Objective: To explore the correlation among overweight, obesity and markers of prethrombotic state in patients with coronary heart disease (CHD). Methods: A total of 288 patients to hospital from 2013 to 2014 and diagnosed as CHD by coronary angiography were selected. According to body mass index (BMI), they were divided into CHD control group (n=106), overweight group (n=121) and obesity group (n=61). Levels of fibrinogen (Fg), plasma D dimmer (D-D), von Willebrand factor (vWF), antithrombin Ⅲ (AT-Ⅲ) and plasminogen activator inhibitor (PAI)-1 were compared among three groups, then received correlation analysis.Results: Compared with CHD control group, there were significant rise in levels of triglyceride, total cholesterol, fasting blood glucose and mean arterial pressure, morbidity rates of hypertension and diabetes mellitus in overweight group and obesity group, P<0.05 or <0.01. Compared with CHD control group, there were significant rise in levels of Fg [(2.89±0.60) g/L vs. (3.54±0.63) g/L vs. (3.92±0.94) g/L], D-D [(282.13±73.15) ng/ml vs. (390.04±73.54) ng/ml vs. (471.92±80.38) ng/ml], vWF [(108.62±24.66)% vs. (138.45±25.96)% vs. (161.20±29.39)%] and PAI-1 [(6.97±1.28) ng/ml vs. (9.60±1.73) ng/ml vs. (12.33±2.16) ng/ml] in overweight group and obesity group, P<0.01 all, and those of obesity group were significantly higher than those of overweight group, P<0.01 or <0.05; AT-Ⅲ level [(89.94±17.99)% vs. (69.89±20.22)%] significantly reduced in obesity group (P<0.05). Pearson correlation analysis indicated that BMI was positively correlated with markers of prethrombotic state [Fg: r=0.536, P<0.001; D-D: r=0.250, P<0.001; vWF: r=0.611, P<0.001;PAI-1: r=0.788,P<0.001). Conclusion: BMI is positively correlated with markers of prothrombotic state in CHD patients.

BACKGROUND: The effect of Chinese traditional medicine 3'-meisoindigo as well as indimbin derivatives on normal immunocytes is less reported while it is used for antitumor.OBJECTIVE: To investigate the effect of 3'-meisoindigo on the proliferation of the splenocytes and thymocytes of C56BL/6 mouse.DESIGN, TIME AND SETTING: The randomized cytopathology observation was performed between August 2007 and January 2008 at Zhujiang Hospital of Southern Medical University, Guangzhou, Guangdong Province, China.MATERIALS: C57BL/6 mice, clean, male, 6-8 weeks old, weighing (20±2) g.METHODS: The thymus gland and the spleen of C57BL/6 mice were ground to get the single-cell suspension and cells were treated by 5, 10, 15, 20 and 25 μ mol/L 3'-meisoindigo,respectively. Cells without any drug treatment were used as blank control and cells treated by concanavalin A were used as positive control.MAIN OUTCOME MEASURES: Proliferation of splenocytes and thymocytes detected using MTT method; IL-12 activity in culture supematant detected using ELISA method; the cell cycle, apoptosis rate, cell death rate and intracellular reactive oxygen species level detected using flow cytometry; the mRNA level of bcl-2 and cdk2 detected using reverse transcription-polymerase chain reaction; the expression rate of Bcl-2, CDK2 and Bax detected using fluorescence microscope.RESULTS: After treating for 24 hours, 15, 20 and 25 μ mol/L 3'-meisoindigo can significantly inhibit the proliferation of thymocytes and splenocytes (P < 0.05) and the inhibition was dose-dependent and time-dependent. Cells resumed proliferation after removing the 3'-meisoindigo, although they had been treated by 25 μ mol/L 3'-meisoindigo for 72 hours. The secretion of IL-12 was markedly reduced in all 3'-meisoindigo groups versus control groups at each time point (P < 0.05). 15 μ mol/L 3'-meisoindigo could decrease the mRNA expression level of apoptosis-related protein bcl-2 and cyclin cdk2 gene, decrease the expression level of BCL-2 protein and CDK protein, increase Bax expression level, decrease Bcl-2/Bax ratio markedly and started apoptosis.15 μ mol/L 3'-meisoindigo arrested cells in the G2/M stage of the thymocytes and splenocytes, and intracellular reactive oxygen species level elevated dose-dependently and time-dependently.CONCLUSION: In certain concentration range, 3'-meisoindigo can reversibly inhibit the proliferation of thymocytes and splenocytes of C57BL/6 mouse and can inhibit IL-12 secretion in parallel, and start apoptosis.

Objective To measure left atrial appendage (LAA)in patients with atrial fibrillation using Flexi Slice imaging by real time 3D transesophageal echocardiography (TEE),and compare with common multiplane TEE.Methods Forty-six patients with atrial fibrillation were performed 2D and real time 3D TEE.Zero degree,45°,90° and 135° plane were acquired by 2D TEE and Flexi Slice remolding. Maximum and minimum values of ostium of left atrial appendage were acquired in the short axis view of LAA by Flexi Slice remolding.Results Compared with 2D TEE,values acquire by Flexi Slice in measurement of LAA ostium showed no significant difference(P >0.05).The depth measurement by Flexi Slicein 45° and 90° plane showed significant difference with 2D TEE (P-values were successively 0.045, 0.002),and in 0 and 135° plane showed no difference.All values measured by 2D TEE and Flexi Slices showed significant correlation.Bland-Altman plot showed that 94.29% of plots were among limits of agreement,which was (-2.5 mm,2.9 mm).The maximum values of LAA ostium values ranged from 30° to 160°,among which 87% (40/46 cases)distributed between 90° and 1 50°,and minimum values ranged from 0°to 160°,among which 85%(39/46 cases)distributed between 0°and 60°.Conclusions Measurement of LAA can be well achieved by Flexi Slice imaging,which showed significant advantage compared with 2D TEE.

Objective To explore the value of echocardiography in percutaneous left atrial appendage (LAA)closure for stroke prevention in patients with nonvalvular atrial fibrillation during procedure and for short-term follow-up.Methods Twenty patients were enrolled to undergo percutaneous LAA closure with the LAmbre device.Rheumatic valvular diseases were excluded by transthoracic echocardiography (TTE) and transesophageal echocardiography(TEE)before the closure procedure.TEE was performed during the procedure for the trans-septal puncture and the release of the closure device.Combined TEE with angiographic measurements,guidance for the optimal device size was provided.The closure effect and procedure-related complications were observed immediately by TEE and also evaluated by TTE at 1-day and 1-month follow-up.Results All patients underwent LAA occlusion successfully.TEE color Doppler evaluation have shown nine patients with complete closure immediately,one with a ≤ 1 mm residual LAA leak,and ten with a 1 -3 mm jet.There were no other complications during the procedure.One day after the closure,small pericardial effusions were observed for three patients while two of the three were free of the pericardial effusion at the 1-month follow-up.During the short-term follow-up,no damage was found at any anatomical structures near LAA due to the closure process,and there was no significant difference of cardiac function before and after the procedure.Conclusions With the guidance of TEE,the successful rate of percutaneous LAA closure procedure was preferable and the occurrence rate of compliance was acceptable. And TTE played an important role in patients'short-term follow-up.

Objective To obtain area strain parametersuse of left ventricle in patients with coronary heart disease (CHD) by three-dimensional speckle tracking imaging(3D-STI),evaluate the systolic function and synchronization of left ventricle depending on different degrees of coronary artery stenosis,and then search new evidence for evaluation and diagnosis of the systolic function of left ventricle.Methods 94 patients were recruited diagonosed as CHD were recruited and their 3D-STI dynamic images were stored 24 hours before coronary angiography.All patients were divided into three groups (the severe stenosis group,the moderate stenosis group,and contrast group) according to the results of coronary angiography.Then the conventional echocardiographic parameters,area strain(AS),area strain dyssynchrony index(ASDI),and the standard deviation of the peak time of AS(AS-SD) were measured.Results There were no significant differences among conventional echocardiographic parameters of the three groups.Compared to the moderate stenosis group and the contrast group,the AS,ASDI and AS-SD of the severe stenosis group were significant different (P ＜0.001),however there were no differences between the moderate stenosis group and the contrast group (P ＞0.05).The ROC curve showed that the diagnostic value was the highest to detect severe stenosis when using ASDI≥1.90％ as the cutoff value,with 84.2％ of the sensibility,and 94.1％ of the specificity.Conclusions The area strain parameters of 3D-STI are effective indice as clinical references to evaluate the systolic function of left ventricle and the degree of coronary artery stenosis,in particular,the ASDI is the most effective parameter.

BACKGROUND: Some reports demonstrated that, autoallergic or hematopoietic stem cells transplantation combined with chemotherapy received good outcomes in treating medulloblastoma, which can prolong survival time of patients. However, whether haploidentical hematopoietic stem cells transplantation can treat medulloblastoma remains poorly understood.OBJECTIVE: To firstly report a patient receiving haploidentical hematopoietic stem cells transplantation for treating medulloblastoma.METHODS: A terminal cancer patient with bone matastases successively received six lymphocyte transfusions from an unrelated donor combined with chemotherapy and three haploidentical hematopoietic stem cell transplantations.RESULTS AND CONCLUSION: The patient presented erythra, accompanied by fever, diarrhea and yellow brown liquid stools, which was considered as graft versus host disease, and treated by urbason, gammaglobulin, CellCept, Prograf, Basiliximab (anti-CD25 antibody), Infliximab (anti-tumor necrosis factor α antibody), effective antibacterial and supportive treatments. After that, the erythra and diarrhea were remised. But the patient died from cerebral hemorrhage. Allogeneic lymphocyte transfusion can kill or damage tumor cells, improve life quality, but the outcome is restrained for patient with a high tumor burden. Immunosuppressant, such as anti-CD25 antibody and anti-tumor necrosis factor α antibody should be timely used in consideration of allogeneic hematopoietic stem cell transplantation.

OBJECTIVETo investigate effects of the variation of immune function in high humidity environment in different time, and lay a foundation for further study of the related mechanism.

METHODThirty SD rats were divided into 3 groups (n = 10): 20 day group, 40 day group in 90% relative humidity chamber and control group in normal relative humidity. Peripheral blood and spleens were collected to detect the levels of T lymphocyte subsets by Flow Cytometery.

RESULTSIn peripheral blood of the 20 day group rats, the CD3+ %, CD4+ %, CD8+ % and CD4+/CD8+ were 52.91 +/- 6.27, 37.80 +/- 4.11, 14.85 +/- 3.73 and 2.72 +/- 0.82 separately. Expect CD3+ %, they all had significant differences (P < 0.05). In addition, the data of the 40 day group rats showed no diversity in statistics. In spleen, CD8+ % of the 20 day group rats was 6.23 +/- 2.87 with significant differences (P < 0.05) and IgG, IgA and IgM did not change a lot in blood serum of the high humidity groups except C3 of the 20 days group (P < 0.05).

CONCLUSIONIn high humidity environment, the immune function of the rats increased in the initial stage. As time went on, the immune function gradually went to normal level through the self adjustment.

Compared with living spray method, it focused on the investigation of different inoculation methods, various inoculation concentration and the influence of different seeding age on soft rot-resistance in Jinxianlian. The results showed that (1) Inoculated with dropping connection, the difference of disease index between A. roxburghii and A. formosanus was grate, so that the disease-resistance could be obviously distinguished. (2) When the inoculation concentration was 1.0 x 10(7) cfu x mL(-1), the difference of disease index was relatively obvious and the disease-resistance could be differentiated well. (3) At the moment of 4-month seeding inoculation, a certain difference of the disease index between A. roxburghii and A. formosanus was existed, so, relatively, it could accurately reflect the resistance difference between various species. With the inoculation of dropping connection, A. roxburghii and A. formosanus of 4-month seeding age was put in the bacteria suspension of inoculation concentration of 1.0 x 10(7) cfu x mL(-1). The identification was taken up after 5 days in the incubator under the condition of 14 h daylight and 28 degrees C. The identification result was conformed with that of the living spray method. To investigate the identification method of in vitro evaluation of soft rot-resistance of Jinxianlian so as to provide the foundation for germplasm utilization and excellent cultivars breeding.
