Objective:To establish a pure water direct dilution-inductively coupled plasma mass spectrometry (ICP-MS) detection method for rapid determination of urinary iodine.Methods:Pure water was used to directly dilute the urine samples. The washing solution was 5.0 g/L ascorbic acid, the internal standard solution was 5.0 g/L ascorbic acid and 100 μg/L 128Te, the standard solution was prepared with the solution of lyophilized urine iodine biological component analysis reference material. The method was evaluated in terms of linear range, detection limit, quantification limit, precision and method comparision experiment. Results:The linear correlation coefficient of the standard curve for iodine concentration range from 0 to 50.0 μg/L was 0.999 7, with a detection limit of 0.2 μg/L and a quantification limit of 0.6 μg/L. The spiked recovery rates of low, medium, and high concentration iodine standard solutions added to actual urine samples were 100.8%, 99.1% and 99.7%, respectively, with relative standard deviations of 0.8%, 1.3% and 1.6%, respectively. There was no statistically significant difference ( t = - 0.14, P = 0.890) between the results of measuring actual urine and assessment urine using this method and "Determination of Iodine in Urine-Part 2: Inductively Coupled Plasma Mass Spectrometry (WS/T 107.2-2016)". Conclusions:We have successfully established a pure water direct dilution-ICP-MS method for determining urinary iodine. This method provides accurate and highly sensitive results, making it suitable for sudden public health emergencies and large-scale clinical measurement of urinary iodine.

Ankylosing spondylitis is a chronic immunoinflammatory disease that mainly affects the spine and the sacroiliac joint,the mechanism of which is closely related to signaling pathways,such as osteoprotegerin(OPG)/receptor activator of nuclear factor-κB(RANK)/RANK ligand,mitogen-activated protein kinase(MAPK),Wnt/β-catenin(β-catenin),phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR).Traditional Chinese medicine has the characteristics of multiple components and targets,and is widely used for the treatment of autoimmune diseases due to its low toxicity,strong specificity,and high efficacy.This review found that monomers and compounds of traditional Chinese medicine can exert anti ankylosing spondylitis effects by intervening in the aforementioned signaling pathways,regulating immune inflammatory responses,and inhibiting biological processes such as bone destruction,ectopic osteogenic differentiation,cell apoptosis,and autophagy.

Objective:To compare the predictive ability of SpO 2/FiO 2(S/F) and ROX index on the failure of high-flow nasal cannula(HFNC)therapy in children with acute respiratory failure after congenital heart disease surgery, and to identify the best cut-off point. Methods:Through a case-control study, the clinical data of 371 children with acute respiratory failure after congenital heart surgery treated with HFNC admitted to Guangzhou Women and Children′s Medical Center from January 2018 to December 2021 were retrospectively analyzed.The primary outcome was the need for re-intubation within 48 h after extubation of invasive ventilation.The ability of S/F and ROX index to predict HFNC failure was compared, and the optimal cut-off point was determined based on the area under the curve (AUC) of receiver operating characteristic curve.Results:A total of 371 children were included, of whom 27 (7.3%) eventually required mechanical ventilation within 48 h. The S/F prediction accuracy was highest after 6 h of HFNC treatment(AUC=0.712, 95% CI 0.599-0.825, P=0.001), and the best cut-off point for S/F was 178 mmHg(1 mmHg=0.133 kPa)(sensitivity 74.9%, specificity 69.6%). Whereas the prediction accuracy of the ROX index was highest after 12 hours of HFNC treatment, the AUC was 0.737(95% CI 0.623-0.851, P=0.002), and the best cut-off point of the ROX index was 5.865(sensitivity 72.4% specificity 66.7%). The difference in AUC between S/F after 6 h of HFNC treatment and ROX after 12 h was not statistically significant ( P=0.444), with higher sensitivity and specificity, and earlier prediction time(6 hours) in the former. Conclusion:Children with acute respiratory failure after congenital heart surgery have a strong predictive ability of S/F after 6 h of HFNC treatment, and the risk of HFNC treatment failure is higher in children with S/F <178 mmHg.

Objective:To explore the normal ranges of perfusion parameters between cerebral hemisphere, cerebellar hemisphere and brain anatomical subregions (56 pairs) in different gender and age groups with multiple post labeling delay time (Multi-PLD) arterial spin labeling (ASL) imaging.Methods:From November 2020 to December 2020, 42 healthy adult volunteers (Male 25, Female 17) were recruited to perform 7 PLD ASL imaging, including 21 young adults (15 males and 6 females, aged 23—35 years) and 21 seniors (10 males and 11 females, aged 36—74 years). The data was processed offline by Cereflow software to obtain arterial arrival time (ATT) and corrected cerebral blood flow (CBF) and cerebral blood volume (CBV) perfusion parameters. SimpleITK standardization function was used to standardize the calculated perfusion image according to the anatomical automatic labeling (AAL) template. Therefore, CBF, ATT, CBV perfusion values of brain subregions were obtained. Paired samples t test, Wilcoxon rank sum test, independent samples t test and Mann-Whitney U test were used to compare the differences of perfusion parameters in the cerebral hemisphere, the cerebellar hemisphere, brain subregions depending on side, gender and age. Pearson correlation analysis was used to compare the correlations of perfusion parameters with age. Results:CBF in 62.5% (35/56) subregions and CBV in 44.6% (25/56) subregions were higher in right side than those in left side. ATT in most brain anatomical subregions (16/56) were higher in left side. The CBF [(35.30±8.31) vs. (34.34±7.53) ml·100g -1·min -1, P=0.021], CBV [(0.47±0.11) vs. (0.45±0.09) ml/100g, P<0.001], ATT [(1.30±0.10) vs. (1.24±0.11) s, P<0.001] in left cerebellar hemisphere were higher than that of right side. The CBF (28/56) of cerebral hemisphere, cerebellar hemisphere and brain subregions was higher in females than that in males, while ATT in 83.9% (47/56) subregions was lower than that in males (all P<0.05). CBV in female subjects was higher only in 5 brain regions (superior occipital gyrus, middle occipital gyrus, inferior occipital gyrus, superior parietal gyrus and cerebelum_7b) (all P<0.05). In young subjects, CBF in 44.6% (25/56) subregions and CBV in 33.9% (19/56) subregions were higher than those in the senior group (all P<0.05). The ATT in most subregions in young group were lower than those in senior group, but the difference was statistically significant only in rectus gyrus ( P=0.026) and paracentral lobule ( P=0.006). The CBF ( r=-0.430, P=0.005) and CBV ( r=-0.327, P=0.035) of cerebral hemisphere were negatively correlated with age. The CBF (24/25, r range:-0.497 —-0.343, all P<0.05) and CBV (16/19, r range:-0.474 —-0.322, all P<0.05) in most subregions were negatively correlated with age, while ATT was positively correlated (gyrus rectus: r=0.311, P=0.045; paracentral lobule: r=0.392, P=0.010). Conclusions:Multi-PLD ASL imaging could be applied for quantitative analysis of brain perfusion. The perfusion parameters of anatomical subregions are different depending on side, gender, and age.

Objective:To explore the influencing factors of all-cause death in patients with acute myocardial infarction (AMI) and renal insufficiency(RI), and establish a clinical prediction tool.Methods:Collected 727 patients who were hospitalized in Beijing Anzhen Hospital from January 1st 2014 to April 31th 2019, and diagnosed as AMI with RI. Recorded the patients' baseline characteristics, past medical history, current complications, laboratory and auxiliary examination results, treatment methods (included target vessel reconstruction methods, medications, etc.), and follow-up patients for all-cause deaths. Firstly, multivariate Cox regression analysis was used to construct the model in the training set(485 cases). Secondly, the receiver operating characteristic curve ( ROC), calibration curve and clinical decision curve analysis (DCA) were drawn in the validation set(242 cases) to further verify the effect of the prediction model. Finally, a nomogram was developed based on the verified risk factors. Results:Multivariate Cox regression analysis found that there were nine predictors for the prognosis of all-cause death in patients with AMI & RI, the dangerous factors included women, comorbidities, high direct bilirubin, cardiogenic shock, respiratory failure, co-infection and hemofiltration; the protective factors included PCI and taking aspirin. Model evaluation results showed that the AUC of the validation set was 0.82; the calibration line was close to the ideal calibration line, and the slope≈1, the intercept≈0, and the fitting effect was good. Clinical decision-making when the all-cause mortality rate was 35%, the net benefit of active intervention patients based on the Cox model was 38%. A visual nomogram model was developed based on the prognostic risk factors that have been evaluated and predicted to be good. Conclusion:Women, with a history of comorbidities, direct high bilirubin, combined with cardiogenic shock, combined with respiratory failure, combined infection, hemofiltration, PCI and taking aspirin, these nine factors will affect all causes of AMI & RI. For the probability of death, the model developed in this research has high accuracy.
