OBJECTIVE:To establish a method for full-length cDNA library of Xinjiang Artemisia rupestris. METHODS:Mod-ified Trizol method was adopted to extract total RNA in young leaves of A. rupestris,it was transcribed into single-strand cDNA, and then synthesized into double-strand cDNA by long-distance polymerase chain reaction(LD-PCR)method. PCR product was di-gested by proteinase K and sfiⅠ,and then fractionated by CHROMA SPIN-400 columns. The cDNA longer than 0.4 kb were col-lected and ligated to phage λTriplE × 2,and then protein packaging was performed. Full-length cDNA library was established by SMART technology. 20 monoclonal were randomly selected from the library,and electrophoresis was used to determine the primary library titer,library capacity,recombinant positive rate and length of insert cDNA. RESULTS:The primary library titer was 1.94× 107 pfu/mL,library capacity was 0.97×107 pfu;recombinant positive rate of insert cDNA was 96% and length was 0.5-2.0 kb with an average of 0.9 kb. CONCLUSIONS:The established library is high in capacity and quality,which can provide basis for estab-lishing cDNA library of Xinjiang A. rupestris.

To ensure the quality and safety of Panax notoginseng, a method for the simultaneous determination of 10 mycotoxins in Panax notoginseng was developed using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with acetonitrile and purified by HLB multifunction cleanup column. The separation was performed on a Phenomenex Kinetex XB-C18 column by gradient elution using methanol and 5 mmol·L(-1) ammonium acetate as mobile phase. The targeted compounds were detected in MRM mode by mass spectrometry with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The linear relationships of the 10 mycotoxins were good in their respective linear ranges. The correlation coefficients (r) ranged from 0.9981 to 1.0000. The LOQs of the 10 mycotoxins were between 0.15 and 8.6 μg·kg(-1). The average recoveries ranged from 73.8% to 107.0% with relative standard deviations (RSDs) of 0.10%-10.9%. The results demonstrated that the proposed method was sensitive and accurate, and suitable for the mycotoxins quantification in Panax notoginseng.

Calcineurin inhibitors (CNIs) are playing an important role in preventing acute rejection in renal transplantation; however, their nephrotoxicity may impact long-term renal allograft survival. Several CNI-sparing regimens (such as CNI-avoidance or CNI-minimization) have shown at least comparable efficacy with standard-dose CNI regimens. Research continues to achieve the "best" balance between efficacy and toxicity of available immunosuppressive regimens.
