Objective To explore the clinical diagnostic value of CYFRA21-1 in benign lung disease deriving from epithelium cells.Methods CYFRA21-1 level in serum and hydrothorax was determined by electrochemiluminescence immunoassay. The complex sandwich (KS 19.1 monoclonal antibody-CYFRA21-1[Ru(bpy)3]2+ labeled monoclonal antibody BMI 9.21) was fixed to the bead enclosed avidin by means of biotin-avidin combination, then the luminescence under the influence of perfluorotripropylamine and electric field luminous was tested for CYFRA21-1.Results The level of CYFRA21-1 in the group suffering from lung disease accompanied by complications was significantly higher than that of single lung disease group (P<0.01). CYFRA21-1 value in the elder group was significantly higher than that of the younger group (P<0.01).Conclusion The gerontal patients suffering from benign lung disease accompanied by complications should be given symptomatic treatment if their CYFRA21-1 level is elevated but CEA and NES was normal. Recheck the above indices two weeks later so as to identify the benign or malignancy of the disease.

Objective:To document the effectiveness of using a digital treadmill in rehabilitating the walking ability of patients with an incomplete spinal cord injury.Methods:Ninety-three patients with an incomplete spinal cord injury were randomly divided into a control group ( n=46) and a treatment group ( n=47). Both groups received routine rehabilitation, but the treatment group was additionally trained using a digital treadmill. Before and after 3 months of the treatment, the quadriceps strength of each patient was graded using Lovett muscle strength grades. Walking ability was quantified using the 10m walk test, the 6min walking endurance test and lower extremity motor scoring (LEMS). Gait parameters were recorded along with the maximum knee flexion and hip flexion angles. Ability in the activities of daily living was assessed using the modified Barthel index (MBI) and the functional independence rating scale (FIM). Results:After treatment, significant improvement was observed in the average quadriceps muscle strength, 10m walking time, 6min walking distance, LEMS score, step length, step speed, step frequency, maximum knee flexion angle, maximum hip flexion angle, MBI score and FIM score of both groups compared with before the treatment. Significantly greater improvement was observed in the treatment group′s average quadriceps muscle strength, 10m walking time, 6min walking distance, LEMS score, step length, walking speed, stride frequency, knee and hip flexion angles, and their average MBI and FIM scores.Conclusions:Rehabilitation training using a digital treadmill can improve the lower limb muscle strength, walking ability and gait parameters of patients with incomplete spinal cord injury, as well as their ability in the activities of daily living.
