Combination of duplex PCR technology with capillary electrophoresis is an alterna-tive method to validate the result of transcriptome sequencing / 军事医学

Objective To establish a method to validate the result of transcriptome sequencing using duplex PCR tech -nology combined with capillary electrophoresis .Methods According to a previous study on transcriptome sequencing , eight differentially expressed genes were chosen as target genes for examination .The mRNA expression level of these genes was detected using duplex PCR combined with agarose gel electrophoresis , duplex PCR combined with capillary electropho-resis and Q-PCR, respectively.Then, the verification efficiency of each method was evaluated carefully .Results The ver-ification efficiency of duplex PCR combined with agarose gel electrophoresis was 50%, while that of duplex PCR combined with capillary electrophoresis and Q-PCR was both 100%.Conclusion Combination of duplex PCR technology with capil-lary electrophoresis can be used as an alternative method to validate the results of transcriptome sequencing .

The relationship between the extent and severity of angiographic coronary artery disease and impaired fasting glucose / 中国医师杂志

Objective To evaluate the correlation between impaired fasting glucose and the extent and severity of angiographic coronary artery disease( CAD ) in patients who underwent coronary angiography.Methods A total of 630 consecutivc patients who underwent coronary angiography were selected in the stndy.The extent and severity of angiographic CAD were diagnosed based on the followings:whether or not with CAD diagnosis by angiography,the number of diseased vessels,the CAD Gensini cumulative index.According to fasting plasma glucose ( FPG),all patients were divided into three group,group 1 ( FPG ＜5.6 mmol/L),group 2 ( 5.6 mmol/L ≤ FPC ＜ 6.1 mmol/L) and group 3 ( 6.1 mmol/L ≤ FPG ＜ 7.0mmol/L).The CHD risk factors and the lesion degree of coronary arteries were compared among three groups.The relation of FPG and CAD were analyzed by univariate and multivariate analyses.Results The incidence of CH and,the CAD Gensini cumulative index and the incidence of mult-vessel lesions were significantly different among the three subgroups ( all P ＜ 0.05 ).After adjusting other inffluencing factors,there were significantly positive correlation between the number of diseased vessels and the CAD Gensini cumulative index and FPG( P ＜0.05).The FPG had significant correlation with the diagnosis or not of CAD by angiography( OR =3.042,95％ CI:2.589 -6.275,P ＜0.01).Conclusions In prediabetic period,the extent and severity of angiographic coronary artery disease have significant correlations with the impaired fasting glucose,and the extent and severity can increase along with the increasing FPG.
