Objective:Gastrointestinal heat retention syndrome(GHRS)is associated with lung-heat syndrome and is related to recurrent respiratory infection.Upper respiratory tract infection(URTI)lung heat syndrome is common in children.The study will explore the effect of GHRS on the structure and function of gut microbiota in children with URTI lung-heat syndrome.Methods:Participants were divided into both groups using the self-developed URTI scale and the“GHRS Diagnostic Scale$Pediatric Part”:GHRS-positive children(LS group)and GHRS-negative children(L group).General information,clinical symptoms,and stool were collected.We used 16S rRNA amplicon sequencing technology to determine the gene sequence of the V3eV4 region in feces and measure the gut microbiota of the both groups at the genus level.Results:A total of 23 children were included in the both groups.There were 12 cases in the LS group and 11 cases in the L group.There was no statistical difference between the both groups in age,gender,height,weight,and body mass index.The effective sequences shared by the both groups accounted for 85.66%of the total.In the gut microbiota,there was no difference in the a diversity and the b diversity between the both groups.Compared with the L group,the LS group had a significant increase in the relative abundance of the Ruminococcus gnavus group,Prevotella-9,Staphylococcus,and Actinomyces(P<.05).The functions of the both groups of microbiota primarily concentrate on metabolism,genetic information processing,and environmental information processing.The relative abundance of signaling molecules and interactions in the LS group were higher than that in the L group(P<.05).The redundancy analysis(RDA)showed that the URTI score had the greatest impact on the distribution of microbiota.Conclusion:GHRS may affect the development of URTI lung-heat syndrome by changing the relative abundances of gut microbiota. 展开更多

Objective:To explore the structural and functional characteristics of microbiota in oropharynx of subhealthy children with gastrointestinal heat retention syndrome(GHRS)differentiated by traditional Chinese medicine,and screen the biometric operational taxonomic units(OTUs)to assist the clinical diagnosis.Methods:We recruited children according to the“GHRS diagnostic scale”,collected their oropharyngeal swabs,and sequenced the 16 SrDNA V4 region.We described the bacterial structure with alpha-indexes,beta-distances,and relative abundances;moreover,we screened the differential genera/OTUs with Wilcoxon rank-sum test,Metagenome Seq analysis,and linear discriminant analysis effect size(LEf Se)analysis,in which biometric OTUs were selected to construct the receiver operating characteristic curve to verify the diagnostic value.The bacterial function was predicted with Kyoto Encyclopedia of Genes and Genomes pathways according to 16S rDNA gene by using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States.Results:The study population was composed of 10 children with GHRS and 10 healthy control children.GHRS children were more likely to overeat(gluttony,P=.033).Alpha-indexes,such as Sobs,abundancebased coverage estimator,Bootstrap,and Qstat,were significantly higher in the GHRS group,while betadistances did not exhibit any significant intergroup differences.There were 9 differently distributed nonpredominant genera between the groups in Wilcoxon rank-sum test,as well as 13 non-predominant genera in Metagenome Seq analysis and 3 non-predominant OTUs in LEfSe analysis.OTU44 and OTU196 were used to construct the receiver operating characteristic curve,and the area under curve was 0.92.Predicted functions showed that pathways related to oxidative phosphorylation and carbon metabolism were enriched in healthy control samples,while the pathway related to renin secretion was remarkably enriched in GHRS samples.Conclusion:Unique oropharyngeal microbial structure and function were identified in GHRS children.OTU44 and OTU196 were specific OTUs,which could be used as biomarkers of GHRS to assist clinical diagnosis. 展开更多

Objective:To explore the relationship between gastrointestinal heat retention syndrome and the incidence of pneumonia and recurrent respiratory tract infections(RRTIs)in children.Methods:A prospective cohort study was conducted in the pediatric outpatient department of Beijing Dongfang Hospital.Children without respiratory tract infections(RTIs)were consecutively recruited according to the selection criteria.A semi-structured questionnaire was used to record traditional Chinese medicine(TCM)symptoms and demographic and physiological characteristics.Gastrointestinal heat retention syndrome was considered to be a predisposing factor and was diagnosed according to a scale with reliability and validity.The participants were followed up for 12 months.Participants and their parents or guardians were contacted via clinical interviews and telephone every 6 months.Episodes of pneumonia and RTIs were recorded in detail.Results:A total of 420 children were included.Of participants,370(88.10%)were followed up for 12 months.The mean number of RTI episodes per participant was 5.37(95%CI:5.14 to 5.60).In total,186 participants in the gastrointestinal heat retention syndrome group and 184 participants in the nongastrointestinal heat retention syndrome group completed the 12-month follow-up period.The baseline of both groups was comparable.The incidence of RRTIs in children with gastrointestinal heat retention syndrome was 1.27(95%CI:1.01 to 1.59)times that in children without gastrointestinal heat retention syndrome.Logistic regression analysis revealed that abnormally increased appetite with frequent hunger,foul breath,dry stools,and dark red or purple fingerprints were positively correlated with the incidence of pneumonia.Irascibility and feverish feelings in the palms and soles were positively correlated with the occurrence of RRTI.Conclusions:Gastrointestinal heat retention syndrome is a risk factor for RRTIs in children.Studies with larger sample sizes and longer follow-up time are warranted to confirm the degree of causal risk associated with RTIs. 展开更多

Objective:To investigate the association between gastrointestinal heat retention syndrome(GHRS)and adult chronic eczema.Methods:This caseecontrol study compared GHRS/GHRS accompanied by damp-heat syndrome(GHRSDHS)and other patient characteristics between subjects with(cases)and without chronic eczema(controls)to identify potential factors associated with this condition.Semi-structured questionnaires were used to collect data via face-to-face interviews.Participants were recruited from Dongzhimen Hospital affiliated with Beijing University of Chinese Medicine.A logistic regression analysis was performed on the collected data,and odds ratios(ORs)were calculated.Results:A total of 168 cases and 172 controls were recruited.Among the cases of adult chronic eczema,there were 79 subjects with GHRS and 68 with GHRS-DHS.Sex(P=.02,OR=0.54,95%confidence interval[CI]:0.32-0.91),GHRS(P=.04,OR=1.90,95%CI:1.02-3.51),GHRS-DHS(P<.001,OR=4.89,95%CI:2.36-10.15),high sweet food consumption(P=.04,OR=2.03,95%CI:1.03-3.97),and mental stress(P=.01,OR=2.37,95%CI:1.26-4.47)were each found to be associated with chronic eczema.Furthermore,GHRS had a weak positive correlation with eczema EASI severity as measured by the eczema area and severity index(EASI)(P=003).Conclusion:GHRS/GHRS-DHS may be associated with adult chronic eczema.In the future,prospective cohort studies with larger samples should be conducted to investigate the cause and effect association between GHRS and adult chronic eczema. 展开更多

Objective:To explore the effect of Tanreqing Injection(痰热清注射液,TRQI) on the treatment of acute exacerbation of chronic obstructive pulmonary disease(AECOPD) with Chinese medicine syndrome of retention of phlegm and heat in Fei(痰热阻肺证,RPHF).Methods:In a prospective randomized controlled clinical trial,90 patients with AECOPD of RPHF syndrome were randomly assigned to 3 groups,TRQI and controls A and B,each with 30 cases.The TRQI group was administered with the intravenous injections of 20 mL TRQI once a day and conventional Western medicine treatment.Control group A was administered with the intravenous injection of 15 mg ambroxol hydrochloride twice a day and conventional Western medicine treatment,and control group B was administered with conventional Western medicine treatment only.The treatments were administered for 10 days.Chinese medical symptoms and signs were scored,and plasma concentrations of interleukin(IL)-8 and neutrophil elastase(NE) were recorded.Results:(1) The Chinese medical symptoms (cough,sputum amount,expectoration,dyspnea and fever) and signs(tongue and pulse) improved significantly in the TRQI group(P〈0.05 or P〈0.01),and improvements in cough,sputum amount and expectoration were better in the TRQI group than control group B(P〈0.05);there was no significant difference between the TRQI group and control group A(P〉0.05).The sign of tongue was also improved significantly in the TRQI group (P〈0.05).(2) The overall effects in the TRQI group and control group A were significantly better than in control group B(P〈0.05),with no significant differences between the TRQI group and control group A(P〉0.05).There was no significant difference in the total effective rate among the three groups(P〉0.05).(3) After treatment, the plasma concentrations of IL-8 and NE decreased in the TRQI group and control group A(P〈0.05),and the concentration of IL-8 in control group B decreased(P〈0.05).The difference in IL-8 was greater in the TRQI group than in control group A and B before and after treatment,and the change in NE was greater in control group A than in the TRQI group and control group B,but there was no statistical significance among the three groups with regards to the change in IL-8 or NE(P〉0.05).Conclusion:TRQI could improved the Chinese medical signs and symptoms in the patients with AECOPD,possibly because of the decreasing plasma levels of IL-8 and NE which could improve response to airway inflammation and mucus hypersecretion. 展开更多
