2.Group Lasso Penalized Classifier for Diagnosis of Diseases with Categorical Data.
Journal of Biomedical Engineering 2015;32(5):965-969
Six kinds of erythemato-squamous diseases have been common skin diseases, but the diagnosis of them has always been a problem. The quantitative data processing method is not suitable for erythemato-squamous data because they are categorical qualitative data. This paper proposed a new method based on group lasso penalized classification for the feature selection and classification for erythemato-squamous data with categorical qualitative data. The first categorical data of 33 dimensions were changed by the virtual code, and then 34th dimension age data were discretized and changed by the virtual code. Then the encoded data were grouped according to class group and variable group. Lastly Group Lasso penalized classification was executed. The classified accuracy of 10-fold cross validation was 98.88% ± 0.002 3%. Compared with those of other method in the literature, this new method is simpler, and better for effect and efficiency, and has stronger interpretability and stronger stability.

The diversity of immune repertoire (IR) is closely related to immune function and tumors derived from B or T lymphocytes.In recent years,the development of next generation sequencing has greatly promoted the progression and application of IR analysis.The research of IR has become a new hotspot of the American Society of Hematology Annual Meeting in 2016.Relevant reports in this meeting will be reviewed together with advances in research and application of IR analysis in hematological malignancies in recent years.
5.Effect of Oxymatrine on cardiac function and left ventricular remodeling in rabbits after acute myocardial infarction.
Chinese Journal of Applied Physiology 2015;31(2):123-126
OBJECTIVETo observe the effect of Oxymatrine on left cardiac function and ventricular remodeling in rabbits after acute myocardial infarction.
METHODSLigation of the left anterior descending artery was adopted to establish acute myocardial infarction model, forty eight rabbits were randomized into the sham operation group, model group and Oxymatrine group. Eight models were successfully established in each group. the sham operation group and model group were given conventional feed. Oxymatrine were gavage administration 0.5 ml/100 g, once a day, lasted for 4 weeks. Respectively in postoperative week, and three weeks, to observe the Oxymatrine on cardiac output (CO), left ventricular end systolic pressure (LVESP), left ventricular end-diastolic pressure (LVEDP), left indoor pressure change rate peak (dp/dtmax)), and left ventricular cavity internal diameter (D), ventricular weight index (VWI), ventricular weight (VW).
RESULTSLeft ventricular anterior wall was from red to deep purple, electrocardiogram showed II guide ST-segment camber up ≥ 0.25 mv. Postoperative week in Oxymatrine group compared with model group, LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P < 0.01); After three weeks in Oxymatrine group compared with model group, VW, VWI decreased (P < 0.05), D significantly reduced (P < 0.01); LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P <0.01); dp/dt(max), CO increased (P < 0.05).
CONCLUSIONAfter acute myocardial infarction in rabbit Oxymatrine can improve the left ventricular reconstruction parameters, increase cardiac output, and improve cardiac function.

Malignant gliomas cells grow invasively with no clear boundary,and a complete resection surgery is very difficult,and the pathological type is not sensitive to radiotherapy and chemotherapy,so the overall treatment effect is not ideal,and this disease is very prone to local recurrence after treatment.The treatment of malignant glioma is mainly composed of surgical resection with postoperative radiotherapy and chemotherapy.Other new treatments include targeted therapy,immune therapy,gene therapy and so on.

Background:Small bowel Crohn's disease (CD) is a chronic nonspecific inflammatory disease with unknown etiology.There is no clear criteria for assessing the progression of CD, and the endoscopic index for assessing disease activity in CD patients is limited to a single parameter.Aims:To investigate the clinical value of endoscopic index in evaluating disease activity in patients with CD and the correlation between different parameters.Methods:Sixty cases of CD patients form Jan.2008 to Dec.2012 at Affiliated Hospital of Yanan Uuiversity were collected, 60 healthy adults were served as control group.CECDAI score, CDAI score and Lewis score were used to evaluate disease activity in patients with CD, and their relationship with CRP and ESR were analyzed.Results:Levels of CRP and ESR were significantly increased in CD patients than in controls (P<0.05).CDAI score and Lewis score were statistically different in different CECDAI score groups (F=5.53, P<0.05;F=22.64, P<0.05).CECDAI score was statistically different in different CDAI score groups (F=3.55, P<0.05), and was statistically different in different Lewis score groups (F=4.26, P<0.05).CECDAI score was correlated with CDAI score, Lewis score, CRP, ESR (P<0.05);CDAI score was correlated with CRP, ESR (P<0.05) and not correlated with Lewis score (P>0.05);Lewis score was not correlated with CRP, ESR (P>0.05) in CD patients.Conclusions:CECDAI score, CDAI score, Lewis score, CRP, ESR can reflect disease activity of CD, and can be used together to assess disease activity of CD patients.

In recent years, the development and widespread application of transcriptome sequencing (RNA-seq) technology has provided powerful tools for direct sequencing and identification of possible fusion transcripts. With the increase in reports of large caese about RNA-seq, the real fusion gene map of hematological malignancies revealed by RNA-seq is becoming clearer. This article introduces the related research progress in conjunction with the reports at the 62nd American Society of Hematology Annual Meeting.

Objective:Occult breast cancer (OBC) accounts for 0.3%-1.0%of all breast cancers. Because of the rarity of this dis-ease, its treatment and prognosis remain unclear. Our study evaluated the treatment outcomes and prognostic factors associated with OBC. Methods:A total of 82 patients diagnosed with OBC based on available criteria were treated at the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing, China, between January 1968 and June 2014. Except for 16 patients who were treated by needle biopsy or excisional biopsy only and were subsequently excluded, all of the cases reported were included in the study. Of the remaining 66 patients, one was male. Patient data, tumor characteristics, and treatment and outcome variables were evaluated. Overall survival (OS) and disease-free survival (DFS) were analyzed. A unicentric retrospective review of 66 patients with OBC was performed. Re-sults:The median follow-up was 75.5 months (7.0-328.0). No significant differences in OS and DFS were observed between patients who underwent mastectomy plus axillary lymph node dissection (Mast+ALND) and those who underwent breast conservation surgery (P>0.05). Univariate analysis revealed that nodal status is a significant prognosis factor of DFS (P=0.031). Conclusion:No significant difference in treatment outcomes between mastectomy+ALND and breast conservation surgery was observed. Nodal status may be an independent predictor of poor outcomes in OBC patients.

Human embryonic stem cell (hES cells) lines can be derived from the inner cell mass (ICM) of preimplantation blastocysts.hES cells are commonly defined as undifferentiated pluripotent cells that can proliferate and have the capacity of both self-renewal and differentiation into one or more types of specialized cells.hES cells remain undifferentiated when culture on feeder layers,such as murine embryonic fibroblasts (MEFs).It is believed that various factors secreted from feeder layers are necessary to prevent hES cell from differentiation.In this review,we will summarize the advantages and disadvantages of various types of feeder cells by which a reference for future research will be provided.
