Objective To explore the effect of an electromagnetic field (EMF) on the viability,proliferation and osteogenic differentiation of rats' bone mesenchymal stem cells (rBMSC).Methods Sinusoidal 1mT EMFs of 10 Hz,30 Hz,50 Hz and 70 Hz were administered to rBMSC for 2 hours per day during 2 weeks of cultivation.The cell viability was analyzed using live/dead assays.The cells' DNA was quantified to evaluate cell proliferation.Von Kossa staining was performed to study the mineralization of the extracellular matrix.The enzyme linked immunosorbent assay (ELISA) and immunohistological staining were employed to observe the synthesis of osteocalcin (OC) and bone morphogenetic protein-2 (BMP-2).Results Cell viability decreased under exposure to the 50 Hz and 70 Hz fields.The proliferation of rBMSC was elevated significantly in the 10 Hz EMF-treated group.The expression OC and BMP-2 was elevated after two weeks of 50 Hz EMF stimulation.Moreover,the mineralization of the extracellular matrix was found to be enhanced after 50 Hz EMF exposure.Conclusion Exposure to a 1 mT EMF has different effects on the viability,proliferation and osteogenic differentiation of rBMSC depending on the frequency.The data provide practical guidance for applying electromagnetic fields in bone regenerative medicine.

AIM: To investigate the effects of electrical stimulation of vagus nerve on gut injury following intestinal ischemia-reperfusion in rats. METHODS: 30 adult male Wistar rats subjected to bilateral cervical vagotomy were randomly divided into three groups (n=10 per group): (1) Intestinal ischemia-reperfusion group (group I/R): laparotomy and I/R induced by clamping arteria mesenterica superior for 1 h followed by reperfusion for 2 h. (2) Vagus nerve stimulation group (group VNS): laparotomy, I/R and electric stimulation with pulse train of constant amplitude 5V, pulse width 2 ms and frequency 1 Hz at the left caudal vagus ends for 20 minutes before and after occlusion. (3) Sham control group (group SC): sham operation and sham stimulation. Carotid artery was cannulated for mean arterial pressure (MAP) monitoring. A strip of small intestine was taken from distal end of ileum for light microscopic (LM) and transient electron microscopic (TEM) examination at the time of 2 h after reperfusion. Improved Chiu’s scale was used to quantitatively assay the damage degree. The levels of malondialdehyde (MDA) and TNF-? in plasma were detected. RESULTS: MAP in every group kept steady during ischemia, but decreased gradually with the prolongation in the time of reperfusion. MAP decreased more dramaticly in group I/R than that in group VNS (P

Objective To explore the advantages and disadvantages between the RapidArc plans and fixed-field IMRT plan (IMRT).Methods Ten cases of cervical cancer,aged 55 (36-70),who were to receive post-operative radiotherapy were selected randomly.Single arc (Arc 1),two arcs (Arc 2),and three arc (Arc 3) RapidArc plans and fixed-field IMRT plan were designed respectively in the Eclipse 8.6 planning system.The designing,treatment time,target area,and dose distribution of organs at risk by these 4 planning techniques were compared.Results The values of average planned treatment time by the Arc 1,Arc 2,and Arc 3 ten cases was 98,155,185,and 46 min,respectively.The values of average treatment time in the Varian IX accelerator were 2.15,3.32,4.48,and 6.95 min,respectively.The average mean doses were (48.99±1.08),(49.40±0.51) ,(49.51±0.62) ,and (48.65±0.92) Gy,respectively.The values of homogeneity index (HI) of target were 1.11±0.07,1.07±0.02,1.06±0.02,and 1.12±0.05,respectively.The values of eonformal index (CI) of target were 0.73±0.13,0.87±0.06,0.87±0.06,and 0.79±0.06,respectively.The doses at rectum,bladder,and small intestine calculated by IMRT plan were the lowest,and the doses at the femoral neck calculated by these 4 plans were similar.Conclusions The RapidArc plan is superior in dose distribution at target,HI,CI,and treatment time to IMRT,but IMRT plan is superior to RapidArc in planned dose calculation time and protection of organs at risk.However,in general,the RapidArc plan is better in clinical application than IMRT plan.

Objective To investigate the relationship between the level of mindfulness and the A-type behavior characteristics of the nursing college students.Methods 172 nursing college students were investigated by the scale of TABP and FFMQ.The results were analyzed.Results In the 172 nursing college students,there were 112 nursing college students belonging to type B behavior pattern,accounted for 65.1％,and 60 nursing college students belonging to type A behavior pattern,accounted for 34.9％.The correlation between the score of TABP and the observation items and describing items were positive statistically significant,and was negatively correlated with awareness items and non-judge items statistically.Conclusions The students with different behavior characteristics were different in their mindfulness level.In order to improve nursing college students' mindfulness level and their mental health,the educators should take intervention based on their behavior characteristics timely.

Objective To observe the developmental changes of projection and termination of proprioceptive afferent fibers in the mouse spinal cord. Methods Parvalbumin (PV) immunohistochemistry was used to label the proprioceptive afferents. Single and dual immunofluorescence histochemistry were used to examine the growth pattern of proprioceptive afferents and their relationships with motoneurons in the spinal ventral horn (VH). The stained sections were observed under a confocal laserscanning microscope. Results PV-like immunoreactive (LI) proprioceptive fibers first appeared in the dorsal column on embryonic (E) day 14, then entered the gray matter on El5 and reached the intermediate gray matter and VH more obviously on E16. The number and intensity of PV-LI proprioceptive afferent fibers and punctata increased in the VH with age and reached a maximum during earlier postnatal (P) period (P0-P7). After P14, the number and intensity of proprioceptive afferents gradually decreased. The proprioceptive terminals seemed to form close relationship with motoneurons from E17. Conclusion The present study indicates that the somatotopic organization of proprioceptive afferents in the spinal cord is established during the late embryonic and early postnatal stages. These results provide evidence for understanding the development of the reflex movements.

The present study was designed to examine the developmental changes in projection and termination of nociceptive and proprioceptive afferent fibers in the spinal cord by labeling those two fibers with calcitonion gene-related peptide (CGRP) and parvalbumin (PV)separately in mouse embryos and neonatal pups aged embryonic day 15 to posanatal day 3 (E15 -P3). CGRP-like immunoreactive (LI)nociceptive fibers first appeared in the superficial dorsal horn (DH) at E16. The afferent projections extended laterally to the DH and entered into the deep portions of the DH at E17 and E18. After birth, the projection pattern of CGRP-LI fibers remained unchanged but the intensity of afferent terminals increased in the superficial laminae and their branching patterns became more complicated. In addition,CGRP-LI collaterals that projected into the contralateral DH were also examined after E16. Around birth, the contralateral projections were also found originated from the lateral part of the DH. PV-LI proprioceptive afferents were first observed entering the gray matter at E15 and reached the intermediate gray matter (IG) and the ventral horn (VH) more obviously on E16. The number and intensity of PV-LI fibers increased in the the VH with age and reached a maximum during earlier postnatal period ( P0-P3 ). The proprioceptive terminals seemed to form close relationship with motoneurons in the VH from E17. Our results indicate that the somatotopic organization of nociceptive and proprioceptive afferents in the spinal cord both are established during the late embryonic and early postnatal stages. These results help to understand the development of the sensory transmission in more details.
