ABSTRACT

Objective To investigate the differences in expression profile of long non-coding RNA (lncRNA) in retina between normal newborn mice and those with oxygen-induced retinopathy (OIR) to lay a foundation for further study of regulatory mechanisms of lncRNA in retinal neovascularization, and to provide a new theoretical basis for the prevention and treatment of retinopathy of prematurity (ROP). Methods A total of 48 cleaning grade C57BL/6J neonatal mice were randomly divided into two groups with 24 in each: OIR group and control group. Those in the OIR group were exposed to hyperoxia [(75±2)% O2] from 7th to 12th day after birth, and then re-exposed to normoxia (room air) for five days to establish a OIR mouse model. Mice in the control group were raised in room air all the time. Retinal tissues were collected from each mouse on the 17th day after birth. Retinal angiography and hematoxylin-eosin (HE) staining were performed to confirm the establishment of OIR mouse model. Expression profiles of lncRNAs were analyzed by lncRNA high-throughput sequencing and the results were verified by real-time fluorescence quantitative polymerase chain reaction (PCR). Based on the expression of lncRNAs and mRNA and the relationship between their genomic locations, potential target genes of lncRNAs were obtained. Gene ontology analysis (GO) and Kyoto Encyclopedia of Genes and Gnomes (KEGG) pathway analysis were used for bioinformatics analysis of lncRNA expression profile in OIR. T test and Graphpad prism were used for statistical analysis and spreadsheet. Results Retinal angiography and HE staining identified serious retinal damage in the OIR group. In total, 1118 differentially expressed lncRNAs ( ≥ 2.0-fold difference in expression, P<0.05) relating to OIR between the two groups were identified by lncRNA high-throughput sequencing. Results of real-time fluorescence quantitative PCR confirmed that XLOC_150632 and XLOC_150636 were upregulated in the OIR group as compared with those in the control, while XLOC_122045,XLOC_100454, XLOC_170009 and XLOC_122042 were downregulated. GO analysis showed that 852, 1148 and 2100 target genes of differentially expressed lncRNAs were relating to biological process, cellular component and molecular function, respectively. KEGG analysis showed that the target genes were associated with 36 biological pathways, mainly relating to retinal development, chemotaxis, migration and energy metabolism of vascular endothelial cells. Conclusions lncRNAs are differentially expressed in healthy newborn mice and newborn mice with OIR. Fibroblast growth factor 2 (FGF2), the potential target gene of XLOC_150632 and XLOC_150636, is related to phosphatidylinositol-3-kinase (PI3K) signaling pathway and may be involved in retinal neovascularization. This might be a potential target for ROP prevention and treatment.

ABSTRACT

Innate immune cells have a critical role in defense against infections and diseases.Central to this is the broad specificity with which they can detect pathogen-associated patterns and danger-associated patterns via the pattern recognition receptors (PRRs) they express.TLR is one of the most largely studied families of PRRs.Activation of TLR promotes both innate inflammatory responses and the induction of adaptive immunity.Given the characteristics of TLR,various Toll like receptor agonists are used in vaccine design to accelerate the immune response and produce long-lasting protection.

ABSTRACT

Radial-cephalic arteriovenous fistula (RCAVF) is considered the first choice for hemodialysis vascular access because of its high patency rate and less complications.But up to 50% of the fistula can not mature.This is mainly due to persistent low blood flow or difficulty in cannulation can not lead to adequate hemodialysis.Inflow or outflow stenosis,anastomotic stenosis,exceedingly deep location of the vein,flow diversion into accessory veins are the common causes of impaired maturation.In addition,thrombosis is a common of stenosis.Preoperative assessment by physical examination and ultrasound examination of blood vessels,select the appropriate blood vessels for the fistula is of great significance.Choose the appropriate treatment for the cause of maturation disorders.Postoperative aspirin is widely used to prevent thrombosis and reduce the occurrence of stenosis;Surgery has the advantage of bypassing the damaged area but creating a new stoma;in recent years,endovascular technique because of its characteristics of minimally invasive in most of the time is the first choice.In this paper,the definition,etiology,diagnosis and treatment of fistula maturation disorder are reviewed.

ABSTRACT

Objective@#To investigate the effect of nicorandil on ventricular arrhythmia in patients with acute ST-segment elevation myocardial infarction (STEMI) treated with emergent percutaneous coronary intervention (PCI).@*Methods@#A total of 120 acute STEMI patients treated with emergent PCI in our hospital from January 2015 to June 2016 were randomly divided into control group and experiment group (n=60 each). Patients in both groups received conventional therapy.Patients in experiment group took 10 mg nicorandil orally before PCI and received oral nicorandil treatment (15 mg/d, three times daily) for 3 days.QT disperse(QTd), correct QTd(QTcd) and the occurrence rate of ventricular arrhythmia were compared between two groups.@*Results@#QTd at 6, 24, 48 and 72 hours((70.6±4.4), (67.2±5.3), (55.7±8.5), (48.2±8.2) ms, respectively) after PCI was significantly lower in the experiment group than those of control group ((77.1±7.1), (71.3±6.5), (65.1±8.1), (57.2±5.4) ms, all P<0.05). The level of QTd was also significantly lower in the experiment group at 6, 24, 48 and 72 hours((77.5±7.7), (67.7±8.6), (61.2±7.5), (52.9±8.4) ms, respectively) after PCI comared to those of control group ((88.6±8.1), (79.2±7.8), (74.4±7.4), (69.6±8.6) ms, all P<0.05). There was no significant difference in the incidence of reperfusion arrhythmia during PCI procedure between the two groups.The prevalence of the ventricular premature beat in the experiment group (25/60, 41.7%) was significantly lower than in the control group(45/60, 75.0%) within 3 days after PCI(P<0.01), the prevalence of the no sustained ventricular tachycardia and ventricular fibrillation in the experiment group(6/60, 10.0%) was also significantly lower than in the control group (18/60, 30.0%, P<0.01) within 3 days after PCI.@*Conclusions@#Nicorandil use prior and post PCI could decrease the occurrence rate of ventricular arrhythmia in STEMI patients undergoing emergent PCI, and this effect might be related with reduced QTd and QTcd post medication.

ABSTRACT

Objective To prepare a neutralizing monoclonal antibody against rabies virus. Meth-ods BALB/c mice were immunized with the inactivated rabies virus CTN strains on day 0, 7, 14 and 28. Spleen cell samples were collected and then fused with SP2/0 cells to prepare the hybridoma cell line. Posi-tive hybridoma cells that were screened out with RFFIT technique were injected into BALB/c mice intraper-itoneally. Ascites samples were collected from the mice to separate neutralizing monoclonal antibodies. Affin-ity chromatography was used for the purification of neutralizing monoclonal antibodies. Subtype identification and sequencing analysis were performed for further identification. A colloidal gold strip based method for rap-id detection of rabies vaccine was established with the prepared monoclonal antibodies. Results The hybri-doma cell line, CTN-McAb1, was prepared successfully with stable secretion of neutralizing monoclonal anti-bodies against rabies virus. The purity of those antibodies was more than 95% after purification and the sub-type of them was IgG1. The colloidal gold strip for raid detection of rabies vaccine was successful prepared. Conclusion The neutralizing monoclonal antibody against rabies virus was successfully prepared and could be used for preliminary application. This study will be of great significance for the quality control of rabies vaccine.

ABSTRACT

Objective: To investigate the relationship between blood lipid proifles and intraocular pressure (IOP) in adult subjects. Methods: A total of 1660 adult subjects received regular physical examination in our hospital from 2015-01 to 2015-09 were enrolled. The subjects were divided into 2 groups: Hyperlipidemia group,n=356 and Non-hyperlipidemia group,n=1304. Systolic, diastolic blood pressure (SBP), (DBP), IOP and serum levels of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1(ApoA1) and apolipoprotein B (ApoB) levels were measured in all subjects. SPSS19.0 software was used to study the relationship between blood lipid proifles and IOP by univariate and multivariate liner regression analysis respectively. Results: Univariate regression analysis revealed that IOP was positively related to SBP, DBP, TC, TG, LDL-C and ApoB, all P<0.05, while negatively related to HDL-C,P=0.028. Multivariate regression analysis indicated that with adjusted age, SBP and DBP, IOP was positively related to TC, TG, LDL-C, ApoA1 and ApoB, while negatively related to HDL-C, allP<0.05. ApoB level in either Hyperlipidemia group or Non-hyperlipidemia group was signiifcantly related to IOP in both male and female genders,P<0.05. Conclusion: ApoB level was most obviously related to IOP and it might be used as a predictor for IOP elevation in clinical research, while its validity should be further studied.

ABSTRACT

Ebola virus (EBOV) and Marburg virus (MARV) are causative agents of severe hemorrhagic fever with high mortality rates in humans and non-human primates and there is currently no licensed vaccine or therapeutics.To date,there is no specific laboratory diagnostic test in China,while there is a national need to provide differential diagnosis during outbreaks and for instituting acceptable quarantine procedures.In this study,the TaqMan RT-PCR assays targeting the nucleoprotein genes of the Zaire Ebolavirus (ZEBOV) and MARV were developed and their sensitivities and specificities were investigated.Our results indicated that the assays were able to make reliable diagnosis over a wide range of virus copies from 103 to 109,corresponding to the threshold of a standard RNA transcript.The results showed that there were about 1010 RNA copies per milliliter of virus culture supernatant,equivalent to 10,000 RNA molecules per infectious virion,suggesting the presence of many non-infectious particles.These data indicated that the TaqMan RT-PCR assays developed in this study will be suitable for future surveillance and specific diagnosis of ZEBOV and MARV in China.

ABSTRACT

Ebola virus(EBOV)and Marburg virus(MARV),belonging to the Filoviridae family,emerged four decades ago and caused severe viral hemorrhagic fever in human and other primates.As high as 50-90% mortality,filoviruses can cause significant threats to public health.However,so far no specific and efficient vaccine has been available,nor have other treatment methods proved to be effective.It is of great importance to detect these pathogens specific,rapidly and sensitively in order to control future filovirus outbreaks.Here,recent progresses in the development of detection and diagnosis methods for EBOV and MARV are summarized.
