OBJECTIVEThe aim of this study was to investigate the clinicopathological characteristics, effective treatment and prognosis in childhood and adolescent Hodgkin's lymphoma.

METHODSA total of 88 patients with childhood and adolescent Hodgkin's lymphoma were treated in the Cancer Hospital of CAMS from 1998 to 2005. The clinicopathological and follow-up data of the patients were retrospectively reviewed. The survival rate was calculated by Kaplan-Meier method and compared by log-rank test. COX multivariate prognosis analysis was performed.

RESULTSThe 2-year event-free survival rate of the 88 patients was 86.4%, the 5-year event-free survival rate was 61.4%, and the 5-year overall survival rate was 95.5%. Univariate analysis showed that the stage of disease (P = 0.033), "B" symptoms (P = 0.028), bulky disease (P = 0.007), splenomegaly (P = 0.050), LDH elevation (P = 0.020), chemotherapy regimen (P = 0.003) were prognostic factors in the 5-year event-free survival rate. Splenomegaly (P = 0.039), LDH elevation (P = 0.033), chemotherapy regimen (P = 0.008) were prognostic factors of 5-year overall survival rate. Multivariate analysis showed that chemotherapy regimen (P = 0.033), stage of disease (P = 0.023), LDH elevation (P = 0.008), "B" symptoms (P = 0.044), bulky disease (P = 0.009) were independent prognostic factors of 5-year event-free survival rate. The chemotherapy regimen (P = 0.012) and LDH elevation (P = 0.046) were independent prognostic factors of 5-year overall survival rate.

CONCLUSIONSThe non-ABVD chemotherapy regimen, stage IV disease, LDH elevation, associated with "B" symptoms and bulky disease are independent prognostic factors of 5-year event-free survival rate. LDH elevation and non-ABVD chemotherapy regimen are independent prognostic factors of 5-year overall survival rate.

Objective To observe the histopathological features,nuclear factor-κB (NFκB) and IKB expressions as well as calcium deposition of atherosclerosis plaques (AS) in apolipoprotein E (ApoE) and low density lipoprotein receptor (LDLR) knockout mice (ApoE-/-, LDLR-/- fed high-fat diet.Methods Eight C57BL/6J mice fed with normal diet were used as control,32 ApoE-/- mice and LDLR -/- mice were divided into normal diet and high-fat diet groups ( n =8 each).After 4 months,aorta was collected for morphologic ( HE,Oil Red O,Von Kossa ) and immunohistochemistry ( nuclear factor-κB,IKB,macrophage surface molecule-3, α-smooth activor protein ) analysis.Results Degree of AS in ApoE -/ - and LDLR-/- mice fed with high-fat diet were significantly severer than those fed with normal diet and AS was more significant in ApoE-/- mice than in LDLR -/- mice.NFκB and IKB expressions in high-fat diet group were significantly higher than the normal diet group ( P ＜ 0.05 ). Double-labeling of NFκB revealed dominant expression in smooth muscle cells.Calcium deposition was significantly more in ApoE-/- mice fed with high-fat diet than mice fed with normal diet (P ＜0.05) and was similar in LDLR-/- mice fed with high and normal diet (P ＞ 0.05 ).Conclusion High-fat diet contributes to the formation of AS plagues in ApoE -/- and LDLR -/- mice joined by upregulated NFκB and IKB expressions and calcium deposition.

OBJECTIVETo assess the efficacy of calcium-magnesium (Ca/Mg) infusion and glutathione (GSH) for preventing the neurotoxicity induced by oxaliplatin.

METHODSThis is a randomized, double blind, placebo controlled clinical trail. The patients receiving FOLFOX4 chemotherapy for their solid tumor were randomized to receive Ca/Mg, GSH or normal saline with chemotherapy simultaneously. The incidence and severity of oxaliplatin-induced neurotoxicity were observed. The ECOG performance status was recorded and compared among the 3 groups.

RESULTSNinety-three patients admitted in our department from Mar 2006 to Dec 2007 were entered into this study, including 29 patients in the Ca/Mg group, 33 in the GSH group and 31 in the chemotherapy alone group. The incidences of acute neurotoxicity were 82.8%, 90.9% and 93.5%, respectively. At the third cycle, the incidences of grade 1-2 chronic neurotoxicity were 37.9%, 48.5% and 42.0%, respectively. No grade 3 neuropathy was observed. After 6 cycles, the incidence of grade 1-2 neuropathy was increased to 68.2%, 88.9% and 85.2%, respectively. A lower percentage was observed in Ca/Mg arm without a statistically significant difference, and grade 3 neuropathy occurred in 5 patients. After 9 cycles, the incidence of grade 1-2 neuropathy was increased to 81.3%, 90.0% and 92.9%, respectively. Grade 3 neuropathy occurred in another 2 patients. No statistically significant difference was observed among the 3 arms. Changes of patient's ECOG score after chemotherapy were similar.

CONCLUSIONThis study didn't provide evidence that Ca/Mg infusion and GSH can prevent the oxaliplatin-induced neurotoxicity.

OBJECTIVETo investigate the clinical characteristics and treatment of desmoplastic small round cell tumor.

METHODSFive patients with DSRCT were diagnosed and treated in our Hospital from January 1999 to May 2009. Forty-eight cases with complete clinical data were collected and reviewed from 23 published reports. Therefore totally 53 patients with DSRCT were analysed. The survival rate was calculated by Kaplan-Meier method and compared by log-rank test.

RESULTSThe median age of all cases was 23 (1.5 - 66) years old at the time of diagnosis. 75.5% of patients were male. The most common presenting complaint was intra-abdominal mass or pain (77.4%). In 46 patients (86.8%), the primary tumor was located in the abdomen or pelvis. Fifteen (28.3%) had positive lymph nodes or distant parenchymal metastases. The median follow-up was 1.8 years (range, 0.1 - 10.0 years). The overall 1-, 3- and 5-year survivals were 45.8%, 20.8% and 5.7%, respectively. Forty-seven patients underwent surgery. Complete tumor resection was significantly correlated with long survival. The 1- and 3-year survival rates were 70.5% and 53.7% in patients treated with complete tumor resection compared to 37.2% and 4.8% in the incomplete tumor resection cohort (P = 0.0020). Thirty-four patients received chemotherapy and the 1- and 3-year survival rates were 60.1% and 35.2%, respectively, however, only 29.7% and 12.7% in patients without chemotherapy (P = 0.0396). Twelve patients had radiotherapy and the 1- and 3-year survival rates were 75.0% and 38.9%, respectively, compared with 36.9% and 14.8% in those without radiotherapy (P = 0.0314).

CONCLUSIONComplete tumor resection results in improved survival in patients with DSRCT. Chemotherapy and radiotherapy correlate with improved patient outcome. Multimodal therapy may improve the survival in patients with DSRCT.

OBJECTIVETo screen the differentially expressed miRNAs and their target genes in adipogenic differentiation of human bone marrow mesenchymal stem cells (hMSCs) to better understand the mechanism for regulating the balance between osteoblast and adipocyte differentiation.

METHODSCultured hMSCs were induced for adipogenic differentiation, and at 0, 7, 14, and 21 days of induction, the cells were examined for miRNA and mRNA expression profiles using miRNA chip and transcriptome sequencing (RNA-seq) techniques. Correlation analysis was carried out for the miRNAs and mRNAs of potential interest. The databases including TargetScan, PicTar and miRanda were used to predict the target genes of the differentially expressed miRNA.

RESULTSThe expression of miR-140-5p was down-regulated and leukemia inhibitory factor receptor (LIFR) expression increased progressively during adipogenic differentiation of hMSCs, showing a negative correlation between them. Target gene prediction using the 3 databases identified LIFR as the target gene of miR-140-5p.

CONCLUSIONmiRNA-140-5p may play an important role by regulating its target gene LIFR during adipogenic differentiation of hMSCs.
