OBJeCTIve：To assess the efifcacy and safety of cilostazol on the progression and regression of symptomatic intracranial artery stenosis. DATA ReTRIvAL： We searched the main databases for eligible trials including Medline （from 1966 to June 2014）, Embase （from 1980 to June 2014）, Cochrane Library （Issue 6, 2014）, Chinese National Knowledge Infrastructure （from 1995 to June 2014）, Current Controlled Trials （http：//***）, Clinical *** （http：//***）, and Chinese Clinical Trial Registry （http：//***）. All studies regarding prevention and treatment of symptomatic intracranial arterial stenosis by cilostazol were collected. The Mesh or text keywords were the En-glish words： “cilostazol, phosphodiesterase 3 inhibitor, atherosclerosis, and ischemic stroke.” No restrictions were put on publications or publication language. SeLeCTION CRITeRIA：Grade A or B randomized controlled trials were selected according to the quality of evaluation criteria from the Cochrane Collaboration, in which cilostazol and aspi-rin were used to evaluate the effects of cilostazol in the treatment of patients with symptomatic intracranial artery stenosis. The quality of study methodology was evaluated based on criteria de-scribed in Cochrane Reviewer’s Handbook 5.0.1. RevMan 5.2 software was used for data analysis. MAIN OUTCOMe MeASUReS： Clinical efifcacy and safety of cilostazol in stopping progression and promoting regression of symptomatic intracranial artery stenosis were measured by magnet-ic resonance angiography and transcranial Doppler. ReSULTS：Two randomized controlled trials with a total of 203 patients were included in this study. The results showed that while cilostazol was associated with a significantly reduced progression of intracranial artery stenosis （OR = 0.21, 95%CI： 0.09–0.47,P 〈 0.01）, it had no beneifcial effect on symptom regression （OR = 1.42, 95%CI： 0.80–2.51,P = 0.24）. During the follow-up period, although some adverse effects

Dear editor,Optical encoder is a kind of angle sensor, which has been applied in a variety of domains such as astronomy, vehicles and industrial production. However, there always exist errors between the measured angles and the real angles, reducing the performance and safety of systems. These measurement errors may raise from various sources, like

This paper presents a new control strategy based on current differential feedback to accelerate the dynamic response of electromagnetic actuators, instead of traditional closed-loop control based on displacement feedback. The method mainly includes a differentiator, proportioner and signal synthesizer. Analysis and simulation on the step characteristics of an electromagnetic actuator were discussed, and all the results show that the approach can improve the actuator's step response greatly. Finally, the control method is applied to a real gravure system which verifies the control performance.

It is demonstrated that barium and aluminum alloy synthesized by melting in a glass tube under low vacuum is applicable for organic laser emitting diodes(LEDs)as a thin film *** alloy film obtained by the thermal evaporation of pre-synthesized alloy is used in a single-boat organic LED device with the structure:indium tin oxide(ITO)/4,4'-bis[N−(1-naphthyl)-N−phenylamino]biphenyl(NPB)/tris-(8-hydroxyquinoline)aluminum(Alq3)/barium:aluminum *** experimental results show that devices with this alloy film cathode exhibit better current density-voltage-luminance characteristics than those with a conventional pure Al cathode,and more weight of barium in aluminum leads to better performance of the *** of current density versus voltage for the electron-only devices are fitted by the Richardson–Schottky emission model,indicating that the electron injection barrier has a decrease of about 0.3 eV by this alloy cathode.
