Abstract
Background:Primary Sjögren’s syndrome (pSS) is an autoimmune disease that featured as lymphoplasmacytic infiltration of the exocrine glands leading to sicca symptoms1. However, its underlying molecular mechanisms remain elusive.Objectives:This study aims to identify differentially expressed genes (DEGs) and pathways associated with the progression of pSS using bioinformatics analysis and explore its pathogenesis.Methods:The pSS-associated gene chip data set GSE66795 was obtained from the Gene Expression Omnibus (GEO) database, which included 131 cases of fully-phenotyped pSS patients’ whole blood samples and 29 cases of control samples. DEGs were screened Using R software. Online tool Metascape2 was used to make Gene Ontology (GO) and KEGG pathway enrichment. The PPI network was performed using String database. Hub genes were identified by Cytoscape.Results:A total of 108 DEGs were captured, including 101 up-regulated genes and 7 down-regulated genes. GO enrichment showed that these DEGs were primarily enriched in defense response to virus, response to interferon-gamma, regulation of innate immune response, response to interferon-beta, double-stranded RNA binding, response to interferon-alpha. KEGG pathway enrichment analysis showed these DEGs were principally enriched in Influenza A, RIG-I-like receptor signaling pathway, necroptosis, Staphylococcus aureus infection. Finally, 9 hub genes (STAT1, IRF7, OAS2, GBP1, OAS1, IFIT3, IFIH1, OAS3, DDX60) had highest degree value.Conclusion:The findings identified molecular mechanisms and the key hub genes that may involve in the occurrence and development of pSS.References:[1]Francois H, Mariette X.

Abstract
Background:Pulmonary arterial hypertension with systemic sclerosis (SSc-PAH) is the main cause of death in patients with SSc. Early diagnosis and timely treatment are very important to reduce the mortality of patients with SSc-PAH1. At present, there are not many sensitive markers for the diagnosis of SSc-PAH. Therefore, it is necessary to mine more sensitive markers as more accurate and practical predictors, which is of great significance for the diagnosis and treatment of SSc-PAH.Objectives:To discover the differentially expressed genes (DEGs) and activated signaling pathways in SSc-PAH.Methods:Fifty-five samples (27 SSc-PAH v.s 28 normal controls) in GSE33463 chip data obtained from Gene Expression Omnibus (GEO) were included in this study. DEGs in SSc-PAH patients were screened by R, key pathways and hub genes were discoved by Metascape2, STRING3 and Cytoscape.Results:Total 431 genes with large differences were identified, including 238 up-regulated genes and 193 down-regulated genes, after standardizing the data (|logFC| > 1; P < 0.05). GO analysis showed that the upregulated genes were mainly involved in defense response to virus, hemoglobin complex, platelet alpha granule membrane and cytokine binding. The downregulated genes were mainly characterized by positive regulation of cell death, regulation of MAPK cascade, regulation of DNA-binding transcription factor activity and transcription factor AP-1 complex. Several significant enriched pathways obtained in the KEGG pathway analysis were Influenza A, Hepatitis C, IL-17 signaling pathway, MAPK signaling pathway, Toll-like receptor signaling pathway. Finally, after the selected differential genes were introduced into STRING online software, the data information of protein interaction network was derived, and 12 core genes in the network were identified, they were CXCL8, PPBP, LPAR1, FPR2, GNG11, CXCL10, LPAR5, JUN, C3AR1, CCR2, CCR3, IRF2.Conclusion:The genes and signal pathways related to SSc-PAH discovered by bioinformatics methods could not only provided new molecular markers for its diagnosis and treatment, but also provided new ideas for its related biological research.References:[1]Zheng JN, Li Y, Yan YM, et al.

Using mixed silages of sweet sorghum and alfalfa in total mixed rations to improve growth performance, nutrient digestibility, carcass traits and meat quality of sheep. Animal 2021; 15:100246. [PMID: 34058596 DOI: 10.1016/j.animal.2021.100246] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 04/02/2021] [Accepted: 04/08/2021] [Indexed: 10/21/2022] Open
Abstract
Combining sweet sorghum (SS) with alfalfa for ensiling has the potential to make a high-quality silage with relatively a better nutrient balance. However, the existing data are insufficient about how changes in ratios of SS to alfalfa in different silage mixtures affect animal performance and meat quality. Therefore, the objective of this study was to determine the effect of feeding total mixed rations containing mixed silages of SS and alfalfa on growth performance, nutrient digestibility, carcass traits and meat quality of Karakul sheep. Five total mixed rations were formulated with different SS proportions at 100%, 80%, 60%, 40%, and 20% on a fresh weight basis. Thirty 4-month old male Karakul sheep with 25.5 ± 1.4 kg BW were randomly allocated into five treatment groups, each with six lambs for this experiment. The results indicated that the Karakul sheep consuming total mixed rations containing SS-Alfalfa (SS-AF) silage mixtures with a lower proportion of SS tended to increase nutrient digestibility, growth performance, carcass traits, and meat quality. Feeding diets with SS at 40% and 20% inclusion rate showed a significant linear increase in the apparent digestibility of DM, CP and NDF, as well as subcutaneous fat thickness and water holding capacity (P < 0.5). Moreover, reduction in SS inclusion rate in these diets caused significant (P < 0.05) linear and quadratic increases in DM intake, final BW, average daily gain, carcass weight, and the amino acid contents of meat (P < 0.05). Conversely, feeding diet with lower SS inclusion rate led to decrease in feed conversion ratio and shear force significantly (P < 0.05) for these sheep. It appears that 40% inclusion of SS was the optimal rate in making the SS-AF silage mixture for lambs to achieve a superior production performance and high-quality meat products in Karakul sheep. However, further research is needed to investigate the effect of feeding SS-AF silage mixtures alongside contrasting ingredients on rumen function, ruminal microorganisms and digestive enzyme activity of sheep and other ruminant animals.

Abstract
Abstract
Background
Antibiotic-guidelines protect patients by reducing the burden of antibiotic-resistant strains. Some also contain charts for safe dosage and monitoring. Adherence to guidelines promotes patient safety.
Method
Data was collected retrospectively. Electronic records of all in-patients in Neuro-rehab wards on 24/7/2020 were initially analysed. Patients who had not received antibiotics from 1/5/2020 to 24/7/2020 were excluded. Data was analysed using tally chart.
Results
23 patients received antibiotics. Antibiotics were prescribed 45 times over study period. Urinary Tract Infections (UTIs) accounted for 37.8% of cases. Chest infections and skin infections accounted for 22% and 15% respectively. Sepsis of unknown origin and Other-Causes each accounted for 8.9%. In 95% of prescriptions, an indication was documented. Also, 100% compliance was recorded in Allergy status review and documentation of course-length of antibiotics. However, only 53.4% met clinical criteria for antibiotics administration. Of the cases which did not meet the clinical criteria, only 52.3% had been discussed with microbiology department /senior clinician.
Conclusions
Neuro-rehabilitation patients present with complex conditions and are sometimes non-communicative. This makes it difficult to adhere to clinical criteria as some of these require symptoms from patients. Such cases must be discussed with microbiologist/senior clinician.

Abstract
PURPOSE The aim of this study was to evaluate the efficacy of liposome-paclitaxel and carboplatin combination chemoradiotherapy for patients with locally advanced esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS Seventy-nine consecutive patients treated with liposome-paclitaxel based concurrent chemoradiotherapy between January 2015 and December 2019 at Cancer hospital of the University of Chinese Academy of Sciences (Zhejiang cancer hospital) were enrolled in this study. The overall response, toxicities, progression-free survival and overall survival were analyzed with SPSS software. RESULTS A total of 302 cycles of weekly chemotherapy were delivered, with a median 4 courses. After concurrent chemoradiotherapy (CCRT), the efficacy was classified as CR in 4 cases (5.1%), PR in 22 cases (28.2%) and SD in 51 cases (65.4%). The median PFS and OS time were 18.2 months and 23.4 months. The 3-year PFS and OS rates were 45.1% and 43.6%, respectively. CONCLUSIONS Liposome-paclitaxel and carboplatin concurrent with radiotherapy is a safe and effective modality for locally advanced ESCC. Further clinical investigation are warranted to evaluate the efficacy of this regimen.

Abstract
UNLABELLED In this large perspective cohort among European children and adolescents, we observed that daytime napping was positively associated with bone stiffness, while short or long sleep duration combined with poor sleep quality was associated with less bone stiffness. Our findings are important for obtaining optimal bone stiffness in childhood. INTRODUCTION To examine the cross-sectional and longitudinal associations between sleep duration, sleep quality, and bone stiffness index (SI) in European children and adolescents. METHODS Four thousand eight hundred seventy-one children aged 2-11 years from the IDEFICS study and 861 children aged 6-15 years from the subsequent I.Family study were included. Sleep duration (i.e., nocturnal sleep and daytime napping) and sleep quality (i.e., irregularly bedtime routine, have difficulty falling asleep and trouble getting up in the morning) were reported by self-administrated questionnaires. Nocturnal sleep duration was converted into age-specific z-scores, and total sleep duration was classified into short, adequate, and long based on the National Sleep Recommendation. Calcaneal SI of both feet were measured using quantitative ultrasound. Linear mixed-effects models with country as a random effect were used, with adjustments for sex, age, pubertal status, family socioeconomic status, physical activity, screen time, body mass index, and daylight duration. RESULTS Nocturnal sleep duration z-scores were positively associated with SI percentiles among participants with adequate sleep duration at baseline. Moreover, the positive association between daytime napping and SI percentiles was more pronounced in participants with adequate sleep duration at baseline, while at 4-year follow-up was more pronounced in participants with short sleep duration. In addition, extreme sleep duration at baseline predicted lower SI percentiles after 4 years in participants with poor sleep quality. CONCLUSION The positive associations between nocturnal sleep, daytime napping and SI depended on total sleep duration. Long-term detrimental effect of extreme sleep duration on SI only existed in individuals with poor sleep quality.

Abstract
Objective: To investigate the clinical effect of staged repair strategy for chronic sacrococcygeal radiation ulcer. Methods: The retrospective cohort study method was applied. Twelve patients with chronic sacrococcygeal radiation ulcer were admitted to Beijing Jishuitan Hospital from January 2010 to June 2020, including 7 males and 5 females, aged 38-74 years. The thorough debridement was performed in the first stage, with wounds area after debridement ranging from 8 cm×6 cm to 22 cm×14 cm, and continuous vacuum sealing drainage (VSD) was performed after the debridement operation. In the second stage, personalized surgery scheme was formulated according to the patient's age, systemic condition, vascular condition, and the position, size, and depth of wound. Six cases were reconstructed with superior/inferior gluteal artery perforator flaps, 4 cases were repaired with gluteus maximus myocutaneous flaps, 1 case was repaired with pedicled latissimus dorsi myocutaneous flap, and 1 case was reconstructed with free transplantation of latissimus dorsi myocutaneous flap. The area of flaps or myocutaneous flaps ranged from 10 cm×8 cm to 25 cm×18 cm. Donor sites of the flaps were sutured primarily in 9 patients and in the other 3 patients were repaired with intermediate split-thickness skin graft in back. The survival of flap or myocutaneous flap after operation, recurrence of tumor, and the appearance and texture of flap or myocutaneous flap, and wound healing were observed during follow-up. Results: Flaps or myocutaneous flaps in 11 patients survived after operation, and superior gluteal artery perforator flap in 1 patient had partial distal necrosis, which was covered again with flap pushed to the distal after debridement and resection of the necrotic tissue. The wounds in 8 patients achieved primary healing, 1 patient repaired with superior gluteal artery perforator flap experienced subcutaneous infection, 1 patient repaired with superior gluteal artery perforator flap suffered distal venous congestion of the flap, and 1 patient repaired with gluteus maximus myocutaneous flap had hematoma under myocutaneous flap, and 1 patient repaired with retrograde latissimus dorsi myocutaneous flap had incision exudation and dehiscence, which were all healed after dressing change, etc. There was no recurrence of tumor after the operation. The wounds healed well during follow-up of 2-52 months after discharge, with no recurrence of infection, and the flaps were soft in texture, with satisfactory appearance and well healed donor sites. Conclusions: On the basis of thorough debridement and VSD in the first stage, superior/inferior gluteal artery perforator flap, gluteus maximus myocutaneous flap, or pedicled/free latissimus dorsi myocutaneous flap with abundant blood supply is applied to repair chronic sacrococcygeal radiation ulcer in the second stage. The staged operation is reliable, with minimal injury to the donor site of flap and satisfactory therapeutic effect.

Abstract
OBJECTIVE To determine expression characteristics of XTP8 and TGIF1 in gastric carcinoma (GC), and the potential roles of XTP8/TGIF1 axis in influencing the progression of GC. MATERIALS AND METHODS The expression levels of XTP8 and TGIF1 in GC tissues and cells were detected. Their functions in prognosis in GC patients were evaluated by the Kaplan-Meier method. The correlation between the XTP8 level and the pathological indexes of the GC patients were analyzed. The changes in the proliferation, migration, and invasion capacities of MKN-45 and SGC-7901 cells affected by XTP8 and TGIF1 were assessed. The interaction between XTP8 and TGIF1 was determined through Dual-Luciferase reporter gene assay and rescue experiments. RESULTS XTP8 was upregulated in GC tissues and cells. XTP8 level was positively correlated with lymphatic and distant metastasis, as well as poor prognosis of GC patients. The silence of XTP8 attenuated proliferation, migration, and invasion capacities of MKN-45 and SGC-7901 cells. TGIF1 was the downstream gene binding to XTP8, which was downregulated in GC, and XTP8 negatively regulated the TGIF1 level in GC tissues. Importantly, the knockdown of TGIF1 could abolish the regulatory effect of XTP8 on GC cell behaviors. CONCLUSIONS XTP8 is upregulated in GC and is closely linked to lymphatic metastasis, distant metastasis, and poor prognosis of GC patients. Besides, it accelerates the malignant progression via negatively regulating TGIF1.

Abstract
Inducer of CBF expression 1 (ICE1), a MYC-like bHLH transcriptional activator, plays an important role in plants under cold stress. The ubiquitination-proteasome pathway mediated by high expression of osmotically responsive gene1 (HOS1) can effectively induce the degradation of ICE1 and decrease the expression of CBFs and their downstream genes under cold stress response in Arabidopsis, but knowledge of ubiquitination regulation of ICE1 by HOS1 is still limited in woody plants. In this study, a E3 ubiquitin ligase gene EcaHOS1 were amplified from Eucalyptus camaldulensis and the protein interactions between EcaICE1 and EcaHOS1 were analysed. Yeast two-hybrid (Y2H) and bimolecular fluorescence complementation (BiFC) assay results showed that EcaICE1 can interact with the EcaHOS1 protein in the nucleus and, further, the Y2H assay demonstrated that the 126-185 amino acid region at the N-terminus of the EcaICE1 protein was indispensable for its interaction with EcaHOS1 protein. Moreover, we found that the amino acids at positions 145, 158 and 184 within the key interaction region were the putative phosphorylation sites of EcaICE1, based on bioinformatics analysis, and only the substitution of serine (Ser) 158 by alanine (Ala) blocked the protein-protein interactions between EcaICE1 and EcaHOS1 based on Y2H and β-galactosidase activity assays using site-directed mutagenesis. We identified Ser 158 of EcaICE1 as the key putative phosphorylation site for its interaction with the EcaHOS1 protein.

Abstract
Precise knowledge of the charge and rigidity dependence of the secondary cosmic ray fluxes and the secondary-to-primary flux ratios is essential in the understanding of cosmic ray propagation. We report the properties of heavy secondary cosmic ray fluorine F in the rigidity R range 2.15 GV to 2.9 TV based on 0.29 million events collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The fluorine spectrum deviates from a single power law above 200 GV. The heavier secondary-to-primary F/Si flux ratio rigidity dependence is distinctly different from the lighter B/O (or B/C) rigidity dependence. In particular, above 10 GV, the F/Si/B/O ratio can be described by a power law R^{δ} with δ=0.052±0.007. This shows that the propagation properties of heavy cosmic rays, from F to Si, are different from those of light cosmic rays, from He to O, and that the secondary cosmic rays have two classes.

Abstract
Objective: To examine treatment outcomes of breast phyllodes tumors and the prognosis factors of local recurrence. Methods: This retrospective cohort study included 276 patients who underwent surgical resection at Breast Center, Peking University People's Hospital from January 2011 to December 2019. Tumor subtype and histopathological features were determined from pathology reports, and the deadline of follow-up was September 30th, 2020. All 276 patients underwent open surgery, including 17 patients of mastectomy, and 259 patients of lumpectomy. The enrolled patients were all female, with age of (41.5±11.3) years (rang: 11 to 76 years), and tumor diameter of 35(28) mm (M(QR)). The Kaplan-Meier method and Log-rank test were used for survival analysis. The multivariate analysis was implemented using the Cox proportional hazard model. Results: According the pathologic test, there were 191 patients of benign phyllodes tumor, 67 patients of borderline tumor and 18 patients of malignant tumor. There were 249 patients with a follow-up of more than 6 months, and 14.1% (35/249) had local recurrence. The time-to-recurrence was (28.6±22.2) months (range: 2 to 96 months), (29.1±18.1) months (range: 2 to 80 months), (32.1±30.1) months (range: 5 to 96 months) and (12.0±6.9) months (range: 8 to 20 months) for benign, borderline and malignant phyllodes tumors. Tumor diameter (≥100 mm vs.<50 mm, HR=3.968, 95%CI: 1.550 to 10.158, P=0.004) and malignant heterologous element (yes vs. no, HR=26.933, 95%CI: 3.105 to 233.600, P=0.003) were prognosis factors of local recurrence. One death from malignant phyllodes occurred after distant metastasis. The 3-year disease-free survival rates of benign, borderline and malignant phyllodes tumor were 88.2%, 81.7% and 81.4% (P=0.300). Conclusion: Phyllodes tumors have a considerable local recurrence rate, which may be associated with tumor diameter and malignant heterologous element.

Abstract
We report the observation of new properties of primary iron (Fe) cosmic rays in the rigidity range 2.65 GV to 3.0 TV with 0.62×10^{6} iron nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. Above 80.5 GV the rigidity dependence of the cosmic ray Fe flux is identical to the rigidity dependence of the primary cosmic ray He, C, and O fluxes, with the Fe/O flux ratio being constant at 0.155±0.006. This shows that unexpectedly Fe and He, C, and O belong to the same class of primary cosmic rays which is different from the primary cosmic rays Ne, Mg, and Si class.

Cullen BR, Weng HM, Talukder S, Cheng L. Cow milking order and its influence on milk production in a pasture-based automatic milking system. ANIMAL PRODUCTION SCIENCE 2021.

Abstract
Context
While several studies have documented the consistency of milking order and its association with milk yield in herds with conventional milking systems, there is limited data available on herds in the automatic milking systems (AMS) where cows move to the dairy voluntarily to be milked.
Aims
The present study was conducted to examine the consistency of milking order in AMS and its association with milk yield and cow characteristics.
Methods
The study was performed at The University of Melbourne Dookie Dairy in northern Victoria, Australia. The milking herd had up to 158 Holstein–Friesian cows in a pasture-based AMS with a three-way grazing system. The study utilised the individual-cow milking times, parity number, days in milk and data on daily production (milk yield in kilograms, fat and protein percentages and liveweight) from August 2017 till April 2018. Monthly milking order was determined for each milking session by ranking individual cows on the basis of their recorded time of milking.
Key results
A consistent milking order was observed with the order of cows at the beginning (percentile rank position 0–33) and end of the milking order (percentile rank position 68–100) being less variable than cows in the middle positions. Milking orders from any two consecutive months were highly correlated (P < 0.01). Energy-corrected milk yield was negatively associated with the milking position (5 of 9 months) and days in milk (8 of 9 months), but positively associated with parity number and liveweight (5 of 9 months). The cow factors such as energy-corrected milk yield, liveweight, parity and days in milk were poor predictors of milking order. This suggests that other factors such as health and social dominance might be of importance.
Conclusions
This observational study indicated that cows at the beginning of the milking order have a higher milk yield than do cows at the end of the milking order in pasture-based automatic milking systems.
Implications
Grazing-management strategies that allow cows at the end of the milking order to access fresh pasture are worthy of further investigation.

Abstract
Inflammation is a critical player in the development and progression of colon cancer. Basic leucine zipper transcription factor ATF-like 3 (BATF3) plays an important role in infection and tumor immunity through regulating the development of conventional type 1 dendritic cells (cDC1s). However, the function of BATF3 in colitis and colitis-associated colon cancer (CAC) remains unclear. Here, BATF3 wild-type and knockout mice were used to construct an AOM/DSS-induced CAC model. In addition, DSS-induced chronic colitis, bone marrow cross-transfusion (BMT), neutrophil knockout, and other animal models were used for in-depth research. We found that BATF3 deficiency in intestinal epithelial cells rather than in cDC1s inhibited CAC, which was depended on inflammatory stimulation. Mechanistically, BATF3 directly promoted transcription of CXCL5 by forming a heterodimer with JunD, and accelerated the recruitment of neutrophils through the CXCL5-CXCR2 axis, ultimately increasing the occurrence and development of CAC. Tissue microarray and TCGA data also indicated that high expression of BATF3 was positively correlated with poor prognosis of colorectal cancer and other inflammation-related tumors. In summary, our results demonstrate that intestinal epithelial-derived BATF3 relies on inflammatory stimulation to promote CAC, and BATF3 is expected to be a novel diagnostic indicator for colitis and CAC.

Abstract
Objective: To investigate the frequency and severity of systemic reactions (SRs) to standardized house dust mite subcutaneous immunotherapy (SCIT) in patients with perennial allergic rhinitis (AR), and to analyze the clinical risk factors. Methods: The clinical data of 362 patients including 209 males and 153 females, aged from 5 to 55 years old receiving SCIT at the Department of Otorhinolaryngology, the Third People's Hospital of Changzhou were collected from May 2014 to July 2017. The SRs were classified as early-onset and delayed-onset, and 4 grades (grade Ⅰ to Ⅳ) to assess severity. The records of SRs were retrospectively analyzed, including the numbers/frequencies, symptoms and signs, onset of reaction and treatment. And the relationships between SRs and patient's age, gender, allergen injection dose, accompanied allergic diseases were explored. All the statistical analyses were conducted using SPSS 19.0. Results: There were 57 cases (15.75%) of SRs in 362 patients. All the patients received a total of 12 308 injections and 111 SRs (0.90%) were observed. Among them, 31 (27.93%) were early-onset reactions and 80 (72.07%) were delayed-onset reactions; most of the SRs were grade Ⅰ reactions (n=83, 74.78%), followed by grade Ⅱ (n=25, 22.52%), grade Ⅲ (n=3, 2.70%), and no fatal reactions occurred. The incidence of SRs in patients>14 years old was higher than that in patients ≤14 years old according to the number of cases and injections (35.14% vs 13.54%, 2.34% vs 0.76%, χ(2) value was 11.679, 28.162, respectively, all P<0.05), but no significant differences of SRs were observed in gender (18.66% vs 11.76%, 5.98% vs 5.62%, χ(2) value was 3.166, 0.095, respectively, all P>0.05). Fifteen SRs (13.51%) occurred during the build-up phase and 96 (86.49%) during the maintenance phases. SRs could occur in lots of dose phases, and 95 (85.59%) were distributed at high concentrations more than 40 000 SQ-U. The incidence of SRs in patients with multiple allergic diseases was significantly higher than that in patients with AR alone, with asthma or atopic dermatitis (30.67% vs 11.85%, χ(2)=15.875, P<0.001). Meanwhile, the incidence of SRs in patients with pure AR was also significantly lower than that in patients with other allergic diseases (5.26% vs 20.56%, χ(2)=13.783, P<0.001). Conclusions: The incidence of SRs is less than 1% according to the injection times, the severity of SRs is mostly slight, and the safety and tolerance are good during standardized house dust mite SCIT in perennial AR patients. Delayed-onset SRs are more common. The incidence of SRs is significantly correlated with age, high dose of allergen vaccine injection, and concomitant other allergic diseases (asthma, atopic dermatitis, etc).

Abstract
OBJECTIVE This study aims to detect microRNA-326 expression in nasopharyngeal carcinoma (NPC) tissues and cell lines and to explore the potential mechanism of microRNA-326 inhibiting the proliferative capacity and invasiveness of NPC cells. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to examine microRNA-326 expression in 40 cases of NPC tissue samples and cell lines. Meanwhile, microRNA-326 mimics were transfected into NPC cells to up-regulate microRNA-326 level. Next, the influence of microRNA-326 mimics on the proliferation and invasiveness of NPC cells was observed by Cell Counting Kit-8 (CCK-8) assay and transwell assay, respectively. Bioinformatics analysis was applied to search for target genes which may have direct effects on microRNA-326. An EST1 luciferase reporter vector containing microRNA-326 binding site was constructed and the binding relation between ETS1 and microRNA-326 was detected by Dual-Luciferase reporting assay. Lastly, the underlying mechanism of microRNA-326 and ETS1 in NPC was further verified via cell reverse experiments. RESULTS Compared with control group, microRNA-326 expression was found remarkably decreased both in NPC tissue specimens and cell lines. The low expression of microRNA-326 could predict poor prognosis of patients with NPC. In vitro cell experiments revealed that overexpression of microRNA-326 remarkably inhibited the proliferative capacity and invasiveness of NPC cells. Bioinformatics analysis and Dual-Luciferase assay results suggested that microRNA-326 may bind to ETS1. Cell reverse assay indicated that inhibiting ETS1 expression partially reversed the changes in cell biological behavior induced by the down-regulation of microRNA-326 in CNE1 and 5-8F cell lines. CONCLUSIONS Overexpression of microRNA-326 in NPC cells could remarkably inhibit the proliferative capacity and invasiveness of NPC cells. In addition, microRNA-326 may participate in the development of NPC by inhibiting ETS1 expression.

Abstract
Leaf senescence is a complex and precise regulatory process that is correlated with numerous internal and environmental factors. Leaf senescence is tightly related to the redistribution of nutrients, which significantly affects productivity and quality, especially in crops. Evidence shows that the mediation of transcriptional regulation by WRKY transcription factors is vital for the fine-tuning of leaf senescence. However, the underlying mechanisms of the involvement of WRKY in leaf senescence are still unclear in wheat. Using RNA sequencing data, we isolated a novel WRKY transcription factor, TaWRKY40-D, which localizes in the nucleus and is basically induced by the progression of leaf senescence. TaWRKY40-D is a promoter of natural and dark-induced leaf senescence in transgenic Arabidopsis thaliana and wheat. We also demonstrated a positive response of TaWRKY40-D in wheat upon jasmonic acid (JA) and abscisic acid (ABA) treatment. Consistent with this, the detached leaves of TaWRKY40-D VIGS (virus-induced gene silencing) wheat plants showed a stay-green phenotype, while TaWRKY40-D overexpressing Arabidopsis plants showed premature leaf senescence after JA and ABA treatment. Moreover, our results revealed that TaWRKY40-D positively regulates leaf senescence, possibly by altering the biosynthesis and signalling of JA and ABA pathway genes. Together, our results suggest a new regulator of JA- and ABA-related leaf senescence, as well as a new candidate gene that can be used for molecular breeding in wheat.

Abstract
Objective: To evaluate the prognostic value of different critical care scoring systems in 28-day survival rate of patients with heat stroke. Methods: A retrospective analysis was conducted on the clinical data of 71 patients with heat stroke admitted to the department of emergency medicine of Beijing Luhe Hospital. Capital Medical University from July 2015 to September 2018. The general information and the worst values of vital signs and related pathophysiological indicators within 24 hours were collected and the sequential organ failure assessment (SOFA) , multiple organ dysfunction (MODS) , simplified acute physiological scoreⅡ (SAPS Ⅱ) and acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) were calculated. The patients were divided into the survival group (n=45) and the non-survival group (n=26) according to 28-day prognosis, and the clinical data and scores of the two groups were compared.The ROC curve was drawn to analyze the evaluation value of each scoring system on the survival rate of patients at 28-day. Kaplan-Meier method was used to plot the survival curve of patients. Results: There were no significant differences in age, sex, vital signs and laboratory parameters between two groups (P>0.05) . In non-survival patients, SOFA, SAPS Ⅱ, APACHE Ⅱ scores were significantly elevated in the survival group (P<0.05) . ROC curve analysis showed that the area under ROC curve (AUC) of SOFA score for predicting 28-day survival rate was the highest, which was significantly higher than the APACHE Ⅱ, SAPS Ⅱ, MODS score. When the best cut-off value of SOFA score was 9.0, the sensitivity was 84.6%, and the specificity was 71.1%. Kaplan-Meier survival analysis showed that 28-day survival rate after hospital discharge in patients with SOFA score<9 (n=27) was significantly higher than that in patients with SOFA score ≥9.0 (χ(2)=1.0, P<0.01) . Conclusion: SOFA, APACHE Ⅱ, SAPS Ⅱ on admission have been proved to have good prognostic ability to predict 28-day prognosis in heat stroke patients. Among them, SOFA score system has more accurate prediction value.

Abstract
Screening and therapeutic programs for colorectal cancer (CRC) are invasive or not effective and unable to meet patient needs. Major advances in immunogenomics may change this status but need more exploration. Differentially expressed genes and immune-related genes (IRGs) were identified by computational methods. A prognostic model was established and validated based on survival-related IRGs via stepwise multivariate Cox regression analysis. Nine IRGs were selected and identified as survival-related genes. A 7-gene prognostic model could offer a preliminary and valid determination of risk in CRC patients. The area under the curve of the receiver operating characteristic was 0.672. The 7-gene prognostic model might be used as a novel prognostic tool in CRC patients.

Abstract
Objective: To access the effectiveness and safety of the intrauterine balloon tamponade verse gauze packing combined with temporary abdominal aortic balloon occlusion in the management of placenta accreta spectrum (PAS). Methods: This was an open-label, randomized controlled trial conducted in Nanjing Drum Tower Hospital. The patients suspected with PAS for uterine preservation surgery under the multidisciplinary team care were recruited between Aug 2015 and Jan 2018. When bleeding could not be achieved after fetus delivered, and a temporary abdominal aortic balloon occlusion and the compression sutures as needed, the women were randomly allocated 1∶1 into balloon tamponade (n=81) or gauze packing (n=80) group. The primary outcome was successful bleeding arrests by avoiding second line surgeries. The secondary outcomes included the volume of blood loss during and after cesarean section, the rate of PPH, incidence and amount of blood transfusion, hysterectomy, postpartum pain, ICU admission, need for re-laparotomy, and the length of hospital stay, readmission, and interventional radiology complications. Results: All the women [100% (81/81)] in the balloon group were obtained hemostasis without further intervention, significantly higher than 88% (70/80) in the gauze group (P=0.001). Before uterine tamponade, blood loss were 820 ml (620-1 230) ml and 850 ml (605-1 442) ml, while placenta bed were sutured in 96%(78/81, 77/80) respectively (P>0.05).The proportion of blood loss≥1 000 ml was higher in the gauze group than that in the balloon group (P=0.006). Maternal adverse events involving total blood loss, puerperal morbidity and postpartum pain occurred more frequently in the gauze group (P<0.05). The following outcome showed no statistically significant difference between the two groups: the vascular occlusion time, the dose of radiation, and interventional radiology complication (P>0.05). The median volume infused into the lower and upper balloons is 70 ml (50-100 ml) and 180 ml (100-240 ml). Conclusions: Incrauterine balloon tamponade is as effective as gauze packing in hemostasis following the placenta delivery in PAS. Compared with gauze packing, the uterine balloon tamponade is more effective.

Abstract
We have witnessed successive stages since the Seventies in the advancements towards digital pathology. We agree with Dr Pallua et al on the tremendous changes that are taking place in pathology, all leading toward greater role of digitalization in the field of pathology, both in terms of consultation and teaching. In particular, distance teaching using digital pathology will grow into a mainstream mode of pathology teaching, something that has been reinforced by COVID-19.
