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.

ObjectiveTo understand the level of medical narrative competence among hospice care practitioners in Shanxi Province， explore its influencing factors， and provide references for carrying out targeted training and improving the medical narrative competence of the medical and nursing staff. MethodsUsing convenience sampling， a total of 102 medical and nursing staff from hospitals providing hospice care in Shanxi Province were recruited as the research subjects. Questionnaire surveys were conducted with the Self-Designed General Information Questionnaire and the Self-Rating Scale for Medical Narrative Competence as the research tools. Univariate analysis and multiple linear regression analysis were adopted to explore the level of medical narrative competence and its influencing factors among hospice care practitioners in Shanxi Province. ResultsThe total score of medical narrative competence among hospice care practitioners in Shanxi Province was （158.19±19.69）. The mean scores of all dimensions were ranked from the lowest to the highest as attention and listening， understanding and response， and reflection and representation. Univariate analysis demonstrated that working years in hospice care， daily communication frequency with patients， weekly communication duration， degree of colleague care， professional recognition， job satisfaction， and familiarity with narrative medicine constituted the influencing factors for the level of medical narrative competence among hospice care practitioners （all P<0.05）. Multiple linear regression analysis showed that working years in hospice care， degree of colleague care， and familiarity with narrative medicine had statistically significant effects on the medical narrative competence of hospice care practitioners （all P<0.05）. ConclusionAdministrators of hospice care should prioritize medical and nursing staff who lack familiarity with narrative medicine， have low degrees of colleague care， experience short working years， and possess low professional recognition and job satisfaction with hospice care work. Targeted training should be strengthened for these individuals to improve their medical narrative competence level， thereby enhancing the quality of hospice care services.

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.

Intestinal aging is central to systemic aging, characterized by a progressive decline in intestinal structure and function. The core mechanisms involve dysregulation of epithelial cell renewal and gut microbiota dysbiosis. In addition to previous results in model organisms like Drosophila melanogaster, recent studies have shown that in mammalian models, aging causes increased intestinal permeability and intestinal-derived systemic inflammation, thereby affecting longevity. Therefore, anti-intestinal aging can be an important strategy for reducing frailty and promoting longevity. There are three key gaps remaining in the study of intestinal aging: (1) overemphasis on aging-related diseases rather than the primary aging mechanisms; (2) lack of specific drugs or treatments to prevent or treat intestinal aging; (3) limited aging-specific dysbiosis research. In this review, the basic structures and renewal mechanisms of intestinal epithelium, and mechanisms and potential therapies for intestinal aging are discussed to advance understanding of the causes, consequences, and treatments of age-related intestinal dysfunction.

Objective To observe the clinical efficacy of acupotomy release therapy under the theory of sinew channels in the treatment of femoral head necrosis.Methods A total of 82 patients diagnosed with femoral head necrosis who underwent hip-preserving treatment at Beijing Hepingli Hospital from May 2020 to May 2023 were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 41 patients in each group.The control group received hip joint rehabilitation training combined with sinew channel massage therapy,while the observation group received acupotomy release therapy under the theory of sinew channels in addition to the treatment given to the control group.for 6 months of treatment.Changes in the Visual Analogue Scale(VAS)scores of pain,hip joint range of motion,and Harris scores were observed before and after treatment.Additionally,serum levels of 5-hydroxytryptamine(5-HT),substance P(SP),calcitonin gene-related peptide(CGRP),and neuropeptide Y(NPY)were compared between the two groups before and after treatment.Results(1)After treatment,the VAS scores of both groups were significantly improved(P＜0.05),and the observation group showed significantly better improvement in VAS scores compared to the control group,with a statistically significant difference(P＜0.05).(2)After treatment,the hip joint range of motion improved significantly in both groups(P＜0.05),and the observation group showed significantly better improvement in hip joint range of motion compared to the control group,with a statistically significant difference(P＜0.05).(3)After treatment,the excellent and good rate of hip joint function in the observation group was 95.12%(39/41),while it was 78.05%(32/41)in the control group.The observation group had a significantly higher excellent and good rate of hip joint function compared to the control group,with a statistically significant difference(P＜0.05).(4)After treatment,the levels of 5-HT,SP,CGRP,and NPY improved significantly in both groups(P＜0.05),and the observation group showed significantly better improvement in these levels compared to the control group,with a statistically significant difference(P＜0.05).Conclusion Acupotomy release therapy under the theory of sinew channels in the treatment of femoral head necrosis can significantly alleviate pain symptoms and improve hip joint function in patients.Its analgesic mechanism may be related to the regulation of neurotransmitter levels and the restoration of their balance.

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.

Objective:To analyze differences on characteristics of HIV/AIDS knowledge, beliefs and behavior among female college students who reported having sex in Zhejiang Province between 2018 and 2020, and provide reference for HIV/AIDS prevention and control among female college students.Methods:Cross-sectional surveys were conducted in October-November 2018 and November-December 2020 among female college students in 13 universities in 11 cities in Zhejiang Province, and female college students who self-reported having sexual intercourse in the past year were included as study subjects, with sample size estimates of 5 265 and 9 466 for the two surveys, respectively. 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 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.
