The profiles ran through the Xiadian fault and the Ershilichangshan fault. The profiling result shows that the crust in this region is divided into the upper crust, the lower crust and the crust-mantle transitional zone by two powerful laminated reflectors: one at the two-way travel-time of about 7.0s (21km), the other at about 11.0～12.5s (33～37km). Crustal structure varies significantly in vertical direction. The shallow part is characterized by obvious stratification, multilayers and complexity. The upper crust on the whole features reflection “transparency”, while the lower crust features distinct reflectivity. Crustal structure also varies a lot in the lateral direction. The main fracture in this region is the deep fault under the Xiadian fault. This deep fault is steeply inclined (nearly vertical), and is supposed to be the causative fault of the Sanhe-Pinggu M8.0 earthquake. The two profiles respectively reveal the existence of local strong reflectivity in the lower crust and the lower part of the upper crust, which is assumed to be a dike or rock mass formed by the upwelling and cooling down of materials from the upper mantle. Magmatic activity in this part brought about differences in regional stress distribution, which then gave rise to the formation of the deep fault. That is supposed to be the deep structural setting for the Sanhe-Pinggu M8.0 earthquake.展开更多

Methods: the experiment started in May 2021 and ended in May 2022. In this time frame, a total of 103 patients with diabetic nephropathy were collected in our hospital, all of whom were treated with hemodialysis. The grouping method was single and double serial number method. Presentation: control group, 51 cases, routine nursing;the observation group, 52 cases, received systematic nursing intervention. Blood glucose index, complications, quality of life, comfort, emotional state and compliance were used as comparison indexes between the two groups. Results: fasting blood glucose and 2h postprandial blood glucose in the observation group were lower than those in the control group. Complications in the observation group were less than those in the control group;the scores of quality of life, comfort and compliance in the observation group were higher than those in the control group. Compared with Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD), the scores of the observation group were lower (P < 0.05). Conclusion: in the selection of the best nursing scheme, systematic nursing intervention is beneficial to hemodialysis of diabetic nephropathy patients. It can not only improve blood sugar, control complications, but also improve patients quality of life and comfort, showing a positive and optimistic psychological state, which can be popularized.展开更多
