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）。

Methods1. Compared with adult female rats, aged female rats without oestrum were chosen by using RIA technology and sexual hormone was changed remarkably. Theses aged rats were divided into three groups（GNK group, HRT group and control group）. Treated them respectively with GNK, nilestriol and distilled water 3 months.

通过用阴道脱落细胞涂片检测发情周期的改变，放免法测定血清性激素的水平，与正常青年雌性大鼠比较，选择阴道脱落细胞无发情期改变，血清性激素水平有增龄性改变并且差异有显著性的老年雌性大鼠作为研究对象，分别用中药复方更年康和尼尔雌醇灌胃3个月，观察中药复方更年康对老年雌鼠的治疗作用。2。

Results14.8% of the students of vestibule school were low stress, 68.8% of the students of vestibule school were in moderate stress, 15.7% of the students of vestibule school were high stress.

结果有14.6%的学生处于低应激水平，有69.7%的学生处于中等应激水平中，有15.6%的学生处于高度应激水平；且三组之间的SCL-90各因子差异有显著性(P.01)。

The NO content and the NOS activity were down in the PIH pregnant women placenta.This showed that the ghrelin regulated the VEGF and influenced the the NO down.And the placenta angiospasm,blood pressure highten, and the PIH were caused also by this. The ghrelin,VEGF,Flt-1,NO and NOS were detected by the SP-immunochemistry, RQ-PCR,cell culture in vitro,ASODN and nitrate reductase in the normal pregnancy,PIH placenta and the cultured HUVEC antisense blocking ghrelin in vitro.

结果证实：PIH孕妇胎盘组织中Ghrelin，VEGF、Flt-1蛋白和mRNA水平下降与正常孕妇比较有显著性差异p＜0.05提示在PIH发病过程中Ghrelin可能对VEGF，Flt-1蛋白和mRNA的表达具有下调作用，进而影响胎盘血管网的形成和发育；NO含量与NOS活力水平在PIH孕妇胎盘组织中下降，提示Ghrelin可能通过下调VEGF的表达进一步影响血管舒张因子NO水平下降，进而引起胎盘血管痉挛，血压升高，最终导致PIH的发生。

Result :There was no significant difference between sexes,ages and sides.The fibrillation potential amplitude was maximum at 3 to 4 months after denervation of the posterior cricoarytenoid muscle or at 5 to 6 months after denervation of the thyroarytenoid muscle and still remained at certain level for years in some patients.Significant difference was showed in complete and incomplete nerve injuries groups,but changes of amplitude with time in incomplete nerve injuries group were small.

结果：不同性别、年龄及不同侧的纤颤电位波幅间的差异无显著性，失神经环杓后肌纤颤电位波幅均值在病程2～＜4个月时最高，而失神经甲杓肌纤颤电位波幅均值在病程4～＜6个月时最高，相当一部分患者的纤颤电位波幅晚期仍维持一定水平，并且神经完全损伤者和不完全损伤者各时间纤颤电位波幅均有显著性差异，而神经不完全损伤者各时间幅度变化小。

It was found that during all three stages, the expression levels of Dnmt1 mRNA in the epithelial cells of the pregnant mice were significantly lower than those in the pseudopregnant mice (P.05), and the level of Dnmt1 protein expression in the pregnant mice was significantly decreased as compared with that in pseudopregnant mice at the 4-cell stage.

结果 Dnmt1蛋白主要表达于上皮层；妊娠组小鼠各期Dnmt1 mRNA表达水平均显著性低于同期假孕组(P.05)，妊娠组4细胞期Dnmt1蛋白表达水平显著性低于同期假孕组(P.05)。

P. 01. The seropositive rates of HCMV-IgG were different significantly between CHD group and control group(x2=5. 76~6. 43,P. 05) at the dilute levels of 1 : 160, 1 : 320 and 1 : 640. In addition, the seropositive rates of HCMV-IgG in patients with AMI and OMI was significantly higher than in UAP and SA at the dilute level of 1 : 160 and 1 : 320; at the dilute level of 1 : 640, the seropositive rates of HCMV-IgG in AMI group was higher than in UAP and SA.
