About 20% - 25% of women who visit gynecology department complain of vaginal discharge and leucorrhoea. An orally administered combination kit, containing 2 g secnidazole, 1 g azithromycin and 150 mg fluconazole (Azimyn FS Kit), has been successfully evaluated in clinical trials and used in several countries for management syndromic vaginal discharge due to infections. Methods: This is a longitudinal study which aimed to verify the clinical efficacy of the combined oral kit containing secnidazole, azithromycin and fluconazole (Azimyn FS Kit<sup><sup>®</sup></sup>) in the syndromic treatment of abnormal vaginal discharge in patients received in outpatient consultations in Kinshasa/DR Congo from March to September 2023. Results: Majority of patients had whitish vaginal discharge (51.6%) of average abundance (56.2%), accompanied by pruritus in 72.1% of cases, and dyspareunia in 23.5% of cases and hypogastralgia in 40.2% of cases. One week after treatment with the Azimyn FS<sup><sup>®</sup></sup> combined kit, at the greatest majority of patients (97.3%), abnormal vaginal discharge had decreased by more than 50% (84.1%). Two weeks after treatment with the Azimyn FS<sup><sup>®</sup></sup> combined kit, almost all patients (97.3%) no longer had abnormal vaginal discharge which had completely disappeared. Conclusion: A single dose of secnidazole, azithromycin and fluconazole in the form of an oral combi-kit (Azimyn FS Kit) has shown excellent therapeutic effectiveness in the syndromic treatment of abnormal vaginal discharge wherein patients were treated without diagnostic confirmation.展开更多

Methods: Eighty cases of AML patients treated with venetoclax combined with demethylating drugs in our hospital were selected from March 2021 to March 2024, including 40 cases of primary treatment patients and 40 cases of relapsed and refractory patients. The efficacy and safety of the combined drug therapy was analyzed. Results: The primary treatment group was presented with a complete remission (CR) rate of 40.5%, partial remission (PR) rate of 47.50%, no response (NR) rate of 12.50%, and a remission rate of 87.50%. The relapsed- refractory group was presented with a CR rate of 37.50%, PR rate of 42.50%, NR rate of 17.50%, and a remission rate of 87.50%. There was no statistical significance between the groups (P > 0.05). The hematological adverse reactions of the combined treatment for AML were leukopenia and the non-hematological adverse reactions were mainly infections, with an incidence rate of 87.50%. Conclusion: The efficacy of venetoclax combined with demethylating drugs in AML was remarkable and the treatment regimen can be adjusted according to the treatment-resistant response.展开更多

Selectivity can be achieved through treatment strategies that target tumor cells. A recent report from the Li laboratory （1） describes an elegant strategy to selectively kill tumor cells by combining several targeting strategies based on cell biological, physical, and molecular （genetic） properties of tumor and normal cells that enhances tumor cell killing in vitro and in an in vivo tumor xenograft model. The idea of using a multiplex targeting approach is reminiscent of strategies in which several antibiotics are used to treat bacterial infections while minimizing the chance that rare antibiotic-resistant mutants will arise within a population.展开更多

Its characteristics of being highly invasive and undergoing heterogeneous genetic mutation, as well as the presence of the blood–brain barrier(BBB), have reduced the efficacy of GBM treatment. The emergence of a novel therapeutic method, namely, sonodynamic therapy(SDT), provides a promising strategy for eradicating tumors via activated sonosensitizers coupled with low-intensity ultrasound. SDT can provide tumor killing effects for deep-seated tumors, such as brain tumors. However, conventional sonosensitizers cannot effectively reach the tumor region and kill additional tumor cells, especially brain tumor cells. Efforts should be made to develop a method to help therapeutic agents pass through the BBB and accumulate in brain tumors. With the development of novel multifunctional nanosensitizers and newly emerging combination strategies, the killing ability and selectivity of SDT have greatly improved and are accompanied with fewer side effects. In this review, we systematically summarize the findings of previous studies on SDT for GBM, with a focus on recent developments and promising directions for future research.展开更多

文摘In the present study,we investigated the synergistic effects of targeted methotrexate-selenium nanostructure containing Myc decoy oligodeoxynucleotides along with X-irradiation exposure as a combination therapy on LNCaP prostate cancer cells.Myc decoy ODNs were designed based on the promoter of Bcl-2 gene and analyzed by molecular docking and molecular dynamics assays.ODNs were loaded on the synthesized Se@BSA@Chi-MTX nanostructure.The physicochemical characteristics of nanostructures were determined by FTIR,DLS,UV-vis,TEM,EDX,in vitro release,and hemolysis tests.Subsequently,the cytotoxicity properties of them with and without X-irradiation were investigated by uptake,MTT,cell cycle,apoptosis,and scratch assays on the LNCaP cell line.The results of DLS and TEM showed negative charge(−9 mV)and nanometer size(40 nm)for Se@BSA@Chi-DEC-MTX NPs,respectively.The results of FTIR,UV-vis,and EDX showed the proper interaction of different parts and the correct synthesis of nanoparticles.The results of hemolysis showed the hemocompatibility of this nanoparticle in concentrations less than 6 mg/mL.The ODNs release from the nanostructures showed a pH-dependent manner,and the release rate was 15%higher in acidic pH.The targeted Se@BSA@Chi-labeled ODN-MTX NPs were efficiently taken up by LNCaP cells by targeting the prostate-specific membrane antigen(PSMA).The significant synergistic effects of nanostructure(containing MTX drug)treatment along with X-irradiation showed cell growth inhibition,apoptosis induction(~57%),cell cycle arrest(G2/M phase),and migration inhibition(up to 90%)compared to the control.The results suggested that the Se@BSA@Chi-DEC-MTX NPs can potentially suppress the cell growth of LNCaP cells.This nanostructure system can be a promising approach for targeted drug delivery and chemoradiotherapy in prostate cancer treatment.

文摘Despite decades of laboratory and clinical trials,breast cancer remains the main cause of cancer-related disease burden in women.Considering the metabolism destruction effect of metformin(Met)and cancer cell starvation induced by glucose oxidase(GOx),after their efficient delivery to tumor sites,GOx and Met may consume a large amount of glucose and produce sufficient hydrogen peroxide in situ.Herein,a pH-responsive epigallocatechin gallate(EGCG)-conjugated low-molecular-weight chitosan(LC-EGCG,LE)nanoparticle(Met–GOx/Fe@LE NPs)was constructed.The coordination between iron ions(Fe3+)and EGCG in this nanoplatform can enhance the efficacy of chemodynamic therapy via the Fenton reaction.Met–GOx/Fe@LE NPs allow GOx to retain its enzymatic activity while simultaneously improving its stability.Moreover,this pH-responsive nanoplatform presents controllable drug release behavior.An in vivo biodistribution study showed that the intracranial accumulation of GOx delivered by this nanoplatform was 3.6-fold higher than that of the free drug.The in vivo anticancer results indicated that this metabolism destruction/starvation/chemodynamic triple-combination therapy could induce increased apoptosis/death of tumor cells and reduce their proliferation.This triple-combination therapy approach is promising for efficient and targeted cancer treatment.

文摘Single-drug therapies or monotherapies are often inadequate,particularly in the case of life-threatening diseases like cancer.Consequently,combination therapies emerge as an attractive strategy.Cancer nanomedicines have many benefits in addressing the challenges faced by small molecule therapeutic drugs,such as low water solubility and bioavailability,high toxicity,etc.However,it remains a significant challenge in encapsulating two drugs in a nanoparticle.To address this issue,computational methodologies are employed to guide the rational design and synthesis of dual-drug-loaded polymer nanoparticles while achieving precise control over drug loading.Based on the sequential nanoprecipitation technology,five factors are identified that affect the formulation of drug candidates into dual-drug loaded nanoparticles,and then screened 176 formulations under different experimental conditions.Based on these experimental data,machine learning methods are applied to pin down the key factors.The implementation of this methodology holds the potential to signif-icantly mitigate the complexities associated with the synthesis of dual-drug loaded nanoparticles,and the co-assembly of these compounds into nanoparticulate systems demonstrates a promising avenue for combination therapy.This approach provides a new strategy for enabling the streamlined,high-throughput screening and synthesis of new nanoscale drug-loaded entities.
文摘This editorial discusses the article written by Chen et al that was published in the latest edition of the World Journal of Gastrointestinal Surgery.The current study found that programmed cell death 1 ligand 1(PD-L1)expression is considered as one of the pan-cancer biomarkers of immune checkpoint inhibitors(ICIs)treatment response.Four molecular subtypes are widely used to guide and evaluate the prognosis and diagnosis and treatment of gastric cancer(GC)patients.Clinical trials of ICI treatment including Nivolumab,Pembrolizumab,Avelumab have been conducted for metastatic GC(mGC).The effects of various single agent ICIs on mGC therapy varied.ICIs combined with chemotherapy can indeed bring survival benefits to patients with mGC.Combining ICIs with chemotherapy can give more patients the chance of surgery in the treatment of GC transformation.However,not all PD-L1 positive patients can benefit from it.It is urgent to find better biomarkers to predict the response of ICIs for more precise clinical treatment.
文摘Systemic therapy has become the standard treatment for patients with advanced hepatocellular carcinoma(HCC)whose treatment options are limited.However,the long-term patient response to drugs and the survival outcomes remain a concern.With increasing exploration of the HCC microenvironment,particularly in terms of T lymphocyte immunity,a new era of immunomolecular targeted therapy,based on molecular signaling,has arrived for advanced HCC.In the study of immune tolerance of the intrinsic HCC microenvironment,we found that multiple immunosuppressive mechanisms and immune checkpoint inhibitors,such as anti–programmed cell death protein 1/ligand of programmed cell death protein 1 therapy,have improved clinical outcomes in some patients with advanced HCC.Furthermore,various combination therapies have been investigated,and HCC types have been categorized into different types based on anti–programmed cell death protein 1(PD-1)/ligand of programmed cell death protein 1(PD-L1)treatment.In this paper,we first discuss the tumor-infiltrating T lymphocyte immunity and immune tolerance of HCC.We then clarify the basic mechanism of anti–PD-1/PD-L1 therapy and discuss the types of HCC based on anti–PD-1/PD-L1 therapy.Thereafter,we explain the relevant studies and mechanisms of combination therapy of anti–PD-1/PD-L1 with antiangiogenesis drugs or multikinase kinase inhibitors,anti–T lymphocyte–related signaling pathways in HCC,and other anti-CD8+T cell immune checkpoints.In this way,this review offers a deeper understanding of anti–PD-1/PD-L1 immunotherapy for advanced HCC,in order to provide better individualized treatments for patients with advanced HCC.
文摘Background: Vaginal discharge is one of most common and nagging problems that women face. About 20% - 25% of women who visit gynecology department complain of vaginal discharge and leucorrhoea. An orally administered combination kit, containing 2 g secnidazole, 1 g azithromycin and 150 mg fluconazole (Azimyn FS Kit), has been successfully evaluated in clinical trials and used in several countries for management syndromic vaginal discharge due to infections. Methods: This is a longitudinal study which aimed to verify the clinical efficacy of the combined oral kit containing secnidazole, azithromycin and fluconazole (Azimyn FS Kit<sup><sup>®</sup></sup>) in the syndromic treatment of abnormal vaginal discharge in patients received in outpatient consultations in Kinshasa/DR Congo from March to September 2023. Results: Majority of patients had whitish vaginal discharge (51.6%) of average abundance (56.2%), accompanied by pruritus in 72.1% of cases, and dyspareunia in 23.5% of cases and hypogastralgia in 40.2% of cases. One week after treatment with the Azimyn FS<sup><sup>®</sup></sup> combined kit, at the greatest majority of patients (97.3%), abnormal vaginal discharge had decreased by more than 50% (84.1%). Two weeks after treatment with the Azimyn FS<sup><sup>®</sup></sup> combined kit, almost all patients (97.3%) no longer had abnormal vaginal discharge which had completely disappeared. Conclusion: A single dose of secnidazole, azithromycin and fluconazole in the form of an oral combi-kit (Azimyn FS Kit) has shown excellent therapeutic effectiveness in the syndromic treatment of abnormal vaginal discharge wherein patients were treated without diagnostic confirmation.
文摘Objective: To investigate the therapeutic effect of applying venetoclax combined with demethylating drugs in treating patients with acute myeloid leukemia (AML). Methods: Eighty cases of AML patients treated with venetoclax combined with demethylating drugs in our hospital were selected from March 2021 to March 2024, including 40 cases of primary treatment patients and 40 cases of relapsed and refractory patients. The efficacy and safety of the combined drug therapy was analyzed. Results: The primary treatment group was presented with a complete remission (CR) rate of 40.5%, partial remission (PR) rate of 47.50%, no response (NR) rate of 12.50%, and a remission rate of 87.50%. The relapsed- refractory group was presented with a CR rate of 37.50%, PR rate of 42.50%, NR rate of 17.50%, and a remission rate of 87.50%. There was no statistical significance between the groups (P > 0.05). The hematological adverse reactions of the combined treatment for AML were leukopenia and the non-hematological adverse reactions were mainly infections, with an incidence rate of 87.50%. Conclusion: The efficacy of venetoclax combined with demethylating drugs in AML was remarkable and the treatment regimen can be adjusted according to the treatment-resistant response.

文摘Successful cancer therapy depends on selective killing of tumor cells while sparing normal cells. Selectivity can be achieved through treatment strategies that target tumor cells. A recent report from the Li laboratory （1） describes an elegant strategy to selectively kill tumor cells by combining several targeting strategies based on cell biological, physical, and molecular （genetic） properties of tumor and normal cells that enhances tumor cell killing in vitro and in an in vivo tumor xenograft model. The idea of using a multiplex targeting approach is reminiscent of strategies in which several antibiotics are used to treat bacterial infections while minimizing the chance that rare antibiotic-resistant mutants will arise within a population.
文摘Hepatocellular carcinoma(HCC)is one of the world’s deadliest and fastestgrowing tumors,with a poor prognosis.HCC develops in the context of chronic liver disease.Curative resection,surgery(liver transplantation),trans-arterial chemoembolization,radioembolization,radiofrequency ablation and chemotherapy are common treatment options for HCC,however,they will only assist a limited percentage of patients.Current treatments for advanced HCC are ineffective and aggravate the underlying liver condition.Despite promising preclinical and early-phase clinical trials for some drugs,existing systemic therapeutic methods for advanced tumor stages remain limited,underlining an unmet clinical need.In current years,cancer immunotherapy has made significant progress,opening up new treatment options for HCC.HCC,on the other hand,has a variety of causes and can affects the body’s immune system via a variety of mechanisms.With the speedy advancement of synthetic biology and genetic engineering,a range of innovative immunotherapies,such as immune checkpoint inhibitors[anti-programmed cell death-1(PD-1),anti-cytotoxic T lymphocyte antigen-4,and anti-PD ligand 1 cell death antibodies],therapeutic cancer vaccines,engineered cytokines,and adoptive cell therapy have all been used for the treatment of advanced HCC.In this review,we summarize the present clinical and preclinical landscape of immunotherapies in HCC,critically discuss recent clinical trial outcomes,and address future perspectives in the field of liver cancer.

文摘Background:Hepatocellular carcinoma(HCC)is the sixth most common cancer globally,with limited therapies and unsatisfactory prognosis once in the advanced stages.With promising advances in locoregional and systematic treatments,fast development of targeted drugs,the success of immunotherapy,as well as the emergence of the therapeutic alliance,conversion therapy has recently become more well developed and an effective therapeutic strategy.This article aimed to review recent developments in conversion therapy in liver transplantation(LT)for HCC.Data sources:We searched for relevant publications on Pub Med before September 2022,using the terms“HCC”,“liver transplantation”,“downstaging”,“bridging treatment”and“conversion therapy.”Results:Conversion therapy was frequently represented as a combination of multiple treatment modalities to downstage HCC and make patients eligible for LT.Although combining various local and systematic treatments in conversion therapy is still controversial,growing evidence has suggested that multimodal combined treatment strategies downstage HCC in a shorter time,which ultimately increases the opportunities for LT.Moreover,the recent breakthrough of immunotherapy and targeted therapy for HCC also benefit patients with advanced-stage tumors.Conclusions:In the era of targeted therapy and immunotherapy,applying the thinking of transplant oncology to benefit HCC patients receiving LT is a new topic that has shed light on advanced-stage patients.With the expansion of conversion therapy concepts,further investigation and research is required to realize the full potential of conversion treatment strategies,including accurately selecting candidates,determining the timing of surgery,improving the conversion rate,and guaranteeing the safety and long-term efficacy of treatment.

文摘Glioblastoma multiforme(GBM) is the most common primary malignant brain tumor, and it is associated with poor prognosis. Its characteristics of being highly invasive and undergoing heterogeneous genetic mutation, as well as the presence of the blood–brain barrier(BBB), have reduced the efficacy of GBM treatment. The emergence of a novel therapeutic method, namely, sonodynamic therapy(SDT), provides a promising strategy for eradicating tumors via activated sonosensitizers coupled with low-intensity ultrasound. SDT can provide tumor killing effects for deep-seated tumors, such as brain tumors. However, conventional sonosensitizers cannot effectively reach the tumor region and kill additional tumor cells, especially brain tumor cells. Efforts should be made to develop a method to help therapeutic agents pass through the BBB and accumulate in brain tumors. With the development of novel multifunctional nanosensitizers and newly emerging combination strategies, the killing ability and selectivity of SDT have greatly improved and are accompanied with fewer side effects. In this review, we systematically summarize the findings of previous studies on SDT for GBM, with a focus on recent developments and promising directions for future research.

文摘Ferroptosis has emerged as a potent form of no-apoptotic cell death that offers a promising alternative to avoid the chemoresistance of apoptotic pathways and serves as a vulnerability of cancer.Herein,we have constructed a biomimetic self-assembly nano-prodrug system that enables the co-delivery of gefitinib(Gefi),ferrocene(Fc)and dihydroartemisinin(DHA)for the combined therapy of both ferroptosis and apoptosis.In the tumor microenvironment,this nano-prodrug is able to disassemble and trigger drug release under high levels of GSH.Interestingly,the released DHA can downregulate GPX4 level for the enhancement of intracellular ferroptosis from Fc,further executing tumor cell death with concomitant chemotherapy by Gefi.More importantly,this nano-prodrug provides highly homologous targeting ability by coating related cell membranes and exhibits outstanding inhibition of tumor growth and metastasis,as well as no noticeable side-effects during treatments.This simple small molecular self-assembled nano-prodrug provides a new reasonably designed modality for ferroptosis-combined chemotherapy.
文摘Biologic agents have now been used in the management of inflammatory bowel disease(IBD)for many years where experience,expertise and confidence in their use has developed over time.In the United Kingdom,there are well established guidelines and recommendations for both single agent biologic treatments,and with combination therapy of a biologic agent with a small molecule agent in maintenance therapy.In recent times,there has been increasing interest and experience using dual biologic therapy(DBT)in IBD,primarily in difficult to treat and refractory cases with high disease burden.However,published data on use,experience and safety profiles is limited and large-scale studies remain low in number in this developing area.We therefore aim to present a summary and review of the available published data in this area to help us better understand the emerging role of DBT in IBD.
文摘Hepatocellular carcinoma(HCC)is presented frequently in late stages that are not amenable for curative treatment.Even for patients who can undergo resection for curative treatment of HCC,up to 50%recur.For patients who were not exposed to systemic therapy prior to recurrence,recurrence frequently cannot be subjected to curative therapy or local treatments.Such patients have several options of immunotherapy(IO).This includes programmed cell death protein 1(PD-1)and cytotoxic T-lymphocyte associated protein 4 treatment,combination of PD-1 and vascular endothelial growth factor inhibitor or single agent PD-1 therapy when all other options are deemed inappropriate.There are also investigational therapies in this area that explore either PD-1 and tyrosine kinase inhibitors or a novel agent in addition to PD-1 with vascular endothelial growth factor inhibitors.This minireview explored IO options for patients with recurrent HCC who were not exposed to systemic therapy at the initial diagnosis.We also discussed potential IO options for patients with recurrent HCC who were exposed to first-line therapy with curative intent at diagnosis.
