DNA methylation is an important epigenetic modification in mammals, playing a crucial role in various physiological processes, including cell differentiation and the gene expression regulation. The ten-eleven translocation (TET) protein family of DNA demethylases is integral to the regulation of DNA methylation, as it catalyzes the oxidation of 5-methylcytosine to form 5-hydroxymethylcytosine. During early embryonic development, the genome undergoes extensive DNA demethylation, and any aberration in this reprogramming process can result in abnormal embryonic development and physiological defects in offspring. The TET proteins, due to their unique dynamics and multifaceted roles, facilitate DNA demethylation and are involved in development and maturation of germ cells, the establishment of pluripotency, cell lineage differentiation, and transcriptional processes throughout mammalian embryogenesis. Furthermore, these proteins are closely associated with the maintenance of pregnancy and susceptibility of progeny to disease. Factors such as genetic mutations, maternal health conditions, and exposure to adverse environmental influences can impact TET protein activity, resulting in abnormal patterns of DNA demethylation. A comprehensive investigation of the related mechanisms of TET proteins is essential for enhancing our understanding of epigenetic regulation during early life, diagnosing and treating related diseases such as early fetal development retardation, and informing strategies for the prevention and management of pregnancy.This article reviews the regulatory role of DNA demethylation mediated by TET protein in mammalian embryonic development and pregnancy outcomes.

Objective:To explore the effect of the Nurse-Mini-CEX assessment method combined with PBL teaching mode in the cultivation of core competencies of undergraduate nursing students during ICU internships.Methods:A total of 64 nursing students interning in the ICU of a Third-grade Class-A hospital in Wuhu City from Sep 2022 to Aug 2023 were selected and randomly divided into 8 groups(8 students in each group).Using cluster sampling,4 groups(32 students)were assigned to the experimental group,receiving training via Nursing-Mini-CEX combined with PBL,while the remaining 4 groups(32 students)served as the control group,undergoing traditional clinical teaching.All students completed a 2-month pre-ICU clinical internship,followed by a 4-week ICU internship.Results:Compared to the control group,the experimental group showed significantly higher scores in five dimensions of nursing competency:nursing consultation,nursing physical examination,nursing diagnosis,nursing interventions,and holistic evaluation(P＜0.05).Additionally,the experimental group outperformed the control group in core competencies,including clinical nursing skills,leadership,interpersonal communication,professional development,critical thinking and research ability(P＜0.05).Self-efficacy in learning ability and behavior,as well as scores in personal accomplishment,depersonalization,and emotional exhaustion,were also higher in the experimental group(P＜0.05).Furthermore,the experimental group reported greater satisfaction with training content,teaching effectiveness,clinical skill development,teamwork cultivation,and overall satisfaction(P＜0.05).Conclusions:Nursing-Mini-CEX assessment combined with PBL teaching mode effectively enhances core competencies and self-efficacy,reduces burnout among ICU nursing interns,and achieve good clinical results,providing a theoretical and practical basis for the teaching and training of nursing students in ICU.However,as a single-center study,further validation and broader studies are warranted.

OBJECTIVE: To systematically search and integrate the best evidence for early rehabilitation of ICU-acquired swallowing dysfunction (ICU-ASD) using evidence-based medicine methods, providing high-quality evidence-based support for intensive care unit (ICU) healthcare professionals in implementing early rehabilitation assessment and intervention strategies for ICU-ASD. METHODS: The systematic search was conducted according to the "6S" pyramid evidence model. Multiple authoritative databases and resources were comprehensively searched, including: National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Canadian Medical Association Clinical Practice Guidelines Library (CMACPGL), New Zealand Guidelines Group (NZGG), Guidelines International Network (GIN), Registered Nurses' Association of Ontario (RNAO), Scottish Intercollegiate Guidelines Network (SIGN), PubMed/Medline, Cochrane Library, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, JBI Evidence-Based Health Care Database, Physiotherapy Evidence Database (PEDro), Chinese Medical Pulse Guidelines Website, SinoMed, CNKI, Wanfang Data, UpToDate, BMJ Best Practice, and professional association websites. The search encompassed guidelines, expert consensus statements, original studies [including cohort studies, quasi-experimental studies, and randomized controlled trials (RCT)], systematic reviews, and evidence summaries related to the prevention and management of ICU-ASD. The search period was limited from the inception of each database to November 30, 2024. The best evidence for early rehabilitation of ICU-ASD was summarized. The quality assessment of the literature and the extraction and synthesis of evidence were independently performed by two researchers with expertise in evidence-based medicine methodology. RESULTS: A total of 16 articles were included, consisting of 1 clinical decision-making study, 1 cohort study, 2 guidelines, 2 RCTs, 6 systematic reviews, 1 evidence summary, 2 expert consensuses, and 1 expert opinion. Following quality assessment, all 16 articles were incorporated into the analysis. For the early rehabilitation of ICU-ASD, five major themes were ultimately identified and 25 best evidence items were summarized, focusing on: multidisciplinary collaboration, swallowing screening and assessment, rehabilitation interventions, dietary and nutritional management, and oral hygiene. CONCLUSIONS The evidence summary provides individualized rehabilitation strategies for ICU-ASD patients, but their implementation still needs to be adapted to China's clinical practice context and patient preferences.

Objective:To investigate the establishment method, coordination points and safe transport management strategy of vena-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with downtime difficulties during cardiopulmonary bypass (CPB).Methods:A observation study was conducted. The patients admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to October 2022 were enrolled. These patients could not be separated from CPB and received VA-ECMO-assisted CPB surgery. The clinical data of the patients were recorded, including the basic information of the patients, the data of VA-ECMO establishment and transport process, the clinical indicators before and after VA-ECMO installation, the operation data of VA-ECMO and clinical outcomes. The experience was summarized from the aspects of extracorporeal membrane oxygenation (ECMO) establishment, transport process, team cooperation, and adverse events during transport. The clinical indicators before and after ECMO operation were compared. According to whether ECMO was successfully weaned, the patients were divided into a successful weaning group and a failure weaning group, and the clinical data between the two groups were compared.Results:Eighteen patients who underwent VA-ECMO-assisted CPB were enrolled, including 10 males and 8 females. The average age was (56.7±12.3) years old. Preoperative left ventricular ejection fraction (LVEF) was 0.46±0.10, and the main reasons for switching to VA-ECMO assistance included right ventricular systolic weakness in 6 cases, total cardiac systolic weakness in 5 cases, left ventricular systolic weakness in 4 cases, high pulmonary arterial pressure in 2 cases, and intractable ventricular fibrillation in 1 case. Among the 18 patients transferred from CPB to VA-ECMO, 10 cases were successfully weaned and 8 cases failed. In ICU, 8 cases survived, 5 cases died, and 5 cases gave up treatment and discharged. The average time for successful CPB to VA-ECMO establishment was (24.6±7.4) minutes, initial blood flow was (3.3±0.4) L/min, and transit time was (8.4±1.5) minutes. ECMO-assisted duration averaged (82.0±69.3) hours. Adverse events occurred in 9 patients during ECMO establishment and transfer. Post-ECMO onboarding for 4 hours, significant improvements were noted in blood lactic acid (Lac), pH value, mean arterial pressure (MAP), central venous oxygen saturation (ScvO 2) as compared with pre-ECMO onboarding [Lac (mmol/L): 10.5±7.0 vs. 15.2±6.8, pH value: 7.38±0.92 vs. 7.26±0.87, MAP (mmHg, 1 mmHg≈0.133 kPa): 74.9±13.7 vs. 58.4±17.0, ScvO 2: 0.678±0.065 vs. 0.611±0.061, all P < 0.01], and vasoactive-inotropic score (VIS) was also decreased (39.8±29.8 vs. 68.9±64.4, P < 0.01). Compared with successful weaning group, the patients in the failed weaning group exhibited higher pre-machine Lac (mmol/L: 18.8±7.8 vs. 12.3±4.3, P < 0.05), longer CPB time [minutes: 238.0 (208.8, 351.2) vs. 200.0 (185.8, 217.0), P < 0.05], and shorter ECMO-assisted time [hours: 19.5 (11.0, 58.8) vs. 94.5 (65.8, 179.8), P < 0.01]. However, there was no statistically significant difference in pre-machine pH value, ScvO 2, MAP, VIS score, and initial blood flow and establishment time of ECMO between the two groups. Conclusions:VA-ECMO is an effective circulatory aid for CPB surgery that cannot be weaned after CPB. The establishment and transfer of CPB "bridge" to ECMO aid depends on multi-disciplinary treatment (MDT) cooperation. The success rate of ECMO weaning is related to the Lac and CPB duration. If it is not possible to detach from the CPB successfully, VA-ECMO should be initiated as early as possible.

Objective:To integrate the best evidence for early rehabilitation of mechanically ventilated ICU-acquired weakness (ICU-AW) patients using evidence-based methods, providing evidence-based basis for standardized evaluation and intervention of early exercise therapy for mechanically ventilated ICU-AW patients.Methods:A systematic search was conducted on the American Thoracic Society (ATS) Clinical Practice Guidelines, Registered Nurses' Association of Ontario (RNAO), Guidelines International Network (GIN), Canadian Medical Association Clinical Practice Guideline Library (CMACPGL), BMJ Clinical Evidence, UpToDate, Scottish Intercollegiate Guidelines Network (SIGN), PubMed, Cochrane Library, National Guideline Clearinghouse (NGC), Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), UM-library, Physiotherapy Evidence Database (PEDro), National Institute for Health and Care Excellence (NICE), New Zealand Guidelines Group (NZGG), Chinese Medical Pulse Guidelines Website, CNKI and Wanfang data and other Chinese and English databases, professional team websites, and guideline websites for expert consensus, guidelines, randomized collected trial (RCT), systematic reviews and other evidence on early exercise rehabilitation for mechanically ventilated ICU-AW patients. The search time limit was from the establishment of the database to December 31, 2023. Literature search, screening, evaluation, information extraction was independently conducted by two evaluators with cross checking, and quality evaluation of the included literature was conducted.Results:A total of 21 literatures were enrolled, including 5 guidelines, 5 systematic reviews, 4 expert consensuses, and 7 RCT, all of which with high evidence level and all were enrolled. They were summarized into seven aspects with assessment screening, exercise safety standards, precautions, setting of exercise time, exercise intensity, exercise sequence, and recommended exercise content as the core, and 32 best evidences.Conclusions:The evidence summarized can provide evidence-based basis for standardized assessment and intervention of early exercise rehabilitation in mechanically ventilated ICU-AW patients. ICU medical practitioners need to combine the actual clinical environment, individual differences and rehabilitation goals of patients, to provide targeted health guidance and intervention for the prevention of ICU-AW in mechanically ventilated patients.

Objective To evaluate the bioequivalence of two formulations of minocycline hydrochloride capsules administered orally after fasting administration and fed administration.Methods An open-label,randomized,two-period,self-crossover design was employed to assess the bioequivalence study.Twenty-eight healthy subjects were enrolled in both fasting and fed groups,with each period involving a single administration of either the reference formulation or the test formulation of 50 mg,separated by a washout period of 7 days.The concentration of minocycline in human plasma was determined by HPLC-MS/MS and was used for calculating pharmacokinetic parameters and evaluating the bioequivalence of the test formulation and reference formulation.Results After oral administration of test and reference formulations of minocycline under fasting condition,the Cmax Values of minocycline were(541±137)ng·mL-1 for the test formulation and(558±140)ng·mL-1for the reference formulation.The AUC0-t values were(8 347±1 986)h·ng·mL-1 for the test and(8 205±1 790)h·ng·mL-1 for the reference.The t1/2 values were(18.2±2.84)h for the test and(18.0±3.05)h for the reference.After oral administration of the test and reference formulations of minocycline under fed condition,the Cmax values of minocycline were(349±72.1)ng·mL-1 for the test and(352±73.2)ng·mL-1for the reference.The AUC0-twere(6 428±1 077)h·ng·mL-1 for the test and(6 588±1 118)h·ng·mL-1 for the reference.The t1/2values were(18.5±3.10)h for the test and(18.4±3.21)h for the reference.Under fasting condition,the 90% confidence intervals for the geometric mean ratios of Cmax,AUC0-t,and AUC0-∞ between the test and reference formulations were(90.84%,101.46% ),(95.2%,102.8% ),and(95.31%,102.71% ),respectively.Under fed conditions,the 90% confidence intervals for the geometric mean ratios of Cmax,AUC0-t,and AUC0-∞ between the test formulation and the reference formulation were(94.71%,103.42% ),(95.40%,99.83% ),and(95.79%,100.02% ),respectively.Conclusions Bioequivalence of the two minocycline formulations was demonstrated after fasting administration and fed administration in a healthy Chinese population.
