BACKGROUND:Eucommia ulmoides has a certain osteogenic effect,which can promote the proliferation and differentiation of osteoblasts.However,it is unclear whether Eucommia ulmoides has effects on alveolar bone formation and Wnt/β-Catenin signaling pathway. OBJECTIVE:To investigate the mechanism by which Eucommia ulmoides promotes alveolar bone formation in ovariectomized rats based on the Wnt/β-Catenin signaling pathway. METHODS:Sixty female Sprague-Dawley rats were selected and randomly divided into five groups:blank control group,sham-operation group,model group,low-dose group Eucommia ulmoides group,and high-dose Eucommia ulmoides group,with twelve rats in each group.Osteoporosis animal models were constructed by bilateral oophorectomy in the model group and the low-dose and high-dose Eucommia ulmoides groups.The sham-operation group underwent the same method to remove adipose tissue of equal mass around the bilateral ovaries.Three months after surgery,the low-and high-dose Eucommia ulmoides groups were given 2.1 g/kg/d and 4.2 g/kg/d Eucommia ulmoides by gavage,respectively.The sham-operation group and model group were given the same amount of physiological saline by gavage.After 12 weeks of drug intervention,the changes in alveolar bone mass of rats in each group were observed through Micro-CT;hematoxylin-eosin staining was used to observe the pathological structural changes of alveolar bone in rats;enzyme linked immunosorbent assay was used to detect the expression levels of alkaline phosphatase and osteocalcin in the serum of rats;western blot was used to detect the expression levels of β-Catenin and Frizzled9 receptor proteins in the alveolar bone of rats;and real-time fluorescence quantitative PCR was used to detect the expression of osteocalcin,Runt-related transcription factor 2(Runx2),alkaline phosphatase,β-catenin,and frizzled9 mRNAs in alveolar bone tissues of rats. RESULTS AND CONCLUSION:Compared with the blank control group,bone volume fraction,trabecular number,trabecular thickness,and bone mineral density were reduced in the model group(P<0.05),and trabecular separation was elevated(P<0.05).Pathological observation showed that the arrangement of trabeculae was disordered and irregular,the trabeculae were thinned or broken,and the marrow cavity was enlarged in the model group,with a significant reduction in bone volume;the level of alkaline phosphatase in the serum was increased(P<0.05),and the level of osteocalcin was decreased(P<0.05);mRNA expression of alkaline phosphatase,osteocalcin,Runx2,β-catenin,and frizzled9 were decreased(P<0.05);protein expression of β-Catenin and Frizzled9 was decreased(P<0.05).Compared with the model group,the low-and high-dose Eucommia ulmoides groups showed an increase in bone volume fraction,trabecular number,trabecular thickness,and bone mineral density(P<0.05)and a decrease in trabecular separation(P<0.05).In the low-and high-dose Eucommia ulmoides groups,bone trabeculae were slightly aligned and thickened,with a significant increase in bone mass.Compared with the model group,the serum level of alkaline phosphatase was reduced(P<0.05)and the serum level of osteocalcin was elevated(P<0.05)in the low-and high-dose Eucommia ulmoides groups.Compared with the model group,the mRNA expression of alkaline phosphatase,osteocalcin,Runx2,β-catenin,and frizzled9 were increased in the low-and high-dose Eucommia ulmoides groups(P<0.05).Compared with the model group,the protein expression of Frizzled9 was increased in the low-dose Eucommia ulmoides group(P<0.05),while the protein expression of β-Catenin and Frizzled9 was increased in the high-dose Eucommia ulmoides group(P<0.05).Compared with the low-dose Eucommia ulmoides group,the high-dose Eucommia ulmoides group had a more significant improvement in the above indexes.To conclude,Eucommia ulmoides can effectively promote the alveolar bone formation,and its mechanism of action might be related to the activation of the Wnt/β-catenin signaling pathway.

Objective:
To explore the association between mediterranean diet (MD) patterns and dental caries among children and adolescents with neurodevelopmental disorders (NDD), so as to provide a basis for developing scientific anti caries strategies related to diet.
Methods:
From December 2021 to June 2024, a questionnaire survey, a three day 24 hour dietary review survey, oral health examination, physical development measurement and Childhood Autism Rating Scale (CARS) evaluation were conducted involving 147 children and adolescents aged 2-22 years with NDD from nine special education schools and rehabilitation institutions in Tianjin. Group comparisons were carried out using the Mann-Whitney U test, Chi-square test, or Fisher s exact probability method. The correlation between dietary quality and dental caries was analyzed by adopting multiple linear regression analysis and restricted cubic spline.
Results:
There were 46 children and adolescents (31.3%) in the non dental caries group and 101 children and adolescents (68.7%) in the dental caries group. The number of decayed missing and filled teeth (dmft) was 2.0 (4.0), and the MD score was 4.0 (2.0) points. There were 62 children and adolescents (42.2%) in the low MD scores group and 85 children and adolescents (57.8%) in the high MD scores group. There was no significant difference in MD scores between NDD children in the non dental caries group and those in the dental caries group [nondental caries group:4.0(2.0), dental caries group:4.0(2.0), Z= -0.14, P >0.05]. The MD scores and dmft exhibited increasing and then decreasing trend ( P total =0.02, P non lineary = 0.04 ). Children and adolescents with NDD in the MD high scores group had a lower number of dmft than those in the MD low scores group ( β= -2.00 , 95%CI =-3.39 to -0.62, P <0.05). However, in children and adolescents with NDD and CARS scores ≥30, the above association was insignificant ( β=-0.63, 95%CI=-0.29-0.15, P >0.05).
Conclusion
Children and adolescents with NDD who have dietary patterns similar to the Mediterranean diet, are found to have fewer dental caries, and this is observed among those with no or mild symptoms of autism spectrum disorder.

ObjectiveTo explore the potential mechanism of Erchen Decoction (二陈汤, ECD) in improving metabolic syndrome (MS) with phlegm syndrome. MethodsForty mice were randomly divided into a blank group of 10 mice and a modeling group of 30 mice. The MS model with phlegm syndrome was induced in the modeling group by high-fat diet. Thirty successfully modeled mice were randomly divided into a model group, a ECD group, and a metformin group, with 10 mice in each group. The ECD group was given 0.4 g/(kg·d) of ECD, while the metformin group was intervened with 11.1 g/(kg·d) of metformin solution, and the blank group and the model group were given 0.02 ml/(g·d) of sterilized drinking water, all by gavage, once daily for 4 weeks. Body weight, abdominal circumfe-rence, body length, Lee's index and food intake were recorded. Blood glucose and blood lipid levels including fasting blood glucose, triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were measured. ELISA was used to detect serum leptin levels, while HE staining was used to observe liver pathological changes. Western Blot and q-PCR were used to detect protein and mRNA expression of hypothalamic leptin receptor (LepR), pro melanocortin (POMC), and neuropeptide Y (NPY) in the hypothalamus. Immunofluorescence was used to detect fluorescence expression of POMC and NPY in the hypothalamic arcuate nucleus region. ResultsPathological results showed that the mice in the model group had numerous fat vacuoles in hepatocytes and significant liver fat deposition, while the ECD and metformin groups showed reduced fat vacuoles and less liver fat deposition. Compared to those in the blank group, the mice in the model group mice showed liver fat deposition, increased body weight, abdominal circumference, Lee's index and food intake; fasting blood glucose, TG, TC, LDL-C, and serum leptin levels were elevated, while HDL-C was decreased; the expression of LepR, POMC protein levels and their mRNA expression decreased, while the protein level and mRNA expression of NPY increased; the fluorescence expression of POMC in the arcuate nucleus was reduced, while NPY fluorescence expression increased (P<0.05 or P<0.01). Compared to the model group, the ECD group and metformin group showed significant improvements in the above indicators (P<0.05 or P<0.01). Compared to the ECD group, the metformin group showed a reduction in body weight and NPY fluorescence expression, and an increase in HDL-C levels (P<0.05 or P<0.01). ConclusionECD can downregulate serum leptin levels and improve glucose and lipid metabolism in the MS of phlegm syndrome. Its mechanism of action may be to reduce liver fat deposition and thereafter affect the expression of neuropeptides related to feeding activity in the hypothalamus.

To analyze the disease burden, temporal trends, and attributable risk factors of early-onset female breast cancer (EOBC) in China and globally from 1990 to 2021. Data on the absolute numbers and crude rates of incidence, mortality, and disability-adjusted life years (DALYs) for EOBC (diagnosis age < 50 years) in China and globally were extracted from the Global Burden of Disease (GBD) 2021 database. Attributable DALY proportions for five risk factors (smoking, alcohol use, physical inactivity, high red meat consumption, elevated fasting plasma glucose) and all combined risk factors were obtained. Joinpoint regression analysis was performed to assess temporal trends in age-standardized rates, quantified by annual percentage change (APC) and average annual percentage change (AAPC). From 1990 to 2021, age-standardized incidence rates of EOBC increased significantly in both China (AAPC=2.25%) and globally (AAPC=0.64%; pairwise comparison, China's age-standardized EOBC incidence is rising rapidly and approaching global levels, while mortality and DALY rates have increased over the past decade, underscoring persistent challenges in disease control. Future efforts should prioritize expanding the coverage of breast cancer screening programs, optimizing screening protocols, and enhancing public awareness of cancer prevention to mitigate the growing burden of EOBC in China.

Purpose:
The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations.
Methods:
This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits.
Results:
Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01).
Conclusion
Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.
