RESUMO
Gallstone disease is a common and frequently seen disease of digestive system, and is a common cause of inflammation of gallbladder and bile duct, biliary tract tumor and obstructive jaundice, however, its pathogenesis is not yet fully understood. Recent studies have revealed that intestinal flora and immunity play important roles in the formation of gallstones. This paper reviewed the relationship between the abundance and composition of intestinal flora, immuno - globulins, mucins and immune cells, as well as the interactions between intestinal flora and biliary immunity and gallstone formation for providing new ideas and methods for gallstone prevention and treatment.
RESUMO
Objective To investigate the effects of iodine on the pathogenesis of Graves′ disease (GD). Methods The thyroid epithelium cells (TEC) from GD patients and para adenoma normal tissue from thyroid adenoma patients wereculturedrespectivelywithdifferentNaⅠconcentrations from 0 to 1 mg/L. The HLA DR expression of TEC was detected with Western blot. Meanwhile, the morphological change of TEC was observed after treatment of NaⅠ by scanning electronmicroscope (SEM). Results (1) When the concentration of NaⅠ in culture medium was over 100 ?g/L, the amount of HLA DR expression of TEC increased in GD group (P
