Objective To observe the therapeutic effects of stellate ganglion block (SGB) with oxycodone and acetaminophen tablets on the treatment of migraine. Methods 100 patients with migraine were divided into two groups randomly. They received SGB with oxycodone and acetaminophen tablets (experimental group) or only SGB (control group) respectively. The parameters included pain intensity before and 1 d,3 d,1 w,1 m and 3 m after the treatment, and pain relief rate of each patient. The adverse effects were also evaluated. Results The pain intensity described as numeric rating score (NRS) decreased in the two groups at each time point. In the experimental group, the value of NRS was significantly less than that in the control group at 3d,1m and 3m after the treatment. The effec-tive rate ha the experimental group and the control group were 88% and 68%. Conclusion SGB with oxycodone and acetaminophen tablets is more effective for migraine and deserves widely used in patients.

OBJECTIVETo study the expression of EpCAM and E-cadherin in papillary thyroid carcinoma and to analyze its correlation with various clinicopathologic parameters.
METHODSImmunohistochemical study for EpCAM and E-cadherin was carried out in 91 cases of papillary thyroid carcinoma. Twenty-four cases of papillary hyperplasia of thyroid were used as controls.
RESULTSIn all of the 24 cases of papillary hyperplasia, EpCAM was located on the cell membrane, while in the 91 cases of papillary thyroid carcinoma studied, EpCAM was located within the cytoplasm, with 36.3% (33/91) showing nuclear localization as well. In all the papillary hyperplasia cases studied, E-cadherin showed membranous expression. E-cadherin expression was reduced in 84.6% (77/91) of papillary thyroid carcinoma, as compared with the surrounding native thyroid parenchyma. Amongst the 33 cases of papillary thyroid carcinoma which showed nuclear localization of EpCAM, 30 cases also showed reduced E-cadherin expression. There was a positive correlation between nuclear expression of EpCAM and loss of E-cadherin expression (P = 0.000; Spearman correlation coefficient = 0.857). Nuclear expression of EpCAM correlated with follicular variant of papillary thyroid carcinoma and presence of extrathyroidal extension ( P = 0.037 and 0.033, respectively). Loss of E-cadherin expression correlated with age of patients and presence of lymph node metastasis (P = 0.018 and 0.010, respectively).
CONCLUSIONSE-cadherin expression is reduced in papillary thyroid carcinoma, as compared with native thyroid parenchyma and papillary hyperplasia. Papillary thyroid carcinoma shows loss of EpCAM membranous expression and increased cytoplasmic/nuclear accumulation. Detection of these two markers may provide a valuable reference in defining the biologic behaviors of papillary thyroid carcinoma, including extrathyroidal extension and lymph node metastasis.

BACKGROUND:The low oxygen environment after femoral fracture and cerebral trauma wil induce series of related cytokines expression, including hypoxia-inducible factor 1αand core binding factorα1, which play key roles in regulating bone healing. However, whether the accelerated bone healing is correlated with the expression of hypoxia-inducible factor 1αand core binding factorα1 is stil unknown.
OBJECTIVE:To construct rat models of brain injury, to compare the expression level of hypoxia-inducible factor 1αand core binding factorα1 in femoral fracture combined with cerebral trauma rats and simple femoral fracture rats, and to assess the influence of cerebral trauma on bone healing.
METHODS:Rats were randomly divided into blank group, simple femoral fracture group and femoral fracture combined with cerebral trauma group. At 1, 2, 3 and 5 weeks after modeling, rats were executed. Bone healing was evaluated using femoral fracture end X-ray score and hematoxylin and eosin staining at cal us tissues. Besides, the expression levels of hypoxia-inducible factor 1αand core binding factorα1 of three groups were determined with immunohistochemistry.
RESULTS AND CONCLUSION:Bone healing in the femoral fracture combined with cerebral trauma group was better than that of simple femoral fracture group. There was significant difference in the expression level of hypoxia-inducible factor 1αand core binding factorα1 between the simple femoral fracture group and femoral fracture combined with cerebral trauma group (P<0.05). At the same time, the level of simple femoral fracture group and femoral fracture combined with cerebral trauma group was significantly higher than that of blank group, and that in femoral fracture combined with cerebral trauma group was significantly higher than that of simple femoral fracture group (P<0.05). Results verified that the expression levels of hypoxia-inducible factor 1αand core binding factorα1 of rats with femoral fracture combined with cerebral trauma were significantly high, which may be the major reason why the bone healing was accelerated after fracture combined with brain injury.
