ObjectiveTo observe the clinical efficacy of Gandou Fumu Granules （GDFMG） combined with sodium dimercaptosulphonate （DMPS） on liver fibrosis in Wilson disease （WD） patients with the syndrome of phlegm and blood stasis， evaluate its effect on cuproptosis-related indicators， and explore the possible mechanisms of cuproptosis in WD-related liver fibrosis. MethodsSixty WD patients diagnosed with the syndrome of phlegm and blood stasis between January 2023 and December 2023 were randomly divided into a control group and an observation group， with 30 patients in each group. The control group received the copper chelator DMPS for the first 6 days， followed by calcium gluconate injection for the next 2 days， completing an 8-day treatment cycle. The observation group received GDFMG in addition to the treatment regimen of the control group， with both groups treated for 21 cycles. A Beckman fully automated biochemical analyzer was used to detect levels of type Ⅳ collagen （CⅣ）， hyaluronic acid （HA）， laminin （LN）， N-terminal propeptide of type Ⅲ procollagen （PⅢ-NP）， and serum copper （SCu） before and after treatment in both groups. Enzyme-linked immunosorbent assay （ELISA） was used to measure levels of ferredoxin 1 （FDX1）， lipoic acid synthetase （LIAS）， and dihydrolipoamide S-acetyltransferase （DLAT）. Atomic absorption spectroscopy measured 24-hour urine copper levels before treatment and after the 7， 14， and 21 treatment cycles in both groups. An Fibro Touch （FT） non-invasive liver fibrosis diagnostic device was used to measure liver stiffness （LSM） in both groups before and after treatment. Traditional Chinese medicine syndrome score （TCMSS） was evaluated at the same intervals. Clinical efficacy， adverse events， and safety indicators were also compared. ResultsAfter treatment， levels of CⅣ， HA， LN， and PⅢNP significantly decreased in both groups compared to pre-treatment levels （P<0.01）. The observation group showed a more pronounced reduction compared to the control group （P<0.05）. There were no statistically significant differences in SCu levels in both groups before and after treatment. After treatment， levels of FDX1，LIAS and DLAT significantly increased in both groups（P<0.01）. The observation group showed more notable improvements in these indicators than the control group （P<0.05）. After the 7， 14， 21 treatment cycles， 24-hour urine copper levels significantly increased in both groups compared to pre-treatment levels （P<0.01）. The observation group had a greater increase in 24-hour urine copper levels than the control group after treatment （P<0.05，P<0.01）， and although 24-hour urine copper levels increased after 7 cycles， a gradual decline was observed in subsequent cycles. After treatment， LSM levels significantly decreased in both groups compared to pre-treatment levels （P<0.01）， with the observation group showing a greater reduction than the control group （P<0.05）. Clinical efficacy was significantly better in the observation group than the control group （P<0.05）. No significant differences in the incidence of adverse events or safety indicators were observed between the two groups after treatment. ConclusionGDFMG combined with DMPS can reduce LSM in WD patients with liver fibrosis and the syndrome of phlegm and blood stasis， inhibit cuproptosis， and improve clinical efficacy.

Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics. There is an urgent need for a precise and adaptable restoration strategy that is more suitable for older individuals. The proposal of a new concept of functional tooth loss updates the minimal restoration standards for elderly patients and establishes the theory of age-friendly functional restoration. Based on the restoration strategy of functional tooth loss, this paper proposes a new concept termed "age-friendly functional restoration of the stomatognathic system", which integrates treatment considerations including endodontics, periodontology, mucosa, muscles, temporomandibular joint, and systemic health. Efforts should be made in four areas as follows. Firstly, the "assessment of accessible function" should be enhanced by considering the interrelationship between stomatognathic and systemic health. Secondly, the "evaluation of appropriate function" is supposed to be optimised in view of subjective needs and objective evaluation of the stomatognathic system. Moreover, the "formulation of treatment plans" needs to be accomplished with the aid of assistive technologies, such as artificial intelligence, to accurately exert appropriate functional restoration. Lastly, the "management and maintenance of health" is likely to be strengthened through follow-ups, propaganda and education, and preventive healthcare, so as to improve quality of life and ultimately achieve healthy ageing among older individuals.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective:To investigate the effect of cytoskeleton-associated protein 4 (CKAP4) gene knockout on maxillary expansion osteogenesis and its regulatory mechanism on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSC).Methods:Nineteen wild type (WT) and nineteen CKAP4 gene knockout (Ckap4 -/-) mice aged 6-8 weeks were selected to establish a mouse model of rapid maxillary expansion. Samples were taken on the 7th and 14th day after the operation. Micro-CT and HE staining were used to evaluate bone regeneration. Tissue proteins in the modeled area were collected, and Western blotting analysis (WB) was used to detect the protein expression levels of alkaline phosphatase (ALP), Runt-related transcription factor 2 (RUNX2), and osteocalcin (OCN). BMSC were isolated from WT and Ckap4 -/- mice. The expression of surface markers CD29, Sca-1, CD44, CD45, CD34, and CD11b was detected by flow cytometry, and cell proliferation ability was detected by 5-ethynyl-2'-deoxyuridine (EdU). After 7 days of osteogenic induction, real-time fluorescence quantitative PCR (RT-qPCR) and WB were used to detect the expression levels of RUXN2, ALP, OCN, protein kinase B (AKT), and phosphorylated protein kinase B (p-AKT). After 21 days, alizarin red staining and cetyl pyridine chloride quantification were used to detect the differences in mineralized nodule formation in each group. In CKAP4 gene knockout BMSC, the small-molecule AKT agonist sc79 (4 μg/ml) was added as the intervention group (Ckap4 -/- +sc79), and dimethyl sulfoxide (DMSO) treatment was used as the control group (Ckap4 -/- +DMSO). After osteogenic induction, RT-qPCR, WB, and alizarin red staining were used to compare the osteogenic differentiation differences between the two groups of cells. Results:The micro-CT results showed that at 7 days and 14 days after surgery, the new bone volume in the Ckap4 -/- group [(0.070±0.010) and (0.146±0.019) mm 3] was significantly lower than that in the WT group [(0.094±0.006) and (0.196±0.013) mm 3] (both P<0.01). HE-stained histological sections showed that the area of new bone tissue in the Ckap4 -/- group at 7 days and 14 days after surgery [(0.101±0.008) and (0.158±0.010) mm 2] was also significantly lower than that in the WT group [(0.116±0.005) and (0.183±0.008) mm 2] (both P<0.05). WB was used to detect the tissue proteins in the maxillary modeling area of mice in the two groups 7 days after surgery. The results showed that the expression levels of ALP, RUNX2 and OCN in the Ckap4 -/- group were significantly lower than those in the WT group. BMSC from wild-type mice and CKAP4 knockout mice were both positively expressed for CD29, CD44, and Sca-1, and basically not expressed for CD45, CD34, and CD11b. EdU assay showed that there was no significant difference in the proliferation ability of cells in the two groups. After 21 days of osteogenic induction of BMSC, alizarin red staining results showed that the number of mineralized nodules in the Ckap4 -/- group was significantly less than that in the WT group. After adding sc79, the number of mineralized nodules increased significantly, which was consistent with the results of cetyl pyridine chloride quantification. After 7 days of osteogenic induction, It was found that the expression levels of ALP, RUNX2, and OCN in the CKAP4 -/-group (0.751±0.066, 0.484±0.040, 0.679±0.063) were significantly lower than those in the WT group (1.000±0.113, 1.000±0.081, 1.000±0.113) (all P<0.001). The results of WB were consistent with those of RT-qPCR. At the same time, the WB results showed that the level of p-AKT protein in the CKAP4 -/-group (0.518±0.114) was significantly lower than that in the WT group (1.000±0.234) ( P<0.05). After treatment with sc79 for 7 days of osteogenic induction, RT-qPCR was used to detect the gene expression levels of ALP, RUNX2, and OCN. The results showed that the expression levels in the CKAP4 -/-+sc79 group (2.755±0.353, 4.800±0.990, 2.524±0.137) were significantly higher than those in the CKAP4 -/-+DMSO group (1.000±0.078, 1.000±0.247, 1.000±0.175) (all P<0.001). Conclusions:CKAP4 knockout inhibits the osteogenic differentiation of BMSC by reducing the activity of the PI3K/AKT signaling pathway, thereby suppressing osteogenesis in maxillary expansion.

Objective:To investigate the effect of altitude on the risk of pre-eclampsia (PE).Methods:This cross-sectional study included 19 246 pregnant women who delivered in Gansu Provincial Hospital from January 2016 to December 2020. General clinical data, pregnancy outcomes and neonatal outcomes were collected. The diagnosis of PE was based on the disease diagnosis coding of medical record information system and the Chinese guidelines for the diagnosis and treatment of hypertensive disorders in pregnancy (2020). According to the altitude of residence, the subjects were divided into low altitude group (9 931 cases), middle altitude group (9 068 cases) and high altitude group (247 cases). Univariate and multivariate logistic regression analyses were used to evaluate the relationship between altitude and the risk of PE, after adjusting for confounding factors such as age, ethnicity, mode of conception, gestational diabetes mellitus, and hemoglobin level.Results:(1) Among the 19 246 pregnant women, 752 (3.91%, 752/19 246) were diagnosed with PE. The incidence of PE in the low altitude group, middle altitude group and high altitude group was 2.95% (293/9 931), 4.91% (445/9 068) and 5.67% (14/247), respectively. With the increase of living altitude, the incidence of PE increased significantly ( P<0.001). (2) The results of univariate logistic analysis showed that compared with the low altitude area, the risk of PE in pregnant women living in the middle altitude area and high altitude area increased by 70% ( OR=1.70, 95% CI: 1.46-1.97; P<0.001) and 98% ( OR=1.98, 95% CI: 1.14-3.43; P=0.016). (3) The results of multivariate logistic regression analysis showed that after fully adjusting for confounding factors, the risk of PE increased by 40% for every 500 meters of elevation ( OR=1.40, 95% CI: 1.25-1.57; P<0.001). Compared with those living in low altitude areas, the risk of PE in pregnant women living in middle altitude and high altitude areas increased by 72% ( OR=1.72, 95% CI: 1.47-2.00; P<0.001) and 100% ( OR=2.00, 95% CI: 1.07-3.74; P=0.030). Conclusion:In the high-altitude environment of Gansu Province, the risk of PE gradually increases with the increase of altitude.

Objective:To summarize the clinical characteristics and first aid measures of children with drowning，and to provide scientific basis for the treatment and prevention of drowning in children.Methods:The clinical data of drowning children admitted to the Children's Medical Center of the First Affiliated Hospital of Hunan Normal University（Hunan Provincial People's Hospital）from January 2011 to December 2021 were retrospectively summarized. Baseline characteristics，prehospital emergency care and prognosis of the included children were analyzed.According to the time span, drowning children were divided into two stages, the first stage (2011-2016) and the second stage (2017-2021). According to cerebral performance category assessment scale,drowning children with cardiac arrest were divided into two groups: a group with good neurological prognosis and a group with poor neurological prognosis. The baseline characteristics,pre-hospital emergency care, and prognosis of drowning children during different periods and with different prognosis were analyzed.Results:A total of 53 children were enrolled during the study period，with 24 cases in the first phase（2011-2016）and 29 cases in the second phase（2017-2021）.Boys accounted for 73.6%（39/53）of the cases, the age ranged from 1 month and 24 days to 14 years old，with 1-4 years old being the most common，accounting for 58.5%（31/53）, and the season in which drowning occurred was more common in the summer（39.6%, 21/53）.Six cases (11.3%) had significant neurological sequelae, and the mortality rate was 3.8%（2/53）.There was a decrease in the proportion of drowning with water control in the second stage compared to the first stage（37.5% vs. 13.79%, P=0.046）.Thirty-two（60.4%）children experienced on-site cardiopulmonary resuscitation(CPR) after drowning，with 24 cases in the group with good neurological prognosis and 8 cases in the group with poor neurological prognosis.Children in the poor neurological prognosis group required CPR for a long duration [10.00（1.50, 25.00）min]，had lower body temperature，Glasgow Coma Score，pH and higher blood glucose levels on admission（all P < 0.05）. Conclusion:Drowning is most common in preschool children，common in boys，and drowning prevention measures for young children deserve focused attention. Children found to be in cardiac arrest at the time of drowning have a long duration of drowning and CPR，which predicts a poor neurological prognosis，and timely and effective on-site CPR is the key to reducing the drowning rate.

Objective:To analyze the correlation between the use of antithrombotic drugs,results of ultrasound examination and the change characteristics of thromboelastogram in patients with atrial fibrillation.Methods:A total of 80 patients with atrial fibrillation who admitted to Wuhan Red Cross Hospital were selected from January 2021 to October 2022.According to with or without thrombosis in patients,they were divided into an observation group(with thrombosis,26 cases)and a control group(without thrombosis,64 cases).All patients were treated by using antithrombotic drugs.Both of two groups underwent ultrasound and thromboelastogram examinations before and after treatment.The difference of the examination results between the two groups were compared.The correlation analysis was adopted to analyze the correlation between each indicator and the curative effect of antithrombotic drugs in patients with atrial fibrillation.Results:There was no significant difference in examination indicators of echocardiogram between the two groups before treatment(P>0.05).After treatment,the left atrial ejection fraction and left ventricular ejection fraction of the observation group were significantly lower than those of the control group(t=5.325,5.285,P<0.05).The differences in the indicators of thromboelastogram between the two groups were not significant before treatment(t=1.325,1.425,P>0.05),respectively.After treatment,the response time(R value)[(5.0±1.6)min]and coagulation time(K value)[(2.4±0.6)min]of the observation group were significantly lower than(9.8±2.2)min and(5.7±1.8)min of the control group(t=5.326,5.564,P<0.05),and the differences were significant(t=5.362,5.564,P<0.05),respectively.The correlation analysis indicated that there were correlations between left atrial ejection fraction,left ventricular ejection fraction,R value,K value and the risks of anti-reducing thrombosis formation and the use effect of thrombotic drugs in patients with atrial fibrillation(r=0.552,0.546,0.546,0.532,P<0.05),respectively.Conclusion:The results of ultrasound examination and the change characteristics of thromboelastogram can guide patients with atrial fibrillation to use antithrombotic drugs,thereby increase the benefit rate of antithrombotic treatment,and improve the prognosis of patients.

This article introduces a high-throughput molecular screening chip： peptide arrays. As a kind of biochip， the peptide arrays are easy to synthesis， stable in probe chemistry， high-throughput in screening and highly specific compared with other biochips. To analyze the new high-throughput data， researchers have recently proposed a series of deep learning and bioinformatics methods to study the binding characteristics of peptide probes and target molecules. Those algorithms could be used to predict the binding affinity of protein targets against peptides. Moreover， peptide arrays could also play important roles in analyzing protein-protein interactions，screening novel drug peptides， disease diagnosis and general health assessment based on recent reports. The application of this new technology could provide novel insights into public health research.
