RESUMO
Objective To observe the clinical efficacy of Qihuang needle therapy in treating knee osteoarthritis.Methods Sixty knee osteoarthritis patients were randomly divided into treatment group and control group,30 cases in each group.The treatment group was given Qihuang needle therapy and the control group was given conventional acupuncture therapy.After treatment for 10 days,we evaluated the curative effect of the two groups by the scores of the simplified McGill pain scale (MPQ) and the Lysholm knee scoring criteria.Results (1) After treatment for 10 days,the symptoms of pain,swelling,stiffness,and inhibited bending and stretching of knee joints of the two groups were relieved.Pain rating index (PRI),visual analogue scale (VAS) scores and present pain intensity (PPI)of MPQ in the two groups were obviously decreased,while Lysholm knee scores were markedly increased(P ＜ 0.01 compared with those before treatment),and the effect of the treatment group was superior to that of the control group (P ＜ 0.05).(2) The total effective rate of the treatment group was 86.67％,and that of the control group was 66.67％,the difference between the two groups being significant (P ＜ 0.05).Conclusion Qihuang needle therapy is effective for the treatment of knee osteoarthritis,with the advantages of shorter treatment course,better therapeutic effect and being more practical.
RESUMO
Objective To investigate the value in distinguishing benign and malignant vertebral fractures with MR diffusion-weighted imaging(DWI).Methods 31 patients with 58 vertebral fractures were underwent routine MRI scanning and echo-planar DWI(EPI/DWI).The materials were divided into benign group(n=32,20 cases),malignant group(n=18,8cases),tuberculosis group(n=8,3cases) and normal vertebral body group(n=31). Signal intensities on DWI were compared and apparent diffusion coeffient(ADC) values of normal and abnormal vertebral bodies were calculated. ADC values among the benign,malignant,tuberculosis vertebral bodies and normal ones were quantitatively analyzed and compared.Results The ADC values of benign,malingnant,tuberculosis and normal vertebral bodies were (1.44?0.41)?10 -3 mm2/s,(0.94?0.17)?10 -3 mm2/s,(0.98?0.13)?10 -3 mm2/s and(0.42?0.16)?10 -3 mm2/s ,respectively. The ADC values of the three abnormal groups were higher than normal group ( all P0.05). The sensitivity and specificity of ADC for the diagnosis of malignant lesion were 72.2% and 90.6% if the upper bound of 95% confidence interval was set as a differential level.Conclusion DWI provides an important supplement to the routine MRI in the differentiation of benign with malignant vertebral fractures.
