Chinese Journal of Physical Medicine and Rehabilitation 2010;32(6):405-408
Objective To investigate the effects of electro-acupuncture (EA) combined with repetitive transcranial magnetic stimulation (rTMS) on protein kinase A-cyclic adenosine monophosphate response element binding protein (PKA-CREB) signal transduction system after focal cerebral ischemia in adult rats and to explore the mechanism of EA combined with rTMS in treating ischemic brain injury.Methods The animal model of transient focal ischemia was made by artificial middle cerebral artery occlusion. Seventy-five Wistar rats were randomly divided into normal group, model group, EA group, rTMS group and EA+rTMS group. The expressions of PKA and pCREB in hippocampus were detected and the neurologic impairment rating was observed at the 7th, 14th and 28th days, respectively, after infarction.Results The average gray densities of PKA and pCREB expressions in hippocampus after focal cerebral ischemia in model group were higher at the 7th d, lower at the 28th d than that in normal group (P<0.05);higher in EA group, rTMS group, EA+rTMS group than that in model group at all time points (P<0.05), higher in EA+rTMS group than that in EA group and rTMS group at 7th and 14th d(P<0.05), and there was no difference between EA group and rTMS group(P>0.05).The improvement of neural motor function was obvious in EA group, rTMS group and EA+rTMS group compared with model group (P<0.01), especially in EA+rTMS group.Conclusions EA combined with rTMS can promote the functional recovery after cerebral ischemia,enhance the expression of PKA-CREB signal transduction system in hippocampus after focal cerebral ischemia, which might be one of the important mechanisms of EA combined with rTMS in treating ischemia brain injury.

Chinese Journal of Physical Medicine and Rehabilitation 2004;0(01):-
Objective To study the effect of electroacupuncture(EA) combined with transcranial magnetic stimulation(TMS) on the angiogenesis in rats with cerebral ischemia. Methods Fifty-five male Wistar rats were randomly divided into five groups: a normal group, a model group, an EA group, a TMS group and an EA plus TMS group. After the establishment of acute middle cerebral artery occlusion (MCAO), the rats in various groups were accordingly treated with EA, TMS or EA plus TMS, respectively. Then the expression of VEGF164 mRNA and CD31 was observed. Results The expression of VEGF164 mRNA and CD31 around the infarction locus of the three treatment groups increased, especially in the EA plus TMS group. Conclusion EA plus TMS can increase the expression of VEGF164 mRNA and CD31 around the infarction locus and promote the non-molecular angiogenesis in rats with cerebral ischemia.

5.Recent advances in surface modification of magnetic iron oxide nanoparticles and their applications for CTCs separation
Chinese Journal of Clinical Oncology 2014;(1):56-59
Magnetic iron oxide nanoparticles (MIONs) have been widely used in biomedical fields, including targeted drug deliv-ery, magnetic resonance imaging, separation and enrichment of cancer cells, and tumor-targeted therapy. However, MIONs are increas-ingly necessary to ensure reduced toxicity, more stable colloidal dispersion, better biocompatibility, and higher magnetic responsive-ness. Thus, apart from the continuous improvement of material synthesis, specific surface modification of MIONs is essential to choose appropriate materials. This paper reviews the available methods and materials and their function in MION surface modification as well as their applications for the separation of circulating tumor cells.

Objective To measure and compare sevoflurane minimum alveolar concentration (MAC)in newborn and adult rats.Methods The rats were divided into newborn rat (6-8 days) group (25 cases)and adult rat (8-10 weeks)group (25 cases).All rats were settled in the self-made device for anesthesia with inhaled sevoflurane,and the tails of rats were exposed out of the device. Sevoflurane was given via an anesthesia machine.Up-and-down method and clamping tail stimulus were applied to measure the MAC values of sevoflurane in the two groups.1.5% of sevoflurane was set as the initial concentration,and± 0.2% as adjustable gradient.A positive or negative response was judged by clamping tail stimulus in a 20 minutes interval.The mean MAC value of all rats in each group was defined as the MAC value.Results The MAC value of newborn rats was (2.58 ± 0.1 1)%,and the MAC value of adult rats was (2.32 ±0.13)%.A significant difference was found between the two groups (P <0.01).Conclusion The MAC value of newborn rats was much higher than that of adult rats.Newborn rats need a higher concentration of sevoflurane at the same depth of anesthesia when compared with adult rats.

A non-invasive acoustical system was developed for the measurement of transmission properties of acoustic waves in the hip joints. The instrumentation consisted of three sub-systems. An excitation system employed a vibratory force at the sacrum of the test subjects. A transduction system included a pair of identical microphones installed in the tubes of two stethoscopes, which were placed at the greater trochanters on both sides for picking up the acoustical signals transmitted across the hip joints. The data acquisition and analysis system was a portable signal analyzer with a program of dual channel digital filter for measuring the power of acoustical signal in 1/3-octave frequency bands. 27 normal adults, 20 normal pre-school children and 40 normal neonates were randomly selected for testing. Coherence function (CF) and discrepancy (D) was measured during the testing. Results from the three groups showed that there was a high coherence of the signals (CF > 0.9) and a small discrepancy (D < 3 dB) between bilateral hips in the frequency range of 200-315 Hz. For normal neonates, there was a wider frequency range of 160-315 Hz in which the acoustical signals maintained a high coherence (CF > 0.93) and a smaller discrepancy (D < 2 dB) was observed. This study showed that the development of the acoustical technique provided a practical method with objective parameters. The results obtained in this study can offer a baseline for further investigation of hip disorders particularly those related to structural abnormalities of the hip.
