Based on the innovative development trend brought by industrial internet in America，industry 4.0 in Germany and integration of informatization and industrialization policy in China，from the perspective of power generation enterprise，the thinking of Guohua Power on the development of“three-in-one”construction framework of smart power station，and the detailed design scheme using“one control and three management”center，the“APS+field bus”digital technology application and“one body two wings three promotion”information construction as the core，were stated. Following this blueprint，program management approach was innovated，the problem that the implementation workis multiple，complex and strongly relevant was solved，initial results in six areas was achieved，the overall operation level of power plant was improved，and experience for the development of smart power industry in China was accumulated.

Background In recent years, studies have demonstrated the use of ultrasound speckle tracking techniques for the early evaluation of subclinical left ventricular (LV) systolic function in patients with type 2 diabetes mellitus (T2DM). In addition, long-term exposure to hyperglycemia severely damages the microvascular system. However, the interaction between diabetic microvascular complications and subclinical LV systolic function has not been fully understood. Objective To investigate the relationship between subclinical LV systolic function and diabetic microvascular complications in patients with T2DM. Methods A total of 150 patients with T2DM who were admitted to the Department of Endocrinology, the First Affiliated Hospital of Air Force Medical University from June to December 2021 were selected in the cross-sectional study and all underwent conventional echocardiography, pulsed tissue Doppler echocardiography and two-dimensional speckle tracking echocardiography (2D STE). The 2D global longitudinal strain (GLS) of LV was obtained to assess the subclinical LV systolic function. Diabetic microvascular complications were defined as combined diabetic retinopathy, diabetic kidney disease or peripheral neuropathy. The subjects were divided into the T2DM alone group (T2DM alone group, n=76), the T2DM with 1 complication group〔T2DM+C (1) group, n=37〕 and the T2DM with 2 to 3 complications group〔T2DM+C (2 to 3) group, n=37〕 according to the cumulative number of microvascular complications. The general demographic characteristics and biochemical indices of patients in the three groups were compared. The relationship between microvascular complications and subclinical LV systolic function was assessed by using Spearman correlation analysis and Logistic regression analysis. Results GLS was lower in the T2DM+C (1) and T2DM+C (2 to 3) groups than in the T2DM alone group (P
