[Objective] To investigate the results and to evaluate the validity of the supracondylar femoral osteotomy and internal fixation for treatment of flexion deformity of the knee joint in adult polio patients.[Methods]From April 2002 to August 2008,141 knees in 127 cases with flexion deformity of knee from poliomyelitis were treated with supracondylar femoral extension osteotomy and internal fixation.They were 14~45 years old with an average of 18.3.Of them,62 knees in 56 cases were male,79 knees in 71 cases were female.Eighty-three cases needed pressing knee on walking.Thirty-five cases walked with a crutch and 9 cases walked with two crutches.It should be treated with soft tissue release and skeletal traction before osteotomy in severe flexion deformity(over 40 degrees).All cases took weight-bearing X-ray films of lower extremities before and after operation.Angle of knee flexion,operative complications,bone healing and final function were recorded.Patients can undertake continuous passive flexion and extension motion from the 2nd day postoperatively.The knee operated was put in 10~20? flexion after operation and extended to full extension gradually in 2 weeks.[Results]All patients felt comfortable after operation and no neurovscular complications and infection happened.Follow-up time was 12-72 months with an average of 18 months.Solid bone union showed in all femoral cutting ends.No mal-union,non-union and implant failure happened.All flexion deformities of knees were corrected.The angle of flexion contracture of knee was from 36.4?(18?～61?)preoperatively to 2.8?(-5?～8?)postoperatively.The amount of correction was 18?to 56?with an average of 32.9?.One hundred and eight patients can walk stably by hinself or with brace,19 cases still need some help for walking(pressing knee in 6 case,one crutch in 10 cases and two crutches in 3 cases)at last follow-up.No ankylosis of knee joint or peroneal nerve paralysis occurred.All cases were satisfying with their range of motion of knee.[Conclusion]Supracondylar femoral osteotomy and rigid internal fixation and early rehabilitation exercise is a safe and effective strategy for the adult flexion deformity of knee joint.

The effects of cyanide poisoning on the contractibility of the cardiac muscle were observed after the dogs were infused intravenously with a lethal dose of NaCN (2.5 mg/kg) within 2 minutes through a cannulated femoral vein. Heart rate (HR) , left ventricular pressure (LVP) , the largest changing rate of LVP (LVP?dp/dtmax), cardiac muscle contractibility (CMC) , the largest changing rate of CMC (CMC?dc/dtmax) , and ECG changes were recorded. It was found that there was an initial excitatory response of cardiac functions in the first minute of NaCN infusion, and then a drastic cardiac failure occurred, which resulted in the rapid death of the dogs within 10 minutes after NaCN administration. The changes of myocardial contractibility were slower than those of .other cardiac parameters, which implies that cyanide can exert an excitation on the myocardium initially. Our results indicate that the effects of cyanide on myocardial contractibility may be one of the important factors to induce serious arrhythmia,which in turn results fatal cardiac failure.

Abstract To analyse the mechanism of TECA bio-artificial liver support system(BALSS)to treat acute liver failure (ALF) canines. The blood of partial liver resection-induced ALF canines or RPMI1640 solution were circulated in the inner space of the hollow fibers (blood loop), and porcine hepatocytes were cultured in outer space of the hollow fibers (cell loop). The concentrations of lidocaine, albumine and urine in the RPMI1640 solution were measured. The compositions of proteins in cell loop and blood loop were analysed by polyacrylamide gel electrophoresis (PAGE). The ultrastructure of porcine hepatocytes in BALSS was observed with transmission electronic microscopy. There were not any proteins in RPMI1640 solution before BALSS circulation. After 6 hours of the BALSS circulation, the concentration of lidocaine in RPMI1640 solution decreased significantly,and concentration of albumine and urine nitrogen increased gradually. The ultrastructure of the porcine hepatocyte shown damaged after BALSS 6h. The results suggested that TECA BALSS could replace temporarily the functions of failure liver by the effects of biologic transform and synthesis of porcine hepatocytes.

Objective To assess the efficacy and safety of BioLiver Ⅰ bioartificial liver support system (BALSS) on the treatment of two types of acute liver failure (ALF) canine models. Methods The drug induced ALF canine model was established by multiple subcutaneous injections of acetaminophen. Another model was operated to resect 80 percent of the liver tissue. The primary hepatocytes were separated from the swine and cultured within the BALSS. The ALF models were treated by BioLiver ⅠBALSS for 6 hours. The changes of physiological, biochemical and histological parameters were observed before and after the treatment. Results The canines developed ALF 48 hours after injections of acetaminophen, the established rate of the model was 63 3%. While the other ALF canine model developed 24 hours after 80 percent liver resection and the established rate was 84 2%. Using our modified enzymatic digestion method, the yield of hepatocytes was (1 0～3 0)?10 10 per swine with high viability. BioLiver ⅠBALSS treatment resulted in beneficial effects on blood biochemical parameters. The pathological lesions of the liver were repaired. BALSS treatment was harmless to other organs. The ALF canines in drug group survived longer than in operation group. Conclusion This type of BALSS can provide safe and efficacious liver function support in the two types of ALF canine models, and it may be as an hepaful and important therapy to ALF

This study was aimed to establish an Ultra Fast Liquid Chromatography-Photo Diode Array (UFLC-PDA) method for the simultaneous determination of five chemical components, which included chlorogenic acid, loganin, sweroside, evodia rutaecarpa glycosides and triplostoside A, in Pterocephalus hookeri h eck.
