AIM： To investigate the correlation between the serum soluble intercellular adhesion molecule-1 （sICAM-1） and the clinicopathologic features and to evaluate the possible prognostic significance of sICAM-1 concentration in colorectal ***： A total of 56 patients （mean age 57.3 years） having transitional cell carcinoma of the colorectal and 25 control patients （mean age 42.6 years） were enrolled in the study. The serum samples of the patients were obtained on the day before surgery. Sera were obtained by centrifugation, and stored at -80℃ until assay. Serum concentrations of ICAM-1 were measured with enzymelinked immunoassay. Differences between the two groups were analyzed by Student＇s ***： No significant increase of serum slCAM-1 could be demonstrated in the Dukes A1 patients （352.63±61.82μg/L） compared to the control group （345.72±49.81 μg/L,/〉〉0.05）, Dukes A1 patients （352.63±61.82 μg/L）compared to Dukes A2,3 patients （491.17±86.36μg/L,P〈0.05）. Furthermore, the patients with Dukes B had significantly higher serum concentrations of sICAM-1 than those of the control group （496.82±93.04μg/L vs 345.72±49.81μg/L, P〈0.01）. Compared with Dukes A2,3,B colorectal cancer patients, patients with more advanced clinical stage （Dukes C and D） had higher levels of sICAM-1 （743.68±113.74 μg/L vs491.17±86.36μg/L and 496.82±93.04 μg/L, P〈0.001）. The difference was statistically significant in sICAM-1 levels between patients with positive lymph node status and those without lymph node involvement （756.25±125.57μg/L vs 445.62±69.18 μg/L, P〈0.001）.Patients with poorly differentiated colorectal cancer had a higher level of slCAIVl-1 than those with differentiated and highly differentiated cancer （736.49±121.97μg/L vs410.23±67.47 μg/L, P〈0.001）.CONCLUSION： In this study, serum ICAM-1 levels were found to be related to tumor presence, clinical stages,and grade.

Objective: MicroRNAs(miRNAs) may be viable targets for treating renal interstitial fibrosis(RIF). Fuzheng Huayu recipe(FZHY), a traditional Chinese compound herbal medicine, is often used in China to treat fibrosis. This study sought to assess the mechanisms through which FZHY influences miRNAs to treat ***: RIF was induced in rats by mercury chloride and treated with FZHY. Hydroxyproline content,Masson’s staining and type I collagen expression were used to evaluate renal collagen *** miRNA profiles were evaluated using a miRNA microarray. Those miRNAs that were differentially expressed following FZHY treatment were identified and subjected to bioinformatic analyses. The miR-21 target gene phosphatase and tensin homolog(PTEN) expression and AKT phosphorylation in kidney tissues were assessed via Western blotting. In addition, HK-2 human proximal tubule epithelial cells were treated using angiotensin II(Ang-II) to induce epithelial-to-mesenchymal transition(EMT), followed by FZHY exposure. miR-21 and PTEN expressions were evaluated via quantitative reverse transcriptionpolymerase chain reaction(qRT-PCR), while E-cadherin and a-smooth muscle actin(a-SMA) expressions were assessed by immunofluorescent staining and qRT-PCR. Western blotting was used to assess PTEN and AKT ***: FZHY significantly decreased kidney collagen deposition, hydroxyproline content and type I collagen level. The miRNA microarray identified 20 miRNAs that were differentially expressed in response to FZHY treatment. Subsequent bioinformatic analyses found that miR-21 was the key fibrosis-related miRNA regulated by FZHY. FZHY also decreased PTEN expression and AKT phosphorylation in fibrotic kidneys. Results from in vitro tests also suggested that FZHY promoted E-cadherin upregulation and inhibited a-SMA expression in Ang-II-treated HK-2 cells, effectively reversing Ang-II-mediated EMT. We also determined that FZHY reduced miR-21 expression, increased PTEN ex

Hundreds of mine flooding accidents have occurred in China since the 1950s. These flooding accidents result in submerged working faces, even entire coal mines, leading to tremendous economic losses. It is reported that among 601 state-owned mines in China, 285 mines are exposed to water-inrush risks. The water pressure is becoming larger and larger with the increase of mining depth, leading to an increase of water-inrush hazards. Only when the risk of mine flooding is predicted in a reasonable manner, can we take timely and effective measures to prevent mine flooding from taking place. In our investigation quantification（H） theory is used to study the risk prediction problem about mine flooding. By investigating the main factors which affect mine flooding, eight risk assessment items have been identified. The extent of risk is classified into 4 grades. Given the data from different periods in the Feicheng mining area, a prediction model for the risk of mine flooding is established. The test analysis indicates a model correlation coefficient of 0.97 and the incidence of discrimination is as high as 97.37%, which implies that the effect of the model is quite satisfactory. With the help of computers, this method can be widely applied.

CO2 and O2 were employed as reactive gases to fabricate carbon-doped titanium oxide films using DC reactive magnetron sputtering. Microstructure, composition and optical band gap of the films were investigated by X-ray diffraction, X-ray photoelectron spectroscopy, and UV-visible spectrophotometer, respectively. The results showed that carbon-doped titanium monoxide films （C-TiO） with a carbon concentration of 5.8 at.% were obtained in an AffCO2 mixed atmosphere. However, carbon-doped futile and anatase （C-TiO2） with a carbon concentration of about 1.4 at.% were obtained in an Ar/CO2/O2 mixed atmosphere. The optical band gaps of C-TiO and C-TiO2 were about 2.6 and 2.9 eV, respectively. Both of them were narrower than that of pure TiO2 films. Films with narrowed optical band gap energy are promising in promoting their photo-catalytic activity.
