Background: A systematic review and meta-analysis were performed to compare the post-recurrence survival with hepatic re-resection versus transarterial chemoembolization (TACE) for recurrent hepatocellular carcinoma (HCC) after initial resection. Materials and Methods: All relevant papers were searched via PubMed, EMBASE, and Cochrane Library databases. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. Subgroup analysis was performed according to country. Sensitivity analysis was performed in studies which clearly reported the recurrent regions, in moderate/high-quality studies, in studies published in full-text form, and in studies published after 2005. Results: In total, twelve papers were included in our study. Five and seven of them were of moderate- and poor-quality, respectively. The overall meta-analysis demonstrated a statistically significantly higher post-recurrence survival in the hepatic re-resection group than in those undergoing TACE (HR=0.64, 95%CI=0.52-0.79, P<0.0001). Heterogeneity was statistically significant and statistical significance remained in the subgroup analysis. Sensitivity analyses were also consistent with the overall analysis. Conclusions: Hepatic re-resection might provide a better post-recurrence survival than TACE for recurrent HCC after initial resection. However, considering the low quality of published studies and the potential bias of treatment selection, further randomized trials should be warranted to confirm these findings.

The foundation pit construction risk of subway stations is affected by various uncertain factors, which cannot be analyzed quantitatively by current methods. A synthetic evaluation index system for foundation pit construction risk of subway stations is established by analyzing the factors that influence subway station construction. Based on the hierarchy of these factors, a model of three-stage fuzzy synthetic evaluation is proposed, an analytic hierarchy process is used to determine the weight of each stage factor, the fuzzy sets method is used to determine the membership function, and risk ranking is carried out. The proposed method is applied to a subway station construction of the Qingdao Subway Line No. 3 Project. The simulation results show that the method is reasonable and that it should be practical and helpful for other similar projects.

Methane production by methanogens in wetland is recognized as a significant contributor to global warming. Spartina alterniflora (S. alterniflora), which is an invasion plant in China’s wetland, was reported to have enormous effects on methane production. But studies on shifts in the methanogen community in response to S. alterniflora invasion at temporal and spatial scales in the initial invasion years are rare. Sediments derived from the invasive species S. alterniflora and the native species Phragmites australis (P. australis) in pairwise sites and an invasion chronosequence patch (4 years) were analyzed to investigate the abundance and community structure of methanogens using quantitative real-time PCR (qPCR) and Denaturing gradient gel electrophoresis (DGGE) cloning of the methyl-coenzyme M reductase A (mcrA) gene. For the pairwise sites, the abundance of methanogens in S. alterniflora soils was lower than that of P. australis soils. For the chronosequence patch, the abundance and diversity of methanogens was highest in the soil subjected to two years invasion, in which we detected some rare groups including Methanocellales and Methanococcales. These results indicated a priming effect at the initial invasion stages of S. alterniflora for microorganisms in the soil, which was also supported by the diverse root exudates. The shifts of methanogen communities after S. alterniflora invasion were due to changes in pH, salinity and sulfate. The results indicate that root exudates from S. alterniflora have a priming effect on methanogens in the initial years after invasion, and the predominate methylotrophic groups (Methanosarcinales) may adapt to the availability of diverse substrates and reflects the potential for high methane production after invasion by S. alterniflora.

Conduction Mechanism in (La0.7Sr0.3MnO3)n(BiFeO3)n Multilayered Thin Films
Huiwen Zhu,Shunli Wang,Ping Jiang,Jingqin Shen,Weihua Tang 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.2
(La0.7Sr0.3MnO3)n(BiFeO3)n multilayered thin films were deposited on (0 0 1) SrTiO3 substrates by using the RF magnetron sputtering method, and their conduction mechanisms in the temperature range between 150 K and 300 K were investigated using several common dielectric conduction models. The results indicate the current-voltage characterization of the as-fabricated thin films obey Ohm’s law at 300 K, but the space-charge-limited conduction mechanism becomes dominant in the as-fabricated thin films as the temperature is decreased.

Objective: The relationship of antipsychotics and the risk of refracture in treated patients is unclear. The aim of this study is to evaluate the association between prolonged antipsychotic and the incidences of bone fractures and refractures in schizophrenia. Methods: This is a retrospective nested case-control study using Taiwan National Health Insurance Research Database recorded from 2000 to 2005, with cases followed up to end of 2011. Total of 7,842 schizophrenic patients, 3,955 had developed bone fractures were compared with 3,887 control subjects matched in age, sex, and index date. Antipsychotic drug exposure was classified based on the drug type and medication duration. Conditional logistic regression analyses were performed. Odds ratio (OR) and confidence interval (CI) were calculated. Results: We found (after adjustments) higher risks of developing fractures under continued use of typical (OR = 1.70; 95% CI, 1.51−1.91) or atypical antipsychotics (OR = 1.43; 95% CI, 1.28−1.60) were found. Additionally, continued use typical (OR = 1.84; 95% CI, 1.35−2.50) or atypical antipsychotics (OR = 1.44; 95% CI, 1.06−1.95) was positively associated with refracture risks. Moreover, refractures were associated with continuous use of chlorpromazine (one typical antipsychotics, OR = 2.45; 95% CI, 1.14−5.25), and risperidone (OR = 1.48; 95% CI, 1.01−2.16) or zotepine (OR = 2.15; 95% CI, 1.06−4.36) (two atypical antipsychotics). Conclusion: Higher risks of bone fracture and refracture were found in schizophrenia under prolonged medication with typical or atypical antipsychotics. We therefore recommend that clinicians should pay more attention on bone density monitoring for patients using long-term antipsychotics.
