ObjectiveTo explore the effect and mechanism of Jianpi Xiaoai prescription （JPXA） in ameliorating the 5-fluorouracil （5-FU） resistance of colon cancer. MethodsA HCT116/5-FU resistant cell line was established. Different concentrations （10%， 15%， 20%） of JPXA-containing serum and drug-free serum were used for intervention， and 10% fetal bovine serum （10% FBS）， fibroblast growth factor receptor （FGFR） inhibitor （AZD4547）， and recombinant fibroblast growth factor 2 （FGF2） were set as the control groups. Sensitive HCT116 cells were used in the FGF2 group， while HCT116/5-FU cells were used in other groups. Drug resistance， the level of FGF2 in the cell culture medium， the mRNA level of FGF2 in cells， and the protein levels of FGF2/FGFR and phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） were determined. The drug-resistant cells were transplanted into the axilla of nude mice to establish a tumor model. The modeled mice were allocated into model， JPXA （15 g·kg^-1）， 5-FU （0.02 g·kg^-1）， JPXA+5-FU （15 g·kg^-1+0.02 g·kg^-1）， AZD4547 （0.012 5 g·kg^-1）， and AZD4547+5-FU （0.012 5 g·kg^-1+0.02 g·kg^-1） groups. The tumor growth and the protein levels of FGF/FGFR and PI3K/Akt in each group were observed. ResultsThe survival rate of HCT116/5-FU cells decreased in all the JPXA groups with different concentrations. The cell survival rate was decreased most obviously in the 20% JPXA group. The level of FGF2 in the cell culture medium and the mRNA level of FGF2 in cells of each JXPA group decreased， and the decrease was the most significant in the 20% group （P<0.01）. HCT116/5-FU cells showed up-regulated protein levels of FGF2 and phosphorylated fibroblast growth factor receptor 1 （p-FGFR1）， but down-regulated protein level of FGFR1 （P<0.01）. JPXA down-regulated the expression of FGF2 and p-FGFR1 and up-regulated the expression of FGFR1 （P<0.05）. In addition， JPXA down-regulated the expression levels of phosphorylated protein kinase B （p-Akt） and phosphorylated mammalian target of rapamycin （p-mTOR）， while up-regulating the expression levels of Akt and Bcl-2-asociated death promoter （Bad） （P<0.05）. Animal experiments showed that the JPXA combined with 5-FU significantly inhibited the growth of drug-resistant tumors， reduced the protein levels of FGF2， p-FGFR1， phosphorylated phosphatidylinositol-3-kinase （p-PI3K）， p-Akt， and p-mTOR， and increased the expression of Bad. It indicated that JPXA can inhibit the FGF2/FGFR1 signaling in colon cancer and regulate PI3K/Akt and downstream signaling pathways. ConclusionJPXA can ameliorate the chemotherapy resistance of colon cancer through down-regulating FGF2 expression and inhibiting the activation of the PI3K/Akt signaling pathway.

Objective To analyze the influencing factors of health behaviors in stroke patients,and explore the chain mediating effects of self-efficacy and e-health literacy between the perception of stroke recurrence risk and health behaviors in stroke patients,providing a reference for strengthening the health behavior and reducing recurrence risk in stroke patients.Methods 249 stroke patients were selected as the research objects from March to September 2024 in a tertiary hospital in Shanghai,China.Patients were surveyed using General Information Questionnaire,Stroke Recurrence Risk Perception Scale,Stroke Health Behavior Scale(HBS-SP),Chronic Disease Self-Efficacy Scale(CDSES),and the e-health Literacy Scale(e-HEALS).Pearson correlation analysis was used to explore the correlations among various variables,and SPSS 26.0 software macro program Process Model 6 was used to conduct chain mediation model test.Results The scores of Recurrence Risk Perception,HBS-SP,CDSES and e-HEALS of stroke patients were(42.88±6.48)scores,(68.32±14.13)scores,(6.87±1.55)scores and(27.76±6.06)scores,and all the variables were positively correlated(P<0.01).The mediating effect model showed that self-efficacy and e-health literacy played a chain mediating role in the recurrence risk perception and health behavior in stroke patients,with an effect size of 0.488,accounting for 37.22%of the total effect.Conclusions The recurrence risk perception and health behavior of stroke patients are both at a moderate level.In the future,we can establish a mobile management platform to provide comprehensive health management for stroke patients.Further exploration of strategies to enhance stroke patients'self-efficacy and channels for online health education could be pursued to improve their health behaviors.

Objective:To investigate the methods and skills required for the safe and swift removal of primary or secondary sacral tumors located between the second (inclusive) and fourth sacral vertebrae.Methods:The clinical images, pathology reports, surgical procedures, operation durations, intraoperative bleeding volumes, and postoperative functional follow-up data of 26 patients undergoing sacral tumor resection at the First Affiliated Hospital of Zhengzhou University and Xinjiang Production and Construction Corps Hospital between May 2020 and February 2025 were retrospectively examined. Additionally, the safety measures for sacral tumor resection and techniques for expedited specimen removal were evaluated.Results:According to magnetic resonance imaging (MRI) findings, all 26 patients presented with sacral tumors located between the second (inclusive) and fourth sacral vertebrae. Specifically, 9 patients were diagnosed with primary sacral tumors, pathologically confirmed as chordomas, while 17 patients had secondary sacral tumors. Among the secondary tumor cases, 12 were attributed to recurrent rectal cancer invading the sacrum, and 5 were due to malignant teratomas invading the sacrum. The 26 patients underwent a treatment strategy that began with managing the relationship between the internal iliac artery, vein branches, and the tumor, followed by the resection of the sacrum. During surgery, the bilateral sciatic foramina were accurately positioned, and the presacral fascia was dissected subsequent to the fracture of the sacrum. Among the 26 patients, 9 underwent sacral tumor resection directly through the posterior sacral approach. The average operation time for these patients was (71.1±4.9) minutes, with average blood loss of (186.7±72.8) milliliters. On the other hand, 17 patients underwent sacral tumor resection by transitioning from the supine position to the prone knife position through a combined abdominal and sacral approach. The average operation time for this group was (213.5±19.3) minutes, with average blood loss of (480.0±93.0) milliliters, significantly longer than that of the posterior sacral approach. The follow-up period ranged from 1 to 48 months, with a median of 20 months, ending on March 31, 2025. During this time, 26 patients achieved autonomous defecation with the aid of medication. None of the patients reported any functional movement disorders or pain in their lower limbs. It was observed that two out of the 26 patients developed distant metastasis, while the remaining 24 patients survived without any tumors.Conclusion:By pretreated the relationship between the internal iliac vessels and sacral tumors prior to resecting sacral tumors, utilizing the approach of initially fracturing the sacrum followed by rupturing the presacral fascia, the tumor can be entirely eliminated, resulting in a brief surgical procedure, reduced intraoperative bleeding, and minimal postoperative complications.

The factors related to the change of relevant characteristics of the two survey subjects were analyzed. The χ2 test was used for univariate analysis and logistic regression model was used for multivariate analysis.Statistical analyses were performed with SPSS 23.0 software. Results:Of the 17 354 and 20 675 female college students surveyed in 2018 and 2020, respectively, the proportion who self-reported having had sex in the past year was 6.56% (1 139/17 354) and 4.19% (866/20 675). Multivariate logistic regression analysis showed that compared with female college students in 2018, the students who have sexual behaviour, receiving health education class by their university in the past year (a OR=1.57, 95% CI:1.29-1.91), receiving HIV testing promotion by the university in the past year (a OR=2.59,95% CI:2.13-3.14), receiving self-assessment of HIV risk by the university in the past year (a OR=2.97,95% CI:2.43-3.65), high self-efficacyfor condom use (a OR=2.00, 95% CI:1.66-2.41), receiving voluntary counseling and HIV testing (VCT) (a OR=1.81,95% CI: 1.41-2.87), perceived risk of HIV infection (a OR=2.44, 95% CI:1.32-4.54), using condoms whenever having casual sexual behaviour in the past year (a OR=3.35,95% CI:1.66-6.77) were significantly higher in 2020. Conclusions:Compared with female college students in 2018, the proportion of female college students who self-reported sexual activity decreased slightly in 2020, and the proportion of receiving HIV/AIDS lectures or health education classes, the proportion of self-rated at risk of HIV infection, the proportion of receiving VCT, the proportion of using condoms with very high confidence in self-efficacy and condom use had an increased.

Objective:To explore the latent profiles of work withdrawal behaviors of junior nurses and their relationship with workplace social capital.Methods:Using the convenience sampling method, from July to August 2023, 348 junior nurses from five Class Ⅲ and seven ClassⅡ public hospitals in Ningxia Hui Autonomous Region were selected as the research objects. They were investigated with a General Information Questionnaire, the Work Withdrawal Behavior Scale, and the Workplace Social Capital Scale. Latent profile analysis was used to explore the categories of work withdrawal behaviors of junior nurses, and the differences in workplace social capital levels among junior nurses of different categories were compared.Results:A total of 348 questionnaires were recovered online in this survey, and 342 questionnaires were valid, with a valid rate of 98.3%. The work withdrawal behaviors of 342 junior nurses could be divided into three latent profiles, including 246 junior nurses (71.9%) in the low psychological-low behavioral withdrawal group, 81 junior nurses (23.7%) in the high psychological-low behavioral withdrawal group, and 15 junior nurses (4.4%) in the high psychological-high behavioral withdrawal group. The results of the unordered multinomial Logistic regression analysis showed that gender, whether they love nursing work or not, the average number of night shifts per month, the workplace social capital, and working years were the influencing factors of the work withdrawal behaviors of junior nurses ( P<0.05) . There were statistically significant differences in the workplace social capital among the three categories of junior nurses ( H=83.82, P<0.01) . Conclusions:There are three categories of work withdrawal behaviors among junior nurses, and there are differences in workplace social capital among junior nurses of different categories. Nursing managers should intervene and support junior nurses according to the characteristics of different categories to improve their workplace social capital levels.

Walker and Avant's concept analysis method was used to analyze the concept of proactive health behavior.Results:A total of 46 articles related to proactive health behavior were included. Proactive health behavior encompasses five key attributes: self-initiation, long-term persistence, multidimensional integration, future orientation, and overcoming barriers. Antecedents include individual factors, supportive factors, and environmental factors. Outcomes include promoting individual health and improving quality of life, enhancing personal health literacy, reducing disease burden, and fostering a proactive health atmosphere.Conclusions:The concept attributes of proactive health behavior were clarified through concept analysis. Future researchers may develop proactive health behavior assessment tools and construct intervention strategies based on their connotation.

Objective:To investigate the disease burden, clinical characteristics and independent risk factors affecting in-hospital outcomes of children with congenital heart disease (CHD) combined with heart failure (HF) in China.Methods:(1) Descriptive study: based on the global burden of disease study 2021, available data on children under 15 years of age with CHD and HF in China from 1990 to 2021 were collected. The prevalence and trends in different age subgroups (<1 year, 1-<2 years, 2-<5 years, 5-<10 years, 10-<15 years) were analyzed, and the annual percentage change (EAPC) was estimated using linear regression. (2) Retrospective cohort study: a total of 1 062 children with CHD and HF from a multicenter study on pediatric HF in China were included. The children were divided into two groups:<2 years group and 2-<18 years group. Data on demographics, clinical features, diagnosis, treatments, and in-hospital outcomes were analyzed. Mann-Whitney U test and chi-square test were used for group comparisons.Multivariable Logistic regression was applied to identify factors influencing outcomes (in-hospital mortality and adverse cardiovascular events). Results:(1) From 1990 to 2021, the number of children with CHD and HF in China increased from 333 000 (95% uncertainty interval ( UI) 271 000-405 000) to 368 000 (95% UI 296 000-459 000), a growth of 10.8% (95% UI 5.0%-16.6%). Concurrently the prevalence rate increased from 104.5 (95% UI 85.1-127.3) per 100 000 to 142.0 (95% UI 114.0-176.8) per 100 000, a growth of 35.9% (95% UI 28.7%-43.0%), with an EAPC of 1.5% (95% CI 1.2%-1.8%). Although the number of cases in the<1 year and 1-<2 years groups decreased by 41.0% and 25.6%, respectively, the prevalence in all age groups showed an upward trend:<1 year EAPC 0.6% (95% CI 0.5%-0.7%); 1-<2 years EAPC 0.9% (95% CI 0.8%-1.0%); 2-<5 years EAPC 1.2% (95% CI 1.0%-1.4%); 5-<10 years EAPC 1.5% (95% CI 1.2%-1.8%); 10-<15 years EAPC 2.1% (95% CI 1.9%-2.3%). (2) The multicenter study revealed that among 1 062 hospitalized children, 528 (49.7%) were male and 534 (50.3%) were female, with the age at admission of 5.4 (2.2,18.2) months. The majority of the children (77.9%, 827/1 062) were under 2 years of age, whereas 22.1% (235/1 062) were aged between 2-<18 years. Children with complex congenital heart defects accounted for the highest proportion (48.6%, 516/1 062), while those with isolated CHD made up 31.5% (335/1 062). Statistically significant differences were observed in several variables in demographics, clinical features, diagnosis, treatments, and outcomes between the two age groups (all P<0.05). The use of renin-angiotensin-aldosterone system inhibitors (41.1%, 436/1 062) and beta-blockers (8.7%, 92/1 062) was lower in hospitalized children with CHD and HF. Logistic regression identified complex CHD ( OR=7.73, 95% CI 2.24-26.63; OR=3.17, 95% CI 1.92-5.23), pulmonary hyperperfusion ( OR=2.15, 95% CI 1.01-4.18; OR=2.00, 95% CI 1.35-2.97), left ventricular ejection fraction<55% ( OR=2.13, 95% CI 1.08-4.21; OR=2.80, 95% CI 1.45-5.56), arterial oxygen partial pressure ( OR=0.99, 95% CI 0.98-0.99; OR=0.99, 95% CI 0.98-0.99), and serum calcium levels ( OR=0.31, 95% CI 0.17-0.58; OR=0.42, 95% CI 0.28-0.62) as independent risk factors for in-hospital mortality and cardiovascular events. Conclusions:The disease burden of CHD combined with HF in China has shown a continuous upward trend from 1990 to 2021, with higher growth rates in older age groups. Complex CHD, pulmonary hyperperfusion, left ventricular ejection fraction <55%, arterial oxygen partial pressure, and serum calcium concentration are independent risk factors for in-hospital mortality and cardiovascular events.

Objective To explore the relationship between biofilm formation ability and virulence of vari-ous drug-resistant strains of Staphylococcus aureus(SA)in bloodstream infections.Methods A total of 42 strains of bloodstream infection SA were collected and identified and tested for drug sensitivity using the BDM50 automatic bacterial identification drug susceptibility system.The biofilm formation ability was deter-mined by crystal violet staining.The virulence was evaluated by detecting extracellular lipase,extracellular protease,and hemolysin,as well as conducting a toxicity test with Galleria mellonella larvae.Results Among the 42 strains of bloodstream infection SA,there were 16 strains(38.10%)of methicillin-resistant Staphylo-coccus aureus(MRSA).Among the 42 bloodstream infected SA strains,25 strains(59.50%)had the ability to form biofilms,among which there were 18 strains of methicillin-sensitive Staphylococcus aureus(MSSA)and 7 strains of MRSA.Among the 42 SA strains with bloodstream infection,37 strains(88.10%)produced hemolysin,18 strains(42.90%)produced extracellular protease,and no strains produced extracellular lipase.The Galleria mellonella larvae toxicity test showed that MRSA had stronger virulence than MSSA.Conclusion Compared with MSSA,MRSA has a higher proportion of extracellular enzymes produced,stronger virulence,and relatively weaker ability to form biofilms.
