OBJECTIVE To investigate the application and influencing factors of sodium-dependent glucose transporters 2 inhibitors（SGLT-2i） in patients with heart failure with preserved ejection fraction（HFpEF） in the real world. METHODS Data from 358 patients with HFpEF who were hospitalized at the First Affiliated Hospital of Chongqing Medical University from May 2023 to May 2024 were retrospectively collected. The patients were divided into the SGLT-2i group and the non-SGLT-2i group based on whether they were prescribed SGLT-2i upon discharge. Baseline characteristics， comorbidities， and differences in drug treatment were compared between the two groups. Based on univariate analysis， multivariate Logistic regression analysis was performed to identify independent influencing factors of SGLT-2i use in patients with HFpEF， followed by further stratified analysis. RESULTS Among 358 HFpEF patients， the overall utilization rate of SGLT-2i was 33.5%. Combined with type 2 diabetes [OR＝9.063，95%CI（4.924-16.679） ] ， atrial fibrillation [OR＝3.135，95%CI（1.590-6.178） ] ， coronary artery heart disease [OR＝1.888，95%CI（1.072-3.327） ] and the use of loop diuretics [OR＝3.822， 95%CI （1.588-9.200） ] were all independent influencing factors for the use of SGLT-2i in patients with HFpEF （ P ＜0.05）. The results of the stratified descriptive analysis were consistent with those of the multivariate analysis， showing a higher utilization rate of SGLT-2i among patients with concomitant T2DM，atrial fibrillation， coronary artery heart disease， and those receiving loop diuretics （ P ＜0.05）； whereas the utilization rate of SGLT-2i was comparable across patients with different levels of renal function （ P ＞0.05）. CONCLUSIONS In the real-world clinical practice， the utilization of SGLT-2i in patients with HFpEF remains suboptimal， and treatment coverage still needs to be improved. Their use of SGLT-2i is primarily influenced by the presence of type 2 diabetes， atrial fibrillation， coronary artery heart disease， and the use of loop diuretics.

ObjectiveThis study aimed to investigate the anti-Mycoplasma pneumoniae (MP) activity of luteolin and elucidate its underlying mechanisms. MethodsLuteolin was identified as the primary active compound from the polyphenol extract ofF. diotrys using network pharmacology. Its efficacy was evaluated against two MP strains: the standard strain M129 and the multidrug-resistant strain M19. A modified culture medium with visual characteristics was employed to determine the minimum inhibitory concentration (MIC) of luteolin. The expression of key proteins involved in MP growth and pathogenicity was assessed by qRT-PCR following luteolin treatment. Additionally, the viability of A549 cells infected with MP was compared between luteolin-treated and untreated groups. In vivo anti-MP activity was evaluated using a mouse model, and the expression of inflammatory cytokines in lung tissues was analyzed. ResultsLuteolin effectively inhibited both MP strains, with MIC₉₀ values of 100 mg/L for M19 and M129. Treatment with luteolin significantly downregulated the expression of adhesion proteins P1 and P30 in both strains. However, the expression of P65, HMW3, TrmB, and CARDS TX was reduced only in the M19 strain following luteolin intervention. Luteolin also enhanced the growth and viability of A549 cells infected with MP. In the mouse model, luteolin treatment resulted in steady weight gain and was well tolerated. The bacteriostatic rate of luteolin in lung tissues was 50.7%, significantly higher than the 25.2% observed in the roxithromycin group. Furthermore, luteolin reduced the expression of inflammatory factors, including IL-6, TNF-α, and HMGB1, in MP-infected mice. ConclusionLuteolin effectively and safely inhibits the proliferation and pathogenicity of MP, particularly the drug-resistant M19 strain, by downregulating the expression of toxicity-associated proteins (P1, P30, P65, HMW3, TrmB, CARDS TX) and modulating host inflammatory responses. These findings suggest that luteolin may offer a novel therapeutic strategy for treating MP infections, especially those caused by drug-resistant strains.

Background: This study was performed to characterize the incidence, costs, and risk factors associated with renal and cardiovascular adverse outcomes following primary percutaneous coronary intervention (pPCI) in patients with ST-elevation myocardial infarction (STEMI). Methods: Patients with STEMI who underwent pPCI using iso-osmolar contrast were enrolled at 39 centers. The incidence of acute kidney injury (AKI) and major adverse renal and cardiovascular events (MARCE) was analyzed, as well as inpatient costs. Logistic regression analysis was performed to identify risk factors. Results: Among 2,293 patients, the incidence of AKI and MARCE within 72 hours post-pPCI was 4.14% (n = 95) and 4.40% (n = 101), respectively. AKI and/or MARCE were associated with systolic blood pressure (AKI: odds ratio [OR], 1.009; 95% confidence interval [CI], 1.000–1.018), hypertension (AKI: OR, 1.815; 95% CI, 1.133–2.906; MARCE: OR, 1.760;95% CI, 1.118–2.769), anterior wall infarction (AKI: OR, 1.895; 95% CI, 1.196–3.004; MARCE:OR, 1.939; 95% CI, 1.240–3.032), Killip class (AKI: OR, 1.465; 95% CI, 1.117–1.922; MARCE:OR, 1.467; 95% CI, 1.131–1.903), and serum creatinine (SCr; MARCE: OR, 1.006; 95% CI, 1.000–1.012). Hospitalization costs for patients with STEMI who developed AKI or MARCE were significantly higher than for those without AKI (9,595 ± 5,795 vs. 8,279 ± 3,872 USD, P = 0.003) or without MARCE (9,890 ± 5,616 vs. 8,255 ± 3,859 USD, P < 0.001). Conclusions In patients with STEMI undergoing pPCI with iso-osmolar contrast, the incidence of AKI and MARCE was associated with higher hospitalization costs. Systolic blood pressure, hypertension, anterior wall infarction, Killip class, and SCr were identified as risk factors for these outcomes.

Objective: To investigate the association of special family structure and physical activity with psychological sub health among secondary vocational school students, so as to provide reference to inform mental health promotion in the population. Methods: From September to December 2024, a convenience sample was drawn from 16 schools including 5 141 secondary vocational school students across 8 provinces (municipalities) in China (Fujian, Chongqing, Guangdong, Guangxi, Hubei, Jiangxi, Shanghai, Zhejiang). A self developed questionnaire, Multidimensional Sub health Questionnaire of Adolescents and International Physical Activity Questionnaire Short Form were used to investigate and evaluate basic information, family structure, psychological sub health status and physical activity. Descriptive statistics and Logistic regression analysis were performed to explore relationships of special family structures and physical activity with psychological sub health in secondary vocational school students. Results: The detection rate of psychological sub health among secondary vocational school students was 11.0%. The reporting rates for secondary vocational school students who lost their father or lost their mother, whose parents divorced, whose parents remarried, and those from special family structures were 2.8%, 0.8%, 11.8%, 3.9%, and 14.7%, respectively. Moreover, the detection rates of psychological sub health and its sub dimensions significantly differed among secondary vocational school students grouped by family type (divorced parental families, remarried parental families and special family structures)( χ 2=5.90-22.67, all P <0.05). Binary Logistic regression indicated that maternal bereavement was associated with a higher risk of conduct problems [ AOR ( 95% CI )= 2.90(1.15-7.33)], and parental divorce was associated with a higher risk of psychological sub health ( AOR= 2.71 , 95%CI =1.04- 7.06 ) among secondary vocational school students (both P <0.05). Interaction analysis showed that both students with a special family structure and insufficient physical activity [ AOR (95% CI )=1.99(1.44-2.75)] and those with a non-special family structure and insufficient physical activity [ AOR (95% CI )=1.81(1.48-2.22)] were associated with increased risks of psychological sub health among secondary vocational school students (both P <0.01). Conclusion Special family structure and physical activity are associated with psychological sub health among secondary vocational school students; early identification and assessment based interventions for those with a special family structure should be strengthened, while school based physical activity should be implemented to increase physical activity levels,thereby reducing the risk of psychological sub health.

Among them, compound 1 was a new compound, and compounds 3–10 were isolated from the genus Cyclocarya for the first time.

Improving the nitrogen use efficiency (NUE) of Brassica napus is of significant importance for achieving the national goal of zero growth in chemical fertilizer application and ensuring the green development of the rapeseed industry. This study aims to explore the effects of the nitrate transporter gene BnaNRT1.5s on the nitrogen transport and NUE of B. napus, providing excellent genetic resources for the development of nitrogen-efficient B. napus varieties. The spatiotemporal expression of BnaA05.NRT1.5 as a key nitrogen responsive gene was profiled by qRT-PCR at different growth stages and for different tissue samples of B. napus 'Westar'. Subcellular localization was employed to examine its expression pattern in the cells. Additionally, CRISPR/Cas9 was used to create BnaNRT1.5s knockout lines, which were subjected to hydroponic experiments under high nitrogen (12.0 mmol/L) and low nitrogen (0.3 mmol/L) conditions. After the seedlings were cultivated for 21 days, root and shoot samples were collected for weighing, nitrogen content determination, xylem sap nitrate content assessment, and calculation of total nitrogen and NUE. The B. napus nitrate transporter BnaA05.NRT1.5 was localized to the cell membrane. During the seedling and early bolting stages, BnaA05.NRT1.5 was predominantly expressed in roots, while it was highly expressed in old leaves and mature silique skin during the reproductive stage. Compared with the wild type, the mutant BnaNRT1.5s showed significant increases in the dry weight and total nitrogen of seedlings under both high and low nitrogen conditions. Under low nitrogen conditions, NUE in the roots of BnaNRT1.5s significantly improved. Notably, under both high and low nitrogen conditions, the nitrate content in the shoots of BnaNRT1.5s decreased significantly, while that in the roots increased significantly, resulting in a significantly decreased shoot-to-root nitrate content ratio. BnaNRT1.5s is involved in regulating the transport of nitrate from the roots to the shoots, and its mutation enhances nitrogen absorption and utilization in B. napus seedlings, promoting seedling growth. This study not only provides references for understanding the physiological and molecular mechanisms by which BnaNRT1.5s regulates NUE but also offers valuable genetic resources for improving NUE in B. napus.

Objective:To analyze the distribution of tumor necrosis factor-alpha（TNF-α）308 gene loci polymorphism in children with febrile seizures（FS）and to explore the correlation between TNF-α 308 gene polymorphisms and FS in children.Methods:A total of 320 children diagnosed with FS in the Department of Emergency，Shanghai Children's Hospital from September 1st，2020 to June 30th，2021 were enrolled as the study subjects，which were divided into simple febrile seizures（SFS）group（232 cases）and complex febrile seizures（CFS）group（88 cases）based on their clinical characteristics，and the clinical characteristics and laboratory indexes of the two groups were compared. Children with no history of convulsions were selected as the control group（160 cases）. The high-resolution melting and gene sequencing technology were used to analyze the polymorphism of TNF-α 308 gene in each group and the distribution of different gene types and allele frequencies among the groups was compared. A multivariate Logistic regression model was constructed to analyze the relationship between TNF-α 308 gene polymorphism and FS.Results:The age，mean corpuscular volume，mean corpuscular hemoglobin and platelet distribution width of the CFS group were significantly higher than those in the SFS group，and the difference was statistically significant（all P<0.05）.There was no significant difference in gender distribution，family history of FS，history of FS，body temperature at time of convulsions，WBC，Hb，CRP and PLT between the two groups（all P>0.05）.The genotype frequency distribution of TNF-α 308 polymorphism in the three groups was in line with the Hardy-Weinberg equilibrium（ P>0.05）.The AA genotype of TNF-α 308 locus was not detected in the study.Compared with the control group［17 cases（10.6%）］，the distribution proportion of GA genotype in the CFS group［22cases（25.0%）］and the SFS group［52cases（22.4%）］was increased，and the difference was statistically significant（ χ2＝11.126， P＝0.004）；Compared with the control group［17 frequencies（5.3%）］，the frequency distribution proportion of allele A in the CFS group［22 frequencies（12.5%）］and SFS group［52 frequencies（11.2%）］was also increased，and the difference was statistically significant（ χ2＝9.960， P＝0.007）. Adding control factors such as gender，age，family history of FS，body temperature at time of convulsions and blood routine markers，the multivariate Logistic regression model was constructed to show that there was no statistically significant association between TNF-α 308 genotype and CFS in children（ OR＝1.805，95% CI：0.926~3.519， P＝0.083）. Conclusion:In this study，there was no significant correlation between TNF-α 308 gene loci polymorphism and CFS in children.

Objective To investigate the relationship between the levels of macrophage migration inhibito-ry factor(MIF),lipoprotein-associated phospholipase A2(Lp-PLA2)and chemokine CC motif ligand 3(CCL3)in peripheral blood and severity of disease and complication of acute kidney injury in neonatal sepsis.Methods A total of 112 children with NS admitted to this hospital from May 2021 to May 2024 were selected as the research objects.According to the neonatal acute physiology score Ⅱ(SNAP-Ⅱ score),they were di-vided into mild group(71 cases)and severe group(41 cases),and according to whether the children were complicated with AKI,they were divided into AKI group(47 cases)and non-AKI group(65 cases).In addi-tion,112 healthy neonates who underwent physical examination in the hospital during the same period were selected as the control group.The levels of MIF,Lp-PLA2 and CCL3 in peripheral blood were detected in each group.Pearson correlation analysis was used to analyze the correlation between the levels of MIF,Lp-PLA2 and CCL3 in peripheral blood and the severity of NS.Multivariate Logistic regression was used to analyze the influencing factors of AKI in children with NS.The receiver operating characteristic(ROC)curve was drawn to evaluate the predictive value of peripheral blood MIF,Lp-PLA2 and CCL3 for the severity of NS and the complication of AKI in NS.Results The levels of MIF,Lp-PLA2 and CCL3 in the severe group were higher than those in the mild group and the control group(P<0.05),and those in the mild group were higher than those in the control group(P<0.05).The severe group had a significantly higher SNAP-Ⅱ score than the mild group(P<0.05).The levels of MIF,Lp-PLA2 and CCL3 in peripheral blood of NS children were posi-tively correlated with SNAP-Ⅱ score(r=0.512,0.463,0.547,P<0.05).The area under the curve(AUC)of peripheral blood MIF,Lp-PLA2 and CCL3 in the diagnosis of severe NS was 0.782,0.772 and 0.753,respec-tively.The AUC of combined diagnosis was 0.888,which was higher than that of individual indicators(P<0.05).The levels of MIF,Lp-PLA2 and CCL3 in AKI group were higher than those in non-AKI group(P<0.05).Neonatal asphyxia,high levels of MIF,Lp-PLA2,and CCL3 were risk factors for AKI in children with NS(P<0.05).The AUC of MIF,Lp-PLA2 and CCL3 in predicting AKI in children with NS were 0.770,0.759 and 0.757,respectively.The AUC of the combined prediction of MIF,Lp-PLA2 and CCL3 was 0.910,which was higher than that of each index alone(P<0.05).Conclusion The levels of MIF,Lp-PLA2 and CCL3 in peripheral blood of children with NS are increased,which are closely related to the aggravation of NS and the development of AKI.The combined detection of MIF,Lp-PLA2 and CCL3 has a high value in the as-sessment of the severity of NS and the risk of AKI.

Objective:To analyze the relevant factors affecting treatment compliance in infertile patients with mycoplasma infection, construct a nomogram prediction model and validate it.Methods:In this case-control study, we retrospectively analyzed the clinical data of 400 infertile patients who attended the Department of Reproduction of Ganzhou Maternal and Child Health Hospital, Jiangxi Province from April 2022 to March 2024. They were divided into modeling group ( n=280) and validation group ( n=120) according to the 7∶3 principle with random number method, and further divided into complete compliance subgroup and unstable compliance subgroup based on different levels of compliance. Multiple logistic regression model was used to analyze the risk factors affecting treatment adherence in infertile patients with mycoplasma infection, variance inflation factor was used to assess the collinearity of the independent variables and to construct a columnar plot prediction model, and the validation and predictive efficacy of the columnar plot model were assessed by calibration curves and decision curves, respectively. The validation and predictive efficacy of the column chart model were evaluated by calibration curve and decision curve respectively. Results:In the modeling group, there was no significant statistical difference between the fully compliant group and the unstable compliant group in terms of body mass index, place of residence, occupation, settlement form, and attitude of medical staff (all P>0.05). Age in the unstable adherence subgroup [(33.22±3.20) years], proportion of junior high school and below in education [36.81% (67/182)], proportion of average monthly disposable amount ≤2 000 yuan [36.81% (67/182)], proportion of poor disease awareness [62.09% (113/182)], and infertility related stress scale (IRSS) scores (45.60±17.14) were higher than those in the full adherence subgroup [(31.36±3.24) years, P<0.001; 19.39% (19/98), P=0.003; 16.33% (16/98), P<0.001; 28.57% (28/98), P<0.001; 37.64±16.69, P<0.001]. The receiver operating characteristc curve analysis results showed that the optimal cutoff values for age and IRSS score were 32 years old and 42 points, respectively. The results of logistic multiple regression model showed that: age ( OR=1.453, 95% CI: 1.260-1.794, P=0.002), education level ( OR=1.386, 95% CI: 1.185-1.564, P<0.001), average monthly disposable amount ( OR=1.081, 95% CI: 1.002-1.246, P=0.023), disease awareness level ( OR=1.827, 95% CI: 1.390-2.359, P<0.001), and average monthly disposable amount ( OR=1.081, 95% CI: 1.002-1.246, P=0.023), disease awareness ( OR=1.827, 95% CI:1.390-2.359, P<0.001), and IRSS score ( OR=1.590, 95% CI: 1.255-1.902, P=0.006) were independent risk factors affecting treatment adherence in infertile patients with mycoplasma infection. The modeling group C-index was 0.872 (0.816-0.927), the intercept (-0.004) and slope (0.995) of the calibration curve were close to the desirable values of 0 and 1, the Brier score was 0.017, and thresholds between 0.37 and 0.96 provided a net clinical benefit. The C-index of the test model set was 0.816 (0.736-0.896), the intercept (-0.007) and slope (1.015) of the calibration curve were close to the ideal values of 0 and 1, the Brier score was 0.013, and the threshold value provided a net clinical benefit when the threshold value ranged from 0.21 to 0.98, and the H-L goodness-of-fit test showed that χ 2=7.36, P=0.499, and the constructed predictive model for the column line graphs had good discrimination and consistency. Conclusion:Age, educational level, monthly average disposable income, disease awareness, and IRSS score are the relevant factors affecting treatment compliance in infertile patients with mycoplasma infection. The nomogram prediction model constructed in this study based on those relevant factors has a good predictive value for treatment compliance in infertile patients with mycoplasma infection, and can provide certain reference for clinical intervention measures.
