The application of nursing intervention in the prevention of psychiatric disorder in patients after coronary artery bypass grafting / 中国实用护理杂志

Objective To discuss the effeet of nursing intervention in the prevention of psychiatric disorder in patients after coronary artery bypass grafting (CABG). Methods Patients with CABG(202 cases) were divided into the control group (100 cases) and the intervention group (102 cases).The control group received routine treatment and nursing while the intervention group was given systemic nursing intervention.The mental status was evaluated by mini-mental status examination (MMSE). Results The incidence of psychiatric disorder in the intervention group was 4 cases (3.92%),which was statistically lower than those in the control group(16 cases,16.00%). Conclusions Effective nursing intervention combined with effective treatment could prevent and control the psychiatric disorder of patients after CABG.

Cloning and Optimized Prokaryotic Expression of a pbmag-1 cDNA Fragment from Plasmodium berghei ANKA / 中国寄生虫学与寄生虫病杂志

Objective To clone and express a novel gene cDNA fragment,pbmag-1,from Plasmodium berghei ANKA strain. Methods The cDNA sequence of pbmag-1 was obtained from the GenBank of P.berghei ANKA genomic databases,with which a pair of primers was designed and RT-PCR was used to get a cDNA fragment of the gene from the parasite. The expanded cDNA 3′ fragment of the gene was obtained by 3′-RACE using the oligo dT primer and a set of specific primers. The intact cDNA 3′ fragment was cloned into a prokaryotic expressional vector and transformed into the BL21-(DE3)-RIL strain of Escherichia coli. The recombinant protein of PbMAg-1 was expressed with an optimized strategy and used to immunize mice. Results The pbmag-1 cDNA fragment obtained was 1 341 bp in length,A/T rich (73%) and with a correct 3′ end sequence. By Western blot,the anti-serum of mice immunized with the recombinant protein of PbMAg-1/GST,which was expressed as inclusion bodies,specifically recognized a band with Mr 64 000 molecule from the protein extracts of P. berghei-infected mouse erythrocytes. Conclusion The pbmag-1 cDNA sequence with intact 3′ has been obtained,which will be used for further study on its role in the immune response of P. berghei infection.
