Introduction: Severe hypertriglyceridemia, though rare in pregnancy, is a clinically significant condition that poses substantial maternal and perinatal risks. Case: We present a case of a 42-year-old pregnant female with class I obesity and pre-existing type 2 diabetes mellitus, with a booking hemoglobin A1c 12.1%. Her poorly controlled diabetes was complicated by nephrotic syndrome, with a 24-hour urine protein 4.9 g/day. She also had bilateral diabetic retinopathies requiring multiple sessions of panretinal photocoagulation. Throughout the pregnancy, her triglycerides rose progressively, peaking at 30 mmol/L by 33 weeks. Investigations revealed normal thyroid function, urea 4.8 mmol/L, creatinine 66 umol/L, and albumin 26 g/dL. The patient was hospitalized at 33 weeks of gestation and started on an intravenous insulin infusion along with a very low-fat, low-carbohydrate diet prescribed by a dietitian. Pulmonary embolism was diagnosed during evaluation for maternal tachycardia, and subcutaneous enoxaparin was initiated. One week after admission in 35 weeks of gestation, the baby was delivered via emergency Caesarean section due to fetal distress. The baby was small for gestational age, with a birth weight of 1.9 kg, below the 10th percentile for gestational age, and required admission to the neonatal intensive care unit with oxygen support for pneumonia-related respiratory distress. Post-delivery, intravenous insulin infusion and dietary control were continued, reducing her triglyceride level to the lowest level of 8.3 mmol/L. Both mother and baby were discharged well. Lipid-lowering agents such as rosuvastatin and fenofibrate were started after breastfeeding stopped, aiming to normalize her triglyceride levels. Conclusion Hypertriglyceridemia in this patient was the result of uncontrolled diabetes mellitus with nephrotic-range proteinuria. Severe hypertriglyceridemia can cause acute pancreatitis and/or hyperviscosity syndrome, both of which are life-threatening to the mother and baby. Thus, rapid reduction of triglyceride levels is crucial. This case highlights the importance of achieving good diabetes control prior to pregnancy, with strict adherence to treatment and enhanced patient education.

Perceptual decision making refers to the process by which individuals make choices and judgments based on sensory information, serving as a fundamental ability for human adaptation to complex environments. While traditional research has focused on perceptual decision making in isolated contexts, growing evidence highlights the profound influence of social contexts prevalent in real-world scenarios. As a crucial factor supporting individual survival and development, social context not only provides rich information sources but also shapes perceptual decision making through top-down processing mechanisms, prompting researchers to recognize the inherently social nature of human decisions. Empirical studies have demonstrated that social information, such as others’ choices or group norms, can systematically bias individuals’ perceptual decisions, often manifesting as conformity behaviors. Social influence can also facilitate performance under certain conditions, particularly when individuals can accurately identify and adopt high-quality social information. The impact of social context on perceptual decisions is modulated by a variety of external and internal factors, including group characteristics(e.g., group size, response consistency), attributes of peers (e.g., familiarity, social status, distinctions between human and artificial agents), as well as individual differences such as confidence, personality traits, and developmental stage. The motivations driving social influence encompass three primary mechanisms: improving decision accuracy through informational influence, gaining social acceptance through normative influence, and maintaining positive self-concept. Recent computational approaches have employed diverse theoretical frameworks to provide valuable insights into the cognitive mechanisms underlying social influence in perceptual decision making. Reinforcement learning models demonstrate how social feedback shapes future choices through reward-based updating. Bayesian inference frameworks describe how individuals integrate personal beliefs with social information based on their respective reliabilities, dynamically updating beliefs to optimize decisions under uncertainty. Drift diffusion models offer powerful tools to decompose social influence into distinct cognitive components, allowing researchers to differentiate between changes in perceptual processing and shifts in decision criteria. Collectively, these models establish a comprehensive methodological foundation for disentangling the multiple pathways by which social context shapes perceptual decisions. Neuroimaging and electrophysiological studies provide converging evidence that social context influences perceptual decision making through multi-level neural mechanisms. At early perceptual processing stages, social influence modulates sensory evidence accumulation in parietal cortex and directly alters primary visual cortex activity, while guiding selective attention to stimulus features consistent with social norms through attentional alignment mechanisms. At higher cognitive levels, the reward system (ventral striatum, ventromedial prefrontal cortex) is activated during group-consistent decisions; emotion-processing networks (anterior cingulate cortex, insula, amygdala) regulate experiences of social acceptance and rejection; and mentalizing-related brain regions (dorsomedial prefrontal cortex, temporoparietal junction) support inference of others’ mental states and social information integration. These neural circuits work synergistically to achieve top-down multi-level modulation of perceptual decision making. Understanding the mechanisms by which social context shapes perceptual decision making has broad theoretical and practical implications. These insights inform the optimization of collective decision-making, the design of socially adaptive human-computer interaction systems, and interventions for cognitive disorders such as autism spectrum disorder and anorexia nervosa. Future studies should combine computational modeling and neuroimaging approaches to systematically investigate the multi-level and dynamic nature of social influences on perceptual decision making.

Objective To explore the protective effect and potential mechanism of propofol on acute kidney injury in septic rats.Methods A total of 84 adult SD rats were randomly divided into the sham surgery group,the model group and the treatment group.The sham surgery group only opened and closed the abdomen,while the model group underwent cecal ligation and perforation for modeling.In the treatment group,propofol(60 mg/kg)was intraperitoneally injected 30 minutes before modeling,and the same dose of propofol was intraperitoneally injected again 6 hours after modeling.The renal function and pathological changes of rats in each group were observed,24-hour survival status of rats in each group were recorded,and the 24-hour survival rate was calculated.A sepsis model was established in vitro by stimulating human renal tubular epithelial cell line with lipopolysaccharide(LPS),and the changes of apoptosis and oxidative stress of renal tubular epithelial cells were observed.The effects of propofol on oxidative stress and apoptosis of renal tubular epithelial cells stimulated by LPS were analyzed.Results The renal function of sepsis rats was decreased,the renal tissue structure was damaged,the 24-hour survival rate of rats was decreased significantly and the survival time was shortened.Propofol could effectively improve renal function,reduce renal Paller score,increase survival rate and prolong survival time in sepsis rats.LPS could induce apoptosis and oxidative stress of renal tubular epithelial cells,while propofol could inhibit oxidative stress and apoptosis of renal tubular epithelial cells.Conclusion Propofol can effectively alleviate acute kidney injury in septic rats,and its mechanism is related to the inhibition of apoptosis and oxidative stress of renal tubular epithelial cells.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.
