BACKGROUND:Distal femur is a predilection site for primary bone tumors, most of which are treated with salvage treatment. There are many reports on the early-stage, mid-term and prognosis of the distal femur tumor-type artificial knee joint prosthesis, but reports on long-term function and prognosis are less.
OBJECTIVE:To study the long-term prognosis and limb function after treatment with rotating-hinge knee prosthesis.
METHODS:Thirty-four patients with distal femoral bone tumors admitted to the Department of Orthopedics, the First Affiliated Hospital of Anhui Medical University between January 2000 and June 2008 were retrospectively analyzed, including 19 males and 15 females. Al patients were subjected to rotating hinge knee prosthesis replacement.
RESULTS AND CONCLUSION:The mean fol ow-up period was 62.4 months (range 11 to 126 months). At the final of fol ow-up, 23 patients were event-free alive and 11 patients were dead. Seven of 23 survival patients suffered from prosthesis related complications, including four cases of prosthesis revision and three cases of amputation. The event-free survival rate of 23 patients undergoing replacement of domestic tumor prosthesis around the knee was 67.6%in 5 years. The mean functional score of affected limb was 19.30 (7 to 27 points):excellent in 6 cases, good in 16, fine in 5 and poor in 2. The excellent-good rate was 75.9%. The clinical outcomes suggested that the satisfactory limb function and survival rate could be achieved with the application of domestic tumor prosthesis replacement for treatment of malignant bone tumors around the knee.

BACKGROUND: The effectiveness and safety of traditional Chinese medicine treatment for chronic obstructive pulmonary disease (COPD) have been preliminarily approved by clinical practices.OBJECTIVE: To investigate the effects of Gubenkeli capsule on the protein expression of matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinase1 (TIMP-1) in lung tissue of COPD model rats.METHODS: A total of 50 Wistar rats were randomly divided into five groups with 10 rats in each group: normal control, model, prednisone, Gubenkeli capsule-low dose, and Gubenkeli capsule-high dose. COPD rat models were established in all rats with the exception of the normal control rats by smoking and intratracheal instillation of LPS. At 29 days after COPD induction, rats from the prednisone, Gubenkeli capsule-low dose, Gubenkeli capsule-high dose groups were intragastrically administered prednisone (1.04 mg/kg per day), Gubenkeli capsule (0.4, 0.94 g/kg per day), once a day, to observer rat general conditions. Protein expression of MMP-9 and TIMP-1 in the lung tissue was detected by immunohistochemical methods. RESULTS AND CONCLUSION: Protein expression of MMP-9 and TIMP-1 in the lung tissue of COPD rats was significantly increased (P < 0.05). After drug intervention, the general conditions of COPD rats were greatly improved, and protein expression of MMP-9 and TIMP-1 in the lung tissue was decreased. Prednisone yields the strongest effects, followed by high-dose Gubenkeli capsule and low-dose Gubenkeli capsule. These findings demonstrate that Gubenkeli capsule alleviates the clinical manifestations of COPD model rats, improve airway remodeling, and correct the imbalance between prolease and antiprotease in a dose-response manner.

Objective To evaluate multi-slice spiral CT venography (MSCTV) and digital subtraction venography (DSV) in diagnosing iliac vein compression syndrome (IVCS) and secondary thrombosis. Methods The imaging materials, including MSCTV and DSV performed before and after the thrombolysis therapy, of 38 patients with clinically-suspected IVCS were collected. The inner diameters of the compressed iliac veins were measured on MSCTV images and the compression ratio was calculated. Usingχ2 test, the detection rates of IVCS by MSCTV and DSV were compared. Results Of 38 patients, IVCS was detected by MSCTV in 29, by pretreatment DSV in 20 and by post-treatment DSV in 29. The difference in the detection rate of IVCS between MSCTV and pre-treatment DSV was statistically significant (χ2=4.65, 0.01
0.05). Conclusion For the diagnosis of IVCS, MSCTV is superior to pre-treatment DSV in the diagnostic accuracy of iliac vein compression syndrome. Therefore, MSCTV should be used as the preferred method of examination.(J Intervent Radiol, 2015, 24:301-305)
