Objective To explore the effects of maternal hypercholanemia on the myocardium changes in rat fetus. Methods Thirty clean SD female rats were equally randomized to three groups after mating successfully.From the 13th to 20th day of gestation,group A and B were injected injected with sodium chloride(NS) as control.Total bile acid(TBA) and cardiac troponin I(cTnI) were measured in the maternal and fetal serum on the 21st day when all rats were killed.Fetal cardiac muscle cells were also collected for examination with light microscope and electronic microscope.Results (1)TBA in maternal and fetal serum were(22.32±8.12)μmol/L and(28.84±8.06) μmol/L,respectively in group A,(9.77±3.56)/μmol/L and(9.34±3.54) μmol/L in group B,and (3.60±1.78) μmol/L and(3.95±1.19) μmol/L in group C.Significant differences were found among groups(P<0.01).(2)Fetal death rates were significantly different among the three groups (P<0.05),with 30.11%,16.85%,and 7.05%,respectively.(3)Fetal cTnl were also found significant difference among groups(P<0.01),with(19.98±7.75)ng/ml,(11.41±3.64)ng/ml and(4.38±1.19)ng/ml,respectively.(4)The integrated scores of fetal necrosis area were significantly different in three groups(P<0.05),with 1.92±0.43,1.36±0.37 and 0.44±0.12,respectively.(5)Under electronic microscope,the number density of mitochondria in group A was lower than that in group C(P<0.05)while the average volume of mitochondria was larger in group A (P<0.05).The average volume of mitoehondria in group B was larger than that in group C(P<0.05) while no difference was found with regard to the number density between the two groups.The number density and average volume of myofibril in group A were lower than those in group C(P<0.05).The number density of myofibril in group B was higher than that in group C(P<0.05) while no difference was found with the average volume.(6)Positive correlations were found in maternal TBA,fetal TBA,fetal cTnI and the integrate of fetal necrosis area when comparing every two of the above factors. Conclusions Fetal myocardium is impaired obviously in hypercholanemia rats.The serum level of TBA and cTnI in fetal rats are positively correlated with each other.

Objective To observe the protective effect of erythropoietin (EPO) on anoxia of motoneurons after spinal cord injury in rats.Methods The motoneuron was dissociated from neonate Wistar rats and cultivated in vitro with deprivation of oxygen in the medium. The changes of morphology were observed by phase-contrast microscopy, and the expression of EPO receptor (EPOR) was detected with Western blotting. The survival rate of motoneuron was measured with methyl thiazolyl tetrazolium (MTT) assay, and the level of lactate dehydrogenase (LDH) was observed. Results Compared with the control group, the expression of EPOR and the level of LDH increased (P<0.01),and the survival rate of motoneuron decreased (P<0.01) in the anoxia group. Compared with the anoxia group, the expression of EPOR and the level of LDH decreased (P<0.05), and the survival rate of motoneuron increased (P<0.01) in the EPO group, which was related with the level of EPO. Conclusion EPO could relieve the damage of motoneuron caused by anoxia, especially by upregulating EPOR.

Objective: To establish the methods for extraction and isolation of punicalagin from pomegranate peel, and further study the purification and quantification of punicalagin. Methods: Using an ultrasonic-assisted extraction method, punicalagin in pomegranate peel was extracted at room temperature by 50% ethanol with 20-fold volume of raw material. The content of punicalagin in the crude extract was determined by HPLC. To optimize the purification process of punicalagin, static adsorption and desorption experi-ments were employed to study five kinds of macroporous adsorbent resins (D101, A8-8, NKA-9, HPD-100 and HPD-500) for the one with the highest purification efficacy of punicalagin. In addition, the technical parameters of the macroporous adsorbent resin were opti-mized to obtain punicalagin with higher purity. Punicalagin was further separated and purified by using a reverse phase MCI GEL CHP20P column. Results:HPD500 resin showed the best ability to absorb and separate punicalagin in among five kinds of macro-porous adsorbent resins. The best technical parameters were as follows:the mass concentration of sample solution was 15 mg·ml-1 , the loading amount was 2BV, the pH was 2 and the eluting solvent was 8BV of 30% ethanol. With the best process as described a-bove, the content of punicalagin extracted from pomegranate peel increased from 10. 3% to 30. 7%. The obtained punicalagin could be further purified to 61. 3% from 30% in ethanol eluate by the reverse phase MCI GEL CHP20P column. Conclusion:HPD500 resin is the most effective in the purification of punicalagin from pomegranate peel, and the content of punicalagin can be dramatically increased after the purification by a reverse phase MCI GEL CHP20P column. The optimized process shows good reproducibility and stability.
