Objective To explore the conventional MRI,diffusion-weighted imaging (DWI)characteristics and the pathological basis of angiomatous meningioma.Methods The conventional MRI,DWI and pathological manifestations of 7 cases with angioma-tous meningioma confirmed by surgery and pathology were analyzed retrospectively.The apparent diffusion coefficient (ADC)value of the tumors and contralateral normal brain parenchyma were measured and compared with each other.Results Among the 7 ca-ses,5 cases were in the convexity of brain (4 cases in the frontal part and 1 case in the parietal part),and 2 cases in the parasella. 6 cases showed hypointense on T1 WI and hyperintense on T2 WI,and 1 case showed isointense on both T1 WI and T2 WI.The necro-sis within the tumor was seen in 2 cases.The flowing void phenomenon was seen in 6 cases.The significant peritumoral edema was seen in 5 cases on FLAIR.Significant enhancement on contrast-enhanced T1 WI was seen in all the cases.The average ADC value of the tumors (1.35×10 -3 mm2/s)was significently higher than that of the contralateral normal parenchyma (0.92 × 10 -3 mm2/s) (t=7.21,P <0.01).Mature vessel component was seen on pathological section in all the cases.For immunohistochemically analy-sis,the expression of vimentin (Vim)was positive in 6 cases and scattered positive in 1 case.The expression of epithelial membrane antigen (EMA)was positive in all the cases.Conclusion The MRI features of angiomatous meningioma are closely correlated with rich blood vessels.The ADC value of the tumor is higher than that of the contralateral parenchyma,which is helpful for the diagno-sis.

Objective To research and compare the effectiveness distinction between applying exclusive salcatonin and combining salcatonin and Xianling Gubao to treat osteoporotic pain patients.Methods 84 cases of osteoporotic pain patients in our hospital from Feb.2013 to Feb.2014 were selected and divided into two groups.Patients in treatment group were received combination of salcatonin and Xianling Gubao treatment.Patients in control group received salcatonin treatment only.To apply VAS judge the pain degree of patients.The clinical performance and results were observed and recorded.The degree of satisfaction of patients was surveyed through questionnaire.Results The VAS of patients in treatment group was (2.17 ±1.02), while it was (4.26 ±1.37)in control group.There were 15 cases of excellent,and 23 cases of efficacious in treatment group and the total effective rate was 90.48%.There were 10 cases of excellent,and 19 cases of efficacious in control group and the total effective rate was 60.95%.The degree of satisfaction of patients in treatment group was 95.24%,while it was 71.43% in control group.Conclusion Combining salcatonin and Xianling Gubao has better clinical effect than applying exclusive salcatonin in treatment of patients with osteoporotic pain.The combination of them could quicken the speed of recovery and increase the degree of satisfaction of patients.

BACKGROUND:Ilizarov technique is an effective treatment method which can solve various complications that occurred in the process of treatment, especial y for the treatment of nonunion associated with soft tissue defects or severe infection. OBJECTIVE:To review the research progress of nonunion treatment with the Ilizarov technique. METHODS:A computer-based search was performed on the CNKI database and PubMed database from January 1992 to April 2013 for the articles related to the Ilizarov technology for the treatment of nonunion. The key words of“nonunion, external fixator, Ilizarov”in English and“nonunion, fracture nonunion, external fixation, Ilizarov”in Chinese were used to search the articles in the title and the abstract. Final y, a total of 37 articles were included to review. RESULTS AND CONCLUSION:Ilizarov technique is an effective method to treat limbs nonunion with the infection and severe bone defect. It has become an international y recognized gold standard. Due to the firmly fixation of the Ilizarov ring external fixator, it can not only eliminate the shear force and rotation stress, thus playing a role of stretch tension and compression, but also has the cyclical micro-axialmotion characteristic during weight-bearing walking which can better promote bone union. Based on the reviews of the research progress of Ilizarov technique in the treatment of nonunion in recent years, we further investigate the advantages and methods of Ilizarov technique in the treatment of limbs nonunion. The clinical application of the method should fol ow the individual principle, and then choose the best and suitable method based on the analysis of advantages and disadvantages about the patient’s condition.

Objective: Through comparing the hospitalization costs of total knee replacement (TKR) in People’s Hospital of Peking University in 2005 and 2010, to investigate the changing status of hospitalization costs on this operation and the impact of clinical pathway ( CP ) on controlling the hospitalization costs during 5 years , and provide references for controlling medical treatment cost reasonably. Methods: The patients are grouped into undergoing unilateral and bilateral TKR. The total hospitalization cost and cost of each category during 5 years are compared, and SAS 9.2 statistic software is applied to deal the data. Results: Compared with 2005, the total cost for TKR in 2010 decreased. All the charging items decreased, except implant material increased, especially the cost of surgery, hospital room, nursing and pharmacy. Specific to one knee replacement group and both knees replacement, the changing trend of cost is coincident with the total cost. Conclusion: The total cost for TKR in 2010 was lower than that of 2005, which might be the result of adopting CP since 2010. Nevertheless, the implant material cost accounted large proportion of hospitalization cost in 2010, and it has obvious increasing trend compared to 2005. This result is related the increasing application of the new edition of Artificial knee joint prosthesis. Controlling implant material cost is the effective method of decreasing medical costs for TKR.
