Research progress on plant-based diets for the prevention and management of chronic kidney disease / 公共卫生与预防医学

Diet management is the key part in the prevention and treatment of chronic kidney disease (CKD). A plant-based diet is a diet consisting mostly or entirely of foods derived from plants, with little or no animal foods. In recent years, research on plant-based diets for chronic kidney disease has been increasing. Large-scale epidemiological studies and interventional studies consistently suggest that plant-based diets could reduce the risk of CKD and related complications and slow down CKD progression. This article reviews the research progress of plant-based diets in the prevention and control of CKD.

Image processing strategies based on visual attention models under simulated prosthetic vision / 中国医疗器械杂志

Visual prostheses have the potential to restore partial vision for the blinds. The stimulating electrodes generate reproducible phosphenes. Still limited by the low resolution vision used in visual prostheses nowadays, it is important to optimize the image processing strategies in order to deliver better visual information to the patients. This paper presents a review of the current research progress on the image processing strategies based on visual attention models under simulated prosthetic vision and related psychophysics.

Image processing system of visual prostheses based on digital signal processor DM642 / 中国医疗器械杂志

This paper employed a DSP platform to create the real-time and portable image processing system, and introduced a series of commonly used algorithms for visual prostheses. The results of performance evaluation revealed that this platform could afford image processing algorithms to be executed in real time.

Study on the relationship between degree of venous injury and the indwelling time by injection of chemotherapy drugs with intravenous catheter system / 中国实用护理杂志

Objective To observe the relationship between degree of venous injury and the indwelling time by injection of chemotherapy drugs with intravenous catheter system. Methods Totally 43 New Zealand rabbits were selected as the study sample. Among them, three rabbits were chosen by lot as a blank control, the others were evenly divided into two groups randomly. The veins at the edges of the two ears were taken out as the tested blood vessels for the infusion with intravenous catheter system. The two groups were injected respectively with physiological saline and chemotherapy drugs once daily, and then blocked with heparin salt water. After intraperitoneal anaesthesia, pathological sections were prepared by taking live samples from the ear vein where intravenous catheter system puncturing on the 2nd, 4th, 6th,8th and 10th day of transfusion. And inflammation and thrombosis in the vein had been observed under the light microscope. Results In the same indwelling time, the inflammatory response of the two groups was compared: no difference on the 2nd day; difference was seen on the 4th、6th and 8th day; but again no difference on the 10th day. Thrombosis compared: no difference on the 2nd, 4th day, but difference was seen on the 6th, 8th and 10th day. Conclusions Chemotherapy drugs has a strong irritant on blood vessels.The indwelling time should not be too long, generally advisable 2 days,even if no abnormal response is observed locally by the naked eye.
