While cranial radiotherapy effectively kills tumor cells and significantly prolongs patient survival, it often leads to progressive cognitive decline. To date, the specific mechanisms underlying radiation-induced cognitive decline have not been fully elucidated, which greatly limits the development of related therapeutic strategies. Therefore, this article provides a comprehensive analysis of post-radiation changes in neurogenesis, neuronal synaptic plasticity, myelin injury plasticity, and parenchymal cells such as microglia in the brain, systematically elucidates the potential mechanisms of radiation-induced cognitive decline, and summarizes feasible therapeutic approaches. These findings provide a solid foundation for developing novel strategies to mitigate radiation-induced cognitive decline.

The gut microbiota is regarded as the "eighth organ" of the human body and plays a critical regulatory role in the occurrence and progression of various diseases. Ulcerative colitis （UC） is a chronic inflammatory bowel disease with a complex etiology and a tendency toward recurrent episodes. In recent years， studies have shown that gut microbiota dysbiosis plays a key role in its pathological processes. Meanwhile， an increasing number of studies have demonstrated that imbalances in the gut microbiota and abnormalities in its metabolites are closely associated with the development of atrial fibrillation （AF）. Although UC and AF belong to diseases of the digestive system and cardiovascular system， respectively， both exhibit systemic inflammatory characteristics and are often accompanied by gut microbiota dysregulation and abnormal metabolic products. However， systematic investigations into the mechanisms by which gut microbiota-derived metabolites act in these two diseases remain limited. Based on this， the present study adopts literature review and theoretical analysis methods， taking the "gut microbiota-gut-heart" axis as the entry point， to systematically summarize the signaling networks of three key classes of metabolites， i.e.， short-chain fatty acids （SCFAs）， bile acids （BAs）， and trimethylamine N-oxide （TMAO）， in the comorbidity mechanism of UC and AF. The findings indicate that these metabolites may activate key inflammatory pathways， such as NF-κB and NLRP3， thereby synergistically mediating intestinal barrier dysfunction and systemic inflammation and constructing a potential comorbidity network. On this basis， potential intervention strategies for the treatment of UC-AF comorbidity， including probiotic intervention and fecal microbiota transplantation， are further discussed. This study aims to provide new theoretical evidence and research perspectives for prevention and treatment strategies of cross-system diseases.

ObjectiveTo explore the effect of tele-supervised home-based pulmonary music therapy on respiratory function, exercise capacity and clinical symptoms in patients with chronic obstructive pulmonary disease (COPD). MethodsA total of 96 COPD patients admitted to the Second People's Hospital of Lianyungang from January, 2023 to June, 2024 were selected. They were divided into control group and observation group (48 cases each) using block randomization combined with a random number table. The control group received routine treatment and nursing intervention, while the observation group added tele-supervised home-based pulmonary music therapy, for six months. Evaluations were conducted before intervention and one, three and six months after intervention. ResultsThree cases in the control group and two in the observation group dropped out. Compared to the control group, the observation group was better in forced expiratory volume in one second percentage of predicted (FEV₁%) level six months after intervention (χ² = 10.481, P < 0.001), maximal inspiratory pressure three months (Z = -2.045, P = 0.044) and six months (Z = -3.643, P = 0.033) after intervention, maximal expiratory pressure three months (Z = 2.111, P = 0.036) and six months (Z = 4.025, P < 0.001) after intervention, exercise capacity one month (t = 2.266, P = 0.028), three months (t = 3.943, P = 0.028) and six months (t = 6.703, P < 0.001) after intervention, fatigue scores three months (Z = -4.352, P < 0.001) and six months (Z = -5.718, P < 0.001) after intervention, clinical symptoms three months (t = -2.698, P = 0.007) and six months (t = -2.898, P = 0.003) after intervention, and clinical control levels three months (t = -3.402, P < 0.001) and six months (t = -5.036, P < 0.001) after intervention.

Objective : To investigate the effect of laminarin(LAM) on nonproliferative diabetes retinopathy by high throughput sequencing(RNA-seq). Methods : The diabetes model was established by intraperitoneal injection of streptozotocin(STZ), and the effect of LAM on diabetic mice was observed.C57BL/6 mice were randomly divided into three groups: Control group, Model group, and LAM group, with 8 mice in each group. After 8 weeks of modeling, the LAM group received a 4-week intraperitoneal injection of LAM treatment. Changes in blood glucose and body weight of the three groups of mice were recorded, HE staining was performed to examine retinal lesions, and RNA-seq was used to identify differentially expressed genes(DEGs) in diabetic retinopathy(DR) under the action of STZ and LAM. Results : STZ successfully established the model of DR, and LAM reduced the blood sugar in diabetic mice to a certain extent and improved the pathological morphology of retinal structural looseness in diabetic mice. After RNA-seq analysis of DEGs, it was found that there were a total of 214 DEGs in the retina of the Model group mice compared to the Control group. Enrichment analysis revealed that DR could exacerbate the lesions through the PI3K Akt signaling pathway. There were a total of 42 DEGs in the retina of the Model group and LAM group mice, and enrichment showed that LAM improved the lesions through the neutrophil extracellular trap pathway. Early growth response factor 1(Egr1), FBJ osteosarcoma oncogene(Fos), nuclear receptor subfamily 4A member 1(Nr4a1), and salt-induced kinase 1(Sik1) were regulated by STZ, and LAM significantly regulated their expression, which might be closely related to LAM′s treatment of diabetic retinopathy. Conclusion DEGs can exacerbate the severity of diabetic retinopathyviathe PI3K-Akt signaling pathway. LAM can mitigate diabetic retinopathyviathe neutrophil extracellular trap pathway. Egr1, Fos, Nr4a1, and Sik1 are key genes involved in LAM treatment of STZ-induced DR.

Objective:To explore the relationships among psychological resilience,spiritual health,and illness uncertainty in cancer patients,and to analyze the mediating role of disease uncertainty.Methods:The cancer patients were selected by convenience sampling method from Feb 2024 to May 2024 in the Department of Oncology of a Grade Ⅲ-A general hospital in Wuhu City.Data were collected using a general information questionnaire,the Mishel Uncertainty in Illness Scale(MUIS),the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale(FACIT-SP-12,Chinese version),and the Connor-Davidson Resilience Scale(CD-RISC-10).Pearson correlation analysis was conducted to assess the relationships among psychological resilience,illness uncertainty,and spiritual health.The mediating effect of illness uncertainty was tested using Hayes'PROCESS Model 4 and the Bootstrap method.Results:The total scores of spiritual health,psychological resilience and illness uncertainty of cancer patients was(25.11±7.19),(24.36±6.75)and(67.75±13.06),respectively.The spiritual health was positively correlated with psychological resilience(r=0.415,P＜0.01)and negatively correlated with illness uncertainty(r=-0.398,P＜0.01).The psychological resilience was negatively correlated with illness uncertainty(r=-0.668,P＜0.01).Illness uncertainty partially mediated the relationship between psychological resilience and spiritual health,accounting for 35.29%of the total effect.Conclusions:The spiritual health of cancer patients is at a moderate level.Enhancing psychological resilience and reducing illness uncertainty can alleviate psychological burden and improve spiritual health,thereby promoting overall quality of life.

Left ventricular hypertrophy(LVH)is one of the common target organ damage of hypertension."Yang leading to qi and yin leading to formation"is the basic form of human material and energy metabolism and disease development.The pathogenesis of hypertension LVH is inseparable from the imbalance of yin and yang.The deficiency of"yang leading to qi"leads to the decline of zang-fu function,deficiency of qi and blood,and the excess of"yin leading to formation"leads to the accumulation of pathological products such as phlegm and fluid,both of which are important pathogenesis of hypertensive LVH.Hypertensive LVH can be seen at the beginning of yin deficiency and yang hyperactivity,liver hyperactivity and wind movement,qi and blood deficiency,and later yin and yang deficiency,phlegm and blood stasis interjunction and other symptoms.In the treatment of hypertensive LVH,the early stage should be based on nourishing yin and extinguishing wind,regulating qi and blood,and the later stage should be based on supplementing yin and yang,expelling phlegm and promoting blood,so as to improve the clinical efficacy of TCM treatment of this disease.

Objective To explore the relationship between sarcopenia and related indicators and quality of life in the elderly hypertensive population.Methods A total of 104 elderly patients with hypertension who were hospitalized in the Second People's Hospital of Hefei from January to December 2024 were selected as research subjects.The general information,biochemical indicators,blood pressure variability,skeletal muscle mass index,grip strength and walking speed of patients were collected,and the quality of life was evaluated by World Health Organization quality of life-brief version(WHOQOL-BREF).Patients were divided into non-sarcopenia group(n=46)and sarcopenia group(n=58)based on the presence or absence of sarcopenia.The clinical data and quality of life of patients in two groups were compared.Results There were statistically significant differences in gender,age,body mass index,serum albumin,24-hour systolic blood pressure coefficient of vatiation(SCV),24-hour diastolic blood pressure coefficient of vatiation(DCV)and WHOQOL-BREF score between two groups of patients(P＜0.05).Sarcopenia was negatively correlated with the quality of life in the physical and psychological domains(P＜0.05),but not correlated with the quality of life in the social relationship and environmental domains(P＞0.05).Both 24-hour SCV and 24-hour DCV were risk factors for quality of life in the physiological and psychological domains,while serum albumin was a protective factor for the quality of life in the physiological and psychological domains(P＜0.05).Conclusion Sarcopenia,serum albumin,24-hour SCV and 24-hour DCV in elderly hypertensive population are all correlated with the quality of life in the physiological and psychological domains.Attention should be paid to the physical function training of such people,ensuring adequate nutritional intake,actively detecting and reducing blood pressure variability to improve the overall quality of life.

Purpose To investigate the clinicopathological features and differential diagnosis of anaplastic large-cell lymphoma(ALCL)with the small cell variant.Methods The clinical data of 15 cases of small cell variant of ALCL were retrospectively analyzed.Hematoxylin-eosin staining,immunohistochemistry,EBER in situ hybridization,TCR and IgG rearrangement were performed.The clinicopathological features,prognosis and differential diagnosis were summarized with review of the literature.Results Among the 15 cases of small cell ALCL,5 were females and 10 were males,with a male-to-female ratio of 2:1.Among the 15 cases of small cell ALCL,14 were systemic ALCL[(12 cases of ALK+),and the age range was 5-63 years old(median age 20 years);There were 2 cases of ALK(-),aged more than 60 years],and 1 case of ALCL of primary cutaneous ALK(-).Microscopic features were dominated by small to medium-sized tumor cells,with irregular nuclear membranes,inconspicuous nucleoli,and a lack of or few iconic large cells.Immunohistochemically:3 cases were ALK-negative and 12 cases were ALK-positive.Tumor cells were CD30 positive in 14/15 cases,CD3 positive in 7/15 cases,CD2 positive in 2/6 cases,CD4 positive in 5/11 cases,CD5 positive in 2/8 cases,CD7 positive in 4/6 cases,CD8 positive in 1/8 cases,TIA-1 positive in 7/7 cases,Granzyme B positive in 4/6 cases and EMA positive in 6/7 cases.CD20 was negative in all cases.Immuno-globulin IgG and TCR gene rearrangement were negative in case 4 and case 11.Case 13 was positive for TCR rear-rangement and negative for immunoglobulin IgG.Twelve of the 15 patients were followed up for 0.7-165 months(me-dian,7 months),3 patients were lost to follow-up and 7 patients died.Conclusion Small cell variant ALCL is easily misdiagnosed as an inflammatory or infectious disease.A group of antibodies,including CD30 and ALK,should be routinely used in routine work,especially in young patients with systemic symptoms and leukemia manifestations or in small biopsies,to reduce misdiagnosis and missed diagnosis.
