricoarytenoid muscles(PCAMs).Methods 38 patients with vocal paralysis were grouped into four according to their denervated period of time while 12 normal PCAMs as control group.Using double immunofluorescence stain,changes of GDNF and GDNFR1 expression were observed in myofibers at different time points after denervation.Results Double immunofluorescence stain with antibodies against GDNF and GDNFR1 showed no staining in the control group,and study groups.However,after the muscle denervation lasted for 6-12 months and 1-2 years,noted was a significant accumulation of GDNF and GDNFR1 protein in cytolemma and endochylema of myofiber.The mean grey scales and positive region ratios were compared using the image analysis system.The results revealed the levels of GDNF and GDNFR1 protein expression in 6-12 months group,1-2yr group changed significantly(P0.05).Conclusion The changes in expression of GDNF and the acceptor GDNFR-?1,a powerful neurotrophic factor,implied that a good nervous regenerated microenvironment in PCAMs within 2 years.This experiment indicated that denervated posterior cricoarytenoid muscles are able to regain their functions through reinneration within 2 years.

Clinical Observation on 85 Patients with Ankylosing Spondylitis at Active Stage Treated by Shudu Bushen Recipe Together with Western Medicine / 中医杂志

Objective To observe the clinical therapeutic effect of Shudu Bushen Recipe (Recipe to strengthen the spine and reinforce the kidney) on ankylosing spondylitis at active stage.Methods Totally 165 patients with ankylosing spondylitis at active stage were randomly divided into a treatment group (85 cases) and a control group (80 cases).Both groups were treated with Sulfasalazine and Aceclofenac,and the trentment group was given Shudu Bushen Recipe additionally.Six-month treatment was one course.The clinical changes such as morning stiffness,joint pain and function,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),immunoglobulin (Ig),X-ray of sacroiliac joint,and adverse reaction were observed.Results In the treatment group,the total effective rate was 94.12%,superior to that in the control group (76.25%),with a significant difference (P0.05).The adverse reaction occurred in the treatment group was less than that of the control group (P
