目的检测保胆取石手术前后血脂、血瘦素(Leptin)及胆囊收缩素(CCK)水平的变化,并探讨其与术后结石复发的关系。方法选取保胆取石手术患者30例作为研究组,并以同期无胆囊结石的健康患者30例作为对照组。测定研究组术前及术后血脂、Leptin及CCK水平,分析上述指标的差异,并分别与健康对照组作比较。结果保胆组患者术后血清高密度脂蛋白(HDL)低于术前水平(P=0.001),而血清总胆固醇(TC)、血清三酰甘油(TG)、低密度脂蛋白(LDL)与术前差异无统计学意义(P值分别为0.068、0.873和0.097);术后血Leptin和CCK低于术前水平(P值分别为0.000和0.000)。保胆组患者术前血TG高于正常对照组(P=0.025),而TC、LDL和HDL与正常组差异无统计学意义(P值分别为0.842、0.846和0.330);保胆组患者术前血Leptin和CCK高于正常对照组(P值分别为0.002和0.000)。保胆组患者术后血TG高于正常对照组(P=0.009),HDL低于正常对照组(P=0.000),而TC与LDL差异无统计学意义(P值为0.312和0.384);术后患者血Leptin与正常对照组差异无统计学意义(P=0.953),血CCK仍高于对照组,差异具有统计学意义(P=0.005)。结论保胆取石术后血Leptin和血CCK水平较术前明显降低,对于预防术后结石复发具有重要意义;术后血HDL较术前明显降低,而TC、TG和LDL无明显改变,说明保胆术后低脂饮食和增加适当锻炼,仍是预防结石复发的重要手段。

基于小核能量一致性相对论赝势,采用密度泛函理论和耦合簇理论,分别在标量和二分量水平上计算研究了MH_(2)(M=Zn,Cd,Hg,Cn)分子的平衡键长和振动频率.计算结果显示,HgH_(2)和CnH_(2)的自旋轨道耦合效应较为明显.采用的8种泛函总体较好地评估了自旋轨道耦合效应.耦合簇理论计算的ZnH_(2)、CdH_(2)、HgH_(2)的键长和Σ_(u)振动频率与实验值偏差略大,这可能是由于其多参考态特性较明显.二分量PBE泛函计算的键长和Σ_(u)振动频率与实验值最接近.目前最重的CnH_(2)相关研究未见报道,研究给出了其键长和振动频率的理论值.

If the glowworm individual has no memory during its movement, and the decision of next direction is limited to its current position. It is precisely these reasons mentioned above that make the basic Glowworm Swarm Optimization easy to trap into the local optimum. In order to solve the problem, this paper suggests a Shuffled mutation glowworm swarm optimization(SMGSO), which combines the thought of Shuffled Frog Leaping with Glowworm Swarm Optimization. Making use of a grouping idea of Shuffled Mutation, the glowworm swarm is divided into several subgroups. The location updating of each individual is not only influenced by the brightest node in neighbour scope, but also by the brightest one in their local subgroup, meanwhile the locations of those isolated nodes are updated by the difference mutation of the global optimum and local optimal. In group shuffling stage, an orthogonal strategy can guide the whole population to generate their offspring. The performance of this proposed approach is examined by well-known10 benchmark functions, and its obtained results are compared with what other variants hold. The experimental analysis show that the Shuffled mutation glowworm swarm optimization is effective and outperforms other variants in terms of solving multi-modal function optimization problems, and the proposed approach can improve the positioning accuracy of the centroid localization.

A computational fluid dynamics （CFD） model is used to investigate the hydrodynamics of a gas-solid fluidized bed with two vertical jets. Sand particles with a density of 2660 kg/m3 and a diameter of 5.0 × 10^-4 m are employed as the solid phase. Numerical computation is carried out in a 0.57 m ×1.00 m two-dimensional bed using a commercial CFD code, CFX 4.4, together with user-defined Fortran subroutines. The applicability of the CFD model is validated by predicting the bed pressure drop in a bubbling fluidized bed, and the jet detachment time and equivalent bubble diameter in a fluidized bed with a single jet. Subsequently, the model is used to explore the hydrodynamics of two vertical jets in a fluidized bed. The computational results reveal three flow patterns, isolated, merged and transitional jets, depending on the nozzle separation distance and jet gas velocity and influencing significantly the solid circulation pattern. The jet penetration depth is found to increase with increasing jet gas velocity, and can be predicted reasonably well by the correlations of Hong et al. （2003） for isolated jets and of Yang and Keairns （1979） for interacting jets.
