Objective: To explore the early diagnostic value of thrombus molecular markers in thrombosis ofpatients with malignant tumors and to evaluate their risk factors. Methods: Diagnostic research.A total of 1366 patients (including lung cancer, breast cancer and colorectal cancer,) were randomly selected in the Red Flag Hospital of Mudanjiang Medical College and Mudanjiang Cancer Hospitalfrom September 2009 to February 1919. Among them, 562 were males and 804 were females with average age (59.45±15.10) years old. The control group consisted of 70healthy donors (35 males and 35 females, with an average age of (49.60±19.12) years old), including 69 cases of venous thrombosis (thrombotic group, 32 males and37 females, with an average age of (61.20±15.71) years old).Chemoluminescent enzyme immunoassay was used to detect thromboregulatory proteins(TM), thrombin-antithrombin complexes(TAT), tissue plasminogen activators/inhibitors -1 complexes(t-PAIC), plasminase-anti-fibrinolysis complexes(PIC) in venous plasma. According to the sensitivity and specificity of each marker, the receiver′s work characteristic curve was drawn to evaluate its diagnostic performance. Cox regression analysis was used for single-factor and multi-factor risk analysis. Results: The incidence of venous thromboembolism(VTE) in patients with different types of malignant tumors was statistically significant, with lung cancer being the highest, followed by colorectal cancer and breast cancer(P<0.05). The levels of TM, TAT, t-PAIC and PIC were significantly higher in the lung, breast and colorectal thrombosis group than in the control group. The differences were statistically significant(all P<0.05). The optimal cut-off level for TM is 10.57 IU/ml(sensitivity 50.30%, specificity 75.50%, AUC=0.671), and the optimal cut-off level for TAT is 4.16 ng/ml(sensitivity is 80.30%, specificity is 62.80%, AUC=0.757).The optimal truncation level for t-PAIC is 11.44 ng/ml(sensitivity 52.50%, specificity 84.00%, AUC=0.682), and the optimal truncation level for PIC is 1.18μg/ml(sensitivity 67.20%, specificity is 79.50%, AUC=0.790). The combined detection of the four molecular markers has the best sensitivity and diagnostic performance(86.90%, AUC=0.807). Age, stage, metastasis, surgery, tumor diameter, and PIC levels are independent factors that affect the occurrence of VTE in malignant tumors (all P<0.05). Conclusions Different types of malignant tumors have different rates of thrombosis. The combined detection ofTM, TAT, t-PAIC and PIC have the best diagnostic performance, and can be used as a new early diagnosis method for VTE in malignant tumors. Age, stage, metastasis, surgery, and tumor diameter are risk factors for VTE in malignant tumors. PIC levels can be used as a reliable markerfor the risk of VTE in patients with malignant tumors within 6 months.

Objective To investigate the correlation between plasma homocysteine(Hcy) and long term occurrence of main adverse cardiac events(MACE) in the patients with acute myocardial infarction(AMI).Methods A total of 326 inpatients with AMI in the cardiology department of this hospital from Mar.2012 to Dec.2014 were continuously included.The related laboratory biochemical indicators such as Hcy were detected according to the standard flow process by the hospital clinical laboratory department.The Hcy level and MACE occurrence rate were performed the receiver operating characteristic(ROC) curve analysis.The research subjects were divided into the Hcy(L) group and Hcy(H) group according to the cut-off value 11.69μmol/L.The base line data of all subjects were collected and the follow up was conducted for recording MACE.Results The plasma N-terminal pro-brain natriuretic peptide (NT-ProBNP) level in the Hcy(L) group was significantly lower than that in the Hcy(H) group[-(501.46-±-118.35)pg/mL vs.(1 324.11 ± 523.13) pg/mL,P =0.02],while the left ventricular ejection fraction(LVEF) was significantly higher than that in the Hcy(H) group[(55.23 ± 9.48) ％ vs.(50.79 ± 10.68) ％,P =0.03].After 1-year follow up,LVEF in the Hcy(H) group was significantly decreased compared with the base line [(45.32±10.18)％ vs.(50.79±10.68)％,P＜0.05],moreover the MACE occurrence risk in the Hcy(H) group was significantly higher than that in the Hcy(L) group,the difference after correcting the related confounding factors had statistical significance (P=0.048),but LVEF and minor axis shortening rate of left ventricle(FS) in the Hcy(L) group had no obvious difference compared with the base line data[(54.43 ± 10.68)％ vs.(55.23± 9.48) ％,(28.56±6.21) ％ vs.(29.22±5.30) ％,P＞0.05].Conclusion The risk of long term MACE occurrence in the patients with AMI complicating plasma high Hcy level is obviously increased compared with that in the patients with plasma low Hcy level and the prognosis is poor,prompting that plasma high Hcy level is one of possible independent predicting factors for poor prognosis in the patients with AML But its action mechanism and whether the Hcy interventional therapy improving prognosis of AMI patients still need to further study.

Objective:To investigate the correlation between interleukin-27(IL-27)polymorphisms and coronary heart disease(CHD)in the Guangxi Zhuang population.Methods:A total of 1 218 subjects were enrolled in this case-control study, and 571 cases were in the CHD group and 647 were in the control group.The Sequenom MassArray system was used to genotype IL-27 single nucleotide polymorphisms(SNPs), and other biochemical parameters were tested by using the standard protocol in the laboratory of our hospital.The correlation between IL-27 SNPs and CHD was evaluated by Logistic regression analysis, and risk factors including age, smoking, drinking, history of hypertension, history of diabetes mellitus and family history of CHD were adjusted in this model.Methods:Logistic regression analysis results indicated that the risk of CHD was elevated in subjects with the CC genotype of IL-27 rs428253, compared with those with the GG genotype( OR=2.18, 95% CI: 1.09-4.37, P<0.05). After adjustment for the related risk factors, the risk of CHD also increased in subjects with the CC genotype of IL-27 rs428253, compared with those with the GG genotype( R=2.82, 95% CI: 1.31-6.07, P<0.05). IL-27 rs4740, rs17855750, rs181206 and rs40837(all P>0.05)polymorphisms had no correlation with CHD in the Zhuang population, and there were no significant differences in C-reactive protein, total cholesterol, triglyceride or low-density lipoprotein cholesterol levels between CHD patients and controls with different genotypes of IL-27 rs428253(all P>0.05). Conclusions:IL-27 rs428253 polymorphism is correlated with the risk of CHD in the Guangxi Zhuang population.
