Objective To explore the molecular mechanism by which SOS Ras/Rac guanine nucleotide exchange factor 1-intronic transcript 1(SOS1-IT1)affects enhancer of zeste homolog 2(EZH2)protein expression in endometrial cancer cells Ishikawa and RL95-2.Methods Lentiviral transfection of short hairpin RNA(shRNA)and overexpression plasmid were used in Ishikawa and RL95-2 cell lines to knock down and overexpress SOS1-IT1.The mechanism of EZH2 expression regulation was studied using Real-time PCR,Western blotting,and chromatin immunoprecipitation.Results The expression of SOS1-IT1 and EZH2 genes was positively correlated in endometrial cancer tissues.Knocking down SOS1-IT1 significantly reduces the expression of EZH2,inhibited the proliferation and migration of Ishikawa and RL95-2 cells,and could reduced the acetylation of histone H3 at position 27(H3K27)and the enrichment of CREB binding protein(CBP)in the EZH2 gene promoter region.Overexpression of SOS1-IT1 could increased the expression of EZH2 and enhance the acetylation of H3K27 and the enrichment of CBP.CBP could bind to SOS1-IT1 RNA,and this binding ability was weakened when CBP was knocked down.Conclusion SOS1-IT1 can promote the expression level of EZH2 in endometrial cancer cells Ishikawa and RL95-2 by regulating the acetylation modification level of the EZH2 gene promoter region,thereby affecting the proliferation and migration ability of endometrial cancer cells.

BACKGROUND:
A growing body of research is exploring the role of antioxidant and anti-inflammatory dietary supplements in the treatment of osteoarthritis, highlighting an increasing emphasis on non-pharmacological interventions. Although more patients are turning to supplements to manage osteoarthritis, their actual effectiveness remains uncertain.
OBJECTIVE:
This study aims to provide a comprehensive evaluation of the available evidence concerning the efficacy of various dietary supplements in osteoarthritis treatment.
SEARCH STRATEGY:
We searched PubMed, Embase, Cochrane Library and Web of Science for studies on the use of various dietary supplements in the treatment of osteoarthritis from the creation of each database until Jan 20, 2025.
INCLUSION CRITERIA:
(1) Research object: osteoarthritis. (2) Intervention measures: patients in the treatment group received dietary supplements, while the control group received placebos. (3) Research type: randomized controlled trials (RCTs).
DATA EXTRACTION AND ANALYSIS:
Two researchers independently examined the literature and retrieved data based on predefined criteria. The information gathered included the first author, year of publication, sample size, participant demographics, length of the follow-up period, intervention and control measures, and inclusion indications. RCTs comparing dietary supplements to placebo with the pain and function subscales of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) among patients with osteoarthritis were included. The optimal dietary supplement was identified based on the total ranking by summing the surface under the cumulative ranking curve (SUCRA) of these two scores. Furthermore, the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to confirm the quality of the evidence.
RESULTS:
Overall, 23 studies covering 21 dietary supplements and involving 2455 participants met the inclusion criteria. In the WOMAC pain score, the SUCRA of passion fruit peel extract was 91% (mean difference [MD]: -9.2; 95% confidence interval [CI]: [-16.0, -2.3]), followed by methylsulfonylmethane (89%), undenatured type II collagen (87%), collagen (84%), and Lanconone (82%). The SUCRA (99%) of passion fruit peel extract (MD: -41.0; 95% CI: [-66.0, -16.0]) ranked first in terms of the WOMAC function score, followed by Lanconone (95%), collagen (86%), ParActin (84%), and Lactobacillus casei strain Shirota (83%). The top three total rankings are passion fruit peel extract (95.0%), Lanconone (88.5%), and collagen (85.0%). However, the GRADE revealed low evidence quality.
CONCLUSION
Passion fruit peel extract was the best supplement for improving WOMAC pain and function scores in patients with osteoarthritis, followed by Lanconone and collagen. However, further large-scale, well designed RCTs are required to substantiate these promising findings.

Tumor-associated neutrophils(TAN)are key components of the tumor microenvironment(TME)that exert dual regulatory roles in tumor progression through highly heterogeneous functional phenotypes.This review systematically addresses the dynamic balance of TAN in pro-tumor and anti-tumor mechanisms:TAN can directly kill tumor cells or collaborate with immune cells to activate anti-tumor re-sponses;however,in contrast,they can accelerate tumor progression by promoting angiogenesis,remodeling the extracellular matrix,and mediating immune evasion.Studies have shown that the functional heterogeneity of TAN is precisely regulated by multiple signaling net-works within the TME,and that the plasticity transformation of different subsets directly influences tumor progression.In-depth analyses of TAN subset characteristics,transformation mechanisms,and their clinical relevance will provide a theoretical basis for the development of inhibitors targeting pro-tumor neutrophils as well as advance the establishment of precise patient selection strategies for TAN subtype-based immunotherapy.

Objective:To develop and assess a three-class machine learning model for predicting wild-type, 19 del, and 21 L858R mutations of the epidermal growth factor receptor (EGFR) in lung adenocarcinoma using 18F-FDG PET/CT radiomic features and clinical features. Methods:The retrospective data was collected from 703 patients (346 males, 357 females; age (64.3±9.0) years) with lung adenocarcinoma at the First People′s Hospital of Changzhou from January 2018 to June 2023. Patients were divided into the training set (563 cases) and test set (140 cases) at the ratio of 8∶2. Clinical features were selected using recursive feature elimination (RFE). Radiomic features were extracted from PET and CT images, and the optimal feature sets were selected using minimum redundancy maximum relevance (mRMR) and least absolute shrinkage and selection operator (LASSO) methods. Base models were constructed by using random forest (RF), logistic regression (LR), support vector machine (SVM), K-nearest neighbors (KNN), and multi-layer perceptron (MLP), and the stacking method was applied to establish the CT and PET ensemble models. Delong test was used to compare the AUC differences between the PET/CT combined model and the clinical + PET/CT integrated model.Results:Among 703 patients, 273 were with EGFR wild-type, 202 were with 19 del mutation, and 228 were with 21 L858R mutation. In the single-modal analysis, the AUCs of CT ensemble model in the training and test sets were 0.893 and 0.667, respectively, while the AUCs of PET ensemble model were 0.692 and 0.660. The AUC of PET/CT combined model were 0.897 in training set and 0.672 in test set. The AUC of clinical + PET/CT integrated model showed further improvement, with AUCs of 0.902 and 0.721 in training and test sets, respectively. Notably, the clinical + PET/CT integrated model outperformed PET/CT combined model in predicting wild-type EGFR (test set AUC: 0.784 vs 0.707; Z=3.28, P=0.001). Conclusion:The three-class model (clinical + PET/CT integrated model) based on 18F-FDG PET/CT radiomics and clinical features effectively predicts EGFR mutation subtypes in lung adenocarcinoma.

With the rapid development of generative adversarial networks (GAN), learning the mapping between CT and PET images enables cross-modality generation. This not only integrates anatomical and functional information to improve image quality, but also helps reduce the radiation exposure to some extent. Based on a review of representative GAN architectures such as conditional GAN and CycleGAN, this paper discusses their research progress and limitations in various application scenarios, including initial tumor diagnosis and staging, treatment evaluation and follow-up, as well as methods for reducing PET/CT radiation dose. Additionally, challenges related to small-sample learning, model interpretability, and cross-institutional standardization are highlighted, and the clinical application prospects of GAN-based cross-modality generation technology are explored.

Objective:To investigate the clinical efficacy of combination of a Flow-through anterolateral thigh myocutaneous flap with a contralateral great saphenous vein grafting in reconstruction of Gustilo ⅢC foot and ankle injury in emergency surgery.Methods:This retrospective study analysed the clinical data of 9 patients who were admitted in the Department of Wound Repair Surgery, Suzhou Ruihua Orthopaedic Hospital between September 2021 and October 2023. All patients were diagnosed with Gustilo ⅢC foot and ankle injury and met the predefined inclusion criteria. The average age of the patients was 45 (26-64) years. The mean of Mangled Extremity Severity Score (MESS) was 8.2 points, with a range from 5 to 10 points. The wound area after debridement ranged from 15.5 cm×6.0 cm to 24.5 cm×12.5 cm, with the vascular occlusion or defect at 4.0-20.0 (mean, 6.3) cm in length. The size of the flap was 16.5 cm×7.0 cm-25.5 cm×13.5 cm. During surgery, segments of the great saphenous vein were excised in the length of 5.0-21.0 cm, at an approximately 6.5 cm in length. The Flow-through anterolateral thigh myocutaneous flap was employed to reconstruct the soft tissue defect and to establish vascular connections between the anterior or posterior tibial arteries and veins, with the vessels carried by the flap. Additionally, the contralateral great saphenous vein was taken to bridge the posterior or anterior tibial arteries and veins. Follow-ups were carried out by outpatient visits, telephone calls and WeChat interviews. The flap viability, limb blood circulation, wound healing at both donor and recipient sites, as well as functional recovery of the affected limbs was observed. Sensation recovery of the flap was assessed according to the rating standard established by the British Medical Research Council (BMRC) , while the function recovery of foot and ankle was evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scale.Results:All flaps successfully survived without vascular complication. Eight affected limbs were effectively cured, while a calf that had an infection and necrosis of a long segment of tibia and fibula was amputated below-the-knee in the stage-II surgery. One of the donor sites of flap was covered with a medium-thickness skin graft from lower abdomen due to the large size of the flap, while the other donor sites were directly sutured and healed at first intention. One patient developed postoperative bone infection, which was successfully treated through re-debridement and antibiotic bone cement filling. Another patient experienced partial necrosis at the distal hallux due to a prolonged limb ischemia, and a stump repair surgery was performed. All patients were entered into the postoperative follow-up for 15.3 (6-24) months. At the final follow-up visit, satisfactory colour and texture were observed on all flaps, although minor oedema was present. Donor sites healed well and the donor limb function was not affected. Sensory evaluation rated S 2 in 5 flaps and S 3 in 3 flaps according to BMRC. Functional assessment of foot and ankle of the affected limb yielded excellent in 2 patients, good in 5 patients and fair in 1 patient according to AOFAS. Conclusion:Flow-through anterolateral thigh myocutaneous flap combined with a contralateral great saphenous vein grafting enables one-stage reconstruction for soft tissue defect and blood circulation of the affected limb. It is a good method in the treatment of Gustilo ⅢC foot and ankle injury in emergency surgery.

Objective:To investigate the role of platelet-derived zyxin in promoting tumor migration by platelets.Methods:The gene expression profile of platelets was analyzed from cancer patients by using the GEO database.Isolated platelets from wild-type(WT)and Zyx-/-mice were co-cultured with B16F10 cells labeled with green fluorescence to investigate the influence of zyxin deficiency on tumor cell migration,invasion,and wound healing.Optical microscopy was employed to evaluate the impact of zyxin deficiency on epithelial-mesenchymal transition(EMT)in B16F10 cells induced by platelets.Employing specific markers to label platelets,fluorescence confocal microscopy was utilized to investigate the impact of platelet-derived zyxin on the binding between tumor cells and platelets.And an aggregometer was employed to observe the influence of zyxin deficiency on tumor cell-induced platelet aggregation.Results:Compared to platelets from healthy volunteers,zyxin was upregulated in platelets from cancer patients.Zyx-/-mouse platelets exhibited a significant reduction in tumor cell invasion and migration,impaired wound healing,and delayed tumor cell EMT compared to WT mouse platelets.Additionally,zyxin deficiency attenuated the interaction between platelets and tumor cells,and diminished the capacity for tumor cell-induced platelet aggregation.Conclusion:Platelet-derived zyxin deficiency diminishes platelet-tumor cell interactions and weakens the ability of tumor cell-induced platelet aggregation,ultimately suppressing tumor cell migration.
