鳋科（寄生桡足类）胸板的扫描电镜比较研究

本文利用扫描电镜观察了我国鳋科的5个属的种类。首次发现在它们的胸部腹面游泳足连接板之下均有一板状结构,其形状与栉齿的着生情况在不同属之间存在着明显的差异,同属不同种之间也不尽相同,这是一个过去未曾被注意过的结构,权且称之为胸板。它是一个独立的结构,不与连接板相连。胸板上的栉齿从形态-功能-适应三位一体分析,它与附着寄主有夭,以免被水流冲走,与无栉齿的相比,应是一个进步性状。     

Cytochemical Localization of Reserves during Seed Development in Arabidopsis thaliana under Spaceflight Conditions

Successful development of seeds under spaceflight conditionshas been an elusive goal of numerous long-duration experimentswith plants on orbital spacecraft. Because carbohydrate metabolismundergoes changes when plants are grown in microgravity, developingseed storage reserves might be detrimentally affected duringspaceflight. Seed development in Arabidopsis thaliana plantsthat flowered during 11 d in space on shuttle mission STS-68has been investigated in this study. Plants were grown to therosette stage (13 d) on a nutrient agar medium on the groundand loaded into the Plant Growth Unit flight hardware 18 h priorto lift-off. Plants were retrieved 3 h after landing and siliqueswere immediately removed from plants. Young seeds were fixedand processed for microscopic observation. Seeds in both theground control and flight plants are similar in their morphologyand size. The oldest seeds from these plants contain completelydeveloped embryos and seed coats. These embryos developed radicle,hypocotyl, meristematic apical tissue, and differentiated cotyledons.Protoderm, procambium, and primary ground tissue had differentiated.Reserves such as starch and protein were deposited in the embryosduring tissue differentiation. The aleurone layer contains alarge quantity of storage protein and starch grains. A seedcoat developed from integuments of the ovule with gradual changein cell composition and cell material deposition. Carbohydrateswere deposited in outer integument cells especially in the outsidecell walls. Starch grains decreased in number per cell in theintegument during seed coat development. All these characteristicsduring seed development represent normal features in the groundcontrol plants and show that the spaceflight environment doesnot prevent normal development of seeds in Arabidopsis.

kar交配法转移YACs至新宿主的研究

利用改进的kar交配法,将一个含有340kb人基因组DNA的YAC片段的供体酵母菌株YAC23与受体菌株YLB504进行交配,以选择平板对所形成的候选YAC导入菌进行筛选。经PCR分析,候选YAC导入菌在404bp处有一个扩增带,即具有受体菌株的交配型(MAT α)。进一步用脉冲电泳进行核型鉴定,证实YACs己成功地进入受体,实现了YACs从一个宿主到另一个宿主之间的转移。     

S－美芬妥英羟化代谢多态性的分子机制研究进展

人群中存在着Ｓ－美芬妥英羟化代谢多态性。从人肝微粒体已分离出Ｓ－美芬妥英羟化酶。在基因克隆研究中已分离出与该羟化酶活性有关的Ｐ４５０ｃＤＮＡ,属Ｐ４５０２Ｃ１９。最近报道,人肝中Ｐ４５０２Ｃ１９的含量和催活Ｓ－美芬妥英羟化活性密切相关,其弱代谢者主要由于ＣＹＰ２Ｃ１９的外显子５单碱基对（Ｇ→Ａ）的变异,使核苷酸序列错位而产生无功能的Ｐ４５０蛋白的结果。     

石榴小爪螨在樟树上的生物学特性和种群动态

石榴小爪螨 Oligonychus punicae(Hirst)是鳄梨、石榴、葡萄和樟树上的重要害螨。在江西弋阳以卵越冬,属兼性滞育,发育起始温度为7.9℃,完成一代的有效积温为205.5日度。室内生命表结果是,在 20.7℃和28℃下r_m分别为0.42和0.44,R₀为37.58和19.07。一年内种群数量动态的总趋向是,在干旱季节食螨瓢虫和一种钝绥螨是石榴小爪螨数量增长的限制因子,而在雨季,特别是连续暴雨就成为螨量急剧下降的主导因素。

MMF联合泼尼松治疗成人特发性膜性肾病的疗效及安全性研究

目的:探究吗替麦考酚酯(MMF)联合泼尼松(Pre)治疗成人特发性膜性肾病(IMN)的疗效及安全性。方法:选取2015.06-2017.06我院收治的102例行IMN患者列为研究对象,将患者按随机数字表法以1:1比例分为对照组与观察组,每组各51例,对照组患者使用Pre进行治疗,观察组患者使用MMF+Pre进行治疗,治疗12个月。比较两组治疗12个月后疗效,治疗前、治疗后6个月及12个月后肾功能相关指标[24 h尿蛋白定量(24 h UP)、血清胱抑素C(CysC)、血清尿素氮(BUN)、血清肌酐(Scr)、血清白蛋白(Alb)]、脂代谢指标[总胆固醇(TC)、甘油三酯(TG)],并记录用药间期出现的药物不良反应。结果:治疗12个月后,研究组患者总有效率为90.20%,显著高对照组74.51%(P0.05);治疗6个月、12个月后,两组患者24 h UP、Cys C、TC、TG水平较治疗前均依次显著下降而Alb水平显著上升(P0.05),且观察组上述指标与同期对照组对比差异显著(P0.05);而两组BUN和Scr水平较治疗前差异不显著(P0.05),两组对比无统计学意义(P0.05)。治疗期间,观察组患者药物不良反应率为11.76%,显著低于对照组27.45%(P0.05)。结论:应用MMF联合泼尼松治疗成人IMN疗效更佳,可显著改善患者肾功能,并改善患者脂代谢,药物方案安全性较高,具有较高应用价值。
