Attention deficit hyperactivity disorder (ADHD) is the medical treatment, while it does not bring high compliance.Therefore, non-medical therapy is a research focus in this field.Non-invasive neuromodulation can regulate the functional state of central nervous system by electric, magnetic, or chemical approach through invasive equipment that is proved to be highly safe.In the clinical industry, non-invasive neuromodulation is a widely used physiotherapy in various types of neuropsychiatric disorders, and has received satisfying effects.On the contrary, the utilization of this technique on ADHD in clinical settings is still under the research stage.This review aims at elaborating the clinical progress of several non-invasive neuromodulation approaches on ADHD, so as to provide reference to future researches in this field.
2.Research advances in gene expressions and related signal transduction in the tight junction of intestinal epithelium
Chinese Journal of Clinical Nutrition 2010;18(5):310-316
The tight junction of intestinal epithelium plays an important role in maintaining the function of intestinal barrier and regulating the cell differentiation. The intestinal epithelial cells interact with neighboring cells and the extracellular matrix and then affect the epithelial barrier as well as the proliferation, polarization, and apoptosis of cells. As an important cell junction, the tight junction of intestinal epithelium participates in a series of signal transduction pathways including the classic cyclic adenosine monophosphate-protein kinase A-cyclic adenosine monophosphate response element-binding, inositol trisphosphate, Ras-mitogen-activated protein kinase, phosphatidylinositol 3-kinase, and in some special pathways including zonula occludents protein 1-associated Y-box factor,cyclin related protein, phosphorylation, and methylation. Furthermore, regulations of gene and protein expression of the tight junction are also complex, while disorders of such regulations may lead to clinical diseases, such as disruption of the intestinal barrier, refractory infection, and even cancers. This article reviews the research advances in gene expressions, related signal transduction, and self-regulation in the tight junction of intestinal epithelium.
3.Experiment study on traditional Chinese medicine used in depressive animal models
International Journal of Traditional Chinese Medicine 2010;32(6):553-554
Establishment of depressive animal model is the premise for evaluating the effect and mechanism of traditional Chinese medicine on depression. Many traditional Chinese medicines for depressive treatment in a mouse model of experimental studies have demonstrated a sound antidepressant effect, indicating that traditional Chinese medicine treats depression effectively. Therefore, more and more attentions have been paid in recent years. My article made a summary on depressive animal models of experiment study.
5.Applications of FRET technology in the study of mechanotransduction.
Journal of Biomedical Engineering 2013;30(6):1362-1367
Mechanical force has essential effects on cellular behaviors such as proliferation, migration and differentiation, and the mechanism of mechanotransduction is still one of the hot spots in mechanobiology study. Traditional methods could not provide accurate evaluation of the protein activation signal upon mechanical stress application. The development of fluorescence protein technology greatly promoted the understanding of mechanotransduction. In particular, genetically-encoded biosensors based on fluorescence resonance energy transfer (FRET) technique has achieved a real-time dynamic observation of living cell signal protein activity, which provides a powerful tool for the in-depth study of biomechanics. In this paper, we provide a summary on recent progress of FRET application in biomechanics. Firstly we introduce the FRET technology, and then we summarize three methods to integrate the mechanical stimulation with the FRET imaging system on cell experiments. After that, the important progress of biomechanical research on signal pathway made by FRET technology, such as cytoskeleton, Rho family, calcium and cellular physical stress visualization, are also discussed. Finally, we point out the bottleneck of the future development in FRET technology, and also make the prospect of the application of FRET in mechanotransduction. In summary, FRET technology provides a powerful tool for the studies of mechanotransduction, which will advance our systematic understanding on the molecular mechanisms about how cells respond to mechanical stimulation.

6.Analysis of government behaviors in county public hospital reform in Yulin of Shaanxi
Chinese Journal of Hospital Administration 2012;28(7):481-483
An investigation was made on reforrs of connty public hospitals in Yulin region,Shaanxi province.With theories of public administration,the authors probed into the government investment behavior in county-level public hospitals reform,hospital operation mechanism,and govemmem regulation,as well as multi-sector involvement in healthcare services Proposals made in the paper advocate constructing a responsible and limited service-based government in the county-level public hospitals reform.
7.Progress of standardized treatment in gastrointestinal surgery
Chinese Journal of Digestive Surgery 2012;11(1):19-21
With the change of diet and lifestyle,the development of medical concepts and techniques,the spectrum of disease has changed dramatically. The standardization of gastrointestinal surgery will be the key to further improvement.Endoscopic ultrasonography,computed tomography,magnetic resonance imaging, positron emission tomography-computed tomography and laparoscopy are helpful for preoperative staging of gastrointestinal carcinoma.The standards of operation,such as D2 lymph node dissection for gastric cancer and total mesenteric excision for rectal cancer,are also very important.Creating standards for multi-disciplinary treatment of gastrointestinal diseases will be important factors for improving outcomes.
8.A study on help-seeking behavior and treatment with mental illness
Chinese Journal of Behavioral Medicine and Brain Science 2012;21(2):155-157
ObjectiveTo explore help-seeking behavior and treatment towards people with mental illness,so as to provide evidence for intervention measures.Methods 1988 mental disorders in outpatient were selected with a self-developed questionnaire randomly,and regression analysis was carried out.ResultsUnstable marriages and the lack of mental health knowledge were risk factors for actively professional help-seeking contact after first onset of a mental disorder.Median delays of seeking help and treatment in depression,schizophrenia,anxiety disorders and somatoform disorders were 113.5 days,34.0 days,86.5 days,309.0 days and 6.0 months,3.0 months,3.0 months,5.5 months orderly.There were notable difference for primary treatment contact between the four mental disorders ( x2 =46.317,P =0.029 ).No-professional recognition ratio was 17.8%.The ratio of correctly diagnosed and rationally cured with drugs ratio was 10.5%.89.5% of outpatients had not been given rational drugs then they sought to psychiatry.ConclusionThe delay of help-seeking and treatment in mental illnesses are serious,so it should be taken effective measures to promote the popularization of mental health knowledge and train no-professional doctors in order to improve the behavior of seeking help and provide the ratio of recognition and treatment.
9.Effect of Gui-Zhi Fu-Ling Wan on HIF-1α and VEGF in Patients with Endometriosis
World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(5):1178-1181
This study was aimed to explore effect of Gui-Zhi Fu-Ling W an (GZFLW) on HIF-1α and vascular en-dothelial growth factor (VEGF) in patients with endometriosis. A total of 68 endometriosis patients in the First Peo-ple's Hospital of Xining from June 2011 to June 2013 were included. All patients received treatment of GZFLW, once a day. After one-month treatment, the treatment efficacy was analyzed. The endometrial tissues (both ectopic endometrium and eutopic endometrium) were obtained before and after treatment. The protein levels of HIF-1α and VEGF as well as the relationship of HIF-1α and VEGF were analyzed by SP immunohistochemistry. The results showed that the total treatment efficacy was 86.76%. Compared with pretreatment, the posttreatment protein levels of HIF-1α and VEGF were significantly reduced (P< 0.05). The decreasing of VEGF protein level and HIF-1α expres-sion level were positively correlated (P< 0.05). It was concluded that GZFLW had better efficacy in the treatment of endometriosis. One of the reasons may be the downregulation of protein levels of HIF-1α and VEGF in endometriosis tissues.
