Objective To evaluate the efficacy and safety of fibrinolysis strategy in patients with acute ST-segment elevation myocardial infarction (STEMI) during the COVID-19 epidemic, and to provide reference value for optimization of fibrinolytic process on the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff. Methods The efficacy and safety of fibrinolysis were retrospectively analyzed in 7 patients with acute STEM, who hospitalized from February 29, 2020 to April 3, 2020 in the Department of Cardiology, Wuhan Union Hospital of Tongji Medical College, Huazhong University of Science and Technology. To optimize the fibrinolytic process on the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff, a full-time medical team in charge of fibrinolysis under third-grade protection was established. The acute STEMI patients were treated immediately in a fixed and isolated area in emergency department before receiving green cnolytic process, the time from the first ECG to fibrinolysis of the last 5 patients were 42, 46, 51, 43 and 54 minutes, respectively，which was significantly shorter than that before optimization. Conclusions During the COVID-19 epidemic, fibrinolysis in patients with acute STEMI is safe, effective and easy to implement. Therefore, it is recommended as the top priority for the patients with acute STEMI with indications for fibrinolysis. On the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff, the duration of myocardial ischemia can be shortened by optimization of the fibrinolytic process.Objective To analyze the prognostic value of myocardial injury in patients with COVID-19. Method Confirmed cases of COVID-19 patients admitted from January 31st to February 5th at isolation ward of Renmin Hospital of Wuhan University were divided into non-survival group （33 cases）and survival group (169 cases)according to the clinical outcomes 5 weeks after admission. Data including demographics, comorbidities, vital signs, laboratory results were obtained. Cardiac injury was defined as serum concentration of high sensitivity cardiac troponin I (hs-cTnI) above 0.04 μg/L. Univariate and multivariate Cox regression were used to analyze the prognostic value of myocardial injury in patients with COVID-19. Kaplan-Meier analysis was used to plotted survival curve and analyze the impact of myocardial injury on the survival outcome of COVID-19 patients. Results A total of 202 patients were included, the age was 63 (51, 70) years old, 88 (43.6%) of them were male, 85 (42.1%) of them had comorbidities, 125 (61.9%) of them were severely to critically ill. Till March 11, 33 patients died, all of them were critically ill patients. The age, proportion of males, comorbidities, respire rate, serum levels of hs-cTnI and incidence of heart failure in the non-survival group were significantly higher than those in the survival group (all P less then 0.05). The hospitalization time of non-survival group was significantly shorter than that of survival group (6(4, 9) vs. 32(23, 36), P less then 0.001). Myocardial injury was an important prognostic factor of COVID-19 (HR=5.382, 95%CI 2.404-12.050, P less then 0.001). Kaplan-Meier survival analysis showed that the presence of myocardial injury was significantly associated with the reduced survival rate among COVID-19 patients (P less then 0.001). Conclusion Myocardial injury is an important prognostic factor of COVID-19, COVID-19 patients with myocardial injury face a significantly higher risk of death.Objective To explore the clinical characteristics of patients with pre-malignant or malignant transformation in ectopic endometrium of adenomyosis. Methods A retrospective study was performed on 4 818 patients received surgical treatment in Peking Union Medical College Hospital and pathologically confirmed as adenomyosis from January 2010 to October 2016. The clinical features and prognosis of 30 patients among these with pre-malignant or malignant transformation in ectopic endometrium were reviewed. Results A total of 4 818 patients pathologically diagnosed with adenomyosis. Among these,30 (0.62%,30/4 818) patients were diagnosed with pre-malignant or malignant transformation in foci of adenomyosis, including 16 (0.33%, 16/4 818) of atypical endometrial hyperplasia and 14 (0.29%, 14/4 818) of endometrioid carcinoma. The average age of 30 patients was (50.8±3.0) years (range 27-65 years). Patients with atypical hyperplasia in foci of adenomyosis coexist with 13 cases of endometrioid carcinoma in situ, 1 case yosis seems not to increase the risk of deep myometrial invasion, lymphovascular space invasion, and recurrence or mortality in patients of adenomyosis with endometrial adenocarcinoma.Objective To explore the efficacy and safety of open cardiac operation and interventional therapy in pregnant patients and describe the feto-neonatal and maternal outcomes. Methods A retrospective study of 39 cases of women undergoing open cardiac operation or interventional therapy during pregnancy was conducted in Guangdong Provincial People’s Hospital from Jan. 2014 to Oct. Harmine 2019. Results The age of 39 pregnant women with gestational heart disease was (30±6) years old (21-43 years old). Among them, 37 cases were single and 2 cases were twin pregnancy. Modified World Health Organization (mWHO) pregnancy risk classification were all level Ⅳ. There were 22 women receiving cardiac operation under cardiopulmonary bypass during pregnancy, 14 patients undergoing percutaneous balloon mitral valvuloplasty, 2 patients accepting percutaneous balloon pulmonary valvuloplasty, and 1 case receiving atrial septal defect occluder with ultrasound guidance. Three were no maternal deaths during and after the operation. One patient had an inevitable abortion. Four fetuses died in the uterine after open cardiac surgery. There patients chose termination of the pregnancy after cardiac operation. There were 31 live birth, in which 7 cases were preterm live birth and 24 patients were term live birth. The total number of newborns were 33. Two fetuses suffered neonatal intracranial hemorrhage and died after birth. Thirty-one fetuses were alive and born without any abnormity. Conclusion For pregnant women with high risk of cardiovascular disease and classified as mWHO pregnancy risk level Ⅳ, cardiopulmonary bypass and interventional therapy during pregnancy could be used as an alternative for better materal and fetal outcomes.
