Objective: To understand the influence of the concept of movement education on the fundamental motor skills of preschool children aged 3-6, so as to provide a reference for improving the quality of preschool education and promoting the all round development of preschool children. Methods: From August 2022 to June 2023, 592 normally developing preschool children aged 3- 6 in a certain kindergarten in Qingdao were selected as the research objects by convenience sampling. They were randomly divided into the intervention group (physical education activities designed based on the concept of movement education) and the control group (original teaching plan). The intervention lasted for 24 weeks (twice a week, 40 minutes each time). Test of Gross Motor Development-2 (TGMD-2) was used to evaluate the children s gross motor skills, and repeated measures analysis of variance was used to analyze the data of the two groups before and after the intervention. Results: Except for running and kicking, the group main effects ( F group =18.78-104.77), time main effects( F time =243.23-3 003.19), and other interactive effects between group and time ( F group×time =14.01-322.91) were of statistical significances for gross motor, movement motor, manipulative motor and each sub indicator between intervention group and control group. Further simple effect analysis results showed that, before intervention, there were no statistically significant differences in the total scores of gross motor (48.95±10.65,45.87±10.98), movement motor ( 25.93± 7.31,23.46±7.32) and manipulative motor (23.15±4.40,22.40±4.69) between the intervention group and the control group ( F=3.69, 2.94, 1.90, P >0.05); and two goups were also found of no statistical significance in the each sub indicator of movement and manipulative motor ( F=0.01-3.58, P >0.05); after intervention, the total scores of gross motor, movement motor, and manipulative motor in the intervention group (75.92±9.48, 38.12±5.40, 37.80±4.92) were all better than those in the control group ( 59.52± 12.12, 30.71±7.47, 28.81±5.54) ( F =168.15, 97.58, 210.71), and the total indicators of both goups had better scores than those before the intervention ( F intervention = 3 498.90 , 1 438.27, 2 431.24; F control =545.58, 309.18, 283.29)(all P <0.01); after intervention, the intervention group had better scores in all sub indicators (except for running and kicking) than the control group ( F =43.57-297.71), and the each sub indicator of both goups had better scores than those before the intervention ( F intervention = 300.58-858.65; F control =12.28-135.64)(all P <0.01). Conclusion Physical education activities designed based on the concept of movement education could better promote the development of children s fundamental motor skills.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [¹⁵N₂]-cystine and [¹³C₅]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

Objective:To study the effect and mechanism of ganoderma lucidum polysaccharide peptide(GLPP)on renal anti oxidative stress and immune inflammation in diabetes nephropathy mice.Methods:The C57 male mice model of diabetes nephropathy was established by streptozotocin combined with high glucose and high-fat diet.Sixty diabetes nephropathy mice were divided into model group,losartan group,GLPP group(low,medium and high dose groups),GLPP high-dose+losartan group,with 10 mice in each group,10 mice fed with normal diet as the blank group.The losartan group was given 10 mg/kg losartan by gavage,and GLPP low,medium and high dose groups was given 50,100,and 200 mg/kg GLPP by gavage,while the GLPP high-dose+losartan group were given 200 mg/kg GLPP+10 mg/kg losartan by gavage.The blank group and model group were given physiological saline by gavage.After gastric lavage,observe the diet,water intake,renal pathology,structure,and apoptosis of renal tubular epithelial cells in mice,and analyze the levels of blood biochemical indicators,immune inflammation,oxidative stress indicators,and expression of apoptosis/cycle regulatory proteins in mice.Results:Compared with the blank group,the model group showed an increase in blood biochemical indicators such as Scr,BUN,TC,TG and GSP(P<0.05),as well as inflammation indicators such as level of IL-6 and TNF-α、MCP-1 were decreased(P<0.05),the oxidative stress indicator MDA was increased,T-AOC,GSH-PX,SOD were decreased(P<0.05),the apoptosis rate of renal tubular epithelial cells were increased(P<0.05),the expression levels of Bax,Caspase-3,P53,P21 were all increased,and the expression levels of Bcl-2 and Cyclin D1 were decreased(P<0.05).Compared with the model group,the losartan group,GLPP dose groups,GLPP high-dose+losartan group Scr,BUN,TC,TG,GSP,IL-6,TNF-α,MCP-1,MDA levels,apoptosis rate of renal tubular epithelial cells,Bax,Caspase-3,P53,P21 expression levels were all reduced,while T-AOC,SOD,GSH-PX levels,Bcl-2,and Cyclin D1 expression levels were all increased.Renal pathological changes were improved,and mitochondrial swelling was reduced.The GLPP high-dose+losartan group showed the most significant improvement(P<0.05).Conclusion:GLPP can reverse the renal injury in diabetes nephropathy mice,which may be related to the inhibition of apoptosis of renal tubular epithelial cells by alleviating renal oxidative stress and immune inflammatory damage.

Purpose This study aimed to explore the mucinous phenotype characteristics,key points of differenti-al diagnosis and prognosis of invasive non-mucinous adenocarcinoma(INMA)and invasive mucinous adenocarcinoma(IMA)under the WHO(2021)lung adenocarcinoma classification.Methods We retrospectively collected clinico-pathological data from 522 cases of lung adenocarcinoma,including 425 INMA(66 with mucin secretion,259 without mucin secretion)and 97 IMA.Immunohistochemical(IHC)staining using the EnVision method was performed on the mucin-secreting adenocarcinoma to assess expression of TTF-1,HNF4α,MUC1,MUC4,MUC5AC,MUC5B,and MUC6.Unsupervised clustering analysis was conducted to explore phenotypic subgroups.Results 522 patients with lung adenocarcinoma ranged from 32 to 83 years old(median:61).251 cases(48.1％)were male and 271 cases(51.9％)were female.Clustering analysis divided lung adenocarcinomas into two major groups:one characterized by TTF-1-/HNF4α+and gastric-type mucins MUC5AC+/MUC6+,predominantly IMA;the other,TTF-1+/HNF4α-/MUC4+,largely INMA.A three-marker IHC panel(TTF-1,HNF4α,MUC6)distinguished IMA from mucinous IN-MA with an area under the ROC curve(AUC)of 0.957(95％CI:0.928-0.986)and a Youden's index of 0.860.Further cluster analysis of INMA cases identified four phenotypic subgroups.Prognostic analysis demonstrated that pa-tients with advanced-stage mucin-secreting INMA had significantly shorter overall survival(OS)and progression-free survival(PFS)than those without mucin secretion(5-year OS:57.1％ vs 81.8％,P=0.004;3-year PFS:40.9％ vs 62.4％,P=0.004).No significant survival differences were noted among INMA subgroups stratified by varying mucin proportions.Multivariate analysis identified pathological stage,tumor necrosis,KRAS mutation,and TTF-1 negativity as independent adverse prognostic factors for both OS and PFS in mucinous INMA.Conclusion A three-marker im-munohistochemical panel of TTF-1,HNF4α,and MUC6 is recommended to distinguish IMA from mucinous INMA.Mucus component portends a worse prognosis in advanced INMA,with necrosis,KRAS mutations,and TTF-1 negativi-ty serving as independent adverse prognostic factors in mucinous INMA.

Objective To investigate the occurrence risk for common complications of internal jugular vein(IJV)and subclavian vein(SCV)catheterization,and provide reference for the prevention and treatment of common com-plications during clinical intravenous infusion therapy.Methods Data from China National Knowledge Infrastruc-ture(CNKI),Wanfang Database,VIP Database,Embase(via OVID),PubMed,Cochrane Library,CINAHL,Web of Science,and ScienceDirect were retrieved,with the search period from database establishment to August 3,2023.Prospective cohort and experimental studies on common complications in patients with IJV and SCV cathete-rization were collected.Meta-analysis on the extracted data was performed with RevMan 5.3 software.Results A total of 29 studies involving 14 096 patients were included in the analysis,including 6 355 patients with SCV cathe-terization(SCV group)and 7 741 patients with IJV catheterization(IJV group).Meta-analysis results showed that the occurrence risk for hemopneumothorax(OR=0.23,95％CI[0.14-0.37])and catheter tip ectopic(OR=0.16,95％CI[0.03-0.85])in SCV group was higher than that in IJV group,and the occurrence risk for central venous catheter-related deep venous thrombosis in IJV group was higher than that in SCV group(OR=2.35,95％CI[1.31-4.21]),with statistically significant differences(all P＜0.01).There were no statistical differences in the occurrence risk of vascular catheter-related bloodstream infection(CRBSI),catheter blockage,and catheter local he-matoma between the two groups(all P＞0.05),there was difference in the combined result of subgroup analysis re-garding catheter bacterial colonization.Conclusion Compared with IJV,patients in SCV group have a higher risk of developing hemopneumothorax and catheter tip ectopic,while patients with catheterization in IJV group have a high-er risk of deep veinous thrombosis.There are no significant differences in the occurrence risk for CRBSI,catheter blockage,and catheter local hematoma between two groups of patients.It is suggested that patient's own conditions and the accessibility of deep vein catheterization should be considered more when selecting the site of deep venous catheterization.

Objective:To explore the symptoms of Ménière′s disease patients and their impact on quality of life.Methods:A cross-sectional study was conducted, consecutively enrolling patients of Ménière′s disease who visited the Otolaryngology Clinic at the Eye & ENT Hospital of Fudan University from October 2014 to December 2022. The Chinese version of the Ménière′s Disease Outcomes Questionnaire (MDOQ) and a Ménière′s disease-specific symptom checklist were utilized for assessment. SPSS 25.0 software was employed to perform multiple linear regression analysis to determine the impact of Ménière′s disease symptoms on patients′ quality of life.Results:A total of 790 patients with a definitive diagnosis of Ménière′s disease who met the inclusion and exclusion criteria were analyzed. The cohort comprised 418 males and 372 females, with a mean age of (54.8±13.1) years and a diagnosis duration ranging from 0 to 72 months, with a median of 3 months. The total score of the Chinese MDOQ was 61.0±12.0. The symptomatic presentations of the enrolled patients included hearing changes, tinnitus, aural fullness, drop attacks, vertigo episodes, visual instability, dizziness, and headache. Multiple linear regression analysis revealed that age, tinnitus, aural fullness, frequency of drop attacks, visual instability, dizziness, and headache were significant factors affecting the quality of life in Ménière′s disease patients ( F=145.50, P<0.05). Conclusions:The quality of life in Ménière′s disease patients requires improvement. Attention to the specific symptoms of Ménière′s disease and their impact on patients′ quality of life, along with targeted symptom interventions based on these findings, will be a focal point in future disease management.

Objective To observe the characteristics of sublingual collaterals of patients with hypertension and the correlation between TCM syndromes and characteristics of sublingual collaterals based on image data.Methods Totally 303 patients with hypertension were selected from three hospitals in Anhui Province from October 2022 to April 2024,and were divided into liver fire hyperactivity syndrome,yin deficiency and yang hyperactivity syndrome,phlegm and blood stasis syndrome,and yin yang deficiency syndrome according to the syndromes.The patients'sublingual collateral images were captured using smartphones,and the AI open platform system for TCM tongue diagnosis was used to obtain the color,length,width,tortuous degree and concurrent manifestations of the sublingual collaterals,as well as the characteristic indexes,such as color HSV,Lab value,etc.of sublingual collaterals,using a combination of computer vision and manual interpretation,so as to analyze the correlation between the TCM syndromes and the characteristics of the sublingual collaterals.Results The color,length,width,tortuous degree and concurrent manifestations of sublingual collaterals in different syndrome types were statistically significant.The values of V,Lab-L,Lab-a and Lab-b in the phlegm and blood stasis syndrome were significantly lower than those in other syndrome types.The S value of yin-yang deficiency syndrome was significantly lower than that of other syndromes(P＜0.05).Correlation analysis showed that the color of sublingual collaterals was negatively correlated with the values of S,V,Lab-L,Lab-a and Lab-b of patients with different syndrome types(P＜0.05).The degree of stasis of sublingual collaterals in the phlegm and blood stasis syndrome was higher than that in other groups.Conclusion There are differences in color,length,width,tortuous degree and concurrent manifestations among the sublingual collaterals of patients with hypertension,and there is close correlation between the color of sublingual collaterals and its parameters.The objective index of sublingual collaterals is sensitive to hypertension,which is basically consistent with the theory and clinical conclusion of TCM,and can be used as the basis for syndrome differentiation and treatment.

Objective:To investigate the clinical characteristics and independent risk factors of severe disease in patients with anti-nuclear matrix protein (NXP) 2 antibody-positive juvenile dermatomyositis (JDM).Methods:A retrospective cohort study was conducted, including 219 anti-NXP2 antibody-positive JDM patients admitted to 23 children′s hospitals across China from July 2011 to July 2023. Patients were classified into severe and non-severe groups based on classification criteria for severe dermatomyositis. Demographic characteristics, clinical manifestations, and laboratory parameters were compared between the 2 groups using independent sample t-test, Mann-Whitney U test, or χ2 test. Univariate and multivariate Logistic regression analyses were performed to identify risk factors for severe disease. The receiver operating characteristic curve was employed to calculate optimal cut-off values. Results:Among the 219 patients, 108 were male and 111 were female, with an age at onset of 6.3 (3.5, 9.4) years. The severe group comprised 69 patients, and the non-severe group 150 patients. The severe group had significantly higher rates of fever, heliotrope rash, subcutaneous edema, periorbital edema, anti-Ro52 antibody positivity, as well as elevated levels of ferritin-to-albumin ratio (FAR), creatine kinase (CK), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) (all P<0.05). Multivariate analysis identified anti-Ro52 antibody positivity ( OR=13.26, 95% CI 1.37-128.29) and elevated FAR ( OR=1.90, 95% CI 1.09-2.31) as independent risk factors for severe anti-NXP2 antibody-positive JDM (both P<0.05). Receiver operating characteristic curve analysis revealed that a FAR cutoff value of 6.82 predicted severe disease with an area under the curve of 0.87 (95% CI 0.81-0.94, P<0.001), sensitivity of 0.85, and specificity of 0.70. All patients received glucocorticoid therapy, and the severe group received higher proportions of steroid pulse therapy, cyclophosphamide, mycophenolate mofetil, intravenous immunoglobulin, biologics, and adjuvant treatments compared to the non-severe group (all P<0.05). In terms of outcomes, 2 patients (2.9%) in the severe group died (due to neurological involvement and intestinal perforation, respectively), while the remaining patients achieved complete clinical response or remission. All patients in the non-severe group achieved remission. Conclusions:The primary clinical features of anti-NXP2 antibody-positive JDM included fever, heliotrope rash, subcutaneous edema, periorbital edema, anti-Ro52 antibody positivity, and elevated levels of CK, AST, LDH, and FAR. Furthermore, anti-Ro52 antibody positivity and a FAR>6.82 were identified as independent risk factors.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To investigate the clinical manifestations, pathological features, treatment methods and prognosis of primary renal synovial sarcoma (PRSS) in order to improve the clinical understanding and treatment level of the disease.Methods:The clinical data, pathological features, immunohistochemical indexes, SYT gene detection, treatment and follow-up results of 21 patients with PRSS reported in the First Affiliated Hospital of Soochow University from 2018 to 2023 were retrospectively analyzed. Kaplan-Meier method was used to calculate the relationship between age and cumulative survival rate. Results:The male to female ratio of PRSS patients was 16∶5, the ratio of left and right kidneys was 7∶14, the median age was 50 years old, the mean age was 44.5 years old, the median tumor length diameter was 9.7 cm, and the mean tumor length diameter was 6.7 cm. 57%(12/21) reported low back pain and 48%(10/21) reported gross hematuria. Immunohistochemical examination showed 100% positive for Vimentin(16/16), BCL-2(18/18) and TLE-1(10/10), 69%(9/13) and 85%(6/7) positive for CD99 and CD56, respectively. Genetic testing found SYT translocation signal in 92% of cases (12/13). Next generation sequencing (NGS) detected SS18- SSX1 fusion in 2 cases and SS18- SSX2 fusion in 1 case. SS18- SSX1+ S18- SSX2 fusion was found in 1 case, and one case of SS18- NEDD4 fusion occurred. Preoperative neoadjuvant chemotherapy was performed in 2 cases, postoperative chemotherapy in 11 cases, postoperative chemoradiotherapy in 2 cases, and surgery only in 5 cases. All patients were followed up for 3 to 42 months, and 4 cases were lost to follow-up. Patients with younger onset had a longer cumulative survival time. Patients had a median survival time of 13 months and a mean survival time of 15.4 months. Conclusions:PRSS is more common in middle-aged men, the right kidney is easy to occur, the length of the mass is usually >7 cm, most cases can be initially diagnosed by pathologic morphology, immunophenotype, fluorescence in situ hybridization or NGS STY gene detection can provide accurate diagnosis. The prognosis of PRSS is very poor, and the cumulative survival rate is negatively correlated with the age of onset. Surgical resection combined with chemotherapy is the main treatment for PRSS.
