Ultra-Sensitive and Wide Sensing-Range Flexible Pressure Sensors Based on the Carbon Nanotube Film/Stress-Induced Square Frustum Structure.

Flexible pressure sensors have attracted much attention due to their significant potentials in E-skin, artificial intelligence, and medical health monitoring. However, it still remains challenging to achieve high sensitivity and wide sensing range simultaneously, which greatly limit practical applications for flexible sensors. Inspired by the surface stress-induced structure of mimosa, we propose a novel flexible sensor based on the carbon nanotube paper film (CNTF) and stress-induced square frustum structure (SSFS) and demonstrated their excellent sensing performances.

Anti-Disturbance Sliding Mode Control of a Novel Variable Stiffness Actuator for the Rehabilitation of Neurologically Disabled Patients.

Lower limb exoskeletons are widely used for rehabilitation training of patients suffering from neurological disorders. To improve the human-robot interaction performance, series elastic actuators (SEAs) with low output impedance have been developed. However, the adaptability and control performance are limited by the constant spring stiffness used in current SEAs.

Icariin influences adipogenic differentiation of stem cells affected by osteoblast-osteoclast co-culture and clinical research adipogenic.

Objective: To build mouse osteoblast MC3T3-E1 and mouse osteoclast RAW264.7 co-culture system and to study the effect of icariin on the activity of osteoblasts and osteoclasts in the co-culture system.

Methods: In vitro acquisition and cultivation of mouse osteoblasts MC3T3-E1 and mouse RAW264.

[Analysis of clinical characteristics of 20 patients with pyogenic spondylitis].

Objective: To investigate the diagnostic value of clinical manifestation, laboratory examination and imaging changes for pyogenic spondylitis and to summarize the clinical characteristics of patients with pyogenic spondylitis.

Methods: The clinical data, of 20 patients with pyogenic spondylitis were diagnosed by histopathological examination from March 2012 to March 2015, were retrospectively analyzed. There were 9 males and 11 females, aged from 43 to 72 years old with an average of 58.

[CLASSIFICATION AND TREATMENT STRATEGIES OF SYMPTOMATIC SEVERE OSTEOPOROTIC VERTEBRAL FRACTURE AND COLLAPSE].

Objective: To investigate the classification and treatment strategies of symptomatic severe osteoporotic vertebral fracture and collapse.

Methods: Between August 2010 and January 2014, 42 patients with symptomatic severe osteoporotic vertebral fracture and collapse were treated, and the clinical data were retrospectively analyzed. According to clinical symptom and imaging materials, 23 cases were classified as type I (local pain, limitation of motion, no neurological symptom, and no obvious deformity), 12 cases as type II (slight neurological symptom and kyphotic Cobb angle < or = 30 degrees), and 7 cases as type III (severe neurological symptom and kyphotic Cobb angle >30 degrees).
