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 distribution of HPA, HLA alleles and haplotypes among apheresis platelet donors in Changsha, China, and to establish an apheresis platelet donor database. Methods: High-resolution genotyping of HLA-A and -B was performed using PCR sequence based typing (SBT) and next generation sequencing (NGS). HPA genotyping was conducted using quantitative PCR (Q-PCR). The allele frequency, haplotype frequency and linkage disequilibrium parameters were calculated using the direct counting method, the maximum likelihood method and Arlequin software (V 3.1). Results: A total of 41 HLA-A alleles and 82 HLA-B alleles were detected, and 457 HLA-A-B haplotypes were found, of which 25 showed strong linkage disequilibrium (RLD>0.50). The HPA-3 and HPA-15 had the highest HPA polymorphism and antigen mismatch rate in apheresis platelet donor database in Changsha, and the dual antigen mismatch rate was 0.3704 and 0.3743, respectively. Conclusion: The polymorphism of apheresis platelet donor database in Changsha is complex and has strong regional characteristics. Establishing a high-resolution donor database will strongly support the provision of genetically matched platelets for clinical use, facilitating precise platelet transfusion therapy.

ObjectiveTo evaluate the impact of narrative medicine education on the narrative ability of resident physicians undergoing standardized residency training， and to explore its application value in clinical practice. MethodsA total of 23 obstetricians and gynecologists who participated in residency training at the Fourth Hospital of Hebei Medical University from October 2021 to June 2024 were randomly selected to receive a 3-month residency training program integrated with narrative medicine education， including narrative theory learning， text reading， reflective writing， and scenario-based case analysis. A questionnaire survey was conducted to analyze the personal situation of resident physicians， their narrative ability before and after receiving narrative medicine education， and their satisfaction with teaching. ResultsThe results of the questionnaire survey showed that resident physicians who had received narrative medicine education scored higher on the narrative ability assessment scale than before training， including improved narrative abilities in the dimensions of life and health narrative awareness， professional narrative thinking， professional development narrative behavior， peer communication narrative behavior， and doctor-patient interaction narrative behavior （P<0.05）. However， there were no statistically significant differences in the dimensions of life and health narrative behavior and family connection narrative behavior （P>0.05）. Meanwhile， resident physicians’ interest in active learning， clinical thinking ability， doctor-patient communication ability， and satisfaction with teaching methods have also been improved （P<0.05）. ConclusionNarrative medicine education can effectively enhance the narrative ability of resident physicians and make up for the current deficiencies in humanistic literacy and ethical education in current medical education. It is of great significance for improving doctor-patient relationships and the quality of medical services. Therefore， it is recommended to integrate narrative medicine education into the regular training curriculum for resident physicians.

Endogenous estrogen is currently considered a major risk factor for postmenopausal breast cancer. Under the catalysis of various enzymes,estrogen interacts through multiple metabolic pathways to produce various metabolites. The imbalance of estrogen and its metabolites in the body can induce physiological changes that may play a dual role in the development of breast cancer. However,due to the relatively low estrogen levels in postmenopausal women and the limitations of existing measurement methods in terms of specificity,accuracy,and reproducibility,the precise role of different estrogen metabolic pathways and their metabolites in the etiology of postmenopausal breast cancer remains unclear. Therefore,a deeper understanding of the estrogen metabolism pathways and their metabolites in the occurrence and progression of postmenopausal breast cancer may provide new insights for its prevention and treatment. Here,the authors review recent research progress on estrogen metabolism and postmenopausal breast cancer.

Objective:To explore the relationship between the clinical outcome of emotional symptoms and cognitive performance and related cerebral oxygenated hemoglobin in adolescents with depression.Methods:Through subject recruitment, 46 adolescent patients with depression (patient group) from the First Hospital of Shanxi Medical University were selected as the subjects for this study from December 2020 to December 2021, including 8 males and 38 females, aged 12-18 (15.7±2.3) years old. All patients received sertraline treatment for 8 weeks and were further followed into responders ( n=24) and non-responders ( n=22) according to the outcome of emotional symptoms. In the meantime, 51 healthy controls (control group) were enrolled, including 7 males and 44 females, aged 12-18 (16.1±1.5) years old. The repeatable battery for the assessment of neuropsychological status (RBANS) was conducted to measure the multi-dimensional neurocognitive performance, and the functional near-infrared spectroscopy (fNIRS) was used to assess changes in the concentration of oxyhemoglobin (HBO) during the verbal fluency test. The differences were compared in multi-dimensional cognitive performance and cerebral HBO level between each patient group and control group and between responders and non-responders. The changes were analyzed in cognitive performance and cerebral HBO level after intervention in responders and non-responders. Results:At baseline, compared to the control group, the patient group performed decreased scores of RBANS, immediate memory, speech function, attention, and delayed memory (88.0 (82.8, 100.0) M ( Q1, Q3) vs. 100.0 (90.0, 110.0) scores; 78.0 (73.0, 87.8) vs.85.0 (78.0, 94.0) scores; (84.4±16.1) vs. (95.7±15.7) scores; 106.0 (99.5, 115.0) vs.118.0 (109.0, 128.0) scores; 94.0 (84.5, 99.0) vs.97.0 (91.0, 101.0) scores), and lower HBO levels in 7 channels (all P<0.05). Compared to responders, non-responders showed more severe impairment of visual-spatial and attention performance (103.9±11.0 vs. 94.4±16.7 scores; 112.5±12.1 vs. 98.0±21.2 scores) ( t=2.30 or 2.87; all P<0.05). After treatment, the scores of RBANS and immediate memory improved significantly in responders (98.8±11.2 vs. 93.0±9.7 scores; 95.2±13.8 vs.83.0±14.6 scores) ( t=-3.00 or-4.97; both P<0.05), but the scores of attention and the HBO level of two channels in the prefrontal cortex were still significantly lower than those of the control group (Z=2.27, 3.02 or 3.04; all P<0.05). Besides, there were no significant differences in the scores of immediate memory and the HBO levels of 3 channels in the temporal lobe between the no-responders and the control group (all P>0.05). Conclusion:Immediate memory injure, attention injure and HBO levels of frontal-temporal lobes may be independent of emotional symptoms among adolescents with depression.

Objective:To explore the differences in therapeutic effect and prognosis of different molecular subtypes of breast invasive lobular carcinoma treated with nab-paclitaxel, so as to provide a basis for the selection of clinical drugs for breast cancer.Methods:The data of 180 patients with advanced invasive lobular carcinoma of the breast who were treated in Handan Central Hospital and the Fourth Hospital of Hebei Medical University from January 2017 to January 2020 were retrospectively analyzed, including 34 cases of Luminal A type, 92 cases of Luminal B type, 21 cases of human epidermal growth factor receptor 2 (HER2) overexpression type, and 33 cases of triple-negative type. The patients were treated with nab-paclitaxel, and the clinical curative effect was evaluated according to the solid tumor response evaluation criteria version 1.1 after 1 year of treatment, and the objective response rate (ORR) (calculated as complete remission + partial remission) and clinical benefit rate (CBR) (calculated as complete remission + partial remission + stable disease) were calculated; the occurrence of adverse reactions during the treatment was recorded. The Kaplan-Meier method was used to draw the progression-free survival (PFS) and overall survival (OS) curves for each subtype of patients, and the log-rank method was used to test them.Results:The differences in ORR and CBR among patients with the four subtypes of Luminal A, Luminal B, HER2 overexpression, and triple-negative were statistically significant (all P < 0.001), with the triple-negative type having the lowest ORR and CBR [21.2% (7/33) and 63.6% (21/33)] and the Luminal A type having the highest ORR and CBR [70.6% (24/34) and 100.0% (34/34)]. The ORR and CBR of Luminal B type were 45.7% (42/92) and 90.2% (83/92), and the HER2 overexpression type was 38.1% (8/21) and 90.5% (19/21). The differences in the incidence of myelosuppression, numbness of limbs, joint and muscle pain among the four subtypes were statistically significant (all P < 0.05), with the triple-negative type having the highest incidence of all of the above adverse reactions. The PFS and OS of triple-negative subtype were worse than those of Luminal A, Luminal B and HER2 overexpression subtypes, and the differences were statistically significant (all P < 0.05). Conclusions:The clinical response and prognosis of patients with different molecular subtypes of invasive lobular carcinoma is significantly different after nab-paclitaxel intervention, among which the prognosis of patients with triple-negative type is the worst, and the clinical medication can be guided according to the pathological test results.

【Objective】 To investigate the gene frequency and polymorphism of RBC blood group systems in RhD negtive population in Hunan, so as to lay a foundation for clinical blood transfusion and construction of multiple rare blood group database. 【Methods】 Blood samples were taken from 300 RhD negative blood donors, confirmed by serological method, from June 2019 to June 2020,. RHD genotyping was performed by SSP-PCR. For blood donors with typing results as RhD negative plus RHD gene deletion, antigens genotyping of MNS, Duffy, Kell, Domrock, Diego, Kidd, Sciawnna, Colton, Lutheran and Yt RBC blood group systems were performed by SSP-PCR and analyzed by the chi square test of SPSS 20 statistical software. 【Results】 RHD gene deletions accounted for 58.67% (176 / 300) of serological D negative blood donors. The gene frequencies were as follows: MNS: GYPB^*S=0.045 5(8/176), GYPB^*s=0.954 5(168/176), GYP^*Dane=0.039 8(7/176); Duffy: FY^*A =0.965 6(170/176), FY^*B=0.034 1(6/176); Dombrock: DO^*A=0.082 4(14.5/176), DO^*B=0.917 6(161.5/176); Diego: DI^*A=0.025 6(4.5/176), DI^*B =0.974 4(171.5/176); Kidd: JK^*A=0.485 8(85.5/176), JK^*B=0.514 2(90.5/176); Kell: KP^*A=0.005 7(1/176), KP^*B=0.994 3(175/176); Lutheran: LU^*A=0.005 7(1/176), LU^*B=0.994 3(175/176); Yt: YT^*A=0.002 8(0.5/176), YT^*B=0.997 2(175.5/176). The genotypes of Kell(K+ /k+ ), Scianna and Colton blood groups were KEL^*02 /KEL^*02, SC^*01 /SC^*01 and CO^*A /CO^*B, respectively. The expected frequencies of the combination of type O, RhD negative and other blood group systems were between 1/100 000 to 1/10 000. 【Conclusion】 Among RhD negative blood donors in Hunan, the gene profiles of MNS, Duffy, Domrock, Diego, Kidd, Kell and Lutheran blood group system were polymorphic, and Kell (K+ /k+ ), Colton and Scianna were homozygous. The data of other RBC blood group systems from RhD negative blood donors is of great significance to establish local database of rare blood groups.
