Objective:To explore the potential value of dynamic changes of inflammatory factors in evaluating the efficacy of platinum regimen in the first-line treatment of advanced lung adenocarcinoma(LUAD).Methods:A total of 121 patients with advanced LUAD without common target mutations who were admitted to Dongtai People's Hospital to receive first-line treatment with platinum regimen from January 2021 to January 2023 were selected,and relevant clinical data such as general information,hematuria routine,angiogenic factors,serum tumor markers,inflammatory factors,immunoglobulin and T lymphocyte indexes were collected and statisti-cally analyzed.Patients in complete response(CR)group and partial response(PR)group were classified as chemotherapy sensitive group;stable(SD)group and progressive(PD)group were classified as chemotherapy insensitive group according to response evaluation criteria in solid tumors(RECIST).Through univariate and multi-factor Logistics regression analysis,the influencing factors of first-line treatment efficacy of platinum regimen in patients with advanced LUAD were analyzed,and the regression equation y=1-1/(1+e-z)prediction model was established and verified.Receiver operating characteristic(ROC)curve was used to analyze the potential value of dynamic changes of inflammatory factors in evaluating the efficacy of platinum-based first-line treatment for advanced LUAD.Results:①Univariate and multivariate Logistic regression analysis showed that CEA,TNF-α,IL-6,IL-8,IL-18,IL-1β and hs-CRP were still the influencing factors for the efficacy of first-line chemotherapy of platinum regimen in patients with advanced LUAD(P<0.05).②Inflammatory factors TNF-α,IL-6,IL-8,IL-18,IL-1β and hs-CRP were included in multivariate Logistic regression analysis.After correcting confounders(Model 5),high levels of TNF-α,IL-6,IL-8,IL-18,IL-1β and hs-CRP were positively correlated with insensitivity after first-line chemotherapy of platinum regimen in advanced LUAD patients(P<0.05).Restrictive cubic spline model analysis showed that the dynamic changes of inflammatory factors and the insensitivity of patients with advanced LUAD after first-line chemotherapy all had a nonlinear dose-response relationship.With the increases of TNF-α,IL-6,IL-8,IL-18,IL-1β and hs-CRP levels,patients with advanced LUAD have a greatly increased risk of desensitization after first-line chemotherapy.③Stratified interaction test analysis showed that tumor stage,differentiation degree and lymph node metastasis before and after correction factors were significantly correlated with expressions of inflammatory factors(all P<0.05,all P interaction<0.05).④Prediction model based on the influence factors of inflammatory factors was well distinguished and accurate,the area under ROC curve(AUC)before and after internal validation for detecting chemotherapy sensitivity in patients with advanced LUAD treated with platinum regimen first-line therapy was 0.87(95%CI:0.81~0.93)and 0.88(95%CI:0.82~0.95),respectively,and the sensitivity were 89.69%and 89.75%,respectively,the specificity were 91.77%and 91.85%,respectively.Conclusion:Dynamic changes of inflammatory factors is an important factor affecting the chemotherapy efficacy of patients with advanced LUAD treated with platinum-containing regimen.With the significant decrease of inflammatory factors,the sensitivity of patients to chemotherapy is also significantly increased.

Objective To understand the degree of job burnout in nurses of intensive care unit (ICU) and to explore its influence on compliance with head-of-bed elevation in patients receiving mechanical ventilation.Methods A total of 42 nurses of ICU in Tengzhou Central People's Hospital were investigated on the level of job burnout with the nursing burnout scale (NBS) from September 2016 to February 2017. Besides, the implementation of head-of-bed elevation in patients receiving invasive mechanical ventilation without contraindications was inspected. The compliance with head-of-bed elevation was also calculated. The data was analyzed by SPSS 17.0.Results Among 42 nurses of ICU, there were 52.38% of them with severe emotion exhaustion, 59.52% with severe depersonalization, 40.47% with low personal accomplishment. The mean compliance with head-of-bed elevation was 64.29%. Spearman correlation analysis showed that the emotion exhaustion dimension had a negative correlation with compliance (r=-0.545,P<0.01). The depersonalization was negatively associated with compliance (r=-0.480,P<0.01). The sense of achievement had a positive correlation with compliance (r=0.516,P<0.01).Conclusions The job burnout in nurses of ICU has certain influences on compliance with head-of-bed elevation in patients receiving mechanical ventilation.

Objective To assess the expression pattern of protease-activated receptor 2 (PAR2) in human keratinocytes and to characterize its biological functions in the regulation of skin barrier.Methods Primary human keratinocytes and human N/TERT keratinocytes were used as the subject of this study.The expression and distribution of PAR2 in the keratinocytes were analyzed by using immunoflorescence staining and Western blot.Two different PAR2 agonists,trypsin and a PAR2-activating peptide (AP),as well as a PAR2-antagonistic peptide (H2N-FSLLRY-COOH) and a control peptide were used to induce the activation of PAR2 in the keratinocytes.Then,a fluorescence-based calcium mobilization assay was performed to evaluate the biological function of PAR2.Data were statistically analyzed by one-factor analysis of variance.Results Under normal culture conditions,PAR2 was weakly expressed in keratinocytes,and the expression was unaffected by culture medium composition or culture duration.Calcium mobilization was induced by trypsin of 50-250 nmol/L and the PAR2-activating peptide in a dose-and time-dependent pattern.The maximal activation of PAR2 was observed in keratinocytes treated with the PAR2 agonist HAN-SLIGKV-COOH of 75-250 μmol/L.The PAR2-antagonistic peptide (H2N-FSLLRY-COOH) obviously suppressed the increase in calcium mobilization induced by trypsin,while the control peptide PAR-RAP showed no inductive effect on the PAR2 activation based on the absence of calcium mobilization.The substrate-induced calcium release was complete within 250 seconds,and peaked at 50 seconds after the initial trypsin or PAR-AP stimulation.Moreover,the activation of PAR2 was accompanied by an increase in ERK phosphorylation and elicitation of MAPK signaling pathway in keratinocytes.Conclusions Human keratinocytes positively express PAR2,which can be activated by trypsin and PAR2-activating peptides,and the activation of PAR2 may influence the physiological function of keratinocytes by inducing intracellular calcium release.

Objective To explore the predictive value for coronary heart disease by epicardial adipose tissue(EAT) thickness and carotid intima-media thickness(IMT) measured with high-frequency ultrasound.Methods According to the results of coronary angiography, the cases were divided into the normal control group (29 patients),coronary artery disease group with single-vessel lesion (43 patients),coronary artery disease group with multi-vessels lesion (28 patients), respectively. EAT and IMT were measured by high-frequency ultrasound. Results The EAT in the three groups were (4.8 ± 1.3) mm, (7.6 ± 1.8) mm,(10.1±2.6) mm respectively, and the IMT were (0.8±0.1)mm,(1.0±0.2)mm,(1.1 ± 0.2)mmrespectively. In either coronary artery disease group with single-vessel lesion or multi-vessels lesion, the EAT and IMT were significantly higher than those in the normal control group ( P< 0.01 ). And the difference between groups of single-vessel lesion and multi-vessels lesion was also statistically significant (P< 0.01). The areas under receive operating characteristic(ROC) curve to predict coronary heart disease by EAT and IMT was 0.947 and 0.917, respectively, there was no significant difference between the two areas. For patient with coronary artery stenosis>50%, the sensitivity and specificity of EAT>6 mm were 90.1% and 86.2% ,respectively,the sensitivity and specificity of IMT>0.85 mm were 87.3% and 82.8%,respectively. Conclusions EAT and IMT measured by high-frequency ultrasound can precisely predictcoronary heart disease. EAT can be a new predictor to diagnose coronary heart disease.
