In the era of evidence-based medicine， the progress of medical science and technology has enriched medical diagnostic tools and treatment methods， but it has also led to the loss of medical warmth and the alienation of the doctor-patient relationships. William Osler emphasized that while medical technology advances， attention should also be paid to the practice of narrative medicine and the development of physician’s narrative literacy. The view of the physician he advocated reminds us that the core of medicine still lies in the narrative connection between doctors and patients， as well as a deep understanding of human nature. By exploring the relationship between Osler’s view of the physician and narrative medicine as well as physician’s narrative literacy， this paper analyzed the methods of cultivating physician’s narrative literacy， providing references for modern medical education and practice， and assisting in the harmony and unity of science and technology and humanity.

ObjectiveTo investigate the expression and prognostic significance of human epidermal growth factor receptor 2 （HER-2）， vascular endothelial growth factor-A （VEGF-A）， and programmed death-ligand 1 （PD-L1） in gallbladder cancer， and to provide a theoretical basis for subsequent research. MethodsA retrospective analysis was performed for the postoperative specimens and clinical data of 55 patients who underwent radical cholecystectomy for gallbladder cancer and had pathologically confirmed gallbladder adenocarcinoma in The Affiliated Hospital of Inner Mongolia Medical University from December 2017 to September 2019. Immunohistochemical staining was used to measure the expression levels of HER-2， VEGF-A， and PD-L1 in cancerous tissue and paracancerous tissue. The association between the expression of these three markers and clinical features were analyzed， as well as their impact on the prognosis of patients. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups； the chi-square test was used for comparison of categorical data between groups. The Cox regression model was used to perform the univariate and multivariate analyses of clinical factors. The Kaplan-Meier curve was used to analyze the prognosis of patients， and the Log-rank test was used for comparison. ResultsAmong the 55 patients， 15 patients （27.2%） had a high expression level of HER-2 in cancerous tissue， 23 （41.8%） had a high expression level of VEGF-A， and 18 （32.7%） had a high expression level of PD-L1， with significant differences compared with the paracancerous tissue （all P<0.05）. There was a significant difference in tumor location between the groups with different expression levels of HER-2 （P<0.05）； there were significant differences in maximum tumor diameter， degree of tumor differentiation， tumor location， N stage， peripheral organ invasion， and vascular invasion between the groups with different expression levels of VEGF-A （all P<0.05）； there were significant differences in peripheral organ invasion， vascular invasion， and disease stage between the groups with different expression levels of PD-L1 （all P<0.05）. The multivariate Cox analysis showed that preoperative CA19-9 level and HER-2 expression were independent risk factors for overall survival of patients （P<0.05）， and preoperative CA19-9 level， maximum tumor diameter， N stage， VEGF-A， and PD-L1 were independent influencing factors for progression-free survival of patients （P<0.05）. The Kaplan-Meier analysis showed that there were significant differences in overall survival and progression-free survival between the patients with high HER-2 expression and those with low HER-2 expression （P<0.05）. ConclusionHER-2， VEGF-A， and PD-L1 have an important clinical significance for patients with gallbladder cancer and are potential sites for targeted therapy.

Objective: To analyze the consumption frequency of major foods among Chinese children aged 6-17 years old, and to provide a basis for optimizing the dietary structure of children in China. Methods: Using data from the China Nutrition and Health System Survey and Application Program for Children 0-18 years old, 56 734 children aged 6-17 years old from North, Norththeast East, Central, South, Southwest and Northwest seven regions in China were selected for the study using stratified cluster random sampling from 2019 to 2021. A food frequency questionnaire was used to investigate the intake frequency of eight food groups in a month, including fresh vegetables, fresh fruits, livestock and poultry meats, aquatic products, eggs, dairy products, legumes, and cereals and potatoes. The foods were grouped according to whether they met the recommended intake criteria outlined in the Dietary Guidelines for Chinese Residents 2022. The〖KG*2〗χ2 test was used to compare the differences in the proportion of childrens intake frequency of each food group meeting the standard in different regions and age groups. Results: The proportions of Chinese children aged 6-17 years who consumed fresh vegetables and cereals and potatoes ≥3 times/d were 12.1% and 67.2%, respectively. The proportions of children who consumed fresh fruits, livestock and poultry meats, eggs and dairy products ≥1 time/d were 50.8%, 58.8%, 36.0% and 54.3%, respectively. The proportion of legumes consumed ≥4 times/week was 37.4%, and the proportion of aquatic products consumed ≥2 times/week was 39.7%. Fresh vegetables (5.5%), fresh fruits (33.1%), and dairy products (36.4%) had the lowest frequency of meeting the recommended standards in South China, and aquatic products (27.4%) and eggs (21.1%) had the lowest frequency of meeting the recommended standards in Northwest (P<0.008 3). Conclusion The overall intake frequency of fresh vegetables, fresh fruits, legumes, and dairy products are insufficient among Chinese children, with significant regional variations.

Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Objective To investigate the protective effect of Liraglutide in rats with diabetic kidney disease(DKD)by regulating the nuclear factor E2-related factor 2(Nrf2)/glutathione peroxidase 4(GPX4)ferroptosis signaling pathway.Methods Twelve male Sprague-Dawley(SD)rats were randomly divided into normal control(NC)group,DKD group,and Liraglutide treatment(Lir)group,with 4 rats in each group.The 24 hUAlb,TC,TG,LDL-C,serum creatinine(Scr),BUN,ferrous ion(Fe2+),the activity of glutathione peroxidase(GSH-Px),and malondialdehyde(MDA)were detected in each group.Hematoxylin and eosin(HE),periodic acid-Schiff(PAS),and periodic acid-silver methenamine-Masson(PASM-Masson)staining were used to observe the pathological changes of the kidneys.Immunofluorescence was performed to detect the localization and expression of reactive oxygen species(ROS)in the renal tissue.The protein expressions of Nrf2 and GPX4 were detected by Western blot.Results Compared with the NC group,the levels of 24 hUAlb,Scr,BUN,TC,TG,LDL-C,MDA,ROS,and Fe2+were increased(P＜0.05 or P＜0.01),while the expressions of GSH-Px,Nrf2,and GPX4 proteins were decreased in the DKD group(P＜0.01).Compared with the DKD group,the levels of 24 hUAlb,BUN,TC,TG,LDL-C,MDA,ROS,and Fe2+were decreased(P＜0.05 or P＜0.01),and the expressions of GSH-Px,Nrf2,and GPX4 proteins were increased in the Lir group(P＜0.01).Conclusions Liraglutide may exert a protective effect in DKD by upregulating the Nrf2/GPX4 signaling pathway and inhibiting ferroptosis.

Objective:To explore the relationship between programmed death-1(PD-1)inhibitors and cancer-related fatigue(CRF)in patients with malignant melanoma,and to identify associated influencing factors.Methods:A total of 100 patients with malignant melanoma treated at Jinan People's Hospital between April 2019 and April 2024 were included as study subjects.The Chinese version of the Piper Fatigue Scale was used to evaluate patients'fatigue levels within three months before and after the initiation of PD-1 inhibitor therapy.Results:There was a significant difference in CRF score before and after PD-1 inhibitor treatment(P<0.001).Univariate analysis showed no significant association between fatigue severity and factors such as gender,smoking history,tumor site,or PD-1 inhibitor type(all P>0.05).However,age,tumor stage,anemia,leukopenia,secondary hypothyroidism,secondary adrenal insufficiency(AI),and secondary adrenocorticotropic hormone deficiency(P<0.05 or P<0.01 or P<0.001)were significantly associated with CRF.Multivariate regression analysis identified secondary hypothyroidism,secondary AI,anemia,and leukopenia as independent risk factors for severe CRF in patients with malignant melanoma(all P<0.05).Conclusion:Adverse reactions of PD-1 inhibitors,including secondary hypothyroidism,secondary AI,anemia,and leukopenia,are independent risk factors for CRF in patients with malignant melanoma.

Objective To verify the applicability of a pig STR multiplex amplification system for detecting processed foods containing pork and their digestive samples,and to evaluate its potential in food safety and forensic biological evidence analysis.Methods DNA profiles were obtained using the pig STR amplification system from food samples with different levels of processing(raw pork,boiled pork,fried pork,and sausage)and from digestive samples(rat gastric contents).The influence of processing methods on DNA integrity was assessed.The uniformity of large-scale processed ham products,the consistency of DNA profiles from different parts of the same sample,and the DNA degradation patterns after rat digestion were examined.Results STR profiling of pig DNA was successful in all tested samples.Short fragments showed high amplification stability,while long fragment signals weakened with increasing processing complexity.In processed ham products,DNA profiles were consistent across all sampled parts,with fragment drift within±0.5 bp.Analysis of rat gastric contents showed slight DNA degradation within 2 hours;after 3 hours,long fragment signals weakened,and after 4 hours,some loci signals were lost.Conclusion The pig STR multiplex amplification system exhibits excellent performance in detecting processed pork products and their digestive samples.It can meet the requirements of food traceability and forensic biological evidence analysis for processed pork,providing new insights for the advancement of forensic testing techniques in this field.

Objective:To determine the prevalence of self-reported food allergies among children in the grasslands of North China and to analyze its associated risk factors.Methods:In this study, a cross-sectional epidemiological survey method was used to select children under 14 years old by multi-stage, stratified and random cluster sampling in the grassland ecological area of Zhangbei County, Hebei Province, China from May to July 2018. Face-to-face questionnaires were administered to gather food allergy-related information from the participants. Multivariate logistic regression analysis was used to analyze the risk factors associated with self-reported food allergy.Results:A total of 2 086 children completed the survey. The prevalence of self-reported food allergies was 22.0%(459/2 086). The prevalence of multiple food allergies (≥3 types) was 3.1%(64/2 086) versus 16.3% (341/2 086) for a single food allergy among all children. Mango allergy (6.1%, 127/2 086) was the most common, followed by peach allergy (4.1%, 85/2 086). Children who reported food allergies had a significantly higher prevalence of all 4 atopic disorders (eczema, asthma, allergic rhinitis, and allergic conjunctivitis than those without food allergies(35.73% vs. 20.65%, 5.88% vs. 2.77%, 17.86% vs. 7.38%, 16.78% vs. 10.45%, χ2 =44.663 1, 10.434 3, 45.038 3, 13.728 4, all P<0.001).Significantly associated risk factors of food allergy were found to be pollen allergy ( OR: 2.29; 95% CI: 1.80-2.92) and drug allergy ( OR: 1.53; 95% CI: 1.12-2.09). Conclusions:The prevalence of self-reported food allergies among children in the Zhangbei County area of the North China Grassland was relatively high. Pollen allergy and drug allergy are major risk factors.
