Objective To evaluate the cost-effectiveness of the aneurysm intra-artery GDC embolization and the aneurysm clapping of intracranial aneurysm, and to give the instruction for the clinical practice. Methods A case control study (1 vs. 1) was developed to evaluate the cost in hospital, the cost for return visit and the Quality-adusted Life-Year (QALY) and lifetime costs of the intra-artery GDC embolization and the aneurysm clapping of intracranial aneurysm, under the matching of the age, sex, living place, the size and place of the aneurysm, and the Hunt & Hess score. Clinically effectiveness dates were derived from the medical records. Cost dates were derived from follow-up by telephones or letters. The correlation analysis was done with the SPSS 13. 0. Results The cost in hospital in AC group was (54 945±16 946) RMBs,which washigher than the ones in AE group(63 768±12 665) RMBs, (t = 1.71, P <0. 05). The cost of missed working in AE group was 200 RMBs(the median), which was lower than the ones in AC group 650 RMBs (z =2. 57,P < 0. 01). The cost of return visit in AE group was 1200 RMBs, which was lower than the ones in AC group1950 RMBs (z = 1.82, P < 0. 05). The cost-effectiveness of the intra-artery GDC emhalization and the aneurysm clapping had no difference 3805 RMBs/year vs. 3028 RMBs/year(z =0. 42,P >0. 05). Conclusion The results suggest that the two therapies have no difference in cost effective rate. Considering the physical and mental loss, the aneurysm intra-artery GDC embolization was better than the aneurysm clapping for the patients with aneurysm that diameter less than 25 mm.

Objectives To explore the effect of type A personality and type D personality on coronary heart disease (CHD) ,and the influence of the two kinds of personality factors with the risk factors of CHD. Methods 123 CHD patients and 116 healthy subjects were randomly chosen to answer the questionnaire of general situation and type A behavior questionnaire(TABQ) and type D personality scale(DS14) and assay the fasting glucose ( GLU ), total cholesterol ( TC ) and triglycerides ( TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) ,very low density lipoprotein (VLDL). Results ( 1 )The detection rate of type A personality were respectively 66.7% in CHD group and 40.5% in control group,while type D personality were respectively 39.8% in CHD group and 22.4% in control group (P ＜ 0. 05 ). ( 2 ) There were significant differences in total TABPQ,TH, CH , SI, NA scores between the two groups(P＜ 0.05 ). (3)Coronary heart disease had correlated with gender,history of hypertension, HDL, LDL, GLU and negative affectivity. Conclusion Negative affectivity plays an important role in CHD.

Cascade in cerebral ischemic injury may cause cholinergic dysfunction,inflammation and oxidative stress. It plays an important role in the pathological processes of vascular dementia. A large amount of basic research has confirmed that cholinesterase inhibitor and N-methyl-d-aspartate receptor inhibitor may improve cognitive function in patients with vascular dementia. However, the efficacy of these drugs has been confirmed in only a part of the patients, and their safety and efficiency have not achieved the expected results. Thus, it needs further study and exploration.

Objective To evaluate the value of the transnasal esophagogastrodudenoseopy(EGD)in clinical diagnosis and therapy.Methods The study includes 1000 patients referred for diagnostic and therapie EGD.All patients were received the examination after 2%lidocaine was administered into the uaris.We obtained biopsy specimens from 824 patients.Results Among the 1000 patients,971 were completed successfully by transnasal EGD,and the remaining was completed by classical transoral EGD.During the examination,we extracted the esopha6eal foreign body in two patients.and performed the pyloric stenting in one patient.Enteral feeding tubes were placed in 18 pafients.We found that the endoscopic manifestation is consistent with the histopathologic examination(the concordance rate is 84%).Conclusion The transnasal EGD has the goodish value in the clinical diagnosis and therapy.

The discovery of limbal stem cells is the key advancement in ophthalmology in the 20th century.Many clinical researches have proved that limbal stem cells transplantation is an effective method to treat severe ocular surface diseases.However, some important issues associated with the identification,isolation,standardized culture in vitro and differentiation after transplantation are still not clear and need to be paid more attention.Strengthening the underlaying research in this field will play important role in treating corneal blindness.

Objective To assess whether echocardiographic parameters of M-mode,pulsed-wave Doppler and tissue Doppler imaging which were usually used for selecting cardiac resynchronization therapy (CRT) candidates could predict CRT responders.Methods Twenty-nine patients with NYHA class Ⅲ or Ⅳ heart failure,left ventricular ejection fraction(LVEF)≤35%,QRS≥130 ms were enrolled.All of them underwent biventricular pacemaker implantation.The septal-to-posterior wall motion delay(SPWMD) from M-mode recording,and the standard deviation of time to peak systolic velocity(Ts-SD) were used to evaluate intraventricular dyssynchrony.The interventricular mechanical delay (IVMD) by pulsed Doppler echocardiography was calculated by subtracting the right ventricular preejection intervals (RV-PEI:the onset of the QRS on the electrocardiogram to the onset of pulmonary outflow) from the left ventricular preejection intervals (LV-PEI:the onset of the QRS on the electrocardiogram to the onset of aortic outflow).At least 15 % reduction in left ventricular end-systolic volume(LVESV) at the 6-month after CRT was defined as responder.Results In the 29 patients,there were 20 (68.97%) responders.The area under the receiver operating curve(ROC) of SPWMD,Ts-SD,LV-PEI,RV-PEI and IVMD to predict CRT responders was 0.448 (95% CI 0.184-0.712,P＞0.05),0.557 (95% CI 0.317-0.798,P＞0.05),0.479 (95% CI 0.186-0.773,P＞0.05),0.568 (95 % CI 0.272-0.863,P＞0.05) and 0.411 (95% CI0.136-0.687,P＞0.05),respectively.Conclusions M-mode echocardiography,pulsed Doppler and tissue Doppler imaging failed to predict CRT responders.New echocardiographic techniques including threedimensional echocardiography and speckle tracking image will be investigated,and may improve the predictive power.

Objective To evaluate left ventricular torsion in patients after coronary artery bypass graft(CABG) surgery by velocity vector imaging(VVI). Methods Twelve patients who were scheduled to have CABG surgery were enrolled. VVI offline software was used to evaluate myocardial rotation in both basal and apical segment before and three months after CABG. The rotation and rotation rate of each a counterclockwise rotation at the apex and a clockwise rotation at the base, and the absolute value of CABG the rotation at the base was significantly improved than that before CABG (P <0.001), and the rotation in the segment of anterior septum, anterior wail and inferior septum at the base was higher than that rotation in the apical and basal segment three months after CABG was also significantly higher than that negative peak rotation rate in the early diastolic period at the apex were significantly higher than those at the improved than that before CABG (P <0.001). And the positive peak rotation of the systolic period in the segment of anterior septum,anterior wall,lateral wall and inferior septum and the negative peak rotation of the diastolic period in the segment of anterior and inferior septum at the base were also higher than those before CABG (P <0.001). Conclusions VVI is a useful method which can quantitatively assess left ventrieular torsion in patients before and after CABG surgery.
