We aim to explore the differences of the psychological distress of postoperative chemotherapy patients with colorectal cancer between mindfulness intervention combined with homogeneous medical concepts and mindfulness intervention only. One hundred patients with colorectal cancer undergoing chemotherapy after surgery from Sep 2020 to Sep 2022 were enrolled and divided into active control group (Solution centered nursing interventions; homogenized medical and nursing professional teams; dedicated personnel responsible for “admission notices”; Regular follow-up after discharge) and mindfulness group (homogeneous medical concept + and concentrated solution + Mindfulness intervention) with 50 cases in each group according to different nursing methods. After nursing, the physical function, emotional function, cognitive function, and social function of the patients in the mindfulness group were significantly higher than those in the active control group. However, the overall life and economic difficulties of the patients in the mindfulness group were significantly lower than those in the active control group (P < 0.05). After nursing, the observation score, description score, action score, intrinsic experience score, non-judgment score and non-reaction score of the mindfulness group were significantly higher than those of the active control group (P < 0.05). The implementation of mindfulness intervention in colorectal cancer patients undergoing chemotherapy can alleviate the patients’ negative emotions, improve the level of mindfulness, and improve the quality of life of patients.

Background: This study sought to review colorectal cancer liver metastasis (CRLM) patients at multiple centers to analyze the factors affecting the success of conversion therapy in patients whose CRLM was initially evaluated as potentially resectable, to explore the effect of different treatment approaches on patient survival, and to provide a scientific reference for clinical treatment of CRLM. Methods: Fifty patients whose CRLM was initially evaluated as potentially resectable at 3 large Chinese general hospitals were enrolled in this retrospective study. Statistical analyses were carried out on the general data and pathological characteristic data to examine the clinical efficacy of the treatment approaches. The factors affecting the success of conversion therapy were analyzed by logistic regression. Additionally, follow-up appointments were conducted to examine survival, and survival curves were plotted using the Kaplan-Meier estimator. The effect of different clinical and pathological characteristics on CRLM patients was analyzed. Results: Seventeen patients achieved no evidence of disease (NED) status through surgical resection/ablation after undergoing conversion therapy. The multifactor analysis demonstrated that the number of liver metastases was the primary risk factor affecting the efficacy of conversion therapy (P<0.05). Survival analysis results showed statistically significant difference in overall survival (OS) between the NED group and the inconspicuous/progressive group (P<0.0001). Also, there was a statistically significant difference in the progression-free survival (PFS) between the NED group and the inconspicuous/progressive group (P<0.0001). Patients in the surgical resection group had better OS and PFS than those in the ablation group (P<0.0001 and P<0.01, respectively). The monofactor analysis demonstrated that the number and maximum diameter of liver metastases, serum Carcino-Embryonic Antigen (CEA) level, and BRAF V600E mutation status were factors affecting the OS of CRLM patients (P<0.05), of which BRAF V600E mutation was the primary determinant (P<0.05). Conclusions: Among the patients whose CRLM was initially evaluated as unresectable, those who underwent surgical resection of the primary lesions and liver metastases after receiving conversion therapy had the best prognosis. Thus, a thorough evaluation should be conducted to determine the effect of and survival factors affecting conversion therapy in the treatment of liver metastases.

Background: The incidence of colorectal cancer is high and on the rise. The genetic and protein expressions of RUNT-associated transcription factor 3 (RUNX3) and human epidermal growth factor receptor 2 (HER2) in colorectal cancer (CRC) and adjacent normal tissues were detected to preliminarily explore their correlation and clinical significance. Methods: CRC specimens excised during general surgery were selected for localization and quantitative analysis of protein and gene expression by SP (Streptavidin-peroxidase conjugated method) immunohistochemical staining, reverse transcription-polymerase chain reaction (RT-qPCR) and western blot. Combined with the patients’ data, the relationship between the expression of the two genes and tumor characteristics was analyzed. Log-rank test was used to analyze the correlation between the two proteins and survival prognosis of CRC patients. The expression of RUNX3 in RKO and HCT-116 was knocked down, and the relative expression of HER2 in the two cell lines was detected. Results: Immunohistochemical, RT-qPCR and Western blot results showed that the positive expression rate of RUNX3 in CRC was lower than in the normal group, and HER2 in CRC was higher than in the normal group. The positive expression of the two proteins correlated with the pT and pN stages of CRC. A significant negative correlation between the expression of the two genes in CRC. Follow-up results showed that the number of Runx3-positive patients was higher than negative ones, while HER2 positive were fewer than negative ones. In vitro experiments showed that RUNX3 protein and gene expression decreased, HER2 protein and gene expression increased in RUNX3 knockdown RKO and HCT-116 cells, respectively (P<0.05). Conclusions: The expression of RUNX3 and HER2 in CRC is related to the occurrence and development of CRC, and the two genes have a negative regulating effect.

Exploring the different molecular and clinicopathological features of nodal cancer based on single cell sequencing can reveal the intertumoral heterogeneity in cancer, and provide new ideas for early diagnosis, treatment and prognosis analysis of cancer. The hotspots, the features of worldwide scientific output, and the frontiers concerning single cell sequence related to cancer from 2011 to 2024 were determined using our bibliometric analysis. Web of Science Core Collection (WOSCC) database was searched for publications on single cell sequence associated with cancer that were published between 2011 and 2024. According to the journals, keywords, number of records, affiliations, citations, and countries, we conducted a bibliometric analysis. With the use of the data gathered from the WOSCC, geographic distribution was visualized, keyword, affiliation, and author cluster analyses were conducted, and co-cited references were reviewed and a descriptive analysis was also performed. From the analysis, it was concluded that 6189 articles that were published between 2011 and 2024 in total were identified. Frontiers in immunology is the leading journal with the most publications in field of the research. The five clusters that were identified for hotspots included immunotherapy, single-cell RNA sequencing, hepatocellular carcinoma, proliferation, gene expression appeared the most frequently. Journals, nations, organizations, scholars with most contribution and most referenced publications globally were extracted. Studies have mostly concentrated on the spatial transcriptomics, pan-cancer analysis, hepatocellular carcinoma et al. Single-cell sequencing plays a significant role in tumor diagnosis, treatment and prognosis.
