OBJECTIVE:To investigate the clinical efficacy and safety of alprostadil in the treatment of heart failure in pa-tients with normal left ventricular ejection fraction (LVEF). METHODS:120 patients diagnosed as heart farlture with normal LVEF were divided into observation group and control group by radom number table method,with 60 cases in each group. Control group was given symptomatic treatment;observation group was additionally treated with Alprostadil dried emulsion for injection 10μg,bid,on the basis of control group. Both groups received treatment for 5 d. The cardiac function indexes,serum inflammatory factors and oxidative stress indexes were observed in 2 groups before and after treatment,and the occurrence of ADR was com-pared between 2 groups. RESULTS:Before treatment,there was no statistical significance in cardiac function indexes,serum in-flammatory factors and oxidative stress indexes between 2 groups (P>0.05). After treatment,above indexes of 2 groups were all improved significantly,and the observation group was significantly better than the control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Alprostadil can improve cardiac function of patients with heart failure of normal LVEF,improve serum inflammatory factors and oxidative stress level with good safety.

Objective To investigate the changing of endothelial progenitor cells and nitric oxide in patients with pulmonary arterial hypertension secondary to chronic obstructive pulmonary disease.Method Mononuclear cells from 20 healthy persons (the control group, n = 20) , COPD patients without PAH (COPD non-PAH group, n =30) and patients with PAH secondary to COPD (COPD and PAH group, n=30) were investigated. Total mononuclear cells were isolated from peripheral blood by Ficoll density gradient centrifugation. EPC number and migration were assayed by colony forming unit-EPCs (CFU-EPCs) assay and modified Boyden chamber assay , respectively. EPC adhesion assay was performed by replanting those on fibronectin-coated dishes , then adherent cells were counted. The concentration of NO was measured with method of nitrate reductase.Result The numbers of CFU and migration, adhesion activity of circulating EPCs in COPD[ (21.9±3. 9)CFU-EPC] and PAH group[ (14. 2 ±3. 5)CFU-EPC] were significantly lower than that in non-COPD group and COPD non-PAH group [ ( 24.9 ±4.1) CFU-EPC ]. It was also observed that a strong negative correlation between the levels of PAH and the numbers of CFU and adhesion, migration activity of circulating EPCs. The NO level in the PAH group [ (43. 6 ±4. 8)ng/ml] was significantly lower than that in control group [ ( 67. 17±4.9 ) ng/ml ] ( P < 0.01). The NO level was positively correlated with number and migration ability of EPCs( r =0. 77,0.71, P <0.01) , but not correlated with adhesion ability.Conclusion The number of CFU and migratory, adhesive activity of EPC in patients withPAH secondary to COPD was significantly decreased. These changes may be associated with low level of plasma NO.

BACKGROUND:Bone transplantation is the only method for the repair of bone defects. However, traditional bone transplantation has some disadvantages. Bone tissue engineering, as a new treatment strategy, can achieve the desire therapeutic outcomes. OBJECTIVE:To fabricate a new tissue-engineered scaffold for improving bone repair effectively. METHODS:Hydroxyapatites (HA) with different Ca/P (1.50/1.67) ratios were synthesized by chemical precipitation method and microwave radiation method. Composite scaffolds of palygorskite (APC)/HA/polycaprolactone (PCL)/col agen (COL), APC/calcium deficiency HA (CDHA)/PCL/COL, and APC/PCL/COL (control group) were prepared by solution perfusion-solvent evaporation and ion leaching method. The material characterization, active ingredients, hydrophilic property, and mechanical properties were evaluated by scanning electron microscope, infrared spectrometer, surface contact measuring instrument and universal mechanics, respectively. The histocompatibility of the implant with the host was assessed through animal experiments. RESULTS AND CONCLUSION:By precise control of pH range, HA with different Ca/P ratios could be synthesized. The mechanical properties, air permeability, hydrophilic property of the APC/HA/PCL/COL and APC/CDHA/PCL/COL composite materials were significantly increased compared with the APC/PCL/COL composite material (P<0.05), while the porosity, water absorption expansion rate were significantly decreased (P<0.05). Results from our animal experiments showed that no immune inflammatory reaction was observed suggesting that the composite materials hold good histocompatibility. To conclude, the APC/HA (1.50/1.67)/PCL/COL composite materials are promising bone substitutes in bone tissue repair.
