International Journal of Biomedical Engineering 2009;32(3):157-161
Since the transcranial magnetic stimulation (TMS) is a non-invasive technique to interfere neu-ral activity of brain, the combination of TMS and other neuron-imaging techniques has been widely used, espe-cially in cognitive research. Electroencephalogram (EEG) occupies a special position in this field due to its higher time resolution and lower experimental cost. The present paper reviews the application of TMS-EEG combined technique from the aspects of the main research topics, simultaneous recording, artifacts elimination, data pro-cessing and so on. Current problems and possible solution related to this technique are also discussed in the pa-per. With those new related solutions being put forward, more achievements will be obtained in the research area of TMS-EEG combined technique.

Objective:
To study common problems in BRAF gene mutation detection, and conditions for repetition testing using thyroid fine needle aspiration specimens.
Methods:
A total of 8 644 cases of thyroid fine-needle aspiration specimens at China-Japan Friendship Hospital were collected between February, 2012 and July, 2018. BRAF gene mutation was detected by real-time PCR. Repeat testing was performed in 237 cases when the results were inconsistent with clinical or cytological diagnosis or when uncertain results were obtained.
Results:
The final positive rates of BRAF mutation was 22.0% (1 897/8 625). Nineteen cases were excluded due to inadequate DNA samples. The average Ct value of internal quality control was 16.061, and the average Ct value of the positive samples was 19.147. Among 237 repeat tests, 51.4% (19/37) continued to have poor DNA quality and 48.6% (18/37) had adequate DNA resulting in 1 positive case and 17 negative cases. In 40 repetition of initial negative cases, results were unchanged. In initial positive cases, 40.4% (40/99) with a difference of Ct value (between BRAF gene and internal quality control) between 8 to 12 turned negative after repetition, 69.8% (37/53) of these cases with a difference of more than 12 turned negative after repetition. The sensitivity and specificity of BRAF mutation were 83.97% and 96.94%, respectively.
Conclusions
Difference between BRAF gene Ct value and internal quality control Ct value is recommended as a reliability index for the test result. Cases with a difference greater than 8 should be subjected to repeat testing.

Monotropein is a compound classified into iridoid which is found in herbaceous plants Morindae officinalis. It possesses anti-inflammatory, antioxidant, and anti-osteoarthritic activities. Previous study indicates that monotropein may have the potential to combat cardiovascular disease, although the related mechanism remains unclear. In this study, we constructed the model of atherosclerosis by oxidized low density lipoprotein-induced vascular smooth muscle cells and LDLR –/–mice given high-fat diet to investigate the effects of monotropein on atherosclerosis.Our results showed that monotropein treatment significantly reduced the area of atherosclerotic plaques and necrotic cores in mice, inhibited the proliferation and migration of vascular smooth muscle cells, and reduced inflammatory responses and oxidative stress, which in turn alleviated atherosclerosis. In addition, we found that monotropein reduced the expression levels of P-NF-κB and P-AP-1. In conclusion, our data suggest that monotropein inhibited the proliferation and migration of vascular smooth muscle cells by mediating the activity of NF-κB, AP-1, reducing the level of inflammation and oxidative stress, and thus resisting the development of atherosclerosis. These findings demonstrate the efficacious therapeutic impact of monotropein on atherosclerosis and elucidate its specific target.
