Medical humanities consistently run through the entire process of medical development and educational reform. However， with the increasingly prominent dominance of evidence-based medicine in clinical practice， the medical humanities have gradually been weakened in both medical education and clinical practice. Narrative medicine， through telling and listening to patients’ stories， enhances healthcare professionals’ empathy， fosters doctor–patient communication， and facilitates a return to the humanistic essence of medical education and clinical practice. By sorting out and reviewing related literature and developmental trends both at home and abroad， this paper pointed out the existing structural problem of an imbalance between technological priority and humanistic care in medical education， focusing on how to achieve an effective integration of medical humanities and narrative medicine in medical education. This paper also systematically analyzed the significance of both medical humanities and narrative medicine in the medical education system and proposed promoting the deep embedding of narrative medicine in medical education from three entry points， namely， curriculum integration， interdisciplinary collaboration， and the construction of teaching evaluation systems. The aim was to provide theoretical support and practical experience for medical education reform， foster the coordinated development of professional competence and humanistic spirit among medical talents， and truly achieve the goal of cultivating well-rounded medical talents.

OBJECTIVE To investigate the effects and mechanisms of oliceridine fumarate （TRV130） in improving postoperative cognitive dysfunction （POCD） in elderly rats based on the Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB） pathway. METHODS Rats were randomly divided into the control group （normal saline）， the model group （normal saline）， the TRV130 group （2.8 mg/kg）， the TLR4/NF-κB pathway inhibitor （TAK-242） group （3 mg/kg）， the β -arrestin inhibitor （Barbadin） group （3 mg/kg）， and the traditional opioid drug （morphine） group （2.8 mg/kg）， with 15 rats in each group. Except for the control group， POCD models were established in all other groups. From the first day after surgery， drugs/normal saline were administered via caudal vein injection once daily for 3 consecutive days. After the last administration， the pathological damage of hippocampal tissue was observed； the cognitive function， serum inflammatory factor levels， hippocampal neurons apoptosis rate， and the expression of ionized calcium-binding adapter molecule 1 （Iba-1）， glial fibrillary acidic protein （GFAP）， and TLR4/NF-κB pathway-related mRNA and protein in hippocampal tissue were detected. RESULTS In the model group， the neurons in the CA1 region of the hippocampus were disordered and sparse， with decreased number， pyknotic and fragmented nuclei accompanied by inflammatory cell infiltration. Compared with the control group， the escape latency， serum levels of tumor necrosis factor α （TNF-α）， interleukin-6 （IL-6）， and IL-1β， hippocampal neurons apoptosis rate， average fluorescence intensities of Iba-1 and GFAP， mRNA expression levels of TLR4 and NF-κB p65， and their protein expression/phosphorylation levels in hippocampal tissue were significantly increased/elevated in the model group （ P ＜0.05）； the time spent in the target quadrant and the number of platform crossings were significantly shortened/decreased （ P ＜0.05）. Compared with the model group， the cognitive function， pathological， inflammatory， and apoptosis-related indicators were significantly improved in the TRV130 group， TAK-242 group， and Barbadin group （ P ＜0.05）； the mRNA expression levels of TLR4 and NF-κB p65 and their protein expression/phosphorylation levels were significantly decreased in the TRV130 group and TAK-242 group （ P ＜0.05）. CONCLUSIONS TRV130 may improve POCD in elderly rats by inhibiting the TLR4/NF-κB pathway and alleviating postoperative central nervous system inflammatory responses.

Construction of a compact county medical community is an important measure to deepen the reform of the medical and health system, promote the downward flow of medical resources, and enhance the capacity of primary medical services. Building and improving the county medical community rehabilitation medical service system is of great significance for optimizing the allocation of medical resources and providing patients with full-cycle and all-round rehabilitation services. Starting from March 2019, Ningbo had explored the construction of a rehabilitation service system based on the compact county medical community, which combined the collaborative linkage of three levels of institutions and the deep empowerment of digital technology. This practice strengthened the digital infrastructure to deliver smart healthcare, facilitating the extension of high-quality rehabilitation medical resources to underserved areas. It promoteed the integration of standardized and specialized rehabilitation therapies by unifying protocols for homogeneous management while encouraging grassroots institutions to develop distinctive specialties. By emphasizing the synergy between clinical care and rehabilitation, multidisciplinary rehabilitation teams were established to operate joint clinics and wards. Additionally, home-based rehabilitation services were advanced through remote collaboration via " virtual wards" . As of 2024, this rehabilitation system had been implemented across 25 county medical community in Ningbo, significantly enhancing regional rehabilitation service capacity and expanding the scope of primary-level rehabilitation care. It had achieved continuity and intelligence in rehabilitation services, meeting diverse patient needs with notable success. This practice provided valuable insights for other regions seeking to strengthen their rehabilitation service systems.

Objective:To analyze the serological and molecular characteristics of rare A el and B el subtypes in the ABO blood group system, and to explore their genotype-phenotype correlation and the potential clinical significance. Methods:From January 1st, 2021, to January 1st, 2025, 289, 815 samples subjected to ABO blood grouping in Henan Provincial People′s Hospital were selected. Samples demonstrating discrepancies between forward and reverse typing, or consistent typing but with abnormal agglutination degree were included. Those affected by underlying diseases, transplantation, age-related and other interferences were excluded. A total of 169 suspected ABO subgroup samples were identified. Sanger sequencing of exons 1-7 and relevant regulatory regions of the ABO gene was performed. Protein structure modeling and mutation effect analysis for two'el′ subtype glycosyltransferases (GTs) were conducted using SWISS-MODEL and PyMOL.Results:A total of 12 Ael, 6 B el, and 2 AB el subtypes were identified. Serological analysis revealed that all 18 A el/B el samples exhibited O phenotype in forward typing. Among them, A el subtypes showed weaker agglutination in reverse typing with A 1c than with Bc (>2+), while the opposite pattern was observed in B el subtypes. The two AB el samples were typed as A in forward typing, with agglutination ranging from 0-1+with Bc in reverse typing. Genetic analysis indicated that AEL.02 (c.646T>A, p.Phe216Ile) was the predominant allele in A el samples accounting for 7 cases. Also, we found an AEL.02-like variant (lacking c.681G>A), AEL.10 (c.963insC), and carrying a compound variant of c.322C>T (p.Gln108Ter) and c.296C>T (p.Thr99Ile). Among B el samples, BEL.03 (c.502C>T, p.Arg168Trp) accounted for 4 cases, one of which lacked the c.297A>G mutation, and novel mutations such as c.145_146dupCG were detected. Structural simulation demonstrated that AEL.02 and BEL.03 disrupted the hydrogen-bonding network within the active centers of GTA and GTB, respectively, and these mutations probably significantly impaired the structural stability of the corresponding GTs. Additionally, the c.296C>T mutation also markedly affected GTA structural stability. Conclusion:A el/B el subtypes are prone to mis-identify routine blood types. Their molecular mechanisms involved a variety of functional variantions, and integrating molecular detection is crucial for achieving accurate sub-typing and transfusion safety.

Objective:To investigate the clinical significance of prenatal screening and genetic analysis in the diagnosis of fetal aberrant right subclavian artery(ARSA).Methods:The ultrasonographic features of ARSA fetu-ses detected by prenatal ultrasound at the University of Hong Kong-Shenzhen Hospital from October 2017 to March 2022 were retrospectively analyzed.The fetuses were divided into isolated ARSA group and complicated ARSA group.Their genetic analysis results and pregnancy outcome were analyzed.Results:Among 30,260 preg-nant women,185 fetuses were diagnosed with ARSA by prenatal ultrasound screening,with an incidence of 0.6％;5 fetuses(2.6％)were diagnosed by ultrasound in the first trimester,and the remaining were diagnosed by fetal grade Ⅲ structural ultrasound examination at 20～24 weeks' gestation.Among them,158 fetuses(85.4％)had isolated ARSA,and 27(14.6％)had complicated ARSA.Among fetuses with ARSA and other structural abnormal-ities,cardiovascular system accounted for the highest proportion(44.4％),followed by nervous system(22.2％)and urinary system(22.2％).Through genetic analysis,8.3％(4/48)fetuses with isolated ARSA and 40.0％(4/10)fetuses with complicated ARSA were found to have chromosomal numerical or structural abnormalities,with statis-tically significant difference between the two groups(P=0.024).Genetic analysis was completed in 48 isolated ARSA,and the positive rate of pathogenic copy number variants(CNV)was 4.2％(2/48),which was not signifi-cantly different from the pathogenic CNV incidence rate of 0.4％(1/239)in elderly pregnant cases during the same period(P=0.074).The Down syndrome positive likelihood ratio(LR+)for isolated ARSA was 2.5 and the Down syndrome LR+for complicated ARSA was 49.6.Conclusions:Complicated ARSA is often associated with cardiovascular abnormalities and is more likely to develop Down syndrome than isolated ARSA.Although the inci-dence of pCNV in isolated ARSA is slightly higher than the natural incidence,the correlation between pCNV and i-solated ARSA has not been clearly determined by the current sample size.

Objective:To develop and validate a predictive model for delayed emergence in patients undergoing thoracoscopic radical lung cancer surgery with general anesthesia.Methods:A total of 1 468 patients admitted to the anesthesia recovery room after thoracoscopic radical lung cancer surgery at the First Affiliated Hospital of Zhejiang University School of Medicine from August 2020 to August 2021 were selected via convenience sampling. Patients who underwent surgery between August 2020 and June 2021 ( n=1 213) were assigned to the modeling group, while those from July to August 2021 ( n=255) were used as the validation group. Logistic regression analysis was used to identify risk factors for delayed emergence and to establish a predictive model. The performance of the model was evaluated using the area under the receiver operating characteristic curve ( AUC) and the Hosmer-Lemeshow goodness-of-fit test. Results:Among the modeling group, 200 patients experienced delayed emergence, with an incidence of 16.49% (200/1 213). Logistic regression analysis revealed that the use of reversal agents, use of neostigmine, albumin level, presence of shivering, pain score≥4 points, extubation time, partial pressure of CO 2, partial pressure of oxygen, serum potassium level, and intraoperative fentanyl dosage were significant influencing factors ( P<0.05). The predictive model demonstrated good performance with an AUC of 0.864 [95% CI (0.828, 0.899) ], a Hosmer-Lemeshow test χ 2=5.299 ( P=0.725), cut-off value of 0.442, sensitivity of 0.794, and specificity of 0.769. In the validation group, delayed emergence occurred in 44 cases (17.25%). The model showed good validation performance with an AUC of 0.852 [95% CI (0.826, 0.878) ], Hosmer-Lemeshow χ 2=5.912 ( P=0.336), cut-off value of 0.754, sensitivity of 0.674, and specificity of 0.877. Conclusions:The predictive model constructed in this study demonstrates strong performance and can assist clinicians in the early identification of patients at risk of delayed emergence following thoracoscopic radical lung cancer surgery under general anesthesia.

Tuberculosis is a zoonotic disease posing a substantial public health threat.Immunological diagnosis and vaccine im-munization are both necessary to control tuberculosis prevalence.However,the identical antigenic components in diagnostic reagents and vaccines hinder the use of animal vaccines and limit the specificity of clinical diagnosis in humans.Differentiating infected from vaccinated animals can overcome these problems.This article reviews the progress in differential diagnosis research from three as-pects:the diagnostic effects of antigens,methods for discovering new antigens,and screening of new host immune markers,to provide a theoretical basis for future research.

Objective To observe the clinical efficacy of Ruanjian Sanjie Pills in the treatment of patients with hepatitis B-related cirrhosis in compensatory stage differentiated as blood stasis blocking collaterals syndrome.Methods A total of 80 cases of patients with hepatitis B-related cirrhosis in compensatory stage admitted to Bao'an Hospital of Chinese Medicine Affiliated to Guangzhou University of Chinese Medicine from January 2023 to April 2024 were randomly divided into the trial group and the control group,40 cases in each group.The control group was treated with oral administration of Entecavir for hepatitis B virus(HBV),and the trial group was treated with Ruanjian Sanjie Pills on the basis of treatment for the control group,the course of treatment covering one year.Before and after treatment,the two groups were observed in the changes of routine blood test indicators of white blood cell count(WBC)and platelet count(PLT),liver function indicators[albumin(ALB),total bilirubin(TBIL),alanine transaminase(ALT)and aspartate transaminase(AST)],prothrombin time(PT),liver stiffness measurement(LSM),and traditional Chinese medicine(TCM)syndrome scores.After treatment,the clinical efficacy and safety were evaluated.Results(1)There were three cases in the control group and four cases in the trial group fell off,and eventually 37 cases in the control group and 36 cases in the trial group were enrolled in the efficacy statistics.(2)After one year of treatment,the total effective rate of the trial group was 91.67%(33/36)and that of the control group was 67.57%(25/37),and the intergroup comparison(tested by chi-square test)showed that the therapeutic efficacy of the trial group was significantly superior to that of the control group(P<0.05).(3)After treatment,the routine blood test indicators of WBC and PLT in the trial group were increased compared with those before treatment(P<0.05),while the WBC and PLT in the control group did not change significantly(P>0.05).The post-treatment WBC and PLT in the trial group were significantly higher than those of the control group(P<0.05).(4)After treatment,the ALB of patients in the two groups was increased compared with that before treatment(P<0.05),and the PT value of patients in the two groups and the ALT of the trial group were decreased compared with those before treatment(P<0.05),but TBIL and AST of the two groups and ALT of the control group did not differ from those before treatment(P>0.05).The comparison between the two groups showed that the decrease of PT value in the trial group was significantly superior to that of the control group(P>0.05),but no statistically significant differences of ALT,AST,TBIL and ALB were shown between the two groups(P>0.05).(5)After treatment,the LSM of patients in the two groups was decreased compared with that before treatment(P<0.05),and the decrease in the trial group was significantly superior to that in the control group(P<0.05).(6)After treatment,the TCM syndrome scores of the two groups of patients were decreased compared with those before treatment(P<0.05),and the decrease in the trial group was significantly superior to that in the control group(P<0.05).(7)There were no significant adverse reactions or adverse events occurring in the two groups during the treatment.Conclusion Ruanjian Sanjie Pills can improve the clinical symptoms of patients with hepatitis B-related cirrhosis in the compensatory stage,improve the coagulation function,reduce the hardness of the liver,and slow down the process of cirrhosis,with satisfactory efficacy and good safety.

Objective To explore the effectiveness of multimodal comprehensive diabetes management teaching in the standardized training of endocrinology residents.Methods Fifty-nine resident physicians rotating through the endocrinology department from March to October 2024 were selected.They underwent a multimodal comprehensive diabetes management teaching model that integrated standardized theoretical instruction,case dis-cussions,teaching ward rounds,practical operations,and interdisciplinary pharmaceutical education.The effec-tiveness of this teaching model was evaluated through multiple dimensions using a comprehensive diabetes man-agement evaluation form,Mini-Clinical Evaluation Exercise(Mini-CEX)scale,and satisfaction surveys.Results After two months of multimodal standardized training,the results showed:1)The resident physicians demonstra-ted significant improvements in all aspects of comprehensive diabetes management(P＜0.05).2)The Mini-CEX scores of the resident physicians generally reached excellent levels(P＜0.05).3)Both the resident physicians and teaching faculty showed significantly higher satisfaction with the comprehensive diabetes management program after the training(P＜0.05).Conclusions Multimodal comprehensive diabetes management teaching is effective in enhancing the standardized diagnosis and treatment abilities of resident physicians in the endocrinology depart-ment regarding diabetes.
