Anatomical characteristics and potential gene mutation sites of a familial recurrent patellar dislocation.

Background: Recurrent patellar dislocation is the result of anatomical alignment and imbalance of restraint of bone and soft tissue. We investigate the anatomical characteristics of the knee joint in a family of patients with recurrent patella dislocation, and to screen the possible pathogenic genes in this family by whole exome sequencing in 4 patients and 4 healthy subjects, so as to provide theoretical basis for the pathogenesis of this disease.

Methods: The data related to patella dislocation were measured by imaging data.

RETRACTED: GZMB gene silencing confers protection against synovial tissue hyperplasia and articular cartilage tissue injury in rheumatoid arthritis through the MAPK signaling pathway.

Development of pulsed neutron uranium logging instrument.

This article introduces a development of pulsed neutron uranium logging instrument. By analyzing the temporal distribution of epithermal neutrons generated from the thermal fission of (235)U, we propose a new method with a uranium-bearing index to calculate the uranium content in the formation. An instrument employing a D-T neutron generator and two epithermal neutron detectors has been developed.

[Morphology-based criteria for ultrasonic assessment of axillary lymph node status in primary breast cancer].

Objective: To evaluate the morphology-based criteria for the ultrasonic assessment of axillary lymph node in primary breast cancer.

Methods: A total of 2256 T0-2N0 patients underwent axillary ultrasound preoperatively. Lymph nodes were classified as normal if no node was found or cortex thickness was even and < 3 mm; abnormal, (1) if cortex thickness was even but ≥ 3 mm or (2) focally thickened cortex ≥ 3 mm or (3) fatty hilum was absent.

[Association of single nucleotide polymorphisms of IL-1b with lumbar disc disease].

This study was to explore the relationships between (-511)T>C and (+3954)C>T single nucleotide polymorphisms(SNP) in IL-1beta gene with lumbar intervertebral disc disease. We analyzed (-511)T>C and (+3954)C>T SNP in IL-1beta gene by the polymerase chain reaction-restriction fragment length polymorphism and electrophoresis methods respectively in 81 cases with lumbar disc disease and 101 healthy controls. The relationship between (-511)T>C and (+3954)C>T SNP in IL-1beta gene and lumbar disc disease in two groups was measured, so does the relationship between (-511)T>C and (+3954)C>T SNP in IL-1beta gene and intervertebral disc degeneration in those younger than 45-year-old.
