OBJECTIVE To evaluate the efficacy, safety and cost-effectiveness of deucravacitinib in the treatment of moderate- to-severe plaque psoriasis. METHODS Rapid health technology assessment (HTA) reports, systematic reviews (SR)/meta- analyses, and pharmacoeconomic studies on deucravacitinib for the treatment of moderate-to-severe plaque psoriasis were identified by searching PubMed, Web of Science, Embase, CNKI, Wanfang data and official HTA websites. The search time frame spanned from database inception to July 2025. After literature screening, data extraction, and quality assessment, the study results were subjected to descriptive analysis and synthesis. RESULTS A total of 14 articles were finally included, consisting of 1 HTA report, 10 SR/meta-analyses, and 3 pharmacoeconomic studies. Regarding efficacy, deucravacitinib demonstrated superior efficacy to both placebo and apremilast, with significantly higher response rates for Psoriasis Area and Severity Index 50/75/90/100, Static Physician’ s Global Assessment 0/1, and Dermatology Life Quality Index 0/1, as well as greater reduction in Psoriasis Symptoms and Signs Diary Score (P<0.05). Regarding safety, deucravacitinib was well-tolerated. Although the overall incidence of adverse events (AEs) was higher than placebo, it was not significantly different from apremilast. Moreover, the incidence of serious AEs and the rate of discontinuation due to AEs did not differ significantly from placebo (P>0.05). Regarding cost-effectiveness, deucravacitinib proved to be more cost-effective than apremilast across multiple healthcare system perspectives, including those of the United States, Japan, and China. CONCLUSIONS Deucravacitinib exhibits favorable efficacy, safety, and cost-effectiveness in the treatment of moderate-to-severe plaque psoriasis. Additional real-world studies are warranted to further refine its evaluation.

ObjectiveTo establish an animal model of atrial fibrillation(AF) that accurately reflects the phlegm-heat and blood stasis(TRYZ) pathogenesis in traditional Chinese medicine. MethodsForty SPF-grade SD rats were randomly assigned using a random number table to the following groups:the control group, the TRYZ+AF group,the AF group and the TRYZ group, with ten rats in each group. The TRYZ+AF and TRYZ groups underwent a high-fat diet combined with intraperitoneal lipopolysaccharide(LPS) injection to simulate the pathological alterations of TRYZ syndrome. Groups TRYZ+AF and AF were induced with acetylcholine-calcium chloride(Ach-CaCl2) via caudal vein injection to induce AF. The control group received no intervention and was maintained under normal conditions. The modeling period lasted 3 weeks. Electrocardiography was used to assess AF episodes and duration, echocardiography evaluated left atrial dimensions and cardiac function, fully automated biochemical analyzer measured the levels of total cholesterol(TC), triglycerides(TG), high-density lipoprotein cholesterol(HDL-C) and low-density lipoprotein cholesterol(LDL-C), hemoreometer analyzed the whole blood viscosity, plasma viscosity, and whole blood reduced viscosity, a coagulation analyzer assessed prothrombin time(PT), activated partial thromboplastin time(APTT), thrombin time(TT), and fibrinogen(FIB), enzyme-linked immunosorbent assay(ELISA) was used to determine the levels of C-reactive protein(CRP), interleukin(IL)-1β, IL-6, IL-17, tumour necrosis factor(TNF)-α, matrix metalloproteinase-9(MMP-9), galectin-3(Gal-3), Collagen Ⅰ, and α-smooth muscle actin(α-SMA). Hematoxylin-eosin(HE) staining and Masson's trichrome staining were used to analyze pathological changes in atrial myocardium, Western blot was employed to detect MMP-9, Collagen Ⅰ and α-SMA protein expression in myocardial tissue, real-time quantitative polymerase chain reaction(Real-time PCR) evaluated fibrous factor gene expression levels. Changes in the TRYZ syndrome were assessed via body weight, tongue color[red(R), green(G), and blue(B)], and rectal temperature. Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was employed to detect differential metabolites between the control group and the TRYZ+AF group. ResultsFollowing three weeks of sustained modeling, compared with the control group, rats in the TRYZ+AF and the TRYZ groups exhibited reduced body weight, dry faeces, elevated rectal temperature, dark red tongue, decreased RGB values on the tongue surface, and markedly elevated TC and LDL-C levels(P<0.05, P<0.01). The TRYZ+AF, TRYZ, and AF groups exhibited significantly decreased TT, APTT and PT, along with markedly elevated whole blood viscosity and FIB(P<0.05, P<0.01). Rats in the TRYZ+AF and AF groups exhibited AF rhythm, markedly decreased heart rate, prolonged RR intervals, enlarged left atrium, and significantly reduced ejection fraction and shortening fraction(P<0.05, P<0.01). Serum levels of CRP, IL-1β, IL-6, IL-17, TNF-α, MMP-9, Gal-3, Collagen Ⅰ, and α-SMA were elevated in rats from the TRYZ+AF, TRYZ, and AF groups compared to the control group, with the most pronounced increase observed in the TRYZ+AF group(P<0.05, P<0.01). Histopathology revealed that the collagen fiber deposition in the atrial of rats in the TRYZ+AF, TRYZ and AF groups was higher than that in the control group(P<0.05, P<0.01). Western blot and Real-time PCR results further demonstrated that the protein and mRNA expression levels of MMP-9, Collagen Ⅰ and α-SMA in the myocardial tissue of the TRYZ+AF group were higher than those in the other three groups(P<0.05, P<0.01). Metabolomic analysis revealed 173 differentially expressed metabolites in the TRYZ+AF group and the control group, primarily enriched in pathways such as glycerophospholipid metabolism and glycolysis/gluconeogenesis. ConclusionThis study successfully establishes a rat model of AF integrated with the TRYZ syndrome, demonstrating the pathological process where the interactions of phlegm, heat and stasis jointly trigger tremor, this provides a reliable experimental tool for in-depth research into the biological basis of this disease syndrome.

ObjectiveTo investigate the effect and mechanism of transplantation of human umbilical cord mesenchymal stem cell (hUC-MSC) with overexpression of the Numb gene in the treatment of cholestatic liver fibrosis (CLF). MethodsThe technique of lentiviral transfection was used to induce the overexpression of the Numb gene in hUC-MSC (hUC-MSCNumb-OE), and hUC-MSC transfected with empty vector (hUC-MSCOE-EV) was used as negative control. Bile duct ligation (BDL) was performed to establish a rat model of CLF, and then the rats were randomly divided into BDL group, hUC-MSC group, hUC-MSCOE-EV group, and hUC-MSCNumb-OE group, while a sham-operation group was also established. The rats in the intervention groups were given a single splenic injection of the corresponding cells after BDL, and samples were collected at the end of week 4. Related indicators were measured, including serum biochemistry, liver histopathology, the content of hydroxyproline (Hyp) in the liver, hepatic stellate cell activation, ductular reaction, liver regeneration, and the expression levels of key molecules in the Numb-p53 signaling axis. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the BDL group, the hUC-MSC group and the hUC-MSCOE-EV group had significant reductions in the levels of serum biochemical parameters (aspartate aminotransferase, gamma-glutamyl transpeptidase, total bile acid, total bilirubin, and direct bilirubin), liver fibrosis markers (the content of Hyp and the expression levels of alpha-smooth muscle actin, tumor necrosis factor-α, and transforming growth factor-beta 1), and ductular reaction markers (the expression levels of CK7 and CK19) (all P <0.05), and compared with the hUC-MSCOE-EV group, the hUC-MSCNumb-OE group had significantly greater improvements in the above indicators (all P <0.05). In addition, compared with the hUC-MSCOE-EV group, the hUC-MSCNumb-OE group had significant improvements in the expression levels of liver regeneration-related markers (albumin and hepatocyte nuclear factor 4α) and the molecules associated with the Numb-p53 signaling axis (Numb, pNumb, Mdm2, and p53) (all P <0.05). ConclusionOverexpression of the Numb gene can enhance the therapeutic effect of hUC-MSC on CLF, possibly by activating the Numb-PTBL-p53-HNF4α axis, promoting the hepatic differentiation of hUC-MSCs and subsequently enhancing liver regeneration.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Septic shock is the primary cause of mortality in sepsis, with its core pathophysiological mechanism being severe ischemia and hypoxia in critical units—composed of microcirculation and the mitochondria of functional cells—resulting from disruptions in blood flow and oxygen flow following a dysregulated host response. Due to the systemically convergent yet clinically heterogeneous nature of the host response, current understanding and management strategies for hemodynamics remain inconsistent, often leading to inadequate resuscitation or overtreatment. To improve the quality of care, based on a systematic review of the "blood flow-oxygen flow" theory, an expert panel emphasizes reevaluating septic shock from an integrated perspective of blood flow and oxygen flow, and has formulated the

AIM: To explore the effect of dihydroquercetin on visual function in mice with form deprivation myopia based on the NOD-like receptor thermoprotein domain-related protein 3(NLRP3)inflammasome pathway.METHODS: The C57BL/6 mice were randomly divided into control group and form deprivation myopia model group, and the form deprivation myopia model group was constructed by covering the right eye with a translucent eye patch. After successful modeling, the mice in the model group of form deprivation myopia were randomly divided into model group, low-, medium- and high-dose dihydroquercetin groups, and high-dose dihydroquercetin + NLRP3 agonist group. The diopter and axial length of mice in each group were detected. The kit was used to detect the levels of superoxide dismutase(SOD)and malondialdehyde(MDA)in retinal tissue. RT-qPCR was used to detect the mRNA expressions of NLRP3, apoptosis-associated spot-like protein(ASC), Caspase-1, IL-1β and IL-18 in retinal tissues. Western blot was used to detect the expression of NLRP3, ASC, cleaved Caspase-1, IL-1β and IL-18 proteins in retinal tissues. TUNEL staining was used to detect apoptosis in retinal tissue.RESULTS: Compared with the control group, the diopter of the mice in the model group decreased, and axial length increased, and the SOD decreased whereas MDA, NLRP3, ASC, Caspase-1, IL-1β, IL-18 increased, and the rate of apoptosis in retinal tissue increased(all P<0.05). Compared with the model group, the diopter of mice in the low-, medium- and high-dose dihydroquercetin groups increased, axial length shortened, the SOD increased, whereas MDA, NLRP3, ASC, Caspase-1, IL-1β, IL-18 decreased, and the rate of apoptosis in retinal tissue decreased(all P<0.05). Compared with the high-dose dihydroquercetin group, the high-dose dihydroquercetin+NLRP3 agonist group had reduced diopter, increased axial length, decreased SOD levels, elevated MDA, NLRP3, ASC, Caspase-1, IL-1β, and IL-18 levels, as well as increased apoptosis rate in retinal tissue(all P<0.05).CONCLUSION: Dihydroquercetin can improve visual function in mice with form deprivation myopia by inhibiting pyroptosis and oxidative stress responses, which may be related to the suppression of NLRP3 inflammasome. NLRP3 agonists can partially mitigate the effects of high-dose dihydroquercetin on form deprivation myopia in mice.

Objective:
To establish a prediction model for high-risk cardiovascular disease (CVD) among residents aged 35 to 75 years, so as to provide the basis for improving CVD prevention and control measures.
Methods:
Permanent residents aged 35 to 75 years were selected from Dongcheng District, Beijing Municipality using the stratified random sampling method from 2018 to 2023. Demographic information, lifestyle, waist circumference and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. Influencing factors for high-risk CVD among residents aged 35 to 75 years were identified using a multivariable logistic regression model, and a prediction model for high-risk CVD was established. The predictive effect was evaluated using the receiver operating characteristic (ROC) curve.
Results:
A total of 6 968 individuals were surveyed, including 2 821 males (40.49%) and 4 147 females (59.51%), and had a mean age of (59.92±9.33) years. There were 1 155 high-risk CVD population, with a detection rate of 16.58%. Multivariable logistic regression analysis showed that gender, age, smoking, central obesity, systolic blood pressure, fasting blood glucose, triglyceride and low-density lipoprotein cholesterol were influencing factors for high-risk CVD among residents aged 35 to 75 years (all P<0.05). The area under the ROC curve of the established prediction model was 0.849 (95%CI: 0.834-0.863), with a sensitivity of 0.693 and a specificity of 0.863, indicating good discrimination.
Conclusion
The model constructed by eight factors including demographic characteristics, lifestyle and blood biochemical indicators has good predictive value for high-risk CVD among residents aged 35 to 75 years.

Immobilized enzyme-based enzyme electrode biosensors, characterized by high sensitivity and efficiency, strong specificity, and compact size, demonstrate broad application prospects in life science research, disease diagnosis and monitoring, etc. Immobilization of enzyme is a critical step in determining the performance (stability, sensitivity, and reproducibility) of the biosensors. Random immobilization (physical adsorption, covalent cross-linking, etc.) can easily bring about problems, such as decreased enzyme activity and relatively unstable immobilization. Whereas, directional immobilization utilizing amino acid residue mutation, affinity peptide fusion, or nucleotide-specific binding to restrict the orientation of the enzymes provides new possibilities to solve the problems caused by random immobilization. In this paper, the principles, advantages and disadvantages and the application progress of enzyme electrode biosensors of different directional immobilization strategies for enzyme molecular sensing elements by specific amino acids (lysine, histidine, cysteine, unnatural amino acid) with functional groups introduced based on site-specific mutation, affinity peptides (gold binding peptides, carbon binding peptides, carbohydrate binding domains) fused through genetic engineering, and specific binding between nucleotides and target enzymes (proteins) were reviewed, and the application fields, advantages and limitations of various immobilized enzyme interface characterization techniques were discussed, hoping to provide theoretical and technical guidance for the creation of high-performance enzyme sensing elements and the manufacture of enzyme electrode sensors.
