Logic may interact with a user to generate or modify a code block of adjustments for a prescription or interact with the user via two-dimensional or three-dimensional image(s) to generate or modify a correction path of the treatment plan for a bone fixator. Logic may generate the prescription based on a deformity correction associated with a code block or based on a deformity correction identified by the user by modifying existing waypoints and / or adding new waypoints to the correction path. Logic may generate a display of an image of a fixed and a moving bone segment connected to the bone fixator and adjust the display to show a state of the bone deformity and the bone fixator at a point in time of the prescription selected by the user.

The invention relates to an application of an STAT3 agonist ColivelinTFA in the treatment of HIES (High Immunoglobulin E Syndrome) and osteoporosis. An osteoblast specific Stat3 knockout mouse is constructed through a Cre-loxp system, it is found that the mouse shows HIES-related bone deformity such as maxillofacial bone development deformity, spontaneous fracture and osteoporosis, and the mechanism that STAT3 inactivation causes HIES-related bone development deformity and osteoporosis by regulating osteogenic activity is proved. On the basis, it is proved that the STAT3 agonist ColivelinTFA can be used for treating osteoporosis caused by insufficient single dosage of STAT3 and stress loss. Compared with a diphosphate drug, the ColivelinTFA increases the bone mass by promoting bone metabolism instead of inhibiting bone metabolism, which may avoid a series of complications such as jaw bone necrosis caused by diphosphate to a certain extent.
