Objective To study the role of corn oil in the change of serum glucose, serum lipids and insulin in type 2 diabetes rats with insulin resistance, and attempt to find out its mechanism. Method High fat and sugar diet plus low-dose streptozotocin (STZ) was given to establish type 2 diabetes rat with insulin resistance model, the rats of which were randomly divided into normal group, model group, corn oil (0.8 mg/kg) group, rosiglitazone group. After Ig 6 weeks, fasting blood glucose (FBG), total cholesterol(TC), triglyceride(TG), low density lipoprotein(LDL), high density lipoprotein (HDL), fasting insulin (FINS), and insulin resistance index (HOMA-IR) were detected. Results Corn oil can elevate the level of HDL in diabetic rat, lower the levels of FBG, TC, TG, LDL, FINS and HOMA-IR. Conclusion Corn oil can improve insulin resistance, and decrease the serum glucose and lipid of type 2 diabetic rats.

Objective:To explore the expression and clinical significance of heme oxygenase-1 (HO-1) and quinone oxidoreductase (NQO-1) in children with different severity levels of mycoplasma pneumoniae (MP) infection.Methods:A total of 140 children with MP infection who were treated at the Affiliated Hospital of Jining Medical University from January to June 2022 were selected as the observation group, while 100 healthy children who underwent physical examination were selected as the control group. The serum levels of interleukin-2 (IL-2), IL-6, IL-10, IL-1β, tumor necrosis factor α (TNF-α), interferon γ (IFN-γ), HO-1, and relative expression of NQO-1 protein were compared between the control group and the observation group, as well as between children with different degrees of MP infection, Forced vital capacity (FVC), maximum expiratory volume in the first second (FEV 1), peak expiratory flow rate (PEF), 50% forced expiratory flow rate and maximum mid expiratory flow rate (MEF 25-70), 50% forced expiratory flow rate (MEF 50), and 25% forced expiratory flow rate (MEF 25). Pearson correlation method was used to analyze the correlation between the expression of HO-1 and NQO-1 with inflammatory factors and lung function indicators. The receiver operating characteristic (ROC) curve was used to analyze the value of HO-1 and NQO-1 expression in predicting severe MP. Results:The serum levels of IL-2, IL-6, IL-10, IL-1β, TNF-α, IFN-γ, and HO-1 in the observation group were significantly higher than those in the control group (all P<0.05), while the relative expression level of NQO-1 protein was significantly lower than that in the control group ( P<0.05). The FVC, FEV 1, PEF, MEF 25-70, MEF 50, and MEF 25 in the observation group were significantly lower than those in the control group (all P<0.05). The serum levels of IL-2, IL-6, IL-10, IL-1β, TNF-α, IFN-γ, and HO-1 in the observation group of severe children were significantly higher than those in mild children (all P<0.05), while the relative expression of NQO-1 protein, FVC, FEV 1, PEF, MEF 25-70, MEF 50, and MEF 25 were significantly lower than those in mild children (all P<0.05). HO-1 in children with MP infection is positively correlated with IL-6, IL-1β, and IFN-γ, while the relative expression level of NQO-1 protein is negatively correlated with IL-6, IL-1β, and IFN-γ (all P<0.05); HO-1 was negatively correlated with MEF 50 and MEF 25, while the relative expression level of NQO-1 protein was positively correlated with MEF 50 (all P<0.05). The area under the ROC curve for predicting the relative expression levels of HO-1 and NQO-1 proteins in severe MP was 0.871 and 0.934, respectively (all P<0.05). Conclusions:The expression of serum HO-1 and NQO-1 in children with MP infection is correlated with cytokines and lung function indicators, and has certain application value in predicting severe illness.

Objective:To describe the epidemiological characteristics of mental disorders in community resi-dents aged 18 years and over in the Chifeng City of Inner Mongolia Autonomous Region.Methods:Six thousand three hundred and seventy six individuals aged 18 years and over were sampled using stratified Probability-Propor-tional-to-Size Sampling in Chifeng City in 2010.All respondents were investigated by face-to-face interview.The Composite International Diagnostic Interview-3.0 Computer Assisted Personal Interview (CIDI-3.0-CAPI)was used to make diagnoses based on the definition and criteria of the Diagnostic and Statistical Manual of Mental Dis-orders,Fourth Edition (DMS-IV).Results:A total of 4528 subjects completed the CIDI-3.0-CAPI.Regarding anxi-ety disorder,mood disorder,substance use disorder,and impulse control disorder,the 30-day adjusted prevalence rates (95%CI)were 2.5%(2.08% -2.99%,0.9%(0.67% -1.23%),0.5%(0.34% -0.76%),and 0.6%(0.41% -0.86%)respectively,and the 12 -month prevalence rates were 4.5% (3.93% -5.15%),2.4%(2.0% -2.90%),1.1% (0.84% -1.45%),and 1.0% (0.74% -1.32%)respectively.The lifetime adjusted prevalence rates were 6.6% (5.92% -7.36%),6.5% (5.81% -7.24%),2.7% (2.26% -3.21%),and 1.4%(1.23% -1.95%)respectively.Conclusion:According to morbidity,anxiety disorders,mood disorder,substance use disorders and impulse control disorders are common in Chifeng City of Inner Mongolia Autonomous Region se-quencely,being a prominent public health problem.

Objective    To investigate the expression and biological function of centromere protein F (CENPF) in non-small cell lung cancer (NSCLC) and the association with prognosis. Methods    Through retrieving and analyzing the bioinformatics data such as Oncomine database, Human Protein Atlas (HPA), Kaplan-Meier Plotter, STRING and DAVID database, the expression of CENPF in both normal tissues and cancer tissues of lung cancer patients was identified, and the protein interaction network analysis, functional annotation and pathway analysis of CENPF with its associated genes were carried out. Results    CENPF was overexpressed in lung adenocarcinoma tissues, but not in normal tissues. The median overall survival (OS) of NSCLC patients with low expression of CENPF was significantly longer than that of patients with high expression of CENPF. Further sub-analysis showed that low expression group from lung adenocarcinoma patients had longer median disease-free survival and OS compared with high expression group patients. CENPF and its associated hub genes mainly affected the protein K11-linked ubiquitination in biological process, anaphase-promoting complex (APC) in cell composition, ATP binding in molecular function, and cell cycle in KEGG pathway. Conclusion    CENPF is regulated in tumorigenesis and progression of NSCLC, and its protein expression level has the value of early diagnosis and prognosis evaluation in lung adenocarcinoma. It is suggested that CENPF gene can be a potential target for molecular targeted therapy of NSCLC.
