Next generation sequencing (NGS) has been applied in scientific research and clinical practice of mature lymphoid malignancies. The applications of NGS in the study of pathogenesis, treatment and prognosis evaluation, mechanisms of resistance to treatment in lymphoid malignancies have been reported in the 57th American Society of Hematology (ASH) annual meeting. This article summarized the advances in the use of NGS in mature lymphoid malignancies by reviewing several representative reports.

Objective To observe brain functional activity of patients with arrhythmia after radiofrequency ablation with amplitude of low-frequency fluctuation (ALFF).Methods Twenty-six patients with anxiety disorder after radiofrequency catheter ablation (RFCA) were included as RFCA group.Age and sex matched twenty-six healthy volunteers were included as control group.The difference of ALFF between the two groups was analyzed by two-sample t test.Partial correlation between extracted values from dysfunctional brain regions and hamilton anxiety scale (HAMA) scores were investigated.Results Compared with control group,ALFF of left middle temporal gyrus,right putamen,left amygdala significantly increased,and left dorsolateral prefrontal cortex (DLPFC),right praecuneus,left middle frontal gyrus and right middle occipital gyus significantly decreased in RFCA group (Alphasim correction,P＜0.01).ALFF values of left DLPFC were negatively correlated with HAMA scores (r=-0.872,P=0.013).Conclusion The brain activity of RFCA patients in resting state is abnormal.ALFF can provide more evidences for the pathogenesis of the disease.

Objectives To systematically evaluate the effect of music given to pregnant rats on the development of brain functions in the offspring rats and to provide scientific evidence for the application of antenatal musical training and the promotion of welfare for laboratory animals.Methods We comprehensively retrieved and collected the research literatures related to the effect of music on brain function development in offsprings of the pregnant rats from Pubmed,Web of Science,Cochrane Library,Wanfang,Weipu,CNKI and CBMdisc.The retrieval time was set from the foundation date of databases to 2 April,2016.We selected literatures according to the inclusion and exclusion criteria,evaluated their utilities,then extracted and qualitatively described the data.Results Seven experimental studies were selected in this study including 4 published in Chinese and 3 in English.The object laboratory animals of those studies were Wistar or SD rats.Music materials involved comfort music,classic music,violin concerto(Liangzhu/The butterfly lovers).Intervention were given to the pregnant rats roundly from the gestation until parturition.These results showed that,to some extent,music stimulations during gestation may promote the development of brain function and improve spatial memory of the offspring rats.However,expressions of some functional receptors were not significantly altered.Conclusions Appropriate music provided to the pregnant rats promote the development of brain functions in their offspring.

Objective To evaluate the value of the fusion of 99m Tc-MIBI imaging technology apply in the diagnosis of malignant lung tumor. Methods Thirty - four cases with lung nodules proved by X-ray and/or CT scanning, a total of 48 lung nodular lesions. And the imaging with-99m Tc-MIBI of chest performed at 10 minutes and 2 hours delayed after injection by GE Infinia Hawkeye 4 SPECT-CT. then the regions of interesting ( ROI) were drawn in the tumor and contra lateral position to calculate the radioactivity ratios of tumor to normal ( T/NT) , and fused with the spiral CT scanning image in the same machine, and reading the early and delayed image respectively. Judged the result of the image develops, and statistical analysis of the ratio (T/NT) according to the final pathologic consequence. Results All cases with total of 48 nodular lesions, 21 nodules were positive in early imaging, 16 nodules were positive in delayed imaging (the ratio T/NT over 3. 33). defined the delayed image positive as the final criterion, The(T/NT)ratios of Malignant lung lesions were significantly higher than the benign lesions ( P ＜0. 05). Negative nodes 27, 13 cases of lung cancer lesions were malignant, confirmed by postoperative pathologic examination. The falsepositive nodules 3, false-negative nodules 2. The sensitivity was: 88.88%, the specificity was: 90.9% positive predictive value ( +PV) was: 84. 21% , negative predictive value (-PV) is: 93.75%. Conclusion 99mTc-MIBI as a tumor positive imaging agent is highly sensitivity to lung lesions, but specificity is not so high.

AlM:To investigate the effect of cyclosporine A ( CsA) on the phosphatidylinositol-3 kinase ( Pl-3k ) pathway during procession of proliferation in epithelial cells of rabbit lens, and provide treatment strategies for after cataract on the basis of experiment.
METHODS: Sixty eyes of 30 healthy white rabbits were operated by lens cortex removal in cataract surgery, and 30 right eyes were divided in treatment group and the other 30 eyes were divided in control group. From the first postoperative day, the control group eyes were dropped with normal saline 6 times each day, and the treatment group eyes were dropped with 1% CsA 6 times each day. Six rabbits were selected randomly and killed on the day before dropping and 1, 2wk, 1 and 2mo of postoperative day respectively. The lens of those killed rabbits were removed by surgery. The strategies of immunohistochemistry and mount in situ hybridization were used to detect the content of proliferating cell nuclear antigen ( PCNA) , gene of phosphate and tension homology deleted on chromsome ten ( PTEN) mRNA, Ser473-R, respectively.
RESULTS:The expression of PCNA and Ser473-R were both down-regulate after operation in treatment group and control group, and the PCNA levels were significantly lower among treatment group than those in control group on 1wk (0.690±0.035 vs 0.785±0.015, t=6.099, P<0.01) and 2wk (0. 571±0. 038 vs 0. 670±0. 037, t=4. 585, P<0. 01). ln addition, the levels of Ser473 - R were significantly lower among treatment group than those in control group on 1wk (0.374±0.031 vs 0.435±0.030, t=3.486, P=0.006) and 2wk (0. 220±0. 022 vs 0. 251±0. 020, t=2. 516, P=0. 031). However, the expression levels of PTEN mRNA were continually increased 1wk~1mo after operation, in which the expression levels of PTEN mRNA were significantly higher among treatment group than those in control group on 1wk (0. 302±0. 027 vs 0. 255±0. 038, t=2. 474, P=0. 033).
CONCLUSlON:1% CsA could inhibit the proliferation of epithelial cells in lens of rabbits with after cataract through preventing Pl-3k pathway.
