Background With the events reporting on odors in drinking water, odorous substances in water have become a hot topic in water quality analysis. Due to the low concentration of the odor threshold and the complexity of the odor components in water, it is difficult to make accurate qualitative and quantitative analysis. So it is necessary to develop a highly sensitive and accurate qualitative and quantitative analysis method. Objective To establish a method for simultaneous determination of four odorous substances, including dimethyl disulfide, dimethyl trisulfide, 2-methylisoborneol, and geosmin in water by purge and trap-gas chromatography-tandem mass spectrometry. Methods A certain amount of water sample was stored in the sample vial of a purge and trapinstrument. Through nitrogen purging, the odorous substances in water were purged out and enriched in the trap. Subsequently, the odorous substances were rapidly released at high temperatures after heating the trap, and then carried by carrier gas into gas chromatograph. After temperature programming, the substances were separated by an Agilent DB-624 capillary chromatographic column (30 m×0.25 mm, 1.4 μm) and determined by tandem mass spectrometry in multiple reaction monitoring modes, with internal standard method for quantification. The current project optimized purge time, sodium chloride concentration in water sample, desorption temperature, desorption time, and split ratio during the experimental process. Under the optimized experimental conditions, the standard curve, detection limit, and quantification limit were validated. Recovery tests with spiking concentrations of 5.0, 10.0, 30.0, 80.0 ng·L⁻¹ and precision tests were conducted on water samples. Finally, the established method was applied to detect odorous substances in source water, finished water, and pipeline water in Deqing County of Huzhou City. Result After the optimization, the purge time was 20 min, the desorption temperature was 280 ℃, the desorption time was 2 min, the split ratio was 10∶1, and no sodium chloride was added during the purge process. Under the optimized experimental conditions, the calibration curves for the four odorous substances showed an excellent linearity in the range of 1 to 100 ng·L⁻¹ (R>0.999), with 0.3 ng·L⁻¹ limit of detection and 1.0 ng·L⁻¹ limit of quantitation. The average recoveries were from 85.5% to 102.4% and relative standard deviations (RSD) from 1.6% to 5.2%. After applying this method to detect local source water, finished water, and pipeline water, it was found that the positive rates of 2-methylisoborneo, and geosmin were relatively high, while the positive rates of dimethyl disulfide and dimethyl trisulfide were relatively low. Only one sample of source water tested positive for dimethyl disulfide, and all samples were negative for dimethyl trisulfide. Conclusion Combined with the superiority of purge and trap and tandem mass spectrometry, the method has the advantages of easy to perform, strong anti-interference ability, good accuracy and precision, which meet the limit requirements of the four odorous substances in the expanded indices and reference indices of Hygienic standards for drinking water (GB 5749-2022). It also provides technical support for water quality assessment and analysis of odorous substances.

Background::Familial hypercholesterolemia (FH) is underrecognized, and its association with coronary artery disease (CAD) remains limited, especially in China. We aimed to investigate the prevalence of FH and its relationship with CAD in a large Chinese cohort.Methods::FH was defined using the Make Early Diagnosis to Prevent Early Death (MEDPED) criteria. The crude and age-sex standardized prevalence of FH were calculated based on surveys of the Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR) project during 2007-2008. The associations of FH with incident CAD and its major subtypes were estimated with the cohort-stratified multivariate Cox proportional hazard models based on the data from the baseline to the last follow-up (2018-2020).Results::Among 98,885 included participants, 190 participants were defined as FH. Crude and age-sex standardized prevalence and 95% confidence interval (CI) of FH were 0.19% (0.17%–0.22%) and 0.13% (0.10%–0.16%), respectively. The prevalence varied across age groups and peaked in the group of 60–<70 years (0.28%), and the peak prevalence (0.18%) in males was earlier, yet lower than the peak crude prevalence in females (0.41%). During a mean follow-up of 10.7 years, 2493 cases of incident CAD were identified. After multivariate adjustment, FH patients had a 2.03-fold greater risk of developing CAD compared to non-FH participants.Conclusions::The prevalence of FH was estimated to be 0.19% in the participants, and it was associated with an elevated risk of incident CAD. Our study suggests that early screening of FH has certain public health significance for the prevention of CAD.

Objective:To investigate the evaluation value of one-stop whole-brain dynamic volume CT angiography and CT perfusion imaging (CTA-CTP) in the cynomolgus monkeys models of middle cerebral artery occlusion (MCAO).Methods:Ten adult cynomolgus monkeys were selected and examined by head and neck CTA-CTP and craniocerebral MRI to rule out craniocerebral space-occupying lesions or cerebrovascular malformation. Under guidance of digital substraction angiography (DSA), the right femoral artery was dissected and monkey autologous thrombosis was injected into the right middle cerebral artery (MCA) through microcatheter to prepare MCAO models. Whole brain DSA was performed intraoperatively to observe whether the model was successfully prepared, and head and neck CTA-CTP was performed 24 h and 7 d after modeling to determine the locations and brain blood flow changes of ischemic lesions. The monkeys were sacrificed 8 d after modeling, and the brain tissues were stained with 2,3,5-triphenyltetrazolium chloride (TTC).Results:Among the 10 cynomolgus monkeys, one was excluded because of preoperative cerebrovascular malformation, and one died of cerebral hernia caused by cerebral hemorrhage during the experiment. The remaining 8 MCAO models were successfully prepared. Intraoperative DSA orthography showed unclear M1 segment and distal branch of MCA. Brain CT scan 24 h and 7 d after modeling showed obvious cerebral ischemic lesions in the right MCA blood supply area, and the infarct extent 7 d after surgery was more obvious than that 24 h after surgery. CTA examination showed obvious blood flow interruption imaging in the in M1 segment of MCA on the right side, the distal vessels were not clearly displayed and the distal branches of the infarct side 7 d after surgery were obvious decreased as compared with those 24 h after surgery. CTP scan showed that the cerebral blood volume of the right cerebrum was obviously reduced as compared with that of the left cerebrum, which was consistent with the blood supply area of MCA; and the infarct cores and penumbra areas 7 d after surgery were obvious increased as compared with those 24 h after surgery. TTC staining showed that the ischemic lesions of the brain tissue on the slices were gray and involved multiple layers, and the range was roughly consistent with the infarction sites shown by DSA and CT imaging.Conclusion:One-stop whole brain dynamic volume CTA-CTP has good evaluation value in imaging findings in MCAO animal models.
