[Objectives]To explore the clinical effect of Modified Gegen Qinlian Decoction combined with western medicine on children with rotavirus enteritis with damp-heat syndrome and its influence on myocardial enzymes.[Methods]One hundred and eighty children with rotavirus enteritis with damp-heat syndrome were randomly divided into control group and observation group,with 90 cases in each group.The control group was given western medicine symptomatic treatment,and the observation group was given Modified Gegen Qinlian Decoction treatment on the basis of the control group.Both groups were treated for 5 d.The clinical efficacy,symptom disappearance time,myocardial zymogram indicator level and TCM syndrome scores were compared between the two groups.[Results]After 5 d of treatment,the total effective rate of the observation group was 94.44%,which was significantly higher than that of the control group(84.44%)(P<0.05).The time of diarrhea,fever,vomiting,dehydration and fecal RV turning negative in the observation group were shorter than those in the control group,and the differences were statistically significant(P<0.05).After 5 d of treatment,the serum levels of creatine kinase(CK),creatine kinase isoenzyme(CK-MB),aspartate aminotransferase(AST),lactate dehydrogenase(LDH)and α-hydroxybutyrate dehydrogenase(α-HBDH)in the two groups were lower than those before treatment.The levels of the above five myocardial enzymes in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).After 5 d of treatment,the scores of defecation frequency,abdominal distention,thirst,dysphoria,fatigue and anorexia in the two groups were lower than those before treatment.The scores of the above five TCM syndromes in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).[Conclusions]Modified Gegen Qinlian Decoction combined with western medicine can quickly relieve the symptoms and signs of children with rotavirus enteritis with damp-heat syndrome,shorten the course of disease,and reduce myocardial injury.

Integrating proteomics and targeted metabolomics to reveal the material basis of liver-gallbladder damp-heat syndrome in chronic hepatitis B

Objective To elucidate the biological basis of liver-gallbladder damp-heat syndrome(LGDHS)within the framework of traditional Chinese medicine(TCM)as a complementary diagnostic and therapeutic approach in chronic hepatitis B(CHB).Methods CHB patients and healthy volunteers were enrolled from Shuguang Hospital Affili-ated to Shanghai University of Traditional Chinese Medicine between August 21,2018 and December 31,2020.They were divided into three groups:healthy group,LGDHS group,and latent syndrome(LP)group.Proteomic analysis using isobaric tags for relative and absolute quantitation(iTRAQ)was performed to identify differentially expressed proteins(DEPs).Metabolomic profiling via ultra-performance liquid chromatography-tandem mass spec-trometry(UPLC-MS/MS)was applied to serum samples to detect differentially regulated metabolites(DMs).Kyoto Encyclopedia of Genes and Genomes(KEGG)and Gene Ontology(GO)enrichment were employed to explore dysregulated pathways.Principal component analysis(PCA)and orthogonal partial least squares discriminant analysis(OPLS-DA)were utilized to visualize group separation and identify key metabolites and proteins contributing to LGDHS differentiation.Receiver operating characteristic(ROC)curve analysis evaluated the diagnostic performance of key biomarkers,while logistic regression models assessed their predictive accuracy.P values were corrected for multiple tests using the Benjamini-Hochberg method to control the false discovery rate(FDR).Validation of potential biomarkers was con-ducted using independent microarray data and real-time quantitative polymerase chain reac-tion(RT-qPCR).Results A total of 150 participants were enrolled,including healthy group(n=45),LGDHS group(n=60),and LP group(n=45).254 DEPs from proteomics data and 72 DMs from metabolomic profiling were identified by PCA and OPLS-DA.DEPs were mainly enriched in immune and complement pathways,while DMs involved in amino acid and energy metabolism.The integrated analysis identified seven key biomarkers:α1-acid glycoprotein(ORM1),asparagine synthetase(ASNS),solute carrier family 27 member 5(SLC27A5),glu-cosidase II alpha subunit(GANAB),hexokinase 2(HK2),5-methyltetrahydrofolate-homocys-teine methyltransferase(MTR),and maltase-glucoamylase(MGAM).Microarray validation confirmed the diagnostic potential of these genes,with area under the curve(AUC)values for ROC analysis ranging from 0.536 to 0.759.Among these,ORM1,ASNS,and SLC27A5 showed significant differential ability in differentiating LGDHS patients(P=0.016,P=0.035,and P<0.001,respectively),with corresponding AUC of 0.749,0.743,and 0.759,respectively.A logis-tic regression model incorporating these three genes demonstrated an AUC of 0.939,indicat-ing a high discriminatory power for LGDHS.RT-qPCR further validated the differential ex-pression of ORM1 and SLC27A5 between LGDHS and LP groups(P=0.011 and P=0.034,re-spectively),with ASNS showing a consistent trend in expression(P=0.928).Conclusion This study integrates multi-omics approaches to uncover the molecular mecha-nisms underlying LGDHS in CHB.The identification of biomarkers ORM1,ASNS,and SLC27A5 offers a solid basis for the objective diagnosis of LGDHS,contributing to the stan-dardization and modernization of TCM diagnostic practices.

Effect of the Haoqinqingdan decoction on damp-heat syndrome in rats with influenza viral pneumonia

Objective: To investigate the effect of Chinese medicine prescription-Haoqinqingdan decoction on damp-heat syndrome in rats with influenza viral pneumonia and its influence on the immune function. Methods: A total of 48 Wistar rats were randomly divided into the normal control group, the damp-heat syndrome model group, the Haoqinqingdan decoction group (high, medium and low dose group) and the ribavirin group. The body temperature and weight of rats in each group were recorded after modeling. After treatment for 6 d, the concentration of T lymphocyte subgroup (CD3+ CD4+ , CD3+ CD8+ ) was determined by flow cytometry. The OD value of IFN毭/IL-4 was detected by double-antibody sandwich ELISA method, and its concentration was acquired through conversion. Results: After modeling, the temperature and weight of rats in each modeling group showed the increasing trend ( P<0.01). From the second day of treatment, there was significant difference in the body mass between groups, and the rat weight of the control group was higher than in the modeling group ( P<0.05 or 0.01). With the advances of treatment, only the temperature in the medium and high dose Haoqinqingdan decoction groups declined significantly ( P<0.05). After treatment, the CD4+ /CD8+ ratio of the damp-heat syndrome model group decreased more significantly compared with the control group. Elevated CD3+ CD8+ percentages and declined CD4+ /CD8+ ratios can be observed in the low dose group and ribavirin group ( P<0.05). Moreover, the CD3+ CD4+ percentage of ribavirin group was lower than in the control group ( P<0.05). After treatment, the IFN-毭 and IFN-毭/ IL-4 levels in the peripheral blood of rats in the dampheat syndrome group were obviously higher than in the control group ( P<0.05). Conclusions: Compared with ribavirin, the high dose Haoqinqingdan decoction can improve the ratio of T lymphocyte subgroup and Th1/Th2 cell balance more effectively.

Logistic Regression Analysis of Damp-Heat and Cold Damp Impeding Syndrome of Rheumatoid Arthritis:A Perspective in Chinese Medicine

Objective： To investigate a method for quantitative differential diagnosis of damp-heat and cold-damp impeding syndrome of rheumatoid arthritis （RA） in Chinese medicine （CM）. Methods： Laboratory parameters were collected from 306 patients with RA. The clinical symptoms and laboratory parameters were compared between patients with these two syndromes （158 with RA of damp-heat impeding syndrome, and 148 with RA of cold-damp impeding syndrome）, and a regression equation was established to facilitate discrimination of the two RA syndromes. Results： There were significant differences in disease activity score in 28 joints [DAS28 （4）], erythrocyte sedimentation rate （ESR）, white blood cell count （WBC）, C-reactive protein （CRP）, platelet count （PLT）, albumin （ALB） and globulin （GLB） between the two syndrome of RA （P〈0.05）. Logistic regression analysis showed that the parameters ESR, WBC, CRP, joint pyrexia, joint cold, thirst, sweating, aversion to wind and cold, and cold extremities were statistically useful to discriminate damp-heat from cold-damp impeding syndrome. The regression equation was as follows： P=1/{1＋exp[-（3.0-0.021X1-0.196X2-0.163X3- 1.559X4＋1.504X5-0.927X6-1.039X7＋1.070X8＋1.330X9）]}. The independent variables X1-X9 were ESR, WBC, CRP, hot joint, cold joint, thirst, sweating, aversion to wind and cold, and cold limbs. A P value 〉 0.5 signified cold-damp impeding syndrome, and a P value 〈 0.5 signified damp-heat impeding syndrome. The accuracy was 90.2%. Conclusion： The regression equation may be useful for discriminating damp-heat from cold-damp impeding syndrome of RA.

液氢储箱柔性支撑杆设计与仿真分析

随着液氢在民用领域的逐渐普及,其在机载运输过程中除了需要考虑支撑强度和绝热性能外,运载平台的振动也成为了亟须解决的关键问题。然而,在国内,对于此方面的研究较少。由此,提出了一种由一减振模块和球接触绝热模块组成的柔性支撑结构,该结构在实现支撑和绝热的同时对外部的振动进行隔离。首先,详细介绍了柔性支撑的基本原理和详细结构,给出了容积为50 L液氢储罐样件的主要结构参数和运行参数;其次,基于动力学理论对其进行了减振分析,确定弹簧劲度系数、拉压行程、匹配的阻尼系数、强度等参数的设定方案,得出弹簧和阻尼之间的影响关系;最后,建立了支撑杆的参数化结构,开展了传热性能仿真,得出杆组以及杆件各个部件的温度云图。仿真结果表明:柔性支撑杆能够有效降低外部振动的振幅,对大于5 Hz的外部振动,可使其幅值降低至6%以下。此外,得益于减振模块采用细小线径的弹簧结构,加上球接触效果,极大增加了支撑杆的热阻,使得单杆截面内的漏热量仅为22 W/m2,相比相同长度等截面刚性拉杆的热通量降低了55.1%。
