引用

北京体育大学学报 2024年第4期47卷 144-156页

目的:探讨高强度间歇训练(high-intensity interval training,HIIT)对高脂喂养的载脂蛋白E(ApoE)敲除(Apo^(E-/-))小鼠骨骼肌氧化应激的改善作用以及肌肉因子β-氨基异丁酸(β-aminoisobutyic acid,BAIBA)在其中的可能调节机制。方法:9周龄健康雄性C57BL/6J小鼠和Apo^(E-/-)小鼠分别喂食标准和高脂饲料,其中C57BL/6J小鼠为基线对照组(WT,n=6),Apo^(E-/-)小鼠经高脂饲料喂养12周后随机分为Apo^(E-/-)安静组(Apo^(E-/-),n=10)和Apo^(E-/-)高强度间歇训练组(Apo^(E-/-)HIIT,n=10),Apo^(E-/-)HIIT组进行6周HIIT,WT和Apo^(E-/-)组在笼中自由活动。最后一次运动后48 h取小鼠两侧腿部腓肠肌进行氧化损伤、抗氧化及BAIBA生成相关指标的检测。随后采用L-BAIBA预孵育C2C12细胞,后用过氧化氢(H_(2)O_(2))诱导氧化应激,结合干预条件随机分为Control、H_(2)O_(2)和L-BAIBA+H_(2)O_(2)组。相差显微镜观察细胞形态,并检测细胞ROS水平和Nrf2介导的抗氧化通路的相关指标。结果:1)与WT组相比,Apo^(E-/-)组小鼠骨骼肌氧化损伤相关的4-HNE修饰蛋白、蛋白质羰基含量和ROS水平显著升高,而抗氧化相关的p-Nrf2蛋白表达和GSH含量显著降低;而与Apo^(E-/-)组相比,Apo^(E-/-)HIIT组小鼠骨骼肌4-HNE修饰蛋白和蛋白质羰基含量明显降低,p-Nrf2蛋白表达和GSH含量明显升高。2)Apo^(E-/-)HIIT组小鼠骨骼肌生成BAIBA的相关酶基因Acads和Hadha mRNA的表达水平显著高于Apo^(E-/-)组。3)与Control组相比,H_(2)O_(2)干预后C2C12细胞明显皱缩,活细胞数量降低,ROS水平显著增加;而与H_(2)O_(2)组相比,L-BAIBA+H_(2)O_(2)组活细胞数量增加,形态较饱满,ROS水平明显降低。4)与Control组相比,H_(2)O_(2)显著降低了细胞Nrf2、p-Nrf2及其介导的抗氧化酶SOD1、NQO1和CAT蛋白以及合成GSH的相关酶基因Gss、Gsr和Gclm mRNA的表达水平,并显著降低了细胞GSH含量;而L-BAIBA+H_(2)O_(2)组较H_(2)O_(2)组则显著增加了p-Nrf2、SOD1和NQO1蛋白以及Gss、Gsr、Gclc和Gclm mRNA的表达量,同时细胞GSH含量也显著增加。结论:6周HIIT降低了高脂喂养的Apo^(E-/-)小鼠骨骼肌的氧化损伤,其中肌肉因子BAIBA对Nrf2介导的抗氧化信号的激活可能起着一定的作用。

Objective: Precise prevention is more desired for cervical cancer due to the huge population, high prevalence of human papillomavirus(HPV) infection in China and the vision of screen-and-treat strategies in low-and middleincome countries(LMICs). Considerations of combining type-specific prevalence and attribution proportion to high-grade cervical intraepithelial neoplasia are informative to more precise and effective region-specific cervical cancer prevention and control programs. The aim of the current study was to determine the genotype distribution of HPV and attribution to cervical precancerous lesions among women from rural areas in North ***: A total of 9,526 women participated in the cervical cancer screening project in rural China. The samples of women who tested positive for HPV were retested with a polymerase chain reaction(PCR)-based HPV genotyping test. The attribution proportion of specific high-risk human papillomavirus(HR-HPV) types for different grades of cervical lesions was calculated by using the type contribution weighting ***: A total of 22.2%(2,112/9,526) of women were HR-HPV positive and HPV52(21.7%) was the most common HR-HPV genotype, followed by HPV58(18.2%), HPV53(18.2%) and HPV16(16.2%). The top three genotypes detected in HR-HPV-positive cervical intraepithelial neoplasia(CIN)1 were HPV16(36.7%), HPV58(20.4%), HPV56(15.3%). Among CIN2+, the most frequent genotypes were HPV16(75.6%), HPV52(17.8%),HPV58(16.7%). HPV16, 56, 58, 53, 52, 59, 68, and 18 combined were attributed to 84.17% of all CIN1 lesions,and HPV16, 58, and 52 combined were attributed to 86.98% of all CIN2+ ***: The prevalence of HR-HPV infection among women from rural areas in North China was high and HPV16, HPV58, HPV52 had paramount attributable fraction in CIN2+. Type-specific HPV prevalence and attribution proportion to cervical precancerous lesions should be taken into consideration in the development of vaccines and strategy for scr
