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.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective To explore the research progress, research hotspot and development trend of tigecycline resistance based on the quantitative analysis and visualization function of CiteSpace. Methods The data were collected from 4,263 Chinese and English articles on tigecycline resistance in CNKI, Wanfang, VIP and Web of Science (WOS) databases from 2012 to 2022. CiteSpace 5.8.R3 software was used to analyze the cooperative network of authors, the cooperative network of countries and institutions, the total citation times of journals, and keywords included in the literature, to reveal the hotspots and trends of tigecycline resistance research. Results The number of articles published in English literature was higher than that in Chinese literature. China had the largest number of published documents, showing a significant international academic influence in this research field. Countries all over the world were concerned about the resistance of tigecycline, but Chinese literatures focused more on the clinical infection and prevention of tigecycline resistance, while English literatures placed special emphasis on the research about the drug resistance mechanism of tigecycline. Conclusion The research direction at home and abroad is basically the same, but the research focus has gradually shifted from the clinical treatment and monitoring of tigecycline to the molecular level of drug resistance mechanism.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.

BACKGROUND:Exercise has a regulatory effect on intestinal flora dysbiosis,which can effectively protect the beneficial flora and improve the intestinal environment.However,the effect of treadmill exercise on the structure and diversity of intestinal microbial community in Parkinson's disease and the specific mechanism are not clear. OBJECTIVE:Using 16S rDNA technique to analyze the effect of treadmill exercise on the structure and diversity of the intestinal flora of rats with Parkinson's disease,and to investigate the mechanism of non-pharmacological treadmill exercise to improve Parkinson's disease. METHODS:Twelve of the 18 Sprague-Dawley rats were randomly selected to make animal models of Parkinson's disease using unilateral 2-point nigrostriatal injection of 6-hydroxydopamine.The remaining six rats were used as sham-operation group,which were injected with the same dose of saline containing 0.2%ascorbic acid using the same positioning and injection method.After successful modeling,12 rats with Parkinson's disease were randomly divided into model group and treadmill exercise group(n=6 per group).The treadmill exercise group was subjected to a middle and low intensity tread mill exercise,10 m/min,30 minutes per day,5 days per week for 4 weeks.Fresh feces were collected and stored in liquid nitrogen 24 hour after the last exercise session,and the changes in fecal flora were analyzed by 16S rDNA sequencing technique. RESULTS AND CONCLUSION:Treadmill exercise significantly improved behavior and nigrostriatal tyrosine hydroxylase-positive cell expression in rats with Parkinson's disease model and alleviated changes in the structure and diversity of the gut microbial community caused by Parkinson's disease,increased the number of operational taxonomic units and modulated Alpha and Beta diversity in rats.At the phylum and genus levels,the abundance ratio of Firmicutes/Bacteroidetes in the model group decreased compared with the sham-operated group,while beneficial bacteria such as Prevotella,Bacteroides,and Clostridium_XlV increased significantly after treadmill exercise.To conclude,treadmill exercise has a significant modulating effect on behavioral abnormalities,toxic damage to dopaminergic neurons and gut microbial imbalance caused by Parkinson's disease,alleviates the symptoms of flora-related diseases,and has a positive effect on the improvement of Parkinson's disease.

Objective In this study, a strain of colistin and tigecycline-resistant bacteria isolated in 2009 was analyzed, and the structure of drug-resistant plasmid and genetic environment were discussed, so as to provide basis for the prevention and control of multidrug-resistant bacteria. Methods A strain (GZ12244) with positive mcr and tet(M) was obtained by screening colistin and tigecycline resistance genes. Vitek-2 was used for strain identification, and the drug sensitivity test was carried out by broth dilution method. The molecular typing, drug resistance genes, insertion sequences, plasmid structure and genetic background were analyzed by genome-wide sequencing and bioinformatics. Results Strain GZ12244 is Klebsiella pneumoniae, which is resistant to colistin B, tigecycline, cefuroxime and tetracycline, and carries a variety of drug-resistant related genes such as mcr-1 and tet(M), and some of the drug-resistant genes with antibiotic efflux and antibiotic target change have amino acid substitution mutations. Mcr-1 and tet(M) coexist in a plasmid, and mcr-1 flanked by two insertion sequences ISApl1. There are insertion sequences such as IS15, IS1D and ISEc63 in the upstream and downstream of tet(M) gene. Conclusion Klebsiella pneumoniae GZ12244 is a multidrug-resistant strain. The drug-resistant gene exists in plasmid, and the mobile elements in upstream and downstream may spread the drug-resistant gene.

Objective To investigate the clinical efficacy of preoperative therapeutic plasma exchange(TPE)in pre-venting acute rejection after ABO incompatible kidney transplantation(ABOi-KT).Methods Nine patients with ABOi-KT who were admitted to the renal transplant department of our hospital from April 2022 to April 2024 were retrospectively ana-lyzed.They received a total of 28 TPEs before kidney transplantation,and the treatment plan was summarized as follows:The proportion of the substitute fluid,as well as the frequency and volume of TPE were determined based on the patient′s ABO blood group system antibody titer,gender,height,weight,hematocrit and other indicators upon admission.The pa-tient′s relevant laboratory indicators,including hemoglobin,platelets,leukocytes,coagulation function,total protein,albu-min,globulin,A/G,creatinine and urea nitrogen upon admission and after TPE were monitored and statistically analyzed.After transplantation,changes in renal function indicators such as ABO blood group system antibody titers,creatinine and u-rinary excretion were observed,and clinical symptoms of acute rejection,such as swelling,pain and edema in the transplan-ted kidney area were observed.Results Nine ABOi-KT patients had an average of about 3 TPEs before transplantation sur-gery,with an average total volume of approximately 2 500 mL to 3 500 mL per TPE,or approximately about 1.01 to 1.16 plasma volume(PV).After multiple TPEs,pre-transplantation antibody titers decreased by an average of 3 times compared to before TPE.There were no statistically significant differences in Hb,PLT,PT,PTA,INR,TBil,ALB,Cr and BUN(P＞0.05),while statistically significant differences were found in WBC,APTT,Fbg,TP,GLB and A/G(P＜0.05).After surgery,the creatinine level of 9 patients dropped to approximately 100 to 140 μmol/L,the urine output was normal,and the urine protein dropped to weakly positive or negative values.None of the nine patients experienced acute rejection.Con-clusion TPE can effectively reduce the level of ABO blood group antibody and prevent the occurrence of acute rejection in ABOi-KT patients.

Objective:Differences between randomized controlled trial (RCT) results and real world study (RWS) results may not represent a true efficacy-effectiveness gap because efficacy-effectiveness gap estimates may be biased when RWS and RCT differ significantly in study design or when there is bias in RWS result estimation. Secondly, when there is an efficacy- effectiveness gap, it should not treat every patient the same way but assess the real-world factors influencing the intervention's effectiveness and identify the subgroup likely to achieve the desired effect.Methods:Six databases (PubMed, Embase, Web of Science, CNKI, Wanfang Data, and VIP) were searched up to 31 st December 2022 with detailed search strategies. A scoping review method was used to integrate and qualitatively describe the included literature inductively. Results:Ten articles were included to discuss how to use the RCT research protocol as a template to develop the corresponding RWS research protocol. Moreover, based on correctly estimating the efficacy-effectiveness gap, evaluate the intervention effect in the patient subgroup to confirm the subgroup that can achieve the expected benefit-risk ratio to bridge the efficacy-effectiveness gap.Conclusion:Using real-world data to simulate key features of randomized controlled clinical trial study design can improve the authenticity and effectiveness of study results and bridge the efficacy-effectiveness gap.

Objective:Randomized controlled trials (RCT) usually have strict implementation criteria. The included subjects' characteristics of the conditions for the intervention implementation are quite different from the actual clinical environment, resulting in discrepancies between the risk-benefit of interventions in actual clinical use and the risk-benefit shown in RCT. Therefore, some methods are needed to enhance the extrapolation of RCT results to evaluate the real effects of drugs in real people and clinical practice settings.Methods:Six databases (PubMed, Embase, Web of Science, CNKI, Wanfang Data, and VIP) were searched up to 31 st December 2022 with detailed search strategies. A scoping review method was used to integrate and qualitatively describe the included literature inductively. Results:A total of 12 articles were included. Three methods in the included literature focused on: ①improving the design of traditional RCT to increase population representation; ②combining RCT Data with real-world data (RWD) for analysis;③calibrating RCT results according to real-world patient characteristics.Conclusions:Improving the design of RCT to enhance the population representation can improve the extrapolation of the results of RCT. Combining RCT data with RWD can give full play to the advantages of data from different sources; the results of the RCT were calibrated against real-world population characteristics so that the effects of interventions in real-world patient populations can be predicted.

The clinical demand for occlusal reconstruction increases rapidly with increasing number of patients who have lost their normal occlusion because of tooth wear and dentition defects.Occlusal reconstruction is a special type of restoration defined as a comprehensive restoration of the function of the stomatognathic system by reestablishing a uni-form and stable occlusal relationship between the upper and lower dentitions.Occlusal function analysis is an important part of occlusal reconstruction to achieve accurate restora-tion design and adjustment.Digital occlusal function analysis was conducted to monitor the movement of the mandible and obtain related data for the parameter design of occlusal reconstruction.Preoperative design,intraoper-ative adjustment,and postoperative verification were achieved,thereby improving the efficiency and accuracy of occlusal reconstruction.
