20 normal males were examined by BIODEX isokinetic test and rehabilitation system,and data collected were used to observe the influence of angle and time on the isokinetic concentric constriction of knee joint. It was found that angle and time, especially angle factor obviously affected the testing results.

Objective To study the change of angiotensin Ⅱ in the applications of pumpless ECMO, and its effect on prognosis of the acute respiratory failure. Methods The study was performed in ten dogs [ weight 18 - 35 kg, mean weight ( 23.4 ± 4.7 ) kg].A respiratory failure animal model was established end then was treated by bilateral femoral artery-venous ECMO. Collection right atriurn blood end constitution of lung at different time (before ECMO, during ECMO 1h, 2h, 3h, 4h). Angiotensin Ⅱ content in blood and lung homogenate was detected by radio-immunity mothod. Angiotensin Ⅱ expression loci in lung were detected by immunohistochemistry mothod. Results Angiotensin Ⅱ content in plasma was decreased at completion of the model, it was back up at 1 hour and reached the peak at 3 hours, then it slowly declined. Angiotensin Ⅱ content in lung homogenate increased at the beginning, peaked by 2 hours, end then it decreased. Loci angiotensin Ⅱ in lung by immunohistochemistry were expressed in most of epithelial cells cytoplast of bronchiole dissepimont, smooth muscle cell cytoplast of small blood vessel around it end a few macrophage cytoplasts during the model time..Conclusion It is valuable to measure engiotensin Ⅱ in blood through the bilateral femoral artery-venous ECMO, because it can reflect angiotensin Ⅱ in lung and the resume of lung in certain degree.

Objective To investigate the experiences of combined liver-kidney transplantation (CLKTx).Methods Six patients underwent CLKTx in our center. The primary diseases included chronic glomerulonephritis and post-hepatitis B cirrhosis in 4 patients, hepatitis B virus associated nephritis and primary hepatocellular carcinoma in 1 patient, and polycystic kidney and polycystic liver in 1 patient. Cyclosporine A (or tarcrolimus), mycophenolate mofetil and methylprednisolone were applied to prevent rejection. Four cases of post-hepatitis B cirrhosis received lamivudine. And hepatitis B immunogloblin was given to 4 patients for a short term.Results All 6 liver grafts had good primary function. Five renal grafts had good primary function within one week post-transplantation. One patient with delayed kidney graft function needed supportive hemodialysis. The serum creatinine was declined to normal level 52 days post-operation. Pleural effusion occurred in all 6 patients among which 2 patients needed surgical drainage. Two patients had to be treated for bacterial pneumonia and pneumocystis carinii pneumonia respectively. Three patients needed lipid-lowering therapy at early time post-operation. At the last follow-up, all 6 patients were alive with normal renal graft function and liver graft function. The panel reactive antibody (PRA) of one patient was 23 % before transplantation, and remained at about 8 % post-transplantation. The serum HBsAg and HBV DNA of all 4 post- hepatitis B cirrhosis patients became negative post-transplantation.Conclusion CLTx is a safe procedure for combined hepatic and renal end-stage disease with excellent short-term results.

normal males were tested by BIODEX isokinetic test and rehabilitation system and its closed chain attachment.The results show that Peak Torque,Peak Torque/Body Weight,Time to PT,Total Work,Total Work/Body Weight and Average Power were higher when extention than flexion.There were no significant influence on D1/D2 ratio.And the results with closed chain are the same with non closed chain test.

Objective To explore the feasibility and effect of combined piggyback orthotopic liver and kidney transplantation in patient with renal graft function failure complicated with cirrhosis. Methods One patient with renal graft function failure complicated with cirrhosis was resected of renal graft. Daily dose of 50?mg CTX was given 5 days after operation and continued for 3.5 months. After two courses of plasma exchange, PRA was reduced from 66?% to 23?% . Combined kidney and liver transplantation was performed simultaneously using piggyback orthotopic liver transplantation technique,and the kidney graft was placed retroperitoneally in left iliac fossa. PRA was monitored every 30 min after liver reperfusion. Postoperative immunosuppressive therapy consisted of FK506, MMF and steroids. Results The kidney and liver grafts functioned normally after transplantation. PRA was reduced from 23?% to 5?% and maintained at 8?% . HBsAg and HCV were returned to negative. Kidney and liver grafts functioned well during a follow up of 3 months. Conclusion Combined liver and kidney transplantation is an effective rescue for loss of kidney graft complicated with cirrhosis, and liver graft can provide protection towards the kidney graft from the same donor.

Objective: To study the psychological status and influencing factors in patients with nephritic syndrome(NS) before and after percutaneous renal biopsy(PRB).Methods: 235 cases of NS were examined by Symptom Check List-90(SCL-90) and STAI 24 hours before and 6 hours after PRB.Results: Before PRB,factorial anxiety and phobic anxiety were higher than norm,while after the procedure,only somatization score was still higher than norm;In men,there was a higher score than that of women after PRB,all indices were seen decreased significantly;Higher scores were seen in under-60 years old than over-60 years old.Conclusions: Before and after PRB,many factors were involved in and responsible for patients' psychological symptoms.

AIM To explore a long-term Kupffer cell culture method, which can best maintain the function and activity of cell and decrease the cellular damage. METHODS Lactic dehydrogenase (LDH) in the supernatants were measured to observe the severity of cellular damage ,the function of Kupffer cell was reflected with the nitrogen monoxide(NO) content and the intracellular acid phosphatases(ACP) activity. In the conditions of common culture(CC),single collagen culture(SCC) and double collagen culture(DCC), with or without serum, study the maintenance of cellular function and the severity of cellular damage. RESULTS Compared with the other two methods, the LDH contents were significantly lower( P

Objective To compare the effect of propofol and Midazolam for the vein puncture and indicators of respiratory cycle in the e-mergency center. Methods According to different anaesthetic,100 patients who needed for central venepuncture in patients,were randomly divided into Propofol group (50 cases) and Midazolam group (50 cases),given different dose input,and evaluated by RSS(Ramsay Sedation Scale,RSS) . In terms of the onset time and recovery time of consciousness,the central venous puncture were performed with all the patients. Results There was no significant difference in the process of sedation effect on respiration and circulation of the patients between 2 groups. And the differences between 2 groups with the time of reaching RSS-5 were no statistical significance,while the differences of consciousness recovery time between 2 groups were statistical significance. Conclusion The appropriate dosage and velocity of Propofol and Midazolam can quickly achieve central vein puncture,with slight influence on respiratory and circulatory system and no serious adverse reaction. But the onset time and consciousness recovery time of the Propofol which has a good controllability was shorter than those of Midazolam.

Objective To study the long-term neurodevelopment in term neonates with hyperbilirubinemia and explore the predictive value of cerebrospinal fluid neuron specific enolase (CSF-NSE) on long-term neurodevelopment outcome.Methods A mental and psychomotor scale for 0-4 years old was performed to evaluate the intelligence development of 39 neonates with hyperbilirubinemia and 39 randomly selected healthy controls when they were at 3 to 24 months old. The former were tested for the level of CSF-NSE in jaundice climax.Results There was significant difference between 2 groups in total development quotient (DQ) tested at 3 month and 24 month old (P=0, 0.047). It was shown that the DQ scores for fine activity and social behavior were significantly lower in the study group than those in the control group (Pa=0). Furthermore, within the hyperbilirubinemia group, CSF-NSE was significantly associated with DQ of 3 month and 24 month old, while there was not association with TSB. The correlation coefficients were -0.46(P=0.04) and -0.32(P=0.047),respectively.Conclusions Hyperbilirubinemia may influence long-term neurodevelopment of term infants and CSF-NSE can predict this outcome.
