Objective To investigate the protective effects of empagliflozin, a highly selective SGLT-2 inhibitor, on cardiac function in mice with acute myocardial infarction (AMI) and to explore its mechanism. Methods Thirty-four 6- week-old male C57BL/6J mice were randomly divided into the sham group (n=11), model group (n=11) and treatment group (n=12) . AMI was induced in the model group and treatment group by left anterior descending (LAD) artery ligation. The mice in the sham group underwent the same procedure except that the LAD was not ligated. The mice in the treatment group were given empagliflozin (10 mg/kg/day, oral gavage) at 4 h after MI surgery for 7 days. The mice in the sham group and model group were given 0. 5% hydroxyethyl cellulose. The left ventricular internal dimension in diastole (LVIDd), left ventricular internal dimension in systole (LVIDs), fractional shortening (FS) and ejection fraction (EF) were measured by echocardiography in all three groups. TUNEL staining was used to measure cardiac apoptosis. Blood samples were collected on day 7 after AMI to measure serum levels of NLRP3, ASC, Caspase-1, IL-1β, IL-18 and CRP by ELISA. The expression levels of NLRP3, ASC, Caspase-1, cleaved Caspase-1, IL-1β, and IL-18 were analyzed by Western blotting. Results There was no difference in LVIDd among these groups (P>0. 05). Compared with the sham group, the treatment group and model group had increased LVIDs (both P<0. 05). Compared with the sham group, the treatment group and the model group had decreased EF and FS, increased serum levels of NLRP3, IL-1β, IL-18, CRP, and up-regulated protein levels of NLRP3, ASC, cleaved Caspase-1, IL-1β, and IL-18 in the cardiac tissues of mice, with much more significant changes in the model group (all P<0. 05). The mice in the model group had significantly higher cardiac apoptosis rate than the sham group and the treatment group (both P<0. 05), while there was no statistical difference between the sham group and the treatment group (P>0. 05). There was no significant difference in the serum levels of Caspase-1 between the sham group and the model group (P>0. 05). Similarly, no statistical difference was found in the protein level of Caspase-1 in the cardiac tissues of mice among all three groups (P>0. 05). Conclusion Empagliflozin improves cardiac function and reduces cardiomyocyte apoptosis in AMI mice, and its mechanism may be related to the inhibition of the NLRP3/ASC/Caspase-1 signaling pathway and reduction of the inflammatory response.

Maintaining the authority and centralized and unified leadership of the CPC Central Committee is a major subject of Marxist party construction. The central authority of Marxist political parties emphasizes the dialectical unity of compulsory power and conscious obedience, leading core and leading collective, centralization and democracy. The central authority is of great significance to maintaining the cohesion of Marxist party organization, the efficiency of policy implementation and the strategic choice of the party at the important moment. Scientific theoretical guidance, the authority of the leadership core, democratic centralism, party discipline and system construction are important mechanisms to safeguard the central authority of Marxist political parties. Socialism with Chinese characteristics has entered a new era, the "two establishments" should be put into practice, and the "core consciousness" should be strengthened. Under the leadership of political construction and on the basis of ideological construction, we should constantly improve the construction of democratic centralism and institutional system, and transform the "two establishments" into the political consciousness, ideological consciousness and action ability of "two maintenance".

The calibration processes of current distributed hydrological model has been a critical issue in data-scared or ungauged regions. In this study, we setup a hydrological model, in which, the variable saturated zone concept originated from the real-time interactive basin simulator is applied for runoff generation and the grid water droplet method for flow concentration. We also proposed a method for parameter estimation based on the characteristics of underlying surface. Based on field infiltration experiments and parameter sensitivity analysis, the quantitative statistical relationships were built between two sensitive parameters (surface saturated hydraulic conductivity K0z, coefficient of attenuation of saturation hydraulic conductivity with depth f) and the topographic parameters and soil types. The overland confluence parameters were determined by field overland flow observation experiments. The proposed parameter estimation method was verified in selected basins. Our results showed that: ① The proposed method for K0z estimation contributes to a better modeling performance for flood simulation in Jiangwan experimental watershed, the average Nash- Sutcliffe efficiency coefficient increased from 0. 82 to 0. 86, and the average absolute values of peak and flood volume errors decreased by 2. 2% and 0. 95%, respectively, but the average absolute value of the peak present time error increased by 4% (still controlled within 2 h). ② Using the measured flood data of 14 basins such as Jiangwan to calibrate the parameter f, we established the quantitative relationship between the calibrated parameter f and the soil type data of different depths was built in 14 basins including Jiangwan, and further tested in other six basins. The parameter f estimated by the soil type data of different depths was very close to that determined by traditional model calibration processes, the average absolute relative error is 2. 8%, the average Nash-Sutcliffe efficiency coefficient of the flood simulation is 0. 83, and the average absolute values of flood peak error and flood volume error were 10. 07% and 6. 86%, respectively, and the average absolute peak present time error was 2. 61 h. Our results indicated that the proposed methods for determining sensitive runoff generation parameters are applicable in data-sparse areas and could provide a better or comparable parameter estimation and flood simulation than that determine by field measurements, model calibration, remote sensing data estimation, and other methods.

This paper proposed an improved method for automatic extraction of multi-band spectral relationship of narrow and deep rivers in mountains and valleys with high sediment concentration from Landsat 8 OLI images, which overcame the mixed pixel effect of mountain shad ow and exposed bedrock in the downstream section of the reservoir. Taking Jingeun to Dongzhuang Reservoir section in the middle reaches of Jinghe River on the Loess Plateau as an example, it separated the water body and mountain shadow, bare mountain and bedrock beach by considering the characteristics of the multi-band spectral, and then constructed a water body extraction model suitable for narrow and deep rivers with high sediment concentration in valleys. Compared with other water extraction models, the method proposed in this paper can over come the influence of shadow close to river channel and bedrock downstream of reservoir on water extraction, and improve the extraction accuracy of narrow and deep rivers with high sediment concentration in mountain canyon.

Low-slope bedrock meandering rivers widely exist in areas controlled by geological structures (the bed slope is less than 5‰). Flood has a great influence on riverbed sedimentation and erosion in bedrock meandering rivers, however, we have a poor understanding of dynamic structure of flood for bedrock meandering rivers. By geometrically generalizing bedrock meandering reaches, considering the Froude similarity and side wall roughness, a generalized model of a bedrock meandering channel is established in order to analyze the water surface profile distribution, time average flow fields and turbulence structure characteristics for bends under flood. The results show that under the flood flow, the minimum water surface transverse gradient, separation of flow on the convex bank, development of double circulation on the concave bank, velocity-dip-phenomenon and maximum secondary circulation intensity are caused at the upstream of the bend apex, and the maximum water surface transverse gradient and circulation splitting are caused at the downstream of the bend apex; the bed shear stress is distributed in the flow separation area at the convex bank as well as the center of the upstream of the bend apex, and the transverse momentum transport is concentrated at the upstream of the bend apex. The experiment results show an explanation in view of hydrodynamics in respect to bed erosion and sedimentation in bedrock meandering rivers. [ABSTRACT FROM AUTHOR]
