Objective To investigate the clinical efficacy of stiletto needle acupuncture plus conventional acupuncture in treating cervical vertigo. Method Sixty patients with cervical vertigo were randomly allocated to treatment and control groups. The treatment group of 30 patients received stiletto needle acupuncture plus conventional acupuncture and the control group, conventional acupuncture alone. An assessment was made using the modified Cervical Vertigo Symptom and Function Evaluation Scale in both groups before and after treatment. Result After two courses of treatment, the total efficacy rate was 93.3% in the treatment group and 73.3% in the control group; there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the symptom score in the two groups and post-treatment difference in the symptom score between the two groups (P<0.01). Conclusion Stiletto needle acupuncture plus conventional acupuncture has a definite therapeutic effect on cervical vertigo. Its therapeutic effect is superior to that of conventional acupuncture alone.

Objective To investigate the effects,difficult points and technical key points of the interventional embolization in brain micro-aneurysms.Methods Retrospectively analyzed the material of the interventional embolization in 38 patients with brain micro-aneurysm.Results Twenty-six cases were treated with simple spring coil embolization technology,4 cases were treated with double micro-catheter embolization technic,2 cases were treated with embolization combining ballon assistive technic and 6 cases were treated with embolization combining stent assistive technic.All the 38 patients successfully embolized.The postoperative immediate cerebral angiogram to determine the degree of embolization:12 cases were 0 level,21 cases were 1 level and 5 cases were 2 level.The Rankin grade results showed that 0-1 score in 24 cases,2 scores in 10 cases,3-4 scores in 2 cases and 5 scores in 2 cases.Thirty-three patients were followed up for 6-12 months.No aneurysms recurred or re-raptured.Conclusions The spring coil embolization of brain micro-aneurysms is a feasible,safe and effective method,though the technics involved is difficulty.Selecting suitable embolization technics according to the characteristic of each micro-aneurysm can reduce the risk of operation,decrease complications and increase the successful rate.

Objective To investigate the imaging findings of primary bone malignant fibrous histiocytoma (PBMFH) in long bone. Methods MRI and XV ray examinations were performed in 10 patients with PBMFH in long bone confirmed by histology. CT scans were performed in 6 cases. Results Nine cases had single and 1 case had multiple lesions of single bone. Seven cases showed osteolytic bone destruction, and 3 cases showed mixed bone destruction. Only 1 case showed periosteal reaction. Gross bony ridge was seen in 3 cases on CT scan. All the patients demonstrated isointensity or hypointensity on T1WI, and slight hyperintensity signal on T2WI. Necrosis was seen in the lesion of 10 cases. Four cases showed obvious but heterogeneous enhancement after contrast medium injection. Eight cases had soft tissue mass beyond the scope of bone destruction. Conclusions Some imaging features may suggest the diagnosis of PBMFH in long bone.
