The features of the symptoms, laboratory tests and pathological characteristics of adrenal cortical and medullary hyperplasia were studied. In 6 cases of hypercatecholaminenia, plasma norepinephrine (NE), epinephrine (E), catecholamine (CA) and 24-h urinary vanillylmandelic acid (VMA), 17-hydroxycorticosteroid (OHCS) and 17-ketosteroid (KS) were determined. Adrenal glands were examined by CT scan and 131I-MIBG imaging. Pathological examination was performed after operation. The results showed that in 6 cases of hypercatecholaminenia (3 men and 3 women) aged from 34-50 years, the clinical features were just like "pheochromocytoma", for example, episodic headache, perspiration, palpitation, pallor, apprehension, nausea, tremor, anxiety and so on. Plasma levels of CA, NE and E were elevated in all 6 cases. 24-h urinary samples obtained at the onset revealed elevated VMA in 1 case. 24-h urinary cortisol was obviously elevated in all 6 cases. 24-h urinary 17-OHCS, 17-KS was normal. B-type ultrasound, CT, MRI and 131I-MIBG revealed 9 lateral adrenal gland diffuse or nodular enlargement in 6 cases. Pathologic examination showed adrenal cortical and medullary hyperplasia. Clinically, adrenal cortical and medullary hyperplasia resembled "pheochromocytoma". The most significant feature of this disease was both elevated plasma CA and 24-h urinary cortisol obviously. Pathologic examination showed adrenal cortex nodular hyperplasia and medullar diffuse or limit hyperplasia. Whether it is an independent disease or symptoms of the other disease has not final conclusion up till now.

OBJECTIVETo study the effect of osthole (Ost) on adrenocortical function in Y1 mouse adrenocortical tumor cells.
METHODSY1 mouse adrenocortical tumor cells were taken as subjects in this experiment. In 10.0%, 1.0%, and 0.1% serum DMEM-F12 medium, Y1 cells were treated with 1, 10, 25, 50, 100, and 200 micromol/L Ost for 24 and 48 h. 0.1% Dimethyl Sulfoxide (DMSO) was taken as negative control group and 1 mmol/L (Bu) 2cAMP as positive control group. Cell growth morphology was observed under inverted microscope. Contents of corticosterone were tested by ELISA. Expression levels of steroids synthase such as Star, Cyp11a1, Cyp21a1, Hsd3b2, Cyp11b1, Cyp11b2, Cyp17a1, and Hsd17b3 mRNA were detected by Real time quantitative PCR (RT-qPCR).
RESULTSY1 cell proliferation was obviously inhibited by 100 and 200 micromol/L Ost, and its inhibitory effect was more significant in 0.1% serum medium. Compared with the negative control group, gene expressions of Star, Cyp11a1 , Cyp21a1, Hsd3b2, Cyp11b1, Cyp17a1, and Hsd17b3 were significantly enhanced in the posi- tive control group (P < 0.05). Y1 cell corticosterone levels significantly increased in 50 micromol/L Ost treatment group after 24-and 48-h intervention (P < 0.05). Contents of corticosterone increased more obviously in 25 and 50 +/- mol/L Ost treatment groups after 48-h intervention, as compared with 24-h intervention (P < 0.01). After 24-h intervention, expression levels of Star, Cyp21a1, and Hsd3b2 genes were significantly up-regulated in 25 and 50 lLmol/L Ost groups (P < 0.05). Star gene expression was further enhanced after 48-h intervention (P < 0.05). However, Ost showed no effect on Cyp11a1 (P > 0.05). Additionally, gene expressions of Cyp11b1 and Cyp17a1 were significantly enhanced by 10, 25, and 50 pLmolIL Ost after treatment for 24 and 48 h (P < 0.05). Ost showed no obvious effect on Cyp11b2 and Hsd17b3 expressions.
CONCLUSIONOst could regulate adrenal cortex function and promote corticosterone synthesis and secretion through strengthening gene expressions of steroidogenic enzymes.

9.Effects of intranasal corticosteroids on radiated nasal mucosa of guinea pig.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2009;23(8):364-368
OBJECTIVE:
To observe histopathologic changes of irradiated guinea pigs' nasal mucosa treated with intranasal corticosteroids and to study the radioprotective effect of intranasal corticosteroids.
METHOD:
Fifty health guinea pigs nasal parts were performed irradiation by the WDVE-6MeV linear accelerator. They had accepted 5 Gy one time per week for three weeks through X-ray irradiating to establish the animal irradiation injury model. After that, they were divided into 2 groups randomly: the control group and the administration group and each group had 25 guinea pigs. The administration group received intranasal corticosteroids on the second day after three weeks irradiation, 5 animals per one group were sacrificed randomly at 1 W, 1 M, 2 M, 3 M, 4 M after administration, the histopathologic changes were observed under optical, scanning electron and transmission electron microscope respectively.
RESULT:
Using intranasal corticosteroids after irradiation, the early inflammatory reaction of the administration group was milder than the control group. With the drug being given constantly, the recovery of epithelial cell with irradiated damage was accelerated and the coverage rate of cilia went up obviously; After four months, the coverage rate of cilia had risen to 72.9%; But, for the control group, the coverage rate of cilia is only 50.2%. The atrophy of submucosal glandular organ was lessened and they displayed some extent secretory function. The reparation was accelerated as time went by.
CONCLUSION
Irradiation brought about serious injury on guinea pigs' nasal mucosa. But, the injury was lessen after using intranasal corticosteroids. Intranasal corticosteroids play the role of radioprotection for the irradiated nasal mucosa.

Functioning adrenocortical oncocytomas are extremely rare and most reported patients are 40-60 yr of age. To our knowledge, only 2 cases of functioning adrenocortical oncocytomas have been reported in childhood. We report a case of functioning adrenocortical oncocytoma in a 14-yr-old female child presenting with virilization. She presented with deepening of the voice and excessive hair growth, and elevation of plasma testosterone and dehydroepiandrosterone sulfate. She had an adrenalectomy. The completely resected tumor composed predominantly of oncocytes without atypical mitosis and necrosis. A discussion of this case and a review of the literature on this entity are presented.
