ObjectiveTo investigated the effects of Rhodiola Compound on improving the intellective function in mice and provide the basis for clinical application.MethodsMice were divided to different groups of three doses of rhodiola compound (0.3 g/kg,0.6 g/kg,1.2 g/kg) and swimming abilities were tested.Other mice were administrated single dose of compound rhodiola( 1.2 g/kg) and training by Morris water maze.Drug's improving intelligence function was assessed using memory acquisition impaired models made by scopolamine or alcohol.When the Morris water maze test was finished,mice were killed and brains were removed immediately to measure SOD and NO levels.ResultsGroups of three doses of compound rhodiola could significantly prolong the swimming time(P ＜ 0.05,P ＜ 0.01 ).Compound Rhodiola group can significantly reduce the swimming distance than the untreated group( ethanol model group:(26 906.6 ± 2769.7 ) mm,RCE treated group:( 19 586.1 ± 6826.7 ) mm ; P ＜0.05 ).Swimming distance and time of cross-platform quadrant was significantly increased,comparing with model group (P ＜ 0.05 ).Compound Rhodiola significantly enhanced the activity of mouse brain's SOD ( Scopolamine model group:( 150.3 ± 17.7 ) U/ml,RCE treated group:( 197.9 ± 16.8 ) U/ml ; P ＜ 0.05 ) and NO levels ( Scopolamine model group:( 44.7 ± 16.7 ) μmol/gprot,RCE treated group:( 65.4 ± 14.5 ) μmol/gprot ; P ＜ 0.05 ) significantly.ConclusionCompound Rhodiola could promote mice learning and memory function,SOD and NO in brain maybe play a important role in this effect.

【Objective】 To report the antibody specific identification process of a pregnant woman who had no history of blood transfusion but presented high-frequency anti-Jr^a antibodies. 【Methods】 Antibody screening and identification were performed by saline and indirect Coomb’s technique (microcolumn gel card, PEG). ABO, Rh and other blood group antigens were identified by saline. Further antibody identification tests were performed by the reaction between cells treated with various enzymes and patient plasma. Jr^a antigen was identified by human anti-Jr^a antibody. JR blood type genotyping was performed by MALDI-TOF mass spectrometry detection system. Antibody titer in serum was tested. 【Results】 The patient′s blood type was O with RhD(+ ) and CcDEe. The plasma reacted negatively with antibody screening and identification cells by saline, but positively by indirect globulin test. The self-control was negative. The patient′s Jr^a antigen was negative in serological tests and mass spectrometry blood type genotyping. Mass spectrometry revealed a homozygous nonsense mutation (c.376C>T) in exon 4. The anti-Jr^a antibody titer was 1∶2. 【Conclusion】 The patient developed high-frequency anti-Jr^a antibodies during pregnancy.
