Results: Of 59 superficial bladder cancer samples, sensitivity tests were successfully performed in 45 samples, and the others failed, the successful rate was 76.3%.Diversity of inhibiting rates of antitumor drugs was observed in samples from different individuals. Except MTX in stage of G1 and G3, no correlation has been found between the phenotype of sensitivity assay and the pathological grade and stage. Sensitivity and mean inhibiting rates of antitumor drugs in the primary group were notedly higher than that in the recurrent group.The combination of two therapy agents, which have different mechanisms or different cell-cycle targets, showed significantly more sensitivity and higer mean inhibiting rates than single one in superficial bladder cancer in different individuals.

结果：14例失败，45例获得成功，总体可评价率为76.3％，不同抗癌药物对不同个体膀胱癌的抑制率存在明显差异；除MTX对膀胱癌G1和G3级平均抑制率差异有统计学意义外，其它抗癌药物对不同个体膀胱癌细胞的平均抑制率与膀胱癌的病理分级、分期均无关；抗癌药物对初发膀胱癌的敏感率和平均抑制率均高于复发膀胱癌；两种不同作用机制的抗癌药物联合应用对不同个体膀胱癌细胞的敏感率和平均抑制率均高于单一药物，二者敏感率和平均抑制率差异有统计学意义。

So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.

According to the change of color of TMB, we divided maturation into three phases. The result showed that the germination ratio of TMB affected by difference maturation. And the difference had high relationship with the species, that say genotype of Amorphophallus Blume could affect the storage.

本实验将这个过程分为3个阶段，对不同采收时期的微球茎进行储藏及萌发研究，结果表明，不同采收期的微球茎，储藏后的萌发率具有较大的差异，而且这种差异与魔芋种具有较大的相关性，这种差异与其保水性能有关。

objective to evaluate the role of mr perfusion weighted imaging in preoperation diagnosis of meningiomas.methods mr perfusion weighted images was performed in 47 patients with meningiomas followed by conventional imaging.results the mean rcbv values of angioblastic was the highest in the parenchyma of tumor.the mean rcbv values of malignant group was the lowest.the biggest mean rcbv values among different type meningiomas was statistically significant.the biggest mean rcbv values between benign and malignant group meningiomas was statistically significant,but not in the peri-tumor edema.conclusion the rcbv values were useful in the preoperative differentiation diagnosis of different types of meningiomas.those in the peri-tumor edema were useless in the preoperative differentiation diagnosis of different types of meningiomas.

目的 探讨磁共振灌注成像技术对脑膜瘤术前分型及良恶性鉴别的临床应用价值。方法对47例脑膜瘤病人行mr灌注成像检查，对5种亚型的良性脑膜瘤的mr灌注成像进行分析，并与非典型性及恶性脑膜瘤进行比较。结果血管瘤型脑膜瘤实质部分的rcbv值均数最高，恶性组脑膜瘤的rcbv值均数最低。各亚型间瘤体实质最大rcbv值均数间差异有统计学意义(p＜0.05)，良恶性脑膜瘤实质部分最大rcbv值均数间差异有统计学意义(p＜0.05)。瘤周水肿区的rcbv值均数间差异无统计学意义(p＞0.05)。结论 rcbv值对脑膜瘤术前分型及良恶性鉴别有所帮助，而瘤周水肿区的rcbv值对脑膜瘤分型及良恶性鉴别未显示临床实用价值。

The research displayed that yeasts Genus level can be discerned by agarose gel electrophoresis and polyacarylamide gel electrophoresis, but the latter is more advanced. The Saccharomyces cerevisiae strains ITS-1 sequences are most disalike, few of them are equal completely. The bigger differences are part of base pairs about Poly-T, others are exchanged by single base pair.

研究表明，以酵母菌株的rDNA ITS-1序列进行琼脂糖凝胶电泳，能把菌株分类鉴定到属的水平；采用非变性聚丙烯酰胺凝胶电泳能把部分酿酒酵母菌株分类鉴定到种的水平，区别效果较琼脂糖凝胶电泳有所提高；对rDNA ITS-1序列进行克隆、测序，经序列比对后发现，酿酒酵母属中酿酒酵母菌株的ITS-1序列大多数有差异，差异主要表现在ITS-1序列上游的一段Poly-T碱基上，其它处的差异仅是个别碱基的转换或颠换，ITS-1序列长度分布在360-370bp之间，G+C%含量均在35.3%左右。

We aim to screen and identify the key potential trans-factors during hemoglobin switch. We firstly analyzed differential expression of mRNAs in erythroid induction cultures of CD34+ cells derived from normal umbilical cord blood, adult bone marrow, and bone marrow of a heterocellular hereditary persistence of fetal hemoglobin patient. We identified ZF (HCF-binding transcription factor, Zhangfei) and SH3GLB1(SH3-domain GRB2-like endophilin B1) that had differential expression in the above three cultures. Furthermore, we confirmed the different expression of the above two genes by quantitative real-time PCR.

This thesis chooses Grade 7, Grade 1 of high school and junior as subjects, it proves that the dual-processing theory can make an effective interpretation of individual and age differences in the perspectives of content effect, logic effect, time pressure, self-confidence assessing, logic training and individual cognitive difference according to the different characteristics of the two systems. The research concludes:(1) The subjects in the three grades are all affected by content. The accuracy of the four inferent types about abstract and concrete material increases with age.
