OBJECTIVE To investigate the effect and mechanism of Jingangteng capsules in the treatment of non-alcoholic fatty liver disease （NAFLD）. METHODS Thirty-two SD rats were randomly divided into normal group and modeling group. The modeling group was fed a high-fat diet to establish a NAFLD model. The successfully modeled rats were then randomly divided into model group， atorvastatin group[positive control， 2 mg/（kg·d）]， and Jingangteng capsules low- and high-dose groups [0.63 and 2.52 mg/（kg·d）]， with 6 rats in each group. The pathological changes of the liver were observed by hematoxylin-eosin staining and oil red O staining. Enzyme-linked immunosorbent assay was performed to determine the serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， alanine transaminase （ALT）， aspartate transaminase （AST）， tumour necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， IL-6， IL-18. 16S rDNA amplicon sequencing and metabolomics techniques were applied to explore the effects of Jingangteng capsules on gut microbiota and metabolisms in NAFLD rats. Based on the E-mail：591146765@qq.com metabolomics results， Western blot analysis was performed to detect proteins related to the nuclear factor kappa-B （NF-κB）/NOD-like receptor family protein 3 （NLRP3） signaling pathway in the livers of NAFLD rats. RESULTS The experimental results showed that Jingangteng capsules could significantly reduce the serum levels of TG， TC， LDL-C， AST， ALT， TNF-α， IL-1β， IL-6， IL-18， while increased the level of HDL-C， and alleviated the hepatic cellular steatosis and inflammatory infiltration in NAFLD rats. They could regulate the gut microbiota disorders in NAFLD rats， significantly increased the relative abundance of Romboutsia and Oscillospira， and significantly decreased the relative abundance of Blautia （P＜0.05）. They also regulated metabolic disorders primarily by affecting secondary bile acid biosynthesis， fatty acid degradation， O-antigen nucleotide sugar biosynthesis， etc. Results of Western blot assay showed that they significantly reduced the phosphorylation levels of NF-κB p65 and NF-κB inhibitor α， and the protein expression levels of NLRP3， caspase-1 and ASC （P＜0.05 or P＜0.01）. CONCLUSIONS Jingangteng capsules could improve inflammation， lipid accumulation and liver injury in NAFLD rats， regulate the disorders of gut microbiota and metabolisms， and inhibit NF-κB/NLRP3 signaling pathway. Their therapeutic effects against NAFLD are mediated through the inhibition of the NF-κB/NLRP3 signaling pathway.

Objective To investigate the mechanism by which Yangmai Tongluo formula improves microcirculation disorders induced by high homocysteine(Hcy)levels via regulation of the acid sphingomyelinase(ASM)and endoplasmic reticulum(ER)stress pathways.Methods Fifty male C57BL/6J mice were divided randomly into a control group,Hcy model group,Yangmai Tongluo formula low-/high dose groups(5.3,10.4 g/kg,respectively),and a folic acid group(0.08 g/kg).Except for the control group,microcirculation disorders were induced in all mice using drinking water containing 1.8 g/L Hcy for 6 weeks.After modeling for 2 weeks,mice were administered the corresponding treatments by gavage for 4 weeks.Serum Hey concentrations and the blood perfusion volume of the lower extremity microvessels were measured.Protein expression levels of zonula occludens ZO-1,ZO-2,intercellular adhesion molecule-1(ICAM-1),vascular cell adhesion molecule-1(VCAM-1),ASM,glucose-regulated protein 78(GRP78),and C/EBP homologous protein(CHOP)in the cardiac microvascular endothelium were analyzed using immunofluorescence.Results Serum Hcy levels were significantly increased in the Hcy model group compared with the control group(P＜0.05).Yangmai Tongluo formula did not significantly reduce Hey levels compared with the Hey model group,but blood perfusion in the lower extremities was significantly increased(P＜0.01)and expression levels of ZO-1 and ZO-2 in the cardiac microvascular endothelium were restored(P＜0.001)in the Yangmai Tongluo formula high dose group.It also inhibited the expression of ICAM-1,VCAM-1,ASM,GRP78,and CHOP(P＜0.05),with comparable effects to folic acid.Conclusions Yangmai Tongluo formula improves Hcy-induced microcirculation disorders and endothelial dysfunction by inhibiting ASM activity and alleviating ER stress,via a mechanism closely related to the regulation of endothelial inflammation and barrier stability.These result provide experimental evidence to support the use of traditional Chinese medicine to treat microvascular diseases.

Objective To analyze the status of 2 649 suspected pertussis patients in Xi'an and the changes in laboratory diagnostic indi-cators.Methods 2 649 patients with suspected pertussis who visited the Second Affiliated Hospital of Xi'an Jiaotong University from June 2023 to May 2025 were collected as the research subjects.Nasopharyngeal swabs were collected from the patients,and pertussis nucleic acid was detected by polymerase chain reaction(PCR)-fluorescence probe method.Laboratory diagnostic indicators were an-alyzed.Results Among the 2 649 samples tested,250 were positive for pertussis nucleic acid,with a positive detection rate of 9.44%.The detection rate in male patients was 9.37%(127/1 356),and in female patients was 9.51%(123/1 293),with difference no was statis-tically significant between the two groups(χ2=0.019,P=0.894).There was a statistically significant difference in the positive detection rate among different age groups(χ2=46.473,P<0.05),with the highest positive detection rate in the 7～19 age group(14.98%).The prevalence of pertussis showed a seasonal characteristic with a peak from April to September.21.2%(53/250)of the positive patients were mixed infections.In the 1～14 age group,the white blood cell count(WBC),lymphocyte percentage(LYMP%),and lymphocyte count(LYMP#)in the pertussis infection group were higher than those in the Mycoplasma pneumoniae(MP)infection group(t=10.179,5.819,8.614)and the Respiratory syncytial virus(RSV)infection group(t=16.570,2.618,7.185),and the differences were statistically significant(all P<0.01),respectively.In the＞14 age group,the LYMP%and LYMP#in the pertussis infection group were higher than those in the MP infection group(t=3.275,2.319)and the RSV infection group(t=2.401,4.617),and the differences were statistically significant(all P<0.05),respectively.Conclusion The pertussis infection status in Xi'an area from 2023 to 2025 shows significant char-acteristics in terms of age,season and laboratory test results.It is necessary to further improve the pertussis surveillance system in this area,optimize the clinical diagnosis and treatment process and strengthen the vaccination work of pertussis vaccine.

Rheumatoid arthritis(RA)is characterized by bidi-rectional bone remodeling imbalance,clinically termed the "high resorption-low formation" paradox,stemming not only from osteoclast hyperactivation but also critically involving pro-found suppression of osteoblast differentiation and function.No-tably,this suppression cannot be fully attributed to osteoclast hyperactivity;synovium-resident immune cells exert a pivotal regulatory influence through distinct mechanisms.This review systematically examines how synovial immune cells orchestrate bone remodeling in RA through both paracrine cytokine networks and direct cell-cell communication with bone lineage cells,thereby perturbing physiological homeostasis and driving patho-logical progression.These mechanistic revelations yield innova-tive perspectives on RA pathogenesis,positioning immune-medi-ated osteoimmune dysregulation as a promising therapeutic fron-tier for targeted intervention.

Post-translational modification of protein is a key mechanism for regulating cancer development and immune re-sponses,and has become an important target for cancer diagnosis and treatment.Among them,lactylation modification provides a new perspective for the precise prevention and control of tumors by affecting metabolism and epigenetics.Lactylation modification precisely regulates the functions of histone and non-histone,affecting tumor cell characteristics,microenvironment acidification,and immune cell functions,becoming a key hub connecting metabolic reprogramming and malignant phenotypes.This article reviews the regulatory roles of lactylation modification in tumor development,immune escape,clinical translation,and explores the potential of targeted inhi-bition of lactylation modification and its related pathways,as well as the inhibition of key enzyme activity.

Objective::To examine the impact of hypertensive disorders of pregnancy (HDP) on offspring metabolomics.Methods::We searched five databases: PubMed, Ovid Embase, MEDLINE, Web of Science, and China National Knowledge Infrastructure, and included studies that reported metabolomics among human offspring born to HDP-complicated pregnancies.Results::Database search yielded 4054 articles, and after full-text screening, ten observational studies met inclusion criteria. Half of the studies had a sample size of less than 100 and were all observational studies in preeclampsia (PE) and gestational hypertension.Neonates were the most focused group in all included studies. Offspring born to HDP-complicated pregnancies exhibited statistically significant variations in blood metabolomics compared to their counterparts, characterized by amino acids, lipids, carnitine, and others (e.g., 1α,25-(OH) 2-D). Most studies reported a significant increase in differential metabolites of offspring born to HDP-complicated pregnancies. Four studies ( n = 1109) measured lipids-related metabolites, and all consistently showed that offspring born to PE-complicated pregnancies had significantly higher concentrations than non-PE exposed offspring. Conclusion::The existing evidence suggests an intergenerational effect of HDP on offspring metabolomics. Long-term follow-up studies are needed to advance the health effects of related adverse health outcomes and inform the prevention of offspring’s health.

Malnutrition is one of the main complications for gastric cancer patients, with an incidence rate as high as 65% to 85%, severely affecting their quality of life and survival rate. This issue is particularly prominent during out-of-hospital treatment, as patients often lack nutritional knowledge and do not receive continuous nutritional management. Therefore, ensuring that patients continue to receive effective nutritional management after discharge is crucial. This study explored three primary models of nutritional management for gastric cancer patients after discharge: the multidisciplinary team collaboration model, three-level nutritional management model, and the Internet+ model. It also analyzed the shortcomings and challenges these models face in practice, with the aim of providing a reference for clinical work.

Objective To evaluate the value of molecular markers of thrombine-antithrombin complex(TAT),soluble thrombomodulin(sTM),tissue-plasminogen activator-inhibitor complex(t-PAIC)in the early diagnosis of disseminated intravascular coagulation(DIC)in sepsis patients.Methods Thirty patients diagnosed with DIC secondary to hemoinfect-induced sepsis were selected as the DIC group in the intensive care unit(ICU)of the First Hospital of Lanzhou University from July to September 2023.Thirty patients with sepsis caused by bloodstream infection without DIC were randomly selected as the sepsis group.General data and procalcitonin(PCT),platelet count(PLT),white blood cell count(WBC),the levels of traditional clotting indexes activated partial thromboplastin time(APTT),prothrombin time(PT),fibrinogen(Fib),D-dimer and new clotting indexes(TM,TAT,t-PAIC)were collected.The indicators with statistical significance in univariate analysis were included in multivariate Logistic regression analysis to screen the independent risk factors for DIC in sepsis patients.Receiver operator characteristic curve(ROC curve)was drawn to analyze the diagnostic value of TM,TAT,t-PAIC and their combination in the occurrence of DIC in sepsis patients.Results A total of 60 patients with sepsis were included.There was no significant difference in gender,age,PCT,PLT and WBC between the DIC group and the sepsis group.In terms of traditional coagulation indexes,the PT level in sepsis DIC group was significantly lower than that in sepsis group,and the Fib level was significantly higher than that in sepsis group(both P<0.05).There were no statistically significant differences in APTT and D-dimer levels between the two groups.In terms of new coagulation indexes,TAT,sTM and t-PAIC levels in sepsis DIC group were significantly higher than those in sepsis group(all P<0.05).Multivariate Logistic regression analysis showed that TAT,sTM were independent risk factors for DIC in sepsis patients(both P<0.05).ROC curve analysis showed that TAT,sTM,t-PAIC combined detection had certain value in diagnosis of DIC in sepsis patients,area under the curve(AUC)was 0.735;when the cut-off value was 0.73,the sensitivity was 100.0%and specificity was 43.3%.Conclusion TAT,sTM and t-PAIC could help to predict DIC in sepsis.

Bovine rotavirus(BRV)is an important pathogen causing diarrhea in calves.To understand the genomic charac-teristics and genetic variations in bovine rotavirus,and to further enrich data on the biological characteristics of rotavirus,we aimed to amplify 11 gene segments of the isolated and cultured G6P[1]bovine rotavirus BLL strain,perform whole genome se-quencing,and analyze the molecular characteristics.MEGA7.0 and DNAMAN software were used for homology and typing a-nalysis,and the whole genome phylogenetic tree was constructed to analyze genetic evolution relationships.The complete geno-type of the BLL strain was G6-P[1]-I2-R2-C2-M2-A3-N2-T6-E2-H3.Phylogenetic analysis of the VP7 and VP4 genes of the BLL strain showed that the VP7 gene had the highest homology with RVA/Cow-wt/HB01/China/2021,and the VP4 gene of the BLL strain was in the same branch as RVA/Human-tc/ISR/Ro8059/1995.From the sequence alignment of VP8*amino acids,the sialic acid domain of the BLL strain was found to be similar to that in other P[1]strains,but different from those in other types of strains,except for residue 189,which was the same as that in Ro8059 but different from that in other strains.The results suggested that the BLL strain might potentially infect humans.Therefore,continued monitoring and study of the biological characteristics of this strain are necessary to provide more information and evidence supporting further research on the cross-species transmission of group A rotavirus in China.
