This study was designed to investigate the correlation between autophagy and polarization of macrophages in atherosclerosis (AS) plaque in arteriosclerosis obliterans amputees. Femoral artery specimens from arteriosclerosis obliterans amputees were performed hematoxylin and eosin (HE) staining, oil red O and immunofluorescence staining to observe the morphology of atherosclerotic plaque, phenotype of macrophages and autophagy in plaque; using real-time quantitative RT-PCR technology to detect the mRNA level of M1 and M2 type markers in arterial tissue; to analyze polarized signal pathway and autophagy protein levels in macrophages by Western blotting. Arterial specimens staining showed obvious lipid deposition and obvious infiltration of amount of foam cells and inflammatory cells. Macrophages were mainly expression M1 type in percentage in fibrous plaque. Although both M1 and M2 macrophages were upregulated in atheromatous plaque, the increase was dominant in M2 type in percentage. The level of autophagy was significantly higher in the atheromatous plaque than that of fibrous plaque. The expression of tumor necrosis factor- α (TNF-α), monocyte chemotactic protein-1 (MCP-1), inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6) and interleukin-12 (IL-12) mRNA was significantly higher in fibrous plaque than that of atheromatous plaque (P < 0.01 or 0.05), and arginase-1 (Arg-1), transforming growth factor-β (TGF-β), CD163 and interleukin-10 (IL-10) mRNA was significantly lower than that in atheromatous plaque (P < 0.01). The levels of p-STAT1 and NF-κB were significantly increased in fibrous plaque (P < 0.01), while p-STAT6 expression was significantly increased in atheromatous plaque (P < 0.01). The level of LC3-II was significantly higher in atheromatous plaque than that in fibrous plaque (P < 0.01). Macrophages in early atherosclerotic plaque were induced to M1 type through p-STAT1/NF-κB pathway and expressed moderate levels of autophagy; while macrophages in advanced plaques were induced to polarization of M2 type through p-STAT6 pathway. M2 macrophages expressed a higher level of autophagy than M1 macrophages.

Influenza virus causes serious threat to human life and health. Due to the inherent high variability of influenza virus, clinically resistant mutant strains of currently approved anti-influenza virus drugs have emerged. Therefore, it is urgent to develop antiviral drugs with new targets or mechanisms of action. RNA-dependent RNA polymerase is directly responsible for viral RNA transcription and replication, and plays key roles in the viral life cycle, which is considered an important target of anti-influenza drug design. From the point of view of medicinal chemistry, this review summarizes current advances in diverse small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase, hoping to provide valuable reference for development of novel antiviral drugs.

The present study aimed to explore whether the stretch of ischemic myocardium could modulate the electrophysiological characteristics via mechanoelectric feedback (MEF), as well as the effect of phalloidin on the electrophysiological changes. Thirty-two Wistar rats were randomly divided into 4 groups: control group (n=9), phalloidin group (n=7), myocardial infarction (MI) group (n=9), MI + phalloidin group (n=7). The acute myocardial infarction (AMI) was conducted by ligation of the left anterior descending (LAD) coronary artery for 30 min in isolated rat heart. The volume alternation of a water-filled latex balloon in the left ventricle produced the stretch of myocardium. After perfused on Langendorff, the isolated hearts were stretched for 5 s by an inflation of 0.1, 0.2 and 0.3 mL separately and the effect of stretch was observed for 30 s, including the left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), ±dp/dt(max), monophasic action potential duration at 90% repolarization (MAPD90), and occurrence of premature ventricular beats (PVB) and ventricular tachycardia (VT). The stretch caused an increase of MAPD(90) in both control and MI rats (P<0.05, P<0.01). Moreover, MAPD(90) in MI group increased more significantly than that in the control group at the same degree of stretch (P<0.05, P<0.01). Phalloidin (1 μmol/L) had no effect on MAPD(90) in basal state. After stretch, MAPD(90) in phalloidin group slightly increased but was not significantly different from that in the control group. However, phalloidin reduced MAPD(90) in infarcted myocardium, especially when ΔV=0.3 mL (P<0.05). The incidence rates of PVB and VT in MI group were higher than that in the control group (both P<0.01). And there was no significant difference in the incidence rates of PVB and VT between phalloidin group and control group. Phalloidin inhibited the occurrence of PVB and VT in infarcted hearts (both P<0.01). LVSP and +dp/dt(max) in MI group obviously decreased (P<0.01 vs control). With application of phalloidin, LVSP slightly, but not significantly increased in infarcted hearts, while -dp/dt(max) significantly increased (P<0.05). It is suggested that MI facilitates the generation and maintenance of malignant arrhythmias, while phalloidin obviously inhibits the occurrence of arrhythmias.

Objective To evaluate the application of 43-plex SNP typing system in forensic science. Methods The typing of 43 SNP loci in 123 unrelated Han individuals from East China was detected by MALDI-TOF-MS. The application value of 43-plex SNP typing system was assessed according to the foren-sic parameters of population genetics. Results All the 43 SNP loci of 123 individuals showed no signifi-cant departure from Hardy-Weinberg equilibrium (P>0.05). Excepted rs1355366, rs2270529, rs10776839 and rs938283, there were 39 SNP loci had minor allele frequencies (MAF), which were greater than 0.25. Among the 25 loci MAFs, 24 ranged from 0.4 to 0.5, while 3 were close to 0.4. The DP, CDP, PIC, Ho, PEtrio and PEduo of the 43 SNP loci were 0.2901-0.6544, 1-9.8×10-11, 0.1708-0.5000, 0.1557-0.5935, 0.0854-0.2500 and 0.0146-0.1250, respectively. The CPEtrio and CPEduo were 0.999986 and 0.9924361, respectively. Conclusion The 43-plex SNP typing system in present study shows a high polymorphism, which can be an effective supplement and verification for traditional STR genetic markers. It also can be used with other commercial kits for the forensic paternity testing and individual identification.

OBJECTIVESTo develop techniques which can be used to detect genetic material of measles virus from clinical samples to make diagnosis and differentiate atypical measles from other exanthematous infections early in clinical course.
METHODSA nested reverse transcriptase-polymerase chain reaction (RT-PCR) was developed to amplify gene fragment with the size of 301 bps from N gene of measles virus in throat swabs and urine samples collected from infants and children who were suspected measles cases. Before the test was used for clinical samples, preliminary tests were performed to determine the sensitivity and specificity of the test. The sensitivity of the test was determined by plaque assay using measles virus strain Edmonton and the specificity of the test was determined by cross-reaction with rubella virus, respiratory syncytial virus, influenza A and B viruses, enterovirus, adenovirus, human cytomegalovirus (hCMV), EB virus, and herpes simplex virus I. Serum specific IgM antibody against measles virus was also tested by ELISA.
RESULTSMeasles virus with the titer of 0.53 pfu could be detected by using the nested RT-PCR developed in this study. No amplification was found with the nested RT-PCR when rubella virus, respiratory syncytial virus, influenza A and B virus, enterovirus, adenovirus, hCMV, EB virus, and herpes simplex virus I were used as templates. Out of 116 throat swabs collected from suspected measles cases, 70 (60.3%) were measles RNA positive. For urine samples, 48 out of 74 (64.9%) were positive. Both throat swab and urine samples were collected simultaneously from 73 patients. Among those, 71 (97.3%) showed consistent results. Serum specimens were collected from 110 suspected patients. Among those, 65 (59.1%) and 61 (55.5%) were measles virus specific IgM antibody positive detected with ELISA kits from two different sources, respectively. Out of 110 sera samples, 106 (96.4%) showed consistent results. The consistency of the gene amplification and specific IgM antibody detection was 80.8% as shown by 84 out of 104 patients from whom throat swab and sera were collected at the same time.
CONCLUSIONThe data indicate that the nested RT-PCR developed in this study is sensitive and specific for detection of gene fragment of measles virus from clinical samples. The test is superior to the commonly used specific IgM antibody detection because of identifying gene material in early clinical stage, and even single clinical sample can be tested.
