Objective To observe the value of serum soluble receptor of advanced glycation endproducts (sRAGE) combined with lung function and high resolution lung CT (HRCT) in predicting the risk of chronic obstructive pulmonary disease (COPD) developing non-small cell lung cancer (NSCLC). Methods From January 2019 to June 2021, 140 patients with COPD combined with NSCLC, 137 patients with COPD, and 133 patients with NSCLC were enrolled in the study from the People's Hospital of Ningxia Hui Autonomous Region. General data, clinical symptoms, pulmonary function indexes and HRCT emphysema indexes (EI) were collected. Serum sRAGE levels of these patients were measured by enzyme linked immunosorbent assay. Clinical characteristics of patients with COPD complicated with NSCLC were analyzed. Serum sRAGE, lung function and lung HRCT were combined to evaluate the correlation between the degree of emphysema and the occurrence of NSCLC in COPD, and receiver operator characteristic (ROC) curve analysis was performed for diagnostic efficiency. Results Compared with NSCLC group, COPD combined with NSCLC group had higher proportion of male patients, higher proportion of elderly patients, higher smoking index, and higher proportion of squamous cell carcinoma (P<0.05). FEV1 and FEV1%pred in COPD combined with NSCLC group were significantly lower than those in COPD group and NSCLC group. The Goddard score and EI values of emphysema were significantly increased (P<0.05). Serum sRAGE was significantly lower than that of COPD group and NSCLC group (P<0.05). Serum sRAGE level was positively correlated with FEV1%pred (r=0.366, P<0.001) and FEV1/FVC (r=0.419, P<0.001), and negatively correlated with Goddard score (r=–0.710, P=0.001) and EI value (r=–0.515, P<0.001). Binary multi-factor logistic regression analysis showed that age, smoking index, EI, Goddard score, RV/TLC were positively correlated with the risk of COPD developing NSCLC, while FEV1%pred, FVC, FEV1/FVC and serum sRAGE were negatively correlated with the risk of COPD developing NSCLC. ROC curve results showed that the area under the curve (AUC) of single diagnosis of sRAGE was 0.990, and the optimal cut-off value of 391.98 pg/mL with sensitivity of 93.3% and specificity of 89.7%. The AUC of sRAGE combined with age, smoking index, EI, Goddard score, FEV1%pred, FVC, FEV1/FVC, RV/TLC was 1.000 with sensitivity of 96.7%, specificity of 96.6%, and Yoden index of 0.933. Conclusion The combination of serum sRAGE, lung function and HRCT emphysema score can improve prediction of NSCLC occurrence in COPD.
ObjectiveTo investigate the efficacy of Orem's self-care model in school-age children with asthma. MethodsSeventy-four children with asthma treated between March 2012 and June 2014 were divided into observation group (n=37) and control group (n=37) randomly. Orem's self-care model was applied in the observation group, while routine nursing was carried out in the control group. We observed the pulmonary function, therapeutic compliance and quality of life in children of both the two groups before and one year after treatment. ResultsOne year after treatment, forced expiratory volume in one second and peak expiratory flow increased significantly (P<0.05), and increase in the observation group was significantly more than that in the control group (P<0.05). Compared with the control group, the observation group showed significant increased treatment compliance rate (P<0.05). Pediatric asthma quality of life questionare scale results showed that one year after treatment, the two groups got significantly increased scores in the dimensions of emotion, symptom and activity (P<0.05), and the scores were significantly higher in the observation group (P<0.05). ConclusionOrem's self-care model has a significant curative effect for the improvement of lung function in school-age children with asthma, which can promot the treatment compliance and quality of life of the patients.

Objective To evaluate the effect of cardiopulmonary bypass （CPB） on pulmonary function in infants with variable pulmonary arterial pressure resulting from congenital ventricular septal defect （VSD）. Methods Twenty infants with VSD underwent corrective surgery were divided into pulmonary hypertension group （n= 10） and non-pulmonary hypertension group （n= 10） according to with pulmonary hypertension or not. Pulmonary function was measured before CPB , 3h,6h,9h,12h,15h,18h,21h, and 24h after CPB and duration for mechanical ventilation and cardiac intensive care unit stay were recorded. Results Pulmonary function parameters before CPB in nonpulmonary hypertension group were superior to those in pulmonary hypertension group （P〈0.01）, and pulmonary function parameters after CPB deteriorated than those before CPB （P〈0.05）, especially 9h,12h and 15h after CPB （P〈0.01）. Compared to pulmonary function parameters before CPB, pulmonary function parameters of pulmonary hypertension group at 3h after CPB were improved （P〉0.05）, but they deteriorated at 9h,12h and 15h after CPB （P〈0. 05）. Pulmonary function parameters at 21h and 24h after CPB was recoverd to those before CPB in two groups. Conclusions Although exposure to CPB affects pulmonary function after VSD repair in infants, the benefits of the surgical correction to patients with pulmonary hypertension outweigh the negative effects of CPB on pulmonary function. Improvement of cardiac function can avoid the nadir of pulmonary function decreasing. The infants with pulmonary hypertension will be weaned off from mechanical ventilator as soon as possible, if hemodynamics is stable, without the responsive pulmonary hypertension or pulmonary hypertension crisis after operation.
Objective To analyze the effects of different surgical methods on postoperative pulmonary function and exercise capacity in patients with non-small cell lung cancer (NSCLC), so as to explore whether it can effectively improve pulmonary function and promote the recovery of exercise capacity by reducing the number of trocars ports and the resection of normal lung tissues. Methods The clinical data of NSCLC patients who underwent surgery in the First Affiliated Hospital of Hebei North University from January 2016 to June 2019 were collected retrospectively. According to the surgical methods, they were divided into three groups: single utility port video-assisted thoracic surgery (SP-VATS) segmentectomy group, SP-VATS lobectomy group and three port video-assisted thoracic surgery (TP-VATS) lobectomy group. The changes of pulmonary function [forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), maximal voluntary ventilation (MVV)] and 6-minute walking distance (6MWD) at different time points [1st day before the operation (T0); 3rd day (T1), 7th day (T2), 1st month (T3), 3rd month (T4), 6th month (T5) and 1st year (T6) after the operation] were compared among the three groups. Results A total of 342 patients were included, including 102 in SP-VATS segmentectomy group, 116 in SP-VATS lobectomy group and 124 in TP-VATS lobectomy group. Except for pathological type and TNM stage (P<0.05), there was no significant difference in general information, preoperative pulmonary function or 6MWD among the three groups (P>0.05). The pulmonary function and 6MWD of the three groups before and after operation were not affected by pathological type or TNM stage (P>0.05). Except at T6 time point (P>0.05), there were significant differences in postoperative pulmonary function and 6MWD among the three groups at T1-T5 time points (P<0.05). Intra group comparison of pulmonary function and 6MWD in the three groups showed that the operation had the least impact on patients in SP-VATS segmentectomy group with the fastest recovery, followed by SP-VATS lobectomy group, and SP-VATS lobectomy group was the worst. Conclusions Video-assisted thoracoscopic for NSCLC can improve pulmonary function and promote the recovery of exercise capacity by reducing the number of trocars ports and the resection of normal lung tissues. However, this advantage is mainly reflected in the early postoperative stage.
Abstract: Objective To investigate the clinical effect of using zerobalanced ultrafiltration on postoperative lung function of coronary artery bypass grafting (CABG) patients under cardiopulmonary bypass (CPB). Methods Forty coronary artery bypass grafting patients in the First Affiliated Hospital of China Medical University from June 2006 to December 2008 were enrolled in this study, and were divided into two groups based on different ultrafiltration procedures. Patients in the experimental group (n=20), 14 males and 6 females, with an age of 65.43±8.31 years, underwent zerobalanced ultrafiltration and conventional ultrafiltration after CPB was carried out. Patients in the control group (n=20), 15 males and 5 females, with an age of 66.51±7.62 years, only underwent conventional ultrafiltration after temperature restoration. Preoperative pulmonary function and arterial blood gas were tested routinely. Airway resistance (Raw), oxygenation index (OI) and alveolar arterial oxygen difference ［P(Aa)O2］ were measured at the following points: before CPB, at the end of CPB, 6 hours, and 12 hours after operation. Postoperative mechanical ventilation time was also recorded. Results There was no significantly statistical difference between the two groups of patients in pulmonary function and arterial blood gas indexes before operation, and Raw, OI and P(Aa)O2 before CPB (Pgt;0.05). Nevertheless, at the points of 6 hours and 12 hours after operation, Raw ［2.22±0.31 cm H2O/(L·s) vs. 2.94±0.42 cm H2O/(L·s), F=0.061, Plt;0.05; 1.89±0.51 cm H2O/(L·s) vs. 2.52±0.29 cm H2O/(L·s), F=0.096, Plt;0.05］ and P(Aa)O2 (86.74±7.63 mm Hg vs. 111.66±7.49 mm Hg, F=0.036, Plt;0.05; 74.82±5.67 mm Hg vs. 95.23±6.78 mm Hg, F=0.059, Plt;0.05) of patients in the experimental group were significantly lower than those of patients in the control group. At the same points, OI of patients in the experimental group was significantly higher than that of patients in the control group (384.33±30.67 vs. 324.63±31.22, F=0.033, Plt;0.05; 342.24±23.43 vs. 293.67±25.44, F=0.047, Plt;005). Ventilator support time of the experimental group was shorter than the control group (15.44±3.93 h vs. 20.68±5.77 h,Plt;0.05). Conclusion Zerobalanced ultrafiltration can improve pulmonary function after coronary artery bypass grafting and shorten postoperative mechanical ventilation time.
Objective To examine the effects of pulmonary rehabilitation training on pulmonary function in patients post-stroke. Methods We searched Cochrane Library, PubMed, ProQuest, Embase, China National Knowledge Infrastructure, Wangfang Database, Chinese Biomedical Database, and VIP Chinese Science and Technology Journal Database for randomized controlled trials of investigating the effects of pulmonary rehabilitation training on pulmonary function in stroke patients published before September 2018. The patients in the training group were treated with pulmonary rehabilitation, including respiratory muscle training, chest breathing, or abdominal breathing training, with or without respiratory training device. The patients in the control group received conventional stroke rehabilitation. The outcome indicators included forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1 percentage predicted (FEV1%pred), peak expiratory flow rate, maximal inspiratory pressure (PImax), maximal expiratory pressure, exercise endurance, and quality of life. Two researchers independently carried out literature retrieval and data extraction, using Physiotherapy Evidence Database scale, and standard data extraction forms adapted from Cochrane Collaboration model to evaluate the studies quality. The Meta-analysis was performed using Review Manager Version 5.3. Results Eleven studies met the study criteria with a total of 500 stroke patients, including 274 patients in the training group and 226 patients in the control group, respectively. The Meta-analysis showed that after pulmonary rehabilitation training, the values of FVC [mean difference (MD)=0.30 L, 95% confidence interval (CI)(0.26, 0.34) L, P<0.000 01], FEV1 [MD=0.28 L, 95%CI (0.25, 0.32) L, P<0.000 01], and 6-minute walking test [MD=43.43 m, 95%CI (7.92, 78.95) m, P=0.02] in the training group were significantly higher than those in the control group, as well as the change of PImax [MD=6.49 cm H2O (1 cm H2O=0.098 kPa), 95%CI (3.67, 9.32) cm H2O, P<0.000 1]. The advantages of pulmonary rehabilitation training had not been found in improving FEV1/FVC and FEV1%pred (P>0.05). Conclusions The implementation of pulmonary rehabilitation training in the way of respiratory muscle training combined with conventional rehabilitation therapy could improve two kinds of indicators of pulmonary function referring to FVC and FEV1, inspiratory muscle strength and 6-minute waking distance. The long-term effect of pulmonary rehabilitation training on stroke patients, the respiratory training mode of different prescriptions, the endurance of exercise and the quality of life need further study.
