BACKGROUND:Acute liver failure is still a life-threaten- ing disease although it can be treated by liver transplanta- tion. This study was conducted to assess the molecular ad- sorbent recycling system (MARS), which may bridge acute liver failure patients to liver transplantation. METHODS: Biochemical indexes and other clinical data were analyzed of 8 patients with acute liver failure, who had been treated by MARS for 34 times and subsequent Piggyback liver transplantation. RESULTS: After treatment with MARS, the levels of tran- saminase and total bilirubin decreased markedly, but coagu- lation function remained unimproved. All patients survived and discharged from the hospital. CONCLUSION: MARS is effective in bridging patients with acute liver failure to liver transplantation.

BACKGROUND: Appropriate animal models are impor- tant for studying acute liver failure. This study was to assess a new suitable rat model for acute liver failure. METHODS: After the right influent hepatic vessels were clamped for a period of time (45, 60 or 90 minutes respec- tively), the animal model was established by removal of the clamp for restoring blood flow of the right lobes while im- mediately removal of the median, left lateral and caudate lobes. Animal survival rate was observed in the following 14 days in each group. To study the pathophysiological chan- ges of the model, some biochemical parameters in 5 con- secutive days were evaluated in the 60-minute group. Inter- nal bioartificial liver was transplanted in the peritoneal cavi- ty to test the reversibility of the model. RESULTS: The survival rate of the models decreased, as the ischemia time of the right lobes prolonged to zero in the 90-minute group, to 50% in the 60-minute group and to 100% in the 45-minute group on the fifth day after opera- tion. The levels of ammonia, alanine aminotransferase, al- kaline phosphatase, total bilirubin and prothrombin were elevated dramatically 12 to 24 hours after operation in the 60-minute group. When internal bioartificial liver was transplanted, the survival rate increased significantly in ad- dition to the levels of ammonia and total bilirubin. CONCLUSION: A period time of ischemic injury in the right lobe followed by 70% liver resection can produce a graded acute hepatic failure model in rats.

From the point of view that people have to obey the river's geo-attributes in the river regulation, the definition and the meaning of the geo-attributes of a river are discussed. The geo-basis of the river regulation of the middle reaches of the Yangtze River is expounded in five aspects, including the structural geomorphology environment of flood storage and discharge, the distribution characteristics of subsidence and the sedimentation areas of Dongting Basin, the history evolution of Jianghan Basin, the function of Jianghan Basin and Dongting Basin as the flood water detention areas of Jingjiang River reach in ancient time, and the geological characteristic of Jingjiang River reach. Based on the geo-attributes of the middle reaches of the Yangtze River, some ideas about the middle reach regulation of the Yangtze River are put forward: to process the interchange between the lakes and diked marsh areas in Dongting Basin, to canal the new river route as the flood diversion channel of Jingjiang River reach with the paleo river, to recover the function of Jianghan Basin as flood detention area of the middle reaches. And we should take into consideration the geo-environment of the whole Yangtze River in the river regulation of middle reaches.

Reactive oxygen species （ROS） can be produced by interactions between sunlight and light-absorbing substances in natural water environment. ROS may participate in the indirect photolysis of trace organic pollutants, therefore resulting in changes in their environmental fates and ecological risks in natural water systems. Bisphenol A （BPA）, an endocrine-disrupting chemical, exits widely in natural waters. The photodegradation of BPA promoted by ROS （-OH, 1O2, HO2./O2^-）, which were produced on the excitation of ubiquitous constituents （such as nitrate ion, humic substances and Fe（Ⅲ）-oxalate complexes） in natural water under simulated solar radiation was investigated. Both molecular probe method and electron spin resonance （ESR） test were used for the characterization of the generated ROS. It was found that .OH was photochemically produced in the presence of nitrate ions, humic substances and Fe（Ⅲ）-oxalate complexes and that 102 was produced with the presence of humic substances. The steady-state concentrations of .OH was 1.27×10^-14 mol/L in a nitrate solution, and the second-order rate constant of BPA with ＂OH was 1.01×10^10 L/（mol.s）.

The theoretical evaluating method is given for the drawability of the sheet with normal anisotropy. The general solution on the cracking load of deep-drawing is deduced, which is based on three kinds of hardening curve of materials most in use. The distributions of stress and strain in the deformed region and the drawing force are obtained by the numerical method. The limiting drawing ratio is calculated through computer-aided simulating test. The experiments of deep-drawing to four kinds of sheet metals express that the relative errors between the predictive and the experimental results about the cracking load and the limiting drawing ratio are within 5%. The drawability of common sheet metals can be quantitatively evaluated in precise terms by means of the theory and the method advanced in this paper.

It is well known that the right global dimension of a ring R is usually computed by the right derived functors of Hom and the left projective resolutions of right R-modules. In this paper, for a left coherent and right perfect ring R, we characterize the right global dimension of R, from another point of view, using the left derived functors of Hom and the right projective resolutions of right R-modules. It is shown that rD(R) ? n (n ? 2) if and only if the gl right Proj-dim M R ? n?2 if and only if Ext n?1(N,M) = 0 for all right R-modules N and M if and only if every (n?2)th Projcosyzygy of a right R-module has a projective envelope with the unique mapping property. It is also proved that rD(R) ? n (n ? 1) if and only if every (n?1)th Proj-cosyzygy of a right R-module has an epic projective envelope if and only if every nth Proj-cosyzygy of a right R-module is projective. As corollaries, the right hereditary rings and the rings R with rD(R) ? 2 are characterized.

In a previous paper, we proposed another special critical value concerning the evolution of the long period family around the equilateral equilibrium points, besides the two values given by Henrard. Are there any other special critical values？ After studying the stability curves of the long period family carefully, we gave a negative answer. During the study, we found an interesting family of periodic orbits which we called the homo family. We studied the evolution of this family following the increase of μ. With these findings, we were able to explain the origin of the four branches of periodic families emanating from L4 and the stability results of the equilateral equilibrium points.
