To develop and validate a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the quantification of epirubicin hydrochloride (EPI) in rat plasma, daunorubicin hydrochloride was used as internal standard. The plasma samples were deproteinated with methanol, and separation was performed on a reversed-phase CAPCELL PAK C18 column (3.0 mm x 50 mm, 3 microm). The mobile phase contained methanol-0.1% formic acid (80:20). Detection was carried out by multiple reaction monitoring on a HP1200-6410 QQQ LC/MS system. Different preparations of EPI solution, EPI-LIP (EPI-liposome) and EPI-LTSL (EPI-thermosensitive liposome) was administered in rats by i.v with the same dosage (12 mg kg(-1)). The pharmacokinetic model and parameters were fitted and calculated by the DAS ver2.0 software. The calibration curve was linear in the range of 0.01-50 microg mL(-1). The limit of quantification was 0.01 microg mL(-1). RSDs of intra- and interbatch precisions were all less than 11.9%. The average extract recovery was 89.3% and 92.1%, respectively. The pharmacokinetics of EPI in rats with all preparations were fitted to three compartments, which all fast distributed and slowly eliminated. The t1/2 alpha, t1/2 beta, t1/2 gamma, AUC(0-infinity), and MRT(0-infinity) of EPI-LTSL group were 7.5, 1.3, 12.6, 12.9, 3.7 times those of EPI solution group; and 1.6, 1.4, 12.3, 2.9, 2.6 times those of EPI-LIP group. Moreover, the CL of the latter two groups was about 13.4 times of the former EPI-LTSL group. EPI-LTSL can significantly improve AUC and prolong the circulation time of EPI in rat plasma.

Associations between "lipid-related" candidate genes, blood lipid concentrations and coronary artery disease (CHD) risk are not clear. We aimed to investigate the effect of three newly identified lipids loci from genome-wide association studies on CHD and blood lipid levels in Chinese Han population. The genotypes of SNPs at three newly identified lipid loci and blood lipids concentrations were examined in 1360 CHD patients and 1360 age- and sex-frequency matched controls from an unrelated Chinese Han population. Allele T of rs16996148 occurred less frequently in CHD patients with the odds ratio (OR) being 0.64 (95% CI 0.50 to 0.81), after adjusting for conventional risk factors and was associated with a 33% decreased CHD risk (P<0.01) comparing with the major allele G. Individuals with GT genotype had the lowest CHD risk. No associations were found between the polymorphisms of other two loci with CHD risk and all three SNPs had no effect on lipid profile in this population. SNP rs16996148 on chromosome 19p13 is significantly associated with lower risk for CHD in Chinese Han population. However, it remains unresolved why these lipid-related loci had significantly less effects than the correspondingly expected effects on blood lipids levels in this population.

Objective To assess the factors that influence the accuracy of real-time continuous glucose monitoring system (RT-CGM).Methods A total of 79 diabetic patients wore RT-CGM for three days continuously while calibrating by interphalangeal glucose values 4-8 times a day.We counted matching rate of interphalangeal glucose values and RT-CGM probe value,and analyzed correlation of the matching rate with MAGE,SDBG,MBG,AUC10,AUC3.9,and NGE by Pearson correlation analysis and multiple linear regression analysis.Then we grouped corresponding match rate by MAGE and MBG,compared the difference among groups.Furthermore,we analyzed correlation of RT-CGM probe values of all-day,fasting-postprandial,and nighttime and the corresponding interphalangeal glucose values by Pearson correlation analysis.Results Pearson correlation analysis showed that the matching rate was negatively correlated with the MAGE,SDBG,MBG,and AUC10.MAGE,MBG,and NGE were in the regression equation.MAGE <3.9 mmol/L,matching rate was 81%,3.9 ≤ MAGE<7 mmol/L,matching rate was 67%,MAGE≥7 mmol/L,the matching rate was 52%,the difference among 3 groups was statistically significant (P<0.01).MBG<7.8 mmol/L,matching rate was 78%,7.8 ≤ MBG< 10 mmol/L,matching rate was 68%,MBG ≥10 mmol/L,the matching rate was 57%,the difference among 3 groups was statistically significant (P < 0.01).When Youden index was 0.409 and MAGE was less than 3.745 mmol/L,the match rate was more than 75%.When Youden index was 0.369 and MBG was less than 8.38 mmol/L,the matching rate was more than 75%.The correlation coefficients of all day,fasting,postprandial and nighttime probe values and the corresponding interphalangeal glucose values were 0.958,0.963,0.944,and 0.965 (all P<0.01).Conclusions The probe values show good consistency with the interphalangeal glucose values,are able to be used for blood glucose assessment.Blood glucose fluctuations influences accuracy of RT-CGM,the smaller the blood glucose fluctuations,the smaller the mean glucose concentration,the smaller the effective blood glucose fluctuations in frequency,the higher would be the accuracy.It seems to be more effective to do calibration during fasting and nighttime.
