Objective To investigate the relevant risk factors for cardiovascular autonomic neuropathy (CAN) in diabetic patients. Methods 712 cases of diabetic patients were divided into two groups according to their cardiovascular autonomic function test: one group with CAN (n=160) , and the other without CAN (n=552). Duration of diabetes, profession, body mass index (BMI), blood glucose, lipid profile, glycosylated hemoglobin (HbA1C) and urinary albumin excretion rate (UAER) were measured. Results Duration of diabetes, the levels of fasting plasm glucose (FBG), triglyceride (TG), VLDL-C, APOB, UAER were significantly higher in CAN group than in non-CAN group (P

In this paper,the structure,principle and application of combined chemical oxygenerator is described.Its character is that through the adjustable valve controlled by inspiration and expiration,it offers and halts oxygen supply.The utilization rate of oxygen is over 98%.The physico-chemical indices of the oxygen produced reach the national standard for medical oxygen.The experimental results in alti- tude field have shown that it can alleviate the syndroms of acute mountain sickness and reduce heart rate.

Objective To explore the effect of food improvement on the retention time of nasogastric tube in stroke patients with dysphagia. Methods Sixty cases were assigned to the control group(30 cases) and the experimental group(30 cases) by random digits table method, the control group received routine nasogastric feeding, and the experimental group were given texture modified foods and thickened liquid to try to help them eating through the mouth. The feeding tube was pull out when the person in experimental group was capable of taking texture modified foods and thickened liquid without difficulty,while the tube was pull out when the person in control group was able to eat regular food and drink regular fluids. The retention time of nasogastric tube of two groups was compared. Results The retention time of nasogastric tube was(6.13±2.96)d in the experimental group and(18.93±7.58)d in the control group, there was significant difference (t =-8.162, P<0.01). Conclusions Food improvement can effectively shortenthe retention time of nasogastric tube in stroke patients with dysphagia.
