Abstract
miR-30b, which is encoded by the gene located on chromosome 8q24.22, plays an important role in a variety of diseases. In most types of tumors, miR-30b significantly inhibits the proliferation, migration, and invasion of cancer cells through the regulation of target genes. Moreover, miR-30b can inhibit the PI3K/AKT signaling pathway through the regulation of EGFR, AKT, Derlin-1, GNA13, SIX1, and other target genes, thus inhibiting the EMT process of tumor cells and promoting apoptosis. In addition, miR-30 plays a significant role in alleviating drug resistance in tumor cells. Although the use of miR-30b as a clinical diagnostic indicator or anticancer drug is still facing great difficulties in the short term, with the deepening of research, the potential application of miR-30b is emerging.

Abstract
In order to guide the standardized planting and scientific harvesting of Artemisia argyi var. argyi 'Qiai', effects of diffe-rent planting density, leaf position and leaf age on the growth and quality of A. argyi var. argyi 'Qiai' were studied in this paper. The results showed that appropriate sparse planting could increase stem diameter, compact leaf spacing, increase the leaf size, reduce the rate of withered leaves and increase the number of effective leaves. Dense planting can significantly increase the yield of A. argyi var. argyi 'Qiai' per Mu(1 Mu≈667 m~2) and the output rate of moxa, but reduce the yield per plant and the number of effective leaves. With the decrease of leaf position and the increase of leaf age, the leaf size and the weight of one hundred leaves increased at first and then decreased, the density of non-glandular hair field of the lower epidermis and the output rate of moxa decreased. With the increase of planting density, the contents of eucalyptus oleoresin, camphor, α-platyclone, and cyanidin decreased gradually, the contents of chlorogenic acid, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C in the leaves of A. argyi var. argyi 'Qiai' increased gradually, while the contents of borneol, bornyl acetate and isozelanin increased at first and then decreased significantly. With the decrease of leaf position and the increase of leaf age, the contents of volatile oil, phenolic acid and flavonoid in A. argyi var. argyi 'Qiai' decreased gradually. PCA analysis can divide the leaf quality characteristics of A. argyi var. argyi 'Qiai' into two parts: the middle and upper 10-30 days leaf age, the middle and lower 40-50 days above leaf age. Based on the above factors, the planting density of 28 000 plants/Mu(row spacing of 10 cm×20 cm) can be selected for cultivation of A. argyi var. argyi 'Qiai' rhizome, and the effective plants in the field are about 142 800 plants/Mu. In terms of harvesting, it is suggested that the A. argyi var. argyi 'Qiai' should be harvested on "March 3 rd" and "May 5 th" of the lunar calendar. If it is the traditionally harvested at one time in May, the A. argyi var. argyi 'Qiai' should be divided into two parts: the middle and upper leaves, the middle and lower leaves, so as to achieve high quality and high price of A. argyi var. argyi 'Qiai' leaves and improve the economic benefits of A. argyi var. argyi 'Qiai' planting.

Abstract
To solve the problems of the unclear planting period and the traditional flat planting of Artemisia argyi var.argyi 'Qiai', such as the serious dead leaves in the middle and lower parts of the plant and the low yield and low quality in the field, the effects of different planting period and ridge pattern on yield and quality of A. argyi var.argyi 'Qiai' were studied. The results showed that the growth and development of A. argyi var.argyi 'Qiai' was better when planted in autumn and winter, and the ridge directions had little effect on the growth and yield of A. argyi var.argyi 'Qiai', while the ridge width had a significant effect. Compared the traditional wide ridge planting mode(the width of the ridge is 160 cm) with the ridge width of 80 cm, 60 cm and 40 cm, the results showed that the density per unit area, the number of effective plants, and the rate of dead leaves were decreased, while the number of productive leaves per plant, the number of lateral branches, and the total yield per plant were increased, the total yield was decreased. The output rates of moxa in the leaves of A. argyi var.argyi 'Qiai' decreased with the planting time postponed and the width of planting ridge increased. The contents of volatile oil, 1,8-oxido-p-menthane, camphor and borneol in A. argyi var.argyi 'Qiai' reach to the highest when planted in autumn and winter and the ridge width was 80 cm. In addition, the contents of total flavonoids, kaempferol, jeceosidin and eupatilin flavonoids in the leaves of A. argyi var.argyi 'Qiai' gradually decreased as the planting period postponed and the ridge width increased. The results show that the A. argyi var.argyi 'Qiai' should be planted in autumn and winter, and the double row ridge planting mode with width of 60-80 cm is more suitable for the cultivation and production of A. argyi var.argyi 'Qiai' in Qichun County of Hubei Province. This study will provide a theoretical basis and guidance for higher yield and quality in cultivation of A. argyi var.argyi 'Qiai' in Qichun county.

Abstract
The endophytic bacterium, MD-b1, was isolated from the medicinal plant Ophiopogon japonicas and identified as the Bacillus amyloliquefaciens sp. with 99% similarity based on the partial sequence analysis of 16S rDNA. Exopolysaccharides were extracted from the endophyte for the evaluation of its antitumor activity against gastric carcinoma cell lines (MC-4 and SGC-7901). 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays and microscopy were performed to estimate the cell viability and morphological changes of the MC-4 and SGC-7901 cells following treatment with the exopolysaccharides at 14, 22 and 30 μg/μl. The results revealed that the exopolysaccharides displayed concentration-dependent inhibitory effects against the MC-4 and SGC-7901 cells, with an IC50 of 19.7 and 26.8 μg/μl, respectively. The exopolysaccharides also induced morphological abnormalities in the cells. These effects indicated the the exopolysaccharides had an antitumoral mechanism of action associated with the mitochondrial dysfunction of the treated cells. This is the first study to investigate the endophytic microorganism isolated from O. japonicas and also the first discovery of such antitumoral exopolysaccharides derived from the genus Bacillus. This provides a promising and reproducible natural product source with high therapeutic value for anticancer treatment, thereby facilitating the development of new anticancer agents.

Abstract
We used diffusion tensor imaging to characterize microstructural changes and their associations with cognition in Chinese patients with frontal lobe epilepsy (FLE). We examined 18 adult patients with FLE and 20 healthy controls. Compared with normal controls, patients with FLE had increased mean diffusivity (MD) in the right frontal lobe and decreased fractional anisotropy (FA) in both thalami. Patients with FLE also had decreased FA in the right frontal lobe that correlated with patient age at seizure onset and increased MD in the left thalamus that correlated with duration of epilepsy. Patients with FLE performed significantly worse on nearly all cognitive tasks, and there was a positive correlation between Mini-Mental Status Examination scores and FA in the left frontal lobe and the left thalamus. Our results suggest that the thalamus might be an important extrafrontal structure involved in FLE and that a longer duration of epilepsy might result in more abnormalities in the thalamus. Our results also support the hypothesis that the left frontal lobe white matter and the thalamus contribute to cognitive impairment in patients with FLE.

Abstract
Heartbeat detection is very important for retrieving the vital signs of heart functions. The morphologies and inter-beat intervals of heartbeats can reveal the condition of heart contraction. In this paper, we developed a heartbeat information integration scheme to deal with the information yielded by the energy thresholding and template match methods, which are usually used to detect the heartbeats and match the QRS, respectively. The proposed method are developed in SIMULINK 2.0 and assessed by the MIT/BIH arrhythmia database. The result demonstrated excellent sensitivity of detecting QRS and ventricular premature contraction in the proposed method.

Abstract
The coma is common in intensive care units. The bedside physical examination provides a means to measuring the neurological status, but it cannot be a continuous evaluation, whereas electroencephalogram (EEG) can reflect the immediate electrical activities of the brain. In this paper, we investigate the spectral parameters, complexity and irregular measures, and spectral entropy in the coma. Compared to the normal subject, the EEG of the coma has a dominance of slow wave, low complexity, less irregularity, and low spectral entropy. This result demonstrates the possibility to use EEG analysis for the monitoring of neurological function.
