Abstract
During the investigations of macrofungi resources in Zhejiang Province, China, an interesting wood rot fungus was collected. Based on morphological and molecular phylogenetic studies, it is described as a new species, Anthracophyllum sinense. A. sinense is characterized by its sessile, charcoal black and pleurotoid pileus, sparse lamellae occasionally branching, clavate basidia with long sterigmata [(3-)6-7(-8) μm], and non-heteromorphous cystidia. A. sinense establishes a separate lineage close to A. archeri and A. lateritium in the phylogenetic tree.

Abstract
OBJECTIVE To investigate coronary artery disease (CAD) and its correlation with the ambulatory arterial stiffness index (AASI) in patients with H-type hypertension (essential hypertension combined with hyper-homocysteinemia) and coronary heart disease (CHD). METHODS Patients with essential hypertension and CHD who were undergoing coronary angiography were enrolled. The general clinical data, biochemical indicators, ambulatory blood pressure monitoring results and coronary angiography results of the selected patients were collected, and the AASI and Gensini scores were calculated. According to homocysteine (Hcy) levels, the patients were divided into two groups: a study group and a control group. The differences in general clinical data, biochemical indexes, AASI scores and degree of coronary artery lesions between the two groups were compared. The correlation between the AASI and the Gensini score and the relationship between the AASI and the Gensini score of CAD and various factors were analyzed. RESULTS Compared with the control group, the Hcy level in the study group was significantly increased (8.16 ± 2.33 vs 19.20 ± 2.36, P = .001). The 24-h diastolic blood pressure (DBP) in the study group was significantly lower than that in the control group (76.38 ± 9.33 vs 79.91 ± 9.25, P = .002), and the AASI was significantly higher than in the control group (0.62 ± 0.81 vs 0.420 ± 0.70, P = .001). The number of patients having coronary stenoses with a Gensini score of ≤ 38 was significantly lower in the study group than in the control group (21.3% vs 49.4%, P < .001). The number of patients with a Gensini score of ≥ 51 in the study group was significantly higher than in the control group (22.0% vs 18.8%, P < .001). There was a significant positive correlation between the AASI and the Gensini score in the study group (R = 0.732, P < .001). Hypertension duration (β = 0.168), diabetes history (β = 0.236), 24-h SBP (β = 0.122), 24-h DBP (β = -0.131), low-density lipoprotein cholesterol (β = 0.134) and Hcy (β = 0.233) were the influencing factors for AASI (P < .05). Both Hcy * AASI (β = 0.356) and Hcy × 24-h HR (β = 0.331) had a synergistic effect on the Gensini score (P = .017), with Hcy * AASI having a more significant effect on the Gensini score (P < .001). CONCLUSION The AASI was significantly increased in patients with H-type hypertension and CHD, which was associated with the severity of CAD. Therefore, Hcy levels and the AASI have a synergistic effect when evaluating the severity of CAD in patients with hypertensive CHD.

Abstract
Objective: To explore the relationship between liver iron deposition and steatosis in patients with non-alcoholic fatty liver disease (NAFLD) through MRI. Methods: 163 cases of liver biopsy underwent MRI examination. R2* was used to measure liver iron content. Dixon-based proton density fat fraction (PDFF) was used to measure liver fat content. One-way ANOVA, r-correlation, ROC curve, and others were used to assess the relationship between clinical case data, serological indices, and imaging results in accordance with the pathological results of the liver biopsy. Results: R2* gradually increased as the pathological steatosis grade rose. The R2* that corresponded to no steatosis (< 5%), mild steatosis (14.95%±8.55%), moderate steatosis (46.30%±9.32%), and severe steatosis (73.86%±6.35%) were 27.56±4.40, 31.06±5.95, 38.06±4.80, and 48.10±5.55 (P < 0.001), respectively. There was a positive correlation between R2* and liver steatosis content (r= 0.769, P < 0.05). The area under the ROC curve and cut-off value were 0.88 and 31.77, respectively, and there was no distinct relationship with liver inflammation or fibrosis. Conclusion: R2* can quantitatively and non-invasively evaluate liver iron deposition in patients with NAFLD. A distinct relationship exists between liver steatosis and iron deposition, and iron deposition tends to increase as the steatosis aggravates.

Abstract
Fungi of the order Boletales are extremely important in both ecology and economy, since most of them are ectomycorrhizal fungi, which play vital roles in maintaining forest ecosystems, water and soil protection, vegetation restoration and so on. Although previous studies have shown that this order has a very high species diversity in China, there are few reports on the species diversity of boletes in Jiangxi Province, China. Based on morphological (macroscopic and microscopic morphological characteristics) and phylogenetic analyses (ITS, LSU, and TEF1-α sequences), in this study, the wild boletes in Jiangxi Province were investigated, and five new species are described: Austroboletus albus, Xanthoconium violaceipes, Xanthoconium violaceofuscum, Xerocomus rutilans and Xerocomus subsplendidus. Descriptions and hand drawings of the new species are presented.

Abstract
Gastric cancer (GC) is defined as the primary epithelial malignancy derived from the stomach, and it is a complicated and heterogeneous disease with multiple risk factors. Despite its overall declining trend of incidence and mortality in various countries over the past few decades, GC remains the fifth most common malignancy and the fourth leading cause of cancer-related death globally. Although the global burden of GC has shown a significant downward trend, it remains severe in certain areas, such as Asia. GC ranks third in incidence and mortality among all cancer types in China, and it accounts for nearly 44.0% and 48.6% of new GC cases and GC-related deaths in the world, respectively. The regional differences in GC incidence and mortality are obvious, and annual new cases and deaths are increasing rapidly in some developing regions. Therefore, early preventive and screening strategies for GC are urgently needed. The clinical efficacies of conventional treatments for GC are limited, and the developing understanding of GC pathogenesis has increased the demand for new therapeutic regimens, including immune checkpoint inhibitors, cell immunotherapy and cancer vaccines. The present review describes the epidemiology of GC worldwide, especially in China, summarizes its risk and prognostic factors, and focuses on novel immunotherapies to develop therapeutic strategies for the management of GC patients.

Abstract
Brain networks have significant implications for the understanding of migraine pathophysiology and prognosis. This study aimed to investigate whether large-scale network dysfunction in patients with migraine without aura (MwoA) could predict the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs). Seventy patients with episodic MwoA and 33 healthy controls (HCs) were recruited. Patients were divided into MwoA with effective NSAIDs (M-eNSAIDs) and with ineffective NSAIDs (M-ieNSAIDs). Group-level independent component analysis and functional network connectivity (FNC) analysis were used to extract intrinsic networks and detect dysfunction among these networks. The clinical characteristics and FNC abnormalities were considered as features, and a support vector machine (SVM) model with fivefold cross-validation was applied to distinguish the subjects at an individual level. Dysfunctional connections within seven networks were observed, including default mode network (DMN), executive control network (ECN), salience network (SN), sensorimotor network (SMN), dorsal attention network (DAN), visual network (VN), and auditory network (AN). Compared with M-ieNSAIDs and HCs, patients with M-eNSAIDs displayed reduced DMN-VN and SMN-VN, and enhanced VN-AN connections. Moreover, patients with M-eNSAIDs showed increased FNC patterns within ECN, DAN, and SN, relative to HCs. Higher ECN-SN connections than HCs were revealed in patients with M-ieNSAIDs. The SVM model demonstrated that the area under the curve, sensitivity, and specificity were 0.93, 0.88, and 0.89, respectively. The widespread FNC impairment existing in the modulation of medical treatment suggested FNC disruption as a biomarker for advancing the understanding of neurophysiological mechanisms and improving the decision-making of therapeutic strategy.

Abstract
Objective: To analyze the survival and influencing factors of HIV infections and AIDS cases (HIV/AIDS) aged 15 years and over who had received antiretroviral treatment (ART) for more than 10 years in Henan Province. Methods: In this retrospective cohort study, data of HIV infections and AIDS cases in Henan province were collected from the AIDS Prevention and Control System between January 1, 2002 and December 31, 2020. This study included 20 256 participants alive after 10-year ART with complete baseline and follow-up information, such as demographic characteristics, CD4+T lymphocyte count and viral load. Cox proportional risk regression model was used to analyze influencing factors of HIV/AIDS survival. Results: A total of 20 256 participants were followed up for 82 738.2 person-years, with an average follow-up of 4.1 person-years, of which most cases were blood transmission (85.5%) and married (71.2%). The male to female ratio was 1∶1.06 and the age at 10 years of ART was (51.2±8.7) years old. About 88.5% of HIV/AIDS patients received ART in village/township treatment institutions. Overall, there were 2 030 deaths during this period, among which 1 897 were due to AIDS-related diseases (93.5%) and the case fatality rate was 9.4% (1 897/20 256). Cox proportional risk regression model showed that participants aged 40-54, 55-69, and ≥70 years had a higher risk of death compared to those aged 25-39, with adjusted HRs (95%CI) of 1.57 (1.19-2.08), 3.78 (2.86-4.99), and 6.17 (4.33-8.79), respectively. Participants with the initial CD4+T lymphocyte count about 200-349/μl and<200/μl had a higher risk of death compared to those with initial CD4+T lymphocyte count ≥350/μl, with adjusted HRs (95%CI) of 1.81 (1.61-2.04) and 3.64 (3.20-4.15), respectively. Participants with the initial viral load outcome ≥1 000 copies/ml had a higher risk of death compared to those with the initial viral load outcome<1 000 copies/ml, with adjusted HRs (95%CI) of 1.73 (1.52-1.97). Participants receiving the second-line ART had a lower risk of death compared to those receiving the first-line ART, with adjusted HRs (95%CI) of 0.12 (0.11-0.14). Conclusion: From 2002 to 2020, the survival rate of HIV/AIDS treated with ART for more than 10 years is high in Henan Province. Age, CD4+T lymphocyte count and viral load are influencing factors of HIV/AIDS survival.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Urtica fissa E. Pritz. are important herbs and have been traditionally used as ethnic medicine to treat rheumatism, inflammation, diabetes, and benign prostatic hyperplasia by the Han, Uighur, and other minorities in China, and also as an aphrodisiac in Uighur medicine. AIMS OF THE STUDY To determine the effect and potential mechanism of 3, 4-divanillyltetrahydrofuran (DVTF), one of the main active components isolated from U. fissa on hypogonadism in diabetic mice. MATERIALS AND METHODS The active compound DVTF was extracted and separated from the roots of U. fissa and identified using mass spectrometry and nuclear magnetic resonance spectroscopy. A mouse model of diabetes was established using high fat and sugar diet combined with streptozotocin. In the treatment groups, mice were received different doses of DVTF for 4 weeks. Fasting blood glucose levels, physiological and biochemical indices, and the mating behavior of DM mice were analyzed. Changes in testicular morphology were assessed using light microscopy and transmission electron microscopy. The expression of testosterone synthesis-related signaling proteins was detected using western blotting. Molecular docking was used to determine the binding ability of DVTF to Nur77. RESULTS In diabetic mice, body weight and fasting blood glucose levels decreased. Mating behavior, including mount latency, mount number, and intromission number, was improved following DVTF treatment. Plasma total testosterone, free testosterone, and insulin resistance were positively associated with the recovery of testicular pathological structures in diabetic mice. DVTF treatment increased the expression of Nur77, StAR, and P450scc in the testes of diabetic mice. DVTF and Nur77 formed chemical bonds at five sites. CONCLUSION As one of the main active components of U. fissa, DVTF exert potential therapeutic effects on testicular injury and hypogonadism caused by diabetes through activating the expression of Nur77 and testosterone synthesis related proteins. Our result will provide new insight for the clinical application of Urtica fissa E. Pritz., especially DVTF, as a potential drug candidate in the treatment of hypogonadism in diabetes.

Abstract
The most common histological type of gastric cancer (GC) is gastric adenocarcinoma arising from the gastric epithelium. Less common variants include mesenchymal, lymphoproliferative and neuroendocrine neoplasms. The Lauren scheme classifies GC into intestinal type, diffuse type and mixed type. The WHO classification includes papillary, tubular, mucinous, poorly cohesive and mixed GC. Chronic atrophic gastritis (CAG) and intestinal metaplasia are recommended as common precancerous conditions. No definite precancerous condition of diffuse/poorly/undifferentiated type is recommended. Chronic superficial inflammation and hyperplasia of foveolar cells may be the focus. Presently, the management of early GC and precancerous conditions mainly relies on endoscopy including diagnosis, treatment and surveillance. Management of precancerous conditions promotes the early detection and treatment of early GC, and even prevent the occurrence of GC. In the review, precancerous conditions including CAG, metaplasia, foveolar hyperplasia and gastric hyperplastic polyps derived from the gastric epithelium have been concluded, based on the overview of gastric epithelial histological organization and its renewal.

Abstract
Objective: To analyze the correlation between serum ferritin and steatosis in non-alcoholic fatty liver disease. Methods: Data of 167 cases who underwent liver biopsy in the Affiliated Hospital of Hangzhou Normal University were collected. Hydrogen proton magnetic resonance spectroscopy were performed within one week. The pathological results of liver biopsy were used as the gold standard to analyze the case data, serological indicators, magnetic resonance spectroscopy-proton density fat fraction. Results: Pathological monitoring result showed that the serum ferritin in patients without steatosis, and with mild, moderate and severe steatosis were (206.20 ± 189.83), (286.65 ± 200.80), (326.55 ± 214.71), (391.50 ± 184.93) ng/ml, respectively, P < 0.005. Serum ferritin was correlated to body mass index, PDFF, alanine aminotransferase, gamma glutamyltransferase, low-density lipoprotein, high-density lipoprotein. The area under the receiver operating characteristic curve with ferritin for the diagnosis of non-alcoholic fatty liver disease was 0.716, and the optimal diagnostic threshold was 214.56 ng/ml. The sensitivity and specificity were 80.1%, and 68.8%, respectively. There was no statistically significant difference between the intralobular inflammation, fibrosis, and ferritin. Prussian blue iron staining had no apparent deposition of iron particles. Conclusion: Ferritin has significant positive correlation with the results of pathological and magnetic resonance imaging for liver steatosis. Therefore, it can be used as a non-invasive diagnostic method for liver steatosis evaluation.

Abstract
Chronic inflammation is considered as an important pathophysiologic mechanism of hepatic cirrhosis, which induces hepatocyte injury and activates hepatic stellate cells (HSCs), thus resulting in hepatic fibrosis. Previous studies have reported that cyclooxygenase-2 (COX-2) inhibitor can effectively treat liver fibrosis, while somatostatin (SST) analogues inhibit the activation of HSCs. The present study aimed to investigate the effects of a COX-2 inhibitor, celecoxib, combined with a SST analogue, octreotide, for protection of hepatocytes and prevention of fibrosis in a rat model of hepatic fibrosis. Therefore, a hepatic fibrosis rat model was established following peritoneal injection of thioacetamide (TAA), and the rats were then treated with a combination of celecoxib and octreotide (TAA + C). Immunohistochemistry and western blotting assays were used to assess the expression levels of proteins associated with inflammation, epithelial-mesenchymal transition (EMT), proliferation, apoptosis and autophagy. H&E staining, transmission electron microscopy and scanning electron microscopy were used to evaluate the destruction of hepatocytes. Masson's Trichrome and Sirius Red were used to measure the degree of liver fibrosis. The results demonstrated that, compared with those of the control group, the degree of liver fibrosis and the expression of the intrahepatic inflammation factors were aggravated in the TAA group. Furthermore, the apoptosis rate, EMT and autophagy of hepatocytes were also increased in the TAA group. However, treatment with TAA + C restored the aforementioned increased levels compared with the TAA group. In conclusion, treatment of rats with the combination of celecoxib and octreotide could attenuate the progress of hepatic fibrosis via protection of hepatocytes by reducing apoptosis, EMT and autophagy in hepatocytes.

Abstract
Objective: To analyze the mortality in HIV/AIDS cases aged ≥15 years under antiretroviral treatment (ART) in Henan province from 2002 to 2019, and provide evidence for reducing the mortality rate of HIV/AIDS and AIDS prevention and treatment. Methods: Data of HIV/AIDS cases aged ≥15 years who received ART in Henan from 2002 to 2019 were obtained from "Infectious Disease Surveillance System - Basic Information on AIDS Prevention and Control". In this retrospective study, Cox proportional risk model was used to analyze the influencing factors for HIV/AIDS related deaths. Software SPSS 23.0 was used for statistical analysis. Results: From 2002 to 2019, a total of 72 986 HIV/AIDS cases aged ≥15 years received ART, in whom, 16 634 died during this period. Most of the death cases were aged ≥40 years old (68.5%,11 393/16 634), males (62.6%,10 419/16 634), infected through blood-borne transmission (71.7%,11 927/16 634), and farmers or migrant workers (91.7%,15 249/16 634). Most of the deaths were due to AIDS related diseases (73.7%, 12 261/16 634), and the case fatality rate was 16.8% (12 261/72 986). A total of 34.6% (4 237/12 261) of HIV/AIDS cases died of AIDS-related diseases in the first year of ART, and the cumulative survival rates at 10 and 18 years of ART were 78.3% and 71.8%, respectively. The proportion of the HIV/AIDS cases with baseline CD4+T lymphocyte (CD4) counts <200 cells/μl at age 15 years when ART started was 45.5% (30 432/66 898). Cox proportional risk regression model showed that, compared with the cases with baseline CD4 counts ≥350 cells/μl, the risk of death was 1.78 times higher than in the cases with CD4 counts <200 cells/μl (95%CI: 1.64-1.94) and 1.24 times higher in the cases with CD4 counts ≥200 cells/μl (95%CI: 1.13-1.36), respectively. The risk of death in symptomatic cases at baseline survey was 1.25 times higher than that in asymptomatic cases (95%CI: 1.16-1.35). The cases with a latest viral load ≥1 000 copies/ml had 7.09 times higher risk of death than those with a last viral load<1 000 copies/ml (95%CI: 6.65-7.54). Conclusions: The majority of HIV/AIDS deaths occurred in the cases aged ≥15 years receiving ART in Henan province during 2002-2019, who were infected through blood-borne transmission and farmers/migrant workers, and AIDS-related diseases were the main causes of the deaths. With the gradual implementation of ART policy, the high survival rate in HIV/AIDS cases can be maintained for a long time in Henan. To reduce the case fatality rate and improve the quality of life of HIV/AIDS patients, CD4 counts test should be further strengthened and eligible HIV/AIDS patients should be covered by standard ART in a timely manner.

Abstract
Study question
Is ERA testing different between RIF patients with control group?
Summary answer
In RIF patients, there were more chances of non-receptive endometrium. ERA testing may be helpful for the patients with repeated IVF failure. What is known already: The endometrium receptivity analysis testing might have the ability to detect the implantation window. In repeat implantation failure patients, detecting of precisely implantation window may have some benefits.
Study design, size, duration
This was a single-center retrospective observational study. Two hundred and forty-nine patients who underwent ERA testing following frozen-thawed embryo transfer in our center were including in this study between January 2019 and May 2020.
Participants/materials, setting, methods
181 patients having unexplained repeated IVF failure (RIF group, at least tow implantation failure) and 68 patients having no experience with embryo transfer (Control group) who underwent ERA testing were including in this study. Both of Patients having a receptive (R) ERA and having a non-receptive (NR) ERA underwent a personalized embryo transfer (pET) on ERA. ERA results and clinical outcomes compared between RIF group and control group were analyzed by Chi-square test.
Main results and the role of chance
The proportion of R/NR results were 33:35 for the RIF group and 118:63 for the Control group, demonstrating the displacement of the window of implantation in patients with RIF. Our results revealed an endometrial factor in 51% RIF patients, which was significantly greater than the Control group 34.8% (P = 0.02). Among the patients with NR ERA result, there are not significantly difference in clinical pregnancy rate in the RIF group compared with control group (57.1%. vs. 61.9%). The clinical pregnancy rate of the patients with receptive ERA result also is comparable in both group (70.3% vs. 66.7%).
Limitations, reasons for caution
This is a retrospective, single center study with limited case number. There were may some bias with ERA testing errors.
Wider implications of the findings: In RIF patients, there were more chances of non-receptive endometrium. ERA testing may be helpful for the patients with repeated IVF failure. Larger randomized studies are required to validate these results.

Abstract
STUDY QUESTION What is the transcriptome signature associated with poor performance of rescue IVM (rIVM) oocytes and how can we rejuvenate them? SUMMARY ANSWER The GATA-1/CREB1/WNT signalling axis was repressed in rIVM oocytes, particularly those of poor quality; restoration of this axis may produce more usable rIVM oocytes. WHAT IS KNOWN ALREADY rIVM aims to produce mature oocytes (MII) for IVF through IVM of immature oocytes collected from stimulated ovaries. It is not popular due to limited success rate in infertility treatment. Genetic aberrations, cellular stress and the absence of cumulus cell support in oocytes could account for the failure of rIVM. STUDY DESIGN, SIZE, DURATION We applied single-cell RNA sequencing (scRNA-seq) to capture the transcriptomes of human in vivo oocytes (IVO) (n = 10) from 7 donors and rIVM oocytes (n = 10) from 10 donors. The effects of maternal age and ovarian responses on rIVM oocyte transcriptomes were also studied. In parallel, we studied the effect of gallic acid on the maturation rate of mouse oocytes cultured in IVM medium with (n = 84) and without (n = 85) gallic acid. PARTICIPANTS/MATERIALS, SETTING, METHODS Human oocytes were collected from donors aged 28-41 years with a body mass index of <30. RNA extraction, cDNA generation, library construction and sequencing were performed in one preparation. scRNA-seq data were then processed and analysed. Selected genes in the rIVM versus IVO comparison were validated by quantitative real-time PCR. For the gallic acid study, we collected immature oocytes from 5-month-old mice and studied the effect of 10-μM gallic acid on their maturation rate. MAIN RESULTS AND THE ROLE OF CHANCE The transcriptome profiles of rIVM/IVO oocytes showed distinctive differences. A total of 1559 differentially expressed genes (DEGs, genes with at least 2-fold change and adjusted P < 0.05) were found to be enriched in metabolic processes, biosynthesis and oxidative phosphorylation. Among these DEGs, we identified a repression of WNT/β-catenin signalling in rIVM when compared with IVO oocytes. We found that oestradiol levels exhibited a significant age-independent correlation with the IVO mature oocyte ratio (MII ratio) for each donor. rIVM oocytes from women with a high MII ratio were found to have over-represented cellular processes such as anti-apoptosis. To further identify targets that contribute to the poor clinical outcomes of rIVM, we compared oocytes collected from young donors with a high MII ratio with oocytes from donors of advanced maternal age and lower MII ratio, and revealed that CREB1 is an important regulator. Thus, our study identified that GATA-1/CREB1/WNT signalling was repressed in both rIVM oocytes versus IVO oocytes and in rIVM oocytes of lower versus higher quality. Consequently we investigated gallic acid, as a potential antioxidant substrate in human rIVM medium, and found that it increased the mouse oocyte maturation rate by 31.1%. LARGE SCALE DATA Raw data from this study can be accessed through GSE158539. LIMITATIONS, REASONS FOR CAUTION In the rIVM oocytes of the high- and low-quality comparison, the number of samples was limited after data filtering with stringent selection criteria. For the oocyte stage identification, we were unable to predict the presence of oocyte spindle, so polar body extrusion was the only indicator. WIDER IMPLICATIONS OF THE FINDINGS This study showed that GATA-1/CREB1/WNT signalling was repressed in rIVM oocytes compared with IVO oocytes and was further downregulated in low-quality rIVM oocytes, providing us the foundation of subsequent follow-up research on human oocytes and raising safety concerns about the clinical use of rescued oocytes.

Abstract
Objective: To explore the associations of urinary retinol binding protein (RBP) and β2-microglobulin (β2-MG) with urinary albumin to creatinine ratio (UACR) and renal function in hospitalized patients with type 2 diabetes mellitus (T2DM). Methods: A total of 1 030 Chinese patients with T2DM were included in this study. The subjects were divided into the UACR normal group (<30 mg/g), microalbuminuria group (30-300 mg/g) and macroalbuminuria group (>300 mg/g). Patients with normal UACR were further divided into two groups according to the estimated glomerular filtration rate (eGFR): the eGFR low group (<90 ml·min-1·1.73m-2) and the normal eGFR group (≥90 ml·min-1·1.73m-2). Urine RBP and β2-MG levels among the groups were compared. Multiple linear regression analyses were applied to evaluate risk factors of urine RBP and β2-MG. Results: In all patients (n=1 030), urine RBP and β2-MG increased gradually with the increase of UACR across the three groups, the proportions of abnormal urine RBP (>0.7 mg/L) and β2-MG (>370 μg/L) in these groups were 3.8%, 8.5%, 39.0% (P<0.001), and 12.9%, 26.7%, 46.8% (P<0.001), respectively. In the UACR normal group (n=788), 12.2% of the patients were with eGFR<90 ml·min-1·1.73m-2. The proportion of abnormal β2-MG (>370 μg/L) was higher in the eGFR low group than that in the eGFR normal group (29.2% vs. 10.7%, P<0.001). Multivariate linear stepwise regression analyses were performed using natural logarithm of urine RBP or β2-MG as dependent variable, and showed that urine RBP was independently associated with UACR (β=0.0005, P<0.001), serum creatinine (β=0.006, P<0.001) and glycosylated hemoglobin A1c (β=0.050, P=0.001), and β2-MG was independently correlated with UACR (β=0.000 4, P<0.001), serum creatinine (β=0.011, P<0.001), systolic blood pressure (β=0.005, P=0.031) and fasting blood-glucose (β=0.027, P=0.046). Conclusions: Urine RBP and β2-MG are positively associated with high UACR and impaired renal function in T2DM patients, and these changes could occur before UACR and eGFR turned out to be abnormal. It is recommended that urine RBP and β2-MG be detected as early as possible to identify diabetic kidney disease in patients with normal UACR and eGFR.

Abstract
Due to the rapid progression and poor prognosis of esophageal cancer (EC), the early detection and diagnosis of early EC are of great value for the prognosis improvement of patients. However, the endoscopic detection of early EC, especially Barrett's dysplasia or squamous epithelial dysplasia, is difficult. Therefore, the requirement for more efficient methods of detection and characterization of early EC has led to intensive research in the field of artificial intelligence (AI). Deep learning (DL) has brought about breakthroughs in processing images, videos, and other aspects, whereas convolutional neural networks (CNNs) have shone lights on detection of endoscopic images and videos. Many studies on CNNs in endoscopic analysis of early EC demonstrate excellent performance including sensitivity and specificity and progress gradually from in vitro image analysis for classification to real-time detection of early esophageal neoplasia. When AI technique comes to the pathological diagnosis, borderline lesions that are difficult to determine may become easier than before. In gene diagnosis, due to the lack of tissue specificity of gene diagnostic markers, they can only be used as supplementary measures at present. In predicting the risk of cancer, there is still a lack of prospective clinical research to confirm the accuracy of the risk stratification model.

Abstract
AIM To evaluate the clinical value of abnormal laboratory results of multiple organs in patients with coronavirus disease 2019 (COVID-2019) and to help clinicians perform correct treatment. RESULTS Elevated neutrophil-to-LYM ratio (NLR), D-dimer(D-D), interleukin (IL)-6, IL-10, IL-2, interferon-Y, and age were significantly associated with the severity of illness. However, significant and sustained decreases were observed in the LYM subset (p<0.05). D-D, T cell counts, and cytokine levels in severe COVID-19 patients who survived the disease gradually recovered at later time points to levels that were comparable to those of mild cases. Second, D-D increased from 0.5 to 8, and the risk ratio increased from 2.75 to 55, eventually leading to disseminated intravascular coagulation. Moreover, the acute renal function damage occurred earlier than abnormal heart and liver functions (p<0.05). CONCLUSIONS The degrees of lymphopenia and proinflammatory cytokine storm were higher in severe COVID-19 patients than in mild cases. The degree was associated with the disease severity. Advanced age, NLR, D-D, and cytokine levels may serve as useful prognostic factors for the early identification of severe COVID-19 cases. METHODS Peripheral blood samples were collected from 93 confirmed COVID-19 patients. The samples were examined for lymphocyte (LYM) subsets by flow cytometry and cytokine profiles by specific immunoassays. The receiver operating characteristic curve was applied to determine the best diagnostic thresholds for laboratory results, and principal component analysis was used to screen the major risk factors. The prognostic values were assessed using the Kaplan-Meier curve and univariate and multivariate COX regression models.

Abstract
The catalyst-free domino reaction of α,β-unsaturated N-alkyl or N-arylaldimines with two molecules of 2-arylidene-1,3-indanediones in dry acetonitrile resulted in polysubstituted spiro[indene-2,3'-indeno[2',1':5,6]pyrano[2,3-b]pyridines] in moderate to good yields and with high diastereoselectivity. The reaction mechanism included sequential aza/oxa-Diels-Alder reactions via both endo-transition states. On the other hand, the catalyst-free domino reaction of α,β-unsaturated N-arylaldimines with 2,2'-(arylmethylene)bis(1,3-indenediones) afforded the mixed diastereoisomeric dispiro[indene-2,1'-cyclohexane-3',2″-indene] derivatives in satisfactory yields. The reaction mechanism of this formal [3 + 3] cycloaddition was believed to proceed with sequential nucleophilic 1,4-/1,2-additions.

Abstract
Objective: To understand the major high risk behaviors and related factors among reported HIV/AIDS cases aged ≥60 years in some areas of Henan province. Methods: In Dengzhou, Xunxian county of Hebi and Xiangcheng county of Xuchang, where the reported number and proportion of HIV/AIDS cases aged ≥60 years were high, a face to face interview was conducted among the cases aged ≥60 years during July-August in 2016. The information about the high risk behaviors before HIV infection confirmation were collected by using a semi-structured questionnaire. Results: A total of 33 HIV/AIDS cases aged ≥60 years were interviewed, including 28 males and 5 females. Their average age was 67.4 years. The infection route was sexual contact. The main findings revealed that the main factor for HIV infection in elder males was commercial heterosexual behavior with local female sex workers. The condom use rate was low. The poor awareness of the knowledge about AIDS prevention could explain why the elderly could not recognize the risk of HIV infection. There were also homosexual and bisexual behaviors in elder male HIV/AIDS patients. Late detection of HIV transmission among couples was the main cause of HIV infection in elder women. Conclusions: The major epidemiological related factors for HIV infection in the elderly in some areas of Henan were unsafe sex behavior and the poor awareness of knowledge about AIDS prevention. A targeted strategy should be taken to control the spread of HIV in the elderly.

Abstract
Objective: To investigate the role of neutrophil elastase inhibitor, sivelestat, in preventing and treating nonalcoholic steatohepatitis (NASH) and its underling mechanisms. Methods: A total of forty 4-week-old male C57BL/6J ApoE-/-mice were equally divided into the following four groups: standard chow (SC)+isotonic saline; SC+sivelestat; high-fat, high-cholesterol (HFHC) diet+isotonic saline; and HFHC+sivelestat. These mice were treated with above methods for 12 weeks. Blood and liver tissue samples were collected to measure biochemical parameters, hepatic steatosis and non-alcoholic fatty liver disease (NAFLD) activity score (inflammation) were evaluated by oil red O staining and HE staining, respectively. The mRNA and protein expression levels of hepatic inflammatory cytokines, CD68, and F4/80 were determined by quantitative RT-PCR and immunohistochemistry, respectively. Comparison of means between the four groups was made by one-way analysis of variance, and comparison between any two groups was made by the LSD or SNK method (for data with homogeneity of variance) or the Tamhane or Dunnett method (for data with heterogeneity of variance). Results: Mice fed with an HFHC diet for 12 weeks developed typical pathological features of NASH compared with those fed with SC. Compared with mice fed with HFHC diet without sivelestat, those treated with HFHC and sivelestat exhibited the following features: (1) significantly reduced fast blood glucose, blood cholesterol, and hepatic biochemical parameters, as well as increased insulin sensitivity; (2) significantly reduced NAFLD activity score (5.71±1.11 vs 3.16±1.16, P < 0.05); (3) reduced monocyte chemoattractant protein-1 and tumor necrosis factor -α; (4) significantly reduced mRNA levels of CD68 and F4/80; and (5) reduced expression of CD68 in the liver. Conclusion: Sivelestat alleviates the hepatic steatosis and inflammation of NASH in mice by inhibiting the activation of Kupffer cells.

Abstract
Objective: To assess the association and intensity of baseline TC level with the incidence of lung cancer in men in China. Methods: Since May 2006, all the male workers, including the employees and the retirees in Kailuan Group were recruited in the Kailuan male dynamic cohort study. Information about demographics, medical history, anthropometry and TC level were collected at the baseline interview, as well as the information of newly-diagnosed lung cancer cases during the follow-up period. According to guidelines for blood lipids in Chinese adults and the distribution in the population, TC level was classified into five groups as followed: <160, 160-, 180-, 200- and ≥240 mg/dl, with the second quintile group (160- mg/dl) serving as the referent category. Cox proportional hazards regression model and restricted cubic spline (RCS) model were used to evaluate the association and the nonlinear association between baseline TC level and the risk of lung cancer in the men. Results: By December 31, 2014, for the 109 884 men, a follow up of 763 819.25 person-years was made with a median follow-up period of 7.88 years. During the follow up, 808 lung cancer cases were identified. After adjustment for age, education level, income level, smoking status, alcohol consumption level, history of dust exposure, FPG level and BMI, HR (95%CI) of lung cancer for men with lower TC level (<160 mg/dl) and higher TC level (≥240 mg/dl) were 1.34 (1.04- 1.72) and 1.45 (1.09-1.92), respectively, compared with men with normal TC level (160- mg/dl). The results didn't change significantly after exclusion of newly diagnosed cancer cases within 2 years of follow up and subjects with the history of hyperlipidemia. Conclusion: Our results showed that TC might be associated with higher risk of lung cancer. Men with lower TC level or higher TC level had higher risk for lung cancer. Keep moderate TC level might be one of the effective precaution for the prevention of lung cancer.

Abstract
Previous studies have suggested that microsomal prostaglandin E synthase-1 (mPGES-1) is highly expressed and closely associated with mitogen-activated protein kinase (MAPK) signaling pathways in various types of malignant cells. However, their expression patterns and function with respect to T-cell acute lymphoblastic leukemia (T-ALL) remain largely unknown. The present study investigated whether mPGES-1 served a crucial role in T-ALL and aimed to identify interactions between mPGES-1 and the MAPK signaling pathway in T-ALL. The results indicated that mPGES-1 overexpression in T-ALL jurkat cells was significantly decreased by RNA silencing. Decreasing mPGES-1 on a consistent basis may inhibit cell proliferation, induce apoptosis and arrest the cell cycle in T-ALL jurkat cells. Microarray and western blot analyses revealed that c-Jun N-terminal kinase served a role in the mPGES-1/prostaglandin E2/EP4/MAPK positive feedback loops. In addition, P38 and extracellular signal-regulated kinase 1/2 exhibited negative feedback effects on mPGES-1. In conclusion, the results suggested that cross-talk between mPGES-1 and the MAPK signaling pathway was very complex. Therefore, the combined regulation of mPGES-1 and the MAPK signaling pathway may be developed into a new candidate therapy for T-ALL in the future.

Abstract
Nimotuzumab is a blocking monoclonal antibody against epidermal growth factor receptor (EGFR). However, little is known about the safety and preliminary efficacy of nimotuzumab combined with concurrent chemoradiotherapy in locally advanced NPC patients. A total of 42 patients diagnosed between 2011 and 2013 were enrolled. Our results demonstrated 38 patients had a complete response (90.5%), 4 patients had a partial response (9.5%). And no patients had progressive disease at early treatment response evaluation, giving an ORR of 100%. The 2-year local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) and overall survival (OS) were 96.4%, 93.1% and 96.6% respectively. The most common adverse events were mucositis (19 patients), hematology toxicity (14 patients) with 6 and 3 cases of grade 3/4 toxicity respectively. Skin rash was not developed in our 43 patients. Thus, nimotuzumab combined with concurrent chemoradiotherapy showed encouraging outcomes in the treatment of locally advanced nasopharyngeal carcinoma, without accumulation of toxicity and well-tolerated.

Abstract
Objective: To investigate whether elevated levels of high sensitivity C-Reactive Protein (hsCRP) and neutrophil (NE) at baseline are associated with an increased risk of colorectal cancer in Kailuan male cohort. Methods: Since May 2006, males from Kailuan cohort were included in this study. Information on demographics, medical history, anthropometry, hsCRP and NE were collectedat baseline for all subjects. Multivariable Cox proportional hazards regression models were used to calculate hazard ratios (HR) of association between baseline hsCRP and NE and colorectal cancer risk. Results: By December 31, 2015, a total of 73 869 participants were enrolled in this study. During the follow-up, 336 incident colorectal cancer cases were identified. All participants were divided into three groups according to the level of hsCRP (<1 mg/L, 1-3 mg/L and >3 mg/L). The cumulative incidence of colorectal cancer were 456/10(5,) 510/10(5) and 746/10(5) in these 3 groups, respectively (χ(2)=10.79, P=0.005). Compared with participants with lower hsCRP levels (<1 mg/L), individuals with the highest hsCRP (>3 mg/L) levels had significant increased risks of colorectal cancer (HR=1.38, 95%CI: 1.05-1.81, P=0.020)after adjusting for age, gender, smoking, drinking, BMI, diabetes and income. Furthermore, subjects were divided into two groups according to the level of NE (≤ 4.08×10(9)/L and > 4.08×10(9)/L). Multivariable Cox proportional hazards regression models indicated that there is no statistical significance of association between NE and colorectal cancer. Conclusions: Elevated levels of hsCRP at baseline might increase the risk of colorectal cancer in males.

Abstract
Urban road runoff contains pollutants such as particulate matters, organic chemicals, heavy metals, nutrients, oil and grease that can cause significant degradation of receiving water quality. Eliminating the pollutant mass loading of road runoff and protecting the receiving water bodies have been the focuses in environmental field in recent years. To accomplish pollutant reduction and develop a cost-effective treatment method, knowledge of water quality characteristics, as well as the pollutant effluent characteristics of road runoff is required. In order to investigate the impacts of rainfall characteristics and occurrence of pollutant on the variation of pollutant concentrations during the duration of runoff events and pollutant load effluent characteristics of road runoff, 207 road runoff samples in the durations of 13 storm events occurred at Taibai Interchange of the south second-ring road in Xi'an, Shaanxi province from July 2014 to September 2015 were collected by the manual time-interval sampling method, and concentrations of SS, COD, dissolved COD, Cu, dissolved Cu, Pb, dissolved Pb, Cr, dissolved Cr, Cd and dissolved Cd of the samples were determined. The results indicated that, the road runoff of Xi'an city was seriously polluted by SS and COD, which were the main contaminants in road runoff. Meanwhile, concentrations of Pb and Cr in road runoff were also at a high level. The variation of pollutant concentrations during the duration of runoff was closely related to rainfall characteristics and occurrence states of the pollutants. Emission of the dissolved pollutants was not affected by the type of rainfall. The concentration of the dissolved pollutants in the runoff reached a peak in the initial duration of runoff, and then, decreased continuously. However, the peak concentration of particulate pollutants in the runoff only occurred after the peak of sufficiently large rainfall intensity. The concentration of particulate pollutants in the runoff fluctuated sharply with the variation of rainfall intensity, and impacted by the rainfall duration and rainfall depth as well. Rainfall characteristics didn't have a great impact on the load emission of the dissolved pollutants, therefore, had a significant influence on the load emission of the particulate pollutants. Compared with the rainfall type Ⅲ, first flush effects of pollutant loads of SS, COD, Cu, Pb, Cr, Cd in rainfall type Ⅰand type Ⅱ were more obvious. Besides, first flush effect of pollutant loads was not ubiquitous. All the pollutants in the monitoring 13 runoff events didn't exhibit an obvious first flush effect. The descending order of the first flush effect of those pollutants was COD, SS, dissolved COD, Cu, Pb, Cr, dissolved Cu, Cd, dissolved Pb, dissolved Cr, dissolved Cd.

Abstract
OBJECTIVE To study the survival effect of AIDS patients after the antiretroviral treatment that initiated at different times and to understand the factors associated with the survival time. METHODS Information on AIDS patients who started receiving the antiretroviral therapy during 2002-2014 was collected from the Chinese HIV/AIDS Integrated Control System in Henan province. According to the level of baseline immunology, all the participants were divided into earlier treatment group [Baseline CD4(+)T lymphocyte cell counts (CD4) between 350/μl and 500/μl] or conventional treatment group (Baseline CD4 cell counts≤350/μl). Data was analyzed with both Survival and Review methods. RESULTS A total number of 37 169 cases were selected, including 32 129 cases in the conventional treatment group and 5 040 cases in the earlier treatment group. Mortalities in the conventional treatment group and earlier treatment group were 4.3/100 person year and 1.8/100 person year, respectively. Data on the 11-year cumulative survival rate of both the conventional treatment group and earlier treatment group were 67.9% and 82.3%, respectively. By means of multi-variable analysis, we found that factors as gender, age, marital status, route of infection, number of symptoms, missed taking drugs in the past 7 days, degree of education at baseline of conventional treatment group etc. were associated with survival time of patients after the initiation of antiretroviral treatment (ART) (P<0.05) while factors as gender, age, marital status, ever missed taking drugs in the past 7 days at baseline etc. in the earlier treatment group were associated with the survival time of patients after the ART initiation (P<0.05). CONCLUSION Strategy including earlier initiation of antiretroviral treatment on AIDS patients who had met the treatment criteria and programs related to the improvement on adherence to medication, could prolong the survival time of AIDS patients, in Henan province.

Abstract
OBJECTIVE To understand the hepatitis C virus infection status and related risk factors in drug users in Henan province during 2011-2015 and provide scientific evidence for the development of HCV infection prevention and control measures. METHODS Cross-sectional questionnaire surveys were conducted among the drug users and blood samples were taken from them for HCV antibody detection during HIV sentinel surveillance period in Henan province from April to June during 2011-2015. RESULTS The HCV infection rate in drug users increased from 3.70% in 2011 to 6.54% in 2015 (trend χ(2)=25.93, P<0.01). Multivariate analysis indicated that HCV infection related risk factors included age older (OR=1.23, 95% CI: 1.13-1.35, P=0.00), place of domicile (OR=3.45, 95%CI: 2.59-4.60, P=0.00), traditional drug user or mixed drug user (OR=1.46, 95%CI: 1.10-1.93, P=0.01; OR=1.82, 95%CI: 1.18-2.81, P=0.01), injecting drug user (OR=2.88, 95%CI: 2.45-3.39, P=0.00), commercial sex behavior in recent one year (OR=1.44, 95%CI: 1.20-1.72, P=0.00) and drug user in compulsory drug rehabilitation or those receiving methadone maintenance treatment (OR=1.79, 95% CI: 1.28-2.50, P=0.00; OR=1.74, 95% CI: 1.17-2.58, P=0.01). CONCLUSION The HCV infection rate in drug users was higher in Henan and increased rapidly with years. In order to control HCV spread, it is necessary to strengthen the management of drug users and take effective intervention measures.

Abstract
MicroRNA-146a (miR-146a) is associated with human inflammatory disease, such as thyroid-associated ophthalmopathy (TAO), but its role in human T cells and relevance to TAO remains ambiguous. In this study, T cells of TAO patients showed downregulated expression of miR-146a. We characterized miR-146a in T cells and examined miR-146a as a critical inhibitor of Th1 differentiation processes. MiR-146a inhibited Th1 differentiation processes and cell proliferation of T-lymphocytes. Thus, the results showed that miR-146a was a potent inhibitor of Th1 differentiation and cell proliferation of human T cells and dysregulation of miR-146a contributed to the pathogenesis of TAO.

Abstract
Drought potentially affects carbon balance and growth of trees, but little is known to what extent soil plays a role in the trade-off between carbon gain and growth investment. In the present study, we analyzed leaf non-structural carbohydrates (NSC) as an indicator of the balance of photosynthetic carbon gain and carbon use, as well as growth of European beech (Fagus sylvatica L.) saplings, which were grown on two different soil types (calcareous and acidic) in model ecosystems and subjected to a severe summer drought. Our results showed that drought led in general to increased total NSC concentrations and to decreased growth rate, and drought reduced shoot and stem growth of plants in acidic soil rather than in calcareous soil. This result indicated that soil type modulated the carbon trade-off between net leaf carbon gain and carbon investment to growth. In drought-stressed trees, leaf starch concentration and growth correlated negatively whereas soluble sugar:starch ratio and growth correlated positively, which may contribute to a better understanding of growth regulation under drought conditions. Our results emphasize the role of soil in determining the trade-off between the balance of carbon gain and carbon use on the leaf level and growth under stress (e.g. drought).

Abstract
OBJECTIVE To investigate the quality of life and its related factors among HIV/AIDS patients from HIV serodiscordant couples in Zhoukou city of Henan province. METHODS During January to May in 2015, by the convenience sample, World Health Organization Quality of Life Questionnaire for Brief Version (WHOQOL-BREF) (Chinese version) and a self-edited questionnaire were used to investigate 1 251 HIV/AIDS patients who were confirmed with HIV positive by local CDC, registered in"HIV serodiscordant family" and agreed to participate in a face-to-face interview with above 18 year-old based on the local CDC , township hospitals and village clinics of 9 counties and 1 district of Zhoukou city, excluding the HIV/AIDS patients who were in divorce, death by one side, unknowing about his HIV status, with mental illness and disturbance of consciousness, incorrectly understanding the content of the questionnaire, and reluctant to participate in this study. The scores of quality of life of physical, psychological, social relations, and environmental domain were calculated. The related factors of the scores of different domains were analyzed by Multiple Two Classification Unconditioned Logistic Regression. RESULTS The scores of investigation objects in the physical, psychological, social relations, and environmental domain were 12.00± 2.02, 12.07 ± 2.07, 11.87 ± 1.99, and 11.09 ± 1.84, respectively. The multiple Unconditioned Logistic Regression analysis indicated that age <40 years, on ART and no other sickness in last two weeks were beneficial factors associated with physical domain with OR (95%CI): 0.61 (0.35-1.06), 0.52 (0.30-0.90), and 1.66 (1.09-2.52), respectively. The possibility of no poverty and no other sickness in last two weeks increased to 0.15(0.09-0.26) and 1.57(1.06-2.33) times of those who was in poverty and with other sickness in last two weeks in physical domain. The possibility of participants who were below 40 years old and with children increased to 0.58 (0.34-0.98) and 0.37 (0.23-0.57) times of who were above 40 years old and without children in psychological domain. The factors of with AIDS related symptoms, no children and with other sickness in last two week were found to be significantly associated with environmental domain with OR (95%CI): 0.65 (0.48-0.88), 0.66 (0.51-0.85), and 0.65 (0.51-0.84), respectively . CONCLUSION The scores of every domain of quality of life in HIV serodiscordant couples of Zhoukou city were good. Age, whether having AIDS related symptoms, whether to accept ART , children, status of poverty, and whether suffering from other diseases in last two weeks were the main factors associated with the quality of life.

Abstract
Chinese Fusion Engineering Test Reactor (CFETR) is a new superconducting tokamak device being designed in China, which aims at bridging the gap between ITER and DEMO, where DEMO is a tokamak demonstration fusion reactor. Two diagnostic cases, ITER-like case and towards DEMO case, have been considered for CFETR early and later operating phases, respectively. In this paper, some preliminary consideration of ITER-like case will be presented. Based on ITER diagnostic system, three versions of increased complexity and coverage of the ITER-like case diagnostic system have been developed with different goals and functions. Version A aims only machine protection and basic control. Both of version B and version C are mainly for machine protection, basic and advanced control, but version C has an increased level of redundancy necessary for improved measurements capability. The performance of these versions and needed R&D work are outlined.

Abstract
BACKGROUND The aim of this study was to determine whether neutrophil CD64 (nCD64) combined with procalcitonin (PCT), C-reactive protein (CRP) and white blood cell count (WBC) can increase the sensitivity and accuracy of neonatal sepsis diagnosis. METHODS The serum levels of nCD64, CRP, PCT and WBC were detected in 60 patients with neonatal sepsis and 60 patients with non-sepsis. Sensitivity, specificity, positive and negative predictive values, receiver operating characteristic (ROC) area under the curve (AUC), and logistic regression analysis were performed to evaluate the diagnostic value of these markers on neonatal sepsis. RESULTS Serum levels of nCD64, PCT, CRP and WBC were higher in the sepsis group than non-sepsis group (p<0.001). The sensitivities of nCD64, PCT, CRP and WBC at the recommended cut-off level for all infants were 79.5%, 68.2%, 38.6% and 52.3%, respectively. The best combination was nCD64 and PCT, which obtained sensitivity of 90.9%, largest AUC of 0.922, and a negative predictive value of 89.2%. However by using an optimal cut-off value, the sensitivities of all four biomarkers for the diagnosis of neonatal sepsis were increased to 95.5%. Except for WBC, the birth weight and gestational age had no effects on the diagnostic value of these serum biomarkers. CONCLUSIONS nCD64 and PCT are better diagnostic biomarkers for early diagnosis of neonatal sepsis as compared to CRP. With the help of optimal cut-off value based on ROC curve and logistic regression analysis, the combination of these biomarkers could improve the sensitivity for the diagnosis of suspected late-onset neonatal sepsis based on common serum biomarkers.

Abstract
OBJECTIVE To establish an apolipoprotein E (ApoE) and low-density lipoprotein receptor (LDLR) double-knockout (ApoE(-/-)/LDLR(-/-)) mouse model of nonalcoholic steatohepatitis (NASH)-related hepatocellular carcinoma (HCC) induced by high-fat and high-cholesterol (HFHC) diet. METHODS ApoE(-/-) knockout mice were crossed with LDLR(-/-) knockout mice to obtain ApoE(-/-)/LDLR(-/-) mice. The ApoE(-/-)/LDLR(-/-) mice mated with each other, and the offspring were injected with low-dose streptozotocin (STZ) at 2-3 days after birth. Some mice were fed with HFHC diet after weaning as the model group (n = 15), and some mice were fed with normal diet as the control group (n = 15). Mice were sacrificed at the end of weeks 10, 16, and 20 (5 mice at each time point). The body weight was measured. Liver tissue and blood were collected to measure biochemical parameters, evaluate the pathological changes in the liver tissue by HE staining, oil red O staining, and Masson staining, and detect the expression of glypican-3 (a marker of HCC) by immunohistochemical staining. RESULTS The model group had significantly higher levels of fasting blood glucose and total cholesterol than the control group (P < 0.01). Serum levels of alanine aminotransferase, aspartate aminotransferase, and total triglyceride gradually increased with time in the model group; at week 20, there were significant differences in above three indices between the two groups (P < 0.05). HE staining showed that compared with the control group at the corresponding time point, the model group developed sequential histological changes: NASH at week 10, dysplastic nodules at week 16, and early HCC at week 20. Oil red O staining showed that in the model group, the degree of liver steatosis increased within 10 weeks and gradually decreased later. Masson staining demonstrated that the model group developed pathological changes: mild perisinusoidal fibrosis at week 16 and bridging fibrosis around tumors at week 20. HE staining, oil red O staining, and Masson staining showed that no histological or pathological changes were found in the control group. Glypican-3 was detected in the nodules at week 16 and in the cytoplasm of HCC cells at week 20 in the model group. CONCLUSION The mouse model of NASH-related HCC can be developed by giving STZ injection to neonatal ApoE(-/-)/LDLR(-/-) mice and feeding them with HFHC diet after weaning for 20 weeks. Early HCC may develop directly from NASH.

Abstract
OBJECTIVE To investigate the relationship between liver cancer and the water environment, we analyzed the life expectancy in 14 counties (districts), which form the Huai River Basin with respect to liver cancer deaths in 2013 and changes in the surface water quality from 2004 to 2010. METHODS The study area included the 14 counties (districts) of the Huai River Basin in China. We obtained surveillance data for all causes of death in the study area during 2013, as well as data for International Classification of Diseases,Tenth Edition(ICD-10) code C22 or liver cancer. Life expectancy and life expectancy after elimination of liver cancer were then calculated. Based on water quality monitoring data from the China Environment Yearbook 2005-2011, we analyzed the water environment of the Huai River Basin, and changes in the water quality. According to the " Encyclopedia of Rivers and Lakes in China" (Huai River Basin section), we divided the river basin into five categories: upstream basin (upstream); midstream, north shore of the basin (midstream-north); midstream, south shore of the basin (midstream-south); downstream basin (downstream); and the Yishusi River Basin. To calculate the life expectancy and life expectancy after elimination of liver cancer in the study area, we used the Nemerow Pollution Index (NPI), to investigate the relationship between liver cancer and the water environment. RESULTS Life expectancy in the 14 study districts varied from 68.99 years (Shenqiu County) to 78.85 years (Jinhu County). Gains in life expectancy after elimination of liver cancer varied from 0.86 to 0.31 years. Midstream-north showed the greatest improvement, with overall gain in life expectancy of 0.77 years; this gain was 1.04 years for males and 0.40 years for females. Yishusi River Basin showed the least improvement, with overall gain in life expectancy of 0.41 years; this gain was 0.54 years for males and 0.24 years for females. For the 7 years from 2004 to 2010, midstream-north had the highest annual NPI values, at 2.08, 1.74, 1.64, 1.81, 1.41, 1.26, and 1.06, respectively. There was a positive correlation between NPI and life expectancy gain for both males and females (r=0.64, P=0.014). There was positive correlation between NPI and life expectancy gain among males alone (r=0.64, P=0.014); there was no significant correlation between NPI and life expectancy gain among females (r=0.44, P=0.115). CONCLUSION Liver cancer had a significant impact on life expectancy in the Huai River Basin. The gain in life expectancy was higher for males than for females. There is a possible relationship between liver cancer deaths and the water environment in the research area, but this study did not infer a causal association.

Abstract
Abnormal angiogenesis is critical for portal hypertension in cirrhosis. Except for etiological treatment, no efficient medication or regime has been explored to treat the early stage of cirrhosis when angiogenesis is initiated or overwhelming. In this study, we explored an anti-angiogenesis effort through non-cytotoxic drugs octreotide and celecoxib to treat early stage of cirrhotic portal hypertension in an animal model. Peritoneal injection of thioacetamide (TAA) was employed to induce liver cirrhosis in rats. A combination treatment of celecoxib and octreotide was found to relieve liver fibrosis, portal venous pressure, micro-hepatic arterioportal fistulas, intrahepatic and splanchnic angiogenesis. Celecoxib and octreotide exerted their anti-angiogenesis effect via an axis of cyclooxygenase-2/prostaglandin E2/EP-2/somatostatin receptor-2, which consequently down-regulated phosphorylation of extracellular signal-regulated kinase (p-ERK)–hypoxia-inducible factor-1α (HIF-1α)–vascular endothelial growth factor (VEGF) integrated signaling pathways. In conclusions, combination of celecoxib and octreotide synergistically ameliorated liver fibrosis and portal hypertension of the cirrhotic rats induced by TAA via the inhibition of intrahepatic and extrahepatic angiogenesis. The potential mechanisms behind the regimen may due to the inactivation of p-ERK–HIF-1α–VEGF signaling pathway.

Abstract
Mitochondrial DNA mutations that lead to mitochondrial dysfunction have long been proposed to play important roles in the development of pancreatic cancer. Of these, alterations to mitochondrial tRNA genes constitute the largest group. Most recently, a variation at position 12307 in the gene encoding tRNA(Leu(CUN)) has been reported to be associated with this disease. However, the molecular mechanism underlying this relationship remains poorly understood. To assess this association, we evaluated this variant by evolutionary conservation analysis, measurements of allelic frequencies among control subjects, and use of several bioinformatic tools to estimate potential structural and functional alterations. We found this residue to have a high conservation index; however, the presence of the A12307G variation in control subjects revealed by a literature search suggested it to be common in human populations. Moreover, RNAfold results showed that this variant did not alter the secondary structure of tRNA(Leu(CUN)). Through the application of a pathogenicity scoring system, this variant was determined to be a "neutral polymorphism," with a score of only 4 points based on current data. Thus, the contribution of the A12307G variant to pancreatic cancer needs to be addressed in further experimental studies.

Abstract
Inflammatory transport through the gut-liver axis may facilitate liver cirrhosis. Cyclooxygenase-2 (COX-2) has been considered as one of the important molecules that regulates intestinal epithelial barrier function. This study was aimed to test the hypothesis that inhibition of COX-2 by celecoxib might alleviate liver cirrhosis via reduction of intestinal inflammatory transport in thiacetamide (TAA) rat model. COX-2/prostaglandin E2 (PGE2)/EP-2/p-ERK integrated signal pathways regulated the expressions of intestinal zonula occludens-1 (ZO-1) and E-cadherin, which maintain the function of intestinal epithelial barrier. Celecoxib not only decreased the intestinal permeability to a 4-kDa FITC-dextran but also significantly increased expressions of ZO-1 and E-cadherin. When celecoxib greatly decreased intestinal levels of LPS, TNF-α, and IL-6, it significantly enhanced T cell subsets reduced by TAA. As a result, liver fibrosis induced by TAA was significantly alleviated in the celecoxib group. These data indicated that celecoxib improved the integrity of intestinal epithelial barrier, blocked inflammatory transport through the dysfunctional gut-liver axis, and ameliorated the progress of liver cirrhosis.

Abstract
Renal cell carcinoma (RCC) is the most lethal of all genitourinary malignancies. NEDD9/HEF1/Cas-L is a member of the Cas protein family and is known as a biomarker in multiple cancer types. In this study, we demonstrate for the first time that NEDD9 was upregulated in RCC tissue and cell lines. Immunohistochemical analysis and quantitative RT-PCR analysis showed low expression of NEDD9 in normal renal tissues and high expression in RCC tissues. In addition, in vitro experiments show that expression of NEDD9 was upregulated in RCC cell lines. Through MTT assay, we observed that NEDD9 knockdown inhibited cell proliferation. Furthermore, flow cytometry analysis showed that NEDD9 downregulation induced apoptosis. Together, our data suggest that abnormal NEDD9 protein expression may be a marker for RCC, and NEDD9 knockdown suppresses cell growth.
