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.

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

Objective To compare the efficiency of repairing perimembranous ventricular septal defect (VSD) with continuous stitching to that with interrupted stitching. Methods Of the 158 patients with perimembranous VSD ( 54% males) ,102 ( 65% ) patients underwent the repairing of continuous stitching (continuous group) ,and 56 patients underwent interrupted stitching (interrupted group). All the surgeries were performed under hypothermic cardiopulmonary bypass. Results The cardiopulmonary bypass time and aortic cross-clamp times were (31 ±14) mins and (18 ±12) mins in the continuous group, which was significantly less that those of (42 ± 16) mins and (25 ±11) mins in the interrupted group (t =4.49 and 3. 61 .respectively ,P <0. 05) . No case was died. The main complications involved temporary M atrioventricular block (AVB) of two cases (1 case in each group),which disappeared after 1 week. There were two remnants remaining leak (n =2) which was less than 3 mm and automatically cured after 3-6 months. Complete right bundle branch block(CRBBB) occurred in 3 cases in the continuous group and 6 cases in the interrupted group,of which 3 disappeared after 1 month and 2 disappeared after 12 months. The outcome was good in all cases after 1-3 years follow up. Conclusions Continuous stitching showed a shorter cardiopulmonary bypass and aortic cross-clamp times, and reduced the CRBBB.

Objective To investigate the effect of head-up tilt on cerebral blood flow velocity during general anesthesia in patients with diabetic neuropathy.Methods Sixty ASA Ⅰ - Ⅱ patients of both sexes aged 40-60 yr weighing 52-70 kg undergoing general anesthesia were divided into 3 groups according to diseases complicated with diabetes situation ( n =20 each):group Ⅰ normal control the patients did not have diabetes mellitus; group Ⅱ type Ⅱ diabetics without neuropathy and group Ⅲ Ⅱ diabetics with neuropathy.Anesthesia was induced with propofol 2 mg/kg,fentanyl 3 μg/kg and vecuronium 0.1 mg/kg and maintained with 1％ sevoflurane.The patients were intubated and mechanically ventilated.PErCO2 was maintained at 35-45 mm Hg.Transcranial doppler (TCD)was used to measure middle cerebral artery blood flow velocity (MBFV).MAP and MBFV were measured and recorded in supine position (baseline) and at 1.5,3.5 and 5.5 min of 45° head-up tilt.Results The 3 groups were comparable with respect to age,body weight,height and M/F sex ratio.MAP and MBFV significantly decreased at 45° head-up tilt as compared with the baseline in all the 3 groups.There was no significant difference in MAP and MBFV among the 3 groups.Conclusion Cerebral blood flow velocity decreases when the patients are tilted 45° head-up during general anesthesia in both diabetics with and without neuropathy,but there is no significant difference between the 2 groups.

Currently,the diagnosis of malignant pheochromocytoma still faces a big challenge.Neither biochemical nor histological features can be reliably used to distinguish malignancy from benign tumors.Numerous efforts have been applied to identify novel molecular markers to predict malignancy.

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.

Objective To investigate the clinical value of anti-nuclear antibody(ANA) and anti-nuclear antibody spectrum(ANAs) detection.Methods A total of 2 325 patients with or suspected with autoimmune diseases(AID) were enrolled and detected for ANA and ANAs by using indirect immunofluorescence assay(IIF) and linear immunoblot assay(LIA) respectively.All detected results were analyzed.Results Among 2 325 patients,896 cases(38.54%) were positive with ANA,with positive rate of 45.46% in female patients,which was higher than the 18.46% of male patients(P<0.05),and the common fluorescence patterns were nuclear particle pattern,nuclear homogeneous pattern and the nucleolus pattern.816 cases(35.10%) were positive with ANAs,and the positive rates of anti-Sjogren's syndrome(SS)-B antibody,anti Ro-52 antibody and anti SS-A antibody were relatively higher.The consistency rate of the two methods was 91.66%.Conclusion ANA and ANAs detection could be with certain correlation,but might be not completely consistent,detection could improve the detection rate and reduce the missed detection rate.
