The invention discloses a fixed stress release hole load reduction method in a soft foundation layer, which comprises the following steps: drilling a hole in the soft foundation layer between a pile foundation and a pile load, implanting a fixed stress release hole device, arranging a soil guide hole towards the pile load during implantation, regularly cleaning a soil body flowing into the device through the soil guide hole, and carrying out stress release on the fixed stress release hole device; and grouting in the pipe when deformation monitoring of the pile foundation shows deformation convergence. When a foundation soil body generates lateral displacement under the loading effect, the foundation soil body can enter the fixed stress release hole device through the soil guide hole, and a regular cleaning and digging maintenance mechanism is matched to ensure that the stress release channel is continuously in an effective working state. According to the invention, the technical bottleneck of no stress release effect caused by easy collapse of a traditional stress release hole or stress unloading failure after the stress release hole is filled with a lateral moving soil body is fundamentally solved, so that the hollow pipe array can be used as a permanent barrier for blocking stacking lateral displacement; and long-term passive bearing safety of pile foundations of adjacent buildings (structures) is ensured.

The invention provides a needle assisting device. The needle assisting device implants the sensor into target tissue through percussion. The needle assisting device comprises a supporting piece, an operating piece and a percussion seat. The proximal end of the support is in contact with the skin of a user. The operating part is arranged around the supporting part and can move relative to the supporting part in the far and near direction.

Inventors have synthesized peptides allowing an engagement of intact CD31 molecules on all the healthy endothelial cells and resting blood platelets and leukocytes that can enter in contact with an implanted device. Those cells can therefore receive the “leave-me-alone” signal delivered by the trans-homophilic engagement of CD31, which is essential to maintain the homeostasis in the circulation and vascularized tissues. Thrombotic or life-threatening occurrence of hemorrhagic or thromboembolic complications have impaired the use of endovascular devices. The devices bearing the mimicking peptides of the present invention are rapidly integrated, because they are perceived by blood platelets and leukocytes as a healthy endothelium, a “self” component. Furthermore, their ability to be rapidly endothelialized with a physiologic endothelial cell phenotype also limits platelet and leukocyte activation at the site of device implantation in the long-term. Accordingly, the present invention relates to peptides mimicking the trans-homophilic CD31-CD31 domain 1 and 2 intercellular interaction.
