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

Acute and chronic infection of sinus could expand to orbital cavity. As the technique and equipment of endoscopic surgery are getting popular and renewal, endoscopic sinus surgery is being used widely and profoundly, which improves the surgical effect of nose and sinus diseases greatly. However, the complications are not decreased rather than traditional surgery. The rate of orbital complication is the highest of all endoscopic sinus surgery. This paper present a case report about orbital complication due to sinusitis or endoscopic sinus surgery and related literature were reviewed.

BACKGROUND: A left-to-right shunting animal model is needed to study chronic pulmonary vascular remodeling of congenital heart attachment disease in adult.OBJECTIVE: To observe the characteristics of chronic pulmonary arterial hypertension in rat models subjected to left-to-right shunting.DESIGN, TIME AND SETTING: Randomized controlled animal modeling observation was performed in Experimental Animal Center, Xinqiao Hospital, the Third Military Medical University of Chinese PLA from April 2008 to April 2009.MATERIALS: A total of 80 male inbred line healthy SD rats of specified-pathogens free class, 4 weeks old, weighing 95-110 g, were randomly assigned into control group (n=40) and shunt operation group (n=40). A shrinking polyethylene blood vessel connector (proximal part inner diameter was 0.6 mm and outer diameter was 0.8 mm, while distal part's was 0.8 mm and 1.0 mm, respectively, 1.6 mm long), was applied.METHODS: Shunt operation group underwent left-to-right shunting through right common carotid artery and external jugular vein connected by shrinking polyethylene blood vessel connector. Control group underwent sham operation. At 4, 8, 12 and 16 weeks postoperation, ten models were determined with a series in procedures: hemodynamics detection, pathological sample preparation, hematoxylin-eosin staining, imaging analysis and so on.MAIN OUTCOME MEASURES: Changes in right ventricular systolic pressure, right ventricular hypertrophy index of right ventricle to left ventricle plus interventricular septum, and relative medial wall thickness in moderate sized pulmonary arteries in rats of shunt group and control group.RESULTS: All animal were survived. The pulmonary blood flow in shunt group was significantly higher than control groups (P<0.01). Compared with control group, right ventricular systolic pressure elevated obviously and right ventricular hypertrophy index were significantly higher in shunt group at 12 and 16 weeks (P<0.01). Compared with control group, the relative medial wall thickness in pulmonary arteries also elevated obviously in shunt group at 12 and 16 weeks (P<0.01).CONCLUSION: Left-to-right continuous low-flow shunt in rats can induced right ventricle accommodated with the change of right ventricular systolic pressure and promote chronic pulmonary arterial remodeling continuously. The procedure of establishing left-to-right shunting models with common carotid artery and external jugular vein connection, is a stable tool for studying chronic pulmonary arterial hypertension induced by low flow.

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.

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.

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.
