ObjectiveTo investigate the effect of immunoglobulin G (IgG) extravasated from blood circulation on the expression of toll-like receptor 4 (TLR4) induced by peripheral lipopolysaccharide (LPS) in rat brain. Methods The rats were divided into four groups in random, 5 rats in each. Group one received LPS 100μg/kg by intraperitoneal administration, normal saline was given by intravenous injection 6 hours later; group two was injected with adrenalin (AD) 15μg/kg intravenously; group three was treated with LPS intraperitoneally, AD was injected 6 hours later; group four was injected normal saline intravenously as control. For all groups, the animals were sacrificed 30 min after the last injection, and the brains were taken for investigation of the TLR4 expressions by immunofluorescence staining and RT-PCR. Result Immunofluorescence staining showed that IgG immunoreactive product was patch-like, distributed in the brain parenchyma in all the animals that received AD. In the LPS+normal saline group, IgG was found merely around the blood vessels. Meanwhile, in LPS+AD animals, TLR4 immunoreactive product coexisted with microglia marker Iba-1 within the IgG extravasated area. The double-labeled cells dispersed in the brain parenchyma and near to the cerebral vessels. In the LPS+saline group, TLR4 positive cells were endothelial-like. RT-PCR results indicated that the expression level of TLR4 in the LPS+AD group were significantly higher than that in the LPS+saline group or AD group or the saline control (P<0.01). Conclusion Extravasated circulating IgG may enhance the TLR4 expression in the rat brain induced by peripheral LPS.

OBJECTIVE: To analyze the research literatures related to bioartificial liver, and to make a conclusion concerning the development of bio-artificial liver.DATA SOURCES: Using bioartificial liver, liver cell, hepatocyte culture and bioreactor as search terms, searching Ovid, Springer Link database, and China National Knowledge Infrastructure, Vip Information database and Wanfang Date (1990.09-2008.09). Literatures search was limited to English and Chinese languages.DATA SELECTION: Researches regarding liver cells of bioartificial liver, reactors and auxiliary equipment was included, and the studies about immune and animal infection studies of bioartificial liver were excluded.MAIN OUTCOME MEASURES: ①The source, quantity and culturing of bio-artificial liver hepatocytes. ②Bioreactor type, nature and type of films. ③Composition of oxygen and temperature control devices of bioartificial liver.RESULTS: Totally 3898 documents seized initially in the searching by computer, according to inclusion and exclusion criteria, 29 were analyzed. Bioartificial liver was a hybrid device in which can culture hepatocytes in vitro, when the patient's blood flows through the device, material exchange with the cultured hepatocytes through semi-permeable membrane or direct contacting can take place, which can perform the same roles of detoxification, synthesis, biological transformation and other functions as real liver cells, so as to achieve the purpose of support and treatment. Bioartificial liver can also be involved in metabolism of the three major nutritive substances, as well as secretion of hepatocyte growth promo ting substances. So it is an effective alternative to the real liver as the function of detoxification and synthesis, and can fills the essential gap between the transplantation and acute liver failure.CONCLUSION: Although the bioartificial liver research has made significant progress, it still faces the problems such as limited liver cells sources, long-term maintenance of liver cell activity and function, and further optimization of the reactor design.

OBJECTIVETo investigate the protect effects of sodium ferulate (SF) on the daunormbicin(DNR-induced cardiotoxicity in juvenile rats.

METHODSForty male juvenile SD rats were randomly divided into control group (Control), daunorubicin group (DNR), sodium ferudate treatment group (DNR + SF), sodium ferudate group (SF) (n = 10) . Juvenile rats were intraperitoneally treated with DNR (2.5 mg/kg every week for a cumulative dose of 10 mg/kg) preparation immature myocardial injury model in presence with SF (60 mg/kg) oral treat- ment for 25 days. The left ventricular pressure and its response to isoproterenol were measured using left ventricular catheter. Rat myocardium myocardial pathology specimens and ultrastructure changes were also observed. The expression of cardiac Troponin I (cTNI) was detected by Western blot and RT-PCR. Results: SF treatment could inhibit the decreasing of heart rates induced by DNR damage (P < 0.05); it could increase the left ventrivular end diastolic pressure(LVEDP), heart rate, the maximal left ventrivular systolic speed(LVP + dp/dtmax) and the maximal left ventrivular diastolic speed (LVP-dp/dtmax) responding to isoproterenol stimulation(P < 0.01); SF also could improve the myocardial ultrastructure injuries and inhibit the decreasing of cTNI expression caused by DNR damages (P < 0.05).

CONCLUSIONSF treatment could alleviate the decreasing of cardiac reservation induced by DNR damages in juvenile rats, which might be related to its reversing the effects on the cardiac systolic and diastolic function injuries and its inhibiting effects on the decreasing of cTNI expression caused by DNR. The mechanism of SF preventing daunorubicin-induced cardiotoxicity in juvenile rats is relevant to inhabited cardiac Troponin I expression.
