The problem of micro-pressure waves caused by the high-speed train passing through the tunnel from the open line become more and more serious with the increase of the train speed. The combined buffer structure can better mitigate the impact of micropressure waves than the single type of buffer structure. In order to further alleviate the impact of micro-pressure waves on the surrounding environment of the tunnel, a buffer structure named ladder ventilation type combined buffer structure was proposed. Based on the standard κ-ε two-equation turbulence model ( κ is the turbulent kinetic energy, ε is dissipation rate) and the numerical simulation method, four ventilation window parameters were studied, including the ventilation distance, the ventilation ratio, the number of ventilation windows, and the position of ventilation windows. The initial compression wave pressure and pressure gradient caused by the train entering the tunnel with different ventilation windows were analyzed, and the optimum parameters of the combined buffer structure were obtained. The buffer structure has less impact on the maximum pressure of the initial compression wave, but more impact on the initial compression wave pressure gradient. When the ventilation distance is 4 m, the ventilation rate α is 36%, the number of ventilation windows is 2, and the position of ventilation windows is the top ventilation, it is the optimal working condition, and the mitigation effect on pressure gradient reaches 60.14%.

Objective To investigate the effect of the strong bone and muscle form ula on bone mineral density ( BMD ) and IL-17 level in ovariectomized ra ts. Methods Thirty SPF grade 6-month-old female SD rats were divided into Sham group ( 11 = 9) and model group ( n = 21) according to random number table. After 12 weeks, 3 rats were respectively se lected from the Sham group and OVX group for lumbar vertebrae BMD test to verify the success of modeling. Rats in the model group were divided into OVX group ( n = 6), ZGQJ group ( n = 6 ), and Alen group ( n = 6 ). Rats in ZGQJ group received the strong bone and muscle formu la. Rats in Alen group received alendronate sodium. After 12 weeks of the treatment, the rats were sacrificed. BMD of the lumbar vertebrae was detected with DEXA. The microstructure of the tibia was detected with micro-CT. The structure of the femur and spleen was observed with HE staining. Serum level of IL-17 was detected with ELISA. The level of IL-17 in the tibia was detected with immunofluorescent staining. The level of IL-17 in the spleen was detected with immunohistochemistry. Results Compared to that in OVX group, the lumbar vertebrae BMD in ZGQJ and Alen group increased significantly ( P
