Objective To investigate the clinical-pathological feature of careinoma showing thymus-like dif- ferentiation(CASTLE) of the thyroid. Methods The clinical data, histopathologie changes and immunohistoche- mical findings were studied in 1 case of carcinoma showing thymus-like differentiation of the thyroid with review of the related literature. Results The age of the patient was 38 years old. The clinical manifestation displayed a pain- less mass in the thyroid. On ultrasound the tumor appeared hypoechoic. Histologically the tumor cells were arranged in nests and islands accompanied by desmoplasfie strorna. The architecture thus showed a superficial resemblance to the lobulation seen in thymic carcinomas. The tumor was characterized by squamoid or syheytial-appearing cells with lightly eosinophilic cytoplasm. Nuciec were oval, pale to versicular, and had small distinct nudeoli. Immunohistoche- mically the tumor cells were positive for CK, CD5, CD117 but neyative for TG, Calcitonin, SYN, NSE, TTF- 1, EBV. Conclusion CASTLE is a very rate a carcinoma thyroid with architectural resemblance to thymic epithelial tumors. The immunophenolype of CASTLE is identical with that of thymie carcinoma.

Objective To study the protective effect of rose (Rosae Rugosae Flos) essential oil on acute myocardial infarction in mice, and explore its mechanism. Methods The model of acute myocardial ischemia in mice was established by intraperitoneal injection of isopropyl adrenaline. The myocardial tissue pathological changes and the degree of myocardial injury in mice were observed by HE staining and TTC staining. Activities of super oxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in myocardial tissue of mice were determined, and activities of creatine kinase isoenzyme (CK-MB) and lactate dehydrogenase (LDH) in serum of mice were determined as well. Results HE staining results showed that rose essential oil group (160, 80, and 40 mg/kg) can significantly improve myocardial tissue pathological injury in mice; TTC staining results showed rose essential oil (160, 80, and 40 mg/kg) can significantly reduce the myocardial ischemia areas in mice. Compared with model group, SOD and GSH-Px in the myocardial tissue of mice significantly increased (P < 0.05, 0.01), while enzyme activity of serum LDH and CK-MB significantly reduced in rose essential oil group (P < 0.05, 0.01). Conclusion Rose essential oil has certain protective effect on acute myocardial infarction injury and its mechanism may be associated with inhibiting oxidative damage, enhancing activities of anti-oxidant enzymes, and reducing the lipid peroxidation damage.

Objective This study is undertaken to evaluate the changes of serum cytokine levels in different stages of collagen induced arthritis(CIA)rats,to search for the specific proteins related with rheuma- toid arthritis(RA)pathogenesis and inflammation,and to explore the mechanism of RA pathogenesis.Methods Rat cytokine antibody array coated with 19 specific cytokine antibodies was used to examine serum samples at peak and late stage of CIA rats,and were compared to normal cytokine levels.At the same time,ELISA assay for serum TNF-?production was used to verify the array results.Results Among the target cytokines,10 up- regulating cytokines were kept in high expression in different phases of disease,while 1 showed significant change only at the peak of disease.There was no downregnlating cytokines in the results.Serum TNF-?assay results were consistent to the array results.Conclusion Cytokines show different expression in CIA at differ- ent stages,and specific cytokines can be used as the candidates to further study of the RA pathogenesis.This study also provides molecular makers for early diagnosis.

Corresponding author: SONG Guang yao Human umbilical venous endothelial cells (HUVEC) were incubated with free fatty acids (FFAs) of various degrees of saturation. C18:1 and C18:2 inhibited the synthesis of nitric oxide (NO) and endothelin (ET) in HUVEC, and ET synthesis was inhibited much more than NO synthesis, and C18:0 increased ET synthesis in HUVEC, suggesting that the effects of FFAs on HUVEC were related to their degree of saturation.

Objective To explore the risk factors of surgical treatment for children’ s tethered cord syndrome. Methods Retrospective-ly analyzed the clinical data of 43 tethered cord syndrome children who had undergone surgical treatment from January 2007 to December 2009,and to evaluate the efficacy of the surgical treatment. Meanwhile,The Cox proportional hazards regression model was adopted to evaluate the surgical efficacy. Results 28 children received effctive curative effect after the surgical treatment in 43children with tethered cord syn-drome,the total effective rate was 65. 12%. Cox medol showed that tight filum terminale(P<0. 05), operation methods (P<0. 05)and the duration of the disease(P<0. 05)were independent risk factors of surgical treatment for children’s tethered cord syndrome. Conclusion The operativeefficacy of children’ s tethered cord syndrome were influence by the tight filum terminale,operation methods and the duration of the disease.

Objective To explore the reproductive toxicity of 2,4-D butylate to the testis in male mice.Methods Forty-eight ICR male mice were randomly divided into four groups : the control group, and three 2,4-D butylate experimental groups (10, 20, 40 mg/kg), 12 mice in each group.2,4-D butylate was intragastrically administered once a day and six days per week for five weeks .At the end of the exposure, the activities of total antioxidant capacity (T-AOC), Na+ K+-ATPase, Ca+ + Mg+ +-ATPase, lactate dehydrogenase (LDH) and succinate dehydrogenase (SDH) in testis homogenate were measured by spectrophotometry .Results The activity of T-AOC was gradually decreased with the increase of doses, with a significant difference between the high dose group and other groups .The activities of LDH in the moderate and high dose groups were significantly lower than those of the low dose group and control group , and there was a significant difference between the high dose group and moderate dose group .The activities of SDH in the testis was gradually decreased with the increase of the 2,4-D butylate dose, showing significant differences between the high dose group and the moderate dose and control groups , and between the high and moderate dose groups and the low dose group . The activities of Na +K +-ATPase in the moderate and high dose groups were significantly lower than that of the control and low dose group.The activities of Ca++Mg++-ATPase was significantly lower in the experimental groups than that in the control group.Conclusion Exposure to 2,4-D butylate has certain toxic effect on the testicular tissue in male mice .
