Objective To investigate the role of temporary placement of fully covered self-expandable metal stent (cSEMS) for treatment of uncontrolled bleeding after endoscopic sphincterotomy (EST).Methods From January 2000 to present,a total of 3460 cases of EST were performed,and bleeding after the procedure was complicated in 29 (0.84%) of them,in which 4 could not to be stopped by conventional managements.Covered SEMSs were placed across the major papilla in these 4 patients.Results The stents were successfully placed and hemostasis was achieved in all patients.The stent was removed in 1 patient 1 week later,and spontaneous stent dislodgment occurred in 1 patient within 4 weeks.The other 2 patients rejected to remove the stents,and the patency maintained for more than 6 and 12 months respectively.No complication was observed in procedures of placing and removing stents.Conclusion Covered SEMS placement is a safe,effective and simple method for patients with uncontrolled bleeding after EST.
2.Neuronal nicotinic acetylcholine receptor-mediated Ca~(2+) signals and regulation
Chinese Journal of Clinical Pharmacology and Therapeutics 1999;0(04):-
Neuronal nicotinic acetylcholine receptors(nAChRs) are widely distributed in the central nervous system,and they participate in complex neuronal signal transduction and regulation in the brain.The high Ca~(2+) permeability of nAChRs,plays a pivotal role in shaping nAChRs-induced neuromodulatory effects.The nAChRs-mediated Ca~(2+) signals may regulate diverse neuronal activities such as the improvement of learning and memory,and are closely related to drug addiction or neuroprotection mechanism.

Objective To scrutinize the positioning accuracy and reproducibility of the cone-beam computed tomography system in combination with the six-degree couch table (Hexapod Robot Treatment Table, HRTT). Methods The mechanical stability of the X-ray volume imaging (XVI) system was tested,in terms of the reproducibility. And the influence of the moveable parts, including the KV panel and the source arm, on the accuracy of the XVI image registration was analyzed. The accuracy between the bone and grey value registration was compared using a head-and-neck phantom. The accuracy of the HRTT for translational, rotational, and a combination of translational and rotational corrections was investigated in consecutive measurements. Results The performance of XVI system itself was stable with translational and rotational error of below 0. 4 mm and below 0. 3°, respectively. The mean position accuracy of the XVI system in combination with the HRTT summarized over all measurements was below 0. 6 mm and below 0. 4° for translational and rotational corrections, respectively. The grey value match was more accurate than the bone match. Conclusions The XVI image acquisition and registration procedure were highly reproducible.Both translational and rotational positioning errors can be corrected very precisely with the HRTT. The HRTT is therefore well suited to complement CBCT to take full advantage of position correction in six degrees of freedom for image guided radiotherapy.
