The alkylation of wanpeinine A formed 3β,6α-dimethoxymethylwanpeinine A (7). Conclusion All compounds are new except for 3β,6α-diacetylwanpeinine A.

Objective To observe the effects of different compatibility ratios of Astragali Radix and Angelicae Sinensis Radix on vascular intimal hyperplasia; To ascertain the effective compatibility of Astragali Radix and Angelicae Sinensis Radix for antagonizing vascular intimal hyperplasia. Methods SD rats were divided into different groups by baseline geometric design method: Astragali Radix and Angelicae Sinensis Radix different compatibility ratios groups, Astragali Radix group, Angelicae Sinensis Radixgroup, positive medicinegroup and sham-operation group. A model of intimal hyperplasia of thoracoabdominal aorta was established by balloon catheter injury in vascular endothelium of rats. Then the thoracoabdominal aorta was taken out after gavage of Astragali Radix and Angelicae Sinensis Radix with different compatibility ratios for 14 days. Bloodletting was used to take thoracoabdominal aorta. Masson staining and Morphometric methods were used to analyze the intimal hyperplasia. Results IA, IT, HRIA and HRIT increased 14 day after intimal injury. Compared with the model group, IA, IT, HRIA and HRIT in Angelicae Sinensis Radix group, Astragali Radix and Angelicae Sinensis Radix 1:2 group, Astragali Radix and Angelicae Sinensis Radix 1:5 group, Astragali Radix and Angelicae Sinensis Radix 1:1 group and Astragali Radix and Angelicae Sinensis Radix 5:1 group were lower, and the effects of Astragali Radix and Angelicae Sinensis Radix 1:1 ratio were strongest. The effects on intimal hyperplasia in Astragali Radix group and Astragali Radix and Angelicae Sinensis 2:1 group had no significant differences compared with model group. Conclusion Astragali Radix and Angelicae Sinensis can inhibit vascular intimal hyperplasia in a certain compatibility ratios, and the effects of Astragali Radix and Angelicae Sinensis Radix 1:1 on intimal hyperplasia are the best.

Objective To study influencing factors in patients with rheumatic diseases.Methods One hundred and twenty patients with rheumatic diseases were selected from November 2013 to February 2014 in our hospital for the study.The influencing factors in patients with rheumatic diseases were obtained by proposed questionnaires,and then the univariate and multivariate Logistic regression analysis were performed to study factors affecting the treatment.Results Patients older than 50 of the observation group accounted for 38％ (18/48),the proportion of farmer,patients with primary school education level or below,and monthly income ＜3 000 RMB was 35％(17/48),60％(29/48),and 46％ (22/48) respectively.Compared with the control group,they were significantly higher than the control group,which were 64％(46/72),58％ (42/72),79％(57/72),65％(47/72) (x2=8.058,P=0.005; x2=6.025,P=0.014; x2=4.986,P=0.226; x2=4.456,P=0.035) respectively.Using the treatment as the dependent variable,age ≥50 years of age,farmer,primary school and lower education level,and monthly income ＜3 000 RMB as the independent variable,we carried out the regression analysis.Age (OR=1.124,95％CI:1.084-7.236),occupation (OR=1.871,95％CI:1.054-7.243),education level (OR=1.982,95％CI:1.157-6.256),monthly income (OR=1.363,95％CI:1.012-8.227) are the influencing factors of rheumatism's treatment.Conclusion The treatment of rheumatic diseases are influenced by many factors,and more societal support should be provided to help patients with rheumatic disease receive professional treatment and better control of the disease.

Objective To study the value of carotid plaque magnetic resonance imaging (MRI) in pre-operation assessment in the elderly patients with carotid atherosclerosis and explore the possibility of minimizing the contrast weightings to gain sweeptime. Methods Totally 70 elderly patients with cerebral ischemia (average age of 68.8 years) underwent carotid MRI and digital subtraction angiography (DSA) due to the appearance of carotid plaque detected by ultrasound. Carotid plaque MRI was acquired with 3.0T MR scanner and 8 channel surface coil. The standard carotid plague MRI program included pre-and post-contrast T1 weighted imaging (T1WI), T2 weighted imaging, proton density weighted imaging and 3D time of flight MR angiography (3D TOF MRA). All these program were divided into two combinations: the 5-sequence MRI (all the sequences) and 2-sequence MRI (T1WI and TOF MRA). Digital subtraction angiography (DSA) in coronal and lateral views of carotid artery was performed with GE Advantx LCN+. The software SPSS 13.0 was used to statistically analyze the difference between MRI and DSA, and that of two sequence combinations was used in the detection of luminal stenosis and fibrous cap (FC) rupture. Results Totally 135 arteries were analyzed while 3 arteries in one patient were excluded due to the poor quality image and stent placement. The degree of luminal stenosis were (38.3±31.0)% and (38.5±30.9)%, respectively, detected by the two MRI sequence-combination with no significant difference (t=2.447, P＞0.05) and was (35.1±31.8)% by DSA. There was a good concordance between MRI and DSA in luminal stenosis detection (Kappa value: 0.773). No statistical difference was found between two MR sequence combinations in detecting FC rupture (both in 36 vessels). DSA detected FC rupture of 16 vessels, showing remarkably difference contrast to MRI(χ2=12.0, P＜0.01). Conclusions MRI can accurately detect the luminal stenosis and FC rupture. The short time scanning resulting from sequence optimization could make MRI much more suitable than DSA to do the pre-operation assessment for senile carotid atherosclerotic patients.
