Objective: To explore the association between dietary inflammatory index (DII) and elevated blood pressure among primary school students, and to analyze the mediating role of body mass index (BMI) in this association, so as to provide a scientific basis for the early prevention of childhood hypertension and dietary guidance. Methods: Research conducted based on the Ma anshan Child Growth Cohort in Anhui Province. From April to June 2024, 4 057 primary school students were selected as study subjects using a multi stage cluster sampling method. Dietary information was collected via Semi quantitative Food Frequency Questionnaire to calculate the DII score. BMI was obtained by measuring students height and weight. Elevated blood pressure was defined based on the Blood Pressure Reference Standards for Children Aged 3-17 Years. Logistic regression was used to analyze the association between DII scores and the risk of elevated blood pressure, and the Bootstrap method was employed to test for mediating effects. Results: The detection rate of elevated blood pressure among primary school students was 10.1% (408 cases). Multivariate Logistic regression analysis showed that, after adjusting for covariates such as gender and age, for each standard deviation increase in the DII score ( s =1.94), the risk of elevated blood pressure increased by 15% ( OR =1.15, 95% CI =1.04- 1.28 , P <0.05). Compared with the lowest quartile group of DII scores ( Q 1), students in the highest quartile group ( Q 4) had a 1.31-fold higher risk of elevated blood pressure ( OR =1.31, 95% CI =1.00-1.76, P <0.05). Restricted cubic spline results indicated a linear dose response relationship between DII scores and the risk of elevated blood pressure( P nonlinear =0.13). The mediation analysis revealed that BMI played a partial mediating role in the association between DII scores and elevated blood pressure. The mediation effect value was 0.06 (95% CI =0.04-0.08), accounting for 44.64% of the total effect. Conclusions DII scores are associated with elevated blood pressure among primary school students in Ma anshan City, and BMI plays a partial mediating role in this association. Promoting an anti inflammatory dietary pattern and weight control in early childhood should be emphasized to reduce the incidence of hypertension among primary school students.

Objective: To investigate the emotional and behavioral problems among preschool children and the correlations with maternal parenting competence and family rearing environment, so as to provide a scientific basis and practical guidance for the physical and mental health development of preschool children. Methods: In June 2025, 660 preschool children aged 3-6 years old were selected from 10 kindergartens in Hefei, Anqing, and Tongling in Anhui Province by using a stratified cluster random sampling method. A questionnaire survey was conducted among all parents of preschool children using the Parent version of the Strengths and Difficulties Questionnaire, the Child Family Rearing Environment Scale, and the Chinese version of the Parenting Sense of Competence Scale. Pearson correlation analysis and multiple linear regression analysis were used to analyze the related factors of emotional and behavioral problems among preschool children. SPSS macro program Process 4.1 and Bootstrap method were used to test the mediating effect of family parenting environment between emotional and behavioral problems among preschool children and maternal parenting competence. Results: The detection rate of emotional and behavioral problems among preschool children was 20.15%. The total scores of family rearing environment and maternal parenting competence were negatively correlated with emotional and behavioral problems among preschool children ( r =-0.45,-0.79), and the total score of family rearing environment was positively correlated with the total score of maternal parenting competence ( r =0.43) (all P <0.01). Multiple linear regression showed that, after controlling whether being only child, parents educational level, registered residence location and other variables, family rearing environment, self efficacy and satisfaction were all negative predictors of emotional and behavioral problems among preschool children ( B =-0.07, -0.42, -0.42, all P <0.01). The mediation effect results showed that maternal parenting competence could positively predict the family rearing environment ( B =0.75), while maternal parenting competence and family rearing environment could both negatively predict emotional and behavioral problems among preschool children ( B =-0.49, -0.06 ) (all P <0.05). The Bootstrap sampling method test results showed that the effect value of the indirect effect of maternal parenting competence on emotional and behavioral problems through the family rearing environment was -0.04, and the effect proportion was 8.21 %. Conclusion Preschool children with a better family rearing environment and stronger maternal parenting competence are less likely to have emotional and behavioral problems, among which the family rearing environment has a mediating effect.

Pasteurella is a genus of zoonotic pathogens that are widely distributed in both healthy and diseased ani-mals.Reports of human infections caused by wild animal bites are rare.This paper reports the first case of Pasteu-rella multocida infection caused by a snow leopard bite in China.The strains were identified using the DL-96 Ⅱ bac-terial identification system,BRUKER automatic microbial mass spectrometer,and Autof ms 1000 mass spectrome-ter.Antimicrobial susceptibility testing was performed using the DL-96 Ⅱ bacterial assay system.After wound de-bridement,surgical incision and drainage,and combined antimicrobial treatment,the patient recovered and was dis-charged from the hospital.This paper aims to improve clinical health care workers'understanding on this bacterium.

Objective To investigate the distribution and antimicrobial resistance profiles of clinical isolates in Xi'an No.3 Hospital from 2019 to 2023.Methods Clinical isolates were collected from January 1,2019 to December 31,2023.Antimicrobial susceptibility testing was carried out according to a unified protocol of China Antimicrobial Resistance Surveillance Network using Kirby-Bauer method or automated systems.The data were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2023.Results A total of 6 621 clinical isolates were collected from 2019 to 2023,including 1 569(23.7％)strains of Gram-positive bacteria and 5 052(76.3％)strains of Gram-negative bacteria.The prevalence of methicillin-resistant S.aureus,S.epidermidis and other Staphylococcus species(except SS.pseudintermedius and S.schleiferi)was 39.0％,62.3％,and 74.4％,respectively.Methicillin-resistant strains showed much higher resistance rates to most of other antimicrobial agents than methicillin-sensitive strains.No Staphylococcus strains were found resistant to vancomycin or linezolid.E.faecium strains demonstrated much higher resistance rates to most antimicrobial agents tested than E.faecalis.The prevalence of linezolid-resistant E.faecalis and vancomycin-resistant E.faecium was 0.9％and 0.4％,respectively.The prevalence of penicillin-nonsusceptible strains(PISP+PRSP)was 5.8％in nonmeningitis S.pneumoniae isolates.The prevalence of ESBL-producing E.coli,K.pneumoniae,and P.mirabilis in Enterobacterales was 48.5％,37.8％,and 47.2％,respectively.Among Enterobacterales strains,K.pneumoniae had the highest resistance rate to imipenem(18.2％)and meropenem(17.9％).Other Enterobacterales were highly sensitive to carbapenems.The resistance rates of P.aeruginosa to imipenem and meropenem were 22.5％and 19.5％,respectively.The resistance rates of A.baumannii to imipenem and meropenem were 65.0％and 71.6％,respectively.Conclusions Antibiotic resistance is still serious in this hospital.Nearly half of the strains of E.coli,K.pneumoniae and P.mirabilis produced ESBLs.K.pneumoniae and A.baumannii showed high resistance rates to carbapenems.Antimicrobial resistance surveillance should be performed appropriately.Relevant departments need to strengthen cooperation to curb the spread of drug-resistant bacteria.

Purpose To investigate the independent risk factors for early recurrence of solitary hepatocellular carcinoma after radiofrequency ablation based on gadoxetic acid disodium(Gd-EOB-DTPA)-enhanced MRI combined with clinical features.Materials and Methods Clinical and imaging data of hepatocellular carcinoma patients who underwent radiofrequency ablation at the First Affiliated Hospital of Henan University of Chinese Medicine from January 2019 to June 2022 were retrospectively collected.All patients underwent preoperative Gd-EOB-DTPA-enhanced MRI and were followed up for up to two years post-surgery.Univariate and multivariate Cox proportional hazards regression were performed to identify independent risk factors for recurrence after radiofrequency ablation.Results A total of 58 patients were finally included,including early recurrence group(n=22)and non-early recurrence group(n=36).Multivariate Cox regression analysis revealed that preoperative alpha-fetoprotein(AFP)levels(HR=1.103,95%CI 1.008-1.206,P=0.033),arterial-phase irregular margin enhancement(HR=4.647,95%CI 1.527-14.110,P=0.007),peritumoral arterial-phase enhancement(HR=11.575,95%CI 3.575-37.478,P=0.001)and peritumoral hepatobiliary phase hypointensity(HR=5.058,95%CI 1.129-22.668,P=0.034)were independent risk factors for early recurrence.The area under the curve for AFP combined with arterial-phase irregular margin enhancement,peritumoral arterial-phase enhancement and peritumoral hepatobiliary phase hypointensity were 0.896,0.842 and 0.860,with accuracy rates of 81.0%,84.5%and 82.8%,respectively.Conclusion Preoperative serum AFP levels,arterial-phase irregular margin enhancement,peritumoral arterial-phase enhancement and peritumoral hepatobiliary phase hypointensity are independent risk factors for early recurrence after radiofrequency ablation in hepatocellular carcinoma patients.The combination of AFP and any of these MRI features significantly improves predictive efficacy.

Objective:To investigate the short-term efficacy and safety of rituximab (RTX) in children with calcineurin inhibitor (CNI) resistant steroid resistant nephrotic syndrome (SRNS).Methods:A retrospective case analysis was conducted. Thirteen children with CNI resistant SRNS who were regularly treated with RTX (375 mg/m 2 per dose (maximum dose 500 mg), 1 dose per week, a total of 4 doses) in Department of Nephrology, Children′s Hospital of Fudan University from January 2016 to December 2023 were enrolled. The general data, disease related information, urinary protein/creatinine, serum albumin, blood creatinine before RTX treatment, immunosuppressants, adverse events, and monthly urinary protein/creatinine, serum albumin, and blood creatinine indexes within 6 months after RTX treatment were collected. The changes of urinary protein/creatinine, serum albumin and estimated glomerular filtration rate (eGFR) before and after RTX at 3 and 6 months were analyzed by using paired sample t test and Wilcoxon signed-rank test. Results:Among the 13 patients, 8 were male and 5 were female. The age of disease onset was 4.0 (2.9, 6.8) years and the age of RTX treatment was 9.8 (5.9, 13.6) years. There were 8 cases of focal segmental glomerulosclerosis, 3 cases of minimal change disease and 2 cases of mesangial proliferative glomerulonephritis. No clinically significant gene variation was detected in 12 cases and the other one did not receive gene test. Before RTX treatment, 11 cases were in chronic kidney disease stage G1, and 1 case each was in stage G2 and stage G3. Ten children completed 4 doses of RTX treatment, 1 patient completed 3 doses, and 2 patients completed 2 doses. Urinary protein/creatinine in 13 children at 3 and 6 months after RTX treatment was significantly lower than baseline (0.60 (0.13, 2.04), 0.49 (0.28, 1.10) vs. 1.44 (0.76, 4.11) mg/mg, Z=-2.34, -2.34, both P<0.05), and serum albumin was significantly higher than baseline ((35±8), (34±7) vs. (30±6) g/L, t=2.30, 2.60, both P<0.05). The eGFR at 6 months after RTX treatment was not significantly different from the baseline ((110±32) vs. (113±35) ml/(min·1.73 m 2), t=-0.76, P>0.05)). No serious adverse reactions occurred in this study. Conclusion:RTX could reduce urinary protein and increase serum albumin in short-term treatment in children with CNI resistant SRNS without significant side effects.

Since May 2022, a severe global Mpox epidemic has underscored the urgent need for a preventative vaccine. On September 16, 2022, the mainland of China reported its first case of imported Mpox, which was subsequently followed by a significant rise in domestic infections commencing from June 2023. This alarming trend has escalated the likelihood of localized outbreaks and covert transmission, posing a heightened risk to public health. Notably, the United States, many European countries, and Japan have approved the use of smallpox vaccines for Mpox prevention and emergency vaccination post-exposure, based on their cross-protection efficacy. In recent years, virology research has broadened its scope to include investigations into various novel vaccine approaches, such as nucleic acid-based vaccines, protein subunit vaccines, and epitope peptide vaccines, and other related methodologies. This review offers a thorough examination of the current global landscape of Mpox prevalence, delves into the advancements in Mpox vaccine development, and highlights the progress achieved in Mpox vaccine research, serving as a valuable resource and providing technical insights essential for the effective prevention and control of Mpox.
