ABSTRACT
Objective:To investigate the protective effect of racanisodamine on lung injury in mice exposed to irradiation.Methods:C57BL/6 mice were randomly divided into control group, racanisodamine group, 18 Gy irradiation group (model group) and racanisodamine combined with 18 Gy irradiation group (treatment group), with 5 mice in each group. The mice in the treatment group received racanisodamine (5 mg/kg) intraperitoneally 3 d before irradiation and contained the whole experiments. Then, single chest irradiation of 18 Gy X-rays was performed both in the model and treatment groups. The racanisodamine group and treatment group received racanisodamine intraperitoneally once a day until 6 weeks after irradiation. The mice were killed at 6 weeks after irradiation. The lung histopathology was observed by HE staining. Serum and bronchial alveolar lavage fluid (BALF) inflammatory cytokines such as TNF-α, IL-1β and IL-6 were determined by ELISA method. Cell senescence was detected by SA-β-Gal staining. The expressions of Nrf2, p-Nrf2 and p62 in lung tissue were performed by immunehistochemistry and Western blot assays.Results:Compared with the model group, the scores of HE staining were decreased ( t=8.66, P<0.01), the number of infiltrated inflammatory cells in BALF were decreased ( t=10.70, P<0.01), and protein concentration in BALF had lower levels ( t=6.75, P<0.01), the serum TNF-α, IL-1β and IL-6 were decreased significantly ( t=8.17, 4.58, 6.54, P<0.01), the activity of SA-β-gal was decreased, and the expressions of Nrf2, p-Nrf2 were enhanced ( t=6.42, 7.30, P<0.01), while the expression of p62 was reduced ( t=4.62, P<0.01) in the treatment group. Conclusions:Racanisodamine plays the protective effect of radiation-induced lung injury by alleviating inflammation associating with the activating of Nrf2-related pathway, which reversed radiation-induced cell senescence.
ABSTRACT
Wilt disease is a major disease of cultivated Salvia miltiorrhiza, which is caused by Fusarium oxysporum. Since the infection process of F. oxysporum in plants is affected by environment factors, this study was conducted to reveal the relationship between disease severity and concentration of the pathogen in plants in the infection process of F. oxysporum in seedlings of S. miltiorrhiza by pot experiments and to reveal the effects of temperature and humidity on the infection process. The results showed that, after inoculation of S. miltiorrhiza seedlings with F. oxysporum, the pathogen in different parts was detected at different time, and it was first detected in substrates. With the continuous propagation of the pathogen(4-5 d), it gradually infected the roots and stems of the seedlings, and the plants had yellowing leaves and withering. The number of the pathogen reached the maximum in each part after 7-8 d, and then gradually decreased in the later stage of the disease. The concentration of the pathogen in substrates, roots and stems of S. miltiorrhiza showed a trend of decreasing after increasing with the aggravation of the disease and reached the maximum in the samples of moderate morbidity, while the concentration in the samples of severe morbidity decreased. In addition, the infection of F. oxysporum in seedlings of S. miltiorrhiza was affected by temperature and humidity. The suitable temperature was 25-30 ℃ and the suitable humidity was 80%-90%. This study could provide guidance for the experiments on pathogenicity of F. oxysporum, screening of biocontrol bacteria and controlling of wilt.

Arbuscular mycorrhizal fungi provided is beneficial to Salvia miltiorrhiza for increasing yield, promoting the accumulation of active ingredients, and alleviating S. miltiorrhiza disease etc. However, the application of fungicides will affect the benefit of arbuscular mycorrhizal fungi and there is little research about it. This article study the effect of four different fungicides: carbendazim, polyoxin, methyl mopazine, and mancozeb on mycorrhiza benefit to S. miltiorrhiza by the infection intensity of arbuscular mycorrhizal fungi, the growth of S. miltiorrhiza, and the content of active ingredients. RESULTS:: showed that different fungicides had different effects. The application of mancozeb had the strongest inhibitory effect on the mycorrhizal benefit to S. miltiorrhiza. Mancozeb significantly reduced the mycorrhizal colonization and the beneficial effect of arbuscular mycorrhizal fungi on the growth and the accumulation of active components of S. miltiorrhiza. The application of polyoxin had no significant effect on mycorrhizal colonization. Instead, it had a synergistic effect with the mycorrhizal benefit to promoting the growth and accumulation of rosmarinic acid of S. miltiorrhiza. The inhibitory strengths of four fungicides are: mancozeb>thiophanate methyl, carbendazim>polyoxin. Therefore, we recommend applying biological fungicides polyoxin and avoid applying chemical fungicides mancozeb for disease control during mycorrhizal cultivation of S. miltiorrhiza.

3-Hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is the first rate-limiting enzyme of terpenoid biosynthesis in the mevalonic acid pathway (MVA) pathway. It is an important regulatory site in terpenoids metabolism pathway in the cytoplasm. According to the transcriptome database of Cinnamomum camphora, two HMGRs named CcHMGR1 (GenBank: MN163055) and CcHMGR2 (GenBank: MN163056) were cloned by cDNA from C. camphora. The ORF of CcHMGR1 and CcHMGR2 is composed of 1 689 bp and 1 683 bp, respectively, encoding 562 and 560 amino acids. The bioinformatics analysis of CcHMGR1 and CcHMGR2 indicated that the molecular weight of the encoded protein is 59.819 kDa and 59.397 kDa, with a theoretically isoelectric point of 8.20 and 8.61, respectively. There are 2 transmembrane structures without signal peptide existing in the encoded amino acid of CcHMGRs. The analysis of sequence alignment and phylogenetic tree showed that theCcHMGRs belonged to the HMGR family. The camphor is divided into five chemitypes, according to the main chemical compoundsin C. camphora. The results of the real time PCR indicated that the expression level of CcHMGRs in Cineol type was higher than that in Linalool type, iso-nerolidol type, Camphor type and Borneol type. CcHMGRs expressed highest in roots and lowest in branches. In this study, the cDNA full length of CcHMGRs were cloned from C. camphora for the first time. Our results revealed that the expression level of CcHMGRs were different among five chemical types and different plant tissues, and the research provides foundation for further study of the terpenoids biosynthetic pathway in C. camphora.
ABSTRACT
OBJECTIVE: To analyze the quality of life(QOL) of peasant workers with pneumoconiosis and its main influencing factors. METHODS: A typical sampling method was used to select 83 peasant workers with pneumoconiosis in two villages in Zhaotong City, Yunnan Province as the pneumoconiosis group, and 85 non-pneumoconiosis peasant workers in the same village selected as the control group. The QOL of the two groups was investigated using the Quality of Life Measurement Scale. RESULTS: The average annual family income of pneumoconiosis group was much lower and average annual expenditure of the family for disease treatment increased in 2015(P<0.01) compared with the control group. The total score of QOL and its average scores in the physical, psychological, environmental and social fields of pneumoconiosis group were lower than that of the control group(P<0.01). The multiple stepwise regression analysis results showed significant factors related to all functional domain scores of QOL in the pneumoconiosis group. For the total score of QOL, complication and ability to do housework were the significant factors. In the physical domain of QOL, only doing housework was the significant factor. In the psychological domain of QOL, complications and average annual family income were the significant factors. Marital status, doing housework and educational level were the significant factors for the social domain of QOL. The significant factors for the environmental domain of QOL were average annual family income and doing housework. CONCLUSION: The QOL of migrant workers with pneumoconiosis was poor. Complications, divorcement or widowhood reduced the quality of their lives. Higher education degree, higher average annual family income and higher ability to do housework played a positive role in promoting the QOL of peasant workers with pneumoconiosis.

Objective To screen the critical genes related to the development of esophageal squamous cell carcinoma ( ESCC ) by weighted gene co-expression network analysis ( WGCNA ) and to verify by experiments.Methods Gene expression data of ESCC were downloaded from gene expression omnibus (GEO) database based on gene chip platform ( GPL) 570, GPL571, GPL96/97 or GPL14613 platform, respectively. Meanwhile, the obtained differentially expressed genes together with gene expression data of 81 ESCC patients from the cancer genome atlas ( TCGA ) and clinical data were analyzed by WGCNA to set up co-expression networks including mRNA and microRNA ( miRNA ) . The expression of miRNA in ESCC tissues and paracancerous tissues was examined by quantitative real-time polymerase chain reaction ( RT-PCR ) .And the expression of target protein Kruppel like factor 4 ( KLF4 ) and desmocollin 2 ( DSC2 ) were detected by immunohistochemistry .After ESCC cell line ECA-109 cells were transfected with miRNA-92b-3p mimic, cell cycle was tested by flow cytometry ,the cell invasion and migration ability was measured by Transwell chamber assay and scratch-wound assay.The expression of KLF4 and DSC2 was observed by confocal laser scanning microscopy and Western blotting .The target genes were verified by luciferase assay .T-test, rank sum test, chi-square test and Pearson correlation analysis were performed for statistical analysis .Results A total of 4023 differential expression gene ( DEG) and 328 differential expression miRNA ( DEM) were screened and 11 gene modules were set up by WGCNA .Among them, the brown modules were negatively associated with tumor grade and T stage (r=-0.340 and -0.268, P=0.002 and 0.016).Meanwhile, has-miR-92b and the potential target genes KLF4 and DSC2 were all in the brown module .Furthermore, the results of RT-PCR showed the expression of miRNA-92b-3p in ESCC tissues was higher than that in paracancerous tissues (3.052(1.652, 5.371) vs.0.985(0.558, 2.032)), and the difference was statistically significant (Z=-4.021,P<0.01). The results of immunohistochemistry demonstrated that the positive rates of KLF 4 and DSC2 in ESCC tissues were 43.3％(13/30) and 20.0％(6/30), respectively, which were lower than those of paracancerous tissues (70.0％(21/30) and 63.3％(19/30)), and the differences were statistically significant (χ2 =4.344 and 1.589, both P<0.05).After ECA-109 cells were transfected with miRNA-92b-3p mimics, the percentage of cells at G0/G1 phase decreased ((63.71 ±2.83)％vs.(54.62 ±4.00)％) and the percentage of cells at the S phase and G2/M phase increased ((31.81 ±2.88)％vs.(41.20％±2.87)％, and (3.87 ±1.75)％vs. (8.10 ±1.71)％, respectively), and the differences were statistically significant (t =3.215, 4.000 and 2.998;P=0.032, 0.016 and 0.040).The invasion and migration ability of the cells were significantly improved (79.67 ±27.54 vs.280.33 ±46.18, (69.72 ±3.91)％ vs.(84.90 ±5.25)％), and the differences were statistically significant (t=6.465 and 4.019, P=0.003 and 0.016).The results of Western blotting indicated that, compared with control mimic group , the expression of KLF4 and DSC2 was both dramatically downregulated after transfected with miRNA-92b-3p mimics transfected (1.00 ±0.23 vs.0.42 ±0.03, 1.00 ±0.20 vs.0.55 ± 0.21), and differences were statistically significant (t=4.470 and 5.493, P=0.042 and 0.032).The results of luciferase assay demonstrated that miRNA-92b-3p could directly bind KLF4 and DSC2. Conclusion WGCNA is an efficient systemic biological approach by which miRNA-92b-3p is identified as a new cancer-promoting gene .
ABSTRACT

ABSTRACT
Objective The nerve-protective effect of Apoli-poprotein J ( ApoJ) in intracerebral hemorrhage ( ICH) is not yet clarified.This study aimed to explore the therapeutic effect of trans -plantation of bone marrow mesenchymal stem cells (BMSCs) carrying the ApoJ gene on intracerebral hemorrhage in rats and its possible ac -tion mechanism. Methods Rat BMSCs were isolated, cultured in vitro, and transfected with the recombinant plasmid pEGFP -N1-ApoJ mediated with lipofectamine.Ninety-six SD rats were randomly divided into groups A, B and C, and ICH models were established by two -step autologous intracranial blood injection .At 24 hours after model-ing, the rats in groups A, B, and C were transplanted with the same volume of ApoJ-transfected BMSC suspension, BMSC suspension and normal saline, respectively.At 1, 3, 5 and 7 days after transplantation, the neurofunction recovery of the rats were evaluated with modified Neurological Severity Scores (mNSS), the brain water content measured by the dry -wet weight method, and the expression level of complement component 3 (C3) in the brain tissue detected by Western blot . Results The mNSS exhibited no statistically significant differences among the three group of rats on the 1st day after transplantation (P>0.05), but was remarkably lower in group A than in B and C on the 3rd (8.13±0.99 vs 9.25±1.28 and 10.88±0.84, P<0.05), 5th (6.75±1.04 vs 8.50±1.41 and 9.75±0.89, P<0.05) and 7th day (5.63±0.52 vs 7.00±0.54 and 7.88±1.25, P<0.05), and markedly lower in group B than in C (P<0.05).The water content in the brain tissue was also significantly lower in group A than in B and C on the 1st (78.17±0.82 vs 78.83±0.56 and 80.38±0.35, P<0.05), 3rd (78.68±0.55 vs 79.12±0.26 and 81.47±0.26, P<0.05), 5th (77.00±0.58 vs 78.13±0.46 and 79.74± 0.41, P<0.05) and 7th day (75.89±0.46 vs 76.86±0.29 and 78.44±0.44, P<0.05), and remarkably lower in group B than in C (P<0.05).Western blot showed that the expression of the C 3 protein in the brain tissue was markedly decreased in group A as compared with B and C on the 1st (0.096±0.011 vs 0.212±0.014 and 0.440±0.006, P<0.05), 3rd (0.083±0.005 vs 0.164±0.013 and 0.604± 0.011, P<0.05), 5th (0.064±0.009 vs 0.105±0.010 and 0.333±0.010, P<0.05), 7th day (0.045±0.007 vs 0.091±0.004 and 0.141± 0.003, P<0.05), and significantly lower in group B than in C (P<0.05). Conclusion ApoJ can promote the recovery of the neuro-logical function of ICH rats by inhibiting complement activation -mediated secondary brain damage and alleviating cerebral edema .
ABSTRACT
By comparing the effects of soil pH on the efficiency of mycorrhizal symbiosis on Salvia miltiorrhiza， the study is aimed to provide guidance for the use of mycorrhiza in the cultivation of S. miltiorrhiza. In this experiment, the inoculant treated and the non-inoculant treated control were grown in different soil pH. The data was collected after 60 days of cultivation including rate of mycorrhizal infection, biomass, and three chemical constituents with known medicinal action. The results showed that Glomus versiforme was more apt to infect S. miltiorrhiza (F>94.00%; M>69.45%; m>73.66%) and promote the growth of S. miltiorrhiza under pH 5-9 soil. The mycorrhizal contribution to the growth of S. miltiorrhiza was the highest when grown in pH 8 soil. Plants grown with mycorrhiza in pH 8 soil had above-ground biomass more than 2 times and root biomass more than 5 times. The uninoculated plants grew better under acidic and neutral conditions, but the inoculated plants grew better under alkaline (pH 8) conditions. This result showed mycorrhiza can play a role in the adaptability of S. miltiorrhiza to the environment. Inoculation of mycorrhiza significantly increased the accumulation of rosmarinic acid, salvianolic acid B, and dihydrotanshinone by 6.59,5.03 and 2.20-folds. Based on our results alkaline soil (pH 8) is most suitable for the cultivation of S. miltiorrhiza by inoculation with the mycorrhiza G. versiforme.
