AIM: To study the protective effects of n on -mitogenic human fibroblast growth factor (nm-haFGF) on cardiomyocytes injured b y reactive oxygen free radicals. METHODS: The cardiomyocytes were isolated from neonatal SD mouse by trypsin digestion. The cardiomyocytes injury model was established by expos ing the cells to hydrogen peroxide (H 2O 2), and the injury status in cardiomy ocytes were evaluated by examining the cellular viability, measuring cell apopto sis and observing the change of cellular morphology. nm-haFGF was added to the c ulture medium, and the changes of cellular viability, superoxide dismutase (SOD) , malondialdehyde (MDA) and celluar apoptosis were observed. RESULTS: A dose-dependence relation between the concentration of H 2O 2 and the cardiomyocytes injury was observed. 10-80 ?g/L nm-haFGF dose -dependently increased cardiomyocyte viability and the general SOD activity, as well as decreased the content of MDA and the quantity of cardiomyocyte apoptosis . CONCLUSION: The higher the concentration of H 2O 2, the mor e serious the cardiomyocyte injury. nm-haFGF may have a good protective effects on cardiomyocytes treated with H 2O 2.

Objective:To investigate a time series deep learning model for respiratory motion prediction.Methods:Eighty pieces of respiratory motion data from lung cancer patients were used in this study. They were divided into a training set and a test set at a ratio of 8∶2. The Informer deep learning network was employed to predict the respiratory motions with a latency of about 600 ms. The model performance was evaluated based on normalized root mean square errors (nRMSEs) and relative root mean square errors (rRMSEs).Results:The Informer model outperformed the conventional multilayer perceptron (MLP) and long short-term memory (LSTM) models. The Informer model yielded an average nRMSE and rRMSE of 0.270 and 0.365, respectively, at a prediction time of 423 ms, and 0.380 and 0.379, respectively, at a prediction time of 615 ms.Conclusions:The Informer model performs well in the case of a longer prediction time and has potential application value for improving the effects of the real-time tracking technology.

OBJECTIVE:
To better understand the pre-operation evaluation of donor kidneys from extended criteria donation after cardiac death and to improve the management during and after renal transplantation.
METHODS:
Both of the donor kidneys were from the donor who underwent liver transplantation 5 years ago in the Center of Organ Transplantation of Central South University. The donor was admitted because of liver function deterioration which led to hepatic coma, brain death, hepatorenal syndrome and cardiac death sequentially. Deceased donor score (DDS) and "zero point" kidney biopsy were applied to evaluate the donor kidney. After thorough examination of the donor and the renal function, renal transplantation was performed on 2 recipients.
RESULTS:
The recipients were followed up by 6 months, both of whom developed pulmonary infection and relieved after treatments. The kidney grafts functioned well and no surgical complication and no acute rejection occurred during the follow-up.
CONCLUSION
Proper evaluation of the donor organs ensures the safety of renal transplantation with kidneys from cardiac death donors who underwent liver transplantation, which is an important way to increase the number of organs for transplantation, yet the long-term effects need further observation.
