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.

ObjectiveToinvestigateRUNX3genepromoter methylationincolorectal carcinogenesis and its prognostic significance. MethodsThe protein expression of RUNX3 was detected by immunohistochemistry and the methylation status of the RUNX3 was determined by methylation-specific PCR (MSP) in colorectal normal mucosa and cancer tissue from 65 patients,and adenoma from 28 patients.5-year overall survival rate was analysed according to RUNX3 methylation status from cancer patients.Kruskal-Wallis rank sum test,x2 or Fisher's exact test,Log-rank test and multivariable Cox regression analysis were used for statistical analysis.ResultsThe protein expression of RUNX3 gene in adenoma and cancer was 85% (24/28) and 52% (34/65),significantly lower than that in normal mucosa 94% (61/65)( x2 =4.328,P =0.037 ; x2 =16.675,P =0.000),the difference between adenoma and cancer tissue was no statistic significance (x2 =3.266,P =0.071 ).No case showed RUNX3 methylation in normal mucosa,methylation rates in adenoma and cancer tissue were 21% (6/28) and 35% (23/65),significantly higher than in normal mucosa (P =0.000 ),but there was no statistic significance between adenoma and cancer tissue (x2 =1.766,P =0.183).The protein expression rate with RUNX3 methylation was 67% (4/6) in adenoma,unmethylation 91% (20/22) (P =0.191 ).The protein expression rate with RUNX3 methylation was 26% (6/23) in cancer,unmethylation was 88% (28/32).The presence of RUNX3 methylation was related to loss of protein ( x2 =9.810,P =0.002 ).5-year total survival rate with methylation in cancer was significantly lower with unmethylation ( x2 =5.87,P =0.016 ).Multivariate analysis showed RUNX3 methylayion wasanindependentprognosticfactoramongthefactorsanalyzed(P=0.033 ).ConclusionsRUNX3 methylation is important genetic event in colorectal carcinogenesis,possibly related to protein downregulation,and an independent prognostic factor for colorectal carcinoma.

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.
