作者： Xu GAO chuan zhong li Jing Song HE Department of Mathematics Ningbo UniversityNingbo 315211P.R.China

In this paper, we define a new constrained multi-component KP （cMKP） hierarchy which contains the constrained KP （cKP） hierarchy as a special case. We derive the recursion operator of the constrained multi-component KP hierarchy. As a special example, we also give the recursion operator of the constrained two-component KP hierarchy.

In this paper, we construct the generalized Heisenberg supermagnetic models with two different constraints and investigate the integrability of the super integrable systems. By virtue of the gauge transformation, their corresponding gauge equivalent counterparts are derived, i.e., the super and fermionic mixed derivative nonlinear Schr?dinger equations, respectively.

Flavones are main components of natural occurring flavonoils. It is well documented in the literatures that flavones are known to exhibit a wide variety of biological and pharmaceutical activities. Many of them have been used therapentically for the treatments of symptoms of chronic venous insufficiency, of varicose veins, of conditions and of diabetic retinopathy, etc.. Some flavones have

目的比较应用Zero-P和钛板并Cage行颈前路椎间融合术治疗外伤性颈椎椎间盘突出并脊髓损伤的临床疗效。方法回顾性分析本院2012年2月—2015年11月收治的78例外伤性颈椎椎间盘突出并脊髓损伤患者临床资料。其中38例行前路椎间盘切除、钛板并Cage内固定融合(Cage组),40例应用Zero-P行颈前路椎间融合术(Zero-P组)。比较2组患者术前及术后随访期间Frankel分级、颈椎曲度、椎间融合率、吞咽困难发生率等情况。结果所有患者随访12~37(15.76±3.80)个月。2组患者术后Frankel分级均较术前明显改善,差异有统计学意义(P0.05)。2组术后颈椎曲度均较术前明显改善,与术前相比差异有统计学意义(P0.05),且至末次随访时颈椎曲度无丢失。术后3个月,Zero-P组融合率高于Cage组,吞咽困难发生率显著低于Cage组,差异有统计学意义(P0.05)。结论传统钛板并Cage内固定融合术与应用Zero-P行椎间融合术治疗外伤性颈椎椎间盘突出并脊髓损伤均可显著改善患者脊髓功能,但Zero-P具有术后早期即可获得较高融合率及术后吞咽困难发生率低的优点。
