| 1 | Safe time to warm ischemia and posttransplant survival of liver graft from non-heart-beating donors显示文摘AIM: To explore the dynamical changes of histology, histochemistry, energy metabolism, liver microcirculation, liver function and posttransplant survival of liver graft in rats under different warm ischemia times (WIT) and predict the maximum limitation of liver graft to warm ischemia. METHODS: According to WIT, the rats were randomized into 7 groups, with WIT of 0, 10, 15, 20, 30, 45, 60min, respectively. The recovery changes of above-mentioned indices were observed or measured after liver transplantation. The graft survival and postoperative complications in each subgroup were analyzed.RESULTS: Liver graft injury was reversible and gradually resumed normal structure and function after reperfusion when WIT was less than 30 rain. In terms of graft survival, there was no significant difference between subgroups within 30 rain WIT. When WIT was prolonged to 45 rain, the recipients' long-term survival was severely insulted, and both function and histological structure of liver graft developed irreversible damage when WIT was prolongedto 60 rain. CONCLUSION: The present study indicates that rat liver graft can be safely subjected to warm ischemia within 30 min. The levels of ATP, energy charge, activities of glycogen, enzyme-histochemistry of liver graft and its recovery potency after reperfusion may serve as the important criteria to evaluate the quality of liver graft. | Xiao-ShunHe YiMa Lin-WeiWu Wei-QiangJu Jin-LangWu Rui-DeHu Gui-HuaChen Jie-FuHuang | 2004 | World Journal of Gastroenterology2004，10，21： | 13 |

| 3 | Dynamical changing patterns of glycogen and enzyme histochemical activities in rat liver graft undergoing warm ischemia injury显示文摘AIM: To investigate the changing patterns of glycogen and enzyme histochemical activities in rat liver graft under a dif ferent warm ischemia time (WIT) and to predict the tolerant time limitation of the liver graft to warm ischemia injury.METHODS: The rats were randomized into five groups, WTT was 0, 15, 30, 45, 60 min, respectively, and histochemical staining of liver graft specimens was observed. The recovery changes of glycogen and enzyme histochemistry activities were measured respectively 6 and 24 h following liver graft implantation.RESULTS: The activities of succinic dehydrogenase, cytochrome oxidase, apyrase (Mg++-ATPase) and content of glycogen were decreased gradually after different WIT in a time-dependent manner. The changes were significant when WIT was over 30 min.CONCLUSION: Hepatic injury is reversible within 30 min of warm ischemia injury. Glycogen and enzyme histochemistry activities of liver grafts and their recovery potency after reperfusion may serve as criteria to evaluate the quality of liver grafts. | Xiao-ShunHe YiMa Lin-WeiWu Jin-LangWu Rui-DeHu Gui-HuaChen Jie-FuHuang | 2005 | World Journal of Gastroenterology2005，11，17： | 5 |
| 4 | 3,4-oxo-isopropylidene-shikimic acid inhibits adhesion of polymorphonuclear leukocyte to TNF-α-induced endothelial cells in υitro显示文摘AIM: To examine the effect of 3,4-oxo-isopropylidene-shikimic acid (ISA) on human polymorphonuclear leuko- cyte (PMN) adhesion to human umbilical vein endothelial cells (HUVEC) and explore its mechanism. METHODS: Adhesion of PMN to HUVEC was measured by rose bengal staining assay. Cell-ELISA and RT-PCR methods were used to examine the expression of adhesion molecules ICAM-1. Cell viability was detected with MTT assay. RESULTS: ISA (1-100 μmol/L) effectively reduced PMN adhesion to TNF-α-induced HUVEC with the inhibitory rate from 17.2 % to 53.5 %, and exerted no effect on PMN adhesion to normal HUVEC. Adhesion molecule ICAM-1 surface protein and mRNA expression induced by TNF-α (400 kU/L) were significantly inhibited by ISA. In addition, the cell viability of HUVEC was unchanged 48 h after treatment with ISA. CONCLUSION: ISA inhibited TNF-α-stimulated PMN-HUVEC adhesion and expression of ICAM-1. | YiMA Jian-ningSUN Qiu-pingXU Zi-liYOU Ya-jianGUO | 2004 | Acta Pharmacologica Sinica2004，25，2： | 3 |

| 16 | β_2-ADRENERGIC RECEPTOR GENE POLYMORPHISM IN CHINESE NORTHERN ASTHMATICS显示文摘To investigate whether the polymorphisms of β2-adrenergic receptor (β2-AR) at position 16, 27, 164 are asso-ciated with asthma in Northern Chinese subjects. Methods Genomic DNA was collected from unrelated Northern Chinese population of Han ethnicity, including 125 un-related asthmatic individuals and 96 healthy controls. β2-AR genes at position 16, 27, 164 were amplified by using restriction fragment length polymorphism (RFLP) and allelic specific polymerase chain reaction methods. All asthmatics had their serum IgE (total and specific) antibody or skin-prick test measured, bronchial reactivity to methacholine (Mch) and bronchial rever-sibility by β2-agonist evaluated. Results (1) The frequency of Gly 16 homozygous was significantly higher in the asthmatic group than that in healthy controls (22.4% vs. 8.3%, P < 0.05), OR was 2.9 with 95% CI 1.26-6.78. The proportion of Gly 16 allele was also higher in asthmatics than that in control (0.46 vs. 0.36, P < 0.05); Gly16 homozygous was not independently associated with asthma pathogenesis (P = 0.21, OR 0.42 with 95% CI 0.11-1.61). (2) Of 51 night attack patients, 18 carrying Gly16 homozygosity, if compared with 10 of 74 nonnocturnal asthmatics carrying this genotype, there was significant difference between these two groups (35.3% vs. 13.5%, P < 0.01). (3) The average dose of PD20-Mch was significantly lower in patients carrying Gln 27 homozygous than those carrying homozygous Glu 27 and Gln/Glu 27 heterozygous (0.2 ± 0.3, 1.6 ± 0.8, and 2.1 ± 3.0 μmol/L,P < 0.05). Conclusion β2-AR gene polymorphisms might confer susceptibility to asthma in Chinese Northern patients. β2-AR gene, coordinated with other candidate loci, plays a role in the development of asthma. | Jin-mingGao Yao-guangLin Chang-chunQiu Yi-wenLiu YiMa YingLiu | 2004 | Chinese Medical Sciences Journal2004，19，3： | 0 |
| 17 | Experimental Investigation of Wave Heights in A Directional Wave Field Through Image Sequences显示文摘Measurements of wave heights with image sequences from a Charged Coupled Device(CCD) camera were made. Sinusoidal, as well as unidirectional and directional, waves were used for the experiments. A transfer function was obtained by calibration of the magnitudes of the gray values of the images against the results of wave gauge measurements for directional waves. With this transfer function, wave heights for regular waves were deduced. It is shown that the average relative errors are smaller than 16% for both unidirectional and directional waves. | Chung-Ren CHOU Teng-Wei LIN Ruey-Syan SHIH John Z.
