Objective To investigate the effects of divitamins notonginseng and cinnarizine capsule(DNCC) on acute cerebral ischemia.Methods ICR mice were administered three doses of DNCC(420,210,and 105mg/kg;ig.) for ten days,then the gasping time after decapitation was recorded.After three doses of DNCC(292,146,and 73mg/kg;ig.) were given respectively for ten days in rats,the effects of DNCC on the infarct size,histological changes and neurological function scores caused by focal cerebral ischemia which was induced by middle cerebral artery occlusion were investigated.Results DNCC prolonged the gasping time of mice after decapitation and improved the neurological function scores,cerebral ischemia injury and decreased the infarct size in rats.Conclusion DNCC has a protective effect against acute cerebral ischemia.

BACKGROUND: Cell apoptosis is one of the important pathological changes in ischemic-reperfusion (IR) injury. As the key factor involved in cell apoptosis regulation, interleukin (IL)-iβ converting enzyme, when activated, leads to cell apoptosis via protein degradation.OBJECTIVE: To investigate the relationship between the expression of IL-1β converting enzyme and cell apoptosis in cerebral IR injury and explore the role of this enzyme in post-ischemia cell apoptosis.DESIGN: Randomized controlled experiment.MATERIALS: The experiment was performed at the Center of Neuroscience of the Third Military Medical University between March 1996 and December 2000. Totally 64 adult healthy Wistar rats were randomized into two groups, namely IR group (n=56) and sham operation group (n=8). In IR group, the rats were subjected to four vessel occlusion to mimic whole brain IR injury, and reperfusion was carried out after 30 minutes of ischemia for 3, 6, 12, 24, 48, 72 hours and 7 days, respectively (8 rats at each time point). Only separation but not occlusion of the bilateral common carotid artery was performed in sham operation group.METHODS: Four rats were randomly selected from IR group at each time point and 4 from the sham operation group for immunohistochemical study and in situ hybridization, with the other 4 rats for in situ end-labeling assay.MAIN OUTCOME MEASURES: Protein and mRNA expression of ILlβ converting enzyme and neural cell apoptosis in the brain.RESULTS: Totally 64 rats were used in this study and all data were statistically analyzed. In the sham operation group, IL-1β converting enzyme protein and mRNA were expressed in small amount in most of the normal brain tissues, and their expressions were also detected in the neurons and small glial cells in IR group localized mainly in the cerebral cortex, cerebellum Purkinje's cells, hippocampal and subcortical white matters. The expression of IL-lβ converting enzyme began to increase at IR 12 hours, reaching the peak level at 48-72 hours followed by declination since 7 days after the operation. Cell apoptosis occurred 12 hours after IR (49.4±6.8) /section and peaked at 72 hours (228.6±29.8)/section, showing significant correlation with the temporal expression of IL-1β converting enzyme protein and mRNA (r=0.89, 0.68, P ＜ 0.05).CONCLUSIONS: Expressions of IL-1β converting enzyme protein and mRNA increased after IR in close correlation with post-ischemia cell apoptosis, and their temporal expression pattern supports the presumption that IL-1β converting enzyme is an important factor in cell apoptosis.Apoptosis is mostly likely to occur in the cerebral cortex, hippocampus and basal ganglion in IR injury, where IL-1β converting enzyme is highly expressed, further demonstrating that post-ischemia expression of IL-1β converting enzyme might be involved in cell apoptosis regulation.

It provided a basic scientific platform for the development, research and use of minority medicine. The books and journals published since the late 1970s (the country after the reform and opening up) had been collected, classified. And reference books on current Chinese minority medicine had been compiled. The results showed that the first draft of the book had been completed and delivered to the press. The dictionary had cited 53 traditional medicine used by minority groups. The total number of minority medicine was 7 734. The total characters amount in the book was 1 700 000 words. It was concluded that the species of minority medicine were various. There was rich information on their harvest, medicinal parts, functions and indications with prominent features. The existing major problems were to clarify the standard of the species as well as their major functions and indications.

OBJECTIVETo study the morphological and anatomical characteristics of Coptis deltoidea based on the research of its breeding system.

METHODThe flowering process of C. deltoidea was observed dynamically and the out-crossing index was estimated, using Motic BA200 microscope to observe the morphologic characteristics of the mixed bud, stolon and pollen was observed microscopically, and compared with those of C. chinensis.

RESULTThe results showed that the breeding system of C. deltoidea was facultative hybridization, it could bloom normally and fruit while cannot form seeds. And there were no statistical differences in the number of stamens, pistils, ovules, pollens in a stamen, pollens in a flower, pollen-ovule ratio, and the pollen grain size between C. deltoidea and C. chinensis. However the pollen of C. deltoidea developed anomaly, most of the pollen grains in it were surface depression, the texture was unsharp or broken, the pollen could not germinate. The lateral bud on the lower side of the mixed bud formed in the bud stage. Pericyclic fibers in the stolon (the vegetative propagation branch) shaped like a cap, and all the shaped-caps nearly formed a ring.

CONCLUSIONThe abnormal development of the pollen could be the mainly cause to the no formation of seeds in C. deltoidea. The lateral bud forming in the bud stage then developing the stolon is the characteristics of the asexual propagation. Pericycle fibers in the stolon nearly forming a ring is a secondary character to accommodate the vegetative propagation of C. deltoidea.

ObjectiveHost mitochondrial DNA （mtDNA） and chloroplast DNA （cpDNA） contamination severely affects high-throughput sequencing of endophytic bacteria in plants. This study aims to explore and evaluate a novel strategy of inhibiting host gene amplification in high-throughput sequencing of endophytic bacteria in medicinal plants. MethodGreen Shield Sequencing （GSS） was introduced in the 16S rDNA polymerase chain reaction （PCR） of endophytic bacteria to shield the non-target amplification of genes in the host （Ligusticum chuanxiong）. The performance was compared between GSS-PCR and conventional PCR in the high-throughput sequencing of endophytic bacteria and rhizosphere soil bacteria. ResultCompared with conventional PCR， GSS-PCR significantly reduced the amplification of mtDNA and cpDNA in L. chuanxiong in high-throughput sequencing， decreasing the non-target genes by more than 60%. Moreover， this strategy significantly increased the diversity of endophytic bacteria and multiplied the species without compromising the extraction of the information about the dominant bacteria. The GSS amplification of 16S rDNA V4 region of L. chuanxiong showed lower host contamination rate and higher endophytic bacterial diversity than that of V3-V4 regions. ConclusionGSS can significantly reduce host gene contamination in the high-throughput sequencing of L. chuanxiong endophytic bacteria and improve the accuracy of endophytic bacterial diversity analysis at the same sequencing depth， thus improving the high-throughput analysis quality of endophytic bacteria in plants. Accordingly， this strategy improves the feasibility and reliability of high-throughput sequencing for the 16S rDNA V3-V4 and V4 regions of endophytic bacteria. GSS used in this study provides a method reference for studying the endophytic bacteria in other medicinal plants.
