Manipulative reduction for lumbar intervertebral disc herniation: a controlled clinical trial / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the effects of manipulative reduction on pain and clinical curative effect in patients with lumbar intervertebral disc herniation.</p><p><b>METHODS</b>Eleven thousands one hundred and twenty-eight patients with lumbar intervertebral disc herniation from our hospital were enrolled from November 1986 to June 2007. They were randomly divided into control group and treatment group. Patients of the control group received lumbar traction and various physiotherapies. Patients of the treatment group received manipulative reduction, besides the treatment in the control group. The treatment was performed once a day,ten times as a course. Curative effects were assessed three courses later. Pain was evaluated by visual analogue scale before and after the treatment.</p><p><b>RESULTS</b>No significant difference in the score of visual analogue scale was found before the treatment in the two groups (P > 0.05). As compared with the score before treatment,it was decreased by 4.73 points after treatment in the control group, and decreased by 6.37 points in the treatment group. The decrease was more significant in the treatment group than the control group (P < 0.01). The healing rate was 47.28% and total effective rate was 96.37% in the control group; The healing rate was 73.44% and total effective rate was 98.61% in the treatment group (P < 0.01).</p><p><b>CONCLUSION</b>Manipulative reduction for lumbar intervertebral disc herniation can remarkably relieve lumbar pain and improve clinical curative effect.</p>

Application of diffusion weighted echo-planar MR imaging in head and neck lesions / 中华放射学杂志

Objective to investigate the value of diffusion-weighted echo-planar MR imaging in the diagnosis of head and neck lesions.Methods Fifty-seven patients with 85 head and neck lesions were enrolled in the study,including 22 patients with 22 malignant tumors,13 patients with 13 benign tumors, 13 patients with 17 cystic and liquefactive lesions(including 8 patients with 12 cystic lesions,4 patients with 4 tumor necrosis,1 patients with 1 abcess)and 33 lymph nodes.The lesions were all confirmed by operation and clinical follow up.Echo-planar difffusion-weighted imaging (DWI)was performed with different b values (0,500,and 1,000s?mm~(-2)),and the apparent diffusion coefficients (ADCs)were measured.Results Malignant and benign tumors had different characteristics in DWI with different b values.With the increase of b value,the signal intensity of tumor/spinal cord ratio decreased quickly in DWI in benign tumors,while the signal intensity of tumor/spinal cord ratio remained similar in DWI in malignant tumors.The mean ADC value of'malignant tumors[(0.78?0.24)?10~(-3)mm~2? s~(-1)] was significantly lower than that of benign tumors [(1.48?+0.20)?10~(-3)mm~2?s~(-1)] (t = 8.9,P
