Objective To investigate the immunophenotype features of children with acute B-lymphoblastic leukemia(B-ALL) combined with fusion gene expressing after to analyze the results of the 43 fusion genes. Methods Real-time fluorescent probe PCR assay was used for the detection of fusion genes in 120 cases of children from Shenzhen Children's Hospital with B-ALL newly or recurrently diagnosed from Oct 2016 to Dec 2018. Multi-parameter flow cytometry(FCM) was used for the detection of the immunophenotype in children with B-ALL. Results Of all the 120 cases, the fusion genes were detected at positive rate of 37.5%(45/120), included TEL/AML1 27 cases, E2 A/PBX1 7 cases, BCR/ABL1 6 cases, MLL 4 cases, TLS/ERG 1 cases. The positive rate of leukemia fusion gene had statistically difference among fusion genes positive groups based on age(P<0.01). There was no statistically difference in the gender distribution(P>0.05). The expressing of CD19 was at positive rate of 100% in all of the groups. The rate of the common-B-ALL was the highest B-ALL subtype in the TEL/AML1 positive groups(77.8%). The stem /progenitor associated antigen CD34 was at positive rate of 81.5%. The pre-B-ALL was the main subtype in the E2 A/PBX1 group, which was no expression of the known T-ALL associated antigen MyAg antigen. There was statistically difference in the positive rate of MyAg expression among all of the groups(P<0.01), with the highest rate in the BCR/ABL1 group(100%). Conclusion There were certain distribution features in age composition and immunophenotype of children with B-ALL carrying five kinds of common fusion genes. The characteristic changes of the immunophenotype of B-ALL may be used to predict the expression of fusion genes and improve the accuracy of fusion genes by the supplementary role of immunophenotype analysis.

目的 检测外周血循环肿瘤细胞(circulating tumor cell, CTC)在原发性肝癌患者中的表达情况,并探讨CTC动态变化及其相对于甲胎蛋白(Alpha fetoprotein AFP)对原发性癌患者术后复发转移的预测作用。方法 收集原发性肝癌患者134例,肝脏良性病变患者72例,检测外周血 CTC 数目,同时检测AFP的表达水平,分析 CTC 与 AFP 的相关性。然后在134名原发性肝癌患者中筛选出成功行肝癌根治术的患者,共86例,检测这86名患者术前、术后外周血CTC和AFP,分析CTC和AFP对原发性肝癌术后复发转移的评估价值。结果 原发性肝癌患者外周血CTC阳性率高于肝脏良性病变患者,差异有统计学意义(P＜0.05);原发性肝癌患者CTC水平与AFP水平、淋巴结转移、肿瘤结节多少有关,与年龄、性别、肿瘤直径、分化程度、肝硬化有无、TNM分期无关;原发性肝癌患者CTC和AFP生存分析显示,原发性肝癌根治术后早期复发转移与CTC和AFP密切相关;CTC较阳性对术后复发转移具有更好的诊断价值,二者联合对复发转移预测价值最高。结论 CTC可以做为一个比传统肿瘤标志物更好的对原发性肝癌术后复发转移进行监测的指标,与肿瘤标志物联合检测预测价值更高。

Objective To detect the expression of peripheral blood circulating tumor cells CTC in patients with primary liver cancer and to explore the dynamic changes of CTC and its predictive effect on postoperative recurrence and metastasis of primary cancer. Methods The number of CTC in peripheral blood was measured in 134 patients with primary liver cancer and 72 patients with benign liver disease, the expression of AFP was detected, and the correlation between CTC and AFP was analyzed. Then 86 patients with primary liver cancer were selected from 134 patients with primary liver cancer who underwent radical hepatectomy. The values of CTC and AFP in evaluating recurrence and metastasis of primary liver cancer before and after operation were analyzed by CTC and AFP, in peripheral blood of these 86 patients. Results The positive rates of CTC in peripheral blood of patients with primary liver cancer were higher than that of patients with benign liver disease(P< 0.05). The levels of CTC in patients with primary liver cancer were related to AFP level, lymph node metastasis and the number of tumor nodules, but not to age, sex, tumor diameter, differentiation degree, liver cirrhosis and TNM stage. The survival analysis of CTC and AFP in patients with primary liver cancer showed that the early recurrence and metastasis of primary liver cancer after radical resection were closely related to the positive rate of CTC and AFP, and the positive rate of CTC was more effective than that of AFP positive in the diagnosis of recurrence and metastasis after operation, and the combination of the two had the highest predictive value for recurrence and metastasis. Conclusion CTC may be used as a better index to monitor postoperative recurrence and metastasis of primary liver cancer than traditional tumor markers. The combined detection prediction value of tumor markers is higher.

Methods HOS cells were treated with evodiamine at 0, 3, 6, and 12 μmol/L for 48 hours, Hoechst-33258 fluorescence staining was used to observe the morphological changes of HOS nuclei after treatment with different concentrations of evodiamine.The cell cycle distribution of HOS cells treated with 3 μmol/L evodiamine was detected by flow cytometry. Results 3,6,12 μmol/L osteosarcoma treated with evodiamine, the cells showed typical changes such as apoptotic nuclear fragmentation, and it became more obvious with the increase of drug dosage. Inhibition of proliferation in vitro in a dose-dependent manner.HOS cells were treated with 3 μmol/L evodiamine for 0, 24, 48, 72 h. The cell cycle changes of each group were as follows: G0/G1 phase: control group(51.12±2.13)%, 24 h(19.17±1.02)%, 48 h(16.94±1.67) %, 72 h(11.05±1.25)%;S phase: control group(32.92±0.73)%, 24 h(31.00±1.42)%, 48 h(32.38±3.03)%, 72 h(29.18±2.87)%;G2/M period: control group(16.01±2.26)%, 24 h(49.82±0.62)%, 48 h(50.6767±2.80)%, 72 h(59.56±1.97)%. Conclusion Analysis of the above results revealed that evodiamine can induce G2/M phase arrest in human osteosarcoma HOS cells, but the S phase changes are not obvious. It indicated that evodiamine would inhibit the proliferation of osteosarcoma cells and block the cell cycle in G2/M phase.
