ABSTRACT
Objective: To evaluate the clinical effect of transpedical interbody bone grafting in the treatment of i senile osteoporotic vertebral fracture
Methods: Eighty-six elders with osteoporotic vertebral fracture were selected and divided into a control group and a test group using random double-blind method. Patients in the control group were treated by short-segment transpedicular screw system internal fixation, while patients in the test group were treated by short-segment transpedicular screw system internal fixation in combination with transpedical interbody bone grafting. Operation related indexes and fracture recovery condition were compared between the two groups
Results: The overall effective rate of the test group was 93.02%, much higher than the control group [76.74%] [P<0.05]. The difference of operation duration, intraoperative bleeding volume, length of hospital | stay, fracture healing time, preoperative vertebral height loss and preoperative Cobb's angle between! the two groups had no statistical significance [P>0.05]. The postoperative pain score of the test group | was lower than that of the control group, and the difference was statistically significant [P<0.05]. The; vertebral height loss and Cobb's angle of the test group were superior to those of the control group at the last follow up, and the difference had statistical significance [P<0.05]. The incidence of internal fixator loosening of the test group was much lower than that of the control group [P<0.05]
Conclusion: Short-segment transpedicular screw system internal fixation in combination with transpedical interbody bone grafting shows favorable effects in the treatment senile osteoporotic vertebral fracture, resulting in mild pain and less loss of vertebral height and angle; hence it is worth promotion in clinic

Objective To establish a scientific and sensitive evaluation index system of nursing quality for cancer hospital. Methods The evaluation index system of nursing quality for cancer hospital was formulated based on literature,semi- structured interviews and expert group discussion. Then, developing the evaluation index system of nursing quality for cancer hospital by two rounds of Delphi consultation. Results The experts′ authority coefficient was 0.862. The nursing quality indicators included 5 first-level indicators,9 second-level indicators and 73 third-level indicators. The Kendall coordination coefficients of the importance of the three level indicators were 0.354,0.217,and 0.243, The Kendall coordination coefficients of the feasibility of the three level indicators were 0.234,0.313,and 0.339. Conclusions Scientific nature and concentration indicator system of nursing quality for cancer hospital was developed. It will be used to provide quantitative basis for the control of nursing quality in cancer hospital.
ABSTRACT
Objective To explore the safety and short?term efficacy of irreversible electroporation (IRE)ablation which is a novel ablation technology in unresectable hepatic neoplasms. Methods Patients with pathologically diagnosed as liver cancer or liver metastases were prospectively enrolled. The patients were not suitable for surgery with PS score ≤ 2. Exclusion criteria included who was not tolerate general anesthesia, severe liver and kidney dysfunction, and with cardiac pacemaker. A total of 16 patients were included in this study. There was 12 males and 4 females, aged 40 to 86 years with mean age (60 ± 10)y. Ultrasound and CT guided percutaneous IRE ablation was performed. Perioperative hemodynamic changes were reviewed. Liver and kindey function before and 7 d after ablation was compare by t test. The adverse reactions within 30 d after ablation treatment were recorded. CT and MR scans within 1 month were performed and the 30 d curative effect was evaluated by the modified RECIST criteria. Results All patients received IRE treatment successfully, and some patients experienced adverse reactions within 30 days after ablation, including abdominal pain in 7 cases, peritoneal effusion in 5 cases, hydrothorax in 4 cases, fever in 3 cases, cough, nausea and vomiting in 2 cases, biliary tract infection and thrombocytopenia in 1 case. After symptomatic treatment, these symptoms were improved. Severe complications, such as massive haemorrhage and bile leakage didn't occur. At 30 days after ablation, the curative effects were evaluated. Complete response (CR) was achieved in 1 patient , partial response (PR) was achieved in 12 patients, stable disease (SD) was in 2 patients , and progressive disease(PD) was 1 patients . The tumor relief rate (complete response+partial response) was 81.3%. Conclusions IRE ablation in the treatment of unresectable hepatic malignant tumor could have many advantages, including high safety, mild adverse reactions, and short?term efficacy. However, its long?term effect still need further observation.
ABSTRACT
Objective To evaluate the diagnostic value of tracking movement of normal patellar using volume scan on sensation 320 CT. Method Data of dynamic scans of 30 knees was collected using the motor function of 320 CT and retrospectively analyzed. The data of movement of the patellorfemoral joint was obtained during flexion (from 0° to 120°) within 10-sec by 320 CT from all volunteers. The 3D coordinate of the center of patella was recorded to investigate the dispose relation of patellofemoral joint.Result With the knee angle changed from 0° to 90°, the patella moved rapidly along the Y-axis direction ( sagittal plane) down about (53.87 ± 0. 45 ) mm, and then entered the plateau phase with little change.When the knee flexion reached 10°-30° ,the patellar movement along the X-axis reached the largest range of (2. 31 ±0. 52)-(3.36 ± 0. 43 ) mm, and subsequently moved to the opposite lateral direction with the maximum about (8. 53 ± 0. 44 ) mm at 120°. In the Z axis, the track initially showed plateau, and then presented a rapidly downward trend after 30°. The patellar tracking is like an outward arc during the whole knee flexion. Conclusion The motor functional imaging of 320 CT can pinpoint the patelar tracking in a fast, painless way.
