To evaluate the effect of preoperative serum alpha-fetoprotein(AFP) level to total tumor volume (TTV) ratio as a prognostic marker on predicting the tumor recurrence and overall survival time of patients with hepatocellular carcinoma (HCC) after liver transplantation. One-hundred eight patients with HCC who underwent liver transplantation in Beijing Chaoyang Hospital from April 2013 to October 2017 were studied. Divided into AFP/TTV≤2 group and AFP/TTV>2 group by the best cut-off score calculated by receiver operation characteristic curve, the clinical and pathological data of the patients in two groups were compared to explore the relationship between AFP/TTV and tumor recurrence together with the prognosis of HCC patients after liver transplantation. ⋯ The tumor recurrence and the prognosis of patients with HCC after liver transplantation is affected by many factors. AFP/TTV ratio has important predictive value for the tumor recurrence and the prognosis of patients with HCC after liver transplantation. AFP/TTV>2 is an independent risk factor for both early tumor recurrence and poor prognosis of patients with HCC after liver transplantation.

There was a controversy for the electrocardiogram (ECG) changes and their relationship with disease severity in old patients with acute cerebral ischemic stroke (CIS). This study was aim to provide referential data for this topic. Totally 200 old patients with acute CIS in our hospital from January 2017 to December 2019 were included into this study. ⋯ There were statistically significant differences of myocardial ischemic ST-T segment changes among different disease severity, infarct size and prognosis of acute CIS patients (P < .05). The ischemic ST-T segment changes of ECG reflected that the disease severity, and more ECG abnormalities indicated more severe pathological conditions in CIS patients. The characteristics of ischemic ST-T segment changes have important reference value in the evaluation of severity and prognosis of acute CIS in old patients.

Endoscopic procedures increase the risk of transmission of severe acute respiratory syndrome coronavirus 2 to medical staff, because aerosols are generated during upper gastrointestinal endoscopy. There have been several reported studies on devices for infection prevention; however, few reports have validated them. ⋯ The mean number of microdroplets was significantly smaller in the group that used the novel mask (57.9 ± 122.91 vs 933.6 ± 119.80 droplets; P = .01). The novel mask may aid in reducing the degree of exposure of medical personnel to microdroplets and the risk of subsequent infection.

In this study, corona virus disease 2019 (COVID-19) transmission networks were built to analyze the epidemic situation of COVID-19 in Liaoning and Jilin provinces in early 2020. We explore the characteristics of the spread of COVID-19, and put forward effective recommendations for epidemic prevention and control. We collected demographic characteristics, exposure history, and course of action of COVID-19 cases. ⋯ The main transmission routes of the local cases in the 2 provinces were the family members, and the infection of the imported cases were mainly occurred in public places. It was estimated that the unidentified asymptomatic infected cases in the 2 provinces account for approximately 7.3% of the total number of infected cases. The length of the transmission chain suggests that the spread of COVID-19 can be effectively controlled with effective prevention measures.

Meta Analysis
Immunoadsorption treatment for dilated cardiomyopathy: A PRISMA-compliant systematic review and meta-analysis.
As one of the leading causes of heart failure, dilated cardiomyopathy (DCM) is characterized by dysfunctional muscle contraction and enlarged ventricular chamber. Patients with DCM have been shown to respond well to immunoadsorption (IA) therapies. However, the efficacy and safety of IA treatment for DCM patients remained to be evaluated. ⋯ Results of this meta-analysis indicated that the IA treatment can improve the left ventricular ejection fraction, reduce left ventricular end diastolic diameter, and thus improve clinical outcome in DCM patients. However, further evidence are required to validate the relative safety of IA treatment. Multi-center, double blind studies should be conducted to elucidate the precise effect of IA treatment in DCM patients.
