| 1 | A HEMODYNAMIC MODEL AND A MATHEMATICAL METHOD TO CALCULATE THE DYNAMICS INDEX FOR CEREBRAL CIRCULATION显示文摘The dynamics indexes,playing an important role in the cerebral circulation,will be changed significantly compared with their normal range in many cerebrovascular disease.The geometrical parameters of cerebrovascular may be detected by DSA or MRA scan,but the hemodynamic parameters,such as,blood flow,artery resistance and compliance must be calculated by building hemodynamics model. The cerebral circular system that has four entrances for blood flow(two carotid and two vertebral arteries)and three communicating arteries is much different from the systematic ststem which has only one entrance,ic.,the aortic.The purpose of this study is to set up a hemodynamics model with lumped parameters to describe the cerebral circulation.From this model,we get its governing equations and present a new method to calculate the hemodynamics indexes in clinical application. | Ding Guang-hongDepartment of Applied Mechanics, Fudan University, Shanghai 200433, P.

| 2 | Expression of Pdx-1 in bone marrow mesenchymal stem cells promotes differentiation of islet-like cells in vitro显示文摘Bone marrow mesenchymal stem cells(BMSCs) have the ability of self-renewal and multi-directional differentiation.Recent reports showed that BMSCs could differentiate into endocrine cells of pancreas.However,the differentiation is not efficient enough to produce insulin-producing cells for the future therapeutic use.Pdx-1 is a crucial regulator for pancreatic development.Therefore we constructed a eukaryotic expression vector containing Pdx-1 to determine the effect of Pdx-1 ex-pression on differentiation of BMSCs in vitro.The results showed that BMSCs could self-assemble to form functional pancreatic islet-like structures after differentiation in vitro.The proportion of insu-lin-producing cells differentiated from Pdx-1+BMSCs was 28.23%±2.56%,higher than that from BMSCs transfected with vacant vector and Pdx-1-BMSCs(7.23%±1.56% and 4.08%±2.69% respec-tively) by flow cytometry.Immunocytochemical examination also testified the expression of multiple β-cells-specific genes such as insulin,glucagons,somatostatin in differentiated BMSCs.The results also revealed that the expressions of genes mentioned above in Pdx-1+BMSCs were higher than that in Pdx-1-BMSCs,which was confirmed by Western blotting analysis and RT-PCR.Glucose-induced insulin secretion from Pdx-1+BMSCs in 5mmol/L and 25mmol/L glocuse was(56.61±4.82) μU/mL and(115.29±2.56) μU/mL respectively,which were much higher than those from Pdx-1-BMSCs((25.53±6.49) μU/mL and(53.26±7.56) μU/mL respectively) .Grafted animals were able to maintain their body weight and survive for relatively longer periods of time than hyperglycemic sham-grafted controls,which demonstrated an overall beneficial effect of the grafted cells on the health of the animals.These findings thus suggested that exogenous expression of Pdx-1 should provide a promising approach for efficiently producing islet-like cells from BMSCs for the future therapeutic use in diabetic patients. | SUN Jiping1,YANG Yujia1,WANG Xiaoli1,SONG Jianhui1 & JIA Yanjie2 1.Department of Pediatrics,Xiang-Ya Hospital,Central-South University,Changsha 410008,China 2.Department of Neurology,the First Affiliated Hospital,Zhengzhou University,Zhengzhou 450052,China | 2006 | Science China(Life Sciences)2006，49，5： | 11 |
| 3 | Arsenic trioxide promotes mitochondrial DNA mutation and cell apoptosis in primary APL cells and NB4 cell lines显示文摘This study aimed to investigate the effects of arsenic trioxide(As2O3) on the mitochondrial DNA(mtDNA) of acute promyelocytic leukemia(APL) cells.The NB4 cell line was treated with 2.0 μmol/L As2O3 in vitro,and the primary APL cells were treated with 2.0 μmol/L As2O3 in vitro and 0.16 mg kg-1 d-1 As2O3 in vivo.The mitochondrial DNA of all the cells above was amplified by PCR,directly sequenced and analyzed by Sequence Navigatore and Factura software.The apoptosis rates were assayed by flow cytometry.Mitochondrial DNA mutation in the D-loop region was found in NB4 and APL cells before As2O3 use,but the mutation spots were remarkably increased after As2O3 treatment,which was positively correlated to the rates of cellular apoptosis,the correlation coefficient:rNB4-As2O3=0.973818,and rAPL-As2O3=0.934703.The mutation types include transition,transversion,codon insertion or deletion,and the mutation spots in all samples were not constant and regular.It is revealed that As2O3 aggravates mtDNA mutation in the D-loop region of acute promyelocytic leukemia cells both in vitro and in vivo.Mitochondrial DNA might be one of the targets of As2O3 in APL treatment. | MENG Ran1,ZHOU Jin2,SUI Meng3,LI ZhiYong4,FENG GuoSheng1 & YANG BaoFeng2 1 Division of Neurology,the Ninth Clinical Medical College of Beijing University(Shijitan Hospital),Beijing 100038,China 2 The First Hospital of Harbin Medical University,Harbin 150001,China 3 Management Information System,University of International Business and Economics,Beijing 100029,China 4 Department of Radiology,Cambridge University Hospitals NHS Foundation Trust Box 219 Level 5,Addenbrooke’s Hospital Cambridge CB2 0QQ,UK | 2010 | Science China(Life Sciences)2010，53，1： | 10 |

| 5 | Potential role of retina as a biomarker for progression of Parkinson's disease显示文摘Optical coherence tomography (OCT) noninvasively quantifies the thickness of the retinal nerve fiber layer (RNFL). OCT has been studied in several neuro-ophthalmic conditions, including Parkinson's disease (PD). Recent studies suggest that the quantitative analysis of RNFL can be precisely and noninvasively done by OCT scans and the results suggest that the thickness of RNFL is significantly decreased in patients with PD compared with age-matched controls and the foveal retinal thickness correlates with disease severity in PD. In this article, the application of OCT imaging of the retina in PD was reviewed. Literature survey of PubMed was carried out using the search terms of 'Optical Coherence Tomography' combined with 'Parkinson's Disease' and 'retinal nerve fiber layer' (without restriction to the year of publication). Some related articles were also included. The search was completed in Jul. 2011 and revised and updated as necessary. The aim of this article is to review the current literatures on the use of optical coherence tomography in patients affected by PD and to enhance its use in clinical practice in neuro-ophthalmology. | Tian Tian 1, Xiao-Hua Zhu 2, Yun-Hai Liu 1 1Department of Neurology, Xiangya Hospital, Central-South University, 87 Xiangya Road, Changsha 410008, Hunan Province, China 2Department of Ophthalmology, the Second Xiangya Hospital, Central-South University, 139 Renmin Middle Road, Changsha 410011, Hunan Province, China | 2011 | International Journal of Ophthalmology(English edition)2011，4，4： | 7 |
| 6 | Adenoviral-mediated Hath1-EGFP gene transfer into guinea pig cochlea through intact round window membrane显示文摘Objective To study expression of adenoviral-mediated Hath1-EGFP gene in the guinea pig cochlea after transfer through intact round window membrane(RWM), and to assess its effects on hearing. Methods Twenty adult guinea pigs were used, of which: 12 were surgically inoculated with Ad-Hath1-EGFP in the bony groove of round window niche, and 8 with artificial perilymph. Auditory brainstem response(ABR) thresholds were determined in all animals before and 5 days after surgery. On post-surgery day 5 and day 14, animals were sacrificed and whole mounts of cochlea and frozen sections were examined. Results ABR tests showed no significant change of hearing after the surgery. Strong fluorescence staining in the cochleae was seen in Ad-Hath1-EGFP groups. The highest levels of gene expression were seen in the post-surgery day 5 group with little decrease on post-surgery day 14.The contralateral cochlea and those in the control groups were free of fluorescence staining. Conclusion The transgenic Hath1-EGFP can be effectively delivered into the inner ear through intact RWM, in an atraumatic manner. | CHEN Wei1☆, HU Yin-yan1☆, YANG Shi-ming1*, GUO Wei1, SUN Jian-he1, HAN Dong-yi1, ZHAI Suo-qiang1, YANG Wei-yan1, David Z.Z.He2 1.

| 7 | Case Report:Lance-Adams syndrome:a report of two cases显示文摘Chronic post-hypoxic myoclonus, also known as Lance-Adams syndrome (LAS), is a rare complication of successful cardiopulmanry resuscitation often accompanied by action myoclonus and cerebellar ataxia. It is seen in patients who have un-dergone a cardiorespiratory arrest, regained consciousness afterwards, and then developed myoclonus days or weeks after the event. Worldwide, 122 cases have been reported in the literature so far, including 1 case of Chinese. Here we report 2 Chinese LAS patients with detailed neuroimagings. Cranial single photon emission computed tomography (SPECT) of patient 1, a 52-year-old woman, showed a mild hypoperfusion in her left temporal lobe, whereas patient 2, a 54-year-old woman, manifested a mild bilateral decrease of glucose metabolism in the frontal lobes and a mild to moderate decrease of the N-acetyl aspartate (NAA) peak in the bilateral hippocampi by cranial [18F]-fluorodeoxyglucose positron emission tomographic (PET) scan and cranial magnetic resonance spectroscopy (MRS), respectively. We also review the literature on the neuroimaging, pathogenesis, and treatment of LAS. | ZHANG Yan-xing1,2, LIU Jian-ren1, JIANG biao3, LIU Hui-qin1, DING Mei-ping1, SONG Shui-jiang1, ZHANG Bao-rong1, ZHANG Hong4, XU Bin5, CHEN Huai-hong6, WANG Zhong-jin1, HUANG Jian-zheng1 (1Department of Neurology, the Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou 310009, China) (2Department of Neurology, Shaoxing People’s Hospital, Shaoxing 312000, China) (3Department of Radiology, the Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou 310009, China) (4Department of Nuclear Medicine, the Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou 310009, China) (5Department of Neurology, the Second Affiliated Hospital, Zhejiang University of Traditional Chinese Medicine, Hangzhou 310005, China) (6Department of Geratology, the Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou 310009, China) | 2007 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2007，8，10： | 6 |
| 8 | Intrinsic control of axon regeneration显示文摘Spinal cord injury disrupts the connections between the brain and spinal cord, often resulting in the loss of sensory and motor function below the lesion site. The most important reason for such permanent functional deficits is the failure of injured axons to regenerate after injury. In principle, the functional recovery could be achieved by two forms of axonal regrowth: the regeneration of lesioned axons which will reconnect with their original targets and the sprouting of spared axons that form new circuits and compensate for the lost function. Our recent studies reveal the activity of the mammalian target of rapamycin (mTOR) pathway, a major regulator of new protein synthesis, as a critical determinant of axon regrowth in the adult retinal ganglion neurons[1]. In this review, I summarize current understanding of the cellular and molecular mechanisms that control the intrinsic regenerative ability of mature neurons. | Zhigang He F.M.

| 11 | Nonlinear analysis of the alcoholic's EEG显示文摘The nonlinear analysis is used to study the EEGs of the alcoholic and the control. Three kinds of expansions are discussed in order to get a more proper delay and then Liangyue Cao algorithm is implemented efficiently. Totally, there are 40 subjects involved in this study and the average values and the sample variances of D2s are computed. The results show that the average value of D2s of the alcoholic is larger than that of the control when the same electrode was used, which means that the brain dynamics of the alcoholic is more complex than that of the control. On the other hand, for most of the electrodes, the sample variance of D2s of the alcoholic is larger than that of the control, suggesting that the brain dynamics of the alcoholic is less steady. | SHAO Chenxi SHEN Linfeng WANG Xufa and YIN Shijie(1.

| 13 | Influence of mild hypothermia on vascular endothelial growth factor and infarct volume in brain tissues after cerebral ischemia in rats显示文摘BACKGROUND: It has been demonstrated that mild hypothermia has obvious protective effect on both whole and local cerebral ischemia. However, the definite mechanism is still unclear for the brain protection of mild hypothermia on cerebral edema, inhibiting inflammatory reaction, stabilizing blood brain barrier, etc. OBJECTIVE: To investigate the effect of mild hypothermia on the expression of vascular endothelial growth factor and the infarct volume after cerebral ischemia in rats, and analyze the brain protective mechanism of mild hypothermia. DESIGN: A randomized grouping and controlled animal trial. SETTING: Department of Neurology, People's Hospital of Yunyang Medical College. MATERIALS: Twenty adult male SD rats of clean degree, weighing (250±30) g, were provided by the animal experimental center, School of Medicine, Wuhan University. The kits for SP immunohistochemistry were purchased from Beijing Zhongshan Golden Bridge Biotechnology Co., Ltd. METHODS: The experiments were carried out in the laboratory of Department of Neurology, Renmen Hospital of Wuhan University from May to July 2005. ① The 20 rats were divided randomly into normal temperature group (n =10) and mild hypothermia group (n =10). Models of permanent middle cerebral artery occlusion were established with modified nylon suture embolization. The rats were assessed with the Longa standards: 0 point for without nerve dysfunction; 1 for mild neurological deficit (fore claws could no extend completely); 2 for moderate neurological deficit (circling towards the affected side); 3 for severe neurological deficit (tilting towards the affected side); 4 for coma and unconscious; 1-3 points represented that models were successfully established. The rats of the normal temperature group were fed at room temperature, and those in the mild hypothermia group were induced by hypothermia from 2 hours postoperatively, and the rectal temperature was kept at 34-35 ℃ for 72 hours. ② Measurement of infarct volume: All the rats were anesthetized by intraperitoneal injection overdose sodium pentobarbital 7 days postoperatively, and then the heads were cut down to harvest brain. The brain tissues were placed into -20 ℃ refrigerator for 20 minutes, coronal sections of 2 mm were prepared. The infarct sites were not stained, whereas normal brain tissues were stained as red. The infarct volumes were calculated by using MPLAS-500 multimedia color pathological image&word analytical system. ③ Counting positive cells of vascular endothelial growth factor protein: The brains were harvested by cutting heads, then coronal sections of 2 mm were prepared. Routine dehydration, hyalinization, wax immersion and embedding were performed, then the detected with SP immunohistochemistry, the kits were purchased from Beijing Zhongshan Golden Bridge Biotechnology Co., Ltd. The cells whose cytoplasm was yellow-brown were positive ones, a single sample as a unit, peri-ischemic site and ischemic core were selected, and the corresponding sites in controlateral hemisphere were taken as controls. Five visual fields were selected from each site to be observed under microscope, the cells were counted, and the average number of positive cells was calculated in each group. The numbers of positive cells were determined with the image analytical apparatus. MAIN OUTCOME MEASURES: Number of the positive cells of vascular endothelial growth factor protein; Infarct volume of rat brain tissue. RESULTS: All the 20 rats were involved in the analysis of results. ① Number of positive cells of vascular endothelial growth factor protein in brain tissue: It was obviously lower in the mild hypothermia group than in the normal temperature group [(24.02±5.05), (36.07±2.69) cells/high power visual field, P < 0.01]. ② Comparison of infarct volume of brain tissue: After MCAO, it was obviously smaller in the mild hypothermia group than in the normal temperature group [(153.25±23.14), (253.45±36.21) mm3, P < 0.01]. CONCLUSION: Mild hypothermia can inhibit the expression of vascular endothelial growth factor and decrease the volume of cerebral infarction. The inhibition of mild hypothermia on the expression of vascular endothelial growth factor may be one of the brain protective mechanisms. | Fei Ye1, Gangming Xi1, Biyong Qin1, Shifeng Wang1, Chengyan Li2 1Department of Neurology, People’s Hospital of Yunyang Medical College, Shiyan 442000, Hubei Province, China 2Department of Neurology, Renmin Hospital of Wuhan University, Wuhan 430060, Hubei Province, China | 2006 | Neural Regeneration Research2006，1，9： | 2 |
| 14 | Angioplasty with Stent for Symptomatic Intracranial Stenosis Trial I (ASSIT-Ⅰ) Study显示文摘Background and Purpose Annual stroke rates might be as high as 10% to 24% in patients with symptomatic intracranial stenosis on best medical therapy. Angioplasty with stent for symptomatic intracranial stenosis trial Ⅰ (ASSIST-Ⅰ) was a prospective and nonrandomized feasibility and safety study to evaluate the APOLLO Stent System for treatment of symptomatic intracranial artery stenosis, and prepare for ASSIST Ⅱ-a prospective, multicenter,and randomized controlled-study. The APOLLO stent delivery system (MicroPort Medical [Shanghai] Limited Co.), specifically designed for intracranial artery stenosis, consists of a stent and a balloon and a rapid-exchange delivery catheter. The stent is made of 316L stainless steel, with diameters of 2.0 to 4.0 mm and length of 8 mm or 13 mm. Only two links connect the rings of 1 mm in length, rendering the stent a good flexibility enough to navigate tortuous intracranial vessels. The nominated pressure of the stent is designed at 6 atm to reduce the risk of occlusion to side branches and perforators and rupture and dissection of target vessel. The crimping technique is applied in this system, insuring a compact ability of stent so wonderful that the struts of stent do not lift when the stent negotiates a turn, which lessen the likelihood of vessel wall injury and stent migrating. Materials and methods Thirty-four patients with 35 symptomatic intracranial stenoses of ≥50%, which resulted in transient ischemic attacks (TIAs [23 lesions /22 patients]) and minor stroke (7 lesions/7 patents), and both TIAs and stroke (5 lesions/ 5 patients), and with 1 asymptomatic severe stenosis, were enrolled in ASSIST-Ⅰ from December 10, 2003 to August 12, 2004. Their age was 54.3 years±SD of 9.49, three patients were male, and all had ≥1 risk factors of atherosclerosis. Patients received the evaluation of National Institutes of Health Stroke Scale (NIHSS), modified Rankin scale (mRS )and Barthel idex (BI) before and one-, three-, six-, and 12-month after the procedure. Results Stent success, defined as stent-assisted angioplasty successfully, resulting in ≤20% residual stenosis, was obtained in 35 lesions ( 97.2%, 35/36) and 33 patients ( 97.1%, 33/34). The stenosis rate of pre- and post -procedure was 80.5%± SD of 12.65 and 7.4%±SD 15.74, respectively. The Procedure-related complications were 8.3% for lesion (3/36) and 8.8% for patient (3/34), included 1 acute thrombosis, which obtained complete patency by means of intrathrombus thombolysis at once without sequelae, and 2 ischemic perforator strokes (1 irreversible stroke and 1 reversible). The disable stroke, defined as one that led to mRS score of ≥2, 30 days after the stroke, occurred in one patient ( 2.9%, 1/34; mRS of 2). Procedure success, defined as stent success without disable stroke or death at discharge by means of the endovascular therapy, was achieved in 33 lesions ( 91.7%, 33/36) and in 31 patients ( 91.2%, 31/34). Treatment success, defined as stent success without disable stroke and death at the 30th day, by means of the endovascular and medical therapy, was obtained in 34 lesions ( 94.4%, 34/36) and 32 patients ( 94.1%, 32/34). Clinical Follow-up, median 170 days (ranged from 30 days to 273 days; ≥1 month, n=34; ≥3 months, n=23; ≥6 months, n=13), was performed in 34 patients. There were no ischemic neurological events and death occurred. Cumulated disable stroke occurred in 1 patient ( 2.9%, 1/34). NIHSS was 1.09±SD of 1.694 and 0.47±SD of 1.051, before procedure and at the 30th day (n=34), respectively, and 0.57±SD of 0.992 at 3 months (n=23), 0.15±SD of 0.376 at 6 months (n=13), respectively; mRS was 0.65±SD of 0.812 and 0.47±SD of 0.563, before procedure and at 30 days, respectively, and 0.61±SD of 0.583 at 3 months, 0.38±SD of 0.506 at 6 months, respectively; and BI was 97.54±SD of 5.918 and 99.26±SD of 2.179, before procedure and at 30 days, respectively, and 99.35±SD of 2.288 at 3 months, 100.00±SD | Wei-Jian Jiang, MD Min Jin, MD Bin Du, MD Yong-Jun Wang, MD Xiao-Tong Xu, MD Qing-He Wang, MD Ning Ma, MD Long-Yi Wang, MO Jian-Ping Dai, MD From the Neurovascular Angioplasty Team, Department of Neurology and Neuroradiology, Beijing Tiantan Hospital, Capital University of Medical Sciences, Beijing, China.

| 15 | Synthesis of cystine C_(60) derivative and its protective effects on hydrogen peroxide-induced apoptosis in PC12 cells显示文摘Oxidative stress has been considered as a major cause of cellular injuries in a variety of clinical abnormalities, especially prominent in neural diseases. One of the usable ways to prevent the reactive oxygen species (ROS)-mediated cellular injury is dietary or pharmaceutical augmentation of some free radical scavenger. Water-soluble amino-fullerene is a novel compound that behaves as a free radical scavenger with excellent biology consistent. In the present study, we have synthesized and characterized a novel cystine C60 derivative for the first time, and investigated the effects on hydrogen peroxide-induced oxidative stress and apoptotic death in cultured rat pheochromocytoma (PC12) cells. PC12 cells treated with hydrogen peroxide underwent apoptotic death as determined by MTT, PI/Hoechst 33342 staining and flow cytometry analysis. These results suggested that cystine C60 derivative has the potential to prevent oxidative stress-induced cell death and has no evident toxicity. | Zhen Hu, Hai Ping Xing, Zhou Zhu, Wei Wang, Wen Chao Guan Department of Chemistry, Huazhong University of Science and Technology, Wuhan 430074, China Department of Neurology, Tongji Hospital, Tongji Medical College, Wuhan 430030, China | 2007 | Chinese Chemical Letters2007，18，2： | 2 |

| 18 | Association between apolipoprotein E promoter-219G/T polymorphism and total cholesterol level in patients with Alzheimer disease显示文摘BACKGROUND: Many researches have suggested that apolipoprotein E (APOE) and total cholesterol metabolism are closely related with dementia. In the supposed theory, 219 site of APOE promoter region is near gene coding region, so its polymorphism may result in the abnormality of APOE gene and protein expression, and finally lead to dementia. OBJECTIVE: To observe the association between APOE promoter-219G/T polymorphisms with serum total cholesterol in patients with Alzheimer disease, and compare it with non-dementia people. DESIGN: Case-control, comparative observation. SETTING: Department of Neurology, Fengtian Hospital of Shenyang Medical College. PARTICIPANTS: Fifty-five dementia patients including 27 males and 28 females aged (66±3) years and treated in the Department of Neurology, Fengtian Hospital were selected from January 2002 to December 2005 as the Alzheimer disease group. They all diagnosed according to the DSM-Ⅳdiagnostic criteria of Alzheimer disease instituted by American Psychiatry Association in 1994. Meanwhile, 44 none-dementia patients including 21 males and 23 females aged (66±3) years were selected from other clinical departments of Fengtian Hospital as control group. All the participants were informed the detection and agreed. METHODS: Genomic DNA was extracted from the peripheral blood of all subjects, then 'NEST'PCR, DNA sequence and enzyme digestion were adopted to detect the expression of APOE promoter-219 polymorphism, following by biomedical statistics analysis based on the clinical total cholesterol level. MAIN OUTCOME MEASURES: Polymorphism of APOE promoter-219 G/T and total cholesterol level. RESULTS: All 55 dementia patients and 44 non-dementia ones were involved in the result analysis. ①Allele and genotype frequency: The T allele frequency of the Alzheimer disease group was significantly higher than that in the control group [88.2% (97/110), 54.5% (48/88)], while G allele frequency was remarkably lower than that in the control group [11.8%(13/110), 45.5%(40/88), χ2=8.2, P < 0.01]. The TT allele frequency of the Alzheimer disease group was significantly higher than that in the control group [76% (42/55), 48% (21/44)], while GT+GG allele frequency was remarkably lower than that in the control group [24%(13/55), 52%(23/44), χ2=8.7, P < 0.01]. ②Total cholesterol level: The level of the TT genotype patients in the Alzheimer group was obviously higher than that in GT+GG genotype patients (t =2.46, P < 0.05); the cholesterol level in the two genotypes of the control group was similar (P > 0.05). CONCLUSION: TT genotype and allele T in the APOE promoter-219 polymorphisms are the sensitive gene, and genotype TT has a relationship with the increase of total cholesterol level. | Fang Liu1,2, Xiao Sun1, Jing Wang1, Yan Kong1, Li Cui1, Xiangdang Shi2 1Department of Neurology, Fengtian Hospital, Shenyang Medical College, Shenyang 110024, Liaoning Province, China 2Medical University of South Carolina, SC, U.S.A | 2006 | Neural Regeneration Research2006，1，9： | 1 |
