Abstract
BACKGROUND The gut microbiota is a critical factor in the regulation of host health, but the relationship between the differential resistance of hosts to pathogens and the interaction of gut microbes is not yet clear. Herein, we investigated the potential correlation between the gut microbiota of piglets and their disease resistance using single-cell transcriptomics, 16S amplicon sequencing, metagenomics, and untargeted metabolomics. RESULTS Porcine epidemic diarrhea virus (PEDV) infection leads to significant changes in the gut microbiota of piglets. Notably, Landrace pigs lose their resistance quickly after being infected with PEDV, but transplanting the fecal microbiota of Min pigs to Landrace pigs alleviated the infection status. Macrogenomic and animal protection models identified Lactobacillus reuteri and Lactobacillus amylovorus in the gut microbiota as playing an anti-infective role. Moreover, metabolomic screening of the secondary bile acids' deoxycholic acid (DCA) and lithocholic acid (LCA) correlated significantly with Lactobacillus reuteri and Lactobacillus amylovorus, but only LCA exerted a protective function in the animal model. In addition, LCA supplementation altered the distribution of intestinal T-cell populations and resulted in significantly enriched CD8+ CTLs, and in vivo and in vitro experiments showed that LCA increased SLA-I expression in porcine intestinal epithelial cells via FXR receptors, thereby recruiting CD8+ CTLs to exert antiviral effects. CONCLUSIONS Overall, our findings indicate that the diversity of gut microbiota influences the development of the disease, and manipulating Lactobacillus reuteri and Lactobacillus amylovorus, as well as LCA, represents a promising strategy to improve PEDV infection in piglets.

Abstract
As a representative work of materia medica in the Ming Dynasty, the plant images attached to Compendium of Materia Medica retain the results of Li Shizhen's research on the original plants of medicinal materials in another form, which truly reflects the understanding and utilization of herbs in the Ming Dynasty.Taking the image of fragrant plants in Wood section in the book as an example, the original of the plants depicted in the images is examined to reveal the level of understanding of plant knowledge and medicinal properties in the Ming dynasty.Among the 25 images contained in the woody section, 20 images accurately depict the leaves, flowers and fruits of plants, and the description of the morphological details of the plant Cephalotaxus fortunei Hook. f. proves a high level of understanding of plant morphology and medicinal properties at the time. However, the errors of a total of 5 diagrams such as Wuyao and A wei also showed limitations. By comparing the results of the image with the medicinal properties contained in the text,it is clear that the level of understanding of medicinal properties is very high in the Ming dynasty, and the understanding of the medicinal properties of some plants is even higher than the understanding of their morphology.

Abstract
The contamination of food by pathogens is a serious problem in global food safety, and current methods of detection are costly, time-consuming, and cumbersome. Therefore, it is necessary to develop rapid, portable, and sensitive assays for foodborne pathogens. In addition, assays for foodborne pathogens must be resistant to interference resulting from the complex food matrix to prevent false positives and negatives. In this study, hemin and reduced graphene oxide-MoS2 sheets (GMS) were used to design a near-infrared (NIR)-responsive photoelectrochemical (PEC) aptasensor with target-induced photocurrent polarity switching based on a hairpin aptamer (Hp) with a G-quadruplex motif. A ready-to-use analytical device was developed by immobilizing GMS on the surface of a commercial screen-printed electrode, followed by the attachment of the aptamer. In the presence of Escherichia coli O157:H7, the binding sites of Hp with the G-quadruplex motif were opened and exposed to hemin, leading to the formation of a G-quadruplex/hemin DNAzyme. Crucially, after binding to hemin, the charge transfer pathway of GMS changes, resulting in a switch of the photocurrent polarity. Further, G-quadruplex/hemin DNAzyme enhanced the cathodic photocurrent, and the proposed sensor exhibited a wide linear range ((25.0-1.0) × 107 CFU/mL), a low limit of detection (2.0 CFU/mL), and good anti-interference performance. These findings expand the applications of NIR-responsive PEC materials and provide versatile PEC methods for detecting biological analytes, especially for food safety testing.

Abstract
In order to understand the heavy metal contamination of soil and vegetables in the vegetable production system of Zhejiang Province and the health risks of vegetables consumed by residents, typical vegetable production bases in Zhejiang Province were selected as the study areas; 102 pairs of vegetable and soil samples were collected; the distribution characteristics of heavy metals Cd, Cu, Pb, Cr, As, Ni, and Hg in the vegetable production system of Zhejiang Province were analyzed, and the ecological health risks of the vegetable production system were systematically evaluated using the Nemerow composite pollution index, potential ecological risk index, and dietary exposure assessment model. The results showed that Cd in the soil seriously exceeded the standard, with an exceedance rate of 97.2%. The main risk of soil pollution was moderate and mild, and the highest risk was Cd, followed by Pb, Cu, and As. Among vegetables, only a small amount of bean and fruit vegetables exceeded the Cd content, with the exceedance rates of 12.5% and 8.7%, respectively. The BCF of different types of vegetables differed significantly and could be ranked accordingly:leafy vegetables>bean vegetables>melon vegetables>root vegetables. The non-carcinogenic and carcinogenic risks of Zhejiang residents consuming local vegetables were within acceptable limits, with children being more at risk than adults (P<0.01), and Cd and Pb contributing the most to health risks. The overall vegetables produced by the vegetable production system in Zhejiang Province were at a safe level, but there is a need to strengthen the control of Cd and Pb pollution sources.

Abstract
Objective: To analyze the short-time efficacy of empagliflozin in the treatment of glycogen storage disease type Ⅰb (GSD Ⅰb). Methods: In this prospective open-label single-arm study, the data of 4 patients were collected from the pediatric department in Peking Union Medical College Hospital from December 2020 to December 2022. All of them were diagnosed by gene sequencing and had neutropenia. These patients received empagliflozin treatment. Their clinical symptoms such as height and weight increase, abdominal pain, diarrhea, oral ulcer, infection times, and drug applications were recorded at 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 12 months, and 15 months after treatment to assess the therapeutic effect. The liquid chromatography-tandem mass spectrometry method was used to monitor the changes in 1, 5-anhydroglucitol (1, 5AG) concentration in plasma. At the same time, adverse reactions such as hypoglycemia and urinary tract infection were closely followed up and monitored. Results: The 4 patients with GSD Ⅰb were 15, 14, 4 and 14 years old, respectively at the beginning of empagliflozin treatment, and were followed up for 15, 15, 12 and 6 months, respectively. Maintenance dose range of empagliflozin was 0.24-0.39 mg/(kg·d). The frequency of diarrhea and abdominal pain decreased in cases 2, 3, and 4 at 1, 2 and 3 months of treatment, respectively. Their height and weight increased at different degrees.The absolute count of neutrophils increased from 0.84×109, 0.50×109, 0.48×109, 0.48×109/L to 1.48×109, 3.04×109, 1.10×109, 0.73×109/L, respectively. Granulocyte colony-stimulating factor was gradually reduced in 1 patients and stopped in 3 patient. Plasma 1, 5 AG levels in 2 children were significantly decreased after administration of empagliflozin (from 46.3 mg/L to 9.6 mg/L in case 2, and from 56.1 mg/L to 15.0 mg/L in case 3). All 4 patients had no adverse reactions such as hypoglycemia, abnormal liver or kidney function, or urinary system infection. Conclusion: In short-term observation, empagliflozin can improve the symptoms of GSD Ⅰb oral ulcers, abdominal pain, diarrhea, and recurrent infection, also can alleviate neutropenia and decrease 1, 5AG concentration in plasma, with favorable safety.

Abstract
Objective: To investigate the misdiagnosis of area postrema syndrome (APS) manifesting as intractable nausea, vomiting and hiccups in neuromyelitis optic spectrum disease (NMOSD) and reduce the risk of misdiagnosis. Methods: We retrospectively analyzed data from NMOSD patients attending the Department of Neurology at the First Medical Center of PLA General Hospital between January 2019 and July 2021. SPSS25.0 was then used to analyze the manifestations, misdiagnosis, and mistreatment of APS. Results: A total of 207 patients with NMOSD were included, including 21 males and 186 females. The mean age of onset was 39±15 years (range: 5-72 years). The proportion of patients who were positive for serum aquaporin 4 antibody was 82.6% (171/207). In total, 35.7% (74/207) of the NMOSD patients experienced APS during the disease course; of these patients, 70.3% (52/74) had APS as the first symptom and 29.7% (22/74) had APS as a secondary symptom. The misdiagnosis rates for these conditions were 90.4% (47/52) and 50.0% (11/22), respectively. As the first symptom, 19.2% (10/52) of patients during APS presented only with intractable nausea, vomiting and hiccups; 80.8% (42/52) of patients experienced other neurological symptoms. The Departments of Gastroenterology and General Medicine were the departments that most frequently made the first diagnosis of APS, accounting for 54.1% and 17.6% of patients, respectively. The most common misdiagnoses related to diseases of the digestive system and the median duration of misdiagnosis was 37 days. Conclusions: APS is a common symptom of NMOSD and is associated with a high rate of misdiagnosis. Other concomitant symptoms often occur with APS. Gaining an increased awareness of this disease/syndrome, obtaining a detailed patient history, and performing physical examinations are essential if we are to reduce and avoid misdiagnosis.

Abstract
Tubular epithelial cells (TECs) play critical roles in the development of diabetic nephropathy (DN), and can activate macrophages through the secretion of exosomes. However, the mechanism(s) of TEC-exosomes in macrophage activation under DN remains unknown. By mass spectrometry, 1644 differentially expressed proteins, especially Dll4, were detected in the urine exosomes of DN patients compared with controls, which was confirmed by western blot assay. Elevated Epsin1 and Dll4/N1ICD expression was observed in kidney tissues in both DN patients and db/db mice and was positively associated with tubulointerstitial damage. Exosomes from high glucose (HG)-treated tubular cells (HK-2) with Epsin1 knockdown (KD) ameliorated macrophage activation, TNF-α and IL-6 expression, and tubulointerstitial damage in C57BL/6 mice in vivo. In an in vitro study, enriched Dll4 was confirmed in HK-2 cells stimulated with HG, which was captured by THP-1 cells and promoted M1 macrophage activation. In addition, Epsin1 modulated the content of Dll4 in TEC-exosomes stimulated with HG. TEC-exosomes with Epsin1-KD significantly inhibited N1ICD activation and iNOS expression in THP-1 cells compared to incubation with HG alone. These findings suggested that Epsin1 could modulate tubular-macrophage crosstalk in diabetic nephropathy by mediating exosomal sorting of Dll4 and Notch1 activation.

Abstract
Prevention of neointima formation is the key to improving long-term outcomes after stenting or coronary artery bypass grafting. RNA N6 -methyladenosine (m6 A) methylation has been reported to be involved in the development of various cardiovascular diseases, but whether it has a regulatory effect on neointima formation is unknown. Herein, we revealed that methyltransferase-like 3 (METTL3), the major methyltransferase of m6 A methylation, was downregulated during vascular smooth muscle cell (VSMC) proliferation and neointima formation. Knockdown of METTL3 facilitated, while overexpression of METTL3 suppressed the proliferation of human aortic smooth muscle cells (HASMCs) by arresting HASMCs at G2/M checkpoint and the phosphorylation of CDC2 (p-CDC2) was inactivated by METTL3. On the other hand, the migration and synthetic phenotype of HASMCs were enhanced by METTL3 knockdown, but inhibited by METTL3 overexpression. The protein levels of matrix metalloproteinase 2 (MMP2), MMP7 and MMP9 were reduced, while the expression level of tissue inhibitor of metalloproteinase 3 was increased in HASMCs with METTL3 overexpression. Moreover, METTL3 promoted the autophagosome formation by upregulating the expression of ATG5 (autophagy-related 5) and ATG7. Knockdown of either ATG5 or ATG7 largely reversed the regulatory effects of METTL3 overexpression on phenotypic switching of HASMCs, as evidenced by increased proliferation and migration, and predisposed to synthetic phenotype. These results indicate that METTL3 inhibits the phenotypic switching of VSMCs by positively regulating ATG5-mediated and ATG7-mediated autophagosome formation. Thus, enhancing the level of RNA m6 A or the formation of autophagosomes is the promising strategy to delay neointima formation.

Abstract
A unique ring C-expanded angucyclinone, oxemycin A (1), and seven new ring-cleavage derivatives (2-5 and 9-11) were isolated from the marine actinomycete Streptomyces pratensis KCB-132, together with eight known analogues (6-8 and 12-16). Their structures were elucidated by spectroscopic analyses, single-crystal X-ray diffractions, and NMR and ECD calculations. Among these atypical angucyclinones, compound 1 represented the first seven-membered ketoester in the angucyclinone family, which sheds light on the origin of fragmented angucyclinones with C-ring cleavage at C-12/C-12a in the Baeyer-Villiger hypothesis, such as 2-4, while the related "nonoxidized" analogues 5-8 seem to originate from a diverse pathway within the Grob fragmentation hypothesis. Additionally, we have succeeded in the challenging separation of elmenols E and F (12) into their four stereoisomers, which remained stable in aprotic solvents but rapidly racemized under protic conditions. Furthermore, the absolute configurations of LS1924 and its isomers (14 and 15) were assigned by ECD calculations for the first time. Surprisingly, these two bicyclic acetals are susceptible to hydrolysis in solution, resulting in fragmented derivatives 17 and 18 with C-ring cleavage between C-6a and C-7. Compared with ring C-modified angucyclinones, ring A-cleaved 11 was more active to multiple resistant "ESKAPE" pathogens with MIC values ranging from 4.7 to 37.5 μg/mL.

Abstract
OBJECTIVES The relationship between maternal alcohol consumption and postpartum depression (PPD) is still controversial. The objective of the present study was to assess the association between maternal alcohol consumption and the risk of developing PPD by means of a meta-analysis of cohort studies. STUDY DESIGN This was a meta-analysis. METHODS PubMed, Web of Science, Embase, Cochrane Library, China Biology Medicine disc, Chinese National Knowledge Infrastructure, Weipu, and Wanfang databases were searched up to February 4, 2021, to identify relevant studies that evaluated the association between maternal alcohol consumption and PPD. Meta-analysis was conducted using RevMan software and Stata software. Subgroup and sensitivity analyses were performed to explore the potential heterogeneity source, and Begg's funnel plots and Begg's linear regression test were conducted to assess the potential publication bias. RESULTS A total of 12 studies involving 50,377 participants were identified in our study. Overall, pregnant women who were exposed to alcohol were at a significantly greater risk of developing PPD compared with those who did not consume alcohol (odds ratio = 1.21; 95% confidence interval: 1.04-1.41; P = 0.020). CONCLUSIONS Maternal alcohol consumption is significantly associated with the risk of developing PPD. These results emphasize the necessity of enhancing health awareness, improving the public health policies and regulations concerning alcohol use, and strengthening the prevention and intervention of maternal alcohol consumption to promote maternal mental health.

Abstract
Objective: To explore the clinical effects of pulsed dye laser (PDL) dynamically combined with triamcinolone acetonide (TAC) in the treatment of keloids. Methods: A retrospectively observational study was conducted. From April 2015 to October 2020, 34 keloid patients (46 keloids) who met the inclusion criteria were admitted to Huaihe Hospital of Henan University. The patients were divided into TAC group and dynamic treatment group according to their treatment methods. There were 18 patients (26 keloids) in TAC group, including 8 males and 10 females, aged (30±12) years, who were treated with TAC injection alone. There were 16 patients (20 keloids) in dynamic treatment group, including 6 males and 10 females, aged (26±11) years, who were treated with TAC injection, PDL, or PDL combined with TAC injection according to the Vancouver scar scale (VSS) score before each treatment. Before the first treatment (hereinafter referred to as before treatment) and 12 months after the first treatment (hereinafter referred to as after treatment), the keloids were assessed by VSS, patient and observer scar assessment scale (POSAS), and the effect of keloids on the quality of life of patients was evaluated with dermatology life quality index (DLQI) scale. Twelve months after treatment, the curative effect of keloid was evaluated according to the VSS score and the effective rate was calculated. The first effective time and the cumulative times of TAC injection at the first effective time, the number of follow-up and the occurrence of adverse reactions of keloids within 12 months after treatment were recorded, and the incidence of adverse reactions was calculated. Data were statistically analyzed with paired sample t test, independent sample t test, Wilcoxon rank-sum test, Mann-Whitney U test, chi-square test, and Fisher's exact probability test. Results: The total VSS scores of patients' keloids in TAC group and dynamic treatment group 12 months after treatment were significantly lower than those before treatment (with t values of 7.53 and 8.09, respectively, P<0.01), and the total scores of pigmentation and vascularity in VSS and POSAS, the total POSAS score, and the DLQI scale score were significantly lower than those before treatment (with Z values of -3.71, -4.04, -4.21, -4.11, -3.76, -3.73, -3.92, and -3.93, respectively, P<0.01). The total scores of pigmentation and vascularity in VSS and POSAS of patients' keloids in dynamic treatment group 12 months after treatment were significantly lower than those in TAC group (with Z values of -2.03 and -2.12, respectively, P<0.05). Twelve months after treatment, the effective rate of patients' keloids in dynamic treatment group was significantly higher than that in TAC group (χ2=3.88, P<0.05). The first effective time of patients' keloids in dynamic treatment group was 5.5 (2.0, 6.0) months, which was significantly shorter than 6.0 (2.3, 10.3) months in TAC group (χ2=4.02, P<0.05). The cumulative times of TAC injection at the first effective time of patients' keloids in dynamic treatment group was 3.2±1.7, which was significantly less than 4.2±1.8 in TAC group (t=2.09, P<0.05). The number of follow-up of patients' keloids within 12 months after treatment in dynamic treatment group was significantly more than that in TAC group (t=-2.94, P<0.01), and the total incidence of adverse reactions was lower than that in TAC group but without statistically significant difference (P>0.05). Conclusions: Compared with TAC injection alone, PDL dynamically combined with TAC in the treatment of keloid can shorten the effective time, reduce the number of TAC injection, and improve the patient's compliance and clinical efficacy.

Abstract
Atramycin C (1), one new angucycline bearing an O-6 rhamnose side chain, along with one new highly hydroxylated angucyclinone emycin G (2), and ten known analogs (3-12) were isolated from the marine-derived Streptomyces sp. strain BHB-032. Their structures were assigned by spectroscopic analysis and comparison with literature data. The absolute configuration of the sugar unit of 1 was assigned as 6-O-α-l-rhamnoside, based on the analysis of the coupling constants and chemical derivatization, whereas the absolute configuration of 2 was determined by X-ray diffraction. Furthermore, the stereochemistry of saccharothrixin A (3) and SNA-8073-A (4) was established unequivocally by X-ray crystallography for the first time. Compounds 1 and 2 exhibited moderate antimicrobial activities with minimum inhibitory concentration (MIC) values ranging from 16 to 64 μg/ml.

Abstract
OBJECTIVE To evaluate the curative effect of integrated Traditional Chinese and Western Medicine on gout, and to investigate the therapy timing and exact treatment options of integrated medicine. METHODS Totally 860 patients were enrolled, including 460 patients with intermittent gout, 200 patients with active Traditional Chinese Medicine (TCM) syndrome (TCM syndrome score ≥ 6) and 200 patients with stable TCM syndrome (score < 6). They were randomly divided into intervention and control groups. The control group was treated according to Western Medicine guidelines. The intervention group was treated with integrated Traditional Chinese and Western Medicine. The efficacy of TCM syndrome, joint pain score, joint swelling score, ESR, C-reactive protein, serum uric acid, liver and kidney function, and the duration of remission of TCM syndrome were compared between the two groups before and after treatments. RESULTS For the patients with stable TCM syndrome, there was no significant difference in the effective rate and inefficiency between the intervention group and the control group. For the active type, the effective rate of the intervention group is better than the control group significantly. For the stable type, there was no significant difference between the intervention group and the control group in improving the scores of joint pain and swelling, reducing the level of ESR, C-reactive protein, serum uric acid and improving liver and kidney function. For the active type, the differences between the two groups were significant. The stable stage of gout in the intervention group was longer than the control group. CONCLUSION For the gout patients with stable TCM syndrome in the acute stage of gout, we can use TCM treatment or Western Medicine alternatively; for the patients with active TCM syndrome, the scheme of combination of Traditional Chinese and Western Medicine can be applied, with the better curative effect than any medicine alone.

Abstract
Two unique trinorlabdane diterpenoid alkaloids, forsyqinlingines A (1) and B (2), were isolated from the ripe fruits of Forsythia suspensa. Their structures, including absolute stereochemical configurations, were fully elucidated from extensive spectroscopy experiments, single-crystal X-ray diffraction, and electronic circular dichroism (ECD). In addition, a plausible biosynthetic pathway for the formation of compounds 1 and 2 in Forsythia suspensa was also proposed. In vitro, the two C17-labdane diterpenoid alkaloids exhibited anti-inflammatory activities by inhibiting the release of β-glucuronidase in rat polymorphonuclear leukocytes (PMNs), and antiviral activities against influenza A (H1N1) virus and respiratory syncytial virus (RSV). Two unique trinorlabdane diterpenoid alkaloids, forsyqinlingines A (1) and B (2), were isolated from the ripe fruits of Forsythia suspensa, and found to show significant anti-inflammatory activities and anti-viral activities.![]()

Abstract
Objective: To explore the relationship between microsurgery and prognosis of acoustic neuroma. Methods: A total of 553 acoustic neuroma surgical cases admitted to the First Affiliated Hospital of Soochow University from January 1, 1986 to September 30, 2016, were collected retrospectively. They were divided into 1986-1995 group, 1996-2005 group, and 2006-2016 group. The general information, tumor size, preoperative hospital stay, total hospital stay, operation time, intraoperative blood transfusion, use of neuroelectrophysiological monitoring, internal auditory canal wall grinding, tumor resection degree, postoperative facial nerve function rating (House-Brackmann grading), discharge status, and quality of life assessment KPS of patients were statistically analyzed. Results: Compared with the 1986-1995 group and the 1996-2005 group, the average age of patients in the 2006-2016 group ((52.9±13.3) years) was larger but the overall tumor volume ((3.7±0.8) cm) was smaller, and preoperative hospital stay ((4.9±1.9) days), the total hospital stay ((19.4±6.4) days) was significantly reduced, the operation time ((4.6±1.0) hours) was shortened, the intraoperative blood transfusion rate (18.5%) was significantly reduced, the intraoperative neuroelectrophysiological monitoring utilization rate (8.9%), and the internal auditory canal rate (12.7%) was higher. While increasing the tumor total resection and near total resection rate (89.2%), it further improved the postoperative facial nerve function retention rate (71.5%), and significantly increased the discharge cure rate (88.5%) (P<0.05). At the same time, the postoperative quality of life assessment good rate (KPS≥60 points) and excellent rate (KPS≥80 points) of the patients in the 2006-2016 group increased significantly, reaching 94.2% and 45.8% (P<0.05). Conclusion: The maturity of microsurgery techniques and the use of intraoperative neuroelectrophysiological monitoring can shorten the treatment cycle of patients with acoustic neuroma, increase the tumor resection rate and postoperative facial nerve function retention rate, and effectively improve the quality of life of patients after surgery.

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
Objective: To investigate the prognosis and risk factors of patients with anterior communicating aneurysm treated by aneurysm clipping or interventional embolization. Methods: The clinical data of 730 patients with anterior communicating aneurysm who underwent aneurysm clipping or interventional embolization in the department of neurosurgery, the first affiliated hospital of Soochow University from January 1999 to December 2018 were retrospectively analyzed. The prognosis of patients in the clipping group from 1999 to 2008 and the clipping group from 2009 to 2018, the clipping group from 2009 to 2018 and the interventional group from 2009 to 2018 were compared respectively, and the risk factors affecting the prognosis of patients were statistically analyzed. Results: The rate of poor prognosis was 32.7% in the clipping group from 1999 to 2008, 21.3% in the clipping group from 2009 to 2018, and the rate of intraoperative aneurysm rupture and postoperative cerebral infarction was lower in the clipping group from 2009 to 2018 (P<0.05). There was no significant statistical difference in the prognosis between the clipping group and the interventional group from 2009 to 2018 (P>0.05). The results of multivariate analysis showed that preoperative Hunt-Hess grade, postoperative cerebral infarction and postoperative hemorrhage were the risk factors affecting the prognosis of patients (P<0.05). Conclusion: The prognosis of patients treated by clipping from 2009 to 2018 was significantly improved compared with that from 1999 to 2008. There was no significant difference in the prognosis between the clipping group and the interventional group from 2009 to 2018. Preoperative Hunt-Hess grading, postoperative cerebral infarction and postoperative hemorrhage were independent risk factors affecting the prognosis.

Abstract
Five previously undescribed labdane diterpenoids, named Forsypensins A-E, were isolated from the fruits of Forsythia suspensa. The structures and relative configurations of the compounds were elucidated via extensive spectroscopic methods, and their absolute configurations were fully confirmed by single crystal X-ray diffraction analyses using Cu Kα radiation and electronic circular dichroism data. The five labdane diterpenoids showed in vitro anti-inflammatory activity in rat polymorphonuclear leukocytes, inhibiting the rates of β-glucuronidase release by 43.6%-49.2% at concentrations of 10 μM. The compounds also had anti-viral activity against influenza A (H1N1) virus and respiratory syncytial virus (RSV), with IC50 values in the range 21.8-27.4 μM, and EC50 values in the range 10.5-15.4 μM, respectively.

Abstract
Abstract Objective To discuss the related factors influencing the initiation time of forensic psychiatric assessment by analysis of the initiation time of forensic psychiatric assessment of criminal cases in Hunan Province. Methods Related data in assessment files of criminal cases accepted by 8 forensic psychiatric assessment institutions in Hunan Province from January 1, 2011 to December 31, 2016 were extracted. The Logistic regression analysis was used to explore the factors influencing the initiation time of forensic psychiatric assessment. After using property score matching (PSM) to control the influence of confounding factors, the efficiency of public security organs to initiate assessments of suspects with (without) mental disorders and with (without) responsibilities were compared. Results A total of 4 346 cases were included. The Logistic regression analysis suggested that the factors independently related to the initiation time of assessment include: cause of assessment, nationality of the assessed, history of diagnosis and treatment of mental illnesses, history of crimes, history of drug abuse, and status of alcohol consumption before the crime (all P<0.05). The initiation time of assessment of suspects diagnosed with mental disorder was shorter than those with none (P<0.05); the initiation time of assessment of suspects without criminal responsibility was shorter than those with responsibility (P<0.05). After using PSM to control confounding factors, the differences above still existed. Conclusion The cause of assessment, nationality of the assessed, history of diagnosis and treatment of mental illnesses, history of crimes, history of drug abuse, and status of alcohol consumption before the crime are factors that influence the efficiency of public security organs to initiate forensic psychiatric assessments. Under the current assessment initiation mode, forensic psychiatric assessment of suspects who have mental disorders, especially those with no responsibility may be given priority to initiate.

Abstract
Objective: To observe the lung injury of male rats induced by sub-chronic exposure to crotonaldehyde, and to explore the possible mechanism of injury. Methods: Forty SPF male Wistar rats were randomly divided into control group and 3 groups in each group, and each group received 0.0, 2.5, 4.5, 8.5 mg/kg body weight crotonaldehyde solution for continuous intragastric administration. 120 d, once a day. After the end of the exposure, the body weight of the rats was measured, and the lung tissues were quickly separated after cervical dislocation. The organ coefficients were calculated and histopathological examination was performed to determine malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione. Peroxidase (GSH-Px) content; ELISA was used to measure interleukin (IL) -6, IL-1β, and tumor necrosis factor (TNF) -α in lung tissues. Results: Compared with the control group, the weight gain of the rats in the 4.5 and 8.5 mg/kg exposure groups was small, and the lung weight and organ coefficient of the exposed group decreased, the difference was statistically significant (P<0.05). In the exposed group, the lung tissue structure was disordered, the alveolar wall was thickened, and inflammatory cell infiltration was observed. Compared with the control group, the MDA activity in the serum of the rats in the 4.5 mg/kg and 8.5 mg/kg groups increased, and the SOD and GSH-Px activities decreased, the difference was statistically significant (P<0.05). TNF-α levels in the lung tissues of rats exposed to 4.5 mg/kg and 8.5 mg/kg, and levels of (IL) -6 and IL-1β in the lungs of rats in the 2.5, 4.5, and 8.5 mg/kg groups. Significantly increased, the difference was statistically significant (P<0.05) . Conclusion: Crotonaldehyde may induce inflammatory and oxidative stress damage in rats by up-regulating the expression of inflammatory factors in lung tissue and changing the oxidative balance.

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
Nitrogen (N) and phosphorus (P) from non-point source (NPS) pollution in Nansi Lake Basin greatly influenced the water quality of Nansi Lake, which is the determinant factor for the success of East Route of South-North Water Transfer Project in China. This research improved Johnes export coefficient model (ECM) by developing a method to determine the export coefficients of different land use types based on the hydrological and water quality data. Taking NPS total nitrogen (TN) and total phosphorus (TP) as the study objects, this study estimated the contributions of different pollution sources and analyzed their spatial distributions based on the improved ECM. The results underlined that the method for obtaining output coefficients of land use types using hydrology and water quality data is feasible and accurate, and is suitable for the study of NPS pollution at large-scale basins. The average output structure of NPS TN from land use, rural breeding and rural life is 33.6, 25.9, and 40.5%, and the NPS TP is 31.6, 43.7, and 24.7%, respectively. Especially, dry land was the main land use source for both NPS TN and TP pollution, with the contributed proportions of 81.3 and 81.8% respectively. The counties of Zaozhuang, Tengzhou, Caoxian, Yuncheng, and Shanxian had higher contribution rates and the counties of Dingtao, Juancheng, and Caoxian had the higher load intensities for both NPS TN and TP pollution. The results of this study allowed for an improvement in the understanding of the pollution source contribution and enabled researchers and planners to focus on the most important sources and regions of NPS pollution.

Abstract
Juglonols A-C (1-3), three new juglone derivatives possessing a hydroxyethyl side chain, were isolated from an organic extract of the immature exocarps of Juglans mandshurica together with five known tetralones (4-8). Their structures were elucidated by extensive spectroscopic analyses and comparison with literature data. The new juglone derivatives exhibited inhibitory activities towards a panel of bacteria and fungi, as well as cancer cell lines. In contrast, the known tetralone homologues (4-8) appeared to be much less efficacy.

Abstract
With the aim of developing highly conductive ink for flexible electronics on heat-sensitive substrates, Ag nanospheres and nanoplates were mixed to synthesize hybrid inks. Five kinds of hybrid ink and two types of pure ink were written to square shape on Epson photo paper using rollerball pens, and sintered at a low temperature (100 °C). The microstructure, electrical resistivity, surface porosity, hardness and flexibility of silver patterns were systematically investigated and compared. It was observed that the optimal mixing ratio of nanospheres and nanoplates was 1:1, which equipped the directly written pattern with excellent electrical and mechanical properties. The electrical resistivity was 0.103 μΩ · m, only 6.5 times that of bulk silver. The enhancement compared to pure silver nanospheres or nanoplates based ink was due to the combined action of nanospheres and nanoplates. This demonstrates a valuable way to prepare Ag nanoink with good performance for printed/written electronics.

Abstract
AIM To summarize the characteristics of liver function in brucellosis patients with liver injury.
METHODS The clinical and laboratory data of 254 brucellosis patients with liver injury treated at the First Hospital of Jilin University were retrospectively evaluated.
RESULTS The age of the 254 patients ranged from 2 to 80 years. All of the patients were diagnosed according to the 2012 brucellosis guidelines. Among the 254 patients, the majority had an increase in alanine transaminase (ALT) and aspartate transaminase (AST) levels < 3 times, an increase in γ-glutamyl transferase > 3 times, slightly elevated alkaline phosphatase, and normal total bilirubin. The disease duration was shorter in the abnormal liver function group than in the normal liver function group, but the highest temperature was higher in the abnormal liver function group. All patients were treated according to the World Health Organization recommendations. The time to fever relief in the two groups had no significant difference, but white blood cells, C-reactive protein, and erythrocyte sedimentation rate were higher in patients with normal liver function than in those without. Of 31 patients with abnormal liver function who were followed, no treatment failure occurred, but five had relapse. In the 44 patients with normal liver function who were randomly followed, three had treatment failure and six had recurrence. There was no significant difference between the two groups in the recurrence rate (P = 0.764). Total bilirubin was higher in patients with viral hepatitis than in those without.
CONCLUSION Brucella infection can cause varying degrees of liver dysfunction, and ALT or AST increase is usually not more than 3 times. Occasionally, patients may develop severe liver injury, but systemic inflammatory is slight. After a short period of treatment, liver function returns to normal in most cases. Liver injury is more severe in those also having viral hepatitis.

Abstract
OBJECTIVE The aim of this study was to prospectively investigate the incidence of ventilator associated events (VAEs) in intensive care units (ICUs) among adult patients, and to evaluate the correlation between VAEs and ventilator associated pneumonia (VAP). METHODS A prospective 3-month cohort study (January 2015 to March 2015) was carried out. VAEs were divided into three groups: with ventilator-associated condition (VAC), with infection related ventilator-associated complication (IVAC) and with possible VAP (PVAP). Sensitivity and specificity of VAEs were evaluated and compared to the traditional VAP. Kappa test was applied to judge the consistency of VAC and VAP. RESULTS During Jan. 2015 and Mar. 2015, 1 014 patients were admitted to 8 ICUs, with 7 977 patients per day. In total, 197 patients used the mechanical ventilation installation, with, a total number of 3 152 ventilator-days. Finally, 1 214 ventilation days in the VAC group and 1 938 ventilation days in the non-VAC group) that were available for final analysis. 46 VAC cases were identified including 22 classified as IVAC (14.59 and 6.98 per 1 000 ventilation days, respectively). Length of ICU stay and duration on mechanical ventilation for VAC patients were both significantly longer than those for non-VAC patients (P<0.05). Sensitivity and specificity of the VAC criteria for the detection of VAP were 36.92% and 83.33%, respectively. CONCLUSION The VAEs surveillance paradigms could be applied to monitor patients on the use of mechanical ventilation installation. However, sensitivity and specificity of VAC were under pool for the diagnosis of VAP. However, automatically surveillance programs was relied on the improvement of auto-information systems.

Abstract
Chronic osteomyelitis (COM) is an infectious disease caused by methicillin-resistant Staphylococcus aureus (MRSA), the main characteristics of COM including local dead bone formation, soft tissue infection, and repeatedly attacks. As a sensitive antibiotic, vancomycin plays an important role in the therapy of COM caused by MRSA. Currently, drug treatment is divided into systemic and topical, systemic medication is given priority to intravenous drug delivery; local drug application including local delivery device and local antibiotics lavage and regional arterial perfusion. In practice, its validity depends on whether free drug concentration of vancomycin has riched the effective concentration in the organization. Nevertheless, low concentration lead to treatment failure and even induce drug-resistance bacteria, meanwhile high concentration may cause acute renal failure. So when using vancomycin for the treatment of chronic osteomyelitis, both drug resistance and renal toxicity is as the same important as the effectiveness. Systemic administration is a targeting weak way and has many complications; topical medicate effect on the lesion can be targeted, it would be an effective way in the future treatment of COM. Different methods of delivering vancomycin have great influence on local drug concentration, which makes it become the most important factor on local drug concentration of COM.

Abstract
Three green light emitting InGaN/GaN multiple quantum well (MQW) structures with different In composition grown by metal-organic chemical vapor deposition are investigated by the X-ray diffraction and the temperature-dependent photoluminescence (PL) measurements. It is found that when the In composition increases in the InGaN/GaN MQWs, the PL spectral bandwidth may anomalously decrease with increasing temperature. The reduction of PL spectral bandwidth may be ascribed to the enhanced non-radiative recombination process which may lower the light emission efficiency of the localized luminescent centers with shallow localization energy in the high-In-content InGaN quantum wells and also cause a reduction of integrated PL intensity.

Abstract
CONTEXT Cardiomyocyte apoptosis plays a critical role in the progress of heart diseases. Fucoidan, a complex-sulfated polysaccharide, has been reported to possess potential cardioprotective efficacy in vivo. OBJECTIVE The present study determines whether fucoidan could provide cardioprotection on hypoxia-induced cardiomyocyte apoptosis. MATERIALS AND METHODS H9c2 cardiomyoblast cells were incubated with various concentrations (15, 30, and 60 μg/ml) of fucoidan in a humidified incubator at 37 °C with 95% O2 and 5% CO2. After 6 h, hypoxia was processed and the cardioprotective effects of fucoidan were evaluated by applying MTT, ELISA, Hoechst 33258 nucleus staining, and western blot. RESULTS Following a 6 h exposure of H9c2 to hypoxic condition, significant reduction was found in cell survival (0.57-fold) and superoxide dismutase (SOD) activity (0.56-fold), which were associated with the increase of malondialdehyde (MDA) level (2.58-fold), creatine phosphokinase (CK, 3.57-fold), and lactate dehydrogenase (LDH) activities (2.39-fold). Moreover, hypoxia-induced apoptosis was confirmed by Hoechst 33258 nuclear staining, and these changes were accompanied by the increase of Bcl-2 (1.27-fold) and Bax expression (2.6-fold). However, preincubation of the cells with fucoidan prior to hypoxia exposure elevated the cell viability (30 μg/ml, 1.18-fold; 60 μg/ml, 1.32-fold) and SOD activity (30 μg/ml, 1.12-fold; 60 μg/ml, 1.25-fold), but decreased the MDA level (30 μg/ml, 0.70-fold; 60 μg/ml, 0.80-fold), CK (30 μg/ml, 0.69-fold; 60 μg/ml, 0.76-fold), and LDH (30 μg/ml, 0.67-fold; 60 μg/ml, 0.86-fold) leakages. Hoechst 33258 nuclear staining observations demonstrated the same protective effect of fucoidan on hypoxia-induced myocardial injury. Also, cardioprotective effects of fucoidan were reflected by increasing Bcl-2 (60 μg/ml, 1.84-fold), as well as decreasing Bax (60 μg/ml, 0.6-fold). CONCLUSION Fucoidan had protective effect against hypoxia-induced cardiomyocytes apoptosis, and the mechanism might involve protections of the cell from oxidative injury.

Abstract
We report results of numerical simulations on the various initial conditions for dark soliton generation in an all-normal-dispersion fiber laser. All the dark solitons generated are odd dark solitons. Differently from the dark soliton generation in fibers, where an arbitrary dip could evolve into a dark soliton, it is found that the dark soliton can originate only from an initial dip with a certain parameter requirement. A bright pulse with either a hyperbolic secant square, Gaussian, or Lorentz profile can be developed into a dark soliton, provided that the parameters of the initial bright pulse are selected. Dark solitons can be generated in fiber lasers only if there is a phase jump, and this phase jump can be maintained and evolve to π during the pulse evolution.

Abstract
Interferon regulatory factor 9 (IRF9) has various biological functions and regulates cell survival; however, its role in vascular biology has not been explored. Here we demonstrate a critical role for IRF9 in mediating neointima formation following vascular injury. Notably, in mice, IRF9 ablation inhibits the proliferation and migration of vascular smooth muscle cells (VSMCs) and attenuates intimal thickening in response to injury, whereas IRF9 gain-of-function promotes VSMC proliferation and migration, which aggravates arterial narrowing. Mechanistically, we show that the transcription of the neointima formation modulator SIRT1 is directly inhibited by IRF9. Importantly, genetic manipulation of SIRT1 in smooth muscle cells or pharmacological modulation of SIRT1 activity largely reverses the neointima-forming effect of IRF9. Together, our findings suggest that IRF9 is a vascular injury-response molecule that promotes VSMC proliferation and implicate a hitherto unrecognized 'IRF9-SIRT1 axis' in vasculoproliferative pathology modulation.

Abstract
Background Interferon regulatory factor 7 (IRF7), a member of the interferon regulatory factor family, plays important roles in innate immunity and immune cell differentiation. However, the role of IRF7 in neointima formation is currently unknown. Methods and Results Significant decreases in IRF7 expression were observed in vascular smooth muscle cells (VSMCs) following carotid artery injury in vivo and platelet‐derived growth factor‐BB (PDGF‐BB) stimulation in vitro. Compared with non‐transgenic (NTG) controls, SMC‐specific IRF7 transgenic (IRF7‐TG) mice displayed reduced neointima formation and VSMC proliferation in response to carotid injury, whereas a global knockout of IRF7 (IRF7‐KO) resulted in the opposite effect. Notably, a novel IRF7‐KO rat strain was successfully generated and used to further confirm the effects of IRF7 deletion on the acceleration of intimal hyperplasia based on a balloon injury‐induced vascular lesion model. Mechanistically, IRF7's inhibition of carotid thickening and the expression of VSMC proliferation markers was dependent on the interaction of IRF7 with activating transcription factor 3 (ATF3) and its downstream target, proliferating cell nuclear antigen (PCNA). The evidence that IRF7/ATF3‐double‐TG (DTG) and IRF7/ATF3‐double‐KO (DKO) mice abolished the regulatory effects exhibited by the IRF7‐TG and IRF7‐KO mice, respectively, validated the underlying molecular events of IRF7‐ATF3 interaction. Conclusions These findings demonstrated that IRF7 modulated VSMC proliferation and neointima formation by interacting with ATF3, thereby inhibiting the ATF3‐mediated induction of PCNA transcription. The results of this study indicate that IRF7 is a novel modulator of neointima formation and VSMC proliferation and may represent a promising target for vascular disease therapy.

Abstract
InGaN-based blue-violet laser diodes (LDs) suffer from electron leakage into the p-type regions, which could be only partially alleviated by employing the electron blocking layer (EBL). Here, a thin undoped InGaN interlayer prior to EBL is proposed to create an additional forbidden energy range above the natural conduction band edge, which further suppresses the electron leakage and thus improve the characteristics of LDs. Numerical device simulations reveal that when the proper composition and thickness of InGaN interlayer are chosen, the electron leakage could be efficiently eliminated without inducing any severe accumulation of electrons at the interlayer, resulting in a maximum output power of the device.

Abstract
UNLABELLED Obesity and related metabolic diseases associated with chronic low-grade inflammation greatly compromise human health. Previous observations on the roles of interferon regulatory factors (IRFs) in the regulation of metabolism prompted investigation of the involvement of a key family member, IRF3, in metabolic disorders. IRF3 expression in the liver is decreased in animals with diet-induced and genetic obesity. The global knockout (KO) of IRF3 significantly promotes chronic high-fat diet (HFD)-induced hepatic insulin resistance and steatosis; in contrast, adenoviral-mediated hepatic IRF3 overexpression preserves glucose and lipid homeostasis. Furthermore, systemic and hepatic inflammation, which is increased in IRF3 KO mice, is attenuated by the overexpression of hepatic IRF3. Importantly, inhibitor of nuclear factor kappa B kinase beta subunit / nuclear factor kappa B (IKKβ/NF-κB) signaling is repressed by IRF3, and hepatic overexpression of the inhibitor of κB-α (IκBα) reverses HFD-induced insulin resistance and steatosis in IRF3 KO mice. Mechanistically, IRF3 interacts with the kinase domain of IKKβ in the cytoplasm and inhibits its downstream signaling. Moreover, deletion of the region of IRF3 responsible for the IRF3/IKKβ interaction inhibits the capacity of IRF3 to preserve glucose and lipid homeostasis. CONCLUSION IRF3 interacts with IKKβ in the cytoplasm to inhibit IKKβ/NF-κB signaling, thus alleviating hepatic inflammation, insulin resistance, and hepatic steatosis.

Abstract
Pathological cardiac hypertrophy is a major risk factor for heart failure. In this study, we identified interferon regulatory factor 9 (IRF9), a member of the IRF family, as a previously unidentified negative regulator of cardiac hypertrophy. The level of IRF9 expression was remarkably elevated in the hearts from animals with aortic banding-induced cardiac hypertrophy. IRF9-deficient mice exhibited pronounced cardiac hypertrophy after pressure overload, as demonstrated by increased cardiomyocyte size, extensive fibrosis, reduced cardiac function, and enhanced expression of hypertrophy markers, whereas transgenic mice with cardiac-specific overexpression of murine IRF9 exhibited a significant reduction in the hypertrophic response. Mechanistically, IRF9 competes with p300 for binding to the transcription activation domain of myocardin, a coactivator of serum response factor (SRF). This interaction markedly suppresses the transcriptional activity of myocardin because IRF9 overexpression strongly inhibits the ability of myocardin to activate CArG box-dependent reporters. These results provide compelling evidence that IRF9 inhibits the development of cardiac hypertrophy by suppressing the transcriptional activity of myocardin in the heart.

Abstract
The aim of this study was to analyze the clinical significance of reversion-inducing-cysteine-rich protein with Kazal motifs (RECK) promoter methylation in pancreatic ductal adenocarcinoma (PDA). Methylation-specific polymerase chain reaction was used to examine the promoter methylation status of RECK in 60 pairs of PDA tissue samples and adjacent non-cancerous tissue samples. Statistical analyses were applied to test the associations between RECK promoter methylation status, clinicopathologic factors, and prognosis. The rate of RECK promoter methylation was significantly higher in PDA tissues than in adjacent non-cancerous tissues (P < 0.001). RECK methylation status was significantly associated with clinical stage (P = 0.017), histological differentiation (P = 0.046), and lymph node metastasis (P = 0.003), but was not associated with gender, age, and tumor location (all P > 0.05). Additionally, RECK promoter methylation is associated with malignant behavior and poor prognosis. In conclusion, determination of RECK promoter methylation status in tumor tissues may assist in the identification of patients who require aggressive postoperative intervention in order to improve prognosis.

Abstract
IRF4, a member of the interferon regulatory factor (IRF) family, was previously shown to be restricted in the immune system and involved in the differentiation of immune cells. However, we interestingly observed that IRF4 was also highly expressed in both human and animal hearts. Given that several transcription factors have been shown to regulate the pathological cardiac hypertrophy, we then ask whether IRF4, as a new transcription factor, plays a critical role in pressure overload-elicited cardiac remodeling. A transgenic mouse model with cardiac-specific overexpression of IRF4 was generated and subjected to an aortic banding for 4 to 8 weeks. Our results demonstrated that overexpression of IRF4 aggravated pressure overload-triggered cardiac hypertrophy, fibrosis, and dysfunction. Conversely, IRF4 knockout mice showed an attenuated hypertrophic response to chronic pressure overload. Mechanistically, we discovered that the expression and activation of cAMP response element-binding protein (CREB) were significantly increased in IRF4-overexpressing hearts, while being greatly reduced in IRF4-KO hearts on aortic banding, compared with control hearts, respectively. Similar results were observed in ex vivo cultured neonatal rat cardiomyocytes on the treatment with angiotensin II. Inactivation of CREB by dominant-negative mutation (dnCREB) offset the IRF4-mediated hypertrophic response in angiotensin II-treated myocytes. Furthermore, we identified that the promoter region of CREB contains 3 IRF4 binding sites. Altogether, these data indicate that IRF4 functions as a necessary modulator of hypertrophic response by activating the transcription of CREB in hearts. Thus, our study suggests that IRF4 might be a novel target for the treatment of pathological cardiac hypertrophy and failure.

Abstract
Interferon regulatory factor (IRF) 3, a member of the highly conserved IRF family transcription factors, plays a pivotal role in innate immune response, apoptosis, and oncogenesis. Recent studies have implicated IRF3 in a wide range of host defense. However, whether IRF3 induces defensive responses to hypertrophic stresses such as biomechanical stress and neurohumoral factors remains unclear. Herein, we employed an IRF3-deficient mouse model, cardiac-specific IRF3-overexpression mouse model and isolated cardiomyocytes to investigate the role of IRF3 in cardiac hypertrophy induced by aortic banding (AB) or isoproterenol (ISO). The extent of cardiac hypertrophy was quantitated by echocardiography as well as by pathological and molecular analysis. Our results demonstrate that IRF3 deficiency profoundly exacerbated cardiac hypertrophy, whereas overexpression of IRF3 in the heart significantly blunted pathological cardiac remodeling induced by pressure overload. Similar results were also observed in cultured cardiomyocytes upon the treatment with ISO. Mechanistically, we discovered that IRF3 interacted with ERK2 and thereby inhibited the ERK1/2 signaling. Furthermore, inactivation of ERK1/2 by U0126 offset the IRF3-deficient-mediated hypertrophic response induced by aortic banding. Altogether, these data demonstrate that IRF3 plays a protective role in AB-induced hypertrophic response by inactivating ERK1/2 in the heart. Therefore, IRF3 could be a new target for the prevention and therapy of cardiac hypertrophy and failure.
