The influence of anisodamine on the cerebral blood flow in the uncompletely ischemic brains was studied with radioactive biomicrosphere assay. After the bilateral carotid arteries were occluded the cerebral blood flow drawmatically decreased and middle part of the hemisphere had the most severe reduction. Anisodamine 10mg ? kg-1 iv selectively increased the cerebral blood flow in this area and 20mg ? kg-1 increased that in the whole hemisphere. When it was used in the dose of 40mg ? kg-, the increasing effect on the cerebral blood flow became weaker. While the cerebral blood flow decreased, the myocardial blood flow increased significantly after bilateral carotid artery occlusion. Anisodamine 20mg ? kg-1 iv made it further increase and 40mg ? kg-1 iv made it decrease. The cardiac index was not influenced by bilateral carotid artery occlusion and anisodamine 10~20mg ? kg-1 iv, but was significanntly increased by anisodamine 40mg ? kg-1 iv. These results suggested that anisodamine may be used in the treatment of ischemic cerebral diseases and should be used in different doses according to different purposes.

OBJECTIVETo observe the effects of electroacupuncture (EA) at "Dazhui" (GV 14) on Wnt-β-catenin signal pathway in annulus fibrosus cells in intervertebral disc in rats with cervical spondylosis.

METHODSForty SD rats were randomized into a control group, a model group, an EA group and a medication group, 10 rats in each one. Rats in the control group were treated with sham operation, only incision on local skin; rats in the remaining groups were made into cervical spondylosis models. After model establishment, rats in the control group and model group received fixed treatment under identical condition; rats in the EA group were treated with EA at "Dazhui" (GV 14), 30 min per treatment; rats in the medication group were treated with intragastric administration of meloxicam tablets. Treatments were both given once a day, and 14 days were taken as one session; there was an interval of 2 days between two sessions, and totally two sessions were given. After the treatments, immunohistochemistry was applied to measure the expression of Wnt, glycogen synthase kinase-3β (GSK-3β) and Axin in annulus fibrosus cells; western blot was used to test the expression of P-β-catenin.

RESULTSIn the control group, there were more positive cells of Wnt, GSK-3β and Axin, which were intensively distributed, deeply colored, and strongly positive; In the model group, there were less positive cells of Wnt, GSK-3β and Axin, which were sparsely distributed and weakly positive. The expression of Wnt, GSK-3β, Axin and P-β-catenin in the model group was less than that in the control group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin in the EA group and medication group was higher than that in the model group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin was not significantly different between EA group and medication group (all P > 0.05).

CONCLUSIONEA could delay the degeneration of intervertebral disc, which may be related to EA inhibiting signal pathway of Wnt-β-catenin.

Background and purpose: Primary intracranial epithelioid haemangioendothelioma (EH) was rare. This study was to discuss the clinical pathological features, radiographic findings, treatment and prognosis of primary intracranial EH combined with literature review. Methods: We reviewed a case of EH reported from our hospital, and comprehensively analyzed the related literature. Results: Based on our report and review of the literature, EH is rare and with borderline or uncertain behavior. The original tumors demonstrated specific image features. The tumor usually appeared as a small nest or cords composed of eosinophilic epithlioid or spindled cells.Immunohistochemical assay were positive for endothelial markers CD31, CD34 and FⅧ. EH may be treated with complete surgical resection whenever possible and is sensitive to radiation. The EH has a favorable prognosis. Conclusion: EH has variable malignant potential, and should be differentiated from meningioma. Total resection and close follow-up is recommended. Additional radiotherapy is advised for residual tumors.

Objective:To assess the ability of axillary reverse mapping (ARM) to identify and preserve the arm lymphatics drainage as well as determine its ability to reduce lymphedema. Methods:A total of 300 breast cancer patients who underwent axillary lymph node dissection (ALND) from June 2009 to May 2011 were enrolled in this study. Methylene blue dye (2 mL to 3 mL) was injected into the ipsilateral upper inner arm along the medial intramuscular groove to map the upper extremity lymphatic drainage system prior to ALND. The blue lymphatic and lymph nodes were identified and preserved during the operation. The change in the arm circumference was the selected method of measurement. The difference in the bilateral upper arm circumference was recorded after 2 months (difference≥2 cm is defined as lymphedema). Results:The ARM was performed successfully in 195 (65%) of 300 patients. The incidence of lymphedema was significantly lower in the successfully mapped patients than in the failing mapping patients, with statistically significant difference during follow-up at 6, 12, 18, and 24 months post operation. Conclusion:The ARM technique can identify and preserve the arm lymphatics drainage and prevent upper extremity lymphedema after breast cancer axillary lymphadenectomy.
