OBJECTIVES: To investigate the readmission rate and risk factors for readmission due to hyperbilirubinemia in neonates with ABO hemolytic disease of the newborn (ABO-HDN), and to construct a risk prediction model for readmission. METHODS: Neonates diagnosed with hyperbilirubinemia due to ABO-HDN and hospitalized in the neonatal department between January 2021 and December 2023 were enrolled. Based on readmission status, neonates were divided into a readmission group and a control group. Clinical characteristics related to hyperbilirubinemia and risk factors for readmission were analyzed. Subsequently, a prediction model for readmission was constructed, and its predictive performance was evaluated. RESULTS: A total of 483 neonates with hyperbilirubinemia due to ABO-HDN were included. The readmission rate was 13.0% (63 cases). Multivariate logistic regression analysis revealed that earlier age at phototherapy initiation, longer duration of phototherapy, occurrence of rebound hyperbilirubinemia, and higher levels of serum total bilirubin and indirect bilirubin at discharge were independent risk factors for hyperbilirubinemia readmission in ABO-HDN neonates (OR=2.373, 4.840, 6.475, 5.033, 1.336 respectively; P<0.05). A risk prediction model for ABO-HDN hyperbilirubinemia readmission was constructed based on these 5 risk factors. Model evaluation demonstrated good predictive performance. CONCLUSIONS Age at phototherapy initiation, duration of phototherapy, occurrence of rebound hyperbilirubinemia, and serum total bilirubin and indirect bilirubin levels at discharge are significant influencing factors for readmission due to hyperbilirubinemia in neonates with ABO-HDN. Close monitoring during discharge planning and follow-up management for such neonates is crucial to reduce readmission rates.

Several types of arthritis share the common feature that the generation of inflammatory mediators leads to joint cartilage degradation. However, the shared mechanism is largely unknown. H2BK120ub1 was reportedly involved in various inflammatory diseases but its role in the shared mechanism in inflammatory joint conditions remains elusive. The present study demonstrated that levels of cartilage degradation, H2BK120ub1, and its regulator WW domain-containing adapter protein with coiled-coil (WAC) were increased in cartilage in human rheumatoid arthritis (RA) and osteoarthritis (OA) patients as well as in experimental RA and OA mice. By regulating H2BK120ub1 and H3K27me3, WAC regulated the secretion of inflammatory and cartilage-degrading factors. WAC influenced the level of H3K27me3 by regulating nuclear entry of the H3K27 demethylase KDM6B, and acted as a key factor of the crosstalk between H2BK120ub1 and H3K27me3. The cartilage-specific knockout of WAC demonstrated the ability to alleviate cartilage degradation in collagen-induced arthritis (CIA) and collagenase-induced osteoarthritis (CIOA) mice. Through molecular docking and dynamic simulation, doxercalciferol was found to inhibit WAC and the development of cartilage degradation in the CIA and CIOA models. Our study demonstrated that WAC is a key factor of cartilage degradation in arthritis, and targeting WAC by doxercalciferol could be a viable therapeutic strategy for treating cartilage destruction in several types of arthritis.

Traditional development of small protein scaffolds has relied on display technologies and mutation-based engineering, which limit sequence and functional diversity, thereby constraining their therapeutic and application potential. Protein design tools have significantly advanced the creation of novel protein sequences, structures, and functions. However, further improvements in design strategies are still needed to more efficiently optimize the functional performance of protein-based drugs and enhance their druggability. Here, we extended an evolution-based design protocol to create a novel minibinder, BindHer, against the human epidermal growth factor receptor 2 (HER2). It not only exhibits super stability and binding selectivity but also demonstrates remarkable properties in tissue specificity. Radiolabeling experiments with ^99mTc, ⁶⁸Ga, and ¹⁸F revealed that BindHer efficiently targets tumors in HER2-positive breast cancer mouse models, with minimal nonspecific liver absorption, outperforming scaffolds designed through traditional engineering. These findings highlight a new rational approach to automated protein design, offering significant potential for large-scale applications in therapeutic mini-protein development.

Objective To explore the clinical features,treatment and prognosis of glioblastomas(GBM)in adults.Methods A retrospective cohort study was performed on 176 adult GBM patients admitted to our department from January 2015 to December 2021.Chi-square test was used to investigate the clinical differences between isocitrate dehydrogenase(IDH)mutant and wild-type GBM.Kaplan-Meier and Log-Rank tests were employed to plot survival curve and compute the survival analysis.Multivariate Cox regression model was applied to identify the independent prognostic factors.Results IDH wild-type GBM account for 89.2％and had significantly differences from the IDH-mutant GBM in terms of age of onset,Karnofsky(KPS)score at admission,symptoms of neurological deficit,and methylation status of O6-methylguanine-DNA-methyltransferase(MGMT)promoter(P＜0.05).For the IDH wild-type GBM patients receiving conventional therapy,univariate Cox hazard analysis showed gross total resection,methylation of MGMT promoter,initiation of radiation within the 5th to 6th week after surgery,and adjuvant temozolomide(TMZ)chemotherapy ≥6 cycles were favorable prognostic factors for overall survival(OS);GBMs in the left hemisphere,involvement of single lobe,methylation of MGMT promoter,and initiation of radiation within the 5th to 6th week after surgery were favorable prognostic factors for progression free survival(PFS)(all P＜0.05).Moreover,multivariate Cox hazard regression analysis indicated that methylation of MGMT promoter,and initiation of radiation within the 5th to 6th week after surgery,and adjuvant TMZ chemotherapy ≥6 cycles were independent protective factors for OS,and GBMs in the left hemisphere,involvement of single lobe and methylation of MGMT promoter were independent protective factors for PFS in the GBM patients(all P＜0.05).Conclusion The clinical and prognostic features are totally different between IDH mutant and wild-type GBM,and molecular detections are needed for the further pathological classification.Methylation of MGMT promoter is a primary marker of favorite prognosis for IDH wild-type GBM,and slightly delay in radiotherapy(the 5th to 6th week after surgery)can effectively improve the survival prognosis of IDH wild-type GBM.

Objective To investigate the effect and mechanism of lycium barbarum polysaccharide(LBP)on hepatocyte injury induced by homocysteine(Hcy).Methods Normal C3H/An mouse hepatocytes(NCTC 1469)were cultured in vitro and treated with different concentrations of Hcy(0,50,100,200,500 μmol/L).The optimal concentrations of Hcy-treated NCTC 1469 cells were detected by MTT assay.When the cells reached the logarithmic growth stage,the conditions were set up as follows:(1)control group(cultured with DMEM medium supplemented with 10%horse serum)and Hcy group(treated with 100 μmol/L Hcy solution for 48 h),and the cells were collected.Cell viability staining was used to detect apoptosis,aspartate aminotransferase(AST)/alanine aminotransferase(ALT)activity detection kit was used to detect AST and ALT activities,RT-qPCR was used to detect the expression levels of YAP1,DNMT1,DNMT3a and DNMT3b mRAN,and Western blotting was used to detect the expression of YAP1 protein,nested methylation specific PCR(nMS-PCR)was used to detect DNA methylation rates in the YAP1 promoter region.(2)Control group,LBP group,Hcy group and Hcy+LBP group.LBP group was treated with 4 mg/ml LBP solution for 2 h,Hcy group and Hcy+LBP group were treated with 100 μmol/L Hcy solution for 48 h,and Hcy+LBP group was treated with 4 mg/ml LBP solution at 46 h,and the cells were collected.The expression levels of YAP1,DNMT1,DNMT3a and DNMT3b mRAN were detected by RT-qPCR;the expression of YAP1,Bax and Bcl-2 proteins was detected by Western blotting;AST/ALT activity detection kit was used to detect AST and ALT activities.Prediction of DNA methylation CpG islands in YAP1 promoter region by bioinformatics.Results NCTC 1469 cells were treated with 100 μmol/L Hcy according to the results of MTT assay.Compared with control group,the apoptosis rate of Hcy group increased(P<0.01),the activities of ALT and AST increased(P<0.001),the mRAN and protein expression levels of YAP1 decreased(P<0.001),and the methylation rate of YAP1 promoter region increased(P<0.01),the mRNA expression levels of DNMT1,DNMT3a and DNMT3b increased(P<0.01 or P<0.001).Compared with Hcy group,the mRNA expression levels of DNMT1,DNMT3a and DNMT3b in the Hcy+LBP group decreased(P<0.001),the mRAN and protein expression levels of YAP1 significantly increased(P<0.01 or P<0.001).In addition,in the Hcy+LBP group,cells showed significantly elevated of Bcl-2 protein(P<0.001),but decreased Bax protein(P<0.001),and decreased activities of ALT and AST(P<0.001).Conclusions The decrease of YAP1 expression may be the key process of Hcy induced injury of NCTC 1469 cells,and the methylation of the YAP1 promoter region may be the molecular mechanism of Hcy induced YAP1 expression change.LBP may improve NCTC 1469 cell damage induced by Hcy by positively regulating YAP1 expression.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

【Objective】 To compare the desalination effects of five desalination methods and their effects on the components for human coagulation factor Ⅷ(FⅧ), and provide reference for selection of protein desalination methods. 【Methods】 Sephadex G-25 Medium gel, Fractogel EMD BioSEC gel, ultrafiltration, room temperature dialysis and 4℃ dialysis were used to desalt human FⅧ. The desalination effect was evaluated by the removal rate of Na +, citrate ion and glycine. FⅧ protein recovery, FⅧ activity (FⅧ∶C), VWF antigen (VWF∶Ag), VWF activity(VWF∶Ac), VWF polymers and SDS-PAGE analysis before and after desalination were compared to evaluate the effect of desalination on FⅧ components. 【Results】 In terms of desalination effect, the removal rate of Na⁺ was the lowest in ultrafiltration desalination, while that of Fractogel EMD BioSEC gel was the highest [(97.90±0.06) % vs (99.82±0.07) %]. Except that there was no statistical significance between Sephadex G-25 Medium gel desalination and Fractogel EMD BioSEC gel desalination (P=0.90), the removal rates of the other four methods were statistically significant. The removal rate of glycine was the lowest in ultrafiltration desalination, wihle that of Fractogel EMD BioSEC gel desalination was the highest [(95.78±0.42) % vs (99.81±0.08) %]. Significant difference in glycine removal was noticed in ultrafiltration desalination, but not among the other four desalination methods. There was no significant difference in the removal rate of citrate ions among the five methods (P=0.85). For the effect of FⅧ components, FⅧ∶C, VWF∶Ag, VWF∶Ac and protein recovery rates of ultrafiltration desalination were the highest, with (18.34±1.99) IU/mL, (11.81±0.33) IU/mL, (12.26±0.58) IU/mL and (97.13±1.37) %, respectively. There was no significant change in VWF∶Ac/VWF∶Ag before and after desalination by the five methods. SDS-PAGE and VWF polymer analysis showed that different desalination methods had no significant impact on protein composition. 【Conclusion】 Although different desalination methods had no significant effect on the composition of FⅧ protein, the desalination effect was different. Moreover, different desalination methods had significant effects on protein recovery, FⅧ∶C, VWF∶Ag and VWF∶Ac. The selection of desalination methods should be more considered during protein processing,

Objective To analyze the epidemiological characteristics and epidemic situation of children with Kashin-Beck disease (KBD) in China,and provide the basis for formulating prevention and control measures. Methods Fixed-point monitoring,moving-point monitoring,and full coverage of monitoring were promoted successively from 1990 to 2023. Some children (7-12 years old) underwent clinical and right-hand X-ray examinations every year. According to the KBD diagnosis criteria,clinical and X-ray assessments were used to confirm the diagnosis. Results In 1990,the national KBD detectable rate was 21.01％. X-ray detection decreased to below 10％ in 2003 and below 5％ in 2007. Between 2010 and 2018,the prevalence of KBD in children was less than 0.4％,which fluctuated at a low level,and has decreased to 0％ since 2019. Spatial epidemiological analysis indicated a spatial clustering of adult patients prevalence rate in the KBD areas. Conclusion The evaluation results of the elimination of KBD in China over the last 5 years showed that all villages in the monitored areas have reached the elimination standard. While the adult KBD patients still need for policy consideration and care.
