对不同肥力水平下晚播小麦开花后地上器官光合产物积累、运转和对产量影响的研究表明，开花后同一天，各地上器官光合产物的积累量均随肥力水平的提高而增加。

CaN Aβ gene silencing can reduce myocardial hypertrophy in cultured cells, si1280 (21bp) of CaN Aβ gene is the most effective target site for siRNA. The method of intrapericardial injection of plasmid, microbubbles and erzymes can improve transfection efficiency of non-viral plasmid with satisfying targeted transfection. But the scope of transfected myocytes is still limited. CaN Aβ shRNA expressing plasmid transfection in vivo by pericardial injection results in decreased CaN Aβ protein expression of small part of myocytes, and CaN Aβ mRNA only shows decreased trend. The dosage of non-viral vector and the parameters of ultrasound energy should be optimized in further study.

结论RNAi技术抑制CaN Aβ基因表达可有效减轻Ald诱导的心肌细胞肥大程度；CaN Aβ基因中si1280(21bp)片段为实现RNAi的更有效片段；微泡+酶类心包腔内注射超声导入的方法可有效改善非病毒载体在体心肌的转染效率，同时具有一定的靶向性，但总的转染范围仍然有限；采用这一方法进一步进行&一肾一夹&心肌肥大模型大鼠在体心肌细胞的CaNAβ的RNAi干预，发现心肌肥大大鼠心外膜下局部心肌细胞CaN Aβ蛋白水平降低，CaN AβmRNA水平虽有下降趋势，但无统计学差异，提示质粒的用量及超声导入的参数有待进一步研究使其优化。

Results indicate that the fatigue life of CA mortar is logarithmically linear with stress levels and the viscoelasticity of CA mortar guarantees a good fatigue performance at -20℃.

结果表明，研制的CA砂浆疲劳寿命对数值与应力水平呈现良好的线性相关性；CA砂浆的抗压强度受环境温度影响较大，相同应力水平条件下，CA砂浆在负温环境中的疲劳寿命低于在常温环境中的，CA砂浆的粘弹性特点保证了CA砂浆在－20℃环境仍具有良好的耐疲劳性能。

Thirty two point six percent (42/129) of menopausetransition women and 18.9％(60/318) of menopause women had breast structure changes,〓=9.26, P＜0.01. The frequency of breast structure changes decreased with decreasing ofserum of 〓 level and increasing of age. Four (4/29, 13.8％) in HRT group had breaststructure changes, which disappeared after discontinuing HRT or reducing the dose of HRTin 3 subjects. Conclusions: Most of normal menstrual women and menopause transitionwomen experienced Mastalgia; Mastalgia occurred in 89.7％ of subjects and lasted forabout 2 M. in the 1-year ccHRT; Image of breast ultrasound changed following menstrualcycle in normal menstrual women; Breast pain and breast structure change may be causedby higher 〓 and P level in luteal phase; The breast structure changes of HRT user weresimilar to that in normal women and were reversible.

大部分正常月经妇女和绝经过渡期妇女有周期性乳房胀疼，绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年中大部分使用者有持续约两个月的乳房胀疼；乳腺体层厚度随体内雌孕激素水平的下降和年龄的增加而逐渐萎缩，绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年后，对乳腺体层的厚度没有明显的影响；超声下乳腺结构改变主要受体内雌孕激素水平的影响，正常月经妇女中1／3的乳腺结构改变具有可逆性，绝经过渡期和绝经后妇女中有一半的乳腺结构改变的特征类似正常月经妇女具有可逆性的乳腺结构改变；绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年后，少数使用者出现的乳腺结构改变可随药物剂量的调整或停药而恢复；对长期HRT使用者仍需加强乳腺的监测，长期HRT对乳腺的影响值得进一步研究。

Methods: Forty mice were divided into four groups randomly:normal group,model group,ligation group and treatment group.The model was made by the method of partly ligating the recta outside the body.The level of endotoxin in blood plasma was measured by dynamic nephelometric method and the content of TNF-a in blood serum was detected by the method of radioimmunity.(2)After the mice were killed,their left lungs were taken out for bronchi-alveoli fluid, then the content of MDA in BALF was tested by TBA method.(3)The vitality of PAM in BALF was countied on the counting set of erythrocyte,and the blue-dyed cellswere counted, then the percentage of PMN was worked out.(4)The pathological features of the mice\'s lung tissue were observed with routine and ultramicro pathological mechanism.

①将40只大鼠随机等分为正常组、模型组、解扎组、治疗组，以体外直肠不全结扎法造模，以动态浊度法检测各组大鼠血浆内毒素水平，放射免疫分析法检测各组血清TNF-α含量；②大鼠处死后，取左肺进行支气管肺泡灌洗，以TBA法测定支气管肺泡灌洗液中丙二醛含量、白蛋白含量及肺表面活性物质水平；③在红细胞计数盘上作BALF中肺泡巨噬细胞活力计数，计数兰染的细胞数，求出死亡百分率；在光镜下计数BALF沉渣200个细胞，计算中性粒细胞所占百分比。

The results showed that: 1 under the hydroponic culture established in this research, the experimental wheat plants grew well andperformed the typical architecture responses when exposed in Pi deprivation. Hemi-qantitative RT-PCR revealed that the transcriptional level of known P response gene changed dramatically; 2 In general the length of wheat root axis and the root/ shoot ratio arose when the Pi supply was deprived, however, the change models differed among different wheat genotypes. The investigation on their molecular basis would offer the useful clue for seeking high phosphorus efficiency protoplasma and gene resources of wheat.

结果表明：1在研究建立的小麦水培体系中，小麦植株生长正常并对磷饥饿胁迫条件做出发育形态建成水平的反应；半定量RT-PCR分析显示在此体系中小麦磷响应基因也在转录水平上产生显著变化；2在水培条件下不同基因型小麦对磷饥饿胁迫的反应总体上表现在根轴长度和根冠比有所提高，但不同基因型小麦的反应特点有差异；对这些反应特征的分子机理的深入分析可为有效筛选磷高效小麦新种质以及发掘磷高效基因资源提供线索。

Correlation analyses on the contents and ratios of endogenous hormones with selfing fertilities showed that selfing fertility was not determined only by one single hormone level, but partially affected by the joint action or balance of several hormones in Nongken58S original and untransformed regenerant controls under long-day. Our results did not support different already proposed hypotheses on one single hormone action in fertility expression of PSGMS rice.

1通过对因受环境低温影响而在长日条件下不育性部分逆转的原始材料和组培再生后代材料的自交结实率与内源激素水平及比值相关性分析表明，农垦58S育性转换并非取决于某种单一激素水平的改变，而可能与多种激素的共同作用和平衡关系有关，从而说明&众说纷纭&的单一激素作用的假说难以成立。
