Precise management of the activity dose is a core component of the(early mobilization,EM)plan for ICU patients.However,the lack of clinical practice guidelines related to EM dose of existing programs hinders the implementation and development of EM in ICU patients to some extent.Therefore,this review focuses on 4 aspects,covering the definition of activity dose,assessment tools,the current clinical implementation status,and implications for future nursing.The aim is to systematically review the assessment tools and intervention strategies for the activity dose of EM in ICU patients,providing a reference for optimization of EM programs.

Objective To retrieve, evaluate, and summarize evidence on preventive management of high output and dehydration in ileostomy patients from both domestic and international sources. Methods Based on the "6S" evidence model, a top-down approach was employed to retrieve evidence on prevention and management of high output and dehydration in ileostomy patients. Databases searched included BMJ best practice, UpToDate, National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN), Registered Nurses' Association of Ontario (RNAO), Wound Ostomy and Continence Nurses Society (WOCNS), World Council of Enterostomal Therapists (WCET), Medlive Clinical Guidelines website, Joanna Briggs Institute (JBI), Cochrane Library, Embase, PubMed, Web of Science, CNKI, Wanfang Data, China Biology Medicine (CBM), and VIP Database. The search period was from January 2019 to April 2024. Results A total of 13 articles were included after retrieval and screening, comprising 2 guidelines, 2 expert consensuses, 4 systematic reviews, 4 evidence summaries, and 1 clinical decision aid. After translation, summarization, and organization of the included articles, 19 pieces of evidence across 11 categories were formulated, focusing on four items: definition and risk factors of high output in ileostomy, prevention and management strategies related to high output in ileostomy, prevention and management strategies related to dehydration in high-output ileostomy, and follow-up strategies for prevention of high output and dehydration after ileostomy surgery. Conclusion The evidence summarized based on the "6S" evidence model for prevention and management of high output and dehydration in ileostomy patients can provide a reference for clinical practice among healthcare professionals and medical decision-makers, thereby enhancing nursing quality and reducing patient rehospitalization rates.

Objective:To investigate the effect of water intake on bladder filling time before embryo transfer.Methods:A total of 189 patients were collected from February to June 2023 who were to undergo embryo transfer in Guangdong Women and Children Hospital. The patients were divided into group A ( n=61), group B ( n=64) and group C ( n=64) using a random number table and they were respectively given 300 mL, 500 mL and 700 mL water to drink. Abdominal ultrasound was performed every 15 min, a total of 1-5 times, from 45 min after drinking water until the bladder filling. The bladder filling time and bladder volume were collected. Kaplan-Meier method was used to compare the difference of bladder filling time among the three groups. The multivariate Cox regression was used to analyze factors of bladder filling time. Results:The cumulative bladder filling rates of group A, group B and group C at 105 min after drinking water were 57.4% (35/61), 90.6% (58/64) and 98.4% (63/64), respectively, and the median survival time (95% CI) of bladder filling was 105.0 (89.9-120.1) min, 60.0 (55.4-64.7) min and 60.0 (55.4-64.6) min, respectively. Pairwise comparison of Kaplan-Meier analysis revealed that the bladder filling time of group A was longer than that of group B and group C ( P<0.001), and there was no statistically significant difference between group B and group C ( P>0.05). The results of age-stratification analysis showed that the bladder filling time of younger patients in group A [90.0 (75.2-104.8) min] was longer than that in group B [60.0 (55.8-64.2) min, P<0.001] and group C [60.0 (55.1-64.8) min, P<0.001], and there was no statistical significance between group B and group C ( P>0.05); the bladder filling time of older patients in group C [60.0 (59.1-70.9) min] was shorter than that in group A [105.0 (89.9-120.1) min, P<0.001] and group B [75.0 (64.3-85.7) min, P=0.027], there was no statistical significance between group A and group B ( P>0.05). Multivariate Cox regression analysis showed that taking group A as reference, the hazard ratio ( HR, 95% CI) of groups B and C were 2.71 (1.78-4.21) and 3.23 (2.10-4.96), both P<0.001. The HR (95% CI) of the elderly patients was 0.69 (0.49-0.99), P=0.044. Conclusion:Water intake and age are independent factors affecting bladder filling time in embryo transfer patients. Patients are recommended to drink 500 mL of water 75 min before embryo transfer and appropriately increase the amount of water or extend the bladder preparation time after drinking water for elderly patients.

Objective To study the audiology characteristics of infants with human cytomegalovirus (HMCV) pneumonia.Methods Auditory brainstem response (ABR) and acoustic impedance test were carried on the following three groups respectively.The CMV(+) group had 115 infants who have been diagnosed with CMV pneumonia.CMV(-) group had 115 infants with pneumonia but did not have CMV infection.The control Group had 115 healthy children during the same period.A comprehensive evaluation of audiological characteristics and follow-up of hearing changes were studied.Results ①The CMV(+) group had 50 ears (21.74％),the CMV(-) group had 34 ears (14.78％),and the healthy group had 17 ears 7.39％ in ABR V wave threshold over 30 dB nHL.②The CMV(+) group had the highest rate of sens0rineural hearing loss(SNHL) compared with the CMV(-) and health control groups.③The percentages of the abnormal conductive hearing loss(CHL) in the CMV(+) group and CMV(-) group were higher than the health control group while there was no obvious difference between the CMV(+) and the CMV(-) groups.④During a 3-year follow-up,3 infants in the CMV(+)group who suffered SHL recovered while all the infants suffered CHL recovered in hearing.Conclusion Infants with CMV pneumonia have a higher rate of SHL,and pneumonia is likely to cause dysfunction of the middle ear,which might lead to CHL.We need to test infants with CMV pneumonia through thorough clinical audiology examinations and a long-term follow-up.

The pathogenesis of chronic hepatitis B (CHB) is mainly chronicity of hepatitis B virus infection caused by specific immune impairment. Modern studies have shown that activated specific inflammatory cells and the cytokines released by these cells such as interferon-γ (IFN-γ) and interleukin-4 (IL-4) play important roles in virus clearance and improvement of autoimmune function. With the constant development of traditional Chinese medicine, it has a widespread effect on the immune regulation system (especially IFN-γ and IL-4). This article reviews the research advances in immunologic mechanism if CHB in Chinese and Western medicine in recent years and provides new ideas and measures for traditional Chinese medicine to break the immune tolerance of CHB in terms of immune regulation.
