Objective:To explore bromodomain and extra-terminal (BET) inhibition in the regulation of vascular endothelial cells activation and early atherosclerosis formation and its potential molecular mechanisms.Methods:1.Human umbilical vein endothelial cells (HUVEC) and mouse heart endothelial cells (MHEC) were isolated,and tumor necrosis factor α (TNFα) was used to activate in flammatory genes transcription in the presence or absence of JQ1,a specific BET inhibitor.The groups are as follows:(1)Normal control group;(2) TNFα(25 ng/mL)group;(3) TNFα+JQ 1 group.The gene mRNA and protein expression of inflammatory cytokines were measured by both real-time PCR and flow cytometry (FCM).2.LDL receptor-deficient (LDLR-/-) mice were randomly divided into 2 groups:JQ1 group (n=8,JQlintraperitoneal,50 mg/kg,daily) and control group (n=8,DMSO,daily).After 8 weeks feeding with high cholesterol diet,vascular cell adhesion molecule-1 (VCAM-1) expression in aortic arch was measured by immunohistochemistry.The activity of nuclear factor kappa B (NF-κB) signaling was monitored by 5XκB luciferase reporter assay in HEK293.Results:TNFα dramatically induced the mRNA and protein expression of inflammatory genes and JQ 1 significantly downregulated the induction of them (E-selectin,P-selectin,VCAM-1,IL-8)(P＜0.01).Immunohistochemistry detection indicated that JQ1 significantly downregulated the expression of VCAM-1 in aortic arch induced by 8 weeks high cholesterol diet feeding comparing to control group.In addition,BET bromodomain inhibition downregulated TNFα upregulated NF-κB transcriptional activity (P＜0.01).Conclusions:Our study demonstrated that BET bromodomain was involved in NF-κB mediated inflammatory genes expression;inhibition of BET bromodomain suppressed vascular endothelial activation in vitro,and attenuated early atherogenesis in vivo.

Objective To identify lung adenocarcinoma-associated antigens by using Serologic Proteome Analysis(SERPA),an approach which combined conventional proteome analysis with serological screening.Methods SERPA of four human lung adenocarcinoma tissues were performed.The Western blot imaging films which reacted with autologous patient serum and with control normal serum were obtained and the differential reacting protein spots were recognized.Results Well-resolved,reproducible 2-DE Western blot imaging films of human lung adenocarcinoma reacted with autologous patient sera and the control sera were obtained.Totally(27?5) differentially expressed proteins which only were reactive with lung adenocarcinoma patient sera were found.Some differentially expressed proteins were identified by peptide mass fingerprint(PMF).Some of the proteins were the products of oncogenes,and others were involved in the regulation of cell cycle and signal transduction.Conclusion These results will provide scientific foundation on screening the molecular biomarker for the diagnosis,treatment,and prognosis of the lung adenocarcinoma.

OBJECTIVETo study the correlation between the inflammatory factors in the serum and the induced sputum and the hypothalamic-pituitary-adrenal (HPA) axis function in advanced lung adenocarcinoma patients of different syndromes.

METHODSTotally 71 patients with advanced lung adenocarcinoma were assigned to three groups according to syndrome differentiation, i.e., Shen-yang deficiency (SYD) group (28 cases), Fei-qi deficiency (FQD) group (23 cases), and yin deficiency fire excess (YDFE) group (20 cases). Another 41 healthy subjects were enrolled as the normal control group. Sputum was induced and blood samples were collected for measurement of cytokines including tumor necrosis factor alpha (TNF-alpha), transforming growth factor beta (TGF-beta), interleukin-6 (IL-6), and interferon gamma (INF-gamma). The cytokine assay was performed using Bio-Plex Pro multi assay technology. 24-h collection of urine was performed and salivary samples of the diurnal rhythm profiles [including urinary free cortisol (UFC), urinary 17-hydroxycorticosteroids (17-OH), urinary 17-ketosteroid (17-KS), and cortisol in the serum and saliva] were obtained for assessment of the HPA axis activity.

RESULTSA higher level of serum IL-6 and a lower level of 24-h UFC and 17-OH were found in the SYD group (P < 0.05). The urinary 17-KS was obviously lower in the SYD group than in the normal control group and the YDEE group (P < 0.05). Compared with the FQD group and the normal control group, a higher serum level of TNF-alpha and a lower level of IFN-gamma were found in the SYD group and the YDFE group (P < 0.05). The TNF-alpha and TGF-beta levels in the induced sputum obviously increased in the SYD group (P < 0.05). The IFN-gamma level in the induced sputum obviously decreased in the YDFE group (P < 0.05). The serum and salivary cortisol obviously decreased from 8: 00 am to 8:00 am the next morning in the SYD group (P < 0.05). The serum cortisol level was negatively correlated with serum TNF-alpha (r = -0.26, P = 0.03) and serum IL-6 (r = -0.25, P = 0.03). The salivary cortisol level was negatively correlated with IL-6 in the induced sputum (r = -0.29, P = 0.02). The serum IFN-gamma was positively correlated with urinary 17-OH (r = 0.21, P = 0.03).

CONCLUSIONSThe inflammatory factors of advanced lung adenocarcinoma patients of SYD syndrome were up-regulated, with the most obvious decreased or disarranged HPA axis functions. The levels of IL-6, TNF-alpha, and IFN-gamma were closely correlated with the HPA axis functions. The transformation from qi deficiency, yin deficiency to Shen-yang deficiency existed in lung adenocarcinoma patients. The levels of IL-6, TNF-alpha, and IFN-gamma in the serum and the induced sputum, as well as the HPA axis functions are important indices for microscopic syndrome typing of lung adenocarcinoma.

OBJECTIVETo explore factors related to pandemic influenza A (H1N1) virus infection among healthcare workers.

METHODSH1N1 influenza confirmed cases of health workers in hospital of Beijing from Aug 30th 2009 to Jan 31st 2010 were included. A 1:4 matched case-control study was conducted with 54 healthcare workers who were infected by influenza A(H1N1) virus and 216 matched controls who were not infected. Face-to-face interview with questionnaires was used to collect information of work and family aspects of the study participants. Conditional logistic regression was used to analyze the H1N1 infection factors.

RESULTSThe age was 29.6 ± 7.4 years old and male subjects accounted for 17.4% (47/270). There were 5.6% (3/54) and 34.4% (74/216) of the cases get the influenza A (H1N1) vaccine immunization separately in the case group and control group. Among 18.5% (10/54) and 40.1% (88/216) of the cases and controls used high protection level masks during the epidemic. Besides, 33 (61.1%)and 161 (74.5%) cases lengthening the time of mask wearing separately. There were 13 (24.1%) and 85 (39.4%) cases using disposable tissue to clean hands in the case group and control group, 24 (44.4%) and 46 (21.3%) cases feel they were much easier to get infected in respiratory disease than others based on experience in the case and control group. Univariate analysis showed that factors such as using disposable tissue to clean hands (OR = 0.15, 95%CI = 0.04 - 0.57), lengthening the time of mask wearing (OR = 0.43, 95%CI = 0.20 - 0.92), using high protection level masks (OR = 0.26, 95%CI = 0.11 - 0.58), getting influenza A (H1N1) vaccine immunization (OR = 0.04, 95%CI = 0.01 - 0.32), much easier to get infected in respiratory disease than others based on experience (OR = 2.85, 95%CI = 1.44 - 5.62), were all associated with influenza A (H1N1) infection. Results of multivariate logistic regression analysis showed that variables such as history of influenza A (H1N1) virus immunization (OR = 0.18, 95%CI = 0.06 - 0.51), using high protection level masks (OR = 0.05, 95%CI = 0.01 - 0.35), much easier to get infected in respiratory disease than others based on experience (OR = 3.69, 95%CI = 1.58 - 8.63) were all correlated to influenza A (H1N1) infection.

CONCLUSIONSFactors such as history of influenza A (H1N1) vaccine immunization, using high protection level masks and improving respiratory health can protect healthcare workers from infection of influenza A (H1N1).

OBJECTIVETo study the expression of histone acetyltransferases (HATs) and histone deacetylases (HDACs) in children with tetralogy of Fallot (TOF), and to investigate the role of histone acetylation and acetylation-related enzymes in the pathogenesis of TOF.

METHODSMyocardial tissue samples in the TOF group were obtained from 46 children with TOF who underwent radical operation, and myocardial tissue samples in the control group were obtained from 16 children who suffered accidental deaths and had no cardiac anomalies as shown by autopsy. The acetylation of H3K9, H3K18 and H3K27 was evaluated by immunohistochemistry. The mRNA expression of HATs and HDACs in the myocardium was measured by real-time PCR. The correlation between mRNA expression of HATs and HDACs and histone acetylation was analyzed.

RESULTSCompared with the control group, the TOF group showed significantly increased acetylation of H3K9 (P=0.0165) and significantly decreased acetylation of H3K18 (P=0.0048) and H3K27 (P=0.0084). As to 4 HATs and 6 HDACs, the mRNA expression of EP300 and CBP was significantly higher in the TOF group than in the control group (P=0.025; P=0.017), and there was no significant difference in the mRNA expression of other HATs and HDACs between the two groups. The correlation analysis revealed a positive correlation between H3K9 acetylation and mRNA expression of EP300 (r=0.71, P<0.01) and CBP (r=0.72, P<0.01).

CONCLUSIONSUpregulated mRNA expression of EP300 and CBP may be associated with increased H3K9 acetylation, suggesting that EP300 and CBP might affect cardiac development by regulating H3K9 acetylation.
