Method and system for gastric ablation and gastric pacing to provide therapy for obesity, motility disorders, or to induce weight loss

Method and system to provide therapy for obesity, gastric motility, or to induce weight loss comprises ablating the gastric tissue around the “pacemaker” region of the stomach, and electrically pacing the stomach with a pulse generator/stimulator to control the electrical activity of the gastric muscle. The ablation to the gastric tissue may be from the epigastric side, or may be from inside the stomach. The ablation may be performed utilizing any one of: radiofrequency catheter ablation; radiofrequency catheter ablation using an irrigated tip catheter; microwave ablation; cryoablation; high intensity focused ultrasound (HIFU) ablation; and laser ablation. The ablation of the “pacemaker” region of the stomach may be partial or complete. A gastric pulse generator/stimulator is implanted to provide electrical pulses to the stomach. The function of the gastric stimulator after complete ablation of the pacemaker region, is to provide a basic electrical rhythm (BER) to regulate and control electrical activity of the stomach. Alternatively, if partial ablation is performed the function of the gastric pulse generator/stimulator is to enhance the residual basic electrical rhythm (BER), or to interfere with the residual basic electrical rhythm (BER).

Method for plicating and fastening gastric tissue

A method for creating a plication within a hollow organ. The method uses an elongated member having an end effector attached to its distal end. The end effector has a substantially hollow housing, a fixed jaw extending distally from the housing, and a retractable jaw located within the housing. The method involves the step of inserting the end effector within an organ of a patient such that it is in contact with tissue. The method also involves applying vacuum through the elongated member so as to dispose tissue on the fixed jaw and at least partially within the housing. The method also involves creating a plication by sliding the retractable jaw so that it juxtaposes the fixed jaw.

Gastric cancer extremely-early cell marker, gastric cancer precancerous lesion early cell marker and application of markers in diagnostic kits

The inventor finds out a cell population (named as gastric cancer very early cells) which starts to appear in the low-grade heteroplasmal hyperplasia stage of the stomach, has specific molecular characteristics and has a high canceration risk, and the cell population can be used as a marker for very early diagnosis of gastric cancer. Molecular markers of gastric cancer extremely-early cells are applied to preparation of a kit for realizing early diagnosis of gastric cancer or other digestive system tumors based on gastric tissues or blood samples. The gastric cancer extremely-early cell markercan also distinguish the postoperative recurrence risk of gastric cancer and the tumor risk of digestive system organs such as intestines, pancreas and esophagus. Besides, the inventor also finds outa cell population which appears in the early stage of gastric precancerous lesions and has specific molecular characteristics, and the cell population can be used as a marker for early diagnosis of gastric precancerous lesions and is also integrated into the kit. The markers and kits can be used for early clinical diagnosis of gastric cancer and other digestive tract tumors, can also be used as an intervention target for prevention and treatment of the digestive tract tumors, and have a good application prospect.

Composite self-emulsifying soft haematococcus pluvialis astaxanthin capsule as well as preparation method and application thereof

The invention discloses a composite self-emulsifying soft haematococcus pluvialis astaxanthin capsule as well as a preparation method and an application thereof. The soft capsule comprises a capsule core and a capsule wall, and the capsule core contains haematococcus pluvialis astaxanthin or haematococcus pluvialis astaxanthin extract, vegetable oil, an emulsifier, a co-emulsifier and an antioxidant. The vegetable oil, the antioxidant and haematococcus pluvialis astaxanthin are stirred uniformly, a mixed emulsifier is prepared from an obtained solution with the emulsifier and the co-emulsifier, uniform stirring and filtration are performed, and a self-emulsifying system is obtained; a soft capsule material liquid and the self-emulsifying system are added to a soft capsule making machine, and the composite self-emulsifying soft haematococcus pluvialis astaxanthin capsule is obtained. The soft capsule is prepared from haematococcus pluvialis astaxanthin and the optimized vegetable oil byreasonable combination, has high dispersibility and excellent storage stability, and can enhance anti-fatigue ability and learning and memory ability of an aging model rat, improve activity of SOD (superoxide dismutase) in gastric tissue, reduce MDA (malondialdehyde) content and scavenge free radicals in vivo.
