OBJECTIVE: To analyze the factors associated with mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with severe aplastic anemia (SAA). METHODS: The clinical data of 90 children with SAA who received allo-HSCT in the Department of Hematology, Wuhan Children's Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from August 2016 to July 2023 were collected. The clinical features and causes of death were analyzed retrospectively. Cox proportional hazards model was used to screen the risk factors of death. RESULTS: Only 9 children died with a median time of 6.3(2.6, 8.3) months among the 90 children with SAA after allo-HSCT. Among the 5 deaths due to infection, 3 were pulmonary infection, including 2 cases of cytomegalovirus pneumonia. One case developed septic shock due to gastrointestinal infection. One case experienced graft failure, which was complicated by bloodstream infection, and developed septic shock. Three cases died of transplantation-associated thrombotic microangiopathy (TA-TMA). One case died of gastrointestinal graft-versus-host disease (GVHD). The results of multivariate analysis showed that post-transplant +60 d PLT≤30×10⁹/L (HR=7.478, 95%CI : 1.177-47.527, P =0.033), aGVHD Ⅲ-Ⅳ (HR=7.991, 95%CI : 1.086-58.810, P =0.041), and TA-TMA occurrence (HR=13.699, 95%CI : 2.146-87.457, P =0.006) were independent risk factors for post-transplant mortality. CONCLUSION Allo-HSCT is an effective therapy for SAA in children. Post-transplant +60 d PLT≤30×10⁹/L, aGVHD Ⅲ-Ⅳ, and TA-TMA occurrence are independently associated with post-transplant mortality, which may be helpful for early detection of potential high-risk children and optimization of clinical diagnostic and treatment strategies.

Objective:To compare the effects of intermittent oro-esophageal tube feeding (IOE) and nasogastric tube feeding (NGT) on nutritional status, complications, swallowing function and airway protection in persons with post-stroke dysphagia (PSD).Methods:Sixty PSD patients were randomized into an observation group ( n=30) and a control group ( n=30). In addition to conventional medication and swallowing rehabilitation, the observation group received supplemental IOE nutrition, while the control group was given NGT. Before and after one month, both groups were evaluated using the Functional Oral Intake Scale (FOIS), and such nutritional indicators as body mass index (BMI), hemoglobin (Hb) levels, albumin (ALB), prealbumin (PAB), skinfold at the triceps (TSF) and arm muscle circumference (AMC) were measured. The morphology of each subject′s epiglottis, any edema of the arytenoid mucosa and vocal cord mobility were assessed using fiberoptic endoscopic evaluation of swallowing (FEES). Murray Secretion Scale ratings were documented, along with laryngeal sensation during swallowing, swallowing reflex, the Yale Pharyngeal Residue Severity Rating Scale, and the Rosenbek Penetration-aspiration Scale. Results:Both groups showed significant improvement in their average FOIS scores and all of the nutritional descriptors, but with significantly greater improvement in the observation group. Abnormalities in the shape of the epiglottis, arytenoid edema and vocal cord mobility had decreased significantly in both groups. This was also true of larynx sensation, swallowing reflex, pharyngeal secretions, residue and penetration/aspiration. On average the improvements were significantly greater in the observation group.Conclusion:Compared with NGT, IOE more effectively improves swallowing, enhances airway functioning and reduces NGT syndrome among PSD patients. These observations support its clinical adoption.

Aim To investigate the effect of oroxylin A(OA)on apoptosis in Ishikawa cell line of endometrial cancer and the underlying mechanism through the phosphatidylinositol-3 kinase/protein kinase B(PI3K/AKT)signaling pathway.Methods Ishikawa cells were treated with different concentrations of OA(0,4,8,10,12,and 20 μmol·L-1)for 24 h-72 h,the cell viability was detected by CCK-8 assay,apoptosis was detected by flow cytometry,and the protein ex-pression levels of B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),PI3K/AKT,recombinant cytochrome P450 1B1(CYP1B1),and catechol-O-methyltransferase(COMT)were detected by Western blot technique.Results OA inhibited the prolifera-tion of Ishikawa cells in a concentration-and time-de-pendent manner.Compared with the blank control group,the expression of Bax protein increased signifi-cantly,while the expression of Bcl-2 protein decreased significantly with the increase of OA concentration.The expression of COMT protein increased significant-ly,while the expression of CYP1B1 protein decreased significantly.PI3K/AKT:IGF-1(PI3 K agonist)sup-plementation reversed the effect,the expression of COMT protein significantly decreased,and the expres-sion of CYP1B1 protein significantly increased.Con-clusions OA exerts anti-tumor effects in Ishikawa cells of endometrial cancer,which may be related to cell apoptosis mediated by the inhibition of the PI3K/AKT signaling pathway.

This study aims to integrate data mining techniques of single cell transcriptomics and spatial transcriptomics, along with animal experiment validation, so as to systematically characterize the protective effects of Jianpi Tongluo Formula(JTF) on the cartilage in knee osteoarthritis(KOA) and elucidate the underlying molecular mechanisms. Single cell transcriptomics and spatial transcriptomics datasets(GSE254844 and GSE255460) of the cartilage tissue obtained from KOA patients were analyzed to map the single cell-spatial heterogeneity and identify key pathogenic factors. After that, a KOA rat model was established via knee joint injection of papain. The intervention effects of JTF on the expression features of these key factors were assessed through real-time quantitative polymerase chain reaction(PCR), Western blot, and immunohistochemical staining. As a result, the integrated single cell and spatial transcriptomics data identified distinct cell subsets with different pathological changes in different regions of the inflamed cartilage tissue in KOA, and their differentiation trajectories were closely related to the inflammatory fibrosis-like pathological changes of chondrocytes. Accordingly, the expression levels of the two key effect targets, namely nuclear receptor coactivator 4(NCOA4) and high mobility group box 1(HMGB1) were significantly reduced in the articular surface and superficial zone of the inflamed joints when JTF effectively alleviated various pathological changes in KOA rats, thus reversing the abnormal chondrocyte autophagy level, relieving the inflammatory responses and fibrosis-like pathological changes, and promoting the repair of chondrocyte function. Collectively, this study revealed the heterogeneous characteristics and dynamic changes of inflamed cartilage tissue in different regions and different cell subsets in KOA patients. It is worth noting that NCOA4 and HMGB1 were crucial in regulating chondrocyte autophagy and inflammatory reaction, while JTF could reverse the regulation of NCOA4 and HMGB1 and correct the abnormal molecular signal axis in the target cells of the inflamed joints. The research can provide a new research idea and scientific basis for developing a personalized therapeutic schedule targeting the spatiotemporal heterogeneity characteristics of KOA.

Objective To evaluate the forensic application value of used dental floss as a source of bio-logical evidence for individual identification by analyzing the effects of dental floss sample collection methods,DNA extraction methods,preservation conditions,and sampling sites on the success rate of STR typing.Methods Dental floss samples were collected using three techniques:direct cutting,cotton swab wiping,and flocked swab wiping,respectively.DNA was extracted respectively by the Chelex,spin column-based and magnetic bead-based methods.DNA quantification and STR typing were per-formed using the Qubit kit and FGI HumDNA Typing kit(Platinum),respectively.Storage environ-ments(temperature and humidity,ultraviolet radiation)and sampling locations(the floss part,the handle part)on DNA quantity and STR typing were evaluated.Results Through conducting a statisti-cal analysis of three key indicators of average DNA mass concentration,STR locus detection rate,and typing accuracy rate,the direct cutting method demonstrated the highest efficacy,followed by cotton swab wiping mothed,and the flocked swab wiping method had the lowest efficacy.Direct cutting yielded an average DNA mass concentration greater than(4.94±1.87)ng/μL,with STR locus detection and accuracy rates of 100%.Bead-based DNA extraction method produced superior DNA concentration and quality compared to spin column-based and Chelex methods,regardless of whether the sampling technique used.Preservation conditions had a significant impact on the DNA analysis of samples.Par-ticularly,the STR typing accuracy of samples preserved at 55℃/50%RH for 35 days dropped to(81.82±12.31)%,and that of samples exposed to ultraviolet radiation for 12 h dropped to(55.46±34.31)%.DNA concentration from the handle part of dental floss was extremely low,with an STR typing accuracy of only(30.91±27.35)%.Conclusion Using cotton swabs to wipe or directly cutting the thread of dental floss samples,and combining this approach with the magnetic bead method for DNA extraction,can best guarantee the concentration and quality of DNA.In addition,samples should be stored in low-temperature,low-humidity environment,protected from light and ultraviolet radiation.

Objective To explore the effectiveness of drawing-based method in medical courses and their impact on students' learning habits,academic performance,and comprehensive competencies,in order to meet the demand for high-quality,interdisciplinary,and innovative talent,and provide theoretical support for integrating aesthetic education into medical training.Methods A questionnaire survey was conducted among medical students(n=310)at Dalian Medical University,covering the frequency of using drawing method and their effects on learning outcomes,innovation ability,and humanistic qualities.Data were analyzed using the Chi-square test and Fisher's exact test(P＜0.05).Results Totally 93.6％of students approved of using drawing method for learning medical courses,with 70.8％having developed a habit of drawing-based learning.Students with stronger drawing skills were more inclined to use drawing method and supported their application in teaching.The frequency of drawing-based learning was positively correlated with anatomy scores(P＜0.05).Students generally agreed that drawing method enhanced knowledge comprehension,learning interest,long-term memory,innovation ability,critical thinking,and humanistic qualities.However,students with weaker drawing skills perceived drawing method as potentially increasing learning burdens and being less efficient,but this perception significantly decreased with increased drawing frequency(P＜0.05).Conclusion Drawing methods are widely used in medical courses and effectively improve learning outcomes and comprehensive competencies.Drawing proficiency and frequency are key factors influencing students' acceptance and learning effectiveness.Future efforts should focus on promoting drawing method,strengthening students' drawing skills,and optimizing learning processes to deepen the integration of aesthetic education in medical training.

OBJECTIVE: Aloin, the main active component in Aloe vera (L.) Burm. f., has shown promising anti-tumor effects. This study investigated the impact of aloin in lung squamous cell carcinoma (LUSC) and explored its functional mechanism. METHODS: We analyzed the viability, migration, invasion, proliferation, and apoptosis of two LUSC cell lines after treatment with aloin. Target molecules of aloin and downstream target transcripts of nuclear receptor subfamily 3 group C member 2 (NR3C2) were predicted by bioinformatics. The biological functions of NR3C2 and metallothionein 1 M (MT1M) in the malignant properties of LUSC cells were determined. A co-culture system of LUSC cells with monocyte-derived macrophages was constructed. Mouse xenograft tumor models were generated to analyze the functions of aloin and NR3C2 in the tumorigenic activity of LUSC cells and macrophage polarization in vivo. RESULTS: Aloin suppressed malignant properties of LUSC cells in vitro. However, these effects were negated by the silencing of NR3C2. NR3C2 was found to activate MT1M transcription by binding to its promoter. Additional upregulation of MT1M suppressed the malignant behavior of LUSC cells augmented by NR3C2 silencing. Analysis of the M1 and M2 markers/cytokines in the macrophages or the culture supernatant revealed that aloin treatment or MT1M overexpression in LUSC cells enhanced M1 polarization while suppressing M2 polarization of macrophages, whereas NR3C2 silencing led to reverse trends. Consistent findings were reproduced in vivo. CONCLUSION This study demonstrated that aloin activates the NR3C2/MT1M axis to suppress the malignant behavior of LUSC cells and M2 macrophage polarization.

Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia （FD）， this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes， postprandial distress syndrome （PDS） and epigastric pain syndrome （EPS）. The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS， whereas local acupoints alone may be more suitable for EPS. Additionally， the study explores the impact of various factors， such as stimulation techniques， needling order， intensity or stimulation parameters， and depth， on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations， local versus distal， affect the treatment outcomes of FD subtypes， providing new insights for clinical acupuncture prescriptions.

Objective:To compare the types and contents of trace elements in compound trace element preparations used in parenteral nutrition in Beijing against the doses recommended by the guidelines, so as to facilitate optimal choice of preparations for different populations in clinical practice.Methods:The available compound trace element preparations were determined according to the drug list from the Medical Insurance Recruitment and Procurement System of Beijing and the recommended doses of trace elements in the guidelines released by Chinese domestic and foreign nutrition societies were collected and compared.Results:The compound trace element preparations used in Beijing comprised 4 varieties and 6 specifications, with the daily cost ranging from 11.32 to 471 Chinese Yuan. There were 3 varieties of trace element preparations for adults, including multi-trace elements injection (Ⅱ), multi-trace elements injection (Ⅲ), and multi-trace elements injection. Among those, multi-trace elements injection (Ⅲ) met the guideline recommendations best and the price was moderate. For pediatric populations, multi-trace elements injections (Ⅰ) satisfied better the trace element requirements for preterm infants and infants from term to 3 months, while multi-trace elements injections (Ⅲ) outperformed in meeting the trace element requirements for 3-to-12-month infants and children. However, there were still some differences in the trace element contents between the two preparations and the guideline recommendations.Conclusion:The currently available varieties and specifications of trace element preparations basically meet the recommendations of evidence-based guidelines, but there is still the need to improve the instructions for and evidence on the pediatric application of certain preparations.
