Open surgery was the main treatment for abdominal aortic diseases in the past .However , with the development of endovascular instruments , endovascular repair technique has become the main option for abdominal aortic diseases .Unibody bifurcated stent-graft and modular bifurcated stent-graft are often used to treat abdominal aortic diseases .Unibody bifurcated stent-graft has its own features in endovascular repair of abdominal aortic diseases .We made a literature summary on application of unibody bifurcated stent-graft in abdominal aortic diseases .

Objective To study the regional homogeneity (ReHo) of default-mode network (DMN) in patients with minimal hepatic encephalopathy (MHE) with resting state fMRI.Methods Eighteen MHE patients and eighteen healthy controls (HC) underwent standard resting state fMRI scan.The resting state fMRI data were analyzed with the ReHo method to observe the changes of DMN in the patients in contrast to the controls.Results Compared to healthy controls,MHE patients showed lower ReHo in bilateral MPFC/anterior cingulate cortex(V=13.257 cm3;MNI coordinates=3,24,66;t=-3.493 7),bilateral precuneus/posterior cingulate cortex(V=4.752 cm3;MNI coordinates=9,-54,45;t=-2.634 1),while higher ReHe in right medial prefrontal cortex(V=5.049 cm3;MNI coordinates=21,63,6;t=4.017 5).Conclusion In MHE patients,there is abnormal neuron activation in the widespread DMN regions under resting state, which indicated abnormal spontaneous activity consistency within DMN and endogenous brain function injury in MHE patients.ReHo can be used to observe DMN changes in MHE patients.

Objective To observe effects of shuxuetong injection combined with edaravone injection on the neurological, sermn lipid, c-reactive protein and interleukin 6 Levels in serum in patients with acute cerebral infarction. Methods 100 patients with acute cerebral infarction were randomly recruited into a control group and a treatment group by means of random number table. The control group was treated with 30mg edaravone injection, which was added to 100 ml normal saline, twice a day, continuous therapy for 14 days, and the treatment group was treated with 6mg shuxuetong injection, which was added to 2S0 ml normal saline, once a day, continuous therapy for 14 days based on the control group. The neurological was observed, triglyceride (TG) , cholesterol (TO , low density lipoprotein cholesterol (LDL-C) , high density lipoprotein cholesterol (HDL-C) , c-reactive protein and interleukin 6 Levels in serum were detected before and after the treatment.Results Compared with the control group, neurological deficit score, c-reactive protein and interleukin 6 Levels in serum in the treatment group decreased significantly (χ2=4.351, 3.81, 3.617 respectively, P<0.05) .TG, TC, LDL-C in serum in the treatment group were lower than that of the control group (χ2=2.135,P<0.01; χ2=3.061, 3.655, P<0.05 ); HDL-C in serum was higher than that of the control group (χ2=2.762,P<0.01) . The total effective rate of the treatment group and the control group was 86.0% and 66.0% respectively, there was a significant difference (χ2=3.393, P<0.05) . Conclusion Shuxuetong injection combined with edaravone injection is better than edaravone injection to treat acute cerebral infarction.

Objective To assess the effect of nicotinic acid on hyperphosphatemia in maintenance hemodialysis (MHD) patients.Methods Twenty-six MHD patients with stable disease condition and hyperphosphatemia that could not be successfully controlled by conventional methods were selected.All patients were treated with oral nicotinic acid for 20 weeks.The changes of serum calcium,high sensitivity Creactive protein (hs-CRP),albumin (ALB),aspartate aminotransferase (AST),alanine aminotransferase (ALT),gamma-glutmyltransferase (GGT),total bilirubin (TBIL),derect bilirubin (DBIL),high density lipoprotein cholesferol (HDL-C),low density lipoprotein cholesferol (LDL-C),triacylglycerol (TG),total cholesterol (TC),intact parathyroid hormone,hemoglobin,platelet count,etc were observed before and after treatment.Results Two patients withdrew from this study because.of pruritus and diarrhea after two weeks of oral nicotinic acid.In 24 cases,compared with that before treatment,the serum phosphate,calcium-phosphorus product was decreased [(1.49 ± 0.19) mmol/L vs.(2.13 ± 0.16) mmol/L,(4.40 ± 0.49)mmol2/L2 vs.(5.45 ± 0.36) mmol2/L2] and HDL-C was increased [(1.45 ± 0.14) mmol/L vs.(1.18 ± 0.15)mmol/L] after treatment,and there was significant difference (P ＜ 0.05).There was no significant difference in the serum calcium,iPTH,LDL-C,TG,TC,ALB,AST,ALT,GGT,TBIL,DBIL,hs-CRP,platelet count,hemoglobin between before and after treatment (P ＞ 0.05).Conclusions Nicotinic acid is effective as all adjuvant measure in control of hyperphosphatemia in patients on MHD and can increase HDL-C.It provides a new approach for the treatment of hyperphosphatemia.

Objective To explore the health inspector effect on the score of hygienic degree of hostels. Methods Using the scale for hygienic degree of hostels, 38 health inspectors from 9 sections in the Bureau for Health Inspection and Supervision of Haidian District in Beijing, scored 621 hostels in the district. The multilevel statistics model has been used to analyze the health inspector effect, of which the index is intra-class correlation (ICC), in the double level model structured by hostels as the level 1 unit and inspectors as the level 2 unit, and in the triple level model structured by hostels as the level 1 unit, inspectors as the level 2 unit and the sections as the level 3 unit. Results In the double level model, ICC of the level 2 unit is 0.142 8. In the triple level model, ICC of the level 2 unit is 0.0000 and ICC of the level 3 unit is 0.154 1. Conclusion There is inspector effect influencing the score of hygienic degree. And the effect seems to be more similar in one section comparing with the other ones.

Objective To explore the basic health state of the hotels in Haidian District. Methods 736 hotels were chosen to investigate on the hygiene state, in Haidian District, Beijing, during Feb.-Jul., 2006, based on the tables for the hygienic quantified and classified management of hotel health supervision. Results The hygienic quantified and classified standard score of 736 hotels was 53.7?22.6, and the standard score of the common hotels, one or two stars hotels and three or more stars hotel were 50.9?21.5, 58.9?24.7, 76.4?17.1. 50 households (6.8%) within them were A degree, 144 households (19.6%) were B degreee, 121 households(16.4%) were C degree and 421 households(57.2%) were D degree. Conclusion The general hygienic state of the hotels should be paid more attention to. The hygienic state changes with the level of the hotels.

The specific binding capacity of androgen receptor (AR)and estrogen receptor (ER)in the peripheral lymphocytes was estimated by radioligand binding assay in 130 diabetic patients (type Ⅰ 18 cases and type Ⅱ 112 cases). Results were as follows:1)plasma estradiol (E2) of diabetic patients was significantly lower than that of the controls (P

Elderly agrypnia patients were given with different doses of melatonin. Patients′ falling a sleep time, coming into effect time, sleep lasting time and adverse effect of melatonin were observed to study the effect and safety of melatonin on elderly agrypnia patients. The results showed melatonin could effectively improve the agrypnia suffered by elderly patients. Patients′ falling a sleep time was shortened and sleep lasting time prolonged after taking melatonin. The effect of melatonin increased along with increase of its dose.There were no adverse effects observed. Our study indicates that melatonin has a good safety profile and significant effects on agrypnia suffered by elderly patients.

In order to detect and localize melatonin receptor and its mRNA expression in the human skin, human skin was obtained from healthy volunteers. Immunohistochemistry and RT-PCR were applied to detect MR in human skin and to identify its subcellular distribution. Electrophoresis of RT-PCR product showed positive band of mt 1 subtype in human skin. The subtype of MR, mt 1was present in the membrane, cytosol and nucleus of skin cells as shown by immunohistochemistry. It is suggested that skin is the target organ of melatonin.
