Health-related quality of life in Chinese SLE patients: evidence from 1568 SLE patients and 2610 healthy controls.

OBJECTIVE: To investigate the effects of systemic lupus erythematosus (SLE) on health-related quality of life (HRQOL), the relationship between disease activity and HRQOL, and potential factors affecting HRQOL in Chinese SLE patients. METHODS: This study recruited 1568 patients and 2610 controls to explore the effects of SLE on HRQOL. The association between disease activity and HRQOL, and the influencing factors of HRQOL were determined in 1568 patients. Then, we prospectively followed 1096 patients to explore the association between reduced disease activity and improved HRQOL, and the influencing factors of improved HRQOL. The Short-Form 36 (SF-36) and SLE disease activity index (SLEDAI) were used to evaluate HRQOL and disease activity. RESULTS: Chinese SLE patients had lower HRQOL than controls in all domains (P < 0.001), especially in role-physical (RP) and role-emotional (RE). Compared with SLE patients from outside China, the HRQOL of Chinese patients appeared to be higher in mental component summary (MCS) but lower in RP and RE. SLEDAI was negatively correlated with HRQOL, which was validated using the results of a follow-up study, where SLEDAI reduction was positively associated with HRQOL improvements (P < 0.05). Furthermore, personality, life nervous and experiences of adverse life events may influence HRQOL and HRQOL improvements. CONCLUSION: SLE significantly affected the HRQOL of Chinese patients, especially in RP and RE. Disease activity was negatively correlated with HRQOL. We also found for the first time some factors affecting HRQOL, which can be regarded as the basis for improving the HRQOL of SLE patients.

Functional outcomes of different surgical treatments for common peroneal nerve injuries: a retrospective comparative study.

BACKGROUND: This study aims to assess the recovery patterns and factors influencing outcomes in patients with common peroneal nerve (CPN) injury. METHODS: This retrospective study included 45 patients with CPN injuries treated between 2009 and 2019 in Jing'an District Central Hospital. The surgical interventions were categorized into three groups: neurolysis (group A; n = 34 patients), nerve repair (group B; n = 5 patients) and tendon transfer (group C; n = 6 patients). Preoperative and postoperative sensorimotor functions were evaluated using the British Medical Research Council grading system. The outcome of measures included the numeric rating scale, walking ability, numbness and satisfaction. Receiver operating characteristic (ROC) curve analysis was utilized to determine the optimal time interval between injury and surgery for predicting postoperative foot dorsiflexion function, toe dorsiflexion function, and sensory function. RESULTS: Surgical interventions led to improvements in foot dorsiflexion strength in all patient groups, enabling most to regain independent walking ability. Group A (underwent neurolysis) had significant sensory function restoration (P < 0.001), and three patients in Group B (underwent nerve repair) had sensory improvements. ROC analysis revealed that the optimal time interval for achieving M3 foot dorsiflexion recovery was 9.5 months, with an area under the curve (AUC) of 0.871 (95% CI = 0.661-1.000, P = 0.040). For M4 foot dorsiflexion recovery, the optimal cut-off was 5.5 months, with an AUC of 0.785 (95% CI = 0.575-0.995, P = 0.020). When using M3 toe dorsiflexion recovery or S4 sensory function recovery as the gold standard, the optimal cut-off remained at 5.5 months, with AUCs of 0.768 (95% CI = 0.582-0.953, P = 0.025) and 0.853 (95% CI = 0.693-1.000, P = 0.001), respectively. CONCLUSIONS: Our study highlights the importance of early surgical intervention in CPN injury recovery, with optimal outcomes achieved when surgery is performed within 5.5 to 9.5 months post-injury. These findings provide guidance for clinicians in tailoring treatment plans to the specific characteristics and requirements of CPN injury patients.

Development of a machine learning model and nomogram to predict seizures in children with COVID-19: a two-center study.

OBJECTIVE: This study aimed to use machine learning to evaluate the risk factors of seizures and develop a model and nomogram to predict seizures in children with coronavirus disease 2019 (COVID-19). MATERIAL AND METHODS: A total of 519 children with COVID-19 were assessed to develop predictive models using machine learning algorithms, including extreme gradient boosting (XGBoost), random forest (RF) and logistic regression (LR). The performance of the models was assessed using area under the receiver operating characteristic curve (AUC) values. Importance matrix plot and SHapley Additive exPlanations (SHAP) values were calculated to evaluate feature importance and to show the visualization results. The nomogram and clinical impact curve were used to validate the final model. RESULTS: Two hundred and seventeen children with COVID-19 had seizures. According to the AUC, the RF model performed the best. Based on the SHAP values, the top three most important variables in the RF model were neutrophil percentage, cough and fever duration. The nomogram and clinical impact curve also verified that the RF model possessed significant predictive value. CONCLUSIONS: Our research indicates that the RF model demonstrates excellent performance in predicting seizures, and our novel nomogram can facilitate clinical decision-making and potentially offer benefit for clinicians to prevent and treat seizures in children with COVID-19.

A map of the spatial distribution and tumour-associated macrophage states in glioblastoma and grade 4 IDH-mutant astrocytoma.

Tumour-associated macrophages (TAMs) abundantly infiltrate high-grade gliomas and orchestrate immune response, but their diversity in isocitrate dehydrogenase (IDH)-differential grade 4 gliomas remains largely unknown. This study aimed to dissect the transcriptional states, spatial distribution, and clinicopathological significance of distinct monocyte-derived TAM (Mo-TAM) and microglia-derived TAM (Mg-TAM) clusters across glioblastoma-IDH-wild type and astrocytoma-IDH-mutant-grade 4 (Astro-IDH-mut-G4). Single-cell RNA sequencing was performed on four cases of human glioblastoma and three cases of Astro-IDH-mut-G4. Cell clustering, single-cell regulatory network inference, and gene set enrichment analysis were performed to characterize the functional states of myeloid clusters. The spatial distribution of TAM subsets was determined in human glioma tissues using multiplex immunostaining. The prognostic value of different TAM-cluster specific gene sets was evaluated in the TCGA glioma cohort. Profiling and unbiased clustering of 24,227 myeloid cells from glioblastoma and Astro-IDH-mut-G4 identified nine myeloid cell clusters including monocytes, six Mo/Mg-TAM subsets, dendritic cells, and proliferative myeloid clusters. Different Mo/Mg-TAM clusters manifest functional and transcriptional diversity controlled by specific regulons. Multiplex immunostaining of subset-specific markers identified spatial enrichment of distinct TAM clusters at peri-vascular/necrotic areas in tumour parenchyma or at the tumour-brain interface. Glioblastoma harboured a substantially higher number of monocytes and Mo-TAM-inflammatory clusters, whereas Astro-IDH-mut-G4 had a higher proportion of TAM subsets mediating antigen presentation. Glioblastomas with a higher proportion of monocytes exhibited a mesenchymal signature, increased angiogenesis, and worse patient outcome. Our findings provide insight into myeloid cell diversity and its clinical relevance in IDH-differential grade 4 gliomas, and may serve as a resource for immunotherapy development. © 2022 The Pathological Society of Great Britain and Ireland.

High levels of TIMP1 are associated with increased extracellular matrix stiffness in isocitrate dehydrogenase 1-wild type gliomas.

Glioma progression is accompanied with increased tumor tissue stiffness, yet the underlying mechanisms are unclear. Herein, we employed atomic force microscopy analysis to show that tissue stiffness was higher in isocitrate dehydrogenase (IDH)-wild type gliomas than IDH-mutant gliomas. Bioinformatic analyses revealed that tissue inhibitor of metalloproteinase-1 (TIMP1) was one of the preferentially upregulated genes in IDH-wild type gliomas as compared to IDH-mutant gliomas, and its higher expression indicated worse prognosis of glioma patients. TIMP1 intensity determined by immunofluorescence staining on glioma tissues positively correlated with glioma tissue stiffness. Mechanistically, TIMP1 expression was positively correlated with the gene expression of two predominant extracellular matrix components, tenascin C and fibronectin, both of which were also highly expressed in IDH-wild type gliomas. By introducing IDH1-R132H-containing vectors into human IDH1-wild type glioma cells to obtain an IDH1-mutant cell line, we found that IDH1 mutation increased the TIMP1 promoter methylation through methylation-specific PCR. More importantly, IDH1-R132H mutation decreased both the expression of TIMP1, fibronectin, tenascin C, and the tumor tissue stiffness in IDH1-mutant glioma xenografts in contrast to IDH1-wild type counterparts. Moreover, TIMP1 knockdown in IDH-wild type glioma cells inhibited the expression of tenascin C and fibronectin, and decreased tissue stiffness in intracranial glioma xenografts. Conclusively, we revealed an IDH mutation status-mediated mechanism in regulating glioma tissue stiffness through modulating TIMP1 and downstream extracellular matrix components.

Overexpression of carnitine palmitoyltransferase 1A promotes mitochondrial fusion and differentiation of glioblastoma stem cells.

Glioma stem cells (GSCs) are self-renewing tumor cells with multi-lineage differentiation potential and the capacity of construct glioblastoma (GBM) heterogenicity. Mitochondrial morphology is associated with the metabolic plasticity of GBM cells. Previous studies have revealed distinct mitochondrial morphologies and metabolic phenotypes between GSCs and non-stem tumor cells (NSTCs), whereas the molecules regulating mitochondrial dynamics in GBM cells are largely unknown. Herein, we report that carnitine palmitoyltransferase 1A (CPT1A) is preferentially expressed in NSTCs, and governs mitochondrial dynamics and GSC differentiation. Expressions of CPT1A and GSC marker CD133 were mutually exclusive in human GBMs. Overexpression of CPT1A inhibited GSC self-renewal but promoted mitochondrial fusion. In contrast, disruption of CPT1A in NSTCs promoted mitochondrial fission and reprogrammed NSTCs toward GSC feature. Mechanistically, CPT1A overexpression increased the phosphorylation of dynamin-related protein 1 at Ser-637 to promote mitochondrial fusion. In vivo, CPT1A overexpression decreased the percentage of GSCs, impaired GSC-derived xenograft growth and prolonged tumor-bearing mice survival. Our work identified CPT1A as a critical regulator of mitochondrial dynamics and GSC differentiation, indicating that CPT1A could be developed as a molecular target for GBM cell-differentiation strategy.

Roseicella aerolata sp. nov., isolated from bioaerosols of electronic waste.

A novel Gram-stain-negative, non-motile, spherical-shaped and facultatively anaerobic bacterial strain, designated as GB24T was isolated from bioaerosols of an E-waste dismantling site in Guiyu, Guangdong Province, South PR China. Growth occurred at 15-40 °C (optimum 37 °C), pH 5.5-9.5 (optimum 7.0), and up to 0.5 % NaCl (w/v) under aerobic conditions, GB24T was characterized taxonomically and phylogenetically. The sole isoprenoid quinone detected was ubiquinone-10 (Q-10). The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, three unidentified glycolipids, one unidentified phospholipid, and one unidentified aminolipid. Carotenoid pigments were produced. The major cellular fatty acids (> 10 % of total fatty acids) were C17 : 1ω6c (51.5 %) and summed feature 8 (13.5 %, comprising C18 : 1ω7c and/or C18 : 1ω6c). Phylogenetic analysis based on 16S rRNA gene sequence and draft genome grouped strain GB24T into the genus Roseicella. GB24T was most closely related to Roseicella frigidaeris DB1506T with 97.5 % 16S rRNA gene sequence similarity. The draft genome of GB24T comprised 6 153 170 bp with a DNA G+C content of 71.5 %. The average nucleotide identity (ANI) and in silico DNA-DNA hybridization (isDDH) values between GB24T and DB1506T were 83.2 % (Ortho ANI), 83.3 % [ANI by blast (ANIb)] and 27.0 %, respectively. Further genomic analysis of GB24T revealed the secondary metabolite clusters of terpene and phosphonate, which indicate the capacity for malleobactin (14 %) and phosphinothricin (6 %) tripeptide production. On the basis of the genotypic, chemotaxonomic and phenotypic results, GB24T represents a novel species, for which the name Roseicella aerolata sp. nov. is proposed. The type strain of Roseicella aerolata is GB24T (= GDMCC 1.2169T = JCM 34449T).

Poor cardiovascular health status among Chinese women.

BACKGROUND: Systematic investigation and analysis of cardiovascular health status (CVHS) of Chinese women is rare. This study aimed to assess CVHS and atherosclerotic cardiovascular disease (ASCVD) burden in the Chinese women physicians (CWP) and community-based non-physician cohort (NPC). METHODS: In this prospective, multicenter, observational study, CVHS using the American Heart Association (AHA) defined 7 metrics (such as smoking and fasting glucose) and ASCVD risk factors including hypertension, hyperlipidemia and type-2 diabetes were evaluated in CWP compared with NPC. RESULTS: Of 5832 CWP with a mean age of 44 ± 7 years, only 1.2% achieved the ideal CVHS and 90.1% showed at least 1 of the 7 AHA CVHS metrics at a poor level. Total CVHS score was significantly decreased and ASCVD risk burden was increased in postmenopausal subjects in CWP although ideal CVHS was not significantly influenced by menopause. Compared to 2596 NPC, fewer CWP had ≥ 2 risk factors (8% vs. 27%, P < 0.001); CWP scored significantly higher on healthy factors, a composite of total cholesterol, blood pressure, fasting glucose (P < 0.001), but, poorly on healthy behaviors (P < 0.001), specifically in the physical activity component; CWP also showed significantly higher levels of awareness and rates of treatment for hypertension and hyperlipidemia, but, not for type-2 diabetes. CONCLUSION: Chinese women's cardiovascular health is far from ideal and risk intervention is sub-optimal. Women physicians had lower ASCVD burden, scored higher in healthy factors, but, took part in less physical activity than the non-physician cohort. These results call for population-specific early and improved risk intervention.

Gut microbiota in obstructive sleep apnea-hypopnea syndrome: disease-related dysbiosis and metabolic comorbidities.

Gut microbiota alterations manifest as intermittent hypoxia and fragmented sleep, thereby mimicking obstructive sleep apnea-hypopnea syndrome (OSAHS). Here, we sought to perform the first direct survey of gut microbial dysbiosis over a range of apnea-hypopnea indices (AHI) among patients with OSAHS. We obtained fecal samples from 93 patients with OSAHS [5 < AHI ≤ 15 (n=40), 15 < AHI ≤ 30 (n=23), and AHI ≥ 30 (n=30)] and 20 controls (AHI ≤ 5) and determined the microbiome composition via 16S rRNA pyrosequencing and bioinformatics analysis of variable regions 3-4. We measured fasting levels of homocysteine (HCY), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α). Results revealed gut microbial dysbiosis in several patients with varying severities of OSAHS, reliably separating them from controls with a receiver operating characteristic-area under the curve (ROC-AUC) of 0.789. Functional analysis in the microbiomes of patients revealed alterations; additionally, decreased in short-chain fatty acid (SCFA)-producing bacteria and increased pathogens, accompanied by elevated levels of IL-6. Lactobacillus levels correlated with HCY levels. Stratification analysis revealed that the Ruminococcus enterotype posed the highest risk for patients with OSAHS. Our results show that the presence of an altered microbiome is associated with HCY among OSAHS patients. These changes in the levels of SCFA affect the levels of pathogens that play a pathophysiological role in OSAHS and related metabolic comorbidities.

[Toxicity-reducing effect of compatibility of Tripterygium and licorice in animals: systematic review].

The aim of this paper was to systematically evaluate the toxicity-reducing effect of Tripterygium-licorice in animal experiments,and also to provide evidence for basic research on the toxicity reduction of Tripterygium wilfordii. The PubMed,EMbase,Web of Science,CBM,CNKI and Wan Fang Databases from their establishment to August 31 th,2018 were searched. Two independent reviewers screened the papers,extracted the data,assessed the risk of bias using SYRCLE assessment tool and conducted Meta-analysis with Rev Man 5. 3 software. A total of 10 papers involving 31 studies were finally included,15 studies of which were used for Meta-analysis. Four studies were included for chronic hepatotoxicity animal model. In experimental group( 34 animals),Tripterygium was administered at dose of 0. 09-0. 1 mg·kg-1·d-1,and glycyrrhizic acid was administered at dose of 90-100 mg·kg-1,both for 2 weeks; in control group( 34 animals),glycyrrhizic acid was replaced with equal volume of normal saline. Eleven studies were included for acute hepatotoxicity animal model. In experimental group( 66 animals),glycyrrhizic acid was administered at dose of 75-480 mg·kg-1 for 7 days,then glycyrrhizic acid was stopped,and Tripterygium began to be administered at dose of 0. 6-1. 0 mg·kg-1 per 24 h or 48 h for a total of 1-2 times; in control group( 66 animals),glycyrrhizic acid was replaced with equal volume of normal saline or corresponding solvent. The results of Meta-analysis showed that in both chronic hepatotoxicity animal model and acute hepatotoxicity animal model,the transaminase levels in the experimental group were lower than those in the control group( P < 0. 05). Subgroup analysis of acute hepatotoxicity animal model showed that the transaminase levels in the experimental group were lower than those in the control group for every subgroup except " glycyrrhizic acid 75 mg·kg-1" subgroup. However,in terms of the mean difference( MD) and confidence interval( CI),there was no significant difference in transaminase decline between each subgroup. Low dose of glycyrrhizic acid( 90-100 mg·kg-1) has a toxicity-reduction effect on chronic hepatotoxicity induced by tripterygium( 0. 09-0. 10 mg·kg-1). Middle and high doses of glycyrrhizic acid( 120-480 mg·kg-1) have a toxicity-reduction effect on acute hepatotoxicity induced by tripterygium( 0. 6-1. 0 mg·kg-1),but with no significant dose-effect relationship.

[Identification and function analysis of target group for cardioprotection of Baoyuan decoction].

Baoyuan decoction (BYD) is a well-known traditional Chinese medicine formula for coronary heart disease with Qi deficiency. However, the detailed pharmacological mechanism of BYD is still unknown because of its complicated chemical compositions. In this study, we synthesized a kind of solid beads with benzophenone groups on its surface. Benzophenone can be activated and chemically cross-linked with the C-H bonds of the chemical compositions in BYD (BYD beads) under UV activation. We thus captured all the target proteins from mouse heart tissue lysates by using BYD beads. Based on proteomics analysis, we discovered totally 46 potential binding target proteins, most of which were located in mitochondria. KEGG analysis revealed that these target proteins were mainly associated with TCA cycle and amino acid metabolism signaling pathways, suggesting that the cardioprotection of BYD might be associated with regulating mitochondrial function and energy production. Moreover, JC-1 staining analysis also confirmed the protective effect of BYD on mitochondrial damage. In summary, our findings elucidated the potential mechanism of BYD on cardioprotection through "target fishing" strategy, and further explained its traditional efficacy in the molecular level. In addition, we also provide an approach for investigating the target group of complicated compositions in Chinese herbal formula. This novel method may provide a methodological reference for exploring the pharmacological mechanism of traditional Chinese formula in the future.

[Clinical application evaluation of Guidelines for Diagnosis and Treatment of Cancer in Traditional Chinese Medicine].

This study aims to evaluate the adaptability and applicability of Guidelines for the Diagnosis and Treatment of Cancer in Traditional Chinese Medicine. The assessment methods included adaptability assessment and applicability assessment. The adaptability assessment was based on the questionnaire survey to evaluate the familiarity, utilization, quality, and clinical application of the Guidelines; applicability assessment was based on the prospective observation of 853 clinical cases to investigate the applicability and effect of the Guidelines, including effectiveness, economy and safety. Statistical analysis for basic description, construction of different comparison groups for cross or hierarchical statistical test, multi-factor analysis, and confounding factors were used in the study. Adaptability assessment results showed that 63.03% of TCM doctors considered guidelines as good or very good applicability and 4.24% of TCM doctors considered guidelines with very poor applicability in clinical practice. For the applicability evaluation, TCM doctors considered that the "overall efficacy and technology level", "satisfactory degree" and "adaptability in clinical practice" of the guideline were 85.46%, 80.43% and 69.40% respectively. The results showed that guideline was well known among TCM doctors, especially junior TCM doctors. Adaptability and applicability of Guidelines were totally good but the quality and adaptability of the intervention schemes were still week, so the quality of Guidelines should be improved by revision.

Associations between plasma total homocysteine, blood pressure stages and pulse wave velocity in Chinese rural community population.

The aim of the study was to examine the associations among plasma total homocysteine (tHcy) and blood pressure (BP) stages and brachial-ankle pulse wave velocity (ba-PWV) in a Chinese rural community population. In this cross-sectional study, 2148 rural community subjects with normotension and mild hypertension (HTN) were classified into four groups according to ba-PWV level. Multivariate regression showed that ba-PWV was significantly and independently correlated with tHcy (ß = 5.32, p < 0.001) in the entire study population. Moreover, ba-PWV showed a significant increase with increasing plasma tHcy level in subjects with both high normal BP and grade 1 HTN (p < 0.05). Compared with optimal BP stage, ba-PWV was significantly associated with high normal BP stage (ß = 193, p < 0.001) and grade 1 HTN (ß = 413, p < 0.001).There was a statistical interaction effect between high normal BP stage and optimal BP stage (p = 0.045). The similar result was found between subjects with optimal BP and those with grade 1 HTN (p = 0.037). In conclusion, tHcy was independently correlated with ba-PWV in subjects with high normal BP and grade 1 HTN. High normal BP and grade 1 HTN may worsen the impact of tHcy on arterial stiffness in a Chinese rural community population.

[Effect of allitridum on remodeling of the transient outward potassium current of ventricular myocytes of spontaneously hypertensive rats].

We aimed to study the effect of allitridum (All) on the transient outward potassium current (Ito) of ventricular myocytes of spontaneously hypertensive rats (SHR). Totally 30 male SHRs were randomly divided into three groups: low-dose All group (7.5 mg·kg(-1)), high-dose All group (15.0 mg·kg(-1)) and normal saline group. The other 10 sex and age matched Wistar-kyoto rats (WKY) were also taken as control group (WKY group). All animals received i.p. administration for 8 weeks. The dual enzymatic method was used to separate single ventricular myocyte from animals. Patch-clamp technique was used to record Ito and analyze the effect of All on the current. It was shown that the left ventricular hypertrophy of SHR was reversed significantly by All. Furthermore, the density of Ito was recovered in both high and low dose All groups. The peak current densities of Ito were enhanced from 18.23±3.64 to 25.17±2.86 pA/pF (P<0.01) and 36.47±5.42 pA/pF (P<0.01) at +50 mV by All 7.5 mg·kg(-1) and 15.0 mg·kg(-1), respectively, which was not significantly different with WKY group. The effect was associated with positive shift of the steady-state, close-state inactivation, and shortened recovery from inactivation of Ito. It is concluded that All decreases the remodeling of Ito of ventricular hypertrophic myocytes of SHR.

A randomized controlled trial of single point acupuncture in primary dysmenorrhea.

BACKGROUND: Acupuncture is often used for primary dysmenorrhea. But there is no convincing evidence due to low methodological quality. We aim to assess immediate effect of acupuncture at specific acupoint compared with unrelated acupoint and nonacupoint on primary dysmenorrhea. METHODS: The Acupuncture Analgesia Effect in Primary Dysmenorrhoea-II is a multicenter controlled trial conducted in six large hospitals of China. Patients who met inclusion criteria were randomly assigned to classic acupoint (N = 167), unrelated acupoint (N = 167), or non-acupoint (N = 167) group on a 1:1:1 basis. They received three sessions with electro-acupuncture at a classic acupoint (Sanyinjiao, SP6), or an unrelated acupoint (Xuanzhong, GB39), or nonacupoint location, respectively. The primary outcome was subjective pain as measured by a 100-mm visual analog scale (VAS). Measurements were obtained at 0, 5, 10, 30, and 60 minutes following the first intervention. In addition, patients scored changes of general complaints using Cox retrospective symptom scales (RSS-Cox) and 7-point verbal rating scale (VRS) during three menstrual cycles. Secondary outcomes included VAS score for average pain, pain total time, additional in-bed time, and proportion of participants using analgesics during three menstrual cycles. FINDINGS: Five hundred and one people underwent random assignment. The primary comparison of VAS scores following the first intervention demonstrated that classic acupoint group was more effective both than unrelated acupoint (-4.0 mm, 95% CI -7.1 to -0.9, P = 0.010) and nonacupoint (-4.0 mm, 95% CI -7.0 to -0.9, P = 0.012) groups. However, no significant differences were detected among the three acupuncture groups for RSS-Cox or VRS outcomes. The per-protocol analysis showed similar pattern. No serious adverse events were noted. CONCLUSION: Specific acupoint acupuncture produced a statistically, but not clinically, significant effect compared with unrelated acupoint and nonacupoint acupuncture in primary dysmenorrhea patients.

The research landscape of ferroptosis in neurodegenerative disease: a bibliometric analysis.

Background: Ferroptosis, a newly proposed concept of programmed cell death, has garnered significant attention in research across different diseases in the last decade. Despite thorough citation analyses in neuroscience, there is a scarcity of information on ferroptosis research specifically related to neurodegenerative diseases. Method: The Web of Science Core Collection database retrieved relevant articles and reviews. Data on publications, countries, institutions, authors, journals, citations, and keywords in the included studies were systematically analyzed using Microsoft Excel 2019 and CiteSpace 6.2.R7 software. Result: A comprehensive analysis and visualization of 563 research papers on ferroptosis in neurodegenerative diseases from 2014 to 2023 revealed emerging research hotspots and trends. The number of annual publications in this field of study has displayed a pattern of stabilization in the early years of the decade, followed by a notable increase in the later years and peaking in 2023 with 196 publications. Regarding publication volume and total citations, notable research contributions were observed from countries, institutions, and authors in North America, Western Europe, and China. Current research endeavors primarily focus on understanding the intervention mechanisms of neurodegenerative diseases through the ferroptosis pathway and exploring and identifying potential therapeutic targets. Conclusion: The study highlights key areas of interest and emerging trends in ferroptosis research on neurodegenerative diseases, offering valuable insights for further exploration and potential directions for diagnosing and treating such conditions.
