This article provides a systematic interpretation and review of the Society of Critical Care Medicine 2024 Guidelines on Adult ICU Design. Developed based on the Grading of Recommendations Assessment, Development and Evaluation methodology, the guideline address five core themes: ICU layout, room design, infection control, infrastructure, and staff spaces, and put forward 17 evidence-based recommendations, including 5 good practice statements. This article briefly introduces the guideline development methods and evidence characteristics, and focuses on summarizing key recommendations, including high-visibility layouts, single-bed ward settings, natural lighting and noise reduction strategies, integrated infection prevention and control design, remote monitoring, and flexible capacity expansion capabilities. Furthermore, it delves into the applicability and localized implementation pathways within China's healthcare environment, analyzing limitations in terms of evidence quality, specialty applicability, and cost-effectiveness. Furthermore, by integrating the Chinese Guidelines for the Construction and Development of Critical Care Medicine (2025 Edition) and current domestic practices, the article proposes tiered and phased implementation recommendations. This article aims to provide domestic healthcare institutions with a scientific reference that balances international cutting-edge concepts with China's real-world conditions for the construction and renovation of ICUs, thereby promoting the development of intensive care environments centered on patient safety, healthcare worker well-being, and infection control.

Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.

Objective: To evaluates the association between maternal overweight/obesity during pregnancy and offspring risk of metabolic dysfunction associated steatotic liver disease (MASLD), providing theoretical evidence for early life MASLD prevention. Methods: An online search was conducted across ten databases (CNKI, Wanfang, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, PROSPERO, PQDT Global, ScienceDirect) for research literature on the association between maternal overweight/obesity during pregnancy and the development of MASLD in offspring, with the search period spanning from January 2014 to December 2024. Two researchers independently screened literature, extracted data, and assessed study quality. Statistical analysis was performed using R 4.3.3. Results: Ten studies involving 10 229 participants were included, comprising 4 cohort studies and 6 case control studies. Cohort studies showed that maternal overweight and obesity significantly increased offspring MASLD risk ( RR=1.59, 95%CI=1.06-2.39, P <0.05), with moderate heterogeneity ( I 2=56.9%, P =0.07). Case control studies indicated a positive association between maternal overweight/obesity during pregnancy and offspring risk of MASLD( OR=2.00, 95%CI=1.68-2.39, P < 0.05), with low heterogeneity ( I 2=48.8%, P =0.08). Conclusions Maternal overweight/obesity during pregnancy positively correlates with offspring MASLD risk. Gestational weight management may reduce the risk.

Objective To determine the effects of dexmedetomidine(Dex)in anesthesia on brain function,cerebral oxygen uptake rate(CERO2),difference in glucose content between cerebral ar-terial and venous blood(A-VDG)and jugular bulb oxygen saturation(SjvO2)and stress response in elderly patients with hypertensive cerebral hemorrhage.Methods A total of 96 elderly patients with hypertensive cerebral hemorrhage admitted to our hospital from January 2021 to June 2024 were recruited,and according to different anesthesia schemes,they were divided into the group A(propofol,remifentanil,sevoflurane combined with rocuronium anesthesia,48 cases)and group B(same anesthesia regimen as group A plus Dex).Glasgow coma(GCS)score and restlessness-sedation score 48 h after operation,postoperative recovery,stress indexes and cerebral glucose and oxygen metabolism before(T1)and at the end of operation(T2),and adverse reactions during the study were compared between the two groups.Results When compared with the group A,the group B had significantly higher GCS score 48 after surgery(13.95±0.28 vs 12.89±0.41,P＜0.01),and shorter awakening time,time to regain spontaneous breathing,extubation time and response time(P＜0.01).At T2,the levels of CERO2,A-VDG and SjvO2 were notably higher,while levels of cortisol,norepinephrine and epinephrine,and activity of renin were remarkably lower in the group B than the group A(P＜0.01).At T2,the both groups obtained increased levels of cortisol,norepinephrine,epinephrine and renin activity and SjvO2,while decreased CERO2 and A-VDG levels than the corresponding levels at T1(P＜0.05).The incidences of nausea and vomiting,cough,chills,restlessness and delirium was obviously lower in the group B than the group A(P＜0.05,P＜0.01).Conclusion For elderly patients with hypertensive cerebral hemorrhage,application of Dex in anesthesia can improve cerebral glucose and oxygen metabo-lism,reduce stress response,maintain the stability of perioperative vital signs,decrease the severi-ty of coma and incidences of delirium,nausea and vomiting,cough,chills,restlessness and other adverse reactions,and thus promote postoperative recovery.

This study explored the effect of the Mycobacterium tuberculosis(Mtb)PE/PPE family protein PE_PGRS37 on the growth of Mycobacterium smegmatis(Ms)and macrophage autophagy during Mtb infection.The pe_pgrs37 gene was amplified from Mtb genome through PCR,and the recombinant vector pAIN-PE_PGRS37 was successfully constructed through homologous recombi-nation.pAIN-PE_PGRS37 and pAIN were integrated into Ms through electroshock to construct pAIN-PGRS37/Ms and pAIN/Ms re-combinant bacteria.Western blotting indicated that the PE_PGRS37 protein was correctly expressed in pAIN-PE_PGRS37/Ms.The re-combinant bacteria were inoculated in 7H9/7H10 medium,and their colony morphology and growth curves were observed.No signifi-cant difference in colony morphology was observed between pAIN-PE_PGRS37/Ms and pAIN/Ms.The growth rate significantly in-creased between 10 and 16 h,and a plateau was reached at 26 h.After infection of U937 cells with pAIN-PE_PGRS37/Ms and pAIN/Ms,macrophage autophagy flow was detected with western blotting and immunofluorescence.In the pAIN-PE_PGRS37/Ms-infected group,compared with the pAIN/Ms-infected group,macrophage LC3-II and p62 protein expression was significantly up-regulated(P<0.001)and inhibited autophagosome and lysosome fusion.The intracellular survival of the recombinant bacteria was detected through colony counting,and pAIN-PE_PGRS37/Ms showed significantly greater survival in macrophages at 12 h,24 h,and 48 h than pAIN/Ms(P<0.05).Our results suggested that PE_PGRS37 protein promotes Mycobacterium survival in macrophages by blocking macro-phage autophagy flow,thus inhibiting macrophage autophagy.

Cardiovascular disease is the leading cause of death worldwide,with atherosclerosis(AS)-its core pathological manifestation-representing a multifactorial-driven chronic inflammatory disorder.The pathogenesis of AS involves intricate pathological mechanisms including dyslipidemia,inflammatory cascades,and plaque vulnerability,whose complexity necessitates animal models capable of accurately recapitulating specific pathological features.Genetically engineered murine models have emerged as pivotal tools for deciphering AS mechanisms,owing to their genetic manipulability,phenotypic traceability,and molecular conservation with human pathophysiology.This review provides a systematic overview of current methodologies for establishing AS mouse models,with particular emphasis on evaluating the pathological fidelity of dietary induction approaches,genetic modification strategies[notably apolipoprotein E(ApoE)-/-and low density lipoproteins receptor(LDLr)-/-models],and physical injury paradigms.

Background and Aims:To overcome the limitations of the transoral endoscopic thyroidectomy vestibular approach,such as restricted operative space and high complication risks,our team proposed a modified technique—endoscopic thyroidectomy via oral vestibule and submandibular approach(ETOSA).Preliminary studies have confirmed its safety and feasibility.This study aims to systematically evaluate the key factors affecting postoperative complications and operative time in ETOSA,explore the interactions among these variables,and construct a learning curve model to support its broader clinical adoption.Methods:A retrospective analysis was conducted on 125 patients with papillary thyroid carcinoma who underwent ETOSA at Xiangya Hospital,Central South University,between March 2022 and March 2023.Clinical characteristics,surgical parameters,and postoperative complications were extracted.A random forest model was employed to identify the major influencing factors for complications and operative time,as well as their interaction effects.Partial dependence plots based on case sequence were used to generate the learning curve.Results:All 125 patients successfully underwent ETOSA with no conversion to open surgery.The median operative time was 95.0 min,and the median intraoperative blood loss was 15.0 mL.The overall postoperative complication rate was 16.0%,with no cases of permanent hypoparathyroidism or hypocalcemia.The average neck appearance score was 1.05,indicating high patient satisfaction.The random forest analysis identified case number,surgical extent,lymph node yield(LNY),Hashimoto's thyroiditis(HT),and body mass index(BMI)as the key predictors of postoperative complications,while surgical extent,case number,LNY,HT,and blood loss were the key factors affecting operative time.A significant positive interaction was observed between case number and both surgical extent and HT,particularly in the first 20 cases,suggesting a higher risk during the early learning phase.The learning curve analysis indicated that surgical proficiency stabilized after 20 cases.Operative time and complication rate in the proficient phase were significantly lower than those in the learning phase(90.0 min vs.102.5 min;11.4%vs.40.0%,both P<0.05).Conclusion:ETOSA is a safe and feasible technique characterized by minimal invasiveness,favorable cosmetic outcomes,and a relatively short learning curve.case number,surgical extent,LNY,HT,BMI,and blood loss are key factors affecting complications and operation time.

Objective:To explore the latent profiles of self-perceived burden among young and middle-aged postoperative glioma patients and to compare the differences in quality of life among the identified profiles.Methods:From October 2022 to June 2023, a total of 184 young and middle-aged postoperative glioma patients were selected using convenience sampling from the Department of Neurosurgery at Beijing Tiantan Hospital, Capital Medical University. Data were collected using a general information questionnaire, the Self-Perceived Burden Scale (SPBS), and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Latent profile analysis was conducted using Mplus 8.3 software. Multinomial Logistic regression was used to analyze the influencing factors of different latent classes of self-perceived burden. The quality of life scores were compared across the different classes.Results:A total of 184 questionnaires were distributed, and 179 valid responses were collected, with an effective response rate of 97.3% (179/184). The self-perceived burden among young and middle-aged postoperative glioma patients was categorized into three latent profiles: low burden group (43.6%, 78/179), moderate burden group (36.3%, 65/179), and high burden group (20.1%, 36/179). Logistic regression analysis showed that age, gender, place of residence, and duration of illness were influencing factors for latent class membership ( P<0.05). The differences in quality of life total and subscale scores among the three latent classes were all statistically significant ( P<0.05) . Conclusions:Young and middle-aged postoperative glioma patients exhibit distinct latent profiles of self-perceived burden, and their quality of life varies significantly across these profiles. Medical staff should pay particular attention to patients who are younger, male, from rural areas, and with shorter disease durations, and provide personalized interventions to improve their quality of life.
