ObjectiveTo observe the clinical efficacy of moxibustion plus acupoint autohemotherapy in treating allergic rhinitis due to lung-spleen qi deficiency.MethodTotally 120 eligible subjects were divided by using the random number table into a comprehensive group, a moxibustion group and a Western medication group. The comprehensive group was intervened by moxibustion plus acupoint autohemotherapy, the moxibustion group was by moxibustion,and the Western medication group was by Loratadine tablets. The acupoint autohemotherapy was give twice a week and the rest treatments were given once a day, 7 das a course, for 4 courses in total. A follow-up study was conducted 3 months later. The clinic efficacy was evaluated before and after intervention, as well as in the follow-up study.ResultThe three groups all achieved significant short-term efficacies after intervention, and the comprehensive group was equivalent to the moxibustion group, bothsuperior to the Western medication group(P<0.05). According to the follow-up study, the long-term efficacies of the comprehensive group and moxibustion group were both significantly higher than that of the Western medication group (P<0.01,P<0.05), and the moxibustion group was superior to the comprehensive group in comparing the long-term efficacy (P<0.01).ConclusionMoxibustion plus acupoint autohemotherapy and dry moxibustion both can produce significant short-term and long-term therapeutic efficacies in treating allergic rhinitis due to lung-spleen qi deficiency. The long-term efficacy of moxibustion is higher than that of moxibustion plus acupoint autohemotherapy in treating allergic rhinitis due to lung-spleen qi deficiency. Acupoint autohemotherapy requires strict aseptic operation, which restricts its application in family healthcare. Long-term use of moxibustion can activate yang qi, and thus plays a role in preventing diseases.

Objective To investigate the effect of hirudo micropowder on inflammatory factors in rats with cerebral ischemia-reperfusion injury.Methods Rats were randomly divided into sham-operation group,model group,coarse powder hirudo group,high-,middle-and low-dose micropowder hirudo groups.The corresponding drugs were given to the rats for 10 days by intragastric administration.Then middle cerebral artery occlusion(MCAO) model was made by suture method.The changes of inflammatory factors were observed.Results The level of intercellular adhesion molecule 1(ICAM-1) in high-dose micropowder hirudo group was lower than that in coarse powder hirudo group,and the level of platelet-derived growth factor(PDGF) in middle-and high-dose micropowder hirudo groups was also lower than that in coarse powder hirudo group obviously(P

DC group.IL-12 secretion in IL-18/fusion group was higher than that in the fusion group,and IL-12 in the pulsed DC group was higher than that in the DC group.The in vitro killing rates of the 4 groups were 79.73%,50.68%,35.81% and 4.05%,respectively.Tumor forming time in IL-18/fusion group([12.82?2.85]d) was longer than those in the pulsed DC group([8.52?1.97]d,P

Four hours after the spinal cord of rats was injured,the contents of malondi-aldehyde(MDA)and free fatty acid(FFA)were significantly increased,the activity of xan-thine oxidase(XOD)elevated,the activity of superoxide dismutase(SOD)reduced,and the calcium content significantly increased in the tissues of the injured cord.These facts suggest that there is the generation of calcium-mediated free radicals and lipid peroxidation in the membrane.Intravenous injection of saponins of Panax notoginseng(PNS)in the dosage of 30,90,and 270mg/kg could all inhibit the production of MDA; 270mg/kg could inhibit the release of FFA and the activity of XOD;90mg/kg could significantly decrease the calcium content.These findings indicate that the inhibition of PNS on the calcium influx might be one of the mechanisms of anti-lipid peroxidation in spinal cord injury in rats.

0.05).The positive rates of CD1a and CD83 in IL-18+TNF-? group were higher than those in other 2 groups.The positive rate of HLA-DR in IL-18+TNF-? group was higher than that in IL-18 group.No difference between IL-18 group and TNF-? group in the potency of stimulating T cell proliferation was found,whereas the stimulating potency in IL-18+TNF-? group was higher than that in IL-18 group and TNF-? group.IL-12 in IL-18+TNF-? group at 48 h and 72 h was higher than that in IL-18 group and TNF-? group(P

Objective To observe the effects of valproic acid (VPA) on function recovery of injuried spinal cord with transplanted neural stem cell in adult rats. Methods 96 SD rats were divided into 4 groups randomly: the injury group, VPA group，NSCs group and NSCs+VPA group. All rats were hemi-sected at T10 level. The rats in VPA group were injected with VPA 300 mg/kg·d introperitoneally twice a day. Those in NSCs group were transplanted with absorbable gelatin sponge absorbing the identified NSCs. Those in NSCs+VPA group were dealed the same as those in NSCs group, and injected with VPA 300 mg/kg·d introperitoneally twice a day. They were assessed with Basso-Beattie-Bresnahan(BBB) scale and electrophysiology examination in 2nd, 4th and 8th week. The nuclear yellow retrograde tracing and DIL anterograde tracing were performed in 8th week. Results The number of neurons traced with DIL and nuclear yellow of NSCs+VPA group were more than that of other groups. The BBB scores and indexes of electrophysiology examination of NSCs+VPA group improved more than other groups, especially the motor evoked potentials. Conclusion VPA promotes neural stem cells transplant to repair the function of injuried spinal cord in adlut rats.

Objective To observe the differentiation of neural stem cells(NSC)into neurons under different astrocytes feeding layers.MethodsThe NSC purified from primary cultured clones and labeled by DAPI in serum-free media were plated in different feeding layers:cyto-plasma astrocytes and fibrous astrocytes respectively with Neural Basal(NB)media.After 10 d,immunohistochemistry with antibody NF-200 was taken to calculate the percents of neurons by 20 fields of vision chosen randomly.The differentiated neurons were stained with AchE and labeled with Fura-3AM.ResultsThe ratios of differentiated neurons in cyto-plasma and fibrous astrocytes were 72% and 43% respectively.In most differentiated neurons the AchE staining was positive and had the activity of Ca2+ stimulated by medicine.ConclusionThe cyto-plasma astrocytes can induced NSC differentiated into neurons,especially into active motor neurons,which can be chosen for a new seeding cells in the nervous tissue engineering.

Objective To explore the expression and change of ski-interacting protein (SKIP) in rats after spinal cord injury. Methods A total of 60 adult female Sprague-Dawley rats were randomly divided into sham group (n=30) and spinal cord injury (SCI) group (n=30), each group was further divided into five time points including one day, three days, five days, seven days, and 14 days with six rats in each time points. The model was established at T10 with modified Allen's technique, and the sham group only bit the lamina of rats. The hindlimbs behavior was assessed with Basso-Beattie-Bresnahan (BBB) score at each time point. The pathological changes of spinal cord neurons were detected with Nissl staining. The expression of SKIP were observed with immunofluorescence staining. Results The BBB scores were signif-icantly lower in each time point in SCI group than in the sham group (t>48.267, P<0.001). Compared with the sham group, Nissl bodies in the cytoplasm of spinal cord neurons began to disintegrate, coalesce and irregularly distribute, the neurons began to degenerate and die on the fifth day, and the damage deteriorated on the 14th day. Immunofluorescence staining showed that SKIP expression was mainly expressed in the gray matter of the spinal cord and little expressed in the white matter. The expression of SKIP gradually increased after SCI, and reached a peak on the fifth day (t=-17.035, P<0.001) and decreased significantly on the 14th day (t=3.853, P<0.05). Conclusion SKIP may be a new signaling molecule, which play an important role in neuronal apoptosis after SCI.

Objective To explore the expression and the changes of ski with time in the injured spinal cord in rats. Methods Sixty adult female Sprague-Dawley rats were randomly divided into sham group (n=30) and injury group (n=30), each group were further divided into 1 week, 2 weeks, 4 weeks, 8 weeks and 12 weeks subgroups, with 6 rats in each subgroup. Spinal cord injury at T10 was established with modi-fied Allen's technique (10 g × 25 mm) in the injury group. The hindlimbs behavior of rats was rated with Basso-Beattie-Bresnahan (BBB) scores 1 day, 3 days, 1 week, 2 weeks, 4 weeks, 8 weeks and 12 weeks after spinal cord injury. Three rats in each subgroup were stained with HE staining to observe the pathological changes of the spinal cord and the formation of cavity. The other 3 rats were analyzed with im-munofluorescence staining of ski and semi quantitative analysis. Results The BBB scores of each time point were less in the injury group than in the sham group (P<0.05). Necrosis was the major pathological change in the injury groups 1 and 2 weeks after injury;cystic cavity completely formed 4 weeks after injury, with dense scar tissue around it;there was no significant change in the cavity and scar 8 and 12 weeks after injury, however, the adjacent spinal cord was obviously thinner. Ski expressed little in the normal spinal cord, and expressed more and more after injury, peaked at 8 weeks and decreased then. Ski was mainly observed in white matter in the sham group and 12 weeks injury subgroup, which was in gray matter 2, 4 and 8 weeks after injury. Ski was highly expressed around the cavity in injury center and formed high expression band. Conclusion Ski expresses after spinal cord injury in rats, that may be associated with the activation and prolif-eration of astrocytes and the formation of glial scar.

Objective To explore the learning and memory impairment and pathology in hippocampus in rats after spinal cord contu-sion. Methods 36 adult female Sprague-Dawley rats were randomly divided into sham group (n=18) and spinal cord injury group (n=18). Spinal cord injury model at T10 was established with modified Allen's technique (10 g × 25 mm). The hindlimbs behavior of rats was rated with Basso-Beattie-Bresnahan (BBB) scores once a week for 5 weeks. They were tested with motor evoked potentials (MEP) and Morris wa-ter maze 5 weeks after injury. The pathology of hippocampus was detected with HE staining 1 week, 3 weeks and 5 weeks after injury, 4 rats in a group, repectively. Results The BBB scores were significantly lower in the spinal cord injury group than in the sham group at each time point (P<0.05). The latencies of both N1 and P1 wave of MEP were significantly longer in the spinal cord injury group than in the sham group (P<0.001), while the amplitudes were significantly less (P<0.001). For the Morris water maze, the latency of arrival platform were sig-nificantly longer in the spinal cord injury group than in the sham group (P<0.001), and the time in target was significantly less (P<0.001), with more systematic positioning or annular positioning, while the sham group with more space-based positioning. Morphologically abnor-mal cells in hippocampus gradually increased since the first week after injury, with the decrease of cells survival, while it was normal in the sham group. Conclusion Spinal cord contusion can cause learning and memory impairment in rats, which may be related to injury in hippo-campus.
