Objective To investigate the differences in visceral fat area measured by bioelectrical impedance analysis in different sex and age groups, and explore the relationship between visceral fat area and other metabolic risk factors. Methods This study enrolled 72 in-patients in the department of cardiology in Peking University First Hospital between August, 2014 and October, 2014. The visceral fat area and the subcutaneous fat area were measured by DUALSCAN HDS-2000 in all patients. Results were compared between different sex and age groups and the relationship between visceral fat area and metabolic risk factors were analyzed. Resu1ts Male had larger visceral fat area than female [ ( 114. 04 ± 38. 27 ) cm2 vs. (92. 09 ±30. 57)cm2, P=0. 019], while female had larger subcutaneous fat areas than male [(223. 92 ± 73. 58)cm2 vs. (270. 35 ± 82. 13) cm2, P =0. 019] . Subcutaneous fat area and visceral fat area were positively correlated in both male ( r=0. 777, P﹤0. 001) and female ( r=0. 601, P=0. 002). There were no significant differences in visceral fat area among different age groups (P=0. 582). And visceral fat area had a positive correlation with body mass index (r=0. 748, P﹤0. 001), waist-hip ratio (r=0. 577, P﹤0. 001), abdominal circumference (r =0. 752, P ﹤0. 001) and HbA1c levels (r =0. 413, P =0. 001). Conc1usions There are sex differences in visceral fat area and subcutaneous fat area. The visceral fat area max be related to blood glucose levels and presence of diabetes.

AIM To explore the role of nitric oxide (NO) mediators in seizure behavior and the related expression of interlukin 6(IL 6). METHODS The IL 6 immunoreactivity (IL 6 ir) and behaviour were observed in kainic acid (KA) induced seizure following pretreatment with L nitroarginine( L NNA), a inhibitor of nitric oxide synthase(NOS), or the same number of moles of L arginine( L Arg). RESULTS The results showed that time dependent seizures were induced on animals after administration of KA (10 mg?kg -1 ), accompanied by the immediate enhancement of IL 6 ir in hippocampal structure, piriform area and cortex. The behaviors of rats were not markedly altered by chronic pretreatment with L NNA (50 mg?kg -1 ) or L Arg (40 mg?kg -1 ). However, after the administration of KA, the seizure behaviors were obviously different in the group of L NNA and L Arg respectively. Seizure was agrevated in the animals with L NNA pretreatment and many rats died at KA 3 hours, whereas seizure was alleviated after KA in the group of L Arg. IL 6 expression was apparently up regulated in some brain areas such as hippocampus in the group of KA pretreated with L NNA, but opposite effects appeared in the group pretreated with L Arg before KA injection. CONCLUSION These results indicate that endogenous NO mediators may alleviate the seizure behaviors and may down regulated the early expression of IL 6 in KA challenged seizure, but it the mechanism of the early expression of IL 6 with the homeostasis of endogenous NO mediator merits further study.nismoftheearlyexpressionofIL 6withthehome

OBJECTIVETo construct a three-dimensional finite element model of the upper airway and adjacent structure of an obstructive sleep apnea hypopnea syndrome (OSAHS) patient for biomechanical analysis. And to study the influence of glossopharyngeum of an OSAHS patient with three-dimensional finite element model during titrated mandible advancement.

METHODSDICOM format image information of an OSAHS patient's upper airway was obtained by thin-section CT scanning and digital image processing were utilized to construct a three-dimensional finite element model by Mimics 10.0, Imageware 10.0 and Ansys software. The changes and the law of glossopharyngeum were observed by biomechanics and morphology after loading with titrated mandible advancement.

RESULTSA three-dimensional finite element model of the adjacent upper airway structure of OSAHS was established successfully. After loading, the transverse diameter of epiglottis tip of glossopharyngeum increased significantly, although the sagittal diameter decreased correspondingly. The principal stress was mainly distributed in anterior wall of the upper airway. The location of principal stress concentration did not change significantly with the increasing of distance. The stress of glossopharyngeum increased during titrated mandible advancement.

CONCLUSIONA more precise three-dimensional finite model of upper airway and adjacent structure of an OSAHS patient is established and improved efficiency by Mimics, Imageware and Ansys software. The glossopharyngeum of finite element model of OSAHS is analyzed by titrated mandible advancement and can effectively show the relationship between mandible advancement and the glossopharyngeum.

AIMTo further explore the roles of endogenous nitric oxide (NO) or NO derivatives in complex partial seizures and generalized convulsions.

METHODSThe effect of pretreatment with L-nitroarginine (L-NNA), an inhibitor of nitric oxide synthase (NOS), or L arginine (L-Arg), a precursor of NO on kainic acid (KA)-induced seizure in rats and the changes in the concentration of NO2 -/NO- in the hippocampus were determined.

RESULTSThe rats appeared with wet dog shakes (WDS) at 15 min and then occurred generalized convulsions during 1 h to 3 h after administration of KA (10 mg/kg i.p.). However, the pretreatment of L-NNA (50 mg/kg) so dramatically promoted and enhanced KA-induced behavioral seizures that the latency of generalized convulsion was shorten dramatically, and the mortality was greatly high. In contrast, the pretreatment with L-Arg (40 mg/kg) markedly delayed or weakened KA-induced behavioral changes, such as increasing latency of WDS and generalized convulsion, shortening time o f seizure and none of animal died during observed time. The concentration of NO2- /NO3- in the hippocampus increased immediately at 30 min and remained to 7 d after the administration of KA. Compared with control group (pretreatment with NS), the concentration of NO2- / NO3- in the hippocampus apparently increased at 3 h and 3 d after the administration of KA in the rats with L-Arg pretreatment.

CONCLUSIONThe endogenous NO (NO or NO derivatives) mediators may play an important role against excitotoxin induced seizures in rats.

OBJECTIVETo investigate the effect(s) of interleukin-1beta (IL-1beta) on the activity of human growth hormone (hGH) gene promoter in rat pituitary GH3 cells and the molecular mechanism.

METHODSThe method of luciferase reporter gene was used. We firstly established stable GH3 cell line which contains hGH gene promoter -484-30 bp and luciferase reporter gene. After treating these cells with IL-1beta or IL-1beta plus various signaling transduction inhibitors, the concentration of GH in the medium and lysate of GH3 cells and luciferase activities in GH3 cells were measured to reflect the effect of IL-1beta on secretion and synthesis of GH and the promoter activity of the hGH gene and the molecular mechanism. Results IL-1beta (10-10(4)U/ml) increased secretion and synthesis of GH. IL-1beta at levels of 10(2)-10(4) U/ml promoted the luciferase expression in stable GH3 cells, and the maximal action was 1.61 times of the control (P < 0.001). Among the inhibitors of intracellular signaling transduction pathways, mitogen-activated protein kinases (MAPK) inhibitor PD98059 (40 micromol/L) and p38 MAPK inhibitor SB203580 (5 micromol/L) completely blocked the stimulatory effect of IL-1beta, and phosphoinositide 3-kinase (PI3-K) inhibitor LY294002 (10 micromol/L) partly blocked the induction of IL-1beta. Neither overexpression of Pit-1 nor inhibiting Pit-1 expression affected IL-1beta induction of hGH promoter activity. The stimulatory effect of IL-1beta was abolished following deletion of the -196 to -132 bp fragment.

CONCLUSIONSIL-1beta increases the activity of hGH gene promoter in rat pituitary GH3 cells. This stimulatory effect of IL-1beta appears to require the intracellular MAPK, p38 MAPK, and PI3-K dependent signaling pathways. The effect of IL-1beta requires the promoter sequence that spans the -196 to -132 bp fragment of the gene, but it is unrelated to Pit-1 protein.

OBJECTIVETo detect the level of transforming growth factor-beta1 (TGF-beta1), TGF-beta2, vascular endothelial growth factor (VEGF) and platelet-derived growth factor receptor-alpha (PDGFRalpha) in plasma and peripheral blood leukocytes in a hereditary hemorrhagic telangiectasia type 2 (HHT-2) family, and explore the implication of angiogenesis related proteins in HHT-2 pathogenesis.

METHODSThe diagnosis of the HHT-2 patient was based on clinical features and further confirmed by determining a C1231T mutation of activin receptor-like kinase 1 (ALK1) gene. Five other new members in this family were evaluated with ALK1 gene screening and clinical manifestation. Plasma level of TGF-beta1, TGF-beta2 or VEGF was measured by ELISA, and the expression of PDGFRalpha,TGF-beta1, and VEGF in peripheral blood leukocytes by flow cytometry combined with direct or indirect immunofluorescence.

RESULTSNo C1231T mutation was detected in exon 8 of ALK1 gene in the 5 new members. Plasma TGF-beta1 and TGF-beta2 concentration in 3 affected HHT case was (16 954 +/- 3 709) ng/L and (11 548 +/- 2 611) ng/L, respectively, compared with that of normal control, the difference was not significant (P > 0.05). VEGF concentration in the 3 HHT patients, 6 unaffected family members and 6 normal controls was (179.2 +/- 22.0) microg/L, (149.8 +/- 22.7) microg/L and (132.9 +/- 21.0) microg/ L, respectively. Plasma VEGF level in HHT patients was significantly higher than that in normal subjects (P < 0.025). Peripheral leukocyte PDGFRalpha and VEGF in HHT patients and unaffected family members were markedly higher than that of normal control (P < 0.05 and P < 0.02), while TGF-beta1 distribution was similar in HHT patients and normal subjects.

CONCLUSIONCompared with normal controls there is no difference in plasma TGF-beta1 concentration on peripheral leukocytes of HHT patients. Plasma VEGF concentration or leukocytes VEGF expression in HHT is significantly higher than that of normal subjects. Leukocytes PDGFRalpha expression in HHT is significantly higher than that of normal control. These changes may be associated with a compensable mechanism in HHT.
