BACKGROUND:Epidemiological studies indicate that individuals with neurodegenerative diseases exhibit a comparatively lower risk of developing the majority of cancers.Although the precise mechanisms underlying this inverse correlation remain unclear,it is noteworthy that aberrant glucose metabolism,a pathological factor common to both conditions,may significantly contribute to this association.OBJECTIVE:To review the potential relationship between cancers and neurodegenerative diseases in glucose metabolism.METHODS:PubMed was searched for relevant literature using the search terms of"cancer,neurodegenerative diseases,Alzheimer's disease,Parkinson's disease,metabolic reprogramming,glucose metabolism,aerobic glycolysis,neuroprotection,aging,"and 136 articles were finally included for analysis.RESULTS AND CONCLUSION:Cancer and neurodegenerative diseases exhibit a profound pathological correlation at the level of glucose metabolism imbalance associated with aging.Cancer cells promote uncontrolled proliferation,invasion,and metastasis through the persistent activation of aerobic glycolysis,whereas neurodegenerative diseases are characterized by a reduction in aerobic glycolysis.Restoring aerobic glycolysis may confer neuroprotective effects and delay disease progression.The key nodes of glucose metabolism demonstrate a bidirectional regulatory pattern:metabolic regulators,which are significantly upregulated or aberrantly activated in cancer,are inhibited or functionally inactivated in neurodegenerative diseases.Mitochondria play a crucial role in mediating the aging process through the regulation of reactive oxygen species homeostasis and mitochondrial autophagy.They establish regulatory networks that connect cancer and neurodegenerative diseases,and maintaining their functional homeostasis is of paramount importance for disease prevention and treatment.

Objective:To explore the potential prognostic value of the HAMP(hepcidin)gene in gastric adenocarci-noma and its correlation with immune infiltration in gastric cancer.Methods:This study systematically analyzed the ex-pression characteristics of the HAMP gene using bioinformatics approaches based on mRNA data from 448 gastric ad-enocarcinoma tissues and non-tumor tissues in the TCGA database.Firstly,the cBioPortal platform was employed to analyze the genetic variation features of the HAMP gene,and the LinkedOmics database was used to evaluate the corre-lation between its methylation status and expression levels.Kaplan-Meier survival analysis with log-rank test was per-formed to assess the relationship between HAMP expression levels and patient prognosis.Furthermore,by integrating TIMER2.0 and TISIDB databases,we systematically evaluated the correlation between HAMP expression and immune-related genes as well as immune cell infiltration.Gene Set Enrichment Analysis(GSEA)was conducted to investigate HAMP-associated signaling pathway characteristics.Finally,STRING and Gepia databases were utilized to construct a protein-protein interaction network of HAMP and identify core interacting genes,comprehensively evaluating the role of HAMP in immune infiltration in gastric adenocarcinoma.Results:The expression level of HAMP was significantly higher in gastric adenocarcinoma tissues compared to normal tissues(P<0.01),and its elevated expression was strongly associ-ated with poor patient prognosis,manifested by significantly shorter overall survival(OS),progression-free survival(PFS),and post-progression survival(PPS)(all P<0.05).Genomic analysis revealed that HAMP mutations in gastric cancer were predominantly amplification-type,and its methylation level showed a positive correlation with mRNA expression(r=0.14,P<0.001).Immunological analysis demonstrated that high HAMP expression was significantly correlated with multiple key immune checkpoint molecules(PD-1:rho=0.274;PD-L1:rho=0.211;CTLA-4:rho=0.199,all P<0.001)and immune cell infiltration(dendritic cells:r=0.548;macrophages:r=0.414;neutrophils:r=0.374,all P<0.001).Pathway enrichment analy-sis indicated that the high HAMP expression group was significantly enriched in immune-related pathways including anti-gen presentation and NK cell-mediated cytotoxicity.Furthermore,protein-protein interaction network analysis identified core interacting genes such as TREM2 and TYROBP,suggesting that HAMP may participate in tumor immune regulation through specific molecular networks.Conclusion:HAMP is highly expressed in gastric cancer,and its high expression significantly reduces the survival time of gastric adenocarcinoma patients,demonstrating prognostic value.HAMP ex-pression is positively correlated with most immune-related genes in STAD and significantly associated with the abun-dance of multiple immune cell infiltration levels,serving as an independent prognostic factor related to immune infiltration.

Objective:To explore the clinical and genetic characteristics of X-linked intellectual disability associated with HUWE1 gene variants.Methods:A cases series study retrospectively analyzed the clinical data of 6 children with HUWE1 gene variants. The children were identified from the Third Affiliated Hospital of Zhengzhou University, the First Affiliated Hospital of Zhengzhou University, the First Affiliated Hospital of Henan University of Chinese Medicine, and Guangzhou Women and Children′s Medical Center of Guangzhou Medical University between April 2021 and July 2023.The data included sex, age, dysmorphic features, intellectual and motor development, seizure history, neuroimaging findings, family history, and genetic results was analyzed.Results:A total of 6 children, including 5 boys and 1 girl. The age of onset ranged from 1 day to 3 years. All children presented with varying degrees of intellectual disability, with or without motor developmental delay. Dysmorphic features were observed in 4 children, including microcephaly in 3 children. Short stature were observed in 3 children. One child was diagnosed with autism spectrum disorders and 1 child had seizures. Two boys had relevant maternal family histories of febrile seizures and mild intellectual disability, respectively. Abnormal neuroimaging findings were presented in 4 children, including cerebral dysplasia (1 child), prominent supratentorial ventricles (1 child), and mild white matter demyelination (2 children). Whole-exome sequencing identified 5 missense variants and 1 in-frame deletion variant. Five variants were novel and previously unreported (c.12290C>T, c.12701T>C, c.9875C>T, c.9641A>T and c.10313_10315del). The variants in 4 boys were maternally inherited, while the remaining 2 children had de novo variants. The child with the in-frame deletion variant (c.10313_10315del) presented with the most severe phenotype, exhibiting symptoms from 1 day of age, absent cognitive development, feeding difficulties, and congenital laryngeal chondrodysplasia. He was lost to follow-up at 3 months of age after treatment was withdrawn. The age at the last follow-up for the remaining 5 children ranged from 2 years and 10 months to 17 years. A boy with seizures died at 2 years and 10 months of age. The remaining 4 children were able to walk independently at the last follow-up, although their developmental progress was slow. Conclusions:HUWE1 gene related X-linked intellectual disability is characterized by varying degrees of developmental delay and intellectual disability, frequently accompanied by microcephaly, short stature, and occasionally by seizures and autism spectrum disorders. Missense variants are more common and the in-frame deletion variant appears to be associated with a particularly severe phenotypic presentation.

Objective:To explore the value of non-invasive habitat imaging (HI) multi-parametric MRI (mpMRI) in predicting the risk of prostate cancer (PCa).Methods:In this cross-sectional study, 220 patients with PCa confirmed by radical prostatectomy (RP) who underwent multi-parametric MRI (mpMRI) scanning at Xijing Hospital, Air Force Military Medical University from January 2018 to May 2024 were retrospectively collected. Patients were divided into a training set (154 cases) and a test set (66 cases) by simple random sampling in a 7∶3 ratio. Based on mpMRI imaging, the apparent diffusion coefficient (ADC), perfusion fraction (f), and mean kurtosis (MK) of each voxel were integrated. The K-means clustering algorithm was used to divide the PCa target lesions into habitat subregions, generate habitat maps, and calculate the proportion of each habitat subregion in the entire lesion. According to the 2019 International Society of Urological Pathology (ISUP) guidelines, patients were categorized into a low-risk group (ISUP≤2, 65 cases) and a high-risk group (ISUP≥3, 155 cases). The RP specimens were matched with the habitat map to identify corresponding habitat subregions, and the ISUP grade of each subregion was individually evaluated to calculate the detection rate of high-risk PCa patients. The logistic regression analysis was applied to identify the independent risk factors associated with PCa risk, and the HI-clinical imaging model and clinical imaging model were constructed. The efficacy of the models was assessed using receiver operating characteristic curve.Results:Based on the optimal cluster number, the habitat was divided into three subregions. Habitat 1 had lower ADC and f values and higher MK values, while habitat 2 had the opposite characteristics, and habitat 3 was intermediate. The proportion of habitat 1 in the high-risk group was 28.8%, in the low-risk group was 8.9%. In the training set, the comparison of habitat subregions with pathological results showed that the detection rate of high-risk lesions was 66.9% (103/154) in habitat 1, 25.3% (39/154) in habitat 2, and 47.4% (73/154) in habitat 3. The logistic regression analysis indicated that the proportion of habitat 1 ( OR=3.03, 95% CI 1.77-5.18, P<0.001), prostate-specific antigen ( OR=1.66, 95% CI 1.04-2.66, P=0.034), and the prostate imaging reporting and data system score ( OR=1.65, 95% CI 1.00-2.70, P=0.048) as independent risk factors for high-risk PCa. In the training set, the area under the curve (AUC) for predicting PCa risk was 0.854 (95% CI 0.789-0.920) for the HI-clinical imaging model and 0.779 (95% CI 0.701-0.856) for the clinical imaging model. In the test set, the AUC values were 0.809 (95% CI 0.693-0.895) and 0.738 (95% CI 0.619-0.856), respectively. Conclusion:HI based on mpMRI can effectively predict the risk of PCa.

Objective To explore the application effect of nursing intervention based on empow-erment theory in treatment of facial photoaging with fractional ablative fractional laser.Methods A total of 90 patients with facial photoaging who underwent fractional ablative fractional laser treatment were selected and divided into control group and observation group according to random number table method,with 45 cases in each group.The control group received routine nursing intervention,while the observation group received nursing intervention based on empowerment theory.The skin condi-tion,the incidence of adverse reactions,psychological state[Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS)]scores,and quality of life[Dermatology Life Quality Index(DLQI)]scores were compared between the two groups.Results After intervention,the percentages of skin characteristics such as enlarged facial pores,wrinkles,and spots in the observation group were higher than those in the control group;the incidence of adverse reactions in the observation group was lower than that in the control group(8.89％ versus 24.44％);the SAS scores,SDS scores,and total DLQI scores in the observation group were lower than those in the control group,with statistically sig-nificant differences(P＜0.05).Conclusion Nursing intervention based on empowerment theory can effectively improve the facial skin condition of patients with facial photoaging treated with fraction-al ablative fractional laser,reduce the incidence of adverse reactions,alleviate negative emotions,and enhance quality of life.

Objective:To analyze the current status of clinical trials of Chinese materia medica for the purpose of registration in China; To provide reference for the research and development of new TCM drugs.Methods:Clinical trials of Chinese materia medica/natural medicine registered in Drug Clinical Trial Registration and Information Disclosure Platform were retrieved from inception to December 31, 2024. Excel 2019 software was used to input and analyze the data such as the number of registered clinical trials, date of first publication, study status, field of indication, trial phases, sponsors, group leader, and design types.Results:A total of 1 137 Chinese materia medica clinical trials had been registered, accounting for 4.12% of the total number registered on the platform. Phase Ⅱ clinical trials accounted for the highest proportion (58.8%), and 99.7% of clinical trials conducted domestically. The sponsors were predominantly domestically pharmaceutical enterprises. These 1 137 clinical trials of Chinese materia medica clinical trials involved 752 drug categories, 28 dosage forms, and 796 varieties (the same class of drugs had different drug dosage forms), with capsules being the most common. The indications primarily focused on respiratory, digestive, cardio-cerebrovascular, neuropsychiatric, gynecological diseases. The group leader of clinical trials was distributed in 28 provinces, among which the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine as the group leader, undertook the most clinical trials of TCM. 89.9% of the clinical trials adopted the randomized controlled trial design, and only 31.9% of the clinical trials purchased insurance for the subjects.Conclusion:The research and development of new TCM drugs has entered a phase of vigorous development. Further efforts are still needed in establishing systematic guidelines for Chinese materia medica clinical trials, accelerating the internationalization of TCM, exploring innovative dosage forms and indications, and strengthening the protection of participants' rights.

Direct electrical stimulation of the human cortex can produce subjective visual sensations, yet these sensations are unstable. The underlying mechanisms may stem from differences in electrophysiological activity within the distributed network outside the stimulated site. To address this problem, we recruited 69 patients who experienced visual sensations during invasive electrical stimulation while intracranial electroencephalography (iEEG) data were recorded. We found significantly flattened power spectral slopes in distributed regions involving different brain networks and decreased integrated information during elicited visual sensations compared with the non-sensation condition. Further analysis based on minimum information partitions revealed that the reconfigured network interactions primarily involved the inferior frontal cortex, posterior superior temporal sulcus, and temporoparietal junction. The flattened power spectral slope in the inferior frontal gyrus was also correlated with integrated information. Taken together, this study indicates that the altered electrophysiological signatures provide insights into the neural mechanisms underlying subjective visual sensations.
