Pathogen incubation theory includes "no manifestation after infection" and "manifestation after incubation". Clinical data showed that the incidence and recurrence of tic disorders in children had a strong relevance to six exogenous factors. The pathogenesis is similar to the pathogenic mechanism based on incubation of pathogen theory, so we proposed a theory of "tic disorder induced by incubation of pathogen". Pathogenic wind can be classified into exterior wind and endogenous wind. Pathogenic wind is more apt to move, rise and migrate. The characteristics of pathogenic wind, especially easy mobility, determine the symptoms and signs of tic disorder, for pathogenic wind can be characterized by vibration and involuntary movement such as convulsion and tremor. If exogenous pathogenic wind moves into half-exterior and half-interior phase from the exterior, both the exterior and interior syndromes should be treated at the same time. We should regulate the function of the liver and the lung, expel pathogenic wind by dispersing the lung, and calm endogenous wind by removing obstruction in the collaterals and soothing the liver.

To formulate clinical guidelines of diagnosis,syndrome differentiation,and standard treatment for children's tic disorder based on both domestic & foreign researching progress and our own many years researching results.We hope to provide reference for traditional Chinese medicine standardized treatment of children's tic disorder.

To evaluate the effects of Bushen Gubiao Recipe (BGR), a compound traditional Chinese herbal medicine, on toll-like receptor 4 (TLR4) signaling pathway and CD4(+)CD25(+)foxp3(+)regulatory T cells (CD4(+)CD25(+)foxp3(+)Tregs) in mice with recurrent respiratory tract infections (RRTIs).

Objective: To observe the effect of Shenfu Injection on carcinemia and study its mechanism.Methods: Mice C57 Lewis lung cancer model were established.The changes of physiological conditions(body weight,food and water intake),the serum levels of tumor necrosis factor-?(TNF-?),interleukin-6(IL-6) and interleukin-1(IL-1) were observed in the experiment.Results: Shenfu Injection can signifi cantly increase water and food intake of carcinemia mice,and inhibited the loss of body weigh(P

Objective To study the prevention effects of AduoLa Fuzhenglin(ADL)Oll the brain injury induced by microwave radiation in rats.Methods A total of 140 male Wismr rats were divided randomly into 5 groups,including control group,microwave exposed group,low dosage(0.75 g·kg-1·d-1)group.middle dosage(1.5 g·kg-1·d-1)group and high dosage(3 g·kg-1·d-1)group.Rats in three ADL groups were lavaged with ADL per day for 2 weeks before radiation.After administration,rats were exposed to microwave at 30 mW/cm2 for 15 min.The abilities of learning and memory were detected by Morris water maze,and the contents of amino acids neurotransmitter of hippocampus were detected by HPLC, then the histology and uhrastrncture of hippocampus were observed with light and electron microscope at 6 h,7 and 14 d after exposure.Results The abilities of learning and memory were declined(F=0.000-0.043,P<0.05)from 6 h to 7 d after exposure,and the contents of four kinds of amino acid neurotransmitter in hippocampus were decreased,of which GLU,GLY and GABA were decreased significantly(F=0.000-0.007,P<0.01)at 6h after exposure,then tissue edema,neuronal degeneration,neuron mitoehondria swelling and cavitation,endocytoplasmie rotieulum broaden,synaptic cleft blurred,and perivascular space widen were found in the hippocampus at 6 h and 7 d after exposure.The changes in low dosage group were similar to those of the radiation group.However,in middle and high dosage groups,the abilities of learning and memory were normal to some extent with the significant differences compared to the radiation group from 6 h to 7 d after exposure(F=0.015-0.028.P<0.05).The contents of four kinds of amino acid neurotransmitter were not decreased,especially GLU contents close tO normal level.There were significant differences between middle and high dosage groups and radiation group at 6 h after exposure(F=0.000-0.042,P<0.05).Moreover,no obvious injury in the hippocampus was observed in middle and high dosage groups at 6 h and 7 d after exposure.Conclusions Exposure to 30 mW/cm2 microwave radiation could decrease the abilities of learning and memory,induce amino acid neurotransmitter turbulence,and injure the histology and uhrastructure of hippocampus.ADL at the dosages of 1.5 and 3 g·kg-1·d-1 would have preventive effects on the injury induced by microwave exposure.The concentration of 1.5 g·kg-1 ·d-1 of ADL might be the effective dosage to prevent the brain damage after microwave exposure.

Objective:To assess the severity of hypoxic-ischemic brain damage (HIBD) in neonatal rats and predict the occurrence of subsequent neurobehavioral abnormalities after brain injury by scoring and magnetic resonance imaging (MRI).Methods:7-day-old of 60 Sprague-Dawley (SD) rats were randomly divided into control group (14 rats), sham operation group (14 rats) and HIBD model group (32 rats). HIBD model was established by right common carotid artery dissection with Rice-Vannucci method and hypoxia. Within 24 h after modeling, the rats in the model group were evaluated by general condition score and Longa score, and the surviving rats with moderate and severe HIBD were selected for the experiment. 24 h after modeling, 5 rats of the model group were randomly selected for 2,3,5-triphenyltetrazole chloride staining to verify cerebral infarction. 1 week after modeling, 6 rats from each group were randomly selected for hematoxylin-eosin staining to observe HIBD brain injury. 4 weeks after modeling, 4 rats were randomly selected from the control group and the sham operation group, and 8 rats from the remaining model group were used to evaluate the volume of brain damage by MRI. 5-6 weeks after modeling, the remaining 8 rats from each group were subjected to the Cylinder test, and at 13 weeks, they underwent the Morris water maze test to evaluate their neurobehavior.Results:In HIBD model group, 19 rats with moderate to severe HIBD were selected from 32 rats. 24 h after modeling, cerebral infarction was verified in all rats, indicating moderate to severe HIBD. Brain tissue pathology observed 1 week after modeling revealed predominantly gray matter brain damage. MRI showed that 7 out of 8 rats had moderate to severe HIBD. Compared to the control and sham operation groups, the model group exhibited a significant decrease in the usage rate of the left forelimb in the Cylinder test at 5-6 weeks after modeling ( P<0.05), and the latency period in Morris water maze test was significantly prolonged at 13 weeks after modeling ( P<0.05), and the times of crossing platform quadrant were significantly reduced ( P<0.05). There was no significant difference in the right brain injury volume between 24 h and 4 weeks model group ( P>0.05). The brain injury volume in model group was negatively correlated with the usage rate of left forelimb in cylinder test at 5-6 weeks and the times of crossing platform quadrant in Morris water maze test at 13 weeks ( P<0.05), and positively correlated with latency period in Morris water maze test at 13 weeks ( P<0.05). Conclusions:Within 24 h of HIBD modeling, the severity of brain injury can be preliminarily predicted by general condition score and Longa score. 4 weeks after modeling, in the chronic phase of brain injury, MRI was proved to be an excellent predictor for mid-term and long-term neurobehavioral abnormalities in HIBD rats.
