Provided are a modified mesenchymal stem cell and culture supernatant thereof, and a pharmaceutical composition comprising said cell or culture supernatant thereof. The mesenchymal stem cell is capable of expressing: (1) a first protein, which is selected from FGF21 or a variant thereof, or a first fusion protein comprising the FGF21 or the variant thereof; and (2) a second protein, which is selected from GLP-1 or a variant thereof or a second fusion protein comprising the GLP-1 or the variant thereof. Also provided is the use of the modified mesenchymal stem cell and culture supernatant thereof, and the pharmaceutical composition comprising said cell or culture supernatant thereof in the treatment of metabolic diseases and in the preparation of a medicament for treating metabolic diseases.

Method of treating diabetes with FGF21 and GLP1 double gene-modified cell

An antenna and an electronic device are provided. The antenna includes a phase shifting unit, a reference electrode layer, and an antenna substrate; the phase shifting unit includes at least one phase shifter, each includes a first transmission structure, a second transmission structure, and a phase shifting structure therebetween; the reference electrode layer is provided with at least one and second first openings; the antenna substrate includes a first dielectric substrate, and a feed structure and at least one first radiation portion on a side of the first dielectric substrate away from the reference electrode layer; the feed structure includes at least one first and second feed ports; for each phase shifter, the first transmission structure is electrically connected to a corresponding second feed port through a corresponding first opening; and the second transmission structure is electrically connected to a corresponding first radiation portion through a corresponding second opening.

Antenna and electronic device

A slave-side propelling device for an interventional surgical robot and a controlling method for the device are provided. The rubbing part, the clamping part, the catheter rotating part and the moving stepping motor part are installed and fixed on the housing. The transmission part is configured to transmit the torque of the moving stepping motor part to the sliding part and the pushing part. The sliding part is configured to drive the guide wire to reciprocate. The pushing part and the clamping part cooperate to clamp or loosen the guide wire. The rubbing part is configured to drive the guide wire to rotate. The catheter rotating part is configured to clamp the catheter and push the catheter into or withdraw the catheter out of the blood vessel.

Slave-side propelling device and controlling method for interventional surgical robot

There is provided a phase shifter having a phase shift region and a peripheral region, and including a first substrate, a second substrate and a dielectric layer between such two substrates; the first substrate includes a first dielectric substrate, a first electrode and a first auxiliary structure; the second substrate includes a second dielectric substrate, a second electrode and a second auxiliary structure; the phase shift region includes overlapping regions; the first electrode and the second electrode are located in the phase shift region, and have orthographic projections, on the first dielectric substrate, overlapped at least partially in the overlapping regions; the first auxiliary structure is in the peripheral region and on a side, close to the dielectric layer, of the first dielectric substrate; the second auxiliary structure is in the peripheral region and on a side, close to the dielectric layer, of the second dielectric substrate.

Phase shifter and antenna

The method includes obtaining a distance value of a guide wire from an inner wall of cavity and a resistance value of the inner wall of cavity to the guide wire when the guide wire moves in the cavity and controlling the guide wire for corresponding movement according to a relationship between the distance value and a predetermined distance threshold value, and/or the relationship between the predetermined resistance threshold value. The alarm strategy through image and resistance detection multi-dimensionally, lead to low false alarm rate. Automatic error correction by automatic reverse motion avoids the risk of untimely correction in case of danger due to the user's stress during the movement, thus improving the overall automation of movement control of the intervention robot.

Safe, early warning method and system for guide wire movement of interventional surgical robot

Provided are a modified mesenchymal stem cell and culture supernatant thereof, and a pharmaceutical composition comprising said cell or culture supernatant thereof. The mesenchymal stem cell is capable of expressing: (1) a first protein, which is selected from FGF21 or a variant thereof, or a first fusion protein comprising the FGF21 or the variant thereof and (2) a second protein, which is selected from GLP-1 or a variant thereof or a second fusion protein comprising the GLP-1 or the variant thereof. Also provided is the use of the modified mesenchymal stem cell and culture supernatant thereof, and the pharmaceutical composition comprising said cell or culture supernatant thereof in the treatment of metabolic diseases and in the preparation of a medicament for treating metabolic diseases.
