Aim To study the mechanisms of the pro-tective effect of procyanidin B2 ( PCB2 ) on the myocar-dial cell apoptosis induced by lipopolysaccharide ( LPS) . Methods Using the primary culture rat myo-cardial cells, myocardial cell injury model was induced by LPS. PCB2 low, medium and high dose groups, were cultured with 6. 25 , 12. 5 , 25. 0 μmol · L-1 PCB2 respectively in DMEM medium for 24 h continu-ously. Myocardial cell survival rate was determined by MTT colorimetric method. Cardiacmyocyte NOX activi-ty was determined by lucigen chemiluminescence meth-od . Western blot analysis was used to detect myocardi-al NADPH oxidase p47phox expression. TUNEL method was used to detect apoptosis and flow cytometry was used to determine the content of myocardial cells ROS. Results Compared with control group, the cell dam-age induced by LPS group myocardial cell survival rate significantly decreased ( P <0. 01 ) , and myocardial cell NOX activity, p47phox expression, apoptotic cell number and ROS content were significantly increased (P<0. 01). PCB2 low, medium and high dose groups cell survival rates were significantly elevated, myocar-dial cell NOX activity and p47phox expression, apoptotic cell number and the ROS content decreased significant-ly in a dose-dependent manner ( P <0. 01 ) . Conclu-sion PCB2 protects myocardial cell apoptosis induced by LPS via inhibiting the expression of NADPH oxidase activation, p47phox expression and reactive oxygen spe-cies generation.

Aim To explore the protective effects of LPPC ( procyanidins extracted from the litchi pericarp) on cardiomyocyte apoptosis in septic rats and its mech-anisms. Methods The rats were randomly divided in-to 5 groups, and were given orally the drug for two weeks continuously. The control group ( control) and sepsis model group ( LPS ) were given distilled water once a day. LPPC low, medium and high dose groups were given LPPC 50 , 100 , 200 mg · kg-1 · d-1 re-spectively which were prepared freshly every day. After the treatment, sepsis animal models were established. Except for the control group, other groups were injec-ted LPS (lipopolysacchride, 10mg·kg-1) intraperito-neally to induce acute sepsis model. 4hrs later, rat se-rum was collected, isoenzyme ( CK-MB ) , lactate de-hydrogenase ( LDH ) and activity of aspertate amin-otransferase ( AST/GOT) were detected. Then rat car-diac tissue was obtained and cardiac tissue malondial-dehyde ( MDA ) , total antioxidant capacity ( T-AOC ) and reduced glutathione ( GSH ) content were deter-mined. TUNEL staining was performed to analyze the apoptosis of myocardial cells. Cleaved caspase-3 and TNF alpha protein expressions were analyzed by West-ern blot. Results Compared with the control group ( control) , serum of sepsis model group rats CK-MB, LDH, AST/GOT and cardiac tissue MDA content were significantly increased (P<0. 01). At the same time, the activity of cardiac tissue T-AOC and GSH de-creased obviously ( P<0. 01 ) . The apoptotic myocar-dial cells increased significantly ( P<0. 01 ) , and the expression level of cleaved caspase-3 and TNF alpha decreased obviously ( P <0. 01 ) . LPPC pretreatment significantly decreased the serum CK-MB, LDH, AST/GOT and tissue MDA content, increased tissue T AOC and GSH activity, attenuated apoptosis of rat myocardi-al cells significantly, and decreased expression level of cleaved caspase-3 and TNF alpha. Conclusion LPPC pretreatment can significantly attenuate rat myocardial cell apoptosis induced by sepsis, and the underlying mechanisms may be related to its anti-oxidative effects.

OBJECTIVETo assess the feasibility and safety of using the modified active fixation pacing leads model to pace the right ventricular outflow tract septum.

METHODSA total of 136 patients undergoing artificial heart pacemaker implantation with active fixation pacing leads were randomized into two groups to receive conventional right ventricular outflow tract pacing (CRVOTP) or modified right ventricular outflow tract pacing (MRVOTP). The electrode lead wire core was modeled in a double-curved three-dimensional shape in CRVOTP group and in a J-shaped bend in MRVOTP group before fixation at the right ventricular outflow tract septum.

RESULTSRight ventricular outflow tract septum pacing was achieved successfully in all the patients. None of patients experienced serious complications. No significant differences were found between the two groups in the number of times of electrode fixation, pacing thresholds, impedance, R wave height or QRS wave width during the operation, but MRVOTP was associated with a reduced time of X -ray exposure and operation (P<0.05) due to the convenience in electrode modeling and in passing the leads through the tricuspid annulus and the direct access to the right ventricular outflow tract septum. Postoperative follow-up of the patients showed no incidence of active fixation pacing lead dislocation and comparable pacing thresholds of the ventricular electrodes, impedance, R wave height and QRS wave width between the two groups.

CONCLUTIONSUsing the modified active fixation pacing leads model to pace the right ventricular outflow tract septum can reduce the time of X -ray exposure and operation with a low probability of lead damage.
