Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

With the rapid development of artificial intelligence, computational pathology has been seamlessly integrated into the entire clinical workflow, which encompasses diagnosis, treatment, prognosis, and biomarker discovery. This integration has significantly enhanced clinical accuracy and efficiency while reducing the workload for clinicians. Traditionally, research in this field has depended on the collection and labeling of large datasets for specific tasks, followed by the development of task-specific computational pathology models. However, this approach is labor intensive and does not scale efficiently for open-set identification or rare diseases. Given the diversity of clinical tasks, training individual models from scratch to address the whole spectrum of clinical tasks in the pathology workflow is impractical, which highlights the urgent need to transition from task-specific models to foundation models (FMs). In recent years, pathological FMs have proliferated. These FMs can be classified into three categories, namely, pathology image FMs, pathology image-text FMs, and pathology image-gene FMs, each of which results in distinct functionalities and application scenarios. This review provides an overview of the latest research advancements in pathological FMs, with a particular emphasis on their applications in oncology. The key challenges and opportunities presented by pathological FMs in precision oncology are also explored.

Objective: To explore the mechanism of action of Zangjiangzhi capsule (ZJZC) in treating hyperlipidemia (HLP). Methods: The components of ZJZC were analyzed and identified using ultra-high performance liquid chromatography with Q-Exactive Orbitrap tandem mass spectrometry (UHPLC-Q-Exactive-Orbitrap-MS/MS). Network pharmacology analysis was used to explore the mechanism of action of ZJZC in HLP treatment. The SwissTargetPrediction database was used to predict compound targets, and GeneCards, DisGeNet, OMIM, and DRUGBANK databases were used to identify HLP-related targets. Protein–protein interaction diagrams were constructed using the STRING database. The targets were subjected to gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The “herb-ingredient-target” network was visualized using Cytoscape. Preliminary validation was performed using molecular docking and enzyme-linked immunosorbent assay. Results: Ninety compounds were identified in ZJZC, including 34 flavonoids, 12 phenols, 10 terpenoids, 10 alkaloids, 8 organic acids, 8 anthraquinones, and 9 other compounds. In total, 904 targets were identified for these compounds. Among them, 158 targets intersected with the HLP target network. Network pharmacology analysis showed that MAPK1, PPAR-α, RXRA, HSP90AA1, PIK3R1, AKT1, PIK3CA, IL6, TNF, and ESR1 are the key targets of action. KEGG enrichment analysis identified 164 pathways. Among these, the AGE-RAGE signaling pathway in diabetic complications, lipid and atherosclerosis pathways, regulation of lipids in adipocytes, and insulin resistance are related to HLP. Molecular docking showed good affinity between the key targets and ingredients. Further, ZJZC treatment in mice resulted in lower expression of MAPK1 protein and increased expression of PPAR-α protein, which have been shown to be strongly associated with HLP. Conclusions This study showed that ZJZC contains various active ingredients and can modulate multiple targets and pathways associated with HLP, providing evidence at the molecular level for its clinical application in the treatment of HLP.

Background: Bushen Zhuanggu Formula (BZF), derived from the classic Yougui Pills, has shown favorable clinical efficacy in treating advanced nontraumatic osteonecrosis of the femoral head (NONFH), particularly by promoting bone repair. However, its underlying mechanisms remain unclear. Objective: This study aimed to explore the mechanisms by which BZF promotes bone repair in advanced NONFH. Materials and methods: A total of 518 potential BZF targets were identified from the ETCM v2.0 database. Transcriptomic profiling of clinical cohorts revealed 485 differentially expressed genes in advanced NONFH patients compared to healthy controls. A drug target-disease gene interaction network was constructed to identify candidate BZF targets involved in NONFH pathogenesis. In vivo experiments were conducted to validate the effects of BZF in a rat model of advanced NONFH. Results: Network analysis identified key pathways associated with blood circulation obstruction, immune-inflammatory imbalance, and abnormal bone metabolism. Protein kinase C alpha (PKCA), Ras proto-oncogene (RAS), mitogen-activated protein kinase 3(ERK), ETS proto-oncogene 1 (ETS1), and receptor activator of nuclear factor-κB ligand (RANKL) formed a signaling axis implicated in NONFH pathogenesis. BZF treatment alleviated joint inflammation, preserved trabecular bone morphology, reduced bone loss, and promoted bone repair. Mechanistically, BZF significantly downregulated the expression of PKCA, RAS, ERK, ETS1, and RANKL, improved blood circulation, and inhibited osteoclast activation while promoting osteoblast activation. Conclusion: BZF may promote bone repair in advanced NONFH by enhancing blood circulation and modulating the PKC-RAS-ERK-ETS1-RANKL signaling axis, thereby reversing dysregulated bone metabolism.

OBJECTIVE: To investigate the effectiveness of using 3 hollow compression screws combined with 1 screw off-axis fixation under the guidance of three-dimensional (3D) printed guide plate with mortise-tenon joint structure (mortise-tenon joint plate) for the treatment of Pauwels type Ⅲ femoral neck fractures. METHODS: A clinical data of 78 patients with Pauwels type Ⅲ femoral neck fractures, who were admitted between August 2022 and August 2023 and met the selection criteria, was retrospectively analyzed. The operations were assisted with mortise-tenon joint plates in 26 cases (mortise-tenon joint plate group) and traditional guide plates in 28 cases (traditional plate group), and without guide plates in 24 cases (control group). There was no significant difference in the baseline data of gender, age, body mass index, cause of injury, and fracture side between groups ( P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, incision length, incidence of postoperative deep vein thrombosis of lower extremity, pain visual analogue scale (VAS) score at 1 week after operation, and Harris score of hip joint at 3 months after operation were recorded and compared. X-ray re-examination was taken to check the quality of fracture reduction, fracture healing, and the shortening length of the femoral neck at 3 months after operation, and the incidences of internal fixation failure and osteonecrosis of the femoral head during operation. RESULTS: Compared with the control group, the operation time, intraoperative blood loss, and frequency of intraoperative fluoroscopy reduced in the two plate groups, and the quality of fracture reduction was better, but the incision was longer, and the differences were significant ( P<0.05). The operation time and intraoperative blood loss were significantly higher in the traditional plate group than in the mortise-tenon joint plate group ( P<0.05), the incision was significantly longer ( P<0.05); and the difference in fracture reduction quality and the frequency of intraoperative fluoroscopy was not significant between two plate groups ( P>0.05). There was 1 case of deep vein thrombosis of lower extremity in the traditional plate group and 1 case in the control group, while there was no thrombosis in the mortise-tenon joint plate group. There was no significant difference in the incidence between groups ( P>0.05). All patients were followed up 12-15 months (mean, 13 months). There was no significant difference in VAS score at 1 week and Harris score at 3 months between groups ( P>0.05). Compared with the control group, the fracture healing time and the length of femoral neck shortening at 3 months after operation were significantly shorter in the two plate groups ( P<0.05). There was no significant difference between the two plate groups ( P>0.05). There was no significant difference in the incidences of non-union fractures, osteonecrosis of the femoral head, or internal fixation failure between groups ( P>0.05). CONCLUSION For Pauwels type Ⅲ femoral neck fractures, the use of 3D printed guide plate assisted reduction and fixation can shorten the fracture healing time, reduce the incidence of postoperative complications, and be more conducive to the early functional exercise of the affected limb. Compared with the traditional guide plate, the mortise-tenon joint plate can reduce the intraoperative bleeding and shorten the operation time.

At the age of 14 days, the mice in the Con+ Ast group and the Mod+ Ast group were intraperitoneally injected with Ast (20 mg/kg, once a day for 7 consecutive days), the mice in the Mod+ Ast+ LY group were intraperitoneally injected with Ast (20 mg/kg) and LY294002(30 mg/kg), the mice in Con+ NS group and Mod+ NS group were intraperitoneally injected with the same volume of 0.9% NaCl solution.The depressive-like behavior and social function were evaluated by the marble-burying test (MBT), the three-chamber social interaction test(SIT), and the forced swimming test(FST). The expression levels of proteins related to the PI3K/AKT signaling pathway in the amygdala were detected by Western blot. The immunofluorescence method was employed to determine the levels of the neurotransmitters glutamate (Glu) and γ-aminobutyric acid(GABA)in the amygdala region.Statistical analysis was carried out using GraphPad Prism 9.5.0 software, and one-way ANOVA test was utilized for comparisons among multiple groups.Results:(1)Behavioral results showed that there were statistically significant differences in the number of buried beads of the MBT, the social interaction index and social novelty preference index of the SIT, and the immobility time and first immobile state incubation period of the FST among the five groups( F=28.85, 89.23, 77.62, 91.70, 125.40, all P<0.05). The number of buried beads and immobility time in Mod+ NS group were higher than those in Con+ NS group, and first immobile state incubation period, the social interaction index and social novelty preference index were lower than those in Con+ NS group (all P<0.05). The number of buried beads and immobility time in Mod+ Ast group were lower than those in Mod+ NS group, and first immobile state incubation period, the social interaction index and social novelty preference index were higher than those in Mod+ NS group(all P<0.05). The number of buried beads and immobility time in Mod+ Ast+ LY group were higher than those in Mod+ Ast group, and first immobile state incubation period, the social interaction index and social novelty preference index were lower than those in Mod+ Ast group (all P<0.05).(2) Western blot results showed that there were statistically significant differences in p-PI3K/PI3K, p-AKT/AKT in amygdala among the five groups ( F=27.14, 25.50, both P<0.05). The expressions of p-PI3K/PI3K and p-AKT/AKT in the amygdala of Mod+ NS group were lower than those of Con+ NS group(both P<0.05).The expressions of p-PI3K/PI3K and p-AKT/AKT in amygdala of Mod+ Ast group((0.67±0.04), (0.52±0.09))were higher than those of Mod+ NS group((0.48±0.06), (0.34±0.06))(both P<0.05). The expressions of p-PI3K/PI3K and p-AKT/AKT in the amygdala of Mod+ Ast+ LY group ((0.52±0.04), (0.36±0.10))were lower than those of Mod+ Ast group(both P<0.05). (3)Immunofluorescence results showed that the number of Glu- and GABA- positive cells in the amygdala region of the five groups were significantly different( F=41.84, 37.70, both P<0.05). The number of Glu-positive cells in the amygdala of Mod+ NS group was higher than that of Con+ NS group, and the number of GABA-positive cells in Mod+ NS group was lower than that of Con+ NS group( P<0.05). The number of Glu-positive cells in the amygdala of Mod+ Ast group((54.00±8.48)cells/mm 2)was lower than that of Mod+ NS group((82.17±7.36)cells/mm 2), and the number of GABA-positive cells in Mod+ Ast group((59.20±11.22)cells/mm 2)was higher than that of Mod+ NS group((41.33±7.11)cells/mm 2) ( P<0.05). The number of Glu-positive cells in the amygdala of Mod+ Ast+ LY group((75.67±9.15)cells/mm 2) was higher than that of Mod+ Ast group, and the number of GABA-positive cells in Mod+ Ast+ LY group((43.33±4.27)cells/mm 2)was lower than that of Mod+ Ast group ( P<0.05). Conclusion:Astragaloside can ameliorate social deficits in ASD mice via modulating the PI3K/AKT signaling pathway and excitation-inhibition balance in the amygdala.

Objective To investigate the clinical value of 18F-FDG PET/CT image in assisting CT-guided puncture of pancreatic tumor.Methods One hundred and thirteen patients with pancreatic tumors were selected and then divided into 18 F-FDG PET/CT image-assisted CT-guided group(abbreviation 18F-FDG PET/CT-assisted group)(n=54)and CT-guided group(n=59)according to the different guided puncture methods.The diagnostic efficacy and safety of the two guided puncture biopsy methods were analyzed and compared.Results All patients successfully completed the biopsy.The accuracy(the agreement rate between pathological diagnosis and final clinical diagnosis),sensitivity,and complication rate of the 18F-FDG PET/CT-assisted group were 96.30％(52/54),96.15％(50/52),and 3.70％(2/54);and those of the CT-guided group were 84.75％(50/59),83.64％(46/55),and 15.25％(9/59).Ultimately,it was found that the 18F-FDG PET/CT-assisted group performed better in terms of accuracy and complications than CT-guided group,and the differences were statistically significant(x2=4.280 9,P=0.038 5;x2=5.211 4,P=0.022 4).No serious complications such as hemorrhage,abdominal infection,pancreatic fistula,intestinal fistula and so on occurred in all patients.Conclusion 18F-FDG PET/CT image in assisting CT-guided pancreatic tumor puncture possesses more efficient,precise,and safe characteristics,which is the innovation and expansion of traditional CT image-guided puncture biopsy.However,there is still improvement room in terms of economy and feasibility.
