The prevalence of elderly dementia and work-related back neck pain is high, and so is the associated cost. Is dementia, which can take 20 - 30 years to develop, linked to musculoskeletal problems earlier in life? Classic Chinese Medicine Governor Vessel (GV) theory has in fact detailed a correlation, but its acceptance appears to be influenced and even limited by some inconsistences in the literature. This study involved a nationwide online questionnaire of 381 practicing acupuncturists to investigate GV's usage and impact on brain function. The survey covers areas of the acupuncturist's experience, perception of GV usage, related symptoms, needling concerns and correlations with brain function. 39 completed questionnaires werereturned, of which 38 were GV users, and nearly three quarters of respondents accepted that GV influences brain function. Only two respondents rejected this influence, but hereseveral inconsistencies were found. The associations with GV were predominately found to be with the spine, kidney, and brain. Indications from practitioners suggested numerous forms of clinical usage of GV, predominately on spinal, cognitive and qi-blood movement issues. GV influence on the brain was accepted by most respondents with only a few expressing uncertainty. Further worldwide, larger population, in-depth studies and trials are needed to fully establish and expand upon these findings.

Measurement of neutron cross sections and resonance parameters of <sup>169</sup>Tm below 100 eV
Wen-Ming, Wang,Xia, Li,Zhi-Xiang, Zhao,Zu-Ying, Zhou,Hong-Wei, Yu,Hai-Cheng, Wu,Yi-Xiang, Wei,Wang, T. F.,Kim, G. N.,Lee, M. W.,Kim, K. S.,Cho, M. H.,Ko, I. S.,Namkung, W. science press 2010 Chinese physics. C Vol.34 No.2
<P>The neutron total cross-sections of thulium (<SUP>169</SUP>Tm) were measured in the neutron energy region from 0.01 eV to 100 eV by using the time-of-flight method at the Pohang Neutron Facility, which consists of an electron linac, a water-cooled tantalum target with a water moderator, and a 12 m time of flight path. Two thulium plates with different thicknesses were used for the neutron transmission measurement. The background level was determined by using a notch-filter of Co, In, and Cd sheets. The present measurement was compared with the previous ones, and a new set of resonance parameters of <SUP>169</SUP>Tm isotope was obtained from the transmission rate by using the SAMMY code, with a comparison with the recommended parameters by Mughabghab.</P>

Emodin accentuates atrial natriuretic peptide secretion in cardiac atria
Zhou, G.H.,Zhang, F.,Wang, X.N.,Kwon, O.J.,Kang, D.G.,Lee, H.S.,Jin, S.N.,Cho, K.W.,Wen, J.F. North-Holland ; Elsevier Science Ltd 2014 european journal of pharmacology Vol.735 No.-
Emodin, an active anthraquinone constituent isolated from the rhubarb, a traditional Chinese herbal medicine which is widely used in clinical treatment, has cardiovascular protective properties. However, it remains unclear whether the cardiovascular protective actions of emodin are related to an activation of cardiac natriuretic hormone secretion. The purpose of the present study was to explore the effect of emodin on the secretion of ANP, a member of the family of cardiac natriuretic hormones, and its mechanisms involved. Experiments were performed in isolated perfused beating rabbit atria allowing measurement of ANP secretion, atrial pulse pressure, and stroke volume. Emodin increased ANP secretion concomitantly with a decrease in atrial pulse pressure and stroke volume in a concentration-dependent manner. These effects were reversible. Inhibition of K<SUP>+</SUP> channels with tetraethylammonium and glibenclamide attenuated the emodin-induced changes in ANP secretion and atrial dynamics. Furthermore, the emodin-induced changes in ANP secretion and atrial dynamics were attenuated by inhibition of L-type Ca<SUP>2+</SUP> channels with nifedipine. Atropine, methoctramine, tertiapin-Q, and pertussis toxin had no significant effect on the emodin-induced changes in ANP secretion and mechanical dynamics. The present study demonstrates that emodin increases ANP secretion via inhibition of L-type Ca<SUP>2+</SUP> channels through an activation of K<SUP>+</SUP><SUB>ATP</SUB> channel in isolated beating rabbit atria. The results also provide a rationale for the use of emodin in the treatment of impairment of the regulation of the cardiovascular homeostasis.
