INTRODUCTION: Visual impairment and obesity remain the major public health issues among school-age students in rural areas of China. Obesity is an underlying risk of vision problems. This study aimed to assess the association between visual impairment and body mass index (BMI) among school-age students in rural northwest China. METHODS: This study included 39,385 students from the 4 th to 9 th grade in rural northwest China. From 2018 to 2020, students underwent an assessment of visual acuity (VA) and completed a questionnaire on family demographics, and height and weight measurements. Multiple logistic regression analyses were used to analyse the data. RESULTS: The association between visual impairment and BMI groups was significant in the study population ( P = 0.002) and in different groups (at the different educational, provincial and national levels) ( P < 0.001, separately). Multiple logistic regression analyses revealed a positive relationship between visual impairment and obesity in the study population, including those attending primary school, Han students and the residents of Ningxia autonomous region. CONCLUSION The association between visual impairment and obesity was significant among school-age students in rural northwest China. There should be implementation of policies to address the problem about visual impairment and obesity among school-age students in rural areas.

Objective To investigate the mechanism by which angiopoietin-like protein 8(ANGPTL8)regulates vascular smooth muscle cell(VSMCs)apoptosis.Methods An in vitro abdominal aortic aneurysm cell model was established by stimulating human VSMCs(HUSMCs)with angiotensin Ⅱ(AngⅡ).Stable ANGPTL8 knockdown and over-expression VSMC cell strains were generated using lentiviral transfection.TUNEL staining was used to de-tect apoptosis.Western blot analysis was performed to measure the protein expression of ANGPTL8,caspase9,caspase3,Bcl-2,Bax,p53,and PUMA,while RT-qPCR was used to assess mRNA expression of ANGPTL8,Bcl-2 and Bax.Results AngⅡ significantly induced ANGPTL8 expression in HVSMCs in a time-and dose-de-pendent manner(P＜0.05).ANGPTL8 knockdown significantly reduced the expression of apoptosis-related proteins caspase9,caspase3,and Bax,while increased the expression of the anti-apoptotic protein Bcl-2(P＜0.05).Con-versely,ANGPTL8 over-expression markedly induced HVSMCs apoptosis,which was significantly suppressed by treatment with the p53 pathway inhibitor pifithrin-α(PFT-α).Conclusions ANGPTL8 may promote VSMC apop-tosis by activation of p53 signaling pathway.

BACKGROUND:Basketball shoes are one of the most important pieces of athletic equipment in basketball,helping to improve players'performance and reduce the risk of injury.With the development of basketball,the demand for basketball shoe performance is getting higher and higher.OBJECTIVE:To systematically review and summarize the effects of different functional parameters of basketball shoes on the wearer's biomechanical performance,and to investigate the effects of each functional parameter of basketball shoes on athletic performance and injury risk.METHODS:Relevant literature addressing the effect of basketball shoes'functional parameters on human biomechanics from CNKI,WanFang,Web of Science,ScienceDirect and other databases was searched by computer,with the search terms of"basketball,basketball shoe,shoes,footwear,sports biomechanics,kinematics,kinetics"in Chinese and English.All the retrieved literature was evaluated and screened,and finally 61 articles were included for literature review.RESULTS AND CONCLUSION:Existing studies on functional parameters of basketball shoes include shoe collar height and heel counter-stiffness,midsole hardness,midsole cushioning,midsole thickness,forefoot flexural stiffness,whole shoe mass,and outsole traction.The functional parameters of basketball shoes play a role in improving sports performance and reducing the risk of sports injuries:(1)Compared with low-top shoes,high shoe collars can reduce the risk of ankle sprains,but may affect sports performance,ankle proprioception,and increase the load on the knee.(2)Better midsole cushioning or softer midsoles can effectively reduce vertical impact,and the forefoot cushioning structure can effectively improve the athletic performance of lateral movement.(3)The midsole thickness of 11 mm in the forefoot and 20 mm in the rearfoot can obtain the best ankle stability and sprinting performance.(4)Improving the outsole traction and forefoot bending stiffness can significantly improve the performance of jumping,sprinting,and side-cutting.There are diminishing returns to the improvement of athletic performance by improving outsole traction.(5)Lighter basketball shoes can improve athletic performance,but this effect only occurs when the wearer is aware of the shoes'weight.

Artemisia argyi (A. argyi), a plant with a longstanding history as a raw material for traditional medicine and functional diets in Asia, has been used traditionally to bathe and soak feet for its disinfectant and itch-relieving properties. Despite its widespread use, scientific evidence validating the antifungal efficacy of A. argyi water extract (AAWE) against dermatophytes, particularly Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporum gypseum, remains limited. This study aimed to substantiate the scientific basis of the folkloric use of A. argyi by evaluating the antifungal effects and the underlying molecular mechanisms of its active subfraction against dermatophytes. The results indicated that AAWE exhibited excellent antifungal effects against the three aforementioned dermatophyte species. The subfraction AAWE6, isolated using D101 macroporous resin, emerged as the most potent subfraction. The minimum inhibitory concentrations (MICs) of AAWE6 against T. rubrum, M. gypseum, and T. mentagrophytes were 312.5, 312.5, and 625 μg·mL^-1, respectively. Transmission electron microscopy (TEM) results and assays of enzymes linked to cell wall integrity and cell membrane function indicated that AAWE6 could penetrate the external protective barrier of T. rubrum, creating breaches ("small holes"), and disrupt the internal mitochondrial structure ("granary"). Furthermore, transcriptome data, quantitative real-time PCR (RT-qPCR), and biochemical assays corroborated the severe disruption of mitochondrial function, evidenced by inhibited tricarboxylic acid (TCA) cycle and energy metabolism. Additionally, chemical characterization and molecular docking analyses identified flavonoids, primarily eupatilin (131.16 ± 4.52 mg·g^-1) and jaceosidin (4.17 ± 0.18 mg·g^-1), as the active components of AAWE6. In conclusion, the subfraction AAWE6 from A. argyi exerts antifungal effects against dermatophytes by disrupting mitochondrial morphology and function. This research validates the traditional use of A. argyi and provides scientific support for its anti-dermatophytic applications, as recognized in the Chinese patent (No. ZL202111161301.9).

Objective To analyze the clinical characteristics and genotype of a patient with congenital systemic lip-odystrophy(CGL)type 1 associated with exudative xanthoma caused by AGPAT2 gene mutation,and to provide ev-idence for clinical and genetic diagnosis of the disease.Methods Clinical data of the patient such as medical histo-ry,physical examination and laboratory examination were collected.Peripheral venous blood was collected for whole exome sequencing analysis and Sanger sequencing verification,and treatment was provided to patients according to the changes of condition.Results The clinical manifestations of the patient were subcutaneous fat reduction,fatty liver,spleen enlargement,kidney enlargement,high blood sugar and lipids,severe insulin resistance,scattered yellow rash on limbs,which was confirmed as xanthoma.The results of whole exon sequencing showed that the AGPAT2 gene of the patient had a heterozygous nonsense mutation of c.202C＞T:p.R68?and c.646A＞T:p.K216?,and the former was the pathogenic mutation site.Follow-up therapy covers improvement of lifestyle,low-fat diet and regular exercise.The rashes subsided after active lipid-lowering therapy.Conclusions Apart from typical lipody-strophy,the patient was accompanied by exanthemous xanthoma.No CGL1 patient with exanthemous xanthoma has been reported in the domestic literature database up to now,and the genetic test results showed that there was a c.202C＞T heterozygous mutation of AGPAT2 gene.This gene site has not been reported in the literature,and its functional verification needs to be further studied.

Dermatomyositis is an autoimmune disease involving the skin and muscles. At the onset of dermatomyositis, it is difficult to make an early diagnosis due to atypical clinical manifestations and lack of serological markers. Skin and muscle lesions are associated with disease activity and prognosis in patients with dermatomyositis or clinical amyopathic dermatomyositis. Computed tomography, magnetic resonance imaging, ultrasonography, dermoscopy and other imaging techniques may be used to assess skin and muscle involvements, which can not only improve the accuracy of early diagnosis of dermatomyositis, but also provide important reference for the assessment of disease activity and prognosis.
