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 explore and validate the potential targets of Paeoniae Radix Alba (P. Radix, Bai Shao) in protecting against chemical liver injury through network pharmacology, molecular docking technology, and in vitro cell experiments. Methods: Network pharmacology was used to identify the common potential targets of P. Radix and chemical liver injury. Molecular docking was used to fit the components, which were subsequently verified in vitro. A cell model of hepatic fibrosis was established by activating hepatic stellate cell (HSC)-LX2 cells with 10 ng/mL transforming growth factor-β1. The cells were exposed to different concentrations of total glucosides of paeony (TGP), the active substance of P. Radix, and then evaluated using the cell counting kit-8 assay, enzyme-linked immunosorbent assay, and western blot. Results: Analysis through network pharmacology revealed 13 key compounds of P. Radix, and the potential targets for preventing chemical liver injury were IL-6, AKT serine/threonine kinase 1, jun proto-oncogene, heat shock protein 90 alpha family class A member 1 (HSP90AA1), peroxisome proliferator activated receptor gamma (PPARG), PTGS2, and CASP3. Gene Ontology (GO) enrichment analysis indicated the involvement of response to drugs, membrane rafts, and peptide binding. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that the main pathways involved lipid and atherosclerosis and chemical carcinogenesis-receptor activation. Paeoniflorin and albiflorin exhibited strong affinity for HSP90AA1, PTGS2, PPARG, and CASP3. Different concentrations of TGP can inhibit the expression of COL-Ⅰ, COL-Ⅲ, IL-6, TNF-α, IL-1β, HSP-90α, and PTGS2 while increasing the expression of PPAR-γ and CASP3 in activated HSC-LX2 cells. Conclusion P. Radix primarily can regulate targets such as HSP90AA1, PTGS2, PPARG, CASP3. TGP, the main active compound of P. Radix, protects against chemical liver injury by reducing the inflammatory response, activating apoptotic proteins, and promoting the apoptosis of activated HSCs.

Objective:Laboratory evaluation of the relationship between cerebrospinal fluid and plasma indicators and intrathecal immunoglobulin G(IgG) synthesis in patients with neurological diseases, and establishment of a new diagnostic method for intrathecal IgG synthesis.Methods:This study retrospectively analyzed the content of IgG in cerebrospinal fluid samples and blood albumin in blood samples, and other test results of 410 patients with neurological diseases who visited Beijing Tiantan Hospital from 2019 to 2022. According to the results of oligoclonal bands in cerebrospinal fluid, patients were divided into intrathecal IgG synthesis group and non-intrathecal IgG synthesis group. The Mann Whitney U test was used for inter group comparison, and a bilateral test with P<0.05 indicates a statistically significant difference. Include indicators with differences between groups in logistic regression analysis, construct a predictive model, and compare it with the established quantitative formula IgG index. Results:There were significant differences in 10 indicators, including cerebrospinal fluid leukocyte count and 24-hour intrathecal IgG synthesis rate, between the intrathecal IgG synthesis group and the non-intrathecal IgG synthesis group, with P<0.05. The area under the curve (AUC) of intrathecal IgG synthesis was higher than the IgG index (AUC=0.920, 0.809, Z=31.178, P<0.001), the sensitivity was higher than the IgG index (0.825, 0.618), and the specificity was lower than the IgG index (0.876, 0.908). Conclusion:The combination of 10 indicators such as cerebrospinal fluid white blood cell count and 24-hour intrathecal IgG synthesis rate can improve the diagnostic efficacy and sensitivity of intrathecal IgG synthesis.

Objective To understand the reliability of caloric test results through the analysis of the pod shape dia-gram types of caloric test and to provide a more accurate and reliable basis for vestibular system function evaluation.Meth-ods The results of caloric test in 528 patients from July 2021 to May 2022 in vertigo diagnosis and treatment center were analyzed.According to pod pattern and unilateral weakness(UW),the patients were divided into five groups:cold and warm test symmetrical group,left and right side asymmetry group,single value significant abnormal group,bilateral hypo-plasia group and pod morphology unable to be classified group.Unreliable data can be identified by comparing,explaining,and summarizing the results of UW of different groups,so as to reduce the interference of unreliable data to clinical diagno-sis and treatment.Results Cold and warm test symmetric group(n=439)included patients with symmetry of bilateral vestibular function(n=273)and decreased vestibular function of one side(n=166).Left and right symmetrical groups in-eluded pationts with bilateral symmetric vestibular function(n=11)and unilateral reduction(n=13).Single value signifi-cant abnormal group showed cases with unilateral vestibular function reduction(n=25)and bilateral symmetric vestibular function(n=11).Bilateral hypolasion group showed cases with bilateral symmetric vestibular function(n=25)and unilat-eral reduction(n=9).Pod morphology unclassified group(n=5)suggested varions interference factors.Conduson When the function of the peripheral vestibular is symmetrical and normal,we should be alert to the existence of temperature effect,and should consider the inspection of the perfusion apparatus and the calibration of the irrigation temperature.When the function of the peripheral vestibular shows unilateral weakness,repeating the irrigation is recommended when the single value of the caloric test significantly increases or decreases.If there is no change,repeating the irrigation at the same tem-perature in the other ear or even repeating the whole caloric test are recommended.The UW value could not truly reflect the state of peripheral vestibular function when the caoric test produces bilateral weakness.Therefore,water irrigation could be used to make a correct judgment based on the medical history and other auxiliary examinations.It is of great significance to judge the effectiveness of caloric test comprehensively by combining the morphology of pod diagram with UW value.
