In this work, the high κ Zr x Al 1−x O y fi lms with a diff erent Zr concentration have been deposited by atomic layer deposition,and the eff ect of Zr concentrations on the structure, chemical composition, surface morphology and dielectric propertiesof Zr x Al 1−x O y fi lms is analyzed by Atomic force microscopy, X-ray diff raction, X-ray photoelectron spectroscopy andcapacitance-frequency measurement. The eff ect of Zr concentrations of Zr x Al 1-x O y gate insulator on the electrical propertyand stability under negative bias illumination stress (NBIS) or temperature stress (TS) of ZnSnO (ZTO) TFTs is fi rstlyinvestigated. Under NBIS and TS, the much better stability of ZTO TFTs with Zr x Al 1−x O y fi lm as a gate insulator is due tothe suppression of oxygen vacancy in ZTO channel layer and the decreased trap states originating from the Zr atom permeationat the ZTO/Zr x Al 1−x O y interface. It provides a new strategy to fabricate the low consumption and high stability ZTOTFTs for application.

Background: To examine the expression of cysteine-rich 61 (Cyr61/CCN1) protein in laryngeal squamouscell carcinoma (LSCC) tissues, and its relationship with the tumor epithelial-mesenchymal transition (EMT), invasion, metastasis, and prognosis. Materials and Methods: Immunohistochemistry was used to detect the expressions of Cyr61, Vimentin (Vim), and E-cadherin (E-cad) in 88 cases of LSCC tissues and 30 cases of tumor-adjacent normal tissues. Vim and E-cad were used as mesenchymal and epithelial markers, respectively, to determine the relationship between Cyr61 expression and the EMT of LSCC cells. In addition, clinical and histopathological data were combined to analyze the relationship between the positive-expression rates of Cyr61, Vim and E-cad and LSCC invasion, metastasis and prognosis. Results: In LSCC tissues, Vim expression rate was significantly higher than that of the tumor-adjacent tissues, whereas E-cad expression rate was significantly lower than that of the tumor-adjacent tissues. The Vim expression rate was significantly higher in stages T3 and T4 than in stages T1 and T2 LSCC tissues, whereas E-cad expression rate was significantly lower in stages T3 and T4 than in stages T1 and T2 LSCC tissues. Compared to the group without lymph node metastasis, the Vim expression rate was significantly higher and the E-cad expression rate was significantly lower in the group with lymph node metastasis. The expression rate of Cyr61 was significantly higher in LSCC tissues than in the tumor-adjacent normal tissues. In addition, the Cyr61 expression rate was higher in stages T3 and T4 than in stages T1 and T2 LSCC, and higher in the group with lymph node metastasis than in the group without lymph node metastasis. The Vim expression rate was significantly higher in the Cyr61 positive group than in the Cyr61 negative group, whereas the E-cad expression rate was significantly higher in the Cyr61 negative group than in the Cyr61 positive group. Survival analysis indicated that survival rates of Cyr61 positive, Vim positive and E-cad negative groups were significantly lower than that of Cyr61 negative, Vim negative and E-cad positive groups, respectively. Conclusions: Cyr61 expression is closely associated with LSCC invasion and lymph node metastasis. Overexpression of Cyr61 may induce EMT and therefore leads to LSCC invasion and metastasis and poor prognosis. Cyr61 may become a new maker for clinical prediction of LSCC invasion and metastasis and a new target for LSCC treatment.

The volatile compounds in Chinese soy sauce moromi cultured by different fermentation processes [lowsalt solid-state fermentation (LSSF), high-salt dilute-state fermentation (HSDF), and high-salt constant temperature fermentation (HSCT)] were determined by GC-MS. The LSSF moromi had the highest total concentration of volatile compounds, followed by HSCT and HSDF moromi. Volatiles such as ethyl linoleate and ethyl oleate dominated in HSCT moromi. 2,3-Butanediol and 2,6-dimethylpyrazine were present at high content in LSSF moromi. The hierarchal cluster analysis (HCA) and principal component analysis (PCA) were employed to investigate the fermentation process effect on the category of samples. Based on HCA,HSCT (a1 and a2) and HSDF (b1 and b2) clustered in 1group, and LSSF (c1 and c2) located in another group. PCA illustrated that each kind of samples correlating with specific volatile compound groups were clearly differentiated according to their fermentation processes. The results suggest that GC-MS together with multivariate analyses could provide practical reference to recognize different Chinese soy sauces moromi.

CO2 fluxes were measured continuously for three years (2003-2005) using the eddy covariance technique for the canopy layer with a height of 27 m above the ground in a dominant subtropical evergreen forest in Dinghushan, South China. By applying gapfilling methods, we quantified the different components of the carbon fluxes (net ecosystem exchange (NEE)), gross primary production (GPP) and ecosystem respiration (Reco) in order to assess the effects of meteorological variables on these fluxes and the atmospherecanopy interactions on the forest carbon cycle. Our results showed that monthly average daily maximum net CO2 exchange of the whole ecosystem varied from −3.79 to −14.24 μmol m−2 s−1 and was linearly related to photosynthetic active radiation. The Dinghushan forest acted as a net carbon sink of −488 g C m−2 y−1, with a GPP of 1448 g Cm−2 y−1, and a Reco of 961 g C m−2 y−1.Using a carboxylase-based model, we compared the predicted fluxes of CO2 with measurements. GPP was modelled as 1443 g C m−2 y−1, and the model inversion results helped to explain ca. 90% of temporal variability of the measured ecosystem fluxes. Contribution of CO2 fluxes in the subtropical forest in the dry season (October-March) was 62.2% of the annual total from the whole forest ecosystem. On average, 43.3%of the net annual carbon sink occurred between October and December, indicating that this time period is an important stage for uptake of CO2 by the forest ecosystem from the atmosphere. Carbon uptake in the evergreen forest ecosystem is an indicator of the interaction of between the atmosphere and the canopy, especially in terms of driving climate factors such as temperature and rainfall events. We found that the Dinghushan evergreen forest is acting as a carbon sink almost year-round. The study can improve the evaluation of the net carbon uptake of tropical monsoon evergreen forest ecosystem in south China region under climate change conditions.

Background: The common reference intervals (RIs) for thyroid hormones currently used in China are provided by equipment manufacturers. This study aimed to establish thyroid hormone RIs in the population of Lanzhou, a city in the subplateau region of northwest China, and compare them with previous reports and manufacturer-provided values. Methods: In total, 3,123 individuals (1,680 men, 1,443 women) from Lanzhou, an iodine-adequate area of China, perceived ashealthy were selected. The Abbott Architect analyzer was used to determine the serum concentration of thyroid hormones. The 95%RI was estimated using the 2.5th and 97.5th percentiles as the lower and upper reference limits, respectively. Results: The serum levels of thyroid-stimulating hormone (TSH), total triiodothyronine (TT3), antithyroglobulin (ATG) antibody,and antithyroid peroxidase (ATPO) antibody levels were significantly correlated with sex (P<0.05). TSH, total thyroxine (TT4), andATPO levels were significantly correlated with age (P<0.05). The serum levels of TSH, ATG, and ATPO in men were significantlylower than in women; in contrast, the serum TT3 level was significantly higher in men than in women (P<0.05). Serum TSH, TT3,TT4, and ATG levels differed across age groups (P<0.05), but no such variation was observed for ATG levels (P>0.05). The established RIs of TSH, ATG, and ATPO in this study differed between sexes (P<0.05). The thyroid hormone RIs established herein wereinconsistent with the manufacturer-provided values. Conclusion: The RIs of thyroid hormones in the healthy population of Lanzhou were inconsistent with those in the manufacturer’smanual. Validated sex-specific values are required for diagnosing thyroid diseases.

Background/Aims: Methylation status plays a causal role in carcinogenesis in targeted tissues. However, the relationship between the DNA methylation status of multiple genes in blood leukocytes and colorectal cancer (CRC) susceptibility as well as interactions between dietary factors and CRC risks are unclear. Methods: We performed a case-control study with 466 CRC patients and 507 cancer-free controls to investigate the association among the methylation status of individual genes, multiple CpG site methylation (MCSM), multiple CpG site heterogeneous methylation and CRC susceptibility. Peripheral blood DNA methylation levels were detected by performing methylation-sensitive high-resolution melting. Results: Total heterogeneous methylation of CA10 and WT1 conferred a significantly higher risk of CRC (adjusted odds ratio [ORadjusted], 5.445; 95% confidence interval [CI], 3.075 to 9.643; ORadjusted, 1.831; 95% CI, 1.100 to 3.047; respectively). Subjects with high-level MCSM (MCSM-H) status demonstrated a higher risk of CRC (ORadjusted, 4.318; 95% CI, 1.529 to 12.197). Additionally, interactions between the high-level intake of fruit and CRH, WT1, and MCSM on CRC were statistically significant. Conclusions: The gene methylation status of blood leukocytes may be associated with CRC risk. MCSM-H of blood leukocytes was associated with CRC, especially in younger people. Some dietary factors may affect hypermethylation status and influence susceptibility to CRC.
