The invention provides a lead-acid accumulator raw plate solidification drying process which is used for solving the problems that the raw plate active matter is easy to occur argillization, and be desquamated, etc. The technical proposal of the invention is that the procedure is carried out in a solidification drying chamber, with the process parameters as follows: 60 to 95 percent of solidification relative humidity of positive raw plate, 30 to 45 DEG C of solidification temperature thereof, 56 to 72 hours of solidification time thereof; 60 to 80 percent of solidification relative humidity of negative raw plate, 30 to 45 DEG C of solidification temperature thereof and 36 to 48 hours of solidification time thereof. The process of the invention is beneficial for reducing the free lead content in the raw plate, obviously improves the adhesion of the lead paste and the grid plate, prolongs the service life of the accumulator, and reduces the generation of rust plate and the dosage of water vapor during the solidification. The comparison detection indicates that the service life of the accumulator prepared by the raw plate which is processed by the process of the invention is prolonged by about 20 percent compared with the original process.

An orthopedic device and method for correcting angular deformation of a bone structure having a growth plate. The device includes first and second hinge members connected together at a hinge joint. The device is adapted for mounting the orthopedic device to the bone structure with the pivot joint positioned over the growth plate. Alignment of the pivot joint with the growth plate promotes asymmetric growth of the growth plate to thereby correct the angular deformation.

A nanotube based device for guiding a beam of x-rays, photons, or neutrons, includes a beam source and at least one nanotube. Each nanotube has an optical entrance positioned in a manner that a projection of the direction of the central axis at the optical entrance intersects with the beam source. Each nanotube may have an interior diameter that varies along the length of the nanotube. to point the entrances of a bundle of nanotubes toward a point-shaped beam source, the bundle can be grown as an array of multilayer nanotubes from a spherical growth plate. The clear aperture of the bundle is enhanced by providing a smaller number of wall layers of each nanotube near the growth plate than at a distance from the growth plate.

Under a special condition, the size of the bone screw can be adjusted according to the ankle osteotomy, ankle fracture degree and the growth plate characteristics of ulna.

A means of measuring and monitoring skeletal growth rate using a plasma analyte, amino-terminal C-type natriuretic peptide (NT-CNP). Plasma NT-CNP concentrations reflect the potential for further growth of the immature skeleton. Measurement of plasma NT-CNP in a subject, when related to the mean of an appropriate age and gender matched set of control subjects, provides an index of the severity of a growth disorder not otherwise available and facilitates diagnosis in children with undetected osteo-chondrodysplasias or other intrinsic disorders of the growth plate. The invention also provides a means of detecting and monitoring potentially harmful effects of drugs and other factors on skeletal growth long before they are evident using current methods in clinical practice.

The technological scheme includes sampling over 600 children of 1-10 years old as measuring check samples; measuring the sound velocity in the children's radius and treating the measured results to obtain the average children's bone sound velocity as the standard value of average children's bone sound velocity in the said age range; and measuring the bone sound velocity and bone growth plate sound velocity of the measured child and comparing with the standard value so as to evaluation result of the bone age and bone growth plate development degree of the measured child. The present invention avoids the jamming on the measurement process and opens one new way of judging child's bone age and bone growth plate development degree objectively and quantitatively.

An implantable apparatus for use in the correction of skeletal deformities comprising a hinge applied in various orientations across one or more growth plates and attached to bone via attachment members.

An implant has a soft tissue attachment structure, and a surface defining a trough. An ingrowth plate spans a portion of the trough and defines a suture tunnel between the ingrowth plate and the trough for receiving suture. The ingrowth plate bows convexly away from the surface and is perforated to facilitate long-term ingrowth and biologic fixation of soft tissue to the implant.
