It is difficult to treat malignant tumors, neurodegenerative diseases, and vascular diseases. For pathogenesis complexity of these diseases, researchers have focused on finding more drugs with high efficacy and low side effects. As a potential first-in-class drug, RRx−001 is expected to be an important first-line drug in tumor immunology, radiosensitizer and radio protecter. Currently, RRx−001 entered phase Ⅲ clinical trials. The data of the phase Ⅱ clinical trials demonstrated its safety and effectivity as a single agent and in combination with first-line clinical drugs. The novel mechanisms of RRx−001 and the result of main clinical trials were summarized, which could be valuable to further optimization and clinical application.

Objective:To construct an early rehabilitation management model for postoperative kinesiophobia patients after total knee arthroplasty (TKA) based on a topic-oriented quality control circle method, aiming to improve the quality of early rehabilitation management.Methods:Using a convenience sampling method, 120 TKA patients with kinesiophobia treated in the Department of Orthopedics at the First Affiliated Hospital of Zhengzhou University from January to April 2022 and September to December 2022 were selected. The patients from January to April 2022 were set as the control group, and those from September to December 2022 were set as the observation group, with 60 patients in each group. The control group received routine rehabilitation management after TKA surgery, while the observation group received the early rehabilitation management model based on the 10 steps of the topic-oriented quality control circle (topic selection, activity planning, clarification of the topic, goal setting, countermeasure formulation, pursuit of optimal strategies, etc.) in addition to the routine management. The differences between the two groups were compared in terms of kinesiophobia score, knee function score, pain score, early rehabilitation assessment rate, effective analgesia rate, and 24-hour ambulation rate.Results:After the intervention, the observation group showed significantly lower knee pain scores (2.89±0.66) and kinesiophobia scores (23.27±4.87) compared to the control group, with a significantly higher knee function score (74.47±7.40), all differences were statistically significant (all P<0.01). Additionally, the observation group had a significantly higher early rehabilitation assessment rate, effective analgesia rate, 24-hour ambulation rate, early rehabilitation compliance rate, earlier time for the first ambulation, shorter hospital stay, and reduced costs compared to the control group, with all differences showing statistical significance (all P<0.01) . Conclusions:The application of the topic-oriented quality control circle to construct and implement an early rehabilitation management model for postoperative kinesiophobia patients after TKA can effectively improve the quality of early rehabilitation management, reduce kinesiophobia levels, enhance knee joint function, and alleviate the economic burden.

With the rapid advancements in pancreatic cancer diagnosis and treatment research,the Chinese Society of Clinical Oncology(CSCO)has released two editions of pancreatic cancer diagnosis and treatment guidelines in 2022 and 2024.The present article systematic-ally compares the differences between the two editions in terms of diagnostic stratification,treatment pathways,and supportive manage-ment.By integrating insights from cutting-edge international research,the scientific rationale and clinical value of the underlying guideline revisions are explored.Clinicians are encouraged to adopt the new guidelines to dynamically assess the biological characteristics and treat-ment tolerance of patients,thereby formulating personalized diagnosis and treatment plans that ultimately lead to the synergistic enhance-ment of both survival benefits and quality of life for patients.

Objective To systematically analyze the risk prediction instruments for central line associated bloodstream infection in ICU patients,with a view to provide references for clinical practice.Methods The PubMed,Embase,Web of Science,Cochrane Library,CIN AHL,CNKI,WanFang,VIP and CBM Database were searched from inception to May 2024.There were 2 researchers who independently screened the literature,extracted the information,and assessed the risk of bias and applicability of the included literature.Results 11 studies were involved in the final review,involving 9 risk prediction models and 2 risk assessment tables,9 of which validated the predictive efficacy or reliability and validity of the instruments.Conclusion The risk prediction instruments for central line associated bloodstream infection in ICU patients had good predictive efficacy and applicability,but the overall risk of bias was high.It is recommended that further examination,verification the existing instruments should be conducted,or to build a prediction instrument with low risk of bias and high applicability.

This study retrospectively analyzed 12 patients with transfusion-dependent, non-severe aplastic anemia (TD-NSAA) refractory to cyclosporine A (CsA) , who were treated with lusutrombopag monotherapy. These patients either had a variety of chronic comorbidities or medication-related risks, or they were unresponsive to or intolerant of other thrombopoietin receptor agonists (TPO-RA) . The median treatment duration with lusutrombopag was 4 months (range: 3-11 months) , while the median follow-up period was 8 months (range: 6-11 months) . The overall response (OR) rates at months 3, 6, and the end of follow-up were 50.0%, 58.3%, and 50.0%, respectively, with a median time to OR of 2 months (range: 1-4 months) . Complete response (CR) rates were 8.3%, 16.7%, and 16.7% at the same time points, with a median time to CR of 4 months (range: 2-5 months) . Adverse events were all Grade 1, with an incidence rate of 25.0%. During follow-up, one patient experienced a loss of OR after discontinuing treatment, with a relapse rate of 14.3%; no clonal evolution or mortality was observed. These findings suggest that lusutrombopag is both effective and well-tolerated in CsA-refractory TD-NSAA patients and represents a promising therapeutic option for those with poor treatment tolerability.

Existing studies have shown that Astragalus membranaceus(AM)and its active ingredients astragalus polysaccharides,oninon,and astragalus methyl glycosides can attenuate X-ray radiation-induced injury.However,there are no studies on how isoliquiritigenin(ISL)attenuate the bystander effect of bone marrow mesenchymal stem cells(BMSCs)induced by carbon ion radiation therapy for lung cancer.This study aimed to investigate the AM-derived small molecule ISL to enhance radiotherapy sensitivity by attenuating the carbon ion radiation-induced bystander effect(RIBE)in BMSCs to elucidate its mecha-nism of action.In this study,we established a C57BL/6 mouse lung cancer transplantation tumor model in vivo and a co-culture model of A549 cells and BMSCs in vitro,and the models were successfully treated with carbon ions.In further work,we used flow cytometry,immunofluorescence,Western blot,enzyme-linked immunosorbent assay(ELISA),inhibitor,short hairpin RNA(shRNA),Cell Counting Kit-8(CCK-8),and other methods to illustrate the mechanism.In the next experiments,we found that ISL combined with carbon ion radiotherapy had a significant anti-tumor effect and protected BMSCs from radiation damage.The aim of this study was to investigate the potential of ISL in enhancing the sensitivity of lung cancer cells to radiotherapy and attenuating RIBE in both in vitro and in vivo settings.Traditional Chinese medicine combined with radiation therapy is a promising and innovative treatment for non-small cell lung cancer.These results establish a theoretical foundation for further clinical development of ISL as a potential radiosensitizer option.
