To study the expression, purification and bioactivity of human augmenter of liver regeneration in Pichia Pastoris, the expression plasmid pPICZαA- ALR was constructed and transformed into P. Pastoris by the method of electroporation transformation. Induced with 0.5% methanol, the 30 kD protein in the culture supernatant of recombinant P. Pastoris was confirmed to be rhALR by SDS-PAGE and Western blot. Quantitative analysis showed that the target protein was in a level of 66% of the total protein of the culture supernatant, with a yield of 40mg/L.we had performed DEAE anion exchange chromatography two times with excessive and regular adsorption quantity consecutively, and then the rhALR above 95% purity and 52% protein recovery could be obtained by G75 molecular sieve chromatography at last step. The bioactivity assay of the purified product showed that rhALR could stimulate the proliferation of HepG2, SMMC-7721 and NIH-3T3 in vitro.

Corbicula fluminea (Müller 1774) was bred in the laboratory and two shell samples (shell height, A=13 mm, B=9 mm) were selected to determine the carbon isotopic composition of the increment shells (aragonite, CaCO3) and the host water. The results indicate that the carbon isotopic compositions of the two shells increased as the δ^13 C values of the host water increased from -5.24‰ to 1.41‰, showing the influence of δ^13C values on the shell carbon isotopes.δ^13C value ranges from -4.76% to -2.09% and δ^13 C from -8.49% to -2.89%. The δ^13 C values of shells A and B are both more negative than the predicted equilibrium ones, indicating that the shell had used the metabolic CO2 rich in 12C during their growth process.

The call developmental process of Psittacula agapornis consists of five instinct phases according to its call character. In the first phase (congenital cal1 phase, CCP, 0~12 day of age), the juveniles only produce single syllable with short syllable length. The second phase(blank-model-forming phase,BMFP, 13~30 day of age) is important for formation of vocal learning pathways. During this phase, the calls characterized by more and longer syllables. In the third phase (call-model-forming phase,CMFP, 31~45 day of age), the call development is guided by a model system for vocal learning, vocal learning is engendered so that some calls with multi-syllables with UP1 are produced, principal frequency has increased about by 920 cent, the number of note is double that of second phase. The short-term memories are transformed into long-term memories in the forth phase (call-feedback-learning phase,CFLP, 46~90 day of age). The call of juveniles is a close match to tutor call which accompanied by double various sounds with BS and UP1, and more resonance components were formed. Second principal frequency has increased about by 970 cent, the number of note increases by 2.6~3.0 times. During the fifth phase (excellent call phase,ECP, after 91 d), vocal motor pathway is developed and the calls are accompanied with most stable, harmonious vari-tone and complex repertoire.

Transcriptional activity of ACL recombinants normalized by Renilla was significant difference with pGL3-Basic expect for construct -27 and -15 (P<0.01). Construct -919 contains highest activity. 3 times reduction of transcriptional activity from-919 to -679bp indicated that negative regulation factors located probably in this region. The activity started on construct -73 suggested the basal promoter activity was located within the -73 to +77bp region; Transcriptional activity of IDHβrecombinants was not significantly different between the recombinant -58 and pGL3-Basic. The activity started on construct -82, decreasing with the length of the fragment up to -164 in despite of a bit of fluctuation, and kept increasing from construct -164 up to -279. Thus, the basal promoter activity was located within the -82 to +16bp region, whereas the upstream 197bp conferred maximal transcriptional activity.
