With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:To investigate the reference intervals of serum uric acid levels in normal-weight children and analyze the factors influencing these levels.Methods:In this cross-sectional study, clinical data were collected from 7 910 normal-weight children, aged 1 month to 15 years, who underwent health check-ups at the Children′s Hospital of Zhejiang University School of Medicine between August 2013 and August 2023. Data included sex, age, pubertal signs, blood pressure, and serum uric acid levels. The participants were categorized into 4 age groups: 1-<12 months, 1-<6 years, 6-<11 years, and 11-<16 years, and were further analyzed by sex. The P5 and P95 percentiles of uric acid values were defined as the lower and upper limits of the reference interval, respectively. Correlation analysis and partial correlation analysis were used to assess the relationship between uric acid and other variables such as age, body mass index Z value, and Tanner stage. Multivariate linear regression was used to compare uric acid levels across gender and age groups, respectively. Results:Among the 7 910 children, the distribution across age groups was as follows: 562 (317 boys) in 1-<12 months, 4 120 (2 366 boys) in 1-<6 years, 2 357 (1 432 boys) in 6-<11 years, and 871 (536 boys) in 11-<16 years, the uric acid levels in boys were significantly higher than those in girls ( P<0.05). Uric acid levels exhibited a positive correlation with age ( r=0.47 , 0.20, both P<0.001), and a weak positive correlation with BMI Z-scores(both r=0.11, P<0.001). Among participants aged 6-<11 years and 11-<16 years, uric acid levels in boys were positively correlated with Tanner stage ( r=0.10, 0.27, both P<0.05), but no significant correlation was observed in girls (all P>0.05). The uric acid levels were significantly higher in boys than in girls in the 1-<12 months, 1-<6 years and 11-<16 years age groups (all P<0.05), but no significant gender difference was found in the 6-<11 years groups ( P>0.05). Uric acid levels exhibited statistically significant variations among age groups ( P<0.001). The reference intervals of uric acid values were as follows in 1-<12 months age group, 157-335 μmol/L for boys and 160-315 μmol/L for girls; in 1-<6 years age group, 180-359 μmol/L for boys and 180-355 μmol/L for girls; in 6-<11 years group, 190-375 μmol/L; in 11-<16 years age group, 237-480 μmol/L for boys and 218-410 μmol/L for girls. Conclusions:Reference intervals for uric acid varying significantly across different pediatric age groups. Sex, and pubertal development status are closely related to uric acid levels.

Objective:To construct a stable oral squamous cell carinoma(OSCC)cell line overexpressing miR-181a-5p,and to ob-serve the effects of miR-181a-5p on the biological behavior of the cells.Methods:miR-181a-5p lentivirus and the control virus vec-tor were respectively constructed and respectively transfected into OSCC CAL-27 cells.The stablely transfected cells(OE)and con-trol cells(NC)were screened out by purinomycin.The fluorescence of the cells was observed by laser confocal microscopy.The ex-pression of miR-181a-5p and Bcl-2 was detected by qRT-PCR and the expression of target protein Bcl-2 was detected by Western blot.The invasion,migration and proliferation ability of the cells were detected by cell scratch,Transwell assay and clonal formation assay.qRT-PCR was used to detect the expression of the related genes of cell invasion and migration.Results:It was found that the expression level of miR-181a-5p in OE cells was significantly higher than that in NC and untransfected control cells(P＜0.01).The expression of Bcl-2 in OE cells was significantly decreased.The invasion,migration and proliferation of OE cells were decreased.In ad-dition,the expression levels of MMP2,MMP9,Vimentin and Ki67 in OE cells were decreased,while E-cadherin was increased(P＜0.01).Conclusion:Overexpression of miR-181a-5p can significantly inhibit the proliferation,invasion and migration OSCC cells.

Objective:To investigate the diagnostic value of high-resolution magnetic resonance black blood technology imaging (MRBTI) and CT angiography (CTA) in detecting carotid plaque in predicting stroke.Methods:A prospective study was conducted on 135 patients with carotid artery disease diagnosed and treated in Handan Central Hospital from January 2020 to June 2022, all patients underwent cervical MRBTI and CTA examinations. Digital subtraction angiography (DSA) was used as the gold standard to compare the diagnostic value of the two detection methods for carotid plaque properties. Patients were followed up for 2 years and divided into stroke and non-stroke according to the result of follower-up. Imaging indexes of the two groups were compared, and the predictive value of MRBTI combined with CTA for stroke was evaluated by receiver operation characteristic (ROC) curve.Results:The relevant data of 134 patients were included in statistical analysis. For severe carotid stenosis and ulcerative plaques, the accuracy of CTA examination was 85.11% and 84.91% separately, that of MRBTI examination was 91.49% and 92.45%, the combined examination was 95.74% and 96.23%, and the above three examination methods was not statistically significant ( P>0.05). The detection accuracy rates of CTA for mild, moderate carotid artery stenosis and smooth, irregular plaque, were 73.08%, 86.89%, 73.91% and 86.21%, those of MRBTI detection were 92.31%, 91.80%, 86.96% and 93.10%, and those of combined detection were 100.00%, 98.36%, 100.00% and 98.28%, the combined detection was higher than those of CTA and MRBTI alone ( P<0.05); there was no statistically significant difference in the level of tube wall area between the stroke patients and the non-stroke patients ( P>0.05), but the total vascular area and lumen area in stroke patients were significantly higher than those in non-stroke patients: (103.48 ± 22.48) mm 2 vs. (92.51 ± 16.26) mm 2, (46.18 ± 11.03) mm 2 vs. (41.32 ± 10.52) mm 2, and normal wall index was significantly lower: (0.54 ± 0.12) mm 2 vs. (0.61 ± 0.09) mm 2 ( P<0.05); ROC curve analysis showed that MRBTI combined with CTA had the best predictive efficacy for stroke, with area under the curve (AUC) value as high as 0.82, and its sensitivity (79.00%) was significantly higher than that predicted by MRBTI indexes (total vascular area, lumen area and normal wall index) (51.90%, 39.50%, 56.80%) or CTA (30.90%) alone, with statistically significant difference ( P<0.05). Conclusions:The combination of MRBTI and CTA can improve the diagnostic efficiency of carotid artery disease and the prediction efficiency of stroke, and can be used as an auxiliary examination means of DSA to provide a more reliable clinical basis for the assessment of plaque characteristics in patients with carotid artery disease and the prediction of stroke.
