Objective To establish virtual three-dimensional instrument and cerebral aneurysm models by using three-dimensional moulding software,and to explore the effect of the models in interventional preoperative simulation.Methods The virtual individual models including cerebral arteries and aneurysms were established by using the three-dimensional moulding software of 3D Studio MAX R3 based on standard virtual cerebral aneurysm models and individual DSA image.The virtual catheter,guide wire,stent and coil were also established.The study of interventional preoperative simulation was run in personal computer,and included 3 clinical cases.Results The simulation results of the working angle and the moulding angle of the head of catheter and guide wire in 3 cases were identical with that of operation results. The simulation results of the requirement of number and size of coil in 1 case of anterior communicating aneurysm and 1 case of posterior communicating aneurysm were identical with that of operation results.The simulation results of coil for aneurysmal shape in 1 case of giant internal carotid artery aneurysm were more than 2 three-dimensional coils with size of 3mm?3 cm from the operation results,and the position of the second coil in aneurysmal neck was adjusted according to the results of real-time simulation.The results of retrospective simulation of operation procedure indicated that the simulation methods for regular and small aneurysms could become a routine simulation means but more simulation experience was needed to build up for the giant aneurysms.Conclusions The virtual three-dimensional instrument and cerebral aneurysm models established by the general software provided a new study method for neuro-interventional preoperative simulation,and it played an important guidance role in developing neuro- interventional operation.

In vivo fast cyclic voltammetry (FCV) was used to investigate dopamine (DA) release from amygdala (Amy) of female rats in different phases of estrus cycle, ovaricectomized (OVX) rats and male rats. Tyrosine hydroxylase (TH) immunohistochemistry was employed to measure the numbers of immunoreactive neurons in ventral tegmental area (VTA) of midbrain in the rats. We also observed the effect of intracerebroventricular injection of phytoestrogen-soy isoflavones on DA release from the Amy. The results are as follows: DA release from the Amy of proestrus female rats was apparently higher than that in estrus, metaestrus, diestrus female rats and OVX rats. Amy DA release and the numbers of the TH immunoreactive neurons in VTA showed a significant sex difference. DA release from Amy of female and OVX rats increased significantly within 5 min after i.c.v injection of soy isoflavones, which elicited no effects in male rats. The above-mentioned results suggest that endogenous estrogen may play an important role in regulating the activity of DA neurons in mid-limbic systems, and that soy isoflavones exert an estrogen-like effect on the dopaminergic systems in the Amy.

Objective To investigate the expression of lipid rafts (LRs) and actin cytoskeleton (F-actin) in the peripheral blood B lymphocytes of patients with systemic lupus erythematosus (SLE).Methods Peripheral blood mononuclear cells (PBMCs) were separated by Ficoll-Hypaque.B lymphocytes were isolated by positive selection from PBMCs.Membrane staining for LRs was achieved with FITC-conjugated cholera toxin B (CTB).The level and distribution of LRs were studied by flow cytometry and confocal microscopy.Staining for F-actin was carried out with Rhodamine phalloidin.The expression of F-actin was analyzed by confocal microscopy.In an in vitro examination,the effect of Leflunomide on lipid rafts in B lymphocytes from SLE was analyzed.Disease carried out was measured using the SLE disease activity index (SLEDAI).Analysis of the enumerical data was performed using ANOVA or paired-samples t test.Correlation was examined by Pearson's rank correlation test.Results The number of CTB-binding lipid rafts in B cell from active SLE patients or from SLE patients in disease remission.who were treated with immunosuppressive drugs was higher than B cells from healthy controls [(59+4)％,(51±5)％,(33±4)％,F=9.21,P=0.001].Confocal microscopy revealed that in B cell from healthy controls,lipid raft was found to be small and uniformly distributed on the plasma membrane.F-actin was found mainly in the cortical region of the cells.This pattern was different from the pattern seen in B cells from patients with SLE,which presented with stronger staining and irregular large clustering of LRs,with a decrease in F-actin levels.In addition,the number of CTB-binding LRs in B cells from the active SLE patients was correlated significantly with the SLEDAI score (r=0.632,P=0.028).Furthermore,thein vitro results showed that leflunomide treatment reduced the number of CTB-binding LRs in B cell from SLE patients [(48±5)％ vs (39±5)％,t=2.29,P=0.048].Conclusion The altered expression of Lipid raft and F-actin can been seen in B lymphocytes in SLE,and modulation of LRs and F-actin expression may be a potential approach in the treatment of SLE.

Objective To explore the relativity of preoperative health status and perioperative com-plication incidence of aged patients. Methods The chnical data of 3108 old aged people (60 and above 60 years old)who were operated from January 2006 to November 2007 was retrospectively analysed. General e-valuated preoperative health status, and summarized perioperative complication incidence. Results Before operation, 68.7% patients had one or more coexist disease, 41.1% patients had two or more coexist dis-eases, 38.7% had three coexist diseases in the meantime. After operation,one or more complications oc-curred in 21.4% (666/3108)patients, 2.8% (88/3108) patients died because of heart,brain,lung, kidney function failure. Conclusions Aged patients have more coexist diseases, the complications and death rates are higher than those in younger patients. The complications are correlated with preoperative health status and coexist diseases. Some factors could influence the patients rehabilitation,such as heart,brain,lung, kidney function, water-electrolyte balance and blood glucose change.

Objective To investigate prospectively the diagnostic significance of ulnar/median nerve amplitude ratio in motor neuron disorders.Methods Patients referral to our department between May 2009 and February 2012,due to muscle weakness,inflexible,cramps and atrophy,were consecutively enrolled.Conventional nerve conduction studies of 4 extremities (using surface electrodes) and needle electromyography were performed in all patients with fixed examiner.The compound muscle action potentials (CMAP) were recorded from abductor digiti minimi (ADM) and abductor pollicis brevis (APB) with stimulation of ulnar and median nerve at wrist,respectively.Moreover,the ratio of CMAP amplitude between ADM and APB (ADM/APB) was calculated in the patients who met the diagnostic criteria for definite amyotrophic lateral sclerosis (ALS) and Hirayama disease (HD).The patients with Guillain-Barré syndrome (GBS) and other popyneuropathies (PN) were served as case-controls,and 34 healthy volunteers (aged (45.7 ± 16.3) years) as normal-controls.Results (1) There were 78 cases with ALS,25 HD,51 GBS and 140 other PN,with the mean age(years) of 54.7 ± 11.6,17.6 ± 2.2,41.3 ± 18.4 and 57.1 ± 14.3,respectively.(2) ADM/APB in the ALS subgroup was 2.28 ±2.87 (0.12-22.38),HD0.66±0.36 (0.05-1.34),GBS 1.42 ± 1.33 (0.25-9.85),other PN 1.36 ± 1.48 (0.08-14.44) and normal-controls 1.07 ± 0.28 (0.61-1.64,F =6.872,P =0.000),respectively.(3) The areas under receiver operator characteristic curve in patients with ALS was 0.830 (s-x =0.039) and HD 0.691 (sx =0.039,P =0.000) ; the diagnostic sensitivity and specificity for ALS patients were 36.7％ and 93.3％,respectively,with cutoff value of ADM/APB =2; and the diagnostic sensitivity and specificity for HD patients were 53.6％ and 89.0％,respectively,with cutoff value of ADM/APB =0.7.Conclusions The ulnar/median CMAP amplitude ratio increases in ALS,but decreases in HD,which may be served as a relatively specific electrophysiological index.ADM/APB amplitude ratio ＞ 2.0 is suggested to be a diagnostic parameter for ALS and ＜ 0.7 for HD.

[ABSTRACT]OBJECTIVETo investigate the morbidity rate and the epidemiological characteristics of snoring among the elderly in Yangpu District of Shanghai City.METHODSOne thousand six hundred and thirty persons(≥60 years) were investigated through questionnaires in Yangpu District of Shanghai City by a method of cluster sampling.The prevalence and risk factors of snoring were estimated. The relationship between snoring and the common clinical complications was observed by correlation factor analysis.RESULTS1630 questionnaires were provided, among which 1489 questionnaires(91.35%) were effective for evaluation.Of 1489 subjects, 213(14.3%) subjects had habitual snoring. Multivariate analysis revealed that obesity as a significant risk factor of snoring. The prevalence rate of snoring in the elderly with hypertension and poor quality of sleep was higher than that in the normal elderly.CONCLUSIONThe prevalence of snoring in the elder persons (≥60 years) in Yangpu District of Shanghai City is high. Obesity is a significant risk factor of snoring. The main clinical presentations of snoring in the elderly are atypical by the performance of poor sleep quality and the complication of hypertension.

Objective To explore the unique relationship between Willis circle and cerebral watershed infarction in a Chinese population. Methods A retrospective analysis of cerebral CT angiography was conducted in 471 non-cere?bral watershed infarctions and 93 MRI-diagnosed cerebral watershed infarctions (CWI)(including External CWI and In?ternal CWI)in Department of Neurology of our hospital and compare the related variations and types of Willis circle be?tween these groups. Results Compared with non-cerebral watershed infarctions, the prevalence of Uni-FTP (short for“fetal type of the Posterior cerebral artery”) in E-CWI (36.4%, P<0.05) and Bi-FTP in I-CWI (0%, P<0.05) was signifi?cantly higher in cerebral watershed infarctions. Conclusion FTP is probably an unique risk factor in Chinese patients with CWI.
