MicroRNA(miR)-203 is a stemness-inhibiting miRNA that adjusts the epithelioid cell differentiation by restricting the expression of stemness-related transcription factor.Its abnormal expression has been detected in several types of human cancers,including bladder cancer,breast cancer,colon cancer and pancreatic cancer.miR-203 plays a critical role in the tumor genesis and development by regulating cell proliferation,differentiation and apoptosis.

Objective To explore the prognostic factors of middle and advanced esophageal neoplasms treated by traditional Chinese medicine combined with radiotherapy.Methods A total of 462 esophageal neoplasms patients treated by traditional Chinese medicine combined with radiotherapy from March 2009 to March 2012 in Civil Administration Hospital of Hebei Province were retrospectively analyzed.The overall median survival time and the survival rate of 1,3 and 5 years were calculated by using life table.Log-rank test was used for single-factor analysis and Cox model was used for multiple-factor analysis.Results The median survival time of 462 esophageal neoplasm patients was 24.2 months (12.9-36.6 months).The survival rate of 1,3 and 5 years was 80.3 ％,30.6 ％ and 10.5 ％ respectively.Single-factor analysis showed that the age (x2 =89.773,P =0.000),tumor diameter (x2 =102.373,P =0.000),clinical staging (x2 =128.903,P =0.000),concomitant with other diseases (x2 =65.366,P =0.000) and the short term effect (x2 =64.948,P =0.000) were associated with prognosis of middle and advanced esophageal neoplasms treated by traditional Chinese medicine combined with radiotherapy.Multiple-factor analysis showed that the age (RR =1.625,95 ％ CI 1.251-2.111,P=0.000),clinical staging (RR =2.437,95 ％ CI 1.874-3.168,P=0.000),concomitant with other diseases (RR =1.1.628,95 ％ CI 1.278-2.076,P =0.000) and the short term effect(RR =1.865,95 ％ CI 1.594-2.182,P =0.000) were the independent prognosis factors for middle and advanced esophageal neoplasms treated by traditional Chinese medicine combined with radiotherapy.Conclusion Elderly patients,esophageal neoplasms in stage Ⅲ,concomitant with other diseases and poor short-term effect could influence the prognosis of the patients with middle and advanced esophageal neoplasms treated by traditional Chinese medicine combined with radiotherapy.

Objective To explore the risk factors of central neck lymph node metastases in clinically node-negative (cN0) papillary thyroid carcinoma (PTC) and the rationality of prophylactic central neck dissection. Methods The clinical data of 1359 patients who had underwent PTC treatment at the Department of Head and Neck Surgery , Henan Provincial Cancer Hospital during the five years (from 2011-01 to 2015-12) were analyzed retrospectively. Results There were 376 patients (27.67％, 376/1359) with central neck lymph node metastases. Single factor analysis and multivariate Logistic regression analysis showed that the central neck lymph node metastases were related to tumor max diameter≥10 mm, extrathyroidal extension (P<0.01), age<55 years old (P<0.01), multifocality (P<0.01), and PTC located at the isthmus (P<0.01). Conclusions Risk stratification should be performed on cN0 PTC. Prophylactic central neck dissection should be performed in cN0 patients with the tumor max diameter ≥ 10 mm, capsule invasion, age <55 years, multiple tumors, isthmus PTC and Hashimoto thyroiditis patients.

OBJECTIVETo investigate the germline mutations of the CHD7 gene and their roles in patients with congenital heart disease (CHD).

METHODSGenomic DNAs extracted from peripheral blood were subjected to screen mutations in CHD7 gene by denaturing high performance liquid chromatography (DHPLC) followed by DNA sequencing of aberrant peaks in 67 CHD patients and 100 healthy control. Case-control study and bioinformatic analysis were utilized to explore the potential functional roles of the variations detected.

RESULTSSeven kinds of single nucleotide substitution were detected in the CHD patients in different introns of the CHD7 gene. Among them, IVS11+ 127A to G and IVS12+ 21T to G were rare variations and the allele frequencies of both were 0.0075; while IVS2+ 34G to A, IVS4+ 39G to A, IVS12-5T to C and IVS16+ 51C to A were the single nucleotide polymorphisms and the allele frequency was 0.2635, 0.2156, 0.1505 and 0.3636 respectively. The frequency of IVS12-5T to C in the CHD group was significantly lower than that in the control group (5.42%versus 9.57%, P< 0.05). The variant of IVS14-35C to G was only detected in patients with CHD. Bioinformatic analysis showed that IVS12-5T to C might increase exon splicing ability comparing with the wild-type sequence.

CONCLUSIONThe CHD7 gene mutation may not be the main reason for sporadic congenital heart disease, whereas the single nucleotide polymorphism of IVS12-5T to C might play a protective role in the onset of this disease.

Objective: To investigate the association between the internal exposure levels of phthalic acid esters (PAEs) and executive function (EF) of preschool children. Methods: Between October 2008 and October 2010, pregnant women who accepted pregnancy health care services in four municipal medical and health institutions in Ma'anshan city, Anhui Province, were recruited as study objects. A total of 5 084 pregnant women and 4 669 singleton live births were enrolled in this cohort. The follow-up study was conducted from April 2014 to April 2015. A total of 3 725 data-completed preschool children aged 3 to 6 years older entered in this study. The method of analysis seven metabolites of phthalates in urine was high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) and divided objects into low (P₀-P₂₄), medium (P₂₅-P₇₄) and high (P₇₅-P₁₀₀) groups according to their exposure concentrations. To investigate the executive function of preschool children, we used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Univariate and multivariate statistical method was used to analyze the etiology association between the phthalate metabolites levels and preschool children's executive function. Results: In this study, 53.6% (1 997/3 725) of preschoolers were boys, children's age was (51.5±5.6) months. The detection rates of seven phthalate esters were: mono-n-methyl phthalate (MMP) was 99.89% (3 721/3 725); mono-ethyl phthalate (MEP) was 99.97% (3 724/3 725); mono-benzyl phthalate (MBzP) was 69.10% (2 574/3 725); mono-butyl phthalate (MBP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono- (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) were 100.00% and mono-ethylhexyl phthalate (MEHP) was 99.95% (3 723/3 725). The median concentrations of the seven phthalate metabolites were: 17.71, 15.36, 0.07, 155.24, 10.73, 14.67, 3.59 µg/L, respectively. The median concentrations corrected by urinary creatinine were 29.65, 26.65, 0.12, 257.73, 17.94, 24.80, 6.27 µg/g Cr, respectively. The P₂₅ and P₇5 concentration of the total PAEs metabolites corrected by urinary creatinine were 1.20 µmol/g Cr and 3.04 µmol/g Cr. After adjusted the relevant demographic information: children sex, children age in month, maternal age, parental education levels, household exposure to secondhand smoke and whether the child is the only child as confounds, multivariate logistic regression model showed that the risk of inhibitory self-control index (ISCI) dysplasia in MEHHP high concentration group and MEOHP high concentration group were 1.71 and 1.54 times (OR=1.71, 95% CI: 1.11-2.62; OR=1.54, 95% CI: 1.01-2.34) than in low concentration group. The risk of ISCI dysplasia in total PAEs metabolites high concentration group was 1.55 times (OR=1.55, 95% CI: 1.00-2.38) than in low concentration group. Conclusion Phthalates exposure may damage the executive function of preschool children.

Objective To analyze the transcriptome data of Zika virus(ZIKV)-infected human neuroblastoma cells SH-SY5Y by bioinformatics method,and to identify the potential genes involved in the pathogenic mechanism of ZIKV.Methods SH-SY5Y cells were infected with ZIKV.The total RNA was extracted and the differentially expressed genes(DEGs)were screened by transcriptome sequencing.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were performed to predict the biological processes,molecular functions,and signaling pathways mainly involved in the DEGs,and the results were verified by quantitative polymerase chain reaction(qPCR).Results A total of 259 DEGs were identified,including 172 up-regulated genes and 87 down-regulated genes.GO functional enrichment analysis showed that the DEGs were mainly related to extracellular matrix,response to stimulus,antimicrobial humoral response,and developmental process.KEGG pathway enrichment analysis revealed that the DEGs were predominantly associated to inflammatory reaction and immune response.The qPCR validation results of DEGs were basically consistent with the transcriptome sequencing results.Conclusion The expression of genes involved in extracellular matrix,response to stimulus,and regulation of inflammatory reaction is significantly altered in SH-SY5Y cells after ZIKV infection,suggesting that ZIKV may cause neurological lesions by remodeling the extracellular matrix and regulating inflammatory reaction.
