With the deep integration of tumor diagnosis and treatment technologies and critical care medicine, oncology critical care has emerged as an innovative interdisciplinary field, whose standardized development is crucial for improving the prognosis of cancer patients. Based on complex system theory and incorporating cutting-edge clinical practices, this paper systematically elaborates on five core principles for promoting the high-quality development of oncology critical care: complex system thinking, value-based healthcare, interdisciplinary integration, spatiotemporal holism, and humanistic experience. These five principles provide a top-level design framework for the discipline in terms of conceptual understanding, comprehensive management, developmental paradigms, clinical treatment, and service models. They aim to establish a patient-centered oncology critical care system that balances medical quality and efficiency, ultimately maximizing patient survival benefits across their entire life cycle.

Objective: To characterize longitudinal trajectories of testicular development in boys and breast development in girls, so as to provide reference data for understanding patterns of pubertal sexual maturation. Methods: Based on the Shanghai Pudong New Area Cohort Study on Growth, Development and Health in Children and Adolescents, a baseline survey was conducted in 2020 using a mult stage cluster random sampling method. A total of 2 184 children who completed all follow ups during the primary school period from 13 elementary schools in Pudong New Area,Shanghai,with annual follow ups during 2021-2025. Testicular volume and Tanner stage of breast development were assessed by professional physicians using standardized visual inspection and palpation. The age distribution of testicular volume and breast development was fitted by using cumulative link mixed models and Turnbull s nonparametric maximum likelihood estimation method. Results: Median ages for testicular volumes of 2, 3, 4 and 5 mL in boys were 7.07, 9.24, 10.29, and 11.57 years old, respectively. Median ages for Tanner breast stages Ⅱ, Ⅲ, Ⅳ, and Ⅴ in girls were 8.55 , 10.17, 11.18, and 13.78 years old, respectively. Based on overweight and obesity, stratified analysis showed that earlier pubertal onset among overweight/obesity children, and the key milestones for pubertal initiation were testicular volume reaching 4 mL in boys and breast Tanner II in girls for 10.29, 10.83; 8.18, 9.00 years. Conclusion Overweight and obesity are associated with earlier pubertal initiation,but there are certain gender and developmental stage specific patterns.

ObjectiveThis study systematically analyzed the arginine metabolic dysregulation in the rat model of heart failure （HF）， providing a modern scientific basis for elucidating the pathogenesis of HF and offering new insights for the prevention and treatment of HF with traditional Chinese medicine （TCM）. MethodsA thoracotomy was performed to ligate the left anterior descending coronary artery of rats， which induced acute myocardial ischemia and thus led to the development of post-myocardial infarction heart failure. The rats were divided into a sham surgery group and a model group， with eight rats in each group. Serum targeted metabolomics analysis was performed using ultra-performance liquid chromatography-triple quadrupole mass spectrometry （UPLC-TQ-S）， and the spatial distribution of metabolites in cardiac tissue was observed using airflow-assisted desorption electrospray ionizationmass spectrometry imaging （AFADESI-MSI）. Targets associated with HF and arginine metabolism were screened from databases including GeneCards and the Gene Expression Omnibus （GEO）， a protein-protein interaction （PPI） network was constructed， and enrichment analysis of the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway and Gene Ontology （GO） was performed. Finally， molecular docking was conducted to verify the binding between core metabolic components and key targets， and potential TCMs were predicted based on the core pathways and targets. ResultsCompared with the sham surgery group， the levels of arginine and citrulline in the serum of model rats were significantly decreased （P<0.01）， while those of proline， ornithine， creatine， creatinine and glutamate were significantly increased （P<0.05， P<0.01）. Cardiac mass spectrometry imaging showed a decreased abundance of arginine in the local myocardial tissue. Bioinformatics analysis identified 24 core functional targets， such as the angiotensin-converting enzyme （ACE）， neuronal nitric oxide synthase （NOS1）， 5-hydroxytryptamine receptor 2A （HTR2A）， and epidermal growth factor receptor （EGFR）， and enrichment analysis indicated that these targets were significantly involved in the calcium signaling pathway， neuroactive ligand-receptor interactions， and phosphatidylinositol signaling pathway. Molecular docking confirmed strong binding activities between arginine， citrulline and HTR2A， as well as between creatine， creatinine and EGFR. Based on pathway-target prediction， potential TCM interventions， such as ginseng and magnolia， were identified. ConclusionThis study revealed characteristic arginine metabolic disorder in HF， and the core targets of HF were closely associated with the phosphatidylinositol signaling pathway. It provides a modern biological interpretation of the pathogenesis of HF in TCM from the perspectives of metabolites and signaling pathways， and offers valuable insights for targeted therapy of HF and the development of TCM.

OBJECTIVE: To summarize the research and clinical application progress of foot lengthening surgery. METHODS: Relevant research literature on foot lengthening surgery in recent years at home and abroad was reviewed, and a summary was made from aspects such as the types of lengthening surgery, the types of foot diseases treated by clinical application, effectiveness, and complications. RESULTS: Bone defects and shortening deformities of the foot are relatively common clinically. As an innovative treatment method, foot lengthening surgery has gradually attracted attention, mainly including the Ilizarov technique and one-stage bone grafting lengthening surgery. The former promotes bone regeneration based on the tension-stress principle and is widely used in the treatment of calcaneal defects and congenital metatarsal brachymetatarsia, achieving good curative effects. However, there are also complications such as pin-tract infection, joint stiffness and contracture, non-union and delayed union of bone, re-fracture, and alignment deviation. The latter has a short treatment cycle, but the lengthening length is limited. Bone graft resorption and soft tissue complications are its main complications. CONCLUSION Foot lengthening surgery will develop towards the direction of personalization, intelligence, and precision. With the help of multi-center research, biological materials, and intelligent technologies, the effectiveness and safety will be further improved to better restore the function and appearance of the foot.

In current clinical practice, various dermal templates and skin substitutes are used to enhance wound healing. However, the role of wound commensal microbiome in regulating scaffold performance and the healing process remains unclear. In this study, we investigated the influence of both natural and synthetic scaffolds on the wound commensal microbiome and wound repair in three distinct models including diabetic wounds, burn injuries, and germ-free (GF) wounds. Remarkably, synthetic electrospun polycaprolactone (PCL) scaffolds were observed to positively promote microbiome diversity, leading to enhanced diabetic wound healing compared to the natural scaffolds Integra® (INT) and MatriDerm® (MAD). In contrast, both natural and synthetic scaffolds exhibited comparable effects on the diversity of the microbiome and the healing of burn injuries. In GF wounds with no detectable microorganisms, a reversed healing rate was noted showing natural scaffold (MAD) accelerated wound repair compared to the open or the synthetic scaffold (PCL) treatment. Furthermore, the response of the wound commensal microbiome to PCL scaffolds appears pivotal in promoting anti-inflammatory factors during diabetic wound healing. Our results emphasize that the wound commensal microbiome, mediated by different scaffolds plays an important role in the wound healing process.

Objective To explore the prognostic value of combined serum oxidized low-density lipoprotein(ox-LDL),remnant cholesterol(RC)and neutrophil-to-lymphocyte ratio(NLR)tests for clinical prognosis in patients with intracranial atherosclerotic stenosis(ICAS).Methods Patients with acute cerebral infarction were admitted to Cangzhou Central Hospital from June 2022 to December 2023 and diagnosed with ICAS by head MRI.A clinical diagnosis was selected(observation group,n=160).According to the modified Rankin scale(mRS)score,they were separated into a good prognosis group(mRS 0～2 points,n=52)and a poor prognosis group(mRS≥3 points,n=108).160 healthy volunteers who underwent physical examinations were used as a reference group.Magnetic particle immunochromatography was applied to detect serum ox-LDL levels.Clinical data of patients were collected,and the levels of RC and NLR were calculated.The Spearman method was used to analyze the correlation between serum ox-LDL,RC,NLR levels and mRS scores.Logistic regression was applied to analyze the factors influencing prognosis in ICAS patients.Receiver operating characteristic curve(ROC)was used to analyze the predictive value of serum ox-LDL,RC and NLR levels for the prognosis of ICAS patients.Results Compared with reference group,the serum levels of ox-LDL(53.65±8.35 U/L vs 33.23±6.42 U/L),RC(0.82±0.15 mmol/L vs 0.52±0.13 mmol/L)and NLR(2.84±0.38 vs 1.95±0.26)in observation group were obviously increased,and the differences were statistically significant(t=24.523,65.079,62.911,all P<0.05).The serum levels of ox-LDL(57.52±8.72 U/L),RC(0.84±0.14 mmol/L)and NLR(3.02±0.45)in the poor prognosis group were higher than those in the good prognosis group(45.62±6.63 U/L,0.79±0.12 mmol/L,2.48±0.36),and the differences were statistically significant(t=8.699,8.507,7.562,all P＜0.05),and there were differences in TC,LDL-C,HDL-C levels and mRS scores between the two groups,and the differences were statistically significant(t=15.755～27.072,all P<0.05).The serum levels of ox-LDL,RC,NLR were positively correlated with mRS scores(r=0.612,0.623,0.653,all P<0.05).The levels of TC,LDL-C,HDL-C,ox-LDL,RC and NLR were all factors that affected the prognosis of ICAS(all P<0.05).The AUC of serum ox-LDL,RC and NLR for predicting prognosis in ICAS patients were 0.894(0.835～0.937),0.860(0.797～0.910)and 0.817(0.748～0.874),respectively.The combined AUC(95%CI)of the three was 0.965(0.923～0.987),the combination of the three was more valuable than predicting serum ox-LDL,RC and NLR alone(Z=3.030,3.969,4.839,all P<0.05).Conclusion The serum levels of ox-LDL,RC and NLR in ICAS patients have all increased and are positively correlated with mRs scores.The three have predictive value for the prognosis of ICAS patients,and the combined detection of the three has higher clinical value.

Objective To investigate the regulation of synaptic plasticity by cannabinoid receptor 1(CB1R)and its effects on autism spectrum disorder(ASD)-like behavior.Methods CB1R-knockout(KO)mice and valproic acid(VPA)-induced ASD model mice(VPA mice)were used as study subjects.Behavioral experiments were used to assess the effects of CB1R on ASD-like behavior in mice,neuronal structural integrity and dendritic density were detected by microtubule-associated protein 2(MAP2)staining experiments,and the expression of synapse-associated proteins was detected by Western blot,to assess the effects of CB1R on synaptic plasticity.Results Behavioral result showed that VPA mice demonstrated significant ASD-like behavior,while CB1R-/-mice spent a significantly smaller proportion of residence time in the central region of the open field(P＜0.0001),showed significant increases in the number of marbles buried and self-grooming time(P＜0.01),significantly less time spent socializing with unfamiliar mice 2 and exploring unfamiliar objects(P＜0.001),and significantly more time exploring old objects(P＜0.05).The relative dwelling time was significantly reduced in CB1R+/-mice(P＜0.001),and the number of marbles buried and self-grooming time were significantly increased(P＜0.05).Synaptic plasticity assays revealed significant synaptic plasticity impairment in VPA mice.Hippocampal MAP2-positive neuron densities were significantly reduced in CB1R-/-and CB1R+/-mice,and expression levels of synapsin-1 were significantly increased(P＜0.05).Conclusions CB1R KO leads to ASD-like behavior such as anxiety and repetitive stereotyped behavior,social and cognitive impairments,as well as neuronal damage,dendritic dysplasia and disrupted synaptic protein expression in mice,suggesting that CB1R is involved in regulating synaptic plasticity as a pathological mechanism for the development of ASD-like behavior.
