OBJECTIVE To observe the clinical efficacy of mycophenolate mofetil （MMF） combined with Budesonide enteric capsules in the treatment of high-risk progressive immunoglobulin A nephropathy （IgAN）. METHODS A total of 150 adult patients with high-risk progressive IgAN who attended the Department of Nephrology， Chongqing University Three Gorges Hospital， between August 1， 2024 and March 1， 2025 were enrolled in this study. The control group （ n ＝94） received MMF combined with glucocorticoid， while the observation group （ n ＝56） received MMF combined with Budesonide enteric capsules. The 24-hour urine protein （24 h UP）， estimated glomerular filtration rate （eGFR）， and albumin （ALB） levels of patients in both groups were compared at 1， 2， 3， and 6 months post-treatment. The complete response （CR） rate and overall response rate were calculated for both groups at 1， 2， 3， and 6 months post-treatment. Adverse reactions occurring during treatment were compared between the two groups. RESULTS Compared with before treatment， 24 h UP decreased significantly in both groups at different time points after treatment （ P ＜0.05）， and ALB increased significantly （ P ＜0.05）. However， there was no significant change in eGFR （ P ＞0.05）. The 24 h UP in the observation group at 1， 2， and 3 months after treatment was significantly lower than that of the control group （ P ＜0.05）， while the ALB level was significan tly higher （ P ＜0.05）. However， at 6 months after treatment， there was no statistically significant difference in these two indicators between the two groups （ P ＞0.05）. There was no statistically significant difference in eGFR between the two groups at different time points after treatment （ P ＞0.05）. The overall response rates in the observation group at 1 and 2 months after treatment were significantly higher than those in the control group （ P ＜0.05）. There was no statistically significant difference in the overall response rate at the remaining treatment time points and the CR rate at all time points between the two groups （ P ＞0.05）. Patients in the observation group had significantly lower rates of skin abnormalities， elevated blood glucose， and overall adverse reactions compared with the control group （ P ＜0.05）. CONCLUSIONS Compared with MMF combined with glucocorticoids， MMF combined with Budesonide enteric capsules for the treatment of high-risk progressive IgAN patients can reduce proteinuria and improve serum ALB levels more quickly， significantly increase the early overall response rate， and significantly reduce glucocorticoid-related skin adverse reactions， blood glucose elevation， and the overall incidence of adverse reactions， demonstrating a better short-term benefits.

ObjectiveTo explore the efficacy and mechanism of Euphorbia humifusa on acute kidney injury （AKI） based on network pharmacology， molecular docking and experimental verification. MethodsThe active components and targets of E. humifusa were retrieved from TCMSP and SwissTargetPrediction database， and the AKI targets were screened by GeneCards and Online Mendelian Inheritance in Man（OMIM） databases. The drug targets and disease targets were intersected to construct a protein-protein interaction network， and the intersection targets were subjected to gene ontology （GO） and Kyoto encyclopedia of genes and genomes （KEGG） enrichment analysis. Discover Studio software was used to verify the molecular docking of key components and core targets. Gentamicin （GM） was used to induce AKI rat model. Control group， model group， verapamil （16 mg·kg^-1） group， E. humifusa extract （18， 54， 162 mg·kg^-1·d^-1） group and E. humifusa 70% ethanol extract （423 mg·kg^-1） group were continuously administered for 14 days. Urine volume was detected 24 h after modeling and administration. Serum creatinine （SCr）， Blood urea nitrogen （BUN）， 24-hour urine protein （24 hUTP） and uric acid （UA） content； the contents of malondialdehyde （MDA）， glutathione （GSH）， superoxide dismutase （SOD）， carbon monoxide synthase （NOS） and lactate dehydrogenase （LDH） in kidney were measured. The levels of interleukin （IL）-6 and tumor necrosis factor （TNF）-α in serum were detected by enzyme linked immunosorbent assay（ELISA） kit. The pathological changes of renal tissue were detected by hematoxylin-eosin （HE） and Masson staining. Western blot was used to detect the expression of PI3K/protein kinase B（Akt）/NF-κB signaling pathway-related proteins. ResultsIn this study， 13 active components such as kaempferol， luteolin， apigenin， gallic acid and quercetin were screened and identified from E. humifusa. Through bioinformatics analysis， these components and AKI have a total of 289 targets， of which 62 are core targets， including Akt1， TNF， tumor protein p53（TP53） and IL-1β. These targets are mainly involved in the regulation of biological processes such as NF-κB signaling pathway， HIF-1 signaling pathway， TNF signaling pathway， PI3K/Akt signaling pathway and mitogen-activated protein kinase（MAPK） signaling pathway. In animal experiments， we successfully constructed a GM-induced AKI model in rats. Compared with the model group， E. humifusa extract could significantly reduce the levels of 24 hUTP， BUN and SCr in rats （P<0.01）， indicating its improvement effect on renal function. In addition， the extract of E. humifusa also significantly reduced LDH activity and MDA content in rat kidney tissue （P<0.05， P<0.01）， and significantly increased SOD， NOS activity and GSH content （P<0.05）， indicating that the extract of E. humifusa has the potential of anti-oxidation and protection of renal function. Further analysis of inflammatory factors showed that the levels of IL-6 and TNF-α in serum of rats treated with E. humifusa extract were significantly decreased （P<0.01）， indicating that E. humifusa extract had anti-inflammatory effects. In addition， the extract of E. humifusa can also regulate the protein expression of PI3K/Akt/NF-κB signaling pathway， which further confirmed its mechanism of reducing GM-induced AKI. ConclusionThe extract of E. humifusa has a significant therapeutic effect on acute kidney injury through its multi-component and multi-target mechanism. Its effect is reflected in improving renal function， anti-oxidation， anti-inflammation and regulating immune response. These findings provide a scientific basis for the application of E. humifusa in the treatment of acute kidney injury， and point out the direction for future drug development and clinical research.

OBJECTIVE To analyze the clinical characteristics and the correlation between laboratory indicators and prognosis of severe Mycoplasma pneumoniae pneumonia(SMPP)in children.METHODS A total of 85 children with SMPP admitted to Anhui Provincial Children's Hospital from Nov.2021 to May 2024 were selected as the study subjects.Based on clinical typing at admission,they were divided into a high-risk group(n=59)and a low-risk group(n=26).The clinical manifestations,laboratory indicators and outcomes at 28 days of treatment were compared between the two groups.RESULTS The duration of fever and cough before admission in the high-risk group was(7.17±1.09)days and(6.79±1.25)days,respectively,which was longer than that in the low-risk group(P＜0.05).There were no statistically significant differences in pulmonary auscultation(wheezing rales,moist rales)and extrapulmonary complications between the two groups.The levels of C-reactive protein(CRP),serum amyloid A(SAA),platelets(PLT),fibrinogen(FIB),D-dimer(DD)and N-terminal pro-brain natriuretic peptide(NT-proBNP)in the high-risk group were(11.62±1.45)mg/L,(226.88±36.83)mg/L,(3 18.57±39.82)×109/L,(4.28±0.74)g/L,(0.81±0.12)μg/ml and(2 295.48±413.75)pg/ml,respectively,all of which were higher than those in the low-risk group(P＜0.05).Within 28 days after treatment of children in both groups,one patient in the high-risk group died.CONCLUSIONS Compared with children with SMPP in the low-risk group,those in the high-risk group have a higher risk of prognostic mor-tality,suggesting a correlation between the children's blood CRP,SAA,PLT,FIB,DD and NT-proBNP levels and the prognosis of children with SMPP.

This study is to explore the antibiofilm activity of tirapazamine(TPZ)against Salmonella and the mechanism of inhibiting biofilm formation.In this study,crystal violet staining was used to determine the effect of TPZ on the minimal biofilm inhibitory concentration(MBIC)of Salmonel-la and on the development stage of Salmonella biofilm.The effects of TPZ on bacteria and biofilm of Salmonella were observed by scanning electron microscope and fluorescence microscope.Phe-nol-sulfuric acid method,spectrophotometer and BCA method were used to detect the effects of the bacteria on the content of main extracellular matrix of Salmonella.The autocoagulation and hydro-phobicity of Salmonella were measured and their effects on the cell wall of Salmonella were meas-ured by AKP method.The result showed that the MBIC value of TPZ on Salmonella ATCC 14028 was 1.563 μmol/L,it had destructive effects on both Salmonella bacteria and mature biofilm structure,it inhibited the formation of early Salmonella biofilm in a concentration-dependent manner,and inhibited the synthesis and secretion of extracellular polymers in Salmonella biofilm.The autoagglutination ability,hydrophobicity and cell wall integrity of Salmonella were affected.To sum up,the TPZ may inhibit the formation of a large number of Salmonella biofilms in the early stage of biofilm development by affecting the extracellular polymer and cell agglutination a-bility,which is expected to be a potential candidate drug against biofilm infection and provide a new idea for finding alternative antibiotics.

Using the convenience sampling method, 18 experts were selected for two rounds of expert correspondence from October to December 2023, and the final evaluation index system was determined based on the correspondence.Results:In the two rounds of expert correspondence, the effective recovery rates of the questionnaires were 100.00% (18/18) and 88.89% (16/18), respectively, the expert authority coefficients were 0.97 and 0.97, and the Kendall's harmony coefficients were 0.15 and 0.24, respectively (all P<0.01). The job competence evaluation index system for VTE control liaison nurses contained six primary indicators, 18 secondary indicators, and 55 tertiary indicators. Conclusions:The job competence evaluation index system for VTE control liaison nurses constructed in this study is set up scientifically and reasonably, and the evaluation content is comprehensive and practical, which can provide reference for the training and assessment of hospital VTE control liaison nurses.

Objective:To explore the current status of orthopedic nurses' health science popularization information generation capacity and training needs in Beijing.Methods:This study was a cross-sectional survey. Convenience sampling was used to select 818 orthopedic nurses from 54 hospitals (48 Class Ⅲ hospitals and 6 ClassⅡ hospitals) in Beijing in April 2024 for the study. General Information Questionnaire, Self-assessment Scale for Orthopedic Nurses' Health Science Popularization Information Generation Capacity, and Training Needs Scale for Orthopedic Nurses' Health Science Popularization Information Generation Capacity were used to survey the study participants. Multiple linear regression was used to analyze the factors influencing orthopedic nurses' health science popularization information generation capacity. A total of 818 questionnaires were distributed and 781 valid questionnaires were recovered, with a valid recovery rate of 95.48% (781/818) .Results:The 781 orthopedic nurses had a total score of [49.00 (42.00, 57.00) ] on the Self-assessment Scale for Orthopedic Nurses' Health Science Popularization Information Generation Capacity. Multiple linear regression analysis showed that years of working experience, health status, intention to participate in health science popularization, stage of health science popularization behavior, and frequency of participation in health science popularization training were the factors influencing orthopedic nurses' health science popularization information generation capacity ( P<0.05), which explained 17.30% of the total variation. Beijing orthopedic nurses had training needs in five areas of assessing audience needs, assessing message risk, revising and improving messages, generating messages, and pretesting messages. Conclusions:The Beijing orthopedic nurses' health science popularization information generation capacity is at a medium and high level, but there is still much room for improvement. It is recommended to pay attention to the physical and mental health of orthopedic nurses, improve the work commitment, and build a long-term incentive mechanism to stimulate the enthusiasm of orthopedic nurses in health science popularization. Medical institutions or specialty societies should actively formulate training programs, build training platforms, and gradually perfect the orthopedic nurses' health science popularization training system in order to comprehensively enhance the health science popularization information generation capacity and help China's great health.

Objective:To evaluate the epidemiological protective effect of a booster dose of acellular DTP vaccine (DTaP) against pertussis in 6-year-old children.Methods:A retrospective cohort study was conducted to compare the incidence of pertussis in 6-year-old children who received DTaP versus DT vaccine boosters in 2023 over a two-year period from May 2023 to May 2025. The protective effect of the fifth dose of DTaP against pertussis in 6-year-old children was evaluated.Results:A total of 960 participants were enrolled in this study, including 480 children in the experimental group who received the fifth dose of DTaP vaccine and 480 children in the control group who received the DT vaccine booster. Baseline characteristics were balanced between the two groups. There were six confirmed cases of pertussis in the experimental group, with a reported incidence rate of 1.25%. In the control group, 14 pertussis cases were reported, with a reported incidence rate of 2.92%. The protective effectiveness(VE) of the DTaP vaccine against pertussis was 57.14% (95% CI:-10.59%-83.39%). For 6-year-old children who completed the booster immunization, the incidence data of pertussis were collected from the 14 th day after vaccination (i.e., the study day 0). Based on the annual cumulative incidence rate, the VE of DTaP against pertussis at 6, 12, 18, and 24 months after vaccination was 100%, 63.80% (95% CI:-14.49%-88.55%), 64.59% (95% CI: 1.17%-87.31%), and 57.60% (95% CI:-10.80%-83.78%), respectively. In the DTaP group, the annual cumulative incidence rate of 12 to 24 months did not show a significant upward or downward trend ( Z=-0.995, P=0.320). Conclusion:Boosting 6-year-old children with the DTaP vaccine provides measurable protection against pertussis. The protective efficacy is significant in the early stage (0 to 6 months) after vaccination, and it still remains effective at 12 to 24 months.

Objective:To investigate the anti-fatigue effect of Dendrobium and Panax Quinquefolius Granules(DPQG)on the overtrained mice,and to clarify its possible mechanism.Methods:A total of 48 mice were randomly divided into control group(equal volume of distilled water),low dose of DPQG group(400 mg·kg-1 DPQG),medium dose of DPQG group(800 mg·kg-1 DPQG),and high dose of DPQG group(1 600 mg·kg-1 DPQG).The DPQG were administered by gavage for 35 d,and the rotarod test and swimming endurance test were performed 30 min after last administration.Serum,liver tissue,and muscle tissue were collected from the mice in various groups.ELISA method was used to detect the serum lacticacid(LAC)levels and lactate dehydrogenase(LDH)activities,and the malondialdehyde(MDA)levels,superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)activities,and the liver glycogen and muscle glycogen levels in muscle tissue of the mice in various groups;HE staining was used to observe the pathomorphology of muscle tissue of the mice.Transcriptomics and metabolomics technologies were used to identify the key genes and metabolites in muscle tissue of the mice in control group and high dose of DPQG group and to analyze the correlations between differentially expressed genes(DEGs)and differentially expressed metabolites.Results:Compared with control group,the rod turning exhaustion time of the mice in different doses of DPQG groups were significantly increased(P＜0.05),and the swimming exhaution time of the mice in high dose of DPQG group was increased(P＜0.05).Compared with control group,the LDH,SOD,and GSH-Px activities of the mice in medium and high doses of DPQG groups were increased(P＜0.01).Compared with control group,the levels of MDA and liver glycogen of the mice in medium and high doses of DPQG groups were decreased(P＜0.05 or P＜0.01).The transcriptomics sequencing results showed that DPQG mainly acted on DEGs such as Trib3 and Olfr495;the Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis results showed that the DEGs were mainly enriched in olfactory-related processes and signaling pathways;the metabolomics KEGG analysis results showed that the differential metabolites were mainly enriched in the regulation pathway of inflammatory mediators on tryptophan(TRP);the combined analysis of transcriptomics and metabolomics results showed that the piezo1 gene had high correlations with the differential metabolites β1-solamarine(r=-1,P＜0.05)and tilidine(r=1,P＜0.05).Conclusion:DPQG can exert an anti-fatigue effect on the overtrained mice by modulating LAC metabolism and glycogen homeostasis,as well as maintaining the oxidative/antioxidant balance in the body;its anti-fatigue mechanism is related to the Olfr495 and piezo1 genes and the regulation pathway of inflammatory mediators on TRP channels.
