Objective:To develop a candidate reference method for cortisol in human serum by isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC/MS/MS).Methods:An isotope-labeled internal standard was added to samples, followed by alkalizing with sodium carbonate solution and liquid-liquid extraction with n-hexane/ethyl acetate. Isoelution with a methanol aqueous solution was employed for liquid chromatographic separation, while ESI in the positive ion and multiple reaction monitoring mode were used for mass spectrometry. The volume of sample, standard, and internal standard solutions were all controlled by weighing, and the results were calculated by bracketing method. The accuracy, precision, specificity, linearity, LOD and LOQ of this method were evaluated referring to the CLSI C62-A and C50-A guidelines and the domestic expert consensus documents.Results:The method demonstrated excellent accuracy and precision with the bias of ERM-DA192, ERM-DA193 and RELA 2021-2023 all being less than 2%. The recovery of added cortisol ranged from 98.2% to 101.1%. Both intra- and inter-assay imprecisions was <2%. The method was free from interference by structural analogue and showed a good linearity in the range of 25-1 600 nmol/L. The LOD and LOQ were 0.5 nmol/L and 1.0 nmol/L, respectively. A cortisol assay kit (chemiluminescence immunoassay) traced to this candidate reference method was used to determine 46 clinical serum samples concurrently, and the two methods exhibited good correlation.Conclusions:A candidate reference method for the determination of cortisol in serum was established, demonstrating high sensitivity, good repeatability and accuracy. This method can serve as a reference for the measurement traceability and accuracy evaluation of routine methods.

OBJECTIVES: Patients with classical type 1 diabetes mellitus (T1DM) require lifelong dependence on exogenous insulin therapy due to pancreatic beta-cell destruction and absolute insulin deficiency. T1DM accounts for about 90% of children with diabetes in China, with a rapid increase in incidence and a younger-age trend. Epidemiological studies have shown that the overall glycated haemoglobin (HbA1c) and compliance rate are low in Chinese children with T1DM. Optimal glucose control is the key for diabetes treatment, and maintaining blood glucose within the target range can prevent or delay chronic vascular complications in patients with T1DM. Therefore, this study aims to investigate the glycemic control of children with T1DM from Hunan and Henan Province with flash glucose monitoring system (FGMS), and to explore factors associated with glycemic variability. METHODS: A total of 215 children with T1DM under 14 years old were enrolled continuously in 16 hospitals from August 2017 to August 2020. All subjects wore a FGMS device to collect glucose data. Correlation of HbA1c, duration of diabetes, or glucose scan rates with glycemic variability was analyzed. Glucose variability was compared according to the duration of diabetes, HbA1c, glucose scan rates and insulin schema. RESULTS: HbA1c and duration of diabetes were positively correlated with mean blood glucose, standard deviation of glucose, mean amplitude of glucose excursions (MAGE), and coefficient of variation (CV) of glucose (all P<0.01). The glucose scan rates during FGMS wearing was significantly positively correlated with time in range (TIR) (P=0.001) and negatively correlated with MAGE and mean duration of hypoglycemia (all P<0.01). Children with duration ≤1 year had lower time below range (TBR) and MAGE when compared with those with duration >1 year (all P<0.05). TIR and TBR in patients with HbA1c ≤7.5% were higher (TIR: 65% vs 45%, TBR: 5% vs 4%, P<0.05), MAGE was lower (7.0 mmol/L vs 9.4 mmol/L, P<0.001) than those in HbA1c >7.5% group. Compared to the multiple daily insulin injections group, TIR was higher (60% vs 52%, P=0.006), MAGE was lower (P=0.006) in the continuous subcutaneous insulin infusion group. HbA1c was lower in the high scan rates (≥14 times/d) group (7.4% vs 8.0%, P=0.046), TIR was significantly higher (58% vs 47%, P<0.001), and MAGE was lower (P<0.001) than those in the low scan rate (<14 times/d) group. CONCLUSIONS The overall glycemic control of T1DM patients under 14 years old in Hunan and Henan Province is under a high risk of hypoglycemia and great glycemic variability. Shorter duration of diabetes, targeted HbA1c, higher glucose scan rates, and CSII are associated with less glycemic variability.

【Objective】 To evaluate the associations of total fat and fatty acid consumption with the risk of hypertension among rural residents in Hanzhong, Shaanxi Province. 【Methods】 A cross-sectional survey on dietary status with a semi-quantitative food frequency questionnaire was conducted among rural residents aged between 18 and 80 years old in Hanzhong of Shaanxi. Multivariate log-binomial regression models and restricted cubic spline were used to explore the associations of dietary total fat, saturated fatty acid, polyunsaturated fatty acid and monounsaturated fatty acids with hypertension and as well as association between dose and response. 【Results】 A total of 2241 individuals were included, with 774 males and 1467 females. Monounsaturated fatty acid accounted for 51.9% of total dietary fat intake, while the other two fatty acids for 48.1%. The intake of dietary fat and any fatty acid in men was significantly in men higher than in women (P<0.001). Results of multivariable log-binomial regression indicated that after adjustment of energy, socio-demographic and lifestyles, the risk of hypertension reduced significantly in Q4 group, compared with that in Q1 (PR: 0.71, 95% CI: 0.54-0.92; P-trend: 0.022) in females. A nonlinear dose-response relationship between monounsaturated fatty acids and hypertension was detected by restricted cubic spline in women (Pnon-linear<0.01). No association was observed of total fat, saturated fatty acid and polyunsaturated fatty acid with hypertension regardless of the gender. 【Conclusion】 In women, increased consumption of monounsaturated fats might play a positive role in reducing the risk of hypertension. Further research is warranted to verify the rationality of causal inference and break-point.
