[Objective]To review the treating effect of cases of the developmental dysplasia of the hip in old age children by a one-stage combined Pemberton operation and femoral shortening and investgate if the hip joint stiffness rate and ischemic necrosis rate of femoral head after operation are reduced. [Method]From June 2002 to Decempber 2006, 136 hip congenital dislocation of 101 old age children (7 years to 14 years) were treated by Pemberton operation and femoral shortening,and were followed-up from 1.5 years to 4 years(average, 2 years and 7 months).[Result]Thirty-one cases can only bend their hip joint below 90 degrees, accounting for 22.79% of all. Thirty-eight ischemic necrosis of femoral head occurred which accounted for 27.94%.The rate of ischemic necrosis of the femoral head and hip joint stiffness of old age children after operation were reduced obviously according to the standard by Salter.[Conclusion]Pemberton operation and femoral shortening are preferred in treating the developmental dysplasia of the hip of old age children.It can reduce the rate of ischemic necrosis of femoral head and hip joint stiffness.

Objective To investigate the mouse liver blood vessel images using phase contrast X-ray imaging with synchrotron radiation. Methods 6 female C57BL/6 mice were randomly divided into two groups, 3 mice in each group. In one group, livers excised after hgated arteries, veins and common bile duct. In another group, iodine infused via the portal vein and drained from inferior vena cave until all the blood in the portal veins and hepatic veins was displaced. After infusion, arteries, veins and common bile duct were ligated and livers were excised. Results Blood vessel images were clearly produced by diffraction enhanced imaging. This method can discriminate vessels down to about 40 μm in diameter without contrast agent. Using a contrasting agent more details could be produced. In one liver lobe, the entire branch of the portal vein could be clearly produced by one by one phase contrast image from the main axial blood vessels of liver lobe to the nine generation of branching. Conclusions Phase contrast imaging has the advantage of good contrast and high spatial resolution.

Objective · To evaluate the surgical outcome of RPR composite technique for complex hypertrophic obstructive cardiomyopathy (HOCM). Methods · From June 2009 to December 2015, 9 complex HOCM patients received RPR procedure. There were 6 males and 3 females with age from 22 to 63 years old and the average age of (43±19) years old. Transthorax echocardiography (TTE) showed systolic anterior motion (SAM) and at least moderate mitral valve regurgitation (MR) in all patients before operations. Transesophageal echocardiography (TEE) was used to evaluate the results of procedures during operation. All the patients had been followed up since one week after operation and examined by TTE. Results · All the patients were discharged without complications. Intraoperative TEE indicated that left ventricular outflow tract pressure gradient (LVOTPG) significantly decreased from (92±14) mmHg before operation to (9±3) mmHg after operation (P<0.01). SAM in all the patients disappeared. One week after operation, TTE demonstrated remarkable reduction in the thickness of ventricular septum, LVOTPG and MR than those before operation (P<0.01). Mean follow-up was 26 months. All the patients became asymptomatic. LVOTPG remained low and MR remained mild. There were no deaths, reoperations, or any other adverse consequences. Conclusion · RPR technique is an effective surgical method to relieve LVOTO and MR of complex HOCM to lead a better life.

Objective To investigate the anti-inflammatory effect of C1q/ tumor necrosis factor (TNF)-related protein 9 (CTRP9) in RAW264.7 mouse macrophage cells treated with oxidized low density lipoprotein (oxLDL),and to explore its mechanism.Methods RAW264.7 mouse macrophage cells were divided into three groups:the control group,the oxLDL group (treated with oxLDl) and the gCTRP9-oxLDL group (pretreated with recombinant globular domain of CTRP9 and stimulated by oxLDL).Foam cells were detected by oil red O staining.Western blot was used to detect the expressions of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α) and monocyte chemoattractant protein 1 (MCP-1).In addition,the expression levels of NF-κB p65 in cytoplasm and nucleus proteins extraction were both determined.Results The relative levels of MCP-1 and NF-κB were increased in the oxLDL group as compared with the control group (1.66±0.09 vs.1.03±0.10,0.52±0.11 vs.1.03±0.06,both P＜0.05).The expression levels of TNF-α and MCP-1 were decreased in gCTRP9+oxLDL group as compared with the oxLDL group (both P＜0.05).The expression level of NF κB p65 in nucleus 2 and 8 h after treatment was lower in the gCTRP9+oxLDL group than in the oxLDL group (1.03±0.06 vs.0.17±0.10,0.31±0.03,both P＜0.05).Conclusions oxLDL may induce the expressions of inflammatory cytokines of TNF α and MCP-1 in macrophage ceils.gCTRP9 pretreatment could reduce the oxLDL-induced pro inflammatory effect and nuclear factor κB translocation may be involved in this process,which suggests that gCTRP9 may play a protective role in anti inflammatory and anti-atherosclerosis.
