Abstract
Objective: To investigate the characteristics of morphological changes of inner retinal layer after internal limiting membrane peeling in macular hole surgery. Methods: Retrospective case study. Patients with idiopathic macular hole from 2015 to 2018 underwent vitrectomy+internal limiting membrane peeling (inverting)+ gas tamponade in China-Japan Friendship Hospital were investigated. A total of 19 eyes (17 patients) were enrolled, including 4 males (4 eyes) and 13 females (15 eyes). The average age was 62.74±5.25 years. Optical coherence tomography (OCT) was used to obtain the topographic maps of retinal thickness, the thickness of retinal ganglion cell complex and probability maps, and the Angio/en-face maps of macular retina. The characteristics of the morphological changes of the inner retinal were comprehensively analyzed. Results: Among 19 eyes, 9 eyes had internal limiting membrane peeling, 8 eyes had lotus-like internal limiting membrane inverting, and 2 eyes had the uper180 degrees internal limiting membrane inverting. The minimum diameter of macular hole was (543.06+220.17) μm and the maximum diameter was (947.18+319.12) μm. The follow-up time was (21.05+9.66) months, and the visual acuity was 0.45+0.35 at the last follow-up. In the 19 eyes, all the macular holes were closed postoperatively and dissociated optic nerve fiber layer appearance (DONFL) and concentric macular dark spots (CMDS) all showed, as well as mGCC thinning. The changes of CMDS and mGCC in 2 eyes in the uper180 degrees internal limiting membrane inverting group were mainly seen in the upper retina and in the remaining 17 eyes were seen diffused around the macula, which roughly corresponded to the extent of internal limiting membrane peeling. Two eyes showed clear decrease of retinal capillary density on Angio/map. Conclusions: Long-term morphological changes of the inner retinal after internal limiting membrane peeling in macular hole surgery are obvious. In addition to the appearance changes like DONFL and CMDS, the macular ganglion cell complex (mGCC) is also involved. (Chin J Ophthalmol, 2019, 55:747-756).

Abstract
Abstract
Background
Holt-Oram syndrome (HOS), characterized by upper limb malformations, congenital heart diseases (CHD) and/or cardiac conduction abnormalities, is an autosomal dominant disease. Almost all the HOS patients suffer from cardiac and limb abnormalities at the same time. Among them, atrial septal defect (ASD) is the most common cardiac anomaly. The unusual phenotype in a pedigree including multiple members with isolated ASD and a few with isolated limb deformity attracted attention.
Aim
To detect mutant genes of ASD in this pedigree and make a definitive diagnosis. To investigate the mutant type of the gene and illustrate the possible mechanism of heterogeneous phenotype.
Methods
Echocardiography, electrocardiography and physical examination were given to a four-generation Chinese HOS family. Of all 11 patients in this pedigree, eight patients had isolated ASD and one patient had isolated finger deformity. In addition, two patients suffered from both diseases (Figure. 1). Whole Exome Sequencing was performed on the proband and his relatives including three with ASD only, one with finger deformity only and one normal person. Sanger sequencing was performed on biological relatives in this pedigree to valid rare variants. Single nucleotide polymorphisms and insertions/deletions were identified using the GATK program. Pathogenicity was predicted in software like SIFT, Ployphen-2, MutationTaster and CADD_phred.
Results
An exon site mutation (c.100dupG:p.Ala34fs) of TBX5 was detected in all the patients of this pedigree. This mutation site is located in front of T-box and most probably leads to haploinsufficiency of TBX5 protein. In addition, only 42 variants (1 splicing single nucleotide variants (SNV), 15 insertions/deletions, 24 nonsynonymous SNVs, 1 stopgain SNVs and 1 unknown) were found in 29 genes, which are related to cardiac disease.
Figure 1
Conclusions
Our study revealed a mutation (c.100dupG:p.Ala34fs) of TBX5 and further demonstrated the possibility of HOS-related TBX5 mutation in patients with congenital ASD only. This study clarified the diagnosis of this pedigree, provided genetic counseling and promoted the prevention and treatment of HOS. Further research is needed on mechanisms that may lead to phenotypic variation between and within families, such as random monoallelic expression.

Abstract
AIM To investigate the collaborative networks among expert clinical nurse and midwifery researchers in eastern and southern Africa. METHODS Thirty-eight clinical nurse and midwifery researchers completed an online survey to analyse collaboration between respondents. Data were analysed using social network analysis, generating a network map and associated measurements. RESULTS Regional collaboration was poor. Those links that did exist centred on geographic proximity and participation in regional and international organizations. CONCLUSION These results help us to understand better ways to strengthen and support nursing and midwifery clinical research in eastern and southern Africa. IMPLICATIONS FOR NURSING POLICY Clinical nursing and midwifery research capacity building efforts should focus on supporting collaboration networks among individuals and institutions in the region.

Abstract
Long noncoding RNAs (lncRNAs) have been shown to play crucial roles in cancer metastasis, yet the lncRNAs landscape of lung adenocarcinoma has not been completely characterized. The aim of this study was to assess the expression profile and potential function of lncRNA in lung adenocarcinoma and in spinal metastasis (SM). A genome-wide microarray analysis was conducted on lung adenocarcinoma and SM tissue from ten Chinese patients. A total of 3,345 differentially expressed lncRNAs were detected. Of those, 761 lncRNAs were upregulated and 2,584 were downregulated (fold-change >2.0, p<0.05). These differentially expressed lncRNAs were not evenly distributed among the chromosomes of human genome. Volcano plots of these differentially expressed lncRNAs revealed large variability in lncRNAs expression among 12 patients, indicating that certain lncRNAs may play a positive role in SM of lung adenocarcinoma. Gene Ontology enrichment and pathway analysis identified several remarkably dysregulated biological pathways that affect cell adhesion and the interaction of cytokines and cytokine receptors. Co-expression network analysis showed that 9,458 lncRNAs had verified cis- and trans- target genes. All 2,317 cis targeted genes were confirmed to be differentially expressed and influenced by dysregulated lncRNAs in SM of lung adenocarcinoma. Top ten markedly dysregulated lncRNAs and mRNAs were verified from the co-expression network. In conclusion, this study was a genome-wide survey of dysregulated lncRNAs and corresponding mRNAs that comprise co-regulation networks for SM and lung adenocarcinoma tissues. These dysregulated lncRNAs and mRNA networks could be used as therapeutic gene targets to prevent SM of lung adenocarcinoma and to predictively evaluate treatment efficacy.

Abstract
OBJECTIVE The aim of this study was to explore the role of microRNA-233-3p (miR-233-3p) in the development of oral squamous cell carcinoma (OSCC), and to elucidate the underlying mechanism. PATIENTS AND METHODS The expression of miR-233-3p in OSCC tissues and cell lines was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The target of miR-233-3p was detected and evaluated by L-test and Western blot assays, respectively. Furthermore, the effects of miR-233-3p on cell proliferation, migration and apoptosis were discussed by cell counting kit-8 (CCK-8), scratch-wound and flow cytometry test. RESULTS MiR-233-3p was lowly expressed in OSCC tissues and cells. Short stature homeobox 2 (SHOX2) was predicted and verified as the downstream target gene of miR-233-3p. Inhibiting the expression of SHOX2 could significantly reduce the malignant behaviors of OSCC cells. The proliferation, migration and anti-apoptotic abilities of miR-233-3p overexpressed cells were obviously limited. However, the recovery of SHOX2 counteracted the beneficial effect of miR-233-3p. CONCLUSIONS MiR-223-3p acted as a tumor suppressor gene in OSCC by targeting SHOX2. Our findings revealed that miR-223-3p/SHOX2 axis could be a potential therapeutic target for OSCC.

Abstract
From April 2017 to April 2018, three male patients aged 46-71 years with large area burns were treated in our hospital. Acute acalculous cholecystitis (AAC) symptoms of the patients began to appear 15-81 days after injury. AAC was diagnosed 24-81 days after injury. Ultrasound-guided percutaneous transhepatic cholecystostomy was performed 26-82 days after injury. The symptoms subsided in 2 patients, and cholecystectomy was performed in 1 patient with gallbladder perforation 94 days after injury. The patients were cured and discharged 41-118 days after injury. No recurrence of cholecystitis occurred during 8-9 months of follow-up after discharge.

Abstract
In this study, 1 065 infants and young children aged 24 months below in ethnic minorities gathering in poor rural areas in poor rural areas of Liangshan Yi Autonomous Prefecture of Sichuan Province and Gannan Tibetan Autonomous Prefecture of Gansu Province were investigated for their anemia status from October to November 2014, and the association between anemia and the utilization of maternal and child health services was analyzed. The prevalence of anemia in this area was 52.68%(561/1 065). After the adjustment of socio-demographic characteristics of mothers and infants, compared with infants aged 2-5 months, Han ethnic group, and infants whose mother was not anemic, the OR(95%CI) values of infant anemia for infants aged 6-12 months, 13-8 months, 19-24 months, ethnic minorities group, and infants whose mother was anemic were 11.65 (7.09-19.14), 9.91 (5.99-16.38), 5.87 (3.39-10.16), 1.55 (1.10-2.18) and 1.52 (1.14-2.04), respectively; Compared with infants whose child examination times not up to standard, and who were not only non-hospital delivered but also received inadequate number of inoculation, the OR (95%CI) values of infant anemia for infants whose child examination times up to standard, and who were not only hospital delivered but also received adequate number of inoculation were 0.60 (0.38-0.94) and 0.71 (0.52-0.98), respectively. The infants anemia is associated with the utilization of maternal and child health services.

Abstract
The paper discusses how citizen science within an ecosystem services (ESS) framework may enhance evaluation of de-centralized water solutions. In a demonstration case in Oslo, citizens were engaged in long-term monitoring and evaluation of two solutions for treatment of combined sewer overflows. The citizens participated in the design of the study, systematic observations, and final evaluation, via interviews and workshops. A wealth of real-time information was collected, supplementing simulation data and water sampling results. The concept of ESS drew attention to benefits that tend to be ignored in standard evaluations. It is, however, most elaborate for ecological services, and less developed for social aspects. Involving the citizens complemented the framework in these areas, while providing new insights into the contextual interactions influencing ESS and benefits of local treatment. Both solutions, a cross-flow lamella settler and a high-rate filtration system, were quite efficient in removing suspended solids, with a strong impact on visual appearance. A range of wider benefits were identified. These were difficult to monetize, but the citizens' evaluation provided an alternative measure. The study highlights the benefits of citizen science in local water management and suggests the need for more research on beneficiaries in ESS evaluation.

Abstract
The performance of an interband cascade laser based laser heterodyne radiometer (LHR) is demonstrated in ground-based solar occultation mode. High-resolution (0.0033 cm-1) transmission spectra near 3.53 μm were obtained for simultaneous atmospheric observations of H2O and CH4. Combined with the preprocessed measurement data (acquired at Hefei, China, on June 21th 2016), an optimal estimation method based retrieval algorithm is developed for data retrieval and error analysis. By considering the corrected atmospheric parameters, vertical profiles of H2O and CH4 are retrieved. Finally, the measured total column abundance and XCH4 were calculated to be 1.87 ± 0.02 ppm and 1.88 ± 0.02 ppm, respectively. The interband cascade laser-based laser heterodyne radiometer that is demonstrated in this manuscript has high potential for use in the development of compact, robust, and unattended LHR for spacecraft, airborne or ground-based atmospheric sensing.

Abstract
Combined sewer overflows (CSOs) pollute receiving waters and have a negative impact on ecosystem services. In urban areas rehabilitation of the sewer system to avoid CSOs is associated with high investment costs. Furthermore, not all CSOs can be closed due to the need for hydraulic reliability of the system. Local treatment of CSO with high rate filtration offers an alternative to rehabilitation of the sewer system that is flexible with respect to design and has lower investment cost than separating sewage and storm water runoff. Results from DESSIN, a 4-year EU demonstration project, are presented. The results showed on average 50% removal of particulate matter during CSO events, with higher removal (80%) in the initial first flush period. Other constituents, for example heavy metals, were removed through their association with particles. Potential impacts on ecosystem services in the catchment and the sustainability of the solution were assessed.

Abstract
The implantation of noble gas atoms into metals at high gas concentrations can lead to the self-organization of nanobubbles into superlattices with symmetry similar to the metal host matrix. Here, we examine the influence of implantation parameters on the formation and structure of helium gas bubble superlattices within a tungsten host matrix to uncover mechanistic insight into the formation process. The determination of the size and symmetry of the gas bubbles was performed using a combination of small angle x-ray scattering and transmission electron microscopy. The former was demonstrated to be particularly useful in determining size and structure of the gas bubble superlattice as a function of irradiation conditions. Prior to the formation of a superlattice, we observe a persistent substructure characterized by inter-bubble spacings similar to those observable when the gas bubble superlattice has formed with very large ordering parameters. As the implantation fluence increases, the inter-bubble ordering parameter decreases, indicating improved ordering, until a superlattice is formed. Multiple implantation-specific differences were observed, including a temperature-dependent superlattice parameter that increases with increasing temperature and a flux-dependent superlattice parameter that decreases with increasing flux. The trends quantified here are in excellent agreement with our recent theoretical predictions for gas bubble superlattice formation and highlight that superlattice formation is strongly dependent on the diffusion of vacancy and implanted He atoms.

Abstract
Abstract
Adipose stromal/stem cells (ADSCs) could regulate malignancy behaviors of breast cancer, which was due to adipose-derived cytokines in part, such as leptin and resistin. Recently, peptides have been demonstrated to be potential targets for cancer therapy. It's valuable to analyze the characters of adipose-secreted peptides systematically. In this study, we isolated primary adipocytes from adipose tissue adjacent to breast tumor and breast benign lesions respectively, and then co-cultured breast cancer cells MCF-7 with tumor adjacent adipocytes (TAAs)/breast benign adipocytes (BBAs) separately. Compared to BBAs, TAAs could promote proliferation and migration ability of MCF-7. Then we extracted and purified peptides from supernatant of TAAs and BBAs using ultrafiltration, and the effects of TAAs-derived peptides compound on breast cancer cells appeared accordance with the adipose cells. 100 peptides, which were derived from 90 protein precursors, were found to be differentially secreted between TAAs and BBAs by LC-MS/MS (p < 0.05). Gene Ontology (GO) and Pathway analyses appeared that these altered peptides were mainly contributed to cell adhesion, and regulation of Ras-protein signal transduction. These results showed that these differentially secreted peptides could regulate breast cancer cell malignancy, which indicated that they could be potential therapeutic targets and diagnostic bio-marker for breast cancer.

Abstract
Abstract
Background: Resistance to trastuzumab remains a common challenge to HER-2 positive breast cancer. Up until now, the underlying mechanism of trastuzumab resistance is still unclear. tRNA-derived small non-coding RNAs, a new class of small non-coding RNA (sncRNAs), have been observed to play an important role in cancer progression. However, the relationship between tRNA-derived fragments and trastuzumab resistance is still unknown.
Methods:We detected the levels of tRNA-derived fragments expression in normal breast epithelial cell lines, trastuzumab-sensitive and -resistant breast cancer cell linesusing high-throughput sequencing.qRT-PCR was conducted to validate the differentially expressed fragments in serums from trastuzumab-sensitive and -resistant patients. A receiver operating characteristic (ROC) curve analysis was performed to evaluate the power of specific tRNA-derived fragments.Progression-free survival (PFS) was analyzed using Cox-regression.
Results:Our sequence results showed that tRNA-derived fragments were differentially expressed in the HBL-100, SKBR3, and JIMT-1 cell lines. tRF-30-JZOYJE22RR33 and tRF-27-ZDXPHO53KSN were found significantly upregulated in trastuzumab-resistant patients compared to sensitive individuals, and the ROC analysis showed that tRF-30-JZOYJE22RR33 and tRF-27-ZDXPHO53KSN were correlated with trastuzumab resistance. In a multivariate analysis, higher levels of tRF-30-JZOYJE22RR33 and tRF-27-ZDXPHO53KSN expression were associated with significantly shorter PFS in patients with metastatic HER-2 positive breast cancer.
Conclusion: Our results suggest that tRF-30-JZOYJE22RR33 and tRF-27-ZDXPHO53KSN play important roles in trastuzumab resistance. Patients with high levels of tRF-30-JZOYJE22RR33 and tRF-27-ZDXPHO53KSN expression benefitted less from trastuzumab-based therapy than those that express lower-levels of these molecules. tRF-30-JZOYJE22RR33 and tRF-27-ZDXPHO53KSN may be potential biomarkers and intervention targets in the clinical treatment of trastuzumab-resistant breast cancer.

Abstract
Abstract
Background/Objective:
Breast carcinomas with HER2 receptor amplification and overexpression account for approximately 20% of all breast cancers, which also confer more aggressive phenotypes and are associated with poor prognosis. Up to 23% of patients with early-stage HER2-positivie (HER2+) breast cancer treated with adjuvant chemotherapy and trastuzumab experience disease recurrence within 10 years, highlighting the importance of identifying which HER2+ patients respond to this treatment and those that do not. Efforts to identify biomarkers predictive of response in the initial breast tumor biopsy to trastuzumab have been complicated by the clinical and biological heterogeneity of HER2+ tumors. Therefore, we aim to develop a trastuzumab-resistant (TRR) signature which could faithfully predict patients' response to this treatment using transcriptome profiles in engineered cell line models. We further investigated the possible mechanisms mediating TRR by bioinformatics and biochemical approaches in order to reveal promising new therapeutic targets TRR HER2+ patients.
Methods:
Publically available transcriptome profile (GSE15043) of genetically engineered isogenic models of TRR cell lineages in mammary HER2+ BT474 cells (initially trastuzumab sensitive, TRS) are used to generate the TRR signature using Bioconductor in R. Performance of this gene signature was tested on independent in vitro and in vivo transcriptome datasets using Receiving Operation Curve (ROC). Signature scores were determined by calculating the correlations between medium centered gene expression levels within the signature and gene expression levels for that gene within a given sample, following quantile normalization. Three pairs of TRR vs. TRS cell lines were used for accessing their profiles of proliferation, migration, genomic stability and signature scores. Genes of interest in the signature were further perturbed in TRR cells for drug sensitivity assay.
Results and Conclusion:
TRR cell lines have significant more malignant phenotypes in comparison to TRS cell lines, indicated by their shorter doubling time, faster migration and more innate double strain breaks. 43 differentially regulated genes between BT474R (engineered TRR cell line) and BT474 are identified and the area under the curve (AUC) of ROCs are 0.75, 0.88, and 0.84 for microarray data of CCLE, RNA sequencing data of CCLE and patient dataset GSE62327, respectively. In addition, TRR signature is significantly enriched in non-responding cell lines, TRR patients and patients relapsed within 3 years after treatment. TRR cell lines – BT474-C5, T47D and HCC1954 exhibit significant higher TRR signature scores in comparison to TRS cell lines by the 43-gene PCR array. Interestingly, overexpression of one of gene candidates, S100A8, which is also a key cytokine in regulating antibody-dependent cytotoxicity (ADCC), conferred trastuzumab resistance in TRR cell lines. This finding could assist in clinicians' diagnosis and selection of treatments for HER2+ breast cancer with a more accurate risk evaluation and offering promising alternatives such as immunotherapy.

Abstract
Pig umbilical hernia (UH) affects pig welfare and brings considerable economic loss to the pig industry. To date, the molecular mechanisms underlying pig UH are still poorly understood. To identify potential loci for susceptibility to this disease, we performed a genome-wide association study in an Erhualian × Shaziling F2 intercross population. A total of 45 animals were genotyped using Illumina Porcine SNP60 BeadChips. We observed a SNP (rs80993347) located in the calpain-9 (CAPN9) gene on Sus scrofa chromosome 14 that was significantly associated with UH (P = 1.97 × 10-10 ). Then, we identified a synonymous mutation rs321865883 (g.20164T>C) in exon 10 of the CAPN9 gene that distinguished two affected individuals (CC) from their normal full-sibs (TC). Finally, quantitative polymerase chain reaction was explored to investigate the mRNA expression profile of the CAPN9 gene in 12 tissues in Yorkshire pigs at different developmental stages (3, 90 and 180 days). CAPN9 showed high expression levels in the gastrointestinal tract at these three growth stages. The results of this study indicate that the CAPN9 gene might be implicated in UH. Further studies are required to establish a role of CAPN9 in pig UH.

Abstract
Hepatocellular carcinoma (HCC) develops in the context of chronic inflammatory liver disease and has an extremely poor prognosis. An immunosuppressive tumor microenvironment may contribute to therapeutic failure in metastatic HCC. Here, we identified unique molecular signatures pertaining to HCC disease progression and tumor immunity by analyzing genome-wide RNA-Seq data derived from HCC patient tumors and non-tumor cirrhotic tissues. Unsupervised clustering of gene expression data revealed a gradual suppression of local tumor immunity that coincided with disease progression, indicating an increasingly immunosuppressive tumor environment during HCC disease advancement. IHC examination of the spatial distribution of CD8+ T cells in tumors revealed distinct intra- and peri-tumoral subsets. Differential gene expression analysis revealed an 85-gene signature that was significantly upregulated in the peri-tumoral CD8+ T cell-excluded tumors. Notably, this signature was highly enriched with components of underlying extracellular matrix, fibrosis, and epithelial-mesenchymal transition (EMT). Further analysis condensed this signature to a core set of 23 genes that are associated with CD8+ T cell localization, and were prospectively validated in an independent cohort of HCC specimens. These findings suggest a potential association between elevated fibrosis, possibly modulated by TGF-β, PDGFR, SHH or Notch pathway, and the T cell-excluded immune phenotype. Indeed, targeting fibrosis using a TGF-β neutralizing antibody in the STAM™ model of murine HCC, we found that ameliorating the fibrotic environment could facilitate redistribution of CD8+ lymphocytes into tumors. Our results provide a strong rationale for utilizing immunotherapies in HCC earlier during treatment, potentially in combination with anti-fibrotic therapies.

Abstract
Ginseng ( C.A. Mey.) is one of the most important medicinal herbs for human health and medicine, for which ginsenosides are the major bioactive components. The cytochrome P450 genes, , form a large gene superfamily; however, only three genes have been identified from ginseng and shown to be involved in ginsenoside biosynthesis, indicating the importance of the gene superfamily in the process. Here we report genome-wide identification and systems analysis of the genes in ginseng, defined as genes. We identified 414 genes, including the three published genes. These genes formed a superfamily consisting of 41 gene families, with a substantial diversity in phylogeny and dramatic variation in spatiotemporal expression. Gene ontology (GO) analysis categorized the gene superfamily into 12 functional subcategories distributing among all three primary functional categories, suggesting its functional differentiation. Nevertheless, the majority of its gene members expressed correlatively and tended to form a coexpression network and some of them were commonly regulated in expression across tissues and developmental stages. These results have led to genome-wide identification of genes useful for genome-wide identification of the genes involved in ginsenoside biosynthesis in ginseng and provided the first insight into how a gene superfamily functionally differentiates and acts correlatively in plants.

Abstract
Objective: To evaluate the clinical value of preoperative (18)F-Fludeoxyglucose ((18)F-FDG PET-CT) in lymphatic metastasis diagnosis of cutaneous melanoma on extremities and trunk. Methods: 112 patients with cutaneous melanoma pathologically of extremities and trunk from January 2006 to December 2016, who received (18)F-FDG PET-CT examination preoperatively, were retrospectively reviewed. The correlations between the maximal diameters of lymph nodes, the maximal standard uptake value (SUV) and the diagnostic impression grades of PET-CT examination, and the final pathological diagnosis were analyzed. The correlations between Breslow thickness of primary lesions and the diagnostic impression of PET-CT examination were also analyzed. All the above were analyzed with Receiver Operating Characteristic (ROC) curve to get the cut-off value. Based on the final results of pathological diagnosis of lymph nodes as the golden standard, the statistically significant indicators of ROC curve analysis were used to evaluate the diagnostic effect, as well as to calculate the sensitivity, specificity and accuracy. With gender, age, maximal diameter of lymph nodes, maximal SUV, diagnosis impressions, and Breslow thickness as the independent variables and pathological diagnosis results of lymph nodes as the dependent variable, two-class stepwise Logistic regression analysis was used to determine the independence of diagnostic indicators. ROC curve analysis and log rank test were used to analyze the relationship between Breslow thickness and patient survival. Results: To evaluate melanoma patients' lymph node status, the results of ROC curve analysis showed that the area under the curve of lymph node maximal diameter, maximal SUV, diagnosis impression of PET-CT examinations were 0.789, 0.786 and 0.816, respectively (all P<0.05). The cut-off values were 0.85 cm, 1.45 and 2.5, respectively. The sensitivity of the cut-off values to determine the status of lymph nodes in melanoma patients were 71.4%, 64.9% and 72.1% respectively, and the specificities were 85.2%, 88.7% and 87.0% respectively. Multivariate Logistic regression analysis showed that PET-CT diagnosis impressions had independent diagnostic significance for the lymph node status of melanoma patients (OR=11.296, 95%CI: 2.550~50.033). The area under the curve of Breslow thickness evaluating PET-CT diagnostic impression is 0.664 (P=0.042) and the cut-off value was 4.25 mm. The survival rate of the patients with Breslow thickness ≥ 4.25 mm was lower than that in the group <4.25 mm (P=0.006). Conclusions: (18)F-FDG PET-CT can help to evaluate metastases and make treatment decisions for cutaneous melanoma of extremities and trunk, especially for patients whose primary lesion's Breslow thickness has reached more than 4.25 mm. For the patients whose maximal SUV of regional lymph node is higher than 1.45 and short diameter of the largest lymph node is larger than 0.85cm, the possibility of metastases should be considered.

Abstract
Pre-eclampsia is associated with increased levels of cholesterol and uric acid and an inflamed placenta expressing danger-sensing pattern recognition receptors (PRRs). Crystalline cholesterol and uric acid activate the PRR Nod-like receptor protein (NLRP)3 inflammasome to release interleukin (IL)-1β and result in vigorous inflammation. We aimed to characterize crystal-induced NLRP3 activation in placental inflammation and examine its role in pre-eclampsia. We confirmed that serum total cholesterol and uric acid were elevated in pre-eclamptic compared to healthy pregnancies and correlated positively to high sensitivity C-reactive protein (hsCRP) and the pre-eclampsia marker soluble fms-like tyrosine kinase-1 (sFlt-1). The NLRP3 inflammasome pathway components (NLRP3, caspase-1, IL-1β) and priming factors [complement component 5a (C5a) and terminal complement complex (TCC)] were co-expressed by the syncytiotrophoblast layer which covers the placental surface and interacts with maternal blood. The expression of IL-1β and TCC was increased significantly and C5a-positive regions in the syncytiotrophoblast layer appeared more frequent in pre-eclamptic compared to normal pregnancies. In-vitro activation of placental explants and trophoblasts confirmed NLRP3 inflammasome pathway functionality by complement-primed crystal-induced release of IL-1β. This study confirms crystal-induced NLRP3 inflammasome activation located at the syncytiotrophoblast layer as a mechanism of placental inflammation and suggests contribution of enhanced NLRP3 activation to the harmful placental inflammation in pre-eclampsia.

Abstract
Abstract
Background
Variants of the leucine-rich repeat kinase 2 (LRRK2) are associated with an increased susceptibility to Parkinson disease but also Crohn’s disease (CD).
Aims
The present research is designed to develop a comprehensive understanding of the role of LRRK2 in immune system modulation, and how dysfunction of this pathway may lead to the development of CD.
Methods
WT and LRRK2-deficient neutrophil were infected with Gram-positive Bacteria (Listeria monocytogenes-LM) in a gentamicin protection assays and colony-forming unit assessment will determine the competence of LRRK2 deficient cells for bacterial phagocytosis as well as killing capacity). To examine how LRRK2 is involved in the generation of ROS during the respiratory burst, we will first examine if neutrophil from LRRK2-KO mice have altered ROS generation upon infection with LM and addition of PMA. We evaluate in vitro the ability of neutrophils from LRRK2-KO versus WT mice to transmigrate in vitro in a transwell assay using fMLP as a chemattractant. Also, we investigate the peritoneal cells (by FACS analysis) after injection of different microbial stimuli including FK105 (NOD1 ligand), MDP (NOD2 ligand) and LPS (TLR4 ligand) and anti-cd3 model of ielitis.
Results
We found that LRRK2 KO mice have a defect in migration of neutrophils to the peritoneal cavity after injection of different microbial stimuli including FK10565 (NOD1 ligand), MDP (NOD2 ligand) and LPS (TLR4 ligand). Neutrophils from LRRK2 mice were compromised in their ability to transmigrate in vitro in a transwell assay using fMLP as a chemoattractant. Chemotaxis was also compromised. In parallel, we designed experiments to examine reactive oxygen species (ROS) produced in response to infection of myeloid cells with bacteria. Neutrophils from LRRK2 KO mice infected with Listeria monocytogenes were less able to restrict bacteria growth compared to WT cells. Consistent with these findings, cells from LRRK2 KO mice produced lower levels of ROS following bacterial infection. In order to determine whether myeloid cell migration is compromised in vivo during inflammation, we performed experiments in WT and KO mice looking at different models of ileitis/colitis.
Conclusions
With this work we will further characterize the role of LRRK2 in intestinal homeostasis and mucosal barrier maintenance, including how its deficiency may predispose an individual to developing CD.

Abstract
Most genes in a genome exist in the form of a gene family; therefore, it is necessary to have knowledge of how a gene family functions to comprehensively understand organismal biology. The receptor-like kinase (RLK)-encoding gene family is one of the most important gene families in plants. It plays important roles in biotic and abiotic stress tolerances, and growth and development. However, little is known about the functional differentiation and relationships among the gene members within a gene family in plants. This study has isolated 563 RLK genes (designated as PgRLK genes) expressed in Jilin ginseng (Panax ginseng C.A. Meyer), investigated their evolution, and deciphered their functional diversification and relationships. The PgRLK gene family is highly diverged and formed into eight types. The LRR type is the earliest and most prevalent, while only the Lec type originated after P. ginseng evolved. Furthermore, although the members of the PgRLK gene family all encode receptor-like protein kinases and share conservative domains, they are functionally very diverse, participating in numerous biological processes. The expressions of different members of the PgRLK gene family are extremely variable within a tissue, at a developmental stage and in the same cultivar, but most of the genes tend to express correlatively, forming a co-expression network. These results not only provide a deeper and comprehensive understanding of the evolution, functional differentiation and correlation of a gene family in plants, but also an RLK genic resource useful for enhanced ginseng genetic improvement.

Abstract
Increased production of long-chain unsaturated fatty acids (LCUFA) can have a positive effect on the nutritional value of ruminant milk for human consumption. In nonruminant species, fatty acid elongase 5 (ELOVL5) is a key enzyme for endogenous synthesis of long-chain unsaturated fatty acids. However, whether ELOVL5 protein plays a role (if any) in ruminant mammary tissue remains unclear. In the present study, we assessed the mRNA abundance of ELOVL5 at 3 stages of lactation in goat mammary tissue. Results revealed that ELOVL5 had the lowest expression at peak lactation compared with the nonlactating and late-lactating periods. The ELOVL5 was overexpressed or knocked down to assess its role in goat mammary epithelial cells. Results revealed that ELOVL5 overexpression increased the expression of perilipin2 (PLIN2) and decreased diacylglycerolacyltransferase 2 (DGAT2) and fatty acid desaturase 2 (FADS2) mRNA, but had no effect on the expression of DGAT1, FADS1, and stearoyl-CoA desaturase 1 (SCD1). Overexpression of ELOVL5 decreased the concentration of C16:1n-7, whereas no significant change in C18:1n-7 and C18:1n-9 was observed. Knockdown of ELOVL5 decreased the expression of PLIN2 but had no effect on DGAT1, DGAT2, FADS1, FADS2, and SCD1 mRNA expression. Knockdown of ELOVL5 increased the concentration of C16:1n-7 and decreased that of C18:1n-7. The alterations of expression of genes related to lipid metabolism after overexpression or knockdown of ELOVL5 suggested a negative feedback regulation by the products of ELOVL5 activation. However, the content of triacylglycerol was not altered by knockdown or overexpression of ELOVL5 in goat mammary epithelial cells, which might have been due to the insufficient availability of substrate in vitro. Collectively, these are the first in vitro results highlighting an important role of ELOVL5 in the elongation of 16-carbon to 18-carbon unsaturated fatty acids in ruminant mammary cells.

Abstract
This study investigated the prevalence of MRSA in samples taken in households, with and without backyard pigs in villages in a rural area of Shandong Province, China. Community-associated MRSA and livestock-associated MRSA, belonging to ST59 and ST9, respectively, were identified in both humans and pigs. The genotypic and phenotypic comparison of isolates indicates that bidirectional transmission of MRSA has occurred between humans and pigs in the villages.

Abstract
Objective: To investigate the role of bone marrow mesenchymal stem cells (BMSCs) with CTLA4Ig and CD40LIg gene modification in rejection reaction after liver transplantation in rats and possible mechanisms. Methods: The modified Kamada's two-cuff technique was used to establish a Lewis-BN rat model of orthotopic liver transplantation, and a total of 75 rats were randomly divided into groups A, B, C, D, and E, with 15 rats in each group. The rats in group A (control group) were given infusion of isotonic saline via the portal vein during liver transplantation, those in group B (BMSC group) were given infusion of BMSCs via the portal vein during liver transplantation, those in group C (BMSCs with CTLA4Ig gene modification) were given infusion of BMSCs carrying the CTLA4Ig gene via the portal vein during liver transplantation, those in group D (BMSCs with CD40LIg gene modification) were given infusion of BMSCs carrying the CD40LIg gene via the portal vein during liver transplantation, and those in group E (BMSCs with CTLA4Ig and CD40LIg gene modification) were given infusion of BMSCs carrying CTLA4Ig and CD40LIg gene modification via the portal vein during liver transplantation. Postoperative survival and change in liver function were observed. HE staining was used to observe the pathomorphological changes of the graft liver, and ELISA was used to measure the levels of interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-10 (IL-10), and interferon-γ (IFN-γ) in peripheral blood. A one-way analysis of variance was used for comparison of means of multiple samples, and the Kaplan-Meier survival curve analysis was used for comparison of survival rates between multiple groups. Results: Group E had a significantly longer survival time after surgery than groups A, B, C, and D (P < 0.05), groups C and D had a significantly longer survival time than groups A and B (P < 0.05), and there was no significant difference between groups C and D (P > 0.05). On day 10 after surgery, group A had significantly higher levels of alanine aminotransferase and total bilirubin than the other four groups (P < 0.05). HE staining showed severe rejection reaction in group A, moderate rejection reaction in group B, and mild rejection reaction in groups C and D; pathological examination showed no marked rejection reaction in group E. Group A had significant increases in the levels of IL-2 and IFN-γ and significant reductions in the levels of IL-4 and IL-10 after surgery compared with the other four groups (all P < 0.05). Conclusion: Infusion of BMSCs with modification of both CTLA4Ig and CD40LIg genes can significantly inhibit acute rejection reaction after liver transplantation in rats and effectively prolong the survival time of the graft liver, with a better effect than infusion of BMSCs alone or BMSCs with modification of CTLA4Ig or CD40LIg gene.

Abstract
Purpose To discuss the intraoperative and postoperative complications of combining phacoemulsification and foldable intraocular lens (IOL) implantation with pars plana vitrectomy in eyes with significant cataract and coexisting vitreoretinal diseases. Methods This retrospective study consisted of 186 eyes of 149 patients with various vitreoretinal abnormalities and visually significant cataracts. Vitreoretinal surgery was combined with clear corneal phacoemulsification and foldable IOL implantation. Main outcome measures were the intraoperative and postoperative complications at from 6 to 56 months. Results The most common intraoperative complication was iatrogenic retinal hole (5.3%), transient corneal edema (3.2%), and posterior capsule break (2.1%). The most common postoperative complication was posterior capsule opacification (21.5%) and elevated intraocular pressure (9.7%), macular edema (8.1%), fibrinous reaction (6.9%), vitreous hemorrhage (3.7%), posterior synechiae (3.7%), and recurrent retinal detachment (3.2%). Postoperatively, in 162 eyes (87.1%), visual acuity improved by 3 lines or more on the Snellen chart. In 14 eyes (7.5%), vision remained within 3 lines of preoperative levels and in 10 eyes (5.3%), vision had decreased at the last follow-up. Conclusions Postoperative complications did not increase significantly in the combined phacoemulsification and vitreoretinal surgery. Combined vitreoretinal surgery and phacoemulsification with foldable IOL implantation is safe and effective in treating vitreoretinal abnormalities coexisting with cataract. Based on extensive experience with the combined procedure, the authors suggest that combined surgery is recommended in select patients having simultaneous vitreoretinal pathologic changes and cataract.

Abstract
Liver sinusoidal endothelial cells are a major group of nonparenchymal cells in the liver and are involved in immunological surveillance of the liver through the expression of various scavenger receptors and pattern recognition receptors. However, in case of several physiological states, viral infections, and tumor environment, liver sinusoidal endothelial cells maintain immune tolerance in the liver through various mechanisms and cause persistent viral infection and tumor metastasis. This article reviews the mechanisms of immune tolerance of CD4 + T cells and CD8 + T cells in the liver induced by liver sinusoidal endothelial cells.

Abstract
Iron (Fe) is a vital trace element in plants, and deficiency of this element in apple trees can reduce fruit quality. Nicotianamine (NA) is known to play an important role in Fe transport and endogenous hormone balance. In the present study, we investigated the role of a nicotianamine synthase 1 gene (MxNas1) in an apple species, Malus xiaojinensis, that has a more Fe-efficient genotype than other apple species and ecotypes. To characterise the response of M. xiaojinensis to Fe deficiency, we used quantitative Q-PCR to determine the level of expression of MxNas1 and Western blot to measure protein levels. Immunohistochemical staining and GFP fluorescence localisation of the MxNAS1 protein were also carried out. HPLC and polarised absorption spectrophotometry were performed to investigate the effects of overexpression of MxNas1 in order to elucidate the role of MxNAS1 in the cellular uptake of active Fe in tobacco suspension cells. We found that MxNas1 expression and protein levels were higher under Fe deficiency stress than under Fe sufficiency. Immunohistochemical staining showed that MxNAS1 was localised mainly in the epidermal and vascular tissues of the roots, vascular tissues of the stem and palisade cells of mature leaves, and in parenchyma cells of young leaves. MxNAS1 was mainly localised in the plasma membranes and vesicles of protoplasts. In addition, overexpression of MxNas1 in stable transgenic tobacco cells increased NA and active Fe content under Fe sufficiency. The results suggest that MxNas1 expression in M. xiaojinensis is induced in response to Fe deficiency stress, resulting in higher levels of the protein. MxNAS1 may be involved in the redistribution of Fe in M. xiaojinensis under Fe deficiency.

Abstract
Objective: To evaluate the effect of different placement of mesial implants in edentulous jaws on the stress of the implant and the surrounding bone tissue by three-dimensional (3D)finite element analysis. Methods: Cone-beam CT data of mandibular edentulous patients was transferred into Mimics 17.0 and UG NX8.5 software, and three groups of 3D solid model were established: two mesial implants were implanted in the anterior region of the mandible (bilateral central incisor, lateral incisor, canine), and two distal oblique implant with 30° were implanted in the mandibular second premolar area(5 mm near the mental foramen). Set mandible 3D model with 4 implant by using UG NX8.5 software, produced 3 groups (mandible Ⅰ-Ⅲ). We took dynamic loading on models with help of software Abaqus 6.12, working side posterior teeth loading was set to 150 N and the simulation cycle was 0.875 s. The first stage: 0.000 s to 0.130 s, the lower jaw moves outward (moving toward the side of the work), with no contact between the upper and lower teeth; the second stage: 0.130 s to 0.150 s, mandibular upward, the same tooth tip of the working side were relative, the loading position were the posterior buccal tip, tongue tip; the third stage: 0.150 s to 0.260 s, the buccal slopes of buccal tips of mandibular posterior teeth glide along the lingual slopes of buccal tips of maxillary posterior teeth, the loading force was from the buccal side to the lingual side, the long axis of the tooth was 45°, loaded on the buccal slopes of buccal tips of posterior teeth; the fourth stage: 0.260 s to 0.300 s, the lingual slopes of buccal tips of mandibular posterior teeth glide along the buccal slopes of the tongue tips of maxillary posterior teeth, separate from the tip of the tooth at half the length, the loading force was from the lingual side to the buccal side, the long axis of the tooth was 45°, loaded on the lingual slopes of buccal tips of posterior teeth; the fifth stage: 0.300 s to 0.875 s, at the unloading stage, mandibular posterior teeth were separated from the maxillary teeth and returned to the intercuspal position. The loading position varied according to the mastication cycle. The stress distribution of implant and surrounding bone tissue at different stages of each model were observed. Results: From the early stage to chew occlusal contact to the end of the mastication cycle, three groups of models were displayed: the stress of distal implants was greater than that of mesial implants and the neck stress reached the maximum and gradually decreased to the root tip. The stress of distal implant bone was greater than that of mesial implant bone and the stress of distal bone of distal implant was greater than that of mesial bone of distal implant. All the stress peak showed a gradual increase, and the stress reach the maximum at the fourth stage. In the 3 models, the bone stress around the distal implant of model of the anterior implant located in the lateral incisor region was the lowest. The peak stress of cortical bone of the distal position of implant was 58.7 MPa. The bone stress around the distal implant of model of the anterior implant located in the canine region reached the maximum, and the peak stress of cortical bone of the distal position of implant was 135.6 MPa. Conclusions: When mesial implants of edentulous jaws located in the lateral incisor region, it is good for stress dispersion.
