Objective To compare the biomechanical properties between the two-level fixation by im- plantation of pedicle-screws into the adjacent upper and lower vertebrae of the fractured vertebra and the three-level fixation by implantation of pedicle screws into the fractured vertebra and its adjacent upper and lower vertebrae in the treatment of thoracolumbar burst fractures.Methods Eight fresh frozen calf spines were used in this study.Each specimen was tested in four models:intact model as the control,L1 burst fracture model,two-level fixation model, and three-level fixation model.The L1 burst fracture model was created on a biaxial material testing machine (MTS858 Bionix test system,America).During the experiment,the flexion,extension,bilateral bending and axial rotation loadings were applied to the specimens and the range of motion(ROM)was measured with a three-dimensional laser analysis apparatus and the stiffness was calculated subsequently.One-way statistical analysis was used.Results The ROMs under six different loadings in the fracture model became larger obviously(P＜0.05)and the stiffness decreased(P＜0.05).The ROMs in both fixation models were smaller than those in the other models(P＜0.01)and the stiffness increased distinctly(P＜0.05).There were no significant differences in ROMs and stiffness between the two-level fixation and three-level fixation models(P＞0.05).Conclusion Two-level fixation provides similar biomechanical stability as three-level fixation does in the reconstruction of unstable thoracolumbar fractures.

Objective To study the the feasibility of real-time 3D transesophageal echocardiography (RT-3D TEE) to measure the distance between the coronary ostial and the junction of left ventricle and artery.Methods The RT-3D TEE image of the aortic root was collected intraoperative in 65 cases who were refered to our center for valve replacement.The reconstruction of the aortic annulus was done in the QLAB quantitative analysis software and the height parameter of the annulus could be generated.Meanwhile the coronary artery position was observed and the distance between the coronary ostial and the junction of left ventricle and artery was measured respectively.Results In the 65 cases,49 cases clearly showed bilateral coronary ostial,three cases only showed the left coronary ostial,six cases only showed the right coronary ostial,seven cases of both sides of the coronary ostial were unclear.The shows rate of right coronary ostial was 84.61％ (55/65),with the left coronary ostial 81.54％ (52/65).The measured value of the L-AA in systole and diastole were (15.5 ± 1.9)mm,(12.8 ± 1.5)mm,the R-AA systole and diastole measured values were (13.7 ± 1.8)mm,(12.4 ± 1.7)mm,respectively,there was significant difference between systole and diastole respectively.The aortic annulus height (H) got by 3D reconstruction of the aortic annulus was lower than ventricular-arterial junction to the coronary artery distance in both systole and diastole.Conclusions Not only can RT-3D TEE reconstruct the annulus,but also can show and measure the distance between the coronary ostial and the junction of left ventricle and artery respectively.

Methods Enzyme-linked immunosorbent assay was used to measure th e fasting serum TNF-? levels of 42 women with GDM (28～39 gestational weeks), a n d 40 cases of normal pregnant women in the third trimester. Fasting plasma gluc ose, insulin, C-peptide and glycosylated hemoglobin (HbA1c) were also measured at the same time. Insulin sensitive index (ISI) was calculated. Res u lts (1)Significantly elevated serum TNF-? was found in the women w i th GDM(5.2?1.6) ng/L as compared with the healthy pregnant women in third t rimester (4.5?0.5)ng/L(P

Objective:To explore the role of peripheral blood monocyte subsets in the pathogenesis of rheumatoid arthritis (RA),we therefore decided to compare the percentage of monocyte subpopulations in peripheral blood,as well as cytokines secretion function,to that of healthy controls. Methods:22 patients with RA and 22 cases of healthy controls ( HC) were drew 3 ml fresh venous blood into a tube containing heparin. The percentage of monocyte subsets,expression of Toll-like receptor(TLR)2,HLA-DR,triggering receptor expressed on myeloid cells-1(TREM-1) on intermediate monocyte and mean fluorescence intensity(MFI) of intracellular tumor necrosis factor-α ( TNF-α) were evaluated with the methods of flow cytometry ( FCM ) . The correlation between percentage of monocyte subsets and serum cytokines was explored. Statistical significance between parametric data was determined by the students't-test. Results:Compared to HC controls, the percentages of intermediate monocytes were significant higher in RA patients [ ( 11. 7 ± 1. 6)% vs (4. 6±1. 2)%,P<0. 05],as well as the expression(MFI) of TLR2 (750. 2±110. 3 vs 526. 8±98. 6) and TREM-1 (58. 4± 12. 1 vs 40. 3±10. 2) on intermediate monocytes (P<0. 05). The expression of HLA-DR on intermediate monocytes of RA patients had no difference with HC controls (P>0. 05),while MFI of intracellular TNF-αin intermediate monocytes of RA patients were significant higher than that of HC controls (46. 3±6. 4 vs 36. 7±8. 3,P<0. 05). In addition,RA patients showed a positive correlation between the percentage of CD14highCD16+ monocytes and DAS28 scores(r=0. 538,P=0. 009),as well as the serum levels of TNF-α,IL-17 ( r=0. 471,P=0. 027;r=0. 593,P=0. 003). Conclusion:Monocyte subpopulations from RA patients are abnormally skewed toward to in-termediate monocytes which has high expression of TLR2 , TREM-1 and the function of TNF-α secretion. Therefore, intermediate monocytes may play a role in the pathophysiology of RA. By modulating polarization or blocking monocyte cell surface receptors could be a new treatment of RA.

Objective To determine the value of the apparent diffusion coefficient (ADC) of magnetic resonance diffusion-weighted imaging (MRDWI) combined with squamous cell carcinoma antigen (SCC) and carcinoembryonic antigen (CEA) in the evaluation of the efficacy and prognosis of concurrent chemoradiotherapy for cervical carcinoma.Methods A total of 80 patients with cervical squamous cell carcinoma confirmed by histology or cytology in our hospital from 2013 to 2016 were included in this study.Of the 80 patients, 39 were FIGO stage ⅡB, 7 were stage ⅢA, 26 were stage ⅢB, and 8 were stage ⅠVA.MRDWI examination and SCC and CEA measurements were first performed for the patients following group assignment, and the patients were then given extrapelvic radiotherapy (45-50 Gy)+platinum-based chemotherapy plus brachytherapy (20-25 Gy) based on their conditions.MRDWI, SCC, and CEA examinations were performed again after treatment to determine the changes in ADC, SCC, and CEA.In addition, ADC, SCC, and CEA were examined in the middle stage of treatment for 40 patients.Data were analyzed using the paired t-test or ANOVA.Results The overall response rate of the 80 patients after concurrent chemoradiotherapy was 100%.No disease progression was identified in any of the patients until the end of treatment, and the overall survival time of the patients was all above 6 months.Serum SCC and CEA were reduced after treatment (P=0.000,0.000), whereas the ADC value was increased after treatment (P=0.000).The increase in ACD following the decreases in SCC and CEA after treatment (P=0.000, 0.000) was indicative of increased efficacy of the concurrent chemotherapy and radiotherapy.Conclusions MRDWI combined with SCC and CEA is highly reliable for the evaluation of efficacy and prognosis of concurrent chemoradiotherapy for cervical cancer.
