Objective To investigate the early and long-term effects of enhanced ischemia/reperfusion injury on the transplanted abdominal aorta. Methods Abdominal aorta grafts from Sprague-Dawley (SD) rats were cold stored for 1 or 24 hours, and they were orthotopically transplanted to SD or Wistar recipients. The pathohistological changes and the expression of TGF-? 1 in the grafts were observed. The levels of serum lipid peroxides before and after transplantation were also measured. Results The intima was significantly thicker in aorta transplants which was cold stored, both in SD→SD and SD→Wistar groups 10 weeks and 6 weeks after transplantation, whereas grafts which were cold stored for 24 hours showed pronounced thickening as early as 2 weeks after transplation. Serum lipid peroxides levels were elevated significantly 2 hours post-transplantation in all groups, but they were lowered 4 and 24 hours post-transplantation. The expression of TGF-? 1 in 24 hours of ischemia became stronger 1 week after transplantation regardless the difference in strains of the animal. Conclusions The enhanced ischemia/reperfusion injury can aggravate the infiltration of inflammatory cells, intensify the expression of TGF-? 1, accelerate the thickening of intimal layer.

Objective To investigate the cause, the clinical manifestation, the diagnosis and the treatment of subacute thyroiditis. Methods The medical history, clinical characteristics, laboratory data, nuclear medicine tests and treatment of 76 cases of subactue thyroiditis were analyzed. Results Subacute thyroiditis was more common in women than men, and 76 3% cases with subacute thyroiditis occurred during 30~49 years old. Almost all cases were characterized by enlargement of the thyroid with pain and tenderness, 49 cases of which showed that radioiodine uptake was low with increased serum thyroid hormone levels. 25 cases were treated with prednisone, 23 cases were treated with intrathyroid injection of dexamethasone, 23 cases were treated with intrathyroid injection of dexamethasone and triamcinolone, all recovered well, and 5 cases underwent operation incorrectly. Conclusions Confirmation of subacute thyroiditis should put emphasis on a complete medical history, physical examination and necessary tests. Nuclear medicine tests play an important role in diagnosis of subacute thyroiditis, and the diagnostic drug treatment or fine needle aspiration biopsy may be performed in suspected cases. Glucocorticoid is the best medicine for treating this kind of disease. There is no need for operation therapy of subacute thyroiditis.
