Objective:To assess the efficacy and safety of azacitidine combined with lenalidomide in MDS patients and explore potential mechanisms of therapeutic response.Methods:Sixteen MDS patients with TP53 mutations received azacitidine plus lenalidomide at ZhongDa Hospital, Southeast University (January 2021–June 2025). Efficacy and safety were assessed, and TP53 mutation status was correlated with treatment response. Whole-transcriptome sequencing and bioinformatics were used to explore molecular biomarkers associated with therapeutic efficacy.Results:Sixteen patients (median age 69.5 years, range 52–82; 8 males, 8 females) were enrolled. According to the Molecular International Prognostic Scoring System (IPSS-M), 1, 2, and 13 patients were classified as median low, high, and very high risk, respectively. Among 16 TP53-mutated patients, 11 had biallelic mutations and 5 had monoallelic mutations. Overall response rate was 56.3% (9/16), composite complete remission rate (CRc) was 31.3% (5/16), and hematology improvement rate was 25% (4/16). Among TP53-mutated patients, the response rate was 56.3% (9/16), with variant allele frequency dropping from 65.6% to 16.5% in responders ( P=0.017). In patients with TP53 mutations and complex karyotype, response rate was 53.8% (7/13), with 57.1% (4/7) showing disappearance of CK post-treatment. The most common grade 3–4 nonhematologic adverse events were infections (9/16, 56.3% ), including pneumonia (4/16, 25.0% ), gastrointestinal infections (3/16, 18.8% ), perianal infections (1/16, 6.3% ) and sepsis (1/16, 6.3% ). High CBX8 expression may be linked to treatment response. Conclusion:Azacitidine plus lenalidomide is an effective and safe therapy for MDS, including patients with TP53 mutations and complex karyotypes. Treatment markedly reduces TP53 variant allele frequency in responders, and high CBX8 expression may predict therapeutic response.

Objective To study the plasma metabolomics of mice poisoned by different dosage of the combination of diazepam and ethanol,and to reveal the toxicological mechanisms of combined poisoning of diazepam and ethanol.Methods Female Kunming mice were randomly divided into blank group,single and combined poisoning group(n=6),Based on the LD50 of diazepam co-administered with graded ethanol doses,mice in the single-drug and combined groups received oral gavage at 1/2,1,and 2 × LD50.Retro-orbital blood samples(～500 μL)were collected within 24 hours post-administration and analyzed by UPLC-QE-MS technology.Principal component analysis and orthogonal partial least squares discriminant analysis were used to identify differential metabolites and associated metabolic pathways.Results A total of 387 differential metabolites were identified in the combined poisoning group of diazepam and ethanol implicating the key pathways including tryptophan metabolism,phenylalanine metabolism,arginine and proline metabolism,Glycerophospholipid metabolism,phenylalanine,tyrosine and tryptophan biosynthesis.Conclusion Combined diazepam and ethanol poisoning exerts significant systemic effects by disrupting neurotransmitters conduction,exacerbating oxidative stress response and dysregulating energy metabolism.

Huntington's disease (HD) is an autosomal dominant inherited disease with insidious onset and slow progression, mainly characterized by chorea-like symptom, intelligence decline, and psychiatric abnormalities. Cause of the disease is abnormal expansion of CAG trinucleotide repeat sequences in the first exon of the Huntington gene (HTT) on chromosome 4. Despite the clear etiology, currently, no effective therapeutic measures to control the disease progress is noted, and symptomatic treatment is still the main treatment in clinical practice. This article provides a brief overview of the current clinical trials, clinical challenges, and future development of HD gene therapy to provide references for subsequent related research.

Objective:To explore the characteristics and factors affecting the occurrence of renal injury in patients with abnormal biochemical indexes of renal function after the use of immune checkpoint inhibitors (ICIs), and to provide reference for selection of clinical treatment regimen.Methods:Patients who were treated with immune checkpoint inhibitors researched and developed independently in China including camrelizumab, sintilimab, tislelizumab, and toripalimab from March 1, 2021 to February 28, 2022 and showed estimated glomerular filtration rate (eGFR) <90 ml/(min·1.73 m 2) and/or serum creatinine (Scr)>105 μmol/L were retrieved from the China Hospital Pharmacovigilance System. The clinical data including general information, anti-tumor treatment regimen, laboratory test results, and concomitant medications were collected. Patients were divided into kidney injury group and non-kidney injury group, and all the clinical characteristics were compared between the 2 groups, the influencing factors of kidney injury were analyzed using a binary logistic regression model, the odds ratio ( OR) and its 95% confidence interval ( CI) were calculated. Results:A total of 222 patients were entered in the analysis, including 170 males and 52 females, with a median age of 67 (36, 85) years. Of them, 144 patients were treated with carrilizumab, 38 with sindilizumab, 31 with tirelizumab, and 9 with treprolizumab; 29 patients (13.1%) developed kidney injury, including 26 cases of grade 1 and 3 cases of grade 2 renal injuries; the time of renal injury occurrence was 19-355 days after the first application of ICIs, and the median time was 108 days. After diagnosed of kidney injury, 13 out of 29 patients stopped ICIs, of which 6 had recovered kidney function and 7 had no improvement; 16 patients continued the ICIs treatment, of which 10 patients had recovered or improved kidney function and 6 had no improvement. The clinical characteristics of patients in the 2 groups were compared, and 10 variables including age, gender, baseline renal function, previous use of carboplatin, previous radiotherapy, combined chemotherapy containing cisplatin, combined paclitaxel chemotherapy, combined tyrosine kinase inhibitor (TKI) anti-vascular therapy, combined proton pump inhibitors, and combined radiotherapy were screened for the binary logistic regression analysis. The results showed that female ( OR=3.046, 95% CI: 1.149-8.077), ≤65 years ( OR=3.649, 95% CI: 1.435-9.274), combined TKI anti-vascular therapy ( OR=4.773, 95% CI: 1.496-15.227), and combined radiotherapy ( OR=8.655, 95% CI: 1.268-59.076) were independent risk factors for the development of kidney injury. Conclusions:The incidence of kidney injury in patients with eGFR <90 ml/(min·1.73 m 2) and/or Scr >105 μmol/L after using ICIs is 13.1%. In these patients, female, ≤65 years, combined TKI anti-vascular therapy, and combined radiotherapy may be risk factors for the development of ICI-associated kidney injury.

This review aims to interpret the interventions to improve physical function for children and young people with cerebral palsy, thus providing relevant suggestions.Relevant literatures published before November 2018 were systematically searched in Cochrane library, CINAHL, and Embase MEDLINE using the Grading of Recommendations Assessment, Development and Evaluation method.Consult with international experts and patients to assess evidence and recommend it.Based on 3 systematic reviews, 30 randomized clinical trials, and 5 pre-and post-treatment studies, a total of 13 recommendations were given.The guidelines recommend that, in order to achieve functional stan-dards, intervention measures should include, patient-selected goals, full-task practice in real-life settings, support for family empowerment, and a team approach.The age, ability, and child/family preferences were all needed to be considered.In order to improve walking ability, ground walking and treadmill training can be carried out.Various methods can promote the realization of hand use goals hand use, including the two-hand exercise training, constraint-induced moverment therapy, goal-oriented training and cognitive therapy.In terms of patient self-care, the guideline proposed that, the combination of full-task practice and auxiliary equipment can improve the independence of self-care and reduce the burden of care givers.Leisure goals could be achieved by the combination of the practice of the entire task with strategies to address environmental, personal, and social barriers.The intervention of children and adolescents with cerebral palsy should take into consideration of patient selection and the goal of full-task practice.The child/family preference, age and ability should be considered when clinical workers selecting specific interventions.

Developmental coordination disorder (DCD) is a developmental disorder that mainly affects children′s motor coordination.The prevalence of DCD in childhood is very high, and it seriously affects the physical and mental health of school-age children.In China, this disease has not yet been fully recognized and understood.There is a lack of standardized and unified diagnostic criteria, and the standardization of relevant clinical assessment tools and the establishment of normative models are insufficient.In addition, the clinical practice and experience of most health professionals in dealing with DCD appear to be limited.Based on international clinical practice recommendations on the definition, diagnosis, assessment, intervention, and psychosocial aspects of DCD issued by the European Academy of Childhood Disability in 2019, the recommendations related to the diagnosis, evaluation and intervention of DCD in the guidelines were compiled and interpreted in the light of the current clinical practice and research in China.The objective of this study is to bring DCD to the attention of more domestic medical experts through the interpretation of this international guideline and to provide preliminary guidance on the clinical diagnosis, assessment, and intervention of DCD.
