The application belongs to the technical field of biological medicine, and relates to application of a CXCL14 inhibitor in preparation of a drug for preventing or treating abdominal aortic aneurysm of a patient. The inhibitor effectively eliminates the gender difference of abdominal aortic aneurysm by specifically blocking the combination of CXCL14 and its receptor CXCR4, significantly reduces aortic macrophage infiltration and PDGFRA + macrophage accumulation in the progress of abdominal aortic aneurysm, reduces the degree of collagen degradation and elastic fiber damage, and thus inhibits the pathological progress of abdominal aortic aneurysm. The application provides a new target and drug combination for precise treatment of male abdominal aortic aneurysm, and has clear clinical application value.

Systems, methods, and devices for internal wound treatment include a hemostasis device. The hemostasis device has an insertion tube extending from a base portion. One or more openings are formed into a surface of the insertion tube. Additionally, the hemostasis device includes an inflation pump couplable to a proximal of the insertion tube for pumping air into an inner channel of the insertion tube. A wound channel balloon is disposed at least partially around the insertion tube such that an actuation of the inflation pump causes the air to flow from the inner channel through the one or more openings and inflate the wound channel balloon. The wound channel balloon can include a grooved elastic fiber, one or more bulges, and / or one or more branches. Furthermore, a collagen gel, an antibiotic, a blood clotting agent, an analgesic, stem cells, a sealant, and / or a lubricant can be disposed on the wound channel balloon.

The invention belongs to the technical field of biological medicines, and relates to application of a CXCL14 inhibitor in preparation of a medicine for preventing or treating abdominal aortic aneurysm of a patient. The inhibitor effectively eliminates the sex difference of the abdominal aortic aneurysm by specifically blocking the combination of CXCL14 and a receptor CXCR4 thereof, significantly reduces aortic macrophage infiltration and PDGFRA + macrophage accumulation in the progress process of the abdominal aortic aneurysm, and reduces the collagen degradation and elastic fiber destruction degrees, thereby inhibiting the pathological progress of the abdominal aortic aneurysm. The invention provides a new target spot and a medicine composition for precise treatment of male abdominal aortic aneurysm, and has a definite clinical application value.

The utility model relates to the technical field of child trampoline, and discloses an outdoor child trampoline with an anti-rollover stable structural design, which comprises an elastic trampoline surface, a safety protection net component and an anti-rollover support frame component, the elastic rope assemblies are evenly distributed between the elastic trampoline surface and the trampoline outer frame, elastic cloth is further arranged between the elastic trampoline surface and the trampoline outer frame, and the elastic cloth cover and the elastic trampoline surface form a certain inclination angle. The elastic cloth is made of high-elasticity fiber materials. Through the design of the safety protection net component and the anti-rollover supporting frame assembly, the overall stability of the trampoline is remarkably improved, rollover accidents are effectively prevented, and the safety of children is ensured; meanwhile, through optimal configuration of the elastic cloth and the elastic rope assembly, the elasticity and durability of the trampoline are enhanced, the service life of the trampoline is prolonged, and the user experience is improved.

A vascular treatment device for use in a vessel includes a catheter and a microvalve occluder. The occluder includes braided elastic strands, each with a proximal portion, a central portion, and a distal portion, that are fixed to the outer surface of the catheter. The elastic strands. In an embodiment, the distal portions are attached circumferentially about an outer surface of the catheter at a location toward the distal end of the catheter, the central portions extend proximal and radially outward from the distal end, and the proximal portions of the strands are inverted back radially within the central portions are and coupled circumferentially about the outer surface of the catheter at a location proximally displaced from the distal portions. The proximal portion of the microvalve is coated in a fluid-impermeable membrane, and the distal portions of the strands are substantially uncoated.
