Public cloud computing provides a variety of services to consumersvia high-speed internet. The consumer can access these services anytimeand anywhere on a balanced service cost. Many traditional authenticationprotocols are proposed to secure public cloud computing. However, therapid development of high-speed internet and organizations’ race to developquantum computers is a nightmare for existing authentication schemes. Thesetraditional authentication protocols are based on factorization or discretelogarithm problems. As a result, traditional authentication protocols arevulnerable in the quantum computing era. Therefore, in this article, we haveproposed an authentication protocol based on the lattice technique for publiccloud computing to resist quantum attacks and prevent all known traditionalsecurity attacks. The proposed lattice-based authentication protocolis provably secure under the Real-Or-Random (ROR) model. At the sametime, the result obtained during the experiments proved that our protocol islightweight compared to the existing lattice-based authentication protocols,as listed in the performance analysis section. The comparative analysis showsthat the protocol is suitable for practical implementation in a quantum-basedenvironment.

To investigate a possible therapeutic mechanism of cell therapy in the field of cerebral palsy using granulocyte-colony stimulating factor（G-CSF）-mobilized peripheral blood mononuclear cells（m PBMCs）,we compared the expression of inflammatory cytokines and neurotrophic factors in PBMCs and m PBMCs from children with cerebral palsy to those from healthy adult donors and to cord blood mononuclear cells donated from healthy *** significant differences in expression of neurotrophic factors were found between PBMCs and m ***,in cerebral palsy children,the expression of interleukin-6 was significantly increased in m PBMCs as compared to PBMCs,and the expression of interleukin-3 was significantly decreased in m PBMCs as compared to *** healthy adults,the expression levels of both interleukin-1βand interleukin-6 were significantly increased in m PBMCs as compared to *** expression of brain-derived neurotrophic factors in m PBMC from cerebral palsy children was significantly higher than that in the cord blood or m PBMCs from healthy *** expression of G-CSF in m PBMCs from cerebral palsy children was comparable to that in the cord blood but significantly higher than that in m PBMCs from healthy *** expression of pro-inflammatory cytokines（interleukin-1β,interleukin-3,and-6）and higher expression of anti-inflammatory cytokines（interleukin-8 and interleukin-9）were observed from the cord blood and m PBMCs from cerebral palsy children rather than from healthy *** findings indicate that m PBMCs from cerebral palsy and cord blood mononuclear cells from healthy newborns have the potential to become seed cells for treatment of cerebral palsy.

背景和目的卡培他滨联合奥沙利铂方案（CapeOX）是针对转移性结直肠癌患者的细胞毒化疗备选方案之一。而S-1联合奥沙利铂双药联合方案（SOX）具有很好的发展前景。本试验旨在比较CapeOX方案与SOX方案的有效性和安全性。方法本研究属于开放、多中心随机对照的Ⅲ期临床研究,来自韩国11个研究机构参与试验。符合入组标准的患者按照1∶1的比例随机接受CapeOX（第1;4天卡培他滨1 000 mg/m2,每日2次,并且第1天奥沙利铂130 mg/m2）和SOX方案（第1;4天S-1 40 mg/m2,每日2次,并且第1天奥沙利铂130 mg/m2）治疗。两者均为3周方案,包含奥沙利铂的联合化疗共9个疗程,除非在治疗中出现疾病进展、不能耐受的毒性反应和主观拒绝治疗。完成后允许进入卡培他滨或S-1单药治疗的维持期。试验以电脑生成的随机数列进行随机分组（按以下因素进行分层:原发病变部位、既往有无接受辅助或新辅助治疗以及是否存在可测量病灶）。试验的主要终点为SOX方案相对CapeOX方案显示出非劣效无进展生存（PFS）。统计分析来自意向治疗人群。本研究已在***注册,编号为NCT00677443。结果在2008年5月14日至2009年9月23日期间,共有168名患者接受SOX治疗方案,172名患者接受CapeOX方案。两者中位PFS分别为8.5个月（95%CI:7.6-9.3）和6.7个月（6.2;.1,危险比RR=0.79,95%CI:0.60-1.04;非劣效P<0.0001,Log-rank检验P=0.09）。可信区间的上限低于预测值1.43,显示在PFS上,SOX方案劣于CapeOX方案。安全性方面,SOX组记录到3;级粒细胞减少[49（29%）vs.24（15%）]、血小板减少[37（22%）vs.11（71%）]、腹泻[16（10%）vs.7（4%）]的发生率高于CapeOX组。但CapeOX组各级的手-足综合征发生率均高于SOX组[51（31%）vs.23（14%）]。结论 SOX方案有望成为转移性结直肠癌患者可供选择的一线双药联合化疗方案。有必要进一步试验探讨联合靶向药物及其在辅助化疗中的疗效。
