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.
3.Longitudinal cohort study on pubertal development trajectories of testicular and breast development among children
Chinese Journal of School Health 2026;47(3):408-412
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.

Shift work, as a form of non-conventional work schedule, significantly increases the risk of vascular aging and related diseases due to circadian rhythm disruption, sleep disturbances, and unhealthy lifestyle behaviors. This review systematically summarized the mechanisms and epidemiological evidence linking shift work to vascular aging. Available studies indicated that shift work disrupts the rhythmic expression of core circadian clock genes (e.g., BMAL1, CLOCK, PER, CRY), leading to dysregulated glucose and lipid metabolism, enhanced oxidative stress, chronic inflammation, and altered diurnal blood pressure patterns, thereby directly impairing endothelial function and accelerating arterial stiffness. Sleep deprivation and fragmentation further reduce nitric oxide bioavailability and promote endothelin-1 secretion, exacerbating vascular constriction and inflammatory responses. Existing epidemiological data show that shift workers exhibit higher prevalence of hypertension, metabolic syndrome, and atherosclerosis compared with non-shift workers, accompanied by abnormal vascular function indicators such as pulse wave velocity and carotid intima-media thickness. Additionally, unhealthy dietary habits, psychological stress, and sedentary behavior in shift workers synergistically contribute to vascular aging. This review aims to provide a theoretical basis for the pathological link between shift work and vascular aging and to inform public health policy formulation and occupational health management.

OBJECTIVE To investigate the improvement effects and mechanism of Zhichi suanzaoren decoction (ZSD) on hippocampal oxidative stress injury in hippocampal neurons of mice with perimenopausal insomnia. METHODS The potential targets of active ingredients in ZSD were predicted using TCMSP and TCMIP databases; the targets related to insomnia were searched through GeneCards, OMIM and DisGeNET databases; protein-protein interaction network of intersecting targets of ZSD ingredients and insomnia was constructed; Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were conducted on key targets. Sixty mice were divided into sham operation group, model group, ZSD low-, medium-, and high-dose groups (11, 22, and 33 g/kg), and eszopiclone group (positive control, 1 mg/kg). Except for sham operation group, the perimenopausal insomnia model was constructed by ovariectomy (OVX) in the other groups. After successful modeling, mice in each group were gavaged with normal saline or the corresponding drug solution, once a day, for three consecutive weeks. The sleep status of mice was evaluated through the pentobarbital sodium sleep synergy experiment, and the pathological changes of hippocampal neurons and the expressions of related genes and proteins in mice were observed by HE staining, immunohistochemistry staining, immunofluorescence staining, transcriptome sequencing technology and Western blot. RESULTS The results of network pharmacology showed that there were 296 intersection targets between ZSD and perimenopausal insomnia. Protein kinase B1 (Akt1) was a key target for treating insomnia with ZSD. After administration of ZSD, the sleep latency of mice was shortened, the sleep duration was prolonged significantly, and the mean optical density value of neuron-specific nuclear protein in the hippocampal CA1 region was significantly increased (P<0.01). Additionally, hippocampal neuron damage in OVX mice was significantly alleviated. The results of transcriptome sequencing showed that ZSD significantly upregulated the transcriptional levels of Nfe2l2 gene in hippocampal tissue of OVX mice (P<0.05). After administration of ZSD, protein expressions of nuclear factor E2 related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in hippocampal tissue of OVX mice, as well as the phosphorylated Akt level, were increased significantly (P<0.01). CONCLUSIONS ZSD can ameliorate hippocampal oxidative stress injury of hippocampal neurons in perimenopausal insomnia mice by activating the Akt/Nrf2/HO-1 signaling pathway.

OBJECTIVES:
This study aims to evaluate the changes in the mandibular canal following the treatment of large odontogenic keratocysts through decompression and curettage, providing a theoretical basis for sequential treatment.
METHODS:
Twenty patients were selected for each decompression and curettage treatment of large odontogenic keratocysts in the mandible. Postoperative follow-up with was conducted every three months, during which cone beam computed tomography (CBCT) scans were performed. Then, the data were imported into MIMICS software to observe 3D changes in the position and structure of the mandibular nerve canal, followed by a comparative analysis.
RESULTS:
The total displacement of the mandibular canal was (1.89±0.21) mm on the decompression side and (0.80±0.19) mm on the curettage side. Vertically, the displacement range of the mandibular canal on the decompression side (M=1.03, SD=0.17) was larger than on the curettage side (M=0.52, SD=0.010) within nine months post-operation. In the buccal-lingual direction, the ratio of the thickness of the buccal plate to the lingual plate gradually increased with time. The amount of bone reconstruction at the part of the mandibular nerve canal closest to the cyst was (1.75±0.15) mm on the decompression side and (1.45±0.09) mm on the curettage side after nine months.
CONCLUSIONS
The mandibular nerve canal showed varying degrees of recovery and "relocation" after two surgical procedures. Osteogenesis around the mandibular nerve canal was more remarkable after decompression than after curettage. Therefore, for large odontogenic keratocyst, decompression is recommended as the initial treatment, followed by secondary curettage nine months later.

OBJECTIVES:
This study aims to analyze the biomechanics of three kinds of rigid internal fixation methods for condylar head fractures.
METHODS:
A three dimensional finite element model of the normal mandible was constructed. It was then used to prepare condylar head fracture finite element model and three kinds of rigid internal fixation finite element model (unilateral tension screw, bilateral tension screw, tension screw+titanium plate). The mechanical characteristics and changes of the mandible condyle under the same mechanical conditions were compared among the three different rigid internal fixation methods.
RESULTS:
The maximum equivalent stress and displacement of the non-free end of condyle under the rigid internal fixation method of unilateral tension screw were 71.03 MPa and 4.72 mm, respectively. The maximum equivalent stress and displacement of the free end of condyle were 78.45 MPa and 4.50 mm, respectively. The maximum stress of fracture suture was 3.27 MPa. The maximum equivalent stress and displacement of the non-free end of condyle under the rigid internal fixation method of bilateral tension screw were 70.52 MPa and 4.00 mm, respectively. The maximum equivalent stress and displacement of the free end of condyle were 72.49 MPa and 3.85 mm, respectively. The maximum stress of fracture suture was 2.33 MPa. The maximum equivalent stress and maximum displacement of the non-free end of condyle under the rigid internal fixation method of tension screw+titanium plate were 67.26 MPa and 2.66 mm, respectively. The maximum equivalent stress and maximum displacement of the free end of condyle were 69.66 MPa and 2.50 mm, respectively. The maximum stress of fracture suture was 2.18 MPa.
CONCLUSIONS
The tension screw+titanium plate rigid internal fixation method is the most conducive to biomechanical distribution for condylar head fractures.
