ABSTRACT

Objective:To investigate the correlation between the prolongation of the QTc interval and carotid atherosclerosis in elderly patients with type 2 diabetes mellitus(T2DM).Methods:CIinical data of 212 elderly patients with T2DM admitted to our hospital from February 2016 to February 2019 were retrospectively collected.Based on carotid intima-media thickness(CIMT), patients were divided into the CIMT≥1.0 mm group(n=110)and the CIMT<1.0 mm group (n=102). Meanwhile, patients were divided into the prolonged QTc interval group(QTc interval>440 ms, n=50)and the normal QTc interval group(QTc interval≤440 ms, n=162), base on the adjusted QTc interval.General clinical data were compared between the groups, and the logistic regression equation was used to analyze the related factors for carotid atherosclerosis.Results:Higher values of age, duration of disease, systolic blood pressure(SBP), fasting plasma glucose(FPG), triglycerides(TG), creatinine(Cr), uric acid and C-reactive protein(CRP)were found in the CIMT≥1.0 mm group than in the CIMT<1.0 mm group( P<0.05). The QTc interval was longer in the CIMT≥1.0 mm group than in the CIMT<1.0 mm group[(419.2 ± 42.6) ms vs. (396.5 ± 45.2) ms, t=3.849, P<0.01]. CIMT was greater in the prolonged QTc interval group than in the normal QTc interval group[(1.2± 0.3)mm vs.(0.9±0.3) mm, t=6.956, P<0.01]. The detection rates of carotid atherosclerosis, intimal thickening and atheromatous plaques were higher in the prolonged QTc interval group than in the normal QTc interval group( 76.0% or 38 vs. 44.4% or 72, 32.0% or 16 vs.18.5% or 30 and 44.0% or 22 vs.25.9% or 42, respectively, χ2=15.239, 4.087 and 5.922, P<0.05). Pearson’s correlation analysis showed that CIMI was positively correlated with age, duration of disease, SBP, FPG, TG, Cr, uric acid, CRP and QTc interval( P<0.05). Multivariate logistic regression showed that the risk of carotid atherosclerosis in patients with QTc interval>440 ms was 1.761 times higher than that in patients with QTc≤440 ms( OR=1.761, 95% CI: 1.460-3.126, P<0.01). Conclusions:QTc interval prolongation is correlated with carotid atherosclerosis in elderly patients with T2DM, and attention should be paid to the QTc interval on the electrocardiogram, which is helpful to assess the risk of carotid atherosclerosis in elderly T2DM patients.

ABSTRACT

Objective To evaluate the value of PET-CT in patients with breast cancer and to determine if the PET-CT can provide additional information to predict early response to neoadjuvant chemotherapy (NAC).Methods NAC was given to 20 patients with breast cancer confirmed by biopsy puncture from September 2009 to March 2012.The PET-CT was carried out for all patients before NAC.TEC program with three weeks for one cycle was selected.After 6 days of the first cycle,the PET-CT was performed again.The changes of standard uptake value before and after the first cycle were compared.At the same time hand palpation was selected to detect the changes in tumor size before and after the first cycle of NAC.The changes of the standard uptake value and in tumor size need to refer to the pathology Miller & Payne classification methods to evaluate the efficacy of the NAC.Results The SUV were (7.51±1.76) Bq/ml and (4.98±1.61) Bq/ml before and after chemotherapy (t =7.916,P < 0.05) the maximum tumor diameters were (9.62±4.38) cm and (8.89±4.08) cm before and after NAC (t =2.154,P> 0.05).SUV had highly correlated with pathological MP classification (r =0.725,P =0.000); while for the tumor size there was no significant change (r =0.026,P =0.824).Conclusion PET-CT can predict the efficacy earlier and is more accurate than clinical efficacy standard for the NAC.
