We attempted to clarify whether there are functional connections through these projections. Methods. Motoneurons were antidromically stimulated by the muscle nerve and recorded intracellularly to examine the direct interaction between them, after the related dorsal roots had been cut. Results. Excitatory connections, demonstrated by depolarizing potentials in response to muscle nerve stimulation, were found between motoneurons innervating the same muscle or synergistic muscles, but never between motoneurons innervating antagonistic muscles. These potentials were finely graded in response to a series of increasing stimuli and resistant to high frequency (50Hz) stimulation. Conclusions.These results indicate that excitatory connections, with certain specificity of spatial and temporal distribution, occur in the spinal motoneurons. It is also suggested that electrical coupling should be involved in these connections and this mechanism should improve the excitability of the motoneurons in the same column.展开更多

It is transmitted by fecal-oral and respiratory contact.There are two types of vaccine, OPV （live attenuated virus） and IPV （inactivated polio virus）. Currently, there is a plan of vaccination until the age of 5 with OPV. The children vaccinated expel a virus （derived from the vaccine） to the environment, and some of the people that have oral contact with them, get vaccinated by the herd behavior. Nevertheless, taking into account the lately observed facts about the reversion to virulence of the oral polio vaccine during its circulation in the environment, a change in the current vaccination schedule is being contemplated, where the oral polio vaccine can be replaced by the inactivated vaccine. Nowadays, In Colombia the inactivated oral polio vaccine is recommended for children presenting immune deficiency who are vaccinated with IPV. These children do not expel poliovirus to the environment. This work presents a mathematical model that describes the dynamics of the infection in a population where the two types of vaccination are carried out. The population is divided into two groups of age and Michaelis-Menten interactions. Different strategies of vaccination are simulated and analyzed.展开更多

Methods： A total of 58 AS cases were randomized into a long snake moxibustion group and a Western medication group, 29 in each group. The cases in the former group received long snake moxibustion and Western medication, whereas cases in the latter group received Western medication alone. Results： The total effective rate in the long snake moxibustion group was 93.1%, versus 62.1% in the Western medication group, showing a statistical significance （P〈0.01）; after the treatment, the scores of Bath Ankylosing Spondylitis Disease Activity Index （BASDAI） and Bath Ankylosing Spondylitis Function Index （BASFI） were improved in both groups; however, the improvements of BASDAI and BASFI results in the long snake moxibustion group were more significant than those in the Western medication group （P〈0.05）. Conclusion： Long snake moxibustion and Western medication can significantly improve the clinical effect on AS, coupled with a remarkable effect in enhancing the patients＇ functions.展开更多

Both of the two groups were treated by oral administration of Sulfasalazine tablets. Additionally, the treatment group was given moxibustion on Governor Vessel, and the control group was given sham moxibustion. The treatment was given once every other day, 4 weeks constituted one course, 2 courses in total. Before treatment, after 1-course and 2-course treatments, the quantified scores of traditional Chinese medicine（TCM） syndromes and the symptoms scores recommended by AS International Society [including Bath ankylosing spondylitis disease activity index（BASDAI）, visual analogue scale（VAS）, Bath ankylosing spondylitis functional index（BASFI） and Bath ankylosing spondylitis metrology index（BASMI）] were respectively observed and recorded, and the change of safety item was monitored. Results： After 1-course and 2-course treatments, the quantified scores of TCM syndromes were obviously improved than those before treatment in the two groups（P〈0.05）, and the score was improved better in the treatment group than that in the control group（P〈0.05）. In comparison within the group, there were no statistical differences between the scores after 1-course treatment and 2-course treatment in the two groups（P〈0.05）. After 1-course treatment, the items of the symptoms scores were improved than those before treatment in the two groups（P〉0.05）. After 2-course treatment, the therapeutic effect was more remarkable in the treatment group, with a statistical difference between the two groups（P〈0.05）. During treatment, no obvious abnormality in all safety items was noticed in the two groups. Conclusion： Moxibustion on Governor Vessel can effectively relieve the clinical symptoms of AS patients, without obvious adverse reaction.展开更多
