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.

Objective To explore the genetic mutation characteristics, clinical manifestations, and treatment outcomes of catecholaminergic polymorphic ventricular tachycardia (CPVT), and to construct a quantitative scoring system for the severity of CPVT. The correlation between the mutations in different structural domains of the RyR2 gene and clinical manifestations and prognosis was analyzed. Methods By searching the PubMed and Web of Science databases for CPVT-related case reports published up to December 2024, data such as patient age, clinical manifestations, gene mutation sites, and treatment responses were collected. The quality of the literature was assessed using the CARE guidelines. The χ2 test was used to compare the severity and treatment response differences among different RyR2 structural domain mutation groups, and an innovative quantitative scoring system based on symptoms and efficacy was established. Results A total of 80 articles were included, with 102 patients in total. The quality of the literature was reliable. The age of the patients ranged from 1 to 84 years, with a higher proportion of children under 10 years old (25.5%). Female patients (54.9%) outnumbered males (45.1%). For CPVT patients, a quantitative scoring system was developed, with a total score of 2 to 10 points. Among them, 2 to 4 points were classified as mild, 5 to 7 points as moderate, and 8 to 10 points as severe. The results showed that severe patients often had a history of cardiac arrest and were resistant to treatment. Out of the 102 CPVT patients, RyR2 gene mutations accounted for 53.9% (55/102) of patients. Among them, the proportion of severe patients with N-terminal structural domain mutations was significantly higher than other regions, indicating that the RyR2 gene mutation structural domain has a significant impact on the severity of CPVT (χ2=17.530, P=0.008). The proportion of patients with mutations in the central hinge region who were ineffective with β-blockers reached 42.9% (3/7), which was significantly higher than other regions. Left cardiac sympathectomy was performed in 24 cases, and postoperative symptoms were almost completely controlled, significantly better than the drug treatment group.Conclusion Mutations in the N-terminal structural domain of the RyR2 gene are significantly correlated with the severity of CPVT. Left cardiac sympathectomy has gradually become an effective intervention for refractory cases. The scoring system proposed in this study can provide a basis for clinical stratified treatment. In the future, there is a need to expand the sample size to verify mutation-specific treatment strategies.

Anterior cruciate ligament (ACL) reconstruction yields favorable outcomes for restoring anteroposterior stability of the knee joint in patients with ACL tears. However, some patients still exhibit positive knee pivot shift after ACL reconstruction. Currently, combined ACL and anterolateral ligament(ALL) reconstruction has been accepted by most scholars. This surgical technique can restore the rotational stability of the knee joint in patients postoperatively and facilitate the early besumption of sports training after surgery. This article reviews the anatomical research, isometry-like point research, and reconstruction indications of the anterolateral ligament, as well as the surgical approaches, graft tunnel convergence, and reconstruction outcomes of combined anterior cruciate ligament and anterolateral ligament reconstruction.

Aging is characterized by a gradual deterioration of the physiological integrity of cells,tissues,and or-gans,resulting in a decrease in the body's physiological functions and an acceleration of the onset of age-related diseases,ultimately leading to death.The aging of the liver,which is a critical metabolic organ,is closely linked to various chronic liver diseases,such as hepatitis,liver fibrosis,and cirrhosis,and it ex-acerbates their prognosis and is a primary risk factor for their development at all stages.Therefore,a comprehensive understanding of the causes,mechanisms,and potential therapeutic targets associated with liver aging holds significant clinical importance for delaying or potentially reversing liver aging and for treating chronic liver diseases.Stem cells,which are potential anti-aging agents,present a promising and effective alternative for managing liver aging.In this review,we systematically assess the driving factors,characteristics,and underlying mechanisms of liver aging.We then discuss the current status of the use of stem cells to mitigate liver senescence and address related liver diseases.The review reveals that a stem cell-based approach represents a promising therapeutic strategy for combating liver aging and associated diseases.

Objective To investigate the characteristics and differences of congenital endowment in senile dementia population based on the theory of five circuits and six qi.Methods Based on the cross-sectional data of China Health and Retirement Longitudinal Survey(CHARLS)in 2018,the dementia status of the population aged 60 and above in China was evaluated by using the Mini-Mental State Examination(MMSE),and the five-circuit and six-qi features at birth in the senile dementia population were analyzed by descriptive statistics and Chi-square goodness-of-fit test.Results A total of 854 patients with senile dementia were included.The five-circuit and six-qi features at birth in the senile dementia population were as follows:most of them were born at the heavenly stem of Bing while the least at the heavenly stem of Ji and Geng(P＜0.001),most of them were born at the earthly branch of Wei while the least at the earthly branch of Zi(P＜0.001),most of them were born at the yearly circuit of excessive water circuit while the least at the yearly circuit of excessive gold circuit and deficient earth circuit(P＜0.001),and most of the patients were born at sitan of taiyin damp-earth and zaiquan of taiyang cold-water while the least at sitan of jueyin wind-wood and zaiquan of shaoyang ministerial fire;no statistically significant differences were found in the dominant qi and guest qi(P＞0.05);most of the patients were born in the year of combination of circuit and qi being Shunhua while the least in the year of combination of circuit and qi being same celestial correspondence(P＜0.001),and the patients born in the year of Shunhua usually were frequently distributed in heavenly-stem and earthly-branch year of Jiawu(P＜0.001).Conclusion There is a certain relationship between the congenital endowment at birth and the incidence of senile dementia in the population of senile dementia.The circuit-qi features at birth for the prevalence of senile dementia are the yearly circuit of excessive water circuit,sitan of taiyin damp-earth and zaiquan of taiyang cold-water,and the year of the combination of circuit and qi being Shunhua.The population born at the time with the above circuit-qi features are prone to suffer the injury of the kidneys,the heart,and the spleen,and then result into illness.

Objective Performing physical tasks in the low-pressure environment of space poses a significant physiological challenge for astronauts.This study investigates the localized thermophysiological effects of typical physical tasks on different body segments and analyzes the mechanisms by which low-pressure environments influence human task performance.The findings aim to provide a theoretical basis for the thermal control design of spacesuits,focusing on both localized thermoregulation and overall task performance.Methods Two typical physical tasks—15 kg weighted walking and 25 kg load-carrying—were conducted in a simulated low-pressure composite environment chamber.The chamber was set to an altitude-equivalent pressure of 57 kPa(4500 m),with a temperature of 26℃and humidity of 40％.Six non-acclimatized adult male participants were recruited.After environmental stabilization,12-point skin temperatures were recorded throughout the tasks,and localized temperature data were statistically analyzed.Results Under low-pressure conditions,different body regions exhibited distinct thermal responses over time depending on the task type,while the same body region showed varied responses under different task conditions.During walking,temperatures in the primary active regions(thighs and calves)decreased,with most other body regions(except the pelvis and feet)gradually cooling as the task progressed.In contrast,during load-carrying,temperatures in the primary active regions(back and upper arm muscles)increased significantly.Conclusion Astronauts performing different tasks in low-pressure environments experience distinct localized thermophysiological effects.Therefore,spacesuit thermal control systems should not only account for task intensity and metabolic differences but also adapt localized heating/cooling based on task-specific thermal profiles.This approach enables targeted intelligent thermal regulation,enhancing operational support in specific mission scenarios.

Heat stroke is a heat-related illness caused by an imbalance between the body's heat production and heat dissipation,which could lead to multiple organ dysfunction syndrome with a high mortality rate.Rapid and effective reduction of core body temperature is key to successful treatment.This article reviews recent progress in the treatment of heat stroke,including new understandings of organ injury mechanisms,the timing,velocity and goals of cooling treatment,evaluation and selection of traditional cooling techniques(such as cold water immersion),and scientific evaluation of new cooling technologies(such as blood purification technology and intravascular heat exchange cooling technology),aiming to promote understanding and treatment of heat stroke.

Objective To investigate the characteristics of thickness changes in peripapillary retinal nerve fiber layer(pRNFL)and identify related risk factors in patients with Moyamoya disease(MMD).Methods A retrospective study was conducted on 150 MMD patients(150 eyes)aged 6-65 years admitted to the Neurosurgery Department of the Fifth Medical Center,Chinese PLA General Hospital from May 2016 to December 2023(observation group),and 150 age-matched healthy volunteers(150 eyes)from the hospital's ophthalmology outpatient department(control group).Both groups were subdivided into pediatric(≤18 years),young adult(18-40 years),and middle-aged(40-65 years)subgroups.The pRNFL thickness in four quadrants was measured by optical coherence tomography(OCT):superior(pRNFL-Sup),inferior(pRNFL-Inf),nasal(pRNFL-Nas),temporal(pRNFL-Tmp),and average thickness(pRNFL-Avg).General clinical data and pRNFL thickness were compared between two groups.Univariate and multivariate logistic regression analyses were performed to identify risk factors for pRNFL thinning in MMD patients.The cohort was randomly divided into training(n=210)and validation(n=90)sets at a 7:3 ratio.A predictive model for pRNFL thinning in MMD patients was constructed based on logistic regression results.Model performance was evaluated using the area under the receiver operating characteristic curve(AUC),and clinical utility was assessed via decision curve analysis.Results Compared with control group,MMD patients exhibited significantly reduced pRNFL-Avg,pRNFL-Sup,pRNFL-Tmp,and pRNFL-Inf thickness(P<0.05 or P<0.001),while pRNFL-Nas showed no significant difference(P>0.05).In the pediatric subgroup,pRNFL-Avg and pRNFL-Inf were thinner(P<0.05).In the young adult subgroup,pRNFL-Avg and pRNFL-Sup were reduced(P<0.001 or P<0.05).In the middle-aged subgroup,pRNFL-Avg,pRNFL-Sup,pRNFL-Inf,and pRNFL-Tmp were all thinner(P<0.05 or P<0.001).Multivariate logistic regression identified visual field defects(OR=15.28,95%CI 2.95-79.10),disease duration(OR=1.11,95%CI 1.05-1.18),and the number of involved cerebral vessels(OR=1.49,95%CI 1.01-2.22)as independent risk factors for pRNFL thinning.The predictive model achieved AUC of 0.94(95%CI 0.91-0.97)and 0.95(95%CI 0.91-0.99)in the training and validation sets,respectively.Decision curve analysis confirmed the model's favorable clinical net benefit.Conclusion Thinning of pRNFL was observed in Moyamoya disease patients with visual field defects,disease duration,and cerebral vascular involvement identified as independent risk factors for pRNFL atrophy.

Objective To discuss the clinical value of flat head CT of two-way digital flat angiography system(DSA)in predicting symptomatic intracranial hemorrhage in patients with acute anterior circulation-large vessel occlusion cerebral infarction occurring within 24 hours after operation.Methods A total of 264 patients with acute anterior circulation-large vessel occlusion cerebral infarction,who were admitted to the Shanghai Changhai hospital to receive treatment from January 2020 to January 2023,were selected for this study.Mechanical thrombectomy was carried out in all the patients,and DSA flat head CT examination was performed 24 hours after operation.According to whether the postoperative DSA plate head CT scan showed high-density shadow or not,the patients were divided into observation group(showing high-density shadow,n=176)and control group(showing no high-density shadow,n=88).The clinical data,therapeutic regimen,and intracranial hemorrhage within 24 hours after operation were compared between the two groups.Taking head CT results as the standard,the clinical value of DSA flat head CT scan performed immediately after operation in predicting symptomatic intracranial hemorrhage occurring within 24 hours after operation was evaluated.Results Among the 264 patients with acute anterior circulation-large vessel occlusion cerebral infarction,118 patients developed intracranial hemorrhage within 24 hours after operation,including 24 patients(20.34％)having symptomatic intracranial hemorrhage.No statistically significant differences in clinical data and therapeutic regimen existed between the two groups(P＞0.05).The sensitivity,specificity and accuracy of DSA flat head CT scan performed immediately after operation in predicting intracranial hemorrhage occurring within 24 hours after operation in the observation group were 97.46％,58.22％and 75.76％respectively.The detection rate of symptomatic intracranial hemorrhage occurring within 24 hours after operation in the observation group was higher than that in the control group,the difference between the two groups were statistically significant(P＜0.05).The sensitivity,specificity and accuracy of DSA flat head CT scan performed immediately after operation in predicting symptomatic intracranial hemorrhage occurring within 24 hours after operation were 87.50％,57.48％and 40.15％respectively.The sensitivity,specificity and accuracy of DSA flat head CT scan in predicting the transformation of cerebral hemorrhage were 95.67％,63.12％and 80.23％respectively.Conclusion In patients with acute anterior circulation-large vessel occlusion cerebral infarction,who develop intracranial hemorrhage within 24 hours after mechanical thrombectomy,DSA flat head CT scan performed immediately after operation often shows high-density shadow,which is very helpful in predicting the risk of postoperative intracranial hemorrhage,the clinicians should make an early diagnosis and response to a possible symptomatic intracranial hemorrhage.

Objective:To investigate the efficacy of fibrosis-4 index (FIB-4), NAFLD fibrosis score (NFS), aspartate aminotransferase to platelet count ratio (APRI), liver stiffness value (LSM), and Agile 3+ score and their combined model in predicting advanced-stage liver fibrosis in patients with chronic hepatitis B (CHB) combined with metabolic-associated fatty liver disease (MAFLD).Methods:A multicenter retrospective cohort study was conducted on the BMOVE population.Nine hundred twenty CHB cases combined with MAFLD who underwent liver biopsy at seven medical centers in China from April 2006 to December 2023 were included. The patients were divided into advanced-stage liver fibrosis (159 cases) and non-advanced-stage liver fibrosis (761 cases) according to the Scheuer's scoring system.The area under the receiver operating characteristic curve (AUROC), decision curve, and calibration curve analysis were used to evaluate the efficacy of the firbrosis-4 index (FIB-4) score, NFS score, APRI index, LSM, and Agile 3+ score and their combined model in predicting advanced-stage fibrosis. The liver fibrosis grade of all patients was diagnosed by liver biopsy. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of each scoring model and combined model, as well as the proportion of correctly classified patients, were calculated based on different cutoff values.Results:AUROC analysis showed that Agile 3+ (0.814, 95% CI: 0.787-0.838) and LSM (0.805, 95% CI: 0.778-0.829) had similar accuracy and were superior to FIB-4 (0.721, 95% CI: 0.691-0.749), NFS (0.687, 95% CI: 0.656-0.716) and APRI ( 0.689, 95% CI: 0.658-0.718); however, HBV DNA level and HBV e antigen status had no effect on this outcome. Decision curve analysis showed that interventions based on LSM and Agile 3+ had provided higher net benefits compared with serological scores. Calibration curves showed that Agile 3+ had better predicitive accuracy than all other models. Agile 3+ had the highest PPV (0.54), minimal uncertainty interval (11.6%), and the highest proportion of correctly classified patients (76%); followed by LSM (PPV: 0.43, uncertainty interval: 15.5%, correct classification rate: 66%), and FIB-4 (PPV: 0.42, uncertainty interval: 26.1%, correct classification rate: 62.6%) in terms of identifying advanced-stage liver fibrosis. Combined model analysis demonstrated that FIB-4 combined with Agile 3+ had improved the correct classification rate and reduced the proportion of missed patients compared with FIB-4 combined with LSM. Conclusion:The Agile 3+ score is superior than LSM, FIB-4, NFS, and APRI index at identifying advanced-stage fibrosis in patients with CHB combined with MAFLD. This study supports the use of FIB-4 index combined with Agile 3+ for risk stratification in patients with CHB combined with MAFLD.
