Due to the limitation of traditional technology, there are some problems and deficiencies in the existing methods of food microbial detection. In order to meet the requirements of future development, it is necessary to promote the application of enzyme-linked immunosorbent assay in the detection of food microorganisms. In this paper, the application value of enzyme-linked immunosorbent assay (ELISA) was discussed by analyzing the technical requirements of food microorganism detection. Based on this, this paper studies the application characteristics and key points of enzyme-linked immunosorbent assay (ELISA) in combination with the characteristics of technological development of the times. These studies are of great significance to the application of enzyme-linked immunosorbent assay (ELISA) and the development of food microbial detection.

简介：摘要：目的 探究在血透病人肾性骨病治疗中使用树脂吸附联合血液透析的作用。方法 选取2018年1月~2019年12月我院收治的100例慢性肾功能衰竭患者作为研究对象，采取随机分组方法根据患者入院日期单双号分为对照组（50例）和观察组（50例），对照组仅使用血液透析治疗，观察组于对照组基础上配合使用树脂吸附治疗，对比两组患者治疗效果以及治疗前后血液指标（iPTH、P3+、SCr、Hb）水平。结果 观察组治疗总有效率高于对照组，观察组治疗后iPTH、P3+、SCr水平均低于对照组（p0.05）。结论 在血透病人肾性骨病治疗中，使用树脂吸附联合血液透析治疗效果良好，可有效改善患者血液指标水平，促进患者的身体恢复。

简介：【摘要】目的：探究静电吸附消毒与紫外线消毒在空气消毒中的效果以及影响因素。方法：选取我院一样的 20间病房，将其分为 A、 B两组，每组 10间病房，分别实施 3次消毒工作，其中 A组病房实施静电吸附消毒， B组实施紫外线循环风空气消毒，两组消毒机同时工作 1h，并在结束工作后立即对病房内的细菌数进行统计，此后 1h、 2h和 4h时再对房间内细菌数量进行统计，对比两组的细菌增长量。结果：消毒结束后，紫外线循环风空气消毒方式与静电吸附式消毒都具有较好的消毒效果，但总体来说，紫外线循环风空气消毒方式要更好一些；消毒机停止工作以后分别于 1h、 2h以及 4h对房间内的细菌菌落数据进行对比， B组的细菌菌落数量明显少于 A组，由此可见紫外线循环风空气消毒方式消毒效果更好，且 P＜ 0.05。结论：在病房内使用循环风紫外线和静电吸附式空气消毒机都能够对病房进行消毒，但相对来说紫外线循环风空气消毒机的消毒时效更长一些，效果也更好。

简介：[摘要 ] 目的 比较化学发光免疫分析技术（ CLIA）和酶联免疫吸附试验（ ELISA）在乙肝病毒血清学检验中的应用价值。 方法 选取 2017年 1月～ 2019年 6月间我院收治的 80例疑似乙型肝炎患者，采用 CLIA法、 ELISA法对乙肝病毒血清学指标进行检测，以实时荧光定量 PCR检验结果作为参照，分析 CLIA法、 ELISA法對乙肝的诊断结果。 结果 ELISA法对乙肝的诊断灵敏度、特异度、准确性分别为 91.84%、 93.55%、 92.50%， CLIA法分别为 93.88%、 96.77%、 95.00%，二者比较均无统计学差异（ P均 >0.05）。 CLIA法、 ELISA法对乙肝的诊断结果与实时荧光定量 PCR之间具有良好一致性， Kappa均 >0.7。 CLIA法对 HBsAg、 HBeAg、 HBeAb的阳性检出率高于 ELISA法（ P<0.05），而在 HBsAb、 HBcAb阳性检出率比较无统计学差异（ P>0.05）。 结论 CLIA法、 ELISA法对乙型肝炎的诊断效果均较好，而在乙肝病毒血清学标志物检验中， CLIA法的检验准确性高于 ELISA法。  　　 [关键词 ] 乙型肝炎；乙肝病毒；血清学检验；化学发光免疫分析法；酶联免疫吸附试验  　　 [Abstract] Objective To compare the application value of chemiluminescence immunoassay（ CLIA） and enzyme-linked immunosorbent assay（ ELISA） in serological testing of hepatitis B virus. Methods From January 2017 to June 2019， 80 patients with suspected hepatitis B who were admitted to our hospital were selected.

There was no statistically significant difference between the two methods（ P>0.05 for all） . CLIA method and ELISA method for the diagnostic results of hepatitis B were well consistent with real-time fluorescence quantitative PCR（ Kappa>0.7 for all） . The positive detection rate of HBsAg， HBeAg and HBeAb by CLIA was higher than that of ELISA（ P<0.05）， and the difference of positive detection rate of HBsAb and HBcAb was not statistically significant（ P>0.05） . Conclusion CLIA method and ELISA method are favorable for the diagnosis of hepatitis B. In the hepatitis B virus serological marker test， the test accuracy of CLIA is higher than that of ELISA.  　　 [Key words] Hepatitis B； Hepatitis B virus； Serological testing； Chemiluminescence immunoassay（ CLIA）； Enzyme-linked immunosorbent assay（ ELISA）
