Kirsten rat sarcoma viral oncogene homolog(KRAS)is a type of gene closely related to human tumors.And it's an important medical index to access the tumor development,prognosis and the efficacy of chemoradiotherapy.RAS mutations,in which KRAS mutations account for up to 85%,are the most common oncogenic driving mutations in human tumors.The most frequent KRAS mutation sites are codons 12,13,61 and 146.Codon G12,as the most frequently mutated one,can be divided into multiple subtypes,with G12D mutation being the most common,followed by G12V,G12C,etc.Colorectal cancer(CRC)is one of the tumors with the highest frequency of KRAS mutations.Both G12D and G12V are the most common mutation subtypes in CRC.In the field of treatments for CRC with KRAS mutations,targeted therapy had not been possible until the release of KRASG12C inhibitors in 2013,and new drugs have been developed one after another since then.This study summarized the mutations of KRAS and the advances in clinical research,including the latest advances in targeted drugs,chemotherapy drugs,immunotherapy drugs,ferroptosis,and other treatment methods.Among them,in terms of targeted drugs,this review explored KRASG12C inhibitors(sotorasib,adagrasib,D-1553,IBI351,etc.),anti-angiogenic drugs(monoclonal antibodies such as bevacizumab,remdesizumab,etc),small molecule multi-target tyrosine kinase inhibitors such as sunitinib,etc.In terms of immunotherapy drugs,there have also been many advances,such as the ARETHUSA clinical trial,which found that temozolomide reduced the tumor mutational burden(TMB)of O-6-methylguanine-DNA methyltransferase(MGMT)deficiency and RAS mutation in patients with advanced metastatic colorectal cancer(mCRC),providing innovative ideas for patient immunotherapy.For example,the combination of xindilimab with bevacizumab,oxaliplatin,and capecitabine can be used for first-line treatment of RAS mutations,microsatellite stability(MSS),and unresectable mCRC.Relevant studies have shown that the combination therapy has good therapeutic potential and controllable tolerability safety.This review explored the mechanisms of KRAS mutations and the latest advances in clinical research and treatment,in order to provide reference for the treatment of KRAS mutated colorectal cancer.

Although social cognitive impairment is commonly observed in patients with schizophrenia, how to effectively assess it and the clinical value of such evaluations warrant further discussion. In 2022, the release of the "European Psychiatric Association guidance on assessment of cognitive impairment in schizophrenia" provided guidance for research and clinical practices in this field. This article aims to analyze the necessity, effectiveness, and feasibility of conducting assessments in clinical settings based on the recommended approaches outlined in the guidance, considering the current clinical landscape in China.

Although cognitive impairment is considered a core symptom of schizophrenia and significantly impacts functional outcomes, it is often overlooked in clinical practice. The European Psychiatric Association released “Guideline on Assessment of Cognitive Impairment in Schizophrenia” in 2022, providing recommendations for research and clinical practice. This paper interprets the neurocognitive aspects of schizophrenia covered in the guidelines, introduces neurocognitive assessment tools used in China and their application settings, examines the relationship between subjective and objective assessments of cognitive impairment, and briefly discusses the connections between neurocognition and positive and negative symptoms. The paper also considers the future development of neurocognitive assessment tools in China.

Cognitive impairment in schizophrenia emerges early and persists, is a core symptom that severely affects social functioning. In 2022, the European Psychiatric Association published the " European Psychiatric Association guidance on assessment of cognitive impairment in schizophrenia", presenting the latest evidence and systematic review results. The guidance recommends comprehensive and detailed cognitive assessments for all individuals with schizophrenia, emphasizing the phase of early intervention. In conjunction with the recommendations of the guidance and the current state of research both domestically and internationally, this article provides an overview of cognitive impairment in schizophrenia, including definition, impact, selection of assessment tools, and limitations of cognitive assessments. It also connects with clinical practice in China, outlining the development and shortcomings of cognitive assessments for schizophrenia. It is suggested that a clinically simple questionnaire suitable for the Chinese population is needed to help physicians quickly identify cognitive impairment.

Cognitive impairment is one of the core features of schizophrenia and severely affects the prognosis of the disorder. Improving cognitive impairment is of great significance for alleviating symptoms, preventing relapses, enhancing the quality of life, and reducing the social burden in patients with schizophrenia. Based on the "Guidelines for the Assessment of Cognitive Impairment in Schizophrenia" published by the European Psychiatric Association in 2022, the article focuses on the intervention and management of cognitive impairment in schizophrenia patients following a systematic assessment, while also considering the specific context of practice in China. This paper reviews recent progress in cognitive impairment interventions for schizophrenia, providing clinical guidance across three key aspects: pharmacotherapy, physical therapy, and psychotherapy. Other interventions are also discussed. Additionally, it addresses the existing challenges and unresolved issues, aiming to provide a basis for decision-making in the current treatment of cognitive impairment in schizophrenia.
