Multiple etiological factors are integrally involved in the development of hepatitis B virus (HBV)infection.Interleukin-10 (IL-10)is an essential cytokine of immune regulation,and IL-10 gene promoter polymorphism affects its mRNA transcription and serum level. IL-10 is related to the prognosis of HBV infection.This review briefly discusses the association of IL-10 gene polymorphism and its serum level with the prognosis of HBV infection,and summarizes the role of IL-10,as an anti-inflammatory cytokine,in host immune function, the prognosis and progression of HBV infection,and HBV-related complications.IL-10 gene polymorphism and its serum level are closely associated with inflammatory response after HBV infection,influence HBV clearance,and are related to the severity of HBV-related liver injury,liver cirrhosis,and hepatocellular carcinoma.The determination of IL-10 gene and serum levels may provide a predictive marker for the prognosis of HBV infection.

Neonatal pain is a common phenomenon. For a long time neonatal pain had not been focus on properly and managed appropriately. American Academy of Pediatrics Committee on Fetus and Newborn and Section on Anesthesiology and Pain Medicine published policy statement to emphasize the necessity of neonatal pain assessment,and summarize the neonatal operability pain assessment method,drug and non-drug control measures,also update prevention and management of procedural pain in the neonate in 2016. Until today the guideline for neonatal pain management has not yet been released in China. As the reference for clinicians in domestic,the content of policy statement will be reorganized and introduced.

OBJECTIVE To investigate the delayed cytotoxicity effect of chlorpyrifos (CPF) with?drawal on primary hippocampal neurons. METHODS Hippocampal neurons were prepared from SD rat fetuses on the 17th day of gestation. Seven days after culture,neurons were exposed to CPF 10 and 30 μmol · L-1,respectively,for 72 h or for 48 h followed by CPF withdrawal for 24 h. CCK-8 kit and neuronal nuclei(NeuN), 5-bromodeoxyuridine(BrdU) and β Ⅲ tubulin immunofluorescence expression methods were used to evaluate the cell viability. RESULTS Compared with normal control, no significant cytotoxicity was found after CPF 72 h continuous exposure. However,CPF 48 h expo?sure followed by CPF withdrawal for 24 h induced evident cytotoxicity. The amount of BrdU positive and β Ⅲ tubulin positive hippocampal neurons were both decreased significantly(P<0.05),and cell survival and viability reduced after CPF withdrawal. CONCLUSION CPF exposure withdrawal can induce more seriously delayed cytotoxicity than continuous exposure in rat primary hippocampal neurons.

Blood transfusion therapy is one of the commonly used intervention in newborn infants.Red blood cell transfusion is the only treatment for most cases of neonatal anemia,but the indications of application and implementation strategy are not yet perfect,and the benefits,adverse outcomes and potential risk of transfusion remains to be evaluated.There are many uncertain problems in transfusion management.This paper mainly introduces the evidence-based recommendations of neonatal blood transfusion released by Italian Society of Transfusion Medicine and Immunohaematology and Italian Society of Neonatology Working Group for reference of domestic clinicians.

As a widely accepted and convenient method,the Apgar score has been applied to assess the status of the newborn infants and the response to resuscitation since 1952.But the Apgar score has also been used inappropriately in infants to predict specific neurologic outcomes in many cases.The Apgar Score produced by American Academy of Pediatrics(AAP) in collaboration with American College of Obstetricians and Gynecologists(ACOG),updated policy statements of the Apgar score in October 2015.The Apgar score has limitations,and it is not appropriate to use it alone to establish the diagnosis of asphyxia;the method does not predict individual neonatal mortality or neurologic outcome.AAP/ACOG encourages the use of an expanded Apgar score reporting form that accounts for concurrent resuscitation interventions.

Measles is an acute viral disease, almost all deaths cases of measles in children occur in developing countries each year.Despite the availability of a safe and effective vaccine, measles is still one of the main causes of death of children in global area.2015 report of Committee on Infectious Diseases of American provided evidence of clinical diagnosis, treatment and prevention of measles.

Neonatal hypoxic-ischemic encephalopathy as a standard term has been used for over 30 years,but now increasingly being questioned.Most experts recommend using neonatal encephalopathy instead of hypoxic-ischemic encephalopathy.The American College of Obstetricians and Gynecologists and The American Academy of Pediatrics published separately the report of Task Force on Neonatal Encephalopathy Neonatal Encephalopathy and Neurologic Outcome,Second Edition in 2014.Definition,diagnosis and treatment of neonatal encephalopathy and other content have been updated in the report.It is recommended that a comprehensive multidimensional assessment be performed of neonatal encephalopathy.This article will introduce the controversy about neonatal encephalopathy or hypoxic-ischemic encephalopathy and contents of the report of Task Force on Neonatal Encephalopathy.

Bronchiolitis is a common lower respiratory tract viral infection in infants.Incidence of bronchiolitis is greatly increasing in recent years,and seriously affecting the health of children.In order to better manage bronchiolitis,American Academy of Pediatrics (AAP) convened a new subcommittee to review and revise the 2006 bronchiolitis guideline.This evidence-based guideline amended to provide new evidence of diagnosis,treatment and prevention bronchiolitis for the clinician.

Objective To assess the effectiveness and safety of Azithromycin for preventing bronchopulmonary dysplasia(BPD) in preterm infants in order to provide reference for the clinical treatment of BPD.Methods The electronic retrieval were conducted to review randomized controlled trials (RCTs) from The Cochrane Library,PubMed,EM-Base,China Biological Medicine Database (CBM),Chinese Journals full-text Database (CNKI),Chinese Technological Journals Database(VIP) and Wan Fang Digital Journal Full-text Database by free texts and medical subject headings.The retrieval time was from inception to Dec.2012.Randomized or quasi-randomized studies were conducted by comparing Azithromycin therapy and no treatment or placebo management to prevent BPD among the preterm or low birth weight infants were included.The reference lists of relevant trials and conference proceedings were searched.Risk biases of the trials were assessed.Statistical analysis was performed by using Revman 5.1 offered by Cochrane.Results A total of 2 trials including 328 preterm infants were included.No significant difference was observed between the Azithromycin group and the control group in the incidence of BPD(RR =0.81,95％ CI 0.55-1.19).The risk ratio of death and post-natal steroid used in the Azithromycin group were lower,but there was no difference.The risk ratio of length of stay was not significantly different.The rate of BPD in preterm infants who had a positive respiratory culture of Ureaplasma between the preventative Azithromycin group and the placebo group showed that the incidence of BPD was significantly less in the Azithromycin group.Conclusions The available data are insufficient to make a recommendation regarding treatment with prophylactic Azithromycin to prevent BPD in preterm infants.More RCTs with large-scale and high-quality are required to provide more reliable evidence.

Objective To study the application of a new magnetic beads made in China in DNA extraction of forensic biological samples with automation workstation.Methods DNA was extracted from common forensic biological samples by QIAGEN Bio-Robert Universal System and a new magnetic beads made in China,and then typed with Identifiler system in ABI3130XL Genetic Analyzer.210 of these samples were also quantitated by ABI7500 Real Time System.Results Total of 9100 genomic DNA was extracted from various forensic biological samples by the new magnetic beads made in China and automation workstation methods,and most of them were successfully typed for STR analysis.In these biological samples,oral swabs and muscles were of the highest Success rate of STR typing(100%),and the lowest was touched cell samples (50.0%).Conclusion The new magnetic beads made in China with automation workstation methods can be applied to DNA extraction of most forensic biological samples.
