ABSTRACT
<p><b>OBJECTIVE</b>To observe and evaluate the clinical efficacy of transcutaneous vagus nerve stimulation (taVNS) at auricular concha for primary insomnia (PI) and affective disorder.</p><p><b>METHODS</b>A total of 35 patients who met the diagnosis standard of PI in(5th edition) were included. The self-developed auricular vagus nerve stimulator (TENS-200A) was applied at auricular concha, 30 min per treatment, twice a day, 5 days a week for consecutive 4 weeks. The follow-up visit was conducted at the end of 6th week. The Pittsburg sleep quality index scale (PSQI), 17-items Hamilton depression scale (17HAMD) and Hamilton anxiety scale (HAMA) were applied for evaluation. The PSQI, HAMA and 17HAMD were observed before and after treatment; the safety was also observed.</p><p><b>RESULTS</b>Compared before treatment, the PSQI was significantly decreased to (13.20±3.61) at the end of 2nd week (<0.05); compared before treatment, the 17HAMD and HAMA were significantly decreased at the end of 4th week and 6th week (all<0.05). No adverse reaction was observed.</p><p><b>CONCLUSIONS</b>The taVNS could not only relieve PI symptoms, but also improve the depressive and anxiety symptoms, in addition, it may have positive long-term efficacy and safety.</p>
ABSTRACT
Chemokines have corresponding expressions in different tumor growth,metastasis or inhibition,and they may become the important standard of diagnosis and markers of prognosis for tumor in the future.Application of chemokine is especially important for the evaluation of tumor in clinical.By means of the studies of different expressions of chemokines in various tumors,it will be more in-depth understanding of tumors in micro-fields.Combined with clinical,the appropriate methods and means on targeted treatment can be taken for different tumors.
ABSTRACT
Lipoxygenases (linoleate: oxygen oxidoreductase, EC 1.13.11.12; LOXs) are encoded by a multi-gene family in plants. The LOXs are monomeric non-heme, non-sulfur iron dioxygenases, which catalyze the incorporation of molecular oxygen into polyunsaturated fatty acids containing a cis, cis-1,4-pentadiene moiety. The LOX isoforms are distinguished by differences in optimum pH of the reaction, pI, substrate and product specificity, spatial and temporal expression, and subcellular localization. The function of various LOXs in plants has been suggested. Some of the physiological processes in which lipoxygenases have been implicated include wounding, pathogen attack, seed germination, fruit ripening, plant senescence, and synthesis of Abscisic acid (ABA) and Jasmonic acid (JA). During normal vegetative and reproductive growth, lipoxygenases have also been suggested to act as vegetative storage proteins, participate in transference of lipoid, and response to nutrient stress and source/sink relationships. Significant progress in understanding LOX families will be beneficial to the application of the LOX in crop breeding, research on new-type phytoalexin and food industry.
