Given high rates of local-regional control following surgery, a strong rationale exists for the use of adjuvant radiation therapy. Randomized trials have shown superior local control with adjuvant radiotherapy and improved overall survival with adjuvant chemoradiation. The benefit of adjuvant chemoradiation in patients who have undergone D2 lymph node dissection by an experienced surgeon is not known, and the benefit of adjuvant radiation therapy in addition to adjuvant chemotherapy continues to be defined. In unresectable disease, chemoradiation allows long-term survival in a small number of patients and provides effective palliation. Most trials show a benefit to combined modality therapy compared to chemotherapy or radiation therapy alone. The use of pre-operative, intra-operative, 3D conformal, and intensity modulated radiation therapy in gastric cancer is promising but requires further study. The current article reviews the role of radiation therapy in the treatment of resectable and unresectable gastric carcinoma, focusing on current recommendations in the United States.展开更多

文摘The human retina,a complex and highly specialized structure,includes multiple cell types that work synergistically to generate and transmit visual signals.However,genetic predisposition or age-related degeneration can lead to retinal damage that severely impairs vision or causes blindness.Treatment options for retinal diseases are limited,and there is an urgent need for innovative therapeutic strategies.Cell and gene therapies are promising because of the efficacy of delivery systems that transport therapeutic genes to targeted retinal cells.Gene delivery systems hold great promise for treating retinal diseases by enabling the targeted delivery of therapeutic genes to affected cells or by converting endogenous cells into functional ones to facilitate nerve regeneration,potentially restoring vision.This review focuses on two principal categories of gene delivery vectors used in the treatment of retinal diseases:viral and non-viral systems.Viral vectors,including lentiviruses and adeno-associated viruses,exploit the innate ability of viruses to infiltrate cells,which is followed by the introduction of therapeutic genetic material into target cells for gene correction.Lentiviruses can accommodate exogenous genes up to 8 kb in length,but their mechanism of integration into the host genome presents insertion mutation risks.Conversely,adeno-associated viruses are safer,as they exist as episomes in the nucleus,yet their limited packaging capacity constrains their application to a narrower spectrum of diseases,which necessitates the exploration of alternative delivery methods.In parallel,progress has also occurred in the development of novel non-viral delivery systems,particularly those based on liposomal technology.Manipulation of the ratios of hydrophilic and hydrophobic molecules within liposomes and the development of new lipid formulations have led to the creation of advanced non-viral vectors.These innovative systems include solid lipid nanoparticles,polymer nanoparticles,dendrimers,polymeric micelles,and polymeric nanoparticles.Compared with their viral counterparts,non-viral delivery systems offer markedly enhanced loading capacities that enable the direct delivery of nucleic acids,mRNA,or protein molecules into cells.This bypasses the need for DNA transcription and processing,which significantly enhances therapeutic efficiency.Nevertheless,the immunogenic potential and accumulation toxicity associated with non-viral particulate systems necessitates continued optimization to reduce adverse effects in vivo.This review explores the various delivery systems for retinal therapies and retinal nerve regeneration,and details the characteristics,advantages,limitations,and clinical applications of each vector type.By systematically outlining these factors,our goal is to guide the selection of the optimal delivery tool for a specific retinal disease,which will enhance treatment efficacy and improve patient outcomes while paving the way for more effective and targeted therapeutic interventions.

文摘Effective treatment methods for stroke,a common cerebrovascular disease with a high mortality rate,are still being sought.Exosome therapy,a form of acellular therapy,has demonstrated promising efficacy in various diseases in animal models;however,there is currently insufficient evidence to guide the clinical application of exosome in patients with stroke.This article reviews the progress of exosome applications in stroke treatment.It aims to elucidate the significant potential value of exosomes in stroke therapy and provide a reference for their clinical translation.At present,many studies on exosome-based therapies for stroke are actively underway.Regarding preclinical research,exosomes,as bioactive substances with diverse sources,currently favor stem cells as their origin.Due to their high plasticity,exosomes can be effectively modified through various physical,chemical,and genetic engineering methods to enhance their efficacy.In animal models of stroke,exosome therapy can reduce neuroinflammatory responses,alleviate oxidative stress damage,and inhibit programmed cell death.Additionally,exosomes can promote angiogenesis,repair and regenerate damaged white matter fiber bundles,and facilitate the migration and differentiation of neural stem cells,aiding the repair process.We also summarize new directions for the application of exosomes,specifically the exosome intervention through the ventricular-meningeal lymphatic system.The review findings suggest that the treatment paradigm for stroke is poised for transformation.
文摘BACKGROUND Approximately 30%of patients with head and neck cancer experience adverse effects caused by anxiety and depression.Considering the high prevalence,implementing customized interventions to ease adverse emotional states is imperative.AIM To evaluate the efficacy of cognitive behavioral therapy(CBT)-based psychological interventions in improving the psychological well-being and quality of life(QoL)of patients with laryngeal carcinoma.METHODS This study enrolled 120 patients admitted from February 2022 to February 2024.The control group,comprising 50 participants,received standard supportive psychological care,while the research group,consisting 70 participants,underwent CBT-based interventions.Several clinical outcomes were systematically assessed that included postoperative recovery metrics(duration of tracheostomy and nasogastric tube dependence and length of hospitalization),psychological status(Self-Rating Anxiety Scale and Self-Rating Depression Scale),nutritional markers(serum albumin and hemoglobin levels),sleep quality(Self-Rating Scale of Sleep and Athens Insomnia Scale),and QoL(Functional Assessment of Cancer Therapy-Head and Neck).RESULTS The results demonstrated that the research group experienced superior outcomes,with significantly reduced durations of tracheostomy and nasogastric tube dependence,as well as shorter hospital stays,compared with the control group.Additionally,the research group exhibited markedly lower post-intervention Self-Rating Anxiety Scale,Self-Rating Depression Scale,Self-Rating Scale of Sleep,and Athens Insomnia Scale scores,along with minimal but higher change in serum albumin and hemoglobin levels compared with the control group.All five domains of Functional Assessment of Cancer Therapy-Head and Neck showed notable improvements in the research group,exceeding those observed in the control group.CONCLUSION CBT-based psychological support positively affects the mental well-being and QoL of patients with laryngeal carcinoma,highlighting its potential for broader clinical application.
文摘Kidney transplantation(KT)accounts for nearly three-fourths of organ transplants in India,with living donors contributing to 82%of cases.Induction immunosuppression is essential to optimize initial immunosuppression,reduce acute rejections,and enable tailored use of maintenance agents.Rabbit anti-thymocyte globulin(rATG)and interleukin-2 receptor anatagonists(IL-2RA/IL-2RBs)are the most widely used induction therapies.However,data on induction practices across India are limited.To evaluate induction immunosuppression practices across KT centers in India and establish a consensus for different subsets of KT recipients.A nationwide online survey was conducted by the Indian Society of Organ Transplantation(ISOT)among its members(400 KT centers).Responses were analyzed to assess induction practices across diverse donor types,age groups,and immunological risk profiles.Heterogeneity in practices prompted consensus building using a modified Delphi process.Literature review and expert panel discussions(April 2024)were followed by structured voting,and 16 consensus statements were finalized.Of 400 centers approached,254 participated.rATG was the most commonly used induction therapy,followed by IL-2RBs;alemtuzumab was least used.Significant heterogeneity was observed in type,dose,and duration of induction therapy.Consensus recommendations were framed:rATG for high immunological risk recipients and deceased donor KTs;IL-2RB or low-dose rATG for low immunological risk;rituximab in ABOincompatible KTs;and tailoring based on age,diabetes,donor type,infection risk,and affordability.This first ISOT consensus provides 16 India-specific statements on induction therapy in KT.It emphasizes risk-stratified,evidenceinformed,and context-appropriate induction strategies,supporting standardization of care across the country.
文摘A recently published prospective study marks a breakthrough for congenital olfactory disorders in children.The study provides the first long-term,three-year follow-up data,robustly demonstrating the durable efficacy and safety of autologous nasal epithelial stem cell transplantation.This work reveals immense therapeutic potential for a condition traditionally considered untreatable.However,this milestone achievement also presents new challenges.To translate this pioneering therapy from a single-center success to a global standard,multicenter,controlled clinical trials must be initiated immediately.Only through rigorous validation can we ensure its widespread adoption and ultimately bring hope to millions of children worldwide.

文摘AAV-PHP.eB is an artificial adeno-associated virus(AAV)that crosses the blood-brain barrier and targets neurons more efficiently than other AAVs when administered systematically.While AAV-PHP.eB has been used in various disease models,its cellular tropism in cerebrovascular diseases remains unclear.In the present study,we aimed to elucidate the tropism of AAV-PHP.eB for different cell types in the brain in a mouse model of ischemic stroke and evaluate its effectiveness in mediating basic fibroblast growth factor(bFGF)gene therapy.Mice were injected intravenously with AAV-PHP.eB either 14 days prior to(pre-stroke)or 1 day following(post-stroke)transient middle cerebral artery occlusion.Notably,we observed a shift in tropism from neurons to endothelial cells with post-stroke administration of AAV-PHP.eB-mNeonGreen(mNG).This endothelial cell tropism correlated strongly with expression of the endothelial membrane receptor lymphocyte antigen 6 family member A(Ly6A).Furthermore,AAV-PHP.eB-mediated overexpression of bFGF markedly improved neurobehavioral outcomes and promoted long-term neurogenesis and angiogenesis post-ischemic stroke.Our findings underscore the significance of considering potential tropism shifts when utilizing AAV-PHP.eB-mediated gene therapy in neurological diseases and suggest a promising new strategy for bFGF gene therapy in stroke treatment.
文摘The rising prevalence of antibiotic resistance has created a need to reassess the established Helicobacter pylori(H.pylori)eradication protocols,and to develop new ones.Various bacterial and host factors are evaluated,and their contribution to eradication failure is estimated.For a long time being considered the cornerstone eradication scheme,the standard triple therapy has been replaced with novel,more efficient regimens,namely sequential and concomitant,along with the emergence of a new design of bismuth quadruple therapy.A rescue levofloxacin based regimen has overcome the fear of therapy failure due to higher prevalence of dual resistant(clarithromycin and metronidazole)H.pylori.Culture-free and efficient susceptibility test are reestablishing the concept of tailored therapy,making eradication success close to originally desirable rates.Alleviating therapy side effects and improving patient compliance are as important as choosing appropriate eradication schemes,so various probiotic compound supplements are taken into consideration.Finally,we summarize the emerging efforts and obstacles in creating efficientH.pylori vaccine.
文摘Gastric cancer,a prevalent malignancy worldwide,ranks sixth in terms of frequency and third in fatality,causing over a million new cases and 769000 annual deaths.Predominant in Eastern Europe and Eastern Asia,risk factors include family medical history,dietary habits,tobacco use,Helicobacter pylori,and Epstein-Barr virus infections.Unfortunately,gastric cancer is often diagnosed at an advanced stage,leading to a grim prognosis,with a 5-year overall survival rate below 5%.Surgical intervention,particularly with D2 Lymphadenectomy,is the mainstay for early-stage cases but offers limited success.For advanced cases,the National Comprehensive Cancer Network recommends chemotherapy,radiation,and targeted therapy.Emerging immunotherapy presents promise,especially for unresectable or metastatic cases,with strategies like immune checkpoint inhibitors,tumor vaccines,adoptive immunotherapy,and nonspecific immunomodulators.In this Editorial,with regards to the article“Advances and key focus areas in gastric cancer immunotherapy:A comprehensive scientometric and clinical trial review”,we address the advances in the field of immunotherapy in gastric cancer and its future prospects.

文摘Synergistic therapy using multiple modalities is a highly promising therapeutic strategy.Near-infrared-Ⅱ(NIR-Ⅱ)fluorescence imaging,with its deep penetration and high fidelity,has frequently been employed in the literature to guide and assist treatment.Herein,we report the development of a NIR-Ⅱfluorescence imaging guided multi-therapy platform PDI-DS NPs,which integrates a novel activatable phototheranostic agent PDI-DBU,a H_(2)S donor DPS and an amphiphilic polymer DSPE-m PEG2000.In order to maximize redshift of absorption and emission of PDI derivatives,we introduced an electron donating group DBU on PDI to obtain PDI-DBU.PDI-DBU exhibits a distinct absorption band at 700-900 nm and demonstrates excellent NIR-Ⅱfluorescence emission/imaging properties and good photothermal effects under 808 nm laser irradiation.More importantly,under 808 nm laser irradiation,PDI-DBU could be oxidized,and the photodynamic effect of the material could be subsequently activated under 530 nm laser irradiation,achieving the combination of photothermal and activatable photodynamic dual modality treatment.The H_(2)S donor DPS,when triggered by the abundant glutathione(GSH)within the tumor microenvironment(TME),is capable of generating H_(2)S.On one hand,H_(2)S can inhibit tumor growth by disrupting mitochondrial function,on the other hand,it can also repress the expression of heat shock protein 90(HSP90),thereby reversing tumor cell resistance mechanism against photothermal therapy.The utilization of PDI-DS NPs combined with DPS for efficient tumor ablation has been successfully demonstrated both in vitro and in vivo.This synergistic therapeutic platform thus offers a promising strategy in the field of NIR-Ⅱfluorescence imaging guided tumor therapy.

文摘Hepatocellular carcinoma(HCC)is a lethalmalignancy.Formany years,chemotherapeutic regimens have served as the foundation of sys-temic therapies for advanced HCCdespite their limited efficacy and significant adverse effects.In recent decades,novel systemic therapies such as immunotherapy and targeted therapy have profoundly transformed HCC management.Although some patients with advanced HCC exhibit dramatically improved outcomes,the efficacy of immunotherapy and targeted therapy,either asmonotherapy or in combina-tion,remains limited.Numerous trials have indicated that locoregional therapies,including transarterial chemoembolization(TACE),hepatic arterial infusion chemotherapy(HAIC),and transarterial radioembolization(TARE),may synergize with systemic therapies to enhance ad-vanced HCC treatment.However,further studies are required to optimize these combination regimens.In contrast,curative treatments,such as surgical resection,liver transplantation,or local ablation,are typically recommended for patients with early-stage HCC.Although these treatments have achieved an impressivemedian overall survival(OS)exceeding 60months,more than half of the patients experience recurrence within 5 years.Consequently,the development of effective perioperative neoadjuvant or adjuvant therapies is urgently needed to reduce the incidence of recurrence and metastasis.It provides a comprehensive overview of recent advances in systemic therapies for advanced HCC,as well as adjuvant or neoadjuvant immunotherapies for early HCC.Additionally,emerging clinical trials and trial designs for future investigations into systemic therapies for HCC management are critically analyzed.

文摘Conventional therapies are primary cancer treatments that directly eliminate or inhibit the growth of tumor cells,reducing the overall tumor burden.Increasing evidence suggests that conventional therapies possess significant immunomodulatory properties in addition to their established direct tumoricidal effects.Emerging immunotherapies have revolutionized the clinical management of various cancer types.Conventional therapy and immunotherapy have demonstrated remarkable clinical efficacy,leading to numerous ongoing clinical investiga-tions exploring their potential synergistic effects.However,trials investigating the combination of conventional therapy and immunotherapy have shown limited synergistic therapeutic efficacy.This unsatisfactory clinical outcome may be attributed to the suboptimal design of the combination approach and the inadequate understanding of the mechanisms and impacts of radiotherapy,chemotherapy,targeted ther-apy regimens(including dosing,timing,and administration route),and surgery on both cancer cells and the host immune system.Here,we comprehensively review preclinical and clinical investigations exploring the therapeutic effects and mechanisms of conventional therapy alone or in combination with immunotherapy.We proposed that optimizing the dosing,timing,and route of administration of conventional therapies can enhance the synergistic efficacy of combination therapies,thus offering significant clinical advantages.
文摘Outcomes in patients with gastric cancer in the United States remain disappointing, with a five-year overall survival rate of approximately 23%. Given high rates of local-regional control following surgery, a strong rationale exists for the use of adjuvant radiation therapy. Randomized trials have shown superior local control with adjuvant radiotherapy and improved overall survival with adjuvant chemoradiation. The benefit of adjuvant chemoradiation in patients who have undergone D2 lymph node dissection by an experienced surgeon is not known, and the benefit of adjuvant radiation therapy in addition to adjuvant chemotherapy continues to be defined. In unresectable disease, chemoradiation allows long-term survival in a small number of patients and provides effective palliation. Most trials show a benefit to combined modality therapy compared to chemotherapy or radiation therapy alone. The use of pre-operative, intra-operative, 3D conformal, and intensity modulated radiation therapy in gastric cancer is promising but requires further study. The current article reviews the role of radiation therapy in the treatment of resectable and unresectable gastric carcinoma, focusing on current recommendations in the United States.
