OBJECTIVETo study clinical efficacy of autologous bone graft for acetabular defect of Crowe III and IV hip dysplasia.

METHODSThe 22 patients with 25 hips of DDH (Crowe type III, IV) from March 2010 to May 2013 were retrospectively analyzed. Total hip arthroplasty (THA) combined autogenous bone grafting was performed for all these patients with osteoarthritis secondary to DDH. Among them, 19 patients were females (21 hips) and 3 patients were males (4 hips), ranging in age from 43 to 67 years old, averaged 55 years old. There were 6 hips with Crowe type III and 19 hips with Crowe type IV. Before surgery, all the patients had hip pain, limb shortening and hip limited function of hip joint. After 12 months, the degree of recovery about limb length, functional recovery, autogenous bone graft fusion were observed.

RESULTSAll the patients were followed up and no dislocation were occurred. At 12 months after operation, the average Harris hip joint llzncation score were 83.30±6.13, and 18 cases got an excellent result and 4 good. The length of lower limbs decreased from preoperative (3.20±0.81) cm to 12 months after operation (0.92±0.23) cm (t=14.864, P<0.05).

Background and purpose:miR-196a2 functions as an oncogene during tumor initiation and pro-gression. The up-regulation promotes tumor cell proliferation, invasion and metastasis. Therefore, it is promising to be an important tumor biomarker. The aim of this study was to investigate whether rs11614913, a gene polymorphic site ofmiR-196a2, is associated with the risk of leukemia.Methods:A case-control analysis was employed. Bone marrow or periph-eral blood was collected from 210 leukemia patients diagnosed from Jan. 2009 to Jul. 2015 in Yantaishan Hospital (case group) as well as 250 healthy people who were physically examined during the same period (control group). Polymerase chain reaction-restriction fragment length polymorphism (PCR-PFLP) was used to detect the genotype of rs11614913. Application test was used to compare the difference in the frequency of each genotype between case group and control group. The odds ratio (OR) of SNP allelic genes was calculated using logistic regression analysis and 95%CI represented the risk of leukemia for each genotype.Results:The distribution differences in the frequency of T/T, C/C, C/T genotype of miR-196a2 rs11614913 between case group and control group were statistically significant (P<0.05). The risk of leukemia for individuals who carried mutant homozygous C/C was 2.661-fold higher than those carried wild-type homozygous T/T, and the difference was statistically significant (P<0.05).Conclusion:ThemiR-196a2 gene polymorphic site rs11614913 was associated with the risk of leukemia. Mutant homozygous C/C or C allelic gene carrying was probably a risk factor for leukemia.

This study aimed to investigate whether β-elemene could improve the dysfunction of vascular endothelial cells induced by low shear force (LSS), and the proliferation and migration of vascular smooth muscle cells induced by oxidized low-density lipoprotein (ox-LDL). Parallel plate flow chambers and ox-LDL were used to establish vascular endothelial cells (ECs) dysfunction model and vascular smooth muscle cell (VSMCs) proliferation and migration model, respectively, and the effects of β-elemene on ECs dysfunction and VSMCs proliferation and migration were examined. The activity of ROS in ECs was measured by DHE and the activity of NO in ECs was tested by DAF-FM DA. The protein phosphorylation of Akt and ERK in ECs were detected by Western blot. The proliferation of VSMCs was measured by MTT. The migration of VSMCs was examined by cell scratch test and Transwell assay. The gene expression of MMP-2 and MMP-9 in VSMCs was measured by RT-qPCR. In ECs, β-elemene could significantly reduce the LSS-induced increase in ROS, significantly increase the LSS-induced decrease in NO, decrease the phosphorylation of ERK, and increase the phosphorylation of Akt. In VSMCs, β-elemene could significantly reduce the proliferation and migration of VSMCs induced by ox-LDL, and reduce the gene expression of MMP-2 and MMP-9. To conclude, β-elemene can improve the LSS-induced ECs dysfunction and ox-LDL-induced VSMCs proliferation and migration.
