The brain computer interface (BCI) can be used to control external devices directly through electroencephalogram (EEG) information. A multi-linear principal component analysis (MPCA) framework was used for the limitations of tensor form of multichannel EEG signals processing based on traditional principal component analysis (PCA) and two-dimensional principal component analysis (2DPCA). Based on MPCA, we used the projection of tensor-matrix to achieve the goal of dimensionality reduction and features exaction. Then we used the Fisher linear classifier to classify the features. Furthermore, we used this novel method on the BCI competition II dataset 4 and BCI competition N dataset 3 in the experiment. The second-order tensor representation of time-space EEG data and the third-order tensor representation of time-space-frequency BEG data were used. The best results that were superior to those from other dimensionality reduction methods were obtained by much debugging on parameter P and testQ. For two-order tensor, the highest accuracy rates could be achieved as 81.0% and 40.1%, and for three-order tensor, the highest accuracy rates were 76.0% and 43.5%, respectively.

Objective To study the use on curative effect of Chinese medicine Qingyitang in severe acute pancreatitis.Methods 132 cases of severe acute pancreatitis were randomly divided into 2 groups,The control group(n=62) and the treatment group(n=70).Routine treatment were given in both,otherwise,the Chinese medicine Qingyitang was used in the treatment group.The operation rate,the infection rate,the time of abdominal distension removing and fasting and being hospitalized were observed and compared between two groups.Results Every index of the treatment group was finer than the control group.Conclusions The Chinese medicine Qingyitang showes their protective effects on gut barrier function by alleviating the damage of intestinal mucosa and microecologic disturbance following acute pancreatitis.As a result,the chances of bacterial translocation and enterogenic infection declines.These preparation might raise the treatment effects,as a well,shorten the course of treatment.

Objective To investigate the methods of preoperation diagnosis and treatment of primary gastric lymphoma of mucosa-associated lymphoid tissue(MALT).Methods To analyze retrospectively the diagnosis and treatment of 54 cases of MALT lymphoma diagnosed surgically and pathologically.Results The most common symptoms were stomachache or discomfort.Of the patients with MALT lymphoma,85.2%(46/54)cases were diagnosed by preoperation gastroscopy with biopsy.Helicobacter pylori was found in 48 cases(88.9%).The overall resection rate for MALT lymphoma was 87%(47/54).The 5-year and 10-year survival were 77.1% and 72.9%,respectively.Conclusions It is obvious that MALT lymphoma is associated with Helicobacter pylori.Since no specific symptoms in gastric MALT lymphoma,the preoperative diagnosis is relied upon the application of gastrointestinal image,gastroscopy and repeated biopsy.The use of curative resection with the post-operative chemotherapy and/or radiotherapy to treat MALT lymphoma is reasonable.

The bystander effect(BE) plays an important role in the gene therapy of cancer by the herpes thymidine kinase/ganciclovir(HSV-TK/GCV) system.It enhances the therapeutic efficacy of this system.Up to now,the exact underlying mechanism of the bystander effect remains unclear.A large body of evidence has indicated a close correlation of the connexin expression and gap junction in the targeted cells to the bystander effect.Here the publications concerning the relationship of gap junction with the bystander effect in the HSV-TK/GCV treatment have been reviewed.The possible cell death signals that can be transferred through gap junction to induce the bystander effect are also discussed.
