Abstract
Background: Strongyllodes variegatus (Fairmaire) is a major insect pest of oilseed rape in China. Despite its economic importance, the contribution of its population genetics in the development of suitable protection control strategy for oilseed rape crops is poorlys tudied. Using the sequences mitochondrial DNA cytochrome c oxidase subunit I (COI ) and cytochrome b (Cytb ) as genetic markers, we analyzed population genetic diversity and structure of 437 individuals collected from 15 S. variegates populations located in different oilseed rape production areas in China. In addition, we estimated the demographic history using neutrality test and mismatch distribution analysis. Results: The high level of genetic diversity was detected among the COI and Cytb sequences of S. variegates . The population structure analysis strongly suggested three distinct genetic and geographical regions in China with limited gene flow. The Mantel test showed that the genetic distance was greatly influenced by the geographical distance. The demographic analyses showed that S. variegates experienced population fluctuation during the Pleistocene Epoch, which was likely to be related to the climatic changes. Conclusion: Overall, these results demonstrate that the strong population genetic structure of S. variegates in China may is attributed to the isolation through the geographical distance among populations, their weak flight capacity and subsequently adaptation to the regional ecological conditions.

Abstract
Anterior uveitis (AU) is the most common form of uveitis. The differential diagnosis of AU is broad, ranging from infectious etiologies to autoimmune causes. However, approximately half remain idiopathic. Infections are the vision-threatening causes of AU which should be ruled out by history taking and detailed physical examination combined with guided work up. We report a rare case of bilateral granulomatous AU following hepatitis A virus (HAV) infection in an immunocompetent patient. A 35-year-old male presented to our center with a chief complaint of pain and redness in both eyes 3 days prior to the presentation. The patient’s medical and drug history was unremarkable. He had a history of river water consumption 20 days prior to presentation. The patient was diagnosed with acute bilateral granulomatous AU. All routine work up to investigate the etiology of the disease was unremarkable, except for the serology of acute HAV infection, which was positive. The patient was managed with the topical steroid and cycloplegic for two weeks with no recurrence at one-year follow up. Extra-hepatic complications of HAV were reported in previous studies including arthritis, urticaria, myocarditis, nephritis, and myositis. The mechanism of extra-hepatic complication of hepatitis A is unknown; however, immune-complex deposition is most likely the etiological cause. Our report represents a rare case of sudden onset with limited duration granulomatous AU as a presenting manifestation of HAV infection. Previous studies do not provide a direct evidence of granulomatous AU associated with the HAV infection.

Published: July 2020

Abstract
Background The highly pathogenic avian influenza (HPAI) H5N1 virus poses a potential threat to the poultry industry. The currently available avian influenza H5N1 vaccines for poultry are clade-specific. Therefore, an effective vaccine for preventing and controlling H5N1 viruses belonging to different clades needs to be developed.Results Recombinant L. lactis/pNZ8148-Spax-HA was generated, and the influenza virus haemagglutinin (HA) protein of A/chicken/Henan/12/2004 was displayed on the surface of Lactococcus lactis (L. lactis). Spax was used as an anchor protein. Chickens vaccinated orally with unadjuvanted L. lactis/pNZ8148-Spax-HA could produce significant humoral and mucosal responses and neutralizing activities against H5N1 viruses belonging to different clades. Importantly, unadjuvanted L. lactis/pNZ8148-Spax-HA conferred cross-clade protection against lethal challenge with different H5N1 viruses in the chicken model.Conclusion This study provides insights into the cross-clade protection conferred by unadjuvanted L. lactis/pNZ8148-Spax-HA, and the results might help the establishment of a promising platform for the development of a safe and effective H5N1 cross-clade vaccine for poultry.

Published: July 2020

Abstract
Background: While single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is a well-established noninvasive procedure for the evaluation of patients with coronary artery disease (CAD), it is unable to detect the presence of, or underestimates the extent of CAD in certain patients. We aimed to show that a bio-impedance device can detect early post-stress changes in several hemodynamic parameters, thereby serving as a potential marker for the presence of significant ischemia. Methods: Prospectively enrolled patients, referred to our Medical Center for clinically-indicated MPI, underwent testing using a Non-Invasive Cardiac System (NICaS) before and immediately after exercise. The differences between rest and stress hemodynamic parameters were compared with the severity and extent of myocardial ischemia by MPI. The study included 198 patients; mean age was 62 years, 26% were women, 54% had hypertension, and 29% diabetes mellitus. Of them, 188 patients had ≤10%, and 10 had >10% of myocardial ischemia. Results: In the first group, there was a significantly greater increase in post-exercise stroke index, stroke work index, cardiac index and cardiac power index (19.2%, 29.1%, 90.5% and 107%, respectively) compared with the second group (-2.7%, 3.8%, 43.7% and 53.5%, respectively), as well as a significantly greater decrease in total peripheral resistance index (-38.7% compared with -16.3%), with corresponding p values of 0.015, 0.017, 0.040, 0.016, and <0.001, respectively. Conclusions: Our data suggest that immediate post-stress changes in several hemodynamic parameters, detected by the NICaS, can be used as an important adjunct to SPECT MPI for the early detection of myocardial ischemia.

Abstract
Background: Hypovolemic shock and septic challenge are two major causes of acute kidney injury (AKI) in the clinic setting. Src homology 2 domain-containing phosphatase 2 (SHP2) is one of the major protein phosphatase tyrosine phosphatase (PTPs), which play a significant role in maintaining immunological homeostasis by regulating many facets of immune cell signaling. In this study, we explored whether SHP2 signaling contributed to development of AKI sequential hemorrhage (Hem) and cecal ligation and puncture (CLP) and whether inactivation of SHP2 through administration of its selective inhibitor, phenylhydrazonopyrazolone sulfonate 1 (PHPS1), attenuated this injury.Methods: Male C57BL/6 mice were subjected to Hem (a “priming” insult) followed by CLP or sham-Hem plus sham-CLP (S/S) as controls. Samples of blood and kidney were harvested at 24 h post CLP. The expression of neutrophil gelatinase-associated lipocalin (NGAL) , high mobility group box 1 ( HMGB1 ), caspase3 as well as SHP2:phospho-SHP2, extracellular-regulated kinase (Erk1/2) :phospho-Erk1/2, and signal transducer and activator of transcription 3 (STAT3):phospho-STAT3 protein in kidney tissues were detected by Western blotting. The levels of creatinine (Cre) and blood urea nitrogen (BUN) in serum were measured according to the manufacturer’s instructions. Blood inflammatory cytokine/chemokine levels were detected by ELISA.Results: We found that indices of kidney injury, including levels of BUN, Cre and NGAL as well as histopathologic changes, were significantly increased after Hem/CLP in comparison with that in the S/S group. Furthermore, Hem/CLP resulted in elevated serum levels of inflammatory cytokines/chemokines, and induced increased levels of HMGB1, SHP2:phospho-SHP2, Erk1/2:phospho-Erk1/2, and STAT3:phospho-STAT3 protein expression in the kidney. Treatment with PHPS1 markedly attenuated these Hem/CLP-induced changes.Conclusions: In conclusion, our data indicate that SHP2 inhibition attenuates AKI induced by our double-hit/sequential insult model of Hem/CLP and that this protective action may be attributable to its ability to mitigate activation of the Erk1/2 and STAT3 signaling pathway. We believethis is a potentially important finding with clinical implications warranting further investigation.

Abstract
Background : To explore the relationship between the pathological changes of colon, terminal ileum, lung, liver and kidney, and the changes of Bax, PCNA and PAF in a rat model of NEC. Methods: 140 neonatal sprague-dawley rats were randomly divided into 2 groups. NEC rat model is the experimental group. From the 1st day to the 7th day,10 rats were sampled in each group for pathological examination of colon, terminal ileum, lung, liver and kidney tissue. The levels of Bax, PCNA and PAF were investigated by immunohistochemistry. Results: On the 1st day, the colon, terminal ileum, lung, liver and kidney showed inflammatory damage. On the 5th day, inflammatory injury was decreased. The inflammatory injury was nearly gone by the 7th day. There were differences in the time of apoptosis in intestine. In the intestine, the proliferation of weak to strong. Bax in liver and kidney showed marked apoptosis and apoptosis time increased in lung. PCNA was elevated in lung, liver and kidney, and the expression of PAF in lung and liver was increased. Conclusions: NEC can lead to secondary injury of different degrees in colon, terminal ileum, lung, liver and kidney, and the degree and time of injury and repair were different. In general, organ repair played a leading role on the 4th day after modeling.

Abstract
Background: The implications of congenital Zika Virus (ZIKV) infections for pediatric neurodevelopment and behavior remain inadequately studied. The aim of this study is to investigate patterns of neurodevelopment and behavior in children with different levels of ZIKV-related microcephaly or with prenatal ZIKV exposure in the absence of microcephaly. Methods: We conducted a cross-sectional study, nested in a cohort, of 274 children (aged 10-45 months) who were born during the peak and decline of the microcephaly epidemic in Northeast Brazil. Participants were evaluated between February 2017 and August 2019 at two tertiary care hospitals in Recife, Brazil. We analyzed the children in four groups assigned based on clinical and laboratory criteria: Group 1 had severe microcephaly; Group 2 had moderate microcephaly; Group 3 had prenatal ZIKVxposure confirmed by maternal RT-PCR testing and no microcephaly; and Group 4 was a neurotypical control group. Groups were evaluated clinically for neurological abnormalities and compared using the Survey of Wellbeing of Young Children (SWYC), a neurodevelopment and behavior screening instrument, and a SWYC adapted form to compare severe cases. Results: Based on the SWYC screening, we observed differences between the groups for developmental milestones but not behavior. Among children with severe microcephaly of whom 98.2% presented with neurological abnormalities, 99.1% were at risk of development delay, and presented similar performance whether evaluated under or over 24 months of age. Among children with moderate microcephaly of whom 60% presented with neurological abnormalities, 65% were at risk of development delay. For children without microcephaly, the percentages found to be at risk of developmental delays were markedly lower and did not differ by prenatal ZIKV exposure status: Groups 3, 13.8%; Group 4, 21.7%. Conclusions: Among groups of children with prenatal ZIKV exposure, we found a gradient of risk of development delay. Children with severe microcephaly were at highest risk, while normocephalic ZIKV-exposed children had similar risks to unexposed control children. We propose that ZIKV-exposed children should undergo first-line screening for neurodevelopment and behavior using the SWYC. Early assessment and follow-up will enable at-risk children to be referred to a more comprehensive developmental evaluation and to multidisciplinary care management.

Abstract
Background Globally, 45% of under-five deaths are, directly or indirectly, attributable to malnutrition, most of these deaths are in low- and middle-income countries (LMICs). Children in the first 6 months of life are particularly vulnerable. An estimated 4.7 million infants under the age of 6 months are moderately wasted whereas 3.8 million are severely wasted. Despite an increased risk to a child of a malnourished woman, there are discrepancies in guidance in this area. Methods This is a community-based, open-label multi-arm factorial randomized controlled trial, using parallel assignment with 1:1:1 allocation ratio, in low-income squatter settlements of urban Karachi, Pakistan. In the control group (Control Arm A), women are randomized to standard counseling only; whereas in the first intervention group (Arm BIntervention arm 1), lactating women receive two sachets of balanced energy-protein (BEP) supplementation per day from enrollment till the infant reaches six months of age, in the second intervention group (Arm CIntervention arm 2), lactating women receive same BEP as in intervention Arm B while their babies also receive a single stat dose (20mg/kg orally) of azithromycin at 42 days. The primary outcome is relative length velocity from 0 to 6 months by the limb of allocation. The primary analysis will be Intention-to-treat analysis. Trial registration Registration of the trial is done at ClinicalTrials.gov. NCT03564652, registered on June 21, 2018.

Abstract
Background

Recently, it has been reported that miRNA is involved in pterygium, however the exact underlying mechanism in pterygium is unrevealed and require further investigation.

Methods

The differential expression of miRNA in pterygium was profiled using microarray and validated with quantitative real-time polymerase chain reaction(qRT-PCR). Human conjunctival epithelial cells (HCEs) were cultured and treated with transforming growth factor β (TGF-β) and epidermal growth factor (EGF) and transfected with miR-199a-3p/5p mimic and inhibitor. Markers of epithelial-mesenchymal transition (EMT) in HCEs were detected using western blot and immunohistochemistry. Cell migration ability was determined using wound healing and transwell assay, while apoptosis was determined by flow cytometry. The target genes of miR-199a were confirmed by the dual-luciferase reporter assay.

Results

TGF-β and EGF could induced EMT in HCEs and increase miR-199a-3p/5p but suppress target genes, DUSP5 and MAP3K11. With the occurrence of EMT, cell migration ability was enhanced, and apoptosis was impeded. Promoting miR-199a-3p/5p expression could induce EMT in HCEs without TGF-β and EGF, while suppressing miR-199a-3p/5p could inhibit EMT in TGF-β and EGF induced HCEs. In a word, TGF-β and EGF induced EMT could be regulated with miR-199a-3p/5p-DUSP5/MAP3K11 axes. The validated results in tissues showed that, compared with control conjunctival tissues, miR-199a-3p/5p were more overexpressed in pterygium, while DUSP5/MAP3K11 were lower expressed. In addition, bioinformatics analysis indicated the miR-199a-3p/5p-DUSP5/MAP3K11 was belong to MAPK signalling pathway.

Conclusions

TGF-β and EGF induce EMT of HCEs through miR-199a-3p/5p-DUSP5/MAP3K11 axes, which explains the pathogenesis of EMT in pterygium and may provide new targets for pterygium prevention and therapy.

Abstract
Background: This study was intended to investigate the genomic landscape of the immune microenvironments of brain metastases in breast cancer. Methods: Three gene expression profile datasets (GSE76714, GSE125989 and GSE43837) of breast cancer with brain metastases were downloaded from Gene Expression Omnibus (GEO) database. After differential expression analysis, the tumor immune microenvironment and immune cell infiltration were analyzed. Then immune-related genes were identified, followed by function analysis, transcription factor (TF)-miRNA-mRNA co-regulatory network analysis, and survival analysis of metastatic recurrence. Results: The present results showed that the tumor immune microenvironment in brain metastases was immunosuppressed compared with primary caner. Compared with primary cancer samples, the infiltration ratio of plasma cells in brain metastases samples was significantly higher, while the infiltration ratio of macrophages M2 cells in brain metastases samples was significantly lower. Total 42 immune-related genes were identified, such as THY1 and NEU2. CD1B, THY1 and DOCK2 were found to be implicated in the metastatic recurrence of breast cancer. Conclusions: Targeting macrophages or plasma cells may be new strategies for immunotherapy of breast cancer with brain metastases. THY1 and NEU2 may be potential therapeutic targets for breast cancer with brain metastases, and THY1, CD1B and DOCK2 may serve as potential prognostic markers for improvement of brain metastases survival.

Abstract
Background: To investigate the CT changes of different clinical types of COVID-19 pneumonia. Methods: This retrospective study included 50 patients with COVID-19 from 16 January 2020 to 25 February 2020. We analyzed the clinical characteristics, CT characteristics and the pneumonia involvement of the patients between the moderate group and the severe and critical group, and the dynamic changes of severity with the CT follow-up time. Results: There were differences in the CT severity score of the right lung in the initial CT, and total CT severity score in the initial and follow-up CT between the moderate group and the severe and critical group (all p <0.05). There was a quadratic relationship between total CT severity score and CT follow-up time in the severe and critical group (r2=0.137, p=0.008), the total CT severity score peaked at the second follow-up CT. There was no correlation between total CT severity score and CT follow-up time in the moderate group (p >0.05). There were no differences in the occurrence rate of CT characteristics in the initial CT between the two groups (all p >0.05). There were differences in the occurrence rate of ground-glass opacity and crazy-paving pattern in the second follow-up CT, and pleural thickening or adhesion in the third follow-up CT between the two groups (all p <0.05). Conclusions: The CT changes of COVID-19 pneumonia with different severity were different, and the extent of pneumonia involvement by CT can help to assess the severity of COVID-19 pneumonia rather than the initial CT characteristics.
