Objective: To observe the effects of Tuina (Chinese therapeutic massage) combined with graded motor imagery (GMI) on the upper-limb motor function and quality of life (QOL) in patients with poststroke hemiplegia.Methods: A total of 216 patients with hemiplegia caused by stroke were randomized into two groups by tossing a coin, with 108 cases in each group. The control group was treated with GMI, and the observation group was given additional Tuina treatment for four weeks in total. Before and after the treatment, the Fugl-Meyer assessment for upper extremity (FMA-UE), supper-limb/hand Brunnstrom staging, box and block test (BBT) for hand, co-contraction ratio (CR) of the upper-limb muscles, visual analog scale (VAS) for shoulder pain, modified Ashworth scale (MAS), modified Barthel index (MBI), and short-form 36-item health survey (SF-36) were adopted for observation of the two groups. Results: After the treatment, the scores of FMA-UE, upper-limb/hand Brunnstrom staging, hand BBT, MBI, and SF-36 increased (P<0.05), and the CR of biceps brachii at flexion, the CR of triceps brachii at extension, and the scores of VAS and MAS decreased in both groups (P<0.05). The scores of FMA-UE, upper-limb/hand Brunnstrom staging, and hand BBT were higher in the observation group than in the control group after the intervention (P<0.05); the CR of biceps brachii at flexion and the CR of triceps brachii at extension were lower in the observation group than in the control group (P<0.05). After the treatment, the scores of MBI and SF-36 were higher in the observation group than in the control group (P<0.05), and the scores of VAS and MAS were lower in the observation group than in the control group (P<0.05). Conclusion: Tuina combined with GMI can produce more significant effects in improving the upper-limb motor function and QOL in patients with hemiplegia after stroke.

This study aims to explore the clinical value of the computer-aided diagnosis (CAD) system for early detection of the pulmonary nodules on digital chest X-ray. A total of 100 cases of digital chest radiographs with pulmonary nodules of 5-20 mm diameter were selected from Pictures Archiving and Communication System (PACS) database in West China Hospital of Sichuan University were enrolled into trial group, and other 200 chest radiographs without pulmonary nodules as control group. All cases were confirmed by CT examination. Firstly, these cases were diagnosed by 5 different-seniority doctors without CAD, and after three months, these cases were re-diagnosed by the 5 doctors with CAD. Subsequently, the diagnostic results were analyzed by using SPSS statistical methods. The results showed that the sensitivity and specificity for detecting pulmonary nodules tended to be improved by using the CAD system, especially for specificity, but there was no significant difference before and after using CAD system.
