In recent years,the global prevalence of myopia has remained high,seriously endangering the eye health of adolescents.A large number of studies have confirmed that orthokeratology lens can control or delay the progression of my-opia and reduce the incidence of fundus lesions in high myopia.Although the efficacy of myopia control with orthokeratolo-gy has been widely recognized,its exact mechanism of action is still unclear,and there are many hypotheses.This paper re-views the role of factors such as accommodation,defocus,choroidal thickness,high-order aberrations and biomechanics in myopia control with orthokeratology,and explores how these factors jointly affect the development of myopia.

Patient-Reported Outcomes(PRO)is a subjective outcome indicator based on the concept of"patient-centered",in which patients report their own information such as health status,functional status,and treatment feelings,which is an ef-fective supplement to traditional objective outcome indicators.Based on the development status of the Patient Reported Outcome Measure(PROM),it systematically analyzed the concepts related to PRO with the goal of clarifying the Patient Experience Data(PED)with research value,and proposed six core types of PROs in the medical field,including health-related quality of life,health preference,health behavior,symptom burden,functional status and patient-reported experience.For each type of PRO,the key characteristics of the study were analyzed,the evidence and application directions of related PED and the production based on PED were described,and the existing international mainstream PROMs were reviewed.It is hoped that the connotation of PRO-related concepts can be comprehensively expounded,and PEDs with research significance and value can be explored,so as to provide guidance for the focus of PRO-related research in China,so as to promote the application and development of PRO in China.

Patient-Reported Outcomes(PRO)refers to a subjective outcome measure based on the concept of"patient-cen-tered",in which patients report their own health status,functional status,treatment feelings and other information,which is an ef-fective supplement to traditional objective outcome indicators.With the continuous promotion of PRO research,its application in the world is also constantly enriched.It takes the different application scenarios of PRO as the starting point and the evidence-based evidence that PRO can generate as the evaluation object,reviews the application status of PRO in the US,the European Union,the UK,Canada and other countries,regions or organizations,and summarizes the main application methods of PRO in different medical decision-making scenarios,in order to provide international experiences for the application research of PRO in China.

Acute myeloid leukemia (AML) is a malignant disease of myeloid hematopoietic stem/progenitor cells. Although new drugs have emerged in recent years, the status of hematopoietic stem cell transplantation (HSCT) in AML still remains irreplaceable. This article reviews the adjustment of indications for HSCT in AML, donor selection, and updates of conditioning regimens, new prevention strategies for post-transplant relapse, new targeted drugs, immunotherapy combined with HSCT to improve the prognosis of relapsed and refractory AML, and optimization of transplantation technology for elderly AML.

Objective:To summarize the clinical features, laboratory findings, treatment and prognosis of children confirmed as Mycoplasma pneumoniae-induced rash and mucositis (MIRM) in children. Methods:This retrospective study concluded 6 children diagnosed as MIRM in Department of Gastroenterology and Infectious Diseases, Shanghai Children′s Hospital, School of Medicine, Shanghai Jiao Tong University from August 2023 to April 2024. This paper described the characteristics of MIRM and analyzed the therapeutic strategy and prognosis.Results:A total of 6 children were diagnosed as MIRM including 2 boys and 4 girls with an age of onset was 6.4 (3.1, 7.5) years. Among the 6 patients, 4 patients had oral mucosal involvement among whom 2 showed crusting of the lips. Four patients had ocular involvement manifesting as conjunctival congestion and increased secretion. All patients presented with skin lesions, manifesting as target-shaped damage in 4 cases, herpes herpetiformis in 1 case and purpura-like rash in 1 case. Serological tests for Mycoplasma pneumoniae IgM and Mycoplasma pneumoniae nucleic acid test were positive in all 6 cases. Two cases received intravenous immunogloblin infusion combined with methylprednisolone, monotherapy of methylprednisolone in 4 cases. The course of glucocorticoids was 1-7 weeks, and the initial dose was 2-4 mg/(kg·d), which was gradually reduced according to the rash. The children were followed up for 3 to 9 months, no case suffered from long term ocular or cutaneous complications or recurrence of rash. All cases had good prognosis. Conclusions:Children diagnosed as MIRM present with mild symptoms and usually have good prognosis with early identification and appropriate intervention. Individualized therapy should be applied based on the severity of skin involvement.

Objective To evaluate the test-retest reliability of the ballistic push-up(BPU)test and establish predictive models for upper-limb strength and explosive power in young males.Methods A total of 71 male college students performed assessments of upper-limb bench press 1 repetition maximum(1RM)strength,bench press explosive power,and two BPU tests with a 48-hour interval.BPU test data were recorded using a three-dimensional(3D)force platform and motion capture system to calculate concentric metrics such as peak force(PF)and mean velocity(MV).The intraclass correlation coefficient(ICC)was used to examine the retest reliability of the BPU test.The Pearson correlation coefficient was used to evaluate the correlation of the BPU metrics with upper-limb strength and explosive power.Predictive models for upper-limb strength and explosive power were created using stepwise regression analysis.Results BPU metrics showed a good test-retest reliability(ICC=0.764-0.935).PF and MV,along with body weight(BW),were effective predictors of bench press 1RM in young males:bench press 1RM=0.129PF-16.772[R2=0.790,standard error of the estimate(SEE)=8.17 kg];bench press 1RM=1.511BW+87.15 MV-110.136(R2=0.767,SEE=8.60 kg).PF and BW were also predictors of bench press explosive power:bench press explosive power=2.755BW+0.287PF-17.351(R2=0.620,SEE=46.1 W).Conclusions The BPU test demonstrates a good test-retest reliability,and PF and MV from the BPU test can be used to predict upper-limb strength and explosive power in young males.

In situ tumor vaccine has become an important strategy in cancer immunotherapy owing to its ability to induce immune responses locally and overcome tumor heterogeneity. However, the abnormal structure and mechanical properties of the tumor’s physical microenvironment significantly limit the efficiency of vaccine delivery and immune efficacy. In this review, the key factors in the tumor’s physical microenvironment, including solid pressure, interstitial fluid pressure, matrix stiffness, and tissue microstructure, are systematically discussed. Their obstructive roles in immune cell infiltration, antigen presentation, and immune activation are analyzed. The potential of approaches, such as radiotherapy, anti-angiogenic therapy, extracellular matrix degradation agents, nanomaterials, and hydrogel delivery platforms, in reshaping the tumor’s physical microenvironment is explored. This review aims to offer theoretical and practical guidance for optimizing in situ vaccine strategies through the regulation of the tumor’s physical microenvironment, ultimately advancing the precision and effectiveness of cancer immunotherapy.

Objective To investigate the mechanism by which angiopoietin-like protein 8(ANGPTL8)regulates vascular smooth muscle cell(VSMCs)apoptosis.Methods An in vitro abdominal aortic aneurysm cell model was established by stimulating human VSMCs(HUSMCs)with angiotensin Ⅱ(AngⅡ).Stable ANGPTL8 knockdown and over-expression VSMC cell strains were generated using lentiviral transfection.TUNEL staining was used to de-tect apoptosis.Western blot analysis was performed to measure the protein expression of ANGPTL8,caspase9,caspase3,Bcl-2,Bax,p53,and PUMA,while RT-qPCR was used to assess mRNA expression of ANGPTL8,Bcl-2 and Bax.Results AngⅡ significantly induced ANGPTL8 expression in HVSMCs in a time-and dose-de-pendent manner(P＜0.05).ANGPTL8 knockdown significantly reduced the expression of apoptosis-related proteins caspase9,caspase3,and Bax,while increased the expression of the anti-apoptotic protein Bcl-2(P＜0.05).Con-versely,ANGPTL8 over-expression markedly induced HVSMCs apoptosis,which was significantly suppressed by treatment with the p53 pathway inhibitor pifithrin-α(PFT-α).Conclusions ANGPTL8 may promote VSMC apop-tosis by activation of p53 signaling pathway.
