Abstract
OBJECTIVE To study the characteristics of pulmonary function in children with pertussis-like coughing caused by different pathogen infections. METHODS The data on etiology and tidal breathing pulmonary function were collected from 95 hospitalized infants and young children with pertussis-like coughing. The tidal breathing pulmonary function was compared between these children and 67 healthy children. According to the type of pathogen, the children with pertussis-like coughing were classified to 6 groups: pertussis (n=17), viral infection (n=23), tuberculosis infection (n=6), Mycoplasma infection (n=9), other bacterial infection (n=8), and unknown pathogen (n=32). RESULTS Among the 95 children with pertussis-like coughing, 15 (16%) had mild obstructive ventilatory dysfunction, 30 (32%) had moderate obstructive ventilatory dysfunction, and 22 (23%) had severe obstructive ventilatory dysfunction. Compared with the normal control group, the children with pertussis-like coughing had significant reductions in inspiratory-to-expiratory time ratio, ratio of time to peak tidal expiratory flow to total expiratory time (tPF%tE), and ratio of volume to peak tidal expiratory flow to total expiratory volume (vPF%vE) (P<0.05). The tuberculosis infection and Mycoplasma infection groups had a significantly lower tidal volume than the normal control group (P<0.05). All pathogen infection groups except the tuberculosis infection group had significantly lower tPF%tE and vPF%vE than the normal control group (P<0.05). The pertussis group had significantly lower tPF%tE and vPF%vE than the other infection groups (P<0.05). CONCLUSIONS Most of children with pertussis-like coughing have abnormal pulmonary functions. The children with Bordetella pertussis infection have the most severe pulmonary function impairment. Tidal breathing pulmonary function test may provide a reference for pathogen analysis of children with pertussis-like coughing.

Abstract
OBJECTIVE To study the effect of intermittent versus daily inhalation of budesonide on pulmonary function and fractional exhaled nitric oxide (FeNO) in children with mild persistent asthma. METHODS A total of 120 children, aged 6-14 years, with mild persistent asthma who attended the hospital from January 2016 to January 2018 were enrolled. The children were divided into an intermittent inhalation group with 60 children (inhalation of budesonide 200 μg/day for 6 weeks when symptoms of asthma appeared) and a daily inhalation group with 60 children (continuous inhalation of budesonide 200 μg/day) by stratified randomization. The children were followed up at months 3, 6, 9, and 12 of treatment. The two groups were compared in terms of baseline data, changes in FeNO and pulmonary function parameters, amount of glucocorticoid used, number of asthma attacks, and asthma control. RESULTS At the start of treatment, there were no significant differences in baseline data, FeNO, and pulmonary function between the two groups (P>0.05). Over the time of treatment, FeNO gradually decreased and pulmonary function parameters were gradually improved in both groups (P<0.001). Compared with the intermittent inhalation group, the daily inhalation group had a better effect in reducing FeNO and increasing the predicted percentage of forced expiratory volume in 1 second (FEV1%pred) (P<0.001). The inhalation method and treatment time had an interaction effect on FeNO and pulmonary function parameters (P<0.001). In the daily inhalation group, FeNO and lung function parameters were improved rapidly and stabilized after 3 months of treatment, while those in the intermittent inhalation group stabilized after 6 months. After 12 months of treatment, there were no significant differences in the increases in body height and body weight and the degree of disease control between the two groups (P>0.05). Compared with the daily inhalation group, the intermittent inhalation group had a significantly lower amount of budesonide inhaled (P<0.05) and a significantly higher number of asthma attacks (P<0.05). CONCLUSIONS Intermittent inhalation and daily inhalation of budesonide can achieve the same level of asthma control in children with mild persistent asthma and both have no influence on the increases in body height and body weight. Daily inhalation of budesonide can produce a better efficiency in reduing FeNO and increasing FEV1%pred. Although intermittent inhalation can reduce the amount of glucocorticoid used, it may lead to a higher risk of asthma attacks.

Abstract
OBJECTIVE To study the changes in pulmonary function in infants and young children with Mycoplasma pneumoniae pneumonia (MPP). METHODS A total of 196 hospitalized children (at age of 0-36 months) who were diagnosed with MPP from January 2014 to June 2018 were enrolled as study subjects. A total of 208 children (at age of 0-36 months) with pneumonia not caused by Mycoplasma pneumoniae infection during the same period of time were enrolled as controls (non-MPP group). A retrospective analysis was performed for their clinical data. The two groups were compared in the pulmonary function on the next day after admission and on the day of discharge. The children with MPP were followed up to observe pulmonary function at weeks 2 and 4 after discharge. RESULTS Compared with the non-MPP group, the MPP group had significant reductions in the ratio of time to peak tidal expiratory flow to total expiratory time (TPTEF/TE), ratio of volume to peak tidal expiratory flow to total expiratory volume (VPTEF/VE), inspiratory-to-expiratory time ratio, and tidal expiratory flow at 25% remaining expiration on the next day after admission and on the day of discharge (P<0.05). In addition there were significant increases in the ratio of peak tidal expiratory flow to tidal expiratory flow at 25% remaining expiration, respiratory rate, effective airway resistance, and plethysmographic functional residual capacity per kilogram (P<0.05). Compared with the normal reference values of pulmonary function parameters, both groups had reductions in VPTEF/VE and TPTEF/TE on the next day after admission; on the day of discharge, the MPP group still had reductions in VPTEF/VE and TPTEF/TE, while the non-MPP group had normal values. The MPP group had increases in VPTEF/VE and TPTEF/TE from the day of discharge to weeks 2 and 4 after discharge (P<0.05), but TPTEF/TE still did not reach the normal value at week 4 after discharge. CONCLUSIONS Airway obstruction is observed in infants and young children with acute MPP or non-MPP, and the children with MPP have a higher severity of airway obstruction and a longer time for improvement, with a certain degree of airway limitation in the recovery stage.

Abstract
OBJECTIVE To study the effect of bronchopulmonary dysplasia (BPD) on lung function in preterm infants. METHODS According to the presence/absence or the severity of BPD, 72 preterm infants were divided into non-BPD group (n=44), mild BPD group (n=15) and moderate BPD group (n=13). Lung function was assessed by plethysmography on days 7, 14 and 28 after birth. RESULTS The preterm infants in the three groups had gradual increases in tidal volume per kilogram (TV/kg), functional residual capacity (FRC), ratio of time to peak tidal expiratory flow to total expiratory time (%T-PF) and ratio of volume to peak tidal expiratory flow to total expiratory volume (%V-PF) on days 7, 14 and 28 after birth, while there were gradual reductions in effective airway resistance per kilogram (Reff/kg) and respiratory rate (RR) (P<0.05). Compared with the non-BPD group on days 7, 14 and 28 after birth, the mild and moderate BPD groups had significantly lower TV/kg, FRC, %T-PF, and %V-PF and significantly higher Reff/kg and RR (P<0.05). On day 7 after birth, the moderate BPD group had significantly higher airway resistance, Reff/kg and FRC/kg than the mild BPD group (P<0.05). CONCLUSIONS There is a certain degree of pulmonary function impairment in preterm infants with BPD. Dynamic monitoring of lung function by plethysmography is useful for assessing lung development in the neonatal period in these infants.

Abstract
OBJECTIVE To explore the effects of low-level long-term occupational exposure to chromate on the health of workers, and the potential biomarkers of early health effects in terms of lung function, immune toxicity and genetic damage. METHODS A total of 22 chromate contact workers and 44 non-chromate contact workers from an electroplating enterprise with long-term occupational environment monitoring in line with the national standards in Inner Mongolia were investigated. The questionnaire survey was conducted to collect the basic situation, the history of smoking, drinking, diseases and so on. The portable lung function instrument, inductively coupled plasma mass spectrometry and cytokinesis-blocked micronucleus test were performed to measure the chromate contact workers'lung function, whole blood Cr (WB-Cr) and micronuclei frequency (MNF) of peripheral blood lymphocytes respectively. The cytometric bead array was used to detect the levels of IL-1β, IL-6, IL-8, IL-10, IL-12P70 and TNFα in the serum among the two groups. The effects of chromate exposure on the above-mentioned indexes involved biological exposure, lung function, immune response and genetic damage, and their correlation were analyzed with different statistical methods. RESULTS (1) the average length of service for chromate contact workers was 31 years, and their concentration of WB-Cr was 1.11-4.19 μg/L. They were divided into high and low exposure groups according to the median of 1.72 μg/L. The WB-Cr in the high exposure group (2.17 μg/L) was higher than that in the low exposure group (1.58 μg/L) as well as the reference value of the healthy population (1.74 μg/L, P<0.05); (2) the lung function test showed 10 (45.45%) chromate exposure workers had single or multiple abnormal lung function indexes, among which large airway injury index PEF, and small airway injury indexes MVV and FEF25%-75% were all negatively correlated with WB-Cr (r=-0.53, P<0.05; r=-0.52, P<0.05; r=-0.44, P<0.05); (3) IL-1β, IL-6, IL-8 and TNFα in the serum of chromate contact workers were higher than those in the control group (P<0.05), and there was a positive correlation between TNFα and WB-Cr, and among these cytokines (P<0.05); (4) the average lymphocyte MNF in chromate contact workers was 1.341%, higher than the reference value of the general population (0.436%, P<0.01). Poisson regression analysis showed MNF in thehigh exposure group was higher than that in the low exposure group, OR (95%CI) =1.323 (1.049, 1.669); (5) multiple linear regression analysis showed that the lung function index FEF25%-75% decreased with the increase of TNFα (P<0.05), no significant correlation was found between other cytokines, MNF and lung function indexes. CONCLUSION Long-term low-level occupational exposure to chromate can cause the decline of lung function, immune inflammatory reaction and genetic damage in workers, in which local or systemic inflammatory response is associated with decreased lung function. Lung function indexes PEF, FEF25%-75% and MVV, serum cytokines IL-1β, IL-6, IL-8, and TNFα, and peripheral blood lymphocyte MNF may be used as early health effects biomarkers of chromate exposure.

Abstract
OBJECTIVE To study the association of blood lipids with the development, clinical stage, allergic condition, and pulmonary function of asthma. METHODS A total of 56 children with asthma who attended the hospital between October 2016 and March 2017 were enrolled as the asthma group, and 46 children who underwent physical examination as the healthy control group. According to the clinical manifestations, the children with asthma were divided into acute exacerbation group (n=24) and chronic persistent group (n=32). According to the results of skin prick test (SPT) and serum IgE measurement, the children with asthma were divided into non-allergic asthma group (n=16) and allergic asthma group (n=38). Fasting blood lipid levels were measured in both asthma and control groups. Pulmonary function tests were performed for asthmatic children. RESULTS There were no significant differences in blood lipid levels between the asthma and control groups (P>0.05). The acute exacerbation group had significantly lower serum levels of high-density lipoprotein (HDL) and total cholesterol compared with the control group and the chronic persistent group (P<0.05). The allergic asthma group had a significantly lower serum HDL level than the non-allergic asthma group (P<0.05). In asthmatic children aged 6-13 years, the ratios of the measured values to the predicted values for forced vital capacity, peak expiratory flow, and maximal expiratory flow at 50% of vital capacity had a linear regression relationship with HDL and were positively correlated with HDL (P<0.05). Forced expiratory volume in one second and maximal mid-expiratory flow had a linear regression relationship with both HDL and LDL and were positively correlated with them (P<0.05). CONCLUSIONS Blood lipids are associated with the clinical stage, allergic condition, and lung function of childhood asthma. This indicates that blood lipids may be involved in several aspects of the pathogenesis of childhood asthma.

Abstract
OBJECTIVE To study the association of vitamin D level with asthma control and pulmonary function in children with asthma. METHODS A total of 150 children with asthma were enrolled as observation group, and 55 healthy children were enrolled as control group. According to the level of asthma control, the children were divided into good control group, partial control group, and non-control group. Chemiluminescence microparticle immunoassay was used to measure the serum level of 25-hydroxyvitamin D [25(OH)D] for all groups. According to the level of 25(OH)D, the asthmatic children were divided into normal vitamin D group, vitamin D insufficiency group, and vitamin D deficiency group. Pulmonary function was measured for all asthmatic children. RESULTS The observation group had a significantly lower serum level of 25(OH)D than the control group (25± 7 ng/mL vs 29± 4 ng/mL; P<0.05). The normal vitamin D group had the highest asthma control rate, followed by the vitamin D insufficiency group and the vitamin D deficiency group (P<0.05). There was no significant difference in pulmonary function among the three groups (P>0.05). CONCLUSIONS Asthmatic children have a lower serum level of 25(OH)D than healthy children. The serum level of 25(OH)D is associated with the level of asthma control and has no association with pulmonary function.

Abstract
OBJECTIVE To study the protective effect of dexmedetomidine against perioperative inflammation and on pulmonary function in patients undergoing radical resection of lung cancer. METHODS From May, 2014 to May, 2016, 124 patients with lung cancer receiving radical surgeries were randomized into experimental group (n=62) and control group (n=62). The patients in the control group received a single anesthetic agent for anesthesia, and additional dexmedetomidine was given in the experimental group. The levels of serum interleukin-1β (IL-1β), IL-10, and tumor necrosis factor-alpha (TNF-α) were measured before the operation (T0), at 30 min (T1) and 60 min (T2) during one lung ventilation (OLV) and at the end of operation (T3). Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of malondialdehyde (MDA), myeloperoxidase (MPO) and xanthine oxidase (XOD), and the arterial oxygen partial pressure (PaO2), oxygenation index (OI), airway plateau pressure (APP) and airway resistance (AR) were also recorded. RESULTS At the time points of T1 and T2, IL-1β, IL-10, MDA, MPO, TNF-α, and XOD levels were significantly increased in both of the groups, but the levels of IL-1, IL-10, TNF-α and MDA were significantly lower and MPO and XOD levels significantly higher in the experimental group than in the control group (P<0.05). In both groups, PaO2 and OI decreased and APP and AR increased significantly at T1 and T2, but APP and AR were significantly lower and PaO2 and OI significantly higher in the experimental group than in the control group (P<0.05). CONCLUSION Anesthesia with dexmedetomidine in lung cancer patients undergoing radical surgery can effectively reduce the inflammatory response of the lungs and protect the lung function of the patients.

Abstract
OBJECTIVE To study the effect of obesity on pulmonary function in newly diagnosed asthmatic children of different age groups. METHODS Two hundred and ninety-four children with newly diagnosed asthma were classified into preschool-age (<6 years) and school-age (6 to 12.5 years) groups. They were then classified into obese, overweight, and normal-weight subgroups based on their body mass index (BMI). All the children underwent pulmonary function tests, including large airway function tests [forced vital capacity (FVC%) and forced expiratory volume in one second (FEV1%)] and small airway function tests [maximal expiratory flow at 25% of vital capacity (MEF25%), maximal expiratory flow at 50% of vital capacity (MEF50%), and maximal expiratory flow at 75% of vital capacity (MEF75%)]. RESULTS The school-age group showed lower FEV1%, MEF25%, and MEF50% than the preschool-age group (P<0.05) after adjustment for sex and BMI. The normal-weight children in the school-age group had lower FEV1%, MEF25%, and MEF50% compared with their counterparts in the preschool-age group (P<0.05). The overweight children in the school-age group showed lower FVC% and MEF50% than those in the preschool-age group. However, all the pulmonary function parameters showed no significant differences between the obese children in the preschool-age and school-age groups. In the preschool-age group, FVC%, FEV1%, and MEF75% of the obese children were lower than those of the normal-weight children. In the school-age group, only FVC% and FEV1% showed differences between the obese and normal-weight children (P<0.05). CONCLUSIONS The effect of obesity on the pulmonary function varies with age in children with asthma, and the effect is more obvious in those of preschool age.

Abstract
OBJECTIVE To investigate the changes of pulmonary function and fractional exhaled nitric oxide (FeNO) in the standardized treatment of bronchial asthma in children. METHODS A total of 254 children who were newly diagnosed with acute exacerbation of bronchial asthma were selected as asthma group, and they were divided into two subgroups: asthma with concurrent rhinitis and asthma without concurrent rhinitis. All patients received the standardized management and treatment for one year. The pulmonary function parameters included forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), maximal mid-expiratory flow (MMEF), and mid-expiratory flow at 25%, 50%, and 75% of vital capacity (MEF25, MEF50, and MEF75). The FeNO levels were measured before treatment and at 3, 6, 9, and 12 months after treatment. Another 62 healthy children were selected as the control group, and the pulmonary function and FeNO levels were measured only once. RESULTS During one year of standardized treatment, FEV1, PEF, MMEF, MEF25, MEF50, and MEF75 gradually increased, and FeNO levels gradually decreased (P<0.05). Indicators of large airway function, such as FEV1 and PEF, almost returned to normal after 6 months of treatment; indicators of small airway function, such as MMEF, MEF25, MEF50, and MEF75 almost returned to normal after 9 months of treatment; there were no significant differences in the above indices between the asthma group and the control group after one year of treatment (P>0.05). However, the asthma group had a significantly higher FeNO levels than the control group after one year of treatment (P<0.05). The asthmatic patients with concurrent rhinitis had significantly higher FeNO levels than those without concurrent rhinitis before treatment and 3 months after treatment (P<0.05). Before treatment, there was a significant negative correlation between FeNO levels and pulmonary function parameters (P<0.05). CONCLUSIONS With the standardized treatment of bronchial asthma in children, pulmonary function parameters gradually increase and FeNO levels gradually decrease. The recovery of large airway function occurs earlier than the recovery of small airway function. Furthermore, the effect of rhinitis on airway responsiveness should be noted.

Abstract
OBJECTIVE To investigate the effect of air pollution on respiratory health in school-aged children in the main urban area of Chongqing, China. METHODS The main urban area of Chongqing was divided into polluted area and clean area according to the air pollution data shown on the Environmental Protection Agency Website of Chongqing between 2010 and 2015. A cluster sampling method was used to select 695 third- or fourth-grade children from 2 primary schools in the clean or polluted area as study subjects, with 313 children from the clean area and 382 children from the polluted area. Pulmonary function was examined for all children and a standard American epidemiological questionnaire (ATS-DLD-78-C) was used to investigate the prevalence of respiratory diseases and symptoms. RESULTS Compared with the clean area, the polluted area had significantly higher concentrations of inhalable particles (PM10), fine particulate matter (PM2.5), and nitric oxide (NOX) (P<0.05). The multivariate logistic regression analysis was performed after adjustment for confounding factors, and the results showed that compared with those in the clean area, the children in the polluted area had significantly higher risks of cough (OR=1.644), cough during cold (OR=1.596), expectoration during cold (OR=2.196), persistent expectoration (OR=1.802), and wheezing (OR=2.415). The boys and girls in the clean area had significantly higher forced vital capacity and forced expiratory volume in one second than those in the polluted area (P<0.05). CONCLUSIONS Air pollution in the main urban area of Chongqing is associated with the increased prevalence of respiratory symptoms in school-aged children and has certain effect on children's pulmonary function.

The boys and girls in the clean area had significantly higher forced vital capacity and forced expiratory volume in one second than those in the polluted area (P<0.05). CONCLUSIONS Air pollution in the main urban area of Chongqing is associated with the increased prevalence of respiratory symptoms in school-aged children and has certain effect on children's pulmonary function.

Abstract
Bronchial asthma is a heterogeneous disease that is characterized by airway hyperresponsiveness and chronic inflammation. It is often accompanied by reversible airflow obstruction. Current laboratory testing methods for the diagnosis of asthma in children mainly include lung ventilation function test. Due to the non-cooperation of children, it is very challenging to conduct lung ventilation function test for preschoolers. Lung function testing is an instantaneous indicator, which is influenced by the children's understanding ability and mental factors. In addition, it could not assess the severity of airway inflammation. Fractional exhaled nitric oxide (FeNO) is a noninvasive, simple, and objective indicator of airway inflammation and has gradually gained increased use in children in recent years. This review article introduces the source of FeNO, the reference value of FeNO in laboratory testing, and the progress in the application of FeNO in the diagnosis, prediction, and treatment of asthma in children of various ages.

Abstract
OBJECTIVE To study the expression profiles of PI3K, NF-κB, and STAT1 in peripheral blood mononuclear cells (PBMCs) in children with bronchial asthma, as well as their roles in the pathogenesis of asthma. METHODS Thirty children with acute exacerbation of bronchial asthma were enrolled as the asthma group, and 20 healthy children were enrolled as the control group. RT-PCR and Western blot were used to measure the mRNA and protein expression levels of PI3K, NF-κB, and STAT1 in PBMCs. A spirometer was used to compare the pulmonary function between the two groups. The correlations between the mRNA expression of PI3K, NF-κB, and STAT1 and pulmonary function in children with bronchial asthma were analyzed. RESULTS The asthma group had significantly higher mRNA and protein expression levels of PI3K, NF-κB, and STAT1 than the control group (P<0.05). Compared with the control group, the asthma group showed significant reductions in pulmonary function indices such as FEV1%, FEV1/FVC, and PEF% (P<0.05). In children with bronchial asthma, the mRNA expression levels of PI3K, NF-κB, and STAT1 were negatively correlated with FEV1%, FEV1/FVC, and PEF% (P<0.05). CONCLUSIONS The expression levels of PI3K, NF-κB, and STAT1 increase in children with asthma, and are negatively correlated with pulmonary function indices, suggesting that PI3K, NF-κB and STAT1 are involved in the development and progression of bronchial asthma in children.

Abstract
OBJECTIVE To investigate the effect of caffeine citrate treatment on early pulmonary function in preterm infants with apnea. METHODS Forty preterm infants with apnea were randomly divided into aminophylline treatment group (20 infants) and caffeine citrate treatment group (20 infants). When the preterm infants experienced apnea after birth, they were given aminophylline or caffeine citrate in addition to assisted ventilation with continuous positive airway pressure (NCPAP). After drug discontinuation, pulmonary function was measured and compared between the two groups. RESULTS After treatment, compared with the aminophylline treatment group, the caffeine citrate treatment group had significantly higher tidal volume, minute ventilation volume, ratio of time to peak tidal expiratory flow to total expiratory time, ratio of volume to peak tidal expiratory flow to total expiratory volume, peak expiratory flow, and breathing flow at 75%, 50%, and 25% of tidal volume (P<0.05). The caffeine citrate treatment group had a significantly shorter time of oxygen use and NCPAP support than the aminophylline treatment group (P<0.01). Compared with the aminophylline treatment group, the caffeine citrate treatment group had a significantly lower frequency of apnea attacks (P<0.01). CONCLUSIONS In the treatment of apnea in preterm infants, caffeine citrate can improve early pulmonary function and reduce the incidence of apnea.

Abstract
OBJECTIVE To investigate the effects of obesity on response to therapy and pulmonary function in children with asthma who receive inhaled corticosteroid (ICS) treatment. METHODS A total of 129 children with asthma were divided into two groups according to their body mass index: normal weight group (n=64) and obese group (n=65). The asthma control status and pulmonary function were compared between the two groups after one year of ICS treatment. The pulmonary function was expressed as percent forced expiratory volume in 1 second (FEV1%), percent predicted forced vital capacity (FVC%), peak expiratory flow (PEF), peak expiratory flow at 25% of vital capacity (PEF25), and peak expiratory flow at 50% of vital capacity (PEF50). The asthma control status was expressed as complete control rate, partial control rate, and uncontrolled rate. Sixty-eight healthy children were selected as the healthy control group. RESULTS There were significant differences in the indices of pulmonary function between the three groups before treatment (P<0.01); the healthy control group had the best values of pulmonary function, while the obese group had the worst values. After 1 year of treatment, the normal weight group showed significantly more improvements in FEV1% and FVC% than the obese group (P<0.01). However, there were no significant differences in improvements in PEF, PEF25, and PEF50 between the two groups. The complete control rate, partial control rate, and uncontrolled rate in the normal weight group were 72%, 19%, and 9%, respectively, while the rates in the obese group were 28%, 51%, and 22%, respectively; the normal weight group had a significantly better asthma control status than the obese group (P<0.01). CONCLUSIONS The asthmatic children with obesity have a significantly less improvement in large airway function and a poorer asthma control status after ICS treatment than those with the normal weight.
