ObjectiveThis paper aims to investigate the material basis of the anti-inflammatory efficacy and mechanism of action of Bushen Tongdu prescription （BSTDP）. MethodsThe chemical components of BSTDP and its blood-absorbed components in vivo were systematically identified by using ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-LIT-Orbitrap-MS）. Network pharmacology was employed to screen blood-absorbed bioactive components and potential targets of this formula. A protein-protein interaction （PPI） network of core targets was constructed to conduct enrichment analysis. Molecular docking was further utilized to verify the binding affinity between key components and targets. The inflammatory model was established and verified in vivo by using a transgenic zebrafish Tg （mpx： GFP）. At three days post-fertilization （3 dpf）， larvae of zebrafish were randomly assigned to blank group， model group， positive drug dexamethasone acetate group （75 μmol·L^-1）， and BSTDP groups with low， medium， and high doses （500， 1 000， and 2 000 mg·L^-1）. The distribution and quantity of neutrophils in the yolk sac region were observed under a fluorescence microscope. The mRNA expression levels of key genes in the toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor kappa-B （NF-κB） signaling pathway and inflammatory factors including interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） were detected by Real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsA total of 120 chemical components were identified in BSTDP， among which 26 original components were confirmed by using serum pharmacochemical methods. A total of 227 common targets linking rheumatoid arthritis （RA） and the blood-absorbed components were screened by network pharmacology. It is suggested that pseudobrucine， vomicine， sinapine， rehmannioside， cinnamyl alcohol glycoside， and methylephedrine exert anti-inflammatory effects by acting on core targets including protein kinase B1 （Akt1）， signal transducer and activator of transcription 3 （STAT3）， tumor necrosis factor （TNF）， TLR4， mitogen-activated protein kinase 14 （MAPK14）， and phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit α （PIK3CA）， thereby modulating multiple signaling pathways such as TLR4 and NF-κB. In vivo verification in zebrafish demonstrates that the maximum tolerable concentration of Bushen Tongdu Formula is 2 000 mg·L^-1. Compared to those in the blank group， zebrafish in the model group showed a significantly higher number of neutrophils in the yolk sac region （P<0.01） and rising mRNA levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β （P<0.01）. Compared to that in the model group， the number of neutrophils was significantly reduced in BSTDP groups with medium and high doses， as well as the dexamethasone acetate group （P<0.05， P<0.01）. There was no statistically significant difference in the low dose group. The mRNA expression levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β were significantly down-regulated （P<0.05， P<0.01）. ConclusionThis paper identifies the material basis of the efficacy of BSTDP， demonstrating that the formula can exert an anti-inflammatory effect through the TLR4/MyD88/NF-κB signaling pathway. The results provide scientific experimental evidence for its further clinical application.

Objective To explore the potential clinical value of the ratio of glycated albumin to albumin(GA/ALB)in the occurrence of heart failure(HF)among patients with coronary atherosclerotic heart disease(CHD).Methods A total of 337 CHD patients admitted to the Department of Cardiology in Shanxi Provincial People's Hospital from July 2023 to June 2024 were selected in this study.CHD patients were divided into HF group and non-HF group based on whether they progressed to HF.The clinical data and laboratory parame-ters of the two groups were compared.Restricted cubic spline curve was used to analyze the relationship be-tween GA/ALB levels and the risk of HF in CHD patients.Receiver operating characteristic curve was applied to evaluate the diagnostic efficacy of GA/ALB,GA,platelet to lymphocyte ratio(PLR),and monocyte to lym-phocyte ratio(MLR)in CHD patients with the occurrence of HF.Logistic regression was used to explore the relationship between serum GA/ALB levels and the risk of CHD patients occurrence of HF,and to analyze the degree of influence and stability of subgroup variables on results.Results There were statistically significant differences in GA/ALB,GA,PLR,MLR,and other indicators between the HF group and the non-HF group in CHD patients(P＜0.05).A non-linear relationship was observed between GA/ALB levels and the risk of HF in CHD patients.When the value of GA/ALB multiplied by 10 was less than 5.751,the risk of HF in CHD pa-tients increased with the increase of GA/ALB levels(P＜0.001).GA/ALB was an effective predictor for HF occurrence in CHD patients.Multivariable Logistic regression model showed that GA/ALB was an independ-ent risk factor for CHD patients with occurrence of HF.Subgroup analysis also confirmed the stability of GA/ALB in predicting the occurrence of HF in CHD patients.Conclusion GA/ALB is an independent risk factor for the occurrence of HF in CHD patients,and monitoring GA/ALB levels provides predictive value for the oc-currence of HF in these patients.

Objective To investigate the clinicopathological features,immunophenotype,diagnosis and treatment of SMARCA4(BRG1)-deficient carcinoma.Methods Clinical data of 11 patients with SMAR-CA4(BRG1)-deficient cancer were collected.The morphologic and immunohistochemical features of this tumour were summarized,and the relevant literature was reviewed.Results Among the 11 cases of SMARCA4(BRG1)-deficient carcinoma,eight were male and three were female,with median age of 60.Seven patients underwent radical resection,and four underwent traditional joint targeted chemotherapy and immunotherapy.Microscopically,the tumor cells were epithelioid,rhabdoid or spindle-shaped,with prominent eosinophilic nucleoli and frequent mitoses(>5/10 HPF).Multiple foci of necrosis were found in the tumor tissue,a large number of tumor emboli in the blood vessels and myxoid stromal degeneration.Among these cases,11 cases showed loss of SMARCA4(BRG1)expression,whereas the CK and Vim markers were expressed,SMARCB1(INI1)expression was retained,and p53 mutation was detected.The tumor cells showed high proliferation activity(Ki-67>60%),and synaptophsin was moderately positive.Three cases were mismatch repair deficient and respectively showed the loss of MLH1/PMS2,PMS2 and MSH6 expression.Conclusion The incidence of SMARCA4(BRG1)-dificient carcinoma is low.It can be easily confused with other tumors and is difficult to be diagnosed before operation,which requires confirmation by immunohistochemistry.

Objective:This study analyzes the expression level of miR-1180-3p and constructs the regulatory network of relevant ceRNA by integrating the DNA methylation and gene expression profile of hepatocellular carcinoma from the Cancer Genome Atlas (TCGA).Methods:Firstly, the expression level of miR-1180-3p in hepatocellular carcinoma and adjacent tissues was analyzed by TCGA database, and the differential expression of lncrna and mRNA was screened. Secondly, the LncBase database and the TargetScan database were used to predict the relationship between miR-1180-3p and lncRNA and mRNA, and the DNA methylation-mediated lncRNA was screened by the DNA methylation profile of lncRNA. Finally, Cytoscape software was used to construct miR-1180-3p relevant ceRNA network, and WebGestalt website was used to perform GO and KEGG analysis of related mRNA in ceRNA.Results:Compared with patients with low expression of miR-1180-3p (mean overall survival duration, 5.69 ± 0.35 years), patients with high expression of miR-1180-3p had shorter overall survival time (mean overall survival duration, 3.99 ± 0.47 years), indicating that the high expression of miR-1180-3p was hepatocellular carcinoma risk factor affecting the prognosis ( HR = 1.28, 95% CI = 1.1 ~ 1.5, P < 0.01). A miR-1180-3p related ceRNA regulatory network was constructed in this study, which contained 2 lncRNAs (F11-AS1 and LINC01511) and 37 mRNAs. Conclusion:This study has successfully constructed miR-1180-3p relevant ceRNA regulatory network, and DNA methylation-mediated F11-AS1 and F11-AS1/miR-1180-3p/C11of54 ceRNA regulatory axis has played an important role in the occurrence and development of hepatocellular carcinoma.

Objective: To analyze vaccination situation of oral live attenuated rotavirus vaccine (LLR strain) among children from six provinces in China. Methods: In 2014, we selected 12 counties in Guangdong, Jiangsu, Chongqing, Jiangxi, Heilongjiang and Gansu provinces by using stratified cluster random sampling method and extract information of children born from January 1, 2008 to December 31, 2012 from Children's Immunization Information System. We investigated ten children of each birth cohort in each county by checking the vaccination certification, and a total of 606 children were investigated. A survey was conducted to check the information of the children's vaccination certification with the data of Children's Immunization Information System by questionnaire including the basic information (province, county, name, gender, birth date, etc) and the rotavirus vaccination (vaccination date, dose, etc) to analyze the rotavirus vaccination situation. Results: 340 of 606 children were male. There were 121, 124, 122, 119 and 120 children born in 2008-2012, respectively. The proportions of the first and the second dose of rotavirus vaccination were 32.8% (199) and 9.7% (59). The proportion of the third dose of rotavirus vaccination among children born between 2008 and 2010 was 3.5% (13) since children born in 2011 and 2012 did not reach the age of third dose vaccination. The proportion of the first dose of rotavirus vaccination in high, middle and low per capita disposable income areas was 45.0% (91), 37.7% (77) and 15.5% (31) respectively (χ²= 43.15, P<0.001). Among 199 children vaccinated with the first dose of vaccine, the vaccination age mainly concentrated in 2 to 21 months, of which the peak was 5 to 13 months (66.8%, 133). The intervals between 2 doses of vaccination were mainly from 12 to 13 months (42.4%, 25) among the 59 children who received at least 2 doses of vaccine. In the 13 children vaccinated with 3 doses, the intervals between the second and the third dose were 12 months (5). Of the 271 doses of rotavirus vaccine vaccinated during 2008-2014, 34.7% (94 doses) were vaccinated in June-August, 88 were vaccinated simultaneously with 18 other vaccines, accounting for 32.5% of the total. Of the 18 other vaccines, inactivated vaccines such as diphtheria vaccine (30 doses), Hib vaccine (14 doses), group A meningitis vaccine (10 doses) were predominant. Conclusion The proportion of rotavirus vaccination was low and the vaccination age was relatively late. The vaccination mode was different from the recommendation of WHO. It is recommended that routine immunization of rotavirus vaccines should be carried out in early-months of children.
