Objective: To analyze the mid long term results of prosthetic valves replacement. Methods: 2?141 patients underwent prosthetic valve replacement from 1978 to 2001, and 1?681 patients were followed up by completion of 78.5%, cumulate of 8?021.1 patient years and averages of 4.77 patient years each. The data were analyzed by multi factor regression and T test. Results: 92 patients died after operation. The 5 year and 10 year survival rates were (92.3?2.2)% and (90.1?2.7)%, respectively. The main complications were thromboembolism, valve mechanical malfunction, peri prosthetic leak, hemolysis and SBE. The heart function (NYHA) was significantly improved after valve replacement. Conclusion: The mid long term results of prosthetic valve replacement are rather satisfactory with low mortality and morbidity. Subvalvular structure preservation and tricuspid annuloplasty contribute can greatly improved heart function. Satisfactory myocardial protection during CPB is the key of successful operation.

BACKGROUND: The study aimed to explore the effects of hypothermia state induced by 4 oC normal saline (NS) on liver biochemistry, enzymology and morphology after restoration of spontaneous circulation (ROSC) by cardiopulmonary resuscitation (CPR) in swine. METHODS: After 4 minutes of ventricular fibrillation (VF), standard CPR was carried out. Then the survivors were divided into two groups: low temperature group and normal temperature group. The low temperature (LT) group (n=5) received continuously 4 oC NS at the speed of 1.33 mL/kg per minute for 22 minutes, then at the speed lowering to 10 mL/kg per hour. The normal temperature (NT) group (n=5) received NS with normal room temperature at the same speed of the LT group. Hemodynamic status and oxygen metabolism were monitored and the levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) were measured in blood samples obtained at baseline and at 10 minutes, 2 hours and 4 hours after ROSC. At 24 hours after ROSC, the animals were killed and the liver was removed to determine the Na+-K+-ATPase and Ca2+-ATPase enzyme activities and histological changes under a light or electron microscope. RESULTS: Core temperature was decreased in the LT group (P<0.05), while HR, MAP and CPP were not significantly decreased (P>0.05) compared with the NT group (P>0.05). The oxygen extraction ratio was lower in the LT group than in the NT group (P<0.05). The serum levels of ALT, AST and LDH increased in both groups but not significantly in the LT group. The enzyme activity of liver ATP was much higher in the LT group (Na+-K+-ATP enzyme: 8.64±3.32 U vs. 3.28±0.71 U; Ca2+-ATP enzyme: 10.92±2.12 U vs. 2.75±0.78 U, P<0.05). The LT group showed less cellular edema, inflammation and few damaged mitochondria as compared with the NT group. CONCLUSION: These data suggested that infusing 4 oC NS continuously after ROSC could quickly lower the core body temperature, while maintaining a stable hemodynamic state and balancing oxygen metabolism, which protect the liver in terms of biochemistry, enzymology and histology after CPR.

Abstract: Toxoplasma gondii, an opportunistic pathogenic protozoan, is widely distributed worldwide and can cause zoonoses, which is a serious threat to human health. Nowadays, the relationship between T. gondii infection and neuropsychiatric diseases has attracted researchers' attention increasingly. T. gondii infection is related to the pathogenesis of many neuropsychiatric diseases by affecting the nervous system, such as schizophrenia, depression, Alzheimer's disease, and so on. This review will focus on the relationship between T. gondii infection and neuropsychiatric diseases and summarizes the possible mechanisms of disorders resulting from T. gondii infection． It is expected that the study on the related pathogenic mechanism of T. gondii will lead to new therapeutic directions and feasible solution for the clinical treatment of neuropsychiatric diseases caused by T. gondii infection.

Objective To explore the etiology, clinical features and treatment of status epilepticus (SE) after orthopedic surgery and improve the diagnosis and treatment. Methods The data of 21 patients with SE after orthopedic surgery were retrospectively analyzed. Among these 21 patients, 5 with epilepsy before the orthopedic surgery, 4 with acute ischemic cerebrovascular diseases, 3 with fat embolism syndrome, 1 with tumor emboli, 4 with metabolic encephalopathy, 1 with hypoglycemia, 1 with diabetic ketoacidosis and 2 with chronic renal insufficiency were found. Orthopedic surgery was performed on these patients: fracture of the shaft of the femur was found in 8; hip arthroplasty was performed in 7 with fracture of femoral neck; fracture of the shaft of the humerus was noted in 3; giant cell tumors in the lumbar vertebra was found in 1; burst fracture in the thoracic vertebra was found in 1 and amputation was conducted in 1 with diabetic gangrene. Results Diazepam injection was employed to control the seizure in 11 patients with SE and 9 got good effect; valproate sodium injection was also used to control the seizure in 10 patients with SE and 6 showed good results. Conclusions Many reasons can result in the happening of SE after orthopedic surgery. The incidence and death rate of SE can be obviously decreased by good controlling the physical conditions in the perioperative period. The anti-epilepsy drugs should be chosen according to the age and physical conditions of the patient and the side effects of the anti-epilepsy drugs.
