Hand skeletal features of children and adolescents with different growth statuses and periods.

Background: The hand skeletal features of children and adolescents at different growth statuses and development periods, and the correlation between these skeletal features and hand asymmetric force are currently unclear. Thus, this study sought to investigate the hand skeletal features of children and adolescents at different growth statuses and at different periods of development, and the correlation between these skeletal features and asymmetric force in hands.

Methods: A retrospective study was performed on subjects aged 4-20 years with good growth status (group A) or short stature (group B).

Images of giant cell tumor and chondroblastoma around the knee: retrospective analysis of 99 cases.

Background: It is difficult to differentiate giant cell tumors of the bone (GCTB) from chondroblastoma around the knee based on imaging findings. This study analyzed the imaging features of these 2 diseases for better differentiation.

Methods: This retrospective cross-sectional cohort study reviewed data of patients with pathologically confirmed GCTB (n=81; age 15-75 years; median age 33 years) and chondroblastoma (n=18; age 12-34 years; median age 14 years).

Clinical and Imaging Features of Desmoplastic Fibroma of Bone for Correct Diagnosis and Differentiation.

Objective: The objective of this study is to analyze the clinical and imaging features of desmoplastic fibroma of bone (DFB) for correct diagnosis.

Materials And Methods: Twenty patients with DFB confirmed by pathology were enrolled, and the imaging presentations were analyzed. Among 20 patients, plain X-ray was performed in all patients, computed tomography (CT) was performed in 12, and magnetic resonance imaging (MRI) was conducted on eight.

Clinical and Imaging Features of Tumors in the Scapula.

Background: The scapula is a small irregular-shaped flat bone, which may suffer from a variety of tumors or tumor-like lesions. As the imaging manifestations are complex and changeable, correct imaging diagnosis is difficult.

Introduction: At present, there are few related radiology literatures, and it is necessary to fully analyze the imaging signs of different types of benign and malignant tumors in scapula to guide clinical treatment.

Imaging features of hemangioma in long tubular bones.

Background: To investigate the imaging features of hemangiomas in long tabular bones for better diagnosis.

Methods: Twenty-four patients with long bone hemangiomas confirmed by pathology were enrolled. Nineteen patients had plain radiography, fourteen patients had computed tomography (CT) and eleven had magnetic resonance imaging (MRI).

Enough positive rate of paraspinal mapping and diffusion tensor imaging with levels which should be decompressed in lumbar spinal stenosis.

Introduction: In lumbar spinal stenosis, correlating symptoms and physical examination findings with decompression levels based on common imaging is not reliable. Paraspinal mapping (PM) and diffusion tensor imaging (DTI) may be possible to prevent the false positive occurrences with MRI and show clear benefits to reduce the decompression levels of lumbar spinal stenosis than conventional magnetic resonance imaging (MRI) + neurogenic examination (NE). However, they must have enough positive rate with levels which should be decompressed at first.

Suppression of CDK2 expression by siRNA induces cell cycle arrest and cell proliferation inhibition in human cancer cells.

Cyclin-dependent kinase 2 (CDK2) is a member of serine/ threonine protein kinases, which initiates the principal transitions of the eukaryotic cell cycle and is a promising target for cancer therapy. The present study was designed to inhibit cdk2 gene expression to induce cell cycle arrest and cell proliferation suppression. Here, we constructed a series of RNA interference (RNAi) plasmids which can successfully express small interference RNA (siRNA) in the transfected human cells.
