These ingredients includes epidermal growth factor, hepatocyte growth factor, dimethyl sulfoxide, phenobarbital sodium and all trans-retinoic acid. We isolate and culture primary 10-weeks-old human fetal hepatocytes, observe hepatocytes form and its function markers. Inoculate hepatocytes with HBV Dane particles to observe if HBV susceptibility of fetal hepatocytes can be induced in vitro. To detect HBV covalently closed circular DNA within hepatocytes, we improve the existent PCR method.

The most important factor influencing implant survival in sinus augmentation, besides individual surgical technique, is the preexisting bone height between the sinus floor and alveolar crest. The key factor for success is to achieve primary stability. When the available bone height is less than 5mm or the thickness of the cortical bone is inadequate, two stage protocol (elevating the sinus floor to create sufficient bone height first, and then placing the implant at the second stage) is a safe, predictable treatment modality.

上颚窦植牙手术的成功与否，除个人手术技巧外，常取决於剩余齿槽骨之高度(residual bone height， RBH)，如何得到初期稳定度是一重要之关键，当可利用之齿槽骨高度小於5mm或皮质骨宽度不足以支撑植体获得理想初期稳定度时，分二阶段先提高上颚窦高度再植牙，不失为一理想，安全且可预期性高之植牙方法。

As shown in the experimental results: as the conductor of petroleum biological degradation, the quantity of microorganism is the important factor of petroleum degradation efficiency, the huge natural capacity of microorganism in soil is its foundation of bioremediation; petroleum density in certain scope do not affect for the degradation efficiency of petroleum, and in the density of 5%, its initial degradation efficiency is higher, however after training 40 days, this kind of advantage change weak gradually, the reason may be the petroleum of high density probably having certain poison role for microorganism; the best ecological condition of petroleum contaminated soil bioremediation is that nutrition material C: N = 60, electron receives body HiOi joining quantity amount to 12 mg/g, water content is 50%, surface activator is anion surface activator of 12 Wan base benzene sulphur sour sodium; the relation of primary and secondary of factor is water content, surface activator, nutrition material and electron receiver.
