Objective To investigate the expressions of long non-coding RNA antisense non-cod-ing RNA in the INK4 locus(lncRNA ANRIL)and microRNA-181b-5p(miR-181b-5p)in the serum of patients with colon cancer complicated with type 2 diabetes mellitus(T2DM)and their correlations with lymph node metastasis.Methods A total of 117 patients with colon cancer complicated with T2DM in the hospital from May 2019 to August 2022 were selected as colon cancer with T2DM group and divided into lymph node metastasis group(n=56)and no lymph node metastasis group(n=61)according to the lymph node metastasis status.Additionally,117 healthy volunteers with physical ex-aminations in the same period were selected as control group.Reverse transcription real-time quantita-tive PCR was used to detect the relative expression levels of serum lncRNA ANRIL and miR-181b-5p.Logistic regression analysis was conducted to explore the factors influencing lymph node metastasis in patients with colon cancer complicated with T2DM.Receiver operating characteristic(ROC)curve was plotted to analyze the diagnostic values of serum lncRNA ANRIL and miR-181b-5p levels for lymph node metastasis in patients with colon cancer complicated with T2DM.Pearson correlation a-nalysis was used to investigate the correlation between serum lncRNA ANRIL and miR-181b-5p ex-pression in patients with colon cancer complicated with T2DM.Results Compared with the control group,patients in the colon cancer with T2DM group had significant increased serum lncRNA ANRIL level and decreased miR-181b-5p level(P＜0.01).Compared with the no lymph node metastasis group,patients in the lymph node metastasis group had significant increased serum lncRNA ANRIL level and decreased miR-181b-5p level(P＜0.01).There were significant differences in TNM stage,degree of differentiation,and glycated hemoglobin(HbA1C)between the lymph node metas-tasis group and the no lymph node metastasis group(P＜0.05).History of diabetes,TNM stage,degree of differentiation,HbA1 C,and lncRNA ANRIL were influencing factors for lymph node me-tastasis(P＜0.05),while miR-181b-5p was a protective factor against lymph node metastasis(P＜0.05).There was a negative correlation between serum lncRNA ANRIL and miR-181b-5p levels(r=-0.440,P＜0.001).The ROC curve result showed that the areas under the curve(AUCs)for the diagnosis of lymph node metastasis by serum lncRNA ANRIL,miR-181b-5p,and their com-bination were 0.800,0.837 and 0.930 respectively.The combined diagnostic value was significant-ly higher than that of lncRNA ANRIL(Z=2.956,P=0.003)and miR-181b-5p(Z=2.117,P=0.034)alone.Conclusion Patients with colon cancer complicated with T2DM have increased ser-um lncRNA ANRIL level and decreased miR-181b-5p level,and both two indexes are correlated with lymph node metastasis.

Objective:To establish a method for rapid detection of OXA and par C resistance genes of Acinetobacter baumannii(Ab)by double nucleic acid colloidal gold strip and to develop kit.Methods:DNA of Ab was extracted by heating and boiling method.OXA and par C genes sequences of Ab were selected as target gene fragments based on NCBI.Primers were designed and labeled with 6-FAM,digoxin and biotin,respectively.Drug resistance gene detection reagents were developed,and nucleic acid gold test strips were used for rapid and visual detection.Molecular cloning and sequencing techniques were used to clone positive control samples and evaluate specificity,sensitivity and stability of kit.Results:DNA concentration and purity of Ab extracted by boiling method were good.Homology between cloned and sequenced plasmid DNA and gene sequence in GenBank database was 100%,respectively.Speci-ficity of kit was good,with only Ab showing positive results and other bacterial genera showing negative results;DNA concentration of Ab in double nucleic acid colloidal gold test strip decreased to 10-3 ng/μl,a red line still appeared,whose sensitivity was 10 times higher consistent with minimum detection limit of electrophoresis 10-2 ng/μl;test kits were tested at 3rd,6th and 9th months,and showed good stability.Conclusion:Double resistance detection kit established in this study can simultaneously detect OXA and par C resis-tance of Ab,who has advantages of high sensitivity,strong specificity,rapid and simple,and provides a new method for detection of carbapenem and quinolone antibiotic resistance of Ab.

Objective To explore the clinical effect of Weifuchun tablet combined with chemotherapy on patients with advanced non-small cell lung cancer (NSCLC).Methods Sixty-eight patients with advanced NSCLC was randomly divided into control group (n =34) treated with cisplatin + gemcitabine and treatment group (n =34) treated with Weifuchun tablet (1.436g × 2/d) and cisplatin + gemcitabine.After two treatment cycles,the clinical effect in both groups were evaluated.Results The clinical efficacy in the treatment group was 52.94％ (18/34),which in the control group was 41.18％ (14/34),there was no statistically significant difference between the two groups(x2 =0.94,P ＞ 0.05).The quality of life and the level of T lymphocytes were markedly improved,and the reduction of hemoglobin,leucocyte,and platelet,and nausea reaction were all significantly inhibited in treatment group compared with that in control group after two treatment cycles (x2 =4.12,4.66,5.96,4.12,5.90,all P ＜ 0.05).Conclusion Weifuchun tablet combined with chemotherapy effectively ameliorates the clinical symptoms of the patient with advanced NSCLC,reduces the toxic and side effects caused by chemotherapy,and improves the quality of life,which is worthy in the clinic.
