Alternative splicing (AS), a critical mechanism in gene expression regulation, is essential for cellular physiological processes such as proliferation, metabolism, and apoptosis via generating diverse mRNA isoforms and expanding protein diversity. In the field of oncology, AS has been significantly implicated in the regulation of various biological processes involved in tumorigenesis and cancer progression. Specific mutations or expression changes in splicing factors, such as SF3B1, SRSF2, and U2AF1, play key roles in multiple types of cancer. This review summarizes novel therapeutic strategies for cancer targeting alternative splicing, including inhibiting spliceosome components, antisense oligonucleotide (ASO) therapy, and approaches to overcome drug resistance and immune evasion in cancer. These strategies, which modulate the activity of splicing factors and RNA-modifying enzymes, show promise in addressing chemoresistance and enhancing the efficacy of immunotherapy. This review provides a comprehensive exploration of alternative splicing mechanisms, their role in cancer, and their potential as a therapeutic target, highlighting the importance of alternative splicing in cancer research and therapy.

Objective To explore the effect of the pneumatic and electric hand training system with multiple sensory stimulation mo-dalities combined with low-frequency repetitive transcranial magnetic stimulation on hand movement and tactile pressure sensation in patients with stroke.Methods From May,2023 to October,2024,62 stroke patients from the First Affiliated Hospital of University of South China were randomly divided into control group(n=31)and experimental group(n=31).Both groups received conventional rehabilitation,and 1 Hz low-frequency repetitive transcranial magnetic stimulation in the primary cerebral motor cortex on the unaffected side,while the experimental group received the pneumatic and electric hand training system with multiple sensory stimulation modalities in addition,for four weeks.They were as-sessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),Motor Assessment Scale(MAS),Semmes Weinstein Monofilament Test(SWMT)and modified Barthel index(MBI)before and after treatment.Results One case dropped out in control group and one in the experimental group.After treatment,the scores of FMA-UE,MAS,SWMT and MBI increased in both groups(|t|>5.464,P<0.001),expect the score of SWMT in the control group(P>0.05),and all scores were better in the experimental group than in the control group(|t|>2.195,P<0.05).Conclusion The pneumatic and electric hand training system with multiple sensory stimulation modalities combined with low-frequency repetitive transcranial magnetic stimulation can improve the motor and tactile pressure func-tion of stroke patients,and improve their activity of daily living.

Objective:To evaluate the effect of trans-nasal humidified rapid insufflation ventilatory exchange (THRIVE) on the early postoperative atelectasis in patients undergoing prolonged non-intubated intravenous anesthesia for gastrointestinal endoscopic procedures.Methods:In this randomized double-blind controlled trial, 150 patients of either sex, aged 18-80 yr, with American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ and body mass index of 18-30 kg/m 2, scheduled for endoscopic mucosal resection of multiple colorectal polyps at Northern Jiangsu People′s Hospital Affiliated to Yangzhou University from February 18 to June 15, 2024, were divided into 2 groups ( n=75 each) using simple random allocation: THRIVE group (group T) and conventional oxygen therapy group (group C). In group T, the oxygen flow rate was 10 L/min before anesthesia induction and increased to 50 L/min after induction until the end of operation, and the inhaled oxygen concentration was 100%. Group C used conventional mask oxygen inhalation, with an oxygen flow rate of 10 L/min during anesthesia induction and maintenance. Lung ultrasonography was performed immediately before anesthesia induction and after the end of surgery, and the modified lung ultrasound score and diaphragm mobility during quiet breathing were recorded to assess the occurrence of atelectasis and diaphragmatic dysfunction. The lowest intraoperative SpO 2 value, adverse events during surgery and in the postanesthesia care unit (PACU), duration of PACU stay, adverse events within 7 days after operation, hospitalization duration, and satisfaction scores of both patients and endoscopists were recorded. Results:Compared with group C, the postoperative modified lung ultrasound score and incidence of atelectasis and diaphragmatic dysfunction were significantly decreased, the lowest intraoperative SpO 2 value was increased, the incidence of hypoxemia was decreased, the duration of PACU stay was shortened, and endoscopists′ satisfaction scores were increased ( P<0.05), and no statistically significant changes were observed in diaphragm mobility, incidence of other intraoperative adverse events, incidence of adverse events during PACU stay and within 7 days after operation, or patients′ satisfaction scores in group T ( P>0.05). Conclusions:THRIVE can reduce the risk of early postoperative atelectasis and intraoperative hypoxemia, thereby promoting postoperative recovery of patients undergoing gastrointestinal endoscopy under long-term non-intubated anesthesia.

This study started from the connotation of public welfare and, from the perspective of equal rights and responsibilities, interpreted the public welfare responsibilities and entitlements of hospitals. It developed corresponding quantitative measurement tools and constructed a Public Welfare Rights and Responsibilities Index. Public welfare responsibilities were reflected in the provision of equitable, accessible, appropriate, and reasonable basic medical and public health services. These responsibilities were quantified using the market price of basic medical services, the average cost per case-mix index unit, and public service expenditures. Entitlements were reflected in financial subsidies, tax exemptions, and land policy support. Based on this framework, the study applies the Public Welfare Rights and Responsibilities Index to evaluate 147 public hospitals in City S from 2019 to 2021. The results show that the overall level of public welfare among public hospitals in City S was relatively high (with an average index of 2.39), but showed a slight downward trend. Differences were observed across hospital grades and types, with secondary-level hospitals and general hospitals demonstrating relatively higher levels of public welfare. This study could provide a practical and quantifiable method for measuring hospital public welfare within an equal rights and responsibilities framework, offering a novel analytical tool and empirical evidence to support policy formulation and performance evaluation.

Objective:To evaluate the effectiveness of diaphragm ultrasound in predicting the success of extubation from tracheotomy in patients with acquired brain injury.Methods:A retrospective analysis was conducted on 51 brain-injured patients. They were divided into an extubation failure group and an extubation success group. The results of ultrasound examination of the diaphragm in the 2 groups were analyzed by univariate analysis, and the independent variables with significance were further subjected to multivariate logistic regression analysis. R software was applied to build the diaphragm indicators showing significant predictive power into a histogram model. The predictive value of this nomogram model was assessed using the receiver operating characteristics (ROC) curve.Results:The univariate analysis revealed significant differences between the two groups in terms of diaphragm excursion, diaphragm thickening fraction and diaphragm excursion-time index. The multivariate logistic regression analysis and the nomogram showed that those three variables are independent influencing factors predicting the success of decannulation. The areas under the ROC curves confirmed that finding.Conclusions:Diaphragm excursion, diaphragm thickening fraction and the diaphragm excursion-time index are useful independent predictors of the success of decannulation among brain injury patients.

Objective To investigate the correlation between skeletal muscle fat content and diabetic peripheral neuropathy(DPN)in patients with type 2 diabetes mellitus(T2DM).Methods 290 patients with T2DM admitted to our hospital were enrolled in this study from January 2023 to February 2024 and divided into two groups according to whether they were complicated with DPN:simple T2DM group(T2DM,n=98)and T2DM with DPN group(DPN,n=192).The general data,biochemical indexes and fat distribution indexes measured based on quantitative CT were compared between the two groups.Spearman correlation was used to analyze the relationship between fat distribution indexes and DPN,logistic regression analysis of influencing factors of T2DM complicated with DPN.Results Age,DM duration,WHR,FIns,insulin resistance index(HOMA-IR)and FF were higher in DPN group than in T2DM group(P<0.05).Ca,subcutaneous abdominal fat area(SFA)and liver fat content were lower in DPN group than in T2DM group(P<0.05).Spearman correlation analysis showed that DPN was negatively correlated with SFA and liver fat content(r=-0.127,-0.123,P<0.05),and positively correlated with FF(r=0.117,P<0.05).Logistic regression analysis showed that without adjusting for confounding factors and adjusting for DM duration,WHR,HOMA-IR,Ca,SFA and liver fat content,FF was an influential factor for DPN in T2DM patients.Conclusions Skeletal muscle FF was associated with DPN in patients with T2DM.

Large inter-individual and intra-individual differences in the expression and activity of drug-metabolizing enzymes(DMEs)contribute to unpredictable drug response and toxicity,which is a challenge facing precision medicine.Nuclear receptor-mediated transcriptional regulation and epigenetic mechanisms including histone modifications,non-coding RNAs,and DNA methylation can help to explain the individual variability in DME expressions.However,several questions remain unanswered.Recently,epitranscriptomics,an emerging field,provides new insights into the regulation of gene expression.As the most abundant RNA modification in eukaryotes,N6-methyladenosine(m6A)modifi-cation plays key roles in various physiological and pathological processes.This review summarizes the recent progress in m6A modification-mediated individual variability in DME expression in terms of the role of m6A modification in regulating basal expression of DMEs,crosstalk between m6A modification and nuclear receptors during the ontogeny of DMEs,and the contribution of m6A modification to xenobi-otic exposure-mediated changes in DME expression.This review aims to provide data for the elucida-tion of individual variations in drug metabolism in clinic.

Objective To explore the imaging manifestations of Rosai-Dorfman disease(RDD)in children.Methods A total of 12 children with RDD confirmed by pathology were retrospectively enrolled,including 8 cases underwent non-contrast CT(NCCT)+contrast enhanced CT(CECT),2 cases underwent NCCT+CECT+non-contrast MR(NCMR)+contrast enhanced MR(CEMR),1 case underwent NCCT+NCMR and CEMR,while 1 case underwent NCCT and X-ray examinations.Imaging manifestations of RDD in children were observed.Results Among 12 cases,intranodal type RDD was found in 7 case,extranodal type RDD in 3 cases,and mixed type(with both lymph nodes and extranodal sites affected)RDD were noticed in 2 cases.In 7 cases of intranodal type RDD,NCCT and CECT showed multiple lymph node enlargements in both sides of the neck,with uniform isodensity on NCCT and mild-moderate progressive enhancement in 5 cases,while with low-density necrotic area and ring-shaped enhancement in 2 cases.Among 3 cases of extranodal RDD,the lesion in 1 case involved nasal cavity and posterior group of ethmoid sinuses on CT and MRI,which developed circular soft tissue mass centered on nasal septum with moderate heterogeneous enhancement,also compressed the adjacent bone with destruction.In another case of extranodal RDD,CT showed that the lesion involved left ilium and bilateral parietal bones,with bone destruction accompanied by obvious periosteal reaction and soft tissue mass,which was mildly enhanced.In the rest 1 case of extranodal RDD,CT and X-ray film showed that the lesion involved the upper segment of right femur and left parietal bone,with osteolytic destruction accompanied by layered periosteal reaction.The lesions in both 2 cases of mixed type RDD involved brain(1 case involved left parieto-occipital lobe,1 case involved bilateral temporal lobes,left frontal lobe and bilateral occipital lobes),presented as isodensity on CT and equal or slightly low signal intensity on T 1WI,equal-high mixed signal intensity on T2WI,some shaped like brain gyral with mild edema of surrounding tissue,and nodular or mass-like significant enhancement.RDD involvements of bilateral lung,mediastinum and hilar lymph nodes were also observed in the above 2 cases,chest CT showed multiple nodular or small patchy uniform high-density shadows in bilateral lungs,as well as enlarged mediastinum and hilar lymph nodes.Conclusion Imaging manifestations of pediatric RDD had certain specificity,being helpful to diagnosis.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.
