This study reviews all South China Sea species belonging to the families Rathkeidae and Zancleopsidae. Morphological characters of Lizzia blondina Forbes, 1848 （formerly recorded as Podocoryne/Hydractinia minuta）, L. gracilis （Mayer, 1900）, L. octostyla （Haeckel, 1879） and Podocorynoides minima （Trinci, 1903）（formerly recorded as Podocoryne/ Hydractinia minima） are redescribed. One new species, Zancleopsis oblongus Xu, Huang ＆ Wang, sp. nov. from South China Sea, is described and illustrated. The keys to all medusa genera of Rathkeidae and Zancleopsidae and to all species of Zancleopsis are presented. The type specimen is deposited in the Third Institute of Oceanography, State Oceanic Administration, China.

An astroglial cell line was established from the brain of half smooth tongue sole （Cynoglossus semilaevis） and was designated as CSAC. CSAC shows the morphological homogeneity of epithelial cells. The cell identity was tested by the presence of glial fibrillary acidic protein （GFAP）, which was revealed by RT-PCR and immunofluorescence. The cell line was optimally maintained at 24 ℃ in minimum essential medium supplemented with HEPES, antibiotics, 20% fetal bovine serum, 2- Mercaptoethanol （2-Me） and basic fibroblast growth factor. Chromosome analysis revealed that the CSAC cells maintained a normal diploid chromosome number （2n=42）. The fluorescent signals were observed in CSAC after the cells were transfected with green fluorescent protein （GFP） reporter plasmids. The CSAC cell line may serve as a valuable tool for studies on the potential functions of fish astroglial cells.

A series of direct numerical simulations of the fully developed plane Couette flow at a Reynolds number of 6000（based on the relative wall speed and half the channel height h） with different streamwise and spanwise lengths are conducted to investigate the effects of the computational box sizes on the secondary flow（SF）. Our focuses are the number of counter-rotating vortex pairs and its relationship to the statistics of the mean flow and the SF in the small and moderate computational box sizes. Our results show that the number of vortex pairs is sensitive to the computational box size, and so are the slope parameter, the rate of the turbulent kinetic energy contributed by the SF, and the ratio of the kinetic energy of the SF to the total kinetic energy. However, the averaged spanwise width of each counter-rotating vortex pair in the plane Couette flow is found, for the first time, within 4（1 ± 0.25）h despite the domain sizes.

钦州湾是广西最大的海湾,有丰富的港口资源,是广西海洋产业发展主要支柱区域之一。近年来的开发建设活动,加强了人为地质作用,地质环境问题越来越复杂,发展给环境带来了越来越大的压力。2006—2010年,中国地质调查局广州海洋地质调查局在北部湾广西沿海执行"北部湾广西近岸海洋地质环境与地质灾害调查"项目,对研究区进行了地质环境及人类活动影响的调查研究。论文根据海底表层沉积物和柱状样品测试资料,分析了钦州湾海底沉积物中有害元素Hg的平面分布和垂向分布特征,表明Hg污染主要来自于船舶影响。钦州湾口门内的Hg污染小于口门外,向外海则污染逐渐降低;Hg含量愈近海底,其值愈高。通过分析,认为Hg值在海底70cm以下趋于稳定,确认约700年前开始,钦州湾受人类活动影响增加;约130年前,人类活动影响加剧。总体上,Hg测量值均低于标准值,说明钦州湾环境目前尚好,但环境已受到经济发展的影响。因此,必须加大保护环境的力度,防止污染程度加深。

Guided by TCM treatment on the basis of syndrome differentiation, the author has treated 33 cases of hysteromyoma, which are divided into stagnation of liver-qi and blood stasis (SLQBS) type, and qi-deficiency and blood stasis (QDBS) type, by acupuncture-moxibustion and Tuina. After 3 therapeutic courses, the total effective rate is 81.8%. The therapeutic effect has no close relationship with the TCM syndrome differentiation.
