ObjectiveTo observe the clinical efficacy of Tangshen Dihuang decoction in treating diabetic kidney disease (DKD) with liver-kidney Yin deficiency and blood stasis syndrome and its impact on gut microbiota. MethodsA randomized controlled clinical trial was conducted, in which 102 DKD patients with liver-kidney Yin deficiency and blood stasis syndrome were randomly assigned to the Tangshen Dihuang decoction group and the control group. Each group consisted of 51 cases, and the treatment period was 3 months. The primary efficacy indicators included urinary albumin-to-creatinine ratio (UACR), fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 hPBG), glycated hemoglobin (HbA1C), serum creatinine (SCr), blood urea nitrogen (BUN), angiotensinⅡ (AngⅡ), serum cystatin C (Cys-C), urinary N-acetyl-β-D-glucosaminidase (NAG), urinary β2-microglobulin (Uβ2-MB), traditional Chinese medicine (TCM) symptom scores, and gut microbiota. ResultsAfter treatment, the total response rate in the Tangshen Dihuang decoction was 87.23% (41/47), which was higher than that (69.57%, 32/46) in the control group (Z=4.30, P<0.05). After treatment, the TCM symptom scores decreased in both groups (P<0.01) and were lower in the Tangshen Dihuang decoction group than in the control group (P<0.01). After treatment, the control group showed decreases in UACR, Uβ2-MG, AngⅡ, and FBG (P<0.05) as well as 2 hPBG and HbA1C (P<0.01), and no significant differences in BUN, Cys-C, eGFR, SCr, and NAG. The Tangshen Dihuang decoction group showed increased eGFR (P<0.05), declined levels of UACR, BUN, Cys-C, Uβ2-MB, AngⅡ, FBG, 2 hPBG, NAG, and HbA1C (P<0.01), and no significant difference in SCr. The Tangshen Dihuang decoction group had lower BUN (P<0.05), Cys-C (P<0.05), AngⅡ (P<0.05), 2 hPBG (P<0.05), Uβ2-MG (P<0.01), and NAG (P<0.01) and higher eGFR level (P<0.05) than the control group. After treatment, the control group showed declines in Shannon, Observed_species, and Chao1 indices (P<0.05). The samples from both groups showed statistically significant differences in the principal coordinates analysis (PCoA) plot based on Anosim analysis (P<0.05). After treatment, the Tangshen Dihuang decoction group showed decreased relative abundance of Actinobacteria (P<0.05). Moreover, the relative abundance of Actinobacteria was significantly lower in the Tangshen Dihuang decoction group than in the control group (P<0.05). At the genus level, the control group showed decreased relative abundance of Bifidobacterium (P<0.05), and the Tangshen Dihuang decoction group presented increased relative abundance of Bifidobacterium and Blautia_A (P<0.05). After treatment, the Tangshen Dihuang decoction group had higher relative abundance of Bifidobacterium than the control group (P<0.01). ConclusionTangshen Dihuang decoction has a significant therapeutic effect on DKD patients with liver-kidney Yin deficiency and blood stasis syndrome. It can markedly relieve clinical symptoms and reduce proteinuria and postprandial blood glucose by antagonizing the local renin-angiotensin system (RAS) and alleviating gut microbiota dysbiosis.

ObjectiveTo compare the mosquito capture efficacy of the BG-trap method and the light trap method, and to explore the precisely applicable scenarios for the two monitoring approaches. MethodsFrom May to October 2024, one BG-trap and one light trap were placed at eight monitoring sites, with a distance of over 10 meters between the two traps at each site. Surveillance was performed twice monthly to compare the two surveillance methods in terms of mosquito species composition, the proportional distribution of female mosquitoes across different habitats, and seasonal fluctuations in mosquito density. ResultsThere were statistically significant differences in mosquito species composition (χ2=60.61, P<0.001) and female mosquito species composition (χ2=37.12, P<0.001) between the BG-trap method and the light trap method, with the BG-trap method capturing a higher proportion of Aedes albopictus than the light trap method. The average density of mosquitoes monitored by the BG-trap method [13.36 mosquitoes·(trap·night)-1] was higher than that monitored by the light trap method[4.70 mosquitoes·(trap·night)-1]. There was statistically significant difference (t=6.70, P<0.001) for the mosquito density between the two methods, and there was a significant positive correlation (r=0.909, P<0.001) for the mosquito density indices between the two methods. The average density of female mosquitoes monitored by the BG-trap method [8.18 mosquitoes·(trap·night)-1] was higher than that monitored by light trap method [3.36 mosquitoes·(trap·night)-1]. There was statistically significant difference (t=6.00, P<0.001) for the female mosquito density between the two methods, and there was a significant positive correlation (r=0.929, P<0.001) for the female mosquito density indices between the two methods. In the four different habitats, the constituent ratio of mosquitoes and female mosquitoes monitored by the BG-trap method in descending order were urban residential area (43.80% and 40.25%), rural farm households (35.55% and 38.60%), hospital (12.70% and 12.87%), and park (7.95% and 8.28%), while the constituent ratio of mosquitoes and female mosquitoes monitored by the light trap method in descending order were rural farm households (34.37% and 43.34%), hospital (33.26% and 30.03%), park (17.96% and 15.17%), and urban residential area (14.41% and 11.46%). In different habitats, there were statistically significant differences for mosquito composition ratios (χ2=189.64, P<0.001) and female mosquito composition ratios (χ2=109.15, P<0.001) between the two monitoring methods. ConclusionThe BG-trap method offers advantages such as simple operation, compact equipment, and high efficiency, with a higher trapping rate for Aedes albopictus compared to the light trap method. In routine monitoring, the BG-trap method can serve as a supplement to the light trap method, while for emergency monitoring of Aedes albopictus in dengue fever outbreak areas and mosquito collection efforts, the BG-trap method is more effective than the light trap method.

ObjectiveTo investigate the effects of lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) gene G501C on brain structure and cognitive function in patients with white matter hyperintensities (WMH). MethodsA total of 118 patients with WMH were enrolled. All participants underwent T1-weighted and T2-fluid-attenuated inversion recovery (T2-FLAIR) MRI to assess gray matter structure and WMH burden, and completed the mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA). Partial correlation and mediation analyses were performed to explore the impact of LOX-1 polymorphism on cognitive function. ResultsParticipants were divided into GG+GC group (n = 35) and CC group (n = 83). The GG+GC group showed lower MMSE and MoCA scores (MMSE: P=0.003; MOCA: P=0.015), as well as greater WMH burden (all P0.001), compared with the CC group. Voxel-based morphometry (VBM) analysis revealed reduced left thalamic volume in the GG+GC group, which was correlated with cognitive scores (all P0.05). Subregional thalamic analysis further showed volume reductions in the lateral, ventral, medial, and pulvinar thalamic regions (all P0.05) in the GG+GC group, all positively associated with cognitive performance (all P0.05). Mediation analyses indicated that volumes of the medial and pulvinar thalamic regions mediated the association between genotype and cognitive function (MMSE, MoCA), and that WMH volume mediated the effect on MoCA scores. ConclusionThe LOX-1 G501C polymorphism may indirectly affect cognitive function by influencing specific thalamic subregional volumes and white matter damage, suggesting a potential mediating role of thalamic structures between genetic background and cognitive impairment.

ObjectiveTo address abnormal foam formation during liquid fermentation of Trichoderma reesei(T. reesei) for cellulase production through process optimization.MethodsUsing quadruple fermentation tank, the process was optimized through four key parameters: medium composition, seed source preparation, feeding rate and feeding methodology. Different feeding strategies were evaluated, including time-sequence feeding, dissolved oxygen(DO) process value(PV)-linked feeding, and PID algorithm-controlled user defined function(UDF) feeding. The effects of coarse wheat bran supplementation and seed culture sources(plate vs. shake flask) on the fermentation process were also examined. Cellulase activity and biomass accumulation were monitored throughout the fermentation process.ResultsBoth reduced feeding rate and coarse wheat bran supplementation effectively decreased foam formation during protein expression, preventing abnormal foaming and overflow phenomena. The PID algorithm-controlled feeding strategy enhanced microbial growth, achieving a maximum biomass of 442. 9 g/L at 145 h. Shake flask-derived seed cultures demonstrated superior enzyme production compared to plate-derived seeds, maintaining higher enzyme activity levels after 66 h of fermentation. The combination of coarse wheat bran supplementation, time-sequence feeding strategy(sequence 1), and shake flask-derived seed culture promoted optimal cellulase accumulation, reaching an enzyme activity of 60. 096 U/mL at 145 h.ConclusionAn optimized fermentation process for T.reesei was developed, which effectively controls foam formation while maintaining high enzyme productivity.The findings provide new solutions for addressing foam-related issues in T. reesei liquid fermentation and offer valuable data support for scaling up cellulase production.

Objective To construct a nomogram model for prediction of constipation risk in adult patients with cardiovascular disease (CVD). Methods A total of 780 adult patients with CVD admitted to Zhongshan Hospital, Fudan University from June 15, 2025 to August 15, 2025 were prospectively enrolled and randomly divided into a training set and a validation set at a 7∶3 ratio. Risk factors for constipation were identified using the least absolute shrinkage and selection operator (LASSO) and Firth logistic regressions, and a nomogram model was subsequently constructed in the training set. Receiver operating characteristic (ROC) curve and the area under the curve (AUC) were used to evaluate the discrimination ability of the model. Calibration curve and decision curve analysis (DCA) were used to assess calibration and clinical applicability. The value of model was evaluated in the validation set. Results Among 780 adult patients with CVD, 391 patients (50.1%) developed constipation. Eleven variables were selected by LASSO regression and Firth logistic regression, and a nomogram model was constructed. The ROC curve showed that the AUCs of the model to predict constipation in adult patients with CVD in training and validation sets were 0.881 and 0.883, respectively. Calibration curves and DCA demonstrated good calibration and predictive performance of the model in training and validation sets. Conclusions The nomogram model based on LASSO-Firth logistic regression demonstrates good predictive performance and may serve as a useful tool for identifying adult patients with CVD at high risk of constipation.

OBJECTIVE To investigate the current status of informatization tools applied to antimicrobial stewardship in county hospitals in China, and to provide a reference for promoting the informatization development of antimicrobial stewardship in county hospitals.METHODS From August to September 2025, an online questionnaire survey was conducted among 1 007 county hospitals across 31 provinces(autonomous regions, and municipalities) in China. The survey focused on the application of four types of informatization tools:the real-time monitoring system for antimicrobial use, the pre-prescription review system, the irrational use warning system, and the electronic prescription evaluation system(hereinafter referred to as the “monitoring system”“review system”“warning system”“evaluation system”,respectively). Correlation analysis and binary Logistic regression analysis were employed to explore the influencing factors.RESULTS Of the county hospitals, 80.83% were equipped with at least one type of informatization tool for antimicrobial stewardship, while 19.17% had no relevant tool. Only 18.87% of the hospitals were equipped with all four types of tools. The monitoring system exhibited the highest equipped rate (70.80%), whereas the warning system was equipped in only 33.96% of the hospitals. Four types of tools are evenly and adequately deployed in the eastern region, the central and western regions have far lower deployment rates of intervention tools including review system and warning system, accompanied by prominent intra-provincial gaps. The total number of the health technicians, hospital grade, and prescription review rate of outpatient antibacterial drug were significantly and positively correlated with the deployment rates of the four informatization tools ( P <0.05). The results of the Logistic regression model fitting indicated that the model of the review system was rated “excellent” [area under the receiver operating characteristic curve (AUC)=0.81], and the model of the warning system was rated “further improvement” (AUC=0.67). The total number of health technicians was significantly positively correlated with the deployment rates of all four types of informatization tools (all P <0.05).CONCLUSIONS The informatization of antimicrobial stewardship in county hospitals in China remains in the initial stage of transitioning from “passive statistics” to “active prevention and control”, with challenges such as structural imbalance and regional disparities. In the future, differentiated support strategies should be implemented, the allocation of resources should be optimized, to enhance the level of refined antimicrobial stewardship.

Clinical trials have demonstrated that kilohertz-frequency transcutaneous spinal cord stimulation (TSCS) can be used to facilitate the recovery of sensory-motor function for patients with spinal cord injury, whereas the neural mechanism of TSCS is still undetermined so that the choice of stimulation parameters is largely dependent on the clinical experience. In this paper, a finite element model of transcutaneous spinal cord stimulation was used to calculate the electric field distribution of human spinal cord segments T 12 to L 2, whereas the activation thresholds of spinal fibers were determined by using a double-cable neuron model. Then the variation of activation thresholds was obtained by varying the carrier waveform, the interphase delay, the modulating frequency, and the modulating pulse width. Compared with the sinusoidal carrier, the usage of square carrier could significantly reduce the activation threshold of dorsal root (DR) fibers. Moreover, the variation of activation thresholds was no more than 1 V due to the varied modulating frequency and decreases with the increased modulating pulse width. For a square carrier at 10 kHz modulated by rectangular pulse with the frequency of 50 Hz and the pulse width of 1 ms, the lowest activation thresholds of DR fibers and dorsal column fibers were 27.6 V and 55.8 V, respectively. An interphase delay of 5 μs was able to reduce the activation thresholds of the DR fibers to 20.1 V. The simulation results can lay a theoretical foundation on the selection of TSCS parameters in clinical trials.

Objective To investigate the common molecular features of immunothrombosis, thus enhancing the comprehension of thrombosis triggered by immune and inflammatory responses and offering crucial insights for identifying potential diagnostic and therapeutic targets. Methods Differential gene expression analysis and functional enrichment analysis were conducted on datasets of systemic lupus erythematosus (SLE) and venous thromboembolism (VTE). The intersection of differentially expressed genes in SLE and VTE with those of neutrophil extracellular traps (NET) yielded cross-talk genes (CG) for SLE-NET and VTE-NET interaction. Further analysis included functional enrichment and protein-protein interaction (PPI) network assessments of these CG to identify hub genes. Venn diagrams and receiver operating characteristic (ROC) curve analysis were employed to pinpoint the most effective shared diagnostic CG, which were validated using a graft-versus-host disease (GVHD) dataset. Results Differential expression genes in SLE and VTE were associated with distinct biological processes, whereas SLE-NET-CG and VTE-NET-CG were implicated in pathways related to leukocyte migration, inflammatory response, and immune response. Through PPI network analysis, several hub genes were identified, with matrix metalloproteinase 9 (MMP9) and S100 calcium-binding protein A12 (S100A12) emerging as the best shared diagnostic CG for SLE (AUC: 0.936 and 0.832) and VTE (AUC: 0.719 and 0.759). Notably, MMP9 exhibited good diagnostic performance in the GVHD dataset (AUC: 0.696). Conclusion This study unveils the common molecular features of SLE, VTE, and NET, emphasizing MMP9 and S100A12 as the optimal shared diagnostic CG, thus providing valuable evidence for the diagnosis and therapeutic strategies related to immunothrombosis. Additionally, the expression of MMP9 in GVHD highlights its critical role in the risk of VTE associated with immune system disorders.

Objective:To evaluate the application potential of the bimodal ultrasound/near-infrared (NIR) composite nanoscale probe Arg-Gly-Asp (RGD)/Ag 2Te/perfluoropentane (PFP) @ mesoporous silica nanoparticles (MSN) in the diagnosis and treatment of microvascular diseases. Methods:Nanoprobes loaded with RGD, PFP and Ag 2Te were prepared by ultrasound sonication and carbodiimide method. The characterization of the nanoprobes was determined. The imaging performance, photothermal response, and target-seeking ability of the nanoprobes under NIR irradiation were verified. The biosafety of the nanoprobes was examined, and the thrombolytic ability of the nanoprobes was evaluated. The mice were observed to visualize microvessels of the abdominal wall under the NIR-Ⅱ imaging, and the microvascular visualization ability of the nanoprobes was evaluated. Results:The particle size of nanoprobes was (205.3±2.9) nm and the potential was (2.05±0.58) mV. The coupling rate of the RGD was (82.27±0.36)%, the encapsulation rate of the quantum dots was (80.80±3.26)%, and the photostability of the quantum dots was good. The fluorescence intensity was enhanced with the increase of the mass concentration of RGD/Ag 2Te/PFP@MSN, and the warming effect was more obvious. After ultrasound and NIR irradiation, the thrombolysis rate was significantly increased. RGD/Ag 2Te/PFP@MSN successfully realized NIR-Ⅱ fluorescence imaging of mice microvessels. The cytotoxicity assay and hemolysis assay showed that the probe had a good biosafety. Conclusion:The RGD/Ag 2Te/PFP@MSN nanoprobe is a potential strategy for targeted therapy of thrombotic diseases, combining dual-modality therapy of ultrasound and NIR to offer new possibilities for non-invasive and visual diagnosis and treatment of microvascular embolism.
