Methods: Twenty-four Kkay mice were divided into three groups(n=8):diabetes group,methionine-diet group,folic acid and vitamin B12 treatment group. C57Bl/6 mice were used as controls(C57). Four months later,the mice were sacrificed and their serum levels of Hcy,folic acid and vitamin B12 were measured by fluorescence polarization immunoassay. Pathological changes in kidneys were examined with the periodic acid schiff method with periodic acid-silver methenamine staining under electron microscope. Expression of MMP-9 protein or mRNA was detected by RT-PCR with immunohistochemical staining. Results: Different morphological changes of DN were found in Kkay mice.

Kkay糖尿病鼠随机分3组：糖尿病组、高蛋氨酸组和叶酸、维生素B12组，C57BL/6鼠为对照(C57)，以相应饲料喂养4个月后取材，测定血糖、血同型半胱氨酸、叶酸和维生素B12，以PAS、六氨银染色法光镜下及超微电镜观察各组DN病变，比较各组肾小球硬化指数；以免疫组化和半定量图像分析肾小球MMP-9蛋白表达，并以RT-PCR检测肾脏MMP-9 mRNA水平。

The method on trans fatty acids analysis in food is very important. The effects of methylate sodium, potassium hydroxide, sulfuric acid and boron trifluoride in methanol and their different concentration and dosage on TFA analysis were studied. The chromatographic condition and the influence of time and temperature on the esterifation of TFA using boron trifluoride in methanol were optimized. A method for analyzing TFA were established by GC based on boron trifluoride in methanol and RT-2560(100m×0.25mm×0.2μm) capillary column.

d每天灌胃，14d后形成骨质疏松模型；在实验组中采用RT-PCR方法分别观察灌胃第1、3、5、8、9、10、12、14d肝脏铁调素基因表达变化；要第14d还检测大鼠骨密度、分别脱钙骨切片、观察肝组织切片。

The results showed that the virus isolation and identification could generate considerably reliable results but the procedure was complicated and costed long time; microtomy fluorescent antibody detection was fast, but the specificity was low and needed to exclude the false positive from the results. Sandwich ELISA detection combined the merits of the former two methods, but it generated the false negative results when the samples were in bad preservation. Compared with the others, RT-PCR was fast, high sensitive and especially useful for detecting the CSFV directly from the samples. The specificity could be raised by using the nested-PCR to detect the CSFV from the simples, especially when the simples were in bad preservation.

结果显示，病毒分离鉴定法准确性较高，诊断比较容易，但存在试验步骤繁琐，所需时间长的缺点；荧光抗体检测法所需时间较短，但需要经验比较丰富人员来判定结果，且存在假阳性结果，特异性比较差；RT-PCR检测法具有快速、敏感等优点，特别是样品保存不理想时更有价值，利用套式PCR可以提高检测的特异性；夹心ELISA检测法具有快速、敏感等优点，但在样品保存不理想时会出现假阴性结果。
