Chinese Traditional and Herbal Drugs 2013;44(6):749-754
Objective: To analyze the expression of terpene synthases of Aquilaria sinensis, an endangered south medicine, and to predict the influences of the environmental factors and stresses on the synthesis of terpene in A. sinensis. Methods: Two-year old seedlings and calli were treated by different stresses. The gene expression patterns of terpene synthases were analyzed by real-time qPCR. Results: Wounding and cauterizing could induce the transcriptional expression of terpene synthases in the stems, and the effect of cauterizing was more significant. Low temperature inhibited the transcription of terpene synthases. In calli, methyl jasmonate (MeJA) treatment had the most effective induction. Conclusion: Both wounding and cauterizing could induce the synthesis of terpenes in stems, while the cauterizing treatment might have better effect. Low temperature has negative influence on agarwood formation. For calli, different treatments could induce the terpene synthesis, while MeJA has the best efficacy.

OBJECTIVETo explore the conversion rule of serological blood group and blood group substance after successful allogeneic hematopoietic stem cell transplantation, and to provide theory for clinical special blood type identification and blood transfusion.
METHODSThe growth cycle of recipient WBC and RBC, RBC chimera, blood group antibody production and remaining in full transition were observed. Conversion rule of blood group substance, contradiction between cells typing and sera typing were detected by saline medium tube method and microcolumn gel method after stem cells transplantation.
RESULTSThe average time of engraftment in 21 recipients was about 18.6 days, RBC growth cycle in 8 major blood type incompatibility was 56.6 days, 25.9 days in 9 minor blood type incompatibility, 67 days in 4 bidirectional blood type incompatibility (P < 0.01). The ratio of RBC chimeric growth was 1:9, gradually converse to donor's blood group. Residue of recipient anti-A(B) was left after conditioning regimen, disappeared after full transformation, and recipient anti-A(B) was converse to donor's blood type in major blood type incompatibility. 5 A blood type recipient donated by O blood type blood generated anti-B instead of anti-A, 3 B blood type recipient generated only anti-A instead of B in minor blood type incompatibility, and 1 AB blood type recipient donated by A did not generate anti-B. Among 4 bidirectional blood type incompatibility, 2 B blood type recipient donated by A blood type blood did not generate anti-B, 2 A recipient by B could not produce anti-A. Recipient blood group substance helped original ABO blood type substance remain unchanged.
CONCLUSIONAmong patient with allogeneic hematopoietic stem cell transplantation, recipient's ABO and RBC blood type can be converse to donor's, but there is significant difference between patients of serological blood group and of normal people (P < 0.01). Recipient blood group substance helps original ABO blood type substance remain unchanged (P > 0.01).
