ABSTRACT

Objective@#To explore the consumption of sugar sweetened beverages (SSBs) and its association with behavioral problems in Chinese preschool children, and to provide a scientific basis for the prevention of behavioral problems of children.@*Methods@#A total of 7 634 children aged 3-6 years were chosen from kindergartens in 3 cities (Yangzhou, Xuzhou, Zhenjiang) in the lower reaches of Yangtze River using method of cluster sampling during October to November in 2017. Parental or guardian questionnaires were used to obtain information regarding child consumption of SSBs. The Strengths and Difficulties Questionnaire (SDQ) was used to assess children s emotional and behavioral problems. Multivariate Logistic regression model was used to explore the association between different SSBs intake frequency and children s behavioral problems.@*Results@#A total of 5 509(72.2%) consumed SSBs less than once a day, 830(10.9%) reported SSBs consumption once a day, and 1 295(16.9%) had 2 times or more intake of sugar sweetened beverages per day. After adjusting for confounding factors including age, sex, BMI, family financial status, parental education, screen time, sleep duration, and physical activities duration, multiple Logistic regression model revealed that intake of SSBs once a day was associated with an increased risk of hyperactivity disorder ( OR =1.26, 95% CI =1.01-1.57) and SDQ total difficulties ( OR =1.44, 95% CI =1.14-1.82) in boys and with an increased risk of emotional symptoms ( OR=1.34, 95%CI =1.02-1.76), conduct problems ( OR=1.53, 95%CI =1.18-2.00), hyperactivity disorder ( OR=1.79, 95%CI =1.42-2.27) and prosocial behavior ( OR=1.48, 95%CI =1.14-1.91) in girls. Intake of SSBs≥2 times per day was associated with an increased risk of emotional symptoms ( OR=1.28, 95%CI =1.02-1.59) and SDQ difficulties ( OR=1.30, 95%CI =1.07-1.58) in boys and not with behavioral problems in girls.@*Conclusion@#Sex differences are observed with respect to the association between SSBs intake and behavioral problems in preschoolers, but no significant dose response relationship was observed. More longitudinal studies are needed to further explore the association between SSBs intake and behavioral problems in preschool children as well as the underlying physiological mechanisms in future.

ABSTRACT

Objective To explore the different diagnostic values of acid-fast staining, tuberculosis culture, tuberculosis DNA detection (TB-DNA), tuberculosis RNA constant temperature amplification technology (SAT-TB) in the detection of Mycobacterium tuberculosis in sputum specimens. Methods A total of 200 pulmonary tuberculosis patients and 80 non-tuberculosis patients who were hospitalized in Hebei Chest Hospital between September 2015 and September 2019 were selected for this study. Sputum samples were collected after admission, and the detection values of acid-fast staining, tuberculosis culture, TB-DNA, and SAT-TB in sputum samples were statistically analyzed. Results The differences in the sensitivity, accuracy, positive predictive value, and negative predictive values of the four diagnostic methods of acid-fast staining, tuberculosis culture, TB-DNA, and SAT-TB were statistically significant (P TB-DNA> tuberculosis culture> acid-fast staining. In terms of the positive predictive value of diagnosis, the values of SAT-TB, TB-DNA, and tuberculosis culture were higher than that of acid-fast staining. The Kappa values of the four methods and the gold standard were: Kappa (acid-fast staining) = 0.145, Kappa (tuberculosis culture) = 0.395, Kappa (TB-DNA) = 0.602, and Kappa (SAT-TB) = 0.770. Conclusion The four diagnostic methods of acid-fast staining, tuberculosis culture, TB-DNA, and SAT-TB all had certain detection value with their advantages and disadvantages. SAT-TB was a better detection method with high specificity, good sensitivity, and a short detection timer, which could quickly identify bacteria and distinguish live bacteria.

ABSTRACT

Objective:To evaluate the inhibitory effect of a retinoid derivative ECPIRM on proliferation of a cutaneous T-cell lymphoma (CTCL) cell line HH, and to explore its potential mechanisms.Methods:Cultured HH cells were treated with ECPIRM at different concentrations of 0 (control group) , 5, 10 and 20 μmol/L separately for 72 hours, cell counting kit-8 (CCK8) assay was performed to evaluate the effect of ECPIRM on the proliferative activity of HH cells, and flow cytometry to investigate the effect of ECPIRM on apoptosis of HH cells. Some HH cells were treated with 10 μmol/L ECPIRM for 72 hours, transcriptome sequencing was performed to investigate gene expression changes triggered by ECPIRM in HH cells, and Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis and gene ontology (GO) enrichment analysis were then performed to analyze differentially expressed genes in HH cells induced by ECPIRM. Reverse transcription-qPCR was subsequently conducted to verify changes in key gene expression in related pathways. Intergroup differences were analyzed by using one-way analysis of variance, and least significant difference (LSD) - t test was used for multiple comparisons. Results:CCK8 assay showed that the 50% inhibitory concentration (IC50) of ECPIRM on HH cells was 4.91 ± 2.48 μmol/L, the viability of HH cells significantly differed among the control group, and 5-, 10-and 20-μmol/L ECPIRM groups (100.00% ± 2.87%, 49.58% ± 4.53%, 48.36% ± 2.88%, 31.44% ± 2.46%, respectively, F=162.86, P < 0.001) , and was significantly lower in the 5-, 10-and 20-μmol/L ECPIRM groups than in the control group ( t=15.36, 15.73, 20.89, respectively, all P < 0.001) . Flow cytometry showed that there was a significant difference in the apoptosis rate among the 4 groups (11.51% ± 1.84%, 23.83% ± 5.72%, 36.19% ± 8.33%, 49.75% ± 4.10%, respectively, F=17.62, P < 0.001) , and the 10-and 20-μmol/L groups showed significantly increased apoptosis rates compared with the control group ( t=4.46, 6.92 respectively, both P < 0.01) . Transcriptomics analysis revealed that the inhibitory effect of ECPIRM on the cellular proliferative activity may be related to the metabolic regulation of steroids. As reverse transcription-qPCR revealed, the 10-μmol/L ECPIRM group showed significantly decreased mRNA expression of L-amino acid oxidase (IL4I1) , acetyl-coenzyme A acetyltransferase 2 (ACAT2) , 3-hydroxy-3-methylglutaryl-coenzyme A synthase 1 (HMGCS1) , mevalonate diphosphate decarboxylase (MVD) , 3-β-hydroxysteroid-8,7-isomerase (EBP) , very low-density lipoprotein receptor (VLDLR) , 3-hydroxy 3-methylglutaryl-CoA reductase (HMGCR) compared with the control group (all P < 0.05) . Conclusion:The retinoid derivative ECPIRM exerted marked anti-proliferative and apoptosis-inducing effects on HH cells, which may be related to the decreased expression of key genes involved in steroid metabolism.

ABSTRACT

Drug resistance is a major obstacle in the development of effective colorectal cancer (CRC) therapy. Our study aimed to explore the reversal abilities of Jiedu Sangen decoction (JSD) on the 5-fluorouracil (5-FU) resistance and its underlying molecular mechanisms. Expression changes in HIF-1 of CRC tissues were firstly revealed by bioinformatics analysis. Afterwards, cell viabilities of JSD and 5-FU treatments on 5-FU resistant human colon cancer cells (HCT-8/5-FU) were determined. Expressions of phosphoinositide 3-kinase (PI3K), protein kinase B (AKT)/p-AKT, hypoxia-inducible factor 1 (HIF-1α), as well as glycolysis related proteins such as L-lactate dehydrogenase A (LDHA), Glucose transporter type 1 (Glut1), Hexokinase 2 (HKII), and cysteinyl aspartate specific proteinase (Caspase) family members in HCT-8/5-FU cells, HIF-1α silenced HCT-8/5-FU cells and tumor tissues were detected by western blotting. HIF-1α was found over expressed in CRC tissues according to public available datasets in Oncomine. Growth inhibition rates of HCT-8/5-FU cells were increased along with the increase of JSD concentrations. JSD caused down-regulated HIF-1α, PI3K, AKT/p-AKT, HKII and Glut1, as well as up-regulated Caspase3 and Caspase9 in HCT-8/5-FU cells and tumor tissues. In HIF-1α silenced HCT-8/5-FU cells, synergistic group showed significantly reduced expression levels of PI3K, AKT, p-AKT. Additionally, up-regulated expressions of Caspase6 and Caspase7 were observed. JSD combined with 5-FU also exhibited obvious inhibitory efficiency on tumor growth in vivo. JSD may reverse 5-FU resistance by suppressing glycolysis via PI3K/AKT/HIF-1α signaling pathway, thereby inhibiting glycolysis and induce apoptosis to enhance anti-tumor activity.

ABSTRACT

Solute carrier (SLC) transporters meditate many essential physiological functions, including nutrient uptake, ion influx/efflux, and waste disposal. In its protective role against tumors and infections, the mammalian immune system coordinates complex signals to support the proliferation, differentiation, and effector function of individual cell subsets. Recent research in this area has yielded surprising findings on the roles of solute carrier transporters, which were discovered to regulate lymphocyte signaling and control their differentiation, function, and fate by modulating diverse metabolic pathways and balanced levels of different metabolites. In this review, we present current information mainly on glucose transporters, amino-acid transporters, and metal ion transporters, which are critically important for mediating immune cell homeostasis in many different pathological conditions.

ABSTRACT

To explore changing trend in prognosis of primary hypopharyngeal carcinoma and to analyze the reasons at the Eye, Ear, Nose and Throat Hospital of Fudan University. We retrospectively analyzed the clinical data of 461 patients with primary hypopharyngeal carcinoma treated at the Eye, Ear, Nose and Throat Hospital of Fudan University from 2003 to 2007 (Group 1) and 2010 to 2014 (Group 2) according to the inclusion criteria. 142 from Group 1, including 133 males and 9 females, rangedfrom 38 to 82 years old and 319 from Group 2, including 313 males and 6 females, ranged from 39 to 81 years old, were included in this work. The laryngeal function preservation rate, survival outcome, application and effect of pre-and post-operative adjuvant therapy were compared. SPSS 24.0 was used for statistical analyses. There were 62 patients with early disease (T1-2N0) including 18 in Group 1 and 44 in Group 2, in whom 3 (16.7%) underwent surgical procedures with laryngeal function preservation in Group 1, while, 30 (68.2%) underwent laryngeal function preservation surgery in Group 2. The laryngeal function preservation rate showed an obviously upward trend in recent years (χ(2)=13.617, 0.001), whereas, the recurrence-free survival rate (RFS) and overall survival rate (OS) showed no significant differences between two groups (0.469 and 0.808, respectively). Among the 399 patients with advanced disease, 124 were in Group 1 and 275 in Group 2. After propensity score matching (PSM) was used, the OS rate was significantly higher for Group 2 than Group 1 (0.017), while the application of laryngeal function preservation surgery was significantly higher in Group 2 (χ(2)=4.686, 0.030). The application rates of preoperative adjuvant therapy and postoperative adjuvant chemotherapy were significantly higher in group 2 than in group 1 (χ(2)=5.687, 0.017; χ(2)=19.407, 0.001). The application of laryngeal function preserving surgery significantly increases the retention rate of laryngeal functions in patients with early-stage hypopharyngeal carcinoma, with similar long-term survival outcomes. The application of comprehensive treatment including preoperative adjuvant therapy and postoperative adjuvant treatments, especially postoperative chemoradiotherapy, shows an obvious increase in the function preservation rate and long-term survival in patients with advanced hypopharyngeal carcinoma.

ABSTRACT

The glycosylation heterogeneity of recombinant human pro-urokinase (pro-UK) was assessed using ultra-performance liquid chromatography-mass spectrometry (UPLC-MS). Firstly, the source of heterogeneity was determined by measuring the Mr of intact protein before and after N-deglycosylation. Glycosylation sites and the proportion of O-glycopeptides then were determined at the peptide level. Finally, the N-glycans were confirmed and quantified using the N-glycan profile. Results show that the structural heterogeneity of pro-UK is mainly caused by glycosylation. All T18 were fucosylated, and 6.4% of S138/139 was O-glycosylated with two kinds of oligosaccharides with a ratio of 6.0% and 0.4% respectively. All N302 positions were N-glycosylated by more than ten types of glycans, among which A2F and A3F accounted for 80% of the total. The assessment of glycosylation heterogeneity of pro-UK will provide a reference for quality standardization.

ABSTRACT

Purpose@#Central lymph node metastasis (CNM) are highly prevalent but hard to detect preoperatively in papillary thyroid carcinoma (PTC) patients, while the significance of prophylactic compartment central lymph node dissection (CLND) remains controversial as a treatment option. We aim to establish a nomogram assessing risks of CNM in PTC patients, and explore whether prophylactic CLND should be recommended. @*Materials and Methods@#One thousand four hundred thirty-eight patients from two clinical centers that underwent thyroidectomy with CLND for PTC within the period 2016–2019 were retrospectively analyzed. Univariate and multivariate analysis were performed to examine risk factors associated with CNM. A nomogram for predicting CNM was established, thereafter internally and externally validated. @*Results@#Seven variables were found to be significantly associated with CNM and were used to construct the model. These were as follows: thyroid capsular invasion, multifocality, creatinine > 70 μmol/L, age 1 cm, body mass index 1 ng/mL. The nomogram had good discrimination with a concordance index of 0.854 (95% confidence interval [CI], 0.843 to 0.867), supported by an external validation point estimate of 0.825 (95% CI, 0.793 to 0.857). A decision curve analysis was made to evaluate nomogram and ultrasonography for predicting CNM. @*Conclusion@#A validated nomogram utilizing readily available preoperative variables was developed to predict the probability of central lymph node metastases in patients presenting with PTC. This nomogram may help surgeons make appropriate surgical decisions in the management of PTC, especially in terms of whether prophylactic CLND is warranted.

ABSTRACT

OBJECTIVE: To observe improvement effects of fingolimod on middle cerebral artery occlusion/reperfusion (MCAO/R) injury model rats. METHODS: Male SD rats were randomly divided into sham operation group, model group and fingolimod low-dose, medium-dose and high-dose groups (0.5, 1, 2 mg/kg), with 8 rats in each group. Except for sham operation group, MCAO/R injury model was induced by suture-occluded method in other groups. Administration groups were given relevant medicine intragastrically after reperfusion [1 h after reperfusion (1st day), 22.5 h after reperfusion (2nd day), and then every 24 h until 142.5 h of reperfusion (7th day)]. Sham operation group and model group were given constant volume of normal saline intragastrically, once a day, for consecutive 7 d. The scores of neurological deficit and balance beam test, the times of memory error [work memory error (WME), reference memory error (RME) and total error] were recorded in each group. The contents of serum inflammatory cytokines (IL-6, IL-8, IL-10, TNF-α) were determined by ELISA, and triphenyl tetrazolium chloride staining method was used to detect the rate of cerebral infarction. RESULTS: Compared with sham operation group, neurological deficit scores (at different time points of 1st-7th day after administration), balance beam test scores (2nd, 4th, 7th day after administration), times of memory error (2nd, 4th, 7th day after administration), the contents of serum inflammatory cytokines and the rate of cerebral infarction were increased significantly in model group (P<0.05 or P<0.01). Compared with model group, neurological deficit scores (low-dose group at different time points of 3rd-7th day, medium-dose and high-dose groups at different time points of 2nd-7th day after administration), balance beam test scores (low-dose group at 7th day, medium-dose group at 4th and 7th day, high-dose group at 2nd, 4th, 7th day), RME times and total error times (low-dose group at 4th and 7th day, medium-dose group and high-dose group at 2nd, 4th, 7th day after administration), WME times (administrations groups at 7th day after administration), serum contents of IL-6, IL-8 and IL-10 (administrations groups), serum contents of TNF-α (medium-dose and high-does groups) and cerebral infarction rate (medium-dose and high-dose groups) were all decreased significantly (P<0.05 or P<0.01). CONCLUSIONS: Intragastric administration of fingolimod can significantly reduce neurological deficit score, balance beam test score and the times of memory error in MCAO/R injury model rats, and has a protective effect on cerebral tissue and memory function. These effects may be related to the down-regulation of inflammatory cytokines such as IL-6 and TNF-α by fingolimod.

ABSTRACT

Objective@#To determine the relationship between nodal disease distribution patterns and oncological outcome and optimum management of cN0/cN1 patients with hypopharyngeal squamous cell carcinoma (HPSCC).@*Methods@#The collected clinical data and the follow-up disease-free survival (DFS) information from 154 patients with HPSCC treated between 2001 and 2014 in Eye Ear Nose and Throat Hospital of Fudan University were retrospectively analyzed. Kaplan-Meier method was used to calculate DFS rate. Log-rank test and Cox regression model were performed to evaluate the survival prognostic factors for univariate and multivariate analyses.@*Results@#Among 154 patients (63 cN0 patients, 91 cN1 patients) with HPSCC,in whom 148 were male, 6 were female, with an arerage age of (58.6±9.9), 63 cN0 patients received lateral neck dissection, of whom 9 were histologically positive nodes. Particularly, occult metastasis rate was 15.6%(7/45) for HPSCC in pyriform sinus and 18.2%(2/11) for HPSCC in posterior pharyngeal wall. Among 91 cN1 HPSCC, 34 underwent radical neck dissection and 54 underwent selective neck dissection. DFS for patients(T3-4N1) with radical neck dissection was lower than that for patient with selective neck dissection(15.2% vs.39.5%, χ2=5.153, P<0.05). The DFS of cN0 HPSCC was overestimated by the false-negative patients (cN0→pN+) for cN0 HPSCC and the DFS of cN1 HPSCC was underestimated by the false-positive(cN1→pN0) for cN1 HPSCC.@*Conclusions@#For cN1 HPSCC, compared with radical neck dissection, selective neck dissection may be considered as a more adequate method for removal of metastatic lymph nodes. Postoperative combined therapy and follow-up strategy should be established according to pathological N staging.

ABSTRACT

Objective To investigate the effect of B-guided brachial plexus block anesthesia on postoperative cognitive function and serum neurotrophic factor (NGF) and transforming growth factor-β (TGF-β) levels in children with ulnar and radius fractures.Methods From February 2014 to January 2017,we selected 78 children with ulnar radius fractures in our hospital randomly and divided them into observation group and control group,each group 39 cases.The control group was given brachial plexus block anesthesia under the position of nerve stimulation,and the observation group was subjected to B-guided brachial plexus block anesthesia.Anesthesia-related indicators,anesthetic effects and complications were observed and analyzed between the two groups,and hemodynamics parameters of brachial plexus block after 0.5h,cognitive function and serum NGF and TGF-β levels before and after operation were compared.Results Compared with the control group,anesthesia onset,recovery room stay time in the observation group were shorter and the duration of analgesia was longer (P < 0.05).The excellent and good rate of anesthesia in the observation group 97.44% (38/39) was higher than that in the control group (76.92%,30/39).The incidence of complications in the observation group 5.12% (2/39) was much lower than that of the control group (23.08%,9/39,P < 0.05).There was no significant difference in systolic peak velocity between the two groups (P > 0.05).Compared with the control group,the end of the diastolic velocity and blood flow of brachial plexus block after 0.5h were higher,resistance and pulsatility index were lower (P < 0.05).There was no significant difference in preoperative cognitive function,serum NGF and TGF-β levels between the two groups before operation (P > 0.05).After operation,compared with the control group,the cognitive function,serum NGF and TGF-β levels were higher in the observation group (P < 0.05).Conclusion Anesthesia effect of B-guided brachial plexus block anesthesia is significant in children with ulnar radius fractures.The incidence of complications is low,which can significantly improve the ulnar arterial hemodynamics,significantly increased serum NGF,TGF-β levels,contribute to postoperative fracture healing,and will not affect the cognitive function of children after surgery.

ABSTRACT

BACKGROUND: Adiponectin is one of the adipocytokines that have been found to be negatively correlated with obesity in recent years. As an endogenous bioactive peptide, adiponectin is shown to be associated with insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and participate in the regulation of bone metabolism. OBJECTIVE: To describe the mechanism of adiponectin in bone metabolism, and mainly clarify the correlation of adiponectin with osteoblasts and osteoclasts. METHODS: The first author searched PubMed and CNKI databases for the articles addressing the experimental research and research progress of adiponectin in bone metabolism published from 2003 to 2017. The keywords were "adiponectin, osteoporosis, bone metabolism, osteogensis, bone absorption" in English and Chinese, respectively. Adiponectin, its receptors, bone metabolism, adiponectin effects on bone formation and bone resorption were reviewed. RESULTS AND CONCLUSION: Adiponectin exerts a comprehensive effect on bone metabolism, mainly through autocrine, paracrine and endocrine, insulin signaling pathways. Besides, it exerts biological effects mostly by regulating OPG/RANKL/RANK system, especially in bone formation and bone resorption. Therefore, adiponectin may prevent osteoporosis by regulating bone metabolism.

ABSTRACT

BACKGROUND: It is an urgent problem to effectively make bone marrow mesenchymal stem cells exert proper effects under hypoxic preconditioning. OBJECTIVE: To investigate the effects of diazoxide, a Mito-KATPchannel activator, on the proliferation and apoptosis of mouse BMSCs in hypoxic environment. METHODS: Mouse BMSCs were divided into four groups: blank control group, 0.16, 0.8, 4 μmol/L diazoxide groups. Cells intervened by diazoxide were cultured in a 10% O2incubator. MTT assay was performed to detect cell proliferation at 1, 2, 4, 6, 8 days after intervention, and Hoechst 33258 staining was performed to observe cell apoptosis at 14 days after intervention. RESULTS AND CONCLUSION: High homogeneity and purity but low proliferation of BMSCs was found. There was no significant difference in the activity of BMSCs among 0.16, 0.8, 4 μmol/L diazoxide groups (P > 0.05). In the blank control group, concentrated nuclei were dark blue in color and aggregated, and several round apoptotic bodies were found. In the diazoxide groups, apoptotic bodies were occasionally found, and no significant difference was found among different diazoxide groups. These findings indicate that a certain concentration of diazoxide can reduce cell apoptosis but has no effects on the proliferation of mouse BMSCs under hypoxic environment (10% O2).

ABSTRACT

Objective@#To evaluate the oncologic and functional outcomes of supracricoid partial laryngectomy (SCPL) in the treatment of laryngeal carcinoma.@*Methods@#A total of 298 laryngeal carcinoma patients who underwent SCPL treatment from January 2005 to December 2013 were reviewed retrospectively. Clinical data of demographic and clinical characteristics, postoperative complications, rehabilitation information, recurrence and metastasis were analysed. Survival and local control were used to evaluate the clinical outcome.Data were analyzed by SPSS 23.0 software.@*Results@#Thirty-one patients with supraglottic carcinoma underwent cricohyoidoepiglottopexy (CHEP)and 267 with glottic carcinoma underwent cricohyoidopexy (CHP) were enrolled in this study. The mean duration of followed up was 74 months, ranging from 12 to 146 months. Fifty-four cases died at last follow-up. With respect to 31 patients with supraglottic carcinoma, 5- and 10-year overall survival rates and disease specific survival rates all were 78.1%; 5- and 10-year disease free survival rates were 72.1% and 63.7% respectively; and 5- and 10-year local control rates were both 84.2%. In 267 patients with glottic carcinoma, 5- and 10-year overall survival rates were 85.8% and 77.1% respectively; 5- and 10-year disease specific survival rates were 86.6% and 78.4% respectively; 5- and 10-year disease free survival rates were 80.6% and 74.2% respectively; and 5- and 10-year local control rates were 90.0% and 89.4% respectively. The survival rate of patients with glottic carcinoma at stage T1 was higher than that at stage T2 or T3, and the disease free survival rate of patients with early stage was superior than that of patients with advance stage. Cox regression analysis showed that tumor stage T2, and T3, tumor recurrence, and tumor metastasis were independent risk factors for survival. Furthermore, nasogastric feeding tube removal rate was 100% and the decannulation rates of SCPL were 96% in the patients with SCPL.@*Conclusions@#SCPL is a safe procedure with tumor resection for laryngeal carcinoma, with preserving of swallowing, respiration, and phonation functions, and has excellent survival and local control rates. This procedure could be considered as a standard function-sparing treatment for selected patients with laryngeal carcinoma of stages T1b-T3.

ABSTRACT

The changes of endogenous metabolites in urine samples that come from pneumonia patients of 6 months to 6 years old children were analyzed by metabolomics methods based on gas chromatography and mass spectrometry (GC-MS).The aim of this study was to analyze and study the pathogenesis of endogenous metabolites in children with pneumonia and the pathogenesis of pneumonia susceptibility.The urine samples were collected and divided into normal children group (NC group,n=29),first infection with pneumonia group (FIP group,n=35),and repeated infection with pneumonia group (RIP group,n=31).The urine metabolic profile of pneumonia was obtained by GC-MS.Principal component analysis(PCA) and partial least squares-discriminant analysis (PLS-DA) were used to analyze the data.The results were analyzed by one-way analysis of variance and Fold change.Finally,there was significant difference between the normal group and the pneumonia group,the significant metabolites were serine,histidine,proline,norleucine,glutamine,stearic acid,valine,isoleucine with p value<0.05 and Fold change>5,and indole-3-acetic acid,creatine,ethanolamine,mannosylglycerol and fructose were significant between the two pneumonia groups with p value<0.05.The urinary metabolites demonstrated that amino acid metabolism and glucose metabolism were the main metabolic pathways and responsible for the susceptibility to pneumonia.
