Macrophage migration inhibitory factor (MIF) is a cytokine of pluripotent biological behavior. With the in-depth research of MIF on molecular biology and clinic, it has been found that MIF is closely re-lated to the gastrointestinal tumor' s proliferation and invasion. In this review, we mainly discuss the correla-tion between MIF and gastrointestinal tumor.

Objective:To investigate the changes of intestinal flora and serum amino acid levels in elderly patients with Parkinson's disease(PD)at different stages, and to provide evidence for diagnosis, prevention and treatment of PD.Methods:A total of 140 elderly PD patients diagnosed and treated in our hospital from January 2018 to August 2019 were enrolled and divided into PD course <5 years group(n=70)and PD course≥5 years group(n=70). Ninety subjects without PD confirmed by medical examination in our hospital were included as the control group.Real-time fluorescence quantitative PCR of 16S rDNA gene was used to detect levels of Bifidobacterium, Lactobacillus, Clostridium prasus, Enterococcus, Enterobacter, Prevotella copri and Akkermansia muciniphila bacteria in the gut, and the high-performance liquid chromatography was used to detect the serum amino acids in the three groups.Results:Compared with the control group, the levels of Bifidobacterium, Lactobacillus, Clostridium prasalis and Prevotella copri in the intestines were decreased and Enterobacter level was increased in PD course <5 years group and PD course≥5 year group( F=20.863, 32.251, 23.166, 24.683 and 10.136, all P<0.001). The serum levels of methionine, tryptophan, lysine and glutamate in PD course <5 years and PD course≥5 year group were decreased as compared with the control group( F=5.858, 5.877, 4.183 and 25.462, all P<0.05). Spearman correlation analysis showed that serum glutamate level was positively correlated with Clostridium prastia in the intestine( r=0.647, P=0.002)and negatively correlated with Prevotella copri( r=-0.559, P=0.010). Multivariate Logistic regression analysis showed that the protective factors in the intestines of elderly PD patients were Bifidobacterium( OR=0.186, 95% CI: 0.054-0.637, P=0.007), Lactobacillus( OR=0.283, 95% CI: 0.098-0.816, P=0.020), Clostridium prastia( OR=0.232, 95% CI: 0.063-0.851, P=0.028), and Prevotella copri( OR=0.222, 95% CI: 0.058-0.851, P=0.028), and the risk factor was Enterobacter( OR=5.119, 95% CI: 1.406-18.636, P=0.013). Conclusions:The decreases of Bifidobacterium, Lactobacillus, Clostridium, Prevotella copri and Enterobacter levels in the intestinal tract of PD patients, and the decrease of serum glutamate level may be correlated to the progression of PD.

Objective To investigate the expression profile and biological function of lncRNAs in urothelial cancer stem cells and explore whether they can be biomarkers for prediction of clinical characteristics for bladder cancer patients.Methods Microarray analysis was performed to identify differentially expressed lncRNAs in cancer stem cells and parental cancer cells.Expression profiles were validated by Coding Potential Caculator analysis,real-time polymerase chain reaction.By performing in vitro sphere formation assays,J82 cells with lentivirus-based knockdown of lncRNA-BCSC (bladder cancer stem cells) were used to confirmed its function.Samples were obtained from patients who underwent TURBT between January 2009 and December 2012.All tissues were initially confirmed by pathologists.The association of the clinicpathologic of bladder cancer and lncRNA-BCSC expression was analyzed by x2 analysis.Results 750 lncRNAs were highly expressed from microarray analysis in bladder cancer stem cells.Among these,lncRNA-BCSC was identified as potentially maintaining self-renewal of cancer stem cells.Knockdown of this transcript in J82 cells inhibited spheroid formation.lncRNA-BCSC expression were higher in 54.8％ (57/104) bladder cancer tissues.Moreover,using x2 analysis,lncRNA-BCSC expression in primary tumors was found to be a predictor for recurrence following transurethral resection in patients with nonmuscle-invasive bladder cancer (P =0.009).Conclusions Our study provides strong evidence that lncRNA-BCSC are indispensable modulators of self-renewal ability of bladder cancer stem cells.Overexpression of lncRNA-BCSC may have a predictive value for early recurrence in patients suffering from nonmuscle-invasive bladder cancer.

Objective To explore the role of xCT in the metastasis and drug resistance of nasopharyngeal carcinoma (NPC),to provide new evidences for the mechanism of NPC metastasis and drug resistance,and to enhance effects of chemotherapy.Methods Fluorescence quantitative polymerase chain reaction (PCR) and Western blot were used to detect the xCT expression of 5-8F and 6-10B.The xCT eukaryotic expression vector was constructed to transient transfect 6-10B cell lines.The 5-8F cell lines were treated with xCT antisense oligodeoxynucleotide (ASO).Scratching assay and transwell method were used to detect the cell metastasis and invasion abilities.The expressions of matrix metalloproteinase 1 (MMP1) of all the cell lines were surveyed by Western blot.Results The results of fluorescence quantitative PCR and Western blot showed that the expression of xCT in 5-8F was higher than 6-10B in the levels of mRNA and protein.Exogenous overexpression of xCT enhanced metastasis and invasion abilities of 6-10B cells.Silencing and inhibition of xCT could decrease metastasis and invasion abilities of 5-8F cells.The expressions of MMP1 protein in 5-8F were higher than 6-10B,and they were positively correlated with the expression of xCT.Conclusions xCT is closely related to the metastasis and invasion abilities of nasopharyngeal carcinoma.xCT could enhance the metastasis and invasion abilities of NPC cells.xCT might mediate proliferation and matastasis/invasion of NPC cells through MMP1.

There was a statistically significant pre-/post-treatment difference in the posterior femoral angle in the control group (P<0.05). There were statistically significant post-treatment differences in the foot dorsiflexion angle and popliteal fossa angle between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in the GMFM score and the ADL score in the two groups (P<0.05). There were statistically significant post-treatment differences in the GMFM score and the ADL score between the treatment and control groups (P<0.05).
