[Objective] To investigate the therapeutic effect of Shugan Jianpi Decoction , a formula mainly composed of Radix Bupleuri, Pericarpium Citri Reticulatae, Radix Codonopsis, Radix Astragali, Placenta Hominis, etc., in treating iron-deficiency anemia and to explore its mechanism. [Methods] One hundred and seventy-one cases of iron-deficiency anemia were randomized to two groups: group A was treated with Shugan Jianpi Decoction and group B with ferrous sulfate for 4 weeks. Symptoms and signs of anemia were observed and levels of hemoglobin (Hb), red blood cells (RBC), mean corpuscular hemoglobin (MCH) and serum ferrin (SF) were detected before and after treatment to evaluate the effects of the two drugs. [Results] The symptoms and signs of anemia were improved and levels of Hb, RBC, MCH and SF were increased after treatment in the two groups ( P

Objective:To explore the clinical characteristics and distribution of Tranditional Chinese Medicine (TCM) syndrome types of refractory tic disorders in children based on clustering analysis.Methods:A cross-sectional study. 183 children aged 3-18 years with refractory tic disorders from pediatric encephalopathy outpatient department of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine who met the inclusion criteria from October 2015 to January 2022 were recruited. Frequency descriptive analysis, systematic clustering analysis and principal component analysis were conducted by Microsoft Office Excel 2016 and IBM SPSS Statistics 26.0 to explore the clinical characteristics and syndrome distribution of the disease.Results:The TCM symptoms of 183 children with refractory tic disorders were clustered into 6 categories, and finally 5 types of syndrome were obtained, among which the syndrome of spleen deficiency and liver hyperactivity mixed with dampness accounted for the largest proportion (27.32%), followed by the syndrome of phlegm-fire disturbing spirit (21.31%), the syndrome of wind-heat invading lung (18.03%), the syndrome of phlegm-qi stagnation (17.49%), and the syndrome of dampness and yin deficiency (15.85%).Conclusion:Through the mining and analysis of the outpatient information of pediatric encephalopathy in our hospital, the common syndrome differentiation types of refractory tic disorder are obtained, which can provide a reference for the TCM syndrome differentiation types of refractory tic disorder in children.

Objective Accurate measurement of aldosterone is critical in the diagnosis of primary aldosteronism. We compared the harmonization of three assays including isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) and two chemiluminescence immunoassays (CLIAs:system A and system B) for the aldosterone measurement. Methods A total of 45 plasma samples, 4 quality control materials, 5 lyophilized bovine serums, and 3 fresh frozen human serum pools were measured by three assays respectively. Based on CLSI EP15-A3 rule, the precision was assessed by coefficient of variance. Deming regression and Bland&Altman plots was performed for method comparison, and correlation coefficient was calculated for concordance (CCC). Results All three methods met the performance criteria based on desirable biological variation for precision (<7.35％). System A showed a relevantly good correlation and comparability with ID-LC/MS/MS (R2=0.985, CCC=0.967), while System B showed relevantly bad correlations and comparability with both System A (R2=0.538, CCC=0.605) and ID-LC/MS/MS (R2=0.547, CCC=0.528).. However, the average relevant bias of two CLIAs exceeded the bias requirement derived from biological variation (18.60％). Conclusion Significant differences were found in the measurement of plasma aldosterone using ID-LC-MS/MS and two CLIAs, which urges the establishment of traceability hierarchy and improvement of reagents' specificity for standardization of aldosterone measurement in clinical settings.
