High density lipoprotein ( HDL ) has been considered as an important mediator in favoring cardioprotective effects .However , recent studies revealed that HDL-C-raising therapeutics alone failed to reduce the risk of cardiovascular diseases , suggesting that the HDLfunctionalitymay be more critical for its cardioprotective properties than the simple HDL-C levels.microRNAs ( miRNAs) have been identified as the novel regulators of lipid metabolism and played essential roles in the key steps of reverse cholesterol transport, involving in HDL biogenesis , cellular cholesterol mobilization , hepatic HDL uptake and excretion.The intensive research on lipid metabolism-related miRNAs may provide further clarification on the molecular regulatory mechanisms for HDL-mediated reverse cholesterol transport and plasma HDL-C levels, advancing our knowledge on the effects of HDL in pathogenesis and progression of cardiovascular diseases.

Regular checking blood lipids may be served as the important approach for the risk assessment and prevention of the atherosclerotic cardiovascular disease (ASCVD). It has been emphasized by several dyslipidemia management guidelines that the low density lipoprotein cholesterol (LDL-C) was the primary intervention target for prevention of ASCVD risk. Recent studies have demonstrated that small dense low density lipoprotein (sdLDL) or sdLDL cholesterol (sdLDL-C) levels as the biomarker for the prediction and risk assessment of ASCVD may be more sensitive than LDL-C. The isolation and detection methods of sdLDL or sdLDL-C were developed from the traditional ultracentrifugation or gel electrophoresis to the efficient, fast, accurate automated processing system. The continuous advances and popularization in analytical techniques of LDL subcomponents provided new methods and ideas for their application in the risk assessment and prevention of ASCVD.

Objective To investigate FIB and D-D with GRACE risk score to predict the risk of acute coronary syndrome (ACS)during hospitalization.Methods Plasma FIB,D-D and GRACE risk score were measured in 90 patients with ACS and 23 healthy controls,the number of coronary artery lesions of ACS patients also was obtained.Results The results of FIB,D-D levels and GRACE risk score in ACS group were 2.77±0.79 g/L,1.67±2.13 mg/L,147.19±32.50,respective-ly.Compared to controls,FIB,D-D and GRACE risk score in ACS group were significantly increased (t=6.256,6.465, 10.317,all P<0.001).There were significant differences in plasma D-D and FIB levels in different risk stratification (F=18.475,9.426,all P<0.001).FIB (r=0.485,P<0.000 1)and D-D (r=0.357,P<0.000 6)levels were found positively related with GRACE risk score.Conclusion Pasma FIB ,D-D levels and GRACE risk score were increased in ACS group. FIB and D-D can be used as indicators to predict the risk stratification for ACS patients,and D-D was better than FIB.

Background It is well known that tissue factor (TF) is expressed in tumor cells and neovascular endothelial cells of tumor.It plays an important role in the formation of new blood vessels as well as the growth and metastasis of tumor.However,whether TF is expressed or not in choroidal melanoma(CM)is unclear.Objective This study is to investigate the expression of TF in a choroidal melanoma cell line and human choroidal melanoma.Methods The expression of TF was studied in the optimal choroidal melanoma-1 (OCM-1) cell line and ten specimens from CM patients using immunhistochemistry.Ten normal eye specimens from donators were used as controls.Results The TF protein was mainly expressed in the cytoplasm.It is over-expressed in OCM-1 cells with positive rate of 85.33±5.47%.Hyper-expression of TF also was found in human choroidal melanoma with a positive rate of 41.60±14.17%.The integrated optical density (IOD) of positive cells in CM was 33853.67±16445.30,and only 5.65±4.26% of positive cells was found in normal human choroidal tissue.The IOD of TF expression in normal human choroidal tissue was 426.43±316.62.Conclusion The overexpression of TF in CM cells may be a new immunotherapy target for CM treatment.

Objective To investigate the relationship of nuclear factor kappa B(NF-κB),Bcl-2 and Bax with limb function after acute spinal cord injury in rats. Methods Forty-eight rats were divided at random into a control group and an experimental group with 24 rats in each.The spinal cords of the rats in the experimental group were injured at the T8,9,10 level through moderate compression.Four hours,8 h,and 1,3,7 and 14 days after the injury,4 rats were selected randomly from each group and graded with a BBB score.They were then sacrificed and their spinal cords were collected.Immunohistochemical measurements were used to observe the expression of NF-κB, Bcl-2 and Bax. Results NF-κB,Bcl-2 and Bax were observed in the injured spinal nerve cells of rats in the exper imental group but were absent in the control group.After injury,the expression of these factors increased at first and then decreased.BBB scores for limb function increased gradually.No correlation was found between the changes in NF-κB and Bcl-2,but the expression of NF-κB was positively correlated with that of Bax.There was negative correla tion between NF-kB levels and BBB scores,and between NF-kB levels and the ratio of Bcl-2 to Bax. Conclusion In rats,there is a close negative correlation between NF-kappa B levels,the ratio of Bcl-2/Bax and limb function after acute spinaI cord iujury.

Objective To investigate the clinical outcomes of different managements of complete rupture of the deltoid ligament associated with supination-external rotation ankle fracture.Methods From January 2010 to June 2014,33 cases of complete rupture of the deltoid ligament associated with supination-external rotation ankle fracture were treated with open reduction and internal fixation.According to the different managements of the complete rupture of the deltoid ligament,the patients were divided into 4 groups:9 cases in the non-repair group,7 cases in the superficial layer repair group,9 cases in the deep layer repair group,and 8 cases in the complete repair group.All the patients took anteroposterior,lateral and gravity stress radiographs preoperatively and postoperatively.The 4 groups were compatible in preoperative general data (P ＞ 0.05).The 4 groups were compared in terms of operation time,medial clear space and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score.Results All the patients were followed up for 6 to 18 months (average,13.7 months).All wounds healed at the first stage without any infection.All fractures united primarily after 3 to 9 months (average,4.7 months).The operation time for the superficial layer repair group was significantly longer than for the non-repair group,but significantly shorter than for the deep layer repair and the complete repair groups (P ＜ 0.05).In gravity stress radiographs,there was no significant difference in medial clear space among the 4 groups (P ＞ 0.05),but there were significant differences before and after operation in the 4 groups (P ＜ 0.05).The postoperative AOFAS ankle-hindfoot score in the repair groups was significantly higher than in the non-repair group and the superficial layer repair group(P ＜ 0.05).Conclusion To achieve satisfactory outcomes for patients with complete rupture of the deltoid ligament associated with supination-external rotation ankle fractures,anatomic open reduction and rigid internal fixation is necessary,and repair of the deltoid ligament,especially its superficial layer,is a valuable contribution.

Objective To investigate altered levels and clinical significance of serum miR-133a in patients with acute coronary syndrome ( ACS ) and stable coronary artery disease ( SCAD ) .Methods Retrospective study.Serum miR-133a levels were determined by TaqMan quantitative reverse-transcription PCR assay in 64 ACS, 62 SCAD patients who were admitted to Jinling Hospital from October 2011 to October 2012 and 70 normal controls who had contemporaneously visited Jinling Hospital for routine examination .The ACS and SCAD patients were diagnosed according to the European Society of Cardiology guidelines .Serum lipid/lipoprotein profiles , myonecrosis biomarkers and Gensini scores were also analyzed .The area under curve ( AUC) and 95%confidence interval ( CI) were calculated using ROC analyses .The odds ratio ( OR) and 95%CI were calculated using the multivariate logistic regression analyses .Results Compared with the controls [ΔCt:1.00 ±0.05], serum miR-133a levels were significantly increased in both ACS [ΔCt:2.34 ±0.24] (t=6.059, P<0.001) and SCAD [ΔCt:1.45 ±0.13] (t=3.265, P=0.001) patients.The miR-133a levels in ACS patients were significantly higher than in SCAD patients (t=3.133, P=0.002). Serum miR-133a were positively correlated with levels of creatine kinase MB ( CK-MB) ( r=0.402, P<0.001), cardiac troponin I (cTNI) (r=0.410, P=0.001) and Gensini scores (r=0.438, P<0.001). ROC curve analyses showed that the AUC of miR-133a for differentiating coronary artery disease (CAD) and controls was 0.717 (95%CI:0.645-0.788, P<0.001) and the AUC for differentiating ACS and SCAD was 0.667 (95% CI:0.573-0.761, P=0.001).Logistic regression analyses revealed that high miR-133a levels were closely associated with the presence of ACS ( OR=6.00, 95% CI:1.93 -18.67, P=0.002) and SCAD (OR=2.81, 95%CI:1.03-7.68, P=0.044), and also had statistical significance for differentiating ACS and SCAD (OR=2.13, 95% CI:1.20-3.78, P=0.010), after adjustment for the age, gender and serum lipid/lipoprotein levels.Conclusions Serum miR-133a levels were significantly elevated in CAD patients, and ACS patients exhibited the more significant increase .Serum miR-133a may be function as the potential biomarker for the disease assessment and judgement .
