Methods:Sixty cases of pathologically confirmed extra-axil tumors and tumor-like lesions involving bothmiddle and posterior cranial fossae were analyzed. They were divided into central and lateral types,the latter of which were subdivided into three types: middle cranial fossae type, posterior cranialfossae type and the over-riding type. The constitution and imaging features of each type wereanalyzed. Results: There were 12 cases of central type, including chordoma (n=5), pituitary adenoma(n=3), nasopharyngeal carcinoma (n=2), craniopharyn-gioma (n=1) and meningioma (n=l). 48 cases oflateral type including trigeminal nerve tumors (n=14), meningioma (n=12), epidermoid cyst (n=11),dural cavernous hemangioma (n=4), dermoid cyst (n=2), metastasis (n=2), hemangiopericytoma (n=1),paraganglioma of glonius jugular (n=1) and nasopharyngeal carcinoma (n=1). Each type of the lesionshad its own shape features, some of which were characteristic for some specific tumors. Most of thetumors and tumor-like lesions could be qualitatively diagnosed according to their imagingcharacteristics and the extent of the lesions could be defined definitely. Conclusion: It is helpfulto categorize extra-axial tumors and tumor-like lesions involving both middle and posterior cranialfossae according to their location for qualitative diagnosis and description of the extent of theselesions. It is of great clinical value in providing more precise and thorough imaging informationfor planning therapeutic methods and route of operation.展开更多

Methods： Eighty patients with thalamic pain syndrome were randomly allocated into two groups, with 40 cases in the treatment group receiving combined scalp and body acupuncture treatment and 40 cases in the control group receiving single body acupuncture treatment. The intervention was given for 28 d in total, and the effects were evaluated after 14-day and 28-day treatments. Results： The inner-group comparison of McGill Pain Questionnaire （MPQ） showed significant differences after the treatment d 14 in both of the two groups （P〈0.05）, and after the treatment d 28, the differences were even more significant （P〈0.01）. After 28-day treatment, compared with pre-treatment, the Transcranial Doppler （TCD） test detected significant changes in the two groups （P〈0.05）. The total effective rate was 72.5% in the treatment group versus 47.5% in the control group, and the difference was statistically significant （P〈0.05）. The 3-month follow-up study found the relapse rate was 0 in the treatment group and 15.8% in the control group, and the difference was significant （P〈0.05）. Conclusion： Acupuncture is effective in treating thalamic pain syndrome and combined scalp and body acupuncture can achieve even better results.展开更多
