Oxidative Damage to BV2 Cells by Trichloroacetic Acid: Protective Role of Boron via the p53 Pathway / 生物医学与环境科学（英文）

This study aimed to investigate the neurotoxicity induced by trichloroacetic acid (TCA) and the possible protective mechanisms of boron (B). Mouse BV2 cells were treated with TCA (0, 0.39, 0.78, 1.56, 3.12, 6.25, or 12.5 mmol/L) and B (0, 7.8, 15.6, 31.25, 62.5, 125, 500, or 1,000 mmol/L) for 3 h and 24 h, respectively. Then, reactive oxygen species, and supernatant proinflammatory cytokine and protein levels were analyzed after 24 h of combined exposure. Beyond the dose-dependent decrease in the cellular viability, it clearly increased after B supplementation ( P < 0.05). Moreover, B decreased oxidative damage, and significantly down-regulated IL-6 levels and up-regulated TNF-β production ( P < 0.05). B also decreased apoptosis via the p53 pathway. The present findings indicated that TCA may induce oxidative damage, whereas B mitigates these adverse effects by decreasing cell apoptosis.

Identification of medicinal plants within the Apocynaceae family using ITS2 and psbA-trnH barcodes / 中国天然药物

To ensure the safety of medications, it is vital to accurately authenticate species of the Apocynaceae family, which is rich in poisonous medicinal plants. We identified Apocynaceae species by using nuclear internal transcribed spacer 2 (ITS2) and psbA-trnH based on experimental data. The identification ability of ITS2 and psbA-trnH was assessed using specific genetic divergence, BLAST1, and neighbor-joining trees. For DNA barcoding, ITS2 and psbA-trnH regions of 122 plant samples of 31 species from 19 genera in the Apocynaceae family were amplified. The PCR amplification for ITS2 and psbA-trnH sequences was 100%. The sequencing success rates for ITS2 and psbA-trnH sequences were 81% and 61%, respectively. Additional data involved 53 sequences of the ITS2 region and 38 sequences of the psbA-trnH region were downloaded from GenBank. Moreover, the analysis showed that the inter-specific divergence of Apocynaceae species was greater than its intra-specific variations. The results indicated that, using the BLAST1 method, ITS2 showed a high identification efficiency of 97% and 100% of the samples at the species and genus levels, respectively, via BLAST1, and psbA-trnH successfully identified 95% and 100% of the samples at the species and genus levels, respectively. The barcode combination of ITS2/psbA-trnH successfully identified 98% and 100% of samples at the species and genus levels, respectively. Subsequently, the neighbor joining tree method also showed that barcode ITS2 and psbA-trnH could distinguish among the species within the Apocynaceae family. ITS2 is a core barcode and psbA-trnH is a supplementary barcode for identifying species in the Apocynaceae family. These results will help to improve DNA barcoding reference databases for herbal drugs and other herbal raw materials.

Endemic plants for medicine use in China / 中国中药杂志

Based on plant species databases, species lists and literature records, general situation of the Chinese medicinal endemic plant (vascular plant) has been systematically summarized, and its quantity and distribution characteristics of Chinese medicinal endemic plants are presented in this paper. The results showed that 3 150 endemic species are Chinese medicinal plants belonging to 785 genera in 153 families, which includes 38 species of 22 genera in 12 families of pteridophyta, 42 species of 14 genera in7 families of gymnosperms, and 3 070 species of 749 genara in 134 families of angiosperms. The top four families involving medicinal endemic species are Asteraceae (218 species), Ranunculaceae (182 species), Labiatae (151 species), and Liliaceae (133 species). The top four provincial administration distributed medicinal endemic species are Sichuan (1 568 species), Yunnan (1 533 species), Guizhou (955 species) and Hubei (930 species).On the regional scale, the most abundant one is the southwest region (2 465 species), followed by the central region (1 226 species) and the northwest region (949 species). Localization characteristics for domestication and artificial cultivation of medicinal endemic species are more prominent due to their narrower and limited distribution areas, indicating it is possible for these species acting as local potential resource for reasonable economic development.
