Objective: This study aimed to identify internal ribosome entry sites (IRESs) in the open reading frame (ORF) of the Coxsackievirus B3 (CVB3) genome. Methods: The sequences of P1, P2, or P3 of the CVB3 genome or the truncated sequences from each antithymocyte globulin (ATG) to the end of the P1, P2, or P3 gene were inserted into the pEGFP-N1 vector. After transfection, possible IRES-dependent green fluorescent protein (GFP)-fused proteins were detected by anti-GFP western blotting. The sequences of possible IRESs were inserted into specific Fluc/Rluc bicistronic vectors, in which the potential IRESs were determined according to the Fluc/Rluc activity ratio. Expression of Fluc and Rluc mRNA of the bicistronic vector was detected by RT-qPCR. Results: After transfection of full length or truncated sequences of the P1, P2, or P3 plasmids, six GFP-fused protein bands in P1, six bands in P2 and nine bands in P3 were detected through western blotting. Two IRESs in VP2 (1461-1646 nt) and VP1 (2784-2983 nt) of P1; one IRES in 2C (4119-4564 nt) of P2; and two IRESs in 3C (5634-5834 nt) and 3D (6870-7087 nt) of P3 were identified according to Fluc/Rluc activity ratio. The cryptic promoter was also excluded by RT-qPCR. Conclusion Five IRESs are present in the CVB3 coding region.

Objective To study the characteristics of hyperphenylalaninemia (HPA) and the differences in blood and urine metabolic index and their correlation.Methods A total of 137 patients with HPA diagnosed by the Pediatric Inherit Metabolism and Endocrine Department,Guangdong Women and Children's Hospital,Guangzhou Medical University from January 2014 to June 2017,were enrolled.Tandem mass spectrometry (MS/MS),gas chromatography/ mass spectrometry (GC-MS) and high performance liquid chromatography (HPLC) were used to analyze the concentration of blood and urine metabolites in children,and the patients were divided into different groups according to the drug load test of tetrahydrobiopterin (BH4) and dihydrobiopterindine reductase (DHPR) deficiency.The HPA metabolite analysis of horizontal concentration by statistical differences and correlation analysis were performed.Results Among the 137 cases of HPA,there were 101 cases (73.7％) of phenylalanine hydroxylase deficiency (PAH),and among them 21 cases (15.3％) were classic phenylketonuria (PKU),37 cases were mild PKU (27.0％),43 cases (31.4％) wcrc mild HPA.Thcrc were 22 cases (16.1％) with BH4 reaction,and 79 cases (57.7％) of non-reactive type.Besides,there were 36 cases (26.3％) of tetrahydrobiopterin deficiency (BH4 D),of which 6-pyruvoyl tetrahydropterin synthase deficiency (PTPS) in 34 cases (24.8％) and dihydrobiopterindine reductase deficiency (DHPR) in 2 cases (1.5％).Urinary phenylacetic acid (r =0.673,P ＜ 0.01),phenyllactic acid (r =0.736,P ＜ 0.01),phenylpyruvic acid (r =0.642,P ＜ 0.01) were significantly correlated with blood phenylalanine (Phe) concentration,and the neopterin (N) (r =0.442,P ＜ 0.01) and biopterin (B) (r =0.398,P ＜ 0.01) had low correlation.Urinary phenylacetic acid,phenyllactic acid and phenylpyruvic acid had no correlation with urinary pterin.There were significant differences among PTPS deficiency group,BH4 response type,and non-reactive type(all P ＜ 0.05),but no significant difference between the BH4 reaction type and the non-reactive group (P ＞ 0.05).Conclusions Through the analysis of the different types of HPA metabolic profiles,it can help to master the incidence and characteristics in the region,within a certain concentration range of blood Phe,the phenylacetic acid,phenyllactic acid,phenylpyruvic acid should not be tested by GC-MS alone.Uterine erythropoietin analysis of BH4D classification and identification of BH4 reaction,non-reactive PKU have a supporting role,so master the metabolic index of various types of concentration and relevance of HPA,it can provide basis for early diagnosis,accurate treatment and follow-up.

AIM:To investigate the angiogenic effect and mechanisms of astragaloside IV(AS-IV)in rats with myocardial infarction via protein kinase D 1(PKD1)-histone deacetylase 5(HDAC5)-vascular endothelial growth factor (VEGF)signaling pathway.METHODS:The classic model of myocardial infarction by ligation of the left anterior de-scending coronary artery was replicated,and the rats were randomly divided into model group,AS-IV group,and AS-IV+CID755673(PKD1 inhibitor)group.The sham operation control group and DMSO control group were also set up.All the rats were given intravenous injection via caudal vein.The rats were sacrificed 4 weeks later,and segmental heart samples were used for HE staining and Masson staining.The expression of PKD1,HDAC5 and VEGF was analyzed by immunohis-tochemistry,RT-PCR and and Western blot.RESULTS:Compared with sham operation group and DMSO group,the myo-cardium in model group showed disordered arrangement, accompanied with necrotic myocardial cells and obvious fibrosis tissue.After treatment with AS-IV,the morphological changes of myocardium were obviously improved,and the number of new blood vessels increased significantly.However,after treatment with AS-IV+CID755673,the myocardial tissues of the rats became disordered again,with increased necrotic cells and some closed vessels.The mRNA and protein expression of PKD1,HDAC5 and VEGF in myocardial tissue in model group was significantly lower than that in sham operation and DMSO groups(P<0.05).The expression in AS-IV group was significantly higher than that in model group(P<0.01), while that in AS-IV+CID755673 group was significantly lower than that in AS-IV group(P<0.05).CONCLUSION:AS-IV promotes the angiogenesis of myocardial tissues in the rats after myocardial infarction partly by regulating the PKD 1-HDAC5-VEGF signaling pathway.

OBJECTIVE This study aimed to investigate the role and mechanism of Astragaloside IV (AS-IV)in rats with myocardial infarction.METHODS The myocardial infarction model was established by ligation of the left anterior descending artery. The rats were randomly divided into sham, DMSO, model group, AS-IV and CID755673 groups. The rats were sacrificed 4 weeks later, and segmental heart samples were used for hematoxylin and eosin staining and masson staining. The expression of PKD1, HDAC5 and VEGF were analyzed using immunohistochemistry, reverse transcription poly-merase chain reaction and western blot. RESULTS Compared with the sham operation and DMSO groups,morphology of myocardium in model group was disordered,accompanied with necrotic myocar-dial cells and obvious collagen tissues. After treatment with AS-IV, the morphology of myocardium was obviously improved, and the number of new blood vessels increased significantly. However, after treatment with CID755673, the myocardial tissue of rats became disordered again, the necrotic cells increased, and some vessels closed. The expression levels of PKD1, HDAC5 and VEGF mRNA and protein in myocardial tissue of model group were significantly lower than the other four groups(P<0.05), whereas these levels in the AS-IV group were significantly higher than those in the other four groups (P<0.01). Additionally, the CID755673 group had significantly higher levels of PKD1, HDAC5 and VEGF mRNA and protein than the sham group, DMSO group and model group (P<0.05). CONCLUSION AS-IV may partly promote the angiogenesis of myocardial tissue in rats with myocardial infarction via the PKD1-HDAC5-VEGF pathway.

Objective To explore the effect of astragalus extracts on adherence, migration, cell viability, microvascular formation, and eNOS expression in bone marrow-derived endothelial progenitor cells (EPCs) of rats. Methods EPCs were cultured, isolated and identified in vitro and divided into four groups: low titer group (10-4 g/L of astragalus extracts), middle titer group (10-3 g/L of astragalus extracts), high titer group (10-2 g/L of astragalus extracts) and control group. The effects of astragalus extract on adhesion, migration or microvascular formation were observed under the inverted microscope and com?pared between all groups;Cell viability was detected by MTT assay;mRNA transcription and protein expression levels of en?dothelial nitric oxide synthase (eNOS) in EPCs were detected by reverse transcription PCR (RT-PCR) and Western blot re?spectively. Results Compared with the control group, cell adhesion, migration and microvascular formation of EPCs all en?hanced with addition of astragalus extracts in a dose dependent manner (F=15.256, 13.633, 97.549 respectively, and P <0.05 in all cases); Cell vitality of EPCs increased with administration of astragalus extracts in a time and dose dependant manner. (F=9.755 for time and F=10.18 for dose). mRNA transcription and protein expression of eNOS in EPCs were up-reg?ulated with addition of astragalus extracts in a dose dependent manner (F=56.356 and 77.125 respectively, and P<0.05 in both cases). Conclusion Astragalus extracts play important role in angiogenesis in EPCs probably through up-regulating expressions of eNOS.
