Objective To observe the effects of ilexonin A (IA) on IL-6 and M-CSF following ballon angioplasty in rabbit common carotide artery to provide experimental basis for percutaneous coronary interventions. Methods 30 Japanese rabbits were fed with high cholesterol food for 4 weeks. Then they were divided into three groups randomly. Each group had ten rabbits. ①Control group: the incision was sew directly after right carotide artery of the rabbit was seeked. ②Balloon dilation group:the proximal of the carotide artery was cuted,the ballon was delivered and distended,after it was drawn repeatly,the incision was closed. ③IA therapy group: operation was the same to the balloon dilation group,then IA was administered in vein.All of them were fed with high cholesterol diet for 4 weeks and the blood samples were collected 1 d before the operation and 1 d,1,2,4 weeks after the operation. The serum IL-6 and M-CSF levels were determined with radioimmunoassay.The pathological changes of injuried artery were observed. Results ①The IL-6 level in balloon dilation group was higher than that in IA therapy group after the operation (P

Objective To analyze the clinical risk factors of hemorrhagic transformation (HT) of cardiogenic cerebral embolism and the influence of HT on outcome. Methods The clinical data of 115 inpatients were reviewed from May, 2012 to December, 2015. They were di-vided into HT group (n=58) and non-HT group (n=57). The age, anticoagulant therapy, thrombolytic therapy, infarction diameter, diabetes, coronary heart disease, hyperlipidemia, the National Institutes of Health Stroke Scale (NIHSS) score and HAS-BLED score were compared. The risk factors for HT was screened with the multivariate Logistic regression. NIHSS score and Modified Rankin Scale (mRS) score as hos-pitalization, and one month and three months after stroke were compared. Results There were significant difference in NIHSS score (t=-2.991, P=0.003) and HAS-BLED score (t=-2.499, P=0.014), as well as infarction diameter (χ2=8.355, P=0.004) between HT group and non-HT group. NIHSS score (OR=1.127, P=0.027), HAS-BLED score (OR=1.783, P=0.03) and infarction diameter (OR=4.390, P=0.035) were the risk factors for HT. The incidence of HT was less in low-risk group (HAS-BLED score=0-2) than in high-risk group (HAS-BLED score≥3) (χ2=4.643, P=0.031). The NIHSS score as hospitalization, and one month and three months after stroke were all more in HT group than in non-HT group (t>2.387, P<0.05). The mRS score was more in HT group as hospitalization (t=-2.262, P=0.026), but not significant one and three months later (t<1.468, P>0.05). Conclusion HT tends to happen in the patients of cerebral embolism patients after atrial fibril-lation with severe neural function defect, large infarction diameter and high HAS-BLED score. The neural function is poor in those with HT.

Objective To study the optimum combination of orientation parameter of total hip prosthesis and acetabular safe zone on condition that the range of motion for activities of daily living (ADL) is fulfilled.Methods A three-dimensional generic parametric and visually kinematic simulation module of THA was developed.Range of motion ( ROM ) of hip flexion ≥ 110°,internal-rotation ≥30° at 90° flexion,extension ≥30° and external rotation ≥40° were defined as the normal criteria for ADL.ROM of hip flexion ≥ 120°,internal-rotation ≥45° at 90° flexion,extension ≥30° and external rotation ≥40° were as the severe criteria.The ranges of changes in general ratios (GRs) of head-neck,femoral neck antevemion ( FNA ),operative inclination (OI) and anteversion (OA) of acetabulur components were 2.0-2.92,0°-30°,10°-60°,and 0°-70° respectively.Within the limits of the upper two activity criteria,the synchronous OA of acetabulur components was calculated with every 5°change in OI of the cup,and the collodiaphyseal angle ( CDD ) was set as 135°.The safe-zone of combination of acetabulur operative anteversion (OA) and inclination (OI) was defined as the area that fulfilled the two mentioned criteria of ROM without cup-neck impingement.All parameters were analyzed by using SAS 6.12 software.Results The safe zone of acetabdar angle rose with the increase of GRs of head-neck and the safe zone of severe criteria was smaller than that of normal criteria.When the CDD angle was 135°,the sum of average aeetabular OA and acetahular OI plus 0.816 times of the FNA equaled to 84.76° innormal criteria; and the sum of average acetabular OA and acetabular OI plus 0.873 times of the FNA equaled to 92.04° in severe criteria.Conclusions A high GR of head-neck greatly increases the size of safe-zone of acetabular angle.The higher demand of ROM of hip joint requires the smaller safe zone of acetabular angle,as can be corrected by increasing the GR of head-neck.The optimum combination between the sum of average acetabular OA and acetabular OI ( Y) plus FA (X)in the normal criteria and severe criteria can be estimated by using the following formulae:Y1 =-0.816X1 + 84.76 (R2 =0.993 ),Y2 =-0.873X2 + 92.04( R2 =0.999) respectively.

Objective To analyze the relevance between the consumption of various antimicrobials and antimicrobial re-sistance of Acinetobacter baumanni in a grade three hospital during 2007 -2010 .Methods A retrospective analysis was per-formed to count and sort the defined daily doses (DDDs) and the consumption of various antimicrobials in the hospital between 2007 and 2010 .Meanwhile the resistance rates of Acinetobacter baumanni to different antimicrobials were collected in the same period .Data was analyzed by SAS 8 .2 statistical software package using Spearman correlation method .Results The resistance rate of Acinetobacter baumanni to imipenem was significantly positively correlated with the consumption of carbapenems (r=0 .954 6 ,P<0 .01) ,it is positively correlated with the dosage of imipenem (r=0 .849 2 ,P<0 .05) ,it is also significantly posi-tively correlated with the consumption of meropenem (r=0 .999 2 ,P<0 .05) ,and the consumption of amoxicillin/clavulanate potassium ,respectively(r=0 .800 5 ,P<0 .05) .There was no correlation between the resistance rate of Acinetobacter bauman-ni and the dosage of aminoglycosides ,fluoroquinolones ,even β-lactamase inhibitors(P>0 .05) .Conclusion The use of car-bapenems should be correlated with their indications strictly ,only applying to severe infection of Acinetobacter baumanni .The aminoglycosides of amikacin and β-lactamase inhibitors of cefoperazone/sulbactam are the better options to treat A cinetobacter baumanni infection .

In addition to causing high disability and high fatality rates, ruptured intracranial aneurysms can also cause cognitive impairment. Although preventive surgical treatment can avoid intracranial aneurysm rupture and bleeding, patients may still have a certain degree of cognitive impairment, even in patients with good clinical recovery after surgery. There is no systematic review on the effect of different surgical methods on cognitive function, and the best surgical method is still inconclusive. This article reviews the cognitive impairment in patients with intracranial aneurysm, hoping to provide a basis for clinical treatment decisions.
