Adaptable cascaded registration for personalized maxilla completion and cleft defect volume estimation.

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.

[Pollution Characteristics and Sensitivity of Surface Ozone in a Typical Heavy-Industry City of the North China Plain in Summer].

The pollution characteristics of surface ozone and its response to meteorological factors and precursors were studied based on monitoring and Model-3/CMAQ modeling from May to August 2018 in Handan City, China. The monitoring results showed that the maximum daily 8-hour average ozone concentration (MDA8 O) ranged from 38.0-238.

Complete Sequence of a Novel IncR-F33:A-:B- Plasmid, pKP1034, Harboring fosA3, blaKPC-2, blaCTX-M-65, blaSHV-12, and rmtB from an Epidemic Klebsiella pneumoniae Sequence Type 11 Strain in China.

A high fosfomycin resistance rate was observed in Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (KPC-KP) in our previous study, but little is known about its mechanisms. 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.

[Surgical treatment for incomplete Tessier No.3 craniofacial cleft: report of three cases and review of literature].

Objective: To primarily assess the surgical technique to correct incomplete Tessier No. 3 craniofacial cleft.

Methods: From 2009 to 2010, 3 male patients with incomplete Tessier No.

[Division of flap in cleft palate patients after posterior pharyngeal flap surgery].

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.

[Application of computer aided design and rapid prototyping technology for defected maxilla restoration].

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.

Effect of Zn7-metallothionein on oxidative stress in liver of rats with severe thermal injury.

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.
