Authors: Bozek Andrzej , Zając Magdalena , Krupka Magdalena 
Published: September 2020

Abstract
Background: Concomitant atopic dermatitis (AD) and psoriasis (PS) are not common. However, both diseases are still of interest because of their comprehensive and diverse mechanism. The aim of the study was to present the clinical and immunological profile of patients with concomitant AD and PS coexist in comparison to patients with one of these diseases.Methods: In this observational study, 38 children with concomitant AD and PS with a mean age of 6.5 ± 3.2 yrs. were compared with similar 41 patients with only AD (5.3± 5.1 yrs) and with 28 with PS (6.4± 4.3 yrs). All patients underwent the dermatological examination including SCORAD and PASI questionnaire. TNF-α, IFN-γ, Il-2, Il-4, Il-5, Il-6, Il-8, Il-12, I-17, Il-18, Il-22, Il-33, TARC/CCL17 were measured by the use ELISA method and according manufacturer (ThermoFischer Scientific, US).Results: Patients with concomitant AD and PS were frequently boys or with overweight and with a proportional area distribution of skin lesions. A positive family history of atopic disease was more frequently reported by children with concomitant AD and PS, and with AD vs. PS. Significant differences were observed in the concentration of Il-17 in patients with AD and PS compared with that in AD or PS patients as follows: 9.1±3.7 pg/ml vs. 4.8±2.9 pg/ml and 5.2±3.9 pg/ml (PD vs. AD, p = 0.01; PD vs. PS, p = 0.03).Conclusion: AD and PS might coexist as overlapping disease. The role of T-helper 17 may be more meaningful than it appeared.

Abstract
Background: Cyclocarya paliurus (C. paliurus) leaves contain multiple health benefical metabolites, and therefore are often used in functional foods and Chinese herbal medicines. However, breeding difficulties confines its utilization. Consequently, cell suspension culture was developed to produce the bioactive secondary metabolites of C. paliurus leaves, but the content was comparatively low. In the present paper, Aspergillus Niger Elicitor (ANE) was used to stimulate the synthesis of triterpenoids in the suspension cultured C. paliurus cells, and the signal molecules crosstalk involved in this elicitation was further studied to interpret the underlying mechanism. Results: Total triterpenoids accumulation of the cultured C. paliurus cells elicited by 200 µg/mL ANE was 9.17 times higher than that of the untreated cells. Nitric oxide (NO), hydrogen peroxide (H2O2) and jasmonic acid (JA) played important roles in the elicitation as signal molecules. Under the ANE stimulation, the concentrations of NO, H2O2 and JA all increased significantly, but presented different change profiles and peaked at different times. Based on series experiments of NO quenching by C-PTIO, H2O2 blocking by DMTU, and JA synthesis inhibition by IBU and NDGA, together with exogenous NO, H2O2 and JA addition experiments, it was deduced that ANE improved triterpenoids synthesis in the suspension cultured C. paliurus cells via a complex signal transduction network, in which three deduced and three hypothetical signal transduction pathways might be involved. JA was not only the junction of NO and H2O2 signal pathways, but also the critical point in the whole signal network. RNA-seq analysis showed that a total of 3 candidate JA synthesis pathway genes including 1 LOX and 2 OPR were found to be significantly up-regulated under the ANE stimulation, along with 5 down-regulated JAZs and 1 up-regulated JAR1 regulating to JA signal transduction.Conclusions: ANE can significantly increase the triterpenoids synthesis in the suspension cultured C. paliurus cells. RNA-seq analysis validated the pivotal role of JA in this ANE elicitation. Our results provided references for the further studies on triterpenoids synthesis in C. paliurus under ANE treatment.
Transcriptome Analysis of Grafted Potato Rootstock for Improvement of Scion Late-Blight Resistance
Authors: Li Yuexin , Zhao Degang 
Published: September 2020

Abstract
Late blight seriously threatens potato cultivation worldwide. Damage caused by the fungus, which is severe and widespread, can lead to drastic reductions in potato yield and even total loss. Although grafting technology has been widely used to improve crop resistance, the effects and associated molecular mechanisms of grafting on resistance to potato late blight are unclear. In this study, we therefore performed RNA transcriptome sequencing of the scion when potato late blight-resistant variety Qingshu 9 and susceptible variety Favorita were used as the rootstock and scion, respectively, and vice versa. Using the sequencing results, we analyzed the influence of the rootstock on scion resistance and related molecular mechanisms. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that plant–pathogen interactions, the plant MAPK signaling pathway, and genes on the SA pathway were significantly up-regulated in the scion when Qingshu 9 was used as the rootstock. When Favorita was used as the rootstock, β-ketoacyl-CoA synthase-related genes in the scion, Qingshu 9, were significantly down-regulated. Resistance to late blight on scion leaves were also tested in vitro, which results consistent with those obtained by sequencing. All the generated evidence indicates that the use of resistant and susceptible varieties as rootstocks can respectively increase and reduce resistance to late blight. Our sequencing results further elucidate the molecular mechanism underlying the post-grafting effects of rootstocks on late blight resistance and provide a theoretical basis for the transfer of resistance genes between scions and rootstocks after grafting.

Published: September 2020

Abstract
Background: The maternal mortality rate is 412 per 100,000 live births in Ethiopia which is the highest in the world. Skilled birth attendance during childbirth and immediate postpartum care can prevent 75% of maternal mortality but women are not willing to deliver in the health institutions due to ignorance of their sensitive issues by health professionals. Additionally, the care given in the health institution is not psychologically supportive of what they need. Therefore, this study aimed to assess the level of abusive maternal care and associated factors during childbirth in North Wollo Hospitals, Northeast Ethiopia.Methods: Institutional based cross-sectional study design was implemented in 2018 with a sample size of 394. Stratified systematic random sampling was applied to select the study participants. Data was collected by using a structured questionnaire adapted from the White Ribbon Alliance Declaration of women's right during childbirth. Data were entered by EPI- data version 3.1 and analysed by using SPSS version 23. Bivariate and multivariable logistic regression analyses were carried out. Model fitness was assured.Result: The level of abusive care among childbearing women was 47.1%. Women who attended their childbirth at general hospital (AOR =0.13, 95% CI: 0.06, 0.26), women who had no antenatal care (AOR =2.08, 95% CI: 1.27, 3.39) and women who had two birth attendants (AOR =0.56, 95% CI: 0.35, 0.92) were significant association with abusive maternal care.Conclusion: The level of abusive maternal care in health institutions is high as compared to national and international standards. Women who attend their childbirth at general hospitals, having antenatal care and the number of birth attendants were factors associated with abusive maternal care. The interventions better to focus on increasing pregnant women’s ANC follow up. The health institutions also better increase the number of professional skilled birth attendants to address women’s concerns during childbirth.

Abstract
BRCA1 germ-line mutations are a major cause of hereditary breast cancer and BRCA1-deficient breast cancer shares many characteristics as sporadic basal-like breast cancer (BLBC). Effective therapeutic targets for BRCA1-deficient BLBC remain lacking. By utilizing a BRCA1-deficient BLBC mouse model based on intraductal injection of Krt8-Cre adenovirus to inactivate Brca1 and Trp53 in luminal mammary epithelial cells, here we report that the Wnt receptor Frizzled 7 (FZD7) serves as a biomarker and therapeutic target in the resulting mammary tumor cells and is particularly enriched in cancer stem cells / tumor-initiating cells (CSCs/TICs). Inhibiting FZD7-mediated Wnt signaling using a nontoxic FZD-binding fragment of C. difficile toxin B (TcdBFBD) attenuates growth of BRCA1-deficient tumor organoids and xenografted tumors, without damaging Wnt-sensitive tissues such as bones in vivo. Finally, FZD1/2/7-positive cells are enriched in chemotherapy-resistant cells in both BLBC and luminal breast tumors treated with cisplatin, and TcdBFBD synergizes strongly with cisplatin in inhibiting both tumor types. These findings demonstrate the therapeutic value for targeting FZD1/2/7 in treating breast cancers and establish TcdBFBD as a potential therapeutic agent targeting TICs and chemotherapy-resistant cancer cells.

Abstract
The outbreak of coronavirus disease 2019 (COVID-19) has been causing a global health emergency. Although previous studies investigated COVID-19 at different omics levels, the molecular hallmarks of COVID-19, especially in those patients without comorbidities, have not been fully investigated. Here, we presented a trans-omics landscape for COVID-19 based on integrative analysis of genomic, transcriptomic, proteomic, metabolomic and lipidomic profiles from blood samples of 231 COVID-19 patients, ranging from asymptomatic to critically ill, importantly excluding those with any comorbidities. Notably, we found neutrophils heterogeneity existed between asymptomatic and critically ill patients. Expression discordance of inflammatory cytokines at mRNA and protein levels in asymptomatic patients could possibly be explained by post-transcriptional regulation by RNA binding proteins (RBPs) and microRNAs. Neutrophils over-activation, induced arginine depletion, and tryptophan metabolites accumulation contributed to T/NK cell dysfunction in critical patients. Anti-virus interferons were gradually suppressed along with disease severity. Overall, our study systematically revealed multi-omics characteristics of COVID-19, and the data we generated could hopefully help illuminate COVID-19 pathogenesis and provide valuable clues about potential therapeutic strategies for COVID-19.

Abstract
Doxorubicin is a widely used antineoplastic drug. However, its major side effect, cardiotoxicity, results from cardiomyocyte loss that causes left ventricle (LV) wall thinning, chronic LV dysfunction and heart failure. Here, we show that transient therapy with thyroid hormone (triiodothyronine, T3) and dual-specificity phosphatase-5 (DUSP5) siRNA results in cardiomyocyte proliferation. siRNA-directed depletion of DUSP5, a nuclear localized p-ERK1/2-specific phosphatase, sensitizes cardiomyocytes to the proliferative effects of T3 by potentiating p-ERK1/2 accumulation resulting from the activation of T3-mediated insulin-like growth factor-1 (IGF-1) signaling. In mice with chronic doxorubicin cardiotoxicity, this therapy regenerates the LV myocardium by cardiomyocyte proliferation, reverses LV dysfunction and prevents progressive chamber dilatation, providing a strategy for addressing a currently untreatable condition.

Published: September 2020

Abstract
Background

Garlic and its constituents exhibit activities on modifying rumen fermentation and improving growth performance. As a by-product of garlic processing, garlic skin contains similar bioactive components as garlic bulb. However, studies in ruminants using garlic skin are scarce. This study was conducted to investigate the effects of garlic skin supplementation on rumen fermentation characterizes, growth performance, ruminal microbes and metabolites in ruminants. Twelve Hu lambs were randomly assigned into one of two treatments: basal diet (CON) or basal diet supplemented with 80 g/kg DM of gallic skin (GAS). The experiment lasted for10 weeks, with the first 2 weeks for adaptation.
Results

The results revealed that the average daily gain and volatile fatty acid concentration were higher (P < 0.05) in lambs fed GAS than that in the control group. Garlic skin supplementation did not significantly (P > 0.10) affect the α-diversity indices. Increased (P < 0.05) abundances of Prevotella, Bulleidia, Howardella, Methanosphaera but a decreased (P < 0.05) abundance of Fretibacterium were observed in GAS-fed lambs. In addition, the garlic skin supplementation favorably regulated (P < 0.05) pyrimidine metabolism, purine metabolism, vitamin B6 and B1 metabolism. Moreover, high correlations were observed between fluctuant rumen microbiota and metabolites.
Conclusions

Supplementation of garlic skin improved the growth performance of sheep by modifying rumen fermentation through inducing shifts in the rumen microbiome and metabolome.

Abstract
Background2019 novel coronavirus (2019-nCoV) is officially named severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), and is a positive-sense, single-stranded RNA coronavirus. The virus is the pathogen of coronavirus disease 2019 (COVID-19) and is infectious through human-to-human transmission. The fact that 2019-nCoV is very close to SARS-CoV has been proved by several evidences, but there are significant differences between MERS-CoV and them. Therefore, in this work, we used MERS-CoV as a probe to find the homology proteins with conserved sequences among these three known human highly pathogenic coronaviruses.MethodsThe primary protein sequences of three viruses translated from the complete genome were downloaded from National Center for Biotechnology Information (NCBI). The sequence alignments of ORF1ab proteins of three viruses were done by using Clustal Omega. The assessments of the feasibility of homology modeling were performed by using SWISS-MODEL.ResultsHere, by using computational biology, we propose that four nonstructural proteins nsp12, nsp13, nsp14, and nsp16 exhibit considerable homology among SARS-CoV, MERS-CoV, and 2019-nCoV. Among them, nsp12 and nsp13 amino acid sequences are more conserved. Considering the crucial role of these two proteins in the process of virus invasion and pathological response, we first proposed these two proteins as priority targets to design new or screen existing broad-spectrum antiviral drugs. The high consistency of primary sequence indicates the great similarity of three-dimensional structure and similar targets are likely to be inhibited by the same inhibitor. The inhibitors designed for these targets are likely to have broad-spectrum antiviral effect.ConclusionVery recently, some clinical trial reports preliminarily proved that Favipiravir and Remdesivir are effective for COVID-19. These clinical data provide some proof and basis for our conjecture in some degree. It is believed that the effective broad-spectrum antiviral drugs are not only helpful for the current epidemic situation, but also more beneficial for the future unpredictable epidemic situation.

Published: September 2020

Abstract
Background: To test the meaning of serum CRP, ESR, Platelet Count and Mean Platelet Volume ratio (PC/MPV), plasma Fibrinogen and D-Dimer in periprosthetic joint infection diagnosis (PJI). Methods: Clinical data of 149 patients diagnosed with osteoarthritis (Group A), PJI (Group B) and aseptic loosening after joint arthroplasy (Group C) were retrospectively studied. General data and preoperative serum CRP, ESR, Platelet Count and Mean Platelet Volume ratio (PC/MPV), plasma Fibrinogen and D-Dimer levels were analyzed. The sensitivity and specificity of serum CRP, ESR, Platelet Count and Mean Platelet Volume ratio (PC/MPV), plasma Fibrinogen and D-Dimer in PJI diagnosis were compared.Results: Expression level of serum CRP, ESR, PC/MPV and plasma Fibrinogen in Group B are higher than Group A and C. Expression level of plasma D-Dimer in Group B are higher than Group A but similar with Group C. When PC/MPV>31.70, plasma Fibrinogen > 4.01 μg/mL and plasma D-Dimer > 1.17 mg/L were set as the threshold value for the diagnosis of PJI, the sensitivity of PC/MPV in PJI diagnosis is lower than ESR and Plasma Fibrinogen. Whereas, there are no statistically significant differences when compared specificity of serum CRP, ESR, PC/MPV, plasma Fibrinogen and D-Dimer in PJI diagnosis.Conclusion: PC/MPV and plasma D-Dimer should not be used as the first screen markers for PJI diagnosis, whereas, the plasma Fibrinogen can be used as a new auxiliary marker for PJI diagnosis.

Abstract
BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies. Its larger mass size is widely acknowledged to be associated with increased lymph node (LN) metastatic potential. However, the quantitative relationships between tumor size and LN metastasis or survival remain unclear. Thus, this study aims to quantitatively identify the objective relationship between tumor size and prevalence of LN metastases across primary tumor size spectrums.METHODS: 9,958 resected PDAC patients without distant metastasis were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. The prevalence of LN metastases, LN ratio (LNR) and N2/N1 ratio were assessed amongst different tumor sizes, and the relationships were depicted by matched curves. RESULTS: In the enrolled cohort, age, tumor site, grade, American Joint Committee on Cancer (AJCC) 8th node staging, tumor size, chemotherapy and radiotherapy were identified as significant independent predictors for overall survival (OS) and cancer-specific survival (CSS). For tumors within 1-40 mm in size, the prevalence of node positive disease is closely modelled using a logarithmic formula [0.249×ln (size) + 0.452] × 100%, and then fluctuated between 70.0% and 80.0% when beyond 40 mm. The mean LNR increased in a stepwise manner as tumor size increased from 1-5 mm (LNR=0.024) to 41-45 mm (LNR=0.177); then, beyond 45 mm, it plateaued near 0.170. N2/N1 ratio gradually increased along with tumor size from 1-5 mm (N2/N1=0.286) to 41-45 mm (N2/N1=1.016), and when tumor size reached to 41-45 mm or more, the ratio stabilized around 1.000. CONCLUSION: Regional LN involvement demonstrated a logarithmic growth with increasing tumor sizes in resectable PDAC patients. The probability of metastasis in each regional LN for resectable PDAC patients with tumors greater than 40 mm in size was near 17.0% and their overall prevalence of LN metastasis was 70%-80%. Among which, 50% of patients had an N2 stage.

Abstract
Background: Ge-gen-qin-lian Decoction (GD) has been extensively used for the treatment of diarrhea with intestinal dampness heat syndrome(IDHS) with a satisfying therapeutic effect. However, the active ingredients and mechanism of GD against diarrhea with IDHS have not been fully elucidated. The occurrence of diarrhea is closely related to the intestinal flora, and the compound of Traditional Chinese Medicine(TCM) can exert its curative effect by regulating the intestinal flora, and exploring the relationship between the two is conducive to the clarification of pharmacology. Results: Animal experiments indicted that the OTU number and Alpha diversity index in the intestinal mucosa flora of the treatment group(cttm) recovered and higher than that of the control group(ctcm). PCoA results showed that there were differences in the community structure between the Con and GD. At the species level, the abundance of Lactobacillus crispatus and Muribaculum intestinal in the model group(ctmm) decreased, and the Neisseria mucosa increased (p<0.05). After being treated with GD, Muribaculum intestinal increased, and Lactobacillus curlyus and Neisseria mucosa decreased (p<0.05). Combined with network pharmacology analysis, we screened out 146 active ingredients in GD corresponding to 252 component targets, and 328 disease targets in diarrhea to obtain 31 drug-disease common targets. The key targets involved TNF, IL-6, EFGR etc. KEGG pathway enrichment resulted in HIF-1 signaling pathway, VEGFA signaling pathway, Adipocytokine signaling pathway and so on (p<0.05). Conclusions: GD could restore the diversity and abundance of intestinal mucosa in diarrheal mice with IDHS, promote the abundance of Muribaculum intestinal, inhibit the abundance of Neisseria mucosa. Through the characteristic of multiple targets and multiple channels, the active ingredients of GD intervened from oxidative stress and inflammatory response to adjust the balance of intestinal mucosa flora, thereby playing the role of treating diarrhea.
