Objective To explore the effect of continuous nursing intervention on limb function and nursing quality after proximal femoral nail antirotation (PFNA) internal fixation for femoral intertrochanteric fracture in the elderly. Methods From February, 2017 to November, 2018, 100 elderly patients with femoral intertrochanteric fracture who underwent PFNA internal fixation in our hospital were randomly divided into control group (n = 50) and observation group (n = 50), who accepted routine nursing and continuous nursing respectively for three months. They were assessed with Harris score and visual analogue scale for pain (VAS) before and after the intervention. The postoperative nursing effect was compared. Results The Harris score increased in both groups after the intervention (t > 45.98, P < 0.001), and increased more in the observation group than in the control group (t = 15.03, P < 0.001). The VAS score decreased in both groups after the intervention (t > 16.33, P < 0.001), and decreased more in the observation group than in the control group (t = 9.749, P < 0.001). The effect of nursing was better in the observation group than in the control group (Z = -2.272, P = 0.023). Conclusion Continuous nursing intervention can significantly improve the limb function and nursing satisfaction of elderly patients with femoral intertrochanteric fracture after PFNA.

Objective To explore the prevention for hip dysplasia after pediatric spinal cord injury. Methods From March, 2017, the families of 47 children with spinal cord injury accepted education for preventing improper posture of sitting and sleeping and other interventions, and 23 of them were followed up for three months or more. Results New hip dislocation was found in one child, and 18 children developed almost normally in hip, the other four children with old hip dislocation did not worsen.Conclusion Intervention in time may prevent the hip dislocation in children with spinal cord injury.

Objective To explore the biological mechanisms of electroacupuncture (EA) for depression. Methods Forty male adult Sprague-Dawley rats were randomly divided into control group (n=8), model group (n=8), EA group (n=8) and fluoxetine group (n=8). Depressive models were established with lonely raising and chronic unpredictable mild stress. They were tested with Open-field Test, and the expression of phosphodiesterase 4 (PDE4)A and PDE4D in hippocampus was detected with RT-PCR. Results The cross and rear scores were significantly lower in the model group than in the control group (P<0.001), while it increased in the EA group and the fluoxetine group (P<0.001). Compared with the model group, the expression of PDE4A and PDE4D decreased in the EA group (P<0.001). Conclusion Electroacupuncture may relieve depression through inhibiting the expression of PDE4A and PDE4D.

Objective To explore the risk factors for postoperative agitation (PA) in patients with cerebral palsy (CP). Methods 199 patients with CP receiving selective posterior rhizotomy or lower limbs orthopedics under combined intravenous and inhalational anesthesia were reviewed. Results 30 patients suffered from PA (15%), who tended to be younger, less body mass, and administered less anesthetics.Conclusion It may prevent PA of sufficient intra-operative and postoperative analgesia, necessary psychological intervention and sedatives.
