Objective:To analyze plaque characteristics of non-culprit coronary lesions with cholesterol crystals in patients with acute myocardial infarction(AMI) by using optical coherence tomography(OCT). We also investigated the potential association between cholesterol crystals with plaque rupture and healed plaque at non-culprit segment.Methods:This study was a retrospective cohort study. Between January 2017 and December 2017, patients with AMI who underwent 3-vessel OCT imaging were included in this study. Patients were divided into two groups according to the presence or absence of cholesterol crystals at the non-culprit lesions. All patients underwent coronary angiography and OCT examination, and non-culprit plaque characteristics were compared between the two groups. The generalized estimating equation log-binomial multirariate regression model was used to assess the relationship between non-culprit lesions with cholesterol crystals and plaque rupture and plaque healing. The follow-up data collection ended in October 2023. Kaplan-Meier survival curves were plotted, and log-rank tests were used to compare the cumulative incidence of major adverse cardiovascular events between the two groups.Results:A total of 173 AMI patients were included (aged (56.8±11.6) years; 124 men (71.7%)). Among 710 non-culprit lesions identified by OCT, there were 102 (14.4%) in cholesterol crystals group and 608 (85.6%) in non-cholesterol crystals group. Compared with non-culprit lesions without cholesterol crystals, those with cholesterol crystals had smaller minimum lumen diameter, severer diameter stenosis, and longer lesion length (all P<0.01). The prevalence of plaque rupture (17.6% (18/102) vs. 4.9% (30/608), P=0.001) and thin-cap fibroatheroma (31.4% (32/102) vs. 11.5% (70/608), P<0.01) was higher in the cholesterol crystals groups than in the non-cholesterol crystals group. In addition, vulnerable plaque characteristics such as (44.1% (45/102) vs. 25.8% (157/608), P<0.01), macrophages were more frequently observed in non-culprit lesions with cholesterol crystals. The generalized estimating equation log-binomial multivariate regression analyses showed that non-culprit cholesterol crystals were positively correlated with healed plaque ( OR=1.583, 95% CI: 1.004-2.495, P=0.048). Conversely, cholesterol crystals were not associated with plaque rupture ( OR=1.632, 95% CI: 0.745-3.576, P=0.221). The follow-up time was 2 142 (1 880, 2 198) days. Non-culprit cholesterol crystals were not related to the major adverse cardiovascular events in patients with AMI (log-rank P=0.558). Conclusions:Among AMI patients, non-culprit lesions with cholesterol crystals presented with severer luminal stenosis and increased plaque vulnerability. The presence of non-culprit cholesterol crystals was associated with rather than plaque rupture.

Objective To investigate the correlation of hs-CRP and systemic immunoinflammatory index(SII)with the severity of coronary artery stenosis in elderly T2DM patients.Methods A retrospective trial was conducted on 158 elderly T2DM patients admitted to the Affiliated Hospi-tal of Xuzhou Medical University from August 2021 to August 2023.According to the results of coronary angiography,they were divided into mild(Gensini score≤60,79 cases)and severe steno-sis groups(＞60,79 cases).Spearman correlation analysis and logistic regression analysis were ap-plied to analyze the correlation and the risk factors for severe stenosis.Results Significantly high-er hs-CRP and SII were observed in the severe stenosis group than the mild stenosis group(P＜0.01).Hs-CRP,SII,glycosylated hemoglobin,neutrophils,hsTNT,NLR,and PLR were positively correlated with Gensini score(r=0.424,P＜0.01;r=0.367,P＜0.01;r=0.207,P＜0.01;r=0.259,P＜0.01;r=0.187,P＜0.05;r=0.317,P＜0.01;r=0.256,P＜0.01),and the course of T2DM was negatively correlated with Gensini score(r=-0.224,P＜0.01).Multivariate logistic regression showed that hs-CRP and SII were independent risk factors for severity coronary artery stenosis in elderly T2DM patients(OR=3.191,95％CI:1.847-5.513,P=0.000;OR=1.006,95％CI:1.004-1.009,P=0.000).Conclusion Elderly T2DM patients have higher levels of hs-CRP and SII,which may be independent risk factors for the pathogenesis of coronary stenosis.

Objective:To investigate the influence of the prevalence and co-prevalence of risk factors for metabolic syndrome on the scores of different levels of metabolic syndrome in people receiving physical examination in Urumqi.Methods:Using the 2017 Xinjiang Health Examination Database, a total of 175 927 people from 7 districts and 1 county in Urumqi were selected as subjects. Face-to-face survey and body measurements were used to collect cardiovascular risk factors and metabolic syndrome scores. Metabolic syndrome scores were used. For the 0-5 points at 6 levels, χ2, χ2 trend test, correlation analysis of ordered variable Kendall’s tau-b, and logistic regression analysis of ordered results were used to analyze the influence of prevalence and co-prevalence of behavioral risk factors on the MS scores. Results:The percentages of 6 metabolic syndrome scores in the sample population were 23.82 %, 27.87 %, 22.41 %, 16.03 %, 8.02 %, and 1.85 %, respectively. The scores of metabolic syndrome were different in different age groups, ethnic groups, groups with different drinking rates, and groups with different dietary types, with the differences all significant ( P<0.05).The MS score in men increased with the increase of oil/salt rate and excessive drinking rate ( P<0.01). The score in women increased with the increase of the current smoking rate, oil/salt rate, and increased with the decrease of physical activity ( P≤0.01). There was no significant difference in the distribution of regular drinking rates between different score groups ( P>0.05). The scores of metabolic syndrome increased with the increase of risk factors ( P<0.05). Ordered results logistic analysis found that in the men with ≥3 risk factors and the metabolic syndrome score was 1.15 (1.06-1.26) times higher than that in the men without risk factor, as well as in women with 2 risk factors and≥3 risk factors. The metabolic syndrome scores were 1.38 (1.22-1.55), 2.02 (1.53-2.66) times higher than those in the women without risk factors. Conclusions:The physical examination group in Urumqi, the more the metabolic syndrome disease behavior risk factors clustered, the higher the metabolic syndrome score was. Therefore, comprehensive intervention measures should be taken to control the different forms of metabolic syndrome to prevent the occurrence and progress of the disease.

Objective To compare the effect and safety of stenting versus directional atherectomy (DA) in the treatment of TASCⅡ A and B superficial femoral artery lesions.Methods 100 patients with TASC Ⅱ A and B lesions were divided into percutaneous transluminal stenting(PTS) group (n =50) and DA group (n =50).Patients were compared in terms of technical success rate,treatment success rate,first operation cost,postoperative ankle brachial index (ABI),limb salvage rate,survival,and patency.Results The technical success rate in both PTS and DA group was 100％.The treatment success rate was 98％ vs.86％,P＞0.05.Postoperative ABI:0.82 ±0.19 vs.0.80 ±0.27,P＞0.05.First operation cost:(34 820 ± 1 051) yuan vs.(45 635 ± 1 358) yuan,P ＜0.001;All patients were followed-up for up to 2-year,the cumulative patency rate was 81.6％ vs.72.9％ (P＞0.05).Limb salvage rate was 97.9％ vs.93.8 ％,P ＞ 0.05.Conclusion There were no significant differences in the effect and safety of PTS versus DA in the treatment of TASCⅡ A and B superficial femoral artery lesions.

OBJECTIVETo investigate the effect of smoking cessation on the risk of cancer among male subjects.

METHODSParticipants of this study were derived from the workers in Kailuan Group who took the health check-up examination in its 11 affiliated hospitals. The check-up examinations were given biennially based on uniformed standard. From May 2006 to December 2011, health examinations were given for 3 rounds and a total of 104 809 male workers involved. The date of being enrolled in this study was defined as that of taking first check-up, and the date of end-of-observation was defined as that of cancer diagnosis, death or end of follow-up.

INCLUSION CRITERIAage ≥18 while being enrolled in this study, and there was no information missing in the questionnaire for age (or date of birth), smoking status, the age of starting smoking, the age of quitting smoking, and smoking amount. The information of smoking status was collected by questionnaires, and the information of newly-diagnosed cancer cases was obtained by follow-up. After adjusted for age, education background, drinking habits, working environment and BMI, multi-variate Cox proportional hazard regression models were used to analyze the association between smoking cessation and cancer risk (all sites of cancers, smoking-related cancers, and lung cancer) by calculating the values of HR (hazard ratio) and 95% CI (confidence interval).

RESULTSTotally, 104 809 subjects were followed up for 450 639.6 person-years, including 46 013 smokers (43.90%), 51 624 never-smokers (49.26%), and 7 172 smoking quitters (6.84%). Among all these subjects, 1 323 were diagnosed as cancer cases, including 1 082 smoking-related cancers, of which 378 were lung cancer cases. The results showed that, compared with never-smokers, smokers had increased risks for all sites of cancers (HR=1.38, 95% CI: 1.20- 1.59), smoking-related cancers (HR=1.45, 95% CI: 1.24- 1.69) and lung cancer (HR=1.70, 95% CI: 1.31- 2.21). While compared with the smokers, smoking quitters had decreased risk of lung cancer (HR=0.36, 95% CI: 0.20- 0.65). For the smokers with smoking history ≥20 pack-years, HR (95% CI) of lung cancer incidence was 0.09 (0.01- 0.65). For people age ≥60 smoke quitter, HR (95% CI) of lung cancer incidence was 0.33 (0.16- 0.68). For people who quit ≥10 years, HR (95% CI) of lung cancer incidence was 0.19(0.06- 0.58).

CONCLUSIONSmoking cessation might decrease the risk of lung cancer among male smokers. The risk of lung cancer was lower among the smoking quitters with longer history of smoking, older age, and longer years of quitting smoking.
