Facile fabrication of sulfonated porous yeast carbon microspheres through a hydrothermal method and their application for the removal of cationic dye.

Water pollution containing dyes become increasingly serious environmental problem with the acceleration of urbanization and industrialization process. Renewable adsorbents for cationic dye wastewater treatment are becoming an obstacle because of the difficulty of desorbing the dye from the adsorbent surface after adsorption. To overcome this dilemma, herein, we report a hydrothermal method to fabricate sulfonic acid modified yeast carbon microspheres (SA/YCM). Different characterization techniques like scanning electron microscopy, FTIR spectroscopy, and X-ray diffraction have been used to test the SA/YCM. Decorated with sulfonic acid group, the modified yeast carbon microspheres possess excellent ability of adsorbing positively charged materials. The removal rate of Methyl blue (MB) by renewable adsorbent SA/YCM can reach 85.3% when the concentration is 500 mg/L. The SA/YCM regenerated by HCl showed excellent regeneration adsorption capacity (78.1%) after five cycles of adsorption-desorption regeneration experiment. Adsorption isotherm and kinetic behaviors of SA/YCM for methylene blue dyes removal were studied and fitted to different existing models. Owing to the numerous sulfonic acid groups on the surface, the SA/YCM showed prominent reusability after regeneration under acidic conditions, which could withstand repeated adsorption-desorption cycles as well as multiple practical applications.

Novel fabrication of hydrophobic/oleophilic human hair fiber for efficient oil/water separation through one-pot dip-coating synthesis route.

Frequent oil spill accidents and industrial wastewater discharge has always been one of the most severe worldwide environmental problems. To cope with this problem, many fluorine-containing and high-cost materials with superwettability have been extensively applied for oil-water separation, which hinders its large-scale application. In this work, a novel human hair fiber (HHF)-polymerized octadecylsiloxane (PODS) fiber was fabricated with a facile one-pot dip-coating synthesis approach, inspired by the self-assembly performance and hydrophobicity of OTS modification. The benefits of prominent hydrophobic/lipophilic behavior lie in the low surface energy, and a rough PODS coating was rationally adhered on the surface of HHF. Driven solely by gravity and capillary force, the HHF-PODS showed excellent oil/water separation efficiency (> 99.0%) for a wide range of heavy and light oil/water mixtures. In addition, HHF-PODS demonstrated durability toward different harsh environments like alkaline, acid, and salty solutions.

Emodin alleviated kidney damage in high fat diet induced obese mice / 中华内分泌代谢杂志

Objective To explore the protective effect of emodin on kidney damage in high-fat diet-induced obese mice. Methods Male C57bl/ 6 mice were divided into groups according to diet and treatment. Collagen Ⅳ(Col4), phosphatidylinositide 3-kinase(PI3K), phosphorylated phosphoinositol 3-kinase(p-PI3K), protein kinase (Akt), and phosphorylated protein kinase(p-Akt) were measured by Western blotting method. Results Col4 was increased, while p-PI3K and p-Akt were decreased in kidney tissue in high-fat diet-induced obese mice. However, there was lower level of Col4, but higher levels of p-PI3K and p-Akt in kidneys. Conclusion Kidney damage of high-fat diet-induced obese mice seems to be alleviated by emodin via improving insulin sensitivity.

Association between adverse obstetric outcomes and abnormal maternal serum markers in the second trimester screening / 上海交通大学学报（医学版）

Objective · To evaluate the association between the abnormal maternal serum markers of alpha fetoprotein (AFP), human chorionic gonadotrophin (hCG) and unconjugated estriol (uE3) in the second trimester screening and the adverse obstetric outcomes other than trisomy 21 (T21),trisomy 18 (T18) and open neural tube defects (ONTD), and to provide local data for supporting evidence based clinical managements. Methods · A retrospective cohort study was performed in the women who received second trimester maternal serum screening in the International Peace Maternal and Child Health Hospital between 2012 and 2014, with naturally conceived singleton pregnancies. Obstetric outcomes were followed up by searching electronic medical records within the hospital. Abnormal level of marker was defined as a MOM value ≥ 99th (P99) or ≤ 1st percentile (P1) of the overall screened population. Incidence of an adverse obstetric outcome was compared between the groups with abnormal markers and the control with all markers in normal. Results · ① A total of 25616 pregnancies were included in this study, in which 4526 were identified as having various adverse obstetric outcomes. Among them 4143 pregnancies were with isolated and 383 pregnancies were with co-occurring two or more adverse outcomes. ② When compared to pregnancies with normal levels of all three serum markers, pregnancies with decreased AFP or decreased hCG did not show associations with any adverse obstetric outcomes. However, pregnancies with increased AFP, increased hCG or decreased uE3 were at increased risk for a variety of abnormal pregnancy outcome. In 18 pregnancies with an outcome of fetal chromosomal abnormalities other than T21 and T18, 9 presented with either increased AFP, increased hCG or decreased uE3, with relative risk ratios of 13.33、35.00 and 59.00, respectively. ③ The performance of those markers tended to be improved in a subset of adverse obstetric outcomes, including low birth weight

Clinical and experimental pathology of Moyamoya disease / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To investigate the etiology, pathology, and mechanism of pathogenesis of Moyamoya disease.</p><p><b>METHODS</b>A total of 15 human autopsies were analyzed. In addition, in order to create an animal model of the disease, 21 Japanese rabbits were divided randomly into two groups and subjected to injections of horse serum either intravenously or locally in the area of the sympathetic ganglia. Pathological and immunohistochemical characteristics were observed.</p><p><b>RESULTS</b>The pathological features of the autopsies and the animal models both involved intima hyperplasia and stenosis or even occlusion of the lumen in the terminal ends of the internal carotid artery and the anterior and middle cerebral arteries. Disconnections or even breakages of the inner layer of the lumen were also observed, without an obvious inflammatory response. Hyperplasic smooth muscle cells of the medial membrane had extended inward through broken portions of the internal elastic lamina, with intima cell hyperplasia resulting in lumen stenosis. The hyperplastic vascular walls were positive for IgG and IgM.</p><p><b>CONCLUSIONS</b>The etiology of Moyamoya disease may involve allergic angiitis. A possible mechanism is that proximal portions of the circle of Willis first develop chronic stenosis or occlusion, leading to compensatory small vessel proliferation, which perforates into the cerebral parenchyma.</p>
