请注意代码缩进和格式，将两个程序整合成一个：

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MyWindow()
    sys.stdout = window  # 将标准输出重定向到 print 输出信息框中
    print("print 成功")
    window.show()
    sys.exit(app.exec_())
    
    while (1):
        cols = ['0', '1', '2', '3', '4', '5', '6', '7']
        line_names = ['VitalSigns1', 'VitalSigns2', 'VitalSigns3', 'VitalSign4', 'VitalSign5', 'VitalSign6',
                      'VitalSign7', 'VitalSigns8']
        nowfile = time.strftime('%Y-%m-%d-%H-%M-%S', time.localtime())
        if excel_name != None and over != 0:
            df1 = pd.read_excel(excel_name, sheet_name='Sheet1')
            plt.plot(df1[cols[0]], label=line_names[0])
            plt.plot(df1[cols[1]], label=line_names[1])
            plt.plot(df1[cols[2]], label=line_names[2])
            plt.plot(df1[cols[3]], label=line_names[3])
            plt.plot(df1[cols[4]], label=line_names[4])
            plt.plot(df1[cols[5]], label=line_names[5])
            plt.plot(df1[cols[6]], label=line_names[6])
            plt.plot(df1[cols[7]], label=line_names[7])
            plt.legend()
            plt.xlabel('NUM DATA')
            plt.ylabel('LIFE DATA')
            plt.title('Title of the plot')
            plt.savefig(nowfile, dpi=300)
            plt.show()
            over = 0
        main()
