As a traditional medical intervention in Asia and a complementary and alternative medicine in western countries, Traditional Chinese Medicine (TCM) is capturing worldwide attention in life science field. Traditional Chinese Medicine Integrated Database (TCMID), which was originally launched in 2013, was a comprehensive database aiming at TCM’s modernization and standardization. It has been highly recognized among pharmacologists and scholars in TCM researches. The latest release, TCMID 2.0 (http://www.megabionet.org/tcmid/), replenished the preceding database with 18 203 herbal ingredients, 15 prescriptions, 82 related targets, 1356 drugs, 842 diseases and numerous new connections between them. Considering that chemical changes might take place in decocting process of prescriptions, which may result in new ingredients, new data containing the prescription ingredients was collected in current version. In addition, 778 herbal mass spectrometry (MS) spectra related to 170 herbs were appended to show the variation of herbal quality in different origin and distinguish genuine medicinal materials from common ones while 3895 MS spectra of 729 ingredients were added as the supplementary materials of component identification. With the significant increase of data, TCMID 2.0 will further facilitate TCM’s modernization and enhance the exploration of underlying biological processes that are response to the diverse pharmacologic actions of TCM.

Magnetic random access memories based on the spin transfer torque phenomenon (STT-MRAMs) have become one of the leading candidates for next generation memory applications. Among the many attractive features of this technology are its potential for high speed and endurance, read signal margin, low power consumption, scalability, and non-volatility. In this paper, we discuss our recent results on perpendicular STT-MRAM stack designs that show STT efficiency higher than 5 kBT/μA, energy barriers higher than 100 kBT at room temperature for sub-40 nm diameter devices, and tunnel magnetoresistance higher than 150%. We use both single device data and results from 8 Mb array to demonstrate data retention sufficient for automotive applications. Moreover, we also demonstrate for the first time thermal stability up to 400 °C exceeding the requirement of Si CMOS back-end processing, thus opening the realm of non-volatile embedded memory to STT-MRAM technology.

Members of the plant-specific IQ67-domain (IQD) protein family are involved in various aspects of normal plant growth and developmental processes as well as basal defence response. Although hundreds of IQD proteins have been identified, only a small number of IQDs have been functionally characterized. Moreover, no systematic study has been performed on moso bamboo. In this study, we performed for the first time a genome-wide identification and expression analysis of the IQD gene family in moso bamboo. We identified 29 non-redundant PeIQD encoding genes. Analysis of the evolutionary patterns and divergence revealed that the IQD genes underwent a large-scale event around 12 million years ago and the division times of IQD family genes between moso bamboo and rice, and, between moso bamboo and Brachypodium, were found to be 20–35 MYA and 25–40 MYA, respectively. We surveyed the putative promoter regions of the PeIQD genes, which showed that largely stress-related cis-elements existed in these genes. The expression profiles of the IQD genes shed light on their functional divergence. Additionally, a yeast two-hybrid assay proved that PeIQD8 can interact with PeCaM2 and that IQ or I in the IQ motif is required for PeIQD8 to combine with CaM2.

29 Moso bamboo VQ proteins were genome-wide identified for the first time, and bioinformatics analysis was performed to investigate phylogenetic relationships and evolutionary divergence. The qRT-PCR data show that PeVQ genes response to different stress treatments. Accumulating evidence suggests that VQ motif-containing proteins in rice (Oryza sativa), Arabidopsis (Arabidopsis thaliana), and maize (Zea mays) play fundamental roles in response to various biotic and abiotic stresses. However, little is known about the functions of VQ family proteins in Moso bamboo (Phyllostachys edulis). In this study, we performed a genome-wide bioinformatic analysis and expression profiling of PeVQ genes. A total of 29 VQ genes was identified and divided into seven subgroups (I-VII) based on phylogenetic analysis. Gene structure and conserved motif analysis revealed that 25 of 29 VQ genes contained no introns. Multiple sequence alignment showed that Moso bamboo VQ motif-containing proteins contained five variations of the conserved motif. The time of duplication and divergence of Moso bamboo from rice and maize was calculated using K analysis. A heat map was generated using microarray data from 29 Moso bamboo VQ genes suggesting that these genes were expressed in different tissues or developmental stages. Quantitative real-time PCR (qRT-PCR) and promoter analysis indicated that PeVQ genes were differentially regulated following treatment with polyethylene glycol, abscisic acid and salicylic acid. Our results provide a solid foundation for further research of the specific functions of VQ motif-containing proteins in Moso bamboo.

Doxorubicin (DOX), a potent broad‑spectrum chemotherapeutic agent used for the treatment of several types of cancer, is largely limited due to its serious side effects on non‑target organs. Thus, the present study aimed to investigate whether berberine (Ber), an isoquinoline alkaloid, could reduce DOX‑induced acute hepatorenal toxicity in rats. Fifty rats were randomly divided into five groups: i) Control group, ii) DOX group, iii) DOX+Ber (5 mg kg) group; iv) DOX+Ber (10 mg kg), and v) DOX+Ber (20 mg kg) group. In the tests, body weight, organ index, general condition and mortality were observed. In addition, the serum levels of alanine transaminase (ALT), aspartate aminotransferase (AST), total cholesterol (TCHO) and blood urea nitrogen (BUN) were determined to evaluate hepatorenal function. Hepatorenal toxicity was further assessed using hematoxylin and eosin stained sections. Furthermore, the levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and malondialdehyde (MDA) in rat serum or tissue homogenate were also assessed to determine the mechanisms of action. Results suggested that pretreatment with Ber ameliorated the DOX‑induced liver and kidney injury by lowering the serum ALT, AST, TCHO and BUN levels, and the damage observed histologically, such as hemorrhage and focal necrosis of liver and kidney tissues induced by DOX were also attenuated by Ber. Furthermore, Ber also exerted certain antioxidative properties through reversing the changes in the levels of MDA, SOD, GSH and MDA induced by DOX. These findings indicate that Ber has protective effects against DOX‑induced acute hepatorenal toxicity in rats. Combination of Ber with DOX is a novel strategy that has the potential for protecting against DOX‑induced hepatorenal toxicity in clinical practice.
