Treatment of chronic hepatitis B (CHB) with nucleos(t)ide analogs (NA) and interferonα (IFNα) can lead to a significant suppression of viral replication， as well as reduced risk of disease progression and hepatocellular carcinoma. However， challenge remains regarding curing CHB because hepatic covalently closed circular DNA can not be completely eradicated. Discovering new drugs targeted hepatitis B virus may enable the possibility of functional curing CHB in future. Among available therapeutic strategies， switching to or sequential combination with IFNα in patients with longterm NA treatment can induce increased percentages of responses， even make the likelihood of functional cure in a proportion of patients.

Objective To observe the characteristics of plasma amino acids in patients with HBVrelated chronic liver disease， and to investigate the relationship between plasma amino acids with the severity of liver disease and to guide the targeting management for the patients. Methods The level of plasma amino acids， liver function， serum NH3 were measured in 35 cases of HBVrelated chronic liver disease and 10 healthy controls were tested as well. The characteristics of amino acid spectrum， especially the changes of citrulline， ornithine and ammonia were analyzed. Results There was no obvious imbalance of plasma amino acids for most of the patients with chronic hepatitis B. But the blood level of aromatic amino acid increased gradually as the disease moved to cirrhosis and liver failure. At the same time， branched chain amino acids / aromatic amino acids ratio decreased significantly. Comparing with the normal control， the blood levels of ornithine， citrulline and NH3 in patients with HBVrelated liver disease increased gradually. Conclusion Plasma amino acids levels may reflect the state of amino acid metabolism in patients with chronic HBVrelated liver disease. Branched chain amino acids / aromatic amino acids ratio， ornithine and citrulline levels may have some value in assessing the disease severity， predicting the hepatic encephalopathy and guiding the clinical treatment for the liver patients.

Objective To investigate the effects of lymphocyte to monocyte ratio (LMR) on prognosis assessment of patients with nonHodgkin lymphoma (NHL). Methods Fiftysix patients were enrolled and classified into two groups according to the median value (2.17) of LMR. Multivariate analysis was used to evaluate the association of age， gender， international prognostic index (IPI)， and absolute value of cell subsets in peripheral blood with progress free survival (PFS) and overall survival (OS). Results The two year probabilities of PFS and OS were （55.7±7.7）% and （76.1±6.4）%， respectively. Multivariate analysis showed that LMR was associated with PFS (HR=0.167，95%CI=0.0560.503，P=0.001). Factors associated with OS included LMR (HR=0.120，95%CI=0.0140.998，P=0.050) and IPI (HR=4.763， 95%CI=0.98223.114，P=0.053). Conclusion Our results suggested that LMR is a simple and feasible biomarker during preliminary diagnosis that could be used to predict clinical outcomes of patients with nonHodgkin lymphoma.

Objective To explore the association between the 3'UTR +3908 C>T polymorphism of CNOT6 and susceptibility to gastric cancer in Han population. Methods The casecontrol study consisted of 960 patients with histopathologically verified primary gastric adenocarcinoma and age and sexmatched healthy 972 controls in Chinese Han. The genotypes were determined by polymerase chain reactionbased restriction fragment length polymorphism (PCRRFLP). The associations between genotype and risk of developing gastric cancer were estimated by calculating the odds ratio (OR) and the 95% confidence interval (95% CI) with logistic regression models. Results For rs10069， subjects with TT/CT genotype had a decreased risk for developing gastric cancer compared with CC genotype(OR=0.74; 95%CI=0.600.93). The association was more pronounced among individuals with <56 years of age. Moreover， a multiplicative joint effect between the CNOT6 SNP and Helicobacter pylori infection that intensified the risk was observed (OR for the presence of both CC genotype and H. pylori infection=2.32; 95%CI=1.413.82). No significant association was observed between the polymorphism and stage and grade of the cancer. Conclusion The +3908 C>T polymorphism of CNOT6 is associated with susceptibility to gastric cancer.

Objective To investigate the curative effect and the security of applying tirofiban before primary percutaneous coronary intervention (PCI) in patients with ST segment elevation myocardial infarction (STEMI) suffering no/slow reflow phenomenon. Methods A total of 296 patients with STEMI were selected into this study. All patients underwent primary PCI and applied tirofiban by intravenous route. According to the different mediction time of the tirofiban， all patients were divided into preoperative treatment group and intraoperative treatment group. Blood flow condition of the infarction related artery (IRA) of preoperation and postoperation， postoperative left ventricular ejection fraction (LVEF)， the incidence of major adverse cardiovascular events (MACE) bleeding and serious thrombopenia (PLT<10×109/L) during hospitalization were analysed in both groups. Results The ratio of TIMI 3 of IRA in preoperative treatment group was significantly higher than those of intraoperative treatment group in preoperation (74.7% vs 47.2%，P<0.05) and postoperation (98.9% vs 93.2%，P<0.05). The postoperative left ventricular ejection fraction was significantly higher in preoperative treatment group than in intraoperative treatment group (58.31±5.35)% vs (52.93±6.01)%(P<0.05). There were no significant difference in the incidence of MACE， bleeding and serious thrombopenia during hospitalization in both groups. Conclusion Preoperative tirofiban treatment can reduce the incidence of no and slow reflow phenomenon and protect the heart function， additionally， preoperative tirofiban does not increase the incidence of postoperative bleeding in patients with STEMI.

Objective To analyze the combination of preoperative plasma levels of fibrinogen(Fbg) and neutrophiltolymphocyte ratio (COFNLR) with clinicopathologic characteristics as well as the prognosis of nonsmallcell lung cancer (NSCLC) patients after curative resection. Methods The clinical data of 122 patients with NSCLC who underwent curative resection in our hospital were retrospectively analyzed. A total of 122 patients with NSCLC were divided into three groups based on the criteria of COFNLR: COFNLR 0 group， n=49; COFNLR1 group， n=41; COFNLR2 group， n=32. The preoperative COFNLR was calculated by combing the fibrinogen and neutrophiltolymphocyte ratio (NLR). The relationship between the COFNLR and clinicopathological features was studied by chisquare test. The postoperative prognostic factors were analyzed using univariate KaplanMeier analysis and multivariate Cox proportional hazards model. Results The COFNLR was significantly associated with sex， differentiation degrees， T staging， clinical staging（P<0.05）. Univariate analysis showed smoking history， differentiation degrees， T staging， lymph node metastasis， plasma levels of fibrinogen，NLR and COFNLR were associated with survival (P<0.05). Multivariate analysis identified that differentiation degrees， lymph node metastasis and COFNLR as independent prognostic factors of all the patients(all P<0.05).Conclusion Preoperative elevated plasma level of COFNLR indicates tumor progression and poor prognosis in patients with NSCLC. The COFNLR may be a potentially new and useful blood marker for predicting tumor progression and the prognosis of patients with NSCLC.

Objective To evaluate of cystatin C (CysC) on the predictive value of contrast induced nephropathy(CIN) by comparing the changes of creatinine(SCr) and CysC after coronary arteriography (CAG).Methods Patients who underwent coronary angiography and/or percutaneous coronary intervention were enrolled. Serum creatinine and CysC were monitored before angiography， 1 day， 2 days， 3 days after angiography. Glomerular filtration rate was estimated by MDRD. The primary end point was the incidence of CIN. Results A total of 384 patients were enrolled in this study， and 16 (4.17%) patients developed CIN according to the SCr criteria. Serum CysC was significantly higher at 1 day， 2 days，3 days after angiography (P＜0.05). The level of serum CysC was positively correlated with SCr level (r=0.313，P<0.01)， but negatively correlated with eGFR (r=-0.325，P<0.01). The area under ROC curve at 2 days after angiography was 0.833（95%CI=0.7440.992，P＜0.01）， better than 1 day and 3 days after angiography. The best cutoff point was 1.115 mg/L. The area under ROC curve of varying degrees at 2 days after angiography was 0.812（95%CI=0.8020.822，P＜0.01） and the best cutoff point was 12.5%. Conclusion As serum CysC could evaluate the renal function at early period，it could be a sensitive biomarker to evaluate induced CIN. The accuracy of diagnosis CIN in CysC level 2 days after CAG was higher than that 1 day and 3 days after CAG. Moreover， ≥12.5% increase can be used as a cutoff point in CIN diagnosis.
