A multicenter study to develop and validate a novel C-GALAD Ⅱ HCC prediction model based on serological markers / 中华检验医学杂志

Objective:To establish a model C-GALAD for detecting hepatocellular carcinoma (HCC) from the chronic liver disease and healthy people based on the serum markers.Methods:A clinical cohort including 229 hepatocellular carcinoma patients, 2 317 patients with chronic liver disease and 982 healthy people, was retrospectively collected from eight hospitals or physical examination institutions from April 2018 to October 2020. The data were divided into a training set and a testing set by stratified sampling with a 6∶4 ratio. A predictive model was established on the training set using a logistic backward regression method and validated on the testing set. In addition, clinical data from March to July 2021 in Beijing You′ an Hospital affiliated to Capital Medical University, including 84 patients with liver cancer and 204 patients with chronic liver disease collected were used for external independent validation of the model. The receiver operating characteristic curve (ROC) area under curve (AUC), the sensitivity and the specificity were used to evaluate the effectiveness of the model.Results:Through the logistic backward regression method, the seven signatures including age, gender, alpha-fetoprotein (AFP), alpha-fetoprotein alloplasm-3 ratio (AFP-L3%), des-gamma-carboxyprothrombin(DCP), platelet (PLT) and total bilirubin (TBIL) were selected as risk factors in the detection model. The area under the ROC curve (AUC) of the model on the testing set was 0.954, with an 88.04% sensitivity and a 94.85% specificity, and the AUC of model on the external independent validation set was 0.943, with an 89.29% sensitivity and a 90.2% specificity, which were better than other published models.Conclusion:The C-GALAD Ⅱ model can accurately predict the risk of hepatocellular carcinoma occurrence, and thus provide a trustworthy diagnosis method of hepatocellular carcinoma.

Effects of Shuanghuanglian oral liquids on patients with COVID-19: a randomized, open-label, parallel-controlled, multicenter clinical trial / 医学前沿

We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.

Multivariate analysis of short-term prognosis of liver transplantation in patients with end-stage liver disease / 中华器官移植杂志

Objective@#To analyze many indicators during perioperative period of liver transplantation in patients with end-stage liver disease, only to seek related factors that can accurately predict short-term(≤three months)outcome.@*Methods@#We analyzed retrospectively clinical data of consecutive patients with end-stage liver diseases undergone liver transplantation in a single treatment center. Logistic regression analysis was used to analyze the perioperative indicators including recipient gender, age, body mass index, preoperative serum albumin level, serum sodium concentration, urea nitrogen level and donor-recipient blood group, et al. Correlated factors were analyzed by the method of multivariate logistic regression. Statistical processing package was SAS 9.1.3 soft. The difference was statistically significant with P<0.05.@*Results@#18/165 patients died within 3 months after transplantation(mortality rate: 10.9 %). According to the result of univariate analysis, the indicators correlated with early mortality which were statistically significant were preoperative serum sodium, blood urea nitrogen, PT-INR, CTP score, MELD score and MELD-Na score. On the base of the result of Logistic multiple regression. However, only MELD-Na score was associated with 3 months prognosis(P=0.001, β=-2.510, OR=0.088, 95 % CI=0.037~0.349).@*Conclusions@#Preoperative MELD-Na score is an independent risk factor for short-term survival in patients with end-stage liver disease. Higher MELD-Na score is, the early mortality is higher.
