Objective To evaluate the effect of Shenfu Decoction pretreatment on the function of intestinal mucosal barrier of endotoxemic rats.Methods Twenty-four adult male Sprague-Dawley rats,aged 4-6 months,weighing 180-220 g,were randomly divided into 3 groups (n =8 each):blank control group (group C),endotoxemia group (group E) and Shenfu Decoction pretreatment group (group S).Endotoxemia was induced by lipopolysaccharide 10 mg/kg injected intravenously in anesthetized rats in groups E and S.Normal saline and Shenfu Decoction 5 ml/kg were injected intraperitoneally at 30 min before the model of endotoxemia was established in groups E and S,respectively.At 2 h after the model of endotoxemia was estabhshed,blood samples were obtained from the abdominal aorta for measurement of the plasma concentrations of tumor necrosis factor-α (TNF-α),interleukin6 (IL-6),intestinal fatty acid binding protein (i-FABP) and diamine oxidase (DAO) by ELISA.The distal ileum was harvested for detection of the expression of tight junctional protein Zonula Occludens-1 (ZO-1) in the intestinal mucosa of epithelial cells by immunohistochemistry.The changes in pathological morphology of the intestinal mucosa were examined after one segment of the distal ileum was stained with haematoxylin and eosin.The pathological changes were assessed and graded according to Chiu's score.Results Compared withgroup C,the plasma TNF-α,IL-6,i-FABP and D-lac concentrations were significantly increased,Chiu's scores were increased,and the expression of ZO-1 was down-regulated in groups E and S (P ＜ 0.05).Compared with group E,the plasma TNF-α and IL-6 concentrations were significantly decreased,the plasma i-FABP and D-lac concentrations were decreased,Chiu's scores were decreased,and the expression of ZO-1 was up-regulated in group S (P ＜ 0.05).Conclusion Shenfu Decoction pretreatment can attenuate the damage to the intestinal mucosa and protect the function of intestinal mucosal barrier in endotoxemic rats and inhibition of systemic inflammatory responses is involved in the mechanism.

OBJECTIVE To investigate the clinical value of human leukocyte antigen DR(HLA-DR) expression on monocytes in prediction of prognosis in patients with hospital acquired pneumonia(HAP).METHODS A total of 68 patients suffered from HAP and transferred to intensive care unit(ICU) were enrolled in the study and divided into survivors group and nonsurvivors group according to prognosis.HLA-DR expression on monocytes,acute physiology,age and chronic health evaluation((APACHE)) Ⅱ score,serum cortisol level,T lymphocytes(subpopulation) and natural killer(NK) cell were observed.Relationship between HLA-DR expression on(monocytes) and APACHE Ⅱ score and 28-day mortality rates was analyzed through Logistic regression model.(RESULTS) HLA-DR expression on monocytes in nonsurvivors was significantly lower than that in survivors (P

Background::Thoracic aortic aneurysm (TAA) is a fatal cardiovascular disease, the pathogenesis of which has not yet been clarified. This study aimed to identify and validate the diagnostic markers of TAA to provide a strong theoretical basis for developing new methods to prevent and treat this disease.Methods::Gene expression profiles of the GSE9106, GSE26155, and GSE155468 datasets were acquired from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were identified using the "limma" package in R. Least absolute shrinkage and selection operator (LASSO), support vector machine-recursive feature elimination (SVM-RFE), random forest, and binary logistic regression analyses were used to screen the diagnostic marker genes. Single-sample gene set enrichment analysis (ssGSEA) was used to estimate immune cell infiltration in TAA.Results::A total of 16 DEGs were identified. The enrichment and functional correlation analyses showed that DEGs were mainly associated with inflammatory response pathways and collagen-related diseases. Collagen type I alpha 1 chain ( COL1A1) and synaptotagmin like 2 ( SYTL2) were identified as diagnostic marker genes with a high diagnostic value for TAA. The expression of COL1A1 and SYTL2 was considerably higher in TAA vascular wall tissues than in the corresponding normal tissues, and there were significant differences in the infiltration of immune cells between TAA and normal vascular wall tissues. Additionally, COL1A1 and SYTL2 expression were associated with the infiltration of immune cells in the vascular wall tissue. Single-cell analysis showed that COL1A1 in TAA was mainly derived from fibroblasts and SYTL2 mainly from cluster of differentiation (CD)8 + T cells. In addition, single-cell analysis indicated that fibroblasts and CD8 + T cells in TAA were significantly higher than those in normal arterial wall tissue. Conclusions::COL1A1 and SYTL2 may serve as diagnostic marker genes for TAA. The upregulation of SYTL2 and COL1A1 may be involved in the inflammatory infiltration of the vessel wall and poor extracellular matrix remodeling, promoting the progression of TAA.

Objective To investigate the clinical features and risk factors of primary biliary cholangitis(PBC)comorbid with metabolic associated fatty liver disease(MAFLD)and the interaction between the two diseases.Methods A total of 187 patients who were diagnosed with PBC,MAFLD,or PBC with MAFLD in The First Affiliated Hospital of Kunming Medical University from January 2019 to December 2022 were enrolled and divided into PBC group with 70 patients,PBC+MAFLD group with 38 patients,and MAFLD group with 79 patients.Related data were collected,including general information,clinical symptoms,serological parameters,transient elastography(FibroScan),and non-invasive fibrosis markers,which were compared between the three groups.A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between groups,the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups,and the binary Logistic regression analysis was used for multivariate analysis.Results There were significant differences between the three groups in sex,age,height,weight,body mass index(BMI),and history of autoimmune diseases(P<0.05).In the PBC+MAFLD group,female patients accounted for 89.5%,with a mean age of 57.26±12.72 years and a BMI of 23.35±3.70 kg/m2,and in the PBC group,the detection rate of autoimmune diseases was 25.7%(18 patients).There were significant differences between the three groups in the incidence rates of weakness,poor appetite,pruritus,jaundice,varices,ascites,and splenomegaly(all P<0.05).The PBC+MAFLD group had the common symptoms of weakness in 18 patients(47.4%),poor appetite in 15 patients(39.5%),abdominal pain in 14 patients(36.8%),and abdominal distension in 16 patients(42.1%);the MAFLD group had the common symptoms of abdominal pain in 34 patients(43%)and abdominal distension in 32 patients(40.5%);the PBC group had the common symptoms of weakness in 37 patients(52.9%),poor appetite in 25 patients(35.7%),jaundice in 25 patients(35.7%),abdominal pain in 18 patients(25.7%),abdominal distension in 25 patients(35.7%),varices in 19 patients(27.9%),ascites in 23 patients(32.9%),and splenomegaly in 44 patients(62.9%).The PBC+MAFLD group had a controlled attenuation parameter(CAP),which was higher than that of the PBC group,and the PBC group had significantly higher levels of liver stiffness measurement,aspartate aminotransferase-to-platelet ratio index(APRI),and fibrosis-4(FIB-4)than the MAFLD group(all P<0.05).The factors without multicollinearity were included in the regression analysis,and with the PBC group as the reference group,FIB-4(odds ratio[OR]=0.218,95%confidence interval[CI]:0.069-0.633,P<0.05)and history of autoimmune diseases(OR=0.229,95%CI:0.067-0.810,P<0.05)were influencing factors for the onset of PBC with MAFLD;with the MAFLD group as the reference group,ALT(OR=0.157,95%CI:0.025-1.000,P<0.05)and TBil(OR=0.995,95%CI:0.990-0.999,P<0.05)were influencing factors for the onset of PBC with MAFLD.Conclusion PBC with MAFLD lacks specific clinical manifestations,and PBC patients tend to have more severe clinical manifestations and a higher incidence rate of liver function decompensation.PBC comorbid with MAFLD may not aggravate the disease progression of PBC.

Objective Each item of the Chronic Hepatitis Quality of Life Scale (V2.0) was thoroughly analyzed and evaluated according to classical test theory (CTT) and item response theory (IRT). Methods The QLICD-CH (V2.0) scale was used to assess the life quality of 226 patients with chronic hepatitis who were hospitalized in the Department of Infectious Diseases from March 2019 to January 2020. By using CTT's coefficient of variation method, factor analysis method, Cronbach's alpha coefficient method and correlation coefficient method, macroscopic statistical analysis on the scale results was performed. IRT was used to microscopically analyze the information content, discrimination coefficient and difficulty parameters of each item. Results CTT analysis revealed that 36 items of the QLICD-CH (V2.0) scale satisfied three of the four statistical methods. IRT analysis showed that the average information content of 36 items was greater than 0.108, with the degree of discrimination ranging from -0.387 to 3.574; the degree of discrimination of 40 items was greater than 0.30; the difficulty coefficient of each item ranged from -14.805 to 9.057, with 31 items conformed to [-4, 4] and a monotonically increasing trend from b1 to b4. Conclusion The majority of items on the QLICD-CH (V2.0) scale perform well, but there are a few items that could be improved, optimized, or removed.
