Serum metabolic profiles of all subjects were analyzed using ultra-performance liquid chromatography coupled with quadruple-time-of-flight mass spectrometry. The metabolic characteristics of the ST/KDP subjects were determined, and the corresponding biomarkers were predicted. The metabolomics data from the healthy → ST/KDP subjects were collected for further verification.RESULTS: Twelve metabolites in the ST/KDP subjects were different from those of the healthy control subjects. Of these metabolites, according to the prediction, except for octanoic acid, other metabolites might characterize ST/KDP. Ten metabolites at the outcome ST/KDP stage were different from those at the initial(control) stage. Through the comparison of these metabolites with the predicted metabolites, five common metabolites, including upregulated glutamate, serotonin, oroticacid and 8-oxoguanine, as well as downregulated taurine, were found. These common metabolites were significantly associated with canonical pathways including calcium signaling, γ-aminobutyric acid(GABA) receptor signaling, purine and pyrimidine biosynthesis, taurine biosynthesis, and serotonin receptor signaling.CONCLUSION: The metabolic pathogenesis in ST/KDP subjects was characterized by upregulated glutamate, serotonin, orotic acid and 8-oxoguanine, as well as downregulated taurine, additionally, perturbations of calcium signaling, GABA receptor signaling, purine and pyrimidine biosynthesis, taurine biosynthesis, and serotonin receptor signaling.展开更多

After the isolation of peripheral white blood cells(PWBCs), total RNA was extracted, and quality control was performed on all RNA samples. Microarray experiments were conducted using the Agilent human whole genome gene chip, and genes demonstrating differential expression were screened. Bioinformatics analysis was conducted on these genes using several online databases.RESULTS: We screened a total of 175 differentially expressed genes(DEGs), of which 111(63%) were down-regulated and 64(37%) were up-regulated in T2DM-SDP patients compared with healthy controls. Among the 175 genes, 158 had biological function annotations: 46(29%) were directly related to an individual's immune regulation or response, 25(16%) were associated with substance and energy metabolism of PWBCs which could also indirectly influence immunity, and the remaining87(55%) were involved in a variety of PWBC biological processes that might eventually influence the immune function. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that the DEGs were predominantly enriched in seven immune-related pathways. Hierarchical cluster analysis identified gene expression patterns that were distinguishable between the two study groups.CONCLUSION: Our results suggest that T2DM-SDP patients experience significant hypoimmunity and/or immune dysfunctions, and possess a specific gene expression profile. These findings offer new insights into SDP and the clinical pattern differentiation of T2DM-SDP.展开更多

文摘OBJECTIVE:The study aim was to use existing relevant indexes to establish an index series for the quantitative measurement of Qi deficiency pattern(QDP) in Traditional Chinese Medicine(TCM).METHODS:Seventeen indexes of arterial oxygen saturation(SaO_2),TCM pulse diagnosis,heart rate,and blood pressure were integrated into an index series,and 94 selected subjects were divided into a healthy control group,a mild QDP group,and a typical QDP group.All three groups were then synchronously given a breath-holding(BH) test and index detections using TCM apparatus for auxiliary diagnosis and treatment and a photoplethysmograph.The detections were carried out repeatedly until there was no monotonic change in the value of the minimal SaO_(2d)uring a BH measurement(SaO_(2 min)) or in the duration of BH during a BH measurement(TBH).RESULTS:BH measurement and index detection data from 380 eligible cases were analyzed and a significant intergroup difference was found for 12 indexes.CONCLUSION:An index series for quantitative QDP measurement could comprise the 12 effective indexes:RSaO_(2d)(rate of decline of SaO_(2d)uring a BH measurement),RSaO_(2r)(recovery rate of SaO_2 after a BH measurement),SaO_(2 min),BFV(blood flow velocity),TSaO_(2d)(the time at which SaO_2 started declining during a BH measurement),TBH,TSa_(O2 min)(the time of occurrence of the minimal SaO_(2d)uring a BH measurement),TSa O_(2 max)(the time of occurrence of the maximal SaO_2 after a BH measurement),PTP(pulse-touching pressure),SBP(systolic blood pressure),PWV(pulse wave velocity),and DBP(diastolic blood pressure).Of the indexes,RSaO_(2d)could play akey role in quantitative QDP measurement;RSaO_(2r) and Sa O_2 mincould be used to differentiate the QDP symptom of shortness of breath and as early-warning indexes for chronic obstructive pulmonary disease.BFV,TSaO_(2d),and TBHcould be used to quantitatively assess the QDP symptoms of spontaneous perspiration and shortness of breath.
文摘目的:探讨降红方对高原地区慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)稳定期气虚血瘀证患者血气指标、肺功能、改良英国医学研究委员会呼吸问卷(modified medical research council dyspnea scale,mMRC)评分、COPD评估测试表(COPD assessment test,CAT)中医证候积分和临床疗效的影响。方法:选取60例长期生活在高原地区,被诊断为COPD稳定期并辨证为气虚血瘀证的患者,随机分为治疗组和对照组,每组30例。两组患者均给予布地格福吸入气雾剂常规西医治疗,治疗组同时口服降红方治疗,两组均治疗8周。比较两组患者治疗前后血气指标、肺功能、mMRC评分、CAT评分、中医证候积分、临床疗效和不良反应发生情况。结果:治疗后治疗组患者PaO_(2)、SPO_(2)、氧合指数较对照组上升(P<0.05),PaCO_(2)较对照组下降(P<0.05);治疗组患者肺功能FEV1%Pred水平高于对照组(P<0.05);治疗组患者mMRC分级分布改善更明显(P<0.05);治疗组患者CAT评分下降幅度大于对照组(P<0.05)。治疗组患者各项中医证候积分减少及总积分减少优于对照组(P<0.01);治疗组临床总有效率[93.3%(28/30)]高于对照组[73.3%(22/30)](P<0.05)。结论:降红方能改善高原地区COPD稳定期气虚血瘀证患者血气指标,提高肺通气功能,提高患者生活质量,有效改善临床中医证候和临床疗效。
