Targeted anti-tumor synergistic effects of Myc decoy oligodeoxynucleotides-loaded selenium nanostructure combined with chemoradiotherapy on LNCaP prostate cancer cells

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.

Effective combined therapy for pulmonary epithelioid hemangioendothelioma: A case report

BACKGROUND Pulmonary epithelioid hemangioendothelioma(P-EHE)is a rare disease.Thus far,consensus on a standard treatment for P-EHE has not been established given its low incidence worldwide.Apatinib combined with chemotherapy with doxorubicin/cyclophosphamide has been used as an effective combination treatment for human malignancies.However,the efficacy of this combination has not been reported in P-EHE cases.CASE SUMMARY We present the case of a 64-year-old woman with chest tightness,cough,and chest pain.Computed tomography showed multiple unresectable pulmonary nodules.She had been misdiagnosed with lung carcinoma and underwent gefitinib treatment at a hospital.Subsequently,the patient underwent a cardiothoracic surgery for further disease investigation.CD31,CD34,and Vimentin expression were detected in the resected nodule specimens by immunohistochemical analyses,and pathological analyses confirmed the diagnosis of P-EHE.Following this,four cycles of apatinib combined with chemotherapy with doxorubicin/cyclophosphamide were initiated.The patient demonstrated stabilization of multiple bilateral nodules and showed a dramatic improvement in the clinical presentation after combination treatment.The patient could not tolerate the side effects of chemotherapy.Therefore,she then continued apatinib monotherapy,which is ongoing to date.The patient was stable at the last follow-up after 24 mo.CONCLUSION Apatinib combined with chemotherapy with doxorubicin/cyclophosphamide may be an effective therapeutic option for P-EHE treatment.

Real world effectiveness of PCSK-9 inhibitors combined with statins versus statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease in China(RWE-PCSK study)

BACKGROUND The efficacy and safety of proprotein convertase subtilisin/kexin type 9(PCSK-9) inhibitors were confirmed by several clinical trials, but its effectiveness in routine clinical practice in China has not been evaluated. This study aims to describe the real world effectiveness of PCSK-9 inhibitors combined with statins compared with statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease(ASCVD).METHODS This is a multi-center observational study, enrolled patients from 32 hospitals who underwent percutaneous coronary intervention(PCI) from January to June in 2019. There are 453 patients treated with PCSK-9 inhibitors combined with statins in PCSK-9 inhibitor group and 2,610 patients treated with statins-based lipid lowering therapies in statins-based group. The lipid control rate and incidence of major adverse cardiovascular events(MACE) over six months were compared between two groups.A propensity score-matched(PSM) analysis was used to balance two groups on confounding factors. Survival analysis using Kaplan-Meier methods was applied for MACE.RESULTS In a total of 3,063 patients, 89.91% of patients had received moderate or high-intensity statins-based therapy before PCI, but only 9.47% of patients had low-density lipoprotein cholesterol(LDL-C) levels below 1.4 mmol/L at baseline. In the PSM selected patients, LDL-C level was reduced by 42.57% in PCSK-9 inhibitor group and 30.81%(P < 0.001) in statins-based group after six months. The proportion of LDL-C ≤ 1.0 mmol/L increased from 5.29% to 29.26% in PCSK-9 inhibitor group and 0.23% to 6.11% in statins-based group, and the proportion of LDL-C ≤ 1.4 mmol/L increased from 10.36% to 47.69% in PCSK-9 inhibitor group and 2.99% to 18.43% in statins-based group(P < 0.001 for both). There was no significant difference between PCSK-9 inhibitor and statins-based treatment in reducing the risk of MACE(hazard ratio = 2.52, 95% CI: 0.49-12.97, P = 0.250).CONCLUSIONS In the real world, PCSK-9 inhibitors combined with statins could significantly reduce LDL-C levels among patients with very high risk of ASCVD in China. The long-term clinical benefits for patients received PCSK-9 inhibitor to reduce the risk of MACE is still unclear and requires further study.

Update of latest data for combined therapy for esophageal cancer using radiotherapy and immunotherapy:A focus on efficacy,safety,and biomarkers

Esophageal cancer usually has a poor prognosis.Given the significant breakthrough with tumor immunotherapy,an increasing number of clinical studies have demonstrated that the combination of radiotherapy and immune checkpoint inhibitors(ICIs)may have a synergistic effect and good outcome in esophageal cancer.Clinical studies of immunoradiotherapy(iRT)for esophageal cancer have proliferated enormously from 2021 to the present.However,a summary of the efficacy and toxicity of combined therapy to guide esophageal cancer treatment in clinical practice is lacking.For this review,we integrate the latest data to analyze and assess the efficacy and safety of iRT for esophageal cancer.In addition,we discuss better predictive biomarkers,therapeutic options for specific populations,and other challenges to identify directions for future research design.

Evaluation of modified hemodilution combined therapy in the treatment of acute ischemic stroke in the elderly

BACKGROUND： Thrombolysis therapy is not suitable for the elderly patients with acute ischemic stroke who delayed to be diagnosed for more than 3 hours, but traditional medicine is also not very ideal.

One patient from control group died of severe pulmonary infection. The rest 88 patients entered the stage of result analysis. ① Change of coagulation index and platelet aggregation rate： prothrombin time （PT）, activated partial thromboplastin time （APTT） and thrombin time （TT） of patients after therapy were significantly longer than those before therapy in the treated group and those after therapy in control group [After therapy in treated group： （18.4±1.9）, （41.8±2.1）, （19.7±1.7） s, Before therapy in treated group： （13.4±1.3）, （35.8±1.3）, （12.5±0.9） s, After therapy in control group： （16.9±1.5）, （39.1±1.1）, （11.9±2.1） s, P〈 0.05]：Concentration of fibrinogen （Fbg） after therapy was significantly lower than that before therapy in the treated group and that after therapy in control group[After therapy in treated group： （3.4±0.4） g/L; Before therapy in treated group： （4.3±0.7） g/L; After therapy in control group：（4.0±0.6） g/L; P 〈 0.05]. Platelet aggregation rate decreased from （37.92 ±0.85）% before therapy to （26.42±1.01）% after therapy （P 〈 0.01）. ②Change of blood lipid level： Levels of total cholesterol （TC）, triacylglycerol（TG） and low density lipoprotein cholesterol （LDL-C） of patients after therapy were significantly lower than those before therapy in treated group and those after therapy in control group [After therapy in treated group： （5.2±0.9）, （1.9±0.9）, （2.08±1.1） mmol/L, before therapy in treated group： （5.9±1.2）, （2.8±0.9）, （3.94±0.5） mmol/L, After therapy in control group： （6.0±1.1）, （2.6±0.8）, （3.84±0.9） mmol/L, P 〈 0.05]. ③Change of hemorheology index： Hematocrit of patients of treated group was significantly lower after therapy than before therapy [Before therapy： （43.84±4.55）% ;After therapy： （40.48±4.02）%;P 〈 0.05]. Blood flow rate of middle cerebral artery of patients of treated group was significantly lower before therapy than after therapy [（90±1.2）, （97±2.1） cm/s,P〈 0.01]. ⑤NDS of patients in treated group was significantly lower than of control group 14 days after therapy. The total effective rate after therapy was significantly higher in the treated group than in the control group （93%,78%, P 〈 0.05）. ⑥There was no obvious adverse effect. CONCLUSION： Modified hemodilution combined therapy can improve hemorheology, decrease hematocrit, increase blood flow rate of middle cerebral artery, so as to improve the impaired clinical neurological function of elderly patients with acute cerebral thrombosis through anticoagulation and antiplatelet aggregative activity as well as regulating blood lipid.

Back to the drawing board:Overview of the next generation of combination therapy for inflammatory bowel disease

Inflammatory bowel disease(IBD)is entering a potentially new era of combined therapeutics.Triantafillidis et al provide an insightful review of the current state of combination therapy,with a focus on the use of a combined biologic and immunomodulator,as well as emerging data on the future potential of dual-biologic therapy(DBT).While current evidence for DBT is limited,encouraging safety profiles and ongoing trials suggest a brighter future for this approach.The importance of controlled trials should be stressed in establishing new treatment paradigms.Ongoing prospective randomized trials of DBT and perhaps future combinations of biologics and small molecule therapies will hopefully guide the next generation of IBD care.

Immunotherapy for esophageal cancer:Where are we now and where can we go

Immune checkpoint inhibitor therapy has dramatically improved patient prognosis,and thereby transformed the treatment in various cancer types including esophageal squamous cell carcinoma(ESCC)in the past decade.Monoclonal antibodies that selectively inhibit programmed cell death-1(PD-1)activity has now become standard of care in the treatment of ESCC in metastatic settings,and has a high expectation to provide clinical benefit during perioperative period.Further,anti-cytotoxic T-lymphocyte–associated protein 4(CTLA-4)monoclonal antibody has also been approved in the treatment of recurrent/metastatic ESCC in combination with anti-PD-1 antibody.Well understanding of the existing evidence of immune-based treatments for ESCC,as well as recent clinical trials on various combinations with chemotherapy for different clinical settings including neoadjuvant,adjuvant,and metastatic diseases,may provide future prospects of ESCC treatment for better patient outcomes.

PRaG 3.0 therapy for human epidermal growth factor receptor 2-positive metastatic pancreatic ductal adenocarcinoma:A case report

BACKGROUND Pancreatic ductal adenocarcinoma(PDAC)is a highly fatal disease with limited effective treatment especially after first-line chemotherapy.The human epidermal growth factor receptor 2(HER-2)immunohistochemistry(IHC)positive is associated with more aggressive clinical behavior and shorter overall survival in PDAC.CASE SUMMARY We present a case of multiple metastatic PDAC with IHC mismatch repair proficient but HER-2 IHC weakly positive at diagnosis that didn’t have tumor regression after first-line nab-paclitaxel plus gemcitabine and PD-1 inhibitor treatment.A novel combination therapy PRaG 3.0 of RC48(HER2-antibody-drug conjugate),radio-therapy,PD-1 inhibitor,granulocyte-macrophage colony-stimulating factor and interleukin-2 was then applied as second-line therapy and the patient had confirmed good partial response with progress-free-survival of 6.5 months and overall survival of 14.2 month.She had not developed any grade 2 or above treatment-related adverse events at any point.Percentage of peripheral CD8^(+) Temra and CD4^(+) Temra were increased during first two activation cycles of PRaG 3.0 treatment containing radiotherapy but deceased to the baseline during the maintenance cycles containing no radiotherapy.CONCLUSION PRaG 3.0 might be a novel strategy for HER2-positive metastatic PDAC patients who failed from previous first-line approach and even PD-1 immunotherapy but needs more data in prospective trials.

Tetrahedral DNA Nanostructure-modified Gold Nanorod-based Anticancer Nanomaterials for Combined Photothermal Therapy and Chemotherapy

Objective To develop an effective treatment strategy to simultaneously avoid fatal adverse effects in the treatment of oral cancer,combination therapy has been explored because of its multiple functions.This work aims to develop a novel type of gold-nanorod-based nanomaterials decorated with tetrahedral DNA nanostructures(TDN)carrying antitumor drugs,namely,GNR@TDN-DOX nanocomposites.Methods In the designed structure,TDN,with a three-dimensional geometry composed of DNA strands,can provide GC base pairs for binding with the anticancer drug doxorubicin(DOX).The photothermal heating properties,biocompatibility properties,and antitumor performance of obtained GNR@TDN-DOX nanocomposites were investigated to assess their application potential in tumor treatment.Results Systematic studies have shown that the obtained GNR@TDN-DOX nanocomposites have high photothermal conversion under the illumination of an 808-nm infrared laser,leading to effective antitumor applications.In addition,the cell viability study shows that GNR@TDN-DOX nanocomposites have good biocompatibility.In vitro studies based on A375 cells show that the GNR@TDN-DOX nanocomposites can effectively eliminate cancer cells because of the combination of photothermal therapy induced by GNRS and chemotherapy induced by TDN-carrying DOX.The result shows that the obtained GNR@TDN-DOX nanocomposites have efficient cellular uptake and lysosome escape ability,together with their nuclear uptake behavior,which results in a significant antitumor effect.Conclusion This work has demonstrated a potential nanoplatform for anticancer applications.

Forty-seven Cases of Gonitis Treated by A Combined Therapy of Chinese Drugs and Acupuncture

Osteoarthritis, a nonspecific inflammatory lesion, is a commonly seen joint disease. Clinically, it is mainly characterized by arthralgia, swelling, and motor impairment. Since the knee joint is the load-bearing joint of the human body, and is susceptible to trauma, gonitis tends to have the highest morbidity in the four limbs, which manifests itself arthritis of patella and femur at the early stage; narrowness or disappearance of the medial joint space at the mid stage; and damage of the cartilage accompanied with flexion deformity at the late stage. In recent years, based on the experience of Prof. Cao Yiming, the author has treated 47 cases of gonitis by combined use of Chinese drugs and acupuncture, and obtained satisfactory therapeutic results as reported in the following.

Methods： 162 cervical cancer patients after the whole palace resection pelvic lymphadenectomy were divided into three groups, and then accepted radiotherapy. The first group with 91 cases was accepted internal and external irradiation therapy before operation; the second group with 37 cases was given internal irradiation therapy before operation; the third group with 34 cases was given routine postoperative radiotherapy. External irradiation used ^60Co irradiation or a linear accelerator, to the whole basin, and the irradiation dose of ＂B＂ point in preoperative radiotherapy was 26-30 Gy, in postoperative radiotherapy was 46-50 Gy; intraluminal brachytherapy used ^192lr, the dose of ＂A＂ point was 5-15 Gy. Results： The 5-year survival rate of preoperative combined radiotherapy group was 78.0% （71/91）, preoperative intracavitary radiotherapy group 64.9% （24/37）, and postoperative radiotherapy group 35.3% （12/34）. Comparing the 5-year survival rates of the preoperative combined and postoperative irradiation groups, there was significant difference （P 〈 0.05）. The major complications were radioactive proctitis and cystitis, the complication incidences of three groups were 35.2% （32/91）, 32.4% （12/37）, 38.2% （13/34）, respectively, and the differences were not statistically significant （P 〉 0.05）. Conclusion： The intraluminal brachytherapy plus external irradiation can significantly increase the 5-year survival rate of patients with Ⅱa-Ⅲa stages, and the incidence of complications was not significant difference.

Photothermal and Chemotherapy Combined Therapy of B-CuS-DOX Based on/pH Dual Stimulation

Single chemotherapy is difficult to meet the needs of tumor cure. Photothermia combined with chemotherapy is anew and effective anti-tumor therapy. However, the drug loading of nanoparticles and increase in performance of photothermalconversion limits the therapeutic effect of combination therapy. In this study, two-dimensional boron (boron, B) nanoparticles wereprepared by ultrasonic exfoliation, and copper sulfide (CuS) nanoparticles and doxorubicin (DOX) were grown on the surface ofthe nanoparticles to form B-CuS-DOX nanoparticles. B-CuS carrier has high DOX drug loading capacity (864mg/g) and goodphotothermal conversion performance (photothermal conversion efficiency at 808nm is 55.8%). At the same time, it can achievedrug release and good photothermal response at near infrared and pH. The nanoparticles designed in this study are expected toprovide an effective chemotherapy-photothermal therapy strategy for tumor therapy in vivo.

Innovative combined therapy for multiple keloidal dermatofibromas of the chest wall: A novel case report

Dermatofibromas are benign soft tissue tumors that predominantly affect the limbs, and more rarely the chest.Keloidal dermatofibroma is a rare subtype with distinct clinicopathological features and an aggressive clinical course. By researching the evolution of the disease in this study, we aimed to summarize our experience of managing a rare patient who underwent five surgeries for keloidal dermatofibroma that developed sequentially in the upper arm and chest and propose a novel treatment for keloidal dermatofibroma. We concluded that keloidal dermatofibroma involving larger areas, high tension sites, and multiple localizations can be treated using the principles of pathological scar management.
