Objective To investigate the effect of cardiac resynchronization therapy on improving heart function and reversing left ventricular remodeling in chronic heart failure patients. Methods Eleven patients with NYHA class Ⅲ to Ⅳ heart failure, ejection fraction ≤35% and QRS duration ≥130 ms were implanted synchronous biventricular pacemaker. Serial assessment was performed before and up to 1-36 months after pacing. Results There were significant improvement of LVEF、 LVFS; and decrease in MR、 LVED and QRS duration. The NYHA class of heart function was improved from Ⅲ-Ⅳ to Ⅰ-Ⅱ. Six-minute hall walk distances were also improved. Conclusion For patients with NYHA class Ⅲ to Ⅳ heart failure and ventricular conduction delay, cardiac resynchronization therapy could reverse left ventricular remodeling and improve heart function.

Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.Methods Abdominal aorta and inferior vena cava shunting was produced in rats. Pulmonary artery meanpressure (PAMP) of each rat was measured by using a right cardiac catheterization.Pulmonary artery collagen Ⅰ and Ⅲ were detected using immunohistochemisty.Results After 11 weeks of shunting the Qp/Qs was 3.3∶1.0,indicating a large shunt. Pulmonary artery mean pressure was increased as compared with controls[(23.0?0.9) mm Hg vs (15.7? 1.1) mm Hg,P

OBJECTIVETo observe the effect of Hydroxy Safflower Yellow A (HSYA) on the expression of osteogenic markers, such as alkaline phosphatase, Cbf(alpha)l and type I collagen, and explore the mechanism of HSYA in the prevention and treatment of glucocorticoid-induced ischemic necrosis of femoral head.

METHODSFifteen healthy and adult New Zealand white rabbits were collected and weighted 0.9 to 1.3 kg. The rabbits were injected abdominally with anesthetic drugs, then received marrow cavity puncture of tibia and anterior superior iliac spine to get bone marrow blood. Rabbits bone marrow mesenchymal stem cells (BMSCs) were separated from the bone marrow blood, cultured in vitro and passaged. The 3rd generation of BMSCs which had good growth condition were randomly divided into blank group, model group and HSYA groups with different doses. The BMSCs in model group were treated with high dose of dexamethasone to induce adipogenic differentiation of cells cultured in vitro, and inhibit osteogenic differentiation. The BMSCs in HSYA groups received high dose of dexamethasone and different concentrations of HSYA simultaneously. The blank group received not any special handling. After a week,the expressions of alkaline phosphatase, Cbf(alpha)l and type I collagen mRNA were detected.

RESULTSThe alkaline phosphatase activity was significantly decreased in BMSCs of the model group as compared with the blank group (P < 0.01), and the expression of Cbf(alpha)l and type I collagen mRNA were also decreased significantly (P<0.01). The alkaline phosphatase activity was significantly increased in BMSCs of each HSYA group as compared with the model group (P < 0.05 or P < 0.01), and the expression of Cbf(alpha)l and type I collagen mRNA were also increased significantly (P < 0.05 or P < 0.01).

CONCLUSIONThe mechanism of HSYA may be related to the effect of antagonism to the reduced osteogenic differentiation induced by glucocorticoid.

Objective To compare the surgical effects of transurethal enucleation of prostate (TUEP)with transurethal resection of prostate (TURP) by a retrospective analysis of clinical data.Methods The patients in this study were divided into the groups of TUEP (enrolled in 2010 and 2011,n =77) and TURP (enrolled in 2009,n =27) with prostate larger than 60 g and smaller than 60 g respectively.Comparisons were made between the two groups in operation time,blood loss volume and weight of resected prostate.Results In the group of patients with prostate larger than 60 g,there was no significant difference in prostate weight ((88.5 ± 9.2) g vs.(107.0 ± 15.30) g,P =0.255),operation time ((91.5 ± 8.8) min vs.(118.3 ± 20.2)min,P =0.083),and weight of resected prostate ((48.0 ± 4.6) g vs.(58.4 ± 5.4) g,P =0.32) between the TUEP (53 patients) and the TURP (12 patients) groups.There was significant difference in blood loss ((110.0 ± 16.4) ml vs.(193.3 ± 22.3) ml,P =0.011) between the two groups.In the group of patients with prostate smaller than 60 g,there was no significant difference in prostate weight ((43.1 ± 3.2) g vs.(36.8 ± 3.4) g,P =0.072),operation time ((62.7 ±6.8) min vs.(69.3 ±6.2) min,P =0.431),blood loss ((56 ± 5) ml vs.(110±20) ml,P=0.082),and weight of resected prostate ((26.3 ±2.4) g vs.(23.6 ±2.1) g,P =0.291) between the TUEP (24 patients) and the TURP (15 patients) groups.Conclusion Compared with TURP,TUEP has the advantages of less blood loss in the treatment of patients with prostate larger than 60 g.With the improvement of surgeon' s experience and development of operation techniques,TURP will be replaced by TUEP.In the treatment of patients with prostate smaller than 60 g,the operation modality can be chosen by the surgeon based on his experience and proficiency.
