Objective To explore the role and potential mechanisms of plasma-activated solution(PAS)in alleviating dextran sulfate sodium salt(DSS)-induced ulcerative colitis.Methods We constructed a DSS-induced ulcerative colitis mouse model and evaluated the effect of PAS in vivo by observing mouse weight,calculating disease activity indexes,detecting inflammatory factors and oxidative stress indicators through ELISA.We also evaluated the effect of PAS on colon cell proliferation and migration ability through clone formation experiments,scratch experiments,and used Western blotting to determine the expression levels of proliferation-related proteins.Results PAS significantly reversed DSS-induced weight loss and increased disease activity indexes in mice(P<0.05).The serum inflammatory cytokine levels(TNF-α,IL-6 and IL-1β)in PAS group were significantly reduced compared to those in DSS group(P<0.05).PAS treatment could improve the imbalance of colonic redox homeostasis including changes of malondialdehyde,catalase and superoxide dismutase caused by DSS(P<0.05).After the use of endothelial nitric oxide synthase inhibitors,changes in various indicators caused by in vivo PAS disappeared(P<0.001).The clone formation ability of colon cells was stronger in the group treated with PAS,and the expression of proliferation-related proteins increased.Cell scratch experiments suggested that intervention with PAS could reverse the decrease in cell migration ability caused by lipopolysaccharide(P<0.001).After the application of endothelial nitric oxide synthase inhibitors,the pro-proliferative and migratory effects of PAS disappeared(P<0.05).Conclusion PAS alleviate DSS-induced colitis in mice and promote colonic epithelial cell repair through the eNOS pathway.

Objective This study aimed to explore the clinical and etiological characteristics of bloodstream infections in diabetic patients with different levels of glycosylated hemoglobin(HbA1c)for improving empirical diagnosis and treatment in clinical practice.Methods A retrospective study was conducted for diabetic patients with bloodstream infections who were admitted to Sichuan Mental Health Center from 2017 to 2023.Patients were assigned to one of the three groups based on HbA1c levels:low level(HbA1c<7.0%),medium level(7.0%≤HbA1c<9.0%),high level(HbA1c≥9.0%).The clinical data,pathogen distribution,and antimicrobial resistance were analyzed and compared between groups.Results A total of 426 diabetic patients with bloodstream infection were included.The proportion of community-acquired bloodstream infection,acidosis,and liver abscess in the high level HbA1c group were significantly higher than those in the medium and low level HbA1c groups.Overall,452 strains of nonduplicate pathogenic bacteria were isolated,the most common of which were Escherichia coli(47.1%),Klebsiella pneumoniae(23.0%),and Staphylococcus aureus(5.8%).The pathogens of bloodstream infections varied with different HbA1c levels.The proportion of K.pneumoniae in the high-level HbA1c group(30.7%)was significantly higher than that in the low-level HbA1c group(15.1%)and medium level HbA1c group(16.0%).More than 50%of E.coli isolates were resistant to piperacillin,cefazolin,and ampicillin,while lower than 10%of the isolates were resistant to cefoxitin and minocycline,and lower than 1%of the isolates were resistant to piperacillin-tazobactam,meropenem,imipenem,and amikacin.The E.coli strains isolated from hospital-acquired infections showed slightly higher resistance rates to penicillin,cephalosporins,aminoglycosides,and fluoroquinolones than the strains isolated from community-acquired infections.K.pneumoniae strains showed low resistance rates(<30%)to the commonly used antibiotics.However,the strains isolated from hospital-acquired infections were significantly more resistant to cephalosporins,carbapenems,and aminoglycosides than the strains isolated from community-acquired infections.Conclusions E.coli,K.pneumoniae and S.aureus were the common pathogens of bloodstream infections in diabetic patients.Poor HbA1c control was associated with K.pneumoniae bloodstream infection,especially those originated from liver abscess.The antibiotic-resistant E.coli and K.pneumoniae strains were prevalent in hospital-acquired bloodstream infections in diabetic patients.Antimicrobial resistance surveillance should be strengthened for this patient population.

Obesity and metabolic dysfunction-associated steatotic liver disease (MASLD) are linked to numerous chronic conditions, including cardiovascular disease, atherosclerosis, chronic kidney disease, and type II diabetes. Previous research identified the natural flavonoid diosmin, derived from Chrysanthemum morifolium, as a regulator of glucose metabolism. However, its effects on lipid metabolism and underlying mechanisms remained unexplored. The AMP-activated protein kinase (AMPK) pathway serves a critical function in glucose and lipid metabolism. The relationship between diosmin and the AMPK pathway has not been previously documented. This investigation examined diosmin's capacity to reduce lipid content through AMPK pathway activation in hepatoblastoma cell line G2 (HepG2) and 3T3-L1 cells. The study revealed that diosmin inhibits lipogenesis, indicating its potential as an anti-obesity agent in obese mice. Moreover, diosmin demonstrated effective MASLD alleviation in vivo. These findings suggest that diosmin may represent a promising therapeutic candidate for treating obesity and MASLD.

The fungal bioluminescence pathway (FBP) catalyzes the oxidation of endogenous caffeic acid to produce green bioluminescence through an enzymatic cascade. Genetic engineering of FBP into plants creates autoluminescent specimens that circumvent the substrate limitations of conventional reporter systems. These transgenic plants serve dual functions as aesthetic displays and versatile biosensing platforms, enabling applications in real-time gene expression monitoring, continuous environmental surveillance, and non-invasive bioimaging, offering novel opportunities for horticultural production, environmental conservation, and bioengineering applications. This review synthesizes current advances in plant FBP engineering and explores how machine learning approaches can optimize autoluminescent phenotypes, thereby accelerating innovation in agricultural biotechnology, environmental sensing, and synthetic biology applications.

Objective To compare the 12-month efficacy and safety of N-butyl cyanoacrylate (NBCA) versus radiofrequency ablation (RFA) in treating great saphenous vein (GSV) insufficiency. Methods A total of 155 patients with GSV insufficiency from five centers were randomly allocated to the NBCA group or RFA group. Postoperative efficacy and safety outcomes were evaluated. Results Immediate postoperative closure rates of the GSV trunk were 100% in both groups. The closure rates of NBCA and RFA group were 98.6% and 98.5% at 3 months, 97.1% and 98.5% at 6 months, 98.1% and 95.9% at 12 months, with no statistically significant differences (P>0.05). After treatment, CEAP classification improved significantly from baseline in both groups. In terms of safety, 1 case of phlebitis, 1 case of ablation-related thrombus extension (ARTE) and 2 cases of calf muscle venous thrombosis(CMVT) occurred in the NBCA group, while 2 cases of limb numbness, 1 case of persistent thigh pain and 2 cases of CMVT in the RFA group. All reported serious adverse events in both groups were assessed as unrelated to the medical device or the trial procedure. Conclusions NBCA demonstrates non-inferior efficacy and safety compared to RFA for treating GSV insufficiency over 12 months.

Basket trial, as an innovative clinical trial design concept, marks the transformation of medical research from the traditional large-scale and single-disease treatment to the precise and individualized treatment. By gradually incorporating the Bayesian method during development, the trial design becomes more scientific and reasonable and increases its efficiency. The fundamental principle of the Bayesian method is the utilization of prior knowledge in conjunction with new observational data to dynamically update the posterior probability. This flexibility enhances the basket trial's capacity to effectively adapt to variations during the research process. Consequently, it enables researchers to dynamically adjust research strategies based on accumulated data and improve the predictive accuracy regarding treatment responses. In addition, the design concept of the basket trial aligns with the traditional Chinese medicine(TCM) principle of "homotherapy for heteropathy". The principle of "homotherapy for heteropathy" emphasizes that under certain conditions, different diseases may have the same treatment. Similarly, basket trials allow using a uniform trial design across multiple diseases, offering enhanced operational and significant practical value in the realm of TCM, particularly within the context of syndrome-based disease research. By introducing basket trials, the design of TCM clinical studies will be more scientific and yield higher-quality evidence. This study systematically categorized various Bayesian methods and models utilized in basket trials, evaluated their strengths and weaknesses, and identified their appropriate application contexts, so as to offer a practical guide for designing basket trials in the realm of TCM.
