Relation of MiR-34a Expression in Diffuse Large B Cell Lymphoma with Clinical Prognosis / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To investigate the expression of miR-34a in serum of DLBCL patients, and to analyze its correlation with the expression of BCL-2 protein and clinical prognosis.</p><p><b>METHODS</b>The clinical data of 65 DLBCL patients and 22 cases of lymphonode reactive hyperplasia (RH) were collected, the serum expressions of miR-34a and BCL-2 were detected by real-time fluorescence quantitative PCR, and the relationship of miR-34a and BCL-2 expression with clinical pathological features and prognosis was analyzed.</p><p><b>RESULTS</b>The miR-34a lowly expressed in DLBCL and the BCL-2 highly expressed in DLBCL, the miR-34a expression level correlated negatively with BCL-2 expression (P<0.01). The survival time of patients with high expression of miR-34a was significantly longer than that of patients with miR-34a low expression. Multivariate Cox regression analysis revealed that the expression of miR-34a (P<0.01) and BCL-2 (P<0.01) as well as clinical staging (P<0.01) were independent factors influencing the prognosis of patients with DLBCL.</p><p><b>CONCLUSION</b>The low expression of miR-34a in DLBCL patients may be involved in the occurrence and development of diffuse large B cell lymphoma, the MiR-34a is correlated with prognosis of diffuse large B cell lymphoma.</p>

The clinical characteristics of 681 patients with diffuse large B-cell lymphoma / 中华血液学杂志

<p><b>OBJECTIVE</b>To analyze clinical features and the differences of GCB and non-GCB phenotypes for diffuse large B-cell lymphoma (DLBCL) in different age groups, Ki-67 index and international prognostic index (IPI).</p><p><b>METHODS</b>Clinical data of 681 patients with DLBCL hospitalized in West China Hospital from January 2000 to December 2010 were retrospectively analyzed.</p><p><b>RESULTS</b>Of these DLBCL cases, the median age was 56 years old with a male predominance, 51.4% stage III-IV, 37.6% B symptoms, 30.2% IPI 3-5 scores, 49.8% from extranodal sites, 29.0% gastrointestinal tract infiltration, 38.3% low absolute lymphocyte count (ALC), 56.1% elevated serum lactate dehydrogenase (LDH) level, 83.0% elevated β(2)-microglobulin (β(2)-MG) level. B symptoms was associated with bone marrow involvement with the odds ratio 5.212 (95%CI 2.821 - 9.632, P = 0.000). Among 268 with DLBCL patients classified by Hans' classification, 28.4% were GCB and 71.6% non-GCB. The proportions of patients with HBsAg-positive, elevated serum LDH level and Bcl-2 positive expression in non-GCB group was higher than those in GCB group (P < 0.05). The differences between GCB and non-GCB DLBCL were not revealed in terms of age subgroups, Ki-67 expression status and IPI subgroups. The high (≥ 60%) Ki-67 group included more patients with extranodal site involvement compared with the low (< 60%) Ki-67 group (51.8% vs 38.7%, P = 0.008). The proportion of patents with low ALC in IPI 3-5 scores group was higher than in IPI 0-2 scores group (P = 0.000). The multivariate analysis showed that high IPI had statistically significant negative influence on survival (P = 0.000).</p><p><b>CONCLUSIONS</b>Most patients with DLBCL were middle-aged male from our data. The patients with primary nodal (PN) was almost equal to those with primary extranodal (PEN). The most frequent extranodal site was gastrointestinal tract. The non-GCB phenotype was significantly more common than GCB phenotype in this study, and the non-GCB group included more patients with HBsAg-positive and Bcl-2 positive expression. Low ALC was observed predominantly in the high risk group. IPI score was an independent prognostic indicator for survival.</p>

Study on quality of flavone in various cultivars of Chrysanthemum morifolium for medicine / 中国中药杂志

<p><b>OBJECTIVE</b>To study on dynamic accumulation of various flavone in Chrysanthemum morifolium, in order to appraise the quality of flavone.</p><p><b>METHOD</b>The extract was hydrolyzed and the flavonoid components were determined by RP-HPLC.</p><p><b>RESULT AND CONCLUSION</b>In the samples from Tongxiang, Tezhongboju showed the highest flavonoids content with the total flavone 9.81%, quercetin 4.17 per thousand and apigenin 17.02 per thousand. In the samples from Sheyang, Hongxinju showed the highest content of luteolin with 6.84 per thousand. In the samples from Jiangning, Tezhongboju showed the highest content of total flavone with 7.59%, Yizhongdabaiju showed the highest content of quercetin with 2.78 per thousand, Sheyangxiaobaiju showed the highest content of luteolin with 4.27 per thousand, Sheyanghongxinju showed the highest content of apigenin with 11.20 per thousand. There were differences in the content of flavonoids among the different cultivars, and the same cultivars showed also different when planted in different areas.</p>
