BACKGROUND: Biomarkers-based prediction of long-term risk of acute coronary syndrome (ACS) is scarce. We aim to develop a risk score integrating clinical routine information (C) and plasma biomarkers (B) for predicting long-term risk of ACS patients. METHODS: We included 2729 ACS patients from the OCEA (Observation of cardiovascular events in ACS patients). The earlier admitted 1910 patients were enrolled as development cohort; and the subsequently admitted 819 subjects were treated as validation cohort. We investigated 10-year risk of cardiovascular (CV) death, myocardial infarction (MI) and all cause death in these patients. Potential variables contributing to risk of clinical events were assessed using Cox regression models and a score was derived using main part of these variables. RESULTS: During 16,110 person-years of follow-up, there were 238 CV death/MI in the development cohort. The 7 most important predictors including in the final model were NT-proBNP, D-dimer, GDF-15, peripheral artery disease (PAD), Fibrinogen, ST-segment elevated MI (STEMI), left ventricular ejection fraction (LVEF), termed as CB-ACS score. C-index of the score for predication of cardiovascular events was 0.79 (95% CI: 0.76-0.82) in development cohort and 0.77 (95% CI: 0.76-0.78) in the validation cohort (5832 person-years of follow-up), which outperformed GRACE 2.0 and ABC-ACS risk score. The CB-ACS score was also well calibrated in development and validation cohort (Greenwood-Nam-D'Agostino: P = 0.70 and P = 0.07, respectively). CONCLUSIONS CB-ACS risk score provides a useful tool for long-term prediction of CV events in patients with ACS. This model outperforms GRACE 2.0 and ABC-ACS ischemic risk score.

ObjectiveThe aspartate aminotransferase-to-platelet ratio index （APRI） and liver fibrosis-4 index （FIB-4） have been used for noninvasive prediction of liver fibrosis and cirrhosis and both indexes exhibit a high degree of accuracy in the the prediction of the prognosis of hepatocellular carcinoma（HCC）patients after hepatectomy.. This study aims to explore the predictive values of APRI and FIB-4 in the occurrence of posthepatectomy liver failure （PHLF） in HCC patients. MethodsThe clinical data of 426 patients with HCC who underwent hepatectomy in our hospital were retrospectively analyzed. Laboratory data were collected from patients within 2 weeks prior to hepatectomy. APRI， FIB-4 and Child-Pugh scores were calculated. Receiver operating characteristic （ROC） curves were used to determine the AUC values and optimal cut-off values of APRI， FIB-4 and Child-Pugh scores. Univariate and multivariate logistic regression analyses were employed to identify the independent risk factors for PHLF， and the predictive values of APRI and FIB-4 on PHLF were compared. ResultsA total of 48 patients （11.3%） developed PHLF. Multivariate analysis showed that major hepatectomy （≥3 segments resection）， blood loss >400 mL， total bilirubin （TBIL）， platelet （PLT）， fibrinogen （Fib）， APRI and FIB-4 were independent risk factors for PHLF. ROC curve analysis revealed that APRI （AUC = 0.816） and FIB-4 （AUC = 0.728） had better ability to predict PHLF than Child-Pugh score （AUC = 0.566； P<0.001）. ConclusionsPreoperative APRI and FIB-4 are independent predictors of PHLF in HCC patients after hepatectomy and have good predictive values.

OBJECTIVETo investigate the current status of the application of H-magnetic resonance spectroscopy (H-MRS) in neonates with hypoxic-ischemic encephalopathy (HIE), and to describe the trend of research in the field.

METHODSPubMed, EMBASE, and Web of Science were searched for English articles published up to January 10, 2018, with the combination of key words and MeSH terms. The articles were screened according to inclusion and exclusion criteria. Excel 2016, Bicomb 2.0, and VOSviewer1.6.6 were used to analyze the key words, to perform a cluster analysis of hot words, and to plot the knowledge map.

RESULTSA total of 66 articles were included, and 27 high-frequency key words were extracted. The results showed that H-MRS was mainly used in four directions of the clinical practice and scientific research on HIE. In clinical practice, H-MRS attracted wide attention as a clinical examination for HIE and a tool for prognostic evaluation; in scientific research, H-MRS was used in animal experiments and studies associated with mild hypothermia therapy.

CONCLUSIONSAs an auxiliary means of magnetic resonance imaging, H-MRS plays an important role in investigating the pathogenesis of neonatal HIE, improving existing therapies, and evaluating the prognosis of neonates with HIE.

BACKGROUNDAngiogenesis is the formation of new blood vessels to supply nutrients to tumors. Vascular endothelial growth factor (VEGF) and cluster of differentiation 34 (CD34) are important signaling proteins involved in angiogenesis. Many studies have demonstrated that VEGF and CD34 are related to tumor progression. This study focused on the relationship between VEGF, CD34, and perioperative hemorrhage in patients with gastric cancer.

METHODSTo observe the relationship between VEGF and CD34, we tracked 112 patients with advanced gastric cancer for 5 years to assess factors related to hemorrhage, using immunohistochemistry. The results were subjected to statistical analysis using a 2 × 2 contingency table, logistic regression, and receiver operating characteristic (ROC) test.

RESULTSThe concentrations of VEGF and CD34 were critically correlated with perioperative hemorrhage and neural invasion in patients with gastric cancer (P < 0.05). Expression of VEGF and CD34 was related (P < 0.05, χ2 = 6.834). VEGF and CD34 co-expression strongly increased the risk of preoperative bleeding (area under the ROC curve >0.7, P < 0.05).

CONCLUSIONSExpression of VEGF and CD34 was critically correlated with perioperative hemorrhage in gastric cancer patients. Co-expression of VEGF and CD34 could be an effective indicator for evaluating the risk of perioperative bleeding in gastric cancer patients.

OBJECTIVETo investigate the effects of 17-β estradiol (E(2)) and Porphyromonas gingivalis (Pg) W83 on the expression of interleukin (IL)-6 and IL-8 in human periodontal ligament cells (hPDLC).

METHODSPrimary cultures of hPDLC were established and the cells of passage four were treated with 10(-10) mol/L E(2), 10(-7) mol/L E(2) or PgW83 individually or E(2) combined with PgW83. The expression levels of IL-6 and IL-8 protein at 12 h and 24 h were measured with enzyme-linked immunosorbent assay and the levels of mRNA at 24 h were detected with real-time reverse transcriptase polymerase chain reaction.

RESULTSThe expression level of IL-6 reached (2482.88 ± 26.53) ng/L in hPDLC treated with Pg at multiplicity of infection (MOI) of 100 for 24 h, which was significantly higher than that in hPDLC treated with Pg at MOI of 10:1 [(734.09 ± 87.90) ng/L, P = 0.000], the controls [(425.8 ± 77.25) ng/L, P = 0.000] and that in hPDLC treated with Pg at MOI of 100 for 12 h [(1157.50 ± 234.65) ng/L, P = 0.000]. The expression level of IL-8 reached (4965.81 ± 1072.55) ng/L in hPDLC treated with Pg at MOI of 100 for 24 h, which was significantly higher than that in hPDLC treated with Pg at MOI of 10 [(803.51 ± 162.08) ng/L, P = 0.007], the controls [(400.75 ± 2.27) ng/L, P = 0.005] and that in hPDLC treated with Pg at MOI of 100 for 12 h [(1431.12 ± 82.78) ng/L, P = 0.001]. E(2) did not show remarkable effect on the expressions of IL-6 and IL-8. E(2) combined with Pg (MOI = 100:1) significantly promoted the expression levels of IL-6 at 24 h while did not influence those of IL-8. The relative mRNA level of IL-6 in hPDLC treated with 10(-10) mol/L E(2) or 10(-7) mol/L E(2) combined with Pg were 0.49 ± 0.15 (P = 0.021)and 0.53 ± 0.16 (P = 0.036) individually, which were significantly higher than that treated with Pg alone, 0.19 ± 0.06. The protein level of IL-6 in hPDLC treated with 10(-10) mol/L E(2) or 10(-7) mol/L E(2) combined with Pg were (5512.66 ± 1022.07) ng/L (P = 0.012) and (6988.78 ± 2279.13) ng/L (P = 0.000) individually, which were significantly higher than that treated with Pg alone, (3138.46 ± 183.72) ng/L.

CONCLUSIONSPgW83 significantly increased the expression levels of IL-6 and IL-8 in hPDLC in a dose-and time-dependent manner. Without the infection of periodontal pathogens, estrogen may exert no effect on the expression of IL-6 and IL-8 while it may promote the expression of IL-6 in hPDLC when combined with Pg, which may in turn promote the process of periodontal inflammation.

OBJECTIVESTo investigate the effects of astilbin on the expressions of TNF alpha and IL-10 during liver warm ischemia-reperfusion injury.

METHODSC57BL/ 6 mice were randomly divided into 4 groups (n = 8): sham-operated group (Sham), model control group(I/R), low dosage of astilbin treatment group (10 mg/kg) and high dosage of astilbin (40 mg/kg) treatment group. The treatment group mice were intraperitoneally injected with 10 or 40 mg/kg astilbin 24 hours and one hour before Ischemia, the hepatic ischemia-reperfusion model were thus established. After jn90 of min ischemia and 6 h reperfusion of the partial hepatic lobe, the expressions of TNF alpha and IL-10 in liver tissues collected from the experimental groups were detected by Western blot and semiquantitative RT-PCR.

RESULTSThe expression of TNF alpha protein in liver tissues gradually decreased in treatment groups (low and high dosages of astilbin treatment groups) as compared to the I/R model control group. Similar results were observed in the mRNA expressions of these genes as determined by semiquantitative RT-PCR (P less than 0.05 for low dosage group; P less than 0.01 for high dosage group). Compared with the I/R model control group, the expression of IL-10 was increased in both treatment groups (low dosage group P less than 0.05; large dosage group P less than 0.01).

CONCLUSIONTreatment with astilbin decreases TNF alpha expression but induces IL-10 expression in liver during warm ischemia-reperfusion injury.

OBJECTIVETo explore the relationship between methyl-tetra-hydrofolic acid (MTHFR) 677 gene polymorphism and the risk of stomach cancer.

METHODSA population based case-control study was conducted and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to detect its genotypes.

RESULTSAmong cases with stomach cancer, the frequency of C/C, C/T, T/T genotype were 25.8%, 54.6%, 19.6%, compared with controls as 34.5%, 50.9%, 14.6% respectively. Using C/C genotype as reference, the OR of C/T or T/T genotype was 1.52 (95% CI: 1.04 - 2.23). 53.3% C and 46.7% T allele were distributed in stomach cancer cases, while 60.0% C and 40.0% T in controls. The OR for T allele in relation to C allele was 1.31 (1.02 - 1.69) when C allele was used as reference. In addition, the present study showed that MTHFR677 AnyT genotype might interact with smoking, moldy food intake, wheat porridge intake, eating salty food and Hp CagA infection to increase the risk of stomach cancer. No interaction was observed between MTHFR677 AnyT genotype and alcohol drinking or green tea intake.

CONCLUSIONMTHFR677 AnyT genotype, might increase the risk of stomach cancer development and the genotype might also interact with other environmental risk factors to increase the risk of stomach cancer.
