80 male Wistar mice were randomly divided into 8 groups. The effects of the big black Ant preparations (alias Xuanju ) obtained in different ways and their compound preparations in different dosages on the amount of RNA and DNA in the testes of mice were observed. After administration of the preparations for 21 days, the mice were decapitated and the testes were excised and weighed. The RNA and DNA in the testes were isolated andpurified with the method of SDS- phenol and their amounts were measured with UV-VIS spectrophotometry. The results showed that the mean testes weight in the experimental groups was significantly higher than that in the control group (P

Deep venous thrombosis in the lower extremities is a very common disease clinically and can greatly affect people in their work and life without proper treatment promptly.The author reviewed the etiology,diagnosis,preventive measures and the synthetic therapies for dealing the deep venous thrombosis in the lower extremities,especially concerning the interventional radiology.

Based on ESI web of science,the article analyzed papers published by three Medical Schools from 2001 to 2012 in terms of volume of publication,cited times,discipline distribution,au thors and cooperation,and determined each factor's impact on research output and performance.Sug gestions and advice were given to enhance the overall basic medical science research level.

Objective To evaluate multi-slice spiral CT (MSCT) various postprocessing technique in diagnosing thoracolumbar burst fracture.Methods MSCT scaning was performed in 36 patients with 42 thoracolumbar vertebrae burst fracture altogether. The raw data of allthese cases were processed respectively by four kinds of image reconstruction, including multiple planar reconstruction (MPR), maximumintensity projection (MIP), surface shaded display (SSD) and virtual endoscope (VE), and the CT findings were compared with pathological results.Results The diagnosis was based on a combination of MPR with conventional axial scans which could display two dimensional images well. MIP could only show the fracture of lamina of vertebral arch and was superior to other techniques in displaying the whole figure. On the basis of imaging characteristics the fracture of lamina of vertebral arch was divided into 5 types:vertical, transversal, “7”-graphemic or reverse“7”-graphemic ,“S” and displaced. SSD fully displayed three dimensional surface of the fractured vertebral body as well as the severity of compressed vertebrae. VE could show displaced vertebrae and also the severity of narrow spinal canal.Conclusion Based on two dimensional images and combined with three dimensional images, MSCT can comprehensively show the thoracolumbar burst fracture. Several methods should be applied jointly.

The clinical features of the emergent and seriously ill patients are summarized,the mechanisms,features and fields of applications of current commonly-used emergency transporting ventilators are studied and analyzed,the advantages and disadvantages of various types of emergency transporting ventilators in the clinical application of emergency transporting are made comparisons. The technical development of domestic and foreign emergency transport ventilators is introduced,which points out that mini and multi-functional ventilators are the inevitable trend of emergency transporting ventilators and should be used in correspondence with specific clinical circumstances.

s Objective To select the appropriate upgrading solutions for hospital department-level Mini-PCAS system. Methods Based on the analysis of the inadequacies of the GE-PACS/RIS system in hospital,it was proposed that hospital should upgrade the existing system from both hardware and software. Results The system not only enhanced the working efficiency but also enhanced and expanded the functions in management in some image department. Conclusion With the advantages of foreign PACS and domestic RIS system,the system is an appropriate solution.

The determination of fraxetin A and fraxetin B in Cortex Fraxini have been carried out by HPLC on the stationary phase:octodecyl-silicohydride bonded silica gel column. The mobile phase was methanol-water(24:76). The detection wavelength was at 348nm. There was a good linear relationship in a concentration range of 16?g/ml~176?g/ml. The correlation coefficients were 0. 9995 and 0. 9994,respectively. The recovery of the added sample were 99. 1 ?1. 5% (n=5) for fraxetin A and 99.8?2. 5%(n=5) for fraxetin B. This method showed 0. 8% of within-day accuracy and 6. 2% of between-day accuracy,involving the advantages of simplicity,quickness and accuracy.

Objective To evaluate transurethral ultrasonic scanning in the diagnosis and staging of bladder tumor. Methods Form 1996 to 2000 transurethral ultrasonography(TUUS) was carried out for 70 cases of bladder cancer and the findings were compared with cystoscopy,transabdominal ultrasonography(TAUS),CT,MRI and pathological studies. Results The diagnosis rate of TUUS has been 99.1% being better than cystoscopy and TAUS.The accurate staging rate was 100.0% in stage T 1 tumors, 95.8% in stage T 2,82.4% in stage T 3 and 55.6% in stage T 4. Conclusions TUUS can clearly reveal the depth of tumor infiltration and therefore is an important method for the diagnosis and staging of early bladder tumor.

OBJECTIVE:To provide into the regularity of anaphylactic shock induced by fosfomycin injection.METHODS:The reports of fosfomycin-induced anaphylactic shock from 1994 to 2004 were retrieved and analyzed.RESULTS:36 cases of anaphylactic shock were publicly reported in these 10 years,among which there were 3 cases of death.CONCLUSION:Fosfomycin may induce anaphylactic shock,which should arouse more attention in clinic.
