Objective To analyze the relevance between the nursing students′ sense of life meaning and death attitudes. Methods 181 nursing students were surveyed with the Purpose In Life Test (PIL) and Death Attitude Profile-Revised (DAP-R), and then did the relevant statistical analysis. Results The nursing undergraduates′overall average of PIL was (91.45 ± 10.54) points, and the neutral acceptance death attitude got the highest scores which were 24.14 ± 5.78, while escape acceptance got the lowest scores which were 11.76 ± 3.61. And there was a significant negative correlation (r =-0.257, P <0.05) between the sense of life meaning and death attitudes. Conclusions There was a significant negative correlation between the sense of life meaning and death attitudes, the more sense of life meaning was, the more positive attitudes toward death would be. So it′s of great importance to provide life-and-death education to improve the nursing students′sense of life meaning and death attitudes.

Objective To construct and identify recombinant vaccine Bifwlobacterium bifidum(Bb)pGEX-Sj14-3-3 of Schistosoma japonicum(Sj). Methods Total RNA was extracted from adult Sj, antigen encoding gene Sj14-3-3 was amplified by RT-PCR and cloned into Escherichia coli (E. coli)-Bb shuttle expression vector pGEX-1λT to construct recombinant plasmid pGEX-Sj14-3-3. The recombinant plasmid was transformed into E. coli BL21 (DE3).The plasmid was extracted and identified by using BamH I and EcoR I. Then pGEX-Sjl4-3-3 was electroporated into Bb to construct recombinant Bb (pGEX-Sj14-3-3) vaccine. The extracted plasmid of the recombinant Bb (pGEX-Sj14-3-3) vaccine was identified by PCR, and the size of the products was compared with Sj14-3-3 gene of adult worms.Results Sj14-3-3 of 399 bp in length was amplified by RT-PCR. The products were digested by BamH I and EcoR I , and the fragments length of plasmid pGEX-Sj14-3-3 vector was 4947 bp, and of Sj 14-3-3 gene was 399 bp.The product of 399 bp Sj14-3-3 gene was also amplified by PCR from template of the extracted plasmid of the recombinant Bb(pGEX-Sj14-3-3 ) vaccine. The size of the product obtained was just the same as expected.Conclusion The recombinant Bb(pGEX-Sj14-3-3) vaccine of Sj is successfully constructed.

Objective To investigate the effects of recombinant vaccine Bifidobacterium bifidum (Bb) pGEX-Sj14-3-3 on splenocyte apoptosis in BALB/c mice.Methods Ninety-six BALB/c mice were randomly divided into two groups according to their body mass:per os group (PO) and intranasal immunization group (IN),with 48 mice in each group.All mice were orally and intranasally immunized with recombinant vaccine Bb(pGEX-Sj14-3-3).Four mice in each group were sacrificed on weeks 0,2,4,6,8,10,12,14,16,18,20 and 22,respectively,after immunization,and splenocytes were separated and cultured with or without ConA stimulation.The apoptotic rates of splenocytes were detected by flow cytometry.Results It showed that apoptotic level of splenocytes in both groups remarkably increased after 2-4 weeks without ConA stimulation (PO:0.069 ± 0.005,0.076 ± 0.010; IN:0.037 ± 0.002,0.075 ± 0.002),and the value reached the peak on the 4th week,and the differences were statistically significant compared with that of week 0(all P ＜ 0.05).Apoptotic level of splenocytes in both groups with ConA stimulation increased after 2-6 weeks(PO:0.089± 0.006,0.098 ± 0.010,0.060±0.007; IN:0.054 ± 0.001,0.093 ± 0.003,0.058 ± 0.012),and the value also reached the peak after 4 week,respectively.The differences were statistically significant compared with that of week 0 (all P ＜ 0.05).Apoptotic level of splenocytes in each group with ConA stimulation was significantly higher than that without ConA stimulation.Conclusion It is suspected that the recombinant vaccine Bb(pGEX-Sj14-3-3) may inhibit apoptosis of splenocytes in mice immunized orally or intranasally.

Objective To investigate the change in the expression of excitatory amino acid transporter 3 (EAAT3) in the spinal cord neurons in a rat model of chronic morphine tolerance. Methods Forty-five male SD rats were randomly divided into 5 groups ( n = 9 each) : group I sham operation (group S); group II normal saline (group NS); group Ⅰ morphine (group M); group Ⅳ ketamine (group K) and groupV M + K. In group II - V a catheter was placed in the subarachnoid space at L_(3-5) interspace. The animals were observed for 3 days. The animals with motor or sensory paralysis of the hindlimbs were excluded. NS 40 μl,morphine 20 μg, ketamine 30μg,morphine 20μg + ketamine 30μg were injected via intrathecal catheter twice a day for 7 consecutive days. 50% paw withdrawal threshold and latency (PWT, PWL) of the hindpaw to radiant heat were measured before (T_0, baseline) , on day 1, 3, 5, 7 of (T_(1-4)) and 1 day after (T_5 ) IT drug administration. The rats were sacrificed after last pain threshold measurement. The expression of EAAT3 protein in the spinal cord was determined by Western blotting and immuno-histochemistry. Results The sensitivity of the hindpaw to noxious heat stimulation was significantly decreased during (T_(1,2)) and increased after IT administration (T_(4,5)) in group M and was significantly decreased during and after FT administration (T_(1-5)) in group M + K as compared with the baseline values at T_0 and group S and was significant lower in group M + K than in group M. The expression of EAAT3 protein in the spinal cord was significantly decreased in group M and M + K as compared with group S and was significantly lower in group M than in group M + K. Conclusion The down-regulation of the expression of EAAT3 in the spinal dorsal horn neurons is involved in the development of chronic morphine tolerance and the expression of EAAT3 is down-regulated by morphine partly through the activation of NMDA receptor.
