Objective To study the pathological morphology of thyroid specimen after thyroid arteries embolization. In order to select appropriate size of embolizing granules, the diameters of thyroid arteries in Graves' disease were measured. Methods Multiple slides of embolized thyroid tissues from superior pole, body and inferior pole of the resected thyroid glands were made. After being embedded and stained, pathological morphology was observed and diameters of arteries in various parts of thyroid glands were measured under microscopy. Results Pathological examination of thyroid glands showed that superior and inferior thyroid arteries and most of their branches were embolized with ischemic necrosis and fibrosis in the embolized thyroid tissue. Follicular epithelium appeared as flat or cubic shapes with colloid reduction. Average diameter of main branches of superior artery was 440～550?m and that of inferior artery was 300～375?m. The diameters of capillary network in the thyroid body was 120～250?m, and the non embolized ones was 40～110?m. The diameter of isthmus was 130～150?m. Conclusions Pathological morphology of Graves' disease after thyroid arteries embolization showed that the excretion of thyroid glands would be decreased and equivalents to subtotal thyroidectomy.

All patients came into persistent comatose state immediately. 75% patients had abnormal CT scan findings. MRI showed more sensitive. It could reveal injury appearance of corpus callosum and brain stem clearly. Hypothermic therapy and calcium ion antagonist were used. Conclusions combination of clinical manifestations and special imaging features helped to diagnosis of DAI in early stage. Intensive care and preventing secondary brain injury were the important treatment points.

Objective To explore the effect of hyperbaric oxygenation (HBO) on generation of free radicals and the permeability of blood-brain barrier(BBB) during cerebral ischemia-reperfusion(CIR). Methods Three hundred and twenty Kunming mice were randomly divided into four groups: a sham operation group, a HBO group, a CIR group, and a HBO + CIR group, with 80 mice in each group. Conscious mice were used to establish the CIR model, and 0.25MPa (ATA) HBO were applied 5 times after operations. The activities of SOD, CAT, GSH-PX and the concentration of MDA, EB in the cerebral hippocampal tissues in each group were measured with colorimetry. The cerebral hippocampal tissues were harvested and processed, then observed and compared with transmission electron microscopic observation. Results Compared with the sham operation group, the activities of antioxidation enzymes (GSH-PX,SOD, CAT) in CIR group decreased significantly (P

Objective To observe the effects of blood nourishing and wind expel formulae on learning and memory capabilities of rats with tic disorders. Methods Intradialytic Parenteral Nutrition peritoneal injection was used to establish the rat model of tic disorders. The successful test subjects were categorized into 5 different groups, namely the model group, the Chinese medicine groups (low dosage, medium dosage and high dosage) and the western medicine group. The test groups were each given gastric perfusion of the related medicine, whereas the control and model groups were each given equal amounts of saline solution continuously for 8 weeks. Open field test and water maze test were carried out in the 1st, 4th and 8th weeks to evalute the learning and memory capabilities. Results In comparison with the control group, the model group showed obvious increase in movement across grid and decrease in vertical locomotion. Statistical significance was obtained showing an increase in vertical locomotion in the treatment groups compared with the model group. In the Chinese medicine groups, the medium and high dosage groups exhibited shorter escape latency and increased exploratory behavior (P<0.05) in the 4th and 8th weeks. Conclusion Among the blood nourishing and wind expel formula, the medium and high dosage showed ameliorating effects on the memory and learning capabilities of rats with tic disorders.

Objective To compare the clinical efficacies between warm needling and Ibuprofen sustained release capsules (a nonsteroidal anti-inflammatory drug, NSAID) in treating patients with dysmenorrhea in adenomyosis. MethodSixty-five patients with dysmenorrhea induced by adenomyosis were randomized into a treatment group of 33 cases and a control group of 32 cases. The control group was intervened by oral administration of Ibuprofen sustained release capsules, while the treatment group was intervened by warm needling.The intervention lasted 3 menstrual cycles and a 3-month follow-up was studied. The Visual Analogue Scale (VAS), dysmenorrhea symptoms scores and clinical efficacy were compared between the two groups.ResultThe VAS scores after the intervention and inthe first and second months of the follow-up study were significantly different from the pre-treatment score in the two groups (P<0.01); the VAS score of the 3-month follow-up was significantly different from the score before the intervention in the treatment group (P<0.01). There were significant differences in comparing the VAS score after the intervention and in the follow-up study between the two groups (P<0.01), and the treatment group was superior to the control group. The dysmenorrhea symptoms scoresdeclined significantly after the intervention and in the first and second months of the follow-up study in both groups (P<0.01); the dysmenorrhea symptoms score of the 3-month follow-up study decreased in the treatment group and was significantly different from the pre-treatment score (P<0.01). There were significant differences in comparing the dysmenorrhea symptoms scores in the second and third months of the follow-up study between the two groups (P<0.01). The total effective rate was 93.9% in the treatment group, significantly better than 62.5% in the control group (P<0.01).ConclusionWarm needling is effective in easing pain and improving the symptoms of dysmenorrhea in adenomyosis, and can produce a consistent efficacy after the termination of thetreatment; it's superior to NSAIDs in comparing both short-term and long-term treatment efficacies.
