Metabolic reprogramming， as one of the core hallmarks of malignant tumors， plays a key role in the occurrence， development and treatment of breast cancer （BC）. Abnormal changes in glucose metabolism， amino acid metabolism， lipid metabolism， as well as the tricarboxylic acid （TCA） cycle and oxidative phosphorylation （OXPHOS） pathways significantly influence the pathogenesis and progression of BC. Studies have shown that various active components of traditional Chinese medicine （TCM） （such as berberine， matrine， quercetin， curcumin， etc.） and their compound formulations （e.g. Xihuang pill， Danzhi xiaoyao powder， Yanghe decoction， etc.） can inhibit the proliferation and migration of BC cells and induce apoptosis by regulating key metabolic pathways such as glycolysis， lipid synthesis， and amino acid metabolism. TCM demonstrates multi-target and holistic regulatory advantages in intervening in BC metabolic reprogramming， showing significant potential in modulating key molecules like hypoxia inducible factor-1α， hexokinase-2， pyruvate kinase M2， lactate dehydrogenase A， glucose transporter-1， fatty acid synthase， and signaling pathways such as AKT/mTOR. However， current researches still focus predominantly on glucose metabolism， with insufficient mechanistic studies on lipid metabolism， amino acid metabolism， the TCA cycle， and OXPHOS. The precise targets， molecular mechanisms， and clinical translation value of these interventions require further validation and clarification through more high-quality experimental studies and clinical trials.

AIM: To investigate the expression levels of follistatin-like protein 1(FSTL1)and a disintegrin and metalloproteinase with thrombospondin type 1 motif 13(ADAMTS13)in the serum of patients with proliferative diabetic retinopathy(PDR), and to analyze their predictive value for visual disability.METHODS:A prospective study. From January 2022 to September 2024, patients with diabetes retinopathy(DR)were selected from Fengfeng General Hospital of North China Medical and Health Group. They were divided into non-proliferative diabetes retinopathy(NPDR)group and PDR group. In the same period, simple type 2 diabetes(T2DM)patients were selected as T2DM group, and healthy people were selected as control group. Enzyme linked immunosorbent assay was used to detect serum levels of FSTL1 and ADAMTS13. Patients in the PDR group were followed up for 12 mo to observe the occurrence of visual disability, and were accordingly divided into a non-visual disability group and a visual disability group. Risk factors for visual disability in PDR patients were analyzed by Logistic regression, and the predictive value was assessed via receiver operating characteristic(ROC)curves and decision curve analysis(DCA).RESULTS: This study included 220 DR patients, including 119 cases in the NPDR group and 101 cases in the PDR group. There were 120 cases in the T2DM group and 120 cases in the control group. The control group had an age of 56.92±8.15 y, with 66 males and 54 females. The T2DM group had an age of 57.21±8.30 y, with 63 males and 57 females. The NPDR group had an age of 57.36±8.25 y, with 60 males and 59 females. The PDR group had an age of 57.45±8.22 y, with 53 males and 48 females. There were 68 patients without visual disability and 33 patients with visual disability in the PDR group. The non-visual disability group had a mean age of 57.26±8.14 y, including 35 males and 33 females. The visual disability group had a mean age of 57.85±8.37 y, including 18 males and 15 females. Diabetes duration was progressively longer in the T2DM, NPDR, and PDR groups. Levels of fasting plasma glucose(FPG), glycated hemoglobin(HbA1c), and FSTL1 progressively increased, while ADAMTS13 levels progressively decreased across the control, T2DM, NPDR, and PDR groups(all P<0.001). Within the PDR group, serum FSTL1 levels increased sequentially while ADAMTS13 levels decreased sequentially in patients with grade Ⅳ, Ⅴ and Ⅵ lesions(all P<0.001). The visual disability group had significantly longer diabetes duration and higher levels of FPG, HbA1c, and FSTL1, as well as lower ADAMTS13 levels, compared to the non-visual disability group(all P<0.001). The diabetes duration, FSTL1, ADAMTS13 were the influencing factors of visual disability in PDR patients(all P<0.001). ROC curve and DCA curve analysis showed that the predictive value of combined detection of serum FSTL1 and ADAMTS13 levels is higher than that of individual measurement(all P<0.05).CONCLUSION:PDR patients have higher serum FSTL1 levels and lower ADAMTS13 levels. Both are related to the severity of PDR. The combined measurement has a high predictive value for visual disability in PDR patients.

Objective:To investigate the value of a multi-parameter MRI nomogram model in evaluating the recurrence risk of hormone receptor (HR)-positive breast cancer.Methods:This study was a retrospective cross-sectional study. A retrospective analysis was conducted on the clinicopathological data (age, menopausal status, axillary lymph node metastasis, etc.) and imaging data of 220 patients with HR-positive breast cancer who underwent breast MRI examination and were pathologically confirmed at the Second Affiliated Hospital of Nantong University from January 2018 to December 2023. All patients underwent preoperative MRI examinations. Their MRI features were analyzed, and the maximum diameter of the lesion and the apparent diffusion coefficient (ADC) value were measured. Finally, the clinical treatment score (CTS5 score) after 5 years was calculated, and all patients were divided into a low recurrence risk (CTS5 score 3.13 points) and a medium to high recurrence risk (CTS5 score≥3.13 points) group. The patients were followed up through the electronic medical record system or by phone until December 31, 2024 to determine recurrence status. The patients were divided into the recurrence group and the non-recurrence group. The differences in clinicopathological data, MRI features and CTS5 scores between the recurrence group and the non-recurrence group were compared using independent sample t-tests, Mann-Whitney U tests or χ2 tests. Indicators with P0.05 in the univariate analysis were included in the multivariate logistic regression to screen the independent risk factors for predicting the recurrence of HR receptor-positive breast cancer, and a nomogram was constructed to establish the nomogram model. The receiver operating characteristic curves and the area under the curve (AUC) were used to evaluate the efficacy of the nomogram model in predicting the postoperative recurrence risk of patients with HR-positive breast cancer. The variance inflation factor (VIF) was used to evaluate the multicollinearity among independent variables. Calibration curves and decision curve analysis (DCA) were used to assess the fit and net clinical benefit of the nomogram model. Results:Among 220 patients with HR-positive breast cancer, 196 cases were in the non-recurrence group and 24 cases were in the recurrence group. There were statistically significant differences in the maximum diameter of the lesion, axillary lymph node metastasis, ADC value, CTS5 grouping, and CTS5 score between the recurrence group and the non-recurrence group ( P0.05). Multivariate logistic regression analysis showed that the maximum diameter of the lesion ( OR=1.110, 95% CI 1.169-1.503, P0.001), ADC value ( OR=0.993, 95% CI 0.993?0.989, P0.001), and axillary lymph node metastasis ( OR=8.842; 95% CI 2.120?36.884, P=0.003) were independent factors influencing postoperative recurrence in patients with HR-positive breast cancer, and a nomogram model was constructed based on this. VIF analysis showed that no significant multicollinearity was detected among the variables (VIF5). The AUC value of the nomogram model for predicting postoperative recurrence in patients with HR-positive breast cancer was 0.868 (95% CI 0.794-0.942), the sensitivity was 0.875, and the specificity was 0.781. The calibration curve showed that the prediction curve of this model for predicting postoperative recurrence in HR-positive breast cancer patients was basically consistent with the ideal curve trend. DCA showed that this model had a relatively high clinical benefit within the threshold probability range of 0.01% to 90.00%. Conclusion:The nomogram constructed based on multi-parameter MRI features can predict the postoperative recurrence risk of HR-positive breast cancer patients, with good consistency and predictive ability.

Objective To explore the mediating effect of negative emotion and rumination on the quality of discharge guidance and discharge readiness of patients after coronary artery bypass grafting.Methods A total of 288 patients who underwent coronary artery bypass surgery in the Second Affiliated Hospital of Nanchang University from February 2022 to February 2024 were selected as study objects.General data questionnaire,self-rating anxiety scale(SAS),self-rating depression scale(SDS),Chinese version of event related rumination inventory(CERRI),quality of discharge teaching scale(QDTS),readiness for hospital discharge scale(RHDS)were used to investigate,and Amos 24.0 structural equation model was used to analyze the chain mediation effect.Results A total of 288 questionnaires were sent out,and 280 valid questionnaires were recovered,with an effective recovery rate of 97.22％.The patients'SAS scores were(57.83±5.32)points,SDS scores were(63.31±4.97)points,CERRI total scores were(31.03±4.76)points,QDTS total scores were(116.78±9.22)points,and RHDS total scores were(79.30±7.21)points.The RHDS scores of patients who lived alone after discharge,paid at their own expense and had grade Ⅲ heart function were significantly lower than those of patients with nursing care,medical insurance payment and grade Ⅰ heart function after discharge(P<0.05).Anxiety was positively correlated with depression,intrusive rumination,but negatively correlated with purposive rumination,quality of discharge guidance and discharge readiness.Depression was positively correlated with intrusive rumination,but negatively correlated with purposive rumination,quality of discharge guidance and discharge readiness.Invasive rumination was negatively correlated with purposive rumination,quality of discharge guidance and discharge readiness.Purposive rumination was positively correlated with the quality of discharge guidance and discharge readiness.The quality of discharge guidance was positively correlated with discharge readiness(P<0.05).The chain-mediated model was well fitted,and the results showed that the quality of patients'discharge guidance could affect their discharge readiness,while negative emotions and rumination pathways also affected their discharge readiness(P<0.05).Conclusion The quality of discharge guidance can directly or indirectly affect the discharge readiness of patients after coronary artery bypass grafting through negative emotions and rumination,and there is a chain mediation effect.

Objective To explore the application value of the Plan-Do-Check-Act(PDCA)cycle in the refined whole-process management of low-value medical consumables.Methods Using the PDCA cycle as a framework,the Plan phase in-volved analyzing the causes of traceability difficulties for low-value medical consumables.The Do phase implemented multiple im-provement measures,including establishing standardized management systems,strengthening personnel supervision,creating a split-item tertiary inventory,and introducing the Unique Device Identification(UDI)system.The Check phase evaluated man-agement effectiveness by comparing data from June to December 2023 and June to December 2024.The Act phase refined institu-tional norms and operational processes through a closed-loop feedback mechanism.Results After PDCA management,the appli-cation time for low-value medical consumables[(6.16±1.47)min]and the collection time[(15.08±1.89)min]were signif-icantly shorter than before implementation(P＜0.001).The acceptance qualification rate increased from 92.96％to 99.11％.The application of the split-item tertiary inventory ensured synchronization between inventory deduction and billing data.Conclu-sion The PDCA cycle improves the traceability of low-value medical consumables through systematic quality improvement.Its dynamic feedback mechanism supports continuous improvement,providing an effective pathway for hospitals to achieve refined management and cost control.

Among international research institutions, North South University ( n=9) and University of Malaya ( n=9) led in publication output. A total of 67 core authors were identified in Chinese literature and 194 in the English literature. Analysis of high-frequency keywords showed that the research topics could be summarized as research types, occurrence mechanisms, negative effects, high-risk precursors, intervention strategies, negative effects and population differences. Chinese Nursing Research ( n=40) and Journal of Nursing Management ( n=186) published the most Chinese and English articles. Conclusions:The amount of research on workplace violence among nurses has generally increased in recent years. The mechanisms of occurrence, high-risk precursors, and intervention strategies are important research directions. It is still necessary to further deepen the research content in the future.

Objective:To investigate clinical characteristics and genetic variations in a case of self-improving collodion ichthyosis in the adult stage.Methods:An adult patient with clinically suspected self-improving collodion ichthyosis was collected from the Department of Dermatology, Henan Provincial People′s Hospital in April 2023. Clinical data were collected from the patient and her parents. Peripheral blood samples were obtained from them, and whole blood DNA was extracted. Whole-exome sequencing was performed to screen genetic variation sites, which were then verified by Sanger sequencing. The deleteriousness of the identified variants was assessed using pathogenicity analysis software.Results:The 54-year-old female patient presented with facial and neck flushing, mild dry skin on the trunk and limbs, sheepskin-like skin of the dorsal hand, and short fingers. Genetic testing identified two in-frame deletion mutations c.406_408del (p.E136del) and c.769_801del (p.H257_Q267del) in the non-repetitive region of the ALOX12B gene in the patient, which were inherited from her father and mother respectively. Bioinformatics analysis revealed that both genetic variations were deleterious pathogenic mutations.Conclusions:Two in-frame deletion mutations c.406_408del (p.E136del) and c.769_801del (p.H257_Q267del) were identified in the non-repetitive region of the ALOX12B gene in the patient with self-improving collodion ichthyosis, which may contribute to the clinical phenotype of the patient. The mutation c.769_801del had not been reported in literature.

Objective:To report a case of hereditary fibrosing poikiloderma with tendon contracture, myopathy, and pulmonary fibrosis (POIKTMP), and analyze the genotype-phenotype correlation through a literature review.Methods:The clinical manifestations and genetic testing results of a Chinese Han child with POIKTMP were reported. Relevant literature was searched in databases using ′FAM111B gene′, ′hereditary fibrosing poikiloderma with tendon contracture, myopathy, and pulmonary fibrosis′ or ′POIKTMP′ as keywords, and the clinical manifestations, mutation sites of the FAM111B gene, and the correlation between them were statistically analyzed.Results:A 6.5-year-old girl developed POIKTMP at 6 months of age. Dermatological examination showed irregular brown patches and dotted hypopigmentation on the face and neck, mainly on the forehead and around the mouth, telangiectasia on the cheeks and nose, pigmentation and hypopigmentation on the limbs and trunk, as well as sparse, pale eyebrows. A total of 39 cases of POIKTMP were retrieved, including this case, all of which had clinical data and were definitively diagnosed. Fourteen variants of the FAM111B gene had been reported, including 1 in-frame deletion variant and 13 missense variants. Among the 39 cases, the incidence of poikiloderma/photosensitivity/facial erythema/telangiectasia was 100% (39/39), alopecia was 87.2% (34/39), and that of hypohidrosis/heat intolerance was 82.1% (32/39). The incidence of extracutaneous manifestations was as follows: tendon contractures/digital sclerosis, 69.2% (27/39) ; elevated liver transaminases, 46.2% (18/39) ; muscle pain/weakness/amyotrophy, 43.6% (17/39). The incidence of eczema-like lesions, bullous lesions, and elevated liver transaminases was significantly higher in the young versus the adult group ( P < 0.05) . Conclusions:This case of POIKTMP was characterized by brown patches, hypopigmentation, and sparse eyebrows. POIKTMP is a progressive multisystem disorder with age-related clinical manifestations. Early genetic testing is crucial for evaluating potential complications and providing genetic counseling.
