Mapping the intellectual structure and landscape of colorectal cancer immunotherapy: A bibliometric analysis.

Immunotherapy, particularly immune checkpoint inhibitor (ICIs) therapy, stands as an innovative therapeutic approach currently garnering substantial attention in cancer treatment. It has become a focal point of numerous studies, showcasing significant potential in treating malignancies, including lung cancer and melanoma. The objective of this research is to analyze publications regarding immunotherapy for colorectal cancer (CRC), investigating their attributes and identifying the current areas of interest and cutting-edge advancements. We took into account the publications from 2002 to 2022 included in the Web of Science Core Collection. Bibliometric analysis and visualization were conducted using CiteSpace, VOSviewer, R-bibliometrix, and Microsoft Excel. The quantity of publications associated with this domain has been steadily rising over the years, encompassing 3753 articles and 1498 reviews originating from 573 countries and regions, involving 19,166 institutions, 1011 journals, and 32,301 authors. In this field, China, the United States, and Italy are the main countries that come forward for publishing. The journal with the greatest impact factor is CA-A Cancer Journal for Clinicians. Romain Cohen leads in the number of publications, while Le Dt stands out as the most influential author. The immune microenvironment and immune infiltration are emerging as key hotspots and future research directions in this domain. This research carries out an extensive bibliometric examination of immunotherapy for colorectal cancer, aiding researchers in understanding current focal points, investigating possible avenues for research, and recognizing forthcoming development trends.

CRIF1 enhances p53 activity via the chromatin remodeler SNF5 in the HCT116 colon cancer cell lines.

CR6-interacting factor 1 (CRIF1) is ubiquitously expressed in human tissues. CRIF1 was first identified as a Gadd45γ (also known as CR6)-interacting protein, and it was also identified in a human colon cancer cell line stably transformed with p53. These results suggested that CRIF1 functions in the nucleus with p53 and Gadd45 family proteins in the suppression of cell growth and tumor development. Here, we found that CRIF1 could be recruited to a specific region in the promoter of the p53 gene, eliciting an increase in the mRNA and protein levels of p53 as well as p53 functional target genes. These functions required CRIF1 to interact with SNF5. CRIF1 was further recruited to the upstream promoter region of the p53 gene to suppress cell cycle progression in HCT116 cells. To our knowledge, this is the first evidence indicating that SNF5 is indispensable for CRIF1-enhanced p53 activity and its function in the suppression of cell cycle arrest in human cancer cells.

[Changes of tongue and pulse parameters in 50 lung cancer patients treated with integrated traditional Chinese and Western medicine].

OBJECTIVE: To observe the changes of tongue and pulse parameters in lung cancer patients after combined treatment with integrated traditional Chinese and Western medicine, and to probe into the application of the tongue and pulse parameters in evaluation of integrated traditional Chinese and Western medicine therapy on lung cancer patients. METHODS: Electropulsograms and tongue pictures of 50 lung cancer patients were examined by TP-I digital electropulsography. The tongue and pulse parameters of the patients, including the indexes of moistness and dryness, thinness and thickness, fissure, swollenness and emaciation, greasiness and likeness of curd, and power spectral ratios (PSRs) 1, 2, 3, 4 and cepstrum spectral ratios (CSRs) 1, 2, 3, 4, were observed after 1-month and 2-month treatment with Yifei Kangliu Oral Liquid (a compound traditional Chinese herbal medicine) plus chemotherapy, respectively. The above parameters of the lung cancer patients were compared before and after the treatment. RESULTS: PSR1 increased, while PSR2 decreased significantly after 1-month and 2-month treatment as compared with before treatment (P < 0.05). PSR1 decreased, while PSR2 increased after 2-month treatment as compared with after 1-month treatment (P < 0.05). PSR4 after 1-month treatment was lower than before treatment (P < 0.05). The tongue parameters including the indexes of moistness and dryness, and greasiness and likeness of curd increased significantly after 1-month and 2-month treatment as compared with before treatment (P < 0.05). The index of thinness and thickness decreased, while the index of fissure increased significantly after 1-month treatment as compared with before treatment (P < 0.05). CONCLUSION: Tongue and pulse parameters can be regarded as one of reference indexes in evaluation of integrated traditional Chinese and Western medicine therapy on lung cancer patients.
