Illness narratives serve as an entry point that combines patients’ micro-level experiences with macro-level power structures in the medical field and are also an important aspect of medical ethics and narrative medicine research. Based on the existing meaning of illness narratives， the significant importance of focusing on the broader concept of illness narratives was emphasized. Drawing on Foucault’s theory of power， it was found that illness narratives， beyond reflecting the pain caused by the disease itself， should also focus on the dominant role of power structures in the modern medical field over illness narratives， and explore how to reduce the domination of power. Inspired by the concepts of ethics and survival aesthetics in Foucault’s late thought， this paper explored the possibility of transcending power domination and reconstructing subjectivity through self-technology reinforcement such as patient illness narratives in the medical field. Finally， from the perspectives of both medical service provision and patient needs， illness narratives and the practice of narrative medicine were reflected and summarized， hoping that narrative medicine can contribute to the return of individual subjectivity with a broad ethical meaning in the medical field.

Objective:To systematically analyze the incidence and influencing factors of frailty in elderly patients with hematologic malignancies.Methods:Research on frailty in elderly patients with hematologic malignancies was retrieved from Chinese and English databases such as China National Knowledge Infrastructure, Wanfang Data, PubMed, and Web of Science. The search period was from database establishment to August 23, 2024. Two researchers screened the included studies, conducted quality assessment, and extracted data. Meta-analysis was conducted using Stata 18 and RevMan 5.4.Results:A total of seven studies were included, encompassing 19 076 elderly hematologic malignancy patients, with a frailty incidence of 59% [95% CI (0.48, 0.69) ]. Meta-analysis revealed that age [ MD=4.31, 95% CI (3.67, 4.96) ], gender [ OR=0.88, 95% CI (0.83, 0.93) ], alcohol consumption [ OR=1.67, 95% CI (1.15, 2.44) ], self-care ability [ MD=-1.79, 95% CI (-3.17, -0.41) ], anemia [ OR=6.67, 95% CI (2.94, 15.14) ], infection [ OR=1.81, 95% CI (1.16, 2.84) ], and neuropathy [ OR=2.52, 95% CI (1.38, 4.61) ] were the influencing factors of frailty in elderly patients with hematologic malignancies. Conclusions:The incidence of frailty is high in elderly patients with hematologic malignancies. Elderly patients with hematologic malignancies who are older, female, consume alcohol, have low self-care ability, anemia, infections, and neuropathy are prone to frailty. Healthcare providers can conduct early screening and intervention for high-risk populations of frailty based on risk factors to improve the quality of life for elderly hematologic malignancy patients.

Objective:To investigate the distribution of CGG repeat numbers in the FMR1 gene among reproductive-age women in China, providing data reference for carrier screening and genetic counseling of Fragile X syndrome. Methods:This cross-sectional study recruited 16 610 reproductive-age women from 12 medical institutions between July 2022 and October 2023. Peripheral venous blood samples (3 mL) were collected, and genomic DNA was extracted. The number of CGG repeats in the FMR1 gene was determined using the triplet-primed polymerase chain reaction (TP-PCR) combined with capillary electrophoresis technology. Statistical analyses were performed to assess the prevalence and distribution of CGG repeat expansions. Results:Among 16 610 women of childbearing age, 5 684 (34.220%) women had the same number of CGG repeats in the two alleles of FMR1 gene, and 10 926 (65.780%) women had different numbers of repeats in the two alleles. Among the 33 220 FMR1 alleles in 16 610 women of reproductive age, the most common CGG repeat numbers were 29 [48.645% (16 160/33 220)] and 30 [26.276% (8 729/33 220)], while the most frequent CGG genotype was CGG 29/29 [24.726% (4 107/16 610)]. The CGG repeat numbers of FMR1 gene were normal in 16 498 women (99.326%). Among the 112 women (0.674%) with CGG repeat abnormities, 96 (0.578%) women were classified as intermediate carriers, 15 (0.090%) as premutation carriers, and 1 (0.006%) as a full mutation carrier, whose CGG genotype was (36, >200). Conclusion:In the general reproductive-age female population in China, the normal CGG repeat numbers of the FMR1 gene account for 99.326%, while the intermediate carrier rate is 0.578%, and the combined carrier rate of the premutation and full mutation types is 0.096%.

Objective To explore the potential categories of exercise perception in elderly hip arthroplasty(HA)patients,analyze the prediction factors of different categories,and provide references for clinical nursing.Methods A convenience sampling method was used to select elderly HA patients treated in 6 orthopedic wards of 2 tertiary A hospitals in Guilin from October 2024 to February 2025.The general data questionnaire,Exercise Benefits and Barriers Perception Scale for Hip/Knee Throplasty Patients,Tampa Scale of Kinesiophobia,the 5-Factor Modified Frailty Index,and Self-Efficacy for Rehabilitation Outcome Scale were used for investigation.Latent profile analysis was used to identify the potential categories of exercise perception of elderly HA patients,and decision tree model was used to explore the core predictive factors of different profile.Results 222 valid questionnaires were collected,with an effective response rate of 96.52％.A total of 222 elderly HA patients were divided into 3 profiles:high benefit-low barrier group(19.82％),low benefit-high barrier group(22.07％),and mild barrier group(58.11％).Frailty,kinesophobia,rehabilitation self-efficacy,residence,educational level and daily exercise were significant predictors of latent profiles(P＜0.05),and the frailty was located in the root node of the decision tree model.Conclusion The level of exercise perception in elderly HA patients needs to be improved,and shows population heterogeneity.Medical staff should prioritize interventions for low benefit-high barrier and mild-barrier groups,implementing targeted strategies based on profile characteristics and predictive factors to improve their exercise perception.

Extensive evidence has demonstrated that glucagon-like peptide-1 receptor agonists (GLP-1RAs) can ameliorate obesity. Our previous studies revealed that (Ex-4)₂-Fc, a long-acting GLP-1RA we developed, depends on the leptin pathway to treat obesity. However, the mechanisms linking (Ex-4)₂-Fc and leptin resistance remain largely unclear. To address this question, we explored the mechanism of GLP-1RAs from the perspective of the gut microbiota, as increasing evidence indicates an important link between the gut microbiota and obesity. This study aimed to explore the potential role of the gut microbiota in the treatment of GLP-1RAs. We found that (Ex-4)₂-Fc treatment reshaped obesity-induced gut microbiota disturbances and substantially increased the abundance of Akkermansia muciniphila (Am). In addition, (Ex-4)₂-Fc did not respond well in antibiotic-treated (ATB) Obese mice. Subsequent studies have shown that this defect can be overcome by gavage with Am. In addition, we found that Am enhanced (Ex-4)₂-Fc therapy by producing the metabolite inosine. Inosine regulates the macrophage adenosine A2A receptor (A2A) pathway to indirectly reduce leptin levels in adipocytes Thus, elucidating the role of metabolites in regulating the leptin pathway will provide new insights into GLP-1RAs therapy and may lead to more effective strategies for guiding the clinical use of antidiabetic agents.

The prevalence of summer endogenous fever is closely related to the climate of summer.Based on Li Dongyuan's yin-fire theory,this article proposed that summer-heat,irregular diet,excessive consumption of cold foods,poor living habits,and summer damp-heat internal invasion damaging the spleen can all lead to the generation of yin-fire,thereby causing endogenous fever.The core pathogenesis of summer endogenous fever lies in spleen deficiency with yang collapse,which results into the blockage of qi movement and the production of yin-fire.The yin-fire persists throughout the entire course of the disease.Treatment of summer endogenous fever should focus on eliminating yin-fire,primarily by addressing the spleen via boosting qi and raising yang to restore the spleen's ascending and stomach's descending functions,thereby dispersing yin-fire.Clearing heat and resolving dampness can purge yin-fire and then the spleen qi's circulation is restored.By analyzing the pathological changes of dampness accumulation into phlegm,fire-heat damaging yin and liver stagnation with kidney deficiency,the disease progression can be predicted.Correspondingly,comprehensive therapy of resolving phlegm,nourishing yin,soothing liver,and tonifying kidney can be employed to prevent further deterioration.Based on Li Dongyuan's yin-fire theory,Shengyang Yiwei Decoction(mainly composed of Astragali Radix,Pinelliae Rhizoma,Ginseng Radix et Rhizoma,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Angelicae Pubescentis Radix,Saposhnikoviae Radix,Paeoniae Radix Alba,Notopterygii Rhizoma et Radix,Citri Reticulatae Pericarpium,Poria,Bupleuri Radix,Alismatis Rhizoma,Atractylodis Macrocephalae Rhizoma,and Coptidis Rhizoma)can be used as a fundamental prescription to treat summer endogenous fever caused by yin-fire,with modifications tailored to specific clinical presentations.This theoretical exploration may provide a reference for the clinical management of summer endogenous fever.

Purpose To investigate the diagnostic value of immunohistochemical(IHC)and molecular markers in diffuse pleural mesothelioma(DPM).Methods A total of 114 cases of DPM were retrospectively analyzed for clinical and imaging manifestations,histologic subtype and tumor grade.The positivity rates of Calretinin,WT-1,CK5/6,MC,D2-40,UPK3B,and GATA3 were assessed by IHC,and the loss rates of BAP-1 and MTAP were determined.The concordance between MTAP IHC and p16 gene fluorescence in situ hybridization(FISH)status was calculated,a-long with the sensitivity and specificity of MTAP IHC relative to p16 FISH.Results Among the 114 DPM patients,66(57.9％)were male and 48(42.1％)were female,with a mean age of 58.1 years(range 16-85 years).Imaging predominantly demonstrated pleural effusion and multiple pleural nodules(55.3％,63/114).Histologically,epitheli-oid,sarcomatoid and biphasic subtypes accounted for 88(77.2％),17(14.9％)and 9(7.9％)cases,respectively.Within the epithelioid group,low and high-grade tumors numbered 69(78.4％)and 19(21.6％),respectively.In epithelioid DPM,the highest IHC positivity rates were observed for Calretinin(92.4％,81/88),D2-40(90.0％,79/88)and WT-1(90.0％,79/88).In sarcomatoid DPM,D2-40(76.5％,13/17),WT-1(64.7％,11/17),and Cal-retinin(29.4％,5/17)showed the greatest positivity.UPK3B was positive in epithelioid(59.1％,39/66)and bi-phasic cases(66.7％,4/6),but was absent in sarcomatoid tumors(0/12).Among all DPM cases,loss rates were 47.3％(53/112)for BAP-1 and 19.2％(20/104)for MTAP by IHC,p16 gene deletion by FISH was 31.5％(34/108);Concordance between MTAP IHC and p16 FISH was 81.0％(81/100);MTAP IHC had a specificity of 95.5％(64/67)and sensitivity of 51.5％(17/33)relative to p16 FISH.Additionally,GATA3 was highly expressed in sarco-matoid DPM(76.5％,13/17).UPK3B positivity differed significantly between thoracoscopic DPM(59.2％,32/54)and percutaneous biopsy samples(36.7％,11/30)in epithelioid DPM(P＜0.05).WT-1 positivity was higher in thoracoscopic than percutaneous samples of sarcomatoid DPM(90.0％ vs 28.6％,P=0.009).Conclusion Calreti-nin,D2-40,and WT-1 are highly sensitive mesothelial markers and should serve as first-line IHC stains in DPM diag-nosis.UPK3B is diagnostically valuable in epithelioid DPM,GATA3 may complement the diagnosis of sarcomatoid DPM,and MTAP IHC can be used as a surrogate or adjunct to p16 FISH.

Objective:To evaluate the clinical efficacy, safety and treatment persistence of upadacitinib in Crohn's disease (CD) patients.Methods:The single-center retrospective cohort study was conducted. The patients with moderate-to-severe active CD initiating upadacitinib therapy from November 2023 to November 2024 in Nanjing Drum Tower Hospital were collected through searching the electronic medical records and paper-based patient databases. The primary outcome was the clinical remission rate at week 12. Secondary outcomes included the clinical response rate at week 12; clinical response and remission rates at weeks 4, 24 and 48; biomarker (fecal calprotectin or C-reactive protein) remission rates at all time points; as well as endoscopic remission and response rates, treatment persistence and safety evaluation.Results:A total of 44 CD patients were included, comprising 24 males (54.5%) and 20 females (45.5%). The median age was 33 (25, 40) years. The baseline Crohn's disease activity index (CDAI) score was 260.5 (225.9, 550.0) points. Patients had previously received a median of 2 (1, 2) biologic treatments. All 44 patients completed the 12-week induction therapy. With a median follow-up of 30.00 (16.25, 46.25) weeks, the clinical remission rate was 50.0% (22/44) at week 12. The clinical remission rate, clinical response rate, and biomarker remission rate were 52.3% (23/44), 88.6% (39/44) and 72.7% (32/44) respectively at week 4, and the clinical response rate and biomarker remission rate were 88.6% (39/44) and 77.2% (34/44) respectively at week 12. The clinical remission rates, clinical response rates and biomarker remission rates evolved to 43.3% (13/30), 86.7% (26/30) and 80.0% (24/30) at week 24, and further to 44.4% (4/9), 77.8% (7/9) and 77.8% (7/9) at week 48. During the follow-up period, 13 CD patients completing endoscopic evaluation, endoscopic remission and response rates were 30.8% and 23.1% respectively. CD-related surgery rate was 4.5% (2/44). Safety analysis demonstrated that the overall adverse events rate was 56.8% (25/44) including 7 patients with serious adverse events. A total of 8 patients discontinued treatment, among which 3 were due to primary loss of response, 1 due to secondary loss of response, 2 due to drug-related adverse events alone, and 2 due to concurrent primary loss of response and adverse events. The Kaplan-Meier curve for treatment persistence showed that among 39 CD patients who achieved clinical response at week 12, the continued treatment rates were 90.3% at week 12 and 85.3% at week 24 of follow-up. Two patients (5.6%) received dose escalation of upadacitinib, both of whom achieved clinical remission.Conclusion:Real-world research data demonstrate that upadacitinib exhibits significant clinical efficacy and a favorable safety profile in the treatment of moderate-to-severe active CD patients with prior biologic exposure, and no new unexpected adverse events are identified.

OBJECTIVE To observe the expressions of micro ribonucleic acid-129-5p(miR-129-5p),interleukin-6(IL-6)/signal transducer and activator of transcription 3 gene(STAT3)/helper T cell 17(Th17)signaling path-ways in peripheral blood of the sepsis children complicated with pulmonary infection and analyze the clinical signif-icance.METHODS A total of 123 sepsis children who were complicated with pulmonary infection and were treated in the 971st Hospital of the Navy of The Chinese People's Liberation Army,the 904 Hospital of the Joint Logis-tics Support Force of the People's Liberation Army and Qingdao Women's and Children's Hospital from Jan.2020 to Dec.2023 were assigned as the sepsis complicated with pulmonary infection group,meanwhile,55 sepsis children who were not complicated with pulmonary infection were chosen as the simple sepsis group.The expres-sion levels of miR-129-5p,IL-6 mRNA,STAT3 mRNA and Th17 mRNA in peripheral blood mononuclear cells(PBMCs)were statistically analyzed.Receiver operating characteristics(ROC)curves were drawn to analyze the efficiencies of miR-129-5p and IL-6/STAT3/Th17 pathways in prediction of poor prognosis of the sepsis children with pulmonary infection.RESULTS The miR-129-5p level of the sepsis complicated with pulmonary infection group was lower than that of the simple sepsis group,while the levels of IL-6 mRNA,STAT3 mRNA and Th17 mRNA of the sepsis complicated with pulmonary infection group were higher than those of the simple sepsis group(all P＜0.05).With the aggravation of illness condition,the miR-129-5p level was reduced,and the levels of IL-6 mRNA,STAT3 mRNA and Th17 mRNA were elevated(all P＜0.05).The miR-129-5p level of the poor prog-nosis group was lower than that of the favorable prognosis group,while the levels of IL-6 mRNA,STAT3 mRNA and Th17 mRNA of the poor prognosis group was higher than those of the favorable prognosis group(all P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of miR-129-5p was the largest(0.887)in prediction of the poor prognosis of the sepsis children complicated with pulmonary infection(P＜0.05).CONCLUSION The sepsis children complicated with pulmonary infection show the decline of expression level of peripheral blood miR-129-5p and enhancement of activation degree of IL-6/STAT3/Th17 pathways,which can be used as the indexes for assessment of illness condition and as auxiliary indexes for assessment of prognosis.
