Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Objective To explore the predictive value of neutrophil gelatinase associated lipocalin (NGAL) for contrast-induced acute kidney injury (CI-AKI) after emergency percutaneous coronary interventions (PCI) in patients with relative normal renal function.Methods A total of 73 patients with relative normal renal function undergoing PCI were enrolled in this prospective multicenter clinical study.Serum NGAL was measured by point-of-care test.Receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of NGAL for CI-AKI.Results CI-AKI occurred in 5 patients (6.85％).The concentration of NGAL was higher in the CI-AKI group than in the non-CI-AKI group.ROC curve indicated that the area under the receiver operating characteristic was 0.755,0.761 and 0.809,respectively.Conclusions Serum NGAL at baseline,4 h and 8 h after procedure are served as a good biomarker for early diagnosis of CI-AKI after PCI.Therefore,NGAL might become an early and quick marker for CI-AKI in the future.

Objective:To investigate the predicting value of European system for cardiac operative risk evaluation ( EuroSCORE ) and sino system for coronary operative risk evaluation ( SinoSCORE ) in early quality of life of patients after coronary artery bypass surgery (CABG).Methods:A total of 218 consecu-tive patients who underwent CABG from March 2010 to January 2013 were evaluated with both systems before operation .Health related quality of life ( QoL) was estimated by using 36-item short form health survey ( SF-36) preoperatively and postoperatively in order to evaluate the predicting value of the two sys -tems in early post-operative QoL.Calibration was evaluated by Hosmer-l,emeshow goodness-of-fit test. Discrimination was tested by determining the area under the receiver operating characteristic ( ROC ) curve .Results:There was no significant difference between the accumulation of the EuroSCORE and SinoSCORE in the all patients (t=-0.904, P=0.368), When using Wilcoxon test on life quality in the preoperative and postoperative patients respectively ,the data showed that the quality of life improved significantly in various dimensions of the postoperative patients (Z=-2.886, P<0.001).Except for bodily pain (BP) and mental health (MH), statistically significant correlation was found between the preoperative risk evaluation scores and the postoperative QoL scores (r:-0.203 to -0.493, P<0.05). Logistic regression analyses indicated that both the scores emerged as the independent predictor for a relatively worse QoL ( OR>1 , P<0 .05 ) .Furthermore , the EuroSCORE predicted the outcome with a higher OR.For SinoSCORE the Hosmer-Lemeshow test was significant (P=0.628) and the area under ROC curve was 0.754.For the EuroSCORE the Hosmer-Lemeshow test was significant (P=0.538) and the area under ROC curve was 0.854.Conclusion:Both EuroSCORE and SinoSCORE could be viewed as a predictor for several aspects of postoperative QoL , while EuroSCORE might have a greater predicting value.

BACKGROUNDThoracic endovascular aortic repair (TEVAR) is an emerging treatment modality, which has been rapidly embraced by clinicians treating thoracic aortic disease. However, the clinical manifestations of systemic inflammatory response after TEVAR as post-implantation syndrome (PIS) resemble the perioperative infection. This study aimed to evaluate changes and diagnostic value of procalcitonin (PCT) and other traditional inflammatory markers for infections after TEVAR.

METHODSWe conducted a prospective clinical study that enrolled 162 consecutive aortic dissection cases, who underwent TEVAR in our institution between July 2011 and November 2012. The PCT, C-response protein (CRP), erythrocyte sedimentation rate (ESR) and blood routine examination were monitored before the operation and on days 1, 2, 3 and 5 after the operation. The diagnosis of infection was confirmed by the infection control committee with reference to Hospital Acquired Infection Diagnostic Criteria Assessment, released by the Ministry of Health of the People's Republic of China.

RESULTSPost endovascular repair of thoracic aorta, PCT changes significantly at different time points (χ(2) = 13.225, P = 0.021), without significant difference between the PIS group and the control group (0.24 ± 0.04 vs.0.26 ± 0.10, P = 0.804). PCT values were significantly higher in the first day after TEVAR than the preoperative levels (0.18 ± 0.03 vs. 0.11 ± 0.02, P < 0.001). Compared with PIS patients, the level of PCT, CRP, White blood cell (WBC) and neutrophil (NEU) in the infection patients elevated significantly (relatively χ(2) = 6.062, P = 0.048; χ(2) = 6.081, P = 0.048; χ(2) = 11.030, P = 0.004; χ(2) = 14.632, P = 0.001). According to the ROC analysis, the PCT levels in the first day after TEVAR (AUC = 0.785, P = 0.012) had better predictive values of infection than WBC, NEU CRP and ESR (AUC = 0.720, P = 0.040; AUC = 0.715, P = 0.045; AUC = 0.663, P = 0.274; AUC = 0.502, P = 0.991). The best predictive index was the changes of PCT between preoperative and postoperative (PCT), which possess AUC as 0.803 (P = 0.014). And PCT = 0.055 could be considered as an infection diagnosis cutoff value with a sensitivity of 83.3% and specificity 69.0%.

CONCLUSIONSPCT provides better diagnostic value of infection compared with other inflammatory markers. The potential applications of PCT in differential diagnosis of PIS and infection after percutaneous TEVAR deserve further studies.

OBJECTIVETo study the relationship between carbon dioxide combining power(CO₂-CP) and contrast-induced acute kidney injury (CI-AKI) in patients with ST segment elevation myocardial infarction and undergoing percutaneous coronary intervention.

METHODSWe retrospectively analyzed 174 patients admitted to our hospital from March 2012 to August 2013 with ST segment elevation myocardial infarction and underwent emergency percutaneous coronary intervention. Patients were divided into three tertiles according to pre-operative CO₂-CP: T1 (CO₂-CP < 22.62 mmol/L), T2(CO₂-CP 22.62-24.30 mmol/L), T3(CO₂-CP > 24.30 mmol/L). Baseline clinical data, CI-AKI incidence, in-hospital mortality and dialysis rate were compared among groups. An increase in serum creatinine of >26.4 µmol/L and/or >50% from baseline within 48 hours after contrast exposure was defined as CI-AKI. Univariate logistic regression analysis was used to identify the risk factors of CI-AKI. The relationship between CO₂-CP and CI-AKI was assessed by multivariate logistic regression analysis. Receiver operating characteristic curve was used to identify the optimal cutoff of the CO₂-CP for predicting CI-AKI.

RESULTSCI-AKI occurred in 25 (14.4%) patients, and lower CO₂-CP was related to higher incidence of CI-AKI (27.6% (16/58) in group T1, 5.3% (3/57) in group T2, 1.7 % (1/59) in group T3, P = 0.002) and higher in-hospital mortality (10.3% (6/58) vs. 0 and 1.7% (1/59), P = 0.010). Dialysis rate was similar among 3 groups (5.2% (3/58) vs. 0 and 1.7% (1/59), P = 0.168). The incidence of CI-AKI was significantly associated with CO₂-CP < 22.00 mmol/L in univariate analyses (OR = 6.767, 95% CI 2.731-16.768, P < 0.001). After adjusting for potential confounding risk factors, CO₂-CP < 22.00 mmol/L remained significantly associated with the incidence of CI-AKI (OR = 5.835, 95%CI 1.800-18.914, P = 0.003) in multivariate logistic regression. ROC analysis revealed that the optimal cutoff of CO₂-CP to predict CI-AKI was 22.00 mmol/L (sensitivity 64.0%, specificity 79.1%, AUC = 0.714).

CONCLUSIONSPre-percutaneous coronary intervention CO₂-CP in patients with ST segment elevation myocardial infarction undergoing percutaneous coronary intervention is related to CI-AKI. CO₂-CP < 22.00 mmol/L predicts higher risk of CI-AKI in this patient cohort.
