Objective To explore the roles of Th17 cells in paraquat-induced acute lung injury(ALI)in a murine models through investigating the expression of Th17 type cytokine IL-17 and the specific transcription factor of Th17 cells-RORγt mRNA. Methods Male Kunming mice were randomly divided into the normal control group and the poisoned group. The ALI model induced by PQ poisoning was produced by intraperitoneal injection PQ solu-tion (20 mg/kg),and the normal control group was given normal saline solution with the same volume. After treatment for 48 hours,the animals were sacrificed. H&E staining and TUNEL staining were done to measure histo-logical changes and apoptosis. Serum level of Th17 related-cytokines was assayed by ELISA. The mRNA ex-pression of RORγt and the protein expression of IL-17 in the lung tissue were detected by real time-PCR assay and western blot,respectively. Results Compared with the normal control group,the lung inflammation and apopto-sis were significantly higher in the poisoned group. The serum level of IL-17A was significantly increased (P <0.05) and the lung parenchyma RORγt mRNA and IL-17 protein levels were significantly increased. Conclu-sion IL-17 plays an important role in the pathogenesis of ALI induced by paraquat poisoning.

Abstract
Sedentary behaviors have gradually become the most popular “activity” in daily life. Too many non essential sedentary behaviors, such as the excessive consumption of video entertainment, pose a serious threat to health and generate a heavy burden of disease to society. There is an urgent need to raise awareness and take measures to curb sedentary behaviors. Childhood is a period of opportunity, during which caregivers can shape the behavioral habits of children and encourage them to adopt favorable behaviors, which can directly affect the physical health of the nation s future population. Recently, the government has successively promulgated relevant policies to encourage students sports and labor education to livelihood. It is particularly critical that such policies are implemented in practice.

In order to find out the composition, characteristics and traditional utilization characteristics of Dai medicine and promote the rational protection, inheritance and utilization of the resources and traditional knowledge of Dai medicine in China, the resources of traditional Dai medicine have been investigated systematically and the traditional knowledge of Dai medicine have been analyzed in the article. We found out that there were altogether 1 077 kinds of traditional Dai medicine in China and among which 272 were the first time recorded in the condition of Dai folk medical uses. There were 1 053 plant medicines which belong to 169 family and 694 genus. These plant medicines mainly distributed in the southern, west southern and east southern area of Yunnan province, the southern area of Guangxi, Guangdong, Guizhou, Sichuan, Fujian province and tropical, subtropical district as Taiwan, and more than 94.49% plant medicines could be found in Yunnan province. From the point of plant life form, they were major herbaceous or shrubby plants; When it is used as medicinal part, root and rhizome of plants account for the highest proportion, the next were whole plant and leaves. From nature, flavor and channel tropism points of view, the largest proportion of Dai medicines were cool, bitter-tasted and possesses water element. In terms of treatment of disease types, most of the drugs can treat gastrointestinal diseases, next were drugs that could be used to treat upper respiratory infection, traumatological and rheumatic diseases, urinary infection, gynecological diseases, hepatopathy, puerperium fever and diseases caused by poisonous insects and beast of prey bite. The study revealed that the resources of traditional Dai medicine and traditional knowledge of application were abundant in China, but the resources of traditional Dai medicine and traditional knowledge of application were faced with the risk of gradually reduce and loss. The article suggested that we should take measures to strengthen the study of protection and utilization of important traditional Dai medicine and endangered resources along with the protection and transmission of traditional knowledge of Dai nationalistic medicine.

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.
