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.

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.

OBJECTIVE: Although the pathogenesis of depression remains unclear, C-reactive protein (CRP) levels are commonly elevated in depressed patients. Thus, CRP single-nucleotide polymorphisms (SNPs) that influence CRP levels may be associated with depression. In the present study, we explored whether CRP SNPs are related to depressive symptoms and antidepressants efficacy in Han Chinese patients.METHODS: We analyzed data from 440 patients with first-episode depression. We obtained genome CRP SNPs, scores of the 17-item Hamilton Rating Scale for Depression 17 (HAMD17) and its four-factor at baseline and after 6 weeks. Quantitative trait analysis was performed using UNPHASED software and curative effects were analyzed using SPSS software.RESULTS: Male patients with SNP rs1800947G exhibited lower insomnia scores and rs2794521CC exhibited lower scores of anxiety/ physical symptoms, total HAMD17 score. Female patients with rs2794521TT exhibited higher scores of insomnia and lower antidepressants efficacy.CONCLUSION: CRP SNPs rs1800947 and rs2794521 may be associated with depressive symptoms in patients with depression in a sex-specific fashion. Furthermore, rs2794521 may be a predictor of the efficacy of antidepressants in female patients.

Compared with mitral valve parameters before PCI and at one week after PCI ,AP ,AL-PM ,AC ,CD ,AA3D ,and TV in improvement group were discreased at three months after PCI( P < 0 .05) ,AH was increased ( P < 0 .05) . Compared with mitral valve parameters before PCI ,mitral valve structure and function parameters after PCI were not improved ,compared with those in no improvement group ,AP ,AL-PM ,AC ,CD ,and AA3D in improvement group were smaller( P < 0 .05) . ③ By analysis of ROC curves AP ,AL-PM ,AC ,and CD for diagnosing mitral regurgitation had good test effectiveness . Conclusions In patients with acute myocardial infarction and moderate mitral regurgitation ,the mitral annular is not only presented as the size enlargement but also the flattening of its geometric shape and the decrease of its dynamic ,while structure and function parameters of the mitral valve before PCI can predict improvement of mitral regurgitation and provide a reference for the development of clinical programs .

Objective To investigate the status of depression with anxiety symptoms, and analyze the influencing factors of anxiety symptoms from demographic data and social psychological factors. Methods Hamilton depression rat?ing scale (HAMD), Hamilton anxiety rating scale (HAMA), Eysenck personality questionnaire (EPQ), life event scale (LES), trait coping style questionnaire (TCSQ) and social support scale (SSS) were used to evaluate 729 patients with de?pression. According to HAMA scores, patients were divided into non anxiety symptoms group (HAMA<7) and anxiety symptoms group (HAMA>14). Social psychological factors were compared between two groups, and the influencing fac?tors of anxiety symptoms were analyzed. Results The incidence of anxiety symptoms in depression was 58.85% (429/729), and 119 cases (16.32%) were certainly without anxiety symptoms. Compared with the group without anxiety symp?toms, the anxiety symptoms group had higher scores on neuroticism, psychoticism, negative life events and negative cop?ing style (P<0.001), but lower scores on introversion and extroversion (P=0.010). Degree of depression (OR=9.255, 95%CI:4.726~18.127), neuroticism (OR=1.595, 95%CI:1.197~2.125), negative life events (OR=1.009, 95%CI:1.001~1.017) and negative coping style (OR=1.046, 95%CI:1.013~1.080) were the risk factors of anxiety symptoms (P<0.05). Conclu?sion The incidence of anxiety symptoms in patients with depression is high. Patients with higher degree of depression and typical neurotic personality experiencing more negative life events and those with tendency to adopt negative coping style are more susceptible to anxiety symptoms.
