Acute kidney injury(AKI) can lead to remote organ damage.The specific mechanism by which the AKI results in distant organ damage is yet to be determined.In animal models,it has become increasingly clear that AKI is not an isolated event but results in remote organ dysfunction involving the heart,lungs,liver,and brain.This review summarizes the effects of AKI on remote organs.

The zymograms of lactate dehydrogenase (LDH) and esterase (EST) isoenzymes in different physiologic state from two species of Anopheles mosquitoes were studied with polyacrylamide gel electro -phoresis. Some zymogram variation of LDH from single female mosquito was found after engorged blood meals for 48 h, that consisted of two main bands whose relative mobility (Rm) was different. The isozymograms of EST showed some similar characteristics of sibling which divided into three groups ESTⅠ, ESTⅡand ESTⅢ, respectively. The two species of mosquitoes could be differentiated from each other by the particular band in EST Ⅱ group of An. anthropophagus.

A simple and reliable procedure for the isolation of pure DNA from human fetal liver is described.A high pure and natural DNA with an average molecular weight of 4 ?106 can be easily obtained after the sample is treated with SDS and trypsin and fractionated by a sepharose 4B column.The product meets the requirement for general research work of molecular biology.

This paper is to report the results of the clinical application of the Shexiang hemostasis-removing plaster. 265 cases of dermatohemostasis including chilblain, erythema multiforme, erythema nodosum, and so on were treated locally with Shexiang hemostasis-removing plaster. 20 cases of dermatohemostasis were treated with Shexiang analgesic plaster and served as control.It was found the rates of marked improvement and improvement after the application of Shexiang hemostasis-removing plaster were 85.61% and 96.60%, while those after Shxiang analgesic plaster treatment were 65% and 90% respectively. It is bovious that Shexiang hemostasis-removing plaster is more effective in treating dermatohemostasis than Shexiang analgesic plaster. The difference between the 2 is statistically significant(P

Coronal restoration of endodontically treated teeth may be viewed as one of the main parameters that influence the outcome of endodontic treatment. The purposes of restoring endodontically-treated teeth include preventing recontamination of the root canal system and periapical area, replacing the compromised dental hard tissue, restoring the coronal morphology and function, providing necessary strength for the restoration/tooth complex for functional stress, and avoiding crown and/or root fracture. This article reviewed recent researches on the restoration of endodontically treated teeth, provided evidence for clinical practice on topics as when to restore them, basic principles to be considered during treatment planning, and specific restoration options for both anterior and posterior teeth under different functional occulsal load conditions. Several issues should be taken into account during the decision making process, such as remaining tooth tissue, functional masticatory forces, comprehensive oral rehabilitation, and esthetic requirements.

Zebrafish has unique advantages over other animal models in the aspect of drug screens for active ingredients and gains more and more attentions in drug research and development recently. Thus, this article reviews the recent advance of zebrafish-based drug screens in Chinese traditional medicine (TCM) effective part research, monomer drug screening, activity evaluation of natural products, discovery of new uses for old drugs, and toxicity assessment in early-phase drug discovery.

Objective To investigate the the effect and interaction of morphine dependence model and naloxone doses on withdrawal intensity. Methods To observe the withdrawal signs and weight loss in two kinds of morphine dependent rats after the precipitating by naloxone of different doses an devaluate the withdrawal intensity.Results Morphine dependence were successfully induced in two ways.There was no significant difference of withdrawal intensity in five-day model(total morphine dose 380mg.kg－1) after precipitating by naloxone of 2mg.kg－1 and 4mg.kg－1（P＞0.05）. Withdrawal intensity of twelve-day model(total morphine dose 1365mg.kg－1)increased significantly with the increase of naloxone dose（P＜0.01）,but it was more intensive significantly than five-day model only after 4mg.kg－1 dose of naloxone. Conclusion Appropriate method should be used to induce morphine dependence and these experimental factors should be combined in assessment of withdrawal intensity.

BACKGROUND:Maxilary posterior tooth defects can be repaired using the dental implant. However, implantation accuracy is not ensured by traditional plaster models used as implant template, which leads to the incidence of complications,andaffectsthe repair effects.
OBJECTIVE:To study application effects of surgical guide plates designed using the computer aided design (CAD)/computer aided manufacturing (CAM) technology for the repair of maxilary posterior tooth defects.
METHODS:Implant treatment was performed in 30 patients with maxilary posterior tooth defects. Surgical guide plate was made using the CAD/CAM technology after CT scan of the jaw bone. The repair was conducted with guideplateassistant. The deviation between the virtual and actual implant position was measured after implantation. The clinical repair effects and periodontal tissues were observed during the 12-month folow-up.
RESULTS AND CONCLUSION:Thirty-sixCAD/CAM surgical guide plates in 30 patients werestabilized after implantation. Thirty-six implants were emplaced precisely with the assist of the surgical guide plates. There was no any problem during the process of implantation. The deviation of the head between the virtual and actual implant position was very smal, which did not affect the accuracy of implant placement. Before and 6 and 12 months after the repair, gingival crevicular fluid, tumor necrosis factor-α, and sulcus bleeding index were not obviously changed in the patients. Our results suggest that the implant head deviation and angle deviation appearduring the repair process of maxilary posterior tooth defects using CAD/CAM surgical guide for dental implants;however, the implantation accuracy is not affected. The repair effect is ideal and periodontal tissue is in good status after implantation.

BACKGROUND:Targis/composite fiber is a new type of non-metalic repair material that has good hardness and strength, but it is rarely reported on its application in the repair of young permanent tooth defects.
OBJECTIVE:To investigate the clinical effect of Targis/composite fiber in repairing young permanent tooth defects.
METHODS:Sixty cases of young permanent teeth defects 10-17 years of age were enroled, including 27 males and 33 females. Al cases were subjected to Targis/composite fiber repairing. After 36 months of folow-up, alkaline phosphatase level, probing depth, gingival sulcus bleeding index, tooth mobility, plaque index, gingival crevicular fluid volume and aspartate aminotransferase level in patients were detected; the integrity and edge of dental prosthesis and the color matching.
RESULTS AND CONCLUSION:After 36 months, the alkaline phosphatase level in the patients had no significant changes (P> 0.05), but the probing depth, gingival sulcus bleeding index, tooth mobility, plaque index, gingival crevicular fluid volume and aspartate aminot ransferase level were decreased significantly compared with those before repair (P< 0.05). Additionaly, there were two cases of incomplete dental prosthesis, six of color mismatching, andtwo of unsealed prosthesis edge. These findings indicate that the Targis/composite fiber for repairing young permanent tooth defects has good histocom patibility maintains periodontal health in good condition, is a kind of ideal repair materials.
