Objective To study the clinical characteristics and treatment of ACTH-secreting pituitary adenoma.

Relationship between the expression of uPA、PAI-1、bFGF、 microvessel density and the invasiveness of human pituitary adenoma;

Anatomical observation of operative approach of pituitary adenoma;

Metrological analysis of literature on pituitary adenomas reported during period 1994-2005 in China;

The expresion and significance of peroxisome proliferator-activated receptor-γ (PPAR-γ) in pituitary adenomas;

Relationship between p53,bFGF and MVD expression with invasiveness of pituitary adenomas;

Ocular presentations of pituitary adenomas and correlation with MRI features in 200 eyes;

The expression of PTEN protein in pituitary tumor and its significance;

Expression of estrogen receptor in human plurihormonal pituitary tumor;

Objective To examine the expression of estrogen receptor(ER) in different hormone-producing pituitary tumors in order to study the relationship between the specific hormone-secreting adenoma cells and the ER-immunoreactive tumorous pituitary cells.

MRI diagnosis value of dynamic contrast enhancement and FFE sequence to pituitary microadenomas;

Resection of pituitary microadenoma by transnasal transsphenoidal approach(report of 68 cases);

Conclusion Pituitary microadenoma treated by micro-operation through all removed add extent-removed can improve the effectiveness ratio.
