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.

OBJECTIVES: To fabricate an injectable composite microsphere hydrogel reinforced with silk fibroin/hyaluronic acid microspheres, achieving synergistic enhance-ment of mechanical robustness and biofunctionality. METHODS: Methacrylated hyaluronic acid (HAMA) and thiolated silk fibroin (TSF) were synthesized. Monodisperse microspheres generated via microfluidics were UV-cured (420 nm) through thiol-ene click reaction. These microspheres were embedded in a TSF/HAMA matrix to form photo-cured composites. The grafting rate of TSF and HAMA was characterized by H1-NMR; particle size distribution of microsphere hydrogels in soybean oil was observed by optical microscopy; gel point of composite microsphere hydrogels was determined by advanced extensional rheometer; microscopic morphology of microsphere hydrogels was observed by scanning electron microscopy; elemental distribution of microsphere hydrogels was detected by X-ray energy dispersive spectroscopy; tunability of composite microsphere hydrogels was observed by inverted confocal microscopy; mechanical properties of composite microsphere hydrogels were tested by compression testing; swelling ratio, degradation rate and water retention rate of composite microsphere hydrogels were measured by gravimetric method. Cytotoxicity of the composite microsphere hydrogels was determined by Calcein-AM/propidium iodide dual staining and CCK-8 assay; cell migration capability was observed by scratch assay. RESULTS: The grafting rates of HAMA and TSF was 48.03% and 17.99%, respectively. Microsphere hydrogels with particle sizes of (43.3±1.2), (78.1±3.0), and (130.8±1.9) μm were prepared. The gel time of the composite microsphere hydrogels was 48-115s. The laser confocal imaging confirmed dynamic regulation characteristics of the composite microsphere hydrogels. The compressive strength of the composite microsphere hydrogels reached 22.7 kPa and maintained structural integrity at 40% strain after 20 compression cycles. The composite microsphere hydrogels exhibited differential deswelling behaviors in simulated physiological environments, and reducing microsphere particle size could significantly enhance its stability under moist conditions. The degradation rate of the composite microsphere hydrogels was (49.1±0.9)% after 200 h, and water retention rate was maintained at 40%-60% after 96 h. Biocompatibility assays confirmed >95% cell viability and unimpaired cell migration abilities. CONCLUSIONS The TSF/HAMA composite microsphere hydrogel developed in this study has characteristics of rapid fabrication, adjustable mechanical properties, enhanced environmental stability and excellent biocom-patibility, thus providing a new material solution for tissue repair and regenerative medicine.

Interfering hepatitis B virus (HBV) capsid assembly holds promise as a therapeutic approach for chronic hepatitis B (CHB). Novel anti-HBV agents are urgently needed to overcome drug resistance challenges, with targeted protein degradation (TPD) emerging as a hopeful strategy. Herein, we report the first degradation of HBV core protein (HBC), a multifunctional structural protein, using small-molecule degraders developed by hydrophobic tagging (HyT) technology. Structure-activity relationship (SAR) analysis identified compound HyT-S7, featuring an adamantyl group, exhibiting potent inhibitory activity (EC₅₀ = 0.46 μmol/L, HepAD38 cells) and degradation ability (DC₅₀ = 3.02 ± 0.54 μmol/L) in a dose- and time-dependent manner. Mechanistic studies demonstrated that the autophagy-lysosome pathway was a potential driver of HyT-S7-induced HBC degradation. Remarkably, HyT-S7 effectively degraded 11 drug-resistant mutants, including highly resistant strains P25G and T33N, to Phase III drug GLS4. Furthermore, cellular thermal shift assay, surface plasmon resonance assay, and molecular dynamics simulations revealed the precise mode of HyT-S7 binding to HBC with the adamantyl group potentially mimicking protein misfolding to facilitate HBC degradation. This first proof-of-concept study highlights the potential of HyT-mediated TPD in HBC as a promising avenue for discovering novel HBV and other antiviral agents with favorable drug resistance profiles.

Natural products (NPs) are an important source of new drugs for the treatment of stroke. Identifying cellular targets for bioactive molecules is a major challenge and critical issue in the development of new drugs for stroke. Small-molecule probes play a unique role in target discovery. However, drawbacks to these probes include non-specificity, unstable activity, and difficulty in synthesis. Small-molecule probes based on NPs at least partially compensate for these shortcomings. NPs feature rich chemical and structural diversity, biocompatibility, and unique biological activities. These features could be exploited to provide new ideas and tools for target discovery. Small-molecule probes based on NPs provide a precise and direct search for interacting protein targets of NPs-active small molecules. This review explores the properties of small-molecule probes based on NPs and their applications in mechanistic studies of stroke and other diseases. We hope that this review will bring new perspectives to the mechanistic study of NPs-active small molecules and accelerate the translation of these ingredients into drug candidates for the treatment of stroke.

Objective:To investigate the effect of ear acupoint bean pressing on gastrointestinal motility and related hormones after laparoscopic surgery in patients with hysteromyoma,and to explore the therapeutic mechanism of ear acupoint bean pressing.Methods:Patients undergoing laparoscopic myomectomy in the Department of Gynecology of The People's Hospital Affiliated to Fujian Univer-sity of Traditional Chinese Medicine from May 2022 to December 2023 were randomly divided into an experimental group and a control group,with 57 patients in each group.The experimental group was treated with postoperative routine nursing and ear acupoint bean pressing(targeting the spleen,stomach,and sympathetic),and the control group was treated with postoperative routine nursing and sham ear acupoint bean pressing(containing no Vaccaria seed,targeting the spleen,stomach,and sympathetic).After the intervention,the time to first postoperative passing of flatus and defecation,clinical efficacy,and changes in gastrointestinal hormone levels were compared between the two groups.Results:The time to first postoperative passing of flatus[20.31(17.52,22.38)h vs.21.51(18.53,28.15)h]and defecation[35.32(31.47,39.17)h vs.38.12(33.44,42.78)h]in the experimental group was lower than that in the control group(P<0.05),and the clinical efficacy was better than that in the control group(P<0.05).There were no significant differ-ences in motilin(MTL),gastrin(GAS),somatostatin(SS),and substance P(SP)levels between the two groups before operation(P>0.05).The MTL and GAS levels were increased and the SS and SP levels were decreased after operation.The MTL[(451.52±54.33)pg/mL vs.(476.24±56.35)pg/mL]and GAS[150.50(133.93,164.52)pg/mL vs.173.44(154.45,184.63)pg/mL]levels at 24 h after operation in the experimental group were lower than those in the control group(P<0.05),and the SS[38.34(33.24,40.23)pg/mL vs.33.36(29.13,38.76)pg/mL]level at 24 h after operation was higher than that in the control group(P<0.05),with no significant change in the SP level(P>0.05).The results of repeated measures analysis of variance and generalized estimation equation showed that there were significant differences in the time effect and interaction effect of MTL(P<0.05),a significant difference in the time effect of SP(P<0.05),and significant differences in the time effect,intergroup effect,and interaction effect of GAS and SS(P<0.05).Conclusion:Ear acupoint bean pressing has significant effect on abdominal distension after laparoscopic surgery in patients with hysteromyoma,ef-fectively regulates the level of gastrointestinal motility related hormones,and promotes the recovery of gastrointestinal function.

Fractures requiring surgical intervention during pregnancy is rarely seen in clinic,and these patients need special treatment and nursing,necessitating the consideration of both maternal fracture repair and fetal safety.For patients in late pregnancy,they have higher risk of complications,such as premature birth,placental abruption,venous thromboembolism(VTE),and anesthesia-relat-ed manifestations during the perioperative period.This article reported a case of a patient at 28 weeks of gestation with medial and lateral malleolar fractures accompanied by ankle joint subluxation and summarized the successful experience of collaboration by a multidisciplinary team(MDT).In terms of nursing,personalized body position management was implemented to relieve inferior vena cava com-pression;a phased analgesic strategy combining nerve block with drugs safe for the fetus was adopted;continuous electronic fetal heart rate and uterine contraction monitoring were carried out to ensure fetal stability during surgery;VTE prevention was strengthened by combining intermittent pneumatic com-pression devices with low-molecular-weight heparin;nutritional support and psychological counseling were provided.No complications such as infection,thrombosis,or fetal distress occurred after surgery.The Patient's ankle Kofoed score reached 88 points three months after surgery,indicating good func-tional recovery.Finally,the patient delivered a healthy male infant at full term,with a good Apgar score,and both the mother and the infant were safe.The case indicates that refined perioperative nursing combined with multidisciplinary collaboration can effectively reduce risks and improve the clinical outcomes of pregnant patients with fractures.

Objective To investigate the clinical characteristics,treatment strategies,and prognostic factors of adenoid cystic carcinoma(ACC)of the external auditory canal(EAC),and to provide evidence for optimizing surgical extent and adjuvant therapy.Methods A retrospective cohort study was conducted on 58 patients with pathologically confirmed ACC of the EAC treated in Department of Otorhinolaryngology Head and Neck Surgery,Beijing Tongren Hospital,Capital Medical University,between January 2001 and December 2021.All patients underwent surgical treatment,with some receiving adjuvant radiotherapy.The primary outcome was local recurrence,while secondary outcomes included overall survival(OS)and local recurrence-free survival(LRFS).Survival analysis was performed by the Kaplan-Meier method,and Cox regression models were used to identify risk factors for recurrence.Results The median follow-up time for the entire cohort was 6.27(3.25,11.30)years.The 1-year,3-year,and 5-year OS rates were 96.55％,91.37％,and 89.66％.43.10％of cases were classified as T4 stage at diagnosis,indicating advanced local progression.Local recurrence occurred in 23 patients(39.66％),and distant metastasis was observed in 28 patients(48.28％),with pulmonary metastasis accounting for 92.86％of cases.Multivariate analysis revealed that the solid histological pattern(HR=2.729,95％CI:1.025-7.226,P=0.044)and perineural invasion(PNI)(HR=9.891,95％CI:3.525-27.752,P＜0.01)were independent risk factors for local recurrence.Conclusion ACC of the EAC is characterized by a high propensity for local recurrence and distant metastasis.The solid histological pattern and perineural invasion are critical prognostic determinants.Multimodal therapy(surgery combined with adjuvant radiotherapy)may improve clinical outcomes,and early diagnosis and intervention are pivotal for enhancing survival rates.

Objective To assess the effectiveness of the Gasdermin D C-terminal fragment(GSDMD-CT)as a novel plasma biomarker for the clinical diagnosis of sepsis.Methods Between July 2021 and November 2024,245 patients from Tangshan Gongren Hospital were enrolled in this study.In accordance with the diagnostic criteria for sepsis and the systemic inflammatory response syndrome(SIRS),patient samples were classified into the sepsis group and the SIRS group.Meanwhile,healthy individuals were selected as the healthy control(HC)group.Sepsis patients were further categorized into the Gram-positive bacterial group,the Gram-negative bacterial group,and the fungal group based on the type of pathogen infection.The levels of GSDMD-CT,C-reactive protein(CRP),and procalcitonin(PCT)were measured in all subjects.Nonparametric tests were employed to compare the differences in various indices among different groups.The diagnostic value of GSDMD-CT in sepsis was evalu-ated by constructing the receiver operating characteristic(ROC)curve.Spearman's correlation analysis was used to examine the relationships among GSDMD-CT,CRP,and PCT.Results The plasma GSDMD-CT levels in the sepsis group 23.02(16.71,33.01)pg/mL and in the SIRS group 16.52(11.26,22.22)pg/mL were significantly higher than those in the healthy control group 7.02(4.42,11.43)pg/mL(U=-10.175,-7.890,P<0.001).Moreover,the plasma GSDMD-CT levels in the sepsis group were significantly higher than those in the SIRS group(U=-2.941,P<0.05).In the Gram-positive bacterial group,the Gram-negative bacterial group,and the fungal group,the GSDMD-CT levels were 23.01(17.16,27.51)pg/mL,23.41(16.78,35.50)pg/mL,and 16.29(14.53,56.27)pg/mL,respectively.When compared with the healthy control group,the GSDMD-CT levels in these three groups were all significantly higher(P<0.05).However,there were no significant differences in GSDMD-CT levels among these three groups(P>0.05).The area under the curve(AUC)of plasma GSDMD-CT for diagnosing sepsis was 0.881(95%confidence interval:0.833～0.929),with a Youden index(YI)of 0.695,a sensitivity of 85.0%,and a specificity of 84.5%.Spearman correlation analysis indicated a weak correlation between GSDMD-CT and C-reactive protein(CRP)(r=0.32,P<0.001)and a positive correlation between GSDMD-CT and procalci-tonin(PCT)(r=0.65,P<0.001).Conclusion GSDMD-CT exhibits significant clinical value in the diagnosis of sepsis and holds great potential as a biomarker in the diagnostic process of sepsis.

Purpose To investigate the role of tumor-associated neutrophils(TANs)in the sternness characteris-tics of breast cancer cells.Methods Flow cytometry was used to identify and validate the successful generation of TANs.Breast cancer cell lines were co-cultured with TANs-conditioned supernatant,and their sphere-forming capacity was assessed.Western blot and reverse transcription-quantitative polymerase chain reaction(RT-qPCR)were used to detect the expression of stem cell-associated markers.In breast cancer clinical specimens,immunohistochemistry(IHC)was performed to quantify TANs infiltration and the expression of sternness-related markers.Correlations be-tween TANs infiltration and sternness marker expression,as well as their associations with clinicopathological features of breast cancer patients,were analyzed.Results Flow cytometry results demonstrated a significantly higher survival rate of TANs compared to normal neutrophils(NEUs)(P＜0.05).In vitro,TANs-derived supernatant significantly en-hanced the sphere-forming capacity of breast cancer cells compared to NEU-derived supernatant(P＜0.05).RT-qPCR analysis revealed that the mRNA expression levels of sternness-related markers such as CD133 and SOX9 in tumor cells was significantly increased after TANs supernatant co-cultured with breast cancer cells(P＜0.05).The results of western blot further confirmed that the protein expression levels of CD133 and SOX9 were markedly increased in the TANs supernatant group relative to the NEU supernatant group(P＜0.01).Immunophenotypic analysis showed that the infiltration density of CD66b+TANs in breast cancer tissues was positively correlated with the expression of CD133(r=0.429,P＜0.001)and SOX9(r=0.561,P＜0.001)in tumor cells.Prognostic and clinicopathological analy-ses indicated that patients in the high CD66b+TANs infiltration group,high CD133 expression group,and high SOX9 expression group had significantly shorter progression-free survival(PFS)than those in the corresponding low-expres-sion/infiltration groups(P＜0.05).Furthermore,the infiltration density of CD66b+TANs was significantly associated with patient age,histological grade,and lymph node metastasis status(all with P＜0.05).CD133 expression was cor-related with patient age,lymph node metastasis,and progesterone receptor(PR)status(all with P＜0.05),while SOX9 expression was associated with patient age and lymph node metastasis status(all with P＜0.05).Conclusion TANs can promote the acquisition and maintenance of sternness characteristics in breast cancer cells.These findings may provide novel insights into the development of neutrophil-targeted immunotherapeutic strategies for breast cancer.
