目的:研究红花-甘草配伍对寒凝血瘀模型大鼠血浆及脑组织中三磷酸腺苷(ATP)、二磷酸腺苷(ADP)、一磷酸腺苷(AMP)及能荷(EC)水平的影响,从能量代谢角度探讨该配伍对寒凝血瘀证的影响.方法:采用冷水冰浴方法成功建立寒凝血瘀证SD大鼠模型,将造模成功大鼠随机分为4组,即模型对照组、红花组、甘草组、红花-甘草组,另设正常对照组.造模成功后,给药组灌胃相应的药物,剂量为20 g·kg-1,模型对照组和正常对照组给予等容积的纯净水,各组均连续灌胃15 d,检测大鼠血浆及脑组织中3种腺苷酸的含量并计算能荷值.结果:与正常对照组相比,模型对照组ATP、ADP的含量及EC值均显著降低(P＜0.01),AMP的含量降低不明显.与模型对照组相比,各给药组ATP、ADP的含量及EC值均显著升高,红花-甘草组改善上述指标的作用强于单药组,差异有显著性(P＜0.05).结论:红花和甘草均可改善寒凝血瘀模型大鼠的能量代谢,促进机体对能量物质的利用,红花-甘草配伍对改善寒凝血瘀证能量代谢显示出更佳的疗效.

Objective To investigate the effect of Lactobacillus casei on depressive behavior and the expression of NR1, NR2A receptor in postpartum depression rats induced by maternal separation. Methods Twenty-four Sprague-Dawley female rats were randomly divided into control group( CON group) (n=8),postpartum depression group(PPD group) (n=8),postpartum depression with lactobacillus casei group(PPD+ Lactobacillus casei group) (n=8). Rats of the control group were given no interventions. Rats in PPD group and PPD+Lactobacillus casei group were given maternal separation to establish depression model. And then the rats in PPD+Lactobacillus casei group were treated with Lactobacillus casei ( 8× 108CFU/(kg·d)) for 4 weeks after 14 days of maternal separation. The forced swimming test ( FST) was employed to detect the depressive behaviors. Lactobacillus,Bifidobacterium,Enterococcus faecalis and Esche-richia coli in cecum of rats and the expression of NR1 and NR2A mRNA in hippocampus of rats were detec-ted by real-time fluorescence quantitative PCR. Results Compared with CON group ((157. 50±8. 13) s), the immobility time of PPD group((200. 00±10. 35) s) was significantly longer (t=-3. 23,P<0. 05). Com-pared with PPD group,the immobility time of PPD+ Lactobacillus casei group ((153. 25±7. 41) s) was sig-nificantly shortened (t=3. 67,P<0. 05),and the depressive behavior was improved. Compared with CON group,the mRNA expression of Lactobacillus ((1. 47± 0. 08),t=-5. 87,P<0. 01),Enterococcus faecalis ((1. 23±0. 08),t=-2. 85,P<0. 05) and Escherichia coli( (1. 33±0. 07),t=-4. 96,P<0. 01) in caecum were significantly increased in PPD group, while that of Bifidobacterium decreased significantly (( 0. 65 ± 0. 07),t=5. 18,P<0. 01). Compared with PPD group,the mRNA expression of Lactobacillus ( ( 1. 05 ± 0. 05),t=3. 67,P<0. 01),Enterococcus faecalis ((0. 97±0. 05),t=2. 74,P<0. 05) and Escherichia coli ((1. 06±0. 05),t=3. 31,P<0. 01) were significantly decreased in PPD+ Lactobacillus casei group,while that of Bifidobacterium increased significantly ((0. 98± 0. 04),t=-4. 26,P<0. 01). Compared with CON group,the mRNA expression of NR1 receptor (( 0. 57 ± 0. 04), t=9. 65, P<0. 01) and NR2A receptor ((0. 60±0. 05),t=8. 64,P<0. 05) in hippocampus of rats in PPD group were significantly decreased. Com-pared with PPD group,the expression of NR1 receptor ((1. 01±0. 05),t=-5. 39,P<0. 01) and NR2A re-ceptor ((0. 98±0. 07),t=-3. 91,P<0. 05) in hippocampus were increased significantly in PPD+ Lactoba-cillus casei group. Conclusion Lactobacillus casei can improve the depressive behavior of postpartum depression in rats,and improve the intestinal flora,which affect the expression of NR1 and NR2A in hippocampus.
