Objective To observe the value of digital subtraction angiography(DSA)iFlow parameters for predicting major amputation in patients with acute lower limb ischemia(ALLI)within 30 days after revascularization operation.Methods Totally 310 ALLI patients who underwent revascularization operation were retrospectively included and divided into major amputation group(n=36)and non-major amputation group(n=274)according to major amputation within 30 days after revascularization operation or not.iFlow parameters,including time to peak(TTP)and the Peak were obtained after processing of DSA images after revascularization.Receiver operating characteristic(ROC)curves were used to screen the optimal cut-off value of TTP and Peak for predicting major amputation post operation,and then TTP and Peak were dichotomized.The dichotomized TTP and Peak variables and other variables were admitted into a multivariate logistic regression to identify independent predictors of major amputation.Results TTP was higher and Peak was lower in major amputation group than those in non-major amputation group(both P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of TTP and Peak for predicting major amputation within 30 days post operation was 0.831 and 0.712,respectively,and the optimal cut-off value was 16 s and 1.53,respectively.Multivariate logistic regression analysis revealed that atrial fibrillation(AF)[OR(95％CI)=3.048(1.076,8.632)],livid skin appearance[OR(95％CI)=6.035(2.323,15.677)],TTP≥16 s after revascularization operation[OR(95％CI)=8.414(3.116,22.723)]and high myoglobin levels measured 48 h after operation[OR(95％CI)=1.001(1.001,1.001)]were all independent predictors of major amputation within 30 days in ALLI patients,but dichotomized Peak variable was not an independent predictor[OR(95％CI)=0.485(0.183,1.283),P=0.145].Conclusion TTP obtained through DSA iFlow was valuable for predicting major amputation in ALLI patients within 30 days after revascularization operation.

After being treated with acupuncture, some patients with idiopathic tinnitus may experience a short-term aggravation of tinnitus symptoms on the original basis. These symptoms can be gradually relieved and the overall condition fluctuates towards recovery. This phenomenon has brought some difficulties to patients and clinicians. Based on the academic view of TCM, "destroying pathogens and re-building balance", and in association with the existing understanding of acupuncture in modern medicine for tinnitus, this paper briefly discusses the mechanism and influencing factors of symptom fluctuation in patients with idiopathic tinnitus after acupuncture treatment in terms of both TCM and modern medicine, and proposes the future direction in the research of symptom fluctuation, so as to promote the recognition of clinicians and patients on symptom fluctuation and make rational use of its positive effects. Besides, it is hoped that more researchers will pay attention to symptom fluctuation and advance the exploration of it in academic field.

Objective The purpose of writing the"Expert consensus on the prevention and control of intracranial hypertension in adult critical illness"(here in after referred to as the"Consensus")aimed to standardize the nursing work related to the prevention and control of elevated intracranial pressure in adult critical illness,and prevent the occurrence of complications such as cerebral herniation.Methods Guided by evidence-based practice,domestic and foreign databases were searched for guidelines,expert consensuses,systematic evaluation,evidence summaries,and original research related to increased intracranial pressure.The search period is from database establishment to March 2024.The high-quality evidence and suggestions in the field was evaluated,extracted,and summarized to form a preliminary consensus.27 experts were invited to conduct 2 rounds of expert inquiry and 8 experts were invited to conduct 2 expert discussion meetings,to revise and improve the content of the initial draft,and to ultimately form a final consensus.Results The effective response rates for both rounds of inquiry questionnaires were 100％,with expert authority coefficients of 0.884,judgment coefficients of 0.964,and familiarity levels of 0.804.The Kendall harmony coefficients for 2 rounds of inquiry were 0.107 and 0.083(P＜0.01),respectively.The consensus includes 4 aspects,including identification,monitoring,prevention and control strategies,emergency treatment and care for increased intracranial pressure.Conclusion This"Consensus"has strong scientific validity and can provide reference basis for nurses to carry out prevention and control of intracranial pressure increase.

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.
