An abdominal exercise device comprises a center bar, a handle assembly attached to a first end portion of the center bar and that is adapted to be grasped by a user, an abdominal press assembly mounted to the center bar between first and second end portions thereof and having an abdominal contact surface that is spaced from the center bar and is adapted to rest against an abdominal region of a user; and a stabilizer mounted to the second end portion of the center bar and that is adapted to stabilize the center bar when the abdominal contact surface rests against a user. The user can perform a leg lift exercise, a crunch exercise, or both exercises in unison.

The invention discloses an absorbable chitin-based composite patch and an application thereof. The absorbable chitin-based composite patch is a mesh composed of chitin-based fibers or threads respectively having a surface coating; the chitin-based fibers or threads are insoluble in water, the main chain of the molecular structure of the chitin-based fibers or threads is polyglucosamine and contains an acyl group and a hydrophilic group, the total molar percent content of the acyl group is greater than or equal to 70%, and the total molar percent content of the hydrophilic group is less than 30%; and the surface coating is a water-soluble aminoglycan coating. The absorbable chitin-based composite patch is implanted in an abdominal wall in the operations of abdominal wall defect repairing and hernia repairing, can reduce the inflammatory response in the acute stage, reduce abdominal adhesions, promote the growth of the tissue cells and the synthesis of an extracellular matrix and accelerate the defect repairing of the abdominal walls in the physiologic repairing stage after the operation, and is gradually degraded after the abdominal wall defect repairing, and degradation products are absorbed and utilized by local tissue cells to further promote the abdominal wall defect repairing, so the absorbable chitin-based composite patch has no residual in bodies after being completely degraded, and no foreign matters exist in the bodies.

Belonging to the field of organic polymer compound preparation or chemical processing, the invention provides a tension-free hernia patch and a preparation method thereof. The patch provided in the invention has good toughness and strength match, no adverse reaction in the human body, and excellent biocompatibility, and is free of inflammation and foreign body reaction. When the patch is implanted into organisms, abdominal adhesions and intestinal fistulas are greatly reduced, so that the patch is a good material for incisional hernias, abdominal hernias, stomal hernias, umbilical hernias and other herniorrhaphies. The patch includes a basal layer made of a non-absorbable material and a surface coating made of an absorbable material. The surface coating is softer, and can be completely absorbed by the human body in 60 days, thus providing time for combination of the basal layer and surrounding tissues. The patch provided in the invention has a simple preparation process and a low manufacturing cost. As a medical tension-free hernia patch, it has excellent comprehensive performance, and is a safe and reliable patch, thus having great social and economic value.

The invention relates to the application of VEGF monoclonal antibody combined with nano-paclitaxel in the preparation of drugs for the treatment of cancerous abdominal adhesions and a composition of VEGF monoclonal antibody combined with nano-paclitaxel. The VEGF monoclonal antibody and nano-paclitaxel are combined to form a complex, which can be used in the treatment of cancerous abdominal adhesions. Abdominal adhesions have unexpected technical effects. Compared with the treatment of VEGF monoclonal antibody alone, the symptoms of abdominal adhesions and intestinal obstruction can be improved more obviously, and the toxic and side effects are less. In addition, the use of chitosan nano-encapsulated VEGF monoclonal antibody combined with nano-paclitaxel can make the duration of action longer and can regulate the time and intensity of action. While the curative effect is further enhanced, toxic side effects are further reduced, and the probability of complications occurs.
