＜正＞ There is no absolute safety in using herbals in medicine and food. For example, when the apricot kernel is processed and used as a snack or food ingredient, it is nutritional and safe. But if it is overdosed, or not processed properly, it will cause poisoning or even death. For the safe use of herbals and their products, we must emphasize reasonable safety, taking into account their acute and chronic toxicity, as well as special toxicity, mutagenicity and carcinogenic

The two basalt groups define two populations on most elemental and isotopic diagrams. The lower group basalts display strong subcontinental lithospheric mantle affinities and large variableεNd(t)) andεHf(t)) values that correlate negatively with Th/Ta and positively with *** upper group basalts,on the other hand,show ocean-island basalt(OIB) affinities and highly positiveεHf(t)) andεNd(t)) values. Numerical modeling indicates that the lower and upper group basalts were formed at melting temperatures of>13.0℃and>1450℃and mantle potential temperatures of 1400- 1488℃and 1550±3.℃,***, the upper group basalts were derived from an anomalously hot asthenosphere mantle,～160℃hotter than the contemporary ambient mid-ocean-ridge basalt(MORB) source *** results are at clear variance with the alternative tectonic model that the Bikou basalts were part of a continental magmatic *** work suggests that the Bikou basalts are likely the remnants of Neoproterozoic continental flood basalts that formed in response to a mantle plume starting ca.825 Ma during the breakup of the supercontinent Rodinia.

Based on the theories and methods of cartography on spatial pattern and temporal evolution in Geo-information Tupu (Carto-methodology in Geo-information, CMGI) and the quantitative measurements of pattern and process in landscape ecology, the methodology of landscape information Tupu in studying the swing process of the Yellow River (YR) over the Yellow River Delta (YRD) during 1855― 2000 has been demonstrated. The main content includes: (1) methodology of landscape information Tupu; (2) evolution process Tupu of YR rump channels; (3. evolution process Tupu of the 7 pieces of subdeltas in YRD during 1855―2000; (4) landscape information Tupu of the modern YRD and the current YRD; (5) landscape information Tupu of YR rump channels on the 7 pieces of subdeltas during 1855―2000; and (6) corridor-matrix landscape information Tupu by YR swings. The methodology of landscape information Tupu here is still primary but we hope that it could provide a new tool for exploring an integrated research on spatiotemporal approaches for landscape "pattern and process".
