ABSTRACT

Objective To explore the clinical value of one-step visualization loop-mediated isothermal amplification(LAMP)in the detection of Mycoplasma pneumoniae(Mp). Methods One-step visualized LAMP,polymerase chain reaction(PCR),and enzyme-linked immunosorbent assay(ELISA)were used to simultaneously detect 108 clinical Mp specimens in children,which included 73 cases of Mp infection diagnosed by PCR and 35 cases of other chronic/acute respiratory tract infections.On the first day of admission,one-step visualization LAMP,PCR(fluorimetric method),and ELISA were used to test the throat swab and serum sample obtained from the same patient,and the Kappa value was calculated.The consistence between LAMP and PCR and that between LAMP and ELISA were compared.On the fifth day of admission,40 patients were resampled and the findings of these three tests on the first day and on the fifth day were compared. Results One-step visualization LAMP had a sensitivity of 100% and a specificity of 94.3%,whereas ELISA had a sensitivity of 65.8% and a specificity of 82.9%.The ratio of Kappa camparing one-step visualization LAMP and PCR was 0.956 and the ratio of Kappa camparing one-step visualization LAMP and ELISA was 0.38.The number of positive specimens detected by LAMP was higher than that by ELISA on the first day. Conclusions One-step visualization LAMP has excellent sensitivity and specificity in detecting early acute Mp infection.It has high consistency with PCR and can be applied to detect Mp.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the clinical efficacy of combination of traditional Chinese medicine and western medicine in the treatment of patient bitten by agkistrodon halys pallas, and the changes in peripheral blood inflammatory factors (hs-PCR, IL-6, TNF-alpha).</p><p><b>METHOD</b>Ninty-eight patients were divided into three groups according to their hospitalization dates: the western medicine group, in which 32 patients were treated with antivenom serum (6 000 U) for five days, once every day; the traditional Chinese medicine group, in which 32 patients were treated with anti pit viper No. 2 concentrated decoction (300 mL), twice to three times every day, for five days; and the combined traditional Chinese medicine and western medicine group, in which 35 patients were treated with the combination of Chinese and Western medicine treatment described above. Then blood samples of all of patients were obtained, and serum factors (hs-PCR, IL-6, TNF-alpha) in peripheral blood were measured by Elisa assay. Another 30 health volunteers were chosen as the normal control group.</p><p><b>RESULT</b>The serum inflammatory factors were significantly higher in all patients of the three groups than that in healthy control before treatment (P < 0.01), and decreased significantly after treatment. In particular, the more remarkable reduction was found in the combined traditional Chinese medicine and western medicine group compared with the western medicine group and the traditional medicine group (P < 0.01). Symptom elimination in the three groups was superior to the western medicine group and the traditional medicine group at the first day and the third day of treatment (P < 0.05, P < 0.01). Total clinical effective rate was 100% in the combined traditional Chinese medicine and western medicine group, 84. 37% in the traditional medicine group and 65.62% in the western medicine group, the clinical effective rate of the combined traditional Chinese medicine and western medicine group was notably superior to that of the western medicine group and the traditional medicine group (P < 0.01).</p><p><b>CONCLUSION</b>The serum inflammatory factors increased significantly in patients bitten by agkistrodon halys pallas. Treatment with the combined traditional Chinese medicine and western medicine can significantly decrease the serum inflammatory factors, and increase clinical effect, with more obvious clinical efficacy compared with the western medicine group and the traditional medicine group.</p>
