Onco-critical care has emerged as an important subspecialty at the intersection of critical care medicine and oncology, attracting increasing attention in recent years. With continuous innovations in cancer therapies, patient survival has improved significantly; however, the incidence of associated critical complications has also increased. The reasons for cancer patients requiring intensive care unit admission are diverse and can be broadly categorized into three groups: progression of the underlying malignancy, treatment-related complications, and coexisting classical critical illnesses. Traditional critical care concepts and practices face limitations in addressing the multidimensional and heterogeneous challenges of onco-critical care. Based on the core mechanism of critical illness development—host/organ unregulated response (HOUR)—this article systematically elaborates on how this framework advances understanding and clinical practice into onco-critical care, with emphasis on its manifestations in neuroendocrine, immune-inflammatory, and coagulation-metabolic pathways. The review summarizes recent advances in clinical assessment and phenotyping systems for onco-critical illness and discusses a multidisciplinary, integrated management strategy centered on the "Disease Control, Host Response Modulation, Organ Support" triad. Finally, major challenges and future directions in this field are outlined. By integrating existing evidence and theoretical insights, this review aims to provide new perspectives and a theoretical foundation for the clinical management of onco-critical illness, thereby promoting its evolution toward precision and standardization.

With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

ObjectiveTo explore the potential mechanism of Xiaoqinglong Decoction （小青龙汤， XD） in the treatment of allergic rhinitis. MethodsForty-five rats were randomly assigned to a control group， a model group， a loratadine group， low-， medium- and high-dose XD groups， and low-， medium- and high-dose Mahuang Decoction and Cang'erzi Powder （麻黄汤合苍耳子散， MDCP） groups. Except for the control group， rats were administered with ovalbumin （OVA） and aluminum hydroxide via intraperitoneal injection for 14 days to establish an allergic rhinitis model. After the 14th-day injection， nasal stimulation was continued with 20 μl of 10% OVA solution to maintain the model. Rats in the control group and the model group received 10 ml/（kg·d） of saline， whereas those in the loratadine group were administered with 0.9 mg/（kg·d） of loratadine. The low-， medium- and high-dose XD groups were administered XD at the dose of 2.7， 5.4， and 10.8 g/（kg·d）， respectively. The low-， medium- and high-dose MDCP groups were administered MDCP at the dose of 2.43， 4.86， and 9.72 g/（kg·d）， respectively. All treatments were administered by gavage once daily for 7 consecutive days. One hour after the final gavage， nasal symptom scores were recorded for all group of rats. The next day， serum levels of immunoglobulin E （IgE）， interleukin-4 （IL-4）， and interleukin-13 （IL-13） were measured. HE staining was used to observe the pathological morphology of the nasal mucosal tissue. Quantitative reverse transcription PCR （RT-qPCR） and Western Blot were performed to assess mRNA and protein expression of thymic stromal lymphopoietin （TSLP） and OX40 ligand （OX40L） in the nasal mucosa. ResultsCompared to the control group， total nasal symptom score in the model group significantly increased （P＜0.01）. HE staining revealed disrupted and adhered cilia， thickened basement membranes， and extensive inflammatory cell infiltration in the nasal mucosa. Serum levels of total IgE， IL-4， and IL-13， as well as TSLP and OX40L mRNA and protein expression in the nasal mucosa， were significantly elevated in the model group （P＜0.05 or P＜0.01）. Compared to the model group， the total nasal symptom scores in all drug intervention groups were significantly reduced； the serum total IgE levels in the loratadine group， the low- and medium-dose XD groups， and the low- and high-dose MDCP groups were significantly reduced； and the serum levels of IL-4 and IL-13 in the high-dose XD group and the high-dose MDCP group decreased （P＜0.05 or P＜0.01）. Nasal mucosal structure was improved. Except for the low-dose MDCP group， all other intervention groups showed a significant reduction in TSLP and OX40L mRNA expression in the nasal mucosa （P＜0.01）. All doses of XD and the medium- and high-dose MDCP groups significantly decreased the protein levels of TSLP and OX40L （P＜0.05）. The medium-dose XD group exhibited more improvement of nasal symptom scores and greater suppression of expression of TSLP and OX40L mRNA， and TSLP protein levels compared to the loratadine group （P＜0.05）. ConclusionXD may protect nasal mucosa of rats and alleviate allergic rhinitis by suppressing the TSLP/OX40L pathway， thereby attenuating Th2-mediated immune responses.

Despite significant advances in the field of critical care medicine over the past three decades, veno-arterial extracorporeal membrane oxygenation (V-A ECMO) remains the primary temporary mechanical circulatory support modality for patients with acute severe circulatory failure. With the accumulation of clinical experience and the increasing maturity of operational techniques in V-A ECMO, its technical management—particularly hemodynamic management—has become a key factor influencing patient outcomes. To further improve patient survival, the Chinese Critical Care Ultrasound Study Group, in collaboration with the Hemodynamic Therapy of Critical Care Collaborative Group and the Critical Care Medicine Branch of the China International Exchange and Promotive Association for Medical and Health Care, organized experts in critical care medicine to develop the Consensus on Hemodynamic Management in Adult Veno-Arterial Extracorporeal Membrane Oxygenation (2026 Edition). Based on years of clinical experience and the latest evidence-based medical evidence, this consensus formulates 15 systematic recommendations covering the entire process of V-A ECMO, including initiation, management during support, and weaning, aiming to promote standardized application of hemodynamic management in V-A ECMO.

Objective To evaluate the efficacy and safety of different surgical approaches for extracting high-positioned supernumerary teeth in the maxillary anterior midline region.Three surgical methods,the labial approach,the palatal approach,and a longitudinal incision beside the upper lip frenum were compared.Methods A total of 102 patients were recruited from the Department of Oral and Maxillofacial Surgery at the Affiliated Stomatological Hospital of Anhui Medical University between January and September 2024.They were randomly assigned via a random-digit table to three groups:the labial approach group(n=32),the palatal approach group(n=34),and the longitudinal incision beside the upper lip frenum group(n=36).Operation time,bone removal volume,post-operative midfacial swelling,degree of pain,and patient satisfaction across the three groups were recorded and compared.Results The average operation time in the labial approach group((20.50±3.02)min)and the longitudinal incision group((21.66±2.31)min)were both significantly shorter than that in the palatal approach group((29.19±3.40)min).In contrast,the palatal approach group demonstrated markedly lower postoperative swelling and pain scores(P＜0.05),along with the highest patient satisfaction,as reflected in the OHIP-14 scale.However,the palatal approach required the greatest bone removal volume,measuring(91.19±9.86)mm3.Conclusion Despite the palatal approach yielding superior outcomes in terms of postoperative pain control,swelling reduction,and patient satisfaction,it necessitated longer operation time and involved greater bone removal.Meanwhile,the labial approach and the longitudinal incision beside the upper lip frenum were comparable in all measured parameters,showing no statistically significant differences.Therefore,when extracting high midline impacted teeth in the maxillary anterior region,the choice of surgical approach should balance safety,minimal invasiveness,and patient satisfaction.

Objective:To explore the potential risk factors for cancer in patients with adenomatous polyps based on tumor markers and polyp lesion characteristics.Methods:A retrospective analysis was conducted to collect clinical data of 115 patients with adenomatous intestinal polyps who visited Nanjing Jiangbei Hospital from November 2022 to November 2024. They were divided into a cancerous group (17 cases) and a non cancerous group (98 cases) based on whether they were cancerous or not. Clinical data such as tissue type and polyp site and tumor marker levels such as carcinoembryonic antigen (CEA) and cancer antigen 72-4 (CA72-4) were collected at the first visit of all patients. The potential risk factors of adenomatous intestinal polyp canceration were investigated by Logistic regression analysis.Results:Univariate analysis revealed that the proportion of villous tubular adenomas, central depression of polyps, and lobulated polyps in the cancerous group were higher than those in the non cancerous group. Serum levels of CEA and CA72-4 were also higher in the cancerous group than in the non cancerous group : 13/17 vs.47.96% (47/98), 7/17 vs. 15.31% (15/98), 6/17 vs. 8.16% (8/98), (6.41 ± 1.81) μg/L vs. (4.23 ± 1.48) μg/L, (6.98 ± 1.83) kU/L vs. (5.66 ± 1.78) kU/L, respectively. The difference was statistically significant ( P<0.05). The results of Logistic regression analysis showed that the histological subtype of villous tubular adenoma, central depression of polyps, lobulated polyps, and high levels of CEA and CA72-4 were independent risk factors for cancer in patients with adenomatous intestinal polyps ( P<0.05). A nomogram risk model was constructed based on the influencing factors of canceration in patients with adenomatous intestinal polyps. The calibration curve was drawn, and the calibration curve was similar to the Y-X straight line, suggesting that the evaluation results of the nomogram risk model were highly consistent with the actual observation results. The receiver operating characteristic (ROC) curve was drawn. The results showed that the area under the curve (AUC) of the nomogram risk model for evaluating the canceration of patients with adenomatous intestinal polyps was 0.956, and the evaluation value was high. The decision curve was drawn, with the threshold of high risk as the horizontal coordinate and the net rate of return as the vertical coordinate. The results showed that when the threshold was in the range of 0 - 0.85, 0.96 - 0.99, the net benefit rate of predicting the cancer risk of patients with adenomatous intestinal polyps was greater than 0 and the maximum net benefit rate was 0.148. Conclusions:The histological classification of villous tubular adenoma, central depression of polyps, lobulated polyps, and high levels of CEA and CA72-4 are independent risk factors for cancer in patients with adenomatous intestinal polyps; The evaluation efficiency of the column chart risk model constructed based on the above factors is good.
