Objective:To investigate the effect of dandelion polysaccharide(DP)on inflammatory response and the protein expression of S100 calcium binding protein A8/A9(S100A8/A9)in lung tissue and small intestinal tissue of rats with multiple organ dysfunction syndrome(MODS).Methods:The two-hit method of hemorrhagic shock and intraperitoneally injected lipopolysaccharide was used to establish a rat model of MODS,and the rats were divided into sham-operation group,model group,low-dose DP group,and high-dose DP group.The organ coefficient and wet/dry weight ratio of the lung and the small intestine were observed for each group of rats;HE staining was used to observe the pathomorphological changes of lung tissue and small intestinal tissue;immunohistochemical staining was used to measure the expression of interleukin-1β(IL-1β),interleukin-6(IL-6),and interleukin-10(IL-10)in lung tissue and small intestinal tissue;Western blot was used to measure the protein expression level of S100A8/A9 in lung tissue and small intestinal tissue.Results:Compared with the sham-operation group,the model group had significant increases in the organ coefficient of the lung(5.849±0.824),the wet/dry weight ratio of the lung(6.556±0.631),the wet/dry weight ratio of the small intestine(6.356±0.535),and the wet weight/length ratio of the small intestine(73.950±5.569).HE staining showed that that the model group had massive in-flammatory cell infiltration in alveolar space and pulmonary interstitium,thickened alveolar wall,and disintegration and fragmentation of the villi of the small intestine,with inflammatory cell infiltration and proliferation of segmental aggregated lymphoid follicles.In the model group,S100A8/A9 was mainly expressed in neutrophils and macrophages,and there were increases in the expression of S100A8/A9,IL-1β,and IL-6 and a reduction in the expression of IL-10 in the lung tissue and small intestinal tissue of rats.After treatment with high-dose DP,there were reductions in the organ coefficient of the lung(4.297±0.462),the wet/dry weight ratio of the lung(5.313±0.495),the wet/dry weight ratio of the small intestine(5.398±0.388),and the wet weight/length ratio of the small intestine(59.417±2.891).The high-dose group also had alleviation of pathological injury in the small intestine,with reductions in the expres-sion of S100A8/A9,IL-1β,and IL-6 and an increase in the expression of IL-10 in lung tissue and small intestinal tissue.Conclusion:DP may alleviate inflammatory response in lung and small intestinal injuries of rats with MODS by inhibiting the expression of S100A8/A9.

ObjectiveTo explore the longitudinal measurement invariance of standardized Constitution in Chinese Medicine Questionnaire （CCMQ） among Chinese adult populations， and to provide evidence for the longitudinal effect analysis of this questionnaire. MethodsA total of 509 adults who voluntarily received 26 weeks of comprehensive traditional Chinese medicine （TCM） constitution fitness intervention were included （3 time points： before intervention， 13 weeks intervention， and 26 weeks intervention）， evaluated by CCMQ with 9 subscales. A single-group confirmatory factor analysis was performed to establish a single-group baseline model with a well-fitting model， and then nested models， that is multiple groups of confirmatory factors analysis， are used to analyze the longitudinal measurement invariance， followed by configural invariance， metric invariance， scalar invariance， and strict invariance. Comparative Fit Index （CFI）， Root Mean Square Error of Approximation （RMSEA）， and Standardized Root Mean Square Residual （SRMR） were used as model fit indicators for the analysis. ResultsThe single-group confirmatory factors analysis proved that the 9 subscales of CCMQ fit well at the three time points （CFI： 0.933~0.992， RMSEA： 0.027~0.080， SRMR： 0.022~0.045）. The multiple-group confirmatory factors analysis showed that the configural， metric， scalar， and strict invariance across time of qi-stagnation and special diathesis constitution were established （ΔCFI＜0.01， ΔRMSEA＜0.01）； the configural， metric， scalar， and partial strict invariance across time of phlegm-dampness constitution subscale were established （ΔCFI＜0.01， ΔRMSEA＜0.01）； the configural， metric， partial scalar and partial strict invariance of 6 subscales， including gentleness， qi-deficiency， yang-deficiency， yin-deficiency， dampness-heat， and blood-stasis constitutions， were all established （ΔCFI＜0.01， ΔRMSEA＜0.01）. ConclusionThe CCMQ met at least metric invariance at 3 time points， which can be applied to the study of whether different time points have the same unit or meaning. The measurement invariance of the 3 subscales of phlegm-dampness， qi-stagnation and special diathesis， special diathesis have longitudinal measurement invariance， so the mean comparison over time could be made； while the 6 subscales of gentleness， qi-deficiency， yang-deficiency， yin-deficiency， dampness-heat， and blood-stasis constitutions meet partial scalar and partial strict invariance， which could be explained partially for the difference in the comparison of the mean over time.
