ObjectiveTo observe the morphological changes of enteric nerve-interstitial cells of Cajal (ICC) network in rats with the bacterial peritonitis, and to investigate the main cause of gastrointestinal dysfunction and gastrointestinal failure with the bacterial peritonitis. Methods Sixty Wistar rats of both sexes were randomly divided into two groups. The model of the bacterial peritonitis was established.To record the frequency and amplitude of slow wave in myoelectricity of intestine in vivo to assess the function of the intestine motility. The proximal 10.0 cm segment of jejunum beginning 2 cm distal to the pylorus from each group was studied using c-Kit and vesicular acetylcholine transporter (VAChT)/ neuronal nitric oxide synthase (nNOS) immunohistochemical double-staining with whole-mount preparation technique and laser scanning confocal microscopy(CLSM). Results Compared the result of the bacterial peritonitis group with the normal group, it was found that the frequency and amplitude of slow wave in myoelectricity of intestine of the bacterial peritonitis group were slower and lower than the normal group, CLSM scanned ICC network showed that compared with the control group, the distributions and densities of ICC of intestine in the bacterial peritonitis group decreased significantly(P<0.01), the number of ICC synapse decreased, the cell junction between ICC and the ICC network was disrupted, and the fluorescence intension of cell decreased. CLSM scanned enteric nerve-ICC network indicated that compared with the control group, in the bacterial peritonitis group, the distributions and densities of cholinergic nerves (P<0.01)/ nitrergic nerves(P<0.01)and ICC(P<0.01)of intestine significantly decreased respectively, the cell junction between enteric nerve and enteric nerve -ICC network was disrupted, and the fluorescence intension of enteric nerve -ICC network decreased. The network of cholinergic/nitrergic nerve-ICC was disrupted. Conclusion The number of cholinergic nerves and nitrergic nerves were reduced, and the enteric nerve-ICC network was damaged in rats with bacterial peritonitis. Gastrointestinal motility dysfunction can be caused by the bacterial peritonitis.

OBJECTIVETo explore the effect of 3-n-butylphthalide pretreatment on the delayed neuronal death(DND) and the expreesion of heat shock protein70 (HSP70) in rat hippocampus after ischemia/ reperfusion.

METHODSAll rats were randomly divided into sham group (n = 36), total cerebral ischemia (TCI) group (n = 36), butylphthalide (NBP) group (n = 6), NBP + TCI group( n = 36), quercetin + NBP + TCI group (n = 6), dimethyl sulfoxide (DMSO) + NBP + TCI group (n = 6). The model of total cerebral ischemia/reperfusion was established by blocking vertebral arteries and carotid arteries. In sham group, TCI group and NBP group, the animals were further divided into instantly, 6 h, 12 h, 1 d, 3 d, 5 d groups according to the time interval after sham operation or TCI. Histological changes of the hippocampus were evaluated using thionin staining under light microscope by determining the delayed neuronal death (DND) and the expression of HSP70 was assayed using immunohistochemistry.

RESULTSNBP pretreatment could reduce delayed neuronal death in CA1 of hippocampus induced by TCI-reperfusion injury in rats, and up-regulated the expression of HSP70 in CA1 hippocampus of brain ischemic/reperfusion for 5 days. Quercetin blocked the acquirement of the brain ischemic tolerance induced by NBP preconditioning.

CONCLUSION3-n-butylphthalide (NBP) prevents the neurons from ischemia/reperfusion injury through upregulating the expression of HSP70.

Objective To explore the neuropsychological development in twin premature infants,and to analyze the risk factors for the retardation of development.Methods The premature infants hospitalized in the Neonatal Ward First Affiliated Hospital of Kunming Medical University from Jun.2010 to Jun.2012 were divided into study groups of twin premature infants and a control group of singleton premature infants.The neuropsychological development of 88 premature infants was evaluated at corrected gestational age of 1 year old by Bayley scales of infant development.According to normal lab findings of the Bayley scales of infant development,the premature infants were then divided into abnormal neuropsychological development group [mental development index(MDI) ≤79 scores] and normal neuropsychological development group (MDI ＞ 79 scores),and the data of 2 groups were statistically analyzed.Results The frequency distribution of MDI score in study group showed a skewed distribution,of which 59％ (27/46 cases) had abnormal neuropsychological development (MDI ≤ 79 scores); However,the frequency distribution of MDI score in control group showed an approximate normal distribution,of which only 12％ (5/42 cases) for abnormal neuropsychological development.Head circumference,body length,body weight,MDI,psycho-motor development index of twin premature infants of one-year old were lower than those of the singleton premature infants of the same age,and the differences were statistically significant (all P ＜0.05).The single factor analysis demonstrated that the risk factors for abnormal neuropsychological development (MDI ≤ 79 scores) of twin premature infants were gestational age,birth weight,mother' s gcstational age,the cultural degree of parents,mode of feeding,neonatal hyperbilirubinemia,neonatal hypoglycemia and neonatal sepsis.Multiple regression analysis showed that neonatal hyperbilirubinemia was the independent risk factor for abnormal neuropsychological development of twin premature infants.Conclusions At same gestational age,neuropsychological development of twin premature infants lagged behind singleton premature infants.Neonatal hyperbilirubinemia may be the risk factors for neuropsychological development of twin premature infants,so the earlier management of neonatal hyperbilirubinemia may be beneficial for the neuropsychological development of twin premature infants.
