Based on the importance of coastal saline-alkali soil remediation in Yellow River Delta, China, the Cl-、Na+ transferring tendency in soil and the saline-alkali soil eco-remediation effects were researched by measuring soil Cl-、Na+ 、soluble salt、soil respire rate and dry biomass weight of reed, etc. periodically. The results shows: the concentration of irrigated soil Cl-、Na+ and soluble salt were decreased 57.7-70%、45.7-47.1% and 53.2-59.7%, respectively, and soil salt decreasing level were little influenced by the hydraulic load, inundation depth varies in some degree, but it was influenced by dry-wet alternative irrigating mode The concentration of soil total nitrogen、organic mass、microbial respire rate, and the reed biomass above ground were increased averagely to 2.17、1.20、1.46 and 1.34 multiple respectively afterirrigation with wastewater, which have complex remediation effects on the coastal saline-alkali wetland, but there are some differences among the different irrigating crafts.

Extraintestinal pathogenic Escherichia coli (ExPEC) is an important zoonotic pathogen that places severe burdens on public health and animal husbandry. There are many pathogenic factors in E. coli. The type VI secretion system (T6SS) is a nano-microbial weapon that can assemble quickly and inject toxic effectors into recipient cells when danger is encountered. T6SSs are encoded in the genomes of approximately 25% of sequenced Gram-negative bacteria. When these bacteria come into contact with eukaryotic cells or prokaryotic microbes, the T6SS assembles and secretes associated effectors. In the porcine ExPEC strain PCN033, we identified four classic rearrangement hotspot (Rhs) genes. We determined the functions of the four Rhs proteins through mutant construction and protein expression. Animal infection experiments showed that the Δrhs-1CT, Δrhs-2CT, Δrhs-3CT, and Δrhs-4CT caused a significant decrease in the multiplication ability of PCN033 in vivo. Cell infection experiments showed that the Rhs protein is involved in anti-phagocytosis activities and bacterial adhesion and invasion abilities. The results of this study demonstrated that rhs1, rhs3, and rh4 plays an important role in the interaction between PCN033 and host cell. Rhs2 has contribution to cell and mice infection. This study helps to elucidate the pathogenic mechanism governing PCN033 and may help to establish a foundation for further research seeking to identify potential T6SS effectors.

Background/Aims A strong correlation between depression and irritable bowel syndrome with diarrhea (IBS-D) has been identified. The aim of this study is to identify the correlations among depression, structural factors, gastrointestinal (GI) and extra-GI symptoms, and efficacy of neuromodulators in patients with IBS-D. Methods Patients meeting the Rome III Diagnostic Criteria for IBS-D were enrolled. The intestinal symptoms and psychological states were evaluated using IBS-specific symptom questionnaires and Hamilton Depression Rating Scale. Results In total, 410 patients with IBS-D were enrolled, 28.8% (118/410) had comorbid depression. Patients with depression did not readily experience improvement in abdominal pain/discomfort after defecation, and had a higher prevalence of passing mucus, overlapping functional dyspepsia, and extra-GI symptoms. The structural factor “mental disorders” significantly correlated with main bowel symptom score and degree of pre-defecation abdominal pain/discomfort. No structural factor significantly correlated with bowel movements or stool form. Patients who had passing mucus, overlapping functional dyspepsia and extra-GI painful symptoms have higher score of “anxiety/somatization.” Patients with sexual dysfunction have higher score of “retardation symptoms.” In total, 28.3% of patients with IBS-D were prescribed neuromodulators. Baseline scores of “anxiety/somatization” and “retardation symptoms” positively correlated with improvement of diarrhea after paroxetine, and “sleep disturbances” positively correlated with improvement of abdominal pain/discomfort and diarrhea after mirtazapine. Conclusions Comorbid depression and higher scores of structural factors might aggravate GI and extra-GI symptoms other than bowel movements and stool form. Structural factors of Hamilton Depression Rating Scale correlated with efficacy of paroxetine and mirtazapine in patients with IBS-D. (J Neurogastroenterol Motil 2020;26:505-513)
Cancer Research Advances Regarding the CKLF-like MARVEL Transmembrane Domain Containing Family
Lu, Jia,Wu, Qian-Qian,Zhou, Ya-Bo,Zhang, Kai-Hua,Pang, Bing-Xin,Li, Liang,Sun, Nan,Wang, Heng-Shu,Zhang, Song,Li, Wen-Jian,Zheng, Wei,Liu, Wei Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.6
The CKLF-like MARVEL transmembrane domain-containing family (CMTM) is a novel family of genes first reported at international level by Peking University Human Disease Gene Research Center. The gene products act between chemokines and the transmembrane-4 superfamily. Located in several human chromosomes, the CMTMs CKLF and CMTM1 to CMTM8 may be unregulated in tumors and act as potential tumor suppressor genes with important roles in the immune, male reproductive and hematopoietic systems. In-depth studies in recent years established a close relation between CMTMs and tumorigenesis and metastasis. The CMTM family has a significant clinical value in diagnosis and treatment of diseases linked to tumors and the immune system.
Microblogging and Social Change in China
( Jia Lu ),( Yun Xi Qiu ) 경남대학교 극동문제연구소 2013 ASIAN PERSPECTIVE Vol.37 No.3
In this article we examine the role of microblogging in the ongoing process of social change in China, focusing on its impacts on the formation of civil society and the public sphere. We identify several important features of Chinese microblogging, including an antiauthoritarian stance, opinion leaders, and organized campaigns. Theoretically, these features reflect two major social processes that are simultaneously taking place in China today: modernization and globalization. Through microblogging, these processes influence each other to achieve three possible consequences of social change: fragmentation, development of civil society and the public sphere, and networked violence. Our analysis indicates the failure of civil society and the public sphere to develop as well as the rise of networked violence.

Hierarchically porous Fe3O4@MgAl–LDH magnetic microspheres were reported as novel efficientadsorbent for the removal of anionic dye from water. The as-prepared microspheres had vertically/slantly/horizontally oriented platelets-coated morphology, and exhibited superb adsorption capacity of813.0 mg/g for Congo red (CR), which was the highest reported value of magnetic adsorbents. Theadsorption kinetics and isotherm of CR on microspheres followed the pseudo-second-order andLangmuir model, respectively, and the adsorption processes were spontaneous and endothermic innature. The adsorbed samples could be regenerated by methanol, and easily magnetically separated fromaqueous solution. The synthesized materials might act as excellent adsorbents for environmentalprocesses.
