Fourteen patients with vascular stenosis in carotid artery system were treated using angioplasty and stenting.The stenosis was located at bifurcation in 6 cases, intracranial internal carotid artery in 3, horizontal segment of middle cerebral artery in 3, and original segment of common carotid artery in 2. Depending on the long and degree of stenosis,different types of SMART stents and Biodivysio stents were selected for the endovascular angioplasty via the femoral approach in 13 cases. Balloon dilatation angioplasty was performed in one case. All the angioplasties in 14 cases were successfal. Different improvement was achieved in patients with neurological defects and no stroke was found in NIHSS after endovascular angioplasty. Following up 3 to 14 months, there was no TIA and other ischemic neurological defect. The primary results of our group showed that endovascular angioplasty and stenting are effective and safe for carotid stenosis. It should be one of the favorable choices for the treatment of vascular stenosis in catotid artery system.

Objective:To study the mechanisms of neutrophil elastase (NE) induced expression of respiratory mucin MUC5AC. Methods:Using gene recombination techniques,four luciferase reporter gene plasmids containing different length of human MUC5AC gene promoter were constructed.Site-directed mutagenesis technique was used to establish mutants of Sp-l and NF-?B site in MUC5AC gene promoter; the relative luciferase activities were detected in the transfected human pulmonary A549 cells. Results:Series of luciferase reporter gene containing different sequences of human MUC5AC promotor were constructed successfully.NE could increase the expression of luciferase reporter gene plasmid containing -1300bp,-689bp and-324bp version of MUC5AC promoter in the transfected A549 cells (P

OBJECTIVETo compare the cleaning effect of automatic cleaning machine and manual cleaning on coupling type surgical instruments.

METHODSA total of 32 cleaned medical instruments were randomly sampled from medical institutions in Putuo District medical institutions disinfection supply center. Hygiena System SUREII ATP was used to monitor the ATP value, and the cleaning effect was evaluated.

RESULTSThe surface ATP values of the medical instrument of manual cleaning were higher than that of the automatic cleaning machine.

CONCLUSIONCoupling type surgical instruments has better cleaning effect of automatic cleaning machine before disinfection, the application is recommended.

Objective To investigate the effects of arsenic trioxide(As2O3)combined with ascorbic acid(AA) on the apoptosis and differentiation of myelocytic leukaemia cells.Methods The acute promyelecytic leukaemia cell lines (NB4 and MR2)and erythroleukemia cell line(KS62)were cultured in vitro.Grouping wasbased on different concentration of As2O3(0,0.1,0.2,0.5,1.0 μmol/L),which WaS used a8 control groups.Then,AA(113.0μmol/)was added into each group.Cell morphologic changes of cell lines NB4,MR2 and K562 were observed under light microscope;The apoptosis symbols [Annexin V(+)/PI(-),Annexin V(+)/PI(+)]and differentiation symbols(CD11b and CD33)were detected by flow cytometry 96 hours later.Results

Objective To discuss the image characters and the technical manipulation of endovascular embolization for cerebral AVM with bleeding. Methods The cerebral AVMs with bleeding in 56 cases were confirmed by CT, MRI, and whole cerebral DSA. Depended on the nidus of AVM, the superselective endovascular embolization with NBCA or embolization combined with radiological surgery was chosen. Results The nidus was eliminated for 100% in 36 cases after embolization for 1 to 3 processes. The rebleeding was found in 2 cases with new growth and survival aneurysm in nidus during the follow-up period and treatment with X-knife, and was cured by the second embolization. Conclusion The main causes of AVM bleeding included aneurysm and aneurysm-like dilation beside and located at the nidus, fine draining veins, and growth in the ventricles. To prevent the brain from bleeding, it is favourable to eliminate the aneurysm in AVM during embolization.

0bjective To observe the different brain activation of acupuncture and electroacupuncture on healthy subjects and healthy subjects.Methods The different brain activation involved in heroin addiction between healthy subjects and addicts was detected by fMRI.Acupuncture point used in present study Was Zusanli (ST 36).Results Different brain activations between healthy subjects and addicts during electroacupuncture were hypothalamus(X0,Y2,Z9,t=7.36,P<0.01),anterior cingulate(X5,Y49,Z8,t=4.11,P<0.01),tempo-ral gyrus(X61,Y12,Z8,t=3.05,P<0.01).The difference of activated regions during conventional acupuncture between healthy subjects and heroin addicts was thalamus(X2,Y16,Z12,t=2.87,P<0.01),parahippocampus (X17,Y52,Z3,t=3.14,P<0.01),and hypothalamus(X0,Y2,Z9,t=6.98,P<0.01).Conclusion Regions with significant activation detected by fMRI are different during acupuncture in heroin addicts and in the healthy subjects.Notably,the hypothalamus activation is more robust in the addicts than in the healthy subjects during ac-upuncture stimulation.
