Pediatric series consists of elastic nail,correction plate,pediatric proximal femoral locking plate,LC-DCP locking plate,reconstruction locking plste,T locking plate.
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.).

Application of Several New Plant Pesticides on Fruits and Vegetables
Plant-based pesticides are natural alternatives to synthetic chemical pesticides, derived from various plant sources. These eco-friendly options are widely used in the production of pesticide-free agricultural products, offering a safer and more sustainable approach to pest management. They are effective against a range of pests while minimizing environmental impact and ensuring crop safety.
Cnidium is a well-known source of natural insecticides. The active compound, osthol, is extracted from the mature fruits of *Cnidium monnieri*, a member of the Umbelliferae family. It is available as a 0.4% emulsifiable concentrate (EC). Osthol works primarily through contact toxicity, with some stomach poisoning effects. It is particularly effective against pests such as cabbage worms, cruciferous vegetable caterpillars, and tea tree pests. For the prevention of cruciferous vegetable cabbage worms, it is recommended to apply 80–120 ml of 0.4% EC per 667 square meters, diluted in 50–75 kg of water. Similarly, for controlling tea tree pests, 100–120 ml of the same concentration is used. The treatment remains effective for about seven days and is safe for crops.
Celangulin is another natural pesticide derived from the root bark and seeds of *Euonymus* shrubs. It is formulated as a 1% emulsifiable concentrate (EC) and is known for its strong stomach poison, antifeedant, repellent, and contact-killing properties. It is especially effective against the cabbage white butterfly (*Pieris* spp.). A typical application rate is 50–70 ml of 1% EC per 667 square meters, diluted in 60–75 kg of water. The product acts quickly, achieving over 90% control within one day, and remains effective for more than seven days. It is also considered safe for use on crops.
Sanguinarine, an alkaloid extracted from plants in the Papaveraceae family, is another key ingredient in plant-based pesticides. It is available as a 1% wettable powder (WP), with a 5% total alkaloid formulation. Sanguinarine shows moderate efficacy against pests like cabbage caterpillars, bean aphids, apple aphids, two-spotted spider mites, and pear hibiscus. For cruciferous vegetables and cabbage caterpillars, 30–50 g of 1% WP per 667 square meters is recommended, with best results when applied during the early larval stage. For apple aphids and two-spotted spider mites, the product should be diluted 1500–2500 times and sprayed evenly on the affected areas. While the initial effect is moderate, the efficacy improves significantly after three days, with a residual effect lasting up to seven days and no harm to the crops.
Cineole, the main component of eucalyptus oil, is used in a 5% solution formulation. It is effective against pests that affect cruciferous vegetables. The recommended dose is 70–100 ml of 5% solution per 667 square meters, mixed with 75 kg of water for even spraying. The treatment remains effective for about seven days and is safe for the crops. This makes it a reliable option for organic farming practices.
