In blastula embryos and 50% epiboly embryos, the zygotic pou2 transcript is also distributed in every blastomere cell. At the stage of 90% epiboly, expression of pou2 converges to the dorsal midline of embryos and locates in two waves of lateral neural plate and two transverse stripes in the brain region. In embryos at 100% epiboly, pou2 transcript is restricted in the neural plate and areas of presumptive midbrain amid himdbrain. From somite stage, gibel carp pou2 can not be detected any more, which is consistent with the RT-PCR result.

在高囊胚期和50%下包期，高度表达的合子转录本仍在所有的胚盘细胞中，但至90%下包期时，pou2的表达向胚胎背部的正中线汇聚，集中在神经板的两侧区域和脑部的两条横向条带在100%下包期时，pou2的表达集中在神经板的中间区域以及预期形成的中后脑区域至体节期时，转录本消失，这与RT-PCR结果高度一致。

Temporal and spatial expression pattern of gibel carp pou2 during embryogenesis was investigated by RT-PCR and whole-mount in situ hybridization. RT-PCR result indicates that there is maternal transcript of gibel carp pou2 in early embryos and the zygotic pou2 transcript is abundantly expressed from blastula stage. Large amount of pou2 transcript is detected at both 50% and 90% epiboly stages. At 100% epiboly stage, however, the pou2 transcript reduces rapidly and disappears at the later embryogenesis. Whole-mount in situ hybridization shows that the maternal transcript ubiquitously exists in all blastomere cells.

我们用RT-PCR和整体原位杂交的方法研究了银鲫pou2基因在胚胎发育过程中的时空表达图式RT-PCR结果显示，银鲫pou2基因有母源转录本，其合子基因在高囊胚期强烈表达，在50%下包期和90%下包期也有高量的转录本，但在100%下包期表达量急剧降低，至体节期时已经完全检测不到其转录本胚胎整体原位杂交结果显示其母源转录本在所有的胚盘细胞中。

In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。

Results the risk for developing gestational diabetes mellitus was increasing with growth rate of pregnant body mass index (or=89.1274,95%ci6.2574～95.1757),pre-pregnancy body mass index (or=8.1826,95%ci7.1804～41.3126) years of age(or=2.4322,95%ci2.2815～15.2251) and having family history of diabetes(or=4.1254, 95%ci 4.0247～27.2024),but no statistical difference was observed in pre-pregnancy height.the faster women' s growth rate of body mass index in duration of increase pregnancy,the more possible who would fall in ill with gestational diabetes mellitus.conclusion the incidence of gestational diabetes mellitus was related to the growth rate of pregnant body mass index.

结果 多因素回归分析显示，孕期体质指数增加大(or=89.127？4，95％ci=6.257？4～95.175？7)、孕前体质指数大(or=8.182？6，95％ci=7.180？4～41.312？6)、有糖尿病家族史(or=4.125？4，95％ci=4.024？7～27.202？4)、年龄大(or=2.432？2，95％ci=2.281？5～15.225？1)均增加孕妇发生妊娠期糖尿病的风险；未发现身高与妊娠期糖尿病发病有关。排除孕前体重干扰后，孕期体重增长速度越快，发生妊娠期糖尿病的风险越大。结论孕期体质指数增长过快是妊娠期糖尿病的独立危险因素。

Can accelerate the bone marrow cell from G1 phase into S phase when we measure it's Cell cycle, it make S phase rate was increased .thus it promoted DNA synthesize and repaired. Mice irradiated at dose of 5.5 Gy gamma-irradiation showed timed-related decreases and restores in peripheral blood picture at day 1 through day 21, the counts of WBC of these group had taken drug has various degree to increase than irradiation control group in day 1. Grugs failed to protected the peripheral blood cell at lowest point, but seems promote their rescovery.9803 treated group was distinct. At 7days after mice were radiated in 3.5 Gy. we observed drug can Significantly hold back the decreased number of hematopoietic progenitors colony forming radiation induced. These findings indicated 9803 have a certain radioprotective activity against gammer irradiation in mice.

给药组的 CFU-S 数量较照射对照组明显增加，3.5Gy 照后第七天观察给药9803组对小鼠骨髓造血组细胞集落生成能力的影响，给药组的造血祖细胞集落的形成能力强于照射对照组，并且9803组明显优于523组。5.5Gy 照射引起的小鼠的外周血细胞数量的降低以 WBC 发生最早，照后24小时给药组的 WBC 数量均比照射对照组有不同程度的升高，以9803各给药组最为明显，药物未能使照射引起的外周血细胞最低值升高，而有降低的趋势，但给药对照射后期外周血象的总体恢复有较好的促进作用。7.5Gy 照射后第七天测定小鼠骨髓细胞周期的测定中发现9803具有促进骨髓细胞由 G1期进入 S 期的效应，致使 G0/G1期细胞显著减少， S 期细胞比率显著增加，这利于促进 DNA 合成修复，即促进骨髓细胞增殖，骨髓细胞 DNA 含量给药组显著高于照射对照组。

The progress of the cell cycle of Spodoptera frgiperda IPLB-Sf21-AE clonal isolate 9 (Sf9) cells was directed by Flow cytometry analysis.The results showed that the whole time of the cell cycle was about 18 hours and the gapes between every two phases were about 6 hours.At 12-18 hours post AcNPV infection,Sf9 cells were arrested in G\-2/M phase.When the cells in G\-1/S phase synchronized by druge were infected by AcNPV,2/3 of the cells was in G\-2/M phase and 1/3 of the cells in S phase.
