Objectives:To explore the predictive value of angiography-derived index of microcirculatory resistance(Angio-IMR)for early prognosis in patients with acute ST-segment elevation myocardial infarction(STEMI)after percutaneous coronary intervention(PCI).Methods:This multicenter study enrolled 1 629 consecutive STEMI patients who underwent successful PCI at three grade A tertiary hospitals(The Second Affiliated Hospital,Zhejiang University School of Medicine;Shengjing Hospital of China Medical University;Renji Hospital,Shanghai Jiao Tong University School of Medicine)from June 1,2017,to May 31,2020.According to postoperative Angio-IMR,patients was stratified into two groups:the Angio-IMR>40 group(n=508)and the Angio-IMR≤40 group(n=1 121).The incidence of major adverse cardiovascular events(MACE;defined as a composite endpoint including cardiac death,heart failure rehospitalization,cardiogenic shock,malignant arrhythmia,cardiopulmonary resuscitation and stent thrombosis)within 1-month post-PCI was compared between the two groups.Results:The median Angio-IMR after PCI was 32.4(22.3,42.6).The cumulative incidence of early-term MACE was significantly higher in patients with Angio-IMR>40,compared to those with Angio-IMR≤40(5.5%vs.2.3%,log-rank P<0.001).Multivariate Cox regression analysis showed that Angio-IMR>40 was an independent predictor of early-term MACE(HR=2.07,95%CI:1.20-3.58,P=0.009).The addition of Angio-IMR enhanced the predicting performance of the clinical risk model to predict early adverse outcomes(AUC:0.820 vs.0.794,P=0.043).Conclusions:In patients with STEMI after PCI,Angio-IMR can predict the occurrence of early-term MACE.The incorporation of Angio-IMR to clinical models significantly improves the model ability to predict early adverse outcomes in these patients.

Purpose To investigate the diagnostic value of 18F-FDOPA PET/CT imaging and semi-quantitative analysis platform for the diagnosis of Parkinson's disease(PD).Materials and Methods There were 27 healthy controls and 56 clinically diagnosed PD patients,including 33 early PD(Hoehn-Yahr class Ⅰ-Ⅱ)and 23 advanced PD(Hoehn-Yahr class Ⅲ-Ⅳ),underwent 18F-FDOPA PET imaging in Nanjing First Hospital,Nanjing Medical University were consecutively enrolled from January 2018 to December 2019.The striatal to occipital ratio(SORs)in radioactivity was calculated by HERMES BRASS platform,thereby completing the semi-quantitative analysis of the brain based on regions of interest and observing the asymmetry of the striatal subregions in early-stage PD and late-stage PD patients.Using artificial intelligence techniques to perform principal component analysis on the SORs of the striatal subregions in PD group and healthy control group,the degree of data aggregation and the distinguishability between groups were observed.Results The SORs was significantly reduced in the whole caudate,anterior,posterior putamen and striatum of advanced PD patients(t=9.02-11.72,P<0.000 1).The area under the curve was 0.952,0.973,0.995 and 0.982,respectively.Compared with the healthy control group,the loss of striatal asymmetry index(mean)in each subregion of the striatum in early PD group was caudate(7.61±5.50)%,anterior putamen(11.43±8.97)%,posterior putamen(17.17±11.63)%,and whole striatum(10.65±7.46)%,respectively.The uptake of 18F-FDOPA in the striatum of PD patients was significantly reduced,and the most obvious loss of early PD patients was contralateral posterior putamen,with a decrease of 34%.Conclusion The platform semi-quantitative analysis of 18F-FDOPA PET/CT images provides objective semi-quantitative values for early diagnosis and differential diagnosis of PD.Asymmetry in the striatum,especially in the putamen,may be an important parameter for early diagnosis of PD..

OBJECTIVE: To compare the effects of medical ozone oil and urea ointment for prevention and treatment of hand-foot skin reaction (HFSR) caused by sorafenib in patients with hepatocellular carcinoma (HCC). METHODS: A total of 99 patients diagnosed with advanced HCC according to National Comprehensive Cancer Network (NCCN) who were scheduled to receive sorafenib treatment for the first time were enrolled in this study between April, 2018 and January, 2020. The patients were randomized into medical ozone oil group ( RESULTS: Eight patients were excluded for poor compliance or protocol violations, leaving a total of 91 patients for analysis, including 44 in medical ozone oil group and 47 in urea ointment group. Sixteen (36.4%) of patients in ozone oil group developed HFSR, a rate significantly lower than that in urea ointment group (57.4%; CONCLUSIONS Medical ozone oil can significantly reduce the incidence and severity of HFSR to improve the quality of life of HCC patients receiving sorafenib treatment.

Objective To describe the prevalence and characteristics of bladder carcinoma of Shenzhen residents in recent 10 years and make a relative comparison of corresponding data so as to provide basis for the prophylaxis and treatment of Shenzhen. Methods We collected the data of bladder cancer from 2003 to 2012 in Shenzhen and made a statistical analysis of gender, age, crude incidence rate,standardized incidence and other indexes in China of permanent population and registered population in Shenzhen, then we compared the incidence the trends of the two groups. Results Bladder cancer incidence in Shenzhen for the past decade was as follows. For the permanent residents, the incidence in male and female and total incidence of the disease were 2. 37/105 , 0. 75/105 and 1. 63/105 respectively; for the population of male, the incidence in male and female and total incidence of the disease were 4. 77/105 , 1. 19/105 , 3. 09/105 respectively;standardized incidence in China were 17. 1/105 , 4. 53/105 , 11. 21/105 respectively; all of which were higher than the national average level. Conclusions The registered population of Shenzhen has a higher bladder cancer incidence that even reaches the level of developed countries. Therefore, the task of prophylaxis and treatment are arduous.
