关键词： 黔西南蜡染   纹样符号   编织   纱线刺绣   融合应用  

摘要： 为了拓宽国家级非物质文化遗产蜡染的应用途径,提出一种蜡染纹样与编织刺绣美学设计的创新融合方案。首先通过文献调研法归纳与分析黔西南苗族蜡染服饰中几何、动物、植物3类纹样的特点及象征寓意;然后提取传统的蜡染元素纹样并进行抽象化处理,经由解构重组、色彩分析后形成富含民族美学价值的编织刺绣图案;最后借助纱线编织刺绣技法应用于抱枕、坐垫、手提袋和白T恤等纺织品上,既增强了纺织品面料的立体感和凹凸感,又赋予其丰盈质感和灵动色彩。传统蜡染纹样与编织工艺的融合拓宽了蜡染纹样在纺织品设计应用中的发展路径,丰富了产品设计表达。

摘要： Transforming growth factor beta 1 (TGF-β1) is considered a pleotropic cytokine involved in the progression of cardiovascular disease. The purpose of the current study was to identify the relationship between serum levels of TGF-β1, the genetic variations (C509T rs1800469, T869C rs1800470) and their constructed haplotypes with the susceptibility of ischemic heart disease (IHD) in the Iraqi population. The case-control study enrolled 200 participants, including 100 patients with IHD and 100 healthy controls. Genotypes of (TGF-β1) polymorphisms were performed by TaqMan allele-specific probes detected by real-time PCR (RT-PCR). The serum level of TGF-β1 was measured by an ELISA assay. The obtained results showed that the two minor alleles of C509T rs1800469 and T869C rs1800470 were associated with a decreased risk of IHD, preventive fraction (PF%) = 11.6 %; 23.9 %, respectively. Genotype distribution was significantly noted in the TT genotype of C509T rs1800469 (p = 0.033) and in the TC genotype of T869C rs1800470 (p = 0.006) between patients and control groups. A significant distribution was seen in the C allele of T869C rs1800470 (p = 0.002) between the studied groups. The carriers of the TT genotype in the C509T rs1800469 and the TC; CC genotypes in the T869C rs1800470 decreased the chance of having IHD, (hazard ratio HR<1). Furthermore, the haplotype analysis observed that H1 (C-T) was significantly associated with the development of IHD (HR=1.66; 95 % CI=1.10–2.51; p = 0.021) and the inverse effect of H4 (T-C), (HR=0.36; 95 % CI=0.20–0.65; p = 0.001). The TGF-β1 alleles of both SNPs, TT genotype of C509T rs1800469, TC, CC of T869C rs1800470 and H4 locus of haplotypes were suggested to be protective biomarkers against IHD in Iraqi population.

关键词： 冠心病   运动方式   心肺储备功能   运动耐力   网状Meta分析  

摘要： 目的:系统评价不同运动方式对冠心病患者心肺储备功能和运动耐力的效果。方法:检索中国知网(CNKI)、万方数据知识服务平台(Wanfang Data)、维普网(VIP)、中国生物医学文献服务系统(SinoMed)、PubMed、Web of Science、The Cochrane Library、Embase数据库中关于运动方式改善冠心病患者心肺储备功能和运动耐力的随机对照研究,检索时间为建库至2023年4月。由2名研究者独立筛选文献、提炼资料和评价纳入文献的偏倚风险后,选择RevMan 5.3、Stata 16.0、R4.2.2进行统计分析。结果:共纳入30项研究,2433例冠心病患者,网状Meta分析结果显示:在提高左室射血分数(left ventricular ejection fraction,LVEF)方面,最好的2种运动方式是有氧结合抗阻运动和有氧运动;在提高6分钟步行试验(six minutes walk test,6MWT)距离方面,最好的2种运动方式是抗阻运动和有氧结合抗阻运动;在改善肺功能方面,最好的2种运动方式是抗阻运动和瑜伽。但由于纳入研究的质量和数量等存在一定的局限性,仍需高质量研究进一步验证。结论:运动可以改善冠心病患者的心肺储备功能和运动耐力,但不同运动改善心功能的侧重点不同,其中有氧结合抗阻运动在提高LVEF和6MWT方面效果最显著,抗阻运动在提高6MWT和FEV1/FVC%方面效果较好。

关键词： Calliptamus italicus   RNAi   diapause termination   DIB   JHE   CAM  

摘要： BACKGROUND: Calliptamus italicus L. is a major pest in Xinjiang grassland. The diapause overwintering strategy is one of the important reasons for the large population of this pest. This study investigated the function of the genes associated with the release of diapause (DIB, JHE and CAM) in Calliptamus italicus by RNA interference (RNAi) technology to aid in its biological control. RESULTS: The expression levels of DIB and its downstream-associated genes (EcR and FTZ-F1) in the eggs injected with dsDIB for 12 h decreased by 96.6%, 55.8% and 81.8%, respectively. Diapause began to terminate on day 3, and development was almost complete on day 6. However, the head was significantly smaller. The expression levels of JHE and its downstream-associated genes (JHEH and VgR) at 48 h after dsJHE treatment decreased by 76.5%, 85.6% and 85.9%, respectively. The termination of diapause occured on day 3 of incubation. The development was basically complete on day 6, but the yolk had been incompletely absorbed. The expression of CAM and its downstream-associated genes (CAMK4 and MYL) at 24 h after dsCAM treatment decreased by 42.4%, 95.3% and 82.7%, respectively. Diapause termination was completed on day 4 for incubation, and development was abnormal on day 6. The absorption of yolk was incomplete. CONCLUSION: DIB, JHE and CAM can delay the diapause termination of Calliptamus italicus eggs to different degrees and can be developed as potential target genes for its biological control.

关键词： breast cancer diagnosis   BCaXAI   deep learning   mammogram imaging   Grad-CAM   explainable AI  

摘要： Breast cancer (BCa) poses a severe threat to women's health worldwide as it is the most frequently diagnosed type of cancer and the primary cause of death for female patients. The biopsy procedure remains the gold standard for accurate and effective diagnosis of BCa. However, its adverse effects, such as invasiveness, bleeding, infection, and reporting time, keep this procedure as a last resort for diagnosis. A mammogram is considered the routine noninvasive imaging-based procedure for diagnosing BCa, mitigating the need for biopsies;however, it might be prone to subjectivity depending on the radiologist's experience. Therefore, we propose a novel, mammogram image-based BCa explainable AI (BCaXAI) model with a deep learning-based framework for precise, noninvasive, objective, and timely manner diagnosis of BCa. The proposed BCaXAI leverages the Inception-ResNet V2 architecture, where the integration of explainable AI components, such as Grad-CAM, provides radiologists with valuable visual insights into the model's decision-making process, fostering trust and confidence in the AI-based system. Based on using the DDSM and CBIS-DDSM mammogram datasets, BCaXAI achieved exceptional performance, surpassing traditional models such as ResNet50 and VGG16. The model demonstrated superior accuracy (98.53%), recall (98.53%), precision (98.40%), F1-score (98.43%), and AUROC (0.9933), highlighting its effectiveness in distinguishing between benign and malignant cases. These promising results could alleviate the diagnostic subjectivity that might arise as a result of the experience-variability between different radiologists, as well as minimize the need for repetitive biopsy procedures.
