Objective: To establish an accurate and rapid typing method for Rh typing of samples from patients who have received recent blood transfusions by utilizing the difference in osmotic fragility between fresh and old red blood cells. Methods: A lysing solution suitable for destroying old RBCs was prepared. Sixty-one samples collected in our hospital in 2024 with Rh typing of double groups were treated with the lysing solution to remove the old allogeneic red blood cells while preserving the patient's own fresh red blood cells, followed by repeat Rh typing tests. Results: For 61 samples with Rh typing in double groups, 41 were accurately detected identified through the red blood cell lysis method, yielding an identification rate of 67.21%. No significant difference was observed compared to the detection rate of the commonly used capillary centrifugation modified method (χ
=0.103, P>0.05). Conclusion: The red blood cell lysis method provides a novel and rapid experimental approach for clinical use in processing Rh-typed samples that are of double groups, thereby offering a basis for Rh compatibility blood transfusion.

Objective To analyze the trends in disease burden and risk factors of depression among the elderly population in China from 1990 to 2021,and to provide a theoretical basis for the prevention,treatment,and policy-making of geriatric depression in China.Methods Data on the disease burden of geriatric depres-sion in China from 1990 to 2021,including the number of incident cases,disability-adjusted life years(DALYs),incidence rate,and DALY rate,were extracted from the 2021 Global Burden of Disease(GBD)database.The Joinpoint regression model was used to analyze the trends by calculating the annual percentage change(APC)and average annual percentage change(AAPC).The autoregressive integrated moving average(ARIMA)model was employed to predict the disease burden of geriatric depression over the next five years.Population attributable fractions(PAFs)were used to describe the risk factors for geriatric depression in China in 1990 and 2021.Results From 1990 to 2021,the number of incident cases and the incidence rate of geri-atric depression in China showed an overall upward trend.The most significant increase in incidence was ob-served in the 60-64 age group,while the prevalence rate increased notably in the ≥ 95 age group.The DALY rate showed the most pronounced upward trend in the 65-69 age group.The incidence,prevalence,and DALY rates of geriatric depression were higher in women than in men.Major risk factors included child-hood sexual abuse and intimate partner violence,with the impact of intimate partner violence being particular-ly significant among women.The ARIMA model predicted that the incidence,prevalence,and DALY rates of geriatric depression in China would decline over the next five years,with a greater decline observed in women than in men.Conclusions From 1990 to 2021,the incidence,prevalence,and DALY rates of geriatric de-pression in China showed an overall upward trend,with higher rates observed in women than in men.Greater attention should be paid to the elderly female population,with a focus on early prevention to reduce the dis-ease burden of geriatric depression.

Acute kidney injury (AKI) is one of the common critical illnesses characterized by a higher incidence, poor prognosis and limited effective therapeutics in clinical practice. Early diagnosis, etiologic differentiation and prognostic evaluation are crucial for improving outcomes and key components of integrated AKI management. However, the lack of ideal markers and intervention targets poses significant challenges in these aspects. Klotho, a protein predominantly synthesizes and secretes by renal tubular epithelial cells, has been shown to exert various protective effects on the kidney. Recent evidence suggests that abnormal Klotho levels are implicated in the pathogenesis and development of AKI, and hold promise for application in early diagnosis, etiologic recognition, and prognostic evaluation of AKI. Additionally, administration of exogenous Klotho protein or upregulation of endogenous Klotho expression has demonstrated preventive and therapeutic efficacy against AKI caused by a variety of etiologies. This paper reviewed the alterations in Klotho levels during AKI and evaluated its potential role in enhancing the integrated diagnosis and treatment of AKI.

Neurological diseases are characterized by high rates of disability, mortality, recurrence, and prolonged disease courses, making Neurological Intensive Care Unit patients vulnerable during the transition phase to risks such as downgraded monitoring and reduced treatment and nursing support. These factors contribute to higher rates of unplanned ICU readmission, decreased patient satisfaction, and reduced quality of life. Effective transitional care can reduce adverse events and improve clinical outcomes. This article introduces the relevant concepts of transitional care for Neurological Intensive Care Unit patients, summarizes domestic and international transitional care models, and explores the application outcomes of these models to provide guidance and support for transitional care practices in Neurological Intensive Care Unit patients.
