Meanwhile, molecular iodine with carrier gas of helium reacted with atomic chlorine to produce atomic iodine which then was pumped to excited state of I(2P1/2) by an energy transfer reaction from NCl(a1△). In this paper, the changes of NCl(a1△) and NCl(b1∑) emission intensity is presented when I2/He is introduced into the stream of Cl/Cl2/He/HN3/NCl(a1△)/NCl(b1∑). The dependences of atomic iodine I(2P1/2) on flow rates of gases were also investigated. The optimum parameters for I(2P1/2) production are given.展开更多

However, most studies of the underlying mechanism are at the single gene level; there are few reports regarding the mechanism at the whole-genome level. Using a rat genomic gene-chip, we profiled hippocampal gene expression changes in rats after electroacupuncture therapy. Electroacupuncture therapy alleviated depres- sion-related manifestations in the model rats. Using gene-chip analysis, we demonstrated that electroacupuncture at Baihui （DU20） and Yintang （EX-HN3） regulates the expression of 21 genes. Real-time PCR showed that the genes Vgf, lgf2, Trnp32, Loc500373, Hifla, Folrl, Nrnb, and Rtn were upregulated or downregulated in depression and that their expression tended to nor- malize after electroacupuncture therapy. These results indicate that electroacupuncture at Baihui and Yintang modulates depression by regulating the expression of particular genes.展开更多

The polyclinic's neonatology room was noise-controlled and made half-dark to prevent the perfusion index from being confounded. A pulse oximeter was linked to the baby's left lower extremity. Acupressure was applied on Yintang(EX-HN 3) for 30 s clockwise, held for 30 s, and then acupressure was applied for another 30 s counterclockwise. The baby's SaO_2, pulse rate, and perfusion index were recorded for each minute before and after acupressure.RESULTS: When pre- and post-acupressure pulse rate values were compared, a significant decrease in pulse rate values after acupressure application was observed. When pre- and post-acupressure oxygen saturation values were compared, a significant increase in post-acupressure oxygen saturation was observed. In addition, peripheral perfusion increased significantly after acupressure.CONCLUSION: Acupressure application has been used in traditional medicine for many years. However, it is not yet widely used in modern medicine.This study shows the impact of acupressure on neonatal skin perfusion, oxygen saturation, and pulse rate.展开更多
