    Objective Investigate the relationship between central obesity, which is evaluated by waist circumference (WC) and waist-to-hip ratio (WHR), peripheral obesity, which is measured by body mass index (BMI), and ventricular repolarization inconsistencies. Methods Standard 12-lead ECGs of 2045 adults from Heilongjiang Province were measured with Philips Trim II electrocardiograph. QTc were calculated and corrected by Bazett formula. We used the criterion that QTc>440ms was abnormal. Results QTc and abnormal rates increased with age or obesity indices in both male and female. Females' QTc and abnormal rates were significantly higher than the males'. Logistic regression analysis showed that age, gender, heart rate and systolic blood pressure (SBP) had significant effect on QTc abnormal. BMI, WC and WHR also had significant effect on QTc abnormal. WC was the most significant one. Conclusion Obesity is a significant and independent factor to QTc and abnormal rates. Obesity is significantly correlated with ventricular repolarization inconsistencies. Central obesity has more advantages in weighing adults' ventricular repolarization inconsistencies than peripheral obesity.

    Objective we're trying to determine the cis-element in the regulation of rat ALAS-1 promoter by PGC-1β. Methods Transient transfection with PGC-1β was done in Hep G2, then dual-luciferase reporter assay was performed to investigate fold activity of rat ALAS-1 promoter when over-expressing PGC-1β. Reconstructing ALAS-1 promoter reporters including a series of 5'-deletions and cis-element mutations, dual-luciferase reporter assay was performed to assay NRF-1 binding sites in rat ALAS-1 promoter. We construct adenoviral PGC-1β and adenoviral siRNA of NRF1 and isolate rat primary hepatocytes and assay the effects of PGC-1β on the rat ALAS-1 transcription. Results Overexpression of PGC-1β stimulates the transcription of ALAS-1 in Hep G2 cells, while over-expressing NRF-1 alone had no stimulation. We constructed NRF-1 binding site mutated ALAS-1 promoter, the promoter activity was obviously diminished by overexpression of PGC-1β. PGC-1β promotes the transcription of ALAS-1 in the rat primary hepatocytes. When we use the siRNA to interfere the expression of NRF-1, the stimulating effect of PGC-1β on the ALAS-1 was attenuated. Conclusion PGC-1β promoting the transcription of ALAS-1 is mainly by NRF-1 in Hep G2 cells and rat primary hepatocytes.

    Objective To detect the regulation of PGC-1α and ERRα on mouse SHP transcription in human hepatoma HepG2 cells, and to determine the cis-element involved in the regulation of ERRα on SHP promoter. Methods Transient transfection with ERRα and/or PGC-1α in HepG2 and human embryonic kiney 293A cells, then dual-luciferase reporter assay was performed to investigate fold activity of mouse SHP promoter reporter when overexpressing ERRα and PGC-1α. Reconstructing SHP promoter reporters including a series of 5′-deletions and cis-element mutations, dual-luciferase reporter assay was performed to screen ERRα binding sites in HepG2 cells. Results Coexpression of ERRα and PGC-1α stimulates the transcription of SHP in HepG2 and 293A cells. Five potential ERRα binding sites were identified by analyzing the sequence of SHP promoter. In the dual-luciferase reporter assay with 5′-deletions of promoter, three of five potential elements were demonstrated to be concerned with transcriptional regulation of ERRα. Furthermore, it was demonstrated that two sites of them involve in regulating SHP transcription by ERRα and PGC-1α using mutational promoter luciferase reporter assay, the other one may participate in the basal level transcription of SHP. Conclusion ERRα is a novel pathway that regulates SHP gene transcription in HepG2 cells besides FXR and ERRγ, only when the coactivator PGC-1α is in presence.

    Objective To test whether cardiac progenitor cells (CPCs) which induced by bone morphogenetic proteins9 (BMP9) can improve the heart function of the rats with myocardial infarction. Methods CPCs were infected by AdBMP9 which express green fluorescent protein. After twenty-four hours, the expression of BMP9 of infected CPCs were examined by semi-quantitative RT-PCR. Then, infected CPCs by AdBMP9 were injected into the infracted heart. The hearts were collected, after postoperative four weeks. The change of CPCs morphology was observed by HE staining and immunofluorescent analysis to investigate the expression of cardiac-specific structural proteins alpha myosin heavy chain(α-MHC) andα-Actin of the implanted CPCs .The cardiac infarct size was detected by Masson staining. Heart function was examined by echocardiography, in preoperative and postoperative four weeks. Result After twenty-four hours, the expression of BMP9 of CPCs infected by AdBMP9 improved significantly(P﹤0.05). The result of HE staining and immunofluorescent showed that the grafted-CPCs could fuse with the normal cardiomyocytes and expressed the cardiac-specific proteinsα-MHC and α-Actin, in the four weeks after transplantation. But the expression of cardiac-specific structural proteins is lower than the normal cardiac tissue(P﹤0.05). In the postoperative four weeks, the implanted CPCs can reduce the sizes of infracted obviously(P﹤0.05)and which can be promoted by BMP9(P﹤0.01).The result of heart function is similar with the Masson staining. Conclusion CPCs induced by BMP9 can improve the heart function of the rats with myocardial infarction.

Methods Restrospective analyze 38 cases of CMV infection in healthy adult inpatients without obvious organic disease from 1995 to 2008 in PUMC hospital,review their clinical manifestation, labortary test, treatment and prognosis. Results The features of CMV infection in adults without obvious organic disease are varied. Most common clinical feature is fever(68.4%), other include enlarged lymph nudes(28.9%), liver(34.2%) and spleen(44.7%) and atypical lymphocytes in peripherial blood. In acute phase of diseases, T cell subset showed reversed CD4/CD8 cell ratio, significantly increased amount of subset of CD8+ T cell(CD8+CD38+)(732±760 vs. 271114, P=0.024). Decreased NK cell was also found(125±146 vs. 371±196, P=0.00). Prognosis is poor in patients with mutiple organs dysfunction, Ganciclovir is effective. Conclusion: CMV diseases in healthy adult are with varied features and may cause severe diseases, which should be pay great attention.
