He type of ossein in group B was mainly type Ⅰ collagen while that in group A type Ⅱ and it exhibited as a process of fiber formation in group C. The reason for why TGF-β〓 can promote ossification induced by BMP is that can promote the differentiation and proliferation of mesenchymal cells to supply more target cells for BMP, promote the differentiation and proliferation of mature osteocytes and chondrocytes, inhibit metalloproteinase to decrease the destruction of bone tissue and promote calcification of bone matrix.

GF-〓能促进BMP骨诱导作用主要因其能促进间充质细胞的分裂增殖为BMP提供丰富的靶细胞、促进成熟骨及软骨细胞的分裂增殖、促进骨细胞产生Ⅰ型胶原而抑制软骨细胞产生Ⅱ型胶原，抑制金属蛋白酶的活性以减少组织破坏、促进基质钙化等作用而使骨生成能力增加，提示它和BMP具有协同作用。

Active mechanism of RVLEAE may be that glycosides interfere the maturation of spermatozoon in the epididymis cauda.

RVLEAE有抗生育作用，作用部位主要在附睾，作用机制可能是糖苷类化合物干扰了精子在附睾的成熟。

The suboptimal thermoperiod was 15℃/25℃. 2. The fresh H. ammodendron seeds had highly germination ability, and have no dormant phenomenon; The fruiting wings had significant inhibition the germination of fresh mature seed in autumn, and fruiting wings made H. ammodendron seeds maintain dormancy, but with store time extend, the effect that fruiting wings inhibited seed germination gradually alleviate, fruiting wings didn't inhibition effect of seed germination until the next spring(in 4 month).

2梭梭新采收的去翅种子不存在休眠现象，而具有很高的萌发生活力；果翅对秋天新成熟种子的萌发有显著的抑制作用，使种子处于强迫休眠状态；果翅对种子萌发的抑制作用随着贮藏时间的推移逐渐降低，到翌年春天(4月)果翅解除对种子萌发的抑制作用。

Persicum seeds was 5℃/15℃. The suboptimal thermoperiod was 15℃/25℃. 2. The fresh H. ammodendron seeds had highly germination ability, and have no dormant phenomenon; The fruiting wings had significant inhibition the germination of fresh mature seed in autumn, and fruiting wings made H. ammodendron seeds maintain dormancy, but with store time extend, the effect that fruiting wings inhibited seed germination gradually alleviate, fruiting wings didn't inhibition effect of seed germination until the next spring(in 4 month).

Objective:in order to compare the curative effects of using lamirudine and thymosin together with using thymosin only to the paients of chronic hepatitis b.methods:we had chosen 27 medical cases of chronic hepatitis b,which were divided into two groups:15 cases asone group,and 12 cases as the other group.let group a take 100 mglamirudine orally,qd,with half a year as a period of treatment.at the same time givethe patients injections of 100 mg thymosin,qd,for a month.to group b was only takenlamirudine.alt,tbil,the indicators of the virosis of hepatitis b (hbsag,hbeag,hbv-dna)were observed as quatos.results: at the end of the treatment, the rates that groupa and group b made hbsag transform into negative were respectively 26.67% and 16.67%(p＞0.05);hbeag:33.33%,8.33%;hbv-dna:53.33%,33.33%(p＞0.05).conclusion:combining thymic peptide with 3tc to treat chronic type b hepatitis, thymic peptide will not only promote b-cell to mature and transformation, but also to keep the subpopulation of t-cell in immune system in balance, which can enhance the reaction of matured t-cell to the antigen or other stimulus.

目的：比较拉米夫定（3tc）与胸腺肽联用和单用拉米夫定治疗慢性乙型肝炎的疗效。方法：选择慢性乙型肝炎患者27例，分为联合组15例和拉米夫定组12例；联合组用拉米夫定100 mg，口服，qd，疗程半年，合并用胸腺肽100 mg，静滴，qd，疗程1个月。拉米夫定组单用拉米夫定。以谷丙转氨酶、血清胆红素、乙肝病毒标志物(hbsag，hbeag，hbv-dna)为观察指标，比较不同治疗方案对指标的影响。结果：治疗结束时联合组与拉米夫定组对慢性乙肝患者血清hbsag阴转率分别是26.67％和16.67％(p＞0.05)；hbeag阴转率分别是33.33％和8.33％(p＞0.05)；hbv-dna阴转率分别是53.33％和33.33％(p＞0.05)。结论：胸腺肽联合3tc治疗慢乙肝，胸腺肽具有促进t淋巴细胞的成熟和转化，并维持免疫系统各t淋巴细胞亚群间的平衡作用，能增强成熟t淋巴细胞对抗原或其他刺激的反应。

In addition, it must also evade immune clearance. Elimination of H. pylori by phagocytes is inefficient because H. pylori exhibits several virulence factors to evade opsonization, retard phagocytosis, and disrupt membrane trafficking and phagosome maturation after internalization of the microorganism.
