Abstract: An anti-pollution test device and a method for rapid test of nucleic acid amplifications, and a use. The anti-pollution test device includes a test portion and a mixing reaction chamber, where the mixing reaction chamber includes: a reaction chamber body, a reaction chamber cover, a channel and a mixing reaction portion. The test portion includes a test inner core, a test kit, a transparent observation window, a flow guide device, and the flow guide device including: a flow guide tube and a flow guide component. One end of the flow guide component is connected to the flow guide tube, one end of the flow guide component is connected to the test inner core, to guide a mixed solution of a hybridization solution and a sample to the test inner core. The test inner core displays a final test result in an area corresponding to the transparent observation window.

Abstract: The present invention discloses an application of an exosome-related microRNA in preparing a marker or diagnosis and prediction of lung cancer and a kit, and develops a PCR platform-based two-step detection kit for miRNA, which has the outstanding advantage in the aspect of auxiliary diagnosis of lung cancer by the combined use of up-regulated and down-regulated molecular markers, and has the sensitivity as low as lcopy/?L, greatly improving the detection accuracy. In addition, the isothermal amplification-based one-step detection system for miRNA developed by the present invention is faster and more convenient, which can greatly improve detection efficiency and reduce detection costs.

Abstract: This invention provides the applications of CST1 gene and its splice variants (sequence shown in SEQ ID No.48) and cystatin SN protein coded by CST1 gene (sequence shown in SEQ ID No.52) for the predictions and diagnoses of human breast cancers. The invention can be used for the diagnosis of breast cancer and breast cancer metastasis, for the analysis for the susceptibility for breast cancer, for the evaluation of the treatments, medicine, efficacy and prognosis for original or metastatic breast cancer patients, and for the risk assessment for breast cancer or its metastasis. The methods described in this invention are of significant sensitivity, specificity and reliability. The invention provides the capturers of CST1 gene, its splice variants and cystatin SN and their applications in manufacturing diagnostic reagents, kits and chips for breast cancers. The diagnostic reagents, kits and chips for breast cancer are included in this invention.

Abstract: In this invention, we disclosed and documented the applications of CST4 gene, mRNA of CST4, cDNA of CST4 splices, the corresponding amplicon of CST4-specific primers, cystatin S protein coded by CST4 gene and epitope peptide of CST4 in the diagnosis and prediction of colorectal cancer, and the detection method and testing kits of the above. This invention shall be applied in the diagnosis, dynamic monitoring and progression prediction of colorectal cancer. Methods mentioned in this invention features high sensitivity and reliability, which was verified by large-scale trial.
