活血陪元法治疗对艾滋病患者T淋巴细胞功能的影响

目的研究活血培元法治疗对艾滋病患者T淋巴细胞功能的影响.方法筛选已经开始服用抗逆转录病毒药物的HIV/AIDS成年患者24例,且病毒载量＜500 copies/ml,随机分成两组,一组加用东研Ⅰ号颗粒(中成药)和安慰剂对照,观察患者0、12、24w后的临床症状体征、T淋巴细胞亚群、血清HIV病毒载量以及细胞因子(IL-2、IL-4、IL-10、INF-γ)的变化.结果分析中药组与对照组0、12、24w后症状体征积分两组存在明显差异(P＜0.05);T细胞亚群CD4+T细胞绝对计数也有明显差异(P＜0.05);细胞因子两组均无明显差异(P＞0.05).两组病毒载量始终均为＜500 copies/ml.结论中药活血陪元法(东研Ⅰ号颗粒)能有效改善HIV/AIDS患者的临床症状及体征,提高患者的CD4+T细胞绝对计数,协助抗逆转录病毒药物控制病毒载量,但未发现对患者T细胞功能的部分细胞因子有显著影响.     

网络会计的发展与会计假设理论的松动

网络会计的发展彻底改变了实现会计目标的手段和途径,同时对会计工作的基本前提——会计假设理论也产生了巨大冲击,会计环境的这一改变要求必须对会计假设理论重新认识和界定。

《春天,遂想起》中的家园意识

余光中的《春天,遂想起》是一首有名的乡愁诗,从中我们不但可以读出融乡情、爱情、亲情、爱国情于一体的浓重的乡愁,而且站在现代社会浮躁、无根的精神世界,还可以读出“江南”、“表妹”、“母亲”等意象背后淡淡的家园意识,这是这首诗在现代广泛流传的深层原因。     

Samples Selection for Artificial Neural Network Training in Preliminary Structural Design

An artificial neural network (ANN) is applied in the preliminary structural design of reticulated shells. Major efforts are made to enhance the generalization ability of networks through well-selected training samples. Number-theoretic methods (NTMs) are adopted to generate samples with low discrepancy, i.e.uniformly scattered in the domain, where discrepancy is a quantitative measurement of the uniformity. The discrepancy of the NTM-based sample set is 1/6-1/7 that of samples with equal spacing. In a case study,networks trained by NTM-based samples are compared with those trained by equal-spaced samples in generalizing performance. The results show that both the computational precision and stability of the former ANNs are more satisfactory than those of the latter. It is concluded that the flexibility of ANNs in generalizing can be effectively increased by use of uniformly distributed training samples rather than simply piling data.More reliable uniformity should be obtained, however, through NTMs instead of equal-spaced samples.

Mathematical model of the identical slope surface

The formation of the identical slope surface and the method of construction are discussed. On the basement of building the parameter equation of variable-radius circle family envelope, the frequently used parameter equation of the identical slope surface of the top of taper moving along column helix, horizental arc and line is built. The equation can be used to construct the identical slope surface’s contours, gradient lines and three dimensional figures correctly.
