1Ursolic acid: An overview on its cytotoxic activities against breast and colorectal cancer cells显示文摘Ursolic acid(UA) is a pentacyclic triterpene of the ursane type. As a common chemical constituent among species of the family Lamiaceae, UA possesses a broad spectrum of pharmacological properties. This overview focuses on the anticancer properties of UA against breast cancer(BC) and colorectal cancer(CRC)that are most common among women and men, respectively. In vitro studies have shown that UA inhibited the growth of BC and CRC cell lines through various molecular targets and signaling pathways.There are several in vivo studies on the cytotoxic activity of UA against BC and CRC. UA also inhibits the growth of other types of cancer. Studies on structural modifications of UA have shown that the –OH groups at C3 and at C28 are critical factors influencing the cytotoxic activity of UA and its derivatives.Some needs for future research are suggested.

2Design and implementation of a leader-follower cooperative control system for unmanned helicopters显示文摘In this paper,we present a full scheme for the cooperative control of multiple unmanned aerial vehicle(UAV)helicopters.We adopt the leader-follower pattern to maintain a fixed geometrical formation while navigating the UAVs following certain trajectories.More specifically,the leader is commanded to fly on some predefined trajectories,and each follower is controlled to maintain its position in formation using the measurement of its inertial position and the information of the leader position and velocity,obtained through a wireless modem.More specifications are made for multiple UAV formation flight.In order to avoid possible collisions of UAV helicopters in the actual formation flight test,a collision avoidance scheme based on some predefined alert zones and protected zones is employed.Simulations and experimental results are presented to verify our design.Ben YUN Ben M.

3去卵巢老年大鼠软骨退变与E_2、MMP-13、TNF-α的相关性显示文摘目的探讨去卵巢老年大鼠雌激素下降与软骨退变的相关性。方法 24只6月龄雌性SD大鼠按数字表法随机分为对照组、去卵巢组和去卵巢+跑步组各8只。对照组常规饲养,去卵巢组行双侧卵巢切除术,去卵巢+跑步组行双侧卵巢切除术合并疲劳训练。5周后处死,取左侧膝关节石蜡包埋,行HE染色、免疫组化分析、膝关节软骨Mankin评分,右侧膝关节抽取关节液检测TNF-α含量,取血清检测E_2含量。结果 (1)膝关节切片HE染色显示:与对照组比较,去卵巢组与去卵巢+跑步组膝关节软骨均出现缺损,其中去卵巢+跑步组缺损最重;(2)与对照组比较,去卵巢组和去卵巢+跑步组mankin评分、膝关节MMP-13表达、关节液TNF-α浓度均明显提高(P<0.01),血清E_2浓度明显降低(P<0.01),且以去卵巢+跑步组变化最为显著。结论老年大鼠雌激素的下降与软骨退变具有一定的相关性。KHOO YEW LEE 周逸 张俐 2018福建中医药2018,49,2:3
4绿茶提取物EGCG治疗卵巢癌分子机制的生物信息学分析显示文摘目的:通过生物信息学方法分析绿茶提取物茶多酚—表没食子儿茶素没食子酸酯(EGCG)治疗卵巢癌的分子机制。方法:在PubChem数据库中查找EGCG活性靶蛋白,在Gene数据库中查找卵巢癌相关基因,运用Ingenuity Pathway Analysis(IPA)软件,构建二者的信号通路和分子网络并进行分析。结果:二者共同作用的通路有232条,排在前面的主要是癌症分子机制通路、炎症反应通路、细胞因子信号通路;共同的分子网络有6个,也主要体现在'细胞死亡与生存,细胞生长、增殖,细胞发育,DNA的复制、重组、修复,转录后修饰与调控,蛋白质合成'等生物学功能上。预测EGCG作用于卵巢癌的靶点主要为Jun、FADD、NF-κB、BCL2、HIF1α和MMP。结论:EGCG可通过干预卵巢癌相关癌症分子信号通路上多个靶点发挥治疗卵巢癌的作用。张牧 宋新强 张雅芳 陈磊 Lee Yew Mun 2018现代肿瘤医学2018,26,10:3
5推拿配合整脊治疗椎动脉型颈椎病的研究概况显示文摘颈椎是人体脊柱活动量最大的关节,纤维环的松弛与颈椎间盘的退变失稳造成颈椎在特定空间及时间范围内发生异常。颈部的肌肉拉伸或收缩持续时间过久容易导致损伤,损伤的软组织使椎体的整体生理曲度改变或小错位而导致颈椎病。其中,椎动脉型颈椎病是颈椎退行性改变后,椎骨内外平衡失稳并压迫.KHOO YEW LEE 周逸敏 张俐 2019福建中医药2019,50,1:3
6中药治疗湿热蕴结型痛风性关节炎研究现状显示文摘痛风是人体嘌呤代谢紊乱、超负荷而导致尿酸盐结晶形成并沉积于皮下、关节、骨骼等而引发局部急、慢性炎症和组织损伤的一种常见病变,其与高尿酸血症直接相关[1]。中医认为该病是因为湿热蕴结于关节处导致其无法排出而发病[2]。饮食过度、肥甘厚腻的生活方式,导致痛风发病率逐渐递增,痛风病患者的生活质量下降[3]。《中医病证诊断疗效标准》中将痛风分为湿热蕴结型、肝肾阴虚型、痰浊阻滞型、瘀热阻滞型4型[4],KHOO YEW LEE 周逸敏 张俐 2018福建中医药2018,49,1:3
7Negligible risk of inducing resistance in Mycobacterium tuberculosis with single-dose rifampicin as post-exposure prophylaxis for leprosy显示文摘Post-exposure prophylaxis(PEP)for leprosy is administered as one single dose of rifampicin(SDR)to the contacts of newly diagnosed leprosy patients.SDR reduces the risk of developing leprosy among contacts by around 60%in the first 2–3 years after receiving SDR.In countries where SDR is currently being implemented under routine programme conditions in defined areas,questions were raised by health authorities and professional bodies about the possible risk of inducing rifampicin resistance among the M.tuberculosis strains circulating in these areas.This issue has not been addressed in scientific literature to date.To produce an authoritative consensus statement about the risk that SDR would induce rifampicin-resistant tuberculosis,a meeting was convened with tuberculosis(TB)and leprosy experts.The experts carefully reviewed and discussed the available evidence regarding the mechanisms and risk factors for the development of(multi)drug-resistance in M.tuberculosis with a view to the special situation of the use of SDR as PEP for leprosy.They concluded that SDR given to contacts of leprosy patients,in the absence of symptoms of active TB,poses a negligible risk of generating resistance in M.tuberculosis in individuals and at the population level.Thus,the benefits of SDR prophylaxis in reducing the risk of developing leprosy in contacts of new leprosy patients far outweigh the risks of generating drug resistance in M.tuberculosis.Liesbeth Mieras Richard Anthony Wim van Brakel Martin W.Bratschi Jacques van den Broek Emmanuelle Cambau Arielle Cavaliero Christa Kasang Geethal Perera Lee Reichman Jan Hendrik Richardus Paul Saunderson Peter Steinmann Wing Wai Yew 2016Infectious Diseases of Poverty2016,5,1:2
