Objective To explore the application of self-expanding stent and seperable detachable coil for interventional therapy in patients with wide-necked intracranial aneurysm.Methods 32 patients with wide-necked intracranial aneurysm received the interventional therapy by self-expanding stent and seperable detachable coil.After operation,the situation of the aneurysm occluded were observed by DSA immediately and followed up.Results The stents were successfully deployed in the 32 patients.The seperable detachable coils were occluded in the aneurysms in 29 cases.After operation immediately,the DSA showed that the aneurysms in 18 cases were completely occluded by seperable detachable coils,7 cases were 95% occluded,4 cases were 90% occluded.In the other 3 cases,the aneurysms were too small to be filled by seperable detachable coil,the stents were used only.All the parent arteries were no stenosis.18 h after operation,1 case died from multiple hemorrhage caused by thrombasthenia.Follow-up from 3 months to 1 year,DSA re-examination in 21 cases.Compared with the image immediately after operation,the imagings of DSA were no change in 12 cases,residual necks were disappeared in 5 cases and increased in 1 case.In the 3 cases which stents used only,the aneurysms were no development completely in the 2 cases and decreased in 1 case.6～18 months followed up in 26 cases,the rebleeding and cerebral infarction were no occurred.Conclusions The self-expanding stent is very flexible,secure,and effective.It can good support for the wide-necked aneurysms to be occluded by seperable detachable coils and effective promoting the small aneurysms healing.

To collect small molecule drugs and their drug target data such as enzymes, ion channels, G-protein-coupled receptors and nuclear receptors from KEGG database as the training sets, in order to establish drug-target interaction models based on the random forest algorithm. The accuracies of the models were evaluated by the 10-fold cross-validation test, showing that the predicted success rates of the four drug target models were 71.34%, 67.08%, 73.17% and 67.83%, respectively. The models were adopted to predict the targets of 26 chemical components and establish the compound-target-disease network. The results were well verified by literatures. The models established in this paper are highly accurate, and can be used to discover potential targets in other traditional Chinese medicine ingredients.

To study the effect of cholesterol and 25-OH-cholesterol on cholesterol metabolism in HepG2 cells and the effect of coptisine (Cop) extracted from Coptidis Rhizoma (CR) in reducing and regulating cholesterol. In this study, TC, TG, LDL-c and HDL-c were measured by biochemical analysis; mRNA and protein expressions of LDLR, HMGCR and CYP7A1 were detected by qRT-PCR and Western blot. According to the results, cholesterol and 25-OH-cholesterol inducing could decrease in mRNA and protein expressions of LDLR and CYP7A1, so as to increase TC and LDL-c contents. However, Cop could up-regulate mRNA and protein expressions of LDLR and CYP7A1 and down-regulate that of HMGCR, so as to reduce TC and LDL-c levels. These findings suggested that Cop has potential pharmacological activity for reducing cholesterol, and may reduce cholesterol by regulating mRNA and protein expressions of key genes involved in cholesterol metabolism, such as LDLR, CYP7A1 and HMGCR. This study laid a firm theoretical foundation for developing new natural drugs with the cholesterol-lowering activity.

Objective To investigate the assoiation between rheumatoid arthritis(RA)and the pres- ence of the shared epitope(SE)of HLA-DRBI gene in Han nationality of Neimenggu population.Methods The method of DNA amplification with sequence-specific primers(PCR-SSP)was used to determine 17 alleles of HLA-DRB1*01,*04,*10 genotypes in 80 RA patients and 110 healthy controls from the Han nationality population in Neimenggu.Results The frequencies of SE were significantly increased in RA patiens com- pared with controls(48.8%:20%,P＜0.01).Epitope analysis revealed that the most predominant allele subtype of DR4(*0405)was usceptible sequence in Neimenggu patients with RA(28.8%:12%,P＜0.01).No statisticall significant difference of other subtypes of DR1,DR4 nd DR10 was noted including DRB1*0101(2.5%:0.9%), *0102(2.5%:0),*0103(1.25%:0.9%),*0104(2.5%:0),*0401(6.25:1.8%),*0402(3.75%:0.9%),*0403 (1.25%:1.8%),*0404(2.5%:1.8%),*0406(2.5%:2.7%),*0407(1.25%:0.9%),*0408(3.75 %:0.9%),*0409 (1.25%:0),*0410(2.5%:0.9%),*0411(0:0)and *1001(8.75%:4.5%)respectively.Logistic regression analy- sis showed that the disease of patients with SE homozgote was more severe than that of patients with heterozy- gote(P＜0.01).Conclusion The results suggest that there is an association between SE of HLA-DRBI gene and susceptibility and severity of RA,especially,HLA-DR4 subtypes are strongly associated with RA in Han nationality in Neimenggu population.

Objective To study osteogenic courses and features of human osteoblasts cultured in vitro and seeded into alloplastic decalcified cancellous bone.Methods Human osteoblasts isolated from normal human perios- teum were cultured and amplified in vitro.Thy configuration and developing manners of osteoblasts were observed. Then osteoblasts were seeded into alloplastic decalcified cancellous bone.Thy composites were implanted and cultured in thy body of athymic mice.The specimens were obtained 8 weeks later.Osteogenic characteristics were observed by scanning electron microscope.Results Osteoblasts isolated from human periosteum developed well and proliferated rapidly in vitro.Island new bone formation could be observed histologically 8 weeks after the composites of os- teoblasts and alloplasric decalcified cancellous bone were implanted and cultured in the body of athymic mice.Conclu- sion Calcified bone can be formed by seeding osteoblasts into alloplastic decalcified cancellous bone,which may be a new kind of bone graft source to construct bone defects.

Objective To study the changes of insulin- like growth factor- 1(IGF-1)in blood and cerebrospinal fluid (CSF) in children with viral encephalitis (VE).Methods The IGF-1 levels in blood and CSF were determined before treatment by ELISA in 25 children who admitted with VE, including 15 cases with severe VE and another 10 cases with mild VE, 10 children served as con-trols. Results Before treatment, the blood IGF-1 levels in VE group were significantly lower than those of controls, but the CSF IGF-1 levels were significantly higher than those of controls(P0.05), but the blood IGF-1 levels in serve VE group were significanfly lower than those of mild VE group and controls(P

OBJECTIVETo observe the clinical efficacy of Qinghuang Powder combined with Chinese herbs for reinforcing Shen and strenghening Pi in treating myelodysplastic syndrome (MDS).

METHODSfifty-five patients with diagnosis fitting to MDS were treated with Qinghuang Powder and decoction for strengthening Pi and reinforcing Shen, in combination with Stanozololum.

RESULTSEleven patients (20.0%) out of the 55 were completely remitted (CR), the total effective rate being 74.5% (41/55 cases). By FAB typing, 9 (26. 5%) in the 34 patients of type RA/RAS were CR, with the total effective rate of 82.4% (28/34 cases), and in the 21 patients of type RAEB, 9.5% (2/21 cases) were CR with the total effective rate of 61.9% (13/21 cases), showing insignificant statistical difference between the two types (P > 0.05). By international prognostic scoring system (IPSS), the treatment was evaluated as CR in 10 patients, effective in 25 and ineffective in 11 in 36 patients of moderate risk group I , the responding numbers were 1, 4, 2 in 7 patients of moderate risk group II and 0, 3, 3 in 6 patients of high risk group, respectively, also showing insignificant difference between groups (P > 0.05). Levels of Hb, WBC and platelet significantly increased after treatment (P < 0. 05). By cytogenetics, the effective rate was 68.8% (11/16 cases) in patients with abnormal chromosome and 72.7% (24/33 cases) in those with normal chromosome, with insignificant difference (P > 0.05).

CONCLUSIONThe comprehensive therapy with TCM treatment for reinforcing Shen and dissolving stasis in dominance has a definite clinical effect in treating MDS, it was not significantly associated with FAB typing, IPSS score, and chromosome abnormality of patients.
