In this work,boron(B)was used to promote Fe^(3+)/peracetic acid(Fe^(3+)/PAA)for the degradation of sulfamethazine(SMT).An SMT degradation efficiency of 9.1%was observed in the Fe^(3+)/PAA system over 60 min,which was significantly increased to 99.3%in the B/Fe^(3+)/PAA system over 10 *** B/Fe^(3+)/PAA process also exhibited superior resistance to natural substances,excellent adaptability to different harmful substances,and good removal of antibiotics in natural fresh water *** mechanism of action of boron for Fe^(3+)reduction was determined using scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),Fourier transform infrared(FT-IR)spectroscopy,density functional theory(DFT)calculations,and electrochemical *** dominant role of^(·)OH was confirmed using quenching experiments,electron spin resonance(EPR)spectroscopy,and quantitative *** radicals(R-O^(·))and Fe(IV)also significantly contribute to the removal of *** calculations on the reaction between Fe^(2+)and the PAA were conducted to further determine the contribution from ^(·)OH,R-O^(·),and Fe(IV)from the perspective of thermodynamics and the reaction *** boron dosages,Fe^(3+)dosages,and initial pH values were also investigated in the B/Fe^(3+)/PAA system to study their effect of SMT removal and the production of the reactive ***(IV)production determined the k_(R-O·+Fe(IV))value suggesting that Fe(IV)may play a more important role than R-O^(·).A comparison of the results with other processes has also proved that the procedure described in this study(B/Fe^(3+)/PAA)is an effective method for the degradation of antibiotics.

Anaphylaxis is a rare,but severe,potentially lifethreatening allergic reaction,which most commonly presents with multi-system involvements,such as cutaneous,cardiovascular,respiratory,gastrointestinal and central nervous system signs and *** can hardly be recognized when occurring in the perioperative period due to the many influencing factors,for example,the cutaneous changes concealed by sterile drapes,inability to describe their symptoms when patients are sedated or anesthetized,and the application of anesthetics leading to sympathetic blockade which presents with blood pressure *** of the above reasons make the identification and immediate treatment of perioperative anaphylaxis difficult and are partially attributable to high mortality.

Chemical Research in Chinese Universities 2007年第2期23卷 176-182页

For making use of Ginseng resources that exhibit an antitumor activity and for finding new anticancer drugs, three new fatty acid ester compounds： 3/β-acetoxy panaxadiol （ Ⅰ ）, 3β-palmitic acid aceloxy panaxadiol （ Ⅱ ） , and 3β-octadecanoic acid aceloxy panaxadiol（ Ⅰ , Ⅱ, and m） were synthesized with panaxadiol, diacetyl oxide, palmityl chloride and stearyl chloride, and their structures were determined via MS, ^13C NMR, IR, TLC, and so on. The molar yields of the three compounds are 75.14%, 79. 08%, and 72. 57%, respectively. Meanwhile, the antitumor activity of the three new panaxadiol fatty acid ester derivatives and panaxadiol was compared by using the method of MTT. Tumor cell used was Vero cell line. Positive control was 5-fu, blank was an RPMI1640 culture medium, negative control was an RPMI1640 culture medium and the solvent for drugs to be tested. Compound Ⅰ has the strongest antitumor activity followed by panaxadiol; compounds Ⅱ and Ⅲ have similar and weakest antitumor activities. furthermore, the antitumor activities of the panaxadiol fatty acid ester derivatives show positive correlation with the concentration of the test group, but show no relationship with the molecular weight of fatty acid. The methods that are used to synthesize the three compounds with high yields and strong antitumor activities are simple and show a great potential for meeting the needs of industrial manufacture of these drugs.

PI-3K/Akt/GSK-3p signaling cascades stimulated by insulin like growth factor-Ⅰcontribute to multiple myeloma cells proliferation and survival

引用

Chinese Medical Journal 2006年第14期119卷 1226-1229页

作者： WANG Meng-chang, fu xue-de LI Man-xiang Department of Hematology First Hospital of Xi＇an Jiaotong University Xi＇an 710061 China Department of Medicine Johns Hopkins Medical Institutions Baltimore MD 21205 USA

Multiple myeloma is characterized by the accumulation of malignant plasma cells in thebone marrow. Significant progress in molecular mechanisms of signaling pathways underlying the survival and/or proliferation of these cells has been achieved. Interleukin 6 （IL-6） is an important cytokine leading to multiple myeloma （MM） cells growth and survival. However, some MM cells isolated from MM patients are poorly responsive to IL-6 stimulation or IL-6 independent. This phenomenon raises the possibility that other growth factors may also be involved in the development of MM. Insulin like growth factor-I （IGF-I） plays an important role in the proliferation of a variety of cell types, in the development and growth of multiple tumors and in the prevention of apoptosis. IGF-I has recently been reported to play such a role in stimulating the MM cells growth, it even induces MM cells proliferation in IL-6 dependent cells, yet the detailed signaling components triggered by IGF-I have not been completely clarified. Thus, the present study are to address the signaling cascades triggered by IGF-I in MM cells.

目的调查中青年维持性血液透析(maintenance hemodialysis,MHD)患者社会回归现状,并探讨其进入透析前后社会功能退化程度的影响因素。方法对2023年6月于山西医科大学第二医院接受MHD的中青年患者,采用横断面及回顾性调查方法收集资料,采集生活质量简表(the kidney disease quality of life questionnaire,short-form version 1.3,KDQOL-SFtm 1.3)、社会功能缺陷筛选量表(social disability screening schedule,SDSS),以透析前后SDSS评分差值的中位数为界将患者分为社会功能退化不明显组和退化明显组。采用单因素分析、二元Logistic回归分析探讨中青年MHD患者社会功能退化的影响因素。结果本研究共纳入MHD患者112例,其中社会回归3级42例(37.50%)、4级70例(62.50%);社会回归4级患者生活质量评分高于3级患者(t=-2.554,P=0.012),而仅在肾病影响(t=2.185,P=0.031)、工作状态(t=3.203,P=0.002)、社交质量(t=2.117,P=0.037)、情感职能(t=2.700,P=0.008)、社会功能(t=2.349,P=0.021)方面有统计学差异。短透析龄(OR=3.031,95%CI:1.192~7.706,P=0.020)、有疲乏症状(OR=7.574,95%CI:1.829~31.367,P=0.005)、合并焦虑和(或)抑郁(OR=3.765,95%CI:1.120~12.658,P=0.032)、较高的社会影响量表得分(OR=1.303,95%CI:1.104~1.537,P=0.002)是中青年MHD患者社会功能退化的独立危险因素。结论中青年MHD患者社会回归及生活质量水平较高;透析龄短、伴有疲乏、有焦虑和/或抑郁状态、病耻感得分高的MHD患者社会功能减退更明显。应高度重视中青年MHD患者的心理和情绪问题。
