Objective To investigate the expression and clinical significance of lncRNA insulin growth factor 2 anti-sense IGF2-AS in colorectal cancer;To verify the biological function of IGF2-AS in cells and to screen protein mole-cules regulated by IGF2-AS.Methods Using bioinformatics to predict the expression and clinical significance of IGF2-AS in colorectal cancer;Using RT-qPCR to detect the expression of IGF2-AS mRNA;Using small interfering RNA to knockdown IGF2-AS;Using CCK8,Transwell assay and flow cytometry to detect proliferation,migration,and apoptosis,respectively;Using label free quantitative proteomics to screen for factors regulated by IGF2-AS;Using databases such as GenCards,OMIM,TTD,and proteomics results screening for core targets regulated by IGF2-AS in colorectal cancer.Results Bioinformatics analysis showed that IGF2-AS was significantly upregulated in colorectal cancer(P＜0.001),its expression might be related to TNM stage(P＜0.01)and the presence of lymph node metastasis(P＜0.001);RT-qPCR results showed that as compared to the control group,the expression level of IGF2-AS mRNA was significantly up-regulated in colorectal cancer tissues(P＜0.01)and most colon cancer cells(P＜0.000 1);Clinical pathological data indicated that the expression of IGF2-AS was potentially asso-ciated with the lymph node metastasis(P＜0.05);The proliferation rate and migration rate of colorectal cancer cells transfected with IGF2-AS siRNA were significantly reduced(P＜0.000 1),and the apoptosis rate was signifi-cantly increased(P＜0.05);There were 13 proteins including KRAS,TCF7L2 and CASP3,that were potentially core targets regulated by IGF2-AS.Conclusions IGF2-AS is significantly up-regulated in colorectal cancer and may play a cancer promoting role in colorectal cancer development.

Objective:To evaluate the clinical efficacy of Chaihu Longgu Muli Decoction in the treatment of post-stroke depression.Methods:A total of 130 patients with post-stroke depression who met the inclusion criteria from April 2019 to December 2020 were enrolled in the study. The patients were randomly divided into two groups with 65 cases in each group. The control group was treated with Flupentixol and melitracen tablets on the basis of routine treatment, and the observation group was treated with Chaihu Longgu Muli Decoction on the basis of routine treatment. Both groups were treated for 4 weeks. TCM syndrome scores were performed before and after treatment. The levels of serum Hcy and hs CRP, Plasma 5-HT and brain-derived neurotrophic factor (BDNF) were detected by ELISA, and the ratio of neutrophils to lymphoblasts (NLR) was recorded.Results:The response rate was 92.3% (60/65) in the observation group and 75.4% (49/65) in the control group. There was significant difference between the two groups ( χ2=6.87, P=0.009). After treatment, the serum Hcy [(11.87±1.56) μmol/L vs. (16.69±1.77) μmol/L, t=16.47] and hs-CRP [(7.81±1.66) mg/L vs. (16.45±4.87) mg/L, t=13.54] in the observation group were significantly lower than those in the control group ( P<0.01), and Plasma 5-HT [(150.41±17.54) μg/L vs. (123.24±16.02) μg/L, t=9.22], BDNF [(19.45±2.48) μg/L vs. (12.56 ± 2.23) μg/L, t=16.66] were significantly higher than those in the control group ( P<0.01). After treatment, the NLR and TCM syndrome scores in the observation group were significantly lower than those in the control group ( t values were 6.03 and 7.15, respectively, all Ps<0.01). Conclusion:The Chaihu Longgu Muli Decoction combined with western medicine treatment can correct the levels of Hcy, hs-CRP, 5-HT, BDNF and NLR in peripheral blood, alleviate the state of depression and anxiety of patients with post-stroke depression.

Objective To investigate the impact of high mobility group box1 and GRACE score on the clinical prognosis of patients with acute coronary syndrome undergoing selective percutaneous coronary intervention. Methods A total of 380 consecutive patients initially diagnosed with acute coronary syndrome undergoing selec-tive PCI between January 2014 and March 2015 were included,with 200 of them assigned into low high mobility group box1(HMGB1<445 ng/mL)and the other 180 patients into high mobility group box1(HMGB1≥445 ng/mL).The baseline characteristics and laboratory indexes were collected on admission,GRACE score were calculat-ed at admission.The difference between the high and low high mobility group box1 were analzyed and the influenc-ing factors of patients with acute coronary syndrome undergoing selective percutaneous coronary intervention were studied. The mean follow-up period was 24 months,and the clinical end points were deaths from various causes and readmission for coronary heart disease. Results There were significantly differences statistically between the groups of high and low high mobility group box1 in clinical diagnosis. lipoprotein associated phospholipase A2, GRACE score,mean platelet volume,red cell distribution width,age,and left ventricular ejection fraction(P <0.05). The correlation analysis showed that HMGB1 was significantly related to lipoprotein associated phospholi-pase A2 and GRACE score,with the correlation coefficents of 0.575,0.836,respectively(P<0.05).COX analy-sis showed that HMGB1,lipoprotein associated phospholipase A2,GRACE score had statistical significance for survival outcomes(P<0.05),and the area under the ROC curve drawn by combining the three was 0.851(95% CI 0.811 ~ 0.891,P < 0.05). Conclusion There was a good correlation between HMGB1 and GRACE score. HMGB1 is a good predictor of clinical outcomes in the patients with acute coronary syndromes undergoing elective PCI treatment.

Mycobacterium (M.) vaccae is a fast-growing species of saprophytic bacteria that is widely distributed. To understand the host immune responses induced by M. vaccae isolated from bovine submaxillary lymph nodes, C57BL/6 mice were infected with reference strain M. vaccae Bacillus Calmette-Guérin (BCG) and isolated M. vaccae using intraperitoneal injections. Comparison of the bacterial replication and organ pathology between M. vaccae and M. vaccae BCG revealed that M. vaccae was more malignant than M. vaccae in mice. We also demonstrated that serum from the M. vaccae-infected mice contained a higher expression level of gamma-interferon (IFN-γ), tumor necrosis factor alpha, monocyte chemoattractant protein-1, interleukin (IL)-4, IL-12, IL-10 and transforming growth factor beta than did the other groups, especially after week 4. Furthermore, when the numbers of CD3⁺CD4⁺IFN-γ⁺ and CD3⁺CD4⁺IL4⁺ cells in the infected mice were observed by flow cytometry, we found that a powerful T helper 1 (Th1) response was induced by M. vaccae infection, which was associated with the emergence of CD3⁺CD4⁺IFN-γ⁺ cells. However, the Th1 response declined over time, which was associated with appearance of the CD4⁺CD25⁺FoxP3⁺ and CD4⁺CD25⁺CD152⁺Treg cell reaction. In addition, a strong Th2 response was found. Finally, we found that M. vaccae infection increased the production of type I IFNs, which was associated with a reduced Th1 response.
