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 discuss the application of ankle pump exercise with colorful ring counting command in improving the blood hypercoagulable state in patients after hepatic arterial infusion chemotherapy(HAIC).Methods A total of 105 patients,who received HAIC at the Interventional Department of a certain Grade A general hospital in Fujian Province of China from January to December of 2023,were collected.The 53 patients who received treatment from January to June of 2023 were used as the control group,and the other 52 patients who received treatment from July to December of 2023 were used as the study group.The postoperative routine nursing and ankle pump exercise was employed for the patients of the control group,while ankle pump exercise with colorful ring counting command on the basis of postoperative routine nursing was carried out for the patients of the study group.The resting status of popliteal vein,the maximum and average systolic blood flow velocity at the end of exercise,the changes in coagulation index,the incidence of deep vein thrombosis,and the compliance of ankle pump were compared between the two groups.Results There were no statistically significant differences in the resting popliteal vein blood flow velocity and incidence of deep vein thrombosis between the two groups(P＞0.05).The maximum and average popliteal vein blood flow velocity at the end of exercise in the study group were higher than those in the control group.The levels of PT,APTT,FBG,TT and D-dimer(D-D)at 72 hours after HAIC were lower than those in the control group(all P＜0.05),and the compliance of ankle pump exercise in the study group was better than that in the control group(P＜0.05).Conclusion Ankle pump exercise with colorful ring counting command can accelerate lower limb blood flow velocity,improve the blood hypercoagulable state,and improve compliance with ankle pump exercise in patients after receiving HAIC.

Objective:To explore the effects and mechanisms of Shen-su-yin (SSY) on acute lung injury (ALI) in rats based on untargeted Metabolomics, network pharmacology, and experimental verification.Methods:Untargeted Metabolomics was performed to detect the ingredients of SSY by using ultra-high performance liquid chromatography-Q-exactive orbitrap mass spectrum, and the active ingredients were screened from the detected ingredients. Common targets of the active ingredient targets and ALI targets were utilized to screen hub targets to perform gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. Then, key hub targets were selected from the hub targets, and the active ingredients-hub targets network was built to screen core ingredients. Subsequently, molecular docking was performed between the key hub targets and the core ingredients. 48 rats were randomly and equally divided into 4 groups by using a random number table: normal control group, lipopolysaccharide-induced ALI group, ALI+SSY group, and ALI+dexamethasone group. 24 hours after lipopolysaccharide induction, the levels of respiratory rate, blood lactate, lung wet/dry weight ratio, ALI score, inflammatory factors of bronchoalveolar lavage fluid, and oxidative stress mediators of lung tissue in each group were evaluated, and the expression of phosphatidylinositol 3-kinase (PI3K)-protein kinase B (AKT)-glycogen synthase kinase (GSK) 3β-nuclear factor erythroid 2-related factor 2 (Nrf2)/nuclear factor (NF)-κB signaling pathway was also detected by using Western blot. Finally, one-way analysis of variance, Welch test, or Kruskal-Wallis H test was used to compare data differences among groups. Results:A total of 415 ingredients were detected from the SSY. 66 of the detected ingredients were identified as active ingredients, and 10 of them were selected as core ingredients. The number of common targets, hub targets, and key hub targets was 337, 50, and 10, respectively. Total of 285 biological processes, 32 cellular components, and 51 molecular functions were enriched though GO analysis, and 148 cell signaling pathways such as pathways in cancer and PI3K-AKT signaling pathway were enriched though KEGG analysis. Molecular docking studies revealed that all binding energies between the 10 key hub targets and the 10 core ingredients were less than -5 kcal/mol. Compared with the ALI group, the levels of the respiratory rate, blood lactate, and lung wet/dry weight ratio in ALI+SSY group were significantly decreased (all P<0.01), and the level of ALI score showed a downward trend, but the difference was not statistically significant ( P>0.05). In addition, the levels of interleukin-6, interleukin-1β, and tumor necrosis factor-α in bronchoalveolar lavage fluid and the levels of malondialdehyde, protein carbonyl, and 8-hydroxy-2-deoxyguanosine in lung tissue of rats in ALI+SSY group were significantly decreased in comparison with those in ALI group (all P<0.01). Moreover, compared with the ALI group, the phosphorylation levels of PI3K p85α, AKT1, and GSK3β and the expression level of Nrf2 in lung tissue of ALI+SSY group were significantly up-regulated (PI3K p85α phosphorylation and AKT1 phosphorylation, P<0.01; GSK3β phosphorylation and Nrf2, P<0.05), while the phosphorylation level of NF-κB p65 was significantly down-regulated ( P<0.01). Conclusions:Active ingredients detected from SSY via untargeted Metabolomics can inhibit oxidative stress and inflammation in ALI rats by regulating the PI3K-AKT-GSK3β-Nrf2/NF-κB signaling pathway, thereby alleviating lung lesions.

Objective:To investigate the clinical efficacy of propofol on blood pressure (BP) and heart rate (HR) in hypertensive patients with hyperacute uncomplicated type B aortic dissection (HU-TBAD).Methods:This study was a single-center, double-blind, randomized controlled trial. Totally 96 consecutive hypertensive patients with HU-TBAD admitted to the Department of Emergency in our hospital from July 2020 to March 2023 were enrolled and randomly divided into control and treatment groups ( n=48/group) by envelope method. All patients were treated with nicardipine, remifentanil, esmolol, and basic treatments. Besides, patients in the treatment group were injected with 0.5 mg/kg propofol, followed by 1.0 mg/(kg·h) with continuous micro-pump intravenous infusion; the RASS score was evaluated every 15 minutes to adjust the dosage of propofol to maintain the RASS score at -2-0 points, while the control group was given an equal volume of normal saline. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and HR were analyzed at different time points (TPs). Related indexes between the two groups were compared at 0 (T 0 min) and 60 (T 60 min) minutes. Standard-reaching rate of related indexes, levels of mean nicardipine dose (mND) and urine volume, and adverse effect rates (AERs) were also compared between the two groups. All patients were admitted to the cardiovascular surgical ward to receive proper management and follow-up for 21 d after discharge from the Department of Emergency. Mann-Whitney U test, t-test, χ2 test, or Fisher's test were used to compare the data between the two groups, while the data of two groups at different TPs were compared by using repetitive measurement deviation analysis. Results:No significant differences were observed in general clinical data between the two groups (all P>0.05). There were significant differences in SBP, DBP, and HR levels in different TPs, groups, and interaction of Time and Group (Time×Group) (all P<0.05). For comparison of related indexes at T 0 min and T 60 min, there were statistical differences in oxygenation index levels at different TPs ( P<0.01), but not in different groups and Time×Group (all P>0.05); significant differences in levels of partial pressure of carbon dioxide, respiratory rate, and lactate were observed in different TPs and Time×Group (all P<0.01), but not observed in different groups (all P>0.05). There were significant differences in NRS score in different TPs, groups, and Time×Group (all P<0.05), while not in cardiac troponin I levels in different TPs, groups, and Time×Group (all P>0.05). Compared with the control group, the standard-reaching rate of SBP, DBP, HR, sedation, and analgesia as well as the level of RASS score reduction in the treatment group were significantly increased [54.17% vs. 77.08%, 56.25% vs. 81.25%, 50.00% vs. 72.92%, 47.92% vs. 72.92%, 43.75% vs. 83.33%, 1.00 (0, 2.00) vs. 2.00 (1.00, 3.00), respectively, all P<0.05], while the level of mND was significantly decreased [μg·kg -1·min -1, 2.50 (2.00, 2.50) vs. 2.00 (1.50, 2.50), P<0.01]; there were no statistical differences in both urine volume levels and AERs between the two groups (all P>0.05). Following up for 21 d, the rate of aortic dissection deterioration and ICU admission was significantly lower in the treatment group than in the control group (19.57% vs. 4.26%, 23.91% vs.6.38%, respectively, all P<0.05). Conclusions:Propofol enhances the analgesic effect of remifentanil, synergistically reduces SBP, DBP, and HR, and improves clinical prognosis in hypertensive patients with HU-TBAD.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Collagen contains abundant cell binding motifs, which are conducive to adhesion, migration, and differentiation, maintain cell vitality and promote cell proliferation. However, pure collagen hydrogel has some shortcomings such as poor mechanical properties, poor thermal stability and fast degradation. Numerous studies have shown that the properties of collagen can be improved by combining it with natural polysaccharides such as alginate, chitosan, hyaluronic acid and cellulose. In this paper, the research status and biological application fields of four kinds of composite hydrogels, including collagen-alginate composite hydrogels, collagen-chitosan hydrogels, collagen-hyaluronic acid hydrogels and collagen-cellulose hydrogels, were summarized. The common preparation methods of four kinds of composite hydrogels were introduced, and the future development direction of collagen-based composite hydrogels was prospected.

Objective:To investigate the effect of specnuezhenide on high glucose-induced human retinal microvascular endothelial cells (hRMECs) injury and its mechanism.Methods:The hRMECs were divided into a normal control group cultured in a culture medium containing 5.5 mmol/L glucose, a hypertonic group cultured in a culture medium containing 5.5 mmol/L glucose + 24.5 mmol/L mannitol, a high glucose group cultured in a culture medium containing 30 mmol/L glucose, as well as high glucose+ low-, medium-, and high-dose specnuezhenide groups cultured in culture media containing 30 mmol/L glucose + 25, 50, 100 μmol/L specnuezhenide for 24 hours, respectively.In addition, hRMECs were divided into a high glucose+ small interfering RNA-negative control (si-NC) group cultured in a culture medium containing 30 mmol/L glucose, a high glucose+ si-forkhead box O4 (FOXO4) group cultured in a culture medium containing 30 mmol/L glucose, a high glucose+ specnuezhenide+ pcDNA group cultured in a culture medium containing 100 μmol/L specnuezhenide + 30 mmol/L glucose, and a high glucose+ specnuezhenide+ pcDNA-FOXO4 group cultured in a culture medium containing 100 μmol/L specnuezhenide+ 30 mmol/L glucose for 24 hours after transfection by corresponding reagents.Cell apoptosis was detected by flow cytometry.The malondialdehyde (MDA) concentration and superoxide dismutase (SOD) activity in cells were detected by the thiobarbituric acid method and xanthine oxidase method, respectively.The concentrations of interleukin (IL)-1β and tumor necrosis factor (TNF)-α in the cell culture supernatant were detected by enzyme linked immunosorbent assay.The relative expression level of FOXO4 protein in cells was determined by Western blot.Results:The apoptosis rates of normal control group, hypertonic group, high glucose group, high glucose+ low-, medium- and high-dose specnuezhenide groups were (7.32±0.72)%, (7.44±0.70)%, (23.96±1.32)%, (19.84±1.09)%, (14.13±0.85)% and (9.84±0.70)%, respectively.There were significant differences in cell apoptosis rate, MDA concentration, SOD activity, the concentration of IL-1β, the concentration of TNF-α, and the relative expression level of FOXO4 protein among the six groups ( F=498.545, 1 186.693, 516.629, 654.247, 638.238, 472.655; all at P<0.001). Compared with high glucose group, the apoptosis rate, MDA concentration, IL-1β and TNF-α concentration, FOXO4 protein expression level were significantly decreased in high glucose+ low-, medium- and high-dose specnuezhenide groups, and SOD activity was significantly increased in a dose-dependent manner.Compared with high glucose+ si-NC group, the expression level of FOXO4 protein, cell apoptosis rate, MDA concentration, IL-1β and TNF-α mass concentrations were decreased in high glucose + si-FOXO4 group, while the SOD activity was increased.Compared with high glucose+ specnuezhenide+ pcDNA group, the apoptosis rate, MDA concentration, IL-1β and TNF-α concentrations, FOXO4 protein expression level of hRMECs in high glucose+ specnuezhenide+ pcDNA-FOXO4 group were significantly increased, and SOD activity was significantly decreased (all at P<0.05). Conclusions:Specnuezhenide can protect hRMECs from high glucose-induced apoptosis, oxidative stress and inflammatory response by down-regulating FOXO4.

Primary ciliary dyskinesia (PCD) is a highly heterogeneous recessive inherited disorder. FAP54, the homolog of CFAP54 in Chlamydomonas reinhardtii, was previously demonstrated as the C1d projection of the central microtubule apparatus of flagella. A Cfap54 knockout mouse model was then reported to have PCD-relevant phenotypes. Through whole-exome sequencing, compound heterozygous variants c.2649_2657delinC (p. E883Dfs*47) and c.7312_7313insCGCAGGCTGAATTCTTGG (p. T2438delinsTQAEFLA) in a new suspected PCD-relevant gene, CFAP54, were identified in an individual with PCD. Two missense variants, c.4112A>C (p. E1371A) and c.6559C>T (p. P2187S), in CFAP54 were detected in another unrelated patient. In this study, a minigene assay was conducted on the frameshift mutation showing a reduction in mRNA expression. In addition, a CFAP54 in-frame variant knock-in mouse model was established, which recapitulated the typical symptoms of PCD, including hydrocephalus, infertility, and mucus accumulation in nasal sinuses. Correspondingly, two missense variants were deleterious, with a dramatic reduction in mRNA abundance from bronchial tissue and sperm. The identification of PCD-causing variants of CFAP54 in two unrelated patients with PCD for the first time provides strong supportive evidence that CFAP54 is a new PCD-causing gene. This study further helps expand the disease-associated gene spectrum and improve genetic testing for PCD diagnosis in the future.
