Objective:To investigate the effects of intervention mapping on cardiopulmonary function for patients with acute heart failure in compensatory period, so as to provide references for their early rehabilitation activities.Methods:A total of 90 patients with acute heart failure admitted to Fuwai Central China Cardiovascular Hospital from October 2018 to October 2019 were enrolled in the present study. They were divided into experimental group and control group according to draw-lots-method, with 45 cases in each group. The control group received the routine care and activity plan, while the experimental group implemented intervention mapping-based stage early rehabilitation program. The indicators included 6MWT, forced expiratory volume in one second (FEV 1), brain natriuretic peptide (BNP) as well as Minnesota Living with Heart Failure Questionnaire (MLHFQ), and the intervention effects were compared between the two groups. Results:There were no significant differences in FEV 1, 6MWT, BNP and MLHFQ scores between the two groups at admission ( P>0.05). On discharge, FEV 1, 6MWT were (2.17±0.44) L, (273.09±55.80) m in the experimental group, significantly higher than (1.94 ± 0.39) L and (236.44 ± 50.99) m in the control group; the plasma BNP were (676.79 ± 78.75) ng/L in the experimental group, significantly lower than (736.05 ± 78.77) ng/L in the control group; in addition, the physical demention, emotional dimenson, other demension scores and total scores of MLHFQ in the experimental group were (65.39 ± 5.02), (67.56 ± 4.99), (66.05 ± 4.16) and (66.33 ± 2.63) points, significantly higher than (59.79 ± 5.94), (64.33 ± 5.93), (62.76 ± 4.47), (62.36 ± 2.98) points in the control group, the differences were statistically significant ( t values were 2.56-6.51, all P<0.05). Conclusions:Designing and implementing stage early rehabilitation program using intervention mapping can promote cardiopulmonary function and quality of life of patients with acute heart failure in compensatory period.

Objective:To observe the clinical efficacy of angiotensin-receptor neprilysin inhibitors (ARNI) in the treatment of maintenance hemodialysis (MHD) with heart failure.Methods:The clinical data of heart failure patients who accepted MHD in Central China Fuwai Hospital were retrospectively collected. All patients accepted regular treatments of heart failure, and then the treatment group was treated with ARNI, while the control group was treated with valsartan. The treatment course was 6 months. The cardiac parameters: left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic dimension (LVESD), pulmonary artery pressure, right ventricular end-diastolic dimension (RVED), right atrial end-diastolic dimension (RAED), N-terminal pro-B-type natriuretic peptide (NT-pro BNP), and serum potassium were collected and compared between the two groups. Multivariate ordered logistic regression analysis was adopted to analyze the influencing factors of treatment effect.Results:A total of 60 MHD patients with heart failure were enrolled with age of (53.92±11.88) years old, 37 males (61.7%), dialysis age of (27.83±12.92) months, and blood pressure of (154.22±15.27) mmHg/(85.43±12.31) mmHg. (1) There was no significant difference of the clinical data and cardiac parameters between the treatment group ( n=30) and the control group ( n=30) before treatment (all P>0.05); (2) After treatment of 6 months, the total effective rate [28/30(93.3%)] in the treatment group was significantly higher than that in the control group [20/30(66.7%)] and the rehospitalization rate [2/30(6.7%)] in the treatment group was significantly lower than that in the control group [10/30(33.3%)] (both P<0.05); (3) After treatment of 6 months, LVEF, LVEDD, LVESD, pulmonary artery pressure, RVED, RAED, NT-pro BNP, and blood pressure were all improved significantly compared with the baseline in both groups (all P<0.05) and there was no significant difference of serum potassium and body weight before and after treatment in the two groups (all P>0.05); (4) After treatment of 6 months, LVEF in the treatment group was higher than that in the control group and LVEDD, LVESD, pulmonary artery pressure, NT-pro BNP, and blood pressure in the treatment group were lower than those in the control group (all P<0.05). There was no significant difference of RVED, RAED, serum potassium and body weight between the two groups after treatment (all P>0.05); (5)The difference values before and after treatment of LVEF, LVEDD, LVESD, NT-pro BNP, body weight, systolic blood pressure, and diastolic blood pressure were different between the two groups (all P<0.05); (6)Therapy method ( β=-1.863, 95% CI -2.948-0.777, P=0.001) and residual urine ( β=-1.686, 95% CI -3.079- -0.293, P=0.018) were independent influencing factors of treatment effect (the treatment effect of ARNI was better than that of valsartan; the treatment effect of patients with normal urine volume was better than that of patients with oliguria and anuria). Conclusions:ARNI can effectively improve cardiac function in MHD patients with heart failure, inhibit ventricular remodeling, and improve disease prognosis.

Purpose: The aim of our study was to investigate the value of baseline and preoperative neutrophil-to-lymphocyte ratio (NLR) in predicting the pathological response and disease-free survival (DFS) of neoadjuvant chemotherapy alone or combined with programmed cell death-1 (PD-1) checkpoint inhibitors in patients with resectable non‒small cell lung cancer (NSCLC). Materials and Methods: Resectable NSCLC patients who underwent neoadjuvant chemotherapy alone or combined with PD-1 checkpoint inhibitors between January 2018 and January 2020 were included. Peripheral venous blood samples of the patients were collected within 3 days prior to the first neoadjuvant treatment and within 3 days prior to surgery. Results: A total of 79 patients in neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group and 89 patients in neoadjuvant chemotherapy alone group were included. Thirty-five point four percent of the patients achieved pathological complete response (pCR) in neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group, whereas only 9.0% reached pCR in the group of neoadjuvant chemotherapy. High NLR level were correlated with poor pathological response and DFS in neoadjuvant chemotherapy or combined with PD-1 checkpoint inhibitors group. Multivariate analysis revealed that baseline NLR could independently predict pathological response and DFS in the neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group. Conclusion High NLR level were correlated with poor pathological response and shorter DFS in patients with NSCLC undergoing neoadjuvant chemotherapy or combined with PD-1 checkpoint inhibitors. Meanwhile, baseline NLR could independently predict response to pathological response and DFS, revealing its potential as a screening tool in NSCLC patients who received neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Objective: To investigate the expression of glycosyltransferase enzyme 3 (GCNT3) in non-small cell lung cancer (NSCLC) tis-sues and corresponding normal tissues, and to further explore the relationship between GCNT3 expression and clinicopathological fea-tures, overall survival (OS), and progression-free survival (PFS) in patients with NSCLC. Methods: In this study, we used quantitative re-al-time polymerase chain reaction and Western blot to assess the mRNA and protein expression of GCNT3 in paired NSCLC and non-tu-mor tissues. In addition, 164 NSCLC patients were estimated for GCNT3 expression by immunohistochemistry, and the correlation be-tween GCNT3 expression and clinicopathological features was evaluated. Further, the effects of GCNT3 on the proliferation, invasion, and migration abilities of NSCLC cells were studied. Results: The mRNA and protein expression levels of GCNT3 in NSCLC tissues were both significantly higher than those in the corresponding non-tumor tissues. Among the 164 patients with NSCLC, high GCNT3 expres-sion was associated with gender, smoking, histology, pathological stage, and lymph node metastasis. Kaplan-Meier analysis displayed significant differences in OS and PFS among the groups exhibiting differences in GCNT3 expression (P<0.05). The NSCLC patients with increased GCNT3 expression showed poor OS and PFS. A multivariate analysis demonstrated that GCNT3 expression was as an inde-pendent prognostic factor for NSCLC (P<0.05). Cell function experiments showed that the proliferation, invasion, and migration abili-ties of NSCLC cells were significantly attenuated after inhibition of GCNT3 expression (P<0.05). Conclusions: High expression of GCNT3 was associated with unfavorable OS and PFS in patients with NSCLC; GCNT3 might, therefore, act as a prognostic biomarker for NSCLC.

Objective: To investigate the prehospital intervention based on emergency medical services (EMS) in patients with acute ischemic stroke (AIS) for door-to-needle time (DNT) with intravenous thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) impact. Methods: 112 emergency patients receiving rt-PA intravenous thrombolysis admitted to the First Hospital of Qinhuangdao City based on EMS from June 2016 to December 2017 were enrolled. According to whether or not to receive prehospital interventions, patients were divided into prehospital intervention group (n = 42) and routine treatment group (n = 70). Both groups followed the general principles of first aid, including assessment and support of the airway, respiration, and circulation, and blood glucose, electrocardiogram, and dynamic vital signs were monitored. Based on the general principle of EMS, first-aid personnel in the prehospital intervention group screened suspected acute stroke patients requiring prehospitalization according to Los Angeles prehospital stroke screening table (LAPSS), and established fluid ways, and got blood samples to evaluate rt-PA intravenous thrombolysis and risks. Factors influenced DNT compliance were analyzed through multivariate Logistic regression, which included the education level of the patient, whether there were risk factors related to cerebrovascular disease (hypertension, coronary heart disease, diabetes), visit time, National Institute of Health stroke scale (NIHSS) score, whether received EMS intervention or not. The average DNT, DNT ≤ 60 minutes compliance rate, communication time, and decision time for thrombolysis were compared between the two groups. NIHSS score was used to evaluate the effective rate of thrombolysis for 7 days. The modified Rankin score (mRs) was used to evaluate the neurological function after 3 months of thrombolysis (a mRs score of 0-2 was defined as a good nerve function). Results: Univariate analysis showed that the DNT of patients with NIHSS score > 5 was significantly shorter than those with NIHSS score≤5, and DNT in patients received EMS intervention was significantly shorter than the non-receiver; but education level, visiting time, and risk factors associated with cerebrovascular disease had nothing to do with DNT. Multivariate Logistic regression analysis showed that NIHSS score and EMS intervention were the influencing factors of DNT compliance [NIHSS score: odds ratio (OR) = 0.452, 95% confidence interval (95%CI) = 0.162-1.263, P = 0.030; EMS intervention: OR = 3.077, 95%CI = 1.260-7.514, P = 0.014]. Compared with conventional treatment group, DNT of intravenous thrombolytic in prehospital intervention group was significantly shortened (minutes: 62.00±11.07 vs. 78.03±21.04), DNT≤60 minutes compliance rate was significantly increased [35.7% (15/42) vs. 12.9% (9/70)], communication time [minutes: 4 (3, 6) vs. 6 (5, 9)] and decision-making thrombolytic time (minutes: 5.81±2.48 vs. 6.70±2.15) were significantly shortened, the differences were statistically significant (all P < 0.05). The 7-day effective rate in the prehospital intervention group [33.3% (14/42) vs. 14.3% (10/70), χ² = 5.657, P = 0.017] and the 3-mouth good rate of nerve function [38.1% (16/42) vs. 14.3% (10/70), χ² = 10.759, P = 0.001] were significantly higher than those in the conventional treatment group. Conclusion Prehospital interventions based on EMS can shorten DNT of intravenous thrombolysis in the patients with AIS, improve treatment efficiency, and improve prognosis.

OBJECTIVE: To study the effect of curcumin on the oxidative stress induced by nano-silicon dioxide( SiO_2) in A549 cells and to explore its potential mechanism. METHODS: A549 cells were randomly divided into 6 groups. Nano-SiO_2 group cells were stimulated with nano-SiO_2 solution with a final concentration of 20 mg/L; curcumin low-,medium-,and high-dose group cells were treated with curcumin at final concentrations of 5,10,and 20 μmol/L respectively and 20 mg/L nano-SiO_2 solution; the solvent control group was treated with dimethyl sulfoxide with a volume fraction of 0. 10%. The cells in the blank control group were not given any treatment. The cells in these 6 groups were incubated for 12 hours,and the level of malondialdehyde( MDA) and the activity of total superoxide dismutase( T-SOD) in the cells were measured by spectrophotometer. The relative expression of mRNA and protein of nuclear factor E2-associated factor 2( NRF2),thioredoxin-1( TRX1),and thioredoxin interaction protein( TXNIP) were analyzed by real-time fluorescent quantitative polymerase chain reaction and Western blot respectively. RESULTS: The MDA level in A549 cells of nano-SiO_2 group increased( P < 0. 05),the T-SOD activity decreased( P < 0. 05),and the mRNA and protein relative expression of NRF2 and TRX1 were up-regulated( P < 0. 05),TXNIP relative expression of mRNA and protein were down-regulated( P <0. 05),when compared with the blank control group and the solvent control group. After intervention with curcumin,with the increased of curcumin concentration,the MDA level in A549 cells decreased,the T-SOD activity increased,the relative expression of NRF2 mRNA and TRX1 mRNA and protein was up-regulated,the mRNA and protein relative expression of TXNIP was down-regulated,and showed a dose-dependent manner( P < 0. 01). CONCLUSION: Curcumin can protect nano-SiO_2-induced oxidative stress in A549 cells. It may activate TRX system by regulating NRF2/antioxidant response elements pathway,exerting an anti-oxidation effect and protecting cells from excessive oxidative damage.

Objective To retrospectively analyze the relationship between progression free survival (PFS) and overall survival (OS) in patients with non small cell lung cancer (NSCLC), and to detect the influence of plasma fibrinogen and D-dimer levels before treatment in the prognosis of advanced stage (stageⅢB-Ⅳ) of NSCLC. Methods The study comprised 134 NSCLC patients with clear pathological diagnosis. All patients were grouped by plasma fibrinogen and D-dimer levels before treatment. We set the normal values of fibrinogen as≤4 g/L and D-dimer as≤500μg/L(FEU). Patients with normal levels of fibrinogen and D-dimer were grouped into low risk group, patients with elevated fibrinogen or D-dimer were grouped into median risk group, and patients with both elevated values were grouped into high risk group. Chi-square test and one way ANOVA analysis were used to analyze the clinicopathologic features of different groups. The OS and PFS in different groups were analyzed by Kaplan-Meier analysis. Univariate analysis of PFS and OS were conducted. Then multivariate analysis was conducted with the Cox regression model in three groups. Results The clinicopathologic features showed no differences between different groups. There were significant differences in OS and PFS between high risk group and other groups. In the survival curves, the high risk group showed poor prognosis. The result of multivariate analysis showed that clinical stage (OS:RR=1.846, 95%CI 1.150-2.964,P=0.011; PFS:RR=1.762, 95%CI 1.190-2.609, P=0.005) and grouped by fibrinogen and D-dimer (OS:RR=1.415,95%CI 1.050-1.908,P=0.023;PFS:RR=1.373,95%CI 1.070-1.761,P=0.013) were prognostic factors for patients with NSCLC. Conclusion The plasma fibrinogen and D-dimer levels before treatment are closely related with the prognosis of NSCLC patients. And a high plasma fibrinogen and D-dimer levels before treatment are associated with poor prognosis in advanced stage of NSCLC patients.

Objective:To investigate the clinical characteristics of idiopathic hypereosinophilic syndrome (IHES) with gastrointestinal manifestations,and to improve the level of diagnosis and treatment of IHES. Methods:The clinical materials, process of diagnosis and treatment and prognosis of 9 patients diagnosed as IHES with gastrointestinal manifestations were retrospectively analyzed. Results:The average age of 9 patients was (22.66± 12.86)years old,and the ratio of male and female was about 1.25∶ 1. The main clinical manifestations included abdominal pain,diarrhea and abdominal distension.The eosinophil percentages in peripheral blood and bone marrow of the patients were (42.66 ± 19.88 )% and (39.33 + 15.99 )%, respectively.The ascites exudate cytology examination showed eosinophil infiltrated.The results of gastroscope or colonoscope showed mucosal hyperemia and edema,scattered bleeding spots, and dark red granular hyperplasia; the colon was affected frecuently.The histological biopsy confirmed that the mucosal was infiltrated by eosinophils.The abdominal CT of 6 patients showed that the walls of stomach or bowel were thickened.The abdominal symptoms disappeared,and the ascites was absorpted in 9 patients after the treatment of glucocorticoid.After 2 years of follow up,2 patients had relapse, others had no recurrence.Conclusion:Performing the routine diagnosis and treatment of gastrointestinal diseases, the clinicians should consider the possibility of IHES in order to avoid the misdiagnosis and delayed treatment. When IHES is diagnosed,steroid treatment should be performed in preference.
