Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

OBJECTIVES: This study investigated the effects of a polycaprolactone (PCL)-polyethylene glycol (PEG) scaffold incorporated with concentrated growth factor (CGF) on the adhesion, proliferation, and osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs). METHODS: The PCL-PEG-CGF composite scaffold was fabricated using an immersion and freeze-drying technique. Its microstructure, mechanical properties, and biocompatibility were systematically characterized. The hPDLSCs were isolated through enzymatic digestion, and the hPDLSCs were identified through flow cytometry. Third-passage hPDLSCs were seeded onto the composite scaffolds, and their adhesion, proliferation and osteogenic differentiation were assessed using CCK-8 assays, 4',6-diamidino-2-phenylindole (DAPI) staining, alkaline phosphatase (ALP) staining, alizarin red staining, and Western blot analysis of osteogenesis-related proteins [Runt-related transcription factor 2 (Runx2), ALP, and morphogenetic protein 2 (BMP2)]. RESULTS: Scanning electron microscopy revealed that the PCL-PEG-CGF composite scaffold exhibited a honeycomb-like structure with heterogeneous pore sizes. The composite scaffold exhibited excellent hydrophilicity, as evidenced by a contact angle (θ) approaching 0° within 6 s. Its elastic modulus was measured at (4.590 0±0.149 3) MPa, with comparable hydrophilicity, fracture tensile strength, and fracture elongation to PCL-PEG scaffold. The hPDLSCs exhibited significantly improved adhesion to the PCL-PEG-CGF composite scaffold compared with the PCL-PEG scaffold (P<0.01). Additionally, cell proliferation was markedly improved in all the experimental groups on days 3, 5, and 7 (P<0.01), and statistically significant differences were found between the PCL-PEG-CGF group and other groups (P<0.01). The PCL-PEG-CGF group showed significantly elevated ALP activity (P<0.05), increased mineralization nodule formation, and upregulated expression of osteogenic-related proteins (Runx2, BMP2 and ALP; P<0.05). CONCLUSIONS The PCL-PEG-CGF composite scaffold exhibited excellent mechanical properties and biocompatibility, enhancing the adhesion and proliferation of hPDLSCs and promoting their osteogenic differentiation by upregulating osteogenic-related proteins.

Ubiquitination is a crucial post-translational modification that is extensively involved in the regulation of protein activity,signal transduction,and the maintenance of genomic stability.As an important member of the deubiquitinating enzyme(DUB)family,ubiquitin-specific protease 11(USP11)dynamically regulates the stability and function of key tumor proteins by targeting specific substrates for deubiquitination.This,in turn,influences various biological behaviors of tumor cells,including proliferation,apoptosis,migration,invasion,metastasis,and drug resistance,ultimately exhibiting a dual role in either promoting or inhibiting cancer.This article systematically reviewed the relevant research progress on the role of USP11 in tumorigenesis and development and provided an in-depth analysis of the specific mechanisms by which USP11 participates in cellular biological behav-iors,aiming to offer a theoretical basis for the future development of small-molecule inhibitors targeting USP11,the formulation of combination drug strategies,and the identification of effective biomarkers.

Periodontal tissue diseases are common oral diseases.Although traditional mechanical de-bridement therapy can control inflammation,it is difficult to achieve complete regeneration of periodontal tis-sues.In recent years,research and applications of combining 3D bioprinting technology with mesenchymal stem cells(MSCs)have rapidly developed in the field of periodontal tissue regeneration.This combined ap-proach provides a novel strategy for periodontal tissue regeneration by constructing a biomimetic microenvi-ronment and promoting cell proliferation and differentiation.This article reviewed the types of 3D bioprinting technology,the characteristics of bioink materials,the sources of MSCs,and their application progress in peri-odontal tissue regeneration.Additionally,it analyzed the current technical bottlenecks and clinical translation challenges,aiming to provide references for future research and clinical applications.

Objective: To analyze the safety and effectiveness of different types of stents with the treatment of vertebraebasilar artery dissection aneurysms(VBADA). Methods : The clinical data of 80 patients with VBADA treated by intravascular intervention in the First Hospital of University of Science and Technology of China(Anhui Provincial Hospital) from February 2018 to November 2023 were retrospectively analyzed. Patients were divided into laser engraved stent group(n=34) and braided stent group(n=46) based on the type of stent used. O′Kelly-Marotta(OKM) grade was used to evaluate the embolization effect of aneurysms in DSA images, and a modified Rankin Scale(mRS) score was used to evaluate the clinical prognosis of patients. The baseline data, aneurysm characteristics, intraoperative and perioperative treatment details and postoperative follow-up details between the two groups were compared. Results : There was no significant difference in baseline data, mRS score, ischemic and hemorrhage complications and mortality between the two groups(allP>0.05). Compared with the laser engraved stent group, the mean diameter of aneurysms was larger(P<0.000 1) and the proportion of ruptured aneurysm(P<0.01), parent artery stenosis and beaded vascular lesions(P<0.05) and branch artery dissecting aneurysm were higher(P<0.01) in the braided stent group. Conversely, the proportion of coil-assisted embolization(P<0.000 1) and the immediate aneurysm occlusion rate(OKM C and D)(P<0.000 1) were lower. Finally, 21 patients were obtained by controlling for maximum diameter of aneurysms and whether coil-assisted embolization, the aneurysm occlusion rate half a year later in the braided stent group was higher than that in the laser engraved stent group(P<0.05), but the recurrence rate of postoperative aneurysm was lower than that of laser engraved stent group(P<0.05). It was worth noting that the cure rate and vascular remodeling rate of middle-large size VBADA which the maximum diameter being over 15 mm in the braided stent group reached 72.2%, and the whole effect was ideal. Conclusion Braided stents are relatively safe and effective in the treatment of VBADA and are significantly better than laser engraved stents in reducing VBADA recurrence and remodeling lesion vessels without increasing postoperative complication.

Objective To explore the value of multi-parameter spectral CT for differentiating grade G2-3 pancreatic neuroendocrine tumor(pNET)and pancreatic neuroendocrine carcinoma(pNEC).Methods Preoperative double-layer detector spectral CT(DLCT)data of 35 patients with pNET(pNET group,including 25 cases of G2 grade and 10 cases of G3 grade)and 17 patients with pNEC(pNEC group)were retrospectively analyzed.Conventional CT and spectral CT parameters were compared between groups,and those being significant different between groups according to univariate analysis were respectively incorporated into multivariate logistic regression to select the independent predictors for identifying grade G2-3 pNET and pNEC.Conventional CT model and spectral CT model were constructed,and the combined model was constructed based on the two.The efficacy of each model for distinguishing grade G2-3 pNET and pNEC was evaluated.Results CT values of lesions during venous phase(OR=0.939,P=0.025)and vascular invasion(OR=5.049,P=0.027)shown on conventional CT were both independent predictors,and conventional CT model was constructed,its area under the curve(AUC)for distinguishing grade G2-3 pNET and pNEC was 0.808.Normalized iodine concentration during venous phase(OR=0.603)and normalized effective atomic number during venous phase(OR=0.847)on spectral CT were both independent predictors(both P＜0.05),and spectral CT model was constructed.The AUC of spectral CT model was 0.894,higher than that of conventional CT model(Z=2.127,P=0.033).The AUC of combined model was 0.924,higher than that of conventional CT model(Z=2.302,P=0.021)but not significantly different with that of spectral CT model(Z=0.827,P=0.408).Conclusion Multi-parameter spectral CT could effectively differentiate grade G2-G3 grade pNET and pNEC.
