Objective To investigate the prevention and treatment of biliary cardiac reflex in the interventional treatment of obstructive jaundice.Methods Totally 600 patients with obstructive jaundice were selected and divided into group A (without any preventive measures) and group B (with prevention and treatment,injection of atropine),and each group had 300 cases.The incidence of biliary cardiac reflex was observed in two groups.The relationship between the incidence of biliary cardiac reflex and gender,age,ECG abnormalities were analyzed in both groups.The timing of biliary cardiac reflex in interventional surgery was observed.Results The incidence of biliary cardiac reflex in group A was 30.67％ (92/300),which was significantly higher than that in group B (22/300,7.33 ％),and the difference was statistically significant (x2 =53.06,P＜0.05).But there was no significant difference between group A (4/300,1.33％) and group B (0) in the incidence of severe biliary cardiac reflex (x2 =0.45,P＞0.05).The incidence of biliary cardiac reflex in both groups was not associated with gender (both Φ=0.022,P＞0.05),but the incidence of biliary cardiac reflex in both groups was positively correlated with age and ECG abnormalities (Φage =0.593,0.229,ΦEcG =0.508,0.216,all P＜0.05).The incidence of biliary cardiac reflex was the highest in the balloon catheter on the stenosis or occlusion of the expansion in group A (55.43％,51/92) and group B (63.64％,14/22),which were higher than those of in puncture and angiography (all P＜0.05).Conclusion Preoperative injection of atropine can effectively prevent the occurrence of biliary cardiac reflex in interventional therapy,meanwhile the patients' own conditions are still need to be attention.

Objective To investigate changes in the firing activities of nucleus accumbens (NAc)neurons and their response to 5-HT7 receptor stimulation in a rat model of Parkinson’s disease (PD).Methods The firing activities and response of NAc neurons to 5-HT7 receptor agonist in PD rats were recorded by in vivo electroneurophysiology and neuropharmacology and then were compared with those in the sham group.Results The mean firing rate of NAc neurons was (5.46 ±0.88)Hz in the sham rats and (3.77 ±0.48)Hz in the PD rats. The firing rate of NAc neurons increased significantly compared with that in the sham rats (P <0.05).In PD rats, 65% of NAc neurons fired in bursts and 35% fired irregularly.However,in the sham rats,57.5% of NAc neurons fired in bursts and 42.5% fired irregularly.There was no significant difference in the firing pattern of NAc neurons between the PD and sham rats (P >0.05 ).Systemic administration of 5-HT7 receptor agonist AS1 9 increased the firing rate of NAc neurons in the sham and PD rats.This excitation was significant at a high dose of 1 60 μg/kg for NAc neurons in the sham rats (P <0.05).However,the excitation produced by AS1 9 was significant at a high dose of 80 μg/kg in PD rats (P <0.05).The cumulative dose-produced excitation in the PD rats was lower than that in the sham rats.The effects induced by AS1 9 were reversed by the 5-HT7 receptor antagonist SB269970 in both groups.Conclusion The reinforced firing activity of NAc neurons might be mediated by 5-HT7 receptor in the neurons of PD rats.

Objective:To investigate the effects of long non-coding RNA Wilms tumor 1 associated protein pseudogene 1(WTAPP1)on the proliferation,invasion,migration and Wnt/β-catenin signaling pathway of nephroblastoma cells. Methods:Real-time fluorescence quantitative PCR was used to detect the relative expression level of WTAPP1 in 48 cases of nephroblastoma tumor tissues and their matched adjacent tissues,human nephroblastoma cells(SK-NEP-1)and normal renal epithelial cells(PCS-400-01 0,PCS-400-011 and PCS-400-01 2).The clinicopathological characteristics and prognosis of nephroblastoma patients with high or low WTAPP1 expression of were analyzed and compared.SK-NEP-1 cells were infected with lentivirus carrying the full-length WTAPP]gene(WTAPP1 overexpression)or shRNA targeting WTAPP1(shWTAPP1).Then,colony formation assay and CCK-8 assay were used to assess the proliferation of SK-NEP-1 cells,wound healing assay and Transwell assay were used to evaluate the migration and invasion activity of SK-NEP-1 cells respectively,and Western blotting was used to examine the relative expression levels of Wnt3a,β-catenin,C-myc and Survivin proteins. Results:The relative expression level of WTAPP1 in cancer tissues was higher than that in adjacent tissues(P＜0.05).The relative expression level of WTAPP1 in SK-NEP-1 cells was higher than that in normal renal epithelial cells(PCS-400-01 0,PCS-400-01 1 and PCS-400-01 2;P＜0.05).WTAPP1 expression was associated with the clinical stages of nephroblastoma(P＜0.05)but not with the age,gender,tumor diameter or lymph node metastasis of nephroblastoma patients(all P＞0.05).The 5-year survival rate of WTAPP1-high patients was significantly lower than that of WTAPP1-low patients(P＜0.05).The proliferation,migration and invasion activities of SK-NEP-1 cells were significantly increased after WTAPP1 overexpression(all P＜0.05)while decreased after WTAPP1 silencing(all P＜0.05).The relative expression levels of Wnt3a,β-catenin,C-myc and Survivin proteins were significantly upregulated after WTAPP1 overexpression(all P＜0.05)while decreased after WTAPP1 silencing(all P＜0.05). Conclusion:WTAPP1 is correlated with the clinical stages and prognosis of nephroblastoma patients and may promote the proliferation,invasion and migration of tumor cells by activating Wnt/β-catenin signaling pathway.

OBJECTIVETo screen the genes related to cell cycle under regulation by KIAA0101 in gastric cancer.

METHODSRT-PCR was used to detect the expression level of KIAA0101 gene in gastric cancer tissue and paired adjacent tissues. GO function enrichment analysis and KEGG pathway enrichment analysis were carried out using DAVID database. KEGG was used to map the pathways and the corresponding genes were analyzed. The list of genes associated with the KIAA0101 expression pattern was imported into TCGA cBioPortal to analyze the relationship between the interacting genes and generate a genetic topology map. The candidate genes were screened by RT-PCR.

RESULTSThe expression level of KIAA0101 mRNA was significantly higher in cancer tissues than in paired adjacent tissues (1.104 ± 0.379 0.421 ± 0.172; =0.0179). The system screened genes related with KIAA0101 from 478 tissues by pooled analysis of the expression intensity of all the gene probes. GO function analysis showed that the differential genes were mainly enriched in protein phosphorylation, RNA processing, cell cycle, DNA metabolism, protein transport, acetylation, apoptosis, proteolysis, and redox. The changes in the expression level of KIAA0101 mainly affect the gastric cancer-related pathways including cell cycle, spliceosome, DNA replication, and p53 signal transduction pathway. KEGG pathway maps and gene topology maps showed that the genes related to KIAA0101 (such as BUB1B, MAD2L1, CDC45, CDK1, CCNE1 and CCNB2) were also related to cell cycle. RT-PCR results confirmed significant increments of the expression levels of BUB1B, MAD2L, CDK1, CCNE1, and CCNB2 mRNA in gastric cancer tissues as compared with the paired adjacent gastric tissues ( < 0.05), but CDC45 mRNA did not show significant differential expression in gastric cancer tissues ( > 0.05).

CONCLUSIONSKIAA0101 may affect cell cycle by regulating the expression of BUB1B, MAD2L1, CDK1, CCNE1 and CCNB2, and this finding may provide evidence for understanding how KIAA0101 affects cell cycle and for screening of tumor markers and selection of drug targets.

OBJECTIVETo investigate and improve the diagnosis and management of small-cell neuroendocrine carcinoma of the stomach (SCNECS).

METHODSThe clinicopathological information and survival data of 21 cases of SCNECS treated in our hospital from January 2003 to December 2012 were analyzed retrospectively.

RESULTSThe median survival time of the 21 cases was (12.1±1.6) months. The 1-year overall survival rate of the patients was 33.3%. Univariate analysis showed that the risk factors of survival were tumor size, lymph node status, tumor stage, treatment and radical operation or not (P<0.05 for all). Multivariate analysis indicated that independent risk factors were tumor size ≥4.6 cm, lymph node metastasis and tumor stage III/IV (P<0.05 for all). Radical operation and comprehensive treatment (surgery + postoperative chemotherapy) were independent protective factors (all P<0.05).

CONCLUSIONSSCNECS is a rare malignant tumor with early metastasis and poor prognosis. Tumor size, stage, lymph node status, and treatment have potential impact on the prognosis. Comprehensive treatment based on radical operation may improve the survival of SCNECS patients.
