Objective To evaluate the effect of stellate ganglion block (SGB) on cerebral vasospasm in patients undergoing intracranial aneurysm surgery. Methods Forty ASA Ⅱ or Ⅲ patients aged 14-64 yr weighing 40-81 kg undergoing intracranial aneurysm clipping were randomly divided into 2 groups ( n = 20 each): group control (group C) and group SGB. Left SGB was performed with 0.25% ropivacaine 10 ml immediately after intubation. Successful block was verified by development of Homer syndrome within 15 min after block. Anesthesia was induced with midazolam, propofol, fentanyl and vecuronium and maintained with isoflurane inhalation and intermittent iv boluses of fcntanyl and vecuronium. The patients were intubated and mechanically ventilated. PETCO2 was maintained at 30-35 mm Hg. BIS was maintained at 50-60. Right internal jugular vein was cannulated and the catheter was threaded cranially until resistance was met for blood sampling. Blood samples were collected before skin incision (T1), before clipping of aneurysm (T2), at 30 min after clipping (T3 ), and at the end of surgery (T4) for determination of plasma concentrations of endothelin (ET), calcium gene-related peptide (CGRP) and S100B protein. Transcranial Doppler was used to measure the flow rate of blood in bilateral middle cerebral artery and extracranial carotid artery at 1 and 3 days after surgery. All patients were observed for incidence of brain ischemia during 1-7 days after surgery. Results Plasma ET and S100B protein concentrations were significantly decreased, while plasma CGRP concentration was significantly increased after clipping of aneurysm at T3 and T4 in group SGB as compared with group C. The incidence of cerebral vasospasm and brain ischemia was significantly lower in group SGB than in group C. Conclusion SGB performed before operation can significantly reduce the incidence of cerebral vasospasm after clipping of intracranial aneurysm by inhibiting the release of ET and promoting the release of CGRP.

Real-time free breathing cardiac cine imaging is a reproducible method with shorter acquisition time and without breath-hold for cardiac magnetic resonance imaging. However, the detection of end-diastole and end-systole frames of real-time free breathing cardiac cine imaging for left ventricle function analysis is commonly completed by visual identification, which is time-consuming and laborious. In order to save processing time, we propose a method for semi-automatic identification of end-diastole and end-systole frames. The method fits respiratory motion signal and acquires the expiration phase, end-diastole and end-systole frames by cross correlation coefficient. The procedure successfully worked on ten healthy volunteers and validated by the analysis of left ventricle function compared to the standard breath-hold steady-state free precession cardiac cine imaging without any significant statistical differences. The results demonstrated that the present method could correctly detect end-diastole and end-systole frames. In the future, this technique may be used for rapid left ventricle function analysis in clinic.

Objective: To establish a risk prediction model and scoring system in patients with side branch (SB) occlusion during coronary bifurcation intervention. Methods: A total of 7007 consecutive patients who received percutanenous coronary intervention (PCI) in our hospital from 2012-02 to 2012-07 were recruited and 1545 patients (with 1601 bifurcation lesions) treated by single stent technique or main vessel stenting ifrst strategy were selected for our study. According to weather SB occlusion occurred during operation, the lesions were divided into 2 groups: Non-SB occlusion group,n=1431 and SB occlusion group,n=114. The data set of the ifrst 1200/1601 lesions by time sequence, was used for establishing the risk model and scoring system, the data set of rest 401 lesions was used for model validation. Results: The modeling data set presented that the relationship between pre-operative main vessel plaque and the position of branch vessel, the main blood vessel pre-stenting TIMI grade, the stenosis degree of pre-operative bifurcation nucleus, the angle of pre-operative bifurcation and the ratio of pre-senting stenosis degree of branch diameter and pre-operative main vessel to branch vessel diameter were the independent risk factors for branch occlusion. The risk model ROC=0.80, 95% CI 0.75-0.85, Hosmer-Lemeshow HLP=1.00; the scoring system ROC=0.76, 95% CI 0.71-0.82, HLP=0.12. The validation data set ROC=0.81, 95% CI 0.73-0.89, HLP=0.77; the scoring system ROC=0.77, 95% CI 0.69-0.86, HLP=0.58. The quartile integration of both data sets indicated that the patients with the integration score ≥ 10 had the higher risk for SB occlusion than those with integration score < 10 during the operation,P<0.001. Conclusion: Our research developed a simple and user-friendly system, it may distinguish the patients with high risk of SB occlusion during bifurcation intervention by quantitative stratiifcation of coronary angiographic imaging.
