| 1 | A novel inexpensive conductive material:Er-modified maifanite by gaseous penetration technology显示文摘Aiming to solve the problem of corrosion and high cost of the conductive fillers, the powders with the properties of anti-oxidation, corrosion resistance and thermal stability should be developed. A new modification technology, rare earth gaseous penetration, was applied to enhance the conductivity of maifanite in this paper, and the mechanism for improving the conductivity of maifanite effectively was speculated in detail for the variations of the composition, structure and morphology between the original and Er-penetration maifanite powders. The results of the resistivity show that Er-penetration can really improve the conductivity of maifanite powders. When the penetration temperature is 500 ℃, the resistivity of maifanite surprisingly declines to 93.2 Ω·m. Moreover, XRD and XPS patterns display that the cations in maifanite are substituted by Er^(3+) successfully, resulting in the production of electrons in the system, which is the key reason to heighten the conductivity of maifanite. Most importantly, Erpenetration maifanite, whose price is really low, can replace the expensive conductive powders and be used in the electronic industry to decrease the cost of the electronic devices. | Liying Qi Sue Hao Suisheng Li Tiancheng Sun Xinrong Liu | 2019 | Journal of Rare Earths2019，37，3： | 2 |

| 3 | N-methyl-D-aspartate receptor subunit 1 protein expression in the hippocampus and temporal cortex of kainic acid-induced epilepsy rats显示文摘BACKGROUND:The N-methyl-D-aspartate receptor subunit 1 (NMDAR1) contributes to the incidence of epilepsy.However, the relationship between epilepsy-induced brain injury and NMDAR1 remains poorly understood.OBJECTIVE:To investigate changes in NMDAR1 protein expression in the hippocampus and temporal cortex of kainic acid-induced epilepsy rats.DESIGN, TIME AND SETTING:A randomized, controlled, animal experiment was performed at the Department of Physiology and Department of Pathology, Basic Medical College of Jilin University from March 2002 to March 2003.MATERIALS:Rabbit anti-NMDAR1 antibody was purchased from Wuhan Boster Biological Technology, China.METHODS:A total of 80 healthy, male, Wistar rats, aged 22 weeks, were randomly assigned to sham-surgery (n=10) and model (n=70) groups.Epilepsy models were established by injecting kainic acid (1 μL) into the right amygdala, and rats were sacrificed at 2, 6, 24, 72 hours, and 7, 15, 30 days after surgery, with 10 animals at each time point.The rats in the sham-surgery group were injected with 1 μL phosphate buffered saline into the right amygdala.MAIN OUTCOME MEASURES:NMDAR1 protein expression in the hippocampus and temporal cortex at 2, 6, 24, 72 hours and 7, 15, 30 days after epilepsy was detected using immunohisto-chemistry and flow cytometry analysis.RESULTS:In the sham-surgery group, a few NMDAR1-positive cells were distributed in the hippocampus and temporal cortex.In the model group, NMDAR1-positive cells were increased in the hippocampus and temporal cortex at 2 hours following kainic acid-induced epilepsy.They were significantly increased at 6 hours, and slightly decreased at 7 days (CA3 region and temporal cortex), but remained greater than the sham-surgery group.This continued until day 30 (P<0.01).In addition, there were more NMDAR1 positive cells in the hippocampal CA3 and dentate gyrus than the temporal cortex (P<0.01).CONCLUSION:In epilepsy model rats, NMDAR1 protein expression was upregulated in the hippocampus and temporal cortex, and in particular in the hippocampal CA3 and dentate gyrus.NMDAR1 may participate in epilepsy and the excitation process of the epileptic brain. | Zan Wang Hongyu Jiang Suisheng Wu Hongmei Meng Li Ji Li Cui Weihong Lin | 2010 | Neural Regeneration Research2010，5，14： | 0 |
| 4 | PBLT AND THE CONCERNED PROBLEMS (WITH A REPORT OF 48 CASES)显示文摘Objective:To study the new surgical technique by piggyback of liver transplantation(PBLT) used to treat end-stage liver disease.Methods:Forty-eight cases of PBLT have been performed by author in 45 patients from September, 1995 to December,2000. The piggyback procedure was used in all cases, which included 4 retransplantation and 3 combined kidney-liver transplantation(CKLT), 3 Orthotopic inferior vena cava(IVC)-bridge-atrium LT and 1 paraorthotopic IVC-bridge to atrium LT, 1 auxiliary combined hepatovenal transplantation(ACHRT), and 1 auxiliary combined hepatointestinal transplantation (ACHIT).Result:All performances were successful and no technique-related complications occurred. The longest survival of liver malignancy that had PBLT was 1 year and 4 months, and the other 2 patients of benign end-stage liver disease who had PBLT have survived 4 years and 10 months and 5 years and 6 months respectively with a life of good quality. The survival rate of the benign end-stage liver disease that had PBLT since the end of 1998 is 67%. The 2 cases who had CKLT and 1 case ACHRT had been living more than 1 year and 2 year six months.Conclusion:As the new technique being used since the end of 1980s, the PBLT procedure is better than the classical one because no veno-venous bypass is needed and the hemodynamics are stable. The difficulty with the procedure is the removal of the patient’s liver, a series of ameliorations have been done, which include auxiliary LT technique and second PBLT technique. | Ye Qifa, Xia Suisheng,Ling Zhengbin,Gong Nianqiao,Ming Yingzi,Li Gangshan Institute of Organ Transplantation, Tongji Hospital of Huazhong Science and Technology University,Wuhan 430030 | 2002 | 中国现代医学杂志2002，12，12： | 0 |
