Objective To study the effects of diabetes mellitus(DM)on fas receptor-induced cardiomyocytes apoptosis and inflammatory response in patients with acute myocardial infarction(AMI).Methods 70 patients with ST-elevated myocardial infarction were divided into two groups:without(n=36)and with diabetes mellitus(n=34).Strepavidin-biotin ELISA was used to examine the serum levels of sFas,sFasL,TNF-? and IL-6.Results As the concentrations of sFas and sFasL immediately after primary PCI were higher in patients of AMI with DM than without DM(4.18?0.86 vs 3.30?0.82 ng/ml,6.15?1.56 vs 4.34?1.37 ng/ml,respectively,P

Objective To determine the correlation between the expression of interleukin 8(IL-8) and lymph node metastases in earlier uterine squamous cervical cancer and to study the mechanism of metastases of earlier squamous cervical cancer. Methods IL-8 mRNA expression was examined with reverse transcription polymerase chain reaction(RT-PCR) and tissue microarray to determine the expression of IL-8 protein. The matrix metalloproteinase 9( MMP-9) protein and microvessel density (MVD) in earlier squamous cervical cancer were decided respectively by antibody against IL-8, MMP-9 and CD-34 associated antigen and Immunohistochemical analysis. Results The cervical cancer with lymph node metastases express IL-8, MMP-9 and MVD at significantly higher level than negtive metastatic lymph node(P =0.00,0.00,0.02). Otherwise, the express of IL-8 correlated strongly and positively with MVD of cervical cancer(r =0.251,P

Objective To evaluate the effects of Ulinastatin (UTI) on the expressions of TNF-α,IL-6 and neurons apoptosis in cerebral cortex of rats after cardiopulmonary resuscitation (CPR).Methods Thirty-six healthy male adult Wistar rats were induced ventricular fibrillation untreated for 7 min and then received CPR.The animals were infused UTI 100 000 U/kg or phosphate-buffered solution (PBS) at once after ROSC.At 2,4 and 8 h after ROSC,cerebral cortex were removed to determine the mRNA expressions and levels of TNF-α protein and IL-6 protein,the translocation ratio of NF-κB p65 from cytoplasm to nucleus and the apoptotic neurons.Results The plasma levels of TNF-α (ng/mL) in animals of UTI group were (17.7 ± 1.4),(21.9 ± 2.1) and (17.1 ± 0.6) at 2,4 and 8 h after ROSC respectively,and significantly lower than those in PBS group at the given intervals.Mean while,the levels of IL-6 (ng/mL) were (208.9 ± 14.1),(281.5 ±25.9) and (251.8 ± 15.3) at 2,4 and 8 h after ROSC respectivèly in animals of UTI group,and lower than those in PBS group.The expressions of TNF-α mRNA and IL-6 mRNA and protein levels of TNF-α and IL-6 in UTI group were both lower than those in PBS group at given intervals,respectively.The translocation ratio of NF-κB p65 from plasma to nucleus in PBS group at each given interval after ROSC was significantly higher than that in UTI group.The number of viable neurons in cerebral cortex in UTI group was higher than that in PBS group,while the number apoptosis neurons was fewer in UTI group.Conclusions UTI attenuated the general inflammatory response after ROSC in rat,decreased the activation of NF-κB pathway,and subsequently attenuated the expression of TNF-α and IL-6,and finally decreased the neurons apoptosis.

Methods Toally 10 patients with severe abdominal infection were treated with damage control measures, including damage control surgery, improvement of pathological and physiological status of patients and surgical re-repairing, and the corresponding nursing measures including rapid completion of preoperative preparation, prevention of complications, nursing care to abdominal double cannula drainage, enteral nutrition and disease observation and mobilization the subjective initiative of patients. Results The average hosptitalization time was 21 days (14~29 days). There were 2 cases of anastomotic leakage and 1 case of pulmonary infection who all were cured after 14~29 d. Conclusion Damage control surgery is an effective treatment strategy for patients with severe abdominal infection and the corresponding nursing plays a positive role in improving the treatment effect.

ObjectiveTo investigate the correlation of miR-181c expression in peripheral blood mononuclear cells (PBMCs) with interferon-γ (IFN-γ), chemokine (C-X-C motif) ligand 10 (CXCL10), and Toll-like receptor 4 (TLR4) in children with autoimmune hepatitis (AIH). MethodsA total of 27 children with AIH who were admitted to The Affiliated Hospital of Yanbian University from March 2015 to May 2019 were enrolled as AIH group, and 30 healthy children who underwent physical examination during the same period of were enrolled as control group. The expression of miR-181c in PBMCs and the expression of IFN-γ, CXCL10, and TLR4 were measured for the two groups. The t-test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The Pearson correlation coefficient was used to investigate the correlation of miR-181c expression with each index, and a logistic regression analysis was used to investigate the influence of each factor on AIH. ResultsCompared with the control group, the AIH group had significantly higher levels of the liver function parameters aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), and total bilirubin (TBil) (t=14.445,20.064，11.728,13.822, all P＜0.001). The AIH group also had significantly higher levels of IgA, IgM, and IgG than the control group (t=7.772, 5147, and 6771, all P＜0.05). The AIH group had significantly lower relative expression of miR-181c in PBMCs than the control group (0.784±0173 vs 1.106±0.224, t=5.819, P＜0.05). Compared with the control group, the AIH group had significantly higher levels of IFN-γ and CXCL10 and mRNA expression of TLR4 (t=6.949, 12.303, and 13.835, all P＜0.05). The correlation analysis showed that in the children with AIH, the expression of miR-181c in PBMCs was negatively correlated with IFN-γ, CXCL10, TLR4, AST, ALT, GGT, TBil, and IgG (r=-0.316, -0.348, -0.322, -0.427, -0.442, -0.408, -0.396, and -0.321, all P＜0.05). The univariate logistic regression analysis showed that AST, ALT, GGT, TBil, IFN-γ, CXCL10, TLR4 mRNA, and miR-181c were all included in the regression model (all P＜0.05) and were the influencing factors for the onset of AIH. ConclusionChildren with AIH have downregulated expression of miR-181c in PBMCs, which is closely associated with IFN-γ, CXCL10, and TLR4, suggesting that miR-181c may affect the development of AIH in children by regulating the immune system.

Objective To investigate clinical characteristics and medium-term prognosis of the advanced elderly patients with mild ischemic stroke,and to evaluate the risk factors for poor clinical outcome.Methods The 574 elderly patients with mild acute ischemic stroke admitted in neurology department of our hospital were retrospectively studied from January 2016 to December 2017.All cases were divided into the advanced elderly group(n=276,≥80 years old)and elderly patient group(n=298,60-79 years old).Clinical characteristics were analyzed.After 12-month follow-up,the mid-term prognosis and risk factors for poor clinical outcome(mRS≥ 3)were analyzed in the two groups.Results Compared with the elderly patients,the advanced elderly patients were more often complicated with history of atrial fibrillation,diabetes and stroke(P ＜0.05).The scores of National Institute of Health stroke scale(NIHSS)and Modified Rankin Scale(mRS)were higher in the advanced elderly patients than in the elderly patients(1.37± 1.03 vs.0.94 ±0.43,2.79± 1.27 vs.1.92 ± 0.66,P＜0.001).The proportion of patients receiving anticoagulation treatment were lower in the advanced elderly patients than in the elderly patients,with no significant difference(P ＞0.05).After an average follow-up of(11.3 ± 1.5) months,the proportions of poor clinical outcome and mortality were higher in the advanced elderly patients than in the elderly patients(63.4％ or 175/276 vs.48.0％ or 143/298,25.7％ or 71/276 vs.16.1％ or 48/298,P＜0.05).Cox proportional hazard model analysis showed that age,baseline NIHSS score and mRS score,diabetes and stroke history were the risk factors for poor clinical outcome in elderly patients with mild ischemic stroke(all P＜0.05).Conclusions The advanced elderly patients with mild ischemic stroke have a severe clinical condition,higher rates of atrial fibrillation,diabetes and stroke history,and poor mid-term prognosis.Age,baseline scores of NIHSS and mRS,diabetes and stroke history are the risk factors for poor clinical outcome in elderly patients with mild ischemic stroke.
