CRISPR/Cas9-based therapeutics face significant challenges in penetrating the dense microenvironment of solid tumors, resulting in insufficient gene editing and compromised treatment efficacy. Current nanostrategies, which mainly focus on the paracellular pathway attempted to improve gene editing performance, whereas their efficiency remains uneven in the heterogenous extracellular matrix. Here, the nanoCRISPR system is prepared with self-cascading mechanisms for gene editing-mediated robust apoptosis and transcellular penetration. NanoCRISPR unlocks its self-cascade capability within the matrix metallopeptidase 2-enriched tumor microenvironment, initiating the transcellular penetration. By facilitating cellular uptake, nanoCRISPR triggers robust apoptosis in edited malignancies, promoting further transcellular penetration and amplifying gene editing in neighboring tumor cells. Benefiting from self-cascade between robust apoptosis and transcellular penetration, nanoCRISPR demonstrates continuous gene transfection/tumor killing performance (transfection/apoptosis efficiency: 1st round: 85%/84.2%; 2nd round: 48%/27%) and homogeneous penetration. In xenograft tumor-bearing mice, nanoCRISPR treatment achieves remarkable anti-tumor efficacy (∼83%) and significant survival benefits with minimal toxicity. This strategy presents a promising paradigm emphasizing transcellular penetration to enhance the effectiveness of CRISPR-based antitumor therapeutics.

Objective:To investigate the supervisor-student relationship experience of nursing postgraduates from the perspective of humanistic care, identify the influencing factors for students' care experience, and provide a reference for building a good supervisor-student relationship pattern with humanistic care.Methods:Objective sampling was used to enroll 15 nursing postgraduates from colleges and universities in Wuhan, Hubei Province, Beijing, and Guangzhou, Guangdong Province. A semi-structured interview was then conducted in the students. Nvivo 12 software and the Colaizzi seven-step analysis method were used for sorting and analysis of the interview data.Results:Five themes and 15 sub-themes (namely, daily interpersonal interaction, academic interaction, emotional communication, internal growth, and professional literacy) were extracted. Among these themes, equal communication and mental health care were of particular concern to the students. The nursing postgraduates also expected their tutors to provide care in their daily life and help them develop three essential values.Conclusions:The supervisor-student relationship from the perspective of humanistic care is becoming more individualized and diversified. The tutors should provide multidimensional care to nursing postgraduates based on the students' personal characteristics. Meanwhile, they should focus on developing students' humanistic care abilities to cultivate high-level nursing professionals with a high humanistic care foundation.

Objective To explore the communication preferences for advance care planning(ACP)among elderly hospitalized patients and to provide references for improving the ACP implementation rate.Methods Convenience sampling was used to select elderly hospitalized patients from a tertiary hospital in Wenzhou City between April and November 2023.Face-to-face surveys were conducted using a general data collection form and a self-designed questionnaire on ACP communication preferences.Mixed Logit Model,willingness-to-pay analysis,relative importance analysis,and subgroup analysis were employed to explore preferences.Results 204 questionnaires were distributed and 200 valid questionnaires were recovered,with a valid questionnaire response rate of 98.04％.The Mixed Logit Model analysis indicated that key attributes-communication timing,communication form,family participation in ACP communication,legal validity of ACP documents,and out-of-pocket costs-significantly influenced preferences(P＜0.05).Willingness-to-pay analysis showed that changes in communication timing,communication form,and family participation altered patients' willingness to pay.Relative importance analysis ranked the top 3 attributes as commu-nication timing,communication form,and family participation.Subgroup analysis revealed that gender,education level,and residence location affected preferences(P＜0.05).Conclusion Key attributes of ACP communication affect elderly hospitalized patients' preferences and willingness to pay,with variations across subgroups.Healthcare professionals should develop optimal communication programs based on patient preferences and individual characteristics.

Next generation sequencing (NGS) technology is playing an increasingly important role in the diagnosis of genetic diseases. Whole exome sequencing (WES), which targets the coding regions of the genome, has been widely used in the diagnosis of genetic diseases for its low cost and high efficiency. However, compared to conventional methods, the Next Generation Sequencing (NGS) process is intricate, and there is variability in the expertise of data analysts and variant interpreters, which may lead to inconsistencies in the outcomes. To ensure the quality of testing and enhance the diagnostic rate of diseases, this consensus has provided recommendations regarding the laboratory setup, operational procedures, data analysis, result interpretation, and quality control for WES, with an aim to standardize its application in the detection of genetic disorders.

Objective:To present an evaluation indicator system for access to cancer screening services.Methods:The evaluation indicator pool was constructed through a scoping review. The theoretical framework was constructed based on the multi-source indicators, and the qualitative expert consultation method was employed to form the initial version of the three-level evaluation indicator system. Delphi expert consultation method was conducted in two rounds to evaluate the relevance, importance, and availability of the proposed evaluation indicator system. The expert positive coefficient, authority coefficient, coordination degree of expert opinions, and concentration of expert opinions were subjected to analysis. Subsequently, the three-level evaluation indicator system for access to cancer screening services was adjusted and determined based on the boundary value method and the open opinions of experts. Finally, the combination weight method was employed to determine the weight.Results:The initial version of the indicator system comprised 3 primary (first-level) indicators, 11 secondary (second-level) indicators, and 46 tertiary (third-level) indicators. Delphi expert consultation was conducted for the initial version, and 17 experts ultimately completed it, exhibiting a positive coefficient of 100% and an authority coefficient of 0.87. In comparison to the initial round of consultation, Kendall's W coefficient ranges (0.15-0.43, all P<0.05) of relevance, importance, and availability scores for each tertiary indicator in the second round exhibited an improvement. The analysis of the importance dimension indicates that expert opinions are also more concentrated, as evidenced by an increase of 8.5% and 7.0% in the proportion of the tertiary indicators with an arithmetic mean above 8 and a full mark ratio above 0.5, respectively. The final evaluation indicator system comprises three primary indicators, with the weights of structure evaluation, process evaluation, and outcome evaluation being 0.338, 0.378, and 0.285, respectively. It also comprises 11 secondary indicators and 45 tertiary indicators. Conclusions:The evaluation indicator system developed in this article can be an effective evaluation tool for quantitative comparison of access to cancer screening services across different populations, cancer types, and before and after intervention. Furthermore, it is recommended that the system undergo continuous optimization concerning its application.

Objective:To investigate the clinicopathological features, molecular pathology characteristics, and prognosis of non-small cell lung carcinoma (NSCLC) exhibiting co-expression of p40 and thyroid transcription factor1 (TTF1).Methods:Clinical and pathological data of six NSCLC cases with co-expression of p40 and TTF1 diagnosed at the First People′s Hospital of Xiaoshan District, Hangzhou, China from January 2016 to December 2023 were collected. Relevant literature was also reviewed.Results:NSCLC with co-expression of p40 and TTF1 commonly occurred in male smokers and had been in stage Ⅲ-Ⅳ when diagnosis. Microscopic examination revealed that the tumor cells were arranged in solid nests and sheets with marked atypia and visible mitotic figures. There was no prominent evidence of keratinization or glandular formation. The tumor cells diffusely co-expressed p40 and TTF1, exhibiting a dual immunophenotype characteristic of both squamous cell carcinoma and adenocarcinoma. Molecular testing of four NSCLC co-expressing p40 and TTF1 revealed the presence of common EGFR mutations, as well as mutations of NRAS (mutation rate of 2.09%), EML4-ALK (mutation rate of 24.77%), and PIK3CA (exon 10 c.1658 G>C p.S553T, mutation rate of 4.32%). All six tumors were poorly differentiated, highly invasive, and associated with poor prognosis. Four of the six patients experienced widespread metastasis and died within 7 to 30 months after the diagnosis or initial treatment.Conclusions:NSCLC with co-expression of p40 and TTF1 exhibits distinct clinicopathological features, immunophenotypes, molecular alterations, and clinical outcomes, characterized by rapid progression and poor prognosis. Pathologists should be vigilant in recognizing this entity to avoid misdiagnosis and missed diagnosis.
