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.

AIM: To explore the application effect of eyelid margin incision combined with floating bridge technique in the treatment of ptosis patients, and to analyze its effects on the margin reflex distance 1(MRD1)and the aesthetic effect of the eyes. METHODS:Prospective study. This study enrolled patients with blepharoptosis treated at the Department of Ophthalmology of the hospital between January 2023 and July 2025, who were assigned to either an observation group or a control group. The patients in the control group received levator aponeurosis shortening surgery through conventional double-eyelid incision, while the patients in the observation group underwent levator aponeurosis shortening surgery using the eyelid margin incision combined with floating bridge technique. Subsequently, the surgical-related indicators,the correction effect of ptosis, the aesthetic effect, the ocular function indicators, the postoperative complication occurrence rate, and recurrence rate were compared and analyzed between two groups.RESULTS:A total of 100 patients(100 eyes)with blepharoptosis were enrolled in this study, with 50 patients(50 eyes)in the observation group and 50 patients(50 eyes)in the control group. The observation group had a mean age of 27.33±5.32 y, including 20 males and 30 females. The control group had a mean age of 27.64±4.66 y, including 24 males and 26 females. Compared with the control group, the operative time of the observation group was longer, the postoperative swelling resolution time and natural recovery time were shorter,and the correction rate was higher(P<0.05). Three months after the surgery, the VSS score and POSAS score of the observation group were lower than those of the control group, while the scores for eyelid curvature, symmetry of eyelid height, and the PFH, MRD1, palpebral fissure size, and upper eyelid levator muscle strength were all higher than those of the control group(all P<0.05). However, there was no significant difference in postoperative complication occurrence rate and recurrence rate between two groups(all P>0.05).CONCLUSION:The combined use of eyelid margin incision and floating bridge technique for treating ptosis results in slightly longer operation time, but it can shorten the postoperative recovery period, effectively ameliorate the MRD1 and ocular function of patients, and enhance the correction effect and aesthetic quality of the eyes. In addition, it has a low incidence of complications and guaranteed safety.

Objective We reviewed and analyzed the epidemiological data of 83 imported dengue fever cases reported in Fengtai District, Beijing, from 2007 to 2025, to delineate their epidemiological characteristics and guide the dengue fever prevention and control strategy in the future. Methods Data on dengue fever cases in Fengtai District from 2007 to 2025 were collected to identify the epidemic factors and characteristics using descriptive epidemiological method. Results All 83 dengue fever cases reported in this region over the past two decades have been imported from abroad or other domestic areas, with Southeast Asian countries being identified as the primary source of imported infections, accounting for 42 cases (50.60%), followed by 15 cases (18.07%) from Chinese provinces other than Beijing. The remaining import sources included 13 cases from South Asia,8 from African countries, and each from Oceania, South America, and Europe. Disease onset was found concentrated between May and November. The sex ratio (male-to-female) is 1.59:1. The age of onset ranged from 14 to 61 years old, with a median age of 36. The largest proportion of cases was observed among cadres and office workers (31 cases, 37.35%), followed by businessmen (13 cases, 15.67%), and householders or the unemployed (10 cases,12.05%). Travel visit was identified as the primary reason for their exposure history. Conclusions All dengue fever cases reported in Fengtai from 2007 to 2025 were imported, with an increasing trend of imported cases in Beijing originating from other Chinese provinces. It is essential to strengthen health education for foreign travelers and returning residents, enhance clinical diagnosis and treatment training for medical personnel, eliminate mosquito breeding sites, and reduce mosquito density through active patriotic health campaigns.

Objective:To analyze the drug resistance and virulence characteristics of KPC-2-producing carbapenem-resistant Klebsiella pneumoniae(CRKP). Methods:A total of 26 non-repeating CRKP strains clinically isolated from a Class Ⅲ hospital in Kunming from August 2021 to March 2022 were collected. Mass spectrometry and the VITEK 2 Compact system were used to identify the bacteria and perform drug susceptibility tests. PCR was used to amplify the drug resistance and virulence genes carried by the strains. These CRKP strains were divided into a hypervirulent CRKP(CR-hvKP) group and a CR-non-hvKP group according to the characteristic virulence genes of hypervirulent Klebsiella pneumoniae. The virulence phenotypes of CRKP were investigated by wire drawing test, serum resistance test and siderophore qualitative and quantitative tests. The whole genomes of CRKP-67 (a CR-hvKP strain) and CRKP-94 (a CR-non-hvKP strain) were sequenced by the Illumina high-throughput sequencing platform, to further analyze the drug resistance genes, virulence genes, and virulence plasmidds carried by the strains. Results:The drug sensitivity results indicated that all 26 strains were resistant to carbapenem, cephalosporins, fluoroquinolones and β-lactam/β-lactam inhibitor complexes. The resistance rates to amicacin, cotrimoxazole and gentamicin were 61.54%(6/26), 57.69%(15/26) and 73.08%(9/26), respectively. Regarding the drug resistance gene amplification results, the carrying rates of blaKPC-2, blaNDM-1, blaOXA-48, blaVIM, blaIMP, blaSME, blaSHV, blaCTX-M and blaTEM were 100.00%(26/26), 0, 0, 0, 0, 100.00%(26/26), 100.00%(26/26), 15.38% (4/26) and 73.08%(19/26), respectively. In the 26 strains, the carrying rates of toxic genes entB, entC, ureA, uge, wabG, ycf, irp1, irp2, mrkD, fimH and ybtS were 100.00%(26/26), while the carrying rates of virulence genes kfuB, iroN, aero, magA and alls were 0. The positive rate of string test was 66.7%(6/9) in the CR-hvKP group and 0 in the CR-non-hvKP group. The serum killing test showed a high sensitivity rate of 77.78%(7/9), a low sensitivity rate of 11.11%(1/9), and a serum resistance rate of 11.11%(1/9) in the CR-hvKP group. In the CR-non-hvKP group, the high sensitivity rate was 29.41%(5/17); the low sensitivity rate was 17.65%(3/17), and the serum resistance rate was 52.94%(9/17). There was no statistical significance between the two groups( P>0.05). The qualitative results of siderophore showed that all strains produced yellow chelating circles with slightly different color depth and size. The quantitative results of siderophore experiment showed that the average siderophore production level of CR-hvKP group was 40.74%, and that of CR-non-hvKP group was 28.21%. The level was higher in the CR-hvKP group than in the CR-non-hvKP group, and the difference was statistically significant( P<0.05). Whole-genome sequencing results showed that CRKP-67 was ST11 type and contained 3 plasmids. Among them, plasmid pCRKP-67-A carried a series of virulence genes, including iucABCD, iutA, rmpA, rmpA2, iroB and peg344, which were highly virulent characteristic genes. Plasmid pCRKP-67-B carried blaKPC-2, blaCTX-M, blaSHV, blaTEM and other drug-resistant genes. Plasmid pCRKP-67-C carried sul2, tetR, tetA and other drug-resistant genes. The CRKP-94 was of ST340 type and contained a drug-resistant plasmid carrying blaKPC-2, blaCTX-M, blaSHV, blaTEM and other drug-resistant genes. Conclusions:CRKP strains are highly resistant, and are only sensitive to a few antibiotics, and carry a variety of drug resistance genes. The main resistance mechanism to carbapenem antibiotics is the presence of the blaKPC-2 gene, which is located on the plasmids, which results in the spread of carbapenem resistance. The types and quantity of virulence genes carried by the CR-hvKP strain are more and greater respectively than those carried by the CR-non-hvKP strain. The co-existence of drug-resistant and virulence plasmids in CR-hvKP strains may lead to the co-transmission of high drug resistance and hypervirulence, which should be highly valued by relevant departments.

Objective:To explore the clinical characteristics, treatment and prognosis of hard metal lung disease (HMLD), and to provide a theoretical reference basis for the prevention, control and intervention of HMLD in China.Methods:In April 2024, literatures related to HMLD and giant cell interstitial pneumonia (GIP) published before March 31, 2024 were retrieved in China National Knowledge Infrastructure (CNKI), Wanfang, VIP database, Embase and PubMed. The search terms in Chinese and English included hard metal lung disease, cobalt, tungsten carbide, giant cell interstitial pneumonia, hard metal, etc. Literature was screened and data were extracted. A systematic review was conducted to analyze the clinical characteristics, imaging, pulmonary function, pathological features, treatment and prognosis of HMLD.Results:A total of 55 literatures were included, including 1 cohort study, 4 cross-sectional studies, 4 case series reports and 46 case reports, involving a total of 227 patients with HMLD and GIP. There were 174 male cases, 51 female cases, and 2 cases whose gender was not mentioned. The age was (43.9±13.4) years old, and the dust exposure time was 7 (4, 13) years. The chest images of the patients showed ground glass shadow, micro-nodule shadow, grid shadow, honeycomb shadow, consolidation shadow, etc. Pulmonary function test showed restrictive ventilation dysfunction with gas exchange disorder. The pathological manifestations of lung tissue were typical GIP, but there were also hypersensitivity pneumonitis, common interstitial pneumonia, diffuse alveolar damage, non-specific interstitial pneumonia, and even honeycomb lung. Clinical diagnosis and treatment evaluation were performed by combining the occupational exposure history of hard metal dust or cobalt-containing dust, clinical manifestations, imaging, lung function and histopathology. Treatment involved cessation of exposure, with glucocorticoids alleviating symptoms and improving imaging and pulmonary function.Conclusion:HMLD can be caused by hard metal dust exposure. The clinical symptoms of HMLD are not specific, and the pathology shows typical GIP or other pulmonary interstitial changes. The treatment involves cessation of exposure and administration of glucocorticoids, and the overall prognosis is good.

Objective To understand the current status of illness benefit perception among caregivers of type 2 diabetes patients,analyze its relationship with coping strategies and social support,and explore its influencing factors.Methods Using a convenience sampling method,240 caregivers of type 2 diabetes patients hospitalized in the endocrinology department of a tertiary hospital in Kunming from October 2023 to October 2024 were selected.Questionnaires including general information survey,Benefit Finding Scale,Simplified Coping Strategy Scale,and Social Support Rating Scale were used to investigate the caregivers.Results The caregivers'benefit finding score was(66.82±16.73),coping strategy score was(36.01±9.64),and social support score was(42.00±8.11).Pearson correlation analysis showed positive correlations between coping styles,social support,and illness benefit perception(r=0.445,r=0.493,P<0.01);multiple linear regression analysis indicated that family residence,education level,duration of caregiving,and understanding of the patient's disease were key factors influencing illness benefit perception(P<0.01).Conclusion Caregivers of type 2 diabetes patients have a moderate level of illness benefit perception,with positive correlations between coping strategies,social support,and illness benefit perception.The disease benefit perception of caregivers is also influenced by family residence,education level,caregiving duration,and disease knowledge.

Objective To compare the clinical and functional differences between transoral and submandibular approach in mandibu-lar segmental resection and reconstruction with free fibula flaps(FFFs).Methods Patients who underwent mandibular segmental re-section and FFFs reconstruction in the Department of Oral and Maxillofacial Surgery of the Affiliated Stomatological Hospital of Nanjing Medical University from January 2015 to March 2023 were retrospectively analyzed.All cases were divided into transoral approach and submandibular approach groups.Clinical characteristics of the patients were recorded including age,gender,follow-up time,pathologi-cal diagnosis,body mass index(BMI),American Society of Anesthesiologists(ASA)classification,James Brown classification of mandibular defect and number of fibular segments.The perioperative indexes,such as average operation time,average bleeding vol-ume,average blood transfusion volume,average drainage volume,average hospitalization time and postoperative complications such as malocclusion,fistula,infection,flap failure,and restriction of mouth opening were compared between the two groups.The University of Washington Quality of Life Questionnaire was used to investigate the appearance,function of swallow and speech more than 6-month postoperatively.Results The average intraoperative bleeding and postoperative drainage were significantly lower in the transoral ap-proach group than in the submandibular approach group(P=0.013 9,P=0.001 9).The appearance score was significantly higher in the transoral approach group than in the submandibular approach group(83.52±12.37)vs.(67.19±13.64)(P＜0.000 1).The differ-ences between the two groups in other variables were not statistically significant.Conclusion Cases of transoral approach had signifi-cantly better aesthetic outcomes compared with those of submandibular approach.

Objective To investigate the clinical characteristics of women with abnormal uterine bleeding(AUB)in sub-plateau regions and analyze the factors affecting their treatment methods.Methods AUB patients who were hospitalized from Jan 1,2018 to Dec 31,2022,in a sub-plateau region(Yongping County People's Hospital of Yunnan Province)with an average altitude of 1 620 meters were selected.The general clinical characteristics of the patients were summarized,and patients were classified into two categories(with or without uterine structural lesion)and nine subtypes(PALM-COEIN)according to the FIGO recommended etiological classification guidelines.Then the patients were divided into groups based on the presence or absence of uterine structural lesions,ethnic group(Han and minority),conservative drug treatment and surgical treatment groups,blood transfusion and non-blood transfusion groups.Binary Logistic regression analysis was used to identify factors affecting treatment methods.Results A total of 481 AUB patients enrolled,and the delayed consultation rate was as high as 80.46%,and the proportion of overweight and obese patients was 49.90%,which was higher than the average level among Chinese women.The main cause was AUB-O(AUB-ovulatory dysfunction),accounting for 78.59%of cases,the proportion of patients with delayed medical treatment was higher than those without delayed medical treatment(82.17%vs.74.47%).Patients who received blood transfusion were significantly younger,had lower hemoglobin(HGB)levels,fewer pregnancies,and lower BMI compared to those in the non-blood transfusion group(P<0.05).Univariate analysis showed that the surgical treatment group had older age,longer onset time,higher HGB levels,more pregnancies and deliveries,higher BMI,a higher proportion of Han ethnicity patients,lower rates of non-blood transfusion,higher rates of hypertension,and more uterine structural lesions compared to the conservative drug treatment group.Multivariate regression analysis revealed that blood transfusion treatment reduced the probability of surgical treatment.Age and uterine structural lesions were risk factors for requiring surgical treatment,for each additional year of age,the risk of undergoing surgical treatment increased by 10%.The risk of requiring surgical treatment for patients with uterine structural lesions was 2.987 times higher than for those without.Conclusion AUB patients in this sub-plateau regions have a high rate of delayed consultation and a high proportion of overweight and obesity,with AUB-O being the primary cause.Older age and the presence of uterine structural lesions were risk factors for requiring surgical treatment.

Objective:To explore the chain mediating role of self-management efficacy and self-perceived burden between family function and decision fatigue in gastric cancer patients.Methods:Convenience sampling was used to select 219 gastric cancer inpatients in Xinxiang Central Hospital of Henan Province from June 2023 to December 2024 as study subjects. Family Assessment Device, Chinese version of the Strategies Used by People to Promote Health, Self-Perceived Burden Scale, and Decision Fatigue Scale were used to conduct the survey. The chain mediating effect were tested using Model 6 in the SPSS PROCESS program.Results:Family function, self-management efficacy, self-perceived burden and decision fatigue scores of gastric cancer patients were (73.08±8.47), (90.15±14.33), (31.64±6.55), and (19.23±3.05), respectively. Univariate analysis showed that age, education level, per capita monthly family income, tumor stage and treatment method were the influencing factors of decision fatigue in gastric cancer patients, and the difference was statistically significant ( P<0.05). Correlation analysis showed that family function was negatively correlated with self-management efficacy ( P<0.05) and positively correlated with self-perceived burden and decision fatigue ( P<0.05), and self-management efficacy was negatively correlated with self-perceived burden and decision fatigue ( P<0.05), and self-perceived burden was positively correlated with decision fatigue ( P<0.05), and the differences of the above were statistically significant. Mediating effect analysis showed that family function positively predicted decision fatigue in gastric cancer patients, with a direct effect of 0.117, accounting for 62.57% of the total effect. Self-management efficacy and self-perceived burden realized the mediating effect between family function and decision fatigue through three mediating pathways. Mediating pathway 1 was family function → self-management efficacy → decision fatigue, with an effect value of 0.032, which accounted for 17.11% of the total effect. Mediating pathway 2 was family function→ self-perceived burden → decision fatigue, with an effect value of 0.026, which accounted for 13.90% of the total effect. Mediating path 3 was family function → self-management efficacy → self-perceived burden → decision fatigue, with an effect value of 0.012, accounting for 6.42% of the total effect. The total mediating effect was 0.070, accounting for 37.43% of the total effect. Conclusions:Family function can not only directly influence decision fatigue in gastric cancer patients, but also indirectly influence decision fatigue through the mediating role of self-management efficacy and self-perceived burden. Decision fatigue of gastric cancer patients could be reduced in the future by improving family function, increasing patients' self-management efficacy, and reducing their self-perceived burden.
