Objective To evaluate the effect of trimetazidine in ischemic cardiomyopathy patients with impaired systolic function. Methods There were 90 cases in total, and were divided into two groups randomly: 42patients took conventional therapy,and 48 patients took trimetazidine additionally. Plasma levels of brain natriuretic peptide (BNP), left ventricular ejection fraction(LVEF) and left ventricular end-diastolic dimension(LVEDD) were measured before and after trimetazidine therapy at 6 months, 12 months. Results Compared to conventional therapy group, LVEF, LVEDD and BNP were significantly improved in the trimetazidine group (P ＜ 0.01 ). Conclusions Trimetazidine additional to conventional therapy might improve heart function and reverse ventricles reconstitution in ischemic cardiomyopathy patients with impaired systolic function.

Objective To study the effect of angiotensin II in its different concentrations and different action time on VEC apoptosis and the expression of Fas, Bcl-2 in vascular endothelial cells (VEC) and to study the influences of enoxaparin on the above roles. Methods Flow cytometer was used to measure the apoptosis ratio and the expression of Fas, Bcl-2 which were induced by angiotensin II in its different concentrations and different action time, and influenced by enoxaparin. Results Apoptosis ratio(1.86?0.18,30.62?4.20;1.67?0.15,30.08?4.41)and the expression of Fas(1.13?0.16,14.85?1.47;1.13?0.16,15.67?1.97), Bcl-2 (2.38?0.43,9.62?1.81;2.38?0.43,12.33?1.73)were induced and increased by angiotensin II with the increase of concentrations and action time. Enoxaparin had an effect on apoptosis ratio and the expression of Fas, Bcl-2, which were induced by angiotensin II(30.62?4.20,18.31?2.64;14.85?1.47,7.28?1.36;9.62?1.81,16.05?1.79). Conclusions Apoptosis ratio and the expression of Fas, Bcl-2 may be induced and increased by angiotensin II with the increase of the concentrations and the action time. Enoxaparin may have the reduce effect on apoptosis ratio and the expression of Fas and Bcl-2 in vascular endothelial cells.

Objective To observe the effects of metformin on the serum levels of adiponectin,interleukin-18(IL-18) and C-reactive protein(C-RP) in overweight/obese type 2 diabetes. Methods The changes of serum levels of HOMA2-IR,adiponectin,IL-18,C-RP and lipid profiles were observed before and after the treatment of metformin. Results After the eight weeks of treatment,the levels of adiponectin and IL-18 were not significantly changed,while C-RP(0.49±0.23 vs 0.89±0.22ng/dl),total cholesterol(TC)(4.58±0.83 vs 6.15±2.23mmol/L),LDL-C(2.65±0.78 vs 3.66±0.84mmol/L) and HOMA2-IR(1.1±0.7 vs 2.3±1.7) were decreased (all P<0.05),HDL-C(1.23±0.30 vs 1.02±0.24mmol/L) was increased (P<0.05). Conclusions Metformin may reduce the serum C-RP level and modulate the disorder of blood lipids,but may have no effect on adiponectin and IL-18

The properties of polyethyleneimine-cholesterol cationic lipopolymer (PEI-Chol) as gene carries and its gene transfer efficiency in vitro with lipid microbubbles were presented in this paper. PEI-Chol lipopolymer was synthesized by linking cholesterol chloroformate to the amino groups of branched poly(ethyleneimine) (PEI) of 1 800. The structure and molecular weight of PEI-Chol were confirmed by IR, 1H NMR and MADI-TOF-MS (matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry), respectively. The average molecular weight of PEI-Chol was approximately 2 000. The gene delivery system of bubble/PEI-Chol/DNA was constructed by mixed PEI-Chol/pDNA (N/P 10:1) complexes with lipid microbubbles (2-8 microm) which were prepared by DPPC, DSPE-PEG2000 and perfluoropropane with the reverse phase evaporation technique. pEGFP-Cl (enhanced green fluorescent protein) was used as report gene to investigate the DNA condensing ability of PEI-Chol lipopolymer by agarose gel electrophoresis. And their cytotoxicity and in vitro transfer efficiency of different complexes were compared with each other in A549 and MCF-7. The results indicated PEI-Chol lipopolymer can condense plasmid DNA when N/P ratio upto 4, PEI-Chol complexes and bubble/PEI-Chol/DNA complexes were nontoxic to A549 and MCF-7 when formulated at the N/P ratio of 10/1 as determined by MTT assay. This bubble/PEI-Chol/DNA delivery system provided good transfer efficiency with other desirable characteristics such as against-precipitation of plasma proteins. In conclusion, bubble/PEI-Chol/DNA complex is a novel non-viral gene delivery system.

To explore the velocity difference between specifications and categories of liquid with the same pressure infusion bag in order to widen the specification range of the liquid for pressure infusion. Pressure infu-sion experiments were performed with three specifications of normal saline of 100, 250 and 500 ml to compare the veloci-ties of different specifications of liquid, and with 500 ml normal saline, (5%, 10% and 50%) glucose injection, 5% glu-cose and sodium chloride injection, 5% sodium bicarbonate injection, 10% fructose injection, 706 plasma substitute, 20%mannitol injection and etc to make clear the velocities of different categories of liquid. With the same pressure, there were no significant differences between the velocities of three specifications of liquid, and between those of cate-gories of liquid with the same specification and concentration; the difference was significant between the same category of liquid with different concentrations, and the velocity showed a negative correlation with the concentration. The pressure infusion bag is compatible with 100, 250 and 500 ml liquid, and the velocity may be constant in case some specification of liquid is replaced by another one. The velocity has to be regulated in case the concentration or category of the liquid changes, when the pressure infusion is performed.
