Background. Daodi medicinal material is widely used in Chinese herb medication. However, there is a lack of systematic methodology for identifying characteristics associated with good quality and reliable efficacy of Daodi med-material. Purpose. The purpose of this study is to provide some evidence to further substantiate the use of Daodi medicinal materials. Methods. Seven relevant databases were searched before July 2014. Two evaluators were responsible for screening and categorizing the results. The data was analyzed with Microsoft Excel 2007 and SPSS 21.0 statistical software. Results. Overall, 107 articles were systematically analyzed. Of these studies, 55.1% (59/107) focused on the methodology to assess Daodi med-material, and 38.3% (41/107) were interested in med-material ingredients, soil physical and chemical properties, and the geological background system (GBS). Only 6.5% (7/107) of studies were mainly conducted as clinical trials and animal experiments. Conclusion. Comparisons between Daodi and non-Daodi materials have been studied mainly in terms of the ingredients or composition of medical materials, soil physics and chemistry, and the GBS, and some identifying methodologies have been created to identify Daodi attributes. Until now, there is still no consensus of comparison criteria between Daodi and non-Daodi medicinal material. Only a few studies were conducted through animal experiments and clinical trials to determine Daodi superiority.

Purpose: Preparation of gel-formed Dachuanxiong prescription. Method: In this experiment, liquid chromatograph is used to measure the content of gastrodin in gastrodia elata and orthogonal design method is adopted to optimize the technological conditions for extracting gastrodin. Comprehensive evaluation is conducted based on examination factors including dry powder, glycerol, hydroxypropyl methylcellulose and borneol as well as indexes including viscosity, appearance and spreadability, through which prescription can be screened and optimized, and gel-formed Dachuanxiong prescription can thus be prepared. Result: Content of gastrodin in gastrodia elata as raw material is 0.53%, and excipient should be gel made from 1 g of ethanol, 1.5 g of hydroxypropyl methylcellulose, 10 g of glycerol, 0.01 g of borneol and 100 g of water. Conclusion: This technology for preparation of gel is stable and simple, which can increase the content of ferulic acid obviously. Preparation of pure traditional Chinese medicine is delivered through nasal mucosa to relieve headache and mainly used to treat headache.[1]Chuanxiong Prescription was established by Liu Wansu, a well-known doctor living in the Jin and Yuan Dynasty. In this prescription, ligusticum wallichii can invigorate the circulation of blood and promote the circulation of qi, and gastrodia elata can relieve dizziness and pain. Combination of them can realize a good effect for the treatment of migraine caused by blood stasis and fire. This prescription is simple and effective. Based on physical and chemical properties of various medical materials, active ingredients in them can be extracted with the method of alcohol extraction. [2-4]According to result of document retrieval and patent search, volume fraction, number of times of extraction and time of extraction should be used as conditions of examination. [1]However, it can be verified through in-depth research on physical and chemical properties and pharmacological actions of medical materials in the prescription as well as repetitive tests that number of times of extraction have an obvious influence on extraction rate. Based on the above content, factors of examination in the experiment are determined and examination through orthogonal experiment is thus carried out, through which technological conditions that can realize a high rate of extraction of gastrodin (index component) is screened out. This experiment selects the optimal technology for extracting gel which can relieve headache and be delivered through nasal mucosa, in which orthogonal test method is applied, and content of gastrodin is viewed as an index. Ethanol should be used in the optimal extraction technology. The optimal technology is stable and practicable, which can obviously increase the content of ferulic acid.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

Synthesis Of Materials

Biomimetics involves investigation of structure, function, and methods of synthesis of biological composite materials. The goal is to apply this information to the design and synthesis of materials for engineering applications.Properties of engineering materials are structure sensitive through the whole spectrum of dimensions from nanometer to macro scale. The goal in designing and processing of technological materials, therefore, is to control microstructural evolution at each of these dimensions so as to achieve predictable physical and chemical properties. Control at each successive level of dimension, however, is a major challenge as is the retention of integrity between successive levels. Engineering materials are rarely fabricated to achieve more than a few of the desired properties and the synthesis techniques usually involve high temperature or low pressure conditions that are energy inefficient and environmentally damaging.In contrast to human-made materials, organisms synthesize composites whose intricate structures are more controlled at each scale and hierarchical order.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.

Rostov Region belongs to the highly protected natural territories characterized by the continuous plowing. There territories are the only reserves with the soils preserved in their natural state. However, these areas often lack detailed information about the soils quality and composition. Surveying soils on these territories is crucial for determination of their basic physical and chemical properties. The resulted compilation of soil maps could lay a foundation for creating the Red Book of Soils and the formation of a section in the soil-geographical database of the Russian Federation. Subsequently, such information can be used as a background data for the main types of soils in the region. It will be also valuable during monitoring and justification of conservation measures.
