Objective To observe the effect of adjusting high dietary profein intake on nutritional status of peritoneal dialysis (PD) patients. Method Thirty three PD patients whose daily protein intake (DPI) was over 1.2g/(kg? d) were included in study from July, 2005 to November, 2006. A recipe was given by a professional dietitian for every patient to reduce DPI meanwhile maintaining sufficient daily energy intake (DEI). DPI, DEI, serum albumin (ALB), lean body mass(LBM) and subjective global assessment(SGA) and the prevalence of hyperphosphatemia, hyperkalemia and metabolic acidosis were evaluated before and after 3 and 6 mo adjustment. Results At the end of observation, 28 patients were enrolled in the study. Their mean age was 61.37?12.25 yrs, 11 males and 17 females with dialysis period 8.8 mon (1～66 mo). DPI and DEI were significantly decreased during 6 mo (P=0.000). Nobody complained about gastrointestinal symptoms, and the quality and satisfaction of life during the study were not significantly different. Serum Alb at 3 rd month was higher than the start of study (36.22?2.79g/L vs 37.34?3.32 g/L,P

2?l 10% ricin were injected into the pelvic nerve of cats. After 3～5 survival days 20% HRP solution was injected into the ipsilateral lateral parabrachial nucleus, 2～3 days later the animals were perfused with paraformaldehyde and glutaraldehyde, the brain and spinal cord were removed and processed for light and electron microscopy. It was confirmed that the primary afferent terminals (degenerated) of pelvic nerve formed axo-dendritic and axo-somatic synapses with the retrograde labelled neurons projected to the lateral parabrachial nucleus which were located in the dorsal commissure nucleus (DCN), intermediolateral nucleus (IML) and lamina Ⅰ of sacral spinal cord. Hence, the secondary afferent pathway of pelvic visceral sensation, as. indicated at the ultrastructural level, might originate from DCN, IML and lamina Ⅰ of sacral spinal cord and project to the lateral parabrachial nucleus.

The Nissl and Golgi staining methods and electron microscopy were u(?)o investigate the architecture of dorsal commissure nucleus (DCN) of the sacral spinal cord in cat. A morphologically specific nucleus could be identified in the medial part of the lamina Ⅵ of dorsal horn. The nucleus located beside the dorsal funiculus at the lumbar level and gradually moved toward the midline of the dorsal gray commissure in the ventromedial direction as the dorsal gray commissure enlarged at the segments S_(1-2) and two ellipsoid nuclei was formed at the two sides of the midline. A large triangular nucleus was gradually formed by fusion of the two nuclei at S_3-Co_1. Golgi stain positive neurons could be classified into three types: (1) small-triangular neurons (60%); (2) fusiform neurons (30%); (3) oval and irregular neurons (10%). The cell organells of most neurons were plentiful. The cell nucleus was irregular and often with deep invaginations. A large number of free ribosomes and saccules could be found in the canals formed by the nuclear invagination. There were axo-dentritic, axo-axonic, axo-somatic synaptic contacts in the DCN with percentages of 89%, 6%, and 5% respectively. The serial synapse, axo-spinous synapse and crest synapses could also be found.

Objective: To review the experience of using the transit time flow measurement(TTFM) in coronary artery bypass grafting(CABG). Methods: From Sept.2001 to May, 2002,90 cases underwent CABG. Among them, 40 cases with off-pump beating heart (OPCAB) and 50 with conventional coronary bypass grafting. All graft patency were verified intraoperatinlly with TTFM. The flow value of left internal mammary artery (LIMA) in 30 cases was also detected by the same way before grafting to left anterior descending (LAD). Results: There was no operative death and severe complications. The mean flow value of LIMA in 30 cases was (42.9?33.0)ml/min. The actual blood flow value, measured simultaneously by exsanguination was (37.4?28.8)ml/min. Excellent correlation was demonstrated. The mean pulsatility index value (PI) was 1.00?0.04. The flow curve showed both diastolic and systolic filling. The mean flow value of LIMA to LAD, saphenous vein graft (SVG) or radial artery (RA) to circumflex coronary artery (LCX) or diagonal (D), SVG or RA to right coronary artery (RCA) or post anterior artery (PDA) were (29.9?9.5)ml/min, (33.7?17.5)ml/min and (31.5?19.2)ml/min. The PI values were 2.47?0.88, 4.00?1.90 and 2.60?1.30, respectively. The typical flow curve was shown in all LIMA to LAD, and SVG (or RA) to LCX (or D). Blood flow filling was mainly during diastole with minimal systolic peaks during the isovolumetric ventricular contraction. SVG or RA to RCA presents a particular flow pattern characterized by a dual filling. 6 grafts were revised basing on unsatisfied flow curves, PI, and the mean flow or all of them. Significant technical error such as conduit kinking, stenosis of distal anastomosis was found. Conclusion: The patency of graft in CABG can be verified in intraoperatively by use of TTFM. The decision of checking or revising a graft can be made basing on parameters acquired from the TTFM device. To correctly analyze the parameters warrants good clinical results.

0.05).However,body mass index and hemoglobin level were significantly higher in the slow coronary flow group compared with the control group(26.9?3.2 kg/m2 vs.24.9?2.9 kg/m2,P

Baseline shift has severe effects on the analysis and processing of ECG. Filter and baseline polynomial-fitting are the main methods for removing baseline interference. This paper discussed the filtering ways of morphology filter,median filter,Linear-phase finite impulse response (FIR) filter,wavelet transform,morphology and wavelet combined method,median filter and wavelet combined method,comparing with the approach of baseline polynomial fitted way which composed of differential method and coordinates method. Experimental results showed that the poly-fitting approach are more efficient,had certain adaptive quality and little distortion,while filter ways were easy to implement but not accurate enough. As for real time and accuracy,polynomial fitted way has an advantage over filtering ways. Under the circumstances of having great difficulty in extracting baseline points,it is more appropriate to use filter ways to eliminate baseline wandering. This paper compared the methods in common use for suppressing baseline wander so as to help users to choose the proper way.
