Objective To observe the clinical efficacy of cerebral palsy children with liver strong spleen weak syndrome treated with integrated traditional Chinese medicine therapy. Methods Eighty cerebral palsy children with liver strong spleen weak syndrome were divided into treatment group (40 cases) and control group (40 cases). Patients in control group were treated with conventional therapy (including exercise therapy, occupational therapy, guidance education, physical factors, and psychological therapy), and patients in treatment group were treated with integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) additionally. Three months were set for a course of treatment, and the whole treatment lasted for a total of four courses. TCM clinical symptoms were scored every six months, muscle tone (MAS), gross motor function (GMFM), and daily life activity ability (MBI) were evaluated every three months for both groups. Results There were significant differences in the total scores of TCM clinical symptom, MAS, GMFM, and MBI at different treatment time points in the two groups, compared with that before treatment (P<0.01). There were significant differences in the total scores of clinical symptom for Chinese medicine, MAS, GMFM, and MBI at different treatment time points for treatment group, compared with that of control group (P<0.05). Conclusion Integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) for cerebral palsy children on the basis of western medicine therapy can more effectively improve function and life quality of children patients.

Objective To observe the effect of spleen-warming and kidney-tonifying therapy on Toll-like receptor 4 (TLR4) signaling pathway of cerebral infarction sequelae patients. Methods A total of 60 cerebral infarction sequelae patients with spleen and kidney(yang) deficiency were divided into control group and treatment group, 30 cases in each group. The two groups were given function rehabilitation training following by the theory of modern rehabilitation medicine, and additionally the treatment group was treated with spleen-warming and kidney-tonifying herbs orally. The treatment period for the two groups averaged 3 months. Before and after treatment, the scores of traditional Chinese medicine (TCM) symptoms and signs, peripheral blood TLR4 mRNA expression level, and the inflammation-related factors in the two groups were observed, and the observation parameters were compared with 30 healthy volunteers. Meanwhile, the changes of modern rehabilitation evaluation indexes were also evaluated before and after treatment. Results (1) After treatment, the Fugl-Meyer scores for motor function and Modified Barthel Index(MBI) scores for activities of daily living in the treatment group were obviously increased(P < 0.05 or P < 0.01 compared with those before treatment); the MBI scores in the control group was much increased(P < 0.05 compared with those before treatment), but the Fugl -Meyer scores only showed an increasing trend(P > 0.05). (2) After treatment, the predominant symptoms and signs of hemiplegia, facial distortion and dysphasia in the two groups were much improved(P < 0.01 compared with those before treatment), and the improvement in the treatment group was superior to that in the control group(P < 0.05). The control group had no significant effect on relieving the symptoms and signs of dizziness and blurred vision, numbness of limbs, spontaneous sweating, shortness of breath and weakness, and darkish tongue(P > 0.05 compared with those before treatment); the treatment group had obvious effect on the above symptoms and signs, and the effect was superior to that in the control group(P < 0.05 or P < 0.01).(3) For the inflammation-related factors, tumor necrosis factor alpha(TNF-α) level in the treatment group was much decreased and even arrived to the normal level(P > 0.05), and TNF-α level in the control group was decreased but did not arrive to the normal level(P < 0.05); levels of interleukin(IL)-1β, IL-6 and TLR4 mRNA in the two groups were decreased but did not arrive to the normal(P < 0.01), and the decrease in the treatment group was superior to that in the control group(P < 0.05 or P < 0.01). (4) During the treatment period, no obvious adverse effect was found in the two groups. Conclusion Oral use of spleen -warming and kidney –tonifying Chinese medicine combined with modern rehabilitation therapy is effective for the treatment of the sequelae of cerebral infarction patients by relieving the clinical TCM symptoms, and one of the therapeutic mechanisms is probably related with the TLR4 signaling pathway through regulating the expression of inflammatory factors.

A total of 30 cats were used in this experiment.The nucleus raphe magnus wasinjected with 0.1～0.3?l of 25～50% HRP solution(RZ:2.4～3.1).Two or three daysafter operation,the animals were killed and then perfused with the fixing fluid.Thebrainstem and spinal cord were sectioned serially on a freezing microtome and treatedaccording to the method of retrograde axonal transport of horseradish peroxidase.Parts of the sections were counterstained with toloidine-blue.The labelled neuronswere examined microscopically under bright-field and dark-field illumination Thelabelled neurons were distributed as follows.After injections of nucleus raphe magnus,a few labelled neurons were foundin the medial part of parafascicular nucleus of the thalamus.A greater numbers oflabelled cells were consistently found in the ventrolateral area of the central greymatter of the midbrain.The dorsal nucleus of the midbrain raphe had a few labelled neurons.The HRPpositive neurons were found in the nucleus Darkschewitsch,mesencephalic reticularformation,nucleus reticularis gigantocellularis,nucleus reticularis paramedianus,nucleus vestibularis medialis and nucleus vestibularis lateralis.In some cases a fewlabelled cells were also seen in the posterior area of hypothalamus,nucleus posteriorcommissure,nucleus tegmentalis dorsalis,superior collicus,nucleus annularis,reticularformation of the pons,nucleus nervi facialis and nucleus gracilis.In summary,the present studies show that the afferent connections of nucleusraphe magnus are widely concerned with the structures of the pain control.Itsuggests that the nucleus raphe magnus is an important relay station for pain control.
