RESUMEN
ObjectiveTo explore the relationship of postoperative systemic inflammatory response syndrome(SIRS) and preoperative midway through the urine and perioperative renal pelvis urine of percutaneous nephrostolithotomy(PCNL).Methods Participants included 450 patients with urinary calculus who underwent PCNL,preoperative midway through the urine and perioperative renal pelvis urine of PCNL was collected.ResultsOf 450 cases,preoperative midway through the urine germiculture positive 100 cases (22.2％,100/450 ),perioperative renal pelvis urine germiculture positive 85 cases (18.9％,85/450),46 cases ( 10.2％,46/450) occurred SIRS after PCNL.Decompression of perioperative renal pelvis urine germiculture positive 20 cases(23.5％,20/85) preoperative midway through the urine germiculture positive,perioperative renal pelvis urine the bacteria cultures negative 80 cases (21.9％,80/365 ) preoperative midway through the urine germiculture positive(P ＞0.05),preoperative midway through the urine germiculture positive 15 cases ( 15.0％,15/100) in SIRS,preoperative midway through the urine the bacteria cultures negative 31 cases ( 8.9％,31 /350) in SIRS (P ＞ 0.05 ).Decompression of perioperative renal pelvis urine germiculture positive 18 cases (21.2％,18/85) in SIRS,perioperative renal pelvis urine the bacteria cultures negative 28 cases (7.7％,28/365) in SIRS (P ＜ 0.05 ).ConclusionPreoperative midway through the urine has no correlation with the occurrence of SIRS,perioperative renal pelvis urine germiculture positive can predict the occurrence of SIRS,giving corresponding antibiotic treatment can improve the security of PCNL.
RESUMEN
Objective To evaluate the protective effects of a novel hyperpolarized cardiac preservation solution on isolated rat heart. Methods Male Sprague Dawley rats (250~300 g, n =24) were randomly divided into three groups ( n =8 in each group) and their hearts were preserved with K H, UW, HCS solution respectively for 24 h. The isolated hearts were perfused in the Langendorff rat mode for functional evaluation before and after preservation. Lactate dehydrogenase and creatine phosphokinase enzyme leakages, contents of adenosine triphosphate and wet weights in myocardium were measured after reperfusion. Results The impairment of the left ventricle function in K H group was serious, while that in HCS and UW groups was mild. The recovery of coronary flow in HCS group was better than K H and UW groups. There were no significant differences in releases of LDH and CPK and wet weight of myocardium between UW group and HCS group. HCS group offered a less variety of pH and had the highest ATP content of myocardium among the three groups. The time, from the reperfusion to beating of heart, showed no difference between UW group and HCS group. The ultrastructural changes were slight in HCS group. Conclusions HCS solution can protect rat heart for 24 h effectively. The recovery of heart function by HCS is similar to that by UW solution. HCS solution can improve the coronary flow and acidosis and protect ATP more effectively than UW solution.
RESUMEN
Objective To investigate the features of kidney transplantation in patients over 60 years old.Methods From May 1998 to Oct. 2001,the clinical data of 81 cases over 60 post kidney transplantation were retrospectively analysed and compared with those of 432 patients below 60 age. Results The dialysis time of senile group was longer and the hypoproteinemia was sever than that of control group (P 0.05). The postoperative incidence of pulmonary infection was higher(P
