Objective To compare the clinical effects of extracorporeal shock wave treatment (ESWT) on lumbar ramus posterior nervorum spinalium syndrome and to compare the effectiveness of applying it in X-ray orientation with pain-point orientation.MethodsSixty patients with lumbar ramus posterior nervorum spinalium syndrome were randomly divided into an X-ray orientation group and a pain-point orientation group with 30 subjects in each group.The two groups then received ESWT with the X-ray orientation and pain-point orientation,respectively.The ESWT was delivered at the energy of 0.12 to 0.20 mJ/cm2 and the frequency of 60-80 pulses per minutes.A total of 1000-1500 shock wave pulses were delivered every time.Three sessions of ESWT were administered,with a 3-5 days of interval between each session.The results were rated using the 75 scores of the lumbar function quantification index recommended by Greenough.Ratings were done before treatment,and after the first,the second and the third treatment.ResultsThere was no significant difference between the groups' average index scores before treatment.There were however significant differences from the baseline scores after the first,the second and the third treatments.There was no significant difference in average lumbar function quantification scores between the groups after the first treatment,but the inter-group differences were statistically significant after the second and the third treatments.After three treatments the cure rate in the X-ray orientation group was 76.7％ and overall effectiveness was 93.3％.Both were significantly higher than in the pain-point orientation group (33.3％ and 76.7％ respectively).ConclusionsThe advantages of X-ray orientation when administering ESWT for lumbar rami posterior nervorum spinalium syndrome are more exact positioning and more effective treatment.The effect was obviously better than with pain-point orientation.

To generate recombinant adenovirus expression vector of human Sema4C gene and observe its expression in mouse myoblasts cell line C2C12 for ensuring easy access to investigate the role of Sema4C gene during myogenesis. The recombinant plasmid was packaged and amplified after being transfected in HEK293 cells through Lipofectamine. After infecting C2C12 myoblasts with recombinant adenovirus vector, the adenoviral infection efficiency was determined by confocal microscope which showed that the expression of green fluorescence could be detected at 12h and then reached peak at 24h after recombinant adenovirus infection. The infection efficiency was almost 100% confirmed by FACS examination. Detection of WB indicated that the expression of Sema4C in C2C12 of recombinant adenoviral infection group was significantly higher than that of the control group (P

OBJECTIVE: To estimate the application of prognosis evaluation of ulnar nerve injury by 1H-magnetic resonance spectroscopy (1H-MRS). METHODS: The metabolites of first dorsal interossei (FDI) of two hands from 12 healthy volunteers and 1 volunteer with complete ulnar nerve injury were detected by 1H-MRS and the data were statistically analyzed. RESULTS: For the FDI of healthy adults, the female peaks area of extra-myocellular lipids (EMCL) was higher than the male (P < 0.05); There was no significant difference in Cho, Cr and intra-myocellular lipids (IMCL) between male and female (P > 0.05); There was no significant difference in all the peaks area between the left and right hand (P > 0.05). The EMCL peak of the injury side was higher than that of the healthy side, and the area of FDI was reduced in the volunteer with ulnar nerve injury. CONCLUSION Noninvasive and quantitative detection of 1H-MRS may be valuable for prognosis evaluation of peripheral nerve injury.
