Abstract
Hepatocellular carcinoma (HCC) is the most widespread histological form of primary liver cancer, and it faces great diagnostic and therapeutic difficulties owing to its tumor diversity. Herein, we aim to establish a unique prognostic molecular subtype (MST) and based on this to find potential therapeutic targets to develop new immunotherapeutic strategies. Using calcium channel molecules expression-based consensus clustering, we screened 371 HCC patients from The Cancer Genome Atlas to screen for possible MSTs. We distinguished core differential gene modules between varying MSTs, and Tumor Immune Dysfunction and Exclusion scores were employed for the reliable assessment of HCC patient immunotherapeutic response rate. Immunohistochemistry and Immunofluorescence staining were used for validation of predicted immunotherapy outcomes and underlying biological mechanisms, respectively. We identified two MSTs with different clinical characteristics and prognoses. Based on the significant differences between the two MSTs, we further identified Follistatin-like 3 (FSTL3) as a potential indicator of immunotherapy resistance and validated this result in our own cohort. Finally, we found that FSTL3 is predominantly expressed in HCC stromal components and that it is a factor in enhancing fibroblast-M2 macrophage signaling crosstalk, the function of which is relevant to the pathogenesis of HCC. The presence of two MSTs associated with the calcium channel phenotype in HCC patients may provide promising directions for overcoming immunotherapy resistance in HCC, and the promotion of FSTL3 expressed in stromal components for HCC hyperfibrosis may be responsible for the poor response rate to immunotherapy in Cluster 2 (C2) patients.

Abstract
Objective: To investigate the clinical characteristics of patients with acquired aplastic anemia (AA) accompanied by abnormal antinuclear antibody (ANA) and autoantibodies and their effects on the efficacy of immunosuppressive therapy (IST). Method: A retrospective case-control study was conducted, analyzing the clinical data of 291 patients with AA who underwent IST and were screened for autoantibodies at initial diagnosis between January 2018 and December 2019 at Blood Diseases Hospital, Chinese Academy of Medical Sciences. According to the titer of ANA at the initial diagnosis, extracted nuclear antigen antibodies (ENAs) abnormality and the change of ANA titer after treatment, the treatment responses of 3 months and 6 months after IST were compared. The correlation between clinical features and ANA abnormality was analyzed by univariate and multivariate logistic regression analysis. The parameters of univariate analysis P<0.1 were included in multivariate analysis, stepwise regression analysis and subgroup analysis. Results: A total of 291 patients were included in the study, of which 145 (49.83%) were male. Among all patients, 147 (50.52%) tested positive for ANA at initial diagnosis, with titers of 1∶100, 1∶320, and 1∶1 000 observed in 94, 47, and 6 cases, respectively. Female gender, older age, presence of paroxysmal nocturnal hemoglobinuria (PNH) clone, and higher levels of IgG, IgA, and thyroid hormone were significantly associated with ANA positivity at initial diagnosis, while white cell counts, reticulocytes, and free triiodothyronine were significantly lower than that of ANA-negatively patients (all P<0.05). Furthermore, logistic regression analyses revealed that female gender (OR=1.980, 95%CI 1.206-3.277), older age (OR=1.017, 95%CI 1.003-1.032), and presence of PNH clone (OR=1.875, 95%CI 1.049-3.408) were independent risk factors for ANA positivity at initial diagnosis. Subgroup analysis indicated that the risk of ANA positivity at initial diagnosis was even higher in PNH clone-positive patients in the subgroups of females (OR=1.24, 95%CI 1.02-1.51), severe AA (OR=1.26, 95%CI 1.07-1.47), and age≥40 years (OR=1.26, 95%CI 1.05-1.52) (all P<0.05). However, ANA titers at initial diagnosis, presence of other abnormal ENAs, and changes in ANA titers after treatment with IST were not correlated with treatment response (all P>0.05). Conclusions: Approximately 50% of patients with AA had abnormal ANA, and their presence was significantly associated with female gender, older age, and presence of PNH clone at initial diagnosis. However, the presence of abnormal ANA and changes in ANA titers after treatment did not affect the efficacy of IST in patients with AA.

Abstract
Objective: To report gene mutations in nine patients with hereditary elliptocytosis (HE) and analyze the characteristics of pathogenic gene mutations in HE. Methods: The clinical and gene mutations of nine patients clinically diagnosed with HE at Institute of Hematology & Blood Diseases Hospital from June 2018 to February 2022 were reported and verified by next-generation sequencing to analyze the relationship between gene mutations and clinical phenotypes. Results: Erythrocyte membrane protein gene mutations were detected among nine patients with HE, including six with SPTA1 mutation, one with SPTB mutation, one with EPB41 mutation, and one with chromosome 20 copy deletion. A total of 11 gene mutation sites were involved, including 6 known mutations and 5 novel mutations. The five novel mutations included SPTA1: c.1247A>C (p. K416T) in exon 9, c.1891delG (p. A631fs*17) in exon 15, E6-E12 Del; SPTB: c.154C>T (p. R52W) ; and EPB41: c.1636A>G (p. I546V) . Three of the six patients with the SPTA1 mutation were SPTA1 exon 9 mutation. Conclusion: SPTA1 is the most common mutant gene in patients with HE.

Abstract
Objective: To investigate the effect of on-demand glucocorticoid strategy on the occurrence and outcome of porcine anti-lymphocyte globulin (p-ALG) -associated serum sickness in aplastic anemia (AA) . Methods: The data of AA patients who received in the Anemia Diagnosis and Treatment Center of Haematology Hospital, CAMS & PUMC from January 2019 to January 2022 were collected. Among them, 35 patients were enrolled in the on-demand group, with the glucocorticoid strategy adjusted based on the occurrence and severity of serum sickness; 105 patients were recruited in the usual group by matching the age and disease diagnosis according to 1∶3 ratio in patients who received a conventional glucocorticoid strategy in the same period. The incidences, clinical manifestations, treatment outcomes of serum sickness, and glucocorticoid dosage between the two groups were analyzed. Results: The incidences of serum sickness in the on-demand group and the usual group were 65.7% and 54.3% (P=0.237) , respectively. The median onset of serum sickness was the same [12 (9, 13) d vs the 12 (10, 13) d, P=0.552], and clinical symptoms and signs, primarily joint, and/or muscle pain, fever, and rash were similar. Severity grades were both dominated by Grades 1-2 (62.8% vs 51.4%) , with only a few Grade 3 (2.9% vs 2.9%) , and no Grades 4-5. No significant difference in the serum sickness distribution (P=0.530) . The median duration of serum sickness was the same [5 (3, 7) d vs 5 (3, 6) d, P=0.529], and all patients were completely cured after glucocorticoid therapy. In patients without serum sickness, the average dosage of prophylactic glucocorticoid per patient in the usual group was (469.48 ±193.57) mg (0 in the on-demand group) . When compared to the usual group, the average therapeutic glucocorticoid dosage per patient in the on-demand group was significantly lower [ (125.91±77.70) mg vs (653.90±285.56) mg, P<0.001]. Conclusions: In comparison to the usual glucocorticoid strategy, the on-demand treatment strategy could significantly reduce glucocorticoid dosage without increasing the incidence of serum sickness; in addition, the duration of serum sickness and the incidence of above Grade 2-serum sickness were similar.

Abstract
Objective: To analyze the diagnostic value of cell-free plasma metagenomic next-generation sequencing (mNGS) pathogen identification for severe aplastic anemia (SAA) bloodstream infection. Methods: From February 2021 to February 2022, mNGS and conventional detection methods (blood culture, etc.) were used to detect 33 samples from 29 consecutive AA patients admitted to the Anemia Diagnosis and Treatment Center of the Hematology Hospital of the Chinese Academy of Medical Sciences to assess the diagnostic consistency of mNGS and conventional detection, as well as the impact on clinical treatment benefits and clinical accuracy. Results: ①Among the 33 samples evaluated by mNGS and conventional detection methods, 25 cases (75.76%) carried potential pathogenic microorganisms. A total of 72 pathogenic microorganisms were identified from all cases, of which 65 (90.28%) were detected only by mNGS. ②All 33 cases were evaluated for diagnostic consistency, of which 2 cases (6.06%) were Composite, 18 cases (54.55%) were mNGS only, 2 cases (6.06%) were Conventional method only, 1 case (3.03%) was both common compliances (mNGS/Conventional testing) , and 10 cases (30.3%) were completely non-conforming (None) . ③All 33 cases were evaluated for clinical treatment benefit. Among them, 8 cases (24.24%) received Initiation of targeted treatment, 1 case (3.03%) received Treatment de-escalation, 13 cases (39.39%) received Confirmation, and the remaining 11 cases (33.33%) received No clinical benefit. ④ The sensitivity of 80.77%, specificity of 70.00%, positive predictive value of 63.64%, negative predictive value of 84.85%, positive likelihood ratio of 2.692, and negative likelihood ratio of 0.275 distinguished mNGS from conventional detection methods (21/12 vs 5/28, P<0.001) . Conclusion: mNGS can not only contribute to accurately diagnosing bloodstream infection in patients with aplastic anemia, but can also help to guide accurate anti-infection treatment, and the clinical accuracy is high.

Abstract
Background The Proteasome (PSM) is a large multi-catalytic protease complex consisting of a 20S core particle and a 19S regulatory particle whose main function is to accept and degrade ubiquitinated substrates, are now considered as one of the potential regulators of tumor proliferation, and stemness maintenance. However, to date, studies on the relationship between PSM and hepatocellular carcinoma (HCC) are limited. Methods This study used a bioinformatics approach combining validation experiments to investigate the biological mechanisms that may be related with PSM. A series of experiments in vivo and in vitro were performed to explore the function of the 26S proteasome non-ATPase regulatory subunit 13 (PSMD13) in HCC. Results HCC patients can be divided into two clusters. Cluster 1 (C1) patients having a significantly worse prognosis than Cluster (C2). Two subtypes had significant differences in proliferation-related signaling. In particular, the frequency of TP53 mutation was significantly higher in C1 than in C2. In addition, PSM-associated genes were highly consistent with the expression of DNA repair-related signatures, suggesting a potential link between PSM and genomic instability. We also found that downregulation of PSMD13 expression significantly inhibited stemness of tumor cells and impaired the Epithelial mesenchymal transition (EMT) process. Finally, the correlation between the PSMD13 and Ki67 was found to be strong. Conclusion PSM is a valid predictor of prognosis and therapeutic response in patients with HCC disease. Furthermore, PSMD13 may be a potential therapeutic target.

Abstract
poorly cohesive (PC) gastric cancer (GC) (PC-GC) is a distinct histological subtype of GC and is defined as a tumor consisting of isolated or small clusters of tumor cells with poorly differentiated and metastatic characteristics. According to multiple studies, PC-GC is intrinsically heterogeneous, with mesenchymal variants being the most aggressive. However, to date, the molecular mechanisms associated with PC-GC are still not fully understood. This study investigated the role of the USP51/ZEB1/ACTA2 axis in promoting GC metastasis. Single-cell sequencing revealed that E-box binding homeobox 1 (ZEB1) expression was significantly increased in a subpopulation of low-adherent cells and was an independent prognostic factor in GC patients. Furthermore, the bulk transcriptome analysis revealed a significant positive correlation between Ubiquitin Specific Peptidase 51 (USP51), ZEB1, and Actin Alpha 2 (ACTA2), and our data further confirmed that all three were highly co-localized in PC-GC tissues. According to the findings of in vitro and in vivo experiments, USP51 was able to maintain ZEB1 expression to promote ACTA2 transcription, thereby activating the mesenchymal phenotype of GC cells and promoting tumor metastasis. Moreover, USP51 could recruit and activate stromal cells, including M2-like macrophages and fibroblasts, through cancer cells. Clinical data suggested that overexpression of USP51 predicts that patients have difficulty benefiting from immunotherapy and is associated with immune-exclusion tumor characteristics. Collectively, the findings of this study shed light on a key mechanism by which elevated USP51 expression induces Epithelial-mesenchymal transition (EMT) in GC cells, hence facilitating GC cell proliferation, survival, and dissemination. In this view, USP51/ZEB1/ACTA2 may serve as a candidate therapeutic target against GC metastasis.

Abstract
Background The incidence of cutaneous melanoma continues to rise rapidly and has an extremely poor prognosis. Immunotherapy strategies are the most effective approach for patients who have developed metastases, but not all cases have been successful due to the complex and variable mechanisms of melanoma response to immune checkpoint inhibition. Methods We synthesized collagen-coding gene expression data (second-generation and single-cell sequencing) from public Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases. Bioinformatics analysis was performed using R software and several database resources such as Metascape database, Gene Set Cancer Analysis (GSCA) database, and Cytoscape software, etc., to investigate the biological mechanisms that may be related with collagens. Immunofluorescence and immunohistochemical staining were used to validate the expression and localization of Nidogen-2 (NID2). Results Melanoma patients can be divided into two collagen clusters. Patients with high collagen levels (C1) had a shorter survival than those with low collagen levels (C2) and were less likely to benefit from immunotherapy. We demonstrated that NID2 is a potential key factor in the collagen phenotype, is involved in fibroblast activation in melanoma, and forms a barrier to limit the proximity of CD8+ T cells to tumor cells. Conclusion We clarified the adverse effects of collagen on melanoma patients and identified NID2 as a potential therapeutic target.

Abstract
Technical Specifications for Occupational Health Surveillance (GBZ 188-2014) is an important basis for judging suspected occupational diseases and occupational contraindications. There are crossing over or overlap between occupational contraindications and diagnostic criteria of poisoning damage. Occupational contraindications have different meanings with the degree and range of common diseases or symptoms and the frequency of physical examination during employment conflicts with the current standard. Based on the practice of occupational health examination in a large population, the present study analyzed relevant articles and put forward some suggestions for revision, in combination with clinical medicine, occupational health standards, and diagnostic standards of occupational diseases. The modification could provide a reference for the revision of Technical Specifications for Occupational Health Surveillance and the practice of occupational health examination.

Abstract
Background Current evidence suggests that the hypoxic tumor microenvironment further aggravates tumor progression, leading to poor therapeutic outcomes. There is as yet no biomarker capable of evaluating the hypoxic state of the tumor. The cytochrome c oxidase (COX) subunit is crucial to the mitochondrial respiratory chain. Methods We investigated the potential oncogenic role of COX subunit 4 isoform 2 gene (COX4I2) in colorectal cancer (CRC) by least absolute shrinkage and selection operator (LASSO) and COX regression analysis to examine whether COX4I2 overexpression can predict colorectal cancer (CRC) prognosis. The association of COX4I2 levels with clinical features and its biological actions were evaluated both in vitro and in vivo. Results Our analysis showed that elevated COX4I2 levels were correlated with poor clinical outcomes. We also observed that that COX4I2 may be involved in epithelial-mesenchymal transition, activation of cancer-related fibroblasts and angiogenesis in relation to fibroblast growth factor 1. Conclusions The COX4I2 level may be a predictor of outcome in CRC and may represent a novel target for treatment development. Graphical Abstract ![]()

Abstract
Objective: To investigate the effects of exposure to ambient fine particulate matter-bound polycyclic aromatic hydrocarbons on blood coagulation in adults. Methods: A total of 73 adult volunteers were recruited in a cohort study and had four clinical visits from November 2014 to January 2016. Blood samples were obtained and used to measure biomarkers of blood thrombogenicity, including soluble CD40 Ligand (sCD40L), soluble P-selection (sCD62P) and Fibrinogen (FIB). White blood cell (WBC), 8-Hydroxy-2'-Deoxyguanosine (8-OHdG), matrix metalloproteinase-2 (MMP-2) and HDL cholesterol efflux capacity (HDL-CEC) were also determined. Daily concentrations of ambient fine particulate matter-bound polycyclic aromatic hydrocarbons (PAHs) were measured throughout the study period, and positive matrix factorization (PMF) approach was used to identity PAHs sources. Linear mixed-effect models including single-pollutant model, two-pollutant model and stratification analysis were constructed to estimate the effects of exposure to ambient fine particulate matter-bound PAHs on blood thrombogenicity in adults after adjusting for potential confounders. Results: The mean age of participants was (23.3±5.4) years. During the study period, the median level of PM2.5-bound PAHs was (55.29±74.99) ng/m3. Six sources of PM2.5-bound PAHs were identified by PMF, with traffic sources contributing more than 50%. The linear mixed-effect model showed that PAHs exposure had a significant effect on elevated blood thrombogenicity. Significant elevations in sCD40L, sCD62P and FIB associated with per IQR increase (60.33 ng/m3) in exposure to PAHs were 14.36% (95%CI:6.94%-22.28%), 9.33% (95%CI: 1.71%-17.51%) and 2.07% (95%CI:0.44%-2.07%) at prior 5 days, respectively. Blood thrombogenicity levels were significantly and positively correlated with source-specific PAHs, especially gasoline vehicle emissions, diesel vehicle emission and coal burning at prior 1 or 5 days. Stronger associations between PAHs and increased blood thrombogenicity were found in participants with high plaque vulnerability, reduced HDL function, and high levels of inflammation and oxidative stress. Conclusion: Acute exposure to ambient fine particulate matter-bound PAHs, especially PAHs from traffic sources may promote blood thrombogenicity in adults, and PAHs have stronger effects on participants with reduced vascular function and high levels of inflammation and oxidative stress.

Abstract
Background As one of the most immunogenic malignancies, skin cutaneous melanoma (SKCM) is mainly characterized by a high prevalence in immune-compromised patients and a brisk lymphocyte infiltration in the tumor microenvironment (TME). However, to date, studies on deubiquitination in SKCM are still very limited. Methods Public data with regard to this study in SKCM patients were acquired from The Cancer Genome Atlas (TCGA) and the Gene-Expression Omnibus (GEO) databases. We stratified TCGA-SKCM cases using consensus clustering and identified independent prognostic factors in deubiquitinating enzymes encoding genes (DECGs) by LASSO-Cox analysis. USP35 transcriptome level was examined using public data and validated by Immunohistochemical (IHC) staining at the protein level. Enrichment analysis was used to explore the potential functions of USP35, and the TISCH database, providing further evidence at the single-cell level. The CIBERSORT algorithm was used to assess the relationship between USP35 and the immune microenvironment, and IHC was used to further evaluate the relationship between USP35 and immunotherapy response. Finally, we used the cBioPortal and the Methsurv database to analyze the significance of genomic alterations of USP35 in melanoma. Results Our results showed that DECGs can be effectively used to stratify SKCM patients, suggesting their potential significance in the development of SKCM. Furthermore, USP35 overexpression was significantly associated with an unfavorable prognosis. We further revealed that USP35 may be involved in the activation of TORC1 signaling. Most importantly, USP35 was found to be significantly associated with an immunosuppressive TME, both in terms of negative correlation with the abundance of infiltrating CD8+ T cells and in terms of the fact that patients with high USP35 expression may benefit less from immunotherapy than those with low USP35 expression. Conclusion Deubiquitinating enzymes are of great importance in the diagnosis and treatment of SKCM, and USP35 is an extremely promising target for immunotherapy.

Abstract
Objective: To reassess the predictors for response at 6 months in patients with severe or very severe aplastic anemia (SAA/VSAA) who failed to respond to immunosuppressive therapy (IST) at 3 months. Methods: We retrospectively analyzed the clinical data of 173 patients with SAA/VSAA from 2017 to 2018 who received IST and were classified as nonresponders at 3 months. Univariate and multivariate logistic regression analysis were used to evaluate factors that could predict the response at 6 months. Results: Univariate analysis showed that the 3-month hemoglobin (HGB) level (P=0.017) , platelet (PLT) level (P=0.005) , absolute reticulocyte count (ARC) (P<0.001) , trough cyclosporine concentration (CsA-C0) (P=0.042) , soluble transferrin receptor (sTfR) level (P=0.003) , improved value of reticulocyte count (ARC(△)) (P<0.001) , and improved value of soluble transferrin receptor (sTfR(△)) level (P<0.001) were related to the 6-month response. The results of the multivariate analysis showed that the PLT level (P=0.020) and ARC(△) (P<0.001) were independent prognostic factors for response at 6 months. If the ARC(△) was less than 6.9×10(9)/L, the 6-month hematological response rate was low, regardless of the patient's PLT count. Survival analysis showed that both the 3-year overall survival (OS) [ (80.1±3.9) % vs (97.6±2.6) %, P=0.002] and 3-year event-free survival (EFS) [ (31.4±4.5) % vs (86.5±5.3) %, P<0.001] of the nonresponders at 6 months were significantly lower than those of the response group. Conclusion: Residual hematopoietic indicators at 3 months after IST are prognostic parameters. The improved value of the reticulocyte count could reflect whether the bone marrow hematopoiesis is recovering and the degree of recovery. A second treatment could be performed sooner for patients with a very low ARC(△).

Abstract
Purpose The identification of biomarkers and effective therapeutic targets for gastric cancer (GC), the most common cause of cancer-related deaths around the world, is currently a major focus in research. Here, we examined the utility of LHFPL6 as a prognostic biomarker and therapeutic target for GC. Methods We explored the clinical relevance, function, and molecular role of LHFPL6 in GC using the MethSurv, cBioPortal, TIMER, Gene Expression Profiling Interactive Analysis, ONCOMINE, MEXPRESS, and EWAS Atlas databases. The GSE118919, GSE29272, and GSE13861 datasets were used for differential expression analysis. Using The Cancer Genome Atlas, we developed a Cox regression model and assessed the clinical significance of LHFPLs. In addition, we used the “CIBERSORT” algorithm to make reliable immune infiltration estimations. Western blot and immunohistochemistry were used to examine protein expression. Cell migration and invasion were assessed using transwell experiments. THP-1-derived macrophages and GC cells were co-cultured in order to model tumor–macrophage interactions in vitro. The levels of CD206 and CD163 were measured using immunofluorescence assays. The results were visualized with the “ggplot2” and “circlize” packages. Results Our results showed that in GC, LHFPL6 overexpression was significantly associated with a poor prognosis. Our findings also suggested that LHFPL6 may be involved in the activation of the epithelial–mesenchymal transition. Furthermore, LHFPL6 expression showed a positive correlation with the abundance of M2 macrophages, which are potent immunosuppressors. Conclusion LHFPL6 could be a prognostic biomarker and therapeutic target for GC.

Abstract
The identification of biomarkers and effective therapeutic targets for gastric cancer (GC), the most common cause of cancer-related deaths around the world, is currently a major focus area in research. Here, we examined the utility of Neuronal Regeneration Related Protein (NREP) as a prognostic biomarker and therapeutic target for GC. We assessed the clinical relevance, function, and molecular role of NREP in GC using bioinformatics analysis and experimental validation. Our results showed that in GC, NREP overexpression was significantly associated with a poor prognosis. Our findings also suggested that NREP may be involved in the activation of cancer-associated fibroblasts and the epithelial-mesenchymal transition (EMT), with transforming growth factor β1 mediating both processes. In addition, NREP expression showed a positive correlation with the abundance of M2 macrophages, which are potent immunosuppressors. Together, these results indicate that NREP is overexpressed in GC and affects GC prognosis. Thus, NREP could be a prognostic biomarker and therapeutic target for GC.

Abstract
Purpose Gastric cancer (GC) is a common type of cancer worldwide. It can relapse and metastasize even after standard treatment; therefore, it has a poor prognosis. Moreover, sensitive biomarkers for prognosis prediction in GC are lacking. In this study, using a bioinformatics approach, we aimed to examine the value of DAZ Interacting Protein 1 (DZIP1) as a prognostic predictor and therapeutic target in GC. Methods We explored the clinical relevance, function, and molecular role of DZIP1 in GC using MethSurv, cBioPortal, TIMER, Gene Expression Profiling Interactive Analysis, IMEx, ONCOMINE, MEXPRESS, and EWAS Atlas databases. The GSE118919 dataset was used to plot receiver operating characteristic curves. Using The Cancer Genome Atlas, we developed a Cox regression model and assessed the clinical significance of DZIPs. In addition, we used the "xCELL" algorithm to make reliable immune infiltration estimations. Western blot and immunohistochemistry were used to examine protein expression. The results were visualized with the 'ggplot2' and "circlize" packages. Results In GC patients, DZIP1 was over-expressed at both the mRNA and protein levels. High levels of DZIP1 were found to be associated with poor survival in patients with GC. Our results indicated that DZIP1 could be involved in multiple cancer-related pathways such as the PI3K-Akt signaling pathway, WNT signaling pathway, and RAS signaling pathway, and its expression was correlated with the infiltration of activated myeloid dendritic cells, naive CD4+ T cells, and naive CD8+ T cells. Furthermore, we found that mutations in DZIP1 were correlated with a good prognosis in GC patients. Finally, we demonstrated a correlation between hypomethylation of the DZIP1 gene promoter and a poor prognosis in GC. Conclusion This study is the first to demonstrate a significant correlation between high levels of DZIP1 and a poor prognosis in GC patients. Our results clarify multiple potential mechanisms that could contribute to this correlation and may thus provide novel insights into the clinical diagnosis and treatment of GC.

Abstract
Purpose Follistatin-related gene 3 (FSTL3), an established oncogene, can modulate target gene expression via members of the transforming growth factor β (TGF-β) superfamily. The present study was conducted to evaluate the expression of FSTL3 in gastric cancer (GC) and to determine its prognostic significance. We also evaluated the possible mechanisms involved in the oncogenic role of FSTL3 in gastric carcinogenesis and development. Methods We obtained data from the Human Protein Atlas, MethSurv, cBioPortal, UALCAN, TIMER, GEPIA, STRING, GeneMANIA, ONCOMINE, and MEXPRESS databases and examined it using R software. RNAi was used to establish stable FSTL3-knockdown (shFSTL3) and overexpression (OE) cell strains. Western blot; enzyme-linked immunosorbent (ELISA); and immunohistochemical (ICH), immunofluorescence, and phalloidin staining were used for examining protein expression. Cell invasion and migration were determined using transwell and scratch-wound assays. After tumor-associated macrophage (TAM) generation, co-culturing of cancer cells with TAMs was performed to confirm the relationship between FSTL3 and TAMs. Results In GC patients, FSTL3 mRNA and protein levels were upregulated. FSTL3 expression was significantly linked to cancer stage as well as to pathological tumor grade in GC. Moreover, a high expression of FSTL3 was associated with a dismal survival duration in patients with GC. Furthermore, functional enrichment analysis demonstrated that FSTL3 overexpression could activate epithelial-mesenchymal transition (EMT) by promoting F-actin expression and BMP/SMAD signaling. Finally, immunofluorescence staining confirmed that the overexpression of FSTL3 promoted the proliferation of M2 TAMs. Conclusion Taken together, our findings suggest that FSTL3 may be involved in GC progression via the promotion of BMP/SMAD signaling-mediated EMT and M2 macrophage activation.

Abstract
Gastric cancer (GC) is one of the most common causes of cancer-related deaths worldwide and the identification of additional therapeutic targets and biomarkers has become vital. The A1-chimaerin (CHN1) gene encodes a ras-related protein that can be activated or inactivated by binding to GTP or GDP. The present study aimed to assess the expression of CHN1 in GC tissue and cells, to explore its relationship with GC progression, and to discover the potential mechanisms underlying these associations. The ONCOMINE database and The Cancer Genome Atlas (TCGA) were used to determine the transcriptional levels of CHN1 in GC. Western blot and immunohistochemistry were used for detecting protein expression. Correlations between CHN1 levels and the clinical outcomes of GC patients were examined using Kaplan–Meier and Cox regression analyses. Moreover, the CIBERSORT algorithm was used to estimate immune cell infiltration. In GC patients, CHN1 transcription and CHN1 protein expression were upregulated, and a high expression of CHN1 was remarkably linked to poor survival in GC patients. CHN1 expression was associated with immune infiltrates and this gene showed potential involvement in multiple cancer-related pathways. Furthermore, the expression of CHN1 was correlated with the immunotherapeutic response. Finally, our results indicated that the pro-carcinogenic role of CHN1 may involve DNA methylation. To our knowledge, this is the first report characterizing CHN1 expression in GC. Our results show that high CHN1 levels could be used as a clinical biomarker for poor prognosis and that CHN1 inhibitors may have potential as anti-cancer drugs.

Abstract
Objective: To understand the effectiveness and safety sofosbuvir/velpatasvir (SOF/VEL) combination ±ribavirin in the treatment of chronic hepatitis C virus (HCV) infection in China. Methods: A total of 96 Chinese adults with chronic HCV infection who were treated with SOF/VEL combination ± ribavirin for 12 weeks between July 2018 and February 2020 were selected. HCV RNA, routine blood test, liver, kidney and coagulation function, abdominal Color Doppler ultrasound or CT and liver stiffness were detected at baseline, 4 weeks of treatment, end of treatment and 12 weeks of follow-up. Adverse events and laboratory abnormalities during the treatment were recorded. A t-test was used to compare the measurement data between the two groups, and the analysis of variance was used for multiple group comparison. Results: A total of 93 cases (96.9%) achieved sustained virological response (SVR12), of which 3 cases had relapsed. 88 cases (91.7%, 88/96) had achieved rapid virological response (RVR). 96 cases (100%) had achieved virological response by the end of treatment (EOT). In patients with decompensated liver cirrhosis, the average baseline Child-Pugh score and Model for End-Stage Liver Disease score was 7.4±1.0, and 11.4±1.7, respectively. Among them, 12 cases of the SOF/VEL combined with RBV treatment had achieved SVR12 (100%) at 12 weeks, while only 3 of the 5 cases of single-tablet regimen of SOF/VEL had achieved SVR12 (60%). There was no significant difference between creatinine levels and baseline during or 12 weeks after treatment. The incidence of adverse events in patients with chronic hepatitis C and compensated cirrhosis was 6.3% (5/79), while that in patients with decompensated cirrhosis was 35.3% (6/17). The most common adverse events were hyperbilirubinemia, fatigue and anemia. There were no serious adverse events, deaths or discontinuation of treatment due to adverse events. Conclusion: SOF/VEL combination ± ribavirin in the treatment of various common genotypes of chronic hepatitis C, compensated cirrhosis, decompensated cirrhosis and hepatocellular carcinoma has higher SVR12 in China, and the tolerance and safety are good.

Abstract
Objective: To investigate the clinical effect of static staple in the treatment of metatarsal neck fracture. Methods: The clinical data of 34 patients with the 2(nd) to 5(th) metatarsal neck fracture admitted to the Department of Orthopaedic Surgery, Tianjin Fifth Central Hospital from January 2017 to December 2018 were retrospectively analyzed.Seventeen patients were treated with static staple and 17 with retrograde Kirschner wire.In solustaple group, there were 11 males, 6 females, aged 34.6 years (range: 21 to 50 years), 10 cases on the right side, 7 cases on the left side.In retrograde Kirschner wire group, there were 12 males and 5 females, aged 36.2 years (range: 23 to 53 years), 9 on the right and 8 on the left.The fracture healing time was recorded and the postoperative complications were counted.The American Orthopedic Foot and Ankle Society Score (AOFAS) forefoot score, visual analogue scale (VAS), and the active flexion and extension range of metatarsophalangeal joints were measured to compare the clinical efficacy of the two groups.The data were compaired by t test, non-parametric or χ(2) test. Results: All patients were followed up for 14.2 months (range: 12 to 17 months).All the fractures were healed and there was no statistically significant difference between solustaple group and retrograde Kirschner wire group in fracture healing time ((11.2±2.1) week vs.(11.5±3.1) week, t=0.030, P=0.743).There was no statistically significant difference between VAS (1.00 (1.00) vs.1.00 (1.50) M(Q(R)), Z=-0.443, P=0.658) and AOFAS scores(90.9±5.3 vs. 88.6±6.1, t=1.174, P=0.249) at the last follow-up. The difference in active dorsiflexion((35.1±4.3)° vs.(31.2±6.4)°, t=2.055, P=0.048) and flexion range of motion ((34.7±4.5)° vs. (30.2±5.3)°, t=2.681, P=0.011) between the two groups was statistically significant. One case of open fracture in the Solustaple group had local skin necrosis, and three patients had metatarsal pain after weight-bearing walking. Four patients in the retrograde Kirschner wire group developed metatarsalgia after weight-bearing walking, and two patients developed mild dorsal extension contracture and joint pain. Conclusions: The treatment of the 2(nd) to 5(th) metatarsal neck fracture by static staple is minimally invasive and firmly fixed. It can effectively reduce the complications of tendon and joint adhesion, and is beneficial to the fracture healing and joint function recovery.

Abstract
Objective: To evaluate the efficacy and safety of iron supplement in patients who have paroxysmal nocturnal hemoglobinuria (PNH) with iron deficiency. Methods: We performed analyses on the clinical data of 48 patients who accepted oral and/or intravenous iron treatment. Forty-eight consecutive PNH patients with iron deficiency who visited our hospital between November 2011 and August 2018 were enrolled in the study. Results: Total 30 patients received oral iron; 18 patients received intravenous iron supplements, including 6 who did not respond to oral iron. The median PNH clone size was 90.2% (38.5%-99.9%) in the granulocytes and 69.7% (27.6%-98.1%) in the red blood cells. The response rate was 56% (20/36) in patients who received oral iron, and the hemoglobin concentration increased 21 (10-52) g/L compared to that at baseline. Sixteen out of eighteen (89%) patients responded to intravenous iron; 6 patients who did not respond to oral iron received intravenous iron, and the hemoglobin level of 5 patients increased. Patients exhibited increased LDH levels and deepen urine after iron supplementation; however, no severe adverse events, such as thrombosis and iron-related adverse effects, were noted. Conclusion: Iron treatment is safe and effective in increasing the hemoglobin level in PNH patients with iron deficiency; those who did not respond to oral iron could benefit from intravenous iron supplement.

Abstract
As an emerging environmental pollutant, microplastics have attracted more and more attention for its influence on the ecological environment and human health. Due to its wide range of usage and production, difficult degradation and other characteristics, as well as the continuous and substantial increase in the use of plastic products, the number of plastic fragments in the environment continues to increase, which leads to the accumulation of microplastics in the environment and organisms, spread through the food chain, and ultimately poses a threat to human health. At the same time, in the plastic production, synthetic textile, and other industries, the incidence of workers related occupational diseases greatly increased. In this paper, the concept, classification, source, impact on biological and human health of microplastics are summarized, and propose solutions on the current situation of microplastics pollution in China, we hope this review could provide effective reference for further carry out risk assessment of microplastics pollution on human health and formulate legislation to control microplastics pollution.

Abstract
With potent immunomodulatory activities, mesenchymal stem cells (MSCs) have the potential to be a beneficial treatment option for diseases with aberrant immune responses such as systemic lupus erythematosus (SLE). However, the underlying mechanisms remain largely unknown. Here, we used NZBWF1 mice as a SLE animal model to examine immunomodulation of MSCs as well as to assess the role of Toll-like receptor signalling in this circumstance. We found that mice receiving MSCs had a significant decrease in severity of proteinuria at 20 and 22 weeks of age (p = 0.009 and p = 0.022, respectively). Serum anti-dsDNA levels were significantly lower compared with the control group (p = 0.016 and p = 0.036, respectively). C3 and C4 levels were significantly higher at 22 weeks of age (p = 0.046 and p = 0.016, respectively). Altered expression of inflammation-associated cytokine profiles in the serum was also noted in mice receiving MSCs. Down-regulation of myeloid differentiation factor 88 (MyD88)-nuclear factor-κB (NF-κB) signalling in the liver was demonstrated by quantitative polymerase chain reaction, ELISA and Western blotting. In addition to demonstrating the beneficial effects of MSC treatment in NZBWF1 mice, our study provided the first evidence for the association of MyD88-NF-κB signalling and MSC-mediated immunomodulation in this disease.

Abstract
Objective: To detect the red blood cell lifespan in patients with polycythemia vera (PV), and explore the influencing factors. Methods: From February 2017 to December 2018, 27 patients with PV at Blood Diseases Hospital, Chinese Academy of Medical Science and 18 normal controls were recruited. Red blood cell lifespan was detected by endogenous carbon monoxide (CO) breath test. The related factors were analyzed. Results: The average red blood cell lifespan of 27 PV patients was 80 (range, 35-120) days (d), which was significantly shorter than that of the normal controls [110.5(69-166) d, P<0.05], namely 35.3 d shorter. The red blood cell lifespan of ten newly diagnosed patients and 17 patients who were treated with hydroxyurea and/or interferon were 98 (35-117) d and 69 (45-120) d, respectively, which were both shorter than that of the normal control (P=0.010, 0.000). Correlation analysis showed that red blood cell lifespan of patients with newly diagnosed PV was associated with JAK2 mutation allele burden (r=0.900, P=0.037), peripheral blood lymphocyte count (r=-0.742, P=0.014) and the level of serum vitamin B(12) (r=-0.821, P=0.023). Conclusion: The lifespan of red blood cells in patients with PV is about one-third shorter than normal, and is related to JAK2 mutation allele burden, absolute lymphocyte count, and serum vitamin B(12) level.

Abstract
Abstract
Introduction
Clinical data repositories (CDR) including electronic health record (EHR) data have great potential for outcome prediction and risk modeling. However, most CDRs were only used for data displaying, and using data from CDR for outcome prediction often requires careful study design and sophisticated modeling techniques before a hypothesis can be tested.
Purpose
We built a prediction tool integrated with CDR based on pattern discovery aiming to bridge the above gap and demonstrated a case study on contrast related acute kidney injury (AKI) with the system.
Methods
A cardiovascular CDR integrated with multiple hospital informatics systems was established. For the case study on AKI, we included patients undergoing cardiac catheterization from January 13, 2015 to April 27, 2017, excluding those with dialysis, end-stage renal disease, renal transplant, and missing pre- or post-procedural creatinine. To handle missing data, a prior-history-note composer was designed to fill in structured data of 14 diseases related to cardiovascular problem. Crucial data such as ejective fraction was extracted from the structured reports. AKI was defined according to Acute Kidney Injury Network by increase of serum creatinine from most recent baseline to the post-procedure 7-day peak. To build predictive modeling, we selected 17 variables covered in existing AKI models. Pattern discovery was recently developed as an interpretable predictive model which works on incomplete noisy data. In this study, we developed a pattern discovery based visual analytics tool, and trained it on 70% data up to August 2016 with three interactive knowledge incorporation modes to develop 3 models: 1) pure data-driven, 2) domain knowledge, and 3) clinician-interactive. In last two modes, a physician using the visual analytics could change the variables and further refine the model, respectively. We tested and compared it with other models on the 30% consecutive patients dated afterwards, which is shown in Figure 1.
Results
Among 2,560 patients in the final dataset with 17 pre-procedure variables derived from CDR data, 169 (7.3%) had AKI. We measured 4 existing models, whose areas under curves (AUCs) of receiver operating characteristics curve for the test set were 0.70 (Mehran's), 0.72 (Chen's), 0.67 (Gao's) and 0.62 (AGEF), respectively. A pure data-driven machine learning method achieves AUC of 0.72 (Easy Ensemble). The AUCs of our 3 models are 0.77, 0.80, 0.82, respectively, with the last being top where physician knowledge is incorporated.
Demo and demonstration
Conclusions
We developed a novel pattern-discovery-based outcome prediction tool integrated with CDR and purely using EHR data. On the case of predicting contrast related AKI, the tool showed user-friendliness by physicians, and demonstrated a competitive performance in comparison with the state-of-the-art models.

Abstract
Objective: To investigate the effect of perioperative fluid therapy on early postoperative pulmonary complication (PPC) after orthotopic liver transplantation (OLT). Methods: The clinical data of 132 patients who underwent OLT in the First Affiliated Hospital of Xi'an Jiaotong University from April 2016 to December 2017 were analyzed retrospectively. These patients included 96 males and 36 females, aged (47.3±9.6) years (range: 24-69 years). Based on the clinical manifestations, laboratory and imaging findings of patients in ICU and PPC occurrence within 7 days after OLT surgery, the patients were divided into 2 groups: non-PPC group and PPC group. Univariate and multivariate logistic regression analyses were used to evaluate the association between perioperative variables and PPC. The Kaplan-Meier method was used to estimate cumulative survival of recipients with or without PPC within 2-years. Results: During the follow-up, 11 patients (8.3%) died and 72 patients (54.5%) developed PPC after operation. There were 34 cases, 6 cases, 3 cases, 4 cases, 15 cases, 6 cases and 4 cases of only pleural effusion, only pulmonary edema, only pneumonia, pleural effusion with pneumonia, pleural effusion with pulmonary edema, pleural effusion with atelectasis, and pleural effusion with pneumonia and pneumonia in PPC, respectively. Univariate analysis showed that the preoperative factors (model for end-stage liver disease score), the intra-operative factors (duration of surgery, total infusion volume, total blood products) and the postoperative cumulative fluid balance within the first 24 h, 48 h, and 72 h were the prognosis factors of PPC (P<0.05). At least two out of the first three postoperative days with a fluid balance of ≤-500 ml was a protective factor. Using multivariate analysis by Logistic regression, only the red blood units >10 U (OR=3.55, 95% CI: 1.35-9.26, P=0.010) and the cumulative fluid intake >12 L (OR=2.98, 95% CI: 1.14-7.80, P=0.026) within the first 72 h after operation were independent prognosis factors of PPC after OLT. Kaplan-Meier analysis showed that the cumulative survival rate was lower in PPC group than that in non-PPC group (χ(2)=6.590, P=0.01). Conclusion: Massive red blood cell transfusion and the cumulative fluid volume >12 L during perioperative 72 hours are independent prognosis factors of PPC after OLT.

Abstract
The American Joint Committee on Cancer (AJCC) released its 8th edition of cancer staging implemented in early 2018. This study aims to compare anatomic staging (AS) with prognostic staging (PS) based on the updated AJCC 8th edition staging manual. A retrospective single-center analysis of 313 triple-negative breast invasive ductal carcinoma patients who received surgery at department of breast surgery in the Fourth Hospital of Hebei Medical University from 01/2010 -12/2012 was performed. All cases were restaged using the AJCC 8th edition AS and PS system. The 7-year disease-free survival (DFS) and the 7-year overall survival (OS) rates were 76.30% and 78.27%, respectively. Applying the PS system, 277 (88.5%) patients of the AS groups were upstaged to the PS groups, 31 cases with IIIC and 5 cases with IV unchanged (11.5%) and no cases downstaged. Both 7-year DFS and 7-year OS were significantly different in the different AS and PS groups (all, p<0.001). The PS system was found to provide better prognostic information in patients with AS group IIB. A total of 43 patients with AS group IIB were upstaged by PS system, in which 30 patients were +2 upstaged to PS IIIB, and 13 patients were +3 upstaged to PS IIIC. PS IIIB and IIIC from AS IIB had significant differences in 7-year DFS (χ2=5.628, p=0.014) and 7-year OS (χ2=6.037, p=0.018). Both AS and PS systems proposed in the 8th edition of the AJCC breast cancer staging manual had prognostic value in TNBC. Moreover, the PS system predicts clinical outcomes of TNBC patients more accurately than the traditional AS system.

Abstract
Objective: To evaluate the therapeutic efficacy and safety of immunosuppressive therapy (IST) combined with recombinant human thrombopoietin (rhTPO) for severe aplastic anemia (SAA) in pediatric patients. Method: A retrospective case-control study was conducted and the clinical data of 45 pediatric patients with de novo SAA admitted to the Anemia Diagnosis and Treatment Center of Chinese Academy of Medical Sciences & Blood Disease Hospital during the period from December 2009 to December 2014 were analyzed. Among them, 15 patients were treated with the regimen of IST together with rhTPO and 30 patients were given IST treatment only. The variation characteristics of the peripheral blood routine as well as the transfusion of blood products was dynamically observed, and the therapeutic efficacy was assessed respectively after 3, 6 and 12 months after the treatment. In the meantime, adverse effects related to rhTPO application were recorded. Thereafter, the statistics of the two groups were compared by non-parametric rank sum test. Result: Among 45 pediatric patients, there were 26 male and 19 female, and the median age was 11 years (6-14). The number of patients received good hematological response(complete remission (CR) plus good partial response (GPR)) in the combinatory group versus vs. the IST group was 6 vs. 3 patients (χ(2)=3.906, P=0.048) at the 3rd month, 7 vs. 7 patients (χ(2)=1.568, P=0.210) at the 6th month, and 13 vs. 14 patients (χ(2)=6.667, P=0.01) at the 12th month respectively. For those achieved good hematological response at the 3rd month, the amount of platelets transfusion and red blood cells transfusion of the combined group were both less than that of the IST group during the period from the 10th to the 12th weeks (platelets transfusion: 1.4 U vs. 2.9 U, t=-3.523, P=0.002; red blood cells transfusion: 0.8 U vs. 2.6 U, t=-2.392, P=0.026). No serious adverse effect related to rhTPO application was observed in the IST combined with rhTPO group. Conclusion: Application of rhTPO can improve the short-term therapeutic efficacy of IST for pediatric SAA, alleviate transfusion dependence, and has a good safety profile.

Abstract
Objective: To investigate the effect of antiviral therapy on the progression of liver cirrhosis and related predictive factors through a retrospective analysis of patients with compensated hepatitis C cirrhosis. Methods: The patients with compensated hepatitis C cirrhosis who were treated in our hospital from 2004 to 2015 were divided into sustained virologic response (SVR) group, non-SVR (NSVR) group, and untreated group. The baseline features of patients with or without liver cirrhosis were compared to identify the predictive factors for the progression of liver cirrhosis. The changes in platelet count, spleen sizes, Model for End-Stage Liver Disease (MELD) score, Sequential Organ Failure Assessment (SOFA) score, and Child-Turotte-Pugh (CTP) score were analyzed, and the incidence rate of liver cancer was compared between groups. A one-way analysis of variance, the Kruskal-wallis H test, the two-independent-sample t test, the chi-square test, and a multivariate logistic regression analysis were used for data analysis based on data type. Results: A total of 89 patients with compensated liver cirrhosis were enrolled, among whom 42 received the antiviral treatment with interferon and ribavirin (30 were treated with pegylated interferon-α and 12 were treated with ordinary interferon) and 47 did not receive any antiviral therapy. Among the patients who received the antiviral treatment with interferon and ribavirin, 20 achieved SVR and 22 did not achieve SVR. Compared with baseline values, platelet count in the SVR group and the NSVR group was increased by (44.93 ± 32.66)×10(9)/L and (9.73 ± 28.83)×10(9)/L, respectively, and platelet count in the untreated group was reduced by (19.76 ± 54.5)×10(9)/L; the three groups had a significant change in platelet count (F = 14.731, P < 0.001). Spleen size was reduced by 0.91 ± 1.09 cm in the SVR group and increased by 0.20±0.84 cm and 1.11 ± 1.69 cm in the NSVR group and the untreated group, respectively; the three groups had a significant change in spleen size (F = 14.943, P < 0.001). The three groups had no significant changes in MELD, SOFA, and CTP scores (P > 0.05). One patient (5.00%) in the SVR group, 5 (22.73%) in the NSVR group, and 6 (12.77%) in the untreated group progressed to liver cancer (χ (2) = 13.787, P = 0.001). The univariate analysis showed that SVR, HCV RNA, total bilirubin, and albumin were predictive factors for disease progression, and the multiple logistic regression analysis demonstrated that SVR and total bilirubin were predictive factors for disease progression. Conclusion: Interferon combined with ribavirin has a marked clinical effect in the treatment of compensated hepatitis C cirrhosis with good short- and long-term efficacy.

Abstract
Objective: To investigate the respiratory central hypoxia response and its related factors in Han and Uygur patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: One hundred and sixty six OSAHS patients were selected from Jan. 2016 to Dec. 2016 in Department of Respiratory and Critical Care Medicine, Kelamayi Central Hospital, including 69 cases of Han nationality and 97 cases of Uygur nationality. Seventy-three healthy subjects of Uygur nationality were enrolled as the control group. All of them under went sleep monitoring, nocturnal oxygen saturation (SaO(2)), pulmonary function and respiratory central hypoxia response. Results: The 3 groups were matched for age, gender, body mass index(BMI) and apnea-hypopnea index(AHI). The Uygur patients had a higher oxygen desaturation index (ODI4) [(30±22) per hour vs (18±17) per hour ] than Han patients of the same age and BMI. Compared to Han patients, Uygur patients had weaker hypoxic responsiveness [(-0.41±0.23) L·min(-1)·%(-1) vs (-0.36±0.22) L·min(-1)·%(-1,) P<0.05], and the difference still existed after adjusting for AHI [(-0.31±0.21) L·min(-1)·%(-1) vs (-0.41±0.22) L·min(-1)·%(-1,) P<0.05] in mild OSAHS, but this difference was not significant in severe OSAHS. Conclusions: The central hypoxic response in Uygur OSAHS patients was lower than that in Han OSAHS patients and normal controls.

Abstract
Objective: To explore the application value of adaptive statistical iterative reconstruction (ASIR) combined with low tube voltage in three-stage enhanced low-dose scan of liver. Methods: From March 2017 to November 2017, two groups which each group included 50 patients were randomly selected at the Second Affiliated Hospital of Harbin Medical University with different stages of arterial phase, delayed phase and portal vein scanning. GE Discovery CT 750 HD Liver CT Ⅲ was used during enhanced scanning. A total of 100 patients included 56 males and 44 females, aged 27-73 years old and 42 patients with hepatocellular carcinoma, 44 patients with hepatic hemangioma, and 14 patients with other diseases. The arterial and delayed period of group A patients were scanned with a low dose of 100 kV+ASIR, and the portal vein phase was conventional. Dosage scanning was 120 kV+FPP; the arterial and delayed period of group B was normal dose scanning, 120 kV+FPP, and the portal vein phase was low dose scanning, 100 kV+ASIR. At the same time, FBP reconstruction was used for all low-dose scanning phases to obtain low-dose images under normal reconstruction mode. The objective evaluation index of image quality was analyzed by completely randomized design analysis of variance, and Dunnett-t test was used to compare the two groups. For the subjective evaluation part, the rank sum test of multiple groups was used. Results: ASIR combined with low tube voltage enhanced low dose scanning in the third phase of the liver, and the radiation dose decreased by 37% in the low dose group compared with the normal dose group. There was no statistically significant difference between the low dose group (100 kV+ASIR) and the normal dose group (120 kV+FPP) in subjective image quality evaluation (P>0.05); objective evaluation of image quality except for low dose(100 kV+ASIR) portal stage noise slightly worse than conventional dose group (120 kV+FBP) (low dose 10.86±1.98, conventional dose 9.40±2.12, P<0.05), the other indexes in each period were superior or indifferent to the normal dose group. Conclusion: ASIR technique combined with low tube voltage can be used in the third phase of liver enhanced low-dose scanning and the image quality is improved.

Abstract
Objective: To evaluate the results of pars plana vitrectomy (PPV) with peeling of the inner limiting membrane (ILM) in patients with laser-induced macular hole. Methods: The clinical data of 11 patients (12 eyes) with decreased visual acuity due to laser-induced macular hole from January 2014 to December 2017 were retrospectively studied.All patients underwent routine examination, fundus photography and optical coherence tomography (OCT). Patients were observed every two weeks. PPV with ILM peeling was performed when macular hole was enlarged. Closure of macular hole, pre- and post-operation visual acuity were observed. Results: A total of 11 male patients (12 eyes)aged (18±4) years were included in the study.Laser instruments which lead to macular hole consisted of laser toy (3 eye), laser pen (4 eye), laser torch (1 eye) and cosmetic laser instrument (4 eyes). All patients were followed up every two weeks and evaluated by OCT. None of the macular hole was spontaneously closed in this study. All Macular holes were enlarged in 1-3 months of follow-up and underwent PPV with ILM peeling immediately. All of the macular hole with PPV and ILM peeling were completely closed. During follow-up, the best-corrected visual acuity(BCVA) of 10 eyes (10/12) were found to increase above 3 lines and BCVA of 7 eyes(7/12) were found to be more than 0.5. Only 1 eye maintained the same visual acuity after the surgery which might be due to long course, large macular hole diameter (850 μm) and serious retinal pigment epithelium (RPE) damage. Conclusion: Early PPV with ILM peeling for laser induced macular hole might benefit for the closure rate of macular hole and better visual acuity prognosis.

Abstract
Objective: To study the protective effect of Ascorbic acid (AA) on the injury of nickel-exposed mouse embryonic fibroblasts (NIH/3T3) . Methods: A model of damage induced by 50 μg/mL nickel refining dust was established to determine the relative survival rate of cells, superoxide dismutase (SOD) , lactate dehydrogenase (LDH) and glutathione peroxidase. (GSH-Px) activity, hydrogen peroxide (H(2)O(2)) and malondialdehyde (MDA) content, and p53 (wild-type) , Bcl-2 protein expression. To investigate the protective effect of different doses of ascorbic acid (25, 50, 100 mmol/L) on nickel-refined dust-induced NIH/3T3 cell injury. Results: The study showed that ascorbic acid Ⅲ group can make the NIH/3T3 cell survival rate increased significantly; Apoptosis rate was reduced; The vitality of SOD and GSH-Px increased significantly, and the difference was statistically significant (P<0.05) . At the same time, the level of MDA and H(2)O(2) and the activity of extracellular LDH enzyme were significantly reduced, and the difference was statistically significant (P<0.05) . The results showed that nickel refining dust induced cell damage through up-regulation of p53 protein and down-regulation of Bcl-2 protein expression; ascorbic acid interventions, the expression level of Bcl-2 protein in ascorbic acid II and III groups was higher than that of nickel refining dust group, and the difference was statistically significant (P<0.05); The expression level of p53 protein in each dose group of ascorbic acid was lower than that of nickel refined dust group, and the difference was statistically significant (P<0.05). Conclusion: With the increase of concentration of ascorbic acid, oxidative damage levels, antioxidant enzyme levels, reduce cell apoptosis, reduce expression of p53, increased expression of Bcl-2. It showed that ascorbic acid had protective effect on NIH/3T3 cell injury induced by nickel refining dust.

Abstract
Objective: To investigate epidermal growth factor receptor (EGFR) and thymidylate synthase (TS) expression in primary liver cancer, and analyze its clinicopathological features and prognostic significance. Methods: Immunohistochemistry was performed using EnVision method to detect EGFR and TS expression in 41 cases of liver cancer. Correlation coefficient between EGFR and TS was calculated by Spearman method. Fisher's exact probability method or χ(2) test was used to analyze the clinicopathological features of EGFR and TS. Kaplan-Meier method was used to calculate the survival rate of patients in conjunction with the log-rank test.COX proportional hazard regression model was used to analyze the prognostic factors of patients. ROC curve was used to analyze the predictive accuracy of EGFR and TS for prognosis. Results: The positive rates of EGFR and TS in liver cancer tissues were 34.15% and 39.02%, respectively. There was a positive correlation between EGFR and TS expressions, and the difference was statistically significant (P < 0.05). EGFR was associated with tumor size and tissue differentiation (P < 0.05) in HCC patients, whereas TS was associated with tissue differentiation (P < 0.05). There was no significant difference in prognostic effect of EGFR on survival rate (P > 0.05). TS prognostic effect on survival rate was statistically significant (P < 0.05). HR of EGFR was 0.210 with 95% CI, 0.052-0.852, P = 0.029; indicating that the risk of death in patients with negative EGFR was 0.210 times higher than that in patients with positive EGFR. HR of TS was 2.496, with 95% CI, 1.325-4.701, P = 0.005, indicating that the risk of death increased by 2.496 times with the same level of EGFR. The area under the EGFR curve was 0.553 and its approximate reference confidence interval was 95% (0.355, 0.751), indicating that EGFR was a risk factor for death and the area under the TS curve was 0.695, and its approximate reference confidence interval was 95% (0.513, 0.878), indicating that TS was a risk factor for death. Conclusion: EGFR and TS were equally expressed in primary liver cancer, and EGFR and TS expressions were positively correlated. EGFR and TS had an effect on the degree of tissue differentiation in patients with liver cancer. EGFR and TS were risk factors for prognosis, and TS may assist EGFR.
