Journal of Clinical Pediatrics 2016;34(12):936-941
Objective To explore the effect of Quercetin on the long-term memory and PARP-1/AIF signal path in neonatal rats with hypoxic-ischemic brain damage (HIBD). Methods Fifty-six 7-day-old SD rats were randomly divided into sham-operation group, HIBD group, low dose of Quercetin group (20 mg/kg), and high dose of Quercetin group (40 mg/kg), each of 14 rats. Except for sham-operation group, in the other groups HIBD model were made by right common carotid artery ligation and anoxiate. The Quercetin groups were injected with the corresponding doses of Quercetin immediately once a day continuously for 7 days after the model was made,. Sham-operation group and HIBD group were intraperitoneally injected with normal saline at the same time. Neural function was evaluated by Hanging wire test and Vertical pole test at 21 days old. The capacity of learning and memory was detected by Morris water maze at 28 days old, and then rats were killed and brains were taken. HE was used to observe the pathological changes of hippocampus. Western blot were used to detect the expression of PARP-1 and AIF in hippocampus. Results Compared with sham-operation group, the neural function and learning and memory ability decreased significantly in HIBD group. Those ability in both low dose and high dose of Quercetin groups were remarkably increased in comparison with HIBD group, and there were statistic differences (P?0.05). HE showed an neuro-structure was intact and neatly arranged in hippocampus in sham-operation group. The neurons in HIBD group were obviously decreased in number and loosely arranged while those in both low dose and high dose of Quercetin groups were more increased and neatly arranged when compared with HIBD group. The expressions of PARP-1, AIF, and Bax in rats’ hippocampus were higher in HIBD group than those in low dose or high dose of Quercetin groups which were higher than those in sham-operation group. The change of Bcl-2 was the opposite, and there were statistic differences (P?0.05). Furthermore, there was no difference between low dose of Quercetin group and high dose of Quercetin group in neural function, learning and memory ability, the expressions of PARP-1, AIF, Bcl-2, and Bax (P?>?0.05). Conclusion Quercetin could improve long-term learning memory in newborn rats with HIBD, and the mechanism may be down-regulation of PARP-1/AIF cell apoptosis signaling pathway, inhibition of neuronal apoptosis, and thus play a role in protection of brain.

Journal of Clinical Pediatrics 2017;35(3):218-222
Objective To explore the protective effects of Quercetin on hypoxic ischemic brain damage (HIBD). Methods Forty-eight 7-day-old SD rats were randomly divided into sham-operation group, HIBD group and Que treatment group, 16 rats each. HIBD group and Que treatment group were treated by ligation of right common carotid artery to make anoxia and build HIBD model; sham-operation group had the separation of the right common carotid artery only. Que treatment group were injected intraperitoneally with quercetin (40 mg/kg) once a day for 7 days immediately after modeling while sham-operation group and HIBD group received equivalent normal saline at the same time. The rats in each group were scored of neurological function at 1 h after the last administration, and the ability of spatial learning-memory was tested by Morris water maze at the age of 28 days. After performing the test above, all rats were decapitated and the brains were taken. Pathological changes of hippocampus were observed by HE staining; the expression of brain-derived neurotrophic factor (BDNF) and nerve growth associated protein (GAP-43) in hippocampus CA1 area were detected by immunohistochemistry. Results There were significant differences in neurological deficit score and learning-memory ability among the three groups (P<0.01), and neurological deficit score was the highest and the learning-memory ability was the lowest in HIBD group. Pathological examination showed that the structure of hippocampal neurons was intact in sham-operation group. It was loose and disorder, and even loss of neurons in HIBD group. Compared with the HIBD group, the loose in the structure of hippocampal was lighter, and the number of neurons was increased in the Que treatment group. There was statistical difference in the positive expression of BDNF and GAP-43 in the hippocampal CA1 area among the three groups (P<0.01), with those in HIBD group being lower than in Que treatment group and sham-operation group and those in treatment group being lower than in sham-operation group (P<0.01). Conclusions Quercetin can enhance the expression of BDNF and GAP-43 in hippocampal CA1 region, promote nerve regeneration, improve the long-term learning-memory ability of HIBD neonatal rats, and protect the brain.

Objective To explore the feasibility of inherent depressive Fawn-Hooded (FH/Wjd)rats as a comorbidity model of mental disorder and irritable bowel syndrome (IBS) by comparing visceral sensitivity of FH/Wjd rats and Sprague-Dawley (SD) rats. Methods Depression trait of FH/Wjd rats was validated through forced swimming test (FST) and sucrose preference test (SPT).Visceral sensitivity to colorectal distention (CRD) under various pressures was assessed by abdominal withdrawal reflex (AWR). The expression of 5-HT in rats' colon,c-fos expression in colon and brain areas of infralimbic cortex (IL),prelimbic cortex (PrL) and rostral anterior cingulated cortex (rACC)was tested with immunohistochemistry. Results FST indicated that the immobility time of FH/Wjd rats was significantly longer than that in SD rats (t=-8. 931,P<0. 01). SPT showed that the ratio of sucrose water in total liquid consumed was significantly lower in FH/Wjd rats than that of SD rats(t=4. 155,P=0. 01). At each CRD pressure gradient (20,40,60 and 80 mm Hg,1 mm Hg=0. 133kPa),AWR score was all significantly higher in FH/Wjd rats than that of SD rats (t=-2. 697,-3.464,-6.822 and -3. 976,P=0. 022,0.006,0.000 and 0.003). The expression level of 5-HT in FH/Wjd rats' control group was significantly higher than that of SD rats' control group (t=-11.371,P=0. 000). Compared with their own control group,5-HT expression increased both in FH/Wjd rats dilated groups and SD rats dilated groups,and the expression level in FH/Wjd rats was higher than that of SD rats (t= -3. 364,P= 0. 007). There was no significant difference of c-fos expression in colon and prefrontal brain areas between FH/Wjd rats' control group and SD rats'control group (colon:t=-0. 129,P= 0. 900;IL:t=-1. 316,P= 0. 218;PrL:t=1. 241,P = 0. 243;rACC:t=2. 151,P = 0. 057). Compared with their own control group,the expression of c-fos in colon and prefrontal brain areas significantly increased both in FH/Wjd rats dilated groups and SD rats dilated groups,and the expression level in FH/Wjd rats was higher than that of SD rats (colon: t=- 5.864,P= 0.000;IL:t=-2. 530,P = 0. 030;PrL:t=-7. 039,P= 0. 000;rACC:t=-6. 489,P=0. 000). Conclusions Inherent depressive FH/Wjd rats present visceral hypersensitivity. Meanwhile,the expression of 5-HT in colon is high,and with hyperreactivity to visceral noxious stimuli in colon and brain IL,PrL,and rACC areas. FH/Wjd rats might be a comorbidity animal model of mental disorder and IBS.
