< Mr. Tree(hello!樹先生) >: The Core of Realism Carried in the form of Surrealism
( Song Jian ) 국제문화&예술학회 2021 국제문화예술 Vol.2 No.1
The film “Mr. Tree” is a Chinese film with both the spiritual core of realism and the style of surrealism. The film’s narrative methods and visual representations are mixed, and it combines many realistic and surreal elements and symbols. The film is not only inked In the plight of rural youth, it also expresses the filmmakers’ torture of reality with excellent metaphorical mirror images.

BaCeO3-based ceramics are a unique class of perovskites that exhibit protonic and oxygen ionic conduction,which are ideal for high temperature hydrogen separation applications. This work features Sc-dopedBCFe composites with nominal composition of BaCe0.70Fe0.30-xScxO3d (BCFSc) (x = 0, 0.05, 0.1, 0.15, and0.2) that exhibit enhanced thermal, chemical, and mechanical stability. The BCFSc20 (x = 0.20) hollowfiber membranes demonstrated the highest hydrogen and oxygen fluxes among the Sc-doped compositesof up to 0.32 and 0.20 mL min1 cm2, respectively, at 1000 C. The BCFSc20 hollow fibers also displayedexcellent stability under the hydrogen and oxygen permeation environments, while the permeation performanceof the other BCFSc samples with low Sc content gradually deteriorated over the 120-h stabilitytest.

Polymorphisms in miRNA binding sites have been shown to affect miRNA binding to target genes, resulting in differential mRNA and protein expression and susceptibility to common diseases. Our purpose was to predict SNPs (single nucleotide polymorphisms) within miRNA binding sites of inflammatory genes in relation to gastric cancer. A complete list of SNPs in the 3'UTR regions of all inflammatory genes associated with gastric cancer was obtained from Pubmed. miRNA target prediction databases (MirSNP, Targetscan Human 6.2, PolymiRTS 3.0, miRNASNP 2.0, and Patrocles) were used to predict miRNA target sites. There were 99 SNPs with MAF>0.05 within the miRNA binding sites of 41 genes among 72 inflammation-related genes associated with gastric cancer. NF-${\kappa}B$ and JAK-STAT are the two most important signaling pathways. 47 SNPs of 25 genes with 95 miRNAs were predicted. CCL2 and IL1F5 were found to be the shared target genes of hsa-miRNA-624-3p. Bioinformatic methods could identify a set of SNPs within miRNA binding sites of inflammatory genes, and provide data and direction for subsequent functional verification research.

Background: The study aimed to describe the age distribution of breast cancer diagnosis among Chinese females for comparison with the United States and the European Union, and provide evidence for the screening target population in China. Materials and Methods: Median age was estimated from hospital databases from 7 tertiary hospitals in China. Population-based data in China, United States and European Union was extracted from the National Central Cancer Registry, SEER program and GLOBOCAN 2008, respectively. Age-standardized distribution of breast cancer at diagnosis in the 3 areas was estimated based on the World Standard Population 2000. Results: The median age of breast cancer at diagnosis was around 50 in China, nearly 10 years earlier than United States and European Union. The diagnosis age in China did not vary between subgroups of calendar year, region and pathological characteristics. With adjustment for population structure, median age of breast cancer at diagnosis was 50~54 in China, but 55~59 in United States and European Union. Conclusions: The median diagnosis age of female breast cancer is much earlier in China than in the United States and the European Union pointing to racial differences in genetics and lifestyle. Screening programs should start at an earlier age for Chinese women and age disparities between Chinese and Western women warrant further studies.

Due to the characteristics of deep burial, abnormal pressure, high bottom hole temperature, and abundant fractures, the tightoil reservoirs in the Leijia block of Liaohe Oilfield have many complex situations such as lost circulation and electricalresistance encountered, which seriously restricts the development of tight oil and gas resources in Leijia. Safe and efficientdevelopment. To solve this problem, firstly, the mechanism of the wellbore instability of the tight mud shale in the Leijia blockwas studied. Then, the formula of the composite salt base fluid was optimized by using the principle of activity balance, andthe nano-plugging with core-shell structure was developed in a targeted manner. Finally, a high-performance drilling fluidsystem with strong plugging, strong inhibition and strong lubrication was constructed. The temperature resistance of thesystem reaches 150 °C, the primary recovery rate of shale is 97.8%, the permeability is reduced by more than 50%, and HTHP(150 °C) is less than or equal to 8 mL. In the test of Well L77-HX in Leijia block, the accident complexity rate is 0, the successrate of electrical measurement is 100%, the ROP is increased by 40%, the drilling depth is 5000m, and the horizontaldisplacement is 1783m. This new compound salt high-performance drilling fluid system provides technical support.

Background: Matrix metalloproteinase 9 (MMP-9) is related to tumor invasion and metastasis. However, the role of MMP-9 expression in breast cancer survival remains controversial. The purpose of this study was to accomplish a more accurate estimation of the association between MMP-9 expression and survival results in breast cancer patients through meta-analysis. Methods: A meta-analysis of published studies investigating the effects of positive MMP-9 expression on both relapse free survival (RFS) and overall survival (OS) was performed. Relevant literature was confirmed by searching electronic databases including PubMed, Ovid, EMBASE and China National Knowledge Infrastructure (CNKI) before November 1, 2012. Individual hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted and pooled HRs with 95% CIs were used to evaluate the strength of the association between positive MMP-9 expression and survival results of breast cancer patients. Funnel plot and Egger's regression tests were used to evaluate publication bias. Heterogeneity and sensitivity analysis was also conducted. All the work was completed using STATA. Results: A total of 2,344 patients from 15 evaluative studies were finally included. Pooled HRs and 95% CIs suggested that MMP-9 overexpression had an unfavorable impact on both OS (HR: 1.70, 95% CI: 1.41-2.04) and RFS (HR: 1.54, 95% CI: 1.17-2.01) in breast cancer patients. There was no significant heterogeneity observed in the studies reported for OS (P=0.360, $I^2$=8.8%), but not RFS (P=0.002, $I^2$=67%). Publication bias was absent among the studies both in OS and RFS cases (t=-0.54, P=0.605 and t=1.71, P=0.131, respectively). Omission of any single study had little effect on the combined risk estimates on sensitivity analysis. Conclusion: The results of this meta-analysis suggest that positive MMP-9 expression confers a higher risk of relapse and a worse survival in patients with breast cancer. Larger prospective studies are now needed to evaluate the clinical utility of MMP-9 expression.

Leptospirillum ferriphilum and Acidithiobacillus caldus are two important acidophilic microorganisms involved in iron and sulfur oxidation during bioleaching. Cell adsorption to mineral surfaces is important for the direct leaching or contact leaching of minerals. In this study, we report the competitive adsorption of binary mixtures of L. ferriphilum LF-104 and A. caldus MTH-04onto pyrite surfaces. The Langmuir adsorption parameter (CAm) indicated that these two bacteria underwent competitive adsorption to pyrite. Real-time quantitive PCR was used to quantify the relative amounts of L. ferriphilum and A. caldus adsorbed onto the surfaces of pyrite following exposure to a mixture of these two organisms. The adsorption of L. ferriphilum was not affected by A. caldus. However, adsorption of A. caldus was greatly affected by the presence of L. ferriphilum. Zeta-potential measurements and FT-IR spectroscopic studies showed that L. ferriphilum had a higher electrostatic attraction towards pyrite when compared to A. caldus. Based on the above results, we propose a competitive adsorption model to explain the mechanism by which L. ferriphilum and A. caldus compete in their adsorption to pyrite, although L. ferriphilum dominated in the competitive adsorption process. This work provides a better understanding of the adsorption behavior of mixed microbial populations onto mineral surfaces.
