RESUMEN
OBJECTIVE: To investigate the growth of craniopharyngioma involving the third ventricular floor with regard to the hypothalamus by detecting expressions of leukocyte common antigen (CD45) and intercellular adhesion molecule (ICAM-1) in the tumor tissue. METHODS: The expressions of CD45 and ICAM-1 proteins in 30 craniopharyngioma samples with third ventricular floor involvement were detected by SP immunohistochemistry. RESULTS: The inflammations labeled by CD45 were identified commonly in the craniopharyngioma tissues involving the third ventricular floor. The expression of ICAM-1 was mainly in the inner tumor cells and interstitial cells, but not detected in the basilar tumor cells growing toward the third ventricular floor. Adamantinomatous craniopharyngiomas showed markedly higher CD45 and ICAM-1 expressions than squamous papillary tumors (P<0.05). CONCLUSION: Inflammatory adhesion largely characterizes the growth of the craniopharyngioma tissues involving the third ventricular floor toward the hypothalamus without the tendency of invasion. The difference in the inflammation between the two types of craniopharyngioma may affect the prognosis of the patients.

OBJECTIVE: To investigate the effect of Jingui Shenqi Pill (JSP) on the expression of glucocorticoid receptor (GR) in the skin lesion and its clinical effect in treating bullous pemphigoid (BP) patients. METHODS: Thirty BP patients were randomly divided into the treatment group (n=15) treated with JSP plus prednisone and the prednisone group (n=15) with prednisone alone both for 4 weeks. And a normal control group was set up also. Expressions of GR-alpha and GR-beta in the skin lesion of BP patients and the normal skin of the normal control were detected by immunohistochemical assay. Results The total effective rate was 93.33% in the treatment group, significantly higher than that in the prednisone group which was 73.33% (P < 0.05); GR-alpha expression was higher in the treatment group than that in other two groups (P < 0.01), while GR-beta expression in the treatment group was lower than that in the prednisone group (P < 0.01). CONCLUSION: JSP could increase GR-alpha expression and decrease GR-beta expression in the skin lesion of BP patients, so as to improve sensitivity of skin to glucocorticoid.
