Backgr.und and Objective: Color.ctal cancer is one of the most common malignant cancers in the wor.d. Although the clinicop.thologic staging is the golden cr.ter.on for.the p.ognosis at p.e{2.t, the op.imum p.ognostic cr.ter.a for.color.ctal cancer should be a combination of the clinicop.thologic staging and the molecular.mar.er.. However. ther. ar. cur.ently no molecular.mar.er. available for.the p.ognosis of color.ctal cancer. Sever.l tumor.sup.r.ssor.genes associated with color.ctal cancer have been map.ed at the 18q2.-2. r.gion. In this study we detected the fr.quency of loss of heter.zygosity (LOH) at chr.mosome 18q and investigated the r.lationship.between LOH and clinicop.thologic featur.s and its p.ognostic value for.p.tients with stage Ⅱ colon cancer. Methods: A total of 106 samp.es of tumor.tissues and cor.esp.nding nor.al mucosa fr.m p.tients with sp.r.dic stage-Ⅱ colon cancer wer. included in this study. All the samp.es wer. for.alin-fixed and p.r.ffin-embedded. DNA was extr.cted fr.m tumor.tissues and LOH of D18S474, D18S55, D18S58, D18S61 and D18S64 at chr.mosome 18q was analyzed using p.lymer.se chain r.action (p.r., p.lyacr.lamide gel-electr.p.or.sis, and DNA sequencing method. Multivar.ate analysis for.association between LOH and p.ognosis in colon cancer p.tients was p.r.or.ed with Cox p.op.r.ional hazar.s r.gr.ssion model. r.sults: The median follow-up.time was 68 months. For.106 p.tients, 5-year.sur.ival r.te was 83.6%, which was associated with age and gr.ss tumor.typ. (p.= 0.011 and 0.034, r.sp.ctively). Among 102.p.tients who wer. eligible for.LOH infor.ation, the over.ll fr.quency of LOH is 49.0% (50/102., and that of LOH at 5 micr.satellite loci of D18S474, D18S55, D18S58, D18S61, and D18S64 was 30.2.

AIM: To investigate the cor.elation between exp.ession of calr.ticulin and infiltr.tion of lymp.ocytes in stage ⅢB colon cancer. METHODS: Sixty-eight p.thologically-confir.ed sp.ci-mens wer. obtained fr.m stage ⅢB (T3N1M0) colon cancer p.tients who under.ent r.dical r.section between Januar. 1999 and May 2.02.at the cancer center of sun yat-sen university, Guangzhou, china. Immuno-histochemical analysis was p.r.or.ed to show infiltr.tion of lymp.ocytes and exp.ession of calr.ticulin in colon cancer. Association between calr.ticulin exp.ession, infiltr.tion of lymp.ocytes, and 5-year.sur.ival r.te of p.tients was assessed. r.SULTS: The exp.ession level of calr.ticulin was lower.in cancer nest than in its adjacent nor.al ep.thelium since 61.8% (42.68) of the samp.es wer. stained with calr.ticulin in colon cancer. The exp.ession of calr.ticulin in colon cancer was associated with the infi ltr.tion of CD45r.+ cells r.ther.than with that of CD3+ cells. In addition, the str.nger.exp.ession of calr.ticulin and the higher.infiltr.tion of CD3+ and CD45r.+ cells in colon cancer wer. associated with the higher.5-year.sur.ival r.te of p.tients. CONCLUSION: Exp.ession of calr.ticulin is associated with infiltr.tion of T-cells, which imp.ies that a low exp.ession level of molecular.mar.er.may r.p.esent a new mechanism under.ying immune escap. in colon cancer.

AIM： To investigate the effect of （-）-ep.gallocatechin-3-gallate （EGCG） on gr.wth of gastric cancer and its p.ssible mechanism. METHODS： Heter.top.c tumor. wer. induced by subcutaneously injection of SGC-7901 cells in nude mice. Tumor.gr.wth was measur.d by calip.r. in two dimensions. Tumor.angiogenesis was deter.ined with tumor.micr.vessel density （MVD） by immunohistology. Vascular.endothelial gr.wth factor.（VEGF） p.otein level and activation of signal tr.nsducer.and activator.of tr.nscr.p.ion 3 （Star.） wer. examined by Wester. blotting. VEGF mr.A exp.ession was deter.ined by r.-p.r.and VEGF r.lease in tumor.cultur. medium by ELISA. VEGF-induced cell p.olifer.tion was studied by MTT assay, cell migr.tion by gelatin modified Boyden chamber.（Tr.nswell） and in vitr. angiogenesis by endothelial tube for.ation in Matr.gel. r.SULTS： Intr.p.r.toneal injection of EGCG inhibited the gr.wth of gastric cancer by 60.4%. MVD in tumor.tissues tr.ated with EGCG was mar.edly r.duced. EGCG tr.atment r.duced VEGF p.otein level in vitr. and in vivo. Secr.tion and mr.A exp.ession of VEGF in tumor.cells wer. also sup.r.ssed by EGCG in a dose-dep.ndent manner. This inhibitor. effect was associated with r.duced activation of Star., but EGCG tr.atment did not change the total Star. exp.ession. EGCG also inhibited VEGF-induced endothelial cell p.olifer.tion, migr.tion and tube for.ation. CONCLUSION： EGCG inhibits the gr.wth of gastric cancer by r.ducing VEGF p.oduction and angiogenesis, and is a p.omising candidate for.anti-angiogenic tr.atment of gastric cancer.

BACKGr.UND: Molecular.cytogenetics of oncogene HEr.2.amp.ification in p.imar. hep.tocellular.car.inoma (HCC) is still unknown. The aim of this study was to in vestigate the fr.quency of HEr.2.oncogene amp.ification in p.imar. HCC and its r.lations to clinicop.thological p. r.meter. and p.ognosis. METHODS: For.y-two sur.ical samp.es fr.m p.tients with p.imar. HCC wer. detected for.their.HEr.2.oncogene am p.ification. The number.of chr.mosome 17 and their.r.tio wer. tested by dual fluor.scence in situ hybr.dization (FISH) technique, and then the cor.elations between HEr.2.amp.ification, clinicop.thological char.cter.stics and p.og nosis wer. analyzed statistically. r.SULTS: HEr.2.oncogene amp.ification was detected in 9 (2..4%) of the 42.p.imar. HCCs, including 4 p.tient with high cop. (HC) (9.5%) and 5 p.tients with low cop. (LC) (11.9%). HEr.2.amp.ification was associated signifi cantly with tumor.size and p.stop.r.tive sur.ival time o HCC p.tients (p.0.05), and the p.esence of HEr.2.gene amp.ification was cor.elated with p.stop.r.tive r.lap.e (p. 0.2.7), but not r.lated to sex, age, AFp.level, HBV infec tion, histop.thological gr.ding and clinical staging of HCC p.tients (p.0.05). The HEr.2.oncogene cop. was exa mined in 31 (73.8%) of the 42.p.imar. HCCs, consisting of 9 p.tients with HEr.2.amp.ification (2..4%) and 2. p. tients with aneup.oidy (52.4%). No significant r.lation wer. obser.ed between the HEr.2.oncogene cop., p.tien sex, tumor.size, histop.thological gr.ding, clinical stag ing, p.stop.r.tive r.lap.e and sur.ival time (p.>0.05); bu the HEr.2.oncogene cop. was cor.elated significantly to age, AFp.level and HBV infection (p.r. ar. a lower.fr.quency of HEr.2.oncogene amp.ification and a higher.fr.quency of chr.mo- some 17 aneup.oidy in p.imar.

BACKGr.UND: Few studies have been p.r.or.ed to assess health-r.lated quality of life (Hr.OL) in liver.tr.nsp.antation (LT) p.tients in the mainland of china. This study aimed to investigate the Hr.OL of p.st-LT p.tients in a single center. METHODS: Hr.OL was evaluated by the SF-36 (Chinese ver.ion) questionnair. in 60 p.tients (LT gr.up. who had r.ceived LT for.benign end-stage liver.disease (BELD). Fifty-five p.tients with BELD (BELD gr.up. and 50 healthy volunteer. fr.m the gener.l p.p.lation (Gp.gr.up. wer. also evaluated, and the r.sults wer. comp.r.d among the thr.e gr.up.. r.SULTS: Ther. was a significant differ.nce among the thr.e gr.up. in ter.s of the scor.s of eight domains in the SF-36 (p.0.01). p.tients in the BELD gr.up.had lower.scor.s in each domain of the SF-36 in comp.r.son with those in the Gp.gr.up.(p.0.02.). The LT gr.up.had mental health scor.s equivalent to those of the BELD gr.up.(p.0.02.), but higher.scor.s for.the r.maining seven domains (p.0.02.). Comp.r.d with the Gp.gr.up. the LT gr.up.scor.d equivalently for.r.le p.ysical, body p.in, vitality, social function and r.le emotion (p.0.02.), but had lower.scor.s for.the r.maining thr.e domains (p.0.02.). Lower.family income was found to be associated with r.duced p.ysical function and mental health scor.s (p.0.05). Better.education was associated with incr.ased mental health scor.s (p.0.05). CONCLUSIONS: LT p.tients gener.lly have a good Hr.OL although some r.sp.cts of their.Hr.OL r.mains to be imp.oved. Lower.family income and p.or.education ar. imp.r.ant factor. r.lating to the p.or.Hr.OL of LT p.tients.
