Adjuvant therapy for hepatocellular carcinoma:Dilemmas at the start of a new era

Approximately 50%-70%of patients with hepatocellular carcinoma experience recurrence within five years after curative hepatic resection or ablation.As a result,many patients receive adjuvant therapy after curative resection or ablation in order to prolong recurrence-free survival.The therapy recommended by national guidelines can differ,and guidelines do not specify when to initiate adjuvant therapy or how long to continue it.These and other unanswered questions around adjuvant therapies make it difficult to optimize them and determine which may be more appropriate for a given type of patient.These questions need to be addressed by clinicians and researchers.

Synergistic chemotherapy/PTT/oxygen enrichment by multifunctional liposomal polydopamine nanoparticles for rheumatoid arthritis treatment

Amultifunctional liposomal polydopamine nanoparticle(MPM@Lipo)was designed in this study,to combine chemotherapy,photothermal therapy(PTT)and oxygen enrichment to clear hyperproliferating inflammatory cells and improve the hypoxic microenvironment for rheumatoid arthritis(RA)treatment.MPM@Lipo significantly scavenged intracellular reactive oxygen species and relieved joint hypoxia,thus contributing to the repolarization of M1 macrophages into M2 phenotype.Furthermore,MPM@Lipo could accumulate at inflammatory joints,inhibit the production of inflammatory factors,and protect cartilage in vivo,effectively alleviating RA progression in a rat adjuvant-induced arthritis model.Moreover,upon laser irradiation,MPM@Lipo can elevate the temperature to not only significantly obliterate excessively proliferating inflammatory cells but also accelerate the production of methotrexate and oxygen,resulting in excellent RA treatment effects.Overall,the use of synergistic chemotherapy/PTT/oxygen enrichment therapy to treat RA is a powerful potential strategy.

Efficacy and safety of targeted therapy plus immunotherapy combined with hepatic artery infusion chemotherapy (FOLFOX) for unresectable hepatocarcinoma

BACKGROUND The advent of cutting-edge systemic therapies has driven advances in the treatment of hepatocellular carcinoma(HCC),and therapeutic strategies with multiple modes of delivery have been shown to be more efficacious than mono-therapy.However,the mechanisms underlying this innovative treatment modality have not been elucidated.AIM To evaluate the clinical efficacy of targeted therapy plus immunotherapy combined with hepatic arterial infusion chemotherapy(HAIC)of FOLFOX in patients with unresectable HCC.METHODS We enrolled 53 patients with unresectable HCC who received a combination of targeted therapy,immunotherapy,and HAIC of FOLFOX between December 2020 and June 2021 and assessed the efficacy and safety of the treatment regimen.RESULTS The objective response rate was 60.4%(32/53),complete response was 24.5%(13/53),partial response was 35.9%(19/53),and stable disease was 39.6%(21/53).The median duration of response and median progression-free survival were 9.1 and 13.9 months,respectively.The surgical conversion rate was 34.0%(18/53),and 1-year overall survival was 83.0%without critical complicating diseases or adverse events(AEs).CONCLUSION The regimen of HAIC of FOLFOX,targeted therapy,and immunotherapy was curative for patients with unresectable HCC,with no serious AEs and a high rate of surgical conversion.

Transarterial embolization is an acceptable bridging therapy to hepatocellular carcinoma prior to liver transplantation

BACKGROUND Hepatocellular carcinoma(HCC)is an aggressive malignant neoplasm that requires liver transplantation(LT).Despite patients with HCC being prioritized by most organ allocation systems worldwide,they still have to wait for long periods.Locoregional therapies(LRTs)are employed as bridging therapies in patients with HCC awaiting LT.Although largely used in the past,transarterial embolization(TAE)has been replaced by transarterial chemoembolization(TACE).However,the superiority of TACE over TAE has not been consistently shown in the literature.AIM To compare the outcomes of TACE and TAE in patients with HCC awaiting LT.METHODS All consecutive patients with HCC awaiting LT between 2011 and 2020 at a single center were included.All patients underwent LRT with either TACE or TAE.Some patients also underwent percutaneous ethanol injection(PEI),concom-itantly or in different treatment sessions.The choice of LRT for each HCC nodule was determined by a multidisciplinary consensus.The primary outcome was waitlist dropout due to tumor progression,and the secondary outcome was the occurrence of adverse events.In the subset of patients who underwent LT,complete pathological response and post-transplant recurrence-free survival were also assessed.RESULTS Twelve(18.5%)patients in the TACE group(only TACE and TACE+PEI;n=65)and 3(7.9%)patients in the TAE group(only TAE and TAE+PEI;n=38)dropped out of the waitlist due to tumor progression(P log-rank test=0.29).Adverse events occurred in 8(12.3%)and 2(5.3%)patients in the TACE and TAE groups,respectively(P=0.316).Forty-eight(73.8%)of the 65 patients in the TACE group and 29(76.3%)of the 38 patients in the TAE group underwent LT(P=0.818).Among these patients,complete pathological response was detected in 7(14.6%)and 9(31%)patients in the TACE and TAE groups,respectively(P=0.145).Post-LT,HCC recurred in 9(18.8%)and 4(13.8%)patients in the TACE and TAE groups,respectively(P=0.756).Posttransplant recurrence-free survival was similar between the groups(P log-rank test=0.71).CONCLUSION Dropout rates and posttransplant recurrence-free survival of TAE were similar to those of TACE in patients with HCC.Our study reinforces the hypothesis that TACE is not superior to TAE as a bridging therapy to LT in patients with HCC.

Clinical Study on Improving Articulation Clarity in Spastic Cerebral Palsy with 120 Cases of Oral-Facial Acupressure Combined with Oral Placement Therapy

Objective:To observe the efficacy of oral-facial acupressure combined with oral placement therapy(OPT)in improving articulation clarity in 120 children with spastic cerebral palsy,and to explore effective therapeutic solutions for speech disorders associated with spastic cerebral palsy.Methods:A total of 120 children with spastic cerebral palsy and speech disorders,meeting the inclusion criteria,were randomly assigned into two groups:60 cases in the treatment group and 60 cases in the control group.The treatment group received orofacial acupressure combined with OPT,while the control group received only OPT.The Oral Motor Function Assessment Scale(OMFAS),developed by the China Rehabilitation Research Centre(CRRC),was used to evaluate the treatment outcomes before and after the intervention.Results:After the treatment,both the treatment and control groups showed improved mobility of the mandible,lips,and tongue.However,the treatment group exhibited significantly better improvement than the control group,with the difference between the two groups being statistically significant(P<0.05).Conclusion:Oral-facial acupressure combined with OPT can effectively improve articulation clarity in children with spastic cerebral palsy.This combined therapy is recommended for clinical promotion and application.

“liberal arts”的源与流——古今之变中的审视

“古今之变”是审视liberal arts流变的中心线索。古典liberal arts是具有内在统一性并指向完满品格的整全性知识体系。欧洲三次文艺复兴对liberal arts的再造展现了其历史流变中的不变逻辑,即为特定时代的受教育者提供共同价值。德国古典大学赋予了liberal arts在古典意义上的完美形态,而新人文主义的自我塑造观念孕育了博雅教育的现代转向。科学革命终结了古典学术的内在统一性与道德理想,瓦解了古典liberal arts。美国现代大学则借助古典资源,经由三次改革浪潮重建了liberal arts。然而,古典教育凝聚文明精华的共同价值、塑造意义与学术整合力量,同现代科学的智识自由、价值分殊与学科分化特性相冲突,这是古今之变为现代大学再造liberal arts所深植的困境,liberal arts只能在钟摆的两端之间不断权衡。

The Use of Art Therapy in Alleviating Mental Health Symptoms in Refugees: A Literature Review

There are over thirty million refugees globally with severe experiences of trauma.Art therapy intervention allows for nonverbal expression and could alleviate mental health symptomatology among refugees.The present review’s aim was to integrate and summarize the previous research which examined the effects of visual arts on alleviating psychological conditions of refugees.However,due to the paucity of studies which solely used visual arts,we included studies that used visual arts alongside other modalities as part of an expressive arts therapy intervention.The present review synthesizes studies that examined the effect of art therapy on mental health issues of refugees from January 2000 to March 2021.Seven studies(child and adolescent sample,N=5 and adult sample,N=2)with a total of 298 refugee participants(n=298)met our inclusion criteria.The participants were from the Middle East and North Africa(MENA),Southeast Asia,and Europe.We found three commonly reported mental health disorders,namely Post Traumatic Stress Disorder(PTSD),anxiety,and Major Depression Disorder.The research highlights how art therapy interventions could be a great starting point to alleviate symptomatology among refu-gees.Four additional benefits of art therapy which were commonly reported across the seven studies emerged from this review:working with traumatic experience/loss,rebuilding social connection and trust,nonverbal com-munication and self-expression of loss and trauma,and retelling stories.Art therapy interventions could be used as a starting point in the healing process of traumatized refugees to encourage verbal articulation of their feelings and reduce mental health symptoms.Despite these promisingfindings,due to a dearth of robust methodologies,further research is required to assess the long-term effectiveness of art therapy.

Nanoparticle-mediated synergistic anticancer effect of ferroptosis and photodynamic therapy:Novel insights and perspectives

Current antitumor monotherapy has many limitations,highlighting the need for novel synergistic anticancer strategies.Ferroptosis is an iron-dependent form of nonapoptotic cell death that plays a pivotal regulatory role in tumorigenesis and treatment.Photodynamic therapy(PDT)causes irreversible chemical damage to target lesions and is widely used in antitumor therapy.However,PDT’s effectiveness is usually hindered by several obstacles,such as hypoxia,excess glutathione(GSH),and tumor resistance.Ferroptosis improves the anticancer efficacy of PDT by increasing oxygen and reactive oxygen species(ROS)or reducing GSH levels,and PDT also enhances ferroptosis induction due to the ROS effect in the tumor microenvironment(TME).Strategies based on nanoparticles(NPs)can subtly exploit the potential synergy of ferroptosis and PDT.This review explores recent advances and current challenges in the landscape of the underlyingmechanisms regulating ferroptosis and PDT,as well as nano delivery system-mediated synergistic anticancer activity.These include polymers,biomimetic materials,metal organic frameworks(MOFs),inorganics,and carrier-free NPs.Finally,we highlight future perspectives of this novel emerging paradigm in targeted cancer therapies.

Clinical Analysis of Transcatheter Arterial Chemoembolization Sequential Microwave Ablation Combined with Targeted Therapy and Immunotherapy in the Treatment of Large Hepatocellular Carcinoma

Objective: To investigate the safety and efficacy of Transcatheter Arterial Chemoembolization (TACE), sequential Microwave Ablation (MWA) combined with targeted therapy and immunotherapy versus TACE combined with targeted therapy and immunotherapy in the treatment of large hepatocellular carcinoma (defined as tumor diameter > 5 cm). Methods: The prospective cohort study was conducted, with 81 patients with large hepatocellular carcinoma who were admitted to Jingzhou Central Hospital from 2018 to 2022, they were divided into two groups, 41 patients received TACE sequential MWA combined with targeted therapy and immunotherapy (observation group), and 40 patients received single TACE combined with targeted therapy and immunotherapy (control group). The short-term efficacies after 3 months of treatment, the Disease Control Rate (DCR), the Overall Survival (OS), adverse drug reactions and complications were compared and analyzed between the two groups. Results: The Objective Response Rate (ORR) of the observation group was significantly higher than that of the control group (ORR: 85.4% vs 57.5%, P = 0.005), The median Progression-Free Survival (PFS) and median OS of the observation group were better than those of the control group (mPFS: 16 months vs 10 months, P = 0.004;mOS: 39 months. vs 24 months, P = 0.008). The 1-, 2- and 3-year progression-free survival rates of the observation group were 72.9%, 50.4%, and 25.6%, and those of the control group were 30.4%, 11.0%, and 3.7%. The 1-, 2- and 3-year overall survival rates of the observation group were 78.9%, 71.7%, and 65.2%, and those of the control group were 65.1%, versus 42.1% and 36.9%. There was no significant difference in the incidence of adverse drug reactions and complications between the two groups. In this study, the adverse drug reactions were mild in Grades 1 - 2. Conclusion: TACE sequential MWA combined with targeted therapy and immunotherapy has efficacy and safety.

Effects of Differential First-Line Antiretroviral Therapy(ART)Regimens on Mortality among HIV/AIDS Children in Southwest China:A 15-year Retrospective Cohort Study

Human immunodeficiency virus(HIV)is a serious public health concern.Globally,1.7 million(1.3–2.1 million)children aged 0–14 were living with HIV at the end of 2021,90%of whom lived in low-and middle-income countries.Acquired Immune Deficiency Syndrome(AIDS)remains the leading cause of mortality among children worldwide.

Low-temperature photothermal-induced alkyl radical release facilitates dihydroartemisinin-triggered“valve-off”starvation therapy

The high nutrient and energy demand of tumor cells compared to normal cells to sustain rapid proliferation offer a potentially auspicious avenue for implementing starvation therapy.However,conventional starvation therapy,such as glucose exhaustion and vascular thrombosis,can lead to systemic toxicity and exacerbate tumor hypoxia.Herein,we developed a new“valve-off”starvation tactic,which was accomplished by closing the valve of glucose transporter protein 1(GLUT1).Specifically,dihydroartemisinin(DHA),2,20-azobis[2-(2-imidazolin-2-yl)propane]dihydrochloride(AI),and Ink were co-encapsulated in a sodium alginate(ALG)hydrogel.Upon irradiation with the 1064 nm laser,AI rapidly disintegrated into alkyl radicals(R·),which exacerbated the DHA-induced mitochondrial damage through the generation of reactive oxygen species and further reduced the synthesis of adenosine triphosphate(ATP).Simultaneously,the production of R·facilitated DHA-induced starvation therapy by suppressing GLUT1,which in turn reduced glucose uptake.Systematic in vivo and in vitro results suggested that this radical-enhanced“valveoff”strategy for inducing tumor cell starvation was effective in reducing glucose uptake and ATP levels.This integrated strategy induces tumor starvation with efficient tumor suppression,creating a new avenue for controlled,precise,and concerted tumor therapy.

Bioorthogonal Engineered Virus‑Like Nanoparticles for Efficient Gene Therapy

Gene therapy offers potentially transformative strategies for major human diseases.However,one of the key challenges in gene therapy is developing an effective strategy that could deliver genes into the specific tissue.Here,we report a novel virus-like nanoparticle,the bioorthgonal engineered viruslike recombinant biosome(reBiosome),for efficient gene therapies of cancer and inflammatory diseases.The mutant virus-like biosome(mBiosome)is first prepared by site-specific codon mutation for displaying 4-azido-L-phenylalanine on vesicular stomatitis virus glycoprotein of eBiosome at a rational site,and the reBiosome is then prepared by clicking weak acid-responsive hydrophilic polymer onto the mBiosome via bioorthogonal chemistry.The results show that the reBiosome exhibits reduced virus-like immunogenicity,prolonged blood circulation time and enhanced gene delivery efficiency to weakly acidic foci(like tumor and arthritic tissue).Furthermore,reBiosome demonstrates robust therapeutic efficacy in breast cancer and arthritis by delivering gene editing and silencing systems,respectively.In conclusion,this study develops a universal,safe and efficient platform for gene therapies for cancer and inflammatory diseases.

Cell reprogramming therapy for Parkinson’s disease

Parkinson’s disease is typically characterized by the progressive loss of dopaminergic neurons in the substantia nigra pars compacta.Many studies have been performed based on the supplementation of lost dopaminergic neurons to treat Parkinson’s disease.The initial strategy for cell replacement therapy used human fetal ventral midbrain and human embryonic stem cells to treat Parkinson’s disease,which could substantially alleviate the symptoms of Parkinson’s disease in clinical practice.However,ethical issues and tumor formation were limitations of its clinical application.Induced pluripotent stem cells can be acquired without sacrificing human embryos,which eliminates the huge ethical barriers of human stem cell therapy.Another widely considered neuronal regeneration strategy is to directly reprogram fibroblasts and astrocytes into neurons,without the need for intermediate proliferation states,thus avoiding issues of immune rejection and tumor formation.Both induced pluripotent stem cells and direct reprogramming of lineage cells have shown promising results in the treatment of Parkinson’s disease.However,there are also ethical concerns and the risk of tumor formation that need to be addressed.This review highlights the current application status of cell reprogramming in the treatment of Parkinson’s disease,focusing on the use of induced pluripotent stem cells in cell replacement therapy,including preclinical animal models and progress in clinical research.The review also discusses the advancements in direct reprogramming of lineage cells in the treatment of Parkinson’s disease,as well as the controversy surrounding in vivo reprogramming.These findings suggest that cell reprogramming may hold great promise as a potential strategy for treating Parkinson’s disease.

A review of the literature on the use of CRISPR/Cas9 gene therapy to treat hepatocellular carcinoma

Noncoding RNAs instruct the Cas9 nuclease to site speifillyl cleave DNA in the CRISPR/Cas9 system.Despite the high incidence of hepatocellular carcinoma(HCC),the patient's outcome is poor.As a result of the emergence of therapeutic resistance in HCC patients,dlinicians have faced difficulties in treating such tumor.In addition,CRISPR/Cas9 screens were used to identify genes that improve the dlinical response of HCC patients.It is the objective of this article to summarize the current understanding of the use of the CRISPR/Cas9 system for the treatment of cancer,with a particular emphasis on HCC as part of the current state of knowledge.Thus,in order to locate recent developments in oncology research,we examined both the Scopus database and the PubMed database.The ability to selectively interfere with gene expression in combinatorial CRISPR/Cas9 screening can lead to the discovery of new effective HCC treatment regimens by combining clinically approved drugs.Drug resistance can be overcome with the help of the CRISPR/Cas9 system.HCC signature genes and resistance to treatment have been uncovered by genome-scale CRISPR activation screening although this method is not without limitations.It has been extensively examined whether CRISPR can be used as a tool for disease research and gene therapy.CRISPR and its applications to tumor research,particularly in HCC,are examined in this study through a review of the literature.

Cardiac Resynchronization Therapy in Heart Failure in Sub-Saharan Africa Environment: Experience of the Principal Hospital of Dakar (Senegal)

Background: Heart failure is a major public health challenge in sub-Saharan Africa. In patients with chronic Heart Failure and cardiac desynchrony, studies have suggested that cardiac resynchronization, can improve cardiac function and the quality of life of patients. However, in Sub-Saharan Africa, very few studies have been done on cardiac resynchronization which is in its infancy. The aim of this study is to report the local data from our hospital. Method: It was a transversal, descriptive and analytical study conducted from November 2019 to September 2022 at the Cardiology Department of the Principal Hospital of Dakar. Results: Twelve patients were implanted for Cardiac Resynchronization Therapy (CRT). The sex ratio was 8 males/4 females. The average age was 67 ± 11 years. Ten patients had non-ischemic heart disease and the two others had ischemic one. All of them had NYHA III or IV scores before CRT. The Quality of Life (QOL) was judged as poor by all of the patients. The average duration of QRS was 156 ± 9 ms. 27.9% ± 5% was the mean Left Ventricular ejection fraction (LVEF). Complications occur in 3/12 patients (25%). It was one CS vein dissection, one micro LV lead dislodgement and one phrenic nerve stimulation. Nine patients, who were considered as responders, had an improvement of QOL and NYHA, the LVEF increased and the end-diastolic dimension, and the duration of the QRS interval all decreased. Two patients do not respond and one (1) who had permanent atrial fibrillation, was a secondary responder after an atrioventricular junction ablation. Conclusion: Cardiac resynchronization is a therapy that improves the QOL of patients, the LVEF and reduces the duration of the QRS interval. However, this procedure is not without risk of complications. In sub-Saharan Africa, the major challenge is to improve the financial accessibility of this therapy for the population.

Tumor microenvironment-responsive artesunate loaded Z-scheme heterostructures for synergistic photo-chemodynamic therapy of hypoxic tumor

Tumor microenvironment(TME)with the particular features of severe hypoxia,insufficient endogenous H2O2,and overexpression of glutathione(GSH)markedly reduced the antitumor efficacy of monotherapy.Herein,a TME-responsive multifunctional nanoplatform(Bi2S3@Bi@PDA-HA/Art NRs)was presented for synergistic photothermal therapy(PTT),chemodynamic therapy(CDT),and photodynamic therapy(PDT)to achieve better therapeutic outcomes.The Z-scheme heterostructured bismuth sulfide@bismuth nanorods(Bi2S3@Bi NRs)guaranteed excellent photothermal performance of the nanoplatform.Moreover,its ability to produce O2 and reactive oxygen species(ROS)synchronously could relieve tumor hypoxia and improve PDT outcomes.The densely coated polydopamine/ammonium bicarbonate(PDA/ABC)and hyaluronic acid(HA)layers on the surface of the nanoplatform enhanced the cancer-targeting capacity and induced the acidic TME-triggered in situ“bomb-like”release of Art.The CDT treatment was achieved by activating the released Art through intracellular Fe2+ions in an H2O2-independent manner.Furthermore,decreasing the glutathione peroxidase 4(GPX4)levels by Art could also increase the PDT efficiency of Bi2S3@Bi NRs.Owing to the synergistic effect,this nanoplatform displayed improved antitumor efficacy with minimal toxicity both in vitro and in vivo.Our design sheds light on the application of phototherapy combined with the traditional Chinese medicine monomer-artesunate in treating the hypoxic tumor.

Revolutionizing gastric cancer treatment:The potential of immunotherapy

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.

获得性免疫缺陷综合征(acquired immunodeficiency syndrome,AIDS)的主要治疗方法为联合抗逆转录病毒治疗(combined antiretroviral therapy,cART),但部分患者由于免疫功能重建不全和不良反应,可能出现药物性肝损伤、消化功能下降、神经系统毒性和代谢紊乱等,严重影响了抗病毒疗效和患者生存质量,已成为AIDS治疗领域的瓶颈[1]。部分国家资助的中医药防治AIDS科研课题提出正虚(主要为肾虚)是AIDS发生发展的内在病理基础,以肾气与肾阴肾阳的功能下降为主要特征[2-3]。补肾制剂可能是缓解人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染患者病情和不良反应的可靠方式。金匮肾气丸是由地黄、山药、茯苓、牡丹皮、山茱萸、牛膝、泽泻等多味中药制成的综合制剂[4],具有温补肾阳、化气行水的作用。本研究首次采用金匮肾气丸与cART联用治疗HIV-1感染者,比较了金匮肾气丸与cART联用、单用cART对HIV-1感染者抗病毒疗效和不良反应的差异,试图为探索HIV-1感染者治疗的新途径提供参考。

Combinational therapy with Myc decoy oligodeoxynucleotides encapsulated in nanocarrier and X-irradiation on breast cancer cells

The Myc gene is the essential oncogene in triple-negative breast cancer(TNBC).This study investigates the synergistic effects of combining Myc decoy oligodeoxynucleotides-encapsulated niosomes-selenium hybrid nanocarriers with X-irradiation exposure on the MDA-MB-468 cell line.Decoy and scramble ODNs for Myc transcription factor were designed and synthesized based on promoter sequences of the Bcl2 gene.The nanocarriers were synthesized by loading Myc ODNs and selenium into chitosan(Chi-Se-DEC),which was then encapsulated in niosome-nanocarriers(NISM@Chi-Se-DEC).FT-IR,DLS,FESEM,and hemolysis tests were applied to confirm its characterization and physicochemical properties.Moreover,cellular uptake,cellular toxicity,apoptosis,cell cycle,and scratch repair assays were performed to evaluate its anticancer effects on cancer cells.All anticancer assessments were repeated under X-ray irradiation conditions(fractionated 2Gy).Physicochemical characteristics of niosomes containing SeNPs and ODNs showed that it is synthesized appropriately.It revealed that the anticancer effect of NISM@Chi-Se-DEC can be significantly improved in combination with X-ray irradiation treatment.It can be concluded that NISM@Chi-Se-DEC nanocarriers have the potential as a therapeutic agent for cancer treatment,particularly in combination with radiation therapy and in-vivo experiments are necessary to confirm the efficacy of this nano-drug.
