Objective To investigate the relationship between the expression of MIF mRNA and TNF-α in the lung tissue of rats with acute necrotizing pancreatitis (ANP) and explore their mechanism of action in acute lung injury during the course of ANP. Methods A total of 40 Sprague-Dawley rats were randomly divided into four groups (n = 10 in each group) : the sham operation (SO) group, ANP 3h group, 6h group, 12h group. The model of ANP was induced by retrograde injection of 5% sodium tanrocholate (0. 1 ml/100 g) into the biliary and pancreatic duct. The level of serum amylase was determined;pancreatic and lung tissues were harvested for pathological examination, and wet/dry weight ratios were estimated. Intrapulmonary expression of MIF mRNA was assayed by semi-quantitative RT-PCR. TNF-α in pulmonary homogenate was measured by immunoradiometric assay. Results Serum amylase, wet/dry weight ratios of pancreatic and lung tissues all significantly increased, and pathological injuries aggravated with time in ANP groups. Levels of TNF-α in ANP 3h, 6h, 12h group were (0.69 ± 0. 107) ng/ml, (1.64 ± 0. 10) ng/ml and (0.92 ± 0.11) ng/ml, and expression of MIF mRNA were 1.97±0.09, 2.55±0.23, 3.29±0.26, which were significantly higher than those in control group [(0. 19±0.06)ng/ml, 1.21±0.34, P<0.01]. lntrapulmonary expression of MIF mRNA was positively associated with lung pathological injuries, wet/dry weight ratio, and TNF-α(r = 0. 637, r = 0.684, r = 0.858, P < 0.01). Intrapulmonary levels of TNF-α was positively associated with lung pathological injuries, wet/dry weight ratio (r=0.540, r=0.421, P<0.01). Conclusions MIF mRNA was over- expressed and level of TNF-α was significantly increased in pulmonary tissue in rats with ANP, and this may be one of the mechanisms in the pathogenesis of lung injury in ANP.

In recent years, more and more attention has been paid to the occurrence and harm of delirium, and intensive care unit (ICU) delirium has become a hot issue. The incidence of delirium in ICU patients is much higher than that of general wards, all kinds of complications caused by delirium and increased mortality should win enough attention of the clinicians. There is no uniform standard for the diagnosis and evaluation of ICU delirium, which is a major problem that affects clinicians in the early diagnosis and assessment of prognosis. By reviewing the domestic and international researches of ICU delirium, the latest progress of diagnostic and assessment instruments for delirium in ICU is stated, which provides an important basis for the early identification and diagnosis of delirium in ICU.

Objective:To evaluate the effects of dexmedetomidine on the content of glutamate and expression of NR1 in hippocampus of mice with endotoxemia and the role of cholinergic anti-inflammatory pathway.Methods:Eighty clean-grade male C57BL/6 mice, aged 8 weeks, weighing 24-28 g, were divided into 4 groups ( n=20 each) using a random number table method: control group (group C), endotoxemia group (group LPS), dexmedetomidine group (group DEX) and alpha-bungarotoxin (α-BGT) group.Lipopolysaccharide 20 mg/kg was intraperitoneally injected to establish the model of endotoxemia in LPS, DEX and α-BGT groups. Dexmedetomidine 40 μg/kg was intraperitoneally at 15 min before establishing the model in DEX and α-BGT groups.In group α-BGT, alpha-7 nicotinic acetylcholine receptors specific agonist α-BGT 1 μg/kg was intraperitoneally injected at 15 min before injecting dexmedetomidine.Ten mice taken in each group were selected to collect the blood samples from the eyeball and then sacrificed, and hippocampi were isolated.Enzyme-linked immunosorbent assay was used to measure the concentration of serum S100β protein and NSE, and high-performance liquid chromatography was used to determine the content of glutamate in hippocampus.Ten mice in each group were sacrificed at 6 h after establishing the model to detect the expression of NR1 in hippocampus by immumofluorescence method. Results:Compared with group C, the concentrations of serum S100β protein and NSE concentrations and hippocampal glutamate content were significantly increased, and NR1 expression was up-regulated in LPS, DEX and α-BGT groups ( P<0.01). Compared with group LPS, the concentrations of serum S100β protein and NSE concentrations and hippocampal glutamate content were significantly decreased, and NR1 expression was down-regulated in DEX and α-BGT groups ( P<0.01). Compared with group DEX, the concentrations of serum S100β protein and NSE concentrations and hippocampal glutamate content were significantly increased, and NR1 expression was up-regulated in group α-BGT ( P<0.01). Conclusion:The mechanism by which dexmedetomidine alleviates cerebral injury is associated with activating cholinergic anti-inflammatory pathway, decreasing glutamate content and down-regulating NR1 expression in mice with endotoxemia.

Objective To explore the characteristic of early evaluation of patients with amplitude-integrated electroencephalogram (aEEG) on brain function prognosis after cardiopulmonary cerebral resuscitation (CPCR). Methods A retrospective analysis of the clinical data of patients with adult CPCR in intensive care unit (ICU) of Henan Provincial People's Hospital from March 2016 to March 2017 was performed. The length of stay, recovery time, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, aEEG and Glasgow coma scale (GCS) within 72 hours were recorded. The main clinical outcome was the prognosis of brain function (Glasgow-Pittsburgh cerebral performance category, CPC) in patients with CPCR after 3 months. Relationship between aEEG and GCS and their correlation with brain function prognosis was analyzed by Spearman rank correlation analysis. The effects of aEEG and GCS on prognosis of brain function were evaluated by Logistic regression analysis. The predictive ability of aEEG and GCS for brain function prognosis was evaluated by receiver operating characteristic (ROC) curve.Results A total of 31 patients with CPCR were enrolled, with 18 males and 13 females; mean age was (41.84±16.96) years old; recovery time average was (19.42±10.79) minutes; the length of stay was (14.84±10.86) days; APACHE Ⅱ score 19.29±6.42; aEEG grade Ⅰ(normal amplitude) in 7 cases, grade Ⅱ (mild to moderate abnormal amplitude) in 13 cases, grade Ⅲ (severe abnormal amplitude) in 11 cases; GCS grade Ⅰ (9-14 scores) in 7 cases, grade Ⅱ (4-8 scores) in 14 cases, grade Ⅲ (3 scores) in 10 cases; 19 survivals, 12 deaths; the prognosis of brain function was good (CPC 1-2) in 8 cases, and the prognosis of brain function was poor (CPC 3-5) in 23 cases. There was no significant difference in age, gender, recovery time, length of stay and APACHE Ⅱ score between two groups with different brain function prognosis, while aEEG grade and GCS grade were significantly different. Cochran-Armitage trend test showed that the higher the grade of aEEG and GCS, the worse the prognosis of CPCR patients (bothP-trend < 0.01). With the increase in GCS classification, the classification of aEEG was also increasing (r = 0.6206,P = 0.0003). Both aEEG and GCS were positively correlated with the prognosis of brain function (r1 = 0.7796,P1 < 0.0001;r2 = 0.7021,P2 < 0.0001). Univariate Logistic regression analysis showed that aEEG and GCS had significant effect on early brain function prognosis [aEEG: odds ratio (OR) = 37.234, 95％confidence interval (95％CI) = 3.168-437.652,P = 0.004, GCS:OR = 12.333, 95％CI = 1.992-76.352,P = 0.007]; after adjusting for aEEG and GCS, only aEEG had significant effect on the early prognosis of brain function (OR = 26.932, 95％CI = 1.729-419.471,P = 0.019). The ROC curve analysis showed that in the evaluation of the prognosis of CPCR patients with brain function, the area under ROC curve (AUC) of aEEG was 0.913, when the cut-off value of aEEG was 1.5, the sensitivity was 95.7％ and the specificity was 75.0％. The AUC of GCS was 0.851, the best cut-off value was 1.5, the sensitivity was 91.3％ and the specificity was 62.5％.Conclusion aEEG and GCS scores have a good correlation in the evaluation of brain function prognosis in patients with CPCR, the accuracy of aEEG in the early evaluation of the prognosis of patients with CPCR is higher than the GCS score.

The prevalence of obesity-associated conditions raises new challenges in clinical medication. Although altered expression of drug-metabolizing enzymes (DMEs) has been shown in obesity, the impacts of obese levels (overweight, obesity, and severe obesity) on the expression of DMEs have not been elucidated. Especially, limited information is available on whether parental obese levels affect ontogenic expression of DMEs in children. Here, a high-fat diet (HFD) and three feeding durations were used to mimic different obese levels in C57BL/6 mice. The hepatic expression of five nuclear receptors (NRs) and nine DMEs was examined. In general, a trend of induced expression of NRs and DMEs (except for and ) was observed in HFD groups compared to low-fat diet (LFD) groups. Differential effects of HFD on the hepatic expression of DMEs were found in adult mice at different obese levels. Family-based dietary style of an HFD altered the ontogenic expression of DMEs in the offspring older than 15 days. Furthermore, obese levels of parental mice affected the hepatic expression of DMEs in offspring. Overall, the results indicate that obese levels affected expression of the DMEs in adult individuals and that of their children. Drug dosage might need to be optimized based on the obese levels.

Objective: To investigate the expression change, biological role and action mechanism of long non-coding RNA (lncRNA) LINC00978 in non-small cell lung cancer (NSCLC). Methods: The expression levels of LINC00978 in tumor tissues and serum samples of NSCLC patients were detected by the qRT-PCR. The effects of knockdown and overexpression of LINC00978 on the biological function of A549 cells were determined by the CCK-8, colony formation, Transwell migration and invasion assays. The action mechanisms of LINC00978 in NSCLC were investigated by the flow cytometry, qRT-PCR and western blot, respectively. Results: The expression levels of LINC00978 in the tissues ( t =2.465, P ＜0.05) and serum samples ( t =8.781, P ＜0.01) of NSCLC patients increased. The knockdown of LINC00978 inhibited the proliferation, migration and invasion of A549 cells ( P ＜0.01) and induced cell cycle arrest at G1 phase and apoptosis of A549 cells ( P ＜0.01). The knockdown of LINC00978 downregulated the expression of Cyclin D1 and Bcl-2 , and upregulated the expression of Bax ( P ＜0.05). In addition, the knockdown of LINC00978 inhibited the expression of N-cadherin, Vimentin, Snail, Slug and Twist, and promoted the expression of E-cadherin ( P ＜0.05). The overexpression of LINC00978 had the opposite effect. Conclusion LINC00978 is highly expressed in NSCLC and can promote the occurrence and progression of NSCLC, which may serve as a potential target for the diagnosis and therapy of NSCLC.
