    Abstract: Objective: The mechanism of CD4 + T-cell dysfunction in systemic lupus erythematosus (SLE) has not been fully understood. Increasing evidence show that long noncoding RNAs (lncRNAs) can regulate immune responses and take part in some autoimmune diseases, while little is known about the lncRNA expression and function in CD4 + T of SLE. Here, we aimed to detect the expression profile of lncRNAs in lupus CD4 + T cells and explore the mechanism that how lincRNA00892 in CD4 + T cells is involved in the pathogenesis of SLE. Methods: The expression profiles of lncRNAs and mRNAs in CD4 + T cells from SLE patients and healthy controls were detected by microarray. LincRNA00892 and CD40L were chosen for validation by quantitative real-time PCR (qRT-PCR). Coexpression network was conducted to predict the potential target genes of lincRNA00892. Then lincRNA00892 was overexpressed in normal CD4 + T cells via lentivirus transfection. The expression of lincRNA00892 was detected by qRT-PCR. The expression of CD40L was detected by qRT-PCR, western blotting, and flow cytometry, respectively. The expression of CD69 and CD23 was measured by flow cytometry. The secretion of IgG was determined by enzyme-linked immunosorbent assay (ELISA). The proteins targeted by lincRNA00892 were measured by RNA pulldown and subsequent mass spectrometry (MS). The interaction between heterogeneous nuclear ribonucleoprotein K (hnRNP K) and lincRNA00892 or CD40L was detected by RNA immunoprecipitation (RIP) assay. Results: A total of 1887 lncRNAs and 3375 mRNAs were found to be aberrantly expressed in CD4 + T cells of SLE patients compared to healthy controls. LincRNA00892 and CD40L were confirmed to be upregulated in CD4 + T cells of SLE patients by qRT-PCR. The lncRNA–mRNA coexpression network analysis indicated that CD40L was a potential target of lincRNA00892. Overexpression of lincRNA00892 enhanced CD40L protein levels while exerting little influence on CD40L mRNA levels in CD4 + T cells. In addition, lincRNA00892 could induce the activation of CD4 + T cells. Furthermore, lincRNA00892 led to the activation of B cells and subsequent secretion of IgG in a CD4 + T-cell–dependent manner. Finally, hnRNP K was found to be among the proteins pulled down by lincRNA00892, and hnRNP K could bind to lincRNA00892 or CD40L directly. Conclusion: Our results showed that the lncRNA expression profile was altered in CD4 + T cells of SLE. LincRNA00892 possibly contributed to the pathogenesis of SLE by targeting hnRNP K and subsequently upregulating CD40L expression to activate CD4 + T and B cells. These provided us a potential target for further mechanistic studies of SLE pathogenesis.

    Abstract: Background & Aims: The high expression levels of interferon-γ (IFN-γ)-inducible genes correlate positively with liver diseases. The present study aimed to explore the effect of isoliquiritigenin (ISL) on the expression of genes induced by IFN-γ in vitro, and to elucidate the underlying molecular mechanisms. Methods: HepG2 and L02 cells were divided into control, ISL, IFN-γ, and IFN-γ plus ISL groups. The cytotoxicity of compounds to cells was evaluated by Cell Counting Kit 8 (CCK8) assay; the expression levels of chemokine (C-X-C motif) ligand 9 (CXCL9), CXCL10, CXCL11, and interleukin-6 (IL-6) in cells and supernatant were measured by quantitative real time polymerase chain reaction (qRT-PCR) and ELISA, respectively. Moreover, western blot was used to examine the phosphorylated levels of janus kinase (JAK)/signal transducer and activator of transcription 1 (STAT1), nuclear factor (NF)-γB, interferon regulatory factor 3 (IRF3)/myeloid differentiation factor 88 (MyD88), mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K)/Protein Kinase B (Akt) in HepG2 and L02 cells exposed to ISL, IFN-γ and IFN-γ plus ISL. Results: The results showed that IFN-γ treatment induced the expression of CXCL9, CXCL10, CXCL11, and IL-6 in HepG2 and LO2 cells, which could be significantly and dose-dependently inhibited by ISL treatment (P 〈 0.05 or P 〈 0.01), but the inhibitory effect of ISL on IL-6 expression was not so good as on CXCL9, CXCL10, and CXCL11 expression. Furthermore, ISL treatment dose-dependently inhibited the activation of JAK1/STAT1, IRF3/MyD88, extracellular signal-regulated kinase (ERK)/MAPK, c-Jun N-terminal kinase (JNK)/MAPK, and PI3K/Akt signaling pathways (P 〈 0.05), but had no effect on the activation of JAK2/STAT1, NF-γB and p38/MAPK signaling pathways. Conclusion: We demonstrate that ISL inhibits IFN-γ-induced inflammation in hepatocytes via influencing the activation of JAK1/STAT1, IRF3/MyD88, ERK/MAPK, JNK/MAPK, and PI3K/Akt signaling pathways.

    Abstract: Background: Lipocalin 2 (LCN2), a protein primarily produced by hepatocytes, is highly upregulated under various conditions that induce cellular stress, such as intoxication, infection or inflammation. However, the precise biological functions and underlying mechanisms of LCN2 in hepatocytes remains unknown. Methods: Hepatocyte stress was successfully induced by treating Huh7 cells with interleukin-1β (IL-1β). Interleukin-6 (IL-6), Tumor Necrosis Factor-α (TNF-α) and LCN2 levels were measured in IL-1β treated Huh7 cells and supernatant. Additionally, microarray analysis was conducted to identify genes differentially expressed in LCN2-silenced and control Huh7 cells. Results: TNF-α, IL-6 and LCN2 were significantly elevated in Huh7 cells after IL-1β) treatment. In LCN2-silenced Huh7 cells, expression of IL-6 and TNF-α was significantly increased when compared with the expression levels of control Huh7 cells. Furthermore, differentially expressed genes were observed between the LCN2-silenced and control cells. Microarray analysis indicated that LCN2 acted by influencing genes involved in protein metabolism, stress response, cell cycle and proliferation. Conclusions: Our results suggest that LCN2 upregulation protects hepatocytes from IL-1β-induced stress. Additionally, our microarray analysis of LCN2-silenced and control cells provides a better understanding of the mechanisms that may be influenced by LCN2 induction.

    Abstract: Supercritical fluid chromatography (SFC), operated in conventional mode, is normally recognized as normal phase chromatography, and uses a solvent combination of supercritical CO 2 and alcohols to separate compounds. Hexane, a commonly used solvent in normal phase liquid chromatography (NP‐LC), is rarely used in SFC and, in some cases, is added to the organic modifiers to increase liquid content in order to achieve better efficiency in preparative SFC for poorly retained compounds. Although hexane is believed to have similar solvent strength to that of supercritical CO 2 , its effects on the enantioseparation in SFC is largely unknown. To understand the chromatographic effects of an apolar solvent, such as hexane in SFC, we compared the chromatographic behaviors of 35 chiral compounds using a parallel SFC method under traditional SFC mode of only “pure” alcohol‐CO 2 to that of hexane‐assisted SFC (HA‐SFC), which uses mixtures of alcohol and hexane (as cosolvents) and CO 2 . We observed that, in some cases, hexane behaves just like supercritical CO 2 , where replacement of a portion of CO 2 with hexane does not significantly change retention times or resolution of the peaks. In many cases, however, addition of hexane in mobile phases does affect chromatographic behavior of one or both enantiomers. Such effects might provide opportunities for separation of some enantiomers. Chirality 28:192–198, 2016 . © 2016 Wiley Periodicals, Inc.

    Abstract: Objective: To evaluate the efficacy and safety of Hengli ® Chinese botulinum toxin type A (BTX-A; 100 U) in Chinese patients with overactive bladder. Methods: This study was a multicenter, randomized, double-blind, placebo-controlled trial in Chinese patients who were inadequately managed with anticholinergic medications. Eligible patients were randomized 2:1 to receive intradetrusor injections of Hengli ® BTX-A ( n = 144) or placebo ( n = 72). The primary endpoint was the change in the number of daily micturition episodes at week 6 from baseline. The secondary efficacy endpoints included the average frequency of urgency and urinary incontinence (UI) episodes per day, urgency score, average micturition volume per day, OABSS, and QoL score. Results: In the Hengli ® BTX-A group, there was a significantly greater reduction in the average number of micturition episodes per 24 h compared with the placebo group (3.28 vs. 1.43; p = 0.003). Moreover, there was a significantly greater improvement in the daily number of urgency episodes, micturition volume and OABSS score. An increased post-void residual urine volume, dysuria, and urinary tract infection represented adverse events (AEs) in the Hengli ® BTX-A group. Most AEs were mild or moderate in severity. One patient in the BTX-A group initiated clean intermittent catheterization (CIC) during treatment. Conclusion: Hengli ® BTX-A treatment was well-tolerated and resulted in significant improvements in OAB symptoms among Chinese patients inadequately managed by anticholinergics.

    Abstract: The Platelet Inhibition and Patient Outcomes (PLATO) study found that ticagrelor plus aspirin (TA) was more effective than clopidogrel plus aspirin (CA), without an increase in the risk of massive bleeding in patients undergoing percutaneous coronary intervention (PCI). Data from other studies indicate that the conclusion is controversial with the results obtained by PLATO. Aim: To investigate the efficacy and safety of TA, compared with CA, in patients with acute coronary syndrome (ACS) after PCI. Methods: A systematic literature search was performed in the MEDLINE, EMBASE, and Cochrane databases to compare the efficacy and safety of CA and TA treatment in patients with ACS after PCI. The endpoints were major adverse cardiac events (MACEs), death, stroke, myocardial infarction (MI), stent thrombosis, and bleeding events. The data analysis was performed using RevMan 5.3 software, and the odds ratios (ORs) and their 95% confidence intervals (CI) were calculated. The standards of reporting were in accordance with the PRISMA guidelines. Results: 13 studies with a total of 58,062 patients were included in this study with a subgroup analysis of the European/American and Asian populations. In terms of effectiveness for MACEs, the European, American and Asian populations benefitted more from the TA treatment than the CA treatment (European and American populations, OR = 0.82, P = 0.0002; Asian, OR = 0.66, P 〈 0.0001; total, OR = 0.78, P 〈 0.0001). In terms of specific effectiveness indicators, such as stroke, MI, and stent thrombosis, the results of TA and CA groups in the European, American, and Asian populations were not consistent. In terms of safety, there was no statistical difference in total bleeding events between TA and CA treatments (OR = 1.19, P = 0.21). However, in the Asian population, the incidence of total bleeding events (OR = 1.52, P = 0.0004) in the TA group was higher than that in the CA group. Conclusion: The TA treatment in the European and American populations is more beneficial and safer than CA treatment. However, although the Asian population has this benefit, the risk of bleeding is significantly increased as well, and antiplatelet drugs should be chosen carefully.
