Objective:To explore the relationship between coronary artery measurements combined with C-reactive protein(CRP), erythrocyte sedimentation rate(ESR) and coronary artery lesionsin(CAL) with incomplete Kawasaki disease (IKD) in children.Methods:Sixty-eight cases of pediatric IKD admitted to Huaibei Maternal and Child Health Care Hospital from January 2020 to April 2024 were selected as the IKD group, and 34 healthy children undergoing physical examination during the same period were selected as the control group according to the principle of 2∶1 pairing. Echocardiographic Z values including left coronary artery (LCA)-Z, right coronary artery (RCA)-Z, left anterior descending branch (LAD)-Z, left circumflex branch (LCX)-Z and CRP, ESR were compared between the two groups. General information of children with or without CAL were compared. The multivariate Logistic regression was used to screen the risk factors of IKD combined with CAL, and receiver operating characteristic (ROC) curve was used to analyze the predictive value of each index to IKD combined with CAL.Results:The LCA-Z, RCA-Z, LAD-Z, LCX-Z and the levels of CRP, ESR in the IKD group were higher than those in the control group: 3.26 ± 0.97 vs. 1.35 ± 0.28, 3.46 ± 0.92 vs. 1.01 ± 0.29, 3.18 ± 0.69 vs. 1.18 ± 0.34, 2.97 ± 0.68 vs.1.27 ± 0.34, (39.97 ± 9.03) mg/L vs. (4.21 ± 1.05) mg/L, (59.67 ± 16.34) mm/1 h vs. (12.85 ± 2.43) mm/1 h, there were statistical differences ( P<0.05). The duration of fever, intravenous immunoglobulin (IVIG) treatment response, IVIG start time, creatine kinase (CK), creatine kinase-MB(CK-MB), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) between the children with IKD and CAL, IKD without CAL: (10.02 ± 2.45) d vs. (7.68 ± 1.43) d, 65.22%(15/23) vs. 88.89%(40/45), 60.87%(14/23) vs. 86.67%(39/45), (236.78 ± 59.74) U/L vs. (192.67 ± 35.41) U/L, (45.19 ± 9.85) U/L vs. (33.18 ± 9.87) U/L, (1.78 ± 0.32) μg/L vs. (0.92 ± 0.20) μg/L, there were statistical differences ( P<0.05). Logistic regression analysis showed that the duration of fever, IVIG treatment response, IVIG initiation time, CK, CK-MB, NT-proBNP, echocardiographic Z value, CRP and ESR levels were independent risk factors for IKD combined with CAL ( P<0.05). ROC curve analysis results showed that the area under the curve of IKD combined with CAL predicted by LCA-Z, RCA-Z, LADE-Z, LCX-Z, CRP and ESR was the largest, which was 0.917 (95% CI 0.824 - 0.970), which was higher than that diagnosed by each index alone ( P<0.05). Conclusions:There is a certain relationship between the echocardiographic Z values, CRP and ESR in children with IKD and CAL, which can be used to assist in the evaluation of IKD complicated with CAL.

Objective To compare the effects of ticagrelor and clopidogrel on platelet aggregation rate, myocardial perfusion and prognosis in patients with acute myocardial infarction. Methods One hundred and sixty-nine patients with acute ST segment elevation myocardial infarction (STEMI) and emergency percutaneous coronary intervention (PCI) were recruited and randomly divided into ticagrelor group (85 cases) and clopidogrel group (84 cases). The TIMI blood flow before and after PCI was recorded, and the ST segment fall rate of 1 h ECG after PCI was calculated. The platelet aggregation rate was measured. After 12 months' follow-up, the incidence of major adverse cardiac events (MACE) was recorded. The Logistic regression analysis was used to discover the factors of MACE. Results One hundred and sixty-nine patients with acute STEMI were recruited including 85 cases treated with ticagrelor and 84 cases in clopidogrel group. The ECG ST segment fall rate after PCI in ticagrelor group was significantly higher than that in clopidogrel group: (61.3 ± 30.7)％ vs. (47.8 ± 26.6)％, P<0.05. The platelet aggregation rate 2 h, 24 h and 7 d after PCI in ticagrelor group was significantly lower than that in clopidogrel group (P<0.05). MACE occurred in 19 cases (22.4％) in ticagrelor group and in 21 cases (25.0％) in clopidogrel group, and there was no significant difference (P > 0.05). Multiple Logistic regression analysis revealed that age and ECG ST segment fall rate were independent risk factors for MACE (P<0.05). Conclusions Compared with clopidogrel, ticagrelor can effectively reduce platelet aggregation rate and accelerate ST segment fall in STEMI patients, but their long-term prognosis is similar.

OBJECTIVE: To investigate the effect of vitamin D3 on polarization of monocyte macrophages induced by serum from patients with ankylosing spondylitis (AS). METHODS: Twenty AS naïve patients and 20 healthy controls from Wenzhou People's Hospital during January 2016 and December 2017 were enrolled. The macrophages were differentiated from THP1 cells induced by phorbol 12-myristate 13-acetate (PMA), and then co-cultured with the serum from healthy subjects (control group) or AS patients. Vitamin D3 was added in the medium mixed with serum from AS patients. Flow cytometry was used to analyze the ratio of CD68 and CD206 positive cells, and RT-PCR was performed to detect the mRNA expression of inducible nitric oxide synthase(iNOS) and arginase-1(Arg-1). RESULTS: THP1 cells could be polarized into mononuclear-macrophages with the induction of PMA. The proportion of CD206 positive cells in AS-serum group was lower than that in the control group (=9.434, <0.05), while the proportion of CD68 positive cells was higher than that in the control group (=43.920, <0.05). The proportion of CD206 positive cells in vitamin D3 group was higher than that in AS-serum group (=8.895, <0.05), while the proportion of CD68 positive cells was lower than that in AS-serum group (=9.089, <0.05). mRNA expression of Arg-1 in AS-serum group was lower than that in the control group (=8.899, <0.05), while mRNA expression of iNOS was higher than that in the control group (=3.656, <0.05). mRNA expression of Arg-1 in vitamin D3 group was higher than that in AS-serum group (=6.219, <0.05), while mRNA expression of iNOS was lower than that in AS-serum group (=5.876, <0.05). CONCLUSIONS Vitamin D3 can regulate the polarization of mononuclear macrophages for immunoregulation in patients with AS.

Objective To investigate the distribution and changing resistance proifle ofSalmonella isolates in hospitals across China during the period from January 2005 to December 2014.Methods Seventeen general hospitals and two children’s hospitals were involved in this program. Antimicrobial susceptibility testing was carried out by means of a unified protocol using Kirby-Bauer method or MIC determination. The results were analyzed according to CLSI 2014 breakpoints.Results The proportion ofSalmonella isolates increased with time from 0.2% in 2005 to 0.7% in 2014. A total of 3 478Salmonella strains were collected from 19 hospitals. The proportion ofSalmonella typhimurium andSalmonella enteritidis was 27.4% and 24.4%, respectively. During the 10-year period, theSalmonella strains showed highest resistance rate to ampicillin (33.3%-64.8%), but low resistance to cefoperazone-sulbactam (0-5.3%) and ciprofloxacin (2.4%-14.3%).S. typhimurium showed higher resistance rate thanS. typhi,S. paratyphi andS. enteritidis. About 76.8% and 50.5% ofS. typhimurium were resistant to ampicillin and trimethoprim-sulfamethoxazole. The average prevalence of multi-drug resistantSalmonellawas 3.9% in the ten-year period, the highest (7.5%) was in 2005, the lowest (1.5%) in 2013.Conclusions During the period from 2004 to 2015, majority of theSalmonella isolates in hospitals across China wasS. typhimurium andS. enteritidis. Ampicillin and trimethoprim-sulfamethoxazole are no longer appropriate for empirical treatment ofS. typhimurium infection due to high resistance rate.Salmonella isolates are relatively more susceptible to third-generation cephalosporins and quinolones. Ongoing monitoring is necessary to identify multi-drug resistant strains ofSalmonella.
