According to Japanese media reports, the research team of the Multi-Cell System Formation Research Center of Japan's Institute of Physical Chemistry (located in Kobe City) published a research report on the online edition of the American Science Journal on the 10th of this month, confirming that iPS cells can restore eye sensitivity. . According to reports, the researchers showed that induced pluripotent stem cells (iPS cells) became visual cells of the retina and transplanted into the eyes of mice blinded by advanced "retinal pigmentation", and the mice became sensitized to the eyes. This is the first time that the use of iPS cells has been shown to restore photosensitivity.
Deputy project leader Bandai Daozi explained: "I think that at this stage, I can feel a little light and the horizon is slightly widened." She plans to use human iPS cells for verification and apply for clinical research within 2 years.
It is reported that the function of the visual cell is to receive light and then transmit it to the nerve cells of the retina. If the cells disappear due to degeneration, "retinal pigmentation" occurs, causing vision loss and even blindness.
The team's practice in the experiment was to give an electric shock after 5 seconds of light in the room where the mouse was located, so that the mouse learned to escape into the adjacent room in order to avoid electric shock when it felt bright. As a result, 9 mice were not escaped due to late "retinitis pigmentosa" blindness.

The special manifestations of pediatric fracture
(1) In children, soft tissue is loose, fascia is elastic, swelling after fracture is early, wide range, and often plaque.
(2) Pay attention to subperiosteal fracture, longitudinal percussion pain and local tenderness to consider the possibility of fracture.
(3) Children can be fever, generally below 38 degrees, caused by hematoma absorption.
(4) Identify the ossification center and epiphyseal plate, and add normal side control if necessary.
Characteristics of pediatric fracture repair
(1) The fracture heals quickly, and the younger the age, the faster the healing.
(2) The healing time of fracture is related to fracture site, fracture type, treatment method and individual situation.
(3) Joint stiffness occurred less.
(4) Have a certain shaping ability, the younger the age, the stronger the shaping ability, but the rotation deformity, the angular deformity inconsistent with the joint activity is more difficult to shape itself.
(5) Metaphyseal and shaft fractures due to hyperemia stimulate epiphyseal plate overgrowth, can cause temporary acceleration of limb growth, femur bone.It can overgrow by 0.8-2cm.
Principles of fracture treatment
The first is reduction, fixation, functional exercise. The principle is no longer to damage the epiphysis and epiphysis plate causing growth and development disorders. Manual reduction, plaster fixation, traction. Closed reduction and internal fixation. Open reduction, internal fixation (elastic needles, Kirschner needles, absorbable nails, absorption rods, various steel plates, external fixation brackets, hollow screws, etc.).
