Abstract
With the emergence of drug resistance in Western medicine, the repeated administration of clinical first-line drugs becomes more severe. There are many factors leading to multidrug resistance(MDR), so it is very difficult to solve the problem. Since traditional Chinese medicine(TCM) has been used in the field of MDR in recent years, the research on the transporter-associated drug resistance and intervention of TCM has gradually become a hot spot. Therefore, in order to further explore the relationships among drug resistance, transporters, and TCM intervention, we review the relevant research progress in recent years and comb the achievements and limitations of this research at present. In the end, we put forward the research direction of changing body's ADME through the host's transporters and gastrointestinal flora, which provides new ideas for future research.

Abstract
The purpose of this study was to explore the expression pattern of miRNA in the process of embryo dormancy and provide a reference for the mechanism of regulating seed dormancy and germination by miRNA. We used high-throughput sequencing technology, bioinformatics analysis and real-time fluorescent quantitative PCR(qPCR) technology to sequence, screen and identify miRNAs of dormant and dormant embryos. The results showed that there were 23 811 977, 24 276 695, 20 611 876 and 20 601 811 unique sequences in the four sample libraries during the period of dormancy and dormancy release. MiRNAs are mainly distributed between 21 and 24 nt, among which the length of 24 nt occurred most frequently. A total of 31 known miRNAs were identified, belonging to 13 different families. 93 new miRNAs were predicted by bioinformatics software. Ten miRNAs(mir156 a-5 p, mir160 a-5 p, mir160 h-1, mir169 a-5 p, mir157 d, mir159 a-1, mir395-3, mir156 f-5 p, mir156-2 and mir171 a-3 p) were screened out. In this study, 10 miRNAs related to seed dormancy release were identified. The target genes mainly involved carbohydrate metabolism, plant hormone signal transduction, cell division and growth. The results of qRT-PCR showed that the sequencing results were consistent with the actual results.

Abstract
In this study, the roots, stems and leaves of diploid and autotetraploid Dendrobium huoshanense were used as materials to compare their contents of polysaccharides and alkaloids, and the transcriptome sequencing analysis was carried out. The results showed that the contents of polysaccharides and alkaloids in the roots, stems and leaves of tetraploid were 7.6%, 34.5%, 17.2%, 0.01%, 0.024% and 0.035% higher than those of diploid D. huoshanense, respectively. The contents of active components in different tissues were significantly different. There were 3 687 differentially expressed genes in diploid and tetraploid D. huoshanense, of which 2 346 genes were up-regulated and 1 341 down regulated. Go functional analysis showed that these genes were mainly involved in growth and development, stress resistance and other related functions. KEGG pathway analysis showed that most of the differential genes were concentrated in the processes of carbon metabolism, signal transduction, carbohydrate metabolism, amino acid metabolism and energy metabolism. The differential expression of key genes involved in the metabolism of polysaccharides, terpenes and polyketones, amino acid metabolism, hormone synthesis and signal transduction in diploid and tetraploid plants may be the main reason for the high energy content, the increase of active components and the growth potential of tetraploid plants.

Abstract
Aquilaria sinensis is a typical inducible medicinal plant, that can produce agarwood only after it is wounded by external stimuli. Alternative oxidase(AOX) is one of the terminal oxidases of the plant mitochondrial electron transport, which plays an important role in plants' response to environmental stress. In order to reveal the physiological function of AOX gene in the process of agarwood formation from A.sinensis induced by wounding, AOX gene was cloned based on the transcriptome database and then identified by the bioinformatics analysis, and their expression pattern in different tissues and under wounding stress were detected by qRT-PCR. The results as follows. Three AOX genes were cloned from A.sinensis for the first time. They were named AsAOX1a, AsAOX1d and AsAOX2, respectively. The tissue expression shown that AsAOX1a is mainly expressed in the stem and the seed, and the AsAOX1d and AsAOX2 genes are mainly expressed in the pulp and the stem. AsAOX1a and AsAOX1d genes are highly responsive to wounding stress, and their response time was different. In addition, the expression of AsAOX1a and AsAOX2 induced by wounding are reduced by H_2O_2 treatment, but promoted by AsA treatment. The cloning, bioinformatics analysis and expression characteristics of AOX genes from A.sinensis provided basic information for further study the function of AOX genes in the development of A.sinensis, especially in the process of agarwood formation of A. sinensis induced by wounding.

Abstract
BACKGROUND Drugs derived from botany have been playing essential role in both clinical treatment and pharmaceutical industry, unfortunately our worry is still that its quality and therapeutic efficacy are inconsistent. Recently many scientists launched a new project on quality (Q)-marker of medicinal herbs, this study was thus designed to generate a novel concept of quality (Q)-markers: molecular connectivity index (MCI), and to test and verify the new concept of molecular connectivity index (MCI). METHODS The first-order term (1χ) was selected to calculate and study quality (Q)-marker for TCM. Houttuynia cordata Thunb. (HCT) was adopted as a model to verify the hypothesis. Volatile oils of HCT were determined using gas chromatography-mass (GC-MS). SIMCA 13.0 and SPSS 21.0 were used to deal with the data. RESULTS The minimum of the MCI values was 1.273, belonging to the peak 15, but the maximum (12.822) belonged to the peak 34, and the average value of fifty volatile oils was 5.798. The results demonstrated that MCI was the principle component, and monoterpenoid and sesquiterpenoid were also the principle components in oils. Fig. 2a shows peak 5, 24, 34 were the significant ingredients, while Fig. 2b shows peak 2, 5, 24 were the significant components. CONCLUSION The data demonstrated that MCI was associated with the structure of molecules and the therapeutic efficacy, MCI could directly exhibit the relationship between ingredients and effectiveness of Traditional Chinese Medicine (TCM). So MCI could be a potential and promising parameter for quality (Q)-marker. Therefore, MCI may be developed as a novel potential concept to control the quality of TCM.

Abstract
To explore the distribution and quantity of toxic epitopes in α-gliadins from Aegilops tauschii, a total of 133 complete α-gliadin coding sequences were obtained, including 69 pseudogenes with at least one premature stop codon and 64 genes with complete open reading frames (ORFs). Plenty of deletions and single amino acid substitutions were found in the 4 celiac disease (CD) toxic epitope domains through multiple alignments, in which the sequence of DQ2.5-glia-α2 demonstrated the most significant changes. Interestingly, 7 of the 59 α-gliadins were free of any kind of intact CD toxic epitopes, providing potential gene resources for low CD toxicity breeding of common wheat. Analysis of the neighbor-joining tree demonstrates that 2 of the totally 7 α-gliadins cluster within the homologues of Triticum (A genome), and the other 5 group with those of Aegilops Sitopsis (B genome). This result implies that the 7 α-gliadin genes may be originated from the ancestor species of Ae. tauschii, evolved by the homoploid hybrid of Triticum and Aegilops Sitopsis. The remaining 52 α-gliadins form a separate clade from other homologues of A and B genomes, suggesting a recent rapid gene expansion by gene duplication associated with the species adaptation.

Abstract
To clarify the effect of high molecular weight glutenin subunit (HMW-GS) from wild emmer wheat on flour quality, which has the same mobility as that from common wheat, the composition and molecular characterization of HMW-GS from wild emmer wheat accession TD-256, as well as its flour quality, were intensively analyzed. It is found that the mobilities of Glu-A1 and Glu-B1 subunits from TD-256 are consistent with those of bread wheat cv. 'XiaoYan 6'. Nevertheless, dough rheological properties of TD-256 reveal its poor flour quality. In the aspect of molecular structure from HMW-GS, only two conserved cysteine residues can be observed in the deduced protein sequence of 1Bx14* from TD-256, while most Glu-1Bx contain four conserved cysteine residues. In addition, as can be predicted from secondary structure, the quantity both of α-helixes and their amino acid residues of the subunits from TD-256 is fewer than those of common wheat. Though low molecular weight glutenin subunit (LMW-GS) and gliadin can also greatly influence flour quality, the protein structure of the HMW-GS revealed in this work can partly explain the poor flour quality of wild emmer accession TD-256.

Abstract
A novel microbial electrochemical snorkel (MES) bioreactor was constructed by inserting an iron rod into the sediment of a simulated natural water body for the first time. Its nitrate removal performance and mechanism were investigated. The DNA high-throughput sequencing analysis indicates that denitrifying bacteria were grown on the iron rod in the overlying solution. The XRD analysis on the oxides formed on the surface of the iron rod indicates that they are goethite and green rust. In the MES system, the green rust on the iron rod can concentrate nitrate and denitrifying bacteria, forming an anaerobic biocathode. The denitrifying bacteria can reduce the nitrate into nitrogen with the electrons moved from the sediment. The nitrate removal efficiency reached 98% in 16days. This novel MES system showed excellent in-situ nitrate removal performance by moving and concentrating the electrons in sediment and the nitrate in overlying solution in an anaerobic microenvironment.

Abstract
In this study, we evaluated the rat cortical bone changes after a two-cycle, 60-day each (ON/OFF/ON/OFF) treatment with either prostaglandin E2 (OVX/c-PGE2) alone or in combination with risedronate (OVX/c-PGE2+Ris), in comparison with daily treatment with PGE2 for 240 days (OVX/PGE2-240d) in ovariectomized (OVX) rats. At the end of the study, we found that: (1) the overall effectiveness of the treatment on bone mass in the tibial shaft indicates the following ranking: OVX/PGE2-240d = OVX/c-PGE2+Ris > OVX/c-PGE2 > OVX/c-Ris > or = OVX = aging; (2) the same bone mass and architecture were produced in the OVX/PGE2-240d and the OVX/c-PGE2+Ris groups, but the histomorphometric profiles differed in that the former exhibited a higher bone turnover and index of resorption; (3) OVX/c-PGE2+Ris treatment prevented endocortical bone loss and minimized trabecular bone loss during the OFF periods; and (4) the OVX/c-PGE2 alone treatment resulted in the accumulation of less total bone than OVX/PGE2-240d and OVX/c-PGE2+Ris because it could not maintain most of the new subendocortical and marrow trabecular bone generated earlier. In summary, both continuous daily PGE2 and two cycles ON/OFF combined PGE2 and Ris treatments result in more bone mass than two cycles ON/OFF PGE2 alone and Ris alone in estrogen-deficient rats. This study showed that the anabolic effects of PGE2 can be induced and maintained either by continuous administration or by cyclical PGE2+Ris.

Liang HH, Ma YF, Jee WS, Pan Z, Setterberg RB, McOsker JE, Li XJ. Risedronate plus prostaglandin E2 is superior to prostaglandin E2 alone in maintaining the added bone after withdrawal in a non-growing bone site in ovariectomized rats. Bone 1995; 17:335S-339S.

Abstract
Effects of risedronate and prostaglandin E2 (PGE2) alone or in combination on the distal tibia, a non-growing bone site with closed epiphysis at 3 months of age, were studied in ovariectomized (ovx) rats. Six-month-old Sprague-Dawley female rats were either ovx or sham-ovx. Rats were treated immediately after operation either with risedronate (5 micrograms/kg/2x/wk), PGE2 (6 mg/kg/d), or risedronate+PGE2 for 60 days (on-groups) and followed by 60 days without treatment (off-groups). Trabecular area, width and numbers were determined in metaphyseal cancellous bone of the distal tibia. No significant bone loss or structural changes were observed in the distal tibial metaphysis after 120 days of ovx. Risedronate alone did not produce any effect on bone mass during the treatment and the withdrawal periods. PGE2 alone increased the trabecular bone mass associated with thickened trabeculae and increased trabecular numbers. However, some of the newly formed bone was lost at the end of 60 days withdrawal. Combination of risedronate and PGE2 treatment added the same amount of bone mass as PGE2 alone, and the added new bone was maintained during the 60 days withdrawal. These results indicate that treatment with risedronate and PGE2 can preserve the anabolic effect of PGE2 on bone mass for at least 60 days after treatment.

Abstract
Midbrain neuronal activity that correlated with the initiation of locomotion produced by hypothalamic stimulation was studied. Locomotion was elicited by electrical stimulation in the perifornical hypothalamus of 59 rats anesthetized with Nembutal. The first hindlimb extension indexed stepping onset. Single and multiple neurons were recorded ipsilateral to the stimulation site at 2230 sites in the anterior and posterior midbrain. To classify responses, activity patterns averaged around stimulation onset and around the extension onset were examined. Responses with specific correlations to extension onset were Type I; responses not specifically related to the extension onset were Type II. In the anterior midbrain, 6% of sites were Type I and 8% were Type II. The larger Type I responses were frequent in the anterior tegmentum near the central gray. The relative frequency of Type I patterns in the posterior ventrolateral tegmentum was similar. Other regions showed relatively more Type II responses; they included the ventral tegmental area, and the regions near the superior cerebellar peduncle and the posterior central gray. Regional population profiles showed that during the initiation of locomotion, neurons in the posterior peribrachial region responded early and neurons in the anterior dorsal and the posterior ventrolateral tegmentum responded later. The initiation-related activity of Type I neurons in the anterior and posterior midbrain tegmentum suggest that they warrant further study for a role in locomotor initiation.
