Polysaccharide from Gynostemma pentaphyllum Makino (GPP) could prevent H22 tumour growth and have immunostimulatory in mice, but the mechanism is largely unknown. In this study, we further investigated whether GPP prevents tumour growth by inducing cytotoxicity to the tumour cells or enhancing immunity in H22 ascites tumour-bearing mice. The results showed that GPP prevented the H22 ascites tumour growth in vivo, but showed little effect on cell viability and cycles to H22 cells in vitro. GPP improved the proportion and mitochondrial level of T cells, and promoted the secretion of IL-2 and IFN-γ in the ascites of the mice. Furthermore, GPP in vitro enhanced the cell viability and promoted activation (in particular T cells), proliferation, and the secretion of IL-2 and IFN-γ of lymphocyte. Taken together, our results demonstrated that GPP prevents H22 ascites tumour growth by enhancing immunity rather than cytotoxicity in mice.
Abstract Background Whether and to what extent serum uric acid (SUA) mediates the association between combined lifestyle behaviors and type 2 diabetes mellitus (T2DM) remain unclear. This study aimed to investigate the role of SUA in the relationship between healthy lifestyle scores (HLS) and the incidence of T2DM. Methods This prospective study used data from Zhejiang Metabolic Syndrome cohort. A HLS (5-point scale including healthy waist circumference (WC), never smoking, high physical activity, healthy diet and moderate alcohol intake) was estimated in 13,919 participants, who had SUA at baseline examination in 2009–2014, and were followed-up to 2021–2022 to ascertain incident of T2DM. Cox proportional hazards models and mediation analysis were used to examine the associations between HLS, SUA and T2DM. Results We included 13,919 participants aged 18 years or older without diabetes at baseline (mean age 54.6 [SD 13.9] years, 58.7% female). During a median follow-up of 9.94 years, 645 cases of T2DM occurred. Compared with participants with a poor HLS, those with 4–5 low-risk lifestyle factors showed a 60% reduction in the risk of developing T2DM (adjusted HR, 0.40; 95% CI: 0.28–0.57). Further, the population-attributable risk percent (95% CI) of T2DM for poor adherence to the overall healthy lifestyle (< 4 low-risk factors) was 43.24% (30.02%, 56.46%). The HLS was inversely associated with SUA level. With per score increased in HLS, the beta (95% CI) of SUA (log transformed) was − 0.03 (− 0.03, − 0.02), and the odds ratio (95% CI) of hyperuricemia was 0.82 (0.77, 0.86). The relationship between the HLS and risk of T2DM was mediated by SUA with a 13.06% mediation effect. There was no significant combined effect of HLS and SUA on risk of T2DM ( P = 0.097). Conclusions The relationship between overall healthy lifestyle behaviors and T2DM was reconfirmed and the association appeared to be mediated by SUA. The mediation effect of baseline SUA was more pronounced among women who were below 60 years old.
Hereditary transthyretin amyloidosis (ATTR) is an autosomal dominant rare disease caused by heterozygous mutations in the TTR gene, which encodes depolymerized transthyretin deposited in several organs. An induced pluripotent stem cell (iPSC) line of ATTR was generated from peripheral blood mononuclear cells of a 28 years old male patient carrying the TTR mutation p.Phe53Val. We used non-integrated episomal vectors to achieve the reprogramming of PBMCs, and further proved pluripotency by expression of typical stemness surface markers, gene expression of pluripotency genes and the pathological evidence of teratoma forming three germ layers in vivo. This iPSC line is a useful cellular model for screening potential therapeutic targets and studying the pathogenic mechanism of disease.
Causes of social anxiety come from a variety of sources, and one of the earliest causes is parenting styles. Children’s consistent development of social anxiety may result from the use of different parenting styles by parents and social anxiety can persist into adulthood and even affect a person's whole life. In this paper, the author uses a questionnaire consisting of the s-EMBU-C scale and the Shyness Scale to examine the interaction between parenting styles and social anxiety in adults. A total of 420 effective data were collected in this study, after analysis, it was found that the age group of the respondents in this survey was still concentrated in their 20s overall, although some were individually higher. In the s-EMBU-C, no significant difference was found between the scores of the paternal factors and the maternal factors in the same dimension. In the Shyness Scale, more respondents selected low-scoring items, but the number of extremely high scores was high, so the overall scores were moderately high. Age was significantly associated with all factors in both s-EMBU-C and Shyness Scale. s-EMBU-C was significantly correlated with several factors in Shyness Scales. No clear regression prediction was found for the present survey data after regression prediction by SPSS. Although the findings of this study show a correlation between Parenting Styles and adult social anxiety, the author concludes that there are many other factors may influence adult social anxiety. Parenting Styles only partially affect adults’ social anxiety levels.
Hereditary transthyretin amyloidosis (ATTRv) is a rare, fatal, autosomal dominant disease with more than 140 mutations discovered. Three phenotypes of amyloid infiltration are neuropathy (ATTRv-PN), cardiopathy (ATTRv-CM), and neuropathy + cardiopathy (ATTRv-MIX). The lack of ATTR-specific biomarkers, difficulties in biopsy evidence, and limited known pathogenic mechanisms have made diagnosis difficult. Newly emerging noninvasive measures for monitoring progression and disease-modifying therapies have improved early diagnosis and patient management. Our research applies the latest technology, Data-Independent Acquisition-Based Quantitative Proteomics (DIA), to reveal comprehensive plasma protein profiles in the natural history of Chinese patients with hereditary transthyretin amyloidosis (ATTRv). We analyzed differentially expressed proteins (DEPs) in three phenotypes (ATTRv-PN, ATTRv-CM, and ATTRv-MIX). Serum samples were collected from a total of 18 patients (6 ATTRv-PN, 5 ATTRv-CM, and 7 ATTRv-MIX patients) and 20 healthy participants as a control group. Combined with the results of the proteomic and bioinformatic analyses, we found 30 DEPs and protein interaction networks clustered in KRT family proteins and DSC3 between ATTRv-PN and the control, which were rich in the estrogen signaling pathway and the cell adhesion molecule (CAM) pathway. This study demonstrates a global and significant proteomic profile in different stages of ATTRv.
Traditional teaching mode of fashion design is mainly focused on offline teaching. With the development and popularization of computer network technology, eLearning has become a new trend from the perspective of teaching practice. This paper aims to promote the interdisciplinary integration of modern information technology and fashion design education to break the discipline boundaries and strengthen the relationship between disciplines. In conclusion, students' thinking is expanded upon to show the diversity of the classroom environment. Furthermore, the application of Online to Offline (O2O) blended teaching mode in practical courses of fashion design is discussed, which contributes to actively guiding students to inquiry-based personalized learning.
Abstract Adventitious root (AR) formation is critical for cutting survival and nutrient absorption re-establishment. This complex genetic trait involves the interplay of nitrogen, endogenous hormones, and several key genes. In this study, we treated GL-3 apple ( Malus domestica ) in vitro shoots with nitrate and ammonium to determine their impact on AR formation, hormonal content, and gene expression patterns. Nitrate treatment significantly promotes adventitious rooting by increasing cell division, differentiation, and AR primordia formation compared to ammonium treatment. Elevated indole-3-acetic acid (IAA), reduced abscisic acid, and zeatin riboside concentrations were consistently observed with nitrate, likely crucial for promoting ARs over ammonium. Furthermore, Malus domestica auxin resistance1 ( MdAUX1 ) expression was induced, increasing IAA levels. MdIAA23 was upregulated. Further results indicate that the higher expression levels of Malus domestica WUSCHEL-related Homeobox gene 11 ( MdWOX11 ), Malus domestica lateral organ boundaries domain gene 16 ( MdLBD16 ), and MdLBD29 , and increased cell cycle-related gene expressions, contribute to auxin-stimulated adventitious rooting under nitrate conditions. In conclusion, this study establishes that auxin content and associated genes related to root development and cell cycle contribute to superior ARs in response to nitrate.
Cableways have been widely used in industrial areas, cities, and scenic spots due to their advantages, such as being a convenient mode of transportation, time-saving, labor-saving, and low cost, as well as offering environmental protection. To ensure the safe operation of a cableway, based on the characteristic that the velocity of the cableway bracket is approximately zero in a static deformation monitoring environment, a deformation monitoring method called zero velocity update (ZUPT)-based GNSS/IMU tightly coupled algorithm with the constraint of the Earth's rotation angular velocity was proposed. The proposed method can effectively solve the problem of a single GNSS being unable to output attitude, which is directly related to the status of wire ropes and cable cars. Meanwhile, ZUPT is used to restrain the Kalman filter's divergence when IMU is stationary. However, the improvements of ZUPT on attitude are not obvious, so the constraint of the Earth's rotation angular velocity was applied. The performance of the proposed method was evaluated through monitoring the cableway bracket of the Yimeng Mountain Tourism area in Shandong. Compared with the ZUPT-based GNSS/IMU tightly coupled algorithm (ZUPT-TC), the proposed method can further constrain the error accumulation of IMU while stationary and, therefore, it can provide reliable position and attitude information on cableway brackets.
