Methods: Sixty-two patients (2014–2019) were divided into the SC (n=32) and PC (n=30) groups. Clinical outcomes were evaluated using the Visual Analog Scale (VAS), modified Japanese Orthopedic Association (mJOA) score, and Neck Disability Index (NDI). Radiological parameters, including cervical lordosis (CL), fused segment angle (FSA), and disc height (DH), were assessed. Cage subsidence, adjacent segment degeneration (ASD), and other complications were also documented. The relationship between postoperative radiological changes and symptoms was also analyzed. Results: Both groups showed significant improvement in symptoms, with fusion achieved in all surgical segments. The SC group had a shorter operative time and reduced intraoperative blood loss. However, the SC group had a higher subsidence rate (16.7% vs. 5.6%, p=0.017). The PC group maintained better cervical alignment in terms of CL, FSA, and DH (p<0.05), with an increased incidence of dysphagia and ASD (p<0.05). Spearman correlation analyses showed that neither CL nor FSA loss at the 5-year follow-up was significantly associated with improvements in the mJOA, VAS, and NDI scores (p>0.05) in either group. Regression analyses indicated that subsidence or loss of lordosis did not correlate with the degree of postoperative symptoms (p<0.05). Conclusions Both SC and PC achieved sustained pain relief, neurological improvement, and solid fusion in three-level ACDF at the 5-year follow-up. SC demonstrated significant advantages in reducing dysphagia and ASD, while PC better maintained cervical alignment and segmental stability. Patient-specific factors should be used to guide implant selection. Further multicenter studies are required to validate these findings.

Objective:To explore the effects of age and gender on the sagittal spinal-pelvic parameters during the natural aging process of healthy adults.Methods:A total of 647 Chinese healthy adults who underwent health check-ups at the Second Affiliated Hospital of Zhejiang University School of Medicine and Songyang County People's Hospital, from January 2017 to September 2024 were collected. There were 277 males and 370 females, aged 18-93 years. Anteroposterior and lateral X-ray films of the whole spine were taken to evaluate the spinal-pelvic sagittal morphology. The following parameters were measured: thoracic kyphosis (TK), lumbar lordosis(LL), sacral slope (SS), pelvic incidence (PI), pelvic tilt (PT), global tilt (GT), T 1-pelvic angle (TPA), sagittal vertical axis (SVA), thoracic Cobb angle (T-Cobb), lower end vertebra of thoracic Cobb angle (T-LEV), apex vertebra of thoracic Cobb angle (T-Apex), lumbar Cobb angle (L-Cobb). Compare the differences in spine-pelvis parameters among patients of different genders and age groups (in this study, the subjects were subdivided into the 18-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-93 years groups according to the age range). Results:The results showed that GT, SVA, TPA, and PT increased with age ( P<0.05). For males aged 18-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-93 years, PT values were 8.58°±6.47°, 9.60°±5.63°, 12.65°±7.13°, 11.00°±6.99°, 13.01°±8.63°, 15.77°±8.02°, and 18.47°±10.03° respectively; for females in the same age groups, the PT values were 8.44°±6.83°, 9.00°±6.44°, 11.84°±7.35°, 12.07°±7.51°, 15.44°±9.39°, 19.26°±8.28°, and 18.17°±9.43° respectively. For males in these age groups, the global tilt (GT) values were 6.37°±7.20°, 8.77°±6.51°, 10.38°±9.07°, 8.80°±7.49°, 10.80°±8.62°, 16.07°±10.42°, and 21.99°±12.65° respectively; for females, the GT values were 4.46°±8.09°, 5.96°±7.83°, 8.17°±6.88°, 9.41°±8.03°, 9.96°±1.39°, 17.89°±9.39°, and 19.55°±12.34° respectively. The sagittal vertical axis (SVA) values for males in the age groups were -7.94±25.57 mm, -2.98±25.69 mm, -4.63±20.90 mm, -6.43±32.81 mm, 7.85±43.39 mm, 36.49±53.89 mm, and 55.57±51.10 mm respectively; for females, they were -24.12±31.35 mm, -17.49±25.12 mm, -17.88±22.72 mm, -8.25±30.91 mm, 8.80±27.45 mm, 28.67±38.22 mm, and 23.23±35.19 mm respectively. For males, the thoracic pelvic angle (TPA) values across the age groups were 4.46°±5.94°, 6.05°±5.38°, 9.58°±9.35°, 7.52°±7.64°, 11.23°±9.59°, 16.32°±12.38°, and 18.49°±11.70° respectively; for females, the TPA values were 2.72°±6.88°, 3.68°±6.26°, 7.30°±6.11°, 7.44°±6.75°, 12.64°±9.79°, 19.08°±10.39°, and 16.79°±13.19° respectively. T-Cobb, T-LEV, and T-Apex increased slowly with age ( P<0.05). The pelvic incidence (PI) remained relatively constant in males ( P>0.05), while it increased slowly with age in females ( P<0.05). Conclusions:Sagittal anteversion of the spinal-pelvis increases with age. Gender differences are reflected in specific changes in the fluctuation amplitude of certain parameters (such as PI), and the fluctuations of indicators like T-Cobb, T-LEV, and T-Apex are closely related to the natural aging process of the spine.

ObjectiveTo explore the clinical safety of Feilike Mixture （FLK） in the real world. MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21，2021 and December 25，2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved，which are distributed across 12 provinces，including one traditional Chinese medicine （TCM） hospital and 28 general hospitals. The average age among the juveniles was （4.77±3.56） years old，and the average weight was （21.81±12.97） kg. Among them，119 cases （3.92%） of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles，with 1 656 cases （54.46%）. FLK was first used in 2 016 cases （66.43%），and 142 juvenile patients had special dosages，accounting for 4.68%. Among them，92 adverse drug reactions （ADRs） occurred，including 73 cases of gastrointestinal system disorders，10 cases of metabolic and nutritional disorders，eight cases of skin and subcutaneous tissue diseases，two cases of vascular and lymphatic disorders，and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea，stool discoloration，and vomiting，and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages （the use of FLK）［odds ratio （OR） of 2.642， 95% confidence interval （CI） of 1.105-6.323］，combined administration： spleen aminopeptide （OR of 4.978， 95%CI of 1.200-20.655），and reason for combined administration： anti-infection （OR of 1.814， 95%CI of 1.071-3.075） were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%，and the severity was mainly mild or moderate. Generally，the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction，suggesting that FLK has good clinical safety.

Background Per- and polyfluoroalkyl substances (PFAS) are a class of persistent organic pollutants widely used in various products, leading to population exposure and long-term accumulation. At present, there is a lack of research on the relationships between pre-pregnancy PFAS and menstrual characteristics among women undergoing assisted reproductive technology (ART) in China. Objective To explore the relationships between pre-pregnancy PFAS exposure among women undergoing ART and menstrual characteristics prior to assisted reproductive treatment. Methods This study employed a cross-sectional research design, recruiting women undergoing ART treatment at the Reproductive Clinic of the International Peace Maternity & Child Health Hospital, School of Medicine, Shanghai Jiao Tong University, from 2017 to 2020 as study participants. Ultra-high-performance liquid chromatography-tandem mass spectrometry was used to detect 42 types of PFAS in pre-pregnancy serum samples. Questionnaires were administered to collect information on demographic characteristics, lifestyle habits, and menstrual characteristics (average menstrual cycle length, average menstrual period length, menstrual irregularities, and menstrual bleeding volume) of women undergoing ART. Multiple linear regression, binary logistic regression, and multinomial logistic regression analyses were performed to investigate the relationships between individual PFAS exposure before pregnancy and menstrual characteristics among ART women. Additionally, weighted quantile sum (WQS) model was applied to analyze the association between PFAS mixtures and menstrual characteristics. Results In the pre-pregnancy serum samples of the study population, 15 PFAS were detected in more than 60% of the samples, including perfluoroheptanoic acid (PFHpA), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), perfluoroundecanoic acid (PFUnDA), perfluorododecanoic acid (PFDoDA), perfluorobutanesulfonic acid (PFBS), perfluorohexanesulfonic acid (PFHxS), perfluoroheptanesulfonic acid (PFHpS), perfluorooctanesulfonic acid (PFOS), 6:2 chlorinated polyfluorinated ether sulfonate (6:2 Cl-PFESA), 8:2 chlorinated polyfluorinated ether sulfonate (8:2 Cl-PFESA), perfluoro-2-propoxypropanoic acid (HFPO-DA), perfluoro-2-methoxyacetic acid (PFMOAA), and perfluoro-(3,5,7,9,11-pentaoxadodecanoic) acid (PFO5DoDA). Among them, PFOA had the highest median concentration of 9.160 ng·mL⁻¹. The single PFAS exposure analysis revealed a positive correlation between PFAS and irregular menstrual cycles. Specifically, for every natural-log unit (e) increase in PFOA, PFBS, or PFHxS level, the incidence of irregular menstrual cycles increased by 57%, 42%, or 39%, respectively. Most PFAS were positively correlated with the average number of menstrual cycle days, such as PFHpA (b=1.08, 95%CI: 0.11, 2.05), PFOA (b=1.69, 95%CI: 0.39, 3.00), PFBS (b=1.23, 95%CI: 0.25, 2.22), PFHxS (b=1.47, 95%CI: 0.61, 2.32), PFHpS (b=1.48, 95%CI: 0.35, 2.61), and 6:2 Cl-PFESA (b=0.90, 95%CI: 0.08, 1.72). Furthermore, levels of PFHpA (OR=1.39, 95%CI: 1.06, 1.82), PFOA (OR=1.58, 95%CI: 1.09, 2.30), PFBS (OR=1.37, 95%CI: 1.04, 1.80), PFHxS (OR=1.34, 95%CI: 1.05, 1.71), PFHpS (OR=1.53, 95%CI: 1.10, 2.14), and 6:2 Cl-PFESA (OR=1.34, 95%CI: 1.06, 1.70) were positively correlated with low menstrual blood volume, while PFOA (OR=0.40, 95%CI: 0.23, 0.71), PFHpS (OR=0.45, 95%CI: 0.29, 0.71), and HFPO-DA (OR=0.68, 95%CI: 0.48, 0.97) were negatively correlated with high menstrual blood volume. The mixed exposure model showed that PFAS mixtures were positively correlated with the average number of menstrual cycle days (b=1.60, 95%CI: 0.49, 2.71), irregular menstrual cycles (OR=1.77, 95%CI: 1.19, 2.63), and low menstrual blood volume (OR=1.59, 95%CI: 1.08, 2.35), but negatively correlated with high menstrual blood volume (OR=0.40, 95%CI: 0.22, 0.73). Conclusion Women undergoing ART in Shanghai are widely exposed to PFAS prior to conception. Exposure to PFAS before pregnancy may be related to menstrual characteristics among women seeking ART before undergoing fertility treatments, but additional data from larger populations are required to validate the findings of this study.

Gender differences are reflected in specific changes in the fluctuation amplitude of certain parameters (such as PI), and the fluctuations of indicators like T-Cobb, T-LEV, and T-Apex are closely related to the natural aging process of the spine.

Denosumab, a human monoclonal antibody, is used for the prevention of malignant tumor-related bone events and the treatment of osteoporosis with high fracture risk. Since its approval in China in 2019, denosumab-related osteonecrosis of the jaw (DRONJ) has attracted increasing attention. DRONJ, similar to bisphosphonate-related osteonecrosis of the jaw, often occurs after tooth extraction and manifests as exposed bone necrosis, purulent discharge, facial swelling and pain, severely impacting patients′ quality of life. However, the perioperative management strategies for DRONJ differ from those for bisphosphonate-related osteonecrosis of the jaw. This article summarizes the perioperative management strategies for high-risk DRONJ patients from aspects such as oral hygiene care, antibiotic use, drug discontinuation during the perioperative period, and surgical strategy selection, aiming to provide guidance for oral surgeons in managing tooth extraction in denosumab-treated patients.

Objective To observe the value of clinical and CT radiomics features for predicting microsatellite instability-high(MSI-H)status of gastric cancer.Methods Totally 150 gastric cancer patients including 30 cases of MSI-H positive and 120 cases of MSI-H negative were enrolled and divided into training set(n=105)or validation set(n=45)at the ratio of 7∶3.Based on abdominal vein phase enhanced CT images,lesions radiomics features were extracted and screened,and radiomics scores(Radscore)was calculated.Clinical data and Radscores were compared between MSI-H positive and negative patients in training set and validation set.Based on clinical factors and Radscores being significant different between MSI-H positive and negative ones,clinical model,CT radiomics model and clinical-CT radiomics combination model were constructed,and their predictive value for MSI-H status of gastric cancer were observed.Results Significant differences of tumor location and Radscore were found between MSI-H positive and negative patients in both training and validation sets(all P＜0.05).The area under the curve(AUC)of clinical model,CT radiomics model and combination model for evaluating MSI-H status of gastric cancer in training set was 0.760,0.799 and 0.864,respectively,of that in validation set was 0.735,0.812 and 0.849,respectively.AUC of clinical-CT radiomics combination model was greater than that of the other 2 single models(all P＜0.05).Conclusion Clinical-CT radiomics combination model based on tumor location and Radscore could effectively predict MSI-H status of gastric cancer.

The blood oxygen was changed from 97.00%(5.00%) to 97.50%(3.00%), showing no significant difference before and after operation ( F=2.25, P>0.05). (3) Results of exercise and sleep monitoring. From preoperation to the third day after surgery, the number of steps fo 50 pati-ents was changed from 3 043(1 224) to 1 473(767), sleep duration was changed from(8.2±1.1)hours to(7.3±0.8)hours, sleep score was changed from 80±10 to 78±5,showing significant differences in above indicators before and after operation ( F=716.46, 29.02, 47.32, P<0.05).(4) Results of body composition monitoring. The body weight of 50 patients was changed from (63±8)kg to(61±8)kg before and after operation, body fat rate was changed from 24%±8% to 22%±9%, muscle mass was changed from 43 (12)kg to 41(17)kg, body mass index was changed from (23.0±2.6)kg/m 2 to(22.1±2.5)kg/m 2, showing significant differences in above indicators before and after operation ( t=8.19, 3.00, Z=-2.78, t=7.34, P<0.05), while there was no significant difference in basal metabolic indicators from (1 390±134)kcal to (1 379±139)kcal before and after operation ( t=1.02, P>0.05). Conclusion:The multi-dimensional digital monitoring platform for preoperative period can accurately monitor the perioperative stress level and evaluate the postoperative recovery of gastric cancer patients, which can present the visual results.

Runt-related transcription factor(RUNX1)is a transcription factor closely involved in hematopoiesis.RUNX1 gene mutation plays an essential pathogenic role in the initiation and development of hematological tumors,especially in acute myeloid leukemia.Recent studies have shown that RUNX1 is also involved in the regulation of bone development and the pathological progression of bone-related diseases.RUNX1 promotes the differentiation of mesenchymal stem cells into chondrocytes and osteoblasts and modulates the maturation and extracellular matrix formation of chondrocytes.The expression of RUNX1 in mesenchymal stem cells,chondrocytes,and osteoblasts is of great significance for maintaining normal bone development and the mass and quality of bones.RUNX1 also inhibits the differentiation and bone resorptive activities of osteoclasts,which may be influenced by sexual dimorphism.In addition,RUNX1 deficiency contributes to the pathogenesis of osteoarthritis,delayed fracture healing,and osteoporosis,which was revealed by the RUNX1 conditional knockout modeling in mice.However,the roles of RUNX1 in regulating the hypertrophic differentiation of chondrocytes,the sexual dimorphism of activities of osteoclasts,as well as bone loss in diabetes mellitus,senescence,infection,chronic inflammation,etc,are still not fully understood.This review provides a systematic summary of the research progress concerning RUNX1 in the field of bone biology,offering new ideas for using RUNX1 as a potential target for bone related diseases,especially osteoarthritis,delayed fracture healing,and osteoporosis.

OBJECTIVES: To evaluate the performance of different multi-modality fusion models for predicting radiation-induced oral mucositis (RIOM) following radiotherapy in patients with nasopharyngeal carcinoma (NPC). METHODS: We retrospectively collected the data from 198 patients with locally advanced NPC who experienced RIOM following radiotherapy at the Affiliated Tumor Hospital of Guangzhou Medical University from September, 2022 to February, 2023. Based on oral radiation dose-volume parameters and clinical features of NPC, basic classification models were developed using different combinations of feature selection algorithms and classifiers and integrated using a multi-criterion decision-making (MCDM)-based classifier fusion (MCF) strategy and its variant, the H-MCF model. The basic classification models, MCF model, the H-MCF model with a single modality or multiple modalities and other ensemble classifiers were compared for performances for predicting RIOM by assessing the area under the ROC curve (AUC), accuracy, sensitivity, and specificity. RESULTS: The H-MCF model, which integrated multi-modality features, achieved the highest accuracy for predicting severe RIOM with an AUC of 0.883, accuracy of 0.850, sensitivity of 0.933, and specificity of 0.800. CONCLUSIONS Compared with each of the individual classifiers, the multimodal multi-classifier fusion algorithm combining clinical and dosimetric modalities demonstrates superior performance in predicting the incidence of severe RIOM in NPC patients following radiotherapy.
