Objective To explore the disparity of severity of cardiac dysfunction and recovery among different glycometabolic patients in the early phase of acute myocardial infarction (AMI) . Methods Consecutive 111 AMI patients without known diabetes underwent continuous glucose monitoring. Patients with different glycometabolic status were compared in terms of cadiac dysfunction and recovery at admission and 3month follow up. Results Compared to patients with normglycemia and transient hyperglycemia, patitents with persistent hyperglycemia were more likely to grade Killip Ⅱ or above,which were 13.3% (4/30) ,33. 3% ( 12/36) ,55. 6% (25/45), 20. 0% ( 6/30), 41.7% ( 15/36 ) and 93.3% (42/45) ( Ps ＜ 0. 01 ). In-hospital left ventricular ejection fraction (LVEF), mitral valve protodiastolic E peak velocities (E) and its ratio to late diastolic (E/A) decreased significantly ( LVEF :0. 52 ± 0. 02,0. 48 ± 0. 01 and 0. 37 ± 0. 02; E: [0. 65 ± 0. 41]m/s,[0.55 ± 0.02] m/s and [0.39 ±0. 12]m/s;E/A:1. 15 ±0.08,1.02 ±0.06 and 0.61 ±0.02,respectively) ( Ps ＜ 0. 01 ), whereas LVESV and WMSI increased significantly ( LVESV: [25.83 ± 0. 51] ml,[31.26 ± 1.23] ml, [37, 72 ± 1.01] ml; WMSI: 1.5 ± 0. 3,1.8 ± 0. 2 and 2. 6 ± 0. 4, respectively) ( Ps ＜ 0. 01 )There months after AMI,patitents with persistent hyperglycemia were more likely to grade NYHA Ⅱ or above compared to patients with normglycemia and transient hyperglycemia [67.5% (27/40), 10.0% (3/30) and 11.8% (4/34),respectively] (P ＜0. 01 ). Echocardiographic recovery was observed in each group,but less in persistent hyperglycemia patients. Conclusion Cardiac function of patients with persistent hyperglycemia suffered more severely from AMI and difficult to recover.

We investigated the molecular characteristics of the full-length genome of 14 dengue serotype 1 virus (DENV-1)strains isolated in Sino-Myanmar border region in Yunnan Province,China during 2013-2015.Isolation of dengue virus was using C6/36 cell culture method.Viral RNA was extracted from virus isolates,and then the full-length genome was amplified by RT-PCR.The homology and phylogenetic analysis was made on the nucleotide and deduced amino acid sequences by bioinformatics software including ClastalX1.83 and MEGA6 etc.Results showed that fourteen strains of DENV-1 isolated from dengue fever cases,of these,9 strains from Ruili City of Dehong Prefecture,3 from Lincang Prefecture,2 from Kunming City.RT-PCR and sequencing indicated that the full-length genes (10 735 nt) of 14 DENV-1 strains were obtained,and their open reading frame (95-10 271) were coded 3 392 amino acid residues.The genotypes of DENV-1 were revealed by homology and phylogenetic analysis based on structural and non-structural proteins.Thirteen were genotype Ⅰ (G-Ⅰ) (7 from indigenous cases in Ruili and Lincang and 6 from imported case from Myanmar to Ruili,Lincang and Kunming),and 1 G-Ⅲ from imported case from India to Kunming.The phylogenic analysis indicated that the 13 isolates from Yunnan divided into 2 phylogenic subgroups,and they had a closer genetic relationship with the strains isolated from Southeast Asia.The gene sequences of the 13 G-Ⅰ strains have been acquired,the rate of their nucleotide homology and amino acid homology were 97.02 ％-100 ％ and 98.78 ％100 ％ respectively.Compared with 6 strains from Southeast Asia,nucleotide homology and amino acid homology were 96.53％-99.53％ and 97.33％-100％ respectively.Compared with prototype strain (US_Hawaii) of DENV-1,nucleotide homology and amino acid homology were 93.76％-94.45 ％ and 95.86 ％-96.91％ respectively.Compared with US_Hawaii strain,there were 44 and 150 different sites in amino acid of structural and non-structural proteins,respectively.The G-1 of DENV-1 have been popular in Sino-Myanmar border region in Yunnan,2013-2015.They have genetic diversity but multiple transmission sources were from Myanmar,and should strengthen control cross-border spread of dengue fever in this region.It is necessary to further study that change of the amino acid sites of Yunnan strains of DENV-1 is related to its antigenicity and pathogenicity.

Objective:To analyze the prognosis of hepatocellular carcinoma (HCC) patients with thrombocytosis (platelet count ≥350×10 9) after transcatheter arterial chemoembolization (TACE), and the effect of thrombocytosis on the prognosis of patients with HCC after TACE. Methods:Clinical data of 867 patients with HCC admitted to the Department of Interventional Radiology, the Affiliated Hospital of Xuzhou Medical University from January 2013 to May 2018 were retrospectively analyzed. After propensity score matching, 99 patients were enrolled, including 70 males and 29 females, aged (60.1±12.1) years. Patients were divided into the groups with thrombocytosis ( n=33) and without thrombocytosis ( n=66). The gender, maximum tumor diameter, Barcelona clinical liver cancer (BCLC) stage, and total bilirubin were compared between the two groups. The association of thrombocytosis with the prognosis of HCC after TACE treatment were analyzed using univariate and multivariate Cox regression. Results:After propensity score matching, the male proportion, maximum tumor diameter, BCLC stage, and serum level of total bilirubin were comparable between the groups (all P>0.05). Before TACE treatment, the platelet count of patients with thrombocytosis was (394.4±54.5)×10 9/L, which was higher than that after TACE [(278.2±86.4)×10 9/L, t=7.63, P<0.001]. The progression-free survival rates after TACE in without thrombocytosis group were 83.3%, 24.2%, and 7.6% at 3, 6 and 9 months, respectively, better than those in thrombocytosis group (51.5%, 3.0%, and 3.0%, respectively; χ2=31.24, P<0.001). The overall survival rates after TACE in without thrombocytosis group were 81.8%, 30.3%, and 4.5% at 1, 2 and 3 years, respectively, better than those in thrombocytosis group (15.2%, 9.1%, and 3.0%, respectively; χ2=27.89, P<0.001). Multivariate Cox regression analysis showed that patients of HCC with thrombocytosis had an increased risk of tumor progression ( HR=5.785, 95% CI: 3.291-10.168, P<0.001) and increased risk of death ( HR=4.090, 95% CI: 2.482-6.740, P<0.001) after TACE. Conclusion:The prognosis of TACE for HCC might be worse in patients with thrombocytosis. Thrombocytosis is a risk factor for cumulative survival and progression-free survival of HCC patients after TACE.

Objective:To evaluate the relationship between red blood cell distribution width (RDW) and prognosis of patients with hepatocellular carcinoma (HCC) andergoing transcatheter arterial chemoembolization (TACE).Methods:Clinical data of 212 patients with HCC andergoing TACE for the first time in Department of Interventional Radiology, the Affiliated Hospital of Xuzhou Medical University from January 2011 to May 2018 were retrospectively analyzed, including 184 males and 28 females, aged (56.8±11.2) years. Follow-up for survival. X-tile software was used to determine 13.1% as the optimal threshold for preoperative RDW prediction of prognosis, and enrolled patients were divided into a low level group (RDW<13.1%, n=70) and a high level group (RDW≥13.1%, n=142). Aspartate aminotransferase, total bilirubin, albumin, hemoglobin and lipoprotein a, Barcelona clinical liver cancer (BCLC) stage and other indexes were compared between the two groups. Survival analysis was performed by Kaplan-Meier method, survival rate was compared by log-rank test, and the effect of RDW on prognosis was analyzed by Cox regression. Results:The 1-year, 2-year and 3-year cumulative survival rates in RDW high level group were 34.5%, 14.1% and 6.3%, respectively, while those in RDW low level group were 64.3%, 38.6% and 21.4%, respectively, with significant difference ( χ2=23.09, P<0.001). Compared with the low level group, the levels of aspartate aminotransferase and total bilirubin were higher, the levels of albumin, hemoglobin and lipoprotein a were lower, the proportion of portal vein cancer thrombin was higher, and the stage of BCLC was later, with statistical significance (all P<0.05). Cox regression analysis showed that HCC patients with RDW≥13.1%( HR=1.732, 95% CI: 1.223-2.452, P=0.002) had poor survival prognosis after TACE. Conclusion:Preoperative RDW≥13.1% is an independent risk factor for survival after TACE in patients with HCC. RDW has potential predictive value for prognosis of patients with HCC.
