It is generally considered that various regulatory activities between genes are contained in the gene expression datasets. Therefore, the underlying gene regulatory relationship and the biologically useful information can be found by modeling the gene regulatory network from the gene expression data. In our study, two unsupervised matrix factorization methods, independent component analysis (ICA) and nonnegative matrix factorization (NMF), were proposed to identify significant genes and model the regulatory network using the microarray gene expression data of Alzheimer's disease (AD). By bio-molecular analyzing of the pathways, the differences between ICA and NMF have been explored and the fact, which the inflammatory reaction is one of the main pathological mechanisms of AD, is also emphasized. It was demonstrated that our study gave a novel and valuable method for the research of early detection and pathological mechanism, biomarkers' findings of AD.

A master-slave electrical impedance tomography (EIT) system for body complex impedance based on digital signal processor (DSP) is designed in this paper. Used as the master computer, a PC performs the image reconstruction and display on time, while DSP carries out such tasks as electrode selection, data acquisition and data communication with the master. Based on DDS technique, the signal generator can create the sine wave signals, and it's amplitude, frequency and phase can be continuously adjusted. The designed feedback unit can improve the linearity and the stability of the voltage-controlled current source effectively. Undersampling technology and digital demodulation technology are used in this system in order to attain the information of real and imaginary components of the body complex impedance. Back projection method is adopted to reconstruct the image in this system. Experimental results show that this system improves the data acquisition speed and the image resolution.

Objective:To explore the efficacy of abdominal acupuncture in treating patients with osteoporotic vertebral compression fracture (OVCF).
Methods:Forty-five eligible OVCF patients were randomized into an abdominal acupuncture (AA) group, a body acupuncture (BA) group and a medication group according to the random numbers generated by the SPSS 11.5 version software, 15 subjects in each group. Patients in the medication group were intervened by Ossotide injection (intravenous injection), Caltrate (oral administration), Alfacalcidol (oral administration), and Salcatonin injection (muscular injection). In addition to the intervention given to the medication group, patients in the AA group additionally received acupuncture at Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6), Guanyuan (CV 4), Shuifen (CV 9), and Huaroumen (ST 24); while patients in the BA group additionally received acupuncture at Jiaji (EX-B 2, superior and inferior to the affected area) points, Ashi points, Weizhong (BL 40) and Chengshan (BL 57). For the AA and BA groups, the acupuncture treatment was given once a day, 6 d per week, for 3 weeks in total. Prior to the intervention, and respectively after 1-week treatment, 2-week treatment and 3-week treatment, visual analogue scale (VAS) and Barthel index (BI) were adopted to evaluate pain degree and activities of daily living (ADL).
Results:After intervention, the VAS and BI scores were significantly changed in the three groups (P<0.05). Respectively after 1-week, 2-week and 3-week treatment, the VAS and BI scores in the two acupuncture groups were significantly different from those in the medication group at the same time point (P<0.01). After 1-week and 2-week treatment, the improvements of VAS and BI scores in the AA group were more significant than those in the BA group(P<0.05); after 3-week treatment, there was no significant difference in comparing the VAS score between the two acupuncture groups (P>0.05), but a significant difference was found in comparing the BI score (P<0.05).
Conclusion:Abdominal acupuncture can produce a more significant effect in improving VAS and BI scores in OVCF patients than body acupuncture and pure medication treatment, and it’s efficient and causes few sufferings.
