Objective:To evaluate the efficacy of corticosteroids in male children with Duchenne muscular dystrophy (DMD), and provide evidence for the rational clinical use of medication.Methods:This was a multicenter medical record series study which conducted from January 15 th to March 14 th, 2025. A total of 53 male children with DMD admitted to the Department of Rehabilitation of Children′s Hospital, Zhejiang University School of Medicine, Children′s Hospital of Chongqing Medical University and Affiliated Children′s Hospital of Soochow University from 2020 to 2024 were enrolled. Clinical data, corticosteroid usage, and the follow-up data were collected. The North star ambulatory assessment (NSAA) was used as the primary efficacy indicator. Generalized estimating equations (GEE) exchangeable working matrices were used for longitudinal analysis, and the least squares mean were used to compare the change trend of the efficacy evaluation index across different medication durations. Results:The age at the initiation of corticosteroid treatment was (6.3±1.9) years. The follow-up duration was 1.2 (0.9, 2.2) years. After treatment, the raw scores and linear scores of NSAA were both significantly higher than those before treatment ((22±7) vs. (19±5) points, (60±16) vs. (53±8) points; t=3.98, 3.69; both P<0.001). The 10 meter running time and time rising from floor were both shorter than those before treatment (6 (4, 8) vs. 7 (6, 9) s, 5 (3, 6) vs. 6 (5, 9) s; Z=2.62, 3.47; both P<0.01). GEE model analysis revealed all nonlinear correlation between motor function (NSAA linear score, 10-meter running velocity, and rising from floor velocity) and the duration of corticosteroid treatment (all P<0.05). Least squares mean comparison all showed that the medication effect first increased and then decreased with duration, reaching the peak at 1.1-2.0 years after treatment (all P<0.05). Conclusions:Corticosteroids can improve the motor function in male children with DMD, with the maximum treatment effect occurring 1 to 2 years after the initiation of treatment. It is necessary to comprehensively leverage time-varying efficacy of corticosteroids to optimize individualized treatment regimens for maximal motor function benefits in children with DMD.

Radiotherapy,as one of the important means of treating cancer,is more prone to medical errors than other treatment methods due to its involvement of a wide variety of equipment,high demands for personnel collaboration,and relatively complex treatment processes.Therefore,the establishment of an effective reporting and learning system for adverse events of radiotherapy is of great significance for ensuring patients'safety and improving healthcare quality.The International Atomic Energy Agency(IAEA)has established the Safety Reporting And Learning System For Radiotherapy(SAFRON),which constructed comprehensive database and formulated standard procedures of reporting event and analytical methods through collected and analyzed the worldwide cases of adverse event of radiotherapy.At the same time,the SAFRON system emphasizes the cultivation for safety culture,and encourages healthcare professionals to actively report adverse events,and creates a non-punitive learning environment to learn from mistakes and prevent the recurrence of similar incidents.This review introduced the structure and usage method of reporting and learning system of adverse event of SAFRON radiotherapy,so as to understand the using processes,system architecture and security culture of that,which can provide references for the establishment and use of reporting and learning system of adverse event of department,and promote continuous improvement of healthcare quality.

Objective:To analyze the influential factors of hypoalbuminemia in patients with preeclampsia and observe the pregnancy outcomes.Methods:The clinical data of 237 pregnant women with preeclampsia who received treatment in The Sixth Affiliated Hospital of Guangzhou Medical University (Qingyuan People's Hospital) from July 2018 to December 2020 were retrospectively collected and analyzed. These patients were divided into hypoproteinemia (observation group) and no hypoproteinemia (control group) groups according to whether they had hypoproteinemia. The general situation, clinical data, and adverse maternal and infant outcomes were statistically analyzed. Risk factors of hypoalbuminemia were analyzed using a logistic regression model. The predictive efficacy was evaluated using the receiver operating characteristic curve.Results:There were no significant differences in general data between the two groups (all P > 0.05). Multivariate analysis showed that D-dimer ( OR = 1.25, P = 0.004), 24-hour urinary protein ( OR = 1.29, P < 0.001), and total bile acid ( OR = 1.08, P = 0.010) were the independent risk factors for hypoproteinemia in preeclampsia. The predictive efficacy of these three indicators (area under the receiver operating characteristic curve = 0.855, P < 0.001) was greater than that of a single indicator. The incidences of adverse maternal and infant outcomes including placental abruption (9.4%, P = 0.019), liver and kidney dysfunction (34.4%, P < 0.001), pleural and ascitic fluid (28.1%, P = 0.001), fetal intrauterine growth restriction (50.0%, P = 0.001), fundus lesions (6.2%, P = 0.018), HELLP syndrome (9.4%, P = 0.019), mild neonatal asphyxia (15.6%, P = 0.022), severe asphyxia (6.2%, P = 0.049), metabolic acidosis (12.5%, P = 0.001), intrauterine infection (12.5%, P = 0.004), and neonatal hospitalization for more than 20 days (37.5%, P < 0.001) were greater in the observation group compared with the control group. There were no significant differences in postpartum hemorrhage, eclampsia, respiratory distress syndrome, fetal loss, and neonatal death between the two groups (all P > 0.05). Conclusion:D-dimer, 24-hour urinary protein, and total bile acid are independent risk factors for hypoproteinemia in preeclampsia. Patients with preeclampsia complicated by hypoproteinemia have a high risk of adverse maternal and infant outcomes.

Transcriptional regulators (TRs) participate in essential processes in cancer pathogenesis and are critical therapeutic targets. Identification of drug response-related TRs from cell line-based compound screening data is often challenging due to low mRNA abundance of TRs, protein modifications, and other confounders (CFs). In this study, we developed a regression-based pharmacogenomic and ChIP-seq data integration method (RePhine) to infer the impact of TRs on drug response through integrative analyses of pharmacogenomic and ChIP-seq data. RePhine was evaluated in simulation and pharmacogenomic data and was applied to pan-cancer datasets with the goal of biological discovery. In simulation data with added noises or CFs and in pharmacogenomic data, RePhine demonstrated an improved performance in comparison with three commonly used methods (including Pearson correlation analysis, logistic regression model, and gene set enrichment analysis). Utilizing RePhine and Cancer Cell Line Encyclopedia data, we observed that RePhine-derived TR signatures could effectively cluster drugs with different mechanisms of action. RePhine predicted that loss-of-function of EZH2/PRC2 reduces cancer cell sensitivity toward the BRAF inhibitor PLX4720. Experimental validation confirmed that pharmacological EZH2 inhibition increases the resistance of cancer cells to PLX4720 treatment. Our results support that RePhine is a useful tool for inferring drug response-related TRs and for potential therapeutic applications.

OBJECTIVE:To explore the effect of different plasmapheresis supplement timing on therapeutic efficacy of toxic liver injury. METHODS:96 patients with toxic liver injury and divided into group A,B ,C and D with 32 cases in each group ac-cording to different plasmapheresis supplement timing. All patients received plasmapheresis supplement based on routine treatment. In group A,synchronized fluid replacement was 100% fresh plasma;in group B,synchronized fluid replacement was 40% normal saline firstly,and then 60%fresh plasma;in group C,substitute liquid was given till the in vitro blood reached 12%of circulation amount,supplement order as 40% normal saline for the first supplement,and then add 60% fresh plasma. The clinical symptoms and signs,liver function,prothrombin activity and blood biochemical indicators were observed in each group before and after treat-ment. RESULTS:Plasmapheresis supplement had good therapeutic efficacy on toxic liver injury;but the time of clinical symptoms and signs disappearance in group C was significantly shorter than that in group A and B,and the group B was significantly shorter the group A,with statistical significance (P<0.05). The plasma bilirubin,prothrombin activity,albumin levels of 3 groups after treatment were significantly better than before,with statistical significance(P<0.05);the group C was better than the group A and B,and the group B was better than the group A,with statistical significance(P<0.05). Compared with before treatment,the lev-els of AST and ALT in 3 groups decreased significantly after treatment,with statistical significance(P<0.05);the group B and C were better than the group A,with statistical significance(P<0.05);the group B and C was similar to each other,without statisti-cal significance(P>0.05). CONCLUSIONS:Different plasmapheresis supplement timing have different effect on toxic liver injury. The supplement method that giving 40% normal saline for the first supplement,and then add 60% fresh plasma when in vitro blood reach 12%of circulation amount has more significant effect.
