IM To determine the incidence of hepatitis B virus (HBV) intrauterine infection and to explore the relationship between HBV viremia level of pregnant women and HBV intrauterine infection.METHODS Sixtynine pregnant women were divided into three groups. Group A, 41 HBsAg positive patients, 14 of them were HBeAg positive (group A1), and 27 HBeAg negative (group A2); Group B, 12 HBsAg negative patients, but positive for antiHBs and/or antiHBe and/or antiHBc; and Group C, 16 patients negative for all HBV markers. Blood samples of mothers were taken at delivery, samples of their infants were collected within 24 hours after birth (before injection of HBIG and HBV vaccine). All the serum samples were stored at -20℃. HBV serum markers were tested by radioimmunoassay and HBV NDA were detected by nested polymerase chain reaction.RESULTS In group C, all of 16 newborns were negative for HBsAg and HBV DNA. In group A, 7 infants were HBsAg positive (171%), and 17 (415%) were HBV DNA positive (P<005). The incidence of intrauterine HBV infection was much higher in group A1 than that in group A2 (HBsAg 429% vs 37%, HBV DNA 929% vs 148%, P<005). The incidence of HBV intrauterine infection was significantly different between high and low HBV viremia of mothers (933% vs 429%, P<005).CONCLUSION The incidence of HBV intrauterine infection is high when HBV DNA in newborns detected with nested PCR is used as a marker of HBV infection. It is related to HBV viremia level of mothers.

Studies were conducted with rice varieties developed in recent years in Liaoning Province of China as test materials. Results showed that the varieties tested could be divided into three types：（1） the high-yielding （HYV）, （2） the mediumyielding （MYV）, and （3） the low-yielding （LYV）. The panicle population was in the order of HYV〈 MYV 〈 LYV, while the grain number per panicle and seed-setting rate were just opposite. There was no significant difference in the 1 000-grain weight. Biomass was higher in HYV than in MYV and LYV, while the harvest index was higher in HYV and MYV than in LYV. Yield was inversely correlated with panicle population, but positively correlated with the grain number per panicle, seed-setting rate, the number of primary and secondary branch grains, seed density and harvest index. Yield was most closely linked with the grain number per panicle which was determined chiefly by the number of secondary branch grains and to a lesser degree by seed density and the number of primary branch grains. The seed-setting rate of the secondary branches was positively correlated with that of the whole panicle and yield. The peak value of primary branches for HYV, MYV and LYV was 12-14, 10-13 and 8-12, respectively. LYV had fewer secondary branch grains, while MYV and HYV had more. Such grains distributed mainly in the middle and lower parts of panicle axis for LYV and in the middle and upper parts for MYV and HYV.

Genetic epidemiology researches such as twin studies, family-clustering of hepatitis B virus （HBV） infection studies and ethnic difference studies have provided the evidence that host genetic factors play an important role in determining the outcome of HBV infection. The opening questions include which human genes are important in infection and how to find them. Though a number of studies have sought genetic associations between HBV infection/persistence and gene polymorphisms, the candidate gene-based approach is clearly inadequate to fully explain the genetic basis of the disease. With the advent of new genetic markers and automated genotyping, genetic mapping can be conducted extremely rapid. This approach has been successful in some infectious diseases. linkage analysis can find host genes susceptible to HBV and is of great clinical importance.

提出一种基于条件矩检验的Value-at-Risk(VaR)模型评估方法.其基本思想是如果VaR模型无设定误差,则观察到的"突破"事件是鞅过程.因此可以通过检验"突破"事件是否为鞅对VaR模型进行设定检验.采用条件矩检验方法对风险管理行业普遍使用的八种VaR模型进行回测检验,作者发现条件历史模拟法表现最好,通过了各种检验,而无条件正态分布VaR模型表现最差,没有通过任何一种检验.在风险管理实务中,作者推荐使用条件历史模拟法度量和管理金融风险.

In this study, a in vessel aerobic composting method is adopted to investigate the variation rules of various evaluation parameters （temperature, moisture content, pH, organic matter, water soluble ammonia nitrogen, water soluble nitrate nitrogen and germination index） in cocomposting of municipal sludge, kitchen waste and water hyacinth at different proportions. The results show that, in composting, the parameters of moisture content, pH, water soluble ammonia nitrogen and water soluble nitrate nitrogen demonstrate marked dynamic change rules during composting process; the temperature of three groups of compost materials rapidly rise to above 55 ~C within 96h, and last for 3 - 7d, meeting the harmless requirements, and their organic matter degradation rate excess 30%, the GI index is higher than 83%, in line with the requirements on maturity, which proves that the co-composting of municipal sludge, kitchen waste and water hyacinth can realize harmlessness and resource reutilization after composting.

以研究我国棉花期货和现货市场的动态关系为目的,基于VEC模型、Granger因果检验、脉冲响应分析和BEKK模型,对我国棉花期货和现货市场的价格发现功能和波动溢出效应进行实证分析.研究结果表明:期货价格和现货价格之间存在长期均衡关系和双向Granger引导关系.但期货市场对现货市场的引导作用更强,并且较现货市场具有更强的信息效应.此外,两个市场均存在很强的自身波动滞后效应,相互间的波动溢出效应也非常显著,但期货市场对现货市场的波动溢出效应明显大于后者对前者的波动溢出效应.
