Objective: to investigate the effect and side effects of recombinant human interleukin - 11 (rhIL - 11, in Chinese Juheli, produced by Qi Lu Biotechnology CO., LTD) in the second prevention of chemotherapy induced thrombocytopenia (CIT). Methods: Cancer patients with CIT were recruited and were treated with rhIL - 11 (treatment phase, TP), and in the following cycle, all these patients administered with rhIL - 11 24 hours immediately after chemotherapy (preventive treatment phase, PTP). Duration and severity of thrombocytopenia between two phases were compared. Results: for patients in TP or PTP, nadir values of platelet were ($29.28{\pm}20.08){\times}10^9/L$ and ($45.24{\pm}19.66){\times}10^9/L$, duration of thrombocytopenia in TP and PTP was ($11.52{\pm}4.33$) and ($8.20{\pm}+2.77$)days, recovery time was ($19.40{\pm}3.89$)and ($13.44{\pm}3.02$)days, duration of rhIL - 11 administration was ($10.68{\pm}2.46$)and ($6.28{\pm}1.77$)days, number of patients needing platelet infusion was 16and4 respectively, all differences were statistically significant (p value were 0.007, 0.002, 0.000, 0.000, 0.034 respectively). For TP and PTP, number of patients with hemorrhage was 8 and 4, duration of bleeding was ($5.00{\pm}0.82$) and ($4.50{\pm}0.71$) days respectively, with no statistically significant difference. Adverse reactions mainly included fever, edema, arrhythmia, joint pain, fatigue, skin rash, headache, dizziness, etc., all were not statistically significant between TP and PTP. Conclusion: rhIL - 11 could be well tolerated and is effective that could reduce the duration, severity of CIT, platelet transfusion, and incidence of bleeding, as well as shorten the recovery time, duration of rhIL - 11 administration. Thus, rhIL - 11 could be commended in the second prevention of CIT for patients with cancer.

Apolipoprotein B plays a central role in lipoprotein metabolism. Many studies have evaluated the association between Apolipoprotein B gene polymorphisms (XbaI, EcoRI, SpIns/Del, MspI) and the risk for coronary artery disease and myocardial infarction. However, the results remain inconsistent, particularly among different populations. To more precisely determine the association between Apolipoprotein B gene polymorphisms and coronary artery disease/myocardial infarction risk, we performed a meta-analysis via a comprehensive search of electronic databases (up to February 1st, 2015), odds ratios (OR) and 95 % confidence intervals were calculated using a fixed or random effect model. A total of 47 studies, with 9411 coronary artery disease/myocardial infarction cases and 9082 controls, were included in this meta-analysis. The combined results revealed significant associations between an increased risk of coronary artery disease/myocardial infarction and EcoRI (AA vs GG: OR 1.511, 95 % confidence interval (CI) 1.098, 2.078) and SpIns/Del (DD vs II: OR 1.331, 95 % CI 1.064, 1.665) alleles in the general population. In a subgroup analysis stratified by ethnicity, the T allele of the XbaI variant was associated with a decreased risk in Caucasians, whereas it was associated with an increased risk among the East Asian population. No significant correlation was detected between the A allele of the MspI variant and the coronary artery disease/myocardial infarction risk in either the general population or any ethnic subgroup. The results of our study suggest that Apolipoprotein B gene polymorphisms may affect the coronary artery disease/myocardial infarction susceptibility and these effects may display notable discrepancies among different populations.

Purpose This study was aimed to investigate long-term survivals and toxicities of early-stage nasopharyngeal carcinoma (NPC) in endemic area, evaluating the role of chemotherapy in stage II patients. Materials and Methods Totally 187 patients with newly diagnosed NPC and restaged American Joint Committee on Cancer/ International Union Against Cancer 8th T1-2N0-1M0 were retrospectively recruited. All received intensity-modulated radiotherapy (IMRT)±chemotherapy (CT) from 2001 to 2010. Results With 15.7-year median follow-up, 10-year locoregional recurrence-free survival, distant metastasis-free survival (DMFS), disease-specific survival (DSS), and overall survival (OS) were 93.3%, 93.5%, 92.9% and 88.2%, respectively. Multivariable analyses showed cervical lymph nodes positive and pre-treatment prognostic nutritional index ≥ 52.0 could independently predict DMFS (p=0.036 and p=0.011), DSS (p=0.014 and p=0.026), and OS (p=0.002 and p < 0.001); Charlson comorbidity index < 3 points could predict DSS (p=0.011); age > 45 years (p=0.002) and pre-treatment lactate dehydrogenase ≥ 240 U/L (p < 0.001) predicted OS. No grade 4 late toxicity happened; grade 3 late toxicities included subcutaneous fibrosis (4.3%), deafness or otitis (4.8%), skin dystrophy (2.1%), and xerostomia (1.1%). No differences on survivals were shown between IMRT+CT vs. IMRT alone in stage II patients, even in T2N1M0 (p > 0.05). Unsurprising, patients in IMRT+CT had more acute gastrointestinal reaction, myelosuppression, mucositis, late ear toxicity, and cranial nerve injury (all p < 0.05) than IMRT alone group. Conclusion Superior tumor control and satisfying long-term outcomes could be achieved with IMRT in early-stage NPC with mild late toxicities. As CT would bring more toxicities, it should be carefully performed to stage II patients.

Xylanase inhibitors are known to play important roles in response to fungal pathogens attack. WRKY transcription factors are also involved in plant defence against pathogens. However, whether WRKY transcription factors interacting with rice xylanase inhibitor RIXI remains unknown. 13 W-boxes, binding sites for WRKY transcription factors were found in RIXI promoter sequence of rice by analyzing RIXI promoter. ChIP-PCR analysis and dual luciferase reporter system assay were used to identify interaction between xylanase inhibitor RIXI and WRKY transcription factors. Results showed OsWRKY6 and OsWRKY46 directly bound to RIXI promoter and regulated RIXI expression diferently. Over-expressing OsWRKY6 and OsWRKY46 transgenic plants were achieved, and OsWRKY6 and OsWRKY46 overexpressed transgenic lines showed higher expression levels of RIXI and higher resistance to Magnaporthe oryzae G11 (M. oryzae G11) compared to wild type (WT). Increased RIXI expression in OsWRKY6 and OsWRKY46 overexpressed transgenic lines was accompanied by up-regulation of pathogenesis-related genes (PR genes). Moreover, higher levels of H2O2 and higher activities of antioxidant enzymes were found in transgenic lines compared to WT plants. Results indicated that over-expression of OsWRKY6 and OsWRKY46 in transgenic lines maybe enhanced rice disease resistance by regulating RIXI expression.

Modular multilevel converter–bidirectional DC–DC converter (MMC–BDC) is a prospective solution for the bidirectional DC–DC power conversion between medium-voltage DC (MVDC) bus and distributed energy storage system. Researchers have studied its application in the shipboard power system. In face of distributed energy storage devices with discrepant state of charge (SOC), the sub-modules (SMs) of MMC–BDC should work under inconsistent power to unify the SOC level. The existing unbalanced SM power control strategies fail to consider unbalanced operation range and efficiency. Therefore, this study proposes a novel unbalanced control strategy based on the feedforward compensation method, which is characterized by inconsistent SM voltage. Comparisons are made to demonstrate the advantages of the proposed strategy over traditional ones, and the dynamic characteristics are analyzed. Simulation and experiment results illustrate the effectiveness of the proposed unbalanced operation strategy.

Mitochondria are highly dynamic organelles that constantly undergo fission and fusion processes that closely related to their function. Disruption of mitochondrial dynamics has been demonstrated in acute kidney injury (AKI), which could eventually result in cell injury and death. Previously, we reported that augmenter of liver regeneration (ALR) alleviates renal tubular epithelial cell injury. Here, we gained further insights into whether the renoprotective roles of ALR are associated with mitochondrial dynamics. Changes in mitochondrial dynamics were examined in experimental models of renal ischemia-reperfusion (IR). In a model of hypoxia-reoxygenation (HR) injury in vitro, dynamin-related protein 1 (Drp1) and mitochondrial fission process protein 1 (MTFP1), two key proteins of mitochondrial fission, were downregulated in the Lv-ALR + HR group. ALR overexpression additionally had an impact on phosphorylation of Drp1 Ser637 during AKI. The inner membrane fusion protein, Optic Atrophy 1 (OPA1), was significantly increased whereas levels of outer membrane fusion proteins Mitofusin-1 and -2 (Mfn1, Mfn2) were not affected in the Lv-ALR + HR group, compared with the control group. Furthermore, the mTOR/4E-BP1 signaling pathway was highly activated in the Lv-ALR + HR group. ALR overexpression led to suppression of HR-induced apoptosis. Our collective findings indicate that ALR gene transfection alleviates mitochondrial injury, possibly through inhibiting fission and promoting fusion of the mitochondrial inner membrane, both of which contribute to reduction of HK-2 cell apoptosis. Additionally, fission processes are potentially mediated by promoting tubular cell survival through activating the mTOR/4E-BP1 signaling pathway.

MicroRNAs (miRNAs) are a family of non-coding RNA that are able to adjust the expression of many proteins, including ATP-binding cassette transporter and organic cation transporter. We sought to evaluate the effect of miR-511 on the regulation of OATP1B1 expression by free fatty acids. When using free fatty acids to stimulate Chang liver cells, we found that the expression of miR-511 increased significantly while the expression of OATP1B1 decreased. We also proved that SLCO1B1 is the target gene of miR-511 with a bioinformatics analysis and using the dual luciferase reporter assay. Furthermore, the expressions of SLCO1B1 and OATP1B1 decreased if transfecting Chang liver cells with miR-511, but did not increase when transfecting the inhibitors of miR-511 into steatosis cells. Our study indicates that miR-511 may play an important role in the regulation of OATP1B1 expression by free fatty acids.
