Background: Cone-beam computed tomography (CBCT) images provide high-resolution insights into the underlying craniofacial anomaly in patients with cleft lip and palate (CLP), requiring non-negligible annotation costs to measure the cleft defect for the guidance of the clinical secondary alveolar bone graft procedures. Considering the cumbersome volumetric image acquisition, there is a lack of paired CLP CBCTs and normal CBCTs for learning-based anatomical structure restoration models. Nowadays, the registration-based method relieves the annotation burden, though one-shot registration and the regular mask are limited to handling fine-grained shape variations and harmony between restored bony tissues and the defected maxilla.

The monitoring results showed that the maximum daily 8-hour average ozone concentration (MDA8 O) ranged from 38.0-238.

In this study, we explored the prevalence of plasmid-mediated fosfomycin resistance determinants among fosfomycin-resistant KPC-KP strains from a Chinese university hospital and determined the complete sequence of a novel fosA3-carrying plasmid isolated from an epidemic K.

Objective: To investigate the reasons of flap division in patients with posterior pharyngeal flap and the outcome of the flap division for treating secondary velopharyngeal insufficiency (VPI) and obstructive sleep apnea-hypopnea syndrome (OSAHS).
Methods: Twenty patients who underwent flap division after posterior pharyngeal flap surgery were included in this study, including 11 incomplete cleft palate and 9 complete cleft palate). Nasal endoscopy and lateral cephalometric radiographs were performed for all the patients preoperatively.

Objective: To test a new cast-making method based on computer aided design (CAD) and rapid prototyping (RP) technology for defected maxilla.
Methods: Head CT data of 12 patients with defected maxilla were transmitted into a computer. Three-dimensional digital image of the patient's defected maxilla was then obtained based on Mimics 8.
Aim: Using the model of burned animal with delayed resuscitation to study antagonistic effect of Zn7-metallothionein (Zn7-MT) on oxidative stress in the liver of rats suffered from severe thermal injury on skin.
Methods: To compare the changes in antioxidant concentrations and antioxidative enzyme activities in the liver or plasma of burned rats with or without Zn7-MT in resuscitation fluid by biochemical assay.
Results: After injury, glutathione concentration was progressively decreased with time.
