Introduction There is currently no standard treatment for relapsed and arsenic trioxide(ATO)-resistant acute promyelocytic leukemia(APL).Here,we report a case series of realgar-indigo naturalis formula(RIF)for the successful treatment of patients with relapsed and ATO-resistant *** presentation Two patients in the first relapse and one in the second relapse failed to achieve hematologic complete remission(HCR)when reinduced by ATO;the other five patients progressed to relapse during ATO-based regimens for post-remission *** eight patients received RIF in three doses per day totaling 130 mg/kg(≤30 pills)as induction therapy and achieved HCR at a median time of 46.5 *** received 5 years of post-remission therapy,which consisted of combined chemotherapy followed by *** this period,the patients did not experience renal dysfunction or QT interval *** the last follow-up,three patients survived without relapse,two patients survived with a second or third relapse and third or fourth remission,and the other three patients relapsed for a third or fourth time and *** 5-year overall survival and event-free survival rates were 75.0%(95%confidence interval[CI]:31.5–93.1)and 37.5%(95%CI:5.6–71.7),*** RIF for induction therapy and RIF combined with chemotherapy for post-remission therapy may represent an effective and safe protocol for the treatment of patients with relapsed and ATO-resistant APL.

Glucose-6-phosphate dehydrogenase(G6PD)deficiency is one of the most prevalent hereditary and X-linked enzyme disorders caused by the pathogenetic G6PD(NM_001042351.2)variants(Yang et al.,2016).The clinical manifestations of G6PD deficiency offer a wide spectrum of diverse disease phenotypes(Hecker et al.,2013).Investigations of prevalence and molecular epidemiology demonstrate that G6PD deficiency affects over 400 milion individuals worldwide and leads to thousands of deaths annually(Mortality and Causes of Death,2015).

Peeling strength can comprehensively reflect slider track safety and is crucial in car seat safety assessments. Current methods for determining slider peeling strength are primarily physical testing and numerical simulation. However, these methods encounter the potential challenges of high costs and overlong time consumption which have not been adequately addressed. Therefore, the efficient and low-cost surrogate model emerges as a promising solution. Nevertheless, currently used surrogate models suffer from inefficiencies and complexity in data sampling, lack of robustness in local model predictions, and isolation between data sampling and model prediction. To overcome these challenges, this paper aims to set up a systematic framework for slider track peeling strength prediction, including sensitivity analysis, dataset sampling, and model prediction. Specifically, the interpretable linear regression is performed to identify the sensitivity of various geometric variables to peeling strength. Based on the variable sensitivity, a distance metric is constructed to measure the disparity of different variable groups. Then, the sparsity-targeted sampling(STS) is proposed to formulate a representative dataset. Finally, the sequentially selected local weighted linear regression(SLWLR) is designed to achieve accurate track peeling strength prediction. Additionally, a quantitative cost assessment of the supplementary dataset is proposed by utilizing the minimum adjacent sample distance as a mediator. Experimental results validate the efficacy of sequential selection and the weighting mechanism in enhancing localization ***, the proposed SLWLR method surpasses similar approaches and other common surrogate methods in terms of prediction performance and data quantity requirements, achieving an average absolute error of 3.3 kN in the simulated test dataset.
