Objective To evaluate the safety and efficacy of bone marrow cells(BMCs) transplantation on the improvement of cardiac function and myocardial perfusion in patients with old myocardial infarction. Methods and Results A total of 10 patients with anterior wall myocardial infarction were transplanted with autologous mononuclear BMCs through an infusion catheter which was placed with the tip in the left anterior descending coronary artery after coronary angiography and interventional therapy if necessary. After 3 months of follow-up, a significant increase of left ventricular ejection fraction(LVEF) determined by ultrasonic cardiography was found (54.5%?6.5% vs. 45.3%?9.8% before transplantation, P=0.003); 201-thallium scintigraphy (SPECT) showed that ventricular myocardial perfusion was significantly improved as the semiquantitative score of the immediate and delayed myocardial perfusion defects decreased from 29.5?5.8 and 28.6?6.3 to 23.9?5.7 and 23.0?6.1prospectively (both P

Results Initial success (residual restenosis ≤30% with no major complications) was achieved in 99% of cases in CBA group and 100% in cases of BA group. Follow-up angiography was performed in all patients at (5.8?1.6) months. The diameter stenosis percent after CBA was lower and the instant gain after CBA was larger than that after BA (11.81%?9.17% versus 26.33%?10.04% and 1.96?0.51 mm versus 1.51? 0.54 mm, respectively; P

Seventy-one patients with variant angina (VA) admitted in the Cardiology Department from January 2003 to March 2011,were divided into non-stenosis group (stenosis < 50%,n =43) and stenosis group (stenosis ≥50%,n =28) according to the degree of stenosis.The differences of the risk factors,clinical manifestations,electrocardiogram,echocardiogram and laboratory examinations between these two groups were compared.The average age of patients in stenosis group 58 ± 8 y was higher than that in non-stenosis group (52 ± 9 y,t =2.43,P =0.02).Other risk factors,including male gender,smoking,hypertension,diabetes mellitus and lipid disorder did not show any differences between the two groups.Percentage of patients with angina pectoris lasting less than 5 min was higher in stenosis group (x2 =5.98,P =0.02),while percentage of effort angina,seeking medical consultation ≤ 6 months of onset and hemodynamic disorders showed no difference.Laboratory examinations had no differences.It is difficult to determine whether the VA patient has fixed coronary stenosis by analyzing the risk factors,clinical manifestations and laboratory examinations; to determine the fixed coronary stenosis coronary angiography is necessary.

Blue laser imaging (BLI) is a new endoscopic system equipped with the laser beam emitting two different wavelengths.It produces bright and high resolution images for observation of microvascular and microsurface patterns of esophageal and gastric mucosa, helping the diagnosis of early upper gastrointestinal cancer.Compared with the existed endoscopic techniques, BLI shows its unique advantages.In this article, advances in application of BLI in diagnosis of early upper gastrointestinal cancer were reviewed.

Objective: To observe the changes of circulating fractalkine and its receptor CX3CR1 level in patients with chronic congestive heart failure (CHF).
Methods: Our work included 2 group, CHF group, n=55 patients and Control group, n=25 healthy subjects. Plasma level of soluble fractalkine (sFKN) was measured by ELISA, CX3CR1 in peripheral blood mononuclear cell was examined by lfow cytometry method. The relationship between sFKN and NT-proBNP was studied.
Results: Compared with Control group, CHF group had increased sFKN level, P=0.004, and the patients with NYHY III, IV were more than NYHY II, and CHF group also had the higher CX3CR1 expression (14.7 ± 8.1), P<0.05. The CX3CR1 level increased accordingly with NYHY classiifcation, as the patients with NYHY II, CX3CR1 was at (25.1 ± 12.4), P=0.03 compare with Control group;with NYHY III, CX3CR1 was at (37.3 ± 11.0) , P=0.04 compared with NYHY II;with NYHY IV, CX3CR1 was at (41.7 ± 11.1), P=0.009 compared with NYHY II. The circulating sFKN level was positively related to pro-BNP level (r=0.364, P<0.01).
Conclusion: The circulating FKN l and its receptor CX3CR1 might be involved in pathogenesis of immune-inlfammatory pathogenesis in CHF patients.
