Study on fluorescence PCR-melting curve method for detecting CYP2C9 and VKORC1 gene polymorphism in Xinjiang Hui population / 国际检验医学杂志

Objective To use the fluorescence PCR‐melting curve method to detect CYP2C9 and VKORC1 gene polymorphism in Xinjiang Hui population ,to analyze their gene distribution and gene mutation frequency ,and to evaluate the clinical applicability of the fluorescence PCR‐melting curve method .Methods The fluorescence PCR‐melting curve method and sequencing method were adopted to contrastively detect CYP2C9*2 ,CYP2C9*3 and VKORC1(‐1639G/A)gene polymorphism .Results Among detected 228 Xinjiang Hui individuals ,199 cases of CYP2C9*1/*1 ,2 cases of CYP2C9*1/*2 ,26 cases of CYP2C9*1/*3 and only 1 case of CYP2C9*3/*3 were detected ,no case of CYP2C9*2/*2 and CYP2C9*2/*3 was detected .Two kinds of allele G and A were detected for VKORC1(‐1639G/A) ,in which VKORC1‐1639G/G type was detected in 2 cases ,VKORC1‐1639G/A type was detected in 39 cases and VKORC1‐1639A/A type was detected in187 cases ,compared with the sequencing method ,the results of the fluorescence PCR‐melting curve method were completely consistent .Conclusion Xinjiang Hui population also has CYP2C9 gene *2 ,*3 loci and VKORC1 gene(‐1639G/A) locus polymorphism ,their occurrence frequency has a certain difference with Xingjiang Uygur and other regional populations ,the adopted fluorescence PCR‐melting curve method used in the gene polymorphism detection can meet clinical detection requirements .

Situation of Administration of Infection in Clinical Laboratory and Preventive Measures / 中华医院感染学杂志

OBJECTIVE To prevent occurrence of infection in clinical laboratory. METHODS The biosafety system was continuously improved and complet step by step and amplifed rules and regulation,done well protection of person,making the operating process of laboratory more norma,enforcing the air and environment,sterilizeing the equipment,detecting implement,disinfecting the used material and medical garbage and inspecting. RESULTS The hospital infection in laboratory was effectly controlled,the staff′s safety and health were addressd when they worked in an infected area of laboratory. CONCLUSIONS Amplifying the rules and regulation,and insisting the principle of work without slacking could effecttively prevent the occurring of hospital infection in clinical laboratory.
