This paper deals with the application of microbiological parameters obtained by usingAODC and SEM methods, and ~3H-thymidine incorporation into DNA method for quantitative estimation ofbacterial biomass、productivity and growth doubbing time in order to gain better understanding of the role ofmarine bacteria and their activities in Xiamen western sea waters. The results showed that in the seawatersurface, the mean value of total coliforms was 1. 3×104 cells/ml; the mean value of bacterial productionwas 10. 5×10~8 cells/(ml·h), the growth doubling time ranged from 0. 9 to 71. 3 hours.

The reverse passive hemagglutination inhibition test was used in the screening of 1000 Chinese materia medica for inhibitors of hepatitis B virus surface *** herbal drugs were commercially available and the surface antigen was from sera of hepatitis B patients.127 effec- tive drugs were obtained from the survey of which 28 were highly inhibitory (8:1),35 were mod- erately effective (4:1),and 64 mildly effective (2:1).Further experiments with varying dosages of the drug,dosages of HBsAg and duration of contact showed 10 drugs to be of optimal effect.

An external frequency doubling electro-optically Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) 473 nm blue laser was demonstrated. With absorbed pump energy of 48 mJ at 100 Hz repetition rate, about 2 mJ of 473 nm blue laser pulse energy was achieved by cascade frequency doubling. The second harmonic conversion efficiency was 64.5%, and overall optical-optical efficiency was 4.2%, respectively. The blue laser pulse width was less than 10 ns, and beam quality factor was less than 2.4.

认识系统演化的方法姜璐，王德胜，于秀彬分析系统的平衡与非平衡的两个方面不仅会加深对系统的了解，而且可以推动科学研究的发展。平衡和非平衡的很多特点是有普遍意义的，在科学研究方法论上可以指导一般的研究。（１）实际客观系统是一个统一的整体，它们都包含有平衡、非平衡两个方面的性质，我们所观察到的系统的平衡或非平衡的特点只是系统平衡与非平衡相互作用在不同时刻的表现。系统的平衡与非平衡不是一成不变的，它们会相互转化，系统的平衡与非平衡相互作用是系统演化各种形式及多种稳定存在的状态出现的原因。我们分析系统的演化，分析系统的动力学行为，就必须分析系统的平衡与非平衡的特点，而且平衡、非平衡是不可分的，必须从整体上统一认识它们。（２）人们认识系统总是从平衡开始，认识系统的平衡相互作用，再讨论系统的非平衡特点。非平衡才能使系统演化，平衡仅是非平衡的一种特殊情况。（３）系统的复杂性不仅表现在组成系统的子系统是复杂的，子系统的组成是分层次的，而且也表现在系统内相互作用平衡与非平衡是复杂的。在分析平衡性质时，要找出非平衡的部分，指出平衡的变化趋势，在分析非平衡性质时，要找出平衡部分，使问题化简，这是研究方法上平衡与非平衡的统一。（４）

作者： Kirsten H. Walen CROMOS Richmond USA

The present study presents cytogenetics/cytology of haploidization in the origin of a new, fast growing diploid, small cell-type (F-dPCs). The sequence of events was haploid groupings of the chromosomes in normal, human metaphase cells, followed by genomic doubling to homozygousdiploidy. These events were responses to DNA replication stress fromamino acid glutamine deprivation. Importantly, these homozygous cells outgrew normal fibroblasts in 2 - 3 passages—they had gained proliferative advantage (GPA), presumably from loss (LOH) of tumor suppressor genes. They were morphologically changed cells with rounded nuclei that grew in a “streaming” growth pattern and with changed form and size of mitosis, similar to some hyperplasias. The grouping of the chromosomes in metaphase cells was asymmetric with a narrow range around the median (23) (no micro-nuclei), suggesting genetic control. The root-origin of haploidization was evidenced by maternal and paternal genomes occupying separate territories in metaphase cells, which assumedly permitted independent segregations of bichromatid chromosomes. In near-haploid ALL-L1 leukemia the loss of virtually, whole chromosomal complements was judged by SNP array analyses, as a primary event before genomic doubling to hyperdiploidy with LOH. From the present data such specific, non-random loss of chromosomes strongly suggested, a haploidization process capable of genomic doubling, as observed for the “birth” of the small, F-dPCs. This suggestion was supported by this type of leukemia being the L1-type, where L1 signifies small cells. The possibility now exists that a tumorigenic process can be initiated directly from diploid cells through haploid (near-haploid) distributed chromosomes in normal metaphase cells. This event followed by monosomic doublings to UPDs would lead to massive LOH and a return to para-diploidy, a frequent occurrence in many types of tumors. The present simple, cultural derivations of the extraordinary F-dPCs all

U.S. Secretary of State Antony Blinken delivered a much-anticipated speech at George Washington University on May 26."Much-anticipated"because what he said would confirm whether the Biden administration was doubling down on critical policies about China or if it was ready to open the door to China being a meaningful partner in addressing the complex challenges facing the global community.
