Objective： To evaluate the analgesic efficacy of controlled-release （CR） oxycodone and gabapentin in malignant neuropathic pain （NP）. Methods： Patients with malignant NP were enrolled and baseline pain intensity （PI） was recorded. They initially took one week CR oxycodone and were allocated to two different groups at day 8 by reevaluated PI. Patients with mild pain went to CR oxycodone mono-therapy group （OO group） and took another two weeks CR oxycodone. Others went to （CR oxycodone combined gabapentin group （OG group） and received additional gabapentin. Daily doses and side effects were recorded. Results： Fifty-eight （92.06%） of the 63 enrolled patients completed the initial week＇s therapy. Twenty-two （37.93%） went to OO group and PI significantly reduced at day 15 （2.00 vs. 2.62, P=0.004）, but not improved at day 22 （1.90 vs. 2.00, P=0.54）. Thirty-six （62.07%） patients went to OG group and PI was significantly reduced at day 15 （4,47 vs. 2.94, P〈0.001）, but not improved at day 22 （2.94 vs. 2.75, P=0.136）. Mean daily dose （MDD） of CR oxycodone at day 8 was 62.64 mg. It was significantly increased at days 15 and 22 （71.43 mg vs. 62.64 rag, P=0.021; 81.90 mg vs. 71.43 mg, P=0.004） in OO group. MDD of gabapentin was significantly increased at day 22 compared to day 15 （862.50 mg vs. 993.75 mg, P〈0.001）. Constipation was occurred in 13.64% of the patients in OO group and 14.26 % in OG group. Conclusion： Malignant NP may be well controlled by oxycodone mono-therapy. Early combination with gabapentin is sensible when pain is not satisfactory relieved by oxycodone alone. The side effects of them are manageable.

Broadband and perfect terahertz absorber based on multilayer metamaterial using cross-ring patterned structures is proposed and investigated. The structure of the absorber is double absorption layers consisting of a chromium cross ring and eight isosceles right triangles. The unique structure of the double absorbing layers excites the electric dipole multimode resonance, giving rise to high absorption performance. Meanwhile, the influence of construal parameters on absorber behavior is also discussed. The numerical results show that the absorption achieves over 90% ranging from 2.45 THz to 6.25 THz and 99% absorption in the range of 3.7—5.3 THz. The realization of broadband and perfect absorber is described using the impedance matching principle. It is obviously found that the absorber is insensitive to the high angle of incidence for both transverse electric(TE) and transverse magnetic(TM) polarizations. Compared with the former reports, this absorber has remarkable improved absorption efficiency and smaller period. The terahertz absorber may be found applications in the fields of energy capture and thermal detection.
