Conclusion miR-31 may be involved in the occurrence of ESCC in Han and Kazak nationality. miR-31 might be another risk factor in high incidence of ESCC in Kazak than Han nationality.

Objective To investigate the changes of hypoxia-inducible factor(HIF)-1α and hexokinase-Ⅱ(HK-Ⅱ)expression in human esophageal squamous cell carcinoma and its effect in glycolysis.Methods TE13 cells and Eca109 cells were cultured under hypoxic condition(1 ％O2)for different hypoxic time(6,12,24 and 48 hours).Cells cultured under normal oxygen condition(20％O2)were set as control.The changes of HIF-1α and HK-Ⅱ expressions at protein level were detected by Western blot.HIF-1α genes were specifically silenced with RNA interference technology(RNAi),and then the changes of HIF-1α and HK-Ⅱ expression were determined by realtime PCR and Western blot.Under normal oxygen and hypoxic condition,the changes of lactic acid concentration in cell culture medium were detected by spectrophotometric method.Results Under hypoxic condition,the expression of HIF-1α and HK-Ⅱ gradually increased as hypoxic time extended(P＜0.05),reached a peak at 12h and then gradually decreased as time extended.Compared with that under normal oxygen condition,the expression of HK-Ⅱ in TE13 cells and Eca109 cells significantly increased under hypoxic condition(P＜0.05),which was more significant after 12 hours hypoxia.The result of realtime PCR indicated that under normal oxygen condition the expression of HIF-1α at RNA level in TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference(P＜0.05).The expression of HK-Ⅱ at RNA level was consistent with the result of HIF-1α.Under normal and hypoxia condition,the expression of HK-Ⅱ at protein level in TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference,and the difference was statistic significant(P＜0.05).The lactic acid secretion of TE13 cells and Eca109 cells under hypoxia condition(14.707 ± 3.594 and 15.062 ±3.901)was higher than that under normal oxygen condition(6.070±1.839 and 6.891±1.592,P＜0.05).The lactic acid secretion of TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference,and the difference was statistic significant(P＜0.05).Conclusion The expressions of HIF-1α and HK-Ⅱ in human esophageal squamous cell carcinoma significantly increased under hypoxia conditions.The expression of HK-Ⅱ is closely correlated with lactic acid concentration and HIF-1α expression.HIF-1α may affect cell glycolysis through HK-Ⅱ.

Objective To investigate the inhibitory effect of blocking PI3K/AKT pathway by wortmannin on hypoxia-inducible factor 1α (HIF-1α) and the effect on the expression of glycolysis associated genes in human esophageal carcinoma cell lines TE1 and TE13,and to analyze the relation between PI3K/AKT-HIF-1α pathway and glycolysis in esophageal carcinoma cells. Methods Esophageal carcinoma cell lines TE1 and TE13 pretreated with wortmannin (2 μmol/L) were incubated under normoxic and hypoxic conditions.And each cell line was divided into four groups.The expression of HIF-1α and glycolysis associated genes GLUT-1,LDHA and HK-Ⅱ at protein level were measured by.Western blot.The expression of HIF-1α,GLUT-1,LDHA and HK-Ⅱ at mRNA level was determined by real-time PCR. The activities of LDH and HK-Ⅱ and lactic acid (LA)concentration in the culture supernatant were tested with spectrophotometer method.Results Under normoxic condition,HIF-1α was expressed in TE1 cells and the expression of HIF-1α was inhibited by wortmannin (2 μmol/L),the most significant inhibitory effect was at 12 hours,therefore 12 hours was selected for the subsequent hypoxia experiment.Compared with untreated cells,the expression of HIF-1α、HK-Ⅱ 、GLUT-1、LDH-A at protein level significantly decreased in TE1 and TE13 cells after pretreated with wortmannin (P ＜ 0.05),and the expression of HIF-1α、HK-Ⅱ at mRNA level significantly decreased (P＜ 0.05).Under normoxic and hypoxic conditions,the HK-Ⅱ and LDH activities in TE1 and Te13 esophageal carcinoma cells significantly decreased after treated with wortmannin compared with untreated cells (P＜0.05).Under hypoxia condition,the enzyme activity increased in untreated cells (P＜ 0.05). Under normoxic and hyp0xic conditions,the lactic acid concentration in the culture supernatant obviously decreased in cells treated with wortmannin compared with untreated cells (P＜ 0.05). Under hypoxia condition,lactic acid concentration increased in wortmannin treated cells (P ＜ 0.05). Conclusions Under normoxic and hypoxic conditions,wortmannin decrease lactic acid concentration through inhibiting the expression of HIF-1α and glycolysis associated genes, which indicate PI3K/AKT-HIF-1α pathway was closely related to glycolysis in esophageal carcinoma cells.

Objective To investigate the expression alteration and significance of long non-coding RNA (lncRNA)by GWAS(Genome-wide association study)between Esophageal squamous cell carcinoma(ESCC)and its adjacent normal esophageal tissues. Methods lncRNA and mRNA differential expression in 6 pairs of ESCC and matched non-cancerous tissues were screened by microarray assay. The target genes were predicted. Finally , GO(Gene Ontology)and Pathway analysis was used for the further research of lncRNA. Results A total of 680 lncRNA and 1472mRNA were differentially expressed at more than two-fold change(P ≤ 0.05,with 161lncRNA and 653mRNA up-regulated,519lncRNA and 819mRNA down-regulated between ESCC and its adjacent normal esophageal tissues. Gene ontology and pathway analysis results suggested that the differentially expressed genes were involved in 11 pathways.Theyare potentially associated with esophageal squamous cell carcinoma ,including post-translational protein modification ,mucin type O-Glycan biosynthesis and sphingolipid metabolism pathways , which mainly related to the changes of molecular function ,cellular components and biological processes. Through cis and trans analysis,a total of 15 differentially expressed lncRNA had cis-and/or trans-regulated target genes in the database,with 13 lncRNA had cis-regulated target genes,3 lncRNA had trans-regulated target genes,and 1 lncRNA had both cis- and trans-regulated target genes. Conclusion Compared with adjacent normal tissues ,a large number of lncRNA were expressed differentially in ESCC in Xinjiang Han people.Aberrantly expressed lncRNA may play important roles in ESCC development and progression through some signaling pathways ,which are of great significance for further search of new targets for the diagnosis and treatment of ESCC.

Objective To establish a Chinese hamster model of babesia infection, to find the changing pattern of organs and biochemical parameters in Chinese hamster infected with Babesia, and to promote the detection and treatment of babesiosis.Methods Healthy 5-week old Chinese hamsters were infected by intraperitoneal injection of blood containing Babesia.Blood samples were collected at 0, 2, 4, 6, 8, 10, 12, 14, 16, 23, 30, and 37 days after infection from 5 hamsters at each time point.Blood smears were prepared to detect the parasites using Giemsa staining.ELISA assay was employed to test the IL-2 concentration.The blood biochemical indexes were detected using an automatic biochemical analyzer.DNA was extracted from the whole blood and REAL-TIME RCR was performed to determine the reproduction of Babesia.Aftert the animals were sacrificed, the heart, lung, spleen, liver, and kidney were taken to analyze the changes of organ coefficients.Results The highest level of Babesia in the hamsters occurred on day 4 after the Babesia injection, and then showing a decreasing tendency.However, there was a transient increase on the 12th day after infection.The liver and spleen displayed most extensive response to the infection showing hepatomegaly and splenomegaly, but the variation of heart and kidneys coefficients was within the norm.There were prominent changes of blood cells, especially leucocytes, with two peaks at day 10 and 23 after the Babesia infection.The peak changes of blood biochemical indexes occurred at day 12 after infection.The concentration of serum IL-2 reached a peak on the 10th day after infection.Conclusions The Chinese hamsters display typical characteristics of tick-borne diseases such as hepatomegaly and splenomegaly.The immunological system is activated along with the infection and reaches a highest stage in the second week.Afterwards the Babesia can live in the hamster body for a long period of time.The results of this study provide useful information supporting further studies on the detection, treatment and prevention of Babesiosis.
