Objective To examine the effects of intracerebroventricular administration of adrenomedullin (AM) on the expression of Fos and spontaneous electric activity of area postrema (AP) neurons in sino-aortic denervated rats. Methods To determine the expression of Fos and the spontaneous electrical activity of AP neurons in male Sprague-Dawley rats by immunohistochemistry. Results Following Intracerebroventricular administration of AM (1 nmol/kg, 3 nmol/kg), Fos-like immunoreactive (Fos-LI) neurons and the discharge rate of AP neurons markedly increased. Pretreatment with calcitonin gene-related peptide(CGRP) receptor antagonist CGRP8-37 (30 nmol/kg) significantly inhibited the effects of AM (3 nmol/kg). Conclusion AM may activate the neurons in AP via CGRP receptors.

Objective To explore the expression and significance of hsa-miR-181a (miR-181a) in can-ceration progression of endometrial carcinoma. Methods A total of 75 formalin-fixed paraffin-embedded tissue specimens were studied in this study , of which , 13 were normal endometrium , 18 were endometrial hyperplasia , 44 were endometrial carcinoma. After total RNA had been extracted , real-time PCR was applied to detect the ex-pression level of miR-181a in endometrial tissue in each group. Results miR-181a expression in formalin-fixed paraffin-embedded tissue specimens can be detected. Expression of miR-181a in endometrial carcinoma was high-er than that in endometrial hyperplasia , its expression in endometrial hyperplasia was also higher than that in normal endometrium, and the difference was statistically significant (P < 0.05). The expression of miR-181a in endometrial carcinoma was associated with FIGO stages (P < 0.05). Conclusion The up-regulation of miR-181a expression in women with endometrial carcinoma may play the role of oncogenes. Abnormal expression of miR-181a is probably associated with the occurrence and development of endometrial carcinoma.

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.

Objective To investigate the correlations between HLAⅡgene polymorphism and the development of Mycoplasma pneumoniae pneumonia ( MPP ) in children and to identify the susceptibility genes and protective genes for MPP for further elucidating the pathogenesis of MPP and providing the guid-ance for researches on gene therapy for MPP. Methods Genotypes of HLAⅡgene ( HLA-DQA1 and HLA-DRB1) in 60 children with MPP and 30 healthy children were detected by using sequence specific primer polymerase chain reaction ( SSP-PCR) . The haplotype frequencies, linkage disequilibrium and correlations with MPP were analyzed by using Arlequin software and Chi-square test. Results The frequencies of HLA-DQA1*0201/*0301 in children with MPP (35. 83%/30. 00%) were higher than those in healthy children (16. 67%/8. 33%) (χ2=12. 139, P<0. 05, OR=5. 059;χ2=15. 142, P<0. 05, OR=7. 500). However, the frequency of HLA-DQA1*0401 in children with MPP decreased to 12. 50% as compared with 40. 00%in healthy children (χ2=24. 638, P<0. 05, OR=0. 083). The frequencies of HLA-DRB1*07/*15 in children with MPP increased to 38. 33%/30. 00% as compared with 20. 00%/16. 67% in healthy children (χ2=11. 735, P<0. 05, OR=4. 929; χ2=5. 692, P<0. 05, OR=3. 000). But the frequency of HLA-DRB1*11 dropped to 15. 00% as compared with 43. 33% in healthy children (χ2=19. 448, P<0. 05, OR=0. 087). Conclusion HLA-DQA1*0201, HLA-DQA1*0301, HLA-DRB1*07 and HLA-DRB1*15 might be the susceptibility genes for MPP in children, while HLA-DQA1*0401 and HLA-DRB1*11 were probably associated with the resistance to MPP. No extensive linkage disequilibrium was found between HLA-DQA1 and HLA-DRB1.
