    AIM: The risk factors for hepatocellular carcinoma (HCC) development in chronic hepatitis B (CHB) patients with undetectable serum HBV DNA under nucleos(t)ide analogue (NA) therapy are not well defined. We aimed to examine the relationship between Wisteria floribunda agglutinin-positive human Mac-2 binding protein (WFA+-M2BP) and HCC development in these patients. RESULTS: There was a significant difference in the median levels of pre-treatment WFA+-M2BP between the HCC and control groups (0.67 vs 0.41 COI, respectively, p < 0.001). Among patients with cirrhosis, the median level of WFA+-M2BP was higher in HCC group than in control group (0.74 vs 0.47 COI, respectively, p = 0.014). Among patients without cirrhosis, the median level of WFA+-M2BP of HCC group was also higher (0.48 vs 0.28 COI, respectively, p = 0.002). With a cutoff value of 0.69, the AUROC of pre-treatment WFA+-M2BP to predict HCC development for the whole cohort was 0.70. With cutoff values of 0.69 and 0.34, the AUROCs to predict HCC were 0.67 and 0.77 for patients with and without cirrhosis, respectively. MATERIALS AND METHODS: Fifty-seven NA-treated patients with undetectable HBV DNA who developed HCC were compared with 57 controls (matched with demographics and treatment duration). WFA+-M2BP levels were measured, and expressed as cutoff index (COI). Subgroup analyses were also performed in patients with and without cirrhosis. CONCLUSIONS: A higher pre-treatment WFA+-M2BP level was associated with an increased risk of HCC development in patients with undetectable HBV DNA under NA therapy. Further longitudinal studies are required to examine the role of WFA+-M2BP as an accessory risk marker for HCC development.published_or_final_versio

    Paracoccus denitrificans DL-23, isolated from aerobic domesticated activated sludge, was demonstrated to have high ability of denitrification and heterotrophic nitrification under aerobic condition. After optimization (succinate, COD/N 10, 37°C, 160 rpm), DL-23 removed 420 and 860 mg/l NO3--N within 36 to 60 h of growth, respectively. DL-23 also removed 380 mg/l NH4+-N within 24 h with ammonia as nitrogen source. The maximum removal rate was 30.3 mg/l·h. Meanwhile, DL-23 exhibited aerobic nitrite reduction ability with 658 mg/l NO2--N within 48 h.Key words: Aerobic denitrification, heterotrophic nitrification, nitrogen removal, Paracoccus denitrificans

    Continuous entecavir for treatment-naïve Chinese chronic hepatitis B in the real world setting: the six-year results

    This journal suppl. entitled: 2014 DDW AbstractBACKGROUND: There is a paucity of data on uninterrupted entecavir for treatment-naive chronic hepatitis B (CHB) beyond 5 years. METHODS: Treatment-naive Chinese CHB patients were treated continuously with entecavir 0.5mg daily in the real world setting for up to 6 years. The cumulative rates of hepatitis B e antigen (HBeAg) seroconversion, alanine aminotransferase (ALT) normalization, DNA undetectability, virologic breakthrough (>1 log HBV DNA increase from the nadir) and genotypic resistance to entecavir were determined. HBV DNA levels were measured by Roche Taqman real time PCR assay (lower limit of detection: 20 IU/mL). Resistance profile was determined by line probe assay (LiPA, Innogenetics NV, Gent, Belgium) for patients ...postprin

    Scalp acupuncture for acute ischemic stroke: a meta-analysis of randomized controlled trials

    Get PDF
    Scalp acupuncture (SA) is a commonly used therapeutic approach for stroke throughout China and elsewhere in the world. The objective of this study was to assess clinical efficacy and safety of SA for acute ischemic stroke. A systematical literature search of 6 databases was conducted to identify randomized controlled trials (RCTs) of SA for acute ischemic stroke compared with western conventional medicines (WCMs). All statistical analyses were performed by the Rev Man Version 5.0. Eight studies with 538 participants were included in the studies. The studies were deemed to have an unclear risk of bias based on the Cochrane Back Review Group. Compared with the WCM, 6 RCTs showed significant effects of SA for improving neurological deficit scores (P < 0.01); 4 RCTs showed significant effects of SA for favoring the clinical effective rate (P < 0.01) However, the adverse events have not been documented. In conclusion, SA appears to be able to improve neurological deficit score and the clinical effective rate when compared with WCM, though the beneficial effect from SA is possibly overvalued because of generally low methodology of the included trials. No evidence is available for adverse effects. Rigorous well-designed clinical trials are needed.published_or_final_versio

    Combined Anterior-Posterior Surgery Versus Posterior Surgery for Thoracolumbar Burst Fractures: A Systematic Review of the Literature

    Get PDF
    Abstract: Study Design: A systematic quantitative review of the literature. Objective: To compare combined anterior-posterior surgery versus posterior surgery for thoracolumbar fractures in order to identify better treatments. Summary of Background Data: Axial load of the anterior and middle column of the spine can lead to a burst fracture in the vertebral body. The management of thoracolumbar burst fractures remains controversial. The goals of operative treatment are fracture reduction, fixation and decompressing the neural canal. For this, different operative methods are developed, for instance, the posterior and the combined anterior-posterior approach. Recent systematic qualitative reviews comparing these methods are lacking. Methods: We conducted an electronic search of MEDLINE, EMBASE, LILACS and the Cochrane Central Register for Controlled Trials. Results: Five observational comparative studies and no randomized clinical trials comparing the combined anteriorposterior approach with the posterior approach were retrieved. The total enrollment of patients in these studies was 755 patients. The results were expressed as relative risk (RR) for dichotomous outcomes and weighted mean difference (WMD) for continuous outcomes with 95% confidence intervals (CI). Conclusions: A small significantly higher kyphotic correction and improvement of vertebral height (sagittal index) observed for the combined anterior-posterior group is cancelled out by more blood loss, longer operation time, longer hospital stay, higher costs and a possible higher intra- and postoperative complication rate requiring re-operation and the possibility of a worsened Hannover spine score. The surgeons’ choices regarding the operative approach are biased: worse cases tended to undergo the combined anterior-posterior approach
