Background Choroidal melanoma(CM)is a common form of primary ocular cancer in adults.It is reported that indomethacin has inhibitory effect on many tumor in vitro and in vivo,but whether it can inhibit the growth of CM has not been published. Objective This study was to investigate the anti-tumor activity of indomethacin on the growth of human CM OCM-1 cell xenografts in nude mice. Methods OCM-1 cells were subcutaneously implanted on 24 SPF female BALB/C.nu/nu nude mice to establish ectopic models of human CM.The nude mice with the tumor 5 mm were randomly divided into 4 groups:untreated group,normal saline solution(NS) group,indomethacin 1 ms/kg group,indomethacin 2 ms/kg group.The 1 mS/kg or 2 ms/kg indomethacin was intraperitoneally injected for 14 consecutive days in indomethacin 1 ms/kg group and indomethacin 2 me/kg group respectively.and 0.2 ml of 2%NS-DMSO was used at a same way in the NS group.No any agent was used as the untreated group.The volume and weight of implanted tumor as well as inhibitory rates of indomethaein on tumor were calculated.The expression of ki67 and survivin proteins were measured with immunohistochemistry,and the expression of survivin mRNA in CM was assessed by RT-PCR. ResuIts The tumor of indomethacin treatment group was reduced in volume and weight with a significant difference between treatment group and control group as well as indomethacin 1 ms/ks group and indomethacin 2 ms/kg group(P<0.05).The inhibitory rate of indomethacin 1 ms/kg and 2 ms/kg for tumor was 22.86%,48.00%respectively.The prolifiration index (PI)of ki67 in these 4 groups were (76.73±3.34)%,(73.30±2.95)%,(55.97±2.24)%,(32.87±2.91)%respectively,and significant difference was found in PI between indomethacin 2 mg/kg group and untreated group or NS group(P<0.05),but there was not significant difference between indomethacin 1 mg/kg and 2 ms/kg group(P>0.05).Compared with the control group,the indomethacin treatment groups showed the decreased expression of survivin protein and mRNA,and significant difference was found between indomethaein 2 ms/kg group and untreated group or NS group(P<0.05),however,no significant difference was found between indomethacin 1 mg/kg and 2 mg/kg group(P>0.05). Conclusion Indomethacin inhibits the growth of CM in nude mice through inhibiting the expression of survivin in the tumor and accelerating cell apoptosis and inhibiting tumor cell proliferation.

Objective To discuss the clinical manifestations, diagnosis and treatment of solidpseudopapillary tumor of the pancreas (SPTP) in children. Methods Clinical data of 12 cases of SPTP admitted to Beijing Children's Hospital from Mar 2001 to Mar 2007 were collected and analyzed retrospectively. Result There were 7 females and 5 males among the patients. The mean age was 13.6 years. The main symptoms were abdominal pain and mass. Tumors located in the head in 4 cases, in the body and tail of the pancreas in 8 cases. Five cases underwent tumor enucleations, one case underwent body resection of the pancreas, two cases underwent Whippple's procedure including one recurrent case, five cases underwent body and tail resection of the pancreas plus splenectomy. All these 12 cases were followed up for 6 months to 6 years. One case lost follow-up 6 months after body and tail resection of the pancreas plus spleneetomy. Another one suffered from live tumor one year after operation and refused surgical exploration and lost follow-up. The other 10 cases were still alive. Conclusion SPTP are predominantly seen in adolescent females. For its benign clinical behavior and relatively good prognosis, surgical resection is the main choice of therapy.

Objective To investigate the correlation between pathogens and spectrum of disease in infants with human cytomegalovirus(HCMV) active infection.Methods A total of 378 cases of HCMV infection diagnosed by the identification of HCMV IgM or PP65 antigen of HCMV.HCMV gB genotyping was carried out by nested PCR and restriction fragment length polymorphism(RFLP) in 107 cases.The results of pathogen,spectrum of disease and clinic feature were analyzed.Results In all 378 infant patients with HCMV,27.78% were systemic infection and 72.22% involved just single organ.Hepatitis,HCMV inclusion disease,thrombocytopenic purpura,pneumonia were pre- dominant with 33.07%,27.78%,13.49%,6.35% respectively.The rate of HCMV inclusion dis ease in infants younger than 2 weeks was higher than in those aged from 3 12 weeks(P ~ 0.05) and children older than 12 weeks(P<0.01).Infants with higher rate of PP65 antigen positive cells were apt to systemic infection than those with lower rate of PP65 positive cells(P<0.01).Infants,who were positive by detections of all three methods,were apt to systemic infection than others(P<0.01). Moreover,infants positive of IgM and PP65 antigen were apt to systemic infection than those just positive by one of the two methods(P<0.01).The result of gB genotype analysis in 107 cases showed 53 cases of gBⅠ,20 of gBⅡ.18 of gBⅢ.7 of gBⅠ+gBⅡ,5 of gBⅠ+gBⅢand 4 of gBⅡ+gBⅢ,and gBⅣwas not found.Conclusion HCMV could infect multiple organs and have some different clinic features.Combination of different methods can increase the sensitivity to detect the pathogen.The gBⅠgenotype is most prevalent in these infants.
