Objective To discuss the influence of coronary computed tomography angiography(CCTA)on correctness of assessing revascularization in patients with coronary artery disease. Methods A retrospective study method was conducted,605 cases underwent CCTA before coronary angiography(CAG)from 2008 to 2009 in Chinese PLA General Hospital were selected as CCTA before CAG group,and meanwhile 616 cases examined by CAG directly were selected as direct CAG group. Patients with multiple procedures of CAG were excluded. The proportions of various treatment strategies were compared,including per-cutaneous coronary intervention(PCI),coronary artery bypass grafting(CABG),medical therapy(MT),normal rate of CAG and the correctness of assessing revascularization between the two groups. Results The comparison between the baseline of the two groups showed that in the CCTA before CAG group,there were more severe lesions than those in the direct CAG group,such as Syntax score(11.31±8.90 vs. 10.23±9.73,P<0.05). Compared with direct CAG group,the triage of PCI and CABG in the CCTA before CAG group was significantly increased〔PCI:65.3%(395/605)vs. 57.1%(352/616),CABG:16.5%(100/605)vs. 3.4%(21/616)〕,while the percentages of medical treatment and normal CAG were obviously reduced〔medical treatment:11.7%(71/605)vs. 19.3%(119/616),normal rate of CAG:6.4%(39/605)vs. 20.1%(124/616),all P<0.01〕. With the guidance of CCTA,the correctness of assessing revascularization was increased〔81.8%(495/605)vs. 60.6%(373/616),P<0.01〕. Conclusion Compared with the direct induction by CAG,the CCTA examination carried out before CAG is capable of increasing the rate of correctness in the determination of revascularization in coronary heart diseases.

Objective To assess the relationship between coronary plaques and risk factor of coronary heart disease in a asymptomatic population.Methods A total of 604 in-patients who received coronary computerized tomography angiography (CCTA) during January 1 th,2010 and April 1 th,2011 were enrolled in this study and assigned to the non-lesion group (0),mild lesion group (0 ＜ score ≤ 5) andmoderate-severe lesion group (＞ 5) according to the third quartile of CCTA score.Clinical data including physical examination,laboratory test,ultrasound sonogram and discharge diagnoses were collected and compared between the groups.Multivariable linear regression and bivariate logistic regression were performed to find out the main risk factors of coronary heart disease.ROC curve was drawn to estimate the diagnostic value of coronary lesions.Results There were 240 individuals in the non-lesion group,271 in the mild lesion group,93 in the moderate-severe lesion group.Multivariable linear regression indicated Y =-6.56 +3.22 × mean carotid intima-media thickness (cIMT) + 1.106 × male + 0.597 × low-density lipoprotein cholesterol (LDL-C) + 0.116 × age-1.596 × high-density lipoprotein cholesterol (HDL-C).Bivariate logistic regression and ROC curve showed that mean cIMT was the main risk factor of coronary heart disease (odds ratio (OR) =7.19,ROC =0.730,P=0.00,95％ confidence interval (CI):0.68 to 0.78).Furthermore,major coronary lesions were located in the LAD (20.8％) and was soft plaque (42.5％).Conclusion In this investigation,60.2％ of the asymptomatic patients showed plaques in CCTA.Age,cIMT,LDL-C and HDL-C may be predictive to moderate to severe coronary artery lesions.

Objective To isolate mesenchymal stem cells(MSCs) from the mobilized peripheral blood and transdifferente them into cardiomyocytes for establishing an non-invasive cell source of stem cell transplantation for myocardial infarction therapy.Methods To granulocyte-colony stimulating factor((30 ?g/kg?day)) was injected into New Zealand White rabbits subcutaneously for 5 days,then MSCs were isolated from peripheral blood.After treatment with 5-azacytidine for 24 hours,the cultured cells were evaluated by immunohistochemical staining for actin,desmin and cardiac-specific troponin T(cTNT).Results After treatment with 5-azacytidine,the MSCs from the mobilized peripheral blood showed spindle-like and multinucleation,some cells aggregated and formed a ball-like appearance at 2 weeks.The ball-like cells and some spindle-like multinuclear cells were found with positively staining of actin,desmin and cTNT.Conclusion MSCs can be isolated from the mobilized peripheral blood and transdifferented into cardiomyocytes in vitro,suggesting that MSCs from the mobilized peripheral blood may be a new and non-invasive cell source of stem cell transplantation in myocardial infarction therapy.

Objective To observe the impairment of different doses of cyclosporine A (CsA) to the rat myocardial tissue to offer scientific evidence for the long-term safe application of CsA in heart transplantation. Methods Eighty-four female Wistar rats, each weighing of (200 ± 25)g, were randomly divided into 12 groups. On days 7,14,21 after a constant peritoneal injection of CsA(0,5,10,15 mg/kg) and 1 ml physiological saline in control group, the rats were put to death, the rat myocardial tissue taken, to observe the pathologic and structural changes of the tissue cells under light microscope and electron microscope. The contents of rat myocardium tissue malondialdehyde(MDA) and superoxide dismutase(SOD) were measured;cardiomyocyte apoptosis was detected and accounted, apoptosis index(AI) was measured with the method of TUNEL. Results Small dose of CsA(5 mg/kg)had no obvious effects on cardiac tissue, in CsA groups of 10 mg/kg and 15 mg/kg, under the light microscope, there appeared edema, degeneration and necrosis of myocardium, part of cardiac myocyte had different level cavity;under the electron microscope, there appeared mitochondria damage, nucleus shrinkage and chromatic margination, part of cardiac myocyte had focus cavity. There was dilated endoplasic reticulum in the sarcoplasm. The effects of different time and dose on MDA content of rat myocardium tissue had statistical significance (F = 6.37,10.15, both P < 0.05). Interaction between time and dose existed statistical significance (F=7.14, P< 0.05). The MDA contents of CsA group of 10 mg/kg and 15 mg/kg were [(2.29 ± 0.18), (3.10 ± 0.45), (2.57± 0.37)nmol/L] and [(3.09±0.63), (3.32 ±0.52), (3.34 ± 0.29)nmol/L] on days 7,14,21 after a constant peritoneal injection of CsA, which were obviously higher than the control group [(1.98 ± 0.20), (2.04 ± 0.52), (1.99 ± 0.26) nmol/L, all P < 0.05], respectively. The effects of different time and dose on SOD activity of rat myocardium tissue had statistical significance(F = 8.43,11.69, both P < 0.05). Interaction between time and dose existed statistical significance(F = 9.86, P < 0.05). The SOD activity of CsA groups of 10 mg/kg and 15 mg/kg were (15.95 ± 1.00), (12.74 ± 1.31), (14.01 ± 0.81)nmol/L and (13.04 ± 1.01), (14.68 ± 0.81), (14.01 ± 0.63)nmol/L on days 7,14,21 after a constant peritoneal injection of CsA, which were obviously higher than the control group [(10.38 ± 0.80), (9.73 ± 0.58), (10.20 ± 0.26)nmol/L, all P < 0.05], respectively. Apoptosis nucleus appeared huffy or brown under the light microscope. The effects of different time and dose on AI of rat myocardium tissue had statistical significance (F = 10.02,20.46, both P < 0.05). Interaction between time and dose existed statistical significance (F = 15.73,P < 0.05). The AI of CsA groups of 10 mg/kg and 15 mg/kg were (6.91 ± 0.70)%, (11.10 ± 2.05)%,(19.81 ± 5.00)% and (11.02 ±2.02)%,(15.51 ± 1.31)%,(33.40±6.60)% on days 7,14,21 after a constant peritoneal injection of CsA, which were obviously higher than the control group [(4.40 ± 0.13)%, (4.60± 1.20)%, (5.20 ± 1.10), all P < 0.05] and CsA group of 5 mg/kg [(4.60 ± 0.10)%, (5.00±2.11)%, (5.43± 1.11)%, all P < 0.05], respectively. Conclusion Small dose of CsA has no obvious effects on cardiac tissue, but large dosage can induce myocyte apoptosis and damage by causing oxidative stress;after implantation, attention should be paid to cardiac impairment due to constant large dosage of CsA.

Objective To explore the reasons why patients with Keshan disesse complicated with hypertension and their interaction in Fuyu County, Heilongjiang Province. Methods Fifty-three patients with Keshan disease were investigated in January, April and July in 2007. Blood pressure was measured and the risk factors of hypertension were investigated. According to the diagnostic criteria of hypertension, patients were divided into hypertension group and non-hypertension group, and then the risk factors of hypertension, as well as the course of Keshan disease, were compared between the two groups. The risk factors include age, gender, family history of hypertension, salt intake in diet, smoking, drinking and obesity. Results The age of hypertension group[(57.83±8.89)years] was significantly higher than that of non-hypertension group [(51.53 ± 9.43)years, t = 2.3630, P < 0.05) ;while the course of Keshan disease in non-hypertension group [(31.63 ± 8.66)years] was notably longer than that in hypertension group [(25.08±11.41)years, t = 2.0224, P < 0.05] ;No statistically significant difference in gender, family history of hypertension, salt intake in diet, smoking, drinking and obesity was observed between the two groups(χ2 = 0.0072,0.1779,0.0029,0.1555,0.119,0.7679, all P > 0.05). Conclusions Age might be an important factor in patients with Keshan disease accompanied by hypertension, and the role of other risk factors of hypertension should not be overlooked;whether Keshan disease and hypertension can affect each other needs further investigation.
