To improve the quality of the decompressed images, the concepts of reproduction, elimination and dispersal in BFA are firstly introduced into neural network in the proposed algorithm. Extensive experiments are conducted on standard testing images and the results show that the pro- posed method can improve the quality of the reconstructed images significantly.展开更多
目的:研究餐前负荷联合阿托伐他汀对2型糖尿病(T2DM)患者颈动脉斑块的影响。方法:采取前瞻性研究,以萍乡市人民医院2021年1-9月诊断并治疗的T2DM合并颈动脉粥样硬化斑块患者60例作为研究对象,采用信封法随机分为观察组及对照组,各30例...目的:研究餐前负荷联合阿托伐他汀对2型糖尿病(T2DM)患者颈动脉斑块的影响。方法:采取前瞻性研究,以萍乡市人民医院2021年1-9月诊断并治疗的T2DM合并颈动脉粥样硬化斑块患者60例作为研究对象,采用信封法随机分为观察组及对照组,各30例。观察组患者采取餐前负荷联合阿托伐他汀治疗,对照组采取阿托伐他汀治疗。比较两组患者的血糖、血脂、超声指标、治疗效果及不良反应之间的差异。结果:治疗后,观察组患者的总有效率(90.00%)显著高于对照组(56.67%),差异有统计学意义(P<0.05);两组患者的空腹血糖(fasting blood glucose,FBG)、糖化血红蛋白(hemoglobin A1c,HbA1c)、24 h平均血糖(MBG)、24 h血糖标准差(SDBG)均低于治疗前,且观察组患者的FBG、HbA1c及24 h MBG、24 h SDBG均低于对照组,差异均有统计学意义(P<0.05);两组患者血脂各项指标均优于治疗前,且观察组患者的血脂各项指标均优于对照组,差异均有统计学意义(P<0.05);两组患者颈动脉内膜中层厚度(IMT)、血管阻力指数(RI)、收缩期峰值血流速度(PSV)、舒张末期血流速度(EDV)均优于治疗前,且观察组患者的IMT、PSV均显著低于对照组(P<0.05),EDV高于对照组(P<0.05),两组治疗后RI比较,差异无统计学意义(P>0.05);两组患者治疗期间的发热、腹泻、皮疹发生率比较,差异均无统计学意义(P>0.05)。结论:2型糖尿病患者采取餐前负荷联合阿托伐他汀治疗,糖脂代谢显著改善,颈动脉斑块显著缓解,建议临床推广。展开更多
