RNA-seq Was Used to Obtain the Key Genes in the Regulation of Conjugated Linoleic Acid on Intramuscular Fat Metabolism in Royal Chicken / 中国生物化学与分子生物学报

Transcriptome sequencing was used to obtain the differentially expressed genes of conjugated linoleic acid (CLA) on the basal diet of Royal chickens on intramuscular fat metabolism in related signal pathways and candidate genes that may play important roles by bioinformatics analysis, which could provide a further understanding of the molecular mechanism of CLA on intramuscular fat deposition. In this study, 55-day-old healthy Royal chickens were selected as experimental animals, and 0%, 1% and 2% of CLA were added to the basic diet. The pre-feeding period was 1 week and the normal feeding period was 6 weeks. The breast muscle tissues were collected for transcriptome sequencing, and the sequencing data were subjected for differential expression analysis, such as GO function and KEGG pathway enrichment analysis of differentially expressed genes. Differentially expressed genes related to breast muscle lipid metabolism were screened out, and qRT-PCR was used to verify differentially expressed genes. The results showed that a total of 1 065 differentially expressed genes were obtained, of which 703 were up-regulated genes and 362 were down-regulated genes. GO enrichment results show that differentially expressed genes are concentrated in cellular processes, single-biological processes, biological regulation and metabolic processes in biological processes. Enrichment analysis of KEGG signaling pathway shows that differentially expressed genes were significantly enriched in focal adhesion, unsaturated fatty acid biosynthesis, fatty acid biosynthesis, and steroid biosynthesis. Totally 11 candidate genes were found mainly related to intramuscular fat metabolism, including FADS1, FADS2, ELOVL5, ACOX2, SLC27A1, FABP5, LPL, LOC107050163, ENSGALG00000030996, ENSGALG00000005043 and ENSGALG00000048882. Six genes were randomly selected for qRT-PCR verification, and their relative expression changes were consistent with the sequencing results. This study screened the differentially expressed genes related to CLA affecting breast muscle lipid metabolism in Royal chickens, and analyzed 11 genes related to fat metabolism, laying the foundation for revealing the molecular mechanism of CLA regulating intramuscular fat deposition.

Survival analysis of children with stage II testicular malignant germ cell tumors treated with surgery or surgery combined with adjuvant chemotherapy / 癌症

For children with stage II testicular malignant germ cell tumors (MGCT), the survival is good with surgery and adjuvant chemotherapy. However, there is limited data on surgical results for cases in which there was no imaging or pathologic evidence of residual tumor, but in which serum tumor markers either increased or failed to normalize after an appropriate period of half-life time post-surgery. To determine the use of chemotherapy for children with stage II germ cell tumors, we analyzed the outcomes (relapse rate and overall survival) of patients who were treated at the Sun Yat-sen University Cancer Center between January 1990 and May 2013. Twenty-four pediatric patients with a median age of 20 months (range, 4 months to 17 years) were enrolled in this study. In 20 cases (83.3%), the tumors had yolk sac histology. For definitive treatment, 21 patients underwent surgery alone, and 3 patients received surgery and adjuvant chemotherapy. No relapse was observed in the 3 patients who received adjuvant chemotherapy, whereas relapse occurred in 16 of the 21 patients (76.2%) treated with surgery alone. There were a total of 2 deaths. Treatment was stopped for 1 patient, who died 3 months later due to the tumor. The other patient achieved complete response after salvage treatment, but developed lung and pelvic metastases 7 months later and died of the tumor after stopping treatment. For children treated with surgery alone and surgery combined with adjuvant chemotherapy, the 3-year event-free survival rates were 23.8% and 100%, respectively (P = 0.042), and the 3-year overall survival rates were 90.5% and 100%, respectively (P = 0.588). These results suggest that adjuvant chemotherapy can help to reduce the recurrence rate and increase the survival rate for patients with stage II germ cell tumors.

Brain metastasis in children with stage 4 neuroblastoma after multidisciplinary treatment / 癌症

<p><b>INTRODUCTION</b>Brain metastasis is common in relapsed neuroblastoma patients, but the characteristics of brain metastasis remain largely unknown. This study aimed to investigate the status of brain metastasis with neuroblastoma in South China.</p><p><b>METHODS</b>In this retrospective case-based study, 106 patients with stage 4 neuroblastoma from the Department of Pediatric Oncology in Sun Yat-sen University Cancer Center between January 2004 and May 2013 were included. The incidence, risk factors, and survival status of these patients were reviewed and analyzed.</p><p><b>RESULTS</b>Of the 106 patients, 11 (10.4%) developed brain metastasis, accounting for 20.0% of 55 patients with relapse or progression. The age at initial diagnosis of the 11 patients ranged from 2 to 10 years (median 4 years), which was younger than that of the patients without brain metastasis (median 5 years, range 1-10 years, P=0.073). The male to female ratio of the 11 patients was 8:3, which was not significantly different from that of the patients without brain metastasis (P=0.86). Patients with brain metastasis had higher lactate dehydrogenase levels than those without brain metastasis, but the differences were not significant (P=0.076). Eight patients died, and 3 patients survived. The median interval from the initial diagnosis to the development of brain metastasis was 18 months (range 6-32 months). The median survival was 4 months (range 1 day to 29 months) after the diagnosis of brain metastasis. The median interval from the manifestation of brain metastasis to death was 3 months (range 1 day to 11 months).</p><p><b>CONCLUSIONS</b>High-risk factors for brain metastasis in cases of neuroblastoma include bone marrow involvement and a younger age at initial diagnosis. Nevertheless, multiple treatment modalities can improve disease-free survival.</p>

Diagnostic values of vascular endothelial growth factor and epidermal growth factor receptor for benign and malignant hydrothorax / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Hydrothorax, as one of the common complications of malignant tumors, still cannot be sensitively detected in clinical practice, thus requiring a sensitive, specific method for diagnosis. The aim of this study was to analyze the correlation between levels of vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) in patients with benign and malignant hydrothorax.</p><p><b>METHODS</b>The contents of VEGF in the pleural effusion and serum of the patients with malignant pleural effusion (n = 35) and benign pleural effusion (n = 30) were detected by double antibody sandwich enzyme linked immunosorbent assay. The gene copy number level of EGFR in pleural effusion was detected by fluorescence in situ hybridization (FISH). The points with the highest sensitivity and specificity were selected as the critical values to calculate the diagnostic value of the VEGF in pleural effusion and serum, and EGFR gene copy number in pleural effusion.</p><p><b>RESULTS</b>The contents of VEGF in pleural effusion and serum of patients with malignant hydrothorax were (384.91 ± 120.18), and (129.62 ± 46.35) ng/L, respectively, which were significantly higher than those of the patients with benign hydrothorax (207.97 ± 64.04), (63.49 ± 24.58) ng/L (P < 0.01). The sensitivity and specificity of detecting VEGF in pleural effusion were 80.0% and 96.7% (the boundary value was 297.06 ng/L), respectively for diagnosing benign and malignant hydrothorax. The sensitivity and specificity of serum were 74.3% and 96.7%, respectively (the boundary value was 99.21 ng/L) for diagnosing benign and malignant hydrothorax. The diagnostic efficiencies of EGFR and VEGF in hydrothorax were similar. There was a significant correlation between EGFR and VEGF in hydrothorax (P < 0.01).</p><p><b>CONCLUSIONS</b>VEGF and EGFR play important roles in the formation of pleural effusion. VEGF differed significantly in benign and malignant pleural effusions, which contributed to differential diagnosis results of benign and malignant pleural effusions. It is feasible to detect the gene copy number of the pleural effusion cell mass EGFR by FISH technique. Joint detection can improve the diagnostic sensitivity.</p>

The clinical characteristics and treatment outcome of 57 children and adolescents with primary central nervous system germ cell tumors / 癌症

Primary central nervous system germ cell tumors (CNS-GCTs) in children and adolescents have unique clinical features and methods of treatment compared with those in adults. There is little information about Chinese children and adolescents with CNS-GCTs. Therefore, in this study we retrospectively analyzed the clinical features and treatment outcome of Chinese children and adolescents with primary CNS-GCTs. Between January 2002 and December 2012, 57 untreated patients from a single institution were enrolled. They were diagnosed with CNS-GCTs after pathologic or clinical assessment. Of the 57 patients, 41 were males and 16 were females, with a median age of 12.8 years (range, 2.7 to 18.0 years) at diagnosis; 43 (75.4%) had non-germinomatous germ cell tumors (NGGCTs) and 14 (24.6%) had germinomas; 44 (77.2%) had localized disease and 13 (22.8%) had extensive lesions. Fifty-three patients completed the prescribed treatment, of which 18 underwent monotherapy of surgery, radiotherapy, or chemotherapy, and 35 underwent multimodality therapies that included radiotherapy combined with chemotherapy or surgery combined with chemotherapy and/or radiotherapy. PEB (cisplatin, etoposide, and bleomycin) protocol was the major chemotherapy regimen. The median follow-up time was 32.3 months (range, 1.2 to 139 months). Fourteen patients died of relapse or disease progression. The 3-year event-free survival (EFS) and overall survival rates for all patients were 72.2% and 73.8%, respectively. The 3-year EFS was 92.9% for germinomas and 64.8% for NGGCTs (P = 0.064). The 3-year EFS rates for patients with NGGCTs who underwent monotherapy and multimodality therapies were 50.6% and 73.5%, respectively (P = 0.042). Our results indicate that multimodality therapies including chemotherapy plus radiotherapy were better treatment option for children and adolescents with CNS-GCTs.

Germinal-center type B-cell classification and clinical characteristics of Chinese pediatric diffuse large B-cell lymphoma: a report of 76 cases / 癌症

Pediatric diffuse large B-cell lymphoma (DLBCL) is a highly aggressive disease with unique clinical characteristics. This study analyzed the germinal-center type B-cell (GCB) classification and clinical characteristics of Chinese pediatric DLBCL. A total of 76 patients with DLBCL newly diagnosed in Sun Yat-sen University Cancer Center between February 2000 and May 2011, with an age younger than 18 years, were included in the analysis. The male/female ratio was 3.47:1. The median age was 12 years (range, 2 to 18 years), and 47 (61.8%) patients were at least 10 years old. Of the 76 patients, 48 (63.2%) had stage III/IV disease, 9 (11.8%) had bone marrow involvement, 1 (1.3%) had central nervous system (CNS) involvement, and 5 (6.6%) had bone involvement. The GCB classification was assessed in 45 patients: 26 (57.8%) were classified as GCB subtype, and 19 (42.2%) were classified as non-GCB subtype. The modified B-NHL-BFM-90/95 regimen was administered to 50 patients, and the 4-year event-free survival (EFS) rate was 85.8%. Among these 50 patients, 31 were assessed for the GCB classification: 17 (54.8%) were classified as GCB subtype, with a 4-year EFS rate of 88.2%; 14 (45.2%) were classified as non-GCB subtype, with a 4-year EFS rate of 92.9%. Our data indicate that bone marrow involvement and stage III/IV disease are common in Chinese pediatric DLBCL patients, whereas the percentage of patients with the GCB subtype is similar to that of patients with the non-GCB subtype. The modified B-NHL-BFM-90/95 protocol is an active and effective treatment protocol for Chinese pediatric patients with DLBCL.

Safety of in vitro amplified HLA-haploidentical donor immune cell infusions for childhood malignancies / 癌症

In vitro amplified human leukocyte antigen (HLA)-haploidentical donor immune cell infusion (HDICI) is not commonly used in children. Therefore, our study sought to evaluate its safety for treating childhood malignancies. Between September 2011 and September 2012, 12 patients with childhood malignancies underwent HDICI in Sun Yat-sen University Cancer Center. The median patient age was 5.1 years (range, 1.7-8.4 years). Of the 12 patients, 9 had high-risk neuroblastoma (NB) [7 showed complete response (CR), 1 showed partial response (PR), and 1 had progressive disease (PD) after multi-modal therapies], and 3 had Epstein-Barr virus (EBV)-positive lymphoproliferative disease (EBV-LPD). The 12 patients underwent a total of 92 HDICIs at a mean dose of 1.6×10(8) immune cells/kg body weight: 71 infusions with natural killer (NK) cells, 8 with cytokine-induced killer (CIK) cells, and 13 with cascade primed immune cells (CAPRIs); 83 infusions with immune cells from the mothers, whereas 9 with cells from the fathers. Twenty cases (21.7%) of fever, including 6 cases (6.5%) accompanied with chills and 1 (1.1%) with febrile convulsion, occurred during infusions and were alleviated after symptomatic treatments. Five cases (5.4%) of mild emotion changes were reported. No other adverse events occurred during and after the completion of HDIDIs. Neither acute nor chronic graft versus host disease (GVHD) was observed following HDICIs. After a median of 5.0 months (range, 1.0-11.5 months) of follow-up, the 2 NB patients with PR and PD developed PD during HDICIs. Of the other 7 NB patients in CR, 2 relapsed in the sixth month of HDICIs, and 5 maintained CR with disease-free survival (DFS) ranging from 4.5 to 11.5 months (median, 7.2 months). One EBV-LPD patient achieved PR, whereas 2 had stable disease (SD). Our results show that HDICI is a safe immunotherapy for childhood malignancies, thus warranting further studies.

Lymphoma and cerebral vasculitis in association with X-linked lymphoproliferative disease / 癌症

Lymphoma is seen in up to 30% of patients with X-linked lymphoproliferative disease (XLP), but cerebral vasculitis related with XLP after cure of Burkitt lymphoma is rarely reported. We describe a case of a 5-year-old boy with XLP who developed cerebral vasculitis two years after cure of Burkitt lymphoma. He had Burkitt lymphoma at the age of 3 years and received chemotherapy (non-Hodgkin's lymphoma-Berlin-Frankfurt-Milan-90 protocol plus rituximab), which induced complete remission over the following two years. At the age of 5 years, the patient first developed headache, vomiting, and then intellectual and motorial retrogression. His condition was not improved after anti-infection, dehydration, or dexamethasone therapy. No tumor cells were found in his cerebrospinal fluid. Magnetic resonance imaging showed multiple non-homogeneous, hypodense masses along the bilateral cortex. Pathology after biopsy revealed hyperplasia of neurogliocytes and vessels, accompanied by lymphocyte infiltration but no tumor cell infiltration. Despite aggressive treatment, his cognition and motor functions deteriorated in response to progressive cerebral changes. The patient is presently in a vegetative state. We present this case to inform clinicians of association between lymphoma and immunodeficiency and explore an optimal treatment for lymphoma patients with compromised immune system.

Objective To observe the effects of early rehabilitation on the serum neuron specific enolase (NSE) levels of patients with acute cerebral infarction.MethodsSixty patients with acute cerebral infarction were randomly divided into a rehabilitation group and a control group. All received routine treatment at the acute stage, including anti-platelet aggregation medication, drugs for improving microcirculation, neurotrophic agents and prompt treatment of any complications. Patients in the rehabilitation group also received systemic rehabilitation training beginning immediately after their vital signs had been stabilized. NSE in serum was assayed before treatment and after 3, 7and 14 days. National Institutes of Health stroke scale (NIHSS) scores were evaluated at each time point, and the two groups were compared.ResultsThere was no significant difference in serum NSE or NIHSS scores between the two groups pre-treatment. Both groups improved to a certain extent, but the improvements in the rehabilitation group were significantly better than in the control group, as their NSE levels at 7 days and NIHSS scores at 14 days were both significantly better.ConclusionsEarly rehabilitation intervention contributes to reducing serum NSE levels after acute cerebral infarction, lessening brain injury, and thereby promoting the recovery of damaged neural function.That may be one of the mechanisms by which early rehabilitation promotes functional recovery in patients with acute cerebral infarction.
