Abstract
The current study analyzed the mutation rate of BRAFV600E in papillary thyroid carcinoma patients and the correlation between BRAFV600E mutation and aggressive biological behavior of papillary thyroid carcinoma. A total of 160 patients with papillary thyroid carcinoma who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from October 2020 to November 2021 were retrospectively included. All patients underwent BRAFV600E gene detection. There were 37 males and 123 females, with a mean age of (46.5±11.1) years. The mutation rate of BRAFV600E was 86.3% (138/160). There was no significant correlation between the mutation of BRAFV600E and aggressive factors such as age (P=0.917), single focal/multifocal tumor (P=0.673), tumor size (P=0.360), tumor invasion (P=0.150) and regional lymph node metastasis (P=0.406). Therefore, for papillary thyroid cancer, mutations in a single gene like BRAFV600E fail to determine more active diagnosis and treatment.

Abstract
BACKGROUND Tomato chlorosis virus (ToCV) is a semi-persistent plant virus that is primarily transmitted by the whitefly Bemisia tabaci (Hemiptera: Aleyrodidae). It causes a serious disease that lowers tomato yield. Insulin-like peptide (ILP), an insulin homolog, regulates trehalose metabolism in a variety of insects. In a previous study, we discovered that trehalose metabolism is required for whiteflies to transmit ToCV effectively. Furthermore, transcriptome sequencing revealed that the BtILP7 gene was highly expressed in B. tabaci infected with ToCV. Therefore, the whitefly ILP7 gene may facilitate the transmission of ToCV and be an attractive target for the control of whiteflies and subsequently ToCV. RESULTS The ToCV content in B. tabaci MED was found to be correlated with BtILP7 gene expression. Subsequent RNA interference (RNAi) of the BtILP7 gene had a significant impact on B. tabaci MED's trehalose metabolism and reproductive capacity, as well as ability to transmit ToCV. CONCLUSIONS These results indicate that the BtILP7 gene was closely related to ToCV transmission by regulating trehalose metabolism and reproduction behavior, thus providing a secure and environmentally friendly management strategy for the control of whiteflies and ToCV-caused disease. © 2022 Society of Chemical Industry.

Abstract
Tomato disease is an important disease affecting agricultural production, and the combined infection of tomato chlorosis virus (ToCV) and tomato yellow leaf curl virus (TYLCV) has gradually expanded in recent years, but no effective control method has been developed to date. Both viruses are transmitted by Bemisia tabaci Mediteranean (MED). Previously, we found that after B. tabaci MED was fed on ToCV-and TYLCV-infected plants, the transmission efficiency of ToCV was significantly higher than that on plants infected only with ToCV. Therefore, we hypothesize that co-infection could enhance the transmission rates of the virus. In this study, transcriptome sequencing was performed to compare the changes of related transcription factors in B. tabaci MED co-infected with ToCV and TYLCV and infected only with ToCV. Hence, transmission experiments were carried out using B. tabaci MED to clarify the role of cathepsin in virus transmission. The gene expression level and enzyme activity of cathepsin B (Cath B) in B. tabaci MED co-infected with ToCV and TYLCV increased compared with those under ToCV infection alone. After the decrease in cathepsin activity in B. tabaci MED or cathepsin B was silenced, its ability to acquire and transmit ToCV was significantly reduced. We verified the hypothesis that the relative expression of cathepsin B was reduced, which helped reduce ToCV transmission by B. tabaci MED. Therefore, it was speculated that cathepsin has profound research significance in the control of B. tabaci MED and the spread of viral diseases.

Abstract
Photosynthetic bacteria are beneficial to plants, but knowledge of photosynthetic bacterial community dynamics in field crops during different growth stages is scarce. The factors controlling the changes in the photosynthetic bacterial community during plant growth require further investigation. In this study, 35 microbial community samples were collected from the seedling, flowering, and mature stages of tomato, cucumber, and soybean plants. 35 microbial community samples were assessed using Illumina sequencing of the photosynthetic reaction center subunit M (pufM) gene. The results revealed significant alpha diversity and community structure differences among the three crops at the different growth stages. Proteobacteria was the dominant bacterial phylum, and Methylobacterium, Roseateles, and Thiorhodococcus were the dominant genera at all growth stages. PCoA revealed clear differences in the structure of the microbial populations isolated from leaf samples collected from different crops at different growth stages. In addition, a dissimilarity test revealed significant differences in the photosynthetic bacterial community among crops and growth stages (P<0.05). The photosynthetic bacterial communities changed during crop growth. OTUs assigned to Methylobacterium were present in varying abundances among different sample types, which we speculated was related to the function of different Methylobacterium species in promoting plant growth development and enhancing plant photosynthetic efficiency. In conclusion, the dynamics observed in this study provide new research ideas for the detailed assessments of the relationship between photosynthetic bacteria and different growth stages of plants.

Abstract
BACKGROUND Thiamethoxam is widely used to control pests in Chinese kale, popularly consumed leafy vegetables. The potential risk to the environment and human health has aroused much public concern. Therefore, it is important to investigate the degradation behavior, residue distribution and dietary risk assessment of thiamethoxam in Chinese kale. RESULTS A sensitive analytical method for determination of thiamethoxam and its metabolite clothianidin residue in Chinese kale was established and validated through a quick, easy, cheap, effective, rugged, and safe (QuEChERS) technique with ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The recoveries were 85.4-101.2% for thiamethoxam and 79.5-108.1% for clothianidin, with the relative standard deviations (RSDs) of 0.9-10.2% and 1.8-6.0%, respectively. For the dissipation kinetics, the data showed that thiamethoxam in Chinese kale was degraded with the half-lives of 4.1 to 4.5 days. In the terminal residue experiments, the residues of thiamethoxam were 0.017-0.357 mg kg-1 after application 2-3 times with a preharvest interval (PHI) of 7 days under the designed dosages. The chronic and acute dietary exposure assessment risk quotient (RQ) values of thiamethoxam in Chinese kale for different Chinese consumers were 0.08-0.19% and 0.05-0.12%, respectively, and those of clothianidin were 0.01-0.04% and 0.02-0.04%, respectively, all of the RQ values were lower than 100%. CONCLUSION Thiamethoxam in Chinese kale was rapidly degraded following first-order kinetics models. The dietary risk of thiamethoxam and clothianidin through Chinese kale was negligible to consumers. The results from this study are important reference for Chinese governments to developing criteria for the safe and rational use of thiamethoxam, setting maximum residue levels (MRLs), monitoring the quality safety of agricultural products and protecting consumer health. © 2021 Society of Chemical Industry.

Abstract
The risk of plague epidemics and relapse of various types of plague foci persists in Inner Mongolia Autonomous Region. For Marmota sibirica plague foci, the animal plague has not been found but antibody has been detected positive. Nowadays, Marmota sibirica has been increasing in population and distribution in China. In bordering countries Mongolia and Russia, the animal plague has been continuously prevalent. For Spermophilus dauricus plague foci, the animal plague has been taken place now and then. Compared to the above foci, the animal plague is most prevalent in Meriones unguiculatus plague foci and frequently spread to humans. Due to higher strain virulence and historical disaster in Marmota sibirica plague foci and Spermophilus dauricus plague foci, plague prevention and control should be strengthened on these foci. In addition to routine surveillance, epidemic dynamics need to be further monitored in these two foci, in order to prevent their relapse and spread to humans.

Abstract
Objective: To investigate the diagnosis, treatment and prognosis of ureteral endometriosis with hydronephrosis. Methods: A retrospective study was performed of 92 cases diagnosed as ureteral endometriosis with surgery confirmed in Peking University First Hospital from January 2000 to January 2021. Results: The incidence of ureteral endometriosis was 0.9% (92/10 222), with an average age of (40.0±6.0) years. Among 92 cases, urological symptoms and pelvic pain including dysmenorrheal, periodic abdominal pain were the main forms of clinical characteristics, while 11 patients (12%, 11/92) were asymptomatic. All patients with ureteral endometriosis had hydronephrosis and hydroureter before surgery, hydronephrosis were left sided in 48 (52%, 48/92) patients, right sided in 39 (42%, 39/92) patients, both sided in 5 (5%,5/92) patients. The distal and middle sections of ureteral obstructions existed in 73 (79%, 73/92) patients and 19 (21%, 19/92) patients, respectively. Out of the 92 ureteral lesions 71 (77%, 71/92) patients were extrinsic lesions, 21 (23%, 21/92) patients presented intrinsic lesions. Of the 38 cases who took preoperative radionuclide renal dynamic imaging examination, there were 6 (16%, 6/38) cases of mildly damaged, 7 (18%, 7/38) cases of moderately dameged, 14 (37%, 14/38) cases of severely damaged, and 11 (29%, 11/38) cases of normal renal function. Laparotomy was decided in 25 (27%, 25/92) patients, and laparoscopic surgery in 67 (73%, 67/92) patients. In cases of ureteral surgery, ureterolysis, partial ureteral resection and ureterocystoneostomy, partial ureteral resection and end-to-end ureteral anastomosis and nephroureterectomy were undertaken in 52 (57%, 52/92), 20 (22%, 20/92), 12 (13%, 12/92) and 8 (9%, 8/92) patients separately. The median follow up was 108 months (range: 6 to 240 months). During the follow-up period, 68 (87%, 68/78) patients took urinary ultrasound after surgery, and 60 (88%, 60/68) cases of hydronephrosis disappeared, and 8 (12%, 8/68) cases were better than before. Conclusion: Most of the patients with ureteral endometriosis are impaired with renal function, and early surgical treatment could effectively relieve urinary obstruction and promote the recovery of renal function.

Abstract
BACKGROUND Tomato chlorosis virus (ToCV) is mainly vectored by Bemisia tabaci in China, which has a worldwide distribution, and greatly reduces the yields of tomato and other vegetables. At present, control of ToCV has been focused mainly by the use of insecticides to control whitefly populations. Transcriptome sequencing showed high expression of the B. tabaci Bta11975 gene, an α-glucosidase (AGLU) during ToCV acquisition by whitefly Mediterranean (MED) species. To investigate the role of Bta11975 gene in ToCV acquisition and transmission by B. tabaci MED, we used RNA interference (RNAi) to reduce the expression of the Bta11975 gene. RESULTS The relative expression of the Bta11975 gene was correlated with the ToCV content in B. tabaci. The AGLU is highly expressed in primary salivary gland and gut. After the Bta11975 gene was silenced, the gene expression of B. tabaci was reduced and B. tabaci mortality was increased. Besides, ToCV acquisition by B. tabaci at 48 and 72 h AAP was reduced, and ToCV transmission was significantly reduced by 25 or 50 of B. tabaci. CONCLUSIONS These results indicate that suppression of expression of the Bta11975 gene in B. tabaci MED by RNAi can reduce acquisition and transmission of ToCV by B. tabaci MED.

Abstract
Heavy metal pollution in rice fields leads to huge losses in rice yield every year and is thus of increasing concern. Therefore, it is important to understand the changes in the microecology and physicochemical properties of paddy soil under different levels of cadmium pollution. The purpose of this study was to investigate the response of the photosynthetic bacterial community in paddy soil to different cadmium pollution levels using 16S sequencing technology. The results showed that pH, total cadmium, and available cadmium content decreased gradually with the increase in cadmium pollution. The soil α diversity was slightly different in the high cadmium (Cd), medium Cd, and low Cd groups; however, the enriched photosynthetic populations and photosynthetic bacterial communities were significantly different among these groups. The effective connections between photosynthetic bacterial species in the high Cd group were significantly greater than those in the medium and low Cd groups, the connections were closer, and the density was higher. Alkaline nitrogen, pH, available (P/K), total (N/P), organic matter, total cadmium, and available cadmium were important factors affecting the photosynthetic bacterial community and were significantly correlated with the photosynthetic bacterial community, explaining 59.90% of the variation in the photosynthetic bacterial community. Effective Cd content was significantly positively correlated with Methylorubrum populi, Methylorubrum extorquens, Methylobacterium sp. Leaf125, and Rhodopseudomonas sp. AAP120 (R>0.05, P<0.05). This study will provide a theoretical basis for the microbial remediation of cadmium contamination in paddy fields. This study is important for understanding the effects of cadmium pollution on specific functional microbial populations in paddy soils.

Abstract
Tomato chlorosis virus (ToCV), is one of the most devastating cultivated tomato viruses, seriously threatened the growth of crops worldwide. As the vector of ToCV, the whitefly Bemisia tabaci Mediterranean (MED) is mainly responsible for the rapid spread of ToCV. The current understanding of tomato plant responses to this virus and B. tabaci is very limited. To understand the molecular mechanism of the interaction between tomato, ToCV and B. tabaci, we adopted a next-generation sequencing approach to decipher miRNAs and mRNAs that are differentially expressed under the infection of B. tabaci and ToCV in tomato plants. Our data revealed that 6199 mRNAs were significantly regulated, and the differentially expressed genes were most significantly associated with the plant-pathogen interaction, the MAPK signaling pathway, the glyoxylate, and the carbon fixation in photosynthetic organisms and photosynthesis related proteins. Concomitantly, 242 differentially expressed miRNAs were detected, including novel putative miRNAs. Sly-miR159, sly-miR9471b-3p, and sly-miR162 were the most expressed miRNAs in each sample compare to control group. Moreover, we compared the similarities and differences of gene expression in tomato plant caused by infection or co-infection of B. tabaci and ToCV. Taken together, the analysis reported in this article lays a solid foundation for further research on the interaction between tomato, ToCV and B. tabaci, and provide evidence for the identification of potential key genes that influences virus transmission in tomato plants.

Abstract
OBJECTIVE To explore the dynamic expression of programmed cell death-1 (PD-1) and its ligand PD-L1 at the maternal-fetal interface of mice post-infection with Toxoplasma gondii at early pregnancy and examine its interaction with interferon-γ (IFN-γ). METHODS A total of 20 mice at day 0 of pregnancy were randomly assigned into 4 groups, including the 12-day pregnancy control group (12 dpn group), 12-day pregnancy and infection group (12 dpi group), 18-day pregnancy control group (18 dpn group) and 18-day pregnancy and infection group (18 dpi group), respectively. On the 6th day of the pregnancy, mice in the 12 dpi and 18 dpi groups were injected intraperitoneally with 150 tachyzoites of the T. gondii PRU strain, while mice in the 12 dpn and 18 dpn groups were injected with the same volume of PBS. All mice in the four groups were sacrificed on 12th and 18th day of the pregnancy, and the number of placenta and fetus was counted and the weight of placenta and fetus was measured. Then, the placental and uterine tissues of the pregnant mice in each group were sampled for pathological examinations. The mRNA expression of PD-1, PD-L1, T. gondii surface antigen SAG-1 and IFN-γ genes was quantified using a quantitative real-time PCR (qPCR) assay, and the correlation between PD-1 and IFN-γ expression was examined. In addition, the 12 dpn group, 12 dpi group, 18 dpn group, 18 dpi group, PBS negative control of the 12 pdi group and PBS negative control of the 18 dpi group were assigned, and the PD-1 expression was determined in the uterine and placenta tissues of the pregnant mice. RESULTS Adverse pregnant outcomes were seen in mice in the 12 dpi and 18 dpi groups, including placental dysplasia and fetal maldevelopment, and the placental weights and fetal body weights were significantly lower in mice in the 12 dpi and 18 dpi groups than those in the 12 dpn and 18 dpn groups (t = 5.52, 11.44, 12.63 and 11.67, all P < 0.01). The histopathological examinations showed that the decidua and junctional regions of the placental tissues were loosely connected in the 12 dpi and 18 dpi groups, and a large number of inflammatory cells infiltration and congestion were seen in the placental and uterine tissues. qPCR assay detected significant differences in PD-1, PD-L1, IFN-γ and SAG-1 expression in the placental and uterine tissues among the 12 dpn, 12 dpi, 18 dpn and 18 dpi groups (F = 22.48, 51.23, 9.61, 47.49, 16.08, 21.52, 28.66 and 238.90, all P < 0.05), and the PD-1, PD - L1, IFN - γ and SAG - 1 expression was all significantly higher in the placental and uterine tissues of mice in the 12 dpi group than in the 12 dpn group (all P values < 0.05). The PD-1 and PD-L1 expression was significantly lower in the placental tissues of mice in the 18 dpi group than in the 18 dpn group (all P values < 0.05), and the IFN-γ and SAG-1 expression was significantly higher in the placental and uterine tissues of mice in the 18 dpi group than in the 18 dpn group (all P values < 0.05), while the PD-1 and PD-L1 expression was significantly lower in the placental and uterine tissues of mice in the 18 dpi group than in the 12 dpi group (all P values < 0.05). Immunohistochemical staining showed PD-1 expression in the inflammatory cells of the placental tissues of mice in the 12 dpi group, and no apparent PD-1 expression in the 18 dpi group, while strongly positive PD-1 expression was found in the uterine epithelium of mice in the 12 dpi group, and mildly strong expression was in the 18 dpi group. In addition, the IFN-γ mRNA expression was positively correlated with the PD-1 mRNA expression in placental (rs = 0.99, P < 0.01) and uterine tissues of mice in the 12 dpi group (rs = 0.97, P < 0.01) and in placental (rs = 0.82, P < 0.01) and uterine tissues of mice in the 18 dpi group (rs = 0.81, P < 0.01). CONCLUSIONS Following T. gondii infection at early pregnancy, the PD-1 and PD-L1 expression shows a remarkable rise at middle pregnancy and a reduction at late pregnancy in placental and uterine tissues of mice, which appears the same tendency with IFN-γ expression during the same time period, and PD-1 expression positively correlates with IFN-γ expression. The dynamic expression of PD-1 and PD-L1 on the maternal-fetal interface of mice may be mutually mediated by IFN-γ induced by T. gondii infection.

Abstract
OBJECTIVE To investigate the expression and possible role of hypoxia-inducible factor-1 (HIF-1) at the maternal-fetal interface following Toxoplasma gondii infection during early pregnancy. METHODS Twenty pregnant C57BL/6 mice, each weighing 16 to 20 g, were randomly divided into 4 groups, including the 12-d control group, 12-d infection group, 18-d control group and 18-d infection group. Mice in the 12-d and 18-d infection groups were injected intraperitoneally with 150 tachyzoites of the T. gondii PRU strain on day 6 of pregnancy, while mice in the 12-d control and 18-d control groups were injected with the same volume of phosphate buffered saline (PBS). Mice in the control and infection groups were sacrificed on days 12 and 18 of pregnancy, and the placental and uterine specimens of the pregnant mice in each group were sampled for pathological examinations. The mRNA expression of HIF-1α, HIF-1β and vascular endothelial growth factor (VEGF) was quantified using quantitative fluorescent real-time PCR (qPCR) assay in the placental and uterine specimens, and the correlation between HIF-1α and VEGF mRNA expression was examined. In addition, and the HIF-1α expression was detected using immunohistochemical staining in the placental and uterine specimens of pregnant mice. RESULTS Compared with the 12-d and 18-d control groups, adverse pregnant outcomes were observed in mice in 12-d and 18-d infection groups, such as teratism and placental dysplasia. HE staining showed swelling and blood stasis of cells, sinusoid reduction and inflammatory cell infiltration in the labyrinth area of the placenta specimens of mice in 12-d and 18-d infection groups relative to 12-d and 18-d control groups, and columnar epithelial cell injury and inflammatory cell infiltration were seen in the mouse uterine specimens in both infection groups. qPCR assay detected significantly higher HIF-1α (F = 132.6, P < 0.05) and HIF-1β mRNA expression (F = 286.9, P < 0.05) in the placental specimens and lower HIF-1α (F = 111.5, P < 0.05) and HIF-1β mRNA expression (F = 55.2, P < 0.05) in the uterine specimens in the 12-d infection group than in the 12-day control group, and significantly lower HIF-1α and HIF-1β mRNA expression was detected in the placental and uterine specimens in the 18-d infection group than in the 18-day control group (F = 215.8, 418.9, 156.8 and 200.1; all P values < 0.05). Significantly lower VEGF-A (F = 426.2, P < 0.05), VEGF-B (F = 104.6, P < 0.05) and VEGF-C mRNA expression (F = 566.9, P < 0.05) in the placental specimens and higher VEGF-A (F = 426.2, P < 0.05), VEGF-B (F = 104.6, P < 0.05) and VEGF-C mRNA expression (F = 566.9, P < 0.05) in the uterine specimens were detected in the 12-d infection group than in the 12-d control group, and higher VEGF-A, VEGF-B and VEGF-C mRNA expression was found in the placental and uterine specimens in the 18-d infection group than in the 18-d control group (F = 521.9, 100.6, 275.9, 224.6, 108.2 and 333.4; all P values < 0.05). Immunohistochemical staining showed strongly and mildly positive HIF-1α expression in the mouse placental labyrinth area in the 12-d and 18-d infection groups relative to 12-d and 18-d control groups, while no HIF-1α expression was detected in mouse uterine specimens. CONCLUSIONS HIF-1α expression appears a tendency towards a rise in the second trimester and a reduction in the third trimester in mice following T. gondii infection during early pregnancy, which is contrary to the changing tendency of VEGF-A, VEGF-B, and VEGF-C expression. It is hypothesized that HIF-1α inhibits placental angiogenesis in mice during pregnancy through suppressing VEGF expression, resulting in adverse pregnant outcomes.

Abstract
Neural precursor cells-expressed developmentally down-regulated protein-8 (NEDD8) is one of the important members of the ubiquitin family, which plays an important role in maintaining cell stability, cell cycle regulation, signal transduction, transcription, and translation, DNA repair, and tumorigenesis through covalently bound substrates (also known as neddylation modification). In recent years, studies have found that the dysfunction of NEDD8 and its related enzymes is common in liver diseases, and is widely involved in the biological processes of hepatitis, liver fibrosis, proliferation, invasion, apoptosis and autophagy of liver cancer cells. This article focuses on the research progress of NEDD8 in liver diseases.

Abstract
BACKGROUND Most plant viruses rely on vectors for their transmission and spread. One of the outstanding biological questions concerning the vector-pathogen-symbiont multi-trophic interactions is the potential involvement of vector symbionts in the virus transmission process. Here, we used a multi-factorial system containing a non-persistent plant virus, cucumber mosaic virus (CMV), its primary vector, green peach aphid, Myzus persicae, and the obligate endosymbiont, Buchnera aphidicola to explore this uncharted territory. RESULTS Based on our preliminary research, we hypothesized that aphid endosymbiont B. aphidicola can facilitate CMV transmission by modulating plant volatile profiles. Gene expression analyses demonstrated that CMV infection reduced B. aphidicola abundance in M. persicae, in which lower abundance of B. aphidicola was associated with a preference shift in aphids from infected to healthy plants. Volatile profile analyses confirmed that feeding by aphids with lower B. aphidicola titers reduced the production of attractants, while increased the emission of deterrents. As a result, M. persicae changed their feeding preference from infected to healthy plants. CONCLUSIONS We conclude that CMV infection reduces the B. aphidicola abundance in M. persicae. When viruliferous aphids feed on host plants, dynamic changes in obligate symbionts lead to a shift in plant volatiles from attraction to avoidance, thereby switching insect vector's feeding preference from infected to healthy plants.

Abstract
Feed efficiency is a highly important economic trait in sheep production and has a significant impact on the economic benefits of sheep farming. Microbial fermentation of the rumen has a vital role in the host's nutrition; the rumen microbiota might affect host feed efficiency. However, the relationship between the rumen microbiota and feed efficiency in sheep is unclear. In the present study, the microbiota of 195 Hu sheep was investigated and their residual feed intake (RFI), a commonly used measure of feed efficiency, was determined. From birth, all sheep were subjected to the same management practices. At slaughter, samples of liquid rumen contents were collected and subjected to amplicon sequencing for the 16S rDNA gene on the IonS5™XL platform. To identify the bacterial taxa differentially represented at the genus or higher taxonomy levels, we used linear discriminant analysis coupled with effect size and curve fitting. In the sheep rumen, the four most abundant phyla were Firmicutes, Bacteroidetes, Fibrobacteres, and Proteobacteria; and the dominant genera were unidentified Prevotellaceae, Fibrobacter, unidentified Lachnospiraceae, Saccharofermentans, and Succinivibrio. Pathway analysis of the 16S rDNA sequencing data from the rumen microbiota identified that carbohydrate metabolism was enriched. Using α-diversity analysis, we further identified that Observed species, ACE, Good's coverage, and Chao1 are more abundant (P < 0.01) in the low-RFI (L-RFI) group compared to the high-RFI (H-RFI) group. High-RFI sheep had a higher abundance of three bacterial taxa (Prevotellaceae, Negativicutes, and Selenomonadales), and one taxa was overrepresented in the L-RFI sheep (Succinivibrio), respectively. Furthermore, model fitting showed that Veillonellaceae, Sphaerochaeta, Negativibacillus, Saccharofermentans, and members of the Tenericutes, Kiritimatiellaeota, Deltaproteobacteria, and Campylobacterales were correlated with the sheep RFI classification and thus were indicative of a role in animal efficiency. Tax4Fun analysis revealed that metabolic pathways such as "energy metabolism," "metabolism of cofactors and vitamins," "poorly characterized," and "replication recombination and repair proteins" were enriched in the rumen from H-RFI sheep, and "genetic information processing" and "lipopolysaccharide biosynthesis" were overrepresented in L-RFI sheep rumen. In addition, six Kyoto Encyclopedia of Genes and Genomes orthology pathways were identified as different between H-RFI and L-RFI groups. In conclusion, the low RFI phenotype (efficient animals) consistently (or characteristically) exhibited a more abundant and diverse microbiome in sheep.

Abstract
Long noncoding RNAs (LncRNAs), as key regulators, have vital functions in various biological activities. However, in sheep, little has been reported concerning the genetic mechanism of LncRNA regulation of feed efficiency. In the present study, we explored the genome-wide expression of LncRNAs and transcripts of uncertain coding potential (TUCPs) in the livers of sheep with extreme residual feed intake (RFI) using RNA sequencing. We identified 1 523 TUCPs and 1 996 LncRNAs, among which 10 LncRNAs and 16 TUCPs were identified as being differentially expressed between the High-RFI and Low-RFI groups. Co-expression and co-localization methods were used to search for LncRNA and TUCP target genes, which identified 970/1 538 and 23/27 genes, respectively. Ontology and pathways analysis revealed that the LncRNAs/TUCPs that were highly expressed in the Low-RFI group are mostly concentrated in energy metabolism pathways. For example, LNC_000890 and TUCP_000582 might regulate liver tissue metabolic efficiency. The LncRNAs/TUCPs that were highly expressed in the High-RFI group are mostly enriched in immune function pathways. For example, TUCP_000832 might regulate animal health, thereby affecting feed efficiency. Subsequently, a co-expression network was established by applying the expression information of both the differentially expressed LncRNAs and TUCPs and their target mRNAs. The network indicated that differentially expressed genes targeted by the upregulated LncRNAs and TUCPs were mainly related to energy metabolism, while those genes targeted by the downregulated LncRNAs and TUCPs were mainly related to immune response. These results provide the basis for further study of LncRNA/TUCP-mediated regulation of feed efficiency.

Abstract
Tomato spotted wilt orthotospovirus (TSWV) causes serious crop losses worldwide and is transmitted by Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae). NSs protein is the silencing suppressor of TSWV and plays an important role in virus infection, cycling, and transmission process. In this research, we investigated the influences of NSs protein on the interaction of TSWV, plants, and F. occidentalis with the transgenic Arabidopsis thaliana. Compared with the wild-type Col-0 plant, F. occidentalis showed an increased number and induced feeding behavior on transgenic Arabidopsis thaliana expressing exogenous NSs. Further analysis showed that NSs reduced the expression of terpenoids synthesis-related genes and the content of monoterpene volatiles in Arabidopsis. These monoterpene volatiles played a repellent role in respect to F. occidentalis. In addition, the expression level of plant immune-related genes and the content of the plant resistance hormone jasmonic acid (JA) in transgenic Arabidopsis were reduced. The silencing suppressor of TSWV NSs alters the emission of plant volatiles and reduces the JA-regulated plant defenses, resulting in enhanced attractiveness of plants to F. occidentalis and may increase the transmission probability of TSWV.

Abstract
It is well documented that the canonical function of NIa-protease (NIa-Pro) of the potyviruses is responsible for cleaving the viral polyprotein into functional proteins. Although NIa-Pro is vital for the infection cycle of potyviruses, the function of NIa-Pro in the interaction of the potyvirus host is not clear. In this study, NIa-Pro is ectopically expressed from a potato virus X (PVX) vector and infiltrates Nicotiana benthamiana wild type and 16-TGS. The pathogenicity and inhibition of host transcriptional gene silencing (TGS) are characterized. Ectopic expression of NIa-Pro from a PVX vector resulted in severe mosaic symptoms followed by a hypersensitive-like response in N. benthamiana. Furthermore, PepMoV NIa-Pro was able to reverse established TGS of a green fluorescent protein transgene by reducing methylation of promoter sequences in N. benthamiana and possessed the capacity to interfere with the global methylation of N. benthamiana. Taken together, the results of this study likely suggest that PepMoV NIa-Pro is a pathogenicity determinant and a potent suppressor of host TGS and suggest that NIa-Pro may employ novel mechanisms to suppress host antiviral defenses. To the best of our knowledge, this is the first report of a plant RNA virus modulating host TGS in a novel manner by interfering with the establishment of the methylation step of the plant DNA methylation pathway.

Methods: A total of 7 560 permanent residents aged 50 years and over in seven regions of Gansu Province (altitude, 900 meters to 3 500 meters) were selected as subjects, including 2 402 males and 5 158 females, with an average age of 62.04 years. The cluster random sampling method was used to conduct the survey at village or township health service centers. The investigation procedure included questionnaire survey, pre-investigation, visual acuity examination, intraocular pressure measurement, slit lamp microscopy and fundus examination. The diagnostic criterion for cataract was typical opacity of the lens or no other eye diseases that led to visual impairment but with visual acuity less than 0.7. The prevalence of cataract was calculated according to factors such as altitude, age and sex. The Chi-square test and two-element unconditional logistic regression were used for statistical analyses. Results: A total of 7 560 people were surveyed. The prevalence rate of cataract was 39.7%, and the age-standardized prevalence was 37.7%. The prevalence of cataract increased with age (χ(2)=2 107.19, P<0.01). It was 14.1% in the group of 50-59 years, 42.9% in the group of 60-69 years and 79.2% in the group of over 70 years. The prevalence of cataract also increased with altitude (χ(2)=33.66, P<0.01). It was 36.9% in the group of altitude less than 1 000 meters, 39.0% in the group of altitude between 1 000 meters and 1 999 meters, 45.9% in the group of altitude between 2 000 meters and 2 999 meters, and 51.5% in the group of altitude more than 3 000 meters. With age stratification, the prevalence of cataract at high altitude was higher than that at low altitude (χ(2)=26.74, 16.06, P<0.01). Multivariate regression analysis showed that the risk of cataract was higher in subjects at altitude of 2 000-2 999 meters than those below 1 000 meters (OR=1.42, 95%CI 1.11-1.82), and even higher in those at altitude of 3 000 meters (OR=1.76, 95%CI 1.01-3.06). Conclusions: High altitude and old age are important risk factors for cataract, and high altitude is an independent risk factor for cataract. It is necessary for local health institutions to take measures to reduce the prevalence of blindness and low vision, especially the blindness caused by cataract.

Abstract
Objective: To compare the safety and efficacy between proximal gastrectomy and total gastrectomy and to ascertain the optimized procedure for patients with upper third gastric cancer through meta-analysis. Methods: The English literatures about proximal gastrectomy and total gastrectomy for upper third gastric cancer were searched from PubMed, EMBASE, the Cochrane Library and the Web of Science database and then collected. The quality of enrolled studies was independently assessed by two researchers according to the Newcastle-Ottawa Scale for retrospective studies and Jadad scale for RCT studies. The basic information of the literature and related clinical indicators were extracted. The primary endpoints were 5-year overall survival rate and recurrence rate. The secondary endpoints were operative time, intraoperative blood loss, morbidity of postoperative complication, incidence of anastomotic stenosis and incidence of reflux esophagitis. Considering the influence of tumor staging on postoperative clinicopathological features and prognosis, a subgroup analysis was performed on the literatures including cases of early gastric cancer and those including cases of tumor stage I to IV. Statistical analyses were carried out by the "metafor" and "meta" software packages from RevMan 5.3 software and R software (V3.2.4). Results: Twenty-five literatures involving 3667 patients (proximal gastrectomy for 1483, total gastrectomy for 2184) were finally enrolled for analysis, including 24 retrospective studies with ≥ 5 points and 1 RCT with 3 points, and all the literatures were of high quality. A total of 2516 cases of early gastric cancer were enrolled in 18 articles, including 1027 with proximal gastrectomy and 1489 with total gastrectomy. A total of 1151 cases with stage I to IV were enrolled in 7 articles, including 456 in proximal gastrectomy group and 695 in total gastrectomy group. Five-year survival rate was not significantly different for patients with early gastric cancer between the proximal gastrectomy group and total gastrectomy group (OR=1.16, 95% CI: 0.72 to 1.86, P=0.54). Similarly, there was no significant difference for patients with stage I to IV between the proximal gastrectomy group and the total gastrectomy group (OR=1.19, 95% CI: 0.92 to 1.53, P=0.18). Recurrence rate of early gastric cancer patients was not significantly different between the proximal gastrectomy group and the total gastrectomy group (OR=0.40, 95% CI: 0.05 to 3.16, P=0.39).However, the recurrence rate of the proximal gastrectomy group was higher than that of the total gastrectomy group in patients with stage I to IV (OR=1.55, 95% CI: 1.09 to 2.19, P<0.01), whose difference was statistically significant. There was no significant differences in postoperative complication between the groups, both in patients with early gastric cancer, and in those with stage I to IV (both P>0.05). The incidences of postoperative anastomotic stenosis (OR=3.57, 95% CI: 1.82 to 6.99, P<0.01) and reflux esophagitis (OR=2.83, 95% CI: 1.23 to 6.54, P=0.01) in the proximal gastrectomy group were significantly higher than those in the total gastrectomy group in patients with early gastric cancer. Conclusions: There is no significant difference in long-term survival outcomes between total gastrectomy and proximal gastrectomy for upper gastric tumors. However,incidence of anastomotic stenosis and reflux esophagitis, and tumor recurrence rate after total gastrectomy are significantly lower. The total gastrectomy is recommended as the first choice for advanced upper gastric tumor.

Abstract
Objective: To investigate the effects of preoperative percutaneous transhepatic biliary drainage on surgical treatment of type Ⅲ and Ⅳ hilar cholangiocarcinoma. Methods: Clinical data of 72 patients with hilar cholangiocarcinoma of the Bismuth-Corlette type Ⅲ and Ⅳ treated at Department of General Surgery,First Affiliated Hospital of Bengbu Medical College from January 2010 to December 2017 were analyzed retrospectively.Patients were divided into two groups based on whether PTBD was performed:a drained group and an undrained group.In the drained group,there were 31 patients,20 males and 11 females,aged (59.9±9.7)years (range: 39-73 years).Among them,14 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 17 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).In the undrained group,there were 41 patients, 26 males and 15 females, aged (60.8±7.8)years(range: 45-75 years).Among them, 17 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 24 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).Percutaneous transhepatic biliary drainage(PTBD)was used in the drained group.Under the guidance of ultrasound,one or more hepatobiliary ducts could be sufficiently drained,which had good effect and was not restricted by the obstruction location of hilar cholangiocarcinoma.The analysis of the measurement data was performed using t test,and the analysis of the count data was performed using χ(2) test,and the survival curve was plotted using Kaplan-meier method. Results: In total, 72 jaundiced patients with hilar cholangiocarcinoma underwent surgical treatment: 31 had PTBD prior to operation while 41 did not had PTBD.There were significant differences in ALT((93.2±21.4)U/L vs.(207.4±65.1)U/L),AST((87.6±18.1)U/L vs.(188.9±56.6)U/L)and total bilirubin((68.8±12.6)μmol/L vs.(227.5±87.7)μmol/L)between the patients after treatment and those before treatment(t=10.958, P=0.000; t=10.845, P=0.000; t=10.386, P=0.000).Compared with those in the undrained group, the operation time was shorter, the amount of intraoperative bleeding and the incidence of complications were lower in the drained group(t=-2.840, P=0.006; t=-3.698, P=0.000; χ(2)=4.108, P=0.043).There were no perioperative death cases in drained group and 2 perioperative death cases in undrained group.There was no significant difference in R0 resection rate between the two groups(χ(2)=0.778,P=0.378).The 1-,3-,5-year survival rate of patients in the drained group and the undrained group was 72.7%,34.2%, 13.7% and 72.8%, 31.5%, 11.8%, respectively.The difference was not statistically significant(all P>0.05). Conclusions: The preoperative percutaneous transhepatic biliary drainage in patients with hilar cholangiocarcinoma of Bismuth-Corlette type Ⅲ and Ⅳ could effectively shorten operative time, reduce amount of intraoperative bleeding and incidence of postoperative complications,but have no significant effect on the R0 resection rate and survival rate.

Abstract
Objective: To evaluate the clinical effects of ultrasound-guided subacromial injection of two drugs in treatment of subacromial impingement syndrome. Methods: This was a randomized controlled trial study, prospective collection of patients' data who were diagnosed as subacromial impingement syndrome at Orthopedic of Tianjin Fifth Central Hospital from January 2015 to August 2017. To ensure the randomness of the study, patients were randomized into two groups using a random number table. Pain(visual analogue scale(VAS)) and shoulder function (University of California Shoulder Score System(UCLA) and shoulder abduction) were performed before and after each injection.For continuous endings with multiple points in time, firstly, the normality, the homogeneity of variance, and the sphericity test of Mauchly were performed. After the condition was satisfied, the variance analysis of the two-factor repeated measurement data was performed. Results: Fifty-two patients completed the injection within 5 minutes and 41 patients got the final follow-up. Twenty-two patients in the corticosteroid group, 14 males and 8 females, aged (44.7±9.5) years old(range: 35-68 years old). The lesion involved 13 cases of superior shoulder, more than 1 time injection in 4 cases. There were 19 patients in the NSAID group, 7 males and 12 females, aged (37.2±10.1) years old(range: 27-63 years old), 10 cases with lesions involving superior shoulders, and 1 case with more than one injection. (1)VAS score: compared with pre-injection(Corticosteroid group 5.0(4.0-6.0)and NSAIDS group 5.0(4.0-6.0)), both groups showed significant pain relief at 60 minutes(1.0(1.0-2.0)and 1.0(1.0-2.0)) and 6 weeks(1.5(1.0-2.0)and 1.0(1.0-2.0)) after injection(χ2=47.293, 41.173, 45.174, 40.113; P<0.01). (2)UCLA score: compared with pre-injection(30.2±2.5 and 30.5±3.0), UCLA scores improved significantly in both groups at the 6-week after injection(Corticosteroid group: MD=9.727, t=19.218, P<0.001; NSAID Group: MD=9.579, t=11.467, P<0.01). The UCLA score improvement between the two groups was no statistical difference(all P>0.05). (3)shoulder abduction degree: compared with pre-injection(92.7±9.4 and 93.2±11.6), the abduction degree was significantly improved in both groups at 60 minutes(131.8±9.6 and 127.4±16.6) and 6 weeks(115.9±9. 1 and 127.9±14.4) after the injection, but the improvement in each time point has no statistical correlation(MD=4.450, t=1.069, P=0.292). NSAID group had better improvement of shoulder abduction degree than corticosteroid group at the 6 weeks after the injection(MD=-11.986, t=-3.238, P=0.002). Conclusions: Ultrasound-guided subacromial injection can reduce pain in patients with subacromial impingement syndrome.The effect of injection of NSAID drugs is the same as corticosteroid drugs, it can avoid hormone-induced complications and reduce the repeat of the punctures.

Abstract
Objective: To explore the correlation between the severity of gastroesophageal reflux cough and degree of gastroesophageal reflux. Methods: A cross-sectional investigation was carried out. Data of 174 cases of chronic cough were collected in Children's Hospital of Fuzhou from March 2009 to December 2016. The esophageal 24 hours pH value dynamic monitoring was used to detect gastric acid reflux index. Cases with abnomal results were divided into mild, moderate and severe groups according to severity of reflux and that of day and night cough symptoms, respectively. They were also divided into infant (1-3 years old), preschool (4-6 years old), and school age (>7 years old) groups according to age. Comparative analysis between groups by chi-square test and rank sum test were performed. Correlation analysis was used to analyze the correlation between cough severity and gastroesophageal reflux index. Results: A total of 174 patients with chronic cough, including 115 males and 59 females, aged from 1 to 15 years with an average age of (8.5±2.3) years, and (1.6±0.8) years of disease duration were enrolled. Among them, 129 cases (74.1%) were positive for esophageal reflux test and 45 cases (25.9%) with no obvious pathological gastroesophageal reflux. Patients with positive esophageal reflux test were divided into severe (n=37, 28.7%), moderate (n=23, 17.8%), and mild (n=69, 53.5%). There was no significant difference in the distribution of gastroesophageal reflux in each age group. (The proportions of mild, moderate and severe reflux in infants were 45.0% (9/20), 25.0% (5/20), and 30.0% (6/20), respectively. The proportions of mild, moderate and severe reflux in preschool children were 53.3% (32/60), 16.7% (10/60), 30.0% (18/60), respectively. The proportions of mild, moderate and severe reflux in school age children were 57.1% (28/49), 16.3% (8/49), 26.5% (13/49), respectively χ(2)=1.204, P=0.877). There was no correlation between age group and gastroesophageal reflux (r=-0.065, P=0.489).The severity of nighttime cough was positively correlated with percentages of distal esophagus pH≤4 in time, recumbent pH≤4 in time, and DeMeester score<14.72 (r=0.689, 0.621, and 0.707 respectively, all P<0.05). There was no statistically significant correlation between the severity of nighttime cough symptoms and percentage of standing pH≤4 in time (r=0.113, P>0.05). There were no statistically significant correlation between the severity of daytime cough and all gastroesophageal reflux markers (all P>0.05). Conclusion: The severity of nocturnal symptoms of gastroesophageal reflux cough is related to the degree of gastroesophageal reflux, to which clinical pediatricians should pay attention.

Abstract
Objective: To investigate the effect of AKT1 deSUMOylation induced by Ubc9 silencing on the proliferation and metastasis of hepatocellular carcinoma (HCC) cells. Methods: The Ubc9 gene was silenced using RNA interference, and the expression levels of Ubc9, SUMO1 and AKT1 protein were detected by Western blot. Cell proliferation and cell cycle was analyzed by MTT and flow cytometry. Wound healing and transwell assays were used to detect the cell migration ability. Furthermore, the xenograft model was established, and tumor growth curves were drawn. The in situ apoptotic rates was measured using TUNEL Apoptosis Assay. The expression of proliferating cell nuclear antigen (PCNA), matrix metalloproteinase (MMP)-2 and MMP-9 were evaluated by immunohistochemical staining. Results: Knockdown of Ubc9 gene significantly decreased the protein expression levels of Ubc9, conjugated SUMO1, free SUMO1 and AKT1 in HCC cells (P<0.05 for all). In control, siR-neg and siR-Ubc9 groups, the cell proliferation indexes were 53.19%, 54.25% and 39.17%, respectively. Moreover, cell migration distance and migrating cells per low power field for all these three groups were (59.47±4.66) μm and 89.44±8.36, (56.56±5.37) μm and 93.84±8.79, as well as (34.57±6.61) μm and 41.67±5.39, respectively. In the xenograft model, the weights of subcutaneous tumors for these three groups were (3.78±0.69) g, (3.72±0.72) g and (2.09±0.61) g, respectively. The corresponding apoptotic cell rates were (7.79±2.21)%, (6.45±2.48)% and (33.59±5.44)%, respectively. The expression levels of PCNA, MMP-2 and MMP-9 protein were significantly decreased in siR-Ubc9 group (P<0.05). Conclusions: Ubc9 silencing in HCC cells induces AKT1 deSUMOylation, and then inhibits the proliferation and metastasis. These results provide a new therapeutic strategy for liver cancer in the future.

Abstract
We aim to investigate the role of microRNA-495 (miR-495) in the intestinal mucosal barrier by indirectly targeting signal transducer and activator of transcription 3 (STAT3) through the Janus kinase-signal transducer and activator of transcription (JAK)/STAT3 signaling pathway in a mouse model of ulcerative colitis (UC). BALB/c mice were selected for establishing mice model of UC, and intestinal tissues of normal and UC mice were collected. ELISA was conducted for detecting levels of TNF-α, IL-6, IFN-γ and IL-10. The levels of SOD, MPO, MDA and NO were tested in the intestinal tissues. Dual luciferase reporter gene assay was applied to determine whether miR-495 directly targets STAT3. Cells were cultured, transfected and assigned into: normal group, blank group, NC group, miR-495 mimic group, miR-495 inhibitor group, siRNA-STAT3 group and miR-495 inhibitor+siRNA-STAT3 group. MTT was used for testing cell proliferation, flow cytometry for cell cycle and apoptosis. Northern blotting and Western blotting were performed to detect miR-495 expression and expressions of STAT3, JAK and Claudin-1. Results show that the UC group had higher expression levels of TNF-α, IL-6, IFN-γ, MPO, MDA, NO, STAT3 and JAK and lower expression levels of IL-10, SOD, miR-495 and Claudin-1, compared to the normal group. Dual luciferase reporter gene assay confirmed that STAT3 was the target gene of miR-495. The miR-495 mimic and siRNA-STAT3 groups had higher expressions of Claudin-1, higher cell proliferation and increased amount of cells in S phase, but lower expressions of STAT3 and JAK, decreased amount of cells in G0/G1 phase and cell apoptotic rate compared with the blank, NC groups. We also found that the miR-495 inhibitor+siRNA-STAT3 group had reduced miR-495 expression. No significant differences were found in mRNA and protein expressions of STAT3, JAK and Claudin-1, cell proliferation, apoptosis and cycle amongst the miR-495 inhibitor+siRNA-STAT3 groups. Our study provides evidence that miR-495 improves the intestinal mucosal barrier function by targeting STAT3 through inhibiting the JAK/STAT3 signaling pathway in UC mice.

Abstract
The rarity of primary small cell carcinoma of the esophagus (PSCE) has limited the clinical feature and survival analysis with large sample size. Tissue chromogranin A (CgA) protein expression has been reported to be a useful biomarker for diagnosing PSCE. Interestingly, recent studies have indicated tissue CgA as a significant prognostic marker in multiple human cancers, but without PSCE. The present study, thus, was undertaken to characterize the clinicopathological changes and to evaluate the associations of tissue CgA expression with clinical response on Chinese PSCE patients. All the 125 PSCE patients were enrolled from our 500,000 esophageal and gastric cardia carcinoma databases (1973-2015), constructed by the cooperative team from more than 700 hospitals in China and established by Henan Key Laboratory for Esophageal Cancer Research in Henan, China. Immunostaining for CgA showed that CgA was mainly located in cytoplasm of tumor cells with a positive detection rate of 44.6%. The CgA positive expression rate in PSCE at lower segment of the esophagus (72.2%) was higher than that at middle segment (41.5%) (P = 0.001). However, CgA protein expression did not correlated with lymph node metastasis (P = 0.767), TNM staging (P = 0.740), tumor invasion (P = 0.253), gender (P = 0.262), and age (P = 0.250). Multivariate survival analysis showed that the patients with higher CgA protein expression had a superior long survival than those without CgA expression (P = 0.037). The clinicopathological analysis showed that PSCE occurred predominantly in male (M:F = 1.9:1) at the middle segment (68%) of the esophagus. Histologically, 89.6% were pure PSCE and 10.4% were mixed type with either squamous cell carcinoma (8%) or adenocarcinoma (2.4%). It was noteworthy that, with the in-depth invasion from T1 to T2 and T3, the positive lymph node metastasis rate increased dramatically from 38%, 56% to 74%, respectively. The survival rates of 1-, 2-, 3-, and 5-year were 64%, 35%, 18%, and 7%, respectively. The Kaplan-Meier survival analysis showed that the young patients (≤60 years) had longer survival than the elderly (P = 0.011). Interestingly, multivariate survival analysis revealed that the patients with mixed PSCE had a significantly better survival than those with pure PSCE (P = 0.015). Furthermore, the median survival time for the patients with and without lymph node metastasis was 1.16 and 2.03 years, respectively. But, the difference was not significant (P = 0.143). Univariate analysis did not show any survival influence by gender, tumor location, tumor invasion depth, and TNM staging. It was noteworthy that, of the 13 early PSCE patients (T1N0M0), only one patient had more than 5 year survival, the others died with less than one or two year (65%). The present study indicates that the PSCE is of badly worsen prognosis, even in the pathological early stage. Tissue CgA protein expression is a promising maker not only for diagnosis and also for prognosis. Further assessment is needed to establish specific PSCE pathological staging system and to clarify the mechanisms of CgA protein in PSCE progression and prognosis.

Abstract
The present study aimed to determine the effects of high mobility group box 1 protein (HMGB1) on myocardial ischemia reperfusion (I/R) injury in rats following acute myocardial ischemia and investigate the underlying molecular mechanisms of these effects. Male Wistar rats were randomly divided into the following groups (n=10/group): Sham operation; I/R; HMGB50 (50 ng/kg HMGB1 before I/R); HMGB100 (100 ng/kg HMGB1 before I/R); and HMGB200 (200 ng/kg HMGB1 before I/R). Serum cardiac troponin I (cTnI), interleukin (IL)-6 and tumor necrosis factor (TNF)-α levels were subsequently measured. Myocardial levels of malondialdehyde (MDA) and superoxide dismutase (SOD) were also determined. Myocardial infarction size (IS) was determined by 2,3,5-triphenyltetrazolium chloride staining. Myocardial expression of hypoxia inducible factor (HIF)-1α and phosphorylated p38 mitogen-activated protein kinase (P-p38 MAPK) protein was measured using western blotting. The results demonstrated that HMGB1 significantly decreased serum levels of cTnI, IL-6 and TNF-α and myocardial IS in I/R rats compared with the sham group (all P<0.05). HMGB1 also significantly decreased and increased myocardial levels of MDA and SOD, respectively (both P<0.05). HMGB1 significantly increased myocardial expression of HIF-1α and decreased expression of P-p38 MAPK following I/R (both P<0.05). These effects of HMGB1 occurred in a dose-dependent manner. The results of the current study indicate that the cardioprotective effects of intravenous HMGB1 are associated with increased myocardial expression of HIF-1α via inhibition of P-p38 MAPK expression, leading to inhibition of the P-p38 MAPK signaling pathway.

Abstract
Tylenchulus semipenetrans is an important and widespread plant-parasitic nematode of citrus worldwide and can cause citrus slow decline disease leading to significant reduction in tree growth and yield. Rapid and accurate detection of T. semipenetrans in soil is important for the disease forecasting and management. In this study, a loop-mediated isothermal amplification (LAMP) assay was developed to detect T. semipenetrans using DNA extracted from soil. A set of five primers was designed from the internal transcribed spacer region (ITS1) of rDNA, and was highly specific to T. semipenetrans. The LAMP reaction was performed at 63°C for 60 min. The LAMP product was visualized directly in one reaction tube by adding SYBR Green I. The detection limit of the LAMP assay was 10-2 J2/0.5 g of soil, which was 10 times more sensitive than conventional PCR (10-1 J2/0.5 g of soil). Examination of 24 field soil samples revealed that the LAMP assay was applicable to a range of soils infested naturally with T. semipenetrans, and the total assay time was less than 2.5 h. These results indicated that the developed LAMP assay is a simple, rapid, sensitive, specific and accurate technique for detection of T. semipenetrans in field soil, and contributes to the effective management of citrus slow decline disease.

Abstract
The use of biological pesticide can greatly reduce the soil pollution in the environment. Exploring the effect of biological pesticide on community diversity and distribution of pathogenic bacteria will provide theoretic basis for subsequent researches on biological pesticide micro-ecological control. In order to explore the microbial ecological mechanism of pepper phytophthora blight, this research compared the difference of microbial diversity between rhizosphere soil of infected and healthy plants, and the effects of Rhodopseudomonas palustris PSB06 on microbial diversities of plant rhizosphere soil were investigated using Illumina MiSeq sequencing technology. The results showed that there was less difference in the microbial diversity from the same soil between the seventh day and the fourteenth day. The microbial diversity of rhizosphere soil of healthy plants was higher than that of rhizosphere soil of infected plants. The soil sprayed with Rhodopseudomonas palustris PSB06 exhibited the highest diversity. Moreover, the abundance of Actinomycetes in the rhizosphere soil of healthy plants was higher than that of infected plants, and the highest abundance of Actinomycetes was observed in the soil sprayed with Rhodopseudomonas palustris PSB06. The microbial diversity between rhizosphere soil of infected and healthy plants was significantly different. Spraying Rhodopseudomonas palustris PSB06 could significantly alter the microbial community structure of the soil. It could also increase the diversity of microorganism and the abundance of Actinomycetes in the soil.

Abstract
OBJECTIVE To explore response element that maintains basic transcriptional activity of intestinal trefoil factor (ITF) promoter. METHODS Truncated and mutant 5' flanking sequences of ITF gene were cloned from ITF promoter sequences by PCR, and then they were inserted into the pGL3-basic vector to construct truncated and mutant luciferase vectors to conduct the following experiments. (1) Human embryonic kidney 293 (HEK293) cells were divided into pGL3-basic group, pGL3-300 group, pGL3-280 group, pGL3-260 group, pGL3-240 group, pGL3-220 group, and pGL3-200 group according to the random number table (the same grouping method below), with 3 wells in each group, and they were respectively transfected with 500 ng corresponding plasmids and 15 ng renilla luciferase reporter plasmids pRL-TK. After being cultured for 48 hours, the relative luciferase activity of cells was measured by single tube detection system. (2) Another batch of HEK293 cells were divided into pGL3-basic group, pGL3-300 group, mutant 1, 2, 3, and 4 groups, with 3 wells in each group, and they were respectively transfected with 500 ng pGL3-basic, pGL3-300, mutant 1, 2, 3, and 4 plasmids and 15 ng pRL-TK plasmids. After being cultured for 48 hours, the relative luciferase activity of cells was measured as in (1). (3) Another batch of HEK293 cells were divided into blank control group and 10, 50 μmol/L mithramycin groups, with 3 wells in each group. After being transfected with 500 ng pGL3-300 plasmids and 15 ng pRL-TK plasmids, cells in blank control group were not transfected with mithramycin, while cells in the latter two groups were respectively transfected with 10 and 50 μmol/L mithramycin. After being cultured for 24 hours, the relative luciferase activity of cells was measured as in (1). (4) Another batch of HEK293 cells were divided into blank control group and 0.1, 0.2, and 0.3 μg pcDNA3.1-Sp1 groups, with 3 wells in each group. After being transfected with 500 ng pGL3-300 plasmids and 15 ng pRL-TK plasmids, cells in blank control group were not transfected with pcDNA3.1-Sp1 plasmids, while cells in the latter three groups were respectively transfected with 0.1, 0.2, and 0.3 μg pcDNA3.1-Sp1 plasmids. After being cultured for 48 hours, the relative luciferase activity of cells was measured as in (1). Data were processed with one-way analysis of variance and LSD test. RESULTS (1) The relative luciferase activity of cells in pGL3-basic group, pGL3-300 group, pGL3-280 group, pGL3-260 group, pGL3-240 group, pGL3-220 group, and pGL3-200 group was 1.00, 7.99±0.51, 2.03±0.55, 2.50±0.40, 2.50±0.15, 1.72±0.19 and 2.10±0.21, respectively. The relative luciferase activity of cells in pGL3-280 group, pGL3-260 group, pGL3-240 group, pGL3-220 group, and pGL3-200 group was significantly lower than that in pGL3-300 group (with P values below 0.01). (2) The relative luciferase activity of cells in pGL3-basic group, pGL3-300 group, mutant 1, 2, 3, and 4 groups was 1.00, 7.99±0.51, 2.10±0.56, 7.03±1.05, 5.09±1.40 and 8.15±1.48, respectively. The relative luciferase activity of cells in mutant 1 group was significantly lower than that in pGL3-300 group (P<0.01). The relative luciferase activity of cells in pGL3-300 group, mutant 2, 3, and 4 groups was similar (with P values above 0.05). (3) The relative luciferase activity of cells in 10 and 50 μmol/L mithramycin groups was respectively 3.07±0.60 and 2.93±0.55, which was significantly lower than that in blank control group (8.05±0.83, with P values below 0.01). (4) The relative luciferase activity of cells in 0.1, 0.2, and 0.3 μg pcDNA3.1-Sp1 groups was respectively 12.74±1.12, 14.52±1.25, and 15.66±1.82, which was significantly higher than that in blank control group (8.13±0.71, with P values below 0.05). CONCLUSIONS One Sp1 binding site, locating in the region from -301 to -293 bp of ITF promoter, is the core element for regulating the basic transcriptional activity of ITF.

Abstract
This study investigated the frequency of aspiration pneumonia in conscious stroke patients fed by a family member and examined the effect of introducing training in swallowing techniques by nurses. A total of 96 consecutive patients presenting with dysphagia due to acute stroke were included in the study. Patients presenting between January 2000 and July 2003 ( n = 48) were fed orally by a family member given general nursing information (group A), whereas those presenting between August 2003 and March 2005 ( n = 48) were fed orally by an experienced nurse trained in specific swallowing techniques (group B). All patients were examined daily for the presence of aspiration pneumonia. The incidence of aspiration pneumonia was 33.3% in group A and 6.3% in group B ( P < 0.05). The incidence of aspiration pneumonia in dysphagic stroke patients who are orally fed is still high. Training in swallowing during oral feeding offers clear protection against pneumonia in conscious stroke patients.

Abstract
Target leaf spot is a sorghum leaf disease caused by Bipolaris sorghicola, a species of fungus with a global distribution. In this study, we investigated the process by which B. sorghicola invades cells of barley, onion, Arabidopsis thaliana species, and sorghum. The results showed that within 8 h of coming into contact with host cells, the hyphal ends of B. sorghicola expand and form a uniform infective penetration pegbolt-like structure; a primary infection mycelium can be formed inside host cells within 24 h after contact, which can infect closed cells after 48 h. A mycelium can grow within the gap between cells and form infective hyphae. The pathogen infection process was the same in different host cells. B. sorghicola can affect root cells through soil infection, indicating that it may also have characteristics of soil-borne pathogens.

Abstract
The viscera of 10 kinds of marine fishes were collected for fish oil extraction and detection of DHA and EPA, two most important polyunsaturated fatty acids. The fish oil extraction ratio for the evaluated fishes varied from 0.95% to 10.18% (wt%). Pseudosciaena crocea presented the highest fish oil yield, followed by Mustelus manazo, Hippoglossus and Sciaenopsocellatus. A gas chromatography method was then established for analysis of EPA/DHA. The EPA concentration (in methyl ester form) in the fish oil varied from 1.39 to 10.65(mg/g). Epinephelus awoara presented the highest EPA concentration (p<0.05), followed by Epinephelussp, Sciaenopsocellatus and Hippoglossus. The DHA concentration (in methyl ester form) in the fish oil varied from 0.58 to 37.02 (mg/g). Epinephelus awoara presented the highest DHA concentration (p<0.05), followed by Sciaenopsocellatus, Pseudosciaena crocea and Hippoglossus. No strict positive correlation between the EPA/DHA concentration and the sea depth where the fish live was observed. The fishes living in middle depth presented highest EPA/DHA concentration.

Abstract
The effects of intravenous high mobility group box 1 (HMGB1) on myocardial ischemia/reperfusion (I/R) injury remains to be elucidated. The purpose of the present study was to investigate the effects of intravenous HMGB1 on the expression of hypoxia inducible factor-1α (HIF-1α) in the myocardium of rats following acute myocardial ischemia, and to examine the effects of intravenous HMGB1 on myocardial I/R injury. Male Wistar rats were divided into the following groups: Sham operation group (n=10), a group exposed to ischemia for 30 min and reperfusion for 4 h (I/R group) as a control (n=10), an HMGB group, in which 100 ng/kg HMGB was administered intravenously 30 min prior to ischemia (n=10), an LY group, in whic LY294002, an inhibitor of phosphoinositide 3-kinase (PI3K), was administered intravenously (0.3 mg/kg) 40 min prior to ischemia (n=10), and the HMGB1+LY group, in which HMGB1 (100 ng/kg) and LY294002 (0.3 mg/kg) were administered intravenously 30 min and 40 min prior to ischemia, respectively (n=10). The serum levels of cardiac troponin I (cTnI) and tumor necrosis factor-α (TNF-α), and myocardial infarct size were measured. The expression levels of phosphorylated Akt and HIF-1α were investigated using western blot analyses. The results showed that pre-treatment with HMGB1 significantly decreased serum levels of cTnI, and TNF-α, and reduced myocardial infarct size following 4 h reperfusion (all P<0.05). HMGB1 also increased the expression levels of HIF-1α and p-Akt induced by I/R (P<0.05). LY294002 was found to eliminate the effects of intravenous HMGB1 on myocardial I/R injury (P<0.05). These results suggest that intravenous pre-treatment with HMGB1 may exert its cardioprotective effects via the upregulation of the myocardial expression of HIF-1α, which may be regulated by the PI3K/Akt signaling pathway, in rats following acute myocardial I/R.

Abstract
AIM To investigate the correlations of MMP-2 and TIMP-2 polymorphisms with the risk and prognosis of gastric cancer (GC). METHODS With an incorporation of 254 GC patients in the case group and 250 healthy subjects enrolled as the control group, this experiment was conducted. Denaturing high performance liquid chromatography method was adopted to detect all genotypes under partial denaturation, haloptype analysis was completed with the Shesis software. Serum MMP-2 and TIMP-2 levels were determined by the immunohistochemical semi-quantitative analysis. The follow-up examination was conducted after the patients had completed systemic therapy and discharged. RESULTS The distribution frequencies of MMP-2-735C/T locus genotypes between groups were compared (P > 0.05). However, the distributions of alleles and genotype frequencies of MMP-2-1306C/T, TIMP-2-303G/A and -418G/C all exhibited statistical difference (all P < 0.05). The gene polymorphism of MMP-2-1306C/T was statistically correlated with the expression of MMP-2 protein (P < 0.05); the same result was also found regarding TIMP-2-303G/A (P < 0.05). The haplotype analysis revealed that the CGC frequency of the case group was apparently higher than that of the control group (P < 0.05), the positive survival rate of CGC was apparently lower than the negative one. CONCLUSION MMP-2-1306C/T, TIMP-2-303G/A and -418G/C variants might be correlated with GC susceptibility. Serum MMP-2 and TIMP-2 protein levels might be associated with GC susceptibility; Additionally, CGC haplotype might be the risk factor of GC.
