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.

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.

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.
