The invention discloses a reagent kit and a method for quickly and efficiently detecting the polymorphism of drug-induced skin adverse reaction related genes, and belongs to the technical field of gene detection. The polymorphism of the related genes includes the polymorphism of HLA-B*1502 and HLA-B*5801 genes. The reagent kit comprises sample treatment reagents, PCR (polymerase chain reaction) 8joint management individual-portion premixed and separately packaged gene detection reagents, positive reference substances and a negative reference substance. The sample treatment reagents are used for treating human whole-blood samples, the positive reference substances are gene plasmid DNA (deoxyribonucleic acid) and internal reference plasma DNA, and the negative reference substance is ultrapure water without target genes or internal reference genes. The reagent kit and the method have the advantages that specific amplification and real-time detection and analysis are carried out by specific amplification primer pairs and MGB-NFQ (minor groove binder-non-fluorescent quencher) fluorescent probes which are designed according to target gene sequences, accordingly, the detection specificity and sensitivity can be enhanced, and variation of desired genes can be accurately, specifically and sensitively detected from the polymorphism of thousands of allelic genes of HLA-B.

The present invention provides methods for determining an individual's risk of developing Alzheimer's disease. The methods include collecting a biological sample from an individual; genotyping a nucleic acid in the biological sample for a genetic polymorphism in a RAB10 gene or a SAR1A gene or both the RAB10 gene and the SAR1A gene, and determining from the genotyping a decreased risk of developing Alzheimer's disease when the genetic polymorphism in the RAB10 gene or the SAR1A gene or both the RAB10 gene and the SAR1A gene is present. The methods may also include determining the presence of SNP rs 142787485 which comprises an adenine (A) to guanine (G) change in the 3′ untranslated region of the RAB 10 gene, and/or determining the presence of SNP rs7653 which comprises a cytosine (C) to thymine (T) change in the 3′ untranslated region of the SAR1A gene.

The invention provides InDel markers for identifying purple tea tree varieties, and a combination and application of the InDel markers. The InDel markers include the InDel marker 1 and the InDel marker 2. InDel fingerprints are utilized for identifying four purple tea tree varieties including the ziyan variety, the zixian variety, the zihong variety and the zijuan variety, and 30 pairs of InDel primers are selected from whole tea tree genomes to be subjected to polymorphic screening. An identification process mainly includes the steps of: extracting total DNA of tea trees, designing the primers, conducting PCR amplification, and carrying out allele polymorphism statistics; and finally, two pairs of InDel primers (SEQ ID NO:5-8) are determined to serve as core primers for variety identification. By adopting the InDel markers, the four purple tea tree varieties can be effectively and completely distinguished, and therefore, not only can protection and popularization of the purple tea tree varieties be promoted, but also a simple, rapid, accurate and efficient identification method is provided for the four purple tea varieties which are easy to confuse on the market.

The invention discloses a kit for detecting oxidation resistance genotype of human skin and a methodthereof. The invention adopts multiple PCR amplification and electrophoresis methods to analyze and identify six allele polymorphism (SNP) sites in four genes (NQ01, SOD2, NFE2L2 and GPX1). The method comprises the following steps: a) collecting exfoliated cells in the oral cavity of a testee, and storing the collected exfoliated cells in a collection card or extracting DNA nucleic acid from a blood sample; b) adding a saliva collection card sample or an extracted DNA sample of a testee into a reaction system, and carrying out PCR amplification; c) running an amplification program; and d) carrying out electrophoretic analysis on the amplification product, and interpreting according to a peak pattern graph. According to the invention, SNP of a plurality of genes related to a testee can be synchronously detected, and simplicity, high efficiency and specificity of detection are realized. Through the analysis, reference information of the skin antioxidant capacity of the testee can be provided for the testee.

The invention relates to a method for detecting behcet diseases. The method comprises the steps that data of 15 behcet disease HLA allelic gene polymorphism types is collected, a behcet disease HLA allelic gene polymorphism database is established, according to the 15 behcet disease HLA allelic gene polymorphism types in the behcet disease HLA allelic gene polymorphism database, 15 behcet diseaseHLA typing specific primers are designed, after a to-be-detected DNA sample is extracted, the behcet disease HLA typing specific primers and the to-be-detected DNA sample are added into a sequencing chip, amplification and sequencing are performed on the to-be-detected DNA sample, the HLA type of the to-be-detected DNA sample in a sequencing result is compared with the 15 behcet disease HLA allelic gene polymorphism types in the database, a comparison result is judged by a physician, and the auxiliary diagnosis of the behcet diseases is achieved.

The use of markers that participate in inflammatory processes and are associated cytokines in the diagnosis, treatment or prophylaxis of diseases is disclosed. Specifically, cytokines are used to diagnose or treat non-neoplastic or non-leukaemic diseases such as autoimmune diseases or neurodegenerative disorders by the process of taking a DNA bearing sample from a subject animal and analysing the sample to determine the allelic variants present at one or more of the SNP loci at positions −1082, −819 and −592 of the gene encoding IL-10. A method of treating Alzheimer's disease, autoimmune diseases or other neurodegenerative disorders is disclosed by modulating, that is augmenting or decreasing, the function of a gene having one of the allelic polymorphisms of IL-10. IL-6 inhibitors and IL-10 promoters can be used in the manufacture of a medicament for the treatment of prophylaxis of Alzheimer's disease.
