Objective To detect serum concentration of folate receptor alpha and to investigate its significance in the clinical application of patients with endometrial carcinoma. Methods Thirty-seven patients with endometrial carcinoma, 33 patients with endometrial hyperplasia and 10 healthy women were enrolled in this study. Sera were used to detect the the folate receptor alpha using an Enzyme-linked Immunosorbent Assay (ELISA) technique.The expression level of serum folate receptor alpha in different groups was analyzed. The correlation between the expression level of serum folate receptor alpha and age of patients, menopause, tumor morphology, myometrial invasion and clinical stage was was also analyzed in patients with endometrial carcinoma. Results Level of folate receptor alpha was successfully detected in serum of healthy women and patients with endometrial diseases. Level of folate receptor alpha in patients with endometrial carcinoma was much higher than that in patients with endometrial hyperplasia. Level of folate receptor alpha in patients with endometrial hyperplasia was also higher than that in the healthy controls, with significant difference (P < 0.05). In the endometrial carcinoma group,the levle of folate receptor alpha in serum was correlated with the clinical stage and myometrial invasion (P < 0.05), however, Level of folate receptor alpha was not correlated with the age of patients, menopause andtumor morphology(P > 0.05). Conclusion The Serum level of folate receptor alpha can be detected, and its expression will contribute to the diagnosis, treatment and predicting the prognosis of patients with endometrial carcinoma.

BACKGROUND:Bone cement used in the vertebroplasty treatment of osteoporotic vertebral compression fractures is nonabsorbable and has stronger intensity than normal bone tissue, which can cause further fractures of adjacent segments. OBJECTIVE:To investigate the short-term effect of vertebroplasty with artificial bone in the treatment of osteoporotic thoracolumbar fractures. METHODS:A total of 21 patients with osteoporotic vertebral compression fractures were enrol ed, including 7 males and 14 females, aged 61-89 years old. Al the patients were subjected to vertebroplasty with calcium sulfate injection. Visual analog scale and Oswestry Disability Index assessment were used before and at 0, 24, 48 weeks after treatment;meanwhile, X-ray and CT were used to observe the fil ing and leakage of artificial bone. RESULTS AND CONCLUSION:After treatment, al the patients showed improvements in the scores of visual analog scale and Oswestry Disability Index (P<0.01). X-rays and CT scans showed that there were three cases of leakage but without spinal cord and nerve compressions. After 3 months, most of the artificial bone was absorbed. These findings indicate that vertebroplasty with artificial bone can ease pain and improve living conditions of patients with osteoporotic vertebral compression fractures.

Objective To summarize reasonable therapeutic measures by analyzing the characteristics of tardive intestinal malrotation in childhood. Methods Clinical data of 23 definitely diagnosed cases of intestinal mal-rotation from 1998 to 2008 were studied retrospectively. Results All of 23 patients were processed through plain ab-dominal radiograph;9 were examined with barium meal;2 were examined with barium enema;20 were examined by abdominal Doppler and 13 were examined by abdominal computer tomography. There were 18 patients who got final diagnosis preoperatively and the rate of final diagnosis was 78.3%. All of the cases were cured with Ladd's operative method. Conclusion Because tardive intestinal malrotation has various clinical manifestations,it is more difficult to diagnose than congenital intestinal malrotation in children. The main causes of death are intestinal volvulus and/or necrosis. At present,surgery is a traditional therapeutic way. Ladd procedure is the main traditional way to treat mal-trotation.

We examined the effects of intracerebroventricular ( i. c. v) administration of adrenomedullin (ADM) on catecholaminergic neurons and the expression of c-fos gene in rat brain nuclei involved in cardiovascular regulation using double immunohistochemical method for Fos and tyrosine hydroxylase (TH). The results showed that: ( 1 ) Following icy administration of ADM (3 nmol/kg) , double-labeled neurons for Fos and TH were significantly increased in the area postrema ( AP), the nucleus of the solitary tract ( NTS), the nucleus paragigantocelluaris laterialis (PGL) and the locus coeruleus (LC). (2) Pretreatment with calcitonin gene-related peptide receptor antagonis CGRP8-37 (30 nmol/kg) significantly reduced the action of ADM (3 nmol/kg) in the brain. The present study suggested that ADM might activate the neurons of the brain nuclei involved in cardiovascular regulation, and supported the hypothesis that the central action of ADM were induced by activating the catecholaminergic neurons of brainstem nuclei involved in cardiovascular regulation, CGRP receptor might mediate the effects of ADM.
