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 express and preliminary identify scavenger receptor B2 (SCARB2)protein.Methods SCARB2 cDNA was amplified by reverse transcription-polymerase chain reaction (RT-PCR)from mRNA extracted from RD cells,and cloned into pMD19-T vector.Expression vector pET28a(+)/SCARB2 was constructed,and SCARB2 protein was expressed in prokaryotic ex-pression system.Obtained recombinant proteins were identified by detection of Western blot using His labeled monoclonal antibody.Results Recombinant SCARB2 proteins,expressed by induction of isopropy-β-D-thiogalactoside (IPTG),were success-fully purified and specifically recognized by His labeled monoclonal antibody.Conclusion SCARB2 proteins could be expressed and identified successfully,which could provide reference for researching mechanism of enterovirus type 71 (EV71)and scavenger re-ceptor protein,and for preparation of SCARB2 monoclonal antibodies.

Seventy C57BL/6 mice were divided into control group,lard group,lard transferred into safflower oil group,and safflower oil group.After 20 weeks,the white adipose tissues were taken to analyse the gene differentiational expression prolife.The results showed that body weight,blood glucose and lipids,and insulin levels in lard group were higher than those in control group( all P＜0.05 ),which were decreased after lard was transferred into safflower oil for 10 weeks( all P＜0.05 ).Safflower oil regulated some of the orexigenic genes,anorectic genes,and the genes involved in energy expenditure in adipose tissues such as opioid receptor,glucagon,and PPARα.

Dystonia is a syndrome which is characterized by sustained muscle contractions, producing twisting, repetitive, and patterned movements, or abnormal postures. According to genetic basis, dystonia is classified into 13 subtypes. We mainly discussed two subtypes, DYT1 and DYT5, in this review. Early-onset primary dystonia is caused by the mutation of DYT1 gene, which leads to TORSINA abnormal. GTP cyclohydrolase 1 (GTPCH1)-deficient DRD(DYT5) is caused by the mutations of GCH1 gene. By genetic testing, we can confirm clinical diagnosis of each subtype and develop prenatal diagnosis for it.
