Abstract
Objective: To investigate the clinical significance of accurate assessment of "volume and quality" of functional liver in Autologous liver transplantation (ALT) in the treatment of the advanced hepatic alveolar echinococcosis (HAE). Methods: The clinical data of 12 patients with advanced HAE who underwent ALT at the First Affiliated Hospital of Xinjiang Medical University from May 2015 to July 2016 were retrospectively analyzed. Results: The preoperative hepatic functions of 12 patients were 8 Child-Pugh Grade A, 1 Grade B, and 3 Grade C. Three of the patients had moderate or severe jaundice. Three of the patients calculated functional liver graft volume (GV) and standard liver volume (SLV) ratio (GV/SLV) were <30%. After the protection of liver function, anti-infection, percutaneous transhepatic cholangiography drainage (PTCD), selective portal vein embolization (PVE), and staging liver resection, liver function Child-Pugh grade of 11 patients was raised to A grade, and the other patient was B grade, meanwhile the bilirubin was reduced to 2 times the normal value. The GV/SLV ratios of 3 patients with low GV/SLV ratio had reached 44.4%, 47.2% and 56.2% respectively. In this study, the GV/SLV ratios of the 12 patients were between 73.2% and 40.8% with an average of 55.6%. Operation time was 11.5-20.5 h, with an average of 12.3 h. Anhepatic phase time was 193-375 min with median 253.5 min. The red blood cell suspension was 0-6 U during the operation. The average hospitalization was 10-42 d, with the average 22.7 d. Total hospital costs were 121 600-434 800 Yuan, with the median cost of 174 400 Yuan. One patient died of septic shock a week after surgery. Conclusion: (1)ALT may provide feasibility for the advanced HAE. (2)Accurate assessment of functional liver "volume and quality" appeared as the key points to the ALT. (3)Precise surgery and individualized treatment could improve and protect the functional liver "volume and quality" .

Abstract
Mercury (Hg) represents a ubiquitous environmental heavy metal that could lead to severe toxic effects in a variety of organs usually at a low level. The present study focused on the liver oxidative stress, one of the most important roles playing in Hg hepatotoxicity, by evaluation of different concentrations of mercuric chloride (HgCl2) administration. Moreover, the protective potential of curcumin against Hg hepatotoxic effects was also investigated. Eighty-four rats were randomly divided into six groups for a three-days experiment: control, dimethyl sulfoxide control, HgCl2 treatment (0.6, 1.2, and 2.4 mg kg-1 day-1), and curcumin pretreatment (100 mg kg-1 day-1) groups. Exposure of HgCl2 resulted in acute dose-dependent hepatotoxic effects. Administration of 2.4 mg kg-1 HgCl2 significantly elevated total Hg, nonprotein sulfhydryl, reactive oxygen species formation, malondialdehyde, apoptosis levels, serum lactate dehydrogenase, and alanine transaminase activities, with an impairment of superoxide dismutase and glutathione peroxidase in the liver. Moreover, HgCl2 treatment activated nuclear factor-E2-related factor 2-antioxidant response element (Nrf2-ARE) signaling pathway in further investigation, with a significant upregulation of Nrf2, heme oxygenase-1, and γ-glutamylcysteine synthetase heavy subunit expression, relative to control. Pretreatment with curcumin obviously prevented HgCl2-induced liver oxidative stress, which may be due to its free radical scavenging or Nrf2-ARE pathway-inducing properties. Taking together these data suggest that curcumin counteracts HgCl2 hepatotoxicity through antagonizing liver oxidative stress.

Abstract
OBJECTIVE Naturally acquired anti-hepatitis E virus (HEV) immunity can protect against new HEV infections. The aim of this study was to analyse the persistence of naturally acquired anti-HEV immunoglobulin (Ig) G and anti-HEV IgG concentrations after vaccination. METHODS We examined the seropositivity rates of participants included in a phase 3 clinical efficacy trial (67 months' follow-up) for a HEV vaccine (Hecolin; Xiamen Innovax Biotech, China) and predicted long-term persistence using mixed-effect models. RESULTS The analysis focused on 2242 baseline seropositive participants in a control group (placebo recipients) and 2031 baseline seropositive participants in an vaccine group (vaccine recipients) who received 1 to 3 doses of Hecolin. Naturally acquired anti-HEV IgG levels decreased steadily independent of the initial antibody level; 50% of the placebo recipients were expected to have undetectable antibody concentrations after 14.5 years. After immunization with Hecolin, the power-law model and the modified power-law model predicted that 82.1 and 99.4% of the participants, respectively, would remain seropositive for anti-HEV IgG for 30 years after vaccination. CONCLUSIONS Whereas naturally acquired anti-HEV IgG levels decrease steadily, HEV vaccination induces long-lasting, high-level anti-HEV IgG concentrations.

Abstract
Bacterial sexually transmitted infections including Chlamydia trachomatis and Neisseria gonorrhoeae remain an important public health concern. We aimed to assess the population-based incidence of C. trachomatis and N. gonorrhoeae in an age-standardized cohort over time. A retrospective study of a large Canadian health region was undertaken between 2010 and 2015 using linked census and digital laboratory data. C. trachomatis and N. gonorrhoeae tests were linked to patient data. Sex and age-standardized incidence rates (IR) and ratios (IRR) were calculated for cases and testing rates. The annual mean population was 1,150,556 individuals (50.1% female). A total of 15,109 cases of chlamydia and 981 cases of gonorrhoea occurred. The overall IR for chlamydia ranged from 18.81 to 25.63 cases per 10,000 person-years. The IRR was 1.27 (95% CI 1.20-1.34, p < 0.001) for the comparison of 2015 and 2010 rates. For gonorrhoea, overall rates ranged from 0.92 to 1.86 cases per 10,000 person-years. The IRR for gonorrhoea was 2.02 (95% CI 1.56-2.59, p < 0.001) for 2015 and 2010 rates. In our large population-based study spanning six years, we observed increasing rates of C. trachomatis and N. gonorrhoeae with low testing rates.

Abstract
PURPOSE Little is known about the features of gastric cancer located in the lesser and greater curve. This study aims to investigate the clinicopathological features and prognosis of gastric cancer located in the lesser and greater curve. PATIENTS From September 2008 to March 2015, 780 gastric cancer patients were enrolled in the present study. The associations between locations and features of patients were analyzed. RESULTS There were 571 male (73.2 %) and 209 female (26.8 %) patients. The median age was 56 years (ranged 21-86). There were 684 tumors located in the lesser curve (87.7 %) and 96 located in the greater curve (12.3 %). The incidence of melena was significantly lower in patients with tumors located in the lesser curve than that in the greater curve (8.5 vs 15.6 %, P = 0.024). The median size of tumors in the lesser curve was significantly larger than that in the greater curve (5.0 (0.3-15) vs 4.0 cm (0.5-15), P = 0.001). The remaining clinicopathological features were comparable between the two groups (all P > 0.05). Tumor location was not a risk factor for the prognosis of gastric cancer by univariate and multivariate analysis (both P > 0.05). The postoperative complications (all P > 0.05) and prognoses (P = 0.279) were comparable between tumors located in the lesser and greater curve. CONCLUSIONS The ratio of gastric cancer located in the lesser to greater curve was 7.1:1. Compared with tumors located in the greater curve, the incidence of melena was significantly lower and the tumor size was significantly larger in tumors located in the lesser curve. The prognoses were comparable between tumors located in the lesser and greater curve.

Abstract
OBJECTIVE To explore the relationship between early adulthood weight status and body weight changes from early adulthood to middle age and high-density lipoprotein cholesterol (HDL-C) level. METHODS Data were obtained from China Multicenter Collaborative Study of Cardiovascular Epidemiology Study, which was conducted in 1998, 15 participants population samples aged from 35-59 years old from 12 provinces were selected by random cluster sampling. Approximately 1 000 men and women in each sample population were surveyed for cardiovascular disease risk factors, body weight at age 25 from all participants were also obtained. Body mass index (BMI) at the age of 25 years was calculated with the weight at 25 years and the height measured during the survey, participants were divided into underweight (BMI<18.5 kg/m(2), n=1 331), normal-weight (18.5 kg/m(2)≤BMI <24 kg/m(2), n=10 400), overweight (24 kg/m(2)≤BMI<28 kg/m(2), n=2 019) and obesity (BMI≥28 kg/m(2), n=133) groups. Weight change was defined as the difference between the body weight at the age of 25 and at the survey and was grouped into<-7.5 kg (n=903), -7.5--2.6 kg (n=1 883), -2.5-2.5 kg (n=2 573), 2.6-7.5 kg (n=2 786), 7.6-12.5 kg (n=2 674) and>12.5 kg (n=3 064). The association of body weight status in early adulthood and body weight change from early adulthood to middle age with HDL-C level was examined by logistic regression model. RESULTS The prevalence of low HDL-C in underweight, normal weight, overweight and obesity groups at age of 25 years were 10.7%(143/1 331), 15.5%(1 612/10 400), 16.3%(330/2 019) and 24.8%(33/133), respectively(P for trend <0.01). The prevalence of low HDL-C for adult weight change were 8.8%(79/903), 8.0%(151/1 883), 10.5%(269/2 573), 13.4%(373/2 786), 19.1%(511/2 674), and 24.0%(735/3 064)(P for trend <0.01)for weight change of <-7.5 kg, -7.5--2.6 kg, -2.5-2.5 kg, 2.6-7.5 kg, 7.6-12.5 kg and>12.5 kg, respectively. Multivariate logistic regression showed that overweight and obesity at age of 25 years and subsequent weight gain till middle age were positively correlated with low HDL-C after adjusted other risk factors(all P for trend <0.01). CONCLUSION Overweight and obesity in early adulthood and significant adult weight gain from early adulthood to middle age were both independently associated with marked increases in the risk of low HDL-C in middle-aged Chinese men and women. Thus, body weight control at early adulthood could be a key strategy to reduce the incidence of low HDL-C at middle-aged population.

Abstract
BACKGROUND Omalizumab (Xolair) dosing in severe allergic asthma is based on serum IgE and bodyweight. In Australia, patients eligible for omalizumab but exceeding recommended ranges for IgE (30-1500 IU/mL) and bodyweight (30-150 kg) may still receive a ceiling dose of 750 mg/4 weeks. About 62% of patients receiving government-subsidized omalizumab are enrolled in the Australian Xolair Registry (AXR). OBJECTIVES To determine whether AXR participants above the recommended dosing ranges benefit from omalizumab and to compare their response to within-range participants. METHODS Data were stratified according to dose range status (above-range or within-range). Further sub-analyses were conducted according to the reason for being above the dosing range (IgE only vs. IgE and weight). RESULTS Data for 179 participants were analysed. About 55 (31%) were above recommended dosing criteria; other characteristics were similar to within-range participants. Above-range participants had higher baseline IgE [812 (IQR 632, 1747) IU/mL vs. 209 (IQR 134, 306) IU/mL] and received higher doses of omalizumab [750 (IQR 650, 750) mg] compared to within-range participants [450 (IQR, 300, 600) mg]. At 6 months, improvements in Juniper 5-item Asthma Control Questionnaire (ACQ-5, 3.61 down to 2.01 for above-range, 3.47 down to 1.93 for within-range, P < 0.0001 for both) and Asthma Quality of Life Questionnaire (AQLQ mean score (3.22 up to 4.41 for above-range, 3.71 up to 4.88 for within-range, P < 0.0001) were observed in both groups. Forced expiratory volume in one second (FEV1 ) improved among above-range participants. There was no difference in response between above-range and within-range participants. Above-range participants due to either IgE alone or IgE and weight had similar improvements in ACQ-5, AQLQ and FEV1 . CONCLUSIONS AND CLINICAL RELEVANCE Patients with severe allergic asthma above recommended dosing criteria for omalizumab have significantly improved symptom control, quality of life and lung function to a similar degree to within-range participants, achieved without dose escalation above 750 mg.

Abstract
WHAT IS KNOWN AND OBJECTIVES Choosing an alternative statin is recommended when managing statin-associated muscle symptoms (SAMS) and new hydrophilic statins are often suggested. We report on a case of statin-associated muscle damage that was successfully managed by simplifying the patient's combination therapy with simvastatin-ezetimibe to simvastatin alone. CASE SUMMARY The patient experienced SAMS when he was successively treated with atorvastatin, rosuvastatin, Xuezhikang capsule and combined simvastatin/ezetimibe therapy. However, the patient tolerated simvastatin therapy well even at a dose of 40 mg/day. WHAT IS NEW AND CONCLUSION Our case suggests that patients with SAMS who are intolerant to a wide variety of statins may be successfully managed with simvastatin monotherapy.

Abstract
Ochratoxin A (OTA) induced DNA damage, cytotoxicity, and apoptosis in mammalian cell lines. Micro RNAs (miRNAs) are involved in physiological and developmental processes and contribute to cancer development and progression. In our study, high-throughput miRNA profiling and Kyoto Encyclopedia of Genes and Genomes analysis were applied to comparatively study the toxicity of OTA in HEK293 cells and HepG2 cells treated with 25 μM OTA for 24 h. In these two cells, the same changing miRNAs were mostly related to signal transduction pathways, whereas the different changing miRNAs were mostly related to human cancer pathways. DGCR8, Dicer1, and Drosha were significantly suppressed in HEK293 cells, indicating an impairment of miRNA biogenesis. The damage seemed more extensive in HEK293 cells. Cell models and in vivo models were also compared. Many miRNAs in vitro were markedly different from those in vivo; however, OTA toxicity was observed both in vitro and in vivo. The classification of deregulated pathways is similar. The biogenesis of miRNA was impaired in both lines. In conclusion, deregulated miRNAs in vitro are mostly related to human cancer and signal transduction pathways. The deregulated pathways in vivo are similar to those in vitro.

Abstract
Eribulin is indicated in the EU for advanced/metastatic breast cancer patients following ≥1 prior chemotherapy for advanced disease, and anthracycline and taxane in adjuvant/metastatic setting. We pooled 1644 patients from two phase III trials and found that eribulin significantly increased survival versus control, particularly in some subgroups of interest like HER2- and triple-negative disease. Background Based on data from two multicenter, phase III clinical trials (Studies 301 and 305), eribulin (a microtubule dynamics inhibitor) is indicated in the European Union (EU) for patients with locally advanced or metastatic breast cancer (MBC) after ≥1 prior chemotherapy for advanced disease, including an anthracycline and a taxane in either the adjuvant or metastatic setting. Data from Studies 305 and 301 were pooled to investigate the efficacy of eribulin in various subgroups of patients who matched the EU label, including those with human epidermal growth factor receptor 2 (HER2)-negative and triple-negative disease. Patients and methods In Study 305 (NCT00388726), patients were randomized 2:1 to eribulin mesylate 1.4 mg/m2 (equivalent to eribulin 1.23 mg/m2 [expressed as free base]) intravenously on days 1 and 8 every 21 days] or treatment of physician's choice after 2–5 prior chemotherapies (≥2 for advanced disease), including an anthracycline and a taxane (in early/advanced setting). In Study 301 (NCT00337103), patients were randomized 1:1 to eribulin (as above) or capecitabine (1.25 g/m2 orally twice daily on days 1–14 every 21 days) following ≤3 prior chemotherapies (≤2 for advanced disease), including an anthracycline and a taxane. Efficacy end points were investigated in the intent-to-treat population and subgroups, pooled as discussed above. Results Overall, 1644 patients were included (eribulin: 946; control: 698); baseline characteristics were well matched. Overall survival was significantly longer with eribulin versus control (P < 0.01), as were progression-free survival and clinical benefit rate (both P < 0.05). Significant survival benefits with eribulin versus control were observed in a wide range of patient subgroups, including HER2-negative or triple-negative disease (all P < 0.05). Conclusion Our findings underline the survival benefit achieved by eribulin used according to EU label in the overall MBC population and in various subgroups of interest, including patients with HER2-negative and triple-negative disease.

[PMID: 26092802 PMCID: PMC4502456 DOI: 10.1016/j.fgb.2015.04.014] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2015] [Revised: 04/10/2015] [Accepted: 04/13/2015] [Indexed: 11/25/2022]
Abstract
We establish Z. tritici polarity markers ZtSec4, ZtMlc1, ZtRab11, ZtExo70 and ZtSpa2. All markers localize correctly, labeling the Spitzenkörper and sites of polar exocytosis. We provide 5 carboxin-resistance conveying vectors for integration of all markers into the sdi1 locus. We provide 5 hygromycin B-resistance conveying vectors for random integration of all markers.
Fungal hyphae are highly polarized cells that invade their substrate by tip growth. In plant pathogenic fungi, hyphal growth is essential for host invasion. This makes polarity factors and secretion regulators potential new targets for novel fungicides. Polarization requires delivery of secretory vesicles to the apical Spitzenkörper, followed by polarized exocytosis at the expanding cell tip. Here, we introduce fluorescent markers to visualize the apical Spitzenkörper and the apical site of exocytosis in hyphae of the wheat pathogen Zymoseptoria tritici. We fused green fluorescent protein to the small GTPase ZtSec4, the myosin light chain ZtMlc1 and the small GTPase ZtRab11 and co-localize the fusion proteins with the dye FM4-64 in the hyphal apex, suggesting that the markers label the hyphal Spitzenkörper in Z. tritici. In addition, we localize GFP-fusions to the exocyst protein ZtExo70, the polarisome protein ZtSpa2. Consistent with results in the ascomycete Neurospora crassa, these markers did localize near the plasma membrane at the hyphal tip and only partially co-localize with FM4-64. Thus, these fluorescent markers are useful molecular tools that allow phenotypic analysis of mutants in Z. tritici. These tools will help develop new avenues of research in our quest to control STB infection in wheat.

Abstract
We establish Z. tritici fimbrin (ZtFim1) and small GTPases (ZtRab5, ZtRab7) as endocytic markers. All markers localize correctly, proven by live cell imaging and co-staining and pharmaceutical studies. We provide 3 carboxin-resistance conveying vectors for integration of all markers into the sdi1 locus. We provide 3 hygromycin B-resistance conveying vectors for random integration of all markers.
Hyphal growth in filamentous fungi is supported by the uptake (endocytosis) and recycling of membranes and associated proteins at the growing tip. An increasing body of published evidence in various fungi demonstrates that this process is of essential importance for fungal growth and pathogenicity. Here, we introduce fluorescent markers to visualize the endocytic pathway in the wheat pathogen Zymoseptoria tritici. We fused enhanced green-fluorescent protein (eGFP) to the actin-binding protein fimbrin (ZtFim1), which is located in actin patches that are formed at the plasma membrane and are participating in endocytic uptake at the cell surface. In addition, we tagged early endosomes by eGFP-labelling a Rab5-homologue (ZtRab5) and late endosomes and vacuoles by expressing eGFP-Rab7 homologue (ZtRab7). Using fluorescent dyes and live cell imaging we confirmed the dynamic behavior and localization of these markers. This set of molecular tools enables an in-depth phenotypic analysis of Z. tritici mutant strains thereby supporting new strategies towards the goal of controlling wheat against Z. tritici.
