Objective To summarize and analyze the efficacy and influencing factors of second allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute leukemia relapsing after the first allo-HSCT. Methods Clinical data of 17 patients with acute leukemia who underwent second allo-HSCT at Peking University First Hospital from January 2005 to December 2024 were retrospectively analyzed. Results Among the 17 patients, 7 achieved long-term disease-free survival after second transplantation. The median progression-free survival after successful second transplantation was 7 months (range 8 days to 69 months). The relapse fatality was 24%, and the transplant-related fatality was 35%. Conclusions Second transplantation is an effective treatment for relapsed and refractory acute leukemia, but the relapse fatality and transplant-related fatality remain high. Patient age, time of relapse after the first transplantation and disease status before second transplantation are all factors that affect the efficacy of second transplantation. Younger age, late relapse and complete remission of disease before second transplantation are all beneficial for long-term disease-free survival after second transplantation.

Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

Traditional Chinese medicine （TCM） clinical trials face challenges such as low participant compliance， insufficient geographical coverage， and cost-effectiveness imbalances. Decentralized clinical trials （DCT）， enabled by digital technology for remote data collection and monitoring， offer a new direction for TCM clinical trial research. This article systematically reviews three novel clinical trial design models. Combining the holistic concept and indivi-dualized treatment characteristics of TCM， it analyzes the challenges currently faced in TCM DCT practice， including the digitization and standardization of TCM theory， data security， privacy protection and patient engagement difficu-lties， insufficient ethical review and regulatory system adaptation， inadequate personnel training， and a shortage of interdisciplinary talent. Addressing these challenges， the article proposes methodological recommendations for DCT implementation that align with the principles of TCM diagnosis and treatment. These recommendations include promoting the intelligentization and standardization of TCM practices， constructing a full-chain data security and privacy protection system， improving the ethical framework and clarifying regulatory responsibilities， and cultivating and building interdisciplinary talent and capabilities， which provide theoretical and technical references for establishing standardized DCT practices in TCM.

BackgroundAdverse childhood experiences （ACEs） are strong predictors of psychopathology across the lifespan， exerting extensive adverse effects on physical and mental health during early development. While ACEs increase the risk of childhood psychopathology， sleep quality and impair cognitive function， the early neurobiological mechanisms mediating ACE-induced cognitive impairment remain unclear. ObjectiveTo explore the association between ACEs exposure and the risk of psychopathology， sleep disorders， and cognitive function， and to examine the mediating role of the putamen volume in the relationship between ACEs and cognitive function from a neurodevelopment perspective. MethodsData were obtained from the Adolescent Brain Cognitive Development （ABCD） study， comprising 10 572 children aged 9 to 10. Participants were categorized into five groups based on the cumulative score of ACEs reported by their parents and the children themselves： no-exposure group （0 types of ACEs）， the one-exposure group， the two-exposure group， the three-exposure group， and the high-risk exposure group （≥ 4 types of ACEs）. Logistic regression analysis was employed to evaluate the association between ACEs and psychopathological symptoms ［T score of the Child Behavior Checklist （CBCL） ≥ 65］. Multiple linear regression analysis was ultilized to analyze the correlations between ACEs and the scores of the Sleep Disturbance Scale for Children （SDSC）， the NIH Toolbox Cognition Battery （NIHTB-CB）， as well as the multiple structures in the cerebral cortex and subcortex. The Bootstrap method was applied to test the mediating effect of the putamen volume between ACEs and neurocognitive function. ResultsAfter adjusting for confounders， ACEs cumulative score was correlated with children's psychopathological symptoms in a dose-response manner. Compared with the no-exposed group， the high-risk exposure group had a 2.08-fold （OR=2.080， 95% CI： 1.401–3.088） increased risk of internalizing problems and a 3.13-fold （OR=3.132， 95% CI： 1.703–5.760） increased risk of externalizing problems， and the risk of conduct problems was 4.68 times that of the no-exposed group （OR=4.681， 95% CI： 2.528–8.669）. ACEs cumulative score positively predicted the total score of SDSC （β=0.080， 95% CI： 0.059–0.102）， with relatively stronger predictive effects on sleep-wake transition disorder （β=0.086， 95% CI： 0.063–0.109） and sleep onset and maintenance disorder （β=0.066， 95% CI： 0.043–0.089）. In terms of neurocognition and brain structure， ACEs cumulative score negatively predicted the overall cognitive composite score （β=-0.025， 95% CI： -0.050–-0.001）， the crystallized cognitive composite score （β=-0.035， 95% CI： -0.060–-0.010）， the volume of the left putamen nucleus （β=-0.025， 95% CI： -0.046– 0.003）， and the volume of the right putamen nucleus （β=-0.023， 95% CI： -0.044– 0.003）. The total putamen volume played a partial mediating role between ACEs and the overall cognitive composite score， the effect value was -0.002 （95% CI： -0.004–-0.001）， accounting for 7.49% of the total effect. ConclusionACEs exposure may increase the risk of psychopathological and sleep disturbances in children and may impair neurocognitive function. Reduced putamen volume may serve a potential neurobiological pathway underlying the impact of ACEs on childhood cognition. ［Funded by National Natural Science Foundation of China-Young Scientists Program （number， 82401763）； Sichuan University West China Hospital Full-time Postdoctoral Research and Development Fund Project （number， 2023HXBH084）］

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

Objective:To investigate the clinical effect of near-infrared autofluorescence (NIRAF) imaging combined with nano-carbon in the identification of parathyroid gland.Methods:A total of 80 patients with thyroid cancer requiring bilateral thyroidectomy plus single/bilateral central area lymphatic dissection were prospectively enrolled in the Department of Thyroid and Breast Surgery of the Shenzhen Third People′s Hospital from January 2020 to June 2023. Two groups were divided in order of time of admission. In the combined group (40 cases), the parathyroid glands were identified by NIRAF+ nano-carbon negative imaging. The nano-carbon group (40 cases) was negatively developed with nano-carbon alone. The detection rate and accuracy of parathyroid gland and the changes of parathyroid hormone (1 d and 6 months after operation) were compared between the two groups.Results:There was no significant difference in the detection rate of parathyroid glands between the two groups ( P=0.65), and the accuracy rate in the combined group was higher than that in the nano-carbon group, the difference was statistically significant (χ 2=8.79, P=0.003). The level of parathyroid hormone in the combined group was higher than that in the nano-carbon group 1 day after surgery, and the difference was statistically significant ( Z=-1.19, P=0.03). There was no significant difference in parathyroid hormone levels between the two groups 6 months after operation ( P=0.18). Conclusions:NIRAF imaging combined with nano-carbon negative imaging can improve the accuracy of intraoperative parathyroid identification, and may reduce the incidence of temporary postoperative hypoparathyroidism.

This article reports a postcraniotomy patient with renal insufficiency and electrolyte imbalance who developed ventilator-associated pneumonia caused by extensively drug-resistant Klebsiella pneumoniae.According to the patient's pathophysiological characteristics,bacterial epidemiological characteristics,and bacterial culture results,combined with the latest guidelines and the pharmacokinetic/pharmacodynamic characteristics of antibiotics,a full-dose ceftazidime/avibactam regimen was initially suggested by the clinical pharmacist,and which was adopted by doctor.When the effect of ceftazidime/avibactam was poor and no guideline-recommended alternatives were available,the clinical pharmacist,in conjunction with clinical experience,proposed a combination therapy of colistin sulfate and tigecycline,with the implementation of adverse reaction monitoring and mucin sulfate blood concentration monitoring.Finally,the pneumonia was effectively controlled,the inflammatory indicators such as temperature and the white blood cell count returned to normal,no adverse drug reactions occurred,and the patient was successfully transferred to the rehabilitation institution.Clinical pharmacists stay updated on the latest medication knowledge both domestically and internationally,recommend advanced drug treatment protocols for clinical practice,assist in managing severe infections,and play an important role in the clinical team.

This study systematically analyzed the clinical applications of photobiomodulation(PBM)therapy in Parkinson disease(PD)patients using a scoping review methodology,with the aim of summarizing treatment protocols,outcome measures,and therapeutic effects to provide references for subsequent clinical research and treatment.A comprehensive search was conducted across Web of Science,PubMed,Embase,Cochrane Library,CNKI,and Wanfang,ultimately including 13 studies.The results indicate that PBM therapy can effectively improve motor symptoms,non-motor symptoms,and brain structure in PD patients,serving as a beneficial supplement to conventional treatments.However,there remains a scarcity of large-sample randomized controlled trials(RCTs),along with significant variations in the selected treatment parameters.Therefore,further investigations with larger sample sizes and extended durations are required to validate its therapeutic efficacy.
