ABSTRACT
Burkitt lymphoma (BL) is an aggressive B-cell non-Hodgkin lymphoma which often occurs in children. The cure rate of BL is significantly increased with the wide application of short-duration and high-intensity immunochemotherapy, however, chemotherapy-related adverse reactions are still a big problem in adult patients and human immunodeficiency virus (HIV) positive patients. Meanwhile, the absence of effective immune targeting new drugs in patients with relapsed and refractory BL needs to be solved clinically. How to optimize the therapeutic regimen to reduce the chemotherapy-related adverse reactions and develop effective immune targeting new drugs is the hot spot in current research. This paper reviews the treatment progress of BL according to the 59th American Society of Hematology (ASH) Annual Meeting.
ABSTRACT
Objective:To explore the expression and biological functions of miR-346 in nasopharyngeal carcinoma.Methods:63 cases nasopharyngeal carcinoma tissue and 34 cases nasopharyngeal non-cancer tissues were collected,the miR-346 expression were detected by Real-time PCR between nasopharyngeal carcinoma tissue and nasopharyngeal non-cancer tissues,6 strains of human nasopharyngeal carcinoma cell lines and 1 strain of normal nasopharyngeal epithelial cell immortalized NP69.Two cell lines with middle expression levels in human nasopharyngeal carcinoma cells lines were selected,and transfected into miR-346 inhibitor,the control group (NC group) were with negative control plasmid transfection,miR-346 expression in two groups were detected by Real-time PCR,the proliferation,apoptosis were detected by Brdu-ELISA and flow cytometry,the migration and invasion were detected by Transwell Chambers experiments.Results:Compared with the nasopharyngeal non-cancer tissues,the miR-346 expression in nasopharyngeal carcinoma tissues was significantly increased (P =0.000);compared with the normal nasopharyngeal epithelial cells NP69.the miR-346 expression in human nasopharyngeal carcinoma cell lines was significantly increased (P＜0.05).The CNE-1 and CNE-2 were chose,after the miR-346 inhibitor transfection,the miR-346 expression were significantly lower compared with NC group,the difference was statistically significant (P＜0.05).The proliferation of two kinds of nasopharyngeal carcinoma cell CNE-1 and CNE-2 were restrained after transfection,the difference showed statistically significant 3 days after transfection (P ＜ 0.05).The apoptosis increased significantly,and the migration cell numbers and invasion cell numbers decreased significantly compared with NC group,the differences were statistically significant (P＜0.05).Conclusion:miR-346 is overexpression in nasopharyngeal carcinoma,down-regu-lation of miR-346 inhibits the proliferation,migration,invasion,promotes the apoptosis,miR-346 may act as a oncogene and play an important role in the pathogenesis of nasopharyngeal carcinoma.
ABSTRACT
Objective:To investigate the expression and biological significance of MicroRNA-204 in nasopharyngeal carcinoma (NPC). Methods: qRT-PCR was applied to detect the relative expression of miR-204 in 43 paired nasopharyngeal carcinoma in comparison to the normal nasal mucosa tissues. Pearson chi-square test was used to analyze the relationship between the miR-204 expression and clinical features. The expressions of Bcl-2 and SIRT1 were measured by immunohistochemistry ( IHC ) , Spearman correlation analysis was used to analyze the relationship between miR-204 and Bcl-2,as well as SIRT1. We then transfected the miR-204 mimics into CNE-2 cells,then the Western blot was used to detect the expression of Bcl-2 and SIRT1,which were considered as the potential targets of miR-204. Results:The relative expressions of miR-204 was significantly downregulated in NPC tissues compared to those of the matched normal tumor-adjacent tissues(P<0. 05). Low expression of miR-204 was significantly associated with lymphatic metastasis(P<0. 05) and advanced TNM stage(Ⅲ+Ⅳ,P<0. 05). The expressions of Bcl-2 and Sirt1 in lower miR-204 level group were both higher than in higher miR-204 level group ( P<0. 05 ) . Both the mRNA and protin expression in CNE-2 cells were down-regulated after transfection. Conclusion: Low expression of miR-204 is related to the malignant clinicopathological features in NPC tissues,and miR-204 may through down-regulate Bcl-2 and SIRT1 to suppress NPC genesis and development.
ABSTRACT
ObjectiveTo understand the difference in characteristics between juvenile dermatomyositis (JDM) and adult dermatomyositis (ADM).Methods Sixty-one cases of JDM were retrospectively analyzed and compared with 30 cases of ADM. Results The rashes were presented as the initial symptom in all expect one JDM patients. Gottron’s papules were presented in 90% JDM patients and 67% ADM patients. Calcium deposition was presented in 7% JDM patients and none of the ADM patients. The cardiovascular system was involved in 7 % JDM patients and 23% ADM patients. Cancer occurred in none of JDM patients and 13% ADM patients. In JDM and ADM patients, the ratio of elevated muscle enzymes from highest to lowest was LDH, hy-droxybutyric acid enzyme, CK-MB, AST, and CK. The positive ratio of magnetic resonance (MRI) all exceeded 80% in JDM and ADM groups. Two cases died in each group.Conclusions The clinical presentation of JDM is basically the same as that of ADM. The most common initial symptoms in JDM are skin rashes and Gottron's papules. Cardiovascular disease and cancer are less in JDM than in ADM. MRI is valuable in the diagnosis of DM.
ABSTRACT
Objective To observe the influence of early postoperative feeding in the healing of intestinal anastomosis in rabbits,and to clarify preliminarily the relationships between early postoperative feeding after gastrointestinal surgery and gastrointestinal anastomotic fistula formation and healing time in rabbits.Methods 48 rabbits were randomly divided into experimental group and control group, then they were treated with gastrointestinal anastomosis.The rabbits in experimental group were fed with liquid diet 24 h after operation,and the rabbits in control group were fed nothing after operation and supplied by total parenteral nutrition.Two rabbits of each group were selected for exploratory laparotomy on the 3rd,5th,7th,10th and 15th day after operation,and the healing rate of anastomosis,the anastomotic bursting pressure,the anastomotic breaking strength,and the hychoxyproline level of anastomosis were observed.Results The healing rate of anastomosis in control group was 91.6%(22/24), and the healing rate of anastomosis in experimental group was 95.8%(23/24),there was no significant difference between two groups(P>0.05).The anastomotic bursting pressures of the rabbits in two groups were decreased remarkably at the 72nd hour after operation,which was the lowest point,and they were increased remarkably on the 5th day after operation,but the anastomic bursting pressure in experimental group was a little lower than that in control group,and it reached the peak on the 7th day after operation in control group. On the 10th day after operation,the anastomic bursting pressure in control group was a little lower than that on the 7th day after operation,but the anastomic bursting pressure in experimental group reached the peak.There were no significant differences of anastomic bursting pressure at different time points between two groups(P>0.05).The anastomotic breaking strength had no significant difference between two groups at the 72nd hour after operation,both of them reached the lowest points,however the anastomtic breaking strengths in two groups were increased remarkably on the 10th day after operation,and reached the peaks.but there were no significant differences of anastomic breaking strength at different time points between two groups (P>0.05 ). The hychoxyproline level of anastomosis:in experimental group was a little lower than that in control group at the 72tnd hour after operation,and both of them reached the peaks on the 7th day after operation;but there were no significant differences of hychoxyproline levels of anastomosis at different time points between two groups(P>0.05).Conclusion Early postoperative feeding can not cause the increase of anasmotic healing time and the incidence rate of gastrointestinal anastomotic fistula.
