Objective Dilated cardiomyopathy (DCM) is generally considered to be accompanied by both left and right ventricular dysfunction,but most studies only analyze the left ventricular function. In this study, we evaluated the effect of arotinolol on right ventricular function in patients with DCM. Methods Right ventricular ejection fraction (RVEF) and right ventricular diameter (RVD) were measured by two-dimensional echocardiography (2-DE) in 33 DCM patients; RVEF measured by first-pass radionuclide angiography (FPRA) was compared with that by 2-DE. Results The treatment with arotinolol for one year resulted in a reduction in the right ventricular diameter (baseline, 23.0 ± 8.3 mm vs after one-year treatment, 20.7 ± 5.4 mm; P=0.004 ) and an associated increase in ejection fraction (baseline, 36.9 ± 10.3% vs after one-year treatment, 45.8 ± 9.6%; P < 0.001 ); there is a high correlation between the 2-DE method and radionuclide ventriculographic method. The correlation coefficient is 0.933 (P<0.001). Conclusion Arotinolol therapy could not only improve left ventricular function, but also improve right ventricular function in DCM patients.

Objective:To investigate the effect of low molecular weight heparin (LMWH) on the inflammatory response of PC12 cells induced by oxygen glucose deprivation (OGD) and its related mechanism.Methods:The PC12 cells were cultured in vitro were randomly divided into sham(control) group, OGD group, LMWH group and blocking agent group. The latter group was divided into six groups: Eritoran+ OGD group, LMWH+ Eritoran+ OGD group, ST2825+ OGD group, LMWH+ ST2825+ OGD group, pyrrolidinedithiocarbamate (PDTC)+ OGD group and LMWH+ PDTC+ OGD group. OGD cell model was established. Cell counting kit-8 (CCK-8) assay was used to detect cell activity. The expressions of toll-like receptor 4 (TLR4), MyD88 and nuclear factor κB (NF-κB) mRNA and protein were detected by real time polymerase chain reaction (qRT-PCR) and Western blot. The concentration of interleukin (IL)-1β, IL-6, tumor necrosis factor-α(TNF-α) and S100β were determined by enzyme linked immunosorbent assay (ELISA). Results:The cell activity of OGD group was significantly lower than that of control group on the first, second, third day ( P<0.05). Compared with OGD group, the activity of LMWH group was increased on the second, third day ( P<0.05), but lower than that of control group ( P<0.01). The mRNA expression of TLR4, MyD88 and NF-κB was significantly increased in OGD group compared with the control group ( F=144.9, F=710.5, 79.51, P<0.01). Compared with OGD group, the mRNA expression of TLR4, MyD88 and NF-κB were significantly decreased after treatment with LMWH ( P<0.01), and the specific inhibitor of TLR4, MyD88 and NF-κB enhanced the anti-inflammatory effect of LMWH. The protein expression of this pathway was consistent with that of the gene. The concentration of IL-1β, IL-6, TNF-α and S100β in OGD group was significantly higher than control group ( P<0.05). After treatment with LMWH, the concentrations of inflammatory factors and S100β were significantly decreased compared with OGD group ( P<0.01). When hinder TLR4, MyD88 and NF-κB respectively by Eritoran, ST2825 and PDTC, the concentrations of inflammatory factors and S100β were significantly decreased, but it was still higher than control group ( P<0.05). Conclusions:OGD can cause pathological damage of PC12 cells, including high expression level of S100β and aggravation of inflammatory reaction. LMWH can improve cell activity, down-regulate inflammatory reaction degree and protect the cells. Using inhibitors of TLR4/MyD88/NF-κB pathway to inhibit the corresponding target, the up-regulation of inflammatory factors by OGD can be inhibited in varying degrees. These suggested that LMWH may regulate inflammatory reaction of PC12 cells induced by OGD through TLR4/MyD88/NF-κB pathway.

BACKGROUND:After the internal fixation of cannulated screws in femoral neck fractures,because the affected limb is often unable to bear weight in the short term and the implants with high stiffness have a stress shielding effect on the fracture end,it is easy to cause osteoporosis of the affected limb and changes in the biomechanical distribution of the proximal femur,the incidence of osteonecrosis of the femoral head is high after surgery.At present,few studies have been conducted on the biomechanical effects of osteoporosis at the proximal end of the femur occurring after femoral neck fracture surgery on femoral neck fracture treated with cannulated screws. OBJECTIVE:Using finite element analysis,to investigate the biomechanical effects of osteoporosis occurring after femoral neck fracture surgery on femoral neck fracture treated with cannulated screws and explore the role of biomechanical factors in osteonecrosis of the femoral head. METHODS:Based on the obtained CT scan data of the femur in a patient with a femoral neck fracture,a proximal femoral model for internal fixation for femoral neck fracture was established by Mimics 19.0,3-Matic,UG 11.0,Hypermesh 14.0,and Abaqus software.One finite element model of the proximal femur without osteoporosis and three finite element models of the proximal femur with osteoporosis were analyzed using Abaqus software.The stress,contact pressure,displacement peak and cloud map under different components of the four models were measured and analyzed,and the internal stress changes and distribution of the femoral head were compared and analyzed. RESULTS AND CONCLUSION:The stresses and contact pressures of the femoral head and lower anterior cannulated screws varied more with the degree of osteoporosis.The peak displacement of the four models increased slowly with the degree of osteoporosis.By one-way analysis of variance,there was no significant effect of the degree of osteoporosis on the peak stress,contact pressure,and displacement of the different components.The internal stress distribution of the femoral head changed with the degree of osteoporosis.Changes in the biomechanical environment of the proximal femur have an important impact on osteonecrosis of the femoral head.
