ObjectiveTo compare the real-time analgesic effects between two different groups of acupoints in treating primary dysmenorrhea, for providing objective evidences for optimizing the treatment protocol for primary dysmenorrhea.MethodSixty eligible patients with primary dysmenorrhea were randomized into 3 groups: group A received acupuncture at Sanyinjiao (SP6), group B received acupuncture at Sanyinjiao and Guanyuan (CV4), and group C as a blank control group, 20 cases in each group. Visual Analogue Scale (VAS) was observed prior to the acupuncture treatment, after the insertion of the needles, and after removal of the needles in the three groups.ResultThe VAS scores changed significantly in group A and B after intervention (P<0.05); there was no significant difference in comparing the VAS score between group A and B after intervention (P>0.05).Conclusion Acupuncture at Sanyinjiao alone and acupuncture at Sanyinjiao and Guanyuan both can produce analgesic effect at the attackof primary dysmenorrhea. However, for optimizing the treatment protocol, selecting Sanyinjiao alone will be enough.

To compare the chemical change of Paeoniae Radix Alba (PRA) after vinegar-baking processing, as well as the effect of vinegar types exerted on the processing, 1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to investigate the different metabolites between the raw and two vinegar-baked PRA. More than thirty metabolites were identified in the 1H NMR spectrum of PRA, and the multivariate statistical analysis showed that raw and two vinegar-baked PRA could be separated obviously. After vinegar-baking, the contents of isoleucine, lactate, alanine, arginine, albiflorin, and 5-hydroxymethyl furfural (5-HMF) elevated, while those of sucrose, paeoniflorin and its analogues (calculated by benzoate) decreased. The chemical compositions of two vinegar-baked PRA were also different. Shanxi vinegar- baked PRA showed higher levels of leucine, isoleucine, valine, and albiflorin, while rice vinegar-baked PRA contained more sucrose and paeoniflorin's analogues (calculated by benzoate). And the chemical changes in Shanxi vinegar-baked PRA were greater than those of rice vinegar-baked PRA. The results revealed the chemical differences between raw and vinegar-baked PRA, as well as the influence of vinegar type on processing, in a holistic manner, the results obtained suggested that the correlations between the chemical change and the drug action after processing, as well as the vinegar type used in processing, should be further studied.

In this study, the embryological characters of Pterocypsela formosana (Asteraceae) were investigated with the traditional paraffin section methods. The anther has 4 sporangiates, the anther wall development follows the dicotyledonous type and comprises of an epidermis, endothelium, a middle layer and a single-layered tapetum, the tapetum belongs to glandular type. Meiosis of the microspore mother cells is of the simultaneous type, for the formation of mostly tetrahedral tetrad, the mature pollen grains are 2 celled. The ovary is bicarpellate, unilocular, one ovule and basal placenta, the ovule is unitegmic, tenuinucellate, inverted campylotropous and with developed endothelium, archesporial cell of megaspore differentiates immediately below the nucellar epidermis and functions as megasporocyte after development and belongs to tenuinucellate ovule type. The megasporocyte undergoes meitotic to form a liner tetrad, only one chalazal megaspore becomes the functional megaspore which forms female gametophyte including 7-celled and 8-nucleated after three successive mitosis, the female gametophyte is of the Polygonum type. Two polar nuclei melt into a secondary nuclei before fertilization, the chalazal antipodal cells are ephemeral and degenerate shortly after forming. Fertilization is porogamous and belongs to premitotic type of syngamy. The division of the primary endosperm nucleus is earlier than the zygote, the endosperm is of the nuclear type with the presence of haustoria, and the embryogeny belongs to asterad type chicory variant. The developed suspensor on early stage has important significance to the embryo development.
