Objective To investigate the effect of different etiology on the serum level of carbohydrate antigen 125 (CA125) in elderly patients with chronic congestive heart failure (CHF), and to assess any correlation of CA125 with serum level of B-type natriuretic peptide (BNP). Methods The 155 aged patients with New York Heart Association (NYHA) class Ⅲ or Ⅳ were enrolled and grouped into four reasons of hypertension, coronary heart disease (CHD), cardiomyopathy and other reasons, and 25 healthy old persons as control.CA125 and BNP levels were measured by automatic chemiluminescent immunoassay and enzyme immunoradiometric assay, respectively. Results CA125 level in patients with CHF was (83.4±6.6)U/L for hypertension, (36.8±1.4)U/L for CHD, (38.1±1.6)U/L for cardiomyopathy and (38.4±1.4)U/L for other reasons, which significantly higher than for healthy controls [(14.3±1.15) U/L, P＜0.05].Especially, CA125 level in hypertension group was notable higher than in other reasons of group (P＜0.05), and was positively related to BNP level (r=0.67,P＜0.05). Conclusions Serum CA125 level is a predictor for clinical pathogen of CHF.Therefore, it may be a useful additional marker for the evaluation of clinical treatment of these patients

OBJECTIVE: To evaluate changes of VEGF in skin after blunt injury. METHODS: The rats of injury groups were subjected to skin blunt injury by free-falling iron hammer. The samples taken at 1 h, 3 h, 6 h, 12 h, 1 d, 3 d, 5 d, 7 d, 9 d after injury were studied by immunohistochemistry and MIAS image analysis system. RESULTS: In the skin of normal control group the expression level of VEGF was low. The increase of VEGF could be observed at 1 day after injury, reached peak at 7 days and declined at 9 days. CONCLUSION Blunt injury in the skin could induce the expression of the VEGF. Moreover, the change pattern of VEGF level was quite regular with time and could be used to estimate the time after skin injury.

Objective To construct luciferase reporter plasmids of truncated fragments of different lengths of human guanylate binding protein 5(GBP5)gene promoter and analyze the transcriptional activity of each fragment to determine the core regulatory region.Methods GBP5promoter sequence was amplified by PCR,truncated into five fragments of different lengths and connected to pGL3-basic plasmid.The constructed recombinant plasmids pGL3-GBP5-11/21/31/41/51were transfected into 293FT cells and detected for luciferase activity.The binding sites of transcription factors in GBP5promoter region were predicted by JASPAR software,and Yin-Yang transcription factor 1(YY1)targeting the core regulatory region was selected and verified for the transcriptional regulatory activity.The CDS sequence of YY1 was amplified by PCR to construct the overexpression plasmid pIRES2-EGFP-YY1,which was then co-transfected to 293FT cells with plasmids pGL3-GBP5-21(-1 623 ～ +47 bp)and internal reference plasmid pRL-CMV,and detected for luciferase activity to analyze the regulation of transcription factor YY1 on GBP5 promoter activity.Results Colony PCR and double enzyme digestion identification proved that the plasmid of human GBP5 promoter reporter gene was correctly constructed;JASPAR software predicted that there were multiple transcription factor binding sites such as STAT1,YY1 and Foxp3 in GBP5promoter region.Double luciferase activity assay showed that pGL3-GBP5-21(-1 623 ～ +47 bp)showed the highest promoter activity,while the promoter activity of pGL3-GBP5-41(-520 ～ +47 bp)decreased significantly,suggesting that the core region of GBP5 promoter was located at upstream-1 623 ～-520 bp of 5 'UTR;Overexpression of YY1 significantly activated the GBP5 promoter activity and regulated the expression of GBP5.Conclusion The core regulatory region of human GBP5 promoter was located in upstream-1 623 ～-520 bp of the 5 'UTR,with a binding site of transcription factor YY1 existing in this region.Meanwhile,overexpression of YY1 significantly effected the activity of GBP5 promoter.

OBJECTIVETo investigate the mRNA and protein expressions of 11beta-Hydroxysteroid dehydrogenase type 2 (11betaHSD2) in patients with atrial fibrillation.

METHODSRight and left atrial lateral wall tissue samples were obtained during mitral/aortic valve replacement operation from 25 patients with rheumatic heart valve disease (12 in sinus rhythm and 13 in chronic atrial fibrillation). Realtime quantitative PCR and Western blot were used to determine the mRNA and protein expressions of 11betaHSD2 in atria specimens. The distribution of 11betaHSD2 in human atrial tissue was analyzed by specific immunohistochemical staining. Echocardiography examination was performed before operation.

RESULTSThe left atrial diameters were significantly higher in the atrial fibrillation group as compared to sinus rhythm group (P < 0.01). Similarly, mRNA expression of 11betaHSD2 (0.86 +/- 0.14 vs 0.33 +/- 0.12 in right atria, 0.95 +/- 0.15 vs 0.37 +/- 0.10 in left atria, all P < 0.01) and protein expression of 11betaHSD2 (1.18 +/- 0.64 vs 0.71 +/- 0.21 in right atria, P < 0.01; and 1.36 +/- 0.58 vs 0.85 +/- 0.15 in left atria, P < 0.05) were also significantly upregulated in atrial fibrillation groups than those in sinus rhythm groups. The mRNA and protein expressions of 11betaHSD2 were similar between left atria and right atria both in fibrillation and sinus groups (all P > 0.05). The special immunohistochemical staining demonstrated that 11betaHSD2 was abundant in the human atrial myocardium and located mainly in the cytoplasm.

CONCLUSIONThese findings suggested that upregulated 11betaHSD2 might be associated to the development and persistence of atrial fibrillation.
