According to the above content, it can be concluded that non-invasive high frequency shock ventilation has obvious clinical efficacy in the treatment of neonatal respiratory distress syndrome. Compared with non-invasive continuous positive airway pressure (CPAP), non-invasive high-frequency concussion ventilation can improve the respiratory distress of children more effectively, and shorten the length of ventilator use and hospital stay. After treatment, blood gas indexes of the children were also significantly improved, PaCO2 was decreased and PaO2 was increased. Therefore, non-invasive high frequency shock ventilation is an effective treatment.

Objective: To investigate the relationship between the influential factors, administration methods and international standard ratio (INR) of warfarin anticoagulant therapy after mechanical heart valve replacement. Methods: 123 patients with mechanical heart valve replacement were followed up. Warfarin anticoagulation was used after surgery, and regular follow-up was conducted after discharge. Age, gender, warfarin dose and INR value were recorded, and the occurrence of adverse events such as bleeding, embolism and death were observed. Results: There were no death cases after operation. Femoral vein thrombosis occurred in 1 case, gingival bleeding in 11 cases and urinary system bleeding in 3 cases. The incidence of adverse events due to anticoagulation during discharge follow-up was similar to that reported in foreign literatures. Conclusion: 5 days after mechanical heart valve replacement, individualized dose according to INR can achieve certain anticoagulant effect and is relatively safe when INR value is controlled between 1.5 and 2.0.

Rumination plays an important role in depression. It is a passive, repetitive pattern of response in which individuals focus their attention on the symptoms, causes, and consequences of depression, and plays a vital role in the maintenance of affective disorders. Studies have shown that depressive rumination is strongly associated with both seasonal and non-seasonal depression. Depressive rumination has an impact on depression by increasing negative thought content, interfering with effective problem solving, and reducing social support, among other mechanisms. Future research could further explore the relationship between depressive rumination and various mechanisms of influence, as well as aspects of cognitive behavioral therapy for depressive rumination.

The obstacle avoidance trajectory planning of AGV in complex dynamic obstacle environment is transformed into an optimal control problem. The motion constraints, collision avoidance constraints and two-point boundary conditions of AGV are established. The distance between the final stopping position and the desired position of AGV is taken as the optimization objective. This paper proposes and applies an improved A; + direct collocation "combinatorial optimization algorithm is used to solve the optimal control problem. In the time dimension of this algorithm, A is adopted. The algorithm searches out the path nodes with the lowest path cost, and takes these nodes as the initial locus points of the optimal control problem. Because of the cusp of the initial trajectory, it cannot meet the kinematic constraints of AGV, so it needs to be optimized by combining the direct collocation method. The optimal control problem is discretized into a nonlinear programming problem with constraints, and the interior point method is used to search for optimization. A numerical example shows that this method can effectively search for an initial trajectory without collision, and optimize the trajectory under the condition of meeting the kinematic constraints, so as to realize the obstacle avoidance of AGVs in dynamic environment.
