Objective To report the clinical experience of extracorporeal membrane oxygenation (ECMO)in the emergency management of fulminant myocarditis.Methods The patient,an 11 year-old boy,had fever for 4 day and abdominal pain,vomiting for 1 day and anuria for 12 hours.Electrocardiogram showed Ⅲ atrial-ventricular block,multifocal ventricular rhythm,bundle branch block,convulsivum multifocal ventricular tachycardia,extensive low voltage,ST-T elevation at lead Ⅰ,AVR,V1,V2,V3;and there were ST-T intrusion,T wave inversion at lead Ⅱ,Ⅲ,AVR,AVF,V4～5.Blood creatine kinase was 2 161 U/L,reatine kinase isoenzyme 109 U/L,α-hydroxybutyrate dehydrogenase 612 U/L,lactate dehydrogenase 696 U/L,troponin Ⅰ 22.1 U/L.Echocardiogram showed right atrium 4.4 mm,right ventricular 2.3 mm,severe tricuspid valve regurgitation,left ejection fraction 33％,left ventricular fractional shortening 15％,ventricular wall motion dyssynchrony.Blood lactate was 4.0 mmol/L.The patient's condition was still unstable after using dobutamin,dopamine,milrinone,furosemide,large dose methylprednisolone,intravenous human immunoglobin,phosphocreatine and so on.ECMO was used for cardio-pulmonary support.It is necessary to monitoring the consciousness,temperature,heart rate,respiration,blood pression,SaO2,urinary volume,ariterial blood gas,blood electrolytes,blood lactate,blood glucose,liver function,renal function,blood routine,activated clotting time(ACT),lower extremity blood supply and so on.ACT was maintained at 160～200 s.Heparin was used persistently[5～10 U/(kg·min)].Results ECMO system had been successfully used for 7 days.The cardiac function of the patient was improved significantly.There was no complication,such as hemorrhage,infection,and embolism.Heart arrest in the patient occurred three times,ventricular fibrillation and ventricular flutter occurred one time respectively during ECMO.The rhythm was recovered by electric defibrillation and antiarrhythmic drugs.On day 20,the patient was discharged.At the time of hospital discharge,the patient demonstrated good activity,with normal myocardial enzymes.The echocardiogram showed the size of the cardiac chambers and the contractile function of the myocardia were normal.Electrocardiogram showed Ⅰ degree atrial-ventricular block,complete right bundle branch block.Two weeks later,the electrocardiogram demonstrated complete right bundle branch block.Echocardiogram showed septal thickening(0.9 cm).Two months later,the electrocardiogram was just as that of two weeks before.Echocardiogram showed septal thickening(0.7 cm).The children had no symptom after he was discharged and acted without limitation.Conclusion ECMO is a kind of effective treatment for fulminant myocarditis.The key to desirable therapeutic effect is the timing of its application.

Objective To evaluate the curative effect of self-made layering fibula feet cushion to prevent deep venous thrombosis(DVT) after hip replacement(HR).Methods Totals of 100 patients applied THA divided into two groups-experimental group and control group on average randomly.The experimental group utilized self-made layering fibula feet cushion while the control group applied general feet cushion to prevent DVT.To compare the rate of DVT, the length of swelling vanishment, Harris hip score and the length of hospitalization had been used as effect evaluation.Results Comparing with control group, the rate of DVT (14%), the length of swelling vanishment(4.90 ±1.75) d, Harris hip score(82%) and the length of hospitalization experimental group(7.47 ±1.81) d, the experimental group acquired 4%, (4.47 ±1.28) d, 96%and (6.80 ±1.26)d,respectively.The length of hospitalization and the length of swelling vanishment had statistical significance (t=-3.034,-1.986,respectively;P<0.05).The results of rate of DVT and the rate of hip functional improvement had statistical significance as well (χ2 =4.031, -3.129, respectively;P <0.05).Conclusions The self-made layering fibula feet cushion can effectively prevent DVT after total hip replacement and are strongly recommended for clinic nursing comprehensively.

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 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.

Objective To analyze results of breast cancer screenings in the Cancer Screening Program in Urban China (CanSPUC) during 2012-2013. Methods In 14 cities of 9 provinces (Eastern Region: Beijing, Hebei, Liaoning, Shandong and Guangdong; Central Region: Heilongjiang and Hunan;Western Region: Chongqing and Gansu), 198 097 women aged 40-69 years who had lived in their cities for ≥3 years were surveyed through a cancer risk assessment questionnaire during 2012-2013. The questionnaires identified women considered to be at high risk for breast cancer, of whom 17 104 received screening examinations, for whom complete records of breast cancer screening and other data were available for 12 440 subjects altogether, including breast ultrasound exams for subjects 40-44 years old. Subjects older than 45 years or in whom breast imaging reporting and data system (BI-RADS) ultrasound had found≥3 lesions also underwent mammography. In this cohort, BI-RADS 3 class was defined as suspicious and BI-RADS ≥4 class as positive. Chi-square tests were used to compare breast cancer screening results by groups. Results As of October 2013, breast cancer screening percentages for the 12 440 subjects for whom full data were available were, by region, Eastern: 55.43% (6 895); Central: 21.45% (2 669); and Western:23.12% (2 876); by age, 40-44 years: 5.50% (684); ≥45 years: 94.50% (11 756). Using BI-RADS, 2018 subjects were found to have 3 lesions (detection rate:16.22%), which were distributed regionally as Eastern:19.00% (1 310 women), Central: 13.75% (367) and Western; 11.86% (341); χ2=91.45, P<0.001; and 289 were found to have≥4 lesions (detection rate:2.32%), which were distributed regionally as Eastern:2.41%(166), Central:1.54%(41) and Western;2.85%(82);χ2=11.04, P=0.004. Women aged 50-54 years had the highest detection rate of BI-RADS 3 lesions at 18.74% (561/2 994), and those aged 40-44 years had the highest detection rate of BI-RADS ≥4 at 2.92% (20/684). Conclusion Detection rates of BI-RADS ≥4 lesions were highest in the Western region and in women aged 40-44 years, and lowest in the Central region and in women aged 60-64 years. Detection rates of BI-RADS 3 lesions were highest in the Eastern region and in women aged 50-54 years and the lowest in the Western region and in women aged 60-64 years.

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.
