Table 5 Correlation of Cobb angle of rat lumbar spine in anteroposterior radiograph with related genesConclusions:(1)Chirismus and tetracycline have a similar therapeutic effect to relieve the lumbar disc degeneration of rats via inhibiting the expression of COL-1a.

7MMP-3的表达量正常组最低，P.01，与其它各组差异有显著意义；对照组MMP-3的表达量较手法组与四环素组高，P.01，故与该两组间差异有显著意义；手法组MMP-3的表达量比四环素组高，P.05，故两组间差异有意义。

The mc2155 carrying pMind-glmU-AS was induced by different concentration of tetracycline, and GlmU protein was detected in the mc2155 carrying pMind-glmU-AS by Western blotting. The results showed that tetracycline of 20ng/ml has obviously inhibited the growth rate of mc2155 carrying pMind-glmU-AS, but the amount of GlmU protein did not change compared to that of uninduced mc2155 carrying pMind-glmU-AS.

glmU反义RNA的诱导表达与GlmU蛋白的检测分别用5 ng/ml、10 ng/ml和20 ng/ml的四环素诱导携带pMind-glmU-AS表达载体的mc~2155菌株表达反义RNA，绘制细菌生长曲线，结果表明20 ng/ml浓度的四环素可抑制mc~2155/pMind-glmU-AS的生长，但Western Blotting分析结果显示经四环素诱导和未诱导的mc~2155/pMind-glmU-AS中，GlmU蛋白表达量无明显的变化。

Tetracycline showed a good regulation on the expression of P37 protein, which was not detectable without tetracycline induction.

四环素对其表达显示出明显的调控作用，不加四环素的细胞不表达P37蛋白。

Soil had very great buffer on tetracycline kind antibiotics, the buffer ability on oxytetracycline was higher than tetracycline with the concentration of antibiotic.

土壤对四环素类抗生素有很大的缓冲性，对土霉素的缓冲能力高于四环素。

A method for simultaneous determination of oxytetracycline, tetracycline, chlortetracycline and choramphenicol in seafood was successfully developed using high performance liquid chromatography with ammonium acetate/water and acetonitrile as the mobile phase. The results showed that the four antibiotics were well separated under the optimum conditions, with the limits of detection being 32 μg/kg for oxytetracycline, 15 μg/kg for tetracycline, 23 μg/kg for chlortetracycline, and 19 μg/kg for choramphenicol. The recovery of standard additions was 76~92% and the relative standard deviation was 0.8-4.5%. The method is rapid, sensitive, accurate and reliable and can be applied in the analysis of antibiotic residues in seafood.

建立了同时检测海产品中土霉素、四环素、金霉素、氯霉素残留的高效液相色谱分析方法，以醋酸铵-醋酸/水缓冲液和乙腈作为流动相，通过二元梯度洗脱，使四种抗生素获得了较好的分离，以基线噪音的3倍计算，土霉素、四环素、金霉素、氯霉素最低检出浓度分别为32μg/kg、15μg/kg、23μg/kg、19μg/kg，在添加浓度范围内，四种抗生素的加标回收率为76~92%，相对标准偏差为0.8~4.5%，该方法快速、灵敏、准确，可靠性高，可用于海产品中抗生素残留的色谱分析。
