Objective: To evaluate the quality of Radix bupleuri from different producing areas and make a comparison by using grey correlation analysis(GRA)and principal components analysis(PCA).Methods: Fifteen samples of Radix bupleuri were collected from different producing areas.The percentage of total ash, acid-insoluble ash, extract, saikosaponin a and saikosaponin d of Radix bupleuri from different habitats were determined.The grey correlation quality evaluation model was built for Radix bupleuri from different producing areas and the results were compared with those of PCA.Results: According to the grey correlation analysis on components in the different batches of Radix bupleuri , the samples from Shaanxi province were the most highly correlated with the optimal reference sequence (0.79), which suggested the best quality.Radix bupleuri Fructus from Hebei province was the most poorly correlated with the optimal reference sequence (0.23), which showed the worst quality.The results were basically identical with those of PCA, indicating good repeatability and stability.Conclusion: Grey incidence degree method and the established Radix bupleuri quality evaluation models can be used to evaluate the quality of Radix bupleuri .

BACKGROUND: Disturbance of mitochondrial fission and fusion (termed mitochondrial dynamics) is one of the leading causes of ischemia/reperfusion (I/R)-induced myocardial injury. Previous studies showed that mitochondrial aldehyde dehydrogenase 2 (ALDH2) conferred cardioprotective effect against myocardial I/R injury and suppressed I/R-induced excessive mitophagy in cardiomyocytes. However, whether ALDH2 participates in the regulation of mitochondrial dynamics during myocardial I/R injury remains unknown. METHODS: In the present study, we investigated the effect of ALDH2 on mitochondrial dynamics and the underlying mechanisms using the H9c2 cells exposed to hypoxia/reoxygenation (H/R) as an in vitro model of myocardial I/R injury. RESULTS: Cardiomyocyte apoptosis was significantly increased after oxygen-glucose deprivation and reoxygenation (OGD/R), and ALDH2 activation largely decreased the cardiomyocyte apoptosis. Additionally, we found that both ALDH2 activation and overexpression significantly inhibited the increased mitochondrial fission after OGD/R. Furthermore, we found that ALDH2 dominantly suppressed dynamin-related protein 1 (Drp1) phosphorylation (Ser616) and adenosine monophosphate-activated protein kinase (AMPK) phosphorylation (Thr172) but not interfered with the expression levels of mitochondrial shaping proteins. CONCLUSIONS: We demonstrate the protective effect of ALDH2 against cardiomyocyte H/R injury with a novel mechanism on mitochondrial fission/fusion.

Objective To evaluate the safety and efficacy of basic immunization with different sequential immunization programs of oral live attenuated poliomyelitis vaccine(OPV)and inactivated poliomyelitis vaccine(IPV). Methods Infants above two months of age residing in Pudong New Area,Shanghai,were selected for the study,and the basic immunization program of OPV full course(O-O-O group),sequential IPV and OPV(I-I-O group),and IPV full course(I-I-I group)were administered at 2,3 and 4 months of age,respectively. Relevant adverse reactions were proactively monitored by the parents of the participants via completing their own self-observation form after immunization. Before and after immunization,blood samples were collected from the upper arm vein,and the serum was separated. The neutralizing antibody levels of poliovirus in serum were measured by micro neutralization test,and the antibody positive rate and geometric mean titer(GMT)were calculated. Logistic multivariate regression analysis was used to research the effects of group,gender,household registration,birth mass and positive rate of typeⅠ/Ⅲ antibody before immunizationon the positive rate of type Ⅰ/Ⅲ antibody after basic immunization. Results There were one case of lethargy and one case of crying in O-O-O group, one case of lethargy in I-I-O group,and one case of crying in I-I-I group. The GMTs of type I neutralizing antibody in the pre-immunization O-O-O group,I-I-O group,and I-I-I group were 41. 39,8. 21,and 12. 56,and those of type Ⅲ neutralizing antibody were 7. 57,4. 02 and 8. 08,respectively. There was no significant difference in GMT between groups for typeⅠandⅢneutralizing antibodies before immunization(F = 2. 815 and 0. 608,P = 0. 061 and 0. 545,respectively). The positive rates of type Ⅰ antibody before immunization were 24. 04%,34. 07% and 41. 00%,respectively,with significant difference between groups(χ~2= 13. 459,P = 0. 001). The positive rates of type Ⅲ antibody were 13. 94%,9. 89% and 18. 00%,respectively,with no significant difference(χ~2= 5. 188,P = 0. 075). After immunization,the GMTs of type Ⅰ neutralizing antibody were 1 311. 84,1 812. 59 and 833. 24,and those of type Ⅲ neutralizing antibody were 911. 97,1 752. 68 and 419. 50,respectively,with significant differences between groups(F = 76. 848 and 202. 632,respectively,each P < 0. 001). After immunization,the positive conversion rates of type Ⅰantibody were 98. 56%,100% and 100%,and those of type Ⅲ antibody were 99. 04%,100% and 99. 44%,respectively,with no significant difference between the two groups(χ~2= 2. 973 and 1. 045,P = 0. 122 and 0. 789,respectively). In addition,group,gender,household registration,birth mass and positive rate of typeⅠ/Ⅲantibody before immunization had no effect on the positive conversion rate of typeⅠ/Ⅲantibody after basic immunization. Conclusion All three sequential immunization programs achieved good safety and high antibody positive conversion rates after basic immunization.
