Arnebia euchroma is the main source for medicinal herb Zicao. and its most important component shikonin compounds have high medicinal and industrial value. This research is aimed to build overexpression vectors and RNAi vectors for key secondary metabolism genes of A. euchroma, and bulid platform for constructions of related transgenic lines using GATEWAY technology. To build genetic material based genetic research platform is to provide a great convenience for digging and functional verification of the genes on secondary metabolic pathway, and also to fill the gaps in transgenic research of A. euchroma. This study is also important for the cultivation of shikonin high-yielding strains of A. euchroma.

Twenty-seven ERF transcription factor family genes were isolated from Arnebia euchroma, with an average size of 1,010 bp, each gene encoded a 212 amino acids on average. The gene structure and expression of physicochemical properties, subcellular localization, signal peptides, senior structural domains and conservative forecasting, and analysis of A. euchroma were studied comparing with ERF gene gi261363612 of Lithospermum erythrorhizon, and phylogenetic analysis of A. euchroma ERF family was carried out. The results showed the existence of three conserved domains in this family, the senior structure based on random coil and it clustered into CBF/DREB and ERF subfamilies.

OBJECTIVETo study the rehabilitation effects ergometry on COPD patients.

METHODSThirty COPD out-patients in our Hospital were randomly divided into 2 groups. Rehabilitation group, 15 patients, performed leg ergometry exercise of 80% peak Watt x 30min/d x 3d/w x 12w. Another 15 patients were control group without exercise. All patients received conventional therapy. Pulmonary function testing (PFT), cardiopulmonary exercise testing (CPET), arterial blood gas analysis (ABG), Borg and CAT sores were done at both baseline and 12 w.

RESULTSThere was no statistically difference in lung function testing, blood gas analysis and cardiopulmonary exercise test when pre- exercises between 2 sub-groups. The IC, peak VO2 and peak, W of rehabilitation group significantly increased (P < 0.05); and Borg and CAT.scores significantly decreased (P < 0.05) from baseline; and other PFT and ABG did not change (P > 0.05). While there was no difference in control group (P > 0.05).

CONCLUSIONLeg submaximal ergometry rehabilitation improves health condition and ameliorate dyspnea symptoms in COPD patients.

Maintaining genetic diversity is a major issue in conservation biology. In this study, we demonstrate the differences of genetic diversity levels between wild and captive individuals of Elliot's Pheasant Syrmaticus ellioti. Wild individuals showed a higher genetic diversity level than that of the captive individuals. Nucleotide diversity and haplotype diversity of wild individuals were 0.00628 and 0.993, while those of captive individuals were 0.00150 and 0.584 respectively. Only 3 haplotypes of mtDNA control region sequence were identified among 36 captive individuals, while 16 unique haplotypes were identified among the 17wild individuals in this study. One captive haplotype was shared by a wild individual from Anhui Province. It is concluded that a low number of founders was the likely reason for the lower level genetic diversity of the captive group. Careful genetic management is suggested for captive populations, particularly of such an endangered species, to maintain genetic variability levels.

To offer the reference and method for salt damage in the cultivation of Marsdenia tenacissima, the seeds of M. tenacissima collected from Maguan city ( Yunnan province) were taken as the test materials to study the effects of different priming materials on improving germination and growth under high-level salt stress condition. Four different treatments, which were GA3, KNO3-KH2PO4, PEG-6000, NaCl, combined with ANOVA were applied to test the performance of germination energy, germination percentage, germination index, MDA, SOD, and CAT. The results showed that the seed germination was obviously inhibited under salt stress and the soaked seeds with different priming materials could alleviate the damage of salt stress. Under these treatments, the activities of SOD, CAT the content of soluble protein significantly increased. While the content of MDA significantly decreased. The maximum index was obtained when treated with 1.20% KNO3-KH2PO4, the germination percentage increased from 52.67% to 87.33% and the activity of SOD increased from 138.01 to 219.44 respectively. Comparing with the treatment of 1.20% KNO3-KH2PO4, the germination percentage of treating with 300 mg x L(-1) GA3 increased from 52.67% to 80.67%, while the activity of SOD increased from 138.01 to 444.61.

In this paper, Fourier transform infrared spectroscopy fingerprint analysis of Marsdenia tenacissima samples was used to develop a reliable method of tracing the geographical origins. Forty-eight samples from four provinces of China were analyzed by FTIR. We analyzed and characterized the fingerprints in both the full spectrum peaks and characteristic peaks, then the principal component analysis and the cluster analysis were carried out. The results of fingerprint analysis, correlation analysis, principal component analysis and cluster analysis can identify the geographic origins correctly, which verified and supplemented each other; the identification results and the actual location showed a high degree of consistency, namely the lower the space distance, the greater the similarity of different samples. These results revealed the obvious superiority and practical value in comparison to the more tedious and time-consuming wet chemistry method normally used. Using appropriate metrology methods can trace the geographical source correctly. The M. tenacissima materials from the region of Maguan should be considered as genuine medicinal materials taking into account the good quality.

Based on the ecological and economic problems in Good Agriculture Practice (GAP) of Chinese material medica, we introduced the origin, concept, features and operative technology of eco-agriculture worldwide, emphasizing its modes on different biological levels of landscape, ecosystem, community, population, individual and gene in China. And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.
