Duchene muscular dystrophy (DMD) is a serious progressive muscular dystrophy.Reports in recent years about abnormal lipid in DMD patients have increased, yet little attention has been paid to liver lipid.This study aimed to explore the effect of dystrophin gene defect on liver lipid synthesis.7-week-old mdx male mice were used as DMD model.The conditions of liver function, liver lipid accumulation and liver lipid synthesis were determined through liver tissue morphological examination, blood biochemical examination, and detection of hepatic gene and protein expression.The results showed that lipid droplets in liver of mdx mice increased significantly.The contents of total cholesterol and triglyceride in liver, aspartate aminotransferase and alanine aminotransferase in serum increased.The gene and protein expression of hepatic lipid synthesis-related enzymes such as fatty acid synthase, acetyl CoA carboxylase, and sterol regulatory element binding protein 1-c were up-regulated.These results showed accumulation of liver lipid in 7-week-old mdx male mice.

Objective: To understand the epidemiological and etiological characteristics of enterovirus (EV)-associated diseases among children in Beijing from 2010 to 2016. Methods: This was a repeated cross-sectional study. The throat swabs were collected from children with probable EV-associated diseases at the Children' s Hospital Affiliated to Capital Institute of Pediatrics from 2010 to 2016. The samples were sent for pan-EV, enterovirus 71 (EV-A71) and coxsackievirus A16 (CV-A16) detection by real-time fluorescence reverse transcription polymerase chain reaction (RT-PCR) . The viral types of non-EV-A71 and non-CV-A16 EV-positive samples were identified using modified RT-PCR and sequencing with CV-A6, EV-A/B group and 5 'UTR universal primers. The constituent ratios of the prevalence of different EV types in different age and gender groups were compared. Results: Of the 2 703 throat swabs, 1 992 (73.7%) samples were positive for EV, including EV-A71 (19.1%, 516/2 703), CV-A16 (24.3%, 658/2 703), CV-A6 (22.2%, 600/2 703), CV-A10 (4.5%, 122/2 703) and other types of EV (3.5%, 95/2 703). There was 1 case of EV-A71 and CV-A16 co-infection. The positive detection rate of EV-A group (excluding EV-A71, CV-A16, CV-A6 and CV-A10) increased from 11.3% (7/62) to 95.2% (59/62) after using the modified VP1-specific primers and PCR amplification conditions. During the period between 2010 and 2012, CV-A16 and EV-A71 predominated in EV-positive samples. However, CV-A6 accounted for 60.7% (68/112) in 2013, much higher than CV-A16 (23.2%, 26/112) and EV-A71 (12.5%, 14/112). In 2014, EVs were mainly of CV-A16 and EV-A71, but CV-A6 was the predominant type in 2015 (68.2%, 232/340) and in 2016 (38.6%, 151/391). The epidemic season of EVs was mostly from April to August, but CV-A6 showed a small epidemic peak from October to November. The male-to-female ratio of EV-positive patients was 1.50∶1, and EV-associated diseases mostly occurred in children under 5 years of age. Younger children were more susceptible to CV-A6 than to EV-A71 and CV-A16. Conclusions From 2010 to 2016, there was a significant change in the spectrum of EVs in children with EV-associated diseases in Beijing. Since 2013, non-EV-A71 and non-CV-A16 increased, and CV-A6 gradually became one of the major pathogens of EV-associated diseases. The modified PCR primers and amplification conditions can effectively improve the reliability of test results.

RESULTSOf 270 cases from three groups of ARI patients, including Out-patients, In-patients and patients in the intensive care unit (ICU), viruses were detected in 176 (65.2%) specimens with the RVP Fast assay. The viral detection rate from the Out-patients group (50.0%) was significantly lower than that from the In-patients (71.1%) and ICU-patients (74.4%) groups. The virus distribution was different between the Out-patients group and the other hospitalized groups, while the virus detection rate and distribution characteristics were similar between the In-patients and ICU-patients groups. The co-infection rates of the Out-patients group, the In-patients group, and the ICU-patients group were 15.6%, 50.0% and 35.8%, respectively. In addition to respiratory syncytial virus (RSV) and adenovirus (ADV), human rhinovirus (HRV) was frequently detected from children with serious illnesses, followed by human metapneumovirus (hMPV), human bocavirus (HBoV) and coronaviruses. Parainfluenza virus 3 (PIV3) was detected in children with lower respiratory illness, but rarely from those with serious illnesses in the ICU-patient group.

CONCLUSIONIn addition to so-called common respiratory viruses, virus detection in children with ARI should include those thought to be uncommon respiratory viruses, especially when there are severe ARI-related clinical illnesses.

OBJECTIVEHuman parechovirus (HPeV) is a single-stranded, positive sense RNA virus in the Parechovirus genus within the large family of Picornaviridae. As a possible new pathogen of neonatal sepsis, meningoencephalitis and other infections in young children, HPeV gets more and more attention. This study aimed to better understand the association of HPeV with central nervous system (CNS) infectious diseases and sepsis among hospitalized children in Beijing.

METHODA total of 577 cerebrospinal fluid (CSF) samples were retrospectively collected from 557 children suspected of CNS infections in 2012. Three hundred and fifty-one of them were male and 206 were female. HPeV was screened by reverse transcription-nested PCR (RT-nPCR) with the universal primers which target the highly conserved 5'UTR. The positive samples were genotyped by amplifying and sequencing for the VP3/VP1 junction region. The sequences were compared with the HPeV sequences from GenBank and performed phylogenetic analysis.Some samples other than CSF from HPeV positive children, including serum, nasopharyngeal aspirate and stool, were collected and carried out screening for HPeV.

RESULTWith the RT-nPCR by universal primers, HPeVs were detected in 18 out of 577 CSF samples obtained from 18 children with a positive rate of 3.1%. The ratio of male and female was 2: 1. There were no statistically significant differences on infection rate between boys (12/351, 3.4%) and girls (6/206, 2.9%). All of 18 positive CSF samples were negative for enterovirus, Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), and herpes simplex virus 1 and 2 (HSV).HPeVs from 10 positive CSF samples were genotyped successfully, consisting of 7 HPeV3 and 3 HPeV1. In addition, 2 of 8 serum samples were positive for HPeV3 and 1 of 2 stool samples were positive for HPeV 1. HPeVs were identified in CSF from children aged from 15 days to 14 years, in which 7 cases were infants younger than 3 months and 5 cases were infants from 3 months to one year. Three children older than the age of 9 years (9, 13 and 14 years) were positive for HPeV. Most of the children (6/8) infected with HPeV3 were younger than 3 months and were diagnosed as sepsis, while the rest of HPeV3 positive children were diagnosed as meningitis and bronchopneumonia. HPeV3 infection clustered in August, while HPeV1 in January.

CONCLUSIONHPeVs were associated with CNS infections and sepsis in hospitalized children in Beijing, especially in children younger than one year.HPeV3 was the predominant type identified in CSF.
