Objective:To investigate the relationship between different states of cardiac function and their changes during the course of diabetic foot ulcers(DFU), and to evaluate their impact on patient prognosis.Methods:A retrospective analysis was conducted on 194 DFU patients who were rehospitalized at approximately 3-month intervals. Basic clinical data and cardiac function-related indicators were collected at baseline and follow-up. Patients were followed until death or until November 10, 2024. Outcomes including ulcer healing, recurrence, minor amputation, and death were recorded. Logistic regression models were used to analyze the effects of cardiac function status and its changes on these four outcomes. Results:After treatment, the proportion of patients with NYHA class Ⅱ-Ⅲ decreased significantly from 33.5% at baseline to 21.6%( P=0.009). Serum N-terminal pro-B-type natriuretic peptide(NT-proBNP) level also decreased after treatment compared with baseline [635.85(59.83, 453.28) pg/mL vs 728.67(81.48, 696.15) pg/mL, P=0.055]. Serum NT-proBNP level was significantly higher in the death group compared to the survival group( P=0.002). The proportion of DFU patients with baseline NYHA class Ⅱ-Ⅲ was significantly higher than that in those with class Ⅰ( P=0.012). Regression analysis showed that an improvement in NT-proBNP levels was associated with a lower risk of DFU recurrence( OR=0.378, 95% CI 0.183-0.779, P=0.008), and improvement in NYHA class was associated with a lower mortality risk( OR=0.074, 95% CI 0.020-0.275, P<0.001). Conclusion:Cardiac function status and its changes during the treatment of DFU patients have strong prognostic implications, particularly in predicting the risk of recurrence and death outcomes.

ObjectiveTo analyze the temporal distribution characteristics of crisis calls and eight major counseling issues to the Shanghai mental health hotline, and to provide recommendations for improving hotline management. MethodsDescriptive statistics were used to analyze 1 106 crisis calls and the calls of eight major counseling issues to the Shanghai mental health hotline across months, time periods and weeks from October 2021 to September 2023, and the chi-square test was used to analyze whether there was any difference in the distribution of 1 106 crisis calls and the calls of eight major counseling issues across months, time periods and weeks. ResultsThere were significant differences in the number of crises calls across different months (χ²=87.816, P<0.05), time periods (χ²=161.848, P<0.05), and weekly distributions (χ²=63.329, P<0.05). The highest number of calls occurred in September, while January had the lowest. The peak call times were between 18:00‒20:00, with the fewest calls occurring between 3:00‒5:00. The day of the week with the highest number of calls was Saturday, while Wednesday had the lowest. Among the different types of counselling issues in crisis calls, the highest number of calls were related to mental disorders, while the fewest calls were related to COVID-19. ConclusionCrisis calls to the Shanghai mental health hotline are concentrated at specific times, indicating that relevant organizations should optimize resource allocation based on this time distribution.

Background::Epigenetics, and especially DNA methylation, contributes to the pathogenesis of sporadic amyotrophic lateral sclerosis (SALS). This study aimed to investigate the role of DNA methylation in SALS using whole blood of SALS patients.Methods::In total, 32 SALS patients and 32 healthy controls were enrolled in this study. DNA was isolated from whole blood collected from the participants. DNA methylation profiles were generated using Infinium MethylationEPIC BeadChip.Results::We identified 34 significant differentially methylated positions (DMPs) in whole blood from SALS patients, compared with the healthy controls. Of these DMPs, five were hypermethylated and 29 were hypomethylated; they corresponded to 13 genes. For the DMPs, ATAD3B and BLK were hypermethylated, whereas DDO, IQCE, ABCB1, DNAH9, FIGN, NRP1, TMEM87B, CCSAP, ST6GALNAC5, MYOM2, and RUSC1-AS1 were hypomethylated. We also identified 12 differentially methylated regions (DMRs), related to 12 genes (NWD1, LDHD, CIS, IQCE, TNF, PDE1C, LGALS1, CSNK1E, LRRC23, ENO2, ELOVL2, and ELOVL2-AS1). According to data from the Kyoto Encyclopedia of Genes and Genomes database, DNAH9 and TNF are involved in the amyotrophic lateral sclerosis (ALS) pathway. Correlation analysis between clinical features and DNA methylation profiling indicated that the methylation level of ELOVL2 and ARID1B was positively associated with the age of onset ( r = 0.86, adjust P = 0.001) and disease duration ( r = 0.83, adjust P = 0.01), respectively. Conclusions::We found aberrant methylation in DMP- and DMR-related genes, implying that many epigenetic alterations, such as the hypomethylation of DNAH9 and TNF, play important roles in ALS etiology. These findings can be helpful for developing new therapeutic interventions.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder, stimultaneously affecting cerebral pyramidal cells, motor nuclei in the brain stem, anterior horn cells of the spinal cord, and the pyramidal tract. The early diagnosis of ALS is very difficult. At present, it still lacks efficacious therapy. Its prognosis is poor, with the median survival time for about 3-5 years. The study and discovery of ALS-specific biomarkers for early diagnosis are critical to shorten diagnostic delay, explore and elucidate pathogenesis, monitor disease progression and predict prognosis. In recent years, studies have shown that the neurofilament plays an important role in the aspects above, and at present, it is considered as the most clinically valuable and promising biomarker for ALS. Thus, the article provides a review about research on neurofilament and ALS.

OBJECTIVE:To compare the differences between artificially cultivated and wild Xinjiang Artemisia rupestris,and screen the different components. METHODS:HPLC-MS was adopted to establish the fingerprints of artificially cultivated and wild Xinjiang A. rupestris from different origin and harvest time. Principal component analysis was conducted by Marker ViewTM soft-ware and SIMCA-P 11.5 software,the characteristics of principal components were analyzed,difference variable was screened, and different components of artificially cultivated and wild varieties were obtained. RESULTS:Fingerprints of 22 batches of A. rup-estris(12 batches of wild varieties,10 batches of artificially cultivated varieties)were established. According to the principal com-ponent analysis,artificially cultivated and wild varieties were well grouped,with obvious differences;the principal components of artificially cultivated varieties with different harvest time showed certain difference,mainly before and after flowering,concentrat-ing in to-be flowering and full flowering periods. Wild varieties from different origins had obvious regional difference,showing cer-tain differences in composition and content. 268 variables were found in matrix of positive ion mode and 155 in negative ion mode. 28 groups of variables were extracted by difference variable,and 19 variables were determined. CONCLUSIONS:Artificially culti-vated and wild varieties have obvious difference in principal component,mainly in flowering period and picking places. It can pro-vide theoretical basis for the standardized cultivation and origin protection of Xinjiang A. rupestris.

Objective To explore the relationship between behavioral psychological symptoms in Alzheimer' s dementia(AD) patients and region-specific alterations in cerebral blood flow. Methods 60 patients with AD randomly selected from a psychiatric outpatient department and 30 randomly selected healthy elderly community controls were administered the Mini-Mental State Exam (MMSE). All subjects underwent a perfusion CT scan to assess blood perfusion in brain regions of interest. The AD subjects were administered the behavioral patholigy in alzheimer' s disease(BEHAVE-AD) Rating Scale classified as mild, moderate or severe based on the results of the Clinical Dementia Rating scale. Results The most incidence was conduct disorder and the next was delusion.The score was 81.7% and 58.3% in turn. The conduct disorder score was higher in the severe demented group than in the mildly and moderate demented group(P＜0. 05). The delusion score was higher in the moderate demented group than that in the mildly demented group(P＜0.05). The time to peak(TTP)scores in the four groups of subjects were significantly different in the bilateral hippocampal formation, anteroinferior subiculum and entorhinal area. The TTP score was significantly higher in the moderately demented group than that in the mildly demented group and the control group(P＜0. 05 ). Correlation analysis identified a positive correlation between conduct disorder, delusions and TTP in cerebral heteroplasia cortex (P ＜ 0. 05 ), also identified a negative correlation between mood disorder and TTP(P＜0. 05 ). Conclusion The conduct disorder,delusions and mood disorder in AD are associated with the chronicity ischemia of cerebral heteroplasia cortex leading to neural conduction disorders.
