Proximal gradient algorithms are popularly implemented to achieve convex optimization with nonsmooth regularization. Obtaining the exact solution of the proximal operator for nonsmooth regularization is challenging because errors exist in the computation of the gradient; consequently, the design and application of inexact proximal gradient algorithms have attracted considerable attention from researchers. This paper proposes computationally efficient basic and inexact proximal gradient descent algorithms with random reshuffling. The proposed stochastic algorithms take randomly reshuffled data to perform successive gradient descents and implement only one proximal operator after all data pass through. We prove the convergence results of the proposed proximal gradient algorithms under the sampling-without-replacement reshuffling *** computational errors exist in gradients and proximal operations, the proposed inexact proximal gradient algorithms can converge to an optimal solution neighborhood. Finally, we apply the proposed algorithms to compressed sensing and compare their efficiency with some popular algorithms.

目的探讨学龄前儿童微量元素及营养摄入对身高体重的影响。方法选取2013年9月—2014年9月期间入学衢江区300例不同幼儿园的学龄前儿童作为研究对象,并指导学校老师及家长记录每个学生连续3 d的膳食摄入情况,按儿童食欲及主食摄入量分为过量组、良好组、中等组及低下组,各75例。随访儿童12个月间的饮食状况,比较各组间生长发育情况,并分析身高体重与营养物质及微量元素的相关性。结果各组完成随访并符合最终入组研究的儿童例数分别为48例、56例、57例及47例。良好组儿童12个月后身高及身高增量均高于其他各组(P0.05),但均高于低下组(P<0.05)。而过量组12个月后体重及体重增量均高于其他各组(P<0.05),良好组及中等组的体重增量均高于低下组(P<0.05)。身高、体重与蛋白质、热能、钙、铁、锌的摄入量呈显著正相关(P<0.05),且钙、铁、锌等摄入量与蛋白质及热量的摄入呈正相关(P<0.05)。结论学龄前儿童的微量元素及营养的合理摄入对其自身的生长发育有着积极的作用,营养摄入不足或过剩均对其身高增长有着负面影响,应针对不同儿童的营养缺乏情况制定个体化方案进行干预。

Aim To investigate the effects and the mechanisms of NG-nitro-L-arginine(L-NA) on pulmonary in- flammatory cytokine expression and Nuclear Factor-κB signal pathway in a model of lipopolysaccharide(LPS) induced acute lung *** Models of ALI were induced by injection(iv) with LPS 5 mg·kg in male Sprague-Dawley(SD) ***-eight adult male SD rats weighing 220～270 g were randomly divided into 3 groups:group control,group LPS and group *** rats in every groups were further divided into two subgroups according to the L-NA-supplemented time:(3 h+3 h) group and(6 h+3 h) group.L-NA(20 mg·kg,ip) or saline(control group and LPS group) was administrated at 3 h or 6 h after LPS injection *** treatment lasted for 3 h,and the rats were sacrificed at 6 h or 9h after saline(control) or LPS *** translocation of NF-κB and the expression of intercellular adhesion molecule-1(ICAM-1) in lung tissue were respectively detected with immunohistochemisexpression(IHC);the concentrations of TNF-αand IL-6 in lung tissue were respectively evaluated by radioimmunoassay;the pathological changes of lung tissue were observed by light and electron microscope. Results Compared with that of the control group,NF-κB was significantly translocated from the cytoplasm into the nucleus,the expression of NF-κB and ICAM-1 protein were significantly increased,the concentrations of TNF-αand IL-6 in lung tissue were significantly increased in LPS group *** with LPS group, treatment with L-NA at 3 h after LPS significantly decreased the the expression of NF-κB and ICAM-1 protein, and the lung damage was alleviated in L-NA(3 h+3 h) *** concentrations of TNF-αand IL-6 in lung tissue showed no significant difference between LPS group and L-NA *** Administration of L-NA at 3 h after LPS might protect lung from LPS-induced injury by inhibiting NF-κB activation subsequently inhibiting the NF-κB-mediated nuclear factor-κB signal pathway.
