YMDD mutation: HBV YMDD mutation were developed in 12 lamivudine recipients, whereas the treated group had no incidence of HBV YMDD variation, there were significant difference between two groups (p=0.000). YMDD mutation resulted in increase of the mean HBVDNA levels (p=0.000), but no contribution to serum ALT diversification (p＞0.05). 2. Precore nt1896 mutation: Precore nt1896 mutation incidence had no difference between lamivudine recipients and objects who received combination therapy of Kidney-invigorating Granule and Marine Injection, and patients of HBeAg negative and HBeAg positive had a close incidence of precore mutation as well as. Precore nt1896 mutation had no influence on serum ALT level. The occurrence of precore nt1896 mutation contributed to serum HBVDNA load increased and worse response of HBVDNA extenuation. 3. HBV genotype: The baseline of serum HBVDNA gradually increase in turn of genotype B, genotype C and genotype B/C. Genotype B seemed to obtain higher rate of serum HBVDNA loss and HBeAg/anti-HBe seroconversion after combination therapy of Kidney-invigorating Granule and Marine Injection, differencing with lamivudine therapy.

疗效相关因素研究：1YMDD变异：对照组有12例检出YMDD变异，治疗组无1例检出，两组比较有显著性差异（P=0.000）；发生YMDD变异者血清HBVDNA和ALT水平均有所升高，HBVDNA平均水平高于非变异者（P=0.000）；血清ALT与非变异者无明显差异（P＞0.05）。2前C区nt1896变异：前C区nt1896变异发生率在治疗组和对照组以及HBeAg阴性和HBeAg阳性患者之间均无明显差异（P＞0.05）；1896c变异对血清ALT水平无明显影响；治疗组发生1896c变异者，其HBVDNA平均水平较之未变异者明显升高（P＜0.05），治疗后HBVDNA下降幅度明显低于未发生1896c变异者（P=0.000）。3HBV基因型：血清HBVDNA基础水平在B、C、B/C混合型间存在明显差异（P＜0.05），按B型、C型、B/C混合型依次升高；治疗组HBVDNA阴转率、HBeAg/抗-HBe血清转换率，B型似乎高于C型和B/C混合型，但无统计学意义（P＞0.05）；对照组HBVDNA阴转、HBeAg/抗-HBe改变在B、C、B/C混合型间无明显差异（P＞0.05）。

Using ST1KO mice, we have demonstrated that early B lymphopoiesis is impaired in the absence of STAT1, including reduced numbers of pro-B, pre-B, immature-B, and mature-B cells in BM. Interestingly, B220+CD138+ cells of ST1KO mice are also significantly decreased in BM as apposed to WT mice.

在本论文中，我们发现STAT1基因剔除小鼠的早期B淋巴球发育，不论在pro-B， pre-B， immature-B，或mature-B时期皆有明显的缺陷；特别的是，STAT1基因剔除小鼠的骨髓细胞(B220+CD138+)则有明显减少的现象。

The three groups were loaded and analyzed under the same loading according to the mean value of the bite force of incisors. RESULTS:(1)The maximum stress of dentin in group A was twice higher than that in group B. The maximum primary stress, minimum primary stress and maximum shear stress of group A were respectively 236.35, 228.83 and 218.05 percent of those in group B. The difference of maximum stress values of group B and group C was neglectable.(2) The maximum stress distribution of dentin in group A and group B was quite different (the stress was concentrated in labial and lingual side of the cervical dentin in group A, otherwise in group B it was concentrated in the area around the alveolar and the labial and lingual side of the dentin which was opposite to the tip of the cast metal post and core). The maximum stress distribution of dentin in group A and group B was almost the same.

Results The UV-B treatment caused the declines of chlorophyll content, soluble protein content and water content of leaves, besides, dose-effect was existed. The decline of 30 μW/cm^2 treatment was bigger than that of 15 μW/cm^2 treatment. The influences of UV-B radiation on carotenoid content and anthocyanidin content were similar; the change trends were declined firstly then increased. The UV-B treatment with two doses restrained the electron transport of PSⅡ, particularly; the inhibitory effect was biggest after treated 2h, and then this effect was declined in 4, 6 and 8 h, so the dose-effect was existed. The UV-B radiation with two doses restricted photosynthetic rate and the inhibitory effect increased with the increase of treatment time. The high dose treatment caused huge damage to membrane system, while the result of low dose treatment was not obvious.

The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5. The borate structure and semipolar bond were studied in different pH by infrared spectrum .It indicated that N_xB and N_xOB have not semipolar bond at pH

4、25℃，N_xB系列都有较低的表面张力，并随碳原子数的增加而最低表面张力下降。N_(12)B比同碳原子数的十二烷基苯磺酸钠的最低表面张力34.5mN／m低，且临界胶束浓度为4.1×10~(-5)mol／L，也比LAS低，且随着NaCl浓度的增加而略有下降，比较N_(12)B和N_(16)B，由于C_(16)疏水基的异构体使N_(12)B的临界胶束浓度和临界胶束浓度时的表面张力γ_(cmc都低，由于增加了亲水基团使得N_(12)OB和N_(16)OB的表面张力和临界胶束浓度都要高于N_(12)B和N_(16)B。

The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas. Using above measurements, we can concluded that PS-b-PNIPAM-b-PDMA triblock copolymer micelles have the double phase transition behavior, while PS-b-PDMA-b-PNIPAM have only one phase transition behavior.2. We synthesized poly(ethylene glycol-b-methacrylic acid)diblock copolymers with three different polymerization degree of PMAA blocks.

但是对于PS-b-PDMA-b-PNIPAM胶束，由于中间亲水嵌段的作用，使PNIPAM的相转变温度提高，且PDMA由于靠近PS内核以及随着外壳PNIPAM的水溶性变差其相转变点降低，因此我们只能看到一个转变过程。2、通过原子转移自由基聚合，我们合成了三种不同PtBMA长度的PEG-b-PtBMA二嵌段聚合物，将叔丁基水解后得到了三种PEG-b-PMAA二嵌段聚合物。

Repurchase of B share is the key of study and discussion.The author thinkthat securities repurchase has been an convention of international capitalmarket and that B share public enterprises should be allowed to repurchasetheir shares according to the adjustment of their capital requirement in order touphold share price and the image of enterprises.The sixth chapter,thedemerger of A Share and B Share,proposes the demerger of the equity of anenterprise which has issued both B share and A share under special conditions,in the situation that the phenomena of different prices for the same equity isdeteriorating,and the tentative plan to set up one pure B-share publicenterprise and one A-share enterprise.In the end,this chapter demonstratesthe feasibility from the view of law and finance.

而B股回购是目前研究和争论的焦点，笔者认为，证券回购已成为国际资本市场上通行的惯例，应当允许符合条件的B股上市公司根据公司资本结构调整需要，维护股价和公司市场形象等原因进行B股回购；第六章A、B股分立，针对目前A、B股同股不同价现象日益严重，特提出有条件的A、B股上市公司进行股权分立，成立纯粹的A股上市公司和B股上市公司的设想，并从法律、财务等方面进行论证。

The contributions ofΨp from the pion and the kaon meson, the contribution ofΨB from B meson are not very small, and can not be safely neglected for giving more resonable results of form factors.The B meson wavefunction is a major source of uncertainty in the study of B meson decays. The B→πand B→K transition form factors provide a good platform to determine the possible regions for the two typical phenomenological parametersΛandδ.

但π、K介子波函数中的Ψp和B介子波函数中的ΨB对形状因子的贡献比较大，为了获得更加合理的形状因子的结果，一般不能忽略π、K介子波函数中的Ψp和B介子波函数中的ΨB项的贡献。B介子波函数是B介子衰变中不确定性的一个主要的来源。B→π和B→K跃迁形状因子为确定两个典型的唯象参数Λ和δ提供了一个很好的平台。
