Vitamin D deficiency may increase the risk of acute kidney injury in patients with diabetes and predict a poorer outcome in patients with acute kidney injury.

BACKGOUND: People with diabetes are much more likely to develop acute kidney injury (AKI) than people without diabetes. Low 25-hydroxy-vitamin D [25(OH)D] concentrations increased the risk of AKI in specific populations. Few studies have explored the relationship between the 25(OH)D level and AKI in patients with diabetes. We conducted this study to investigate the relationship between the plasma level of 25(OH)D and the risk of AKI in patients with diabetes, and to evaluate whether the 25(OH)D level could be a good prognostic marker for AKI progression. METHODS: A total of 347 patients with diabetes were retrospectively reviewed. The primary endpoint was the first event of AKI. The secondary endpoint is need-of-dialysis. AKI patients were further followed up for 6 months with the composite endpoint of end-stage renal disease (ESRD) or all-cause death. Kaplan-Meier survival analysis and Cox proportional hazards models were used. RESULTS: During a median follow-up of 12 weeks (12.3 ± 6.7), 105 incident AKI were identified. The middle and high tertiles of baseline 25(OH)D levels were associated with a significantly decreased risk of AKI and dialysis compared to the low tertile group (HR = 0.25, 95% CI 0.14-0.46; HR = 0.24, 95% CI 0.13-0.44, respectively, for AKI; HR = 0.15; 95% CI 0.05-0.46; HR = 0.12; 95% CI 0.03-0.42, respectively, for dialysis). Sensitivity analysis revealed similar trends after excluding participants without history of CKD. Furthermore, AKI patients with 25(OH)D deficiency were associated with a higher risk for ESRD or all-cause death (HR, 4.24; 95% CI, 1.80 to 9.97, P < 0.001). CONCLUSION: A low 25 (OH) vitamin D is associated with a higher risk of AKI and dialysis in patients with diabetes. AKI patients with 25(OH)D deficiency were associated with a higher risk for ESRD or all-cause death.

Leveraging Ensemble Models and Follow-up Data for Accurate Prediction of mRS Scores from Radiomic Features of DSC-PWI Images.

Predicting long-term clinical outcomes based on the early DSC PWI MRI scan is valuable for prognostication, resource management, clinical trials, and patient expectations. Current methods require subjective decisions about which imaging features to assess and may require time-consuming postprocessing. This study's goal was to predict multilabel 90-day modified Rankin Scale (mRS) score in acute ischemic stroke patients by combining ensemble models and different configurations of radiomic features generated from Dynamic susceptibility contrast perfusion-weighted imaging. In Follow-up studies, a total of 70 acute ischemic stroke (AIS) patients underwent magnetic resonance imaging within 24 hours poststroke and had a follow-up scan. In the single study, 150 DSC PWI Image scans for AIS patients. The DRF are extracted from DSC-PWI Scans. Then Lasso algorithm is applied for feature selection, then new features are generated from initial and follow-up scans. Then we applied different ensemble models to classify between three classes normal outcome (0, 1 mRS score), moderate outcome (2,3,4 mRS score), and severe outcome (5,6 mRS score). ANOVA and post-hoc Tukey HSD tests confirmed significant differences in model style performance across various studies and classification techniques. Stacking models consistently on average outperformed others, achieving an Accuracy of 0.68 ± 0.15, Precision of 0.68 ± 0.17, Recall of 0.65 ± 0.14, and F1 score of 0.63 ± 0.15 in the follow-up time study. Techniques like Bo_Smote showed significantly higher recall and F1 scores, highlighting their robustness and effectiveness in handling imbalanced data. Ensemble models, particularly Bagging and Stacking, demonstrated superior performance, achieving nearly 0.93 in Accuracy, 0.95 in Precision, 0.94 in Recall, and 0.94 in F1 metrics in follow-up conditions, significantly outperforming single models. Ensemble models based on radiomics generated from combining Initial and follow-up scans can be used to predict multilabel 90-day stroke outcomes with reduced subjectivity and user burden.

A Bacterial Platform for Studying Ubiquitination Cascades Anchored by SCF-Type E3 Ubiquitin Ligases.

Ubiquitination is one of the most important post-translational modifications in eukaryotes. The ubiquitination cascade includes ubiquitin-activating enzymes (E1), ubiquitin-conjugating enzymes (E2), and ubiquitin ligases (E3). The E3 ligases, responsible for substrate recognition, are the most abundant and varied proteins in the cascade and the most studied. SKP1-CUL1-F-Box (SCF)-type E3 ubiquitin ligases are multi-subunit RING (Really Interesting New Gene) E3 ubiquitin ligases, composed of CUL1 (Cullin 1), RBX1 (RING BOX 1), SKP1 (S-phase Kinase-associated Protein 1), and F-box proteins. In vitro ubiquitination assays, used for studying the specific recognition of substrate proteins by E3 ubiquitin ligases, require the purification of all components involved in the cascade, and for assays with SCF-type E3 ligases, additional proteins (several SCF complex subunits). Here, the Duet expression system was used to co-express E1, E2, ubiquitin, ubiquitylation target (substrate), and the four subunits of a SCF-type E3 ligase in E. coli. When these proteins co-exist in bacterial cells, ubiquitination occurs and can be detected by Western Blot. The effectiveness of this bacterial system for detecting ubiquitination cascade activity was demonstrated by replicating both AtSCFTIR1-mediated and human SCFFBXO28-mediated ubiquitylation in bacteria. This system provides a basic but adaptable platform for the study of SCF-type E3 ubiquitin ligases.

Research progress and mitigation strategies for pod shattering resistance in rapeseed.

Background: Mature rapeseed pods typically shatter when harvested, resulting in approximately 8-12% yield loss. Adverse weather conditions and mechanized harvesting can diminish pod yield by up to 50%, primarily owing to delays in harvesting and mechanical collisions. The pod shatter resistance index (PSRI) assesses pod damage. Recent research focused on comparing pod shatter resistance among varieties, evaluating methods, and studying gene knockout mechanisms. However, there remains a pressing need to broaden the scope of research. In particular, it is essential to recognize that pod shatter, a complex trait, influenced by genetics, environment, agronomic practices, and harvest techniques. Future studies should integrate these factors to develop comprehensive strategies to mitigate pod shatter, enhancing rapeseed yields and agricultural mechanization. This review explores factors affecting pod shatter resistance and strategies to improve it. Methodology: Scoping literature review that adhered to the methodological framework for systematic reviews was performed using search engines such as Google Scholar, Web of Science, and the Chinese National Knowledge Infrastructure. This review aimed to identify pertinent articles, which were subsequently subjected to thorough screening and evaluation. The protocol for this literature review involved the following key steps: definition of research questions, development of a search strategy, development of data extraction strategy, synthesis of the extracted data, and organization and analysis of the extracted data. Results: The review presents strategies for enhancing rapeseed yield during mechanized harvesting, focusing on four key areas: (i) selecting and breeding shatter-resistant varieties using DNA markers to establish a robust germplasm resource; (ii) optimizing cultivation technologies and agronomic measures to elicit favorable interactions between compact plant-type genotypes and the environment, thereby facilitating nutrient-related regulatory mechanisms of rapeseed pods to improve pod dry weight and resistance; (iii) innovating combine header design and structure to better suit rapeseed harvesting; and (iv) providing training for operators to enhance their harvesting skills. These comprehensive measures aim to minimize yield loss, increase production efficiency. Conclusion: To effectively reduce yield loss during mechanized harvesting of rapeseed, it is crucial to enhance resistance to pod shattering by addressing both internal physiological factors and external environmental conditions. This requires a holistic approach that includes genetic improvements, optimization of ecological conditions, careful cultivation management, and precise harvesting timing, along with ongoing research into traits related to machine harvesting to boost production efficiency and sustainability.

The levels of systemic inflammatory markers exhibit a positive correlation with the occurrence of heart failure: a cross-sectional study from NHANES.

Background: We conducted a large-scale epidemiological analysis to investigate the associations between systemic inflammation markers and heart failure (HF). Our aim is to identify potential biomarkers for early detection of HF. Methods: A cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey. We investigated the associations between five systemic inflammation markers (neutrophil to lymphocyte ratio [NLR], platelet to lymphocyte ratio [PLR], systemic immune inflammation index [SII], system inflammation response index [SIRI], and aggregate index of systemic inflammation [AISI]) and the risk of HF. Results: The prevalence rates of HF exhibited a gradual increase across increasing logNLR, logPLR, logSII, logSIRI, and logAISI tertiles. Compared to those in the highest tertiles of logNLR, logSII, logSIRI, and logAISI had a 1.579-fold, 1.341-fold, 1.956-fold, and 1.499-fold increased risk of HF compared to those in the lowest tertile respectively. Conversely, there was no significant correlation between logPLR and HF risk among subjects in the highest tertile. The restricted cubic splines (RCS) analysis revealed a non-linear relationship between the elevation of systemic inflammation markers and HF prevalence. Specifically, a per standard deviation increase in any of these variables is associated with a respective 45%, 29%, 28%, 44% and 29% increase in HF prevalence. The receiver operating characteristic (ROC) analysis demonstrated favorable sensitivity and specificity of these systemic inflammation markers in detecting the presence of HF. Conclusion: Our cross-sectional study demonstrates significant positive correlations between the NLR, PLR, SII, SIRI, and AISI with the incidence of HF.

The impact of 3 different dietary interventions on overweight or obese adults: A network meta-analysis.

OBJECTIVE: This network meta-analysis aims to investigate and compare the effectiveness of 3 dietary interventions - Mediterranean, ketogenic, and low-fat diet - on overweight and obese adults, with a comparison to traditional low-calorie diet. METHODS: A systematic review was conducted in both Chinese and English databases, including the China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science and Technology Journal Database (VIP), SinoMed, PubMed, Web of Science, Cochrane Library and Embase to identify relevant randomized controlled trials (RCTs) up to January 31, 2024. Two researchers independently screened and extracted data from the identified literature. The quality of these studies was assessed using the Cochrane bias risk assessment tool. A random-effects network meta-analysis was performed using Review Manager 5.4.1 and Stata 16.0 software. RESULTS: A total of 17 randomized controlled trials involving 5802 subjects were included in this study. The network meta-analysis revealed a descending order of effectiveness for reducing body weight (BW), body mass index (BMI), and waist circumference (WC): ketogenic diet > low-fat diet > low-calorie diet > Mediterranean diet. CONCLUSIONS: The ketogenic diet was identified as the most effective intervention for reducing BW, BMI, and WC in the studied dietary comparisons. It consistently showed superior outcomes, ranking highest in effectiveness among the 4 evaluated dietary approaches. Nevertheless, additional high-quality randomized controlled trials are necessary to validate these findings.

Expression and clinical significance of SYNE3 in non-small cell lung cancer.

OBJECTIVE: To detect the expression of Spectrin Repeat Containing Nuclear Envelope Family Member 3 (SYNE3) and Cluster of Differentiation 34 (CD34) in non-small cell lung cancer (NSCLC). It also aimed to explore the relationship between SYNE3 and NSCLC angiogenesis and clinicopathologic features to identify new biomarkers for NSCLC. METHODS: Forty-five NSCLC stage IA-IVB tissue specimens from patients diagnosed at Bazhong Central Hospital were collected from January to September 2022, along with 45 para-cancerous normal lung tissues as controls. None of the NSCLC patients had received anti-tumor therapies, including radiotherapy, chemotherapy, targeted therapy, immunotherapy, or traditional Chinese medicine. All specimens were stained for SYNE3 and CD34 using the Streptavidin-Peroxidase (SP) method. The expression levels of SYNE3 and CD34 in NSCLC tissues and para-cancerous tissues were detected, and a correlation analysis between SYNE3 and clinicopathological features was performed. The number of CD34-labeled microvessels was counted using the Microvessel density (MVD) method. The relationship between SYNE3 and NSCLC angiogenesis was examined through the correlation between CD34-MVD and NSCLC clinicopathologic features. RESULTS: The expression of SYNE3 in NSCLC was significantly lower than that in para-cancerous normal lung tissues, while the expression of CD34 in NSCLC was significantly higher than in para-cancerous normal lung tissues (P=0.037). SYNE3 expression in NSCLC was negatively correlated with tumor diameter and was lower in male patients with a smoking history compared to female patients without a smoking history. CD34 expression was positively correlated with Tumor, Node, Metastasis staging and lymph node metastasis. There was a significant correlation between the expression of SYNE3 and CD34 in NSCLC (r=0.450, P=0.000). CONCLUSION: SYNE3 was lowly expressed and negatively correlated with tumor size in NSCLC, whereas CD34 was highly expressed and positively correlated with TNM stage and lymph node metastasis. The significant correlation between the expressions of SYNE3 and CD34 suggests that SYNE3 may play a key role in NSCLC angiogenesis and progression.

Carrier-Free Biomimetic Organic Nanoparticles with Super-High Drug Loading for Targeted NIR-II Excitable Triple-Modal Bioimaging and Phototheranostics.

Multimodal near-infrared II (NIR-II) theranostics combined with nanotechnology have emerged as promising treatments for cancer due to their noninvasive and high spatiotemporal nature. Traditional NIR-II theranostics typically comprise useless and massive inert carriers, resulting in low drug loading capacity, reduced therapeutic effects, and potential biotoxicity. To overcome these limitations, this work reports carrier-free NIR-II theranostics simultaneously with high drug loading capacity and multimodal NIR-II imaging capabilities for cancer phototheranostics in the NIR-II window. Carrier-free BTA nanoparticles (NPs) are prepared by self-assembling the NIR-II responsive conjugated oligomer BTA without adding coating agents; these NPs exhibited 100% drug loading and high-performance NIR-II theranostic capabilities. Cancer cell membranes are camouflaged on carrier-free BTA NPs to provide homologous targeting ability, enhanced stability, and 77.8% drug loading. Both in vitro and in vivo studies have indicated that biomimetic NPs provide efficient triple-modal guidance for NIR-II fluorescence, photoacoustic, and photothermal imaging and complete tumor elimination via photothermal therapy (PTT). Additionally, theranostics-based treatments with good biosecurity are demonstrated. This study contributes a new strategy for the design of high-drug-loading NIR-II theranostics and further promotes the clinical translation of theranostic agents.

HIF1α Counteracts TGFß1-Driven TSP1 Expression in Endothelial Cells to Stimulate Angiogenesis in the Hypoxic Tumor Microenvironment.

Emerging evidence suggests that transforming growth factor ß1 (TGFß1) can inhibit angiogenesis, contradicting the coexistence of active angiogenesis and high abundance of TGFß1 in the tumor microenvironment. Here, we investigated how tumors overcome the anti-angiogenic effect of TGFß1. TGFß1 treatment suppressed physiological angiogenesis in chick chorioallantoic membrane and zebrafish models but did not affect angiogenesis in mouse hepatoma xenografts. The suppressive effect of TGFß1 on angiogenesis was recovered in mouse xenografts by a hypoxia-inducible factor 1α (HIF1α) inhibitor. In contrast, a HIF1α stabilizer abrogated angiogenesis in zebrafish, indicating that hypoxia may attenuate the anti-angiogenic role of TGFß1. Under normoxic conditions, TGFß1 inhibited angiogenesis by upregulating anti-angiogenic factor thrombospondin 1 (TSP1) in endothelial cells (ECs) via TGFß type I receptor (TGFßR1)-SMAD2/3 signaling. In a hypoxic microenvironment, HIF1α induced microRNA-145 (miR145) expression; miR145 abolished the inhibitory effect of TGFß1 on angiogenesis by binding and repressing SMAD2/3 expression and subsequently reducing TSP1 levels in ECs. Primary ECs isolated from human hepatocellular carcinoma (HCC) displayed increased miR145 and decreased SMAD3 and TSP1 compared to ECs from adjacent non-tumor livers. The reduced SMAD3 or TSP1 in ECs was associated with increased angiogenesis in HCC tissues. Collectively, this study identified that TGFß1-TGFßR1-SMAD2/3-TSP1 signaling in ECs inhibits angiogenesis. This inhibition can be circumvented by a hypoxia-HIF1α-miR145 axis, elucidating a mechanism by which hypoxia promotes angiogenesis.

Optimizing nitrogen fertilizer for improved root growth, nitrogen utilization, and yield of cotton under mulched drip irrigation in southern Xinjiang, China.

The root system plays a crucial role in water and nutrient absorption, making it a significant factor affected by nitrogen (N) availability in the soil. However, the intricate dynamics and distribution patterns of cotton (Gossypium hirsutum L.) root density and N nutrient under varying N supplies in Southern Xinjiang, China, have not been thoroughly understood. A two-year experiment (2021 and 2022) was conducted to determine the effects of five N rates (0, 150, 225, 300, and 450 kg N ha-1) on the root system, shoot growth, N uptake and distribution, and cotton yield. Compared to the N0 treatment (0 kg N ha-1), the application of N fertilizer at a rate of 300 kg N ha-1 resulted in consistent and higher seed cotton yields of 5875 kg ha-1 and 6815 kg ha-1 in 2021 and 2022, respectively. This N fertilization also led to a significant improvement in dry matter weight and N uptake by 32.4% and 53.7%, respectively. Furthermore, applying N fertilizer at a rate of 225 kg N ha-1 significantly increased root length density (RLD), root surface density (RSD), and root volume density (RVD) by 49.6-113.3%, 29.1-95.1%, and 42.2-64.4%, respectively, compared to the treatment without N fertilization (0 kg N ha-1). Notably, the roots in the 0-20 cm soil layers exhibited a stronger response to N fertilization compared to the roots distributed in the 20-40 cm soil layers. The root morphology parameters (RLD, RSD, and RVD) at specific soil depths (0-10 cm in the seedling stage, 10-25 cm in the bud stage, and 20-40 cm in the peak boll stage) were significantly associated with N uptake and seed cotton yield. Optimizing nitrogen fertilizer supply within the range of 225-300 kg N ha-1 can enhance root foraging, thereby promoting the interaction between roots and shoots and ultimately improving cotton production in arid areas.

The effect of lateral thrust on the progressive slope failure under excavation and rainfall conditions.

Large landslides can involve the multiple failures of regional slopes. To understand the effect of lateral thrust caused by the failure of one slope on its surroundings, the failures of two adjacent highway slopes in Guangdong Province, China, were investigated in detail. The interactive failure processes and landslide morphological characteristics of the two slopes were first analyzed based on the on-site investigation. Then, a plane mechanical model of a large-scale slope was established to evaluate the significant influence of the lateral thrust generated by the west slope acting on the east excavated slope. Furthermore, the extrusion effect of the west slope was modelled under the alternate excavation disturbance and rainfall by transferring the thrust forces onto the interface elements, and the induced failure mechanism and instability mode of the east slope under lateral thrust were reproduced numerically. The results show that the compression-shear failure occurred at the middle and rear slope bodies because of the lateral thrust, which led to the formation of a thrust landslide and the final instability of the east slope.

Efficacy of non-pharmacological interventions on sleep quality in patients with cancer-related insomnia: a network meta-analysis.

Objective: Despite the widespread application of non-pharmacological therapies in treating cancer-related insomnia, a comprehensive assessment of these methods is lacking. This study aims to compare the efficacy of 11 non-pharmacological interventions for cancer-related insomnia, providing a theoretical basis for clinicians in choosing treatment methods. Methods: We searched five databases, including the Cochrane Central Register of Controlled Trials, PubMed, Embase, Wiley Library, and Web of Science, for relevant randomized controlled trials. Included studies involved patients diagnosed with cancer-related insomnia, employed non-pharmacological treatments, and reported outcomes using the PSQI and ISI. Bayesian statistical methods were used for the network meta-analysis, and statistical processing was performed using Review Manager 5.4 and Stata 14.0 software. The results were thoroughly analyzed and evaluated, and publication bias was assessed using funnel plot tests. Results: Our study included 41 randomized controlled trials, comprising 11 different non-pharmacological interventions (3,541 participants), the network analysis identifying Electroacupuncture as the most effective, with a SUCRA value of 92.2% in ISI, this was followed by Professionally administered Cognitive behavioral therapy for insomnia(PCBT-I) and Mindfulness-based cognitive therapy(MBCT), with SUCRA values of 78.4 and 64.1%, respectively. Traditional Cognitive behavioral therapy for insomnia(CBT-I) and VCBT-I showed lower efficacy with SUCRA values of 55.9 and 55.2%, respectively. Exercise interventions and control groups had the lowest efficacy, with SUCRA values of 24.0 and 16.1%. Using PSQI as the outcome measure, Massage therapy ranked highest in improving sleep quality with a SUCRA value of 92.2%, followed by Professionally administered Cognitive behavioral therapy for insomnia (PCBT-I) and Electroacupuncture. League tables indicated significant improvements in sleep outcomes for Electroacupuncture and MT compared to control groups, with Electroacupuncture (EA) showing an MD of -7.80 (95% CI: -14.45, -1.15) and MT an MD of -4.23 (CI: -8.00, -0.46). Conclusion: Considering both outcome indicators, Electroacupuncture was significantly effective in alleviating the severity of insomnia, while MT was most effective in improving sleep quality. Therefore, in the non-pharmacological interventions for cancer-related insomnia, Electroacupuncture and MT May be particularly effective choices. Future research should further explore the specific mechanisms of action of these interventions and their efficacy in different patient groups.

A bioabsorbable mechanoelectric fiber as electrical stimulation suture.

In surgical medicine, suturing is the standard treatment for large incisions, yet traditional sutures are limited in functionality. Electrical stimulation is a non-pharmacological therapy that promotes wound healing. In this context, we designed a passive and biodegradable mechanoelectric suture. The suture consists of multi-layer coaxial structure composed of (poly(lactic-co-glycolic acid), polycaprolactone) and magnesium to allow safe degradation. In addition to the excellent mechanical properties, the mechanoelectrical nature of the suture grants the generation of electric fields in response to movement and stretching. This is shown to speed up wound healing by 50% and reduce the risk of infection. This work presents an evolution of the conventional wound closure procedures, using a safe and degradable device ready to be translated into clinical practice.

Three undescribed isosteroidal alkaloids from the bulbs of Fritillaria ussuriensis maxim: Anti-inflammatory activities, docking studies and molecular dynamic.

Three undescribed isosteroidal alkaloids (1-3), along with two known ones (4, 5) were isolated from the bulbs of Fritillaria ussuriensis Maxim, their structures were established by comprehensive analyses of the 1D, 2D-NMR and HR-ESI-MS data. Meanwhile, LPS-activated RAW 264.7 macrophages were used to determine the potential anti-inflammatory activity of all the alkaloids in vitro. Among them, compounds 1 and 4 showed significant inhibitory effects against LPS-induced NO production with IC50 values of 7.79 µM and 11.22 µM, respectively. Compounds 1 and 4 were performed between molecular docking with TLR4/MD2. Based on the results of cell experiments and binding affinities, compound 1 (UG) was chosen for molecular dynamic analysis together with the TLR4/MD2 protein.

Comparison of visual acuity outcome and choroidal thickness variation of intravitreal ranibizumab injection for myopic choroidal neovascularization with or without dome-shaped macula.

BACKGROUND: To investigate the visual acuity outcome and choroid thickness (CT) change after intravitreal ranibizumab in highly myopic eyes with or without dome-shaped macula (DSM) in Chinese patients. METHODS: This retrospective, observative study included 80 treatment-naive eyes (80 patients), which received ranibizumab according to the 1+PRN protocol. The best corrective visual acuity (BCVA) and CT change were compared between eyes with or without DSM. RESULTS: There was no significant difference between eyes with or without DSM in BCVA and central macular thickness (CMT). The recurrent rate was not different between the two groups during the first year of treatment. The CT was significantly thinner in eyes with DSM than in eyes without DSM before treatment (median 40.00um versus 71.00um), at 1 month after treatment (median 31.00um versus 65.50um), and in the last follow up (median, 32.00um versus 65.00um) (p = 0.0101). Axial length (AL) was longer in eyes with DSM than those without DSM (median, 29.17 mm versus 28.10 mm) before treatment, and in the last follow up (median, 29.44 mm versus 28.20 mm) (p = 0.0055). The CT was significantly correlated with AL (p < 0.0001). CONCLUSIONS: No difference was found in visual outcome between eyes with or without DSM. The visual acuity significantly improved at 1 month after ranibizumab injection and it was recovery sooner in extrafoveal choroidal neovascularization (CNV) group than in subfoveal CNV group. The CT was thinner in eyes with DSM, which was significantly correlated with AL.

Will the Dark Triad Engender Psychopathological Symptoms or Vice Versa? A Three-Wave Random Intercept Cross-Lagged Panel Analysis.

INTRODUCTION: The Dark Triad (DT), including narcissism, Machiavellianism, and psychopathy, represents the dark side of human nature and has been related to psychopathological symptoms (e.g., depression, anxiety, and stress). However, little is known about how the two constructs are related longitudinally. To fill this gap and to clarify the directionality between them, we conducted a longitudinal study. METHODS: We measured DT traits and psychopathological symptoms in a large sample of university students (NT1 = 1815) annually for 3 years. We implemented random intercept cross-lagged panel models in analysis. RESULTS: Narcissism and psychopathological symptoms showed a reciprocal relationship at the within-person level: greater narcissism preceded a decline in psychopathological symptoms, while more severe symptoms preceded a decrease in narcissism. Within the same individual, increases in the DT, particularly psychopathy and Machiavellianism, were linked to concurrent escalations in the symptoms. Additionally, all DT traits were positively correlated with psychopathological symptoms as stable differences between individuals. CONCLUSIONS: This study constitutes an important step in clarifying the directionality between the DT and psychopathological symptoms, and advances our understanding of the interplay between these two constructs at both the between-person and within-person levels.

Association between glymphatic dysfunction and neurocognitive decline in patients with frontal lobe epilepsy.

Background: The glymphatic system is essential for the maintenance of brain homeostasis. It may be impaired in patients with epilepsy, but its association with neurocognitive function remains unknown. In this study, we aimed to elucidate the association between changes in the glymphatic system and neurocognitive function in individuals diagnosed with frontal lobe epilepsy (FLE). Methods: This retrospective case-control research engaged a group of patients with FLE and age-, sex-, and education-matched healthy volunteers. All participants were subjected to extensive neurocognitive assessments, complemented by structural and diffusion-weighted imaging. The "diffusion tensor imaging analysis along the perivascular space" (DTI-ALPS) index was computed to ascertain differences in glymphatic system function between the groups. Univariate and multivariate analyses were conducted to explore associations between DTI-ALPS, clinical characteristics in patients with FLE, and the neurocognitive test outcomes for both groups. Results: Twenty-five patients [mean age ± standard deviation (SD): 26.28±8.12 years, 10 females] with FLE and 22 healthy control (HC) participants (average age ± SD: 25.86±6.15 years, 11 females) were included. The average ALPS-index in FLE group was significantly lower than that in HC group (1.387±0.127 vs. 1.468±0.114, P=0.026). Further, significant neurocognitive difference was noted in Trail Making Test (TMT), Stroop Color and Word Test (SCWT), Digit Span Test (DST) and similarity test (ST) between the two groups. ALPS-index scores exhibited a negative correlation with disease duration in patients with FLE (r=-0.415, P=0.039), and positive correlations with the Forward Digit Span Test (FDST, r=0.399, P=0.005) and Similarity Test (ST, r=0.395, P=0.006) in both groups. After adjusting for potential confounders, DTI-ALPS maintained a significant independent association with FDST and ST. Conclusions: The findings of the current study suggest a possible association between impairment in glymphatic function and FLE. Furthermore, results indicate that glymphatic dysfunction, as assessed via DTI-ALPS index, appears to be related to neurocognitive decline in FLE.

Transplantation of chemically induced pluripotent stem-cell-derived islets under abdominal anterior rectus sheath in a type 1 diabetes patient.

We report the 1-year results from one patient as the preliminary analysis of a first-in-human phase I clinical trial (ChiCTR2300072200) assessing the feasibility of autologous transplantation of chemically induced pluripotent stem-cell-derived islets (CiPSC islets) beneath the abdominal anterior rectus sheath for type 1 diabetes treatment. The patient achieved sustained insulin independence starting 75 days post-transplantation. The patient's time-in-target glycemic range increased from a baseline value of 43.18% to 96.21% by month 4 post-transplantation, accompanied by a decrease in glycated hemoglobin, an indicator of long-term systemic glucose levels at a non-diabetic level. Thereafter, the patient presented a state of stable glycemic control, with time-in-target glycemic range at >98% and glycated hemoglobin at around 5%. At 1 year, the clinical data met all study endpoints with no indication of transplant-related abnormalities. Promising results from this patient suggest that further clinical studies assessing CiPSC-islet transplantation in type 1 diabetes are warranted.

Individualized responses to acupuncture in premature ovarian insufficiency: A study protocol for a nested case-control trial with transcriptome analysis.

Background: Premature ovarian insufficiency (POI), a modifiable cause of infertility with substantial implications for women's well-being, prompts the exploration of efficacious adjunctive treatments. Acupuncture emerges as a promising therapeutic avenue; however, the nuanced effects of acupuncture in POI warrant more comprehensive investigation. The intricate mechanisms dictating individualized responses remain elusive. This trial seeks to assess the effectiveness of acupuncture as an adjunctive treatment for POI, concurrently delving into the impact of transcriptome analysis on peripheral blood to unravel the underpinnings of these individual variations. The overarching objective is to enrich our comprehension of acupuncture's therapeutic potential in the context of POI, with a view to advancing holistic patient care. Methods/design: Constituting an open-label, nested case-control study, this research endeavors to enroll 108 women diagnosed with POI. Participants will be randomly assigned in a 1:1 ratio to either the study group or the control group, each comprising 54 subjects. Ten patients from each group meeting specific criteria will partake in transcriptome analysis. An additional 10 subjects meeting the study criteria will form a healthy control group. The study group will exclusively undergo acupuncture treatment, while the control group will solely receive Fenmutong. Acupuncture sessions, administered thrice weekly across three menstrual cycles from the fifth day of menstruation, constitute the intervention. Primary outcome measurement rests on Follicle-Stimulating Hormone (FSH) levels, supplemented by secondary assessments encompassing biometric features, hormone biomarkers, anxiety and depression scores, and transcriptome analysis. Baseline measurements precede intervention, with post-intervention evaluations following. The study endeavors to discern specific genes linked to individualized responses to acupuncture. Data analysis, employing SPSS 25.0 software, incorporates a meticulous examination of peripheral blood samples for transcriptome analysis.
