RESUMO
Objective To investigate the relationship between neutrophil/high-density lipoprotein cholesterol ratio(NHR)and the severity of coronary artery lesions in young adults with acute myocardial infarction.Methods A total of 109 young a-dults(aged 18～45 years)with acute myocardial infarction admitted to the First Affiliated Hospital of Anhui Medical University from June 2019 to June 2023 were selected and divided into Syntax low-risk group(n=85)and Syntax medium-high-risk group(n=24)according to Syntax score.Patients with negative coronary angiography during the same period were negative control group(n=52).General clinical data and related serum markers were collected,and NHR value was calculated.Pearson correla-tion analysis and logistics regression analysis were performed to examine the correlation between NHR and the severity of coro-nary artery lesions.Subgroup analysis and interaction testing were further conducted.The receiver operating curve(ROC)was performed to evaluate the value of NHR in predicting the severity of coronary artery lesions in young adults with acute myocar-dial infarction.Results Gender,smoking rate,alcohol consumption rate,diabetes history,absolute number of neutrophils,tri-glyceride,HDL-C,NHR,VLDL-C,apolipoprotein B(APOB),fasting blood glucose and glycosylated hemoglobin were signifi-cantly different among the three groups(P＜0.05).In pairwise comparison,the absolute number of neutrophil and NHR were significantly different among the three groups.BMI was significant different between non-CHD group and Syntax medium-high-risk group.HDL-C,fasting blood glucose and glycosylated hemoglobin were significant different between Syntax low-risk group and non-CHD group,as well as between Syntax medium-high-risk group and non-CHD group(P＜0.05).Creatinine and APOB were significant different between Syntax low-risk group and non-CHD group.Triglyceride,VLDL-C and LP(a)were significant different between Syntax low-risk group and Syntax medium-high-risk group(P＜0.05).Pearson correlation analysis showed a positively correlation between NHR and Syntax score(r=0.322,P＜0.01).Univariate and multivariate binary logistic regres-sion analysis showed that NHR(OR=1.265,95％CI1.097～1.458,P＜0.05)was an independent risk factor for the severity of coronary artery lesions in young adults with acute myocardial infarction.Subgroup analysis showed that NHR was significantly associated with the severity of coronary artery lesions in patients with BMI≥24 kg/m2,smokers,drinkers and non-drinkers(P＜0.05).No significant difference was observed in interaction analysis.The ROC curve showed that the area under the curve(AUC)predicted by NHR for acute myocardial infarction in young adults was 0.758,with a cut-off value of 7.0319,sensitivity of 83.3％,and specificity of 63.53％.Conclusion NHR has a certain value in predicting the severity of coronary artery lesions in young adults with acute myocardial infarction.
RESUMO
Background: Endoscopic submucosal dissection has become the preferred treatment for early gastric cancer without lymph node metastasis (LNM). The risk of LNM is different among different pathological types of early gastric cancer. Aims: To investigate the risk factors of LNM in patients with early gastric cancer. Methods: The clinicopathological features of 1 093 early gastric cancer patients underwent radical gastrectomy and diagnosed by pathology from January 2005 to December 2019 at Nanjing Drum Tower Hospital and Nanjing Gaochun People's Hospital were retrospectively analyzed. Risk factors of LNM in patients with early gastric cancer were analyzed by univariate analysis and logistic regression model analysis. Results: A total of 1 093 patients with early gastric cancer were enrolled, and positive LNM was found in 154 patients (14.1%). Univariate analysis showed that gender, age, tumor size, tumor location, gross classification, depth of tumor invasion, vascular and nerve invasion, differentiation type, ulcers were related with LNM (P<0.05). Multivariate analysis showed that age (OR=1.654, 95% CI: 1.102-2.480, P=0.015), tumor location (OR=1.617, 95% CI: 1.227-2.131, P=0.001), differentiation type (OR=1.664, 95% CI: 1.205-2.298, P=0.002), depth of invasion (OR=1.569, 95% CI: 1.212-2.030, P=0.001), vascular invasion (OR=10.514, 95% CI: 6.353-17.401, P=0.000) were the independent risk factors of LNM in early gastric cancer. Conclusions: Age, tumor location, differentiation type, depth of invasion, and vascular invasion are the independent risk factors of LNM in early gastric cancer, especially vascular invasion. For patients with vascular invasion, if there are no contraindications, surgical intervention is recommended.
